UNROOT sgh-t999v

i need to unroot my s3 for warranty purposes but i cannot find proper procedures for the the model sgh-t999v..
i have 2 questions,
1. can i just root a stock rom for sgh-t999 to my sgh-t999v?
2. anyone have the procedures to unroot my sgh-t999v
thanks

Flash a stock rooted Rom. T-Mobile one. That seems to be ok as long as you don't flash a T-Mobile radio.
Not sure if triangle away works on the Canadian version.
Maybe someone else has tried it.
All I had to do to return my last one was flash a stock rooted Rom.
I don't think they check the flash counter

If the Rom has some T-Mobile bloat left on it get it off there.

Or you can download the actual fw for your device. You will have to register but its no big deal.

I can see you have a Videotron Galaxy S3. They don't check the flash counter. Let's just say I know this "by experience". As long as it's just rooted and you don't have any custom ROM, you should be fine. But indeed if you can at least hide the SU app it would be a good thing.
You could also perform a factory reset in CWM prior to going to the store, as they will make you do it anyways (and you actually don't want them to see the CWM screen)prior to any exchange. It's company policy.

It's still probably safer to just use Triangle Away to get rid of the flash counter

Triangle away? Please explain

Hi,
Can we use the T-Mobile stock recovery on SGH-T999V?

If your trying to go back to stock, just download the stock rom from sammobile, it has everything you need like stock recovery, and then just flash it via odin.

Hi,
The only downloads availables are the firmwares, does it include the stock recovery in it?

Yes it should be the full fw which includes radio, recovery and more.

Thanks!
I'll test it tonight, wouldn't look good to download a 700 mb file at work!

I tried a few firmwares, but for some reason they all said "unsupport dev_type" when trying to use odin to return to stock non root (from stock rooted) In the end, the easiest way to remove root was to just let Kies update my gs3 to Jelly Bean (sgh-t999v). Painless, no data loss, took about 30 minutes with the firmware download.
Good luck

You will likely also want to triangle away. I won't link because it's extremely dangerous software that requires you to read up on the risks.
But that will reset your custom flashes assuming you have some on your counter you can check easily by going into download mode.

i recently lost my stock rom backup.. deleted it off clockworkmod touch by accident, so i only have the cm10.1 nightly i was running when i deleted it.. now i'm assuming i will lose root if i flash the stock firmware through odin? is there another way to get my stock rom back without losing root (and cyanogenmod rom backups)?

hey guys im having trouble with triangle away on my sgh-t999v with the baseband version: T999VVLUFNF1
after I used triangle away and I go into download mode it says:
current binary: Samsung Official
System status: official
qualcomm secureboot:enable
Warranty Bit:1
Bootloader AP SWAEV: 2
Although the current binary and the system status have changed the warranty bit is still at 1
Please help!

There is no way (and never will be a way) to change the Warranty Bit. Sorry

I guess im screwed for warranty..I thought it might be cuz I have a custom kernal installed that triangle away didnt work..but thanks anyway and sorry about posting in multiple threads, im kinda new to this

No problem, thats why i mention it, so you know for the future.
Tecnically, with the warranty bit tripped, the warranty is void. However, i have seen a lot of posts where people sent it in anyway and their warranty was still honored. Its not a guarantee, but there is hope it can be used if needed. The good thing though, is you most likely will never need to use it anyway!

[Q] Getting back to 4.3, is it possible?

Hi all,
Starting from the beginning... I had been having issues with CM 11 (LTE issues) so I decided to flash stock 4.1.2 (which was lag-galore) and upgraded to 4.3 to see any performance improvements. I was terribly disappointed with stock 4.3 for it extremely slow. laggy and sluggish as compared to the buttery CM. (I also did many tweaks in dev option and factory restored but my phone just wont stop lagging)
So basically I am wondering: Can I root 4.3, flash a custom ROM and if for any reason I have to, FLASH BACK TO STOCK 4.3?
I want to sell my phone down the road and my original plan was to flash 4.1.2 stock but with the bricking issues involved while downgrading I want to know if I can go straight from custom to 4.3 stock.
Thanks in advance for the help!

Yep you can always Odin back to stock 4.3, just not lower. I know with the M version you can anyway.

If you have an i747m (Bell, Telus, Rogers), there is a complete stock 4.3 ROM. For the AT&T s3 (i747), there is not stock 4.3 ROM as AT&T only released their 4.3 ROM as an OTA update.

I've been searching the forums for a compete Stock Rom but like Audit as mentioned there is none for Att. I guess I just have to continue with stock.

maybe its just me expecting too much from my phone. Compared to CM 11, I feel touchwiz is soooo slow and stutters and lags and is just plain behind. I did a factory reset myself with no noticeable change so I guess that's the way it is.

[Q] Need advice resetting to stock 4.2.2

I'm planning on upgrading to another phone so I'm trying to get this counter on my phone reset to 0, then unrooting.
Right now I am on the latest version of Insanity ROM Android 4.3 MK2 Baseband .
I tried resetting the counter using TriangleAway earlier, but I noticed I needed to be on a stock Samsung kernel.
So I found one (and this same thing happened when I tried to flash a stock rooted ROM with MDL) on XDA directly for the T-Mobile S4, only to find out that after flashing, it wouldn't get past the black screen after the SGS4 logo comes on.
Luckily, I restored back
I know how to unroot and everything I just want to ask before I do this,. Can I go ahead on using Triangle Away on my current rom? And then do the unrooting process?

If you took the OTA 4.3 you are Sol. If you still have the MDL bootloader you can Odin the MDL stock image then root and triangle away and then unroot. You will be good to go then.

No, I never had it updated when I bought it from Tmo as Android 4.2.2 . So you're saying with even with the current custom 4.3 Android & custom kernel that I have right now I can Odin the MDL? (Unroot, Root, TriangleAway, unroot?)

Yes. If you never took the OTA and only flashed the mk2 modem you can absolutely Odin the stock MDL ROM and root, triangle away then unroot (in that order) You'll be good to go then. Just make sure you're binary found is at 0 by booting into download mode when you're done.

But me being me as soon as I opened the phone I updated it to 4.3 then rooted it not knowing I wouldnt be able to return to stock! Even tho I did backup my stock rooted phone my phone will not let me restore to it so I've been stuck on beanstalk 4.4 but really want to go back to stock rooted cause of the camera!! Haha.... I'm new to the s4 so I'm still learning more about it I had an s2 before this and that was all cake walk flashing and what not. I just want to know if Odin is an option for me to return to stock or not?? I think I backed it up through lies before ota 4.3

From what I've read in other threads you cannot downgrade bootloaders so if you took th OTA you can't go back to 4.2. From what I understand it will brick your phone. If you are already 4.3 and rooted you have already voided your warranty. You may as well Odin the stock 4.3 and root again so you can flash other Roms since you are stuck on 4.4.

Help Updating (Sorry for noob question)

hey guys have been out of the modding life for a long time now since HTC Amaze came out on market and ive had nexus' (galaxy nexus) since then. i had a quick question. my sister passed down to me a S3 T-Mobile one. its on 4.1.1 and i had at the time put in CWM long time ago as i was gonna flash custom roms but never got around to it (i did this with the help of a youtube video.) now i have this device the Volume UP button doesnt work which is essential to go into download mode... how would i go about updating this to the latest 4.3 Firmware? if there are any detailed steps id really appreciate them. Sorry i know it sucks to get noob posts like these but i have done a bit of research and i cant seem to ask the right questions on google! thanks
btw just for though im switching from nexus 4 to s3 just cause i dont need the power from the n4 and i just want the s3 screen

so i think i found the piece i think its here: http://www.ebay.ca/itm/T-Mobile-Gal...cement_Parts_Tools&hash=item4d14d4fdbd&_uhb=1
is there a demo on how to do it or should i take it to Pacific Mall and get someone to do it? how much would it cost anyways?

You only need volume up to enter recovery.. volume down is for download mode.. anyway there are apps that can get you to download or recovery mode as long as you are rooted.. you could do that meanwhile or just wait till you fix the button.. really all you have to do is flash a 4.3 rom and modem in recovery, no need to update the whole firmware
Sent from my SGH-M919 using Tapatalk

Being on 4.1.1, itd probably be a good idea to update the firmware. Thats just my opinion though.
You can root without volume up working, and or flash roms like serio said.
As for fixing it though, if you are good working on electronics and have good manual dexterity, you could probably do this yourself. But the advantage of taking it to a shop is if they screw it up theyd probably have to replace or reimburse you for it.
Sent from my SGH-T999 using Tapatalk

what if i want to flash cyanogenmod11? is there any step by step? i dont want to brick this phone
do i have to update baseband?

First thing is to get rooted. Easiest way is to flash the root66 firmware via odin. Now decide if you want to use cwm/twrp recovery, or Mobile Odin to flash your rom.
If you want to use recovery, use goo manager or rom manager from the store to install the recovery. Then from the app choose reboot recovery and flash your rom. Factory reset after and reboot. Thats it.
You may need to update your firmware to at least 4.1.2. I think cm had issues running on older firmware.

isnt cm going to be 4.4.2? hwo do i update ? im fully rooted and running CWM 6.0.4.5 Touch ^^ dont know about TWRP but ive been using CWM for the longest time before so i trust it

If you want to skip updating firmware, just flash the rom from cwm. If it errors out youll need to update to at least 4.1.2 (official or root66) via Odin.

Go to the firmware thread stickies in development (and linked in my Sig). Download the 4.1.2 firmware (or 4.3 if you choose, up to you), and flash using PC Odin.
Mobile Odin, while awesome in its own right, cannot update your boot loader and other important parts of the firmware needed by CM.

updating bootloader and modem

i have att s3 i747. under baseband it says i747ucdlk3.
I want to install and experience with more roms, especially the lollipop nightlies. but they require an updated bootloader! Otherwise, my phone doesnt read the sim card. i have read so many threads on how to update the bootloader and modem/firmware, but half of the threads i read result in many people bricking their device! How do i update the bootloader properly? that is, without bricking my phone of course! should i do incremental updates? or jump from lk3 to the latest one? im lost on what to do, like i said so many people got bricked. can anyone help me out? it would be greatly appreciated!

i used this to get to NE4 with no problems.

One question: did u use this to update from lk3?
Sent from my SAMSUNG-SGH-I747 using XDA Free mobile app

Is your phone sim unlocked? If it isn't, you could flash back to a stock AT&T 4.1.1 ROM, unlock, and run OTA updates until your have the latest ROM on your phone. This approach requires more time but it is the simplest and least risky in my opinion.

So basically you're saying to flash back to unrooted stock. And then keep using att updates until I get to the latest one, and then I should be on ne4 automatically?? Not sure if I'm understanding this correctly.

Yes, flash back to stock and keep running ota until you hit the latest release.
If you have warranty left on your phone, updating, rooting, and loading a custom recovery will change the warranty bit from 0 to 1 which voids the remaining warranty.

K will do when chance the chance. Btw. Isn't there a requirement to not go past a certain firmware if I wanted to revert back to stock or else it'll brick? I thought it was if I go past 4.3. Any ideas?

You will have no choice but to flash to 4.4.2 bootloader and modem if you want to run the latest d2lte ROMs.
True, once you are on 4.3 or higher bootloader, you cannot go back to stock 4.1.1.

i had read of some people have to use ktoonz kernel to get wifi , but that is usually in the OP.
thank you once again @audit13 for coming to the rescue. i am now M8 and losing what little i747 now-how i had. lmao.
"all i can really do , is stay out of my own way and let the will of heaven be done"

So since I'm on lk3.. I should still be able to flash black to 4.1.1 stock via Odin and then use the ota right? Or should I flash back to 4.3. Which one is the safe option? Im thinking about using the ota option mentioned earlier in this thread.
