I have a stock unrooted SGSIII that received the latest NJ1 firmware. Is there anyway to root this phone or flash a custom recovery?
I am familiar with flashing past Samsung phones, just not with the SGSIII nor facing boot locks.
If there is no current method what is likely to happen if I take the rooted boot and system images from the end of this post and package them into a .tar.md5 to flash with ODIN? Testing things with the boot image is asking for trouble so I would prefer to minimize the risks of bricking (are there viable unbrick procedures in this case?).
Have you tried towel root? Or is your kernel already patched?

This phone is 100% stock, never rooted, and recieved the latest OTA update a month or so back.
I have root in my stock & recently upgraded NJ1using this: http://forum.xda-developers.com/showthread.php?p=56787105
Odin your favorite recovery and flash SuperSU
Doesn't that procedure require you to be already rooted in a previous firmware to begin with?
As it is, attempting to flash a custom recovery image with Odin returns the error "SW REV CHECK FAIL" and fails.
I just odin TWRP and flashed SuperSU.
I got this phone 15 days ago and not knowing I upgraded to NJ1, so no previous root.
I'll check it again, thanks.
Which TWRP download did you use?
UPDATE: I got this to work by downloading TWRP, Odin, and the Samsung drivers from previous threads. Thanks, developers!

So I'm by no means super knowledgable with this stuff but I've rooted a few phones, played around with CM on my old evo but for the most part I enjoy rooted stock.
I have Galaxy S3 Sprint 4.3 updated OTA from a rooted (4.1.2). When I took the OTA I lost root, no big deal I used Odin and flashed the CF auto root, it said it removed knox and I had root back. Cool!
In short 4.3 sucked, wanted to downgrade back so things like TrevE mod would work again and it wouldn't be so buggy. I tried to use odin to flash "KIES_HOME_L710VPBMD4_L710SPRBMD4_1130792_REV03_user_low_ship.tar.md5" but it gave me the "Use Kies Recovery and error occured" message.
So I then used odin and flashed TWRP and my phone booted.
I'm back on 4.3 rooted.
I've tried picking through the forums and interwebz for answers but I get mixed messages and info on international versions and what not.
I'm tired of trying to figure it out and really could use some help downgrading back to 4.1.2
Thanks,
Brandon

The 4.3 OTA installed a locked bootloader, which will prevent you from ODIN'ing back to a previous version. you can flash any ROM you would like from recovery, you CANNOT downgrade the bootloader. As of right now, if you have knox, you are stuck with it.
You are extremely lucky that you didn't brick your phone by using odin to flash a non-4.3 tar. I wouldnt try again.
My advice is, remain rooted with a custom recovery, and find a ROM to your liking, and flash that.
I have also heard that we cannot flash custom kernels on the knox (MK3) bootloader as well, but I havent verified that.

Thank you for the response. Is CyanogenMod an option then? If I go to CM could I flash back a stock 4.3 rom in the future?
As an added bonus question does CM allow wifi tethering?
Again thank you for the response.

CM is certainly an option. In fact, its what i am running now. CM11 12-24. Runs great. You can always odin the stock mk3 tar and go back to stock unrooted, at any time.
in order to flash cm11 you MUST be on TWRP 2.6.3.1 or CWM 6.0.4.5 or newer or the assert check will fail.
not sure on the tethering, but im pretty sure it definitely works on cm10.2 and i think it does on 11 as well, but dont quote me on that.

Tethering is available on CM11 just like it was on 10.2; would strongly recommend latest Philz Touch Recovery over either TWRP or CWM though. Although it is based on CWM, it has proven to be pretty much the superior recovery option for flashing any Android build number, plus it is highly customizable.
Philz Touch Recovery
this is how to downgrade

Do you realize that this thread hasn't been used in a couple of months? I would assume the author has no more need of advice based on the inactivity. Also, once Knox is installed, it is on the phone to stay. PERIOD. NO DOWNGRADING POSSIBLE VIA ODIN. Custom ROMs of any build are fine via custom recovery, but any attempt to change the bootloader will trigger Knox and brick the phone. Dangerous info to be posting here, especially since someone else who doesn't know better might try this.
Okayy ive searched around and looked through ALL the threads and guides on rooting this phone and even followed some but im still stuck. Yes ive read and searched before asking so now im asking, is there any thorough guide or youtube vid maybe that shows how to properly apply full root to the T999N version of the galaxy s3 on metropcs? Im updated to 4.3 btw. Please no sarcasm/smart remarks
Did you try Root66 4.3 version ?
Best if you can flash a Custom Recovery via Odin and then flash SuperSU package through that Recovery.

Ive tried to flash the recovery through odin but even though the box says PASS and reboots my phone, when i go into recovery mode it takes me to stock android recovery. I need help
Make sure that Recovery is compatible with your phone. Second post the complete odin log for that process.
I have it rooted now, just have to figure out a way to update twrp without removing root

Take least TWRP and Flash via Odin.
Where can I find the MK7 kernel, that's the only way I can get wifi to work.
Hello,
I messed up my Note 8 and recently was able to reinstall 4.1.2 stock, I tried connecting to Kies and it doesn't work. I wanted to update to the newest software then root. Since that wasn't working I rooted via Odin then attempted to flash twrp so I could flash a custom rom. Root works but the custom recovery doesn't stick... I tried unticking reboot in odin and the system still reboots into standard recovery.
I tried using the toolkit and its stuck on waiting on debug even though debug is clicked.
Can anyone help me install a custom recovery via odin or another way?
If you have the at&t sgh-i467 version - there is not a custom recovery for it because it has a locked bootlader.
Additionally, the newest 4.4.2 ota update has not been rooted as of yet - so if you must have root, don't install the ota.
The original mf1 rom is rootable, but again there is no customers recovery due to the locked bootloader.
This only applies to the at&t in version...
use Odin
Need help?
I rooted my dad's phone a while back ago so he can use tethering in case of emergencies etc. He recently got a smart watch and I wanted to updated it so that he can use it. But it has not been touched since that day. I essentially want rooted stock rom, I'm unaware of where to find that the closest I can find is StockMod kitkat. Which seems to not work on ATT phones? I just want to make sure that I don't brick his only phone on christmas. So is there something I should be aware of?
His model is SGH-i747
Baseband
i747UCDLK3
Build number
jro03
So how do I go about upgrading it? Can I just flash TWRP and flash any rom using TWRP?
I found this, so I should install new TWRP, then flash a specified kernel then flash rom? would this be safe route?
Some of the latest ROMs require a 4.4.2 bootloader and modem.
The simplest and safest way to get the latest bootloader may be to flash back to unrooted stock 4.1.1 and run OTA updates until the phone is running the latest KK ROM. You can then flash TWRP or CWM and a custom ROM.

Would this require flashing with ODIN? I just want it so that it works with root is not required anymore.
Yes, you would flash the 4.1.1 stock ATT ROM via Odin. I prefer Odin 3.07.
You cannot install OTA updates with root.
You can try flashing just the bootloader and modem but I prefer the long slow route of OTA updates.
I rather do it this way, manually so my dad can enjoy it today. I was wondering how can I update it's TWRP? it's at 2.3 but the TWRP manager keeps crashing when I update it.
I highly recommend the latest d2lte version of Philz Touch for recovery.
https://goo.im/devs/philz_touch/CWM_Advanced_Edition/d2lte/
Ok I ****ed up, flash that kernel and did whatever and bam ****ed up. Not working... ****, I still ahve download mode and Recovery but it will not boot into the OS. I get a flash of samsung and then nothing else happends...****
I decided to flash stock DLK3 in odin. Then let the updates take it course (my dad doesn't need root) Where Can I find the file?
The stock ATT firmware is on sammobile.com.
If you want root, OTA to the latest 4.4.2, install Philz, flash supersu via recovery.
Confused about rooting with T999UVUEOH1
ok
If the phone is running a stock 4.3 Samsung ROM, the phone will have knox. Best thing to do would be to run OTA updates until the phone is running the latest ROM. This will ensure that the phone has the most recent bootloader and modem.
Once updated, you can easily root the phone by flash TWRP for the d2tmo via Odin. After installing TWRP, you can flash supersu 2.45 or 2.46 via TWRP and have root access.
Note that flashing TWRP will trip the knox counter.
Ok
The method I recommended should not cause any loss of data. To be safe, always backup before flashing anything.
Is there any warranty left on the phone? If not, tripping knox isn't going to matter.
Any attempts to downgrade the bootloader may result in a bricked phone.
Looks like the root66 method involves flashing a prerooted stock ROM. If you want to try the root66 method, just make sure the root66 ROM's bootloader and modem are the same or newer than the phone's version. If the phone has oh1, I would not use the root66 method.
Ok
Flashing TWRP and supersu from TWRP is the easiest in my opinion.
Just make sure to get the tar version of TWRP to flash in Odin.

Nahh!! The easiest way is use TowelRoot
Only need to press a button! I'm using that firmware so I CONFIRM that it's working
I guess it depends on the rom. It wouldn't work on stock 4.4.2 for me.
The kernel was patched against Towelroot in 4.4.2. We were never updated past 4.3 so it should work fine.
