Download the file in http://forum.xda-developers.com/showthread.php?t=2180688
Then put the adb.exe file in your windows directory.
Enable USB debugging on phone.
You should be able to get it working from there.

It depends on the recovery, but it works in TWRP.
It is the ROM that is rooted, so if you sideload a non-rooted ROM and flash it, you will lose root. It seems you don't have a working ROM, so you don't "have" root.

Let me correct you. You had a custom ROM that was rooted.
My suggestion is to fix the problem.
I can't help you because:
1) I don't know what recovery you have
2) I don't know what tutorial you followed
3) I don't know in which way it is "not working"
I suggest you flash TWRP 2.6.3.4 and use adb sideload.

You need to get adb working on your PC or you could try what bored_stupid is suggesting. You are a long why from requiring supersu at this point.

You don't even have a working rom so why are you still talking about root??? You don't need root to use a usb otg cable to flash a rom.
Make sure you have the latest android sdk installed on your computer and latest htc drivers.

It is problem globally! Google is experiencing major error with sync servers.
or try this: go to accounts.google.com and in security (left panel) go to the list of 3rd party applications that are using your Google credentials and start revoking the applications that you no longer use.

[Q] Unable to unlock bootloader of XT890: FAILED (remote: Restricted OEM command)

I'm trying to root my Motorola Razr i XT890.
First I need to unlock the bootloader (right?), so I was fallowing this thread: Unlock the Bootloader on Your RAZR i
The thread is about 2 years old, so if is there any new solution for rooting my phone, please point me to the right direction.
1. I've downloaded the USB driver and the full SDK from moto site. I've installed the USB driver and unzipped the SDK (I was not able to find any install.exe, I clicked "SDK Manager.exe" but nothing happens).
2. Config the phone to USB debug, reboot in fastboot mode, plugged to USB.
3. I opened the CMD, get into the adt-bundle-windows-x86_64-20140321\sdk\platform-tools\ where fastboot.exe and typed: fastboot oem get_unlock_data
the result is: FAILED (remote: Restricted OEM command)
Some phone data:
Version: 982.50.29.XT890.Brasil.en.BR
Kernell: 3.0.34-gf0ff387

I've never rooted a phone or anything, so please, give me detailed newbie help. Thanks in advance! :good:

Welcome.
You don´t need to unlock the bootloader to root!
If you are on JB 4.1.2 than the only you need is: "Twerk my Moto" http://forum.xda-developers.com/showthread.php?t=2541398
If you are on ICS 4.0.4 you will need "motofail2go". (second link in OP) http://forum.xda-developers.com/showthread.php?t=1928509
Hope i could help. Good luck!
Thank you for the info. So I do not need to unlock the bootloader. Nice. Anyway, this is odd that I'm not allowed to do so. Also, there is almost no info about this issue.
My Android version is 4.1.2. I followed the link you pointed and the instructions are:
To use:
adb push su /data/local/tmp/
adb push rootme.sh /data/local/tmp/
adb push TwerkMyMoto.jar /data/local/tmp/
adb shell chmod 755 /data/local/tmp/rootme.sh
adb shell /data/local/tmp/rootme.sh
adb reboot

ADB is a comandline-tool like cmd.exe, google how to use...
1. Install RAZRi drivers.
2. Enable USB-Debugging in Developer-Options on Handy.
3. Download ADB files (ADB is a comandline-tool, google how to use)
4. Extract "TwerkMyMoto.zip" (rootme.sh + SU + TwerkMyMoto.jar MUST be in same folder with ADB.exe)
5. Connect your RAZRi to PC and run ADB.exe. Check if ADB shows Handy as "device".
6. Follow the Steps "To use". (You have to copy and paste each line in the ADB-Window and execute it)
Good luck!
Thank you very much, as son as I try it I'm going to post the result here!
Yeah, it worked just fine!

To use:
...
adb shell /data/local/tmp/rootme.sh

Congrats for rooting your first device :good:
I have had a look in the source code some time ago...
something is loaded into system filesystem and needs a reboot to commit changes.
After that it needs to execute again. So thats why the line is doubled...
Did u test if root is working?
And it would be nice if you hit "Thanks" Button if i could help :cyclops:

Oh, sorry I'm new to the forum practices. Thanks button pressed! :good:

I hope this root-methode is still working after KitKat Update in the next weeks...
Now u are rooted i recommend u to enable Adobe Flash: http://forum.xda-developers.com/showthread.php?t=1952878&page=4 (last page)
And to start modding try "Xposed Framework". There u can load tons of "mods" on to your handy.
i recommend "Xposed Framework" + GravityBox + YouTube Addaway.
(maybe its better to backup your important Data befor playing around...)
And no worries that u mess up your device. If u stuck in bootloops or something else is broken just flash back your original firmware with RSD-Lite: http://forum.xda-developers.com/showthread.php?t=2239706
So, have fun with your rooted device and thanks for pressing Thanks-Button!

RSD should also work with unlocked bootloader...
And i think there was a trick to relock bootloader by flashing some files, but i dont know the files.
You have to search in this Forum for relock-tutorial ...

from my personal experiences: using RSD-Lite with unlocked BL works like a charme
And no, it will not relock your BL
To relock you can use this guide: http://forum.xda-developers.com/showpost.php?p=44430691&postcount=4
Hi there, I am having the same issue but my OS version is 4.4.2 now.
There is also a nice guide here: http://forum.xda-developers.com/showthread.php?t=1928551
But I would still need the code.....
So what do you propose I should do? I only need root so I can use a directory binding tool to make some room on the internal space, I ran out and can no longer update the apps....
(Btw. I did unlock my first RAZR, but that one broke down so now I am on an used one.. )
Thanks!

There is a problem with adb&windows 8 on almost any phone, it's not related to our phone.
I don't know a fix.
Someone mention at other post (i can't find it) that there is a utility which we can install kernel etc via our phone and don't need adb..
It is real or not? maybe i can work with it..

Owh, yes of course. You need fastboot to flash my kernel.
Okay, there are 3 options:
1. use dd, it might take you some time to learn it, but it's very useful. Just google for "Linux dd"
2. There are apps that manage the dd process for you, but I don't know if they are for our device.
3. Wait for me to make a flashable zip

What do you mean by debug? Remove Vodafone apps? Remove the update that came after inserting SIM?
If you want to remove the update that branded your device after inserting SIM, one way is by doing an factory reset and by not allowing it to do the carrier update (it will bug you to install it from time to time). Other way is by using other SIM rather than Vodafone in your device.

First of all, read my guide from here about horlw to remove apps using ABD - https://forum.xda-developers.com/hu...w-to-remove-huawei-bloatware-vog-ele-t4014937
Second, install this app and using that app you can find any Vodafone related app and remove it using ADB commands (to see it's name select app and press details).
