Default soft brick phone flashing rom

I downloaded twrp and CM 10.1 CR2 for my MK2 4.3JB galaxy S4.

I made nandroids on the extra then went in used the wipe feature in twrp then loaded cm and gapps. Worked great and I love the ROM.

Went to put back nandroids. Used the wipe feature again then restored nandroid. Bootleg and stuck on the yellow sprint screen. Tried to flash Odin .tar and it started with a ton of FC then said something about data partition.

I had no choice but to factory wipe and I wanted to keep all my internal stuff. The stock to CM worked fine but just doing general wipe did not work to restore my nandroid.

The CM I noticed is 4.2.2. Is this an issue going back to stock 4.3 nandroid ?

I'm restoring the phone completely so it's fresh out of the box then rooting then using twrp to try to get back my old nandroid.


What did I do wrong in the process that caused it to stall on the yellow sprint screen ?

Now that I think about it I did probably a "dirty" flash since. I did not completely factory wipe the phone just the dalvik cache, cache and the last item on TWRP.

Once you go to 4.3...aka MJA or MK2 you cannot go backwards. So that may have been your issue. Try stayin with 4.3 or up

If you say "Please"... be sure and "Hit Thanks!!!"

OK I tried again after wiping, flashing 4.3, rooting, setting up TWRP.

I wiped everything and when I made my nandroids I checked ALL the boxes. I'm currently on CyanogenMod which works fine but I cant restore my nandroid. I wiped all then used restore from my SD card. I have twrp 2.6.3.0 I think.


I'm still getting stuck on the sprint screen. Help !

Don know about checking everything?? I make sure that SE Linux is checked (i use philz) and then save to SD. Have had zero issues so far and I bounce from 4.3 TW to 4.4 AOSP daily. Sorry I've never used TWRP so I cannot begin to help troubleshoot.

I just want to make sure you are not wiping before you create the nandroid backup. I reread your post and it was unclear. When creating the backup you should not wipe first. Next, when switching between AOSP and Touchwiz things can get tricky. Usually a failure to boot is after doing a nandroid is caused by the kernel not being correct for the rom installed. It would probably be best to keep an AOSP kernel and a Touchwiz Kernel on your sdcard so you can flash it after you restore the nandroid backup to ensure the proper kernel is in place.

Secondly, it was mentioned above that you can't go back to 4.2.2 after going 4.3. This is actually incorrect. You cannot flash a stock tar of an older 4.2.2 rom through odin if you have the MJA (AKA Knox bootloader). You can however flash a 4.2.2 rom using recovery since it does not attempt to change the bootloader.

I don't think I wiped before making the nandroid, but I'm not sure. I have the Sprint GS4, and the nandroid was a 4.3 (Dec 2013) firmware.

Can you help me out here, I'm really lost. Do I need to flash a Touchwiz kernel on top of the nandroid through TWRP (flashing multiple zips) ? Where do I get the kernel ?

Made a nandroid of my Cyanogen Mod. Wiped phone and restored Cyanogen Mod nandroid. No problem. Worked fine. Just the original that I made is not working.

There are a lot of people that have had problems switching between Cyanogen Mod and Touchwiz using nandroid restores. It usually is the Touchwiz kernel not being restored when restoring the backup. When you boot up, you won't get past the initial boot screen. If this happens, you should just have to reboot back in to recovery and flash a TW kernel then reboot or after your restore your nandroid backup, just flash the TW kernel before rebooting. Look in the Android Development section for a custom TW kernel or you can try this kernel that unkownforce posted from his Triforce rom: http://www.androidfilehost.com/?fid=23321874045862620
