Hey all, I'm updated to the latest OJC software, rooted with custom recovery (tripped knox). Is there anyway to downgrade to OH6 without bricking the device? They're both 5.1.1 but Didn't want to just try it and I cant seem to find many threads that reference this firmware version. Thanks!
You can flash an older rom, as long as it's 5.1.1. But you can't Odin back to older firmware. You won't brick the phone if you try, but there is some kind of anti roll back protection in the newer firmwares that won't allow it to happen.

Hi Guys,
Here is a breakdown of the facts:
I have a SGH-I747 (Canadian version)
I wanted to unlock it so I downgraded and installed 4.1.1 (I747MUMLL1)
After, I realized that the 4.1.1 is outdated and don't like the layout...etc.
Now, I want to go back to 4.2.1 or 4.3.
What are the steps to install 4.2.1 or 4.3 ?
Do I have to root the phone before installing anything?
Any help would be appreciated.
Thanks
either Odin to 4.3 or check system update in setting

How did you downgrade?

You cannot downgrade the bootloader, only the ROM.
It has been theorized that downgrading the ROM to 4.1.1 and keeping the 4.3 bootloader would give you the necessary options to unlock the phone using the free method, but no one has posted the results of doing this.
I couldn't find a ROM matching MUMLL1 but many ROMs are located here: http://www.sammobile.com/firmwares/1/?model=SGH-I747M&pcode=BMC#firmware

Do you where I can download 4.3? Does it matter on the cellphone provider?
System update doesn't work...its say's system is up-to-date.

Look on samfirmware.com for stock ROMs for your carrier. The firmware must be flashed via desktop Odin.

I read in one of these threads that flashing via Mobile Odin, rather than desktop Odin, will flash the ROM but not the bootloader. Can anyone confirm if it is possible to safely downgrade from 4.3 to 4.1.1 via this method?

I have downloaded lastest firmware for Telus from Sammobile.
Should I just use odin and install the new firmware? Do I need to do something to the ROM before I install the firmware? I'm a newbie to flashing so all the help would be help.

If you are using an i747m, you can use Odin to flash the firmware.
My N7100 has been back fro a local r-shop with 4.4.2 preinstalled.
I did some bad manipulations and tipped KNOX. No problem as my warranty is long over.
Yet is there any possible solution to downgrade to MJ5 BL? I just like CM11...
Thanks
Nope don't try it neither.

Why do you want to downgrade to run cm11, cm 11 runs fine on the newest bootloader. And downgrade is not possible ,if you attempt it via odin it will either fail or brick your device.

Well actually I tried MJ5 with Odin and it failed. I reflashed 4.4.2 and everything is back.
Do AOSP ROMs work with latest BL also?

That's what i said aosp roms work fine with new bootloaders.
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
Edit: oh and btw I accidently pressed the thanks button so you got a free one

cf-auto root, or flash SuperSU with custom recovery.
T999LUVUBNF4 Root
Hey, I've been trying to root my S3 running the T999LUVUBNF4 firmware, but I'm having trouble. Towelroot doesn't support it, I haven't seen anything about a Root66, and I've heard mixed reports on CF-auto root. Does anyone know if there is a workable solution yet? How would I go about flashing SuperSU? Thanks.
Okay I've recently just flashed the root66 firmware that gave me supersu and all that.
My question is... Where do i go from here?
How would i proceed to
1) Install TWRP?, which version as well? Is 2.8 d2tmo fine? Can i have some instructions whether i use TWRP manager(goomanager doesn't seem to exist anymore) or do i have to go into download and flash through odin 3.09?
2) Installing a custom rom? I want to install Paranoid Android 4.6 beta 5 for D2lte but i'm not sure how to go about it. I have already downloaded the rom itself but not sure how to proceed from here. Also, how would i get the working and latest version of Gapps? (Also, can you tell me how to install Cyanogenmod 11 for d2lte as well?)
3) What are some cool apps to get?
4) Which root apps/roms/softwares will brick my phone? I'm never sure which thing will work and which won't.
5) how do i install xposed?
6) How do i remove all the bloatware? and how would i got about flashing through my phone without using the computer? is mobile odin compatible with my phone?
My phone is the SGH-T999L and i have no idea if i have a locked bootloader and how i would go about and bypass the limitations of this locked bootloader

Please don't post the same thing on multiple threads. Not being rude but it doesn't help at all
Rooting SGH-T99L with T999LUVUBNF4
I've read most of the more recent posts, and it is still unclear to me how to root my T999L which is already on the T999LUVUBNF4 baseband and build. I've seen references to cf-auto-root (like serio22 above), but the T999 (which I believe works for T999L) is based on T999UVALEM, which is 4.0.4 ICS. I certainly don't want to downgrade that far. The latest firmware on the first page of this Root66 thread is T999L_UVUBNC1, and there was a post indicating better reception with the newer modem, so I'd rather not downgrade that either. If I flash T999L_UVUBNC1 will my baseband remain intact (BNF4)? Or should I wait for a pre-rooted T999L_UVUBNF4? Or is there a better way altogether to root my T999L/BNF4?
Also, for other n00bs reading this, it's pretty clear that towelroot doesn't work on BNF4.
Thanks!!

rooted Windmobile 4.4.4
anyone have 4.4.? for wind mobile what ever is the new one stock that is rooted ?
I tried flashing UVDLJC - UVDMD5 (latest OTA update) using Multiboot Recovery v2.2 - (twrp2.8.3.0)
When flashing directly onto blank partition, I got some error about missing build.prop, and so decided to try flashing on top of stock ROM.
Stock I have installed as Flash PureStock Rom + Secure UVAMB7 Kernel (from http://forum.xda-developers.com/showpost.php?p=43772060&postcount=3) -- again, in multiboot -- and tried installing OTA on top of that. Got "error executing updater binary in zip"
What am I doing wrong?

slimkat v9 to stock tw
Please help me. I have a sgh-t999. I want to know is it safe to install stock tw t999_uvuenc2. I'm currently running slimkat v9. My baseband is t999uvuenc2 and my android version is 4.4.4 i really want my s3 to revert back to stock. Ive been asking to the roms posted in this unit if it safe to direct flash but i havent got a good advice. I really want the stock touchwiz. Pls help me.
Which firmware to use
After I un-bricked my SGH-T999 with the debrick image sdcard ( YAYYY), I was able to boot with the stock 4.3 rom again.
I reflash the root66 4.3 firmware hoping it could get the correct boot image back in place. However it got stuck at the Samsung logo.
So I went into stock recovery and did a wipe/factory reset. Now I can still boot with the debrick sdcard but I am back in JellyBean (4.1.2 T999UVDMD5).
Which firmware should I flash 4.3 or 4.1.2? And did I miraculously downgraded my firmware ( I thought it wasn't possible) ?

So Im on stock android right now and want to root but seeing that they just updated over the air has anyone else recently rooted from this update without issue? And if so what custom kernel is worth flashing to get root? Thanks. Ohhh Im on Android 5.1.1 of course and baseband of OJ6 which is the most up to date.
I dont think root is available for OJ6
Alright. Thanks.

It does work on OJ6. I rooted mine yesterday after the update. Everything works fine
Hey guys, my last phone was a tmobile device, root and twrp is the norm. Which then I could flash Roms. I saw a twrp is available for us, is this right? Can I flash recovery, and then roms? Or am I missing something? I'm already rooted. I had to root for Sim unlock.
