That worked like a charm thanks.

NEVER MIND

 

I didn't copy the CWM to the RECOVERY folder. I assumed that meant the folder you were using. Then noticed the RECOVERY folder. DOH!

Still didn't work though.

 

I think I know why though. Stay tuned...

[7eregrine]

CWM is installed now. I run the file. Reboot into Recovery. Put phone in Sideload Mode.

 

error: device not found

 

Every time.

 

Tried it on another computer, too. Win7 and WinXP. 

Copied files to C:\ROOT

Ran the Koush ADB Installer.

 

Read the instructions 30 times now, at least. I don't think you could make it any easier.

 

\\EDIT\\ Tried a fresh Download. No joy...

[SamuriHL]

It works for many others, so, you'll have to work through it.  That's definitely a diver/usb port/usb cable issue of some kind.

[7eregrine]

Are you effing kidding me? Looked at the Cable. Noticed it says LG on it. I have like 6 of these cables.

Grabbed a Moto one.

Tried it again. 

error: no device found

*sigh*

Exited Sideload. Tried it once more.

This time Windows popped up and said "New Device Found: Galaxy ADB drive".... First time I've seen that.

Hmmm. Back into Sideload, run RUN.BAT.....

 

Success.

 

The. Freaking. Cable....

 

Wow.

 

THanks for the help. What have we learned today?

• COPY the CWM IMG file into the directory that gets created when you unzip called "Recovery"
• Use a GD Motorola Cable. Period.

[SamuriHL]

And people give me a hard time when I say "use the oem cable that came with the phone....yes it matters".  LOL  Glad you fixed it.

[johnthehillbilly]

As Sam continually says..... Use a MOTOROLA cable..... Makes a huge difference!!!!!!....:) Glad its working for you now!!!:)

I've seen this happen as well. Not all USB cables are made equal. You would THINK they would, but I think it depends on various things, including how much power can it feed to the phone.

 

My daughters have a blue-tooth speaker that is shower-safe that they use to hook up to their iPhones to listen to music. It comes with what looks like a standard USB cable that has the exact same connector that fits into my USB port of my phone. Hook it up to the PC and nothing. Hook it up to an outlet adapter and nothing. It won't charge.

 

But, it has no problem charging the blue-tooth speaker. More than likely, it probably doesn't require as much "juice" to charge the speaker, so it probably doesn't send the same amount of voltage through the cable.

I have definitely seen LG cables for older LG phones that I have not work with my Android phones and I would happen to guess it is the same reason as it is with the blue-tooth cable - it doesn't supply enough current to charge, let alone, allow it to connect to a PC and register itself as a device you can adb/fastboot to.

Decided to take the plunge.. Thank you for the great write-up it was easy to follow and the only tricky was getting into fastboot, but that's explains in a later post.  Now time for me to get root back.  BTW, I was on 4.4.2 with an unlocked BL before the update script and everything went smoothly!

[SSpinball]

started with a fumbled OTA. on my xt926  dead Android, no boot.bricked

finally found this tool, fumbled thru it for 2 days,

almost ready to give up, somehow, some way finally used the universal file, with RDS.

it starts Flashing  Yeaa !! , reloaded the new VXZ. 

 

Thank you very much for developing this work !

 

Love my Maxx phone, ... on GSM  ... Tmobile

I was having problems with this on my unlocked XT926 with the latest KK update.  Namely, no many how many times I tried, I always got "<bootloader> Variable not supported!".  What finally worked:

 

1)  Installed the latest Moto drivers from Moto themselves (

)

-> this was a key, the Koush Universal ADB driver was failing.  Whenever I'd connect my phone in ADB mode to my Win7 x64 machine with just that driver, Windows would fail to install a driver.

-> also made sure that I had Developer enabled on my phone (update wiped it) and enabled installing apps from unknown sources

2)  I copied the SuperUser update zip to my phone's external SD card.

3)  I copied the CWM img file to my C: drive, and renamed it to "recovery.img"

4)  I opened a cmd window in windows (Start->in run field type "cmd")

5)  In cmd window, typed "cd c:\"

6)  In cmd window, typed "adb reboot bootloader"

7)  In cmd window, typed "fastboot flash recovery recovery.img"

8)  I repeated that a good half dozen times or so, always getting the same "Variable not supported" error but it appeared to copy.

9)  In cmd window, typed "fastboot reboot"

-> I think this was also key for some reason, rebooting phone normally once after installing CWM.

-> disconnected phone until it finished booting, then reconnected

10)  In cmd window, typed "adb reboot recovery"

11)  It finally booted into CWM!  Then I just installed ZIP from external SD card like normal.

 

Hope this helps someone else struggling.  I have no idea why that finally worked despite getting the same error message, but it did.  I was using a Moto USB cable the whole time, and used the same USB2 port on my laptop the whole time.

o) IF you need to have custom recovery installed for you, add your twrp OR cwm recovery img file to the recovery folder.  This is ONLY necessary if you don't already have custom recovery flashed to your phone.

 

Thanks for providing this information.  I appreciate it.

 

I'm working to restore root on a Droid RAZR MAXX HD recently upgraded to 4.4.2

The phone is unlocked and was purchased used.

How do I determine if I have custom recovery on my phone already?

[SamuriHL]

Did you install custom recovery? If you didn't then there isn't.

I didn't but it is possible the prior owner did.  It was unlocked when I bought it.

[SamuriHL]

Did it come with 4.4.2 when you bought it?

[jtelander]

Nope, installed last night using your instructions. Now trying to root using only your instructions. Thanks

Then when you updated it put stock recovery on the device. Your only option at the moment is the Cwm built for KK on the HD. Sent from my S-Offed One M8
