Is it possible to downgrade? - Verizon Samsung Galaxy S III

My girlfriend went full retard and installed the OTA 4.3 update for her S3. She uses Straight Talk, which works on the OTA 4.3 download. The only thing that doesn't work is 4G. She is stuck on edge. I think the best solution to getting 4G is to put a ROM on it BUT in order to do that I need to revert back to 4.2.1 or so. Any thoughts? I havent found anything on here that explains how to do so, but if I missed one please send me in the right direction.

AFAIK you are stuck on 4.3 but can use safestrap.

I looked on the development threads and didn't see any ROM's for safestrap

If you're on straight talk you can't use 4g. Even with safestrap you won't be able to use anything other than 4.3 TW roms

Camera problems

My camera doesn't work on any rom. It opens then force closes saying "camera not connected" or "camera not working".
WHen i restore to my stock backup It works fine.
I've tried these roms in this order:
synergy
liquid
cm10
axis
all latest updates
I use TWRP 2.5
When i originally rooted i used ODIN and followed it to a T.
Like i said being stock my camera works. When i flash a rom it doesn't. Also i try reflashing, fix permisisions. no luck......... Seems to be the only thing not working too. Only problem is I have to have my camera!
Any help would be great!
Tony
I have the same problem and still haven't figure it out, tried all types of solution none have worked still "can not connect and failed "

But when you restore your stock backup your camera still works?
Did you flash anything from the new update? Or are the roms that you are on based on the new one?

When i rooted my phone... 2 days ago
I was only the latest samsung over the air update.
when i was done rooting I made sure everything works then did a back up so i can always revert.
When i flash any of the roms I just flash the latest available. If it requires gapps i use the one for the build it's for. 4.1 or 4.2
And like i said I'm on twrp 2.5
The fact that it works stock tells me it's software and maybe related to TWRP? but i can't figure out how.
The new update is the problem, it breaks the camera if your rom is based on the old firmware.

OK ,now I get to sound like a noob
So what now? I'm guessing flash a old Samsung stock then root? But how and where
I've been rooting and flashing different devices for awhile but never had issues'
I really appreciate all the help!
I'm not the best at explaining things. I just went back to my backup and stayed with that. My camera works fine now.
I'm sure someone will come to help and explain it better.

There is a custom firmware package that has the MD3 bootchain and the MB1 modem that will work across all roms. I'm at work now but I'll try to link it when I get off. It's somewhere in the BoneStock ROM thread if you feel like finding it yourself.

Seems to be an almost daily occurrence. Reading a new thread about the camera issue that has been documented and the solution posted time and time again.

Just updated the kernel to the new kt747 jb 4.2 june 8 2013 and the camera works.
Flash mb1 firmware, the modified file someone is talking about is simply the md3 modem with an mb1 tz. The md3 modem gives shotty data connection for most people and the mb1 radio will probably work better for you.
Just flash the mb1 firmware aio package, that should fix your problem.
Please try to search next time, this question has been answered everyday for a week, and this method works for almost everybody.

Hello Friends, This is BRICKBEATS and I have just COOKED my first custom rom for the Verizon Samsung Galaxy S III 4.3 from the recently released update. This is stock WITH KNOX APPS REMOVED AND SOME VZW BLOAT REMOVED, and was supposed to have root but it doesn't seem to work at this time. THIS IS A CWM FLASHABLE ZIP AND DOES NOT FLASH THE SECURED BOOTLOADERS, MODEM, OR RPM FILES!!!! I just flashed it to my phone less than an hour ago so any bugs are unknown as of yet. I figured we could all test it out and any input is appreciated. I will get screen shots soon!!! Enjoy
edit: wifi is broken
edit 2: give a decent amount of time for that first boot, it may take a battery pull and hard reset..

I think I know the answer to this but I just want to make sure. If we flash this are we still able to revert back to 4.1.2?

i would think so, since its only flashing the system, cache, and kernel files in CWM

Yes if you do flash this rom you can in fact revert to 4.1.2 or any version of android built for this phone for that matter. All this is doing is just installing a rom that has the 4.3 base. If you do decide to go back, just flash a rom thats built on any other version of android for this phone.
this is actually a better rom option with more functionality...

Just to be clear, if your gs3 has the official 4.3 on it, you CANNOT unlock the bootloader. You WILL brick your phone if you try.
Safer not to mess with it at this point imho

I definitely appreciate but cyanogrnmod is why I bought the phone. .. I'd there a way to possibly uninstall the update in that case or would I pay much have to wait till cyanogenmod comes or with something to get around Knox? Truthfully a good reputable stock android feel Rom installer would be nice but I'm super noob status when it comes to this and would appreciate any assistance

Nothing you can do right now as far as custom rom. Currently a few folks are working on a patch for safestrap in order to flash custom rom (currently only able to flash custom TW rom). You can follow this http://forum.xda-developers.com/showthread.php?t=2618887 to see the status.

I have just received a replacement phone. I have gone about the ways I rooted previously and none of them are working. This did NOT come with 4.3 from the factory, and the 4.3 update is not installed. I reverted back to stock from android recovery, so 4.0.4 is on there right now. But no matter what I do, whether it's the one click method, the GS3 toolkit format, or manually trying to gain root through recovery, nothing works. On the "downloading" screen that you need during use of ODIN, it says "SECURE CHECK FAIL", and it'll either have "boot" after it, or "kernel". Anyone have any ideas? As of this moment I have no working phone. Looking for some help asap. Thank you guys.

Try to Odin flash factory 4.1.2 and see if the secure check turn to "enabled". If it's then try to root again.
I just Odin flashed a stock 4.1.2 ROM actually. It's booting up normally now. It honestly seems like they added a layer of protection on the newly distributed handsets. I will try to go through the normal 1 click method again and see if that works. How would I check if the secure check is still enabled?
Actually, no, it's still 4.0.4 but I'm going to try the same thing just with a different 1 click method.
Looks like the really old way worked. With the ez-unlock and ez-recovery. I had to completely demolish what was there when it was sent to me, though. So anyone who gets a replacement, the best bet is to flash a fresh 4.1.2 ROM or 4.0.4 ROM immediately, boot back up and go from there.

Q: do I need root to downgrade android versions?

Verizon of course crippled my phone with the Ota of 4.3 I took.
I've lived with this looks g enough. Random lockups, needing a better pull. Camera failures.
I don't want or need to mess with root it just want to go back to my last stable build, whichever it was.
Can someone direct me there? Do I need to use Odin?
Where can I find safe original firmware?
Thanks I'm advance.

You can't downgrade, you're stuck with 4.3 because of the new bootloader.
You can install safestrap after you root it with saferoot. That will allow you to install 4.3 TouchWiz roms only.

Okay.
Are there any roms thus far that are t garbage?
From what I've read the issues I have effect most of the galaxy line.
So then.
1. Obtain root
2. Install a bootstrap that allows a custom rom in spite of the relocked bootloader?
I presume these guides exist here. I'll research them.

[Q] CleanROM Wifi not working

My phone was making me really mad because it was super slow, and could barely type anymore, I did everything so I factory reset and flashed a rom.
My wifi no longer works, and I'm not sure what to do next. I just want my phone to be usable again.
I just flashed MOAR Rom, and Wifi is still not working.
If you are using Safestrap, download the VRUCML1 kernel modules from the Safestrap thread and install those when you flash a custom TouchWiz rom.

Thanks for the reply but I managed to brick it and then I got it back to stock using Odin. Now Safestrap doesn't work and I just downloaded 4.4, I always screw up stuff like this. I only have 5 months left with my phone so It doesn't really matter. Perhaps there will be a way to root on 4.4 one day.
