Bricked Touchpad need help

NOTE - I added this post here thinking the CM9 experts could help. I then realized it should be in the Q&A section. If this does not belong here, I ask a moderator to please delete it.
I have been running CM9 nighties for some time now with no issues on my 16GB US WiFi only Touchpad. I installed TWRP and after some time decided to remove it and just use CWM. After trying several things from the posts (which would not work) I decided to remove CM9 completely then reinstall. This is where I got into trouble...
I loaded all necessary CM9 files in the cminstall folder on the Touchpad. I successfully ran ACMEUninstaller and got back to the WebOS language selection (i.e. the initial WebOS screen from factory). Instead of logging into WebOs (felt there was no-need since I never use it), I put the unit in Download mode (vol down + power). I then ran ACMEInstaller2. I received an error (text on the black touchpad screen which I assume is the bootloader) saying the needed files were not installed and something like "remove the wall". I thought I would reboot the unit and now log into WebOS and reinstall the CM9 files (thinking I made a typo when loading them). Now I cannot get the Touchpad to reboot - totally black and even when connected to the PC I dont get the USB connection sound.
Does anyone know if there is a hardware method to bring the unit back (maybe a different sequence of button presses or shorting a pin on the USB connector)? I have tried home+vol up+power, home+vol down + power, home + power, and of course power only and home only. Each combination was held for 30 seconds and then again for a minute and with power connected, PC connected, and nothing connected to the USB port.
Any thoughts would be greatly appreciated.
Resolution: In a post I saw dated May of 2012, the user indicated HP was still honoring their warranty. I contacted HP via their Chat service, after giving them my model and serial number, I was told I had three weeks remaining on my warranty. HP sent me the return box with authorization and in a week I received (what seems to be) my exact Touchpad... only now it booted just fine. I have since reinstalled ICS and am running fine. Thanks to all who responded. I wanted to share this as I am extremely impressed with HP's warranty service (no questions were asked if I had rooted the device, where I bought the device, etc).

I remember this happened on my brothers and what it was is that the battery was completely dead. I believe it has a backup that needs to charge before the main one. That's the only time I have personally seen this happen. Perhaps if you leave it on the charger for a while it will boot and u can use web os doctor to get it to stock.

Thanks, I let it charge all night then tried it this morning (as described not just powering it on). Of course, with only a black screen I can't tell what the charge is. I have checked the cable and am now using a different power supply in case that had failed. I think because this happened during the removal/install process I scrogged something in the bootloader?

It's a good idea to use only stock cable and charger.

No, totally black device. I was hoping at least I'd get the USB connection on my PC, but not even that.

This happened once to my TP when I first put CM7 on the device a while back. I woke up one morning, forgot to plug it in overnight and it had died. No response to any charger, I was getting worried but then I found a solution. With it plugged in, hold the power button and home button down together for 15 to 30 seconds. It was that or hold the power button down and keep pressing the home key over and over. Not 100% sure, but it came back to life and I remember it took me a couple tries. Try holding both down simultaneously for 30 seconds or a minute, if that doesn't work, push and hold power first then home right after and hold both for 30 seconds.

Okay.... hard reset has been a life saver for me. Hold the home button down, then press and hold the power button, so you will be pressing them at the same time. Keep holding them till you see the HP splash screen, it may take a few min and seem like nothing is happening. I thought I fried mine the first day I got it, but this worked for me!
Good luck!
And, if you decide that does not work for you there is such a thing as the WebOS doctor which will get you back to stock. Link here: http://en.m.webos-internals.org/wiki/How_To_Recover?wasRedirected=true

This post should do the trick for you....just press the power and home buttons at the same time, hold them down for about 30 seconds until you see the HP logo on the screen then release them...good luck!!!:good:

Nope... As stated in the OP, "I have tried home+vol up+power, home+vol down + power, home + power, and of course power only and home only. Each combination was held for 30 seconds and then again for a minute and with power connected, PC connected, and nothing connected to the USB port."
I need to know if ACME Installer is doing anything in the Bootloader. I have flashed and reflashed CM7, CM9, and multiple ROMs. Even uninstalled CM all together when I went from CM7 to CM9. I am familiar with getting into Download Mode and the hard reset (which apparently isn't solving this issue).
I appreciate the feedback, just hoping someone familiar with the Bootloader and Touchpad partitions can help out.

If the battery was low when you got into this state then it could be that there is not enough power to even let the charging circuits work properly. WebOS has better protection against getting into this fix.
I experienced this once and the trick that fixed it for me was to connect the standard micro USB to the Touchpad and use the standard HP charger unit. Then repeatedly remove the big USB from the charger, wait about 5 seconds then plug it in, wait about 10 seconds and repeat the cycle. After about twenty goes I was rewarded with the battery low icon and it started charging again. I think the theory behind this trick is that when you first plug the power in the battery gets a bit of charge before the circuits kick in, detect very low battery and stop the charging cycle. Doing it enough times gets enough charge into the battery to kick start proper charging.
Now I am not saying this will fix your problem but it might be worth giving it a go.
To prevent myself ever getting into this state again indavertently I now have Tasker set up to shutdown the whole device if the battery level drops below 8%.

To prevent myself or more importantly my daughters tablet ever having this problem I have now purchased Tasker as recommend by yourself and others. But cannot yet figure out how to setup an automatic shutdown, if you have the time could you possibly advise how to do it . I have read the guide but am struggling any help would be appreciated.
Thanks

In Tasker add a New profile and give it a name like Battery_Low
Choose State and then Power for the profile.
In Power choose Battery level and set From to 0 and To to say 8%
Set New Task and do Add give it a name like Shutdown and then pick the Misc category
Choose Reboot and set Reboot type to Shutdown
All done. When battery level drops to 8% or below then Tasker will shut the tablet down. Note it will do this without warning. I think one could probably arrange a pop up warning first but I preferred to keep it simple.

I have tried this since your post - thanks. No luck, but will continue to try. I found a post online with disassembly instructions. I think I may try pulling the battery. Looks rather easy... with the right tools.

The only way I know is to put it on a Touchstone and after an hour or so it Will come back to life. All thanks to Reverand KYLE. His site is well worth checking out.

Help! My Samsung Galaxy Note N7000 seems bricked.

Hi Guys!
What is the definition of being Brick?
What happened:
It was low batt at 1% so i switch it off and plug in the charger. The moment the battery appeared, i tried to start it. However, i did not observe the subsequent event, and my phone now neither charges (no heat), not detected by computer nor respond even after i put in a working battery from another N7000.
I had been on paranoid android for 3 weeks.
Suspect power low or power died on boot up.
Any solutions?

Try another charger and another cable.

Same thing once happened to me.
Since it worked for me i m posting here.....for many it wud be ridiculous but u never know what to do in such cases.
I cleaned the surface of charging points by a small pin i.e. the port of micro usb where you insert the charger cable. Then i tried charging the battery. Wonder......it worked for me.......

You should try to remove battery and let your phone without any power source for a several minutes.
Then put battery back and try.
Try long press the power button (30 seconds) just in case.
If it don't work, try to plug an USB JIG to see if your note go to download mode.

[Q] HP TouchPad Dead - Homebutton Flash left -> right HELP :(

Hey Guys,
yesterday my Touchpad was shut down because the battery was empty. So I charged it over the night. But today morning it isnt starting like the other times. The homebutton is flashing from left to right... Home + Power button dont work. Sometimes if I do the trick "cable in, power and homebutton holding, cable out still holding" came the battery with the question mark for 0,5 seconds... Is it dead?...
Charger is hp original. Cable not.
please help...

No it's not dead. We're lucky, the tp is hard to kill, thanks to webos .
Charge the tablet to 100%. Use the wall charger. If you have a touchstone, you can use that too.
You might have to leave it charging for 24 + hours.
Once charged, hold power and volume up buttons together till you get the screen with the usb symbol. Once you have that, follow this guide: http://forum.xda-developers.com/showthread.php?t=1426244
It's a pita, but it works. If you have a problem with novaterm, there's a good workaround on page 12.
Good luck.

Thanks for your answer. How I can know if my tp is fully charged?
And the combination dont work. No reaction.

You have to let it charge for a long time. It takes a real long time to recharge after it's gone to empty.
Make sure the charger is alright (sometimes all it needs is a twist to set it right).
If you can, change the cable.
The tp will be charged enough when pressing the power and volume up buttons together brings up the usb symbol (webos recovery). Hold them for over 15 secs.
Good luck.

The home button flashing left to right means the battery is charging but has insufficient charge to boot.
You need a charger, preferably the original one, but any mains/AC charger that kicks out 2A at the right voltage will do.
Leave the TP charging and eventually it should automatically boot into the default OS - may need 24 hours or more...
Cheers

Did you get this to work?
Based on your post count, this is probably a stupid question but:
You tried charging in an outlet (not through computer), right? Any under-the-hood work makes my Bionic run hot and burn through the battery.
More technical: I read somewhere that someone upgraded to windows 8 and fastboot stopped working. Windows 7 fixed the problem (if you're saying that fastboot is the problem, not Vol - & power button recovery mode).
Were you in the process of rooting?

I am kind of having the same problem. I recenty got a droid bionic where I had to replace the LCD screen and battery since when I got it it did not have a battery with it. I got an NON-OEM extended battery and every thing was working fine for three days. In that time I was able to upgrade everyting to the latest software, fireware, and Android version (4.1.2 JB) but after those three days the phoe woould not power on. When I plugged it into my computer and tried, the white power light would just blink at me. when I unplugged it from the computer and tried it would not even come on. I thought it was the battery so I sent it back and got an OEM extended batter and a OEM dock/charger. When I got everything I plugged it all in and the screen came on with the Motorola M logo and then showed me a picture of the battery at 5%, so I let it charger over night. In the morning I pressed the power button while still plugged into the charger, the phone light up saying the battery was at 100%. So I took it off the charger and tried to power up. Nothing happened. I plugged it into my computer and the white power light came on and stayed solid but still no power-up. I just tries the Volume Up/Down power while plugged into the wall charger and I can get to the recovery screen and try the normal boot up, I get the Motorola M Logo screen, I just now tried recovery and the little Droid just showed up with its stomach with a red triangle and an ! in it and is just sittin there. and now it when back to the Motorola M Logo screen then the battery screen. Does this mean mine is bricked as well? Please some one help.

Bumping because of no help yet. I can access the recovery screen but does not seem to help any, it also has to be plugged into the wall charger for this to happen but I can not power it up whether it is plugged in or not. Please Help someone so I can get this figures out.

Alright strange thing to try, plug it into your computer, while plugged in take it the battery, give it a minute and put it back in while still plugged in.

Did as you suggest but when I took out the battery. the white light stayed on. Still could do nothing. Waited 2 minutes, put the battery back in and still nothing. All I get is the white light staying on. I unplug from the computer, the light turns off and still nothing, not even the recovery screen will boot up.

Can you get to the fast boot option by holding both volume buttons and power

As long as I keep it plugged into the wall charger I can. When I go there it says "Battery Low Cannot Program Connect USB Data Cable. But as soon as I unplug the wall charger it shuts off and I can not get back to fast boot. When I plug it into the USB cable and plug into the computer, I can not get to fast boot. I just check and it says my battery is at 100%. but when I first plug it in it says 5%.

Your gonna need to charge your battery with either an external charger or the usb charging hack before you can perform an fxz on it

Time to replace battery?

Hey all. I haven't used my Touchpad in about 4 years. I forgot what version of Android was on it when I last had it. Finally found it in storage. It's missing a charger but I've been using a phone charger and the home button light is doing its thing alternating back and forth. It's only been a few minutes but I've tried to turn it on and nothing is coming on. I don't remember if there's a charging screen or not when it's powered off and charging.
The touchpad itself is in pristine condition again I just haven't turned it on in a few years but want it for leisurely reading ebooks and comics.
Does this sound like a battery issue? I was gonna wait an hour or two to let it charge some more to see if it will come on.

HP Touchpad never dies, just sleeps deeply

It might be fine but you may need to charge if for 24hrs and fiddle with the buttons if its fussy. Some info about all the below and try to use the origial charger if possible, the voltage it puts out is best for the tablet, read thread about it here.
My HP TouchPad won't turn on is it bricked?
-If your battery has been fully drained, then you may need to leave it charging for a full day
-When the battery is fully drained it can take the TouchPad a longtime to reach even the lowest battery level
-The USB cable does not transfer enough power to effectively charge the tablet
-You must use the wall plug when charging the HP TouchPad
-After charging the HP TouchPad try the following key combinations
key combinations to turn the HP TouchPad off or on when not responding:
-Hold down the Power and Home buttons together for 30sec
-Hold down the Power button and click the Home key 14 times
-hold down, home + power + volume down for 30+ seconds

So turns out it was working. Opened Chrome and last time I used it was January 17th 2014.
The battery life has been really good today I've been using it to read ebook PDF files and also listen to music.
