Update to the previous post.

The Tablet was place on the Touchstone charger from around 2:35 pm until 6:00 pm. Doing a hard reset or pressing all keys did not do anything, no lights came on while charging, it was like completely dead. I checked the back of the Tablet, and it was warm. I decided to do the Debrick process again to finish the process from before that did not complete successfully due to extremely low battery.

This time all finished and the battery shows at 0 percent, attached is the screenshot and also all the text from terminal.

Then I place the Tablet on the touchstone and the light came on, after about 15 minutes on the charger, the low battery icon with the red line came up. Then after another 15 minutes it booted into WebOS, and it shows the battery was charge at about 5%

This process can be replicated as follows and is the reason of so many "Brick Tablets after doing the Debrick"

Only try this with a Tablet that has a good battery or at least will take charge after getting completely discharge.

1. Let battery discharge, when connecting to charger, will only show the light on moving from side to side.

2. Disconnect from charger ( battery is very low )

3. Connect to PC and start the Debrick process.

4. When the process sends the command to reset the device (tablet), there is not enough battery to boot up.

5. Error Waiting for fastboot mode ... fastboot mode not found ( Aborted )

6. The process did not finish, the Tablet is now BRICK. Placing the battery on any charger does not show anything, it is all dead.

To Debrick and finish the process.

1. Charge the Tablet with original charger or equivalent only for at least 6 hours. The back should feel warm, that means the battery is taking charge. Tablet should be in a room of 80-90F otherwise is not going to charge and feel like an ice cube.

2. Connect to PC and run the Debrick process, this time should finish and display the battery percentage.

3. Start charging.

Very important, doing a Debrick on a Tablet with very low battery will cause it to get BRICK. Then there will be no lights showing when connected to charger.

That's what i am doing now. Put it in charge. Lets see how it goes

Hi!

Im so glad to see the last post was dated recently so the topic might be still active somehow. Im having problem with 2 TPs with white battery and question mark issue, i had 1 TP about a year ago which left with dead battery, i just changed the 2 cells, it got battery question mark then i used TPdebrick it without no problem and it worked as normal and it was end up in the my storage since then. About last week i got a second one which came in parts but i can still see that it can boot up to the battery question mark also, i went to get the first TP to get the battery to that new one (2nd one came without bat) but due to long time the first working one now with the swollen battery :(.

I replace the 2 cells again then now i have 2 TP board has the battery with question mark but the problem is i cant not get either one done with TPDebrick due to QDL mode not found. The replaced battery cell are fine though because i can boot up both of them to the screen with question mark and it can stay there for very long time so i assume the battery got enough charge to stay on. I tried 2 different computers 1 is an desktop with window 7 64bit and the other one is an macbook air 2017 version, but both showed QDL mode not found after i held down power+home+voldown button combination and i completely forgot which computer that i did TPdebrick with the last time :(. Can you guys have any suggestion to overcome this problem i would much appreciate it. Thank you!
[TouchPad General] HP_TOUCHPAD:
Look at this guide that shows the meaning of the different boot icons.

https://xdaforums.com/t/hp-touchpad-novacom-repair-android.3960435/

If the Tablet displays any icon or show any lights when connected to a charger, then the Tablet is not brick. If the debrick process is performed, then it will get brick as is mentioned on post #80

https://xdaforums.com/t/hp-touchpad-debrick-linux-live-cd.4189245/page-4#post-88859103

If this is the icon been display:

The Tablet is booting and is not brick, the original charger must be use or equivalent of 5.3 volts 2.0 amps.

Try to load the Toolbox by jcsullins and flash the A6 Firmware.

The tablet must be on a charger all the time, if place away it needs to be checked every month to prevent a total discharge.
[TouchPad General] tthufo:
Thank you for such quick response! I have not tried the TPToolbox before, i just make liveusb one and it's booted fine, i'm watching the video now and when i connect the TP to computer and run the a6 flash but it said unable to find device so my question is do i have to place the TP in which state before connect to the computer: The boot up screen with battery question mark or the download mode screen because i can not get into that, just the white bat question mark one. If i've mistaken somewhere and miss some important information then please give advices and thank you for your patience :)
[TouchPad General] HP_TOUCHPAD:
The Tablet must be charge with the original charger, otherwise nothing will work. Also, it needs to be charging for up to a week in a room temperature of around 80F.

To place the Tablet into WebOS recovery mode, press at the same time:

Power and Volume UP (key closer to Power). This icon should come up:

I can not test if it will show when a battery is not detected, as I do not have a Tablet in that condition.

My advice is to charge the Tablet until the battery takes charge. Also, if you replaced the battery, make sure the inside connection are properly connected, if the issue is hardware (physical), no code or software can fix it.
[TouchPad General] tthufo:
Thank you sir, you're so dedicated for this whole topic. These touchpads are so tricky and unstable with the firmware and battery communication, i spent quite sometime with both TPs and got frustrated try to revive either one, especially the first one that already brought back to life once now refuse to breath again. That one now have a blinking home light button even without the cable plugin and sometime it just boot the HP logo and then jump to the battery question mark one. Both refuse to get into QDL mode as i read somewhere in the rootwiki comment that some just cant get in QDL, but the funny thing is the first TP i got it back to life a year ago with TPDebrick 004 and it got in QDL mode with button combination just instantly and now it wont pass to the loading step after "Release button now" message. I got all checked up with volume button up and down connection with electricity meter. I'm about to move on to play with other devices then, took to much time and frustration though )). Thank you for your time sir, much appreciate!
[TouchPad General] HP_TOUCHPAD:
You are very welcome!

Every tool is available to fix problems related to software, also the Tablet is very easy to take apart and fix as everything is hold together with basic screws.

Both of the Tablets are not brick and functioning as it should. The Tablet's turns ON to the bootie (BIOS) checks for all the internal components and detect that the battery is not charge or have problems and displays the diagnostic results on the screen. When a Tablet is brick and battery is charge, nothing works becuase the bootie (BIOS) is damage and that is why of the debrick process.

I already provided the link of the issue when a Tablet can not finish the debrick process, the battery is completely dead.

If there is no electricity in the Tablet, the processor can not work and the software will not run.

Both Tablet needs to be place on the original charger and left there for over a week in warm temperature for the batteries to wake up and take charge.
[TouchPad General] tthufo:
Hi! I just found out the problem with QDL mode is due to bad USB cable although it was a original one that came with an old Pre 3, i just tried with other cable that lying around and see QDL mode in window and can run the debrick process but still got stucked at netchip mode ... for most of the time. There was one time it got to the checking a6 firmware but it hung again, as i read this is also a problem with usb connection i suppose, the netchip mode echo one is the script tried to find the usb connection and the checking a6 firmware ... is in ssh mode try to connect to TP for checking before proceed to flashing the firmware right. All came back to me now as i did the debrick before with some modification as i did the debrick in ubuntu 22.xx as it required some different acceptable algorithms in ssh-key when ssh to TP host for update a6 firmware and bootie.

It just got stucked at "access to the 192.68.7.7 host (Touchpad) failed" after ping to TP host everytime, i guess the ping process was started before the connection from TP as 192.168.7.7 host established connection to the computer so i just make an duplicated .sh tpdebrick file and copied those code from "echo "Waiting for ping check... (may take 1-2 mins)" to the end and re run that sh file because now the ssh mode is in order to work as the TP appeared as an network connection to ubuntu. After that everything went well with no hassle and got it charged up and booted fine although with an lower amp charge rate, i'll revive the last one as well then will be careful with the battery usage or just perform the debrick next time as i got all info noted just in case )). Thanks for your info and encouragement sir.
[TouchPad General] HP_TOUCHPAD:
If the USB cable is bad, then is not going to charge the Tablet. Any USB cable will work, but also make sure that it provides data connection as well.

To revive a dead battery, the proper original or equivalent charger must be used.

If you use a good working USB cable and a good charger, the Tablet will boot with no problem.

Congratulation for trying and learning!

Always keep the Tablet charging and in use, it will last forever.......
[TouchPad General] tthufo:
Thanks sir. Can you give me some tips how you maintain those TPs of yours )). I also have the hobby in collection, just enjoy poking around with faulty devices but cant spend time for maintenance though.
[TouchPad General] HP_TOUCHPAD:
To maintain, the battery of any device requires the same process as your car, whether it is gas or electric. " USE IT "

Once the Tablet is fully charged, flash your favorite ROM and give it some use, like music streaming, picture frame, weather station and many more..

If it is not going to be use, then charge it and check on it every couple of months and recharge as need it. The Tablet can turn on by itself and completely gets discharge and the battery will eventually get damage.

Good luck!
[TouchPad General] DoubleStuff:
So here is the story of my "bricked" touchpad....I have not used my touchpads in like 4 years. Then somebody from work wanted me to load their touchpad up with Android again, I had done it for them previously ( 2019 ). So I brought my touchpads out of storage and began to experiment, and after a full night on the chargers they all booted. One had KitKat4.4 from jcsullins. So I decided to flash Evervolv v9 Android PIE by Elginsk8r, so I used the @HP_TOUCHPAD method

I flashed the Automatic_Wipe_All_and_Create_Android_with_1GB_Swap_Partition.zip, and then the ROM ev_tenderloin-9-userbuild-2019.08.30.zip, and then the HpTp_MAX_1836_CPU_Universal_Optimize_Swap_Evervolv_v9_elginsk8r_Pie.zip and after I flashed them I got this "pale blue" screen. So I thought to myself maybe this particular TP can't handle the 1836, so then I was able to boot back into TWRP with the "3 finger salute" Power, Volume Down, Home, and flash the lower one 1782. So I got the "pale blue" screen again, but this time the "3 finger salute" did not work. I did not think the battery is dead because I was just working on it, but I charged it for a night, and it became warm, and tried the Debrick005, and keep getting the error "QDL mode not found" while doing the "3 finger salute" while debrick005 says to for 30 seconds. I am not convinced its "bricked", but I can't do anything to it.

So I have these questions:

1) What does this "pale blue screen" mean?

2) Is it possible maybe the home button is not working anymore, so the Touchpad does not sense the "3 finger salute"?

3) Does anybody have another theory of this "pale Blue" brick?
[TouchPad General] NautTboy:
over 10 years i bricked mine after tried to upgrade to CM?? and Left it drained too long.

POWER+DOWN+HOME does not do anything

Charge over night(original charger). Yes charger is good, have couple working TP

Tried the new LIVE CD debrick 16 and tried 32

first message was: "Check_File Not found.

hold down power+down+home for 30 sec"

Held it for over 1 minutes and now my finger is stuck :-p and

is this unbrickable?
[TouchPad General] HP_TOUCHPAD:
Welcome back @DoubleStuff after the 4 years of hibernation from the forum..!

The Tablet running WebOS, the CPU was set around 1200 from factory. The White 64GB 4G was set at around 1512.

During WebOS time, the CPU was overclock all the way to 1836. When Android was ported, the default overclock of 1512 was used.

Not all Tablets can handle even past the 1512. All Android ROMs by default use 1512.

In this case, flash the original Android 9 boot image and see what happens, but it can be the CPU speed because the Tablet boots into TWRP which uses the 1512 speed.

The Tablet is not brick, because it does boot up. A brick device does NOTHING, not even the screen turns on.

Do you mean, once the Tablet is turn ON, it automatically shows the Pale blue screen?

Does the Tablet boot into the mooboot screen?

My guess is: That Tablet can not handle the CPU speed of 1782, try 1512.
[TouchPad General] HP_TOUCHPAD:
A drained battery is not a bricked device, and doing a software flash is not going to miraculous charge the battery in a minute.

I get it, there is a lot of information about this Tablet and is not organized properly that users will be able to find and troubleshoot it.

It is like a disorganized user manual with 90% of the info been a guess hit and missed try.

Yes it is unbrickable, because it was designed with the ability that even if the Boot code got damage "BIOS" it is possible to be re-flash.
[TouchPad General] DoubleStuff:
Thanks for the reply, after I talked to you and HP_TOUCHPAD, I may try debrick005 again and press power+down+home for maybe 2 minutes....but I don't think my hp touchpad is bricked, I think it maybe a hardware problem.
[TouchPad General] DoubleStuff:
Hello HP_TOUCHPAD, yes its been a long time since my last post and since I have used the hp touchpad, I was a little rusty my brain needs a reboot. But I missed the nice banter of the forum, while reading the 46 pages I had a good laugh.

Did you look at my 2 attachments in my previous post? The "pale blue" screen does not change, I can press power off, it will not turn off, I press the power-down-home, it will not show the reboot screen, I press power-up and it will not show the giant USB symbol. I plug it into a PC with working cable ( as tested by my working touchpad ) and the computer will not show the touchpad icon. I tried debrick005 and it acts like its not connected, and I tried your Novacom repair, and says "unable to find device". So this might be a "bricked" table with a "pale blue" screen. Maybe I should let the battery to totally drain so the 'pale blue screen' does not show anymore....

Do you have any good advice? I thought it might be a hardware issue.
[TouchPad General] NautTboy:
What do i have to lose? Possible to take it apart and charge the battery itself? Anyone have schematic for battery pins?

My question still not answered to what is this message on LIVE CD message "Check_File not found". Is there a file call Check*** in the directory? I checked but not see any files starting with CH...
[TouchPad General] DoubleStuff:
Hello NautTboy, that error message you see is normal, my attachment post circled in green everybody gets the message.

What happens after you press Power-VDown-Home for 30+ seconds. That is the key thing.

Checkout the original post on page #1 picture#3 it has same error, "check_files: not found", so its a non-issue.
[TouchPad General] HP_TOUCHPAD:
I did look at the post, but did you read my reply? #95

My question:

You charged the Tablet, it boot up to TWRP and you flashed Android 9. When it boot into 9, the pale blue screen came up.

Is that how it happened?
[TouchPad General] DoubleStuff:
Yes I read your #95 you said that maybe my hp touchpad can't handle 1836, you said to try 1512. You are correct I flashed Android 9 with 1836, and got the first blue screen, but was able to boot into TWRP and re flash 1782 which then gave me the final blue screen in which will not allow me to reboot into TWRP, so I can't try your suggestion of flashing 1512. I believe this hp touchpad to be "bricked", but its probably not a "software brick" because like you said this device is "unbrickable, unbreakable, unbelievable" but I think its a "hardware brick" maybe the power button does not work, or home button is broken. But when I plug it into charger it becomes warm, and like I showed you, it always has a "pale blue screen" that is better viewed in a dark room.

I tried all your nice tools, debrick005, novacom repair tool, this is the first brick I had since 2014!!! But maybe its not bricked?
[TouchPad General] HP_TOUCHPAD:
If the Tablet is not properly place in the correct mode, nothing will happen.

Posted from the first page:

https://www.webos-internals.org/wiki/Last_Resort_Emergency_BootLoader_Recovery#OMAP_boot_Procedure

This is why some Tablets get "brick" corruption of the bootloader (bootie), the Pre and HP Touchpad shares the same flash disk

One situation which cannot be recovered so easily is the extremely unlikely event of corruption of the installed bootloader (bootie) stored on the Pre's flash disk.

This is an example that can easily make the user think the Tablet is brick.

On a working Tablet with a full charge battery.

Pressing the following keys at the same time until it turns off: Power + Volume UP + Home ( Volume UP is the Key to the Left, closer to Power )

Doing that will place the Tablet into TOTAL OFF, meaning:

Connecting any charger will not turn on the Tablet.

Pressing the Power key, will not turn on the Tablet.

Connecting the Tablet to a PC will not turn it on or be recognized.

The only way the Tablet will turn on is by a HARD RESET. Pressing at the same time, Power + Volume Down + Home.

If the user confused the volume keys, then it can easily place the Tablet into TOTAL OFF mode and think is brick, but not.
[TouchPad General] HP_TOUCHPAD:
How can the Tablet be brick when you flashed Android 9 using TWRP?

The Tablet booted fine, just because is stuck in a Pale blue screen does not mean is brick.

Brick is when it does not power on at ALL even with a full charge battery.

Read post #103

Remove from charger or PC connection.

Press and hold util it turns off : Power + Volume UP + Home ( Hold until it powers off, maximum 3 minutes on hold )

To Wake up, Power + Volume Down + Home ( Hold until power on )
[TouchPad General] DoubleStuff:
Well yes it flashed Android 9 with 1836 and 1782 ( previous version was CM11 ), but it went to blue screen, Android never did come up. My thinking was same as yours, that I have to go down to 1674 or 1512, but I never could because of brick.

So at that point it was "bricked". So before that it was a good tablet, but after the flash of 1836/1782, and PIE, it was brick.

I tried Power/Vol-up ( closer to home )/Home for 3 minutes, and the "pale blue screen" does not turn off.

I am curious where did you get the "3 minute maximum" rule?

I will get some duct tape, to tape down Power and Volume Up button, then maybe a weight on the home button and will leave that while I watch TV. See if it boots to "Moboot Menu"
[TouchPad General] HP_TOUCHPAD:
The Tablet does not get brick by flashing a ROM or doing overclock, it could get stuck but eventually will turn on when the battery drain.

Try it on a working Tablet and you will see it does not take 3 minutes, but less.

That will not work, it could actually damage the keys, and then it will be hardware broken.

You can leave it on until the battery runs out, then connect to a charger. Boot to TWRP and flash the stock Android 9 kernel.
[TouchPad General] DoubleStuff:
I agree Tablet usually does not get bricked by flashing a ROM or overclock, but I am just telling you the facts on what happened to me, I am just reporting what happened.

Yes I know I have done it hundreds of times what I call the 3 finger salute, Power/Vol-Down/Home usually takes maybe 10 seconds to get Moboot screen, and Power/Vol-Up/Home powers off, and does not Power/Vol-up bring up Giant USB symbol??

I am glad you replied quickly, I had my duct tape and weights all set up, and actually took a picture, but once you replied that I should not do it, I took the weight off and the duct tape off.

I will follow your advice and leave it uncharged until the "pale blue screen" goes off by itself, and try again.

One thing I know about you @HP_TOUCHPAD you are very helpful and want everybody to have a forever hp touchpad, and usually your advice is the best advice because of all the black holes you have gone through, but with brain power and study have dug yourself out of. You don't confine yourself to the 6 walls of human thought, but set others free!!! Wheeeeee.

See my attachment, please other users "DO NOT DO THIS".
[TouchPad General] HP_TOUCHPAD:
You are very welcome !

Did you try the reset with the Volume Down Key, not the one that you have the tape on.

That picture perfectly shows the Tablet " POWERING UP with a DUMBBELL" getting in shape for 2024 ! It will boot up stronger than ever.
[TouchPad General] DoubleStuff:
LOL, that is funny "POWERING UP with a DUMBBELL".....but does not the picture show it powering down?

I was planning on powering it down, so if I was watching TV I might miss the "Moboot screen"

Lets get this straight so I am clear.....

PowerDown is Power/Vol-up ( closer to power button )/Home ( 3 finger goodbye )

Moboot Screen is Power/Vol-Down ( closer to home button )/Home ( 3 finger hello )

Giant USB symbol is Power/Vol-up ( closer to power button ) ( 2 finger salute )
[TouchPad General] DoubleStuff:
Good news everybody!!!

We are halfway home now, its my believe that the 15 lb DUMBELL knocked some sense into my hp touchpad, while I took a picture, and then after I read HP_TOUCHPADs advise to take it off, that must have been enough time to power it down.

Then when HP_TOUCHPAD told me press Power/Vol-DN/Home to power up. The battery symbol shows up! That actually is the first signs of life for this touchpad formerly known as "pale blue brick". I will now let it charge overnight, but I don't see the home button blinking so we will see where this goes. Will update in the next few days.
[TouchPad General] HP_TOUCHPAD:
That is Volume Down, not powering down !

Tablet orientation : Power key Left Top - Home Key Right ( Horizontal )

Volume Keys map : Key Closer to Power is Volume UP ( as in your picture with tape on )

Key pointing at Home is Volume Down

That is HARD RESET and will boot into the Moboot Screen

Correct, but if the home key is also press, it will set the Tablet to TOTAL OFF, and only doing a HARD RESET will turn it on.
[TouchPad General] HP_TOUCHPAD:
Congratulations ! Now we know of another trick, the DUMBELL workout 1 and 2 no reps but resistance !

Eventually the battery got low and rebooted, home will not do any light dance as the battery symbol is on the screen. The dance as some calls it, is when the battery is waking up from total discharge. Your tablet will boot up in less than 30 minutes.

But you got to be there to prevent going to Android, because it will give you the Pale Blue look again.

Is Tablet baby seating time!

Have FUN.....
