[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.

Custom ROM 4.3 to. kitkat 4.4

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:
http://forum.xda-developers.com/showpost.php?p=48544617&postcount=255
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.

[Q] Need help about stock 4.2.2 firmware

Hi,
I've got some issues about stock 4.2.2 firmware. My phone lagged on AOSP roms(4.4.2 Kitkat) and someone told me to try flashing an older stock 4.2.2 firmware before flashing AOSP roms.
My questions are :
-Where can find 4.2.2 firmware to download and which one do I have to use and how to?
-Do I have to go back to 4.2.2 official ROM first before flashing or I can just flash it even i'm on AOSP 4.4.2 Kitkat rom.
Please explain every steps and sorry if it was stupid questions.
Thank you so much

1)Actually bnb2 Official Firmware is WORST ever firmware update... right now best is K3 firmware u can download it from here http://samsung-updates.com/device/?id=GT-I9082
2) No need to go back to stock for installing different ROM...Best is flash Philz Recovery can be found here http://forum.xda-developers.com/showthread.php?t=2725019
This Recovery has a option called Install New Rom which cleans everything which is necessary for a New Rom To work flawlessly.
OR ELSE
First go to Recovery do Factory Reset,Wipe Cache,Dalvic Cache, Install The New Rom and after that Factory Reset,Wipe Cache,Dalvic Cache and then Reboot..Enjoy!!

How can I return to stock ROM?

Hi everyone, so I'm looking to return to stock ROM as I am getting rid of this device. How would I go about getting back to stock ROM, so that the person I'm giving it to can then auto update? I had a quick look for a nandroid as I stupidly forgot to backup myself!
I'm on T705 by the way.

Search xda to see if someone has posted a stock Rom for your device. If not, you have to down load it from sammobile.com which is slow. Then do a factory reset to wipe your data and flash the stock Rom with Odin.
It will be ok if you put on an older stock Rom because once connected to Wi-Fi it will update over the air.

How to switch ROM? From Lollipop back to stock, help!

I am running stock right now (JB 4.2.2) and I am planning to flash a Lollipop ROM (AICP 10). If I create a backup (for my stock ROM) at TWRP and did the needed measures to flash the Lollipop ROM and was successful however I want to return to stock ROM. Do I just have to factory reset and restore my stock ROM backup to have a stock ROM again? Sorry for this noob question.

Heeeeelp!
Any idea if that would work?

Just use odin to flash any stock rom

So backup-ing in TWRP before I flash Lollipop from my current rom [Stock JB 4.2.2] is useless?

You can also use your backup from TWRP.
But It will then show that it has been modified, could be a problem with the warranty.
If you want to go back completely for warranty then odin is the way to go

Thank you! I actually don't care about warranty since mine is overdue already. All I wanted to know was if I will be able to go back to JB 4.2.2 with that backup in case I have problems with Lollipop.
