[Fix] 4.3 ROMs stuck on splash screen after first reboot

For those of you who keep getting stuck on the splash screen after trying to restart your phone after installing a 4.3 ROM.
My steps were (and I take no credit for this, I can't remember who had said to do this and I wasn't logged in so I couldn't click the thank you button):
*Note* If you were already on the Stock 4.3 ROM you do not want to flash the 4.0.4, 4.1.1 or 4.1.2 Stock ROM since you will brick your phone. The Stock ROM contains the Bootloader which should never be downgraded. Fyi: the Bootloader is not the Baseband, the Baseband is just what Modem you're using.
1. Use Odin to flash the latest stock ROM
2. Enter the stock recovery and do a factory reset and clear the cache (I did both twice just to make sure)
3. Use Odin to flash the stock rooted ROM.
4. Enter the stock recovery and do a factory reset and clear the cache. (This might not be necessary but I did anyways just to make sure)
5. Use Odin to flash a custom recovery (TWRP 2.6.0.0 was the newest recovery when I did this last week)
6. Enter the custom recovery and wipe everything, then flash whatever 4.3 based ROM and then flash GApps if you want.
*Note* It seemed like the phone was hanging on the splash screen after either the initial boot or the first restart (I can't remember which, it's been a week) but it did boot and reboot fine.
I hope this helps out some people since I found it to be quite irritating that I could install a 4.3 ROM and set everything up but when I went to restart it would hang at the splash screen (going into the recovery and clearing the cache/dalvik cache wasn't helping).

Are you basically saying to revert back to stock settings and redo the entire root process again?

Yeah, from what I had read that seemed to be necessary since I had used Odin to update the bootloader (MF1 since my phone is the M variant) by itself when the newest Stock ROM had come out a while ago. I still flashed the newest Stock ROM (same MF1 bootloader for the M variant) but the first time I did it I forgot to enter the Stock Recovery to do a Factory Reset and Clear the Cache and ended up stuck on the splash screen of a 4.3 ROM after flashing a custom recovery. So I needed to reflash back to stock and start over.
Going into the Stock Recovery and doing a Factory Reset and Clearing Cache is necessary and doesn't take much time at all so you may as well do it just to be sure. I also recommend backing up your IMEI if you haven't done it yet.

This seems to have done the job. Running PAC 4.3 right now. I've rebooted successfully once so far.

Exactly what I ended up doing after nothing else was working. After getting it hanging the first time, even flashing 4.2 roms was giving me boot issues. After reverting back to stock and reflashing I'm now running the 9/1 Pac nightly and the 8/31 kt747 kernel.
I'm probably 10+ reboots in without issue and I flashed the kernel separately!

I'm glad to hear that this seems to be the proper fix. That's odd that you were having trouble with 4.2 ROMs, but then again I'd been running 4.2 ROMs on my phone since they first started rolling out. It's kind of annoying that everyone's S3 seems to be slightly different then the next.

Yeah this was a weird one all right. Just glad this post had a solution

glad i found this otherwise my first noob post would have truly been a noob move. Thanks wouldn't have guessed that fix for a few days at least.
verified it works. but it did require some weird time dealing with a bootloop issue on stock recoveries. had to find a .tar version of CWM to flash via odin for the final result.

Still Stuck at Splash Screen after trying to upgrade to 4.3
Background:
I had been running task's rom since 4.1.x. Upgraded to 4.2 with not problems and I kept the rom current. Tried to upgrade to 4.3 and that is where the problems started. It appeared to work, saw that Google was updating a number of apps but then then I kept getting error messages regarding various about various processes stopping unexpectedly. Rebooted the phone and it came up with Task's kernel splash screen where it remains frozen.
I can get into TWRP (v2.3.3.1) recovery and into Download mode.
I have tried wiping Cache and Dalvik Cache
I have wiped System
I have done a Factory Reset
I have Formatted Data
I have used Odin twice to get back to stock (I747UCDLK3) and both times it says "passed."
When I try to reboot it, however, it comes back to Task's Kernel splash screen (I do not see the Samsung screen)
Any help or suggestions would be great.
UPDATED: Found an older update from April and was able to restore it. Still wondering why 4.3 wouldn't take.

This Works
I was skeptical, but this actually works! Now running Task's 4.3 on my bell i747m without any problems!
Thanks for the tip OP :good:

If this works you're a life saver! I've been posting around 4.3 threads about this for weeks and no one came up with a decent answer....
Tried reflashing stock with root but didn't work... i'll try your way, see if that works
Gonna try this tonight!!!
Thanks!

I posted in the CM thread about this, but thought I would pass it along.. I didn't have to go back to stock non-rooted. What I did:
I odin'd Mr. Robinson's LK3 rooted
Factory reset from the 3e recovery
Rebooted
Odin'd twrp
Restored nandroid of CM
Good to go.

Solved
Thanks, also works for i727 skyrocket

If you were already on the Stock 4.3 ROM you do not want to flash the 4.0.4, 4.1.1 or 4.1.2 Stock ROM since you will brick your phone.
I'll add a note to the OP about not attempting to downgrade to an older Stock ROM though.

When I had done this back in August, I flashed the Rogers 4.1.2 Stock ROM since that was the latest stock firmware at the time and I have a Canadian S3.
If you had already flashed or been on the Stock AT&T 4.3 ROM, I'd recommend reflashing the latest Stock AT&T 4.3 ROM and following the instructions in the OP. Just make sure that you don't attempt to flash an older version of the Stock ROM that you were already on since you will brick your phone. The Stock ROM contains the bootloader and that cannot be downgraded. I don't have an American S3 since I'm Canadian so I don't know which 4.3 bootloader is the newest although I'm sure a quick search would answer that for you.

There is no latest Stock AT&T 4.3 ROM right now to reflash if you're already on the Stock AT&T 4.3 ROM. We cannot keep telling people this. If so, tell us how, because no one has, as of yet.
I've seen entirely too many posts telling people who are having trouble or phone is soft bricked on the Stock AT&T 4.3 ROM to flash or Odin back to stock. Then when asked how, the discussion ends.
That's also one of the reasons why I refuse to upgrade to 4.3 right now. At least I can still Odin back to stock as an option if something does goes wrong, but who am I to tell anyone to stay away from the latest toy, I mean update?

I'm sorry that I'm unable to help. As I had mentioned I have a Canadian Rogers phone (since I'm in Canada) so I don't know what's going on with the AT&T Stock 4.3 ROMs other then the fact that lots of people are having problems.
If you never flashed or did an OTA update to 4.3 then I'd suggest flashing the Stock 4.1.2 ROM. That or try what Ozark_8125 did since it saves you a couple steps (just make sure that LK3 isn't an older ROM than the one you were on).
If you're unsure what bootloader is currently on your phone and your phone is rooted I'd highly recommend downloading one of the many Root Check apps from the Play Store to verify which bootloader you're currently on.
*Note* I don't know which bootloader is for the 4.1.2 AT&T ROM nor do I know which bootloader came with the 4.3 ROMs. I'm sure a simple search would answer that for you.

[Q] Sprint GS3 - Unroot to stock 4.3?

So a couple of days ago I got a GS3 running the OTA stock 4.3. I wasn't sure if I wanted to use it because I find Touch Wiz kind of clunky. So I decided I would try out Cyanogenmod. I installed it via their new handy installer (as the sprint GS3 is one of the compatible devices). All went well and I got Cyanogenmod 10.2 running smoothly. Now I want to activate the device, but apparently you can't activate a rooted device on sprint. So now i need to get it back to stock 4.3 and I can only seem to find solutions to his problem for devices that have not gotten the 4.3 OTA update and are still running 4.1.2. On the Cyanogenmod installer guide says:
You may perform a full backup from recovery, after flashing recovery (you will have to do this manually, at the moment) and then copy it off the device, if you don't have an external sdcard. If you've already run the installer, you will have to find stock images and flash them using fastboot or Odin.

My problem Is I can't locate any stock 4.3 images with which to try this. If I can get my hands on a stock 4.3 image, would the process be just going into the bootloader and using Odin to flash the 4.3 image?
Can anyone help me out?

You only need to be on a stock tw rom, even if you are rooted it should activate. There are a couple in the development section.

I see, do you know of any any good 4.3 based tw roms? All the ones I'm finding are based on 4.1. Also, do I need to do anything special to flash from Cyanogenmod 10.2 to a touchwiz rom (as Cyanogenmod is AOSP)? I already have ClockworkMod recovery installed.

Nothing special, flash like anything else

[STOCK ROM] Stock 4.3 MK3 ROM [ROOTED/UNROOTED]

Can you ODIN flash to 4.3 from AOSP 4.4.2?

I flashed an AOSP 4.4.2 ROM a few weeks back, and I'm having a lot of issues with it. I would like to go back down to 4.3, but the backup I made doesn't work anymore. Would it be safe to ODIN flash a 4.3 image onto this device? If it is ,I should be able to use that to restore my backup afterwards, correct?

Just flash the 4.3 stock rooted image from ZenArcade...
It's bone stock except for root...and it does not contain the knox bootloader...
Wipe device and flash in recovery....done....g

If you flash back to stock 4.3 doesn't mean it's going to fix your back-up you perilously made. If the back up is failing then it's probably corrupted somehow...
Backups (nandroid) are usually done thru TWRP or CWM recovery if that's what your referring too...

[Q] Stuck On ATT Logo with I747 running official 4.4.2

I was running official 4.4.2 firmware. I was trying to add a custom ROM to my phone. I flashed the most recent Trwp on to the phone then did a full wipe. When I went to flash the rom it says failed. So I try to restore back to stock with the backup I made before I flashed the rom and now my phone will not boot up.. It just stays on the att logo.. Is there any solution to this problem? I can get to Recovery and download mode. Thank you guys for you help

Try factory resetting again.

I have tried three times still nothing. Been trying to even install custom ROM but all fail to install.

Sgh-i747 4.4.2

Hello all. I just received a galaxy s3 from my sister in law running 4.4.2. I am aware I can't downgrade the complete firmware using Odin. The phone it's rooted. My question is what can I do with this thing as far as playing with roms and what not? Can I only install 4.4.2 based roms? Can I even unroot? I have been rooting and installing roms for years now but never have a phone felt more unfriendly before this. Thanks in advance.

Is the phone running stock 4.4.2?
You can install a custom recovery to the phone, copy some custom ROMs to an external SD card, and try out a bunch of ROMs.

Yeah its stock 4.4.2 rooted with clockwork mod recovery. Do the roms have to be 4.4 or 4.4.2 based? Tried cyanogenmod 4.3 and failed. I pretty much would like to flash via odin to go back to stock unrooted but 4.4.2 was over the air. Got 4.3 via sammobile but that fails. Kies won't show my device for firmware recovery. Shows it as normal to sync.

What error did you get when trying to flash CM10.2? Is your CWM up to date?
I would have assumed that CM10.2 would be comaptible with your KK bootloader and modem.
Do not make anymore attempts to flash 4.3 via Odin. This could result in a bricked phone because a KK modem on a 4.3 bootloader cannot be fixed using any method available on XDA.

Yeah I'm aware of the boot loader and modem downgrade issue. Tried odin once and just left it as is.

Is your CWM up to date? What error did you get when trying to flash CM10.2?

I don't remember the error. According to Rom manager, my recovery is up to date

What version is the cwm? I prefer to manually flash a custom recovery instead of relying on ROM manager.

Cwm 6.0.4.7. I've always used rom manager except for my galaxy nexus. Flashed with windows terminal and fastboot.

Since CWM is up to date, try flashing the most recent CM11.

Older cm roms, and any older roms should run fine on NE4. Some may not flash though, such as cm10. This is because the updater script doesn't include NE4 as it wasn't out when the rom was built. If you edit the script to make it flash, any of the available roms should run just fine.
As it stands though, the easiest thing would be to do as audit13 suggested and flash cm11. That and most other recent roms should flash just fine w/o any extra work.

well, after downloading the most recent cm11 nightly and gapps, rebooted into recovery and wiped. when trying to flash cm11, sd card not mounting. couldn't mount, restored a backup only to be greeted to a display that would not go to sleep and a fury of app and processes stopping pop ups. settings-accounts-backup and reset-factory data reset-etc did nothing but ask for a password. did it through recovery to a perfectly working phone with baseband version: unknown, IMEI: unknown, IMEISV: unknown. flashed the NE4 modem Doc posted in another forum, no dice. same message from cm as before. this time i remember. it was a bunch of basebands not including NE4.

And getprop ro.bootloader says NE4. first said unknown but maybe i typed it wrong.

Got it all back running. tried the S3Rx NE4 aroma zip that would end with installation aborted. found enewman17's post on updating using a stock-rooted 4.4.2 zip after flashing Doc's modem zip. all is well! So thank you DocHoliday77, and thank you enewman17!

Glad you got it working!
