[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] going back to stock after the 4.3 OTA update

I'm currently running beanstalk 4.4.1 rooted with twrp installed. I did the 4.3 OTA update before I went with the custom roms.
what is my options as far as going back to stock 4.3? I've read several threads but non of them were the exact scenario that im in. Any help is appreciated.

Are you running an AT&T phone? If you are, you cannot flash any rom that tries to flash a bootloader that is older than 4.3. If you do, it will brick the phone.

yes it is at&t. Also I do have my original backup but twrp doesn't recognize it

Why not load a 4.3-based ROM? If you want to go back to stock, you could try using mobile Odin to load a stock ROM.

[Q] Flashed the stock rom but it is still showing cm 11 splash screen. . .

So, I'm not a complete noob to flashing roms/rooting devices. I flashed cm 11 to my s3, and decided I wanted to go back to stock via Odin. For some reason when I tried to turn on my device it was still showing the cm 11 splash screen and wouldn't proceed any further. It isn't technically bricked. I guess this would be classified as a boot loop to the nth degree. I tired to boot in recovery mode and wipe the cache partition and all user data to the same cm 11 robot taunting me. When I tried the process (flashing stock vi Odin) again to possibly fix whatever might have been a miss, I got the error message on the download screen "secure check fail: sb12." On the download mode screen it also says I am running the official system rom. I don't know what steps I need to take from here to get my phone to actually boot via the stock rom. Has anybody else had this issue or similar? Any help in resolving this would be greatly appreciated.

Is your phone a i747? If you are you running a stock 4.3 bootloader on your i747, you can't use Odin to flash back to stock unless the ROM was specifically designed to be flashed in Odin.
What is shown on the screen in download mode?

I was under the impression the rom I was attempting to flash was indeed intended for Odin. It is the SGH-I747.
The download screen states,
Product Name: SGH-I747
Custom Binary: Custom
System Status: Official
Qualcom Secure Boot: Enable
Warranty Bit: 1
Bootloader AP SWERV: 2
Here is an added bit of fun, in the midst of the process I accidentally checked "Nand erase all," in Odin at one point.

Based on the information provided, your phone is running a stock ATT 4.3 bootloader. The CM11 splash screen is still showing up because the flash did not actually happen. You're lucky your phone was not bricked in the process of using Odin. I recommend not using Odin to flash a ROM that tries to alter the bootloader.
I recommend flashing a custom recovery such as Philz Touch in Odin and flashing a different KK ROM such as Valudis.

I did. It said the the device couldn't be updated, or something to that effect.

Kies will not work without a stock recovery or a rooted phone from my experience.
I would be surprised if kies can restore your phone as ATT never released a full 4.3 stock ROM. ATT only made 4.3 available via an OTA update.

So, I know there is a "thanks," button but I feel like that would be a little too informal for how much I appreciate your help! I downloaded ADB to move the rom (I went with AOKP because it was the first one that worked) to my phone, flashed it using TWRP and...BAM! We are back in business. Thanks for the direction, I thought I had a nice, new, shiny brick on my hands for about two days.

Canadian carriers use the i747m while att users get the i747.
The Canadian carriers did release a full 4.3 ROM unlike att who did not.

[Q]Need clarification for rooted rogers note 2, android 4.4

Hello, I recently just updated my Rogers SGH-i317M to 4.3, which then downloaded a system update which put it at 4.4. I was running Jedi X20, which is based on 4.1.2, when I first tried updating, I flashed the "4.3param_tz" file in odin, and was left with an error screen saying I need to recover using Kies, so I downloaded the official release, flashed via odin, and thats how I got to where I am now. I want to try the "Ditto Note 3" rom, "Sky Note Air 4.3", "Mean Bean" and "Beanstalk". My main question is, can I just start flashing these roms like I was before on 4.1.2, or do I need to use the specific kernel listed on their page? Before you needed a specific kernel to run a touchwiz rom or an aosp rom, so is it still the same? Or can I use my stock 4.4 kernel and try both aosp and tw roms now? If so could you point out the kernels I would need? And educate me on anything else I should know about before flashing 4.3 and 4.4 roms, (I'm not worried about warranty), this would be greatly appreciated. Thanks for your time in reading this and helping me out, much appreciated!!

Regardless of where u are, I'd Odin to Rogers stock KK 4.4.2. Then Odin Twrp recovery, boot into twrp recovery and flash SU v.1.99. Finally choose your rom and flash away. This way you are on the lastest KK 4.4.2 Bootloader and KK Modem/Baseband.

I did all that except flash SU 1.99, so I tried flashing SKynote Air and it didnt work, upon restarting my phone it said no os is available. So I tried restoring from the backup I made of the official 4.4.2 Samsung rom in twrp, didn't work. Tried Odin, didn't work. Then I tried flashing the Skynote rom again and it worked. So I'm afraid of flashing any other roms now.

Return to Stock From CM12.1

I'm currently running CM12.1 on my phone. I love it, but I want to return to stock and give my phone an "out of the box" feel, and return it to the way Samsung made it to be.
I follow the typical instructions found here, but I always get an error (no screenshot available. Sorry!). I'm running Windows 10 and I have the proper drivers installed. Is there something I'm missing?

If the phone is running a 4.3 or newer bootloader, you cannot flash back to stock using a stock rom from sammobile.
Before flashing anything, I recommend verifying the bootloader and modem before flashing anything else. An improper bootloader and modem combination could brick the phone.

Alright. Thanks. A bit disappointed, but thanks anyway. Besides, CyanogenMod isn't bad.

I was just running CM 12.1 / 13 and I was able to revert back to Roger's Stock ROM Android 4.4.2
Try Odin3 and installing the stock rom. But you should always verify the bootloader.

If the OP is running the i747, it is the the AT&T version of the s3. AT&T never released a full firmware release for use in Odin after 4.1.1. AT&T only released OTA updates that upgraded the phones from 4.1.1 to 4.4.2. In order to flash a stock AT&T 4.4.2 ROM, it needs to be done from TWRP.
