I am currently on rooted marshmallow and want to return back to kitkat. I was able to unlock my bootloader successfully then had flashed the magisk rooted MM stock rom. I'm having an issue with a Sim card error notification after awhile then my verizon service gets disrupted. The only way to get my service back is to re-flash the MM rom. Also the external sd card cant be formated as internal storage therefore i'm not able to do my regular backups in twrp. The system font size is too small as well! I've researched this problem for an entire day and asked about the MM rom issue in the following forum where I got the rom from and unlocked my bootloader.

I've tried to flash in odin the following file ALL_VZW_G900VVRU1ANCG_G900VVZW1ANCG_964333_REV00_user_low_ship_MULTI_CERT.tar file but it failed! When I was on kitkat it worked if I had to return to stock.
Right now I'm downloading VZW-G900VVRU1ANCG-20140410100641 file in hopes i'll be able to return back to kitkat. Is this not possible?
All help is greatly appreciated! Thanks!

HI all. Bought myself a UK G2 the other day, came with 4.4.2 installed. I followed to guide to downgrade it to 4.2.2 (i'd rather keep it on that). After the .kdz flash (yes, it's the correct region and for the 16gb) it just says "no sim" all the time. Rooted, installed twrp, flashed the rootable kitkat zip that's in the forum, still no sim now I'm back on 4.4.2. Any ideas anyone? I need my phone for work so need it sorted asap.

Make a factory hard reset
Nope, still no good. Flashed both the official 4.4.2 kdz and also the 4.2.2
I'm having this same problem. I really need this fixed. I used this method to get root and now I have no service. It is very important that I get my phone working!
Edit: After several formats I tried a FULL format including Internal and System partitions then put the phone in Download mode and followed METHOD 2 of this guide.
Hi, I have a N910F in the UK. I was on stock BOC5 rom loaded via OTA. I then rooted via cf root and loaded twrp all succesfully. I took a back up and stored on external sd card and internal. I then saw stock BOC5 deodex so thought i would try. Downloaded the file and it failed to flash. I then used my ext SD backup and that failed, so flashed internal, all was good.
Then the crap hit the fan. I then thought if I went official BOD2 from sammobile then flash the deodex maybe better. Downloaded BOD2 and went through odin, it failed saying the file was too large. i then did a search and found a Pit file, so used that in odin too and failed at the same. went to recovery, it booted into download mode saying to connect to kies. Tried that and my comp didn't recognise phone. Reflashed cf root and twrp, all worked but can only see ext SD. internal says 0mb. i get boot with both samsung logos but then says decrypt and to reset phone. i have since downloaded a couple of sammobile roms and a couple of roms flashable in twrp and no luck.
anyone have any ideas or suggestions? I know this is probably back to samsung repair.
quick update. downloaded newest version of odin< downloaded 3mobile uk version and went through odin with this pit file http://forum.xda-developers.com/attachment.php?attachmentid=3135354&d=1422307712. this worked, rooted, installed trwp, installed my ext sd back up and all worked fine.
Ok, another update, I have lost efs. i used kies to go back to stock rom and used my twrp back up to restore efs. it passed in 1 sec but nothing in the efs folders.
i do however, have correct imei, connect to wifi, etc it does however have the wrong serial number showing. does anyone know why twrp isnt restoring EFS?

Hey folks. I'm finding a lot of threads from 2 years ago and unfortunately they aren't much help with my device. I've inherited this phone, and my goal is to upgrade to CM12. Unfortunately I'm dealing with AT&T's locked bootloader and other issues.
I'm currently on Android 4.4.4, Baseband I337UCUFNJ4. I've managed to get root access using the Odin method of flashing NC1 then back to NJ4, root is working., but I've been unable to flash an updated Recovery. I've tried everything except for the Safestrap method, which last I read wouldn't work for installing Cyanogenmod. Using Odin, I've tried to flash CWM Recovery after converting the .img to a .tar.md5 (Odin failed to transfer this), I've tried using ROM Manager to install Recovery (claimed to work, but actually did nothing), then also used Flashify and Rashr to flash, which seemed to get further, but upon reboot the phone gave an error about software not authorized by AT&T.
I've done way too much googling this weekend and trying all sorts of things that haven't worked, from all sorts of threads from 2013 and 2014, does anyone have a reliable method that works if I'm already on 4.4.4, or am I still out of luck with this device? There is no SIM in the phone right now, but I may want to use it as a phone later if I can upgrade to CM12.
You're pretty much stuck. Only ROMs you can flash are AT&T official stock ROMs for the S4, or ROMs that are specifically safestrap-compatible. No other recovery will work, either.
That being said, if you're interested in lollipop, there's a stock, deodexed lollipop ROM for our phone that is safestrap-compatible on here called Goldeneye v53 that I enjoy.

I'm in the same situation as you, I ended up using safestrap with Pure Nexus http://forum.xda-developers.com/galaxy-s4-att/development/rom-google-edition-s4-t2837239
Closest I could get to a desirable phone without original Samsung FW. Good luck
Hmmm. What I'm wondering at this point is how does the bootloader get onto the device originally? Can't a working bootloader from another model S4 be flashed in place of the AT&T one?
I would imagine that there must be some software that can be used to fully wipe the phone, repartition the memory, write a new bootloader, etc. If a phone were hard bricked, it would seem that there would be a way that Samsung or some carrier can use to get the phone working again.
I have downloaded a file for flashing stock firmware from telus with july updates, it contains several files. I have rooted and installed xposed on my stock firmware and I want to get rid of the installed system root and xposed flashes. The only way I can figure is to flash a stock rom back. What do I flash to do this? AP/CSC? seeing as this rom is an update as well I imagine I will have to flash bootloader too. Any advice or general walkthroughs or links would be greatly appreciated.
anyone?
in case anyone finds this I was able to flash and YES it flashes the boot.img and recovery.img but not csc or home. Which I dont really mind at all. When flashing over previous stock rom it upgraded the rom and all my stuff and cleaned out the system too! encryption is back and i can lock the phone, rooted it and was able to still have lock and encryption
Hi guys,
so flashed a stock note 3 rom for EE in the UK to remove the effects of the root and custom rom I had.
Flashed via odin, all went ok.
Went to update OTA to more recent version and it says system has been modified. Sure enough under settings/about device/status it says "custom"
my question is, is there a way to change that to official so i can receive OTA updates?
ive googled and seen a few solutions that didn't work.
I tried removing SD card, reboot and wipe cache - didnt work.
Also tried using xposed, tells me im not rooted so cant do anything
Finally tried SuperSU unroot option, told me again, not rooted.
Any help please!!
