I have been trying to revert to stock 4.4.2 software (the ROM had root) on my device. Previously it had an official CM13 nightly installed as well as the NE4 bootloader I recently flashed and all went well when using the custom ROM and TWRP 3.0.2. After I manual flash the 4.4.2 stock rooted rom, the screen seems to get stuck on the AT&T logo during first boot. What can I do? Does this have to do with switching from Marshmallow?
Did you perform a full system wipe before flashing? Did you perform a factory wipe after flashing stock?

I am running IOKP 4.3.1 on my nexus. I have downloaded the OTA update for kitkat 4.4. Can I flash the 4.4 update from cwm or so I have to return to stock then flash it? I ask this because my stock backup will not restore due to md5 mismatch. Thanks for any advice.
Anyone?
Just backup, restore a flash the 4.4 ROM.

OK I've backed up iokp. Can I now flash 4.4 from cwm? Or do I need to flash stoc first?

You can only flash an OTA if you are on stock ROM.
OK but how do I get back to stock ROM then? My backup won't restore.

If you don't know how to flash back to stock manually you are probably better off using one of the toolkits in the development forums.

Tasssadar has some stock flashable zips here:

Don't forget to thank him if you use it.
They seem to be stock kitkat. I would need to flash stock JB and then flash KK though, yeah?

No. Just wipe(cache, dalvik cache, data, and system) and then flash KK and you are done.
Another edit: Since you can't use a computer for this, you should download a few other ROMs so you have something else to flash if something goes wrong. I would really only recommend upgrading if you have access to a computer. Things can go wrong very easily. Good luck.
Thanks very much!
They aren't update custom ROMs, they're like factory images. You just need a kitkat 4.4 custom ROM that you can flash in custom recovery. If you don't have custom recovery on your tablet, you need to use your PC to flash it, or just boot temporarily.
Afterwards, restore your tablet, clear cache and dalvik cache, install zip, choose your custom rom, and flash it.
If there is an update for a ROM (such like nightlies for CM) you wouldn't have to restore the tablet, just flash the updated custom ROM because it's just an upgrade.

Hello everybody!
I have a question
Yesterday I have had many problems with my Note 10.1 (P600). I've had a custom ROM and had it rooted.
Today I decided to put back the original firmware from Samsung via Odin.
Can i do a factory reset now without any problems?
Hopefully someone can help me.
Thanks!

Sure, if you want to reflash factory firmware, just use Odin and flash. Make sure you backup all your stuff before factory reset or flash stock firmware. If you want root and install custom recovery, you could follow these instructions http://forum.xda-developers.com/gal...ersu-2-6-1-t3266010/post64198381#post64198381

Hey everyone. I'm having some troubles with every custom ROM I install on my S3 T-Mobile (d2tmo) so I want to come back to Stock ROM. I've been watching some tutorials, but lot of them are pretty old, and none is for the Galaxy S3.
So, what do I need to do to go back to Stock ROM?
Should I do a full wipe from recovery (TWRP) and then flash stock ROM via Odin?
The custom ROM I flashed is 6.0.1. The phone had 4.3 when I flashed the custom ROM.
Am I right about what I think I should do?
Thanks in advance. :good:
Yep. The firmware you'll use in Odin should be a .tar.md5 file.
Just flash the latest stock rom from sammobile.com using Odin. No need to do anything before flashing the stock ROM.
After flashing the stock ROM, immediately boot into recovery and perform a factory wipe.

Thank you very much for answering my questions guys! Everything turned out ok!
But I have a doubt about a little think that I hope you could help me.
Before flashing the stock rom I was planning on backing up my efs folder from the TWRP,version 2.8.70 for my s3 (d2tmo), but when I try to do a backup, there no "EFS Folder" option, however, on my other phone, a Galaxy Note 3 Exynos Variant (International Version) when I try to perform a backup there is a EFS folder option for backing up. It is also a TWRP recovery, and same version. 2.8.7.0. I know the phones are completely different, but, why if I'm using the same custom recovery and same version I can't do a EFS Folder backup from the backup option?
I hope I made myself clear about my question. Sorry for my English BTW, it is not my first language.
Thanks in advance!
Maybe this will help although it requires root: http://forum.xda-developers.com/s6-edge-plus/development/updating-t3210266
My M919 has MM on it. I want to unlock it. I downgrade the modem to MDL first.
It still working when MM using MDL modem.
Then I flash TMB-M919UVUFNB4-20140314115123 on it.
Now it's bootloop on the T-mobile screen.
My bootloader is FOK3 before I flash TMB-M919UVUFNB4-20140314115123.
Basically, I need it unlock and get my phone work.
please help.
Thank you.
EDIT, now I flash the M919UVUFOK3 and still bootloop.
I believe the phone must be running a stock rom before downgrading the modem.

when i flash the M919UVUFNB4 and M919UVUFOK3, i think it would downgrade my modem to FNB4 and FOK3 respectively.
Are you going to unlock via code or regionlockaway? Unlock code requires a stock Samsung dialler. Regionlockaway requires a stock Samsung rom running the old modem and root.
If it's bootlooping, perform a factory wipe using stock recovery before booting the stock rom for the first time.

unlock code need samsung dialer mean stock samsung rom, right?
anyway, when i tried to flash stock rom, it bootloop, I tried factory reset in Twrp. but it's not helping.
Wipe needs to be done with stock recovery.

could you tell me how?
so i flash the stock rom, then where do i look for stock recovery?
Flash stock rom then use the volume up and power to boot into recovery. Use the same method that is used to boot into twrp.
Hi, I'm currently using this method to flash roms, and I've flashed OctOS M a total of 3 times using this method, but for some reason, after a bit of time the ROM gets really buggy.
Is there a better way of flashing this ROM, or is it the ROM itself causing these issues.
Thanks,
Which phone do you have? For the i747 and i747m can be flashed with TWRP from Odin. The custom ROM and Gapps and then flashed from TWRP.

Currently have an i747m
its just that for some reason, at first OctOS M works perfect, and then starts to have tons of issues overtime, which other people dont seem to have.
I remember somebody telling me to wipe data and cache about 3 times before installing the ROM in TWRP, even tho i usually just do it once. Is that the proper way to do it?
Thanks,
The phone is running the latest KK bootloader and modem/baseband?
Did you use TWRP to wipe system as well before installing the custom ROM?

Not sure how i can check if im running the latest bootloader or modem/baseband.
Yea, I had also wiped system, and delvik cache.
You can install the Samsung Phone Info App from the play store which will tell you the bootloader and modem/baseband version in the phone. I think FOB3 is the latest.

My bootloader and modem/baseband end in FOB3.
Okay, then that's not causing the problem. It may be a bug that's unique to your particular phone. The only way to tell for sure may be to install a different ROM to see what happens.
