OK. We have had a major breakthrough on the SGH-S959G. TWRP (from Omni). It's compatible with Cooked, Omni, and RenderBroken's CM11 ROM. No more different recoveries for different ROMs. I think this should be on every SGH-S959G for now to avoid any more issues with Android 4.4.

Can this recovery be used for 4.3 as well, or is this strictly for 4.4 roms? If this is for CM11 only, are there any TWRP versions that work properly on the device instead of CWM?

when flashing do you have to reflash everything or can you just flash the recovery then reboot recovery then reboot or after new recovery reflash the rom and gapps

I kept getting errors on TWRP. Would not let me update the ROM. Couldn't read the whole screen (text appeared to be cut off), but it looked like a build.prop error. Back on CWM 6.0.4.5 for now.

Was trying to flash CM10.2 nightly for i777.

Edit: Appear to be getting the same error on CWM 6.0.4.5 now. Status 7. Ideas anyone?

Try using the AJK recovery zip. That's going to be the philz cwm 6.0.2.7 further down in the op

Sent from my SGH-S959G

Going to try that shortly if my current attempt doesn't work. I'm trying to stick with TWRP, because I like it much better. I got rid of the getprop line from the updater-script file - hopefully that does the trick. Putting the files on the SD card now.

What are you running in the background to have that kind of battery life? I don't even think mine would drain that fast with a battery drain app! Kinda sounds like you may have a bad battery.

Also rooting messed up my airplane mode. It likes to turn its self on, a lot.

Did you install the hiemdall drivers first, and was the phone in download mode?

Yes straight talk will probably replace it for you. I believe they have a 1 year warranty.

How in the world do you update CM from inside TWRP? I can't find the CMUPDATE folder.

(edit: nevermind. For some reason, I had to boot into Android itself and then back into the recovery after flashing before it would show what was on the internal SD card partition)

(edit 2: and then it failed anyway.)

(edit 3: I'll just stick with CWM. To each their own I guess :p)

(edit 4: Okay, so it appears I can't update CM unless I use CWM 6.0.4.4. CWM6.0.4.5 and TWRP throw a weird build prop error that I'm too lazy to try and figure out, so 6.0.4.4 it is.)

Yeah i was having some issues last night with my SD card. I made a backup with online nandroid backup and saved to external SD but my restore menu only shows those on the internal and i can't find a way to make it look on the external SD for a backup.
For now I'm going to continue to tinker with it but I'm not going to try any experimental stuff I'm not sure how to fix.

What i LOVE about this phone is that as long as i can get into recovery, i can always get back where i was :thumbup::D

    THIS IS ONLY FOR THE STRAIGHT TALK S2 MODEL# SGH-S959G...... NOT COMPATIBLE WITH ANY OTHER PHONE.

    THE BEST WAY TO ROOT / OR FLASH A CUSTOM ROM -
    Install RECOVERY using ODIN, make a BACKUP, then flash the ROOT ZIP in RECOVERY.
    - TWRP 2.7.1.0 Odin-
    - Make a backup with TWRP before going any further. Boot into recovery, select backup/ restore, backup.
    - Root Zip- flash zip through CWM thanks to cynnar-

    - PhilZ CWM v6.0.2.7 If you will be using a Siyah based kernel ( AJK Kernel ), or would like the extra options in CWM flash this- View attachment 1703135

    If you prefer CWM flashable zips can be found further down, and throughout the thread (search).


    - ROMs
    - I777 Main Thread- http://xdaforums.com/forumdisplay.php?f=1301 (Android Development, and Ported Development to find ROMs)
    - OR flash CyanogenMod 10.1 from link below (this is flashed in CWM) From CyanogenMod 10.1 all i777 custom ROMs are compatible.
    - CyanogenMod, and most all custom ROMs are already rooted when you flash them, no need to root first.
    - You may need to change your APN for data to work with some custom ROMs. Stock APN is at the bottom of this post. Usually you can just edit the included APN from att.mvno to wap.tracfone , and save it, then select it. If data still doesn't work delete all other APNs besides the one you're using.

You should get a green PASS message in the top box.

    - Save Zip file to be flashed to the Root (not in a folder) of your External SD card
    - BOOT INTO RECOVERY- Phone off

    REMOVING THE YELLOW TRIANGLE

    GINGERBREAD ONLY! (Root Required)
    - Extract the stock zImage from the factory firmware at the top of this page (I used 7zip, and needed to extract it twice to get it apart).
    - Put the stock zImage on the root (not in a folder) of your internal SD card. You can do this through the usb, adb push (adb push- Copy and paste the zImage into your folder with adb, connect your phone with usb, then command- adb push zImage /sdcard/zImage), whatever method you like.
    - Now using adb shell, or terminal emulator found in the market (if you don't' have adb ask GOOGLE) issue the command (capitilazation and spacing matter):

    $ adb shell
    $ su
    # dd if=/sdcard/zImage of=/dev/block/mmcblk0p5

    This must be done as #, if you have a $ enter command: su
    You must already be rooted for this to work. To switch to a different kernel afterwards you can use the same method, or CWM without getting the yellow triangle again or increasing the flash counter. As long as you flash internally, if you use Odin or Heimdall to flash anything thats not stock it will come back.


    REMOVING YELLOW TRIANGLE ICS AND ABOVE!
    -If running ICS or above you can use triangle away found here- http://xdaforums.com/showthread.php?p=22462960

    Let me know if this link gets killed and I'll add it to Dev host.

    Flashing other versions of CWM with adb (Root Required)
    - Extract the zImage (boot.img) from the ROM of your choice (I use 7zip to extract it).
    - Put the zImage (boot.img) on the root (not in a folder) of your internal SD card. You can do this through the usb, adb push (adb push- Copy and paste the zImage into your folder with adb, connect your phone with usb, then command- adb push zImage /sdcard/zImage), whatever method you like.
    - Now using adb shell (if you don't' have adb ask GOOGLE) issue the command (capitilazation and spacing matter):


    $ adb shell
    $ su
    # dd if=/sdcard/zImage of=/dev/block/mmcblk0p6

    or if it's a boot.img

    # dd if=/sdcard/boot.img of=/dev/block/mmcblk0p6

    If you don't have service after unlocking and switching SIM cards you need to flash an at&t modem like I777UCLL6 found above. Apparently the modem used by Straight Talk only works with their service.

    The op needs to be updated with this'd information...

    The latest cwm is only for kitkat ROMs, that's cm 11+. Of you want to go with jelly bean ROMs like the one you're trying to use, you need to use cwm 6.0.2.7 it's older but JB won't flash on the newer ones. There are a few different versions but any will work as long add it's philZ, AJK, or 6.0.2.7

    Since you already have cwm installed you can just DL the zips and flash them in recovery then reboot "recovery" and it will be complete. No need for Odin now. Try that and get back to us

    I think I'm just going to replace CWM with the new TWRP in the op. It seems to be easy more compatible. Plus I like it better.

    EDIT: Done. Op updated to install TWRP with Odin to be more compatible.

    Sent from my SGH-S959G

    since this post is in AT&T Samsung Galaxy S II SGH-I777 section...i thought it might be compatible. i even saw a lot of ROM posts where they says its compatible with i777 and sgh s959g....so i was in doubt and had to ask.....glad to know its not compatible...thx....







    I thought it was...a lot of the ROMs I search are based on the i777 builds just have to make sure you have the correct radio installed.....I've rooted mine and used several different ROMs just based off of this thread. Searching the thread with the search tool will yield massive results. See post#5 from the OP that's a fairly good clue.

    Ok ok ok wait... Let's clear up some confusion. The one and only difference between the 959g and the i777 is that the 959g has its recovery on a separate partition by itself, whereas the i777 has kernel and recovery on the same partition. The 959g can use any ROM or kernel built for the i777 no problem. But if you want a different recovery on 959g you must use one of the zips from the op or Odin. If you had an i777 and you flash a new kernel it will also install a new recovery as it will be packaged in the zip. If you flash the same kernel on the 959g, your kernel will change but recovery remains untouched since it is on a different partition. That is the one and only difference between the two. Happy flashing :thumbup::D
