Does using it require an unlocked bootloader, and will it unlock the bootloader in the process?
Trying to help my friend root so he can back everything up, then unlock his bootloader.

For T999, if its on 4.2.1 or prior version of Android, then the bootloader is unlocked. If its on 4.3, the bootloader is locked and there is absolutely no known way to unlock it.

And that would mean there's no way to root on 4.3 if my friend is already there, correct?

Hmmm.............. Well, not quiet. But the problem is, you may trip that dreaded warranty bit. Visit the Root66 Thread and flash that image UVUEMJC.

Would flashing the 4.3 from that thread lock the bootloader? I don't think it will, but just want to be safe.

Since the phone is already locked, that Rom won't re-lock it. It won't unlock either. That's why I recommended that Rom (UVUEMJC). If you tried prior Root66 roms, you will brick the phone.

His phone is on 4.1.2 so the bootloader should be unlocked. If he were to flash the Root66 4.3 would it lock the bootloader?

Do not flash the root66.. instead flash a custom recovery with Odin and then flash a stock rom and update modem if you're gonna flash 4.3.. that is the safest to do it if your friend cares about warranty.. you can still flash the root66 and it will be rooted but it may trip the warranty bit, I'm not too sure

I'm fairly sure his warranty is up unless it's lifetime, because he's had it for 2 years. Either way, I was just checking in case he decided to, I think he just wants to root 4.1.2 and stick with that for now.
OK then just use cf auto root.. It even works with 4.3 so no need to worry about bootloaders or anything

hello people
its possible downgrade from UCDMG2 4.1.2 to UCDLK3, no brick the phone?
thanks
Which phone do you have? Try and find the 4.1.1 firmware on samfirmware and should be able to downgrade using Odin.
Downgrading always had its risks.

I have the i747, but had heard that has the locked bootloader and why I have not ariesgado.
The locked bootloader and knox came with stock 4.3 ROMs.
If you have never had stock 4.3 ROM on your phone, you can downgrade to 4.1.1 to unlock your phone, but there may be no stock 4.1.1 ROM for your phone, depending on your carrier.

hello, is to try to unlock the free.
Thanks for answering
You should be able to downgrade as long as you have never has your bootloader upgraded to 4.3 and you find the right 4.1.1 file.
I want to Downgrade 4.3 to Stock 4.1.2
Is there any way to do thtat
because now Knox bootloader wont allow Downgrade

The first thing is DO NOT TRY TO DWONGRADE THE 4.3 BOOTLOADER. You can Brick your Device. If you want to root the device. Check out the thread HERE.
Thanks bro

As far as we have tested, after flashing complete firmware ND3 it is possible to run 4.3 custom roms (not tested older ones).
Regarding wifi and similar issues it is advantageous to have newest firmware including bootloader.

Which 4.3 firmware have you successfully flashed? Are all 4.3 firmwares working on ND3 bootloaders? I don't plan on going back to 4.3 but want to know for my knowledge Thank you

We only tested 4.3 custom roms, no firmware and depending on Knox status, in my opinion it could be possible to downgrade firmware to any 4.3 with knox enabled BL, as long as Knox isn't triggered. That's only theory and for me too late to test it. Never cared about warranty.
I have a silly doubt.. How can the Knox counter trip if we use Custom ROM without knox?
Above is valid if someone want to upgrade from MJ5 Bootloader to newer one with any new custom rom.

There is a difference between Knox app and Knox counter in the download menu of the phone. Once you go up/changing bootloader from mj5 then you get a present Knox counter for free.
Any custom room using higher bootloader will set up the Knox.
It's not about it is custom or not it's about flashing the bootloader.

Got it.. Thanks..
hi, I just recently aquired the Nexus 7 2013 model, and I am currently not rooted. I want to root but I dont want to run CM or all the other custom roms. I just want a stock rooted rom.
Is there a stock rooted 4.4.2 rom for this device?
That is all, thanks!
There is one here: http://forum.xda-developers.com/showthread.php?t=2563017
You will need a custom recovery in order to flash it!
Or you can just flash the SuperSU zip in recovery and it'll be rooted

You will need to unlock the bootloader first before flashing a root zip. Then you will have a stock rooted ROM. http://m.youtube.com/watch?v=XM3CBtAaoWU

I'm curious. I've never used a device with a locked bootloader. Since this tablet is about to get the 4.4.3 update, will unlocking the bootloader affect the update? Will I still receive the update.
I'm planning on unlocking the bootloader but not flashing the rootzip yet until I get the update.

Yes, you will still receive the OTA. Having an unlocked bootloader has no effect on updating via OTA.
You could just root and then re-lock the bootloader

That won't work. If you relock the bootloader everything has to be stock.
It would just refuse to lock

Only recovery needs to be stock to relock the bootloader, you can unlock, root and then relock - then you have rooted stock ROM and a locked bootloader without having to flash a custom recovery or ROM.

Are you sure? This wasn't the case with my Motorola Xoom. I thought everything needs to be stock, wouldn't this defeat the point of relocking since its meant to be factory settings for warranty purposes?

Have done it on both my N7 and N5 - does provide a small measure of security for the phone (my company allows rooted devices, but only with locked bootloaders) see http://forum.xda-developers.com/galaxy-nexus/help/info-understanding-risks-unlocked-t1898664
after rooting - fastboot oem lock

fair enough, I stand corrected! Didn't know you could re-lock a rooted device.
So could you flash OmniROM, flash stock recovery and re-lock?

From what I understand, yes, that is correct - although I have heard that some ROMs require a custom recovery

My phone has mjb modem I tried the method which is confirmed working in 4.1.1 but in 4.3 it seems not to work... Phone is rooted. Any advice? When ever I insert an other not supported sim it says no sim inserted. I have sr3x rom.

Your success in using the free unlock would appear to depend on which bootloader is installed on your phone.
If you have the MJB bootloader you are most likely out of luck. If you have the MJ2 bootloader it is probably possible. I reference this post found in one of the unlock threads:

Thanks, so it seems I am out of luck since my phone once had bricked and I unbricked with full mjb firmware... My modem and bootloader is mjb... No free unlock working with that.

Once updated to 4.3 (MJB), you cannot downgrade, even just the modem. The requirement for the free unlock is the 4.1.1 modem, and since it won't work, you can't do the unlock.
The only way I know of is by using an unlock code either from AT&T or one bought online. Sorry.

Yeah I thought that it would be like that. Thanks. I do not need to unlock it anyways, I solved the problem which wanted me to change carrier.
