[Q] Updating to Newer Version of Cwm on Tmobile T879

The updated cwm is on the cwm web site, but it is in img format, which means you have to use adb on the command line to overwite your current recovery with the new one.

I took a flashable zip from another phone and replaced the img file inside with the tmobile one and that is what I use. Here it is if you want to use it: https://drive.google.com/file/d/0Bx_IbXnhPXBJRlFxR0VlSXVhRTQ/edit?usp=sharing

Make sure you know and pay attention to what you are doing, screwing up the recovery will be a bad day.

Jellybean roms use TWRP recovery. http://teamw.in/project/twrp2/113

Some have had better luck with 2.5.0.0, but the latest version should work also.

You need to have a copy of twrp and a copy of cwm on your sdcard so that you can go back and forth between jellybean and kitkat, if that is what you want.

Do your system wipe/factory reset in the recovery that you will use to flash. So going to Kitkat, first reboot into recovery, do a full backup of everything, then flash the cwm zip, then reboot into cwm recovery, then do factory reset, then flash your rom zip, then flash THE CORRECT GAPPS, then you can reboot.

Going back, same thing. Recovery, backup, flash twrp, reboot, recover your backup.

Gapps are important, there are 2 different jellybean gapps one for 4.3 and one for 4.4 Kitkat, be sure you flash the right ones or, you will just get an error, or you will get errors when starting up, either way it won't work. http://wiki.rootzwiki.com/Google_Apps

This thread is where you get the 4.4 Kitkat gapps, full package is fine, just be sure it is the 4.4 one. http://xdaforums.com/showthread.php?t=2397942


Read the ATT forum also as the device is the same, but don't flash ATT roms unless you are using the patch. http://xdaforums.com/showthread.php?t=2573315

Lot to read and understand and lots of files to get on your sdcard before you proceed. Good luck.

I can tell your post will be a super helpful resource, thank you for that.

are these my options, basically I can either override cwm with an adb command or flash the rom you shared above? I'm just a little unclear on that?

Yes. Here is the clockworkmod download page. Scroll down for the tmobile note: http://www.clockworkmod.com/rommanager

Look in the "recovery" column, click on the one for tmobile and you get a recovery.img file.

To get the adb instructions to install it, you have to go to the TWRP page for this device: http://teamw.in/project/twrp2/113

"You can use adb or terminal emulator to install the following image:
adb push openrecovery-twrp-2.3.1.1-sgh-879.img /sdcard

adb shell dd if=/sdcard/openrecovery-twrp-2.5.x.x of=/dev/block/mmcblk0p22"​

So you can do the same thing with the recovery.img from the clockworkmod page.


Now download the zip I gave you, verify that the recovery.img inside is the same as the one on the clockworkmod page. Do an md5 on it to check, pretty sure its the same version. Check the updater script, it is the same command as above. Also, I believe the original post in the "patch" thread that I linked you to has a flashable zip file for clockworkmod as well.

Either of the zips you just flash in your current recovery. Much easier and less room for making a really unfortunate mistake.

Of course the adb stuff is not the best way to go about it. Just use the flashable zip. Or install goo manager and allow it to install it. Check the twrp link that I gave to you. Instructions are there. I can upload a twrp zip a little later.
