I have a wifi Xoom only have tried to root after unlock several times seems my Xoom after its unlocked, restarted automatically.Never able to connect to xoom from manual bootloader and now stuck at moto logo i've tried this but http://forum.xda-developers.com/showthread.php?t=1097997 but in the instructions i am posting:
Okay here we go....
first thing let your xoom stuck on M logo.
Then hold power+volume up.
while power up press volume down to get firstboot.(make sure your PC and xoom know each other.)
You will see some text firstboot bla bla bla on left, top of screen.
At this point where pc and xoom commicate, Mine dont not make connectivity. This has been my problem all along the pc sees it when its loaded the i put it into bootloader still ok try to flash something , then restart no connectivity and Now it is stuck at the moto logo with no connectivity to the PC and yes it is plugged into the usb. Now i have no reboot. I have access to the stock android recovery only dont have the camera cable yet either. Sorry about being all over the placejust wanted to get all my facts out there.

Hi
After being on numerous custom Roms for the xoom I decided to return to stock and was succesful in return to the 3.01 stock image for the wifi MZ604 model
I was also successful in relocking the xoom.
I then began to receive the offical updates though everytime the were applied I had to go into recovery and wipe the device as otherwise it would bootloop on the dual core screen.
On the last update that it received and that was installed , on rebooting nothing happend and the screen just went blank
No combination of volume up + power would show any sign of doing anything.
After leaving the tablet to the side for awhile I noticed it came up with the following
model mz604 : Revision0 (0x8000) modem none
InitBl Info function failed with codes 299/3
failed to boot 0x0001
starting RSD mode 3
one wire : charger is not connected or battery is not being charged
battery charge level : 56%
I tried fastbooting and adb at this point but no devices are found. However when plugging in the xoom my laptop recognises something is attached.
After some searching I found out about RSd lite and SBF files.
When opening rsdlite v5.6 (running as admin) the tablet is recognised and I have now attempted to use two sbf files
HUBWF_W5.H.6.4-20_SIGNED_UCAHUBLWFRTCOREEU_P010_A010_M004_HWwifi_hubble_AP1FF.sb f
and
HUBWF_W5.H.6.2-24_SIGNED_UCAHUBLWFRTCOREEU_P006_A006_M003_HWwifi_hubble_Service1 FF.sbf
however both fail when it attempts re numeration.
I would greatly appreciate any help that anyone could give on this
Thanks
Try this.
My mom's Xoom had a similar problem. Reboot the tablet by pressing Volume Up and Power.
Then quickly turn on the xoom and press the down button as fast as possible, and continue pressing until you see "Recovery Mode" (or something similar) on the top left of the screen.
Once you see that, press the volume up button. Quickly, when you see the Android guy with the exclamation mark tap the power button and the up button.
This will take you to recovery mode. In there use the up and down volume keys to navigate and the power button to confirm things.
Go down to restore/delete data (may vary) and press power. use the volume down key to scroll to Yes.
This will restore your tablet back to factory settings. If you're trying to backup your data, don't try... No such luck and you won't be able to without the tablet booted.
thanks for the reply but this didnt work. Tried quite a few times. The screen just goes blank and again after a long while the error shown in the op appears. Should add there is no Motorola logo showing.
I have also tried forcing fastboot by the instructions found in other similar threads but again this does not work.
I think my best bet is the SBF files , but need to understand why this is failing on re-numeration
xoom stucked on boot logo - none of the buttons work in my old xoom
the power button works but you have to press it from every direction,
both volume buttons dont work
to turn off the xoom I need to disconnect battery so hard reset Power button + Volume won't work
I updated CM 10.1 with the last update and noticed that the 3G doesn't work as good as before so I reverted to previous version and it sucked on the logo
please share your ideas on how to bring the old xoom back alive ?
tried rebooting with and without SIM card in , and SD, no luck still at the logo .
I am going home now so if you can think of how can I restore the tablet with SDK ( if its possible ? ) please drop me a line on how to do it
...managed to install SDK tools and connected xoom to laptop,
but when type : adb reboot recovery , the error I am getting is :
"error: device is offline"
is there any chance to bring it back to live ? please say YES !
Hello guy's i'm new too this site, My moto G has been suffering problems since i installed kitkat . .
I then reinstalled it to stock rom and it was the wrong version, it was for an EE phone were as mine is actually unlocked.
my phone lights up once with the moto g sign when i turn it on and i have seconds to get it into bootloader mode via wallplug.
The problem is i need my bootloader to show on my phones screen when i plug it in the pc but it comes up for like a second and a half then goes off. I have read nearly all these forums and theres not alot i can see about this type of problem so please somebody help.
Also if i get bootloader on the screen via wall plug and try disconnecting to plug in pc it just goes off also. Stuck humm :I(

So, when you press Power + Vol down while connected to a computer nothing happens?
Doesn't make sense that you can only get into download mode when plugged on a wallplug.
How about when you are not plugged in at all? Can you still get into download mode??

Nope only with power to it, so if i try bootload it with no power phone will just stay dead and wont register. When i put in the pc and try vol + and power bootloader just flashes on and off once and phone dies so at this point im erm f**ked?
:crying:

Hmmm.. Unless you can get into download mode, I'm afraid you are out of luck...
What exactly did you do when you flashed the "stock version for the EE phone? (what does EE mean?)
I don't understand how a ROM for the Moto G can screw up download mode...
Maybe you can try this... http://forum.xda-developers.com/showthread.php?t=2623587
I guess this only works if you have a Moto G that don't want to power on and if you plug in a pc is recognized like "qhsusb_bulk"..
Be sure to read the thread carefully...
And adb doesn't work?
Code:
adb reboot-bootloader
Maybe you need to let it charge, or your battery simply died.... try using a factory cable
If you can reach Bootloader (even in a wallplug) the Bloader isn't failing...
Sounds like a electrical problem
I received an Acer A700 from friend and here is the story;
He started getting the boot loop issue, Acer logo and reboot, etc...
He got into factory reset mode, and attempted a factory reset, during the process, it froze on "formating" and he attempted to shutdown the tablet. After he shut down, the tablet no longer does anything! Power LED only comes on during charging, and no beeps, no vibrate, no screen, just black. I have tried to use the usb connector to connect to my PC, but the device shows up as an APX device, but drivers fail to load, and then the device disappears. I have tried to install the latest usb driver from Acer, but no luck. I have the same tablet and I use CM and would like to get him moved over to that if possible! Any one has any suggestions, or is he bricked?
Thanks

If he's booting in APX mode, (black screen, PWR lite on, and seeing it shows up as an APX device), he's pretty well bricked. Problem is, it takes NVFlash to flash the proper files in that mode, and unfortunately also and SBK (Secure Bootloader Key) which Acer refuses to give us.
He can try doing a manual data erase (there's a post sticky on key combinations in the forums that explain how. )
If he can get it into fastboot somehow, it's possible to erase some of the partitions. Might help.
Heres the link for some manual modes. Note that some of them changed from ICS to JB, so might help to read all the posts. If he can get to fastboot, it would help a little.
Hi guys, I have a Moto G 1stGeneration. I followed the unroot guide at the unlockr.com (can't link it due to my newb status on these forums). And I was pretty much at the end of the process, then rebooted after flashing the TWRP Recovery. But then the 'WARNING BOOTLOADER UNLOCKED SCREEN' appeared... and now it won't go away. I can't even get into fastboot mode with Power + Vol Down. It just shuts off the Moto G fo a second, then the screen reappears. I dun goofed. I didn't clear the cache before reboot. I can't even connect the phone to my PC anymore (it isn't detected at all). I can't even just shut down the device. It just boots back up. Like it's giving me the finger. I'm ready to just wipe out the phone, then start over. But I have no idea how since I can't get into recovery mode at all. If I manage to shut it off, the warning screen reappears. Can't escape it. Any suggestions?
