I have a Samsung Galaxy S III Verizon (model: SCH-I535) and its currently updated to its latest firmware, I was trying to downgrade/ root it but it wont work it keeps failing on Odin. My purpose was my main question, is it possible that I could flash a stock SGH T999 firmware on my phone? I would be really grateful if someone showed me a step by step process on how this could be done.
And recently I cant do anything with my phone but officially upgrade it. I think when i upgraded its firmware the security suddenly got tighter, can someone help me about this?
My plan was suppose to be (knowing that 4.3 and the latest firmware on my Verizon prevented me from doing anything): to downgrade to a lower firmware version, then flash the T-Mobile stock firmware.

Today my U.S. cellular Galaxy S III should finally make it here. I apolgize if this is a "noob" question, and have been reading through the forums.
It appears i should get a SCH-R530 model from reading today in the mail. With it being so close to Verizon model, will any of the Verizon ways to root the S3 work with the US Cellular version? If not is there any way currently to root a U.S. Cellular S3?
Thanks for any help

If I'm not mistaken the root method for the VZW SIII should work on that phone. HOWEVER, the same image that is in the dev forum SHOULD NOT be used. It is the stock Verizon with su and Superuser.apk added.
If samsung-updates.com drops a stock image of your phone a system.img can be built so that is flashable via Odin. Regardless, before you go flashing anything you should make sure you have that stock image around so you can get back to square one if anything odd should come up.
EDIT:
If you're interested in building the rooted system image here is the thread where they actually were able to build a clean root from the stock Verizon dump: http://forum.xda-developers.com/showthread.php?t=1762204 It's not a pretty process. The actual instructions used came from this thread: http://forum.xda-developers.com/showthread.php?t=1739426 I didn't see a drop for the US Cell image yet, but I could be missing it. I can be of some help later this evening if nothing has come up.
Root / Recovery / Custom ROM USCC Galaxy S III
I was able to root my USCC SGS3 using Team Epics directions at epiccm.org/2012/06/cwm-recovery-on-all-sgs3-lte-variants.htm
Make sure to apply root.zip. At some point the OTA updated OS so now overwrites custom recovery.
I have Samsungs default ROM on a rooted S3 with CWM recovery. Now onto CM10 (M snapshot). Heard it was very stable.

Just used the Samsung easy update tool to get LK5 on my USCC GSIII (OTA update failed) but want to get root again without tripping the flash counter. Thoughts?
Hey. I have an AT&T Galaxy S4 and I rooted it a while back. When I rooted it, it was on the MDL firmware. Eventually, I wanted to return to stock, so I used Odin to flash the MF3 firmware on it, little did I know, AT&T made it nearly impossible to root with this new firmware. Now, the phone is working running the stock firmware, but I get some weird bugs and also the Samsung Custom splash screen still shows up when I boot it up and not the Galaxy S4 splash screen. Is there any way to fix this? Would using that tedious new way to root the MF3 firmware help at all?
So i was trying to root the Verizon Samsung Galaxy Tab 2, Root Worked Through Odin, And It Boots To OS, thats fine, But The Wifi Button is Basically Broken, and i took the Tab off my LTE plan, I Didn't Bother Trying To Unlock the Bootloader In Fear Of the Dreaded Brick. i'm on 4.1.2, VRBLL2 .....And I'm Looking To Flash Stock Firmware Back And root Using A Different Method,....The Catch!! ... i cant Find The Samsung Sch I705 Official Firmware Anywhere, all links are Broken. Someone Wouldn't happen to have a Copy would They!?!?

hey guys, so im sure many have tried to put cyanogenmod on a VZW Samsung Galaxy s III with 4.4.2 OTA on it. but couldnt. im really looking to put CM11 on it. im very much so new to rooting, and flashing roms, but i already rooted my device, and flashed the stock firmware back, due to not having a CWM back up and getting "system software not authorized by verizon" warning.
so my question.
can i downgrade my firmware from 4.4 to earlier to have an unlocked bootloader without bricking it? do i need to go to 4.3 and then 4.1.2?
because before 4.3 it had an unlocked bootloader.
I really want CM because i cant stand touchwiz anymore. thanks guys . help a newb out
oh and. should i use towel root? or another rooting method
Your now on the locked bootloader and you cannot downgrade to another firmware. You can root with towelroot but that's truly about all you can do
From my CM11 S3
Hey there!
The U11 is my first HTC device ever (I had the Motorola Milestone, Samsung Galaxy Nexus S, Galaxy Nexus, Note 2, LG G3 and Samsung Galaxy S7 Edge).
With the Samsung devices, flashing a stock ROM was very easy. Downloading the stock ROM from Sammobile and flashing it via Odin.
How is it on the U11? The Android 8 update is on our doorstep and I want to do a clean flash, but since I didn't root so far, I really want it to be 100% stock without voiding the warranty.
Is there a site to download the (European unlocked) Android 8 ROM when it's available? How can I do a full clean flash (I don't mind losing all data)? Thanks a lot! I know my way around custom ROMs and flashing, but with HTC devices it's somewhat confusing.
Ruu's don't appear for some time after release ota. If you've never modded your phone you have nothing to worry about. If your phone is carrier locked and you want to change the firmware to unbranded you have to root and s-off.
To unroot back to stock just flash the firmware of the current version the phone is on. You can then take ota updates. You don't need to relock bootloader etc either.
