Hello guys! the instructions are very easy if you do the steps correctly.
This is my first post in the development section.

First, go to market and download OTA Rootkeeper

Second, open the app, Select Create SU Backup.

Third, Select Temp UnRoot(with backup)

Fourth, uninstall Superuser, if you have superuser elite uninstall it also! and uninstall OTA Rootkeeper(dont worry it will not delete UR Backup!)

Fifth, Download and install the OTA.

After it is done and reboot, do a power cycle.

and the last step, go to market, install superuser and ota rootkeeper.

Launch OTA Rootkeeper and Select RestoreRoot, accept the superuser permission, and reboot!

AND ur back with rooted 2.3.6!

Michael


Alternate method! This is Jim's method(Thanks jim for this other way)

To do the 4ever root hack do the following:

1) open root explorer or ew file manager etc...

go to /system/bin

find the file named mount_ext3.sh
touch and hold the file name until the menu appears, go to open in text editor.

Add the following line to the VERY bottom of the file, after the fi

chmod 4755 /system/bin/su
chmod 4755 /system/xbin/su
chmod 644 /system/app/Superuser.apk

2) SAVE!!!! the file.
3) Do the OTA update.
4) You should still have root after the update, now.

Jim

Enjoy, Hope this helps!

Does this work if coming from SuperCharged V4, or only if coming from stock 2.3.5?

Thanks

The easier way to do this, is just do the 4ever root that was done for the bionic.

Just add these lines to the bottom of the /system/bin/mount_ext3.sh files with the text editor in root explorer, or through adb.

chmod 4755 /system/bin/su
chmod 644 /system/app/Superuser.apk

Do that BEFORE the OTA update, and you will not have any issues with OTAs ever again and loosing root. but if you did not do the update maually, and you used the one-click you might need to add the following line as well....

chmod 4755 /system/xbin/su

I just used OTA Rootkeeper normally and it worked fine for me. Backed up root, temp un-rooted, downloaded and applied the update, then restored root from OTA Rootkeeper after the update finished. I have root back just fine...

Did this not work for others?

be carefull, the update brings a new security environment and new security patches that google just released. the update over writes parts of the system data. the safest way that i tested is this method. be careful with ever root

Jim,

I have a question about running a Deodexed rom. Will I have a problem upgrading or do I have to SBF back to stock? I also have the 1 percent mod that I love. How can I keep this. My understanding is this only works for deodexed roms.

x2 I used this method and it works fine. No messing around with OTA rootkepper, no need to uninstall superuser/etc.

ever root is arguably SAFER than your method. All it does is make the system change the permission on the files on every bootup. It's not rocket science.

I'm not Jim but I do have the answers to your questions! ;)

You should flash the fkz's (sbf) files before you update, just a good idea to remove any oddities or potential problems. :) Also most modifications do relay on a deodexed ROM , so my guess is that it won't work with the new update yet. My personal recommendation would be to wait until lfaber06 incorperates this update into a nice little cwm flashable zip (around this weekend, or next), that will already contain root, as well as the 1 percent mod and the updated theming!

well that's what i get for not reading here first. My coworker was demo-ing an app to our CEO and the update notification came in. A few minutes later he comes back and says he hit download then install when it came up. When i got it it was flashing in recovery already :(
