[TouchPad General] HP_TOUCHPAD:
You are very welcome, I only made a Live CD image with all the working files for the process to work.

In the second post, I explained what the tpdebrick does:

https://xdaforums.com/t/hp-touchpad-debrick-linux-live-cd.4189245/#post-83906949

If bootie on the flash disk has been damaged or corrupted in such a way that booting into recovery mode is not possible, the Pre is still not "bricked" as the OMAP3430 processor in the Pre provides for a mechanism to boot code from its USB interface.

The same applies to the HP Touchpad.

The bootie, is the same as the Bios on a computer. Is the built-in core processor software responsible for booting up your system.

if the bootie gets damage or corrupt, the Tablet will not boot even with a perfectly healthy and fully charge battery. Nothing works, no LED light, no Display. Is all dead no matter what the user does to it.

When the tpdebrick is apply to the Tablet that has a good battery and got some charge, the process will finish with no errors and it will boot up.

If the Tablet's battery is completely depleated, it can not boot up or finish the tpdebrick process. There is no electricity to boot the processor and the display.

Tpdebrick does not fix a physically damage battery or anything related to the battery.

Tpdebrick reflash the bootie, the software responsible for booting the Tablet.

I`m here again after years with good working touchpads. But now I´ve got two of them doing nothing. Even usb connect recognition (on PC) doesn´t work. Both tablets stood on touchstones for years....
[TouchPad General] HP_TOUCHPAD:
The information you are providing is too general and does not mention anything in specific to provide any help.

1. Good working touchpads ( you are the first owner ? ) or second hand?

2. Stood on touchstones for years. ( Did both stop working while there were charging on the touchstones? ) or was put away after years been on the touchstone?

3. How both tablets became unresponsive? ( while been use and charge? )
[TouchPad General] ranjib:
1. Good working touchpads: they worked without problems for years.

2. Stood on touchstones for years. All of the sudden stopped working. No response, both of them. I have a third one on a touchstone, this one ist still working fine....one of the faulty ones is now connected by wire to a charger, trying to get something in there.

3. How both tablets became unresponsive? Smply by standing there, showing a daydream clock. both have Android. Last JCSullins version.

In the past I have rescued two touchpads with the help of JCSullins utility, that worked fine. But these touchpads gave life through the usb bus. Now there is no response. Nothing. Every pc here does not recognise the usb connection. Tried with different usb cabes. No chance.
[TouchPad General] HP_TOUCHPAD:
This has been my experience, it maybe the same or not.

I have two tablets running 7.1.2, both on a touchtone (wireless charger), this has happened, it is rare but possible.

( Problem )

The Tablet screen is all dark, nothing is on, but is on the charger.

Tablet is not responsive, just dead. Pressing power does nothing.

Tablet is frozen, somehow either got into a deep sleep or the OS froze.

When the tablet freeze, it will not take charge either by wireless of USB and the battery will get depleted.

What I have done:

Hardware RESET:

Press at the same time Power (1), Volume Down (2) and Home (3) at the same time.

Hold all three keys until the tablet reboots, it could take a minute or more holding all three keys.

If there is some battery left the electricity plug will show and is ready to charge.

If nothing shows up, then connect to USB or Wireless while holding all three keys.

Is very important, if the Tablet freeze the screen will be active, battery will get drain and then goes dead but still frozen.

The user will find a dead battery, will try to charge it, but it will not take charge until is reset.

Hopefully this is your case, give it a try or multiple tries and see if it helps.

Good luck!
[TouchPad General] ranjib:
Windos and Linux can´t recognise any of the two TPs. No reaction, no Qualcomm devices detected. I will try to carefully load the TP by usb bus... got the devices on charger now for days. Nothing changed the state.
[TouchPad General] HP_TOUCHPAD:
You did not mentioned if you tried to do the hard-reset process.

The Tablet must turn on and be place in the WebOS recovery mode or Recovery TWRP to be detected by any PC.
[TouchPad General] ranjib:
Off course I did the three button thing as recommended.... will wait a longer time to charche by pc usb port (at low-er current..).
[TouchPad General] HP_TOUCHPAD:
The Tablet must be charge with the original charger or wireless, it needs the proper amount of energy for a jump start.

After the Tablet boots, then a lower charger can be use, but not at first.

Did you tried the hard reset while connected to the original usb charger? ( all keys press until the home LED comes up )

For the battery to take charge, it must be in a warm environment, a temperature over 85 F.

Also interment charging can wake up the Tablet, can be done easier with the touchstone. Place it on the touchstone stand for about 10 seconds, then remove it, wait 5 seconds then place it back and repeat 10 times. Do the cycle as many times as you can.
[TouchPad General] ranjib:
Ahh thank you. Again this is what I already thought....to put the charger on a smart wallplug and let google home blink it on and off....

Now there are two of my three faulty Touchpads definitely with broken batteries: there is a spot visible on the screen, caused by a swollen battery.
[TouchPad General] HP_TOUCHPAD:
Every time the plug gets connected to the wall there is an extra burst of electricity that gets to the battery, eventually providing enough charge to wake up.

I will not suggest to keep charging those Tablets, get a replacement battery:

https://www.ebay.com/itm/154110698362?hash=item23e1b6a37a:g:AFkAAOSw0NNgr0SF

Also look at other Tablets for sale:

https://www.ebay.com/sch/i.html?_from=R40&_nkw=hp+touchpad&_sacat=0&_sop=15

If you know your way around you can connect the Tablet permanent to the wall outlet, just like a PC. No need for a battery. The old battery connector is need it, so keep the old battery.
[TouchPad General] ranjib:
This is exactly what I did. Two new batteries are on the way, a second hand used Touchpad is bought via ebay....I´ll try to exchange the batteries.
[TouchPad General] HP_TOUCHPAD:
Great, now you will open the Tablet and replace the battery.

Do not worry if the plastic/metal clips break or comes off, the screen will close with only a few intact.

Very important:

After installing the new batteries, check the battery health, just because is new does not mean it has 100% capacity.

Also check all the tablets, you will know the true remaining capacity of the batteries.

Look at this post on how to do it:

https://xdaforums.com/t/hp-touchpad-poweroff-prevents-battery-drain.4002265/#post-80993173

Good luck!
[TouchPad General] ranjib:
Thank you. In the meantime there are good news from here. I managed to get the one with good battery to come back to life after the "pulse" charging method. Left it all the days on a charger cable, now it´s running flawlessly again. Booted afterwards with tptoolbox, flashed a6 firmware, checked all partitions. It now stands on the touchstone, working.
[TouchPad General] HP_TOUCHPAD:
The intermittent or pulse charging always works for me. Both of your tablets are fine and will work as before. Both of them froze with the display on and drained the battery to below the minimum to start taking charge again. Is up to you, but the other tablet will also boot if you do the pulse process, just do it when you are home and keep an eye on it. Thanks for the update and good luck!

Hi guys i get this error when i try to boot the live cd. Tried using unetbootin and rufus too any help?
[TouchPad General] HP_TOUCHPAD:
It is very important to select the correct settings when making the bootable USB from the ISO.

Also, the Bios on the PC must be set up to boot using Legacy, not EFI. This is an old version of Ubuntu and does not include an EFI boot option.
[TouchPad General] ankurcshah:
I used the default settings from netbootin and rufus according to the screenshot you had here. I did set the boot to legacy
[TouchPad General] HP_TOUCHPAD:
The ISO for the debrick live CD is base on Ubuntu 12.04 LTS 32-bit, the same version that jcsullins used to make the script. This provides the original compatibility to work 100% as intended.

Ubuntu 12.04 LTS came out on April 26, 2012. To boot properly on real hardware, I am guessing a PC must be from the year 2010 to 2015, also depending that has generic or supported hardware by the kernel ( drivers ). Your error message is related to the storage ( not able to find the media ). Bios boots and recognized the USB, but Ubuntu does not and fails to load the drivers that are built into the kernel.

Test the USB drive on the same PC but using a virtualization software like Vmware player, VirtualBox or qemu. Use the proper settings for Ubuntu ( 32 bit , Bios legacy ) and add basic components, it will boot with no issues. But the script connect and disconnect the Tablet from USB and that could be a problem with a virtual machine as the USB disconnect from the guest and connects to the host. It is best to use a real PC.
[TouchPad General] ankurcshah:
So i did everything and i had a hunch so i used the latest linux 20.4 and it booted fine but the same (and different pendrive and slots) on the linux live cd just refuses to boot and throws the same error to me like the pic in my previous post. This was my last hope of reviving the tab. Im still gonna keep trying..
[TouchPad General] ankurcshah:
I managed to get it to boot on the vmware but i ended up with the same error i got in the older version sadly. Attaching the picture for your reference.
[TouchPad General] HP_TOUCHPAD:
Did you look at the youtube video?

That error shows, but then the process keeps going.

Did the touchpad USB connection got disconnected from the guess PC?

I do not recommend using a virtual machine as the USB connection gets disconnected and it will go to the host PC terminating the process.

Why do you think your Tablet is brick?

The debrick process re-flash the bootie ( which is the equivalent to the PC BIOS ). It does not do anything to the battery or controller.

If the BIOS on your PC is damage, it cannot boot. Is the same for the HP Touchpad, the bootie gets damage preventing the tablet from booting.

This is the time on the video that shows the file of the bootie-topaz305.bin
[TouchPad General] ankurcshah:
Sorry this tool just doesnt boot on my pc with pen drives. I think my tab bricked when i changed dpi by mistake and i left it for a long time. I have given up on fixing it. Thanks for your help
[TouchPad General] HP_TOUCHPAD:
Ubuntu 12, would not boot properly with new hardware that requires special drivers.

The Tablet can not be brick by any Android settings. If any changes are done in Android and the Tablet will not boot up, then go to TWRP Recovery and reinstall Android.

If the Tablet is left for a long time and not getting charge, the battery will go into a deep sleep preventing from waking up (recharging). That applies to all devices that are power by lithium batteries.

The Tablet must be charge by using the original charger or equivalent in a warm environment of above 80 F.
[TouchPad General] Pierre38:
Hello,

Thank you a lot for what you did.

I followed all your process and get stucked at "checking A6 Firmware" step (see the picture enclosed).

I tried several times with 16, 32 & 62Gb recovery. I waited more than 30 minutes, it's still frozen at this step.

Some change since I tried to debrick my TP, the home bouton blinked before when I charged the TP but it's not the case anymore.

Any Help on this issue ? Thanks in advance.

Edit: My computer now see the TP as an "Android" Device.
[TouchPad General] HP_TOUCHPAD:
Look what happens next at the YouTube video at the following time:

Then the bootloader bootie gets flash:

The bootloader bootie is what can get damage and prevents the Tablet from booting up even if it has a full charged battery.

But a Tablet with a damage battery will not boot up no matter what. Same as in your car, it can not start if the battery is dead.

If the home button blinked, then the Tablet is not brick, but the battery is completely dead and needs to be charge.

The PC will only recognize the Tablet as an Android device if it boots into TWRP recovery or Android.
[TouchPad General] Pierre38:
Ok thank you for your quick and detailed answer, I'll change the batterie.
[TouchPad General] HP_TOUCHPAD:
You could try to revive the current battery by:

Charge using the original HP charger or equivalent. ( is a MUST )

While charging, the room temperature must be above 80F. Lithium batteries take longer to charger in cold weather.

Do intermittent charging, plug charger to wall and unplug, or use an extension cord with on and off switch. Every time the charger is connected, there is just a little more power getting into the battery.

While charging, press the home bottom on and off about 10 times, this could bypass any warnings or errors and allows booting.

It could take of two 2 weeks to revive, good luck !
[TouchPad General] Pierre38:
Ok, I spent my entire evening doing that.. I hope It'll be fine! Many thanks
[TouchPad General] Pierre38:
Hello,

I continue my researches about the Touchpad Battery, hope it will be helpfull to understand the malfunctions and help others.

I made some voltage measurments of the battery and several tests.

I only had a small current measurment while connecting directly the DC charger with the Battery, it said 0.79 mA (see picture enclosed) which is very small but sign of life ( sign that the battery slowly take the charge ? and explain why it can take two weeks ?).

Voltage between cables green and blue is 3.8 V.

No resistor measurment between the two red cables and the two black cables, means they are connected and one cable of each is ok ?

We tried to remove the red & black cables only and charge them while the other cables were in place but no results (see picture enclosed), the objective was to bypass the battery management system by making him believe that all is ok while we charge the battery externaly. No success.

Can someone explain what are the Blue and green cables (and also the yellow ?) and why I measured 3,8 V between the blue and the green ?

When I connect my charger normaly, I Saw 1,8 W from the power outlet, 2V between Green and blue cables and 9 mV between Red and black, very small and it means for me that I should directly charge the battery using electrical wirings.

Good day

Pierre
[TouchPad General] HP_TOUCHPAD:
Take a look at this post:

https://xdaforums.com/t/hp-touchpad-poweroff-prevents-battery-drain.4002265/page-5#post-81075317

The output of the charger must be of 5.3 volts 2.0 amps. The Tablet can be use with no battery if the proper power supply is connected.
[TouchPad General] xdause:
what charger do you recommend to power up the tablet with a dead battery? I have several chargers capable of 2amps and none seem to turn it on.
[TouchPad General] HP_TOUCHPAD:
To charge the battery, it must be 5.3 volts 2.0 amps

To power up the Tablet with no battery, the AC adapter needs to provide the same as the battery 6A, the attached picture is of one that I bought, but all my tablets are working.

Your battery seem flat, which is a good sign.

Take a look at some videos:

[TouchPad General] tonyjobson82:
In case anyone else finds this post.

I was having an issue with it hanging at "Checking A6 Firmware" .

I suspect this was caused by my laptop network interface flapping during the SSH of the A6_firmware.

The TouchPad is flashed via USB network so this flapping port will have killed the upload.

I fixed this by editing the tpdebrick script from ~/tpdebrick-v005/tpdebrick add "sleep 20" at line 547 just after the

echo "Checking A6 firmware..."

sleep 20

This will give the laptop time to recover the network interface fully before the SSH command runs and pushes the firmware to the tablet. Mine was crashing during this step due to a flappy network and is probably host hardware dependent. hope this helps. T.
[TouchPad General] HP_TOUCHPAD:
Thanks for taking the time to post a solution.
[TouchPad General] Silvers91:
Hey there guys, glad to see this tablet is still receiving support. I found an old one I had put away in storage and haven't used it since 2018, but it's no longer turning on. I no longer have the original charger it came with, so I'm only trying to charge it with a regular 5v 2a smartphone charger, but it doesn't show any sign of life. The only thing I noticed is it starts to get a bit warm (the charger also), but still no sign of life. It was left connected to the charger for more than 24H. Any tips I could try to revive the battery without having an original charger? Thanks a bunch!
[TouchPad General] HP_TOUCHPAD:
It can be any charger as long as it has the same specs of the original charger of 5.3 Volts 2.0 amps.

[TouchPad General] tenmachi:
Can confirm - I spent a solid week trying to get charge into an e-cycle rescue TouchPad with a 5V 2A charger, and... I was able to get *some* in, but not enough to get much done. Mind you, that's as much to do with the other problems it had...

This TouchPad in particular had the much-disliked [?] battery icon when it finally did power the screen (after I got a Touchstone charger from eBay and gave it some time). I found out the hard way this liveCD is hard to get to run on anything modern; even if you can get it past UEFI systems' insistence on trying to do things that way (CSM works!), it's still an old distro of Ubuntu so it didn't play nice with my GPU. I eventually resorted to breaking out an HP Pavillion ze2000 that I keep around for running retro games... some travails with a USB cable that should've been fine, but wasn't, and another one that was a little shaky on its connection, and I got the debrick done.

On the subject of travails...

...I would like to give an enormous hat tip to @tonyjobson82 for working this out and sharing the method. It turned out to be necessary for my debrick to finish.

Last, but most certainly not least, THANK YOU VERY MUCH @HP_TOUCHPAD for putting this liveCD together. It made life a heck of a lot easier on me in getting this kid back on its feet!
[TouchPad General] HP_TOUCHPAD:
For future reference, the original charger specs: 5.3 Volts 2.0 amps, is very important to use exactly the same to revive a dead battery. Once the Tablet is running, any charger will do as long as is always charging.

That battery icon means " No Battery detected or damage ", but the Tablet is not Brick. If any graphics or lights comes on, the Tablet is not brick.

Look at this guide: https://xdaforums.com/t/hp-touchpad-novacom-repair-android.3960435/

That is correct, the old Ubuntu version does not have the drivers for the new hardware. It is best to use an old computer. If not available, it can be used as a virtual machine, but the user needs to be aware that the USB connection will be disconnected from the guest machine to the host. Some settings must be selected to prevent that on the virtual machine software.

Very important, the USB cable, make sure is not broken and that supports data.

That extra time helps for some hardware to finish the process.

You are very welcome @tenmachi, and also thanks for posting your experience on reviving a Tablet that was set to be recycled.

The Tablet or any smartphone can be used without a battery. Even if the Tablet's battery is very low, it can be use as long as is charging.
[TouchPad General] ankurcshah:
Tried reviving it again but it seemed to keep getting stuck here

So I followed This method to get past this issue and I was successful but I am in the same boat as him now, it gets stuck at waiting for fastboot.
[TouchPad General] HP_TOUCHPAD:
This is from the link you provided on RootzWiki:

(((( I can't force it with ADB as ADB does not recognise QDL mode as a device.

As I understand it this means that my TP has residual charge, but not enough to enable any other mode than QDL until I can get some more charge into it, which I cannot do. ))))

The Tablet need enough charge in the battery to run the CPU, uploading code to the Tablet's memory does not charge the battery or will make it turn on.

Are you using the original charger?

If any lights turn on when connected to a charger, the Tablet is not Brick.
[TouchPad General] ankurcshah:
I am using the original charger and no lights turn on when i connect it to a charger, when i connect it to pc it does show that the tablet is in EDL mode (Qualcomm HS-USB QDLoader 9008)
[TouchPad General] HP_TOUCHPAD:
What happened to the Tablet before you tried to boot it?

Was the Tablet been in use?

When was the last time it was fully charge and working?

It is very important to know the battery status before doing any software troubleshooting, for the code to work the CPU needs electricity to execute it.
[TouchPad General] ankurcshah:
I honestly don't remember when it last booted up and it was fine. it's been over 6-7 years for sure. There's just nothing displayed on the screen when I plug it in or anything. I have another 5v 2a charger and have plugged the tablet in it to charge for a few days.
[TouchPad General] HP_TOUCHPAD:
Well, it is obvious that the battery is completed depleted and may even be damage. Trying to do a Debrick is not going to charge the battery.

I just found out that I have a Tablet that is not booting because the battery is fully discharge, the light does turn on when connected to the charger. I am going to do the Debrick on it and see if it finishes.
[TouchPad General] HP_TOUCHPAD:
My original Tablet today was completely dead, it was not booting.

I placed it on the touchstone and the light started to blink, then I decided to replicate the issue of doing a debrick on a Tablet with a dead battery.

The attached image is the screenshot of the last command from the process, also all the code is here as well.

The debrick could not finish due to the dead battery, so I placed it on the touchstone but this time the light does not turn on, it is all dead.

Can't paste the code here due to limitation of character size, it is in the text file.

I am going to leave it charging and see what happens and will update later.
