[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] 4.3 Stock for Odin?

Hey guys,
I'm trying to go back to a stock Touchwiz ROM from CyanogenMod 10.2. My only problem is, I can't Odin back to a stock from because the only Odin compatible file I have is 4.1.1 which my phone will no longer go to since my baseband was updated after trying a former 4.3 ROM.
Can anyone link me to a 4.3 ROM that I can flash in Odin? I'm asking because most of the ROM's I'm finding that are 4.3 require you to be on a TW ROM before flashing their ROM. Thanks.

This link is useless for me as it does not have a 4.3 stock rom listed in their official firmwares. They have only up to 4.1.2 which I cannot Odin back to since my baseband was already updated.

Do I have to be on a stock rom to use this? I'm currently on Quantum V3 and I don't have access to a stock rom to revert to since my baseband was updated.

No you don't have to be on the stock rom to use that, but the bootloaders are for 4.3 so if you haven't updated yet this will update you.
You can flash any rom you want to as long as you do not mess with the bootloader you will be OK. I do not know if this work on anything besides an at&t phone using it on anything else is done so at your own risk just the same as using it.

What about the recovery? any way to get a stock recovery image?

Downgrading from 4.4.x to 4.3

I was wondering if I may run into any problems by doing this.
I know that on an AT&T phone (i747), if you do that, you may lose your modem and needs to be reflashed (you get a null IMEI)
Is it the same on a SGH-T999? I was planning to flash this ROM:
http://www.sammobile.com/firmwares/3/?download=26636
Thanks

There is no 4.4.2 to downgrade from for the T999.
If you just have a 4.4.2 Rom, you don't need to do anything.
The firmware you linked is the latest available so you can flash it regardless of what you have now.

There is no 4.4.2 update for the T999 so yes you can flash it but it is not a ROM, it is firmware, please do not confuse these two they are very different!

Yeah... I'm afraid I am confused. What I did was to flash this:
http://forum.xda-developers.com/showthread.php?t=2690947
Isn't that a ROM?
However I would like to go back to 4.3, so I was just wondering if I could have any problems.
Sorry for the noob questions. I think it was clear to me, but I'm afraid it's not...
Thanks

Yes that is a rom, what you linked to in the first post is firmware which contains more than just the system and that is where you run into problems when downgrading

Yes, flash the link you provided in the first post or flash a 4.3 rom.. Understand this, flashing a rom will not determine if you can downgrade or not, flashing firmware will. Since there is no 4.4 firmware for the T999 you can still flash the 4.3 firmware. If there was a 4.4 firmware and you took the OTA or updated via Odin then the only thing you could do is flash a 4.3 rom, firmware will not be an option

Cannot flash stock rom

Hello I would appreciate any help with my device. The problem I am having is I can flash no touchwiz roms such as slimbean and CM11 but cannot flash stock non touchwiz roms. I would like to get wifi calling running but my phone just wont flash those roms. I am using the latest TWRP and my original rom was a 4.2.2 rom but it did not have the wifi calling option. I first encountered my problem when I got the phone and tried to root it and install a custom 4.4.2 rom. The flash failed and from there I was stuck on the Samsung logo. I tried to odin back to stock with the nb4, mk2 and mdl images but odin wil not let me flash it I get nand Write start FAIL error. Tried different odin's, cables, ports and still no go. I know I must be missing something but I have searched and searched and every post says it should be working. Please help.

What is the fail message when flashing the rom in recovery?

Are you sure you have a M919, and not a M919V phone?

Your device is not really a m919....and honestly only mb2 firmware I've ever heard of was actually for the s3 not the s4...there's a bunch of these weird ass devices going around. Both m919 and i9505's. Let me guess you bought it on the Internet?

Thank You all as you suspected the phone was a fake luckily the seller is taking it back.

Still can't connect properly to the network

It's been another few months and still the same problems with all ROMS i try, when the screen is off i lose connection to the mobile network, When i turn the screen back on it will connect and start buzzing and alerting me to every unread message and e-mail Which gets annoying very quickly let alone missing messages and calls.
This happens on CM 12, Pac man rom, GPE and others. Both with 4.4.4 and 5.0. CM 11 works fine for me without this issue.
I see people say they are using these roms without this issue so something is definitely wrong but I can figure out what.

You may need to update the baseband a bootloader in order for the phone to work properly with the latest ROMs.

Thanks for the reply, before i screw anything up there doesn't appear to be any explicit guides. I'm assuming i use this guide http://forum.xda-developers.com/showthread.php?t=2678774 with the OK3 Rom. beyond this is there anything i should know, like will i have to unlock and root my phone again, or anything like that?

The stock ROMs for the sgh-m919 are here: http://www.sammobile.com/firmwares/database/SGH-M919/
The simplest way to update to the latest bootloader and modem would be to flash the phone back to stock using the above-linked software.
Once you are on the latest stock ROM, flash the latest TWRP to the phone. Once TWRP has been installed, you can flash a custom ROM. Rooting first is not necessary if you intend to run a custom ROM.

Sorry for the late update but I got it working thank you.
The FOK3 and FOH3 didn't work for me, once installed it still showed the MDL version. Once i did the FNK2 it worked.
Is there a reason to upgrade to the FOH3 or FOK3 from the FNK2 versions provided i can get them to work?

I always recommend running the latest bootloader and rom but, if the bootloader and modem work without issue, you can hold off.
