Oh man. I was trying to root my Xoom and followed the directions here: http://wiki.cyanogenmod.org/wiki/Motorola_Xoom_(Wi-Fi):_Full_Update_Guide#Method_via_ROM_Manager
I pushed the vol - button with the power button and got "starting fastboot support" with the Red M logo.
I opened a cmd window in win 7 and got to the ADB folder and did the "ADB devices" command.
It didn't list my Xoom so i looked down and the screen was black so i unplugged it and tried to restart but it won't start...nothing...nada...zip.
Have I bricked it?
EDITED TO ADD: i found the problem...it just ran out of battery. I plugged it in and it's fine.
Word of advice, NEVER do anything to your device(s) without a fully charged or at the minimum 70% battery, just incase things get fubar'd.

Well I use this tool daily to test it out and have never had this problem. Make sure you did not hit the 3G Root button because if you did you have just became an owner of a awesome mirror.
Always look to see that you have hit WiFi.
Now if it only got to the fastboot OEM unlock then do this.
Make sure your XOOM was plugged in and charged, if not this WILL brick your device because it is formatting it and if it stops before the format is complete your screwed.
If your device was plugged in, try holding the power button for a few seconds and see if it does turn on. Chances are you may just be hitting the button in which case a red light will plash at the top and that is all.
Once that is done post your results on here.
its been fixed. PHEW. Had to hold down power and up key for 3 seconds, in case anyone has a similar problem.
I'm new to Xoom but gave unlocking and rooting a go. That was todays mistake! I flashed a 3g version of boot.img. Then I tried to flash back to stock img-file. Found out that it also was a 3g img-file. Flashed once more. Now it was a wifi-only boot.img. Now I'm stuck at the Motorola Dual Core logo with Starting RSD mode 3 written in top left corner. I can't shut this thing off or anything else but rebooting back to same screen. I really don't know what to do. I bought it yesterday from a man that bought it in the US a week ago so I can't go to the shop and I don't think there are any shop that can flash it for me because it's not available here in Sweden yet. Please help. I have RSD Lite installed and the correct drivers for the Xoom installed. I'm used to ADB but it can't find the device and fastboot doesn't see it either.
Edit. I can't go into fastboot mode.
Grab the wifi's boot.img off of here:

This might be helpful. Not sure.
Don't worry you are in good company, even BRD had the same problem. Here's how he fixed it:
While I was in "RSD Mode 3" I did
Code:
fastboot flash boot boot.img
Even though there was no response from the device, I pressed Vol Down + power until the screen went black. I then quickly pressed and held Vol Up + power. The device then went into the bootloader, received the queued command from fastboot, and flashed the boot.img. Finally, I did
Code:
fastboot reboot
and was back in the game.
Guys, I think the moral of the story is to slow down and be careful with fastboot. You can bet i'll be a little more careful

Edit: Same advice as linked above by milehighclubAV8R
That doesn't do it. Propably it's some stupid misstake from me but I cannot do this because of " I pressed Vol Down + power until the screen went black". It wont get black. When I press Power + Vol down nothing happens. Am I doing something wrong. I have tried holding the buttons for about 30 seconds and nothing happens.
Did you just press the buttons or did you also enter the fastboot code as suggested?
First cmd command then pressing the buttons. When I reboot using power + vol up it starts into RSD mode 3. When rebooting it with power + vol up then vol down when black it starts into the logo screen without any text in the upper left corner. Can't even shut it down with long press on power button
Can I pull the battery? On my Galaxy S that's the way out if I get in a boot loop or need to redo a failed flash.
Not AFAIK, the unit is sealed and can't access the battery to pull it.
Perhaps ask in this thread - http://forum.xda-developers.com/showthread.php?t=973355, there may be more technical people seeing it there than in the general section.
OK. I will do that. Thank you for trying to help.
Press power+volume up. Hold it til it restarts. Let go of both buttons once you see the motorola logo then just press volume down once, and you should be then able to cycle through 3 different modes. Press volume down to cycle to different modes, volume up to select. Hope that helps.
Sent from my Xoom using XDA Premium App
Sorry but I can't cycle through anything. There are two modes. Either "Starting RSD mode 3" or nothing and RSDLite can't communicate with it so I belive that my xoom is dead. Sending it in for repair tomorrow. I'm giving up.
mine is stuck in the rsd mode 2. if i push and power and the up it will boot cycle if i the down button it says it is the the flashboot protocol mode, but i cannot get it to respond from the cmd window. my computer doesnt think its connected. i have the correct mot drivers. any help or is it bricked
Some people have been getting lucky with ADB commands however others have not been so luck. I myself am in the others category with one of my XOOMS.
Sucks, but some people have been able to get back. I however have not been so lucky with one of the WiFi XOOM's I have and did this purposely to see if maybe something can be done with it. Looks like we have to wait for all the files to be released......
Any day now Moto, util then people will continue to send these devices in and con the stores . For this, I applaud them.
This might work or it might not.
I had a bricked xoom too. no matter what fastboot i entered it wouldnt recognise it. all it would say is "waiting for device"
This is what i did.
Turn the xoom off
Do not connect you USB cable yet
Fastboot reboot-bootloader
It should say "waiting for devices"
Now plug your xoom
Turn on the xoom.
When you see the Motorola logo press volume down till you see "fastboot protocol"
Press volume up.
It recognise my xoom that way
couldnt turn mine off. let the battery run down. plugged it into power booted it up. no help. bricked

I have to admit, I'm one of them. Sure is a nice way to tell Moto to hurry the F up. I can't say I felt great about it but I wasn't about to lose $600 either.
me to one of them
shipped mine back to the factory today. not sure what they can do to it. is there such a thing as a force flash or will they have to replace the firmare chip to make it work? unstable combo tegra and honeycomb, aint messin with mine anymore.
i just recovered mine from this. i flashed recovery with clockwork mod:
at the rsd 3 screen with the usb attached
fastboot flash recovery recovery.img
held the volume down while pressing the power off on until fastboot started flashing the recovery
fastboot reboot
xoom started in clockwork mod, did a restart and it worked
****This happened after attempting to load recovery from rom manager without flashing new recovery image.***
Did you happen to mention in your explanation about what went wrong with your xoom anything about unlocking or relocking?
Hi All:
First-time poster here. I searched the forums but could not find an answer to my problem.
I want to root my A700 and install a custom ROM but I can't get the bootloader unlocked. I have followed the instructions from this post but can't get past the first step. ADB definitely recognizes my device [adb devices] by returning the correct s/n. When I enter [adb reboot-bootloader] my tab reboots but then hangs on the green Acer logo and goes no further. Any attempts to use ADB result in a "waiting for device" message. My only option is to power off by holding the power button then reboot normally.
Here's my device/PC info:
A700:
Android version: 4.1.1
Kernel version: 3.1.10+
Image version: Acer_AV051_A700_RV18RC01_PA_CUS1
Build Number: Acer_AV051_A700_1.052.00_PA_CUS1
PC:
Windows 8 Pro 64bit
Android SDK 64 bit (I also tried 32bit with no luck)
I have rooted devices before so I am not totally new to the process, but no expert either! Any thoughts?
Thanks in advance for any advice/info shared!
Note: Had to use Acer USB driver for ICS. There was no USB driver for JB. Could that be the problem?
Perhaps try to reboot into bootloader manualy. For this first switch off your device, then press power button and volume (-) together. As soon as the tab vibrates, release the power button and switch the screen lock two or three times. Then you should get into the bootloader mode and can try to use the adb commands. Of corse, with a connected usb cable.

Good thought but no luck.
Thanks, though.
After rebooting with "adb reboot bootloader" you should be in the bootloader, and in fastboot mode. Try issuing "fastboot devices" after rebooting.
Edit: Just tried the unlock guide from that thread, and with the ICS driver from Acer. Getting the driver to install was way worse than unlocking the bootloader (many "installations" that didn't create any files for whatever reason).
After ADB recognized my tab, I was able to follow the guide up to the "flash recovery" part.
- with "adb reboot-bootloader" you should land in the bootloader. It only shows the Acer logo and some very small written things in the upper-right corner;
- from here on you need to use fastboot: "fastboot oem unlock". Typing "fastboot devices", as I said before, works just like "adb devices";
- the whole unlocking procedure is very frustrating, because the instructions are so small and the timeout so fast. If I'm not mistaken, you need to choose with VOL- and confirm with VOL+.
PS: pmrmx was faster

After the ADB reboot-bootloader, there should be some really tiny white type in the upper left corner of the green logo screen.
This is when you type "fastboot OEM unlock" then volume +, then volume -
The tiny type should change. Forever after you will have a tiny message up there about the bootloader is unlocked.

Unfortunately, the problem is that the little white text never appears - that's where it hangs - the screen is completly blank except for the green Acer logo. And if I try to enter "fastboot devices" I simply get another adb prompt (nothing else - it just jumps to a new line.) If I enter "fastboot oem unlock", adb returns "<waiting for device>" and then goes nowhere. All the while, for both commands, the tab is stuck on the Acer logo.

You probably need to install adb USB drivers ( android universal USB driver I think which is different than the Acer USB driver ). While adb will work when tablet is in USB debugging mode, once it rebooted your PC can't communicate with it anymore that's why its waiting for the device.

Thanks, hey_joe. I actually already tried that but decided to try again. This time it worked! I don't know what I did differently but bootloader is now unlocked!
Thanks, All!!!
Tablet ubislate 9ci hanging on bootloading
Dear sir/madam, I am new to this forum. I purchased a new tablet Datawind Ubislate 9ci. It is a 9 inch no-bluetooth tablet.
>Details:
>*.Android 4.1.1
>*.Rock chip RK2928
>*.KERNEL linux version 3.0.36 i was trying to install CWM through mobile odin and ROM manager but my tablet was not supported so i downloaded build.prop editor from google play and changed it to some other cwm recognizable model viz. Samsung, nexus etc. When i was doing the above mentioned procedure, suddenly my tablet is coming up to bootloading and hanging there only and not opening i tried to go to recovery by pressing power and vol but i am not getting recovery menu, i also tried to hard reset by pressing reset with a needle at the back but all in vain again hanging on bootloading i also tried press and hold power & vol- and several other combinations , all in vain so kindly help me and guide me Thank you
Hello there. First of all thank you for your support. I'm here because I have the same problem as OP, but first a little context.
I have already rooted my A700 before, without any difficulties. But after a crash, I restored it to factory and tried to redo the whole procedure.
So, here I am, USB driver installed (I had to modify android_winusb manually for windows to finally accept the drivers), adb up and running, adb reboot-bootloader executed and...
Acer screen, no text, just like the OP. And a yellow "Fastboot" device in my Device Manager window. So I'm stuck here. I've tried to uninstall/reinstall the google USB drivers to no avail, unlike OP. I can access the Acer recovery with the reboot recovery prompt, but I'm not confident enough to ignore the step in this tutorial.
Additional precisions : when the device is stuck with the Acer Logo (without text) trying to use a fastboot prompt (like oem unlock) only gives me the <Waiting for device> message.
I could use the Acer recovery to install a rom from external storage, but I'm unsure if it's a good idea to NOT use CWM or TWRP
Thank you, I'm starting to miss Android 4.4 (yeah, because the Acer update manager give an error 400)
Update : I did manage to access fastboot. Just as I had to modify android_winusb with the PID of my tablet when it was running, I also had to edit the file with the PID of the tablet waiting in fastboot. I didn't noticed they were different.
Hey guys,
I've seen some solutions for my kind of problem but none of them seems to start at my frustrating point.
After I rooted my HTC One S I was able to reboot my device and everything went fine.
The problem occured just when my battery was depleted and the phone got turned off I had no chance to restart it.
The LED did not show me it was charging and it did nothing, when I pressed the power button or the volume/power combination.
So i connected it to my laptop and tried to check my devices through adb.
It says my device is in recovery mode.
Using the fastboot reboot command I was always able to reboot my phone and everything was just fine.
I thought it was alright, as I just had to pay attention not to use up my battery, when not at home.
Today my phone just decided to turn off. It refuses to boot up even with the fastboot help from my PC.
It just says: < waiting for device >
certainly I'm unable to post a link to a screenshot I made of my cmd.
Thank you for all kind of help
I have tried just about everything I can find to fix my Nexus 7. When powered on it shows the Google logo and hangs there. I have checked the battery connection, checked the other connections that are visible when the cover is taken off and everything is ok. I can boot to the fastboot mode. I plug it in my computer and it loads the drivers. I can a cmd line command "fastboot Devices" and it shows that my device is visible. Then I can enter the command "fastboot oem unlock. the tablet asks for the yes or no question i use the volume up to say yes and the cmd line shows unlocking and erasing but the tablet freezes and nothing happens (for hours). I then hold the power button and shut off the tablet. the command line then says failed because of to many links.
The laptop has not been rooted, this is a bone stock Asus nexus 7 2013.
I am attaching a photo of the fastboot mode screen.
My question is...I am beating a dead horse is my nexus 7 bricked permanently.
I think the problem is not being able to enable USB debugging. Is there a way to enable USB debugging when so can't get into systems in the tablet?
Thanks for the help. if you have any questions please let me know
