So I went to turn on my Transformer Prime today, hit the power button, it vibrated... And that's all she wrote. Nothing after that, nothing since. I go to plug it into the computer and the tablet doesn't do anything, but the computer says "Unable to Connect to Unrecognized Device". Any ideas?

I just got same thing over this weekend. My wife took it out side and discharged battery.
After charging, I hold down power button and it vibrates but shows nothing on the screen. When I connected the device to my computer, Windows Explorer showed Transformer device. So I got suspicious and connected the device through HDMI to monitor and there it is! The device kindda works! It responded to my touch and all but not a darn thing on the screen!
Since I unlocked boot-loader, my warranty with ASUS is voided. At this time, I don't know what to do. Any idea?
faulty TF201

Here also, i seem to have this simulair problem your writing about.
When i connect the USB to pc, is doesn't recoqnise my tablet.
When i connect the HDMI cable to TV, there is no video signal.
When i press volume up + power button, nothing on screen. It does give a short vibration. Flashes 3 times.
When i press volume down + powerbutton, nothing on screen. It does give a short vibration. Flashes 3 times.
When i charge it for 8 - 12 hours battery would not charge.
When i discharge the battery is doesn't do anything.
When i connect tablet with asus charger it only shows a yellow light at power button.
The warranty on my unit has expired. Therefor i have been trying to find a solution myself.
I could not find a replacement mainboard, so i have ordered a new LCD display.
Because maybe my display was faulty and system was stuck in splash screen?! what i could not see.
Unfortunately the replacement LCD display didn't show any differences. I think the mainboard or battery is broken.
Maybe someone have some more good ideas?

Hello,
I was wandering if my tablet is hosed or not because of the following information after I tried to install early preview
of ICS and I have opened it. I have taken to a repair shop but they would touch because 'they think it is a software issue.' Software would not cause the followine:
A:My Tablet will not turn on.
B:My Tablet is not seen by my pc(I have tried every plug)
C:Master reset button does not do anything
D:When I try to run APX, it says that there are no usb connected.
E:When I either try to charge with/without dock, it will charge for about 30mins max then the charge light will shut off.
F:Windows does not recognize my tablet when connected to my PC.

Perhaps you have been here but this site helped me out many times.
http://viewsonic-gtablet-for-dummies.webs.com/
See this post.
I would use this thread if my tablet could actually turn on. I have tried to see if it will show up in APX mode.
Have you checked to see if you are actually just in APX mode?
There won't be a thing on the tablet screen, will look like it's off (no color change of the black "off" getting lighter from being "on", etc..).
If you were able to nvflash before, have you tried nvflashing again?
Just as a test, plug the tablet up to your PC (that you have used nvflash on before....so we know your USB config is valid for the Gtablet), go ahead and hold the volume - down and then press power for just a second. Now try to nvflash the device.
My tablet was stuck in an APX boot only process for a LONG time (about 9 months). I could nvflash it with different ROMS to test, just couldn't power it off because once I did....it appeared to never come on again. Reset button did nothing, Power button did nothing, screen was just "off" black period. I could still nvflash....

You should go through those links a bit more carefully. Watch that youtube video for a start.
I got home after school and tried all suggestions and I still could not get it into apx mode. I watched the youtube video but I could not get my computer to recognize it like it does in the video.
If you've checked your USB cable
and done the HW reset procedures in the posts correctly
and also tried the nvflash on Linux
and if the tablet still doesn't go into APX mode,
then you might have truly bricked your gtab.
They say it is unbrickable--but, really, it is not.
You got an SOD. Fosser warned people that tried the ICS alpha about this. The only thing you can do is unscrew the back and press the reset button on the mainboard. If that don't work... sorry you killed your Gtab.
Thanks for the help
Well,
It does look like I really did brick my tablet because I have TRIED everything. I knew what I was getting myself into when I flashed it.

You could try installing Ubuntu on a spare computer, and see if Ubuntu detects your gtab. Ubuntu does not need apx drivers. All you have to do is plug in USB open a terminal and type lsusb and hit enter. You will need to attempt to put your tablet into apx mode with power and volume down first. Doing it through Ubuntu will eliminate the possibility of a driver error.

I already had similar situation. Used power consuming USB HDD to train my battery.
After 24h - my G-tab is back
Ok so I was at work listening to music when my phone froze. Pulled the battery, which was only at about 85%, and tried to restart. And, nothing. No green light, no dual core screen. Tried four different chargers, including OEM Motorola charger, and tried hooking up to my home PC. Only thing that happens is when I hook up to the PC without the battery in the green light comes on. Power button still doesn't turn the phone on. Just turns off the light. I tried to search, but the closest I found was people stuck at the dual core screen or people who didn't realise their batteries were dead. If it helps, I'm unlocked, rooted, and running GingerMod 2.3.6. Any help is appreciated! Thanks!
Sam issue
I am having the same issue with my wife's phone. We both have Atrixes and I have tried swapping batteries and her battery works fine in my phone. I still can't get it to start up. No green light when plugged into the charger but a solid green when plugged into usb on my PC. How did you end up solving your issue?
I got this problem once. To fix, pull battery out, plug in wall charger to phone (without battery), should boot to the battery with question mark icon, plug battery back in.
I work at a cell phone repair store , and from reading your symptoms I think you might have an issue with the flex cable running your LCD. In the atrix if you drop it there is a possibility of shaking the flex cable off your board, and its a matter of micro soldering or just connecting the cable. I DO NOT suggest doing it yourself. If you want it done professionally call my work. 6053350411

I solved this problem with wall charger
Will anyone here elaborate how to fix it again?
If I plug it in wall charger, no response and no light.
If I plug it in USB, green lights on without battery, no light with battery.
In any case, pressing the power button cannot power on the device.
Please help. Thanks.
Sounds to me like your battery is having issues. Maybe try getting a new battery?
Thanks for your quick reply. I have actually got a new battery already. Still the same behaviour.
Then I can only assume it's the phone. Perhaps the charging circuit. In any case, sorry but I have nothing to recommend. :dunno:
If the plugging it into the wall without a battery in it didnt work... then try waiting for the phone to boot (assuming that it still is and the LCD is disconnected) and swipe where the unlock button normally is, pressing volume up or down, or perhaps try ghosting to adb and run adb devices in the command line... or simply try calling it lol. Also a good piece of information to get... does the backlight come on? If you can prove that the phone is in fact running, then it is most likely the lcd cable as someone said...

Thanks for your advice. I didn't drop the phone before it went to "no-response" status. I just put it on a HD dock for charging and the next day it doesn't boot anymore. I have put in HD dock for charging for a few weeks already.
My phone doesn't boot at all. I don't see any backlight or any special response. Or It does something that I don't know. I tried to plug into USB after pressed the button. If it's on, the computer should detect a device, right?
Any ideas are welcomed, i will try all.

I have the exact same problem, and would be grateful to know if you managed to resolve this problem.
I hope this is the right sub-forum to open this thread if not please movie it.
Half an hour ago I Got the 9.4.2.15 firmware update from asus. after the update was applied my prime asked me if I want to turn it off....I approved and the device shut down and stayed off.I tried to turn it on and nothing happened.
When I applied the update I had more then 80% of the battery.
I plugged the phone to the charger and the charger light on the power button changed from orange to green
While the Prime was charging(and after it was fully charged) I tried to do some stuf
I tried to press the on button and nothing happened and no vibration.
I tried to hold the on button for about 30 seconds and the only thing that happened is that I got a vibration(the same you get when you turn on your device).
I tried to reset the device with the reset hole near the microsd with a needle and nothing happened.
I tried holding the power button and the volume button(once the up and the other time the down) and nothing happened except the vibration after about 10 seconds.
ANY IDEAS?
*my biggest problem is I purchased the Prime from "Amazon US" and I don't leave in the us...How If I need do I use my ASUS warranty.who do I connect?
Thanks.
Try draining the battery completely then charging it back up. Then try to boot it up again. You might have a glitch or bug. Its always good after an update is applied to let it update then it reboots itself. After it loads back up,go into home screen. Then **** down device and cut back on. This will eliminate anything happening from rogue codes.

Good luck

*By the way I have the option to take the prime to a shop that could fix it, I am sure the problem is a software bug and not hardware...Should I try doing this because ship it to asus ans back will take about 3-4 weeks.
Try a hard reset and if that doesnt work do a search for this (EP201_SDUPDATE.ZIP)

I am unable to do "Hard reset" because the device do doesn't start, after pressing the power button nothing happens the screen stays black. the onle response I get from the device is vibration(after I hold the power button for about 10-12 seconds).
I don't think that "EP201_SDUPDATE.ZI" will help because I don't have accesses to my bootloader
Did you happen to drop the device or bang it pretty hard? If so, could be a chance the connector to your display is loose and device is actually on but the screen is off. Best way to check this is to connect your prime to your t.v. thru HDMI. Then try to cut it on. If something displays on your t.v. but screen still won't cut on, then connector came loose from your display. That is the best way to check. Plus you could also operate tablet like that.
Nope,didn't drop or hit it.
Unfortunately I don't have HDMI cable that connects to the prime.
your idea is good but even without the cable I am sure it's not the problem...but lets say that it is the problem...then if the device is actually on I should be able the hear the sound it makes when I use the volume buttons and when I receive new emails...the thing is I am unable to produce any sound from the device.
I just applied my update and it didn't ask me if I wanted to power down, it did itself. Did you power down when it was starting to install?
My screen did say "power down" but I knew it would do it itself.
Maybe like doing a battery pull during a flash?

Maybe you are right and for some reason I turned the device off while it was in the middle of the update... so 5hat means as you said that I interupted the flash process...in this case the problem is the software of the device ...could I do somthing to fix it without going with it to a lab?

You might try inserting a pin or a paperclip into the reset hole next to the micro SD port.
PROBLEM SOLVED!!!
I decided to try and fix my prime one last time before I use the warranty. so I took a needle SMALLER one then I used the first time I tried to "Hard reset" the prime and inserted it into the hole near the microSD port....and this time I felt a "click"...I pressed for about 10 seconds and then released and the screen turned on
I immediately got the screen withe the open green robot and with a blue line under it that showed me that the update was applied....then the screen changed to the screen you get when you turn on the device(asus symbol and tegra3 symbol) and again I got a blue line showing me that the update is going on.
After the blue line went foreword to 100% it disappeared from the screen and I was left with the screen you get when you turn on the device(asus symbol and tegra3 symbol).
I have waited for about 20 minutes and nothing happened....I turned off the device with the power button and then turned it on again(this time the device responded after 1-2 seconds)...I got a vibration and the screen was on(asus symbol and tegra3 symbol). after a few seconds the screen changed to another screen( another ASUS symbol with a turning circle under it) after about 8 seconds my device was fully working all my data was present(didn't reset with the needle should have deleted everything?) and my software number was 9.4.2.15,so the update was fully applied.
I tried turning on and off the device for a few times and had no problems with it.
So basically the device is working and I have no idea what was the problem
The tip i got for everyone trying to reset the device with a needle/paper clip....YOU HAVE TO FEEL THE CLICK
that's awesome! Congrats!
These are expensive toys (in my case addiction).
Maybe it was a bad flash which can be really spooky if you're not rooted with a custom recovery.

Hi I'm really hoping someone can help me. I received a Sony z2 tablet spg521. I was told it was new but it would not power on or charge, and the charge light would sometimes blink red. Well I got the fixed or so I thought by doing a soft reset and then pc companion...sounded simple but spent a couple days trying to be successful. Sometimes my computer would recognize it sometimes it wouldn't.... Any way I finally got it out the blue dont know what the difference was I was just happy it finally worked... I then fully charged...yadayada and used it flawlessly for about a week... It would turn on and off, battery held charge like its supposed to, everything seemed to work.....then I went to power off but hit the restart by mistake....no there is no power again and this time it will not do a soft reboot.....no light ever....computer will not recognize ever....I have been trying off and on for a few days.....among-est my research to try to correct it seems like this is very common....when i shut it off the battery was over 50%..so how can something work fine then just die like this??? Ive seen that sometimes with sony if you disconnect the battery and the reconnect this will work... does anyone know? does anyone have any advice before I take apart this cherry tablet to try the battery thing???
I would really appreciate any insight as I have fixed many of my own problems and for others from advice on this site. Have a wonderful day and thank you!!! :silly:
ok today i tried to use flash-tool that Ive read about on this site....when it asked to plug n device computer recognized it and red light came on, but flash-tool did not recognize it....torn between letting it set and seeing what happens or trying to get the flash-tool to work, I chose the flash-tool...bad mistake when I went to try to reconnect and see if the FT would see it..it was no longer recognized by the computer and no light but computer did say USB device not recognized and not installed correctly.....now I already have the right drives so now Im really confused..tried a couple more times with same results and then once again nothing...no light no soft reset no recognized at all by computer not even not recognize USB....so disappointing loved the tab but this is insane that sony does this as its not user error but sony error and they dont even man-up and try to make it like you dumb or something....will try again..when i calm...
reset the device by pressing power+volume(up or down) for several seconds. It seems like a toasted one, possibly caused by putting magnetic charger on wrong polarity.
Thank you yes Ive tried all kinds of resets I have found...I agree seems fried but I would not know how. I have not used a magnetic charger...only the regular sony one that came with it....
So last few days I have tried off and on again....now computer recognizes by making noise when connected and disconnected but does not show up...PCC does not recognize it.....flashtool says its connected in log but when it asks for it to be plugged in it never leaves the screen telling you how to connect....when I try to connect the charge light comes on for about 4-5 secs then turns off....still no vibrate when try to reset still no light when plugged to a charger.....I want to get another one but I am scared this will happen again....gonna chuck this one as if time is money then I have well exceed the worth in time... I only got this because some time ago a sony z1 came my way and I so love it...i recently upgraded to z3.....i have a lg pad but screen got broke so I got the sony tab....maybe Ill just fix the lg

Mine is kinda toasted and this is how it works. Whenever I have a problem, I have to reset by pressing power + volume up, as soon as I hear three vibrations, I turn it on by pressing power button. Otherwise this tablet will just repeat sony logo and no boot. If you have bought one "NEW" make sure to return or replace it. If you want to enter fastboot mode, repeat the resetting routine and pressing power button to turn on, but also right after that or even simultaneously press volume up to enter fastboot mode with usb cable inserted, or volume down to enter flash mode. either way, your unit is toasted and sony sucks.
Well, I have the same problem, and isn't fun. Just very extreme rare cases it turns on the screen charging the battery, but doesn't turn on sadly
I did a happy boot today after 3-4 months off with several times trying turn it on, and did all the tricks from all treats about SOD
Last weekend I did a full charge from deep red to green light and battery animation on screen at start, but no luck.
I put it back in the box
This weekend I got some visitors, one of them asked about the tab, told him it didn't work and showed to him
Pressed the power button and to my WERY BIG surprise, it vibrate and turned on as nothing was wrong
The battery was only 54% after one week off. it received a update (264) and I installed as normal, turned off and on again as normal and happy I was

My tf201 seems to have gone into a bricked state. It crashed while my son was playing a game on it. Instead of restarting it never came back up. Thinking that the battery may have run out I plugged it into the AC charger overnight. While connected I could see an orange LED by the power button glow.
Now I can't get it to start. When I hold doen the power button, it vibrates for a several seconds but the screen remains completely blank.
Unfortunately I no longer have a USB cable for it. Is it worth buying one on the off chance it can be recovered?
