If you're on system version 9.18.79, unfortunately, currently there is no known method to unlock the bootloader for XT926.

Root and still getting OTA updates theory

Hi XDA-Devvers,
In a topic (http://forum.xda-developers.com/showthread.php?t=1510719) I read about the following:
Nonverbose said:
Root won't stop an ota but an unlocked bootloader will. You can check in your boot screen if its still unlocked or if its relocked.

Doesn't that mean that we can root our tablet, lock the bootloader again (fastboot oem lock), install Voodoo OTA RootKeeper and once there's an OTA available, just backup the root with the Voodoo app and install it?
How awesome would that be :laugh:
Since I am not a pro in that kind of stuff: Can anyone confirm this theory might actually work for real?
fastboot oem lock is unavailable once you unlocked the bootloader.
Ah bummer. Can we relock the bootloader yet? IF we were able to relock the bootloader, it would work, wouldn't it?

No, as many informations -including bootloader version- are sent to check if a new OTA is available

Okay, thank you for replying. This makes the decision to root a little harder since I want to keep getting updates and for that you'll need ClockWork (and the people who are pushing the update to XDA)(Clockwork does have the nandroid backup though, which I want to have when rooting), which doesn't run very stable last time I read (I rooted before, but then I sent my tab back (heat problems) and got a new one. I flashed a beta ROM xd).
I thanked your post
Isn't it enough to have the original Kernel and ROM? Do you really need a locked bootloader to get OTA updates?
Has anyone tested the universal root method? See http://forum.xda-developers.com/showthread.php?t=1886460
As this doesn't effect the Kernel, OTA updates might work if rooting works with this method.
I've not tried it. I've read some people are bricking their tablets with the universal, and since the A700 is basically a brick waiting to happen, I think I'll pass on it for a while.

[Q]Might buy this instead.

I might be buying this instead of the M. But first, some questions.
1. When I first get it, will I be able to unlock and root it straight out of the box, with or without OTA update?
2. How good is the dev support for this phone?
I'll update this when I think of more.
Yes you can unlock the bootloader and root and and flash a recovery. And about Dev support well we just got official CM10.1 and PAC and alot of other roms.

Um, no, you can't unlock the bootloader anymore on the latest OTA. You can still get root by downgrading to a previous firmware and using Voodoo to protect root before upgrading again, but you will never be able to unlock the bootloader since the trusted zone partition can't be downgraded.

So don't OTA when I first get it?
I mean, I'm fine with a non-unlockable bootloader. But if I have the choice to unlock it when it comes in, I won't be OTA-ing it. Speaking of which, whenever you activate the phone, doesn't it OTA?
Also, whenever I receive this what version will it be running on? And what version did they patch the bootloader method you guys were using? I'm not gonna be OTAing. And if activating the phone means OTAing, I'll unlock it prior to activation.
What you'll more than likely get from Verizon is a phone running the 4.1.2 firmware, build number starts with 9.16. This will be rootable, but you will not be able to unlock the bootloader. You will be asked to update with an OTA to firmware build number which starts with 9.18. You won't be able to root 9.18, but if you root on 9.16 first, use VooDoo OTA rootkeeper and then update, you should still be rooted on 9.18

So anything before 9.16 and I should be good to go? Hopefully they don't ship it out with 9.16+
Actually, would it be possible to downgrade to below 9.16 whenever I get it?

[Q] XT926 4.4.2 Questions.

what information do we have on rooting after the 4.4.2 ota update? Also is there any information on unlocking the bootloader? I'm trying to see what other people have tried before I keep going at the same things that have failed. Also is there any information on changing the imei/flashing this? My end goal is cyanogenmod on Virgin Mobile. I've done this with other phones and I just got my hands on this one but there doesn't seem to be as much into on this as others.

****. So I'm holding an unrootable piece of crap? What information do we have on methods of root attempted and such. Maybe I can contribute to this I've got nothing but time.
Edit: your thread unlocks gsm support. VM would probably need me to reprovision everything and change my IMei to match a donor phone.
I've been attempting various root methods for 4.4.2 and for the RAZR in general. I've had no luck. Is there a collective of people working on this cause I'd love to contribute however I can.

Just as an FYI, that is called "lambda" which is a greek symbol.
Also, this works on 183.46.10 (the current KK ota that came out a few months back), but it does NOT work with the latest soak test (183.46.14), so you need to stay on 183.46.10, root with towelroot and then unlock your bootloader. If you do not do this AND if you take the soak test, you will be unable to root as a root exploit for 183.46.14 does not exist.
I don't want to say it won't ever be rooted, but as more and more exploits are patched up, it becomes harder and harder to root this phone, so your best bet is to root and unlock the bootloader on 183.46.10. Don't take the chance on whether a root exploit will be found or not. You'll save yourself, and the rest of us, a lot of headaches.
If you have already applied the 183.46.14 before rooting and unlocking your bootloader, you are SOL. There is NO way to go back to the previous version and root and unlock, so please do NOT ask how to revert back from the current soak test (183.46.14) and root and unlock your bootloader because you can't. You just can't, so don't ask.
I repeated what I just said because people always ask "well, if you flash back to 183.46.10". The problem is, the exploit that allowed unlocking of the bootloader is in a protected area that even unlocked bootloaders cannot write to without the proper encrytion keys. Once that area has been patched via the latest soak test, you have no way to write over it again because you would need the proper encryption key inside the image to flash in order for it to work. Unless Motorola becomes nice and gives you the key, it won't work. And the previous OTA's key is now invalid, so again, flashing the previous FXZ (183.46.10) will not work. It will just skip writing the protect area.
Clear as mud? Hopefully.
thats lambda....but you knew that

[Q] Downgrade KK to JB with locked bootloader (Razr XT926)?

Is it possible downgrade from KK to JB with unlocked bootloader
by the House of Moto and proper XML file?

Yes.
But, here's something even better. With the new Towelroot for locked bootloaders on KK, once rooted, you can then use Motopocalypse and unlock your bootloader.
Nice going, Motorola! With the KK update, someone must have pulled in the old code to allow the exploit to unlock the bootloader (that was patched as of 9.18) to work. Way too funny, but I'm sure many people out there are bowing to Motorola for this, even though I'm sure it wasn't supposed to happen like this! :silly:
So, those of you with locked bootloaders, go root RIGHT NOW and UNLOCK those bootloaders. You're warranty was voided as soon as you rooted, so what harm is there in unlocking it as well? That means when the next OTA comes out (not sure when, but it will probably be soon since I got a new email for a new soak test), it means root will definitely be broken for those with locked bootloaders. With an unlocked bootloader, you'll be able to sideload SU onto your phones when the new OTA comes out, so better to be safe than sorry.
Good to know...

Well, technically there is no going back.....you can use SamuriHL's HouseOfMoto...with the JB FXZ files to generate the scripts, and then use the Universal script to flash....this will flash everything EXCEPT the tz and gpt partitions, at that point you should be able to flash a JB ROM.
You cannot downgrade tz and gpt so dont waste your time trying...

[Q] Is there any way I can root with 183.46.15?

I didn't know that there was a root workaround found for 183.46.10 so I foolishly updated to 183.46.15. I've had this phone since 4.1.2 so will a factory reset take me back to 4.1.2? Otherwise will RSD Lite help me? (I'm really sorry for being so ignorant about these things and asking questions that I'm sure are dumb)

Unless you unlocked your bootloader, you have NO way to go back to a previous version nor can you root. There is no way to unlock the bootloader once you've taken to .15 OTA.
Sorry to be the bearer of bad news, but once you took the .15 OTA, you lost all access to root and unlock the bootloader. There is no going back. Your only hope is if someone discovers a new security flaw that can be exploited to gain root access, but since this is a 2-year-old phone, I wouldn't hold my breath.

What if I accidentally updated to 183.46.15 but my bootloader is unlocked? I was fully rooted with unlock on the 4.1.2 bootloader, but wanted to update so I could flash the new CM11 builds, but I too foolishly took the .15 OTA after installing .10. I just can't seem to find a way to roll back to .10 or flash a recovery now...

You're fine. Once unlocked, always unlocked. Just flash root and you're good to go.
The unlocking of the bootloader on this phone is a physical change, not a software change. Basically, something called an efuse was blown. Hence just like with the old fashioned fuses from a long time ago in a house far far away, once they blow, you have to physically take them out and replace them with a new one. In the case of the phone, you can't really do that without putting in an entirely new motherboard. Hence, once unlocked, always unlocked. They can't lock it back up since it was a physical change on the phone itself.

As long as your bootloader is unlocked, yes. Then, you can flash root.
You need to use the correct recovery that is based on the KK bootloader.
Most are using TWRP as their custom recovery. You can get it here:
http://forum.xda-developers.com/showpost.php?p=53245455&postcount=1
Flash that and then boot into recovery and flash the latest SuperSU:

Is there a way to know if I have boot loader unlocked ?
boot into fastboot, read message displayed on your screen
