[Q] Completely unresponsive Xoom

I've got a 4G Xoom, that I bought new about 13 months ago. It's been great to me so far. I had it rooted and was running CM 9 on it and had been doing so for about a month without any issues.
Yesterday, it was plugged into the charger and I happen to glance at it and it was doing some strange things with the screen, flashing on/off, black lines on part of the screen. I powered it off and left it alone for an hour or so.
Since then, it's been completely unresponsive. I've tried Vol Up+Power button countless times without it working. The charge light (white) came on briefly while plugged in, but then went off, never to return. The only reaction I can get is that after holding Vol up+Power causes an orange light next to the front camera to blink twice. That's it.
Any suggestions? Is it completly dead?

Given that it's sealed, how is this done? I hadn't even considered cracking the case.

You may not need to remove the battery as several people have reported success with just slipping some paper between the contacts for 30+ seconds. You will need to open it up though and here's a post with info and pictures to guide you through that: http://forum.xda-developers.com/showthread.php?t=1578365
On edit: here's another thread with good info for you http://forum.xda-developers.com/showthread.php?t=1528706&page=3
Good luck.

Well, I did the paper under the battery terminals for 15 minutes and still no joy.
One item of note is that when I plug the charger in, I'm not getting a white (or green) light. At least not much of the time. Occasionally, I can wiggle the plug a bit and it will light up, but I'm not getting to green at all.
I can put a multimeter on the battery leads, does anyone know how many volts/amps I should be reading?

Are we sure that its not just a crap connection with the charging plug. It is a wimpy little pin and my Xoom needs me to do a rain dance to get it to charge. I have to plug it in, wait a few seconds and then the white light comes on , but only if the wire is flipped back over the top of the screen. Another thought is I use Tiamat ics and there is an option to have the light on or off during charge and I think it is set to off as default, maybe you didn't set that up. I would bet its something stupid and you just need to keep playing with the wire and see if you can get it on. Good luck.

[Q] Properly Bricked Xoom - no screen whatsoever

hi everyone, I have a challenge for you...
My MZ604 Wifi Xoom is completely unresponsive. No boot logo, no screen nothing.
A few months ago I flashed a US stock to get a hold of the ISC update. it went off without a hitch and I was very happy with it.
A few weeks ago I picked it up and it was black and not booting, even to the logo. Nothing.
The only things that light up are the white charging light when it is plugged in.
When I plug in the USB (Win7x64) it registers as a Motorola Flash Interface and charges through my computer- but not all the time.
I have tried many combinations of button pressing and holding, and the only indications I get that it is working underneath the black screen are the white front light going on and off and the device registering in device manager.
Oh, and it makes the battery low sound when low on battery, which i hope is a good sign.
Adb fastboot does not recognise the device no matter that I do.
Has anyone ever come back from this???
Desperate,

This might be a case for the Motorola Programming cable from the Black Hat Team (google it). You can also make one. There are instructions somewhere in one of these threads.
Have you tried to take the cover off and remove the batter(ies)? Look for the thread with instructions for that. You will need a Torx screwdriver (#5?).
I'll bet you can bring it back.

thanks okantomi,
I just ordered a torx set, hopefully a battery disconnect will work.
Very hard to figure this out, every single search i made for 'bricked xoom' came up with silly buggers with frozen boot screens. Not a real brick at all...
If you don't hear from me again, assume it's fixed!
Thank again

Good luck!

We havent hear from you since so hopefully you fixed your xoom!
Can you share your experience for whoever has simmilar issue....
Thanks
&
Good Luck

Xoom US Wifi: Appears dead

Hi,
I'm having an issue with my Xoom Wifi (US, original). It's running Jelly Bean and is unrooted, locked, and stock everything. It won't turn on.
Today, I was charging the Xoom, it was on and at 15% battery life. Later, when it around 45-50%, I unplugged it and let it be on standby. Later, I returned to it and it was unresponsive with a blank screen. I don't know if it was on at that point. However, at one point I noticed that the screen was backlit (but still showing black), and holding down the power and one or both of the volume keys for a few seconds turned the Xoom off. Since that point, I have been unable to turn it on.
Status of Xoom:
- Charging appears to work. White LED showed when charging, then later changed to green.
I've tried the following:
- Waiting for Xoom to charge (LED to turn green), and holding down the power button for a few seconds; holding down the power button for a minute, holding down the power and volume up for a few seconds as well as up to a minute, holding down power, and volume down for up to a minute, as well as all three buttons. I've tried these steps while plugged into AC as well as not plugged in.
- I've also removed the battery for at least a few minutes before reinstalling it and tried the above steps for trying to turn it on.
ETA: - Also tried removing microSD card.
It still doesn't seem to be turning on.
What are my options?
Thanks.

Can you access the device via fastboot or adb?

I'm not sure if my fastboot is set up correctly. I'm having difficulty using it on my Mac running Mountain Lion (getting (ERROR: could not get pipe properties), when I'm doing the ./fastboot devices command)
However, when I run "./adb devices", I can see my Galaxy Nexus as an attached device when it's connected, but not my Xoom. I've tried holding down all combinations of power+Volume before running the command.
ETA:
Okay, got fastboot working by rebooting my phone into bootloader mode. I can get my Galaxy Nexus to show up when doing ./fastboot devices, but I can't get my Xoom to show up. Note that the only output from my Xoom right now appears to be the charging LED light that is usually white, but turns green after a few minutes being plugged in.

Am no expert but if your charging it with a white light then a few minutes later it goes green the problem might be your battery has died completely (just a thought)

I don't think this is the case. Green indicates that the battery is fully charged. When it died, the battery was about 50% full. It took a few hours for the battery to charge that the light to turn green. Now when I plug it in, it is initially white and then turns Green after a few minutes, indicating that the computer thinks that the battery is full.
Does anyone have ideas? Would getting/creating the special diagnostic motorola USB cable be of any help? How can I diagnose what's wrong? I don't mind disassembling the device if it would help.
I usually have limited access to parts, but I will be visiting the US in a few days so if you have ideas for useful parts that I can order that might help let me know.
Thanks.

Do you got any response when you connect the XOOM to your MAC with standard USB cable?
Can you try it on Windows PC?
If nothing response, try to connect with "factory cable".
P.S. I bricked my XOOM, it's only recognized as APX device. After I installed drivers, It could be recognized as "NVIDIA USB Boot-recovery driver for Mobile devices". And then nvflash command could be executed and got some response. I hope I could got progress, but I still stuck here. All indicated that I need original "bootloader.bin", and BCT and config files. I also try to send it to different MOTO local service centers, they told me that maybe I damaged the hardware(?), if I want to repair it, the motherboard must be replaced. Anyway, hopes this information could finds you. And if you solved your problem, please just let me know how. Thanks in advance.

Well, my Xoom did the same thing as described in the OP last night. Power button was unresponsive but could charge. Googled around and found that many people fixed this issue by pressing volume up + power for a few seconds. Tried it and worked. Xoom booted up, and I gave a sigh of relief.

I feel you pain
I'm having the exact same problem that Lyrrad0 initially reported.I couldn't describe it any differently. It's great to see someone else is experiencing the same thing. A lot of posts that i see mention doing the power button + Volume up button fix, but this doesn't work for me and sounds like it doesn't work for Lyrrad0 either.
Like Lyrrad0 i also think the battery is fully charged. I saw a few chipsets that i could buy but it would be annoying if it didn't fix the problem still and i had wasted my cash.
Just wondering if Lyrrad0 tried to replace any parts? If so did they fix your problems?

TF101 Won't turn on - Question

I am hoping someone can help...
I have a TF101 tablet that my kids use and we use to play movies on when we travel.
Yesterday my kid was playing a game on it. When it was dinner time she exited the game and pushed the power button to turn off the screen. Now it will not turn on.
It is not dead (the battery was just charged prior to her playing the game). I tried holding down the power button for 15 seconds. I tried Power + Vol down button, Power + Vol up, but nothing! Just a black screen.
Last year the exact same thing happened to the tablet. I was using it, turned off the screen and then nothing! Just a Black Screen and nothing I did worked. It was still under warranty so I sent it to ASUS. They received it, fixed it and shipped it back out to me 3 days later. When I got it back it I noticed that nothing was wiped from my tablet. All my apps, all my data, everything was still there. So, I figured it was THAT big of a problem that they had to do a Hard Reset or replace my tablet.
That said, since it happened again, I am hoping someone might have a fix for this. It is not under warranty anymore and we are going on a trip in 1 month and I would love to get it working so the kids can watch movies on it.

Won't it turn on when you connect the charger to it either ?
Faulty power button ?

Yea, nothing.... I plug in the power cable and still just a black screen. (I have 2 cables and tried them both)

I know they are prone to pulling the LCD cable out of the board inside if they are dropped or knocked, the cable is wrapped around the battery which shifts when its knocked and pulls it out
If you're happy to open it up, its an easy enough fix to push it back in
Sounds likely that's what's happened
This is a good teardown video, the cable is the silver one iirc
https://www.youtube.com/watch?v=k-6dKsGJ4VY

Thanks, I will give it a try.

Well, I took it apart and the cable seems to be ok. I even removed the cable and reinserted it. Still nothing.
I did not check the other end of the cable (the one that goes under the board) as it would require me to remove a lot more stuff to get to it.
I am pretty sure it is the screen though because if I hold the power button down, after 10 secs or so I can hear a *click* sound. So I am assuming it is still working, just something is messed up with the screen.
I might break it down even more and check out the other end of the cable when I have some more time.

I hope it's not you power button, because request changing part of motherboard (79$)

Plugging in the charger would turn the screen on
---- @op - Does the screen backlight come on ?
If not, if you tilt the TF and look carefully at the screen, can you see an image ?

So apparently I was messing with the wrong cable... I found another video that shows what cable to check. I will be checking it later today, wish me luck... I was checking the silver cable running from under the battery.
Here is the video

Yea that's the cable I thought it was too, my mistake!
I've not had this exact problem so assumed as it was wrapped around the battery that was the cable in question
Good luck!

Well, that was it! Once I opened it up again and looked at the right cable I could see it was pulled 1/2 way out. Plugged it back in and it worked!
Thanks for the help!

fix to turn on transformer 101 tablet
I had this problem with my asus and windows tablets. Unplug everything from it including base micro sd card and any usb plugs get an alcohol wipe clean all the charger plugs and sockets don't soak just wipe. When done plug charger to mains power and tablet it should turn on. If the on board battery is flat may take a couple of goes to start. Worked a treat for me.

What to do if I can't see any image or any light?

Hi,
I guess I am having the same problem. So, what should I do if I can't see any image or any light on the screen?
And btw when I press the power button, immediately within 1 second I can hear a click sound.
Thanks in advance.

Galaxy Tab GT-P3113 doesn't turn on nor recognized by pc.

Hello Guys, it's been awhile since i needed your help for the last time. Right now i'm having issues with a Galaxy Tab GT-P3113 i recently got from an aunt. The tablet is not working but i want to see if there's any chance to bring it back to life before i dipose it to the trash. Any of your kind comments will be very appreciated.
Here are the facts i noticed since i got it (5 hours ago):
.- Tablet does not turn on normally, by pressing power button.
.- Tablet does not charge from the wall input.
.- Tablet is not recognized by 2 laptops at this moment
... but here's a little twist: even when my laptops says it doesn't recognize usb device, the tablet shows the charging icon for about 3 seconds, then it fails and "reboot" again and again... So, by experience i can say that there's something possible to do with it...
If you have any ideas where to begin, it would be very awesome.
Thank you in advance for your support.
PD: i have already tried pushing buttons for 25 secs to one minute, with or without holding vol down and up.

Maybe you have not thrown away the tablet yet.
Two solutions:
1. Connect the tablet for one hour to the charger, then the battery may start charging.
or
2. Press the power button for 30 seconds, connect the charger without releasing the button and after connecting it, hold it for 30 seconds.

Once i had this issue too...
The fault in your usb cable. Get a new one from Amazon or somewhere else and give it a try. Most probably your issue would be fixed.
