How to unroot and relock phone?

Sorry if this has been asked her before, but I've done a search, and it doesn't seem to come up at least here in the AT&T S III forums.
I'm going to need to send in my phone for return, and was wondering how I might unroot and relock the bootloader on the phone. I'm hoping the process does exist, and it seems like chainfire has an app to reset the flash counter.
Thank you SO MUCH in advance.

Also wanted to mention that I've installed clockwork recovery... which I assume needs to be replaced.

and the bootloader is NOT locked on the At&t GS3 so don't worry about that.. ..hope this helps.

[Q] Update bootloader?

Device: AT&T Galaxy S3
Rom:[ROM] AOKP(Jellybean 4.2.2 )Task650 (5.14.2013) (AT&T)
I wanted to update to the devs newest release but i need to update my bootloader in order to do so and ive never done that so if you have any advice or something i can read up on that would be awesome

I "I made some ODIN-flashable files that contain the bootloader, RPM, TZ, and baseband of the stated versions , so that people won't have to go completely back to stock TW. It's intended for those not on the necessary bootloaders yet so that they can flash future CM builds. Put them into the PDA section in Odin and flash away.

I747MVLDLK4 (Canadian): http://d-h.st/yqV
http://www.mediafire.com/?74b1e321p537f5d
Note: They're untested, but should work as intended. Tested by fellow users, works fine. Please flash at your own risk!
EDIT: Threw up Mediafire mirrors, since d-h.st seems to be down randomly."

it's pretty simple and harmless. took me less than a minute. Domoo has linked you to Jiangyi's post on this topic, which includes his downloads and instructions. cheers

well that was easy thanks for the help guys!

Flashing a bootloader is not harmless. It is one of the few things that can hard brick this device.

Because it was a good warning. Flashing a ROM should not be taken lightly and flashing a bootloader should be done with alot of care as it can brick your device to the point of needed a JTAG to fix.

yes, bootloaders are very serious business. just because this bootloader flashed without error does not mean that the operation is not serious. take note, OP.

As long as your bootloader ends in a dlk3 then you have the most recent one.

You can check your bootloader version by opening a terminal and typing:
Code:
su
getprop ro.bootloader

I747UCDLK3. Most current. Got it from At&t recently...I am surprised that they did the update. I didn't let the phone OTA either. Honestly, though I didn't look, flashed it out of the box.

I'm on Rogers, with bootloader I747MVLALH1, haven't flashed anything since mid April. Should I use ODIN to flash the I747MVLDLK4 bootloader? I was planning on updating to a newer CM10.1 nightly and just saw that I needed a new bootloader to do it properly.

The I747MVLDLK4 bootloader correct? And once I flash that bootloader, will it still work even with my 04/13 Nightly that I have currently running? Wouldn't want flash the bootloader and not have the phone boot so I couldn't flash the newer Nightlies. Thanks for the help btw, really appreciate it!

@ Everyone
I don't have time to screw around. I just tested this and it works fine. I just would've rather bricked my device rather than yours. That's why I like to test all links for these types of things before I promote them off to you guys..
1.) Go here (above posted thread link)
2.) Put phone into download mode and then open Odin.
3.) Choose the PDA slot and then select the correct file for your device (AT&T is LK3)
4.) Hit start and wait until its finished.
5.) Done
5.) Remind me that I shouldn't be trying to do this from my phone. All it does it piss me off.

[q] gt-i317m telus (i317mvlalj2)

did some reading but didnt really find what i was looking for in this section.
i have the Note 2. v 4.1.2 but i want to downgrade to 4.1.1 so that i can unlock my device so i can use any carrier.
but then i would want to do the 4.1.2 update again completely stock from the OTA or whatever its called. and still have it permanently unlocked from the previous 4.1.1
should i use odin and a stock 4.1.1tar file for the PDA to flash it or would this be the wrong way of doing this and possibly voiding my warrenty

Well there's a few ways of doing that. The way you mentioned!
But you can also just downgrade your modem to the J2, and you can perform the unlock that way... But if unsure about what your doing, do some research..

so are you saying to only flash the modem with the I317MVLALJ2 modem and thats it... because i do know how to flash with odin. i did it with my first galaxy and for some reason the micro sd slot stopped working. so i was thinking this method would screw up my note 2. i just want to downgrade to unlock it then re update
this was the method i was going to go with. what would you say?!

Yes! :thumbup:Looks like any regular Rom flash using Odin. But I usually use Odin when flashing back to completely stock...
Another method if your rooted, like I said you can flash just the modem thru the recovery...
But I think you should do some reading on all this. Imho

I root to freeze a bunch of useless system apps. That alone is enough for me.

Rooting is only 1 part of a very large puzzle when you are talking about modification ...
Root is only a tool ...
And the real fun starts when you can build and theme or modify any number of parts inside your device ...
You don't own it unless it's rooted ...and you'll never fully enjoy it until you make the changes that unleash what these devices are capable of ...
And that starts by reading and learning ...then reading and learning more...
Then you will be on your way to making the phone truly yours ....g

4.3 Root Method/ROM Flash

I took the 4.3 (I know, I know, never take an OTA).
I want to root and flash CM11, but there is no root method for 4.3 yet.
Anyone know if there is any way to root right now (flashing 4.2 firmware or something like that) or do I have to wait? If so, how long do you think?
Thanks!

Nothing yet. All we can do is wait and see. Since there are no updates about progress that I've found from those who've posted the patches, there is no good way to estimate how long, or even if, at this point.

I haven't ever tried it, but if you're S-ON and are on 4.3 will the phone block you from flashing the old 605.15 encrypted RUU?

Afraid so. Downgrading isn't possible.

were you s off before taking 4.3
If you were then you can get root back I did it using fastboot commands because adb will not seem to work for me after the update for me if you need some help let me know

If your s-off just flash a custom recovery and superuser apk

I'm in the exact same boat, friend. Never really saw a need to unlock or root prior to the OTA but now I'm having serious battery issues, mainly the phone radio using over 50% of my battery daily. I've been googling so hard I've almost broken my internets, but can't seem to find anyway to downgrade to use rum runner. I'm just dealing with it and hoping beaups and the other devs find a way to get us unlocked. Until then I'll wait patiently with my portable charger on hand lol.

What he is saying is that if you used rumrunner or sent it in to gain S-OFF, all you would have to do is download the superuser zip file and in TWRP flash the superuser file. When you reboot you might need to update the binaries but that would do it.

No, it won't work, it prevents your from downgrading, as HTC software has always done.
If I had a locked device, there are a couple things I would try to see if I could make it work.
Likely they wouldn't though, and I'd hate to get anyone's hopes up or send them down an unsuccessful path.
Bottomline being, there is currently no way to unlock, or to downgrade from a locked 4.3 device, to achieve an unlock.

Oh yeah I've been trying. I tried multiple downloads from multiple sources but they all hang up at the checking main version action and then fail. It's pretty much just playing the waiting game for rum runner and attempting patience. I'm not too hopeful for anything in the next few weeks since everyone has been busy with Christmas and such and New Years coming up. But if it can be done, the devs on here will do it.

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.

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.

"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.
