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.

I've been wanting to take the ota kit Kat version but scared if I take it I will loose root and my flash to Pageplus with 3g and mms working. have anyone took the update and still able to gain root access and Pageplus service with working 3g and mms?

You will lose root, unless you are bootloader unlocked then you can flash su easily. No idea about Pageplus service, depends how you enabled it originally..

So is it possible to unlock my bootloader then take the ota update.

You can't unlock your bootloader unless you have a dev device or XT925..if you don't have either of these then you'll have to wait until there is a method to keep root (if it's possible).

Not entirely true. It you are on an XT926 non-dev device, you could still unlock the bootloader IF you haven't upgraded to any OTAs after version 9.16.6. If you've updated it via an OTA since that version, then no, you cannot unlock your bootloader. And downgrading back to 9.16.6 will not fix it. Once the OTA is applied, the exploit to unlock an XT926 is gone forever. It was the one and only chance of unlocking the phone. No other options exist unless Verizon allows it to be unlocked via the Motorola unlocker program, which I highly doubt will occur.
If you are still on 9.16.9 or earlier, then you can go here and try to unlock your bootloader -> http://vulnfactory.org/blog/2013/04/08/motorola-bootloader-unlocking/
You must be rooted in order to do this.
If you are on any of these versions, then you can no longer unlock your bootloader:
9.18.X
9.20.1
9.30.1
183.46.10 (KitKat)
Trying won't hurt anything. Worse comes to worse, you'll still have a locked bootloader. Best case scenario, you'll have an unlocked bootloader!
We've already had one success story since the OTA with a user who was able to unlock his bootloader, so you might be the same as long as you are on the version stated or earlier. He was and luckily, no later OTAs were applied, so he's now unlocked.

[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

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...

You can't. Period.
Should have researched. Your phone may very possibly brick when you take the next update.
Downgrading is a no-no. Not possible.

Motorola signs OTA packages. The signature check fails because Moto simply doesn't want us downgrading.

I think, and I hope to get corrected if I'm not accurate, that downgrade is possible as long as bootloader stays the same version. Once the bootloader is upgraded, downgrading OS to a lover level will not be possible. Bootlader can remain the same version through multiple OS upgrades.

U can research for taobao boot loader unlock and that will allow you to unlock boot loader and gain root . but not a 100% sure thing but will cost ya 45 bucks if successful.
