[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.

Download a stock firmware from samsung-updates or sammobile. Reflash back the stock ROM (Make sure on ND3 or ND4 KitKat bootloader). After finished flashing stock ROM, Flash a recovery of your choice then flash DN5 / DN5+ ROM of your choice.
Note ND3 and above bootloader is a knox enabled bootloader, flashing any other files through ODIN will trip knox.

[Q] Downgrade from Custom 4.4.2 to stock 4.3 possible?

Hi everyone I hope this is not a repetition of some old thread (I tried but couldn't find though).
I was using my note 2 (T889) on stock 4.3 which i previously flashed via odine. A couple of days ago i came by this good looking kitkat based rom ( eZKAT v2.0 ) and went on to try it. the rom flashed flawlessly and after flashing my modem i got the signals as well but the wifi was not working. tried using dr. ketans wifi patch but didnt get the wifi to working. Anyhow, I decided to go back to 4.3 via odine. The odine flashing completed successfully but i got stuck on T-mobiles boot screen for hours.
Is there anything called "you cant go back to 4.3 from 4.4.2"? If yes, then whats the way around? I really need to go back to the stock.
Thanks.

I had this problem on my Note also. Downgrading versions of Android requires a data wipe. You will need to reflash your 4.4 ROM then backup your data if you want. Save your backup to your computer then install the 4.3 image.

I already tried that but still the booting stuck on the t-mobile logo. I read somewhere that locked bootloader don't let you downgrade to previous version. Is this true?

In that case. Try finding a 4.3 rom that's close to stock.
Sent from my Nexus 7

The locked bootloader is always in stock firmwares i.e 4.3 for the Note 2 but not in custom roms meaning u can even install Lollipop custom on it & downgrade smoothly, i have done that many times. The problem is 4.3 stock firmware has locked bootloader hence downgrading still keeps u in 4.3 bootloader even if u remove all the KNOX files.

Stuck trying to downgrade from custom 5.1.1 to stock 4.3
Hi, i have a problem like this, upgrade to a custom 5.1.1 and then sell the phone, the new owner wants to have it stock, i try to downgrade to 4.3 but i cant, in odin i set the phone to flash it but seems like it doesn`t recognize the phone and i dont know why, so, i decided to try in recovery mode installing from the sd card but the sistem abort, so, i don`t know what to do, i`ll appreciates any help, sorry for my english, i do my best. (i have root access before upgrated to 5.1.1).

Does installing a TWRP Backup also affect phone Firmware?

Hello guys,
following situation:
Long time I had a 4.4.something Rom installed. Before I flashed a custom Lollipop rom, I followed the advice to just go back to stock and let it update to Lollipop so that the firmware will be updated accordingly and I won't run into problems when flashing a Lollipop Custom Rom. Everything worked fine. Now I had to send my phone to HTC for display repair and just to make sure they won't nag about the custom Rom I reflashed some older stock rom via TWRP backup I found here, I think it was a 4.0 or so. The question is, does this also affect my phones firmware or is it still on the current newest level? So when I get it back, would I need to update to stock Lollipop again before flashing a custom rom or can I go for it straight away?

It won't affect your firmware.

Okay thanks, so Firmware should still be up to date and I can flash a Lollipop Custom Rom. I don't know what they do at HTC repair, if they only reset it or if they also update it, well I'll see.

Hangs on setup

hey can anyone help me? i've recently reverted my note 2 back to stock via odin and everything seemed fine. When the phone booted and i went through the setup process it always hangs. No matter what i do it always hangs. I've tried reflashing it and rebooting it over and over again but it always hangs. anyone know why this keeps happening?

Are you flashing the latest stock ROM? You're performing a factory reset before booting the ROM for the first time?

Yup latest stock rom, and before i flashed via odin i deleted my previous rom via twrp and formatted internal storage so its 100% clean

I've downgraded a Note 2 sgh-i317m to 4.1.1 from 4.4.2 by flashing a stock 4.1.1 ROM from sammobile.com in order to network unlock the phone. Flashing the stock 4.1.1 ROM tripped knox and could be installed via Odin because the 4.1.1 ROM from sammobile.com did not contain a 4.1.1 bootloader so I wound up with a stock 4.1.1 ROM on a 4.4.2 bootloader. After unlocking, I flashed the stock 4.4.2 ROM again and the the phone worked as it should.
I'm not sure which phone you have and I'm not sure downgrading and upgrading will work in your case but it's something you may want to look into.

I've managed to get the phone working (N7100) and it seems to run fine on Nougat. I did some testing and indeed it would always crash on setup with kitkat roms. I wonder why this is the case....

It is strange that kit kat causes a problem.
Have you tried using a different version of twrp to wipe the system before flashing with Odin? Can't think of anything else that may solve the problem.
