[Q] Phone stuck at ATT logo after OTA update

I updated my phone to kitkat using the OTA update while rooted, which was definitely a stupid thing to do, but now my phone seems to be stuck on the ATT splash screen after booting. It's been this way for 15+ minutes. Any way to reset it/unbrick it?
I am able to get into recovery mode and download mode.

Try a factory reset in recovery?

I tried this and nothing changed. Would a flash back to 4.3 stock fix the problem?

I would read about doing that before doing so. From what I've been reading if you're on a certain bootloader, you can't go backwards. I'm by no means an expert, so just read a lot so you're comfortable with doing that. Good luck .

Dont flash old firmware, but older roms are ok to try. I'd start by trying to flash enewmans stock kk rom.

I managed to get the phone back to 4.3 Stock however now I don't have mobile data. I'm thinking this is a modem issue? Anyone have a fix?

I believe dochliday77 has a post somewhere with the kk modem ripped from the rom

I installed a 4.3 modem and it did not fix the issue. In phone status IMEI is Unknown.

You need to install the 4.4 modem on a 4.3 rom

Thanks! I coincidentally figured this out right before checking this post. For anyone having the same issue, check this thread here. It seemed to fix my issues with mobile data, wifi, and pretty much everything else.

Hey im also stuck on the at&t logo. I was rooted but used triangle away to remove the counter and unrooted via super su/user <--- I don't really know the name of it. So i did the ota update and the phone restarted, it installed the update and restarted again and now will not get passed the att logo, even let it stay on over night. How did you get back to 4.3?? I'm a serious n00b so I need detailed instructions, anyone please?!?

Everything in download mode needs to say "official" in order to get the OTA. See if this helps:
http://forum.xda-developers.com/galaxy-s3-att/general/how-to-restore-device-status-to-t2832880

If the ota appeared to flash, and its hanging during boot, factory reset should solve it.
Be aware that doing so with stock recovery installed will wipe the internal sd card.

For me, the only that worked:
- once rooted, make sure you get both current status and version (to be checked in download mode) as OFFICIAL (you can use Xposed or similar to do this, different threads can be found on this)
- flash with stock recovery
Hope this can help you as well...

In Xposed I found system status under "Security Hacks" but couldn't find where to change version? Would you please let me know?

You should try to go over specific Mode / Module (not sure about the English translation). To do this:
- Install Xposed Installer (or similar mode xposed mode installer)
- In Xposed Installer, download the mode "Cosmetics Device Status Normal Modification"
- Then, in the mode menu, select ComesticSysScopeNormalizer (or something that looks like this...) to activate
Restart, flash stock recovery, boot in recovery mode... and cross fingers!
Hope this will work
Best,

Sorry if this is too simple, just afraid of the bricking with Knox, etc. Which Stock Recovery do I use with KitKat after rooting?
Thanks!

not a rooted device
My tablet isn't rooted & I don't want to root it because it will violate my warranty so is there any other way to get the screen mirroring to work without rooting my device?

Normally it should work until you flash a custom recovery. But in this case you already set the knox flag. So, it doesn't matter if you are also rooted or not.
For whom it not worked:
After flashing the stock recovery boot once into recovery mode. For some this helps.

Mine's stock unrooted and i get that error too.

Secure boot error means that your kernel didnt pass system checks?
What rom are you trying to flash and what firmware version are you currently on?

I'm not sure what my firmware is but I'm running google 5.0 lollipop and Im trying to install cm 12.1

Writing again because im still having the same problem. I tried rooting again and installing a new kernel the 777 kernel for d855 and im still getting the secure boot error, anyone else ever have this problem i feel like ive tried everything

If you rooted from 5.0(Not restored to Kitkat then root then flash to Lollipop), You need to install Kitkat Bootloader and aboot as they fixed the issue in Lollipops bootloader.

try Auto Rec from playstore to solve your problem of "ecure boot error" on rooted Lg G3 D855 international

You need the Kitkat Bootloader, you need to flash Kitkat via LG Flashtool then enjoy custom roms

OK Guys so i figured out my problem, it seems to be that if you install multirom it completely messes up your recovery. All i did was install AutoRec again and it was good to go! Hopefully this helps anyone else with similar problems

Crashing boot looping lines colours bad bad bad tablet

I have a tab s 8.4 sm t705 I was running kk rom I flashed LP rom and now it boot loops. The images I have attached is when it crashes and reboots. For some reason it is showing all lines and either blue or red screen sometimes.
I tried to flash twrp and it will not do it. I am at my wits end what to do any help would be a saviour
Cheers

update i was able to get twrp flashed but now when i try to flash a rom i get cannot mount system?????????????????????????

It looks like you flashed a ROM for the t805 not the t705.
First let's get you back to stock.
Download the firmware for your device from the link below.
Follow the instructions to install it. This will get you up and running again.

Hi ya, I have already done that but issue still there. Now I can boot up and start the setup process and the tablet freezes and reboots about 1 minute into setup process near where you have to sign in to google
Any more suggestions:crying::crying::crying: please

Tbh I think you have a hardware issue.

Now new problem when I try to install twrp it will not do it, If I go into the system recovery and try to do factory reset an error shows as follows
E: unknown volume for path {/sbfs}
E: unknown volume "/sbfs"[/U][/U]
Data wipe complete.
I thought it may be battery related but I have changed to a genuine new battery. still same issue

Did you root your phone? If you did, you can use Qfil to restore your stock boot img (if you made a backup). If you didn't, you'd have to get someone to send you their boot image. I would have sent mine, but I cross flashed from Sprint to Open US. I doubt mine would work for you.
Why can't you cross flash?

You should clear modem and some other files stated in that post. Then you select all partitions in LGUP except one file also stated in the post. (I can't remember the name of the file)

From my research, i think a file called fsg has something to do with sim working. Also my IMEI is 0. any suggestions would be highly appreciated.
