CyanogenMod 7 for Kindle Fire isn’t stable yet. We recommend waiting at least for a beta version. This version is for testing purposes only. It works only on Kindle Fire Software Version 6.0 and 6.1.

If you install CyanogenMod 7 you cannot go back to stock firmware and you will lose all of kindle Fire’s integration with Amazon.

If you still want to give it a try, here is a tutorial on how to install it.

Let’s get you started:

Step 1

Root your Kindle Fire

Step 2

Download CyanogenMod7 and place it at the root of your SD card so that its address is /sdcard/update.zip

Download ClockworkMod Recovery and place it to root of SD card as well.

Step 3

Download log and last_log and these under /catche/recovery as well as root of your SD card

Use the following adb commands to place log/last_log to /cache/recovery:

adb shell
cd cache
mkdir recovery
cd /
cp /sdcard/log /cache/recovery/
cp /sdcard/last_log /cache/recovery/

Step 4

We will now flash ClockworkMod Recovery. Use the following commands in adb:

adb shell
cd cache
mkdir recovery
cd /
cp /sdcard/log /cache/recovery/
cp /sdcard/last_log /cache/recovery/

To reboot into recovery, type:

idme bootmode 0×5001

If it say “bootmode has written”, type “reboot” to, well, reboot!

Your Kindle Fire will now boot into ClockworkMod Recovery (CWM).

Step 5

Press Power button on your Kindle Fire so you can install update.zip from SD card. /system, /data, and /catche will be wiped automatically. JackpotClavin modified CWM so that it would work with the Kindle Fire’s lack of buttons, so basically you just have to press the Power button a bunch of times.

In one of the menus, it’ll look like you have to scroll down to Yes. Instead, you must press Nobut it will, as the developer says, “mimic you pressing Yes”.

Step 6

After flashing CyanogenMod 7, the developer suggests reflashing the stock recovery. Download the stock recovery and use the following adb commands:

adb shell
mount sdcard
exit

Now, you must enter the correct path for where you’ve stored the stockrecovery.img file, so that your next adb command looks like this:

adb push <full path of file> /sbin/

Then,

dd if=/sbin/stockrecovery.img of=/dev/block/platform/mmci-omap-hs.1/by-name/recovery

Step 7: Wait for a minute and then type:

adb reboot

If you followed the steps correctly, your device will reboot into CyanogenMod 7.

Enable ADB access

If you would like to get intimate with your Kindle Fire you need ADB access, or Android Developer Bridge.

The first thing you need is the Android SDK and then add the Vendor ID for Amazon’s Lab126 9oX1949) to the adb_usb.ini file. Chances are that if you’re doing this, the previous sentence made perfect sense to you, but if not, a quick Google search will yield the information about the Android SDK that you require.

Step 1

Go to %USERPROFILE%\.android , once you’re there, edit the adb_usb.ini file and add the following line at the end:

0×1949

Save and exit.

Step 2

Navigate to the location where you have installed th Android SDK, oen the folder labeled google-usb_driver and hunt down the android_winusb.inf fileand under the following lines under the [Google.NETx86] and [Google.Ntamd64] sections:

;Kindle Fire

%SingleAdbInterface% = USB_Install, USB\VID_1949&PID_0006

%CompositeAdbInterface% = USB_Install, USB\VID_1949&PID_0006&MI_01

Save and exit the file. That’s it, you’re done with the ADB part.

Enable Root Access

Step 1

Plug in your Kindle Fire to your PC, we’re assuming you’ve already plugged it in since you did go through the above written ADB hassle.

Step 2

Open Device Manager from your PC, and under “Other Devices”; you should see the Kindle Fire, now select the android_winusb.inf file.

Step 3

Enable installation of apps from Unknown Sources. You can do so by tapping the top-most bar on your Kindle Fire and navigate to Choose More and head over to Device, over there you should see a listed device.

Step 4

Head over to this thread over at XDA and download the SuperOneClick tool.

Step 5: Run SuperOneClick and simply click on the Root button on the top-left of the tool, that’s all. You now have a rooted Kindle Fire with complete Superuser access.

Amazon has also given users the option of installing third-party apps onto the Fire, with just one option needing switching on in order to give apps the green light.

We’ll go through the drill one more time just to make it more clear on how to install third-party apps; head on over to Settings, and then Device. You’ll want to turn on ‘Allow Installation of Applications’ and hit OK when the warning box pops up. Amazon will warn about possible security risks, but we’re sure you’ll be fine with that given the plus side to installing your own apps.

The new version has minor application updates: Browser, Email, Gallery, MMS, Google.apk, Maps, Swype, Talk (doesn’t include Video Call) and Voice Search. Some annoying bugs were fixed like: Phone.In quadrant. This version doesn’t bring anything new to the table. The scoring in VooDoo LagFix is about 1350 and 1900+.

The best rooting method is CF Root – JVQ. We call also root the XXJVQ from CWM using SppedMod kernel.

Other compatible Kernels with JVQ:

SpeedMod K015h T19-300hz

DarkCore 2.8 JVQ

Recently a new app was released which allows you to install two different ROMs on your Samsung Galaxy S2 i9100.

The app is called SGS2 Dual-Boot Setup (LolBoot) and it allows you to install two ROMs on your Galaxy S2, and you can change between them any time you want.

The app can be found in Android Market:

Dual-Boot your Galaxy S2!

/!\ Requires root /!\
/!\ This is for the Galaxy S2 *ONLY* /!\

(i) please note:
——————–
the dual-boot itself is still kind of in experimental stage and there are still some incompatibilities with some ROMs and other quirks.

Currently there are over 30 ROMs available in the internet for Samsung Galaxy S and at least two or three may interest you. Thanks to this app you can now have two ROM’s on your phone.

We don’t recommend this app to average users because it is still in development, and you can mess up your phone for good if you don’t know what you are doing.

The app need a rooted Samsung Galaxy S2, and a flashed kernel witch should support dual-booting.

On HTC you can install up to 5 ROM’s at once. You can switch between them with a restart.

The app can be downloaded for free from Android Market:

Download SGS2 Dual-Boot Setup (LolBoot)

There is also a beta version of CyanogenMod 9 for Samsung Galaxy S users, and it is fully functional. Only one bug is known: it wipes your SD Card completely.

There’s a few fixes in the new build including adding missing dictionaries and removing duplicate keyboards. The build is ready for daily use and adds Google Wallet Support for your device.

Before we get started you need two things:

• CyanogenMod 9 Alpha 11
• Google Apps Add-on

The files can be downloaded from XDA – Developers: http://forum.xda-developers.com/showthread.php?t=1356228

Let’s get started:

Step 1

Hopefully you’ll already running an earlier version of CyanogenMod. If you are, skip to Step 3. If not, proceed to Step 2.

Step 2

Root your Nexus S or Galaxy S; you might have to Google around for the latter. It’s an easy task but with quite a few steps.

Step 3

Be sure Rom Manager(get it from Android Market)  is installed then open it on your device. Check that ClockWorkMod Recovery (the Samsung tutorial works on all phones)  has the latest version installed.

Step 4

Back up your data. While still in ROM Manager, scroll down and select “Backup Current ROM”. Once completed the backup can be found in your SD card under ‘clockworkmod’ directory. It may be a good idea to transfer this data to your computer in case you need to restore to an earlier state.

Step 5

Install ICS by selecting “Install ROM from SD Card” in the ROM Manager menu.

Step 6

Select “Wipe Data and Cache”.

Step 7

Select “Wipe Dalvik Cache”.

Step 8

Repeat the Steps 3 to 7, but this time with the Google Add-on files.

Your phone will automatically restart. After it reboots, you’ll be welcomed by the Ice Cream Sandwich set up screen. Remember, since this particular build is pre-rooted, you’ll have to restore from backup if you wish to revert to the Gingerbread version. For now, the build seems to be working great.

Next you can find a step by step tutorial on rooting and unrooting Samsung Galaxy S i9000 in just one click.

If you are a Windows user, you need to do two things:

• Download Samsung Drivers (for Windows 32 or 64bit, depending on what you are using)
• The rooting app needs Dot Net Framework Version 4 to work.

Let’s get you started:

Step 1

Make sure USB Debugging is on (Settings > Applications > Development).

Step 2

Download GalaxyS_I9000_One-Click_Root.

Step 3

Next, connect your phone to the computer and start the file you downloaded in step 2.

Step 4

Now click One Click Root 2.1 or 2.2 and follow the programs instructions. Please note that for One-click root 2.1, your phone needs to be running Android 2.1 Eclair and for One-click Root 2.2, Android 2.2 Froyo.

Step 5

If you are planning to unroot you Samsung Galaxy S i9000, follow all the steps, and in Step 4 click One Click Unroot.

Congratulations, you now own a rooted phone.

MotorolaOneClickRoot in theory works on all Motorola phones running GingerBread. Because of different reasons, we were unable to get our hands on all Motorola phones. The following phones can be routed with MotorolaOneClickRoot:

• Motorola Droid 3: the successor of Droid 2. The producers say it has a 30% faster graphics chip than its predecessor. It’s the first Motorola phone capable of recording 1080p full HD videos.
• Motorola Droid 2: this phone is the successor of Motorola Milestone. It comes with Android 2.2 Froyo.
• Motorola Droid X2: it comes with a 4.3-inch screen, with qHD resolution, 1GHz dual-core processor, 512MB of RAM and 8MP camera.
• Motorola Droid X: when Motorola launched this phone, said it will self-destruct if you try to root it. Well, MotorolaOneClickRoot didn’t manage to terminate it.

As I said earlier, this rooting method should work, on other Motorola phones, like: Droid Pro, D2 Global (when a new update will be released) and Droid Bionic.

Before we get started, you need some files:

Download MotorolaOneClickRoot.zip

Motorola USB Drivers Windows 32bit or Motorola USB Drivers Windows 64bit

Let’s get started:

Step 1

Make sure you installed the Motorola USB Drivers.

Step 2

Unzip MotorolaOneClickRoot into your computer.

Step 3

Make sure USB Debugging is ON. You can find it on your phone in Settings > Applications > Development.

Step 4

Connect the phone to the computer and select Charge Only.

Step 5

Run MotorolaOneClickRoot. If you have Windows Vista/7, right click on the .exe file and Run as Administrator.

Step 6

A command window will appear with several simple instructions. Follow them.

Step 7

After 3 steps, the phone will reboot. When it will boot back on, you are finished.

Congratulations! You now own a rooted Motorola phone.

The particular custom ROM it’s in its early stages of development, and certain apps crash from time to time. But if you don’t want to wait for the RC version, we posted a guide on how to get and install it.

Before you get started, make sure your phone is fully charged and you have at least 200 MB of free space on your microSD card. Also if your phone is not rooted, follow this link to root it: Root Galaxy S2 on Android 2.3.3.

Let’s get started:

Step 1

Make sure your device is rooted.

Step 2

Download ROM Manger (Premium) and install it.

Step 3

Launch ROM Manager and tap Flash ClockworkMod Recovery and select Samsung Galaxy S2. When asked for root permissions, allow it.

Step 4

When Step 3 is finished, boot into ClockworkMod recovery. Do this by opening ROM Manager and tap Reboot into Recovery.

Step 5

After the reboot, open ROM Manager again. Tap on Download ROM and select CyanogenMod Nightly after tapping on CyanogenMod. Be sure to choose the Google Apps option if you want Gmail/YouTube/Google Search apps to be pre-installed with the new ROM. ROM Manager will now download CM7 Nightly for your SGS2

Step 6

Once downloaded; it will ask you to Backup Existing ROM, Wipe Cache, Dalvik Cache. Tap yes!

Step 7

CyanogenMod 7 Nightly for your Samsung Galaxy S II will now be installed. Your device will be usable after automatic rebooting.

So, if you decide to root your Galaxy S2 on Android 2.3.3, follow this guide.

In a guide posted on XDA-Developers we found this:

“Following is a guide on how to perform the root. It is rather easy if you know the drill from other Galaxy devices, but if you are a complete beginner with Samsung phones or Android in general, please read very closely! Try to remember what you do, as likely in the future you’ll be using ODIN more often, to flash custom kernels, custom/leaked firmwares, etc.

Quick guide (for experienced users) 
- Reboot into download mode
- Using the attached Odin version, flash the attached XWKDD kernel as PDA. Do not use the PIT, do not have any options checked except for “Auto reboot” and “F. Reset Time”
- Wait for the device to reboot
- Use the “adb root” command to restart ADB in root mode, followed by “adb shell” to get a rooted shell; then you can manually push Superuser.apk / su, busybox, OR use SuperOneClick to finish the job for you.

Long guide (for beginners) 
- Download the attached ODIN file and extract the .zip file

- Download the attached XWKDD, but do NOT extract the .tar file 

- Download and extract SuperOneClick

- If you do not have Samsung’s KIES 2.0 installed, download and install it. You need it to install the correct USB drivers, so the programs can communicate with the device. Reebot your computer after installation of KEYS.

- Make sure your device is in USB debugging mode: Settings -> Applications -> Development -> USB debugging 
- Reboot your device into download mode: Turn the device off, then power it on again by pressing and holding VolumeDown + Home + Power simultaneously. You will know when you are in download mode, it is really obvious
- Start ODIN
- Connect the device to your computer using USB
- Wait a few seconds, the ODIN screen should show you that a device is now connected
- Make sure that in ODIN NOTHING is checked, except the “Auto reboot” and “F. Reset Time” checkboxes. Press the “PDA” button, and select the “XWKDD_insecure.tar” file.
- Press “Start”. ODIN you should now be flashing the kernel, and the device should reboot.
- Wait until the device is rebooted, and while still being connected over USB, start SuperOneClick, and press ROOT.
- Reboot the device
- Done!

Congratulations! You are done.

To confirm root access, you have two methods available: a new app should appear on your phone called Supersuser Whitelist which tells you have root access. Another way to find out if you have a rooted phone is to download any terminal emulator and enter su on it. A popup should appear asking for superuser permissions rights. When permission is granted, the $ sign should change to # confirming you have superuser rights.

The update came from Drew Garen (developer of the custom ROM). He had this to say:

ICS IS HERE AND IT’S GETTING BETTER EVERY SECOND…Enjoy Your Ice Cream Sandwich in two flavors from Drew Garen.

These roms are stable enough to use as daily drivers.

How to install Drew Garens Ice Cream Sandwich Alpha Built 2 for Nexus S:

First thing make sure you have a rooted phone. If you don’t have one, follow this article Root Nexus S to root your Nexus S. Second, make sure you have ClockworkMod Recovery installed. If you don’t have it, follow this article: Install ClockworkMod Recovery 4.0.0.2 (this article is for Samsung Galaxy S2, you must follow the same steps, except when you the program tells you to choose the phone model, select Nexus S).

Step 1

Download the custom ROM (which one you prefer) from Drew Garens website. On-screen buttons version comes with the on-screen buttons you see in Galaxy Nexus while the no-button version doesn’t.

Step 2

When the download is finished, copy it into your internal storage via USB cable.

Step 3

Now, turn off your device, and hold Volume Up + Power Button at the same time until the phone boots into ClockworkMod Recovery mode.

Step 4

Format /system, /data and /cache from mounts and storage in main menu of ClockworkMod Recovery. Next, make sure to wipe data/factory reset from main menu.

Step 5

Now, go back to main menu and: install zip from sdcard > choose zip from sdcard > [name of file you transferred to your Nexus S in Step 2].

Step 6

Select Reboot from the main menu. You are Done!

The rooting method was developed by clock workmod, which posted a picture with the Nexus S running custom ClockworkMod Recovery.

This is the guide he posted on xda-developers forums:

First, reboot into your bootloader/fastboot mode. (Volume + Power Up, or adb reboot bootloader)

fastboot oem unlock

Then, install this recovery:

http://koush.tandtgaming.com/recoveries/recovery-clockwork-herring.img

fastboot flash recovery recovery-clockwork-herring.img

Then boot into Clockwork recovery and install the Superuser zip file (adb reboot recovery, or from fastboot choose recovery):

http://forum.xda-developers.com/showthread.php?t=682828

To install a rooted/insecure boot image (adb has root):

http://koush.tandtgaming.com//samsung/herring/rootboot.img

fastboot flash boot rootboot.img

ROM Manager support is coming shortly.

If you decide to get it on your phone keep reading this article and you will find everything you need.

First you need to download these files:

GT-I9100_ClockworkMod-Recovery_4.0.0.2

Odin3-v1.85

Now, only a few more steps and you are done. These instructions are provided by the developer himself.

Power your device off. Boot into Download-Mode using Volume Down + Home + Power. Hit Volume. Up to accept the warning. Start Odin. Choose “GT-I9100_ClockworkMod-Recovery_X.X.X.X.tar” as PDA (no repartition). Connect your phone. Start flashing. After reboot you can easily root your device using SuperOneClick.

Instructions: Press Volume Up + Home + Power button to put your phone into Recovery Mode. Now use the volume keys to navigate and Power button to select.

If you are having problems, go to this article Root Samsung Galaxy S2, and a more detailed guide is in there. You can follow it, with one exception: use the ClockworkMod Recovery file downloaded here instead of the one available for download there.

If you would like to test the Alpha Build of the Ice Cream Sandwich, here are some facts you need to know first: data connection (3G) is missing, so it’s audio, USB mass storage and camera support. This version is for testing only and not for daily usage. Still it is fun to try.

The developer had this to say about it:

Installation:

• Please use at least 150MB system partition (and at least 2MB cache partition). (New version may need larger system partition.)
• Full Wipe.
• Flash the ROM.
• MAGLDR: Flash NexusHD2-IceCreamSandwich_Alpha1.zip, then reboot.
• cLK : Flash NexusHD2-IceCreamSandwich_Alpha1.zip andcLK_kernel_for_ICS.zip, then reboot.

The official version of Android 4.0 Ice Cream Sandwich came with the Galaxy Nexus. The new user interface makes Android look mature.
