Hey everyone. So I have installed the OTA Jelly Bean update (4.1.2) on my XT912 and I want to go to ICS so I can have root and maybe try OTA RootKeeper. I know it "can't be possible" to downgrade, but there's one idea I have. In ICS, **I created an "update.zip" file. This was basically a backup of all my things... Can I use "update.zip" to downgrade my phone from Jelly Bean to ICS?** Thanks. :laugh:

Anyone?? I don't need a real answer. At least a prediction.
My prediction is that it won't work due to the locked bootloader hence the kernel will stay jellybean kernel

Yeah that sounds correct. I just need to wait for a root method I guess... thanks. Hurry up with that root method, ppl!

You can keep waiting. Ill see the s4 and s5 before i see an unlocked bootloader for the razr. By which ppl with razrs will move on to another phone

Its not possible! If you try you will brick due to the fast boot files being different sorry bud

I've noticed while flashing back that it fails on boot but everything else passes... Has anyone else experienced this? Is anyone working on a fix? Or perhaps rooting while on jelly bean? Cause some of us weren't fortunate to keep our root...

You can't flash back, and there is no rooting JB yet.

Motorola If you want to know more, read about CDT aka cdt.bin.
Your razr is xt910 pra xt912?
Its RAZR maxx
If I remember correctly, the issue is the cdt.bin file. It's like the encrypted security file for the bootloader. They updated this file on the .84 ICS leak to start, which is how most people got stuck on it.
This cdt.bin file was updated again with this Jelly Bean leak. Meaning that there will be absolutely no way to go from Jelly Bean back to ICS. Someday we may get JB fastboot files, but you're not getting back to ICS as long as this phone has a locked bootloader.
I do not know if this has been posted already but there is root for Droid Razr running 4.1.2

Yes, there's a thread for it somewhere around here, personally I would either try the dual boot option, or wait for the official ota, judging by the accidental leak I would assume they are working hard to push the official soon.

I can confirm this works with the OFFICIAL 4.1.2 release (not the December 24th one). Also, I didn't do a FDR. I DID enable the stock apps I disabled though. Also, when you unzip the root exploit zip file, do not rename the folder it creates. I kept running into an issue of it not working, until i just unzipped and ran the .bat file. It worked smooth after that. I was running .211 when I installed the OTA final update today, to clarify.

How do I know this version gives the right to an root?,
XT910 EMEA 4.1.2 Root ?
Getting ready to do my very first root on my Razr Maxx XT912.
Currently running 4.0.4
Should I OTA to JB then root, or root from ICS or does it really matter?
Any benefits or downsides to either?
Thanks,
Jeff

You might get more support on XDA if you stay on ICS, esp if the jb OTA just came online. I personally don't think there's all that much benefit, you can always do your prl, profile, update, once you root anyway. But if you want to flash a custom jb ROM, all the ones I've flashed require you to flash a stock one first. Then if that's the case, then yeah, def ota to jb so you have it already when you flag a custom jb.good luck. Read read read before you root!

Well went to JB before root. Then found out they did away with speed dial. I loved speed dial! Anyway everything works out great. Thanks those that replied.

I updated my razr xt910 to jellybean 672.180.41.XT910.Retail.en.EU yesterday and I'm searching for how to root it.
I tried this root program found at the following link but unlucky, without success.
http://www.droidrzr.com/index.php/t...ows-razr-blade-droid-razr-41-jb-root-exploit/
Apparently this program maybe for xt912 only.
Is there anyone who did successfully root xt910 jellybean EU?
Thanks for reading my post.

Are you really on jelly bean looks like your still on gb... If your really on jb then there is no known way to get root access at the moment for xt910...

I could only confirm, that if you already updated to JB then "there is no known way to get root access at the moment" for European XT910 :/

someone should make a backup with a protected root in the app and share the backup file then restore the app and also the root

No, this is not possible, because you need root to backup root, and you can't restore it from other device to yours, you don't have such permissions on your device.

why is this one so large and what i ssafestrap? the ics root i used was only a 7mb download.
Safestrap is for making a recovery backup, and flashing etc. its like a multi tool you can also flash roms with it.
That's always been the size?

Yeah use the one the other guy gave you, its large because it has allot of things you need, such as flash factory files, root, install ota keeper, and safestrap which lets you install roms. Its a really good utility, and its the only way you can get root on JB.
