[Q] No Recovery, Black Screen - TouchPad General

Hi,
i bought a Touchpad on Ebay. The problem is that i can't get it into Recovery or anything else. The screen went all black. I tried several key combinations (volume up + power, home + volume up + power). When i plug it to my pc it recognizes a device. I also tried the WebOS Doctor but no success. Is there a other possibility to bring it back to live?
Greetings Markus

You say it's recognized, so that's a start. Try this:
Press and hold VolUp + Power, then repeatedly hit Home about 15-20 times. You won't notice anything happening, but that forces it to do a hard poweroff. Then, press-and-hold Power + VolUp + Home, and that should turn it on in WebOS Recovery Mode.

Actually, you dont have to do all these weird button combinations to get into recovery. just holding down the home button and the power button for about 10 seconds forces a reboot. When it restarts, but before the HP logo appears, just hold down the volume up button to go into webOS recovery. You will know you are in recovery when you get a big usb symbol in the middle of the screen. If you ran the webOS doctor, you would have had to do this so when you say you ran the doctor, did it actually run it?

Hi,
thank you for your answers. I have tried these combinations several times, but with no success. But I can hear, when the device is connected to my PC (Windows), that peep peep sound when you plug in an USB device. So there will be a reset of the device i think.

Maybe the screen is dead. If your Touchpad is off, I dont think the computer will recognize it until its turned on. If your computer is recognizing it, I would think that it is on, just not displaying anything. When you press the volume buttons, do you hear any sound indicating the volume is being adjusted?
When you bought it off of ebay did you make sure it didnt say broken or for parts only, something like that? How much did you buy it for?

Deleted partition? Thats probably not good. So did the seller actually describe that it wasnt turning on and working? If, somehow, they deleted the whole operating system off of the tablet, including recovery, you might be in a bad place with that. There MAY be a way to force load webOS on the device but I, personally, don't know about that. Someone with more computer skills will have to help you. If the seller didnt explain that it wasnt even turning on, You should try to contact them.

Hi, he did mention that.
But i thought the recovery mode still works. So my fault.

Ah. Well I dont know if there is a way to get it to work. If anyone can help you though, it would be the people over at webOS Nation. Maybe try asking over there. webOS devices are their thing.

Thank you for your help!

[Q] Bootloader/Download mode blocked on new/replacement Vibrants?

Hello community!
I own 2 Vibrants, both rooted with no issues. I'm no stranger to flashing through Odin, I've flashed many of the Vibrants in my workplace back to the stock 2.1 (seems to fix most of the issues short of GPS problems, even though it's supposed to be the same), so download mode is nothing new to me.
Recently a few of the people who've come to me with Vibrants have shown how they can't get in to recovery or download mode without using ADB, the hardware keys just don't seem to work for it. I've tried myself and was able to confirm this. We were still able to root them with no issues using one click root. I prefer to manually flash the update.zip myself, but whatever does the job. I've just received a replacement for one of the Vibrants (menu button went out), and noticed I can not get in to recovery/download mode. Naturally I rooted, installed terminal, then rebooted in to download mode, started a flash with Odin.
It hung on cache.rfs. I waited... and waited.. and it mocked me in it's frozen status. So now I'm at the phone+!+computer screen, which I've been at several times on my main Vibrant, but the key's still do not work for download mode. To clarify, I've tried each of the following methods to enter in to download mode, several times. It won't work. I'm in the process of trying different button combination's to see if there is another way to get in. Anyone have any thoughts or suggestions?
Edit: Included working steps so people don't have to search the thread
Provided by rhcp0112345:
Try this.
1. Take out battery, put it back in. (to turn the phone fully off)
2. Don't turn it the phone on!
3. Plug the phone into your PC, do not hit the power button!
4. See if the phone shows anything on the screen (powers on its own when plugged in)
IF the phone screen does 'turn on' after being plugged in without you hitting the power button, so far so good.
5. Now while it's on like this, hold the volume up AND volume down buttons.
6. Hold the power button as well as the volume buttons until the screen goes black.
7. As soon as the screen goes black, let go of the power button! But DON'T let go of the volume buttons!

Hello,
If the above does not work for you.
Can you supply a full dump of the phone? Perhaps I/others can take a look at it.
Thanks!
I have tried that. I have tried almost every combination I can think of. I have tried holding both volume rockers then inserting the battery while plugged in to USB, holding the power through 1 and 2 cycles, I have even tried 3 and 4 cycles as well. I have tried just vol down, just vol up, both with the same results. I have purposefully bricked my main Vibrant to test this out and make sure I wasn't losing my mind. I was able to get in to download mode several ways, none of which work on this new device.
@rhcp0112345 - How do I grab a full dump of the phone? I'll be honest, I've never spent very long in phone+!+computer before tonight. I've never been stuck here long enough to see how to connect via computer. At this moment, plugging the phone into the pc gives me no prompts that something has been plugged in, the phone isn't seen by adb (big shock) or Odin. I'm at a loss myself.
Well,
First thing.
Can you please dump like so:
Code:
adb shell
su
busybox ls -al /dev/block/
Post that here.
Also,
Code:
adb shell
su
dd if="/dev/block/bml0!c" of=/sdcard/bml0.backup
Please 7zip the bml0.backup file and upload it someplace and PM me the info. Dont post it public.
Thanks!
I'll be happy to do that with the next device I have this issue with, but I can't boot the phone, therefore I can't connect via ADB (been trying, if I could do adb, I could just simply 'adb reboot download' to get in to download mode). I'm thinking at this point I will have to exchange the phone, as I can't get past the phone+!+computer screen no matter what I try.
I was running into this problem too. I re-extracted the files and tried again and it worked. I also tried it without loading the .pit into odin, not sure which of two or both did it. Not sure if its the right way, but that did it after hangin on the cache numerous times.

Follow the unbrick method.
You pull the battery and some other stuff.
To get it past that.
I think its volume up? + power?
Yeah, removing the .pit file seems to fix the lock up issue in Odin, but unfortunately, I'm not even getting to the download screen, so I can't get Odin to find the phone. I'm sure once I get to download mode I can get it running, but I'm unable to get download mode on this one device.
Try this.
1. Take out battery, put it back in. (to turn the phone fully off)
2. Don't turn it the phone on!
3. Plug the phone into your PC, do not hit the power button!

If you mean this solution to fix any brick, I have tried that method, it doesn't work on this new device. I originally used this thread when I was messing with my first Vibrant, and it worked beautifully, but it doesn't work on the new vibrant.
So I've pretty much given up on trying to figure this out. I've tried every method possible, all work on both my non-replacement vibrants, but nothing works on the replacement one. Going to have it replaced again and have a new one ordered out. When that one gets here, I will test download/recovery modes, if I have any issues, I'll pull the dump file and post it here, maybe someone can figure out what's going on. On the back of the device, the IMEI sticker has manufacture dates (year.month), looks like the replacement was a 10.7 just like my original Vibrant, so it's not a manufacturer date type issue, it's got to be something changed in the software side of things. It's almost as though the volume rocker keys do not work for recovery/download mode, I get the exact same thing as if I'm just pressing the power button. When I did get in to recovery (before getting to it's current state), the volume keys worked fine for selection though. I can confirm that there is no new information on tmob's side about how to do a hard reset using the hardware buttons (ie, recovery mode) as of this posting.
Did you try with the phone OFF..
1. Have ODIN running
2. Hold Volume Down + Up
3. Plug in USB (WHILE HOLDING VOLUMES buttons in)
Should go directly into DOWNLOAD mode
I did try that as well. Works beautifully on both my old Vibrants, but not on this new one.

@ Johnny12times: Dude u'r right. I've played around with a few different vibrants and they could all go into "download mode" - but when receiving a replacement unit (within the last 2 days), nothing works to go into download mode. Something has definitely changed - not sure what.
Good luck bro - hope it all works out.
I received my Vibrant last Thursday (8/19). I have never been able to boot into recovery mode using the buttons. Needed to root by using one-click.
Ive also tried every button combo and am still unable to get recovery or download. I received the phone last fri (8/20). Its so frustrating knowing that so many other people can get manual recovery. Im sending it back tomorrow for replacement, but who knows if that one will even work? I hope someone figures out why so many vibrants are unable to do this. Good luck!
Well my new one should be here within the next day or so, as soon as it arrives I'll check it and pull a dump file. I'm not savvy enough to figure out how to fix it, but at least smart enough to put it here for the people that can.
How about this:
1. Remove SD and SIM card
2. Remove battery
3. plug the phone into USB
4. hold down vol-up and vol-down
5. pop the battery back in while holding vol buttons

Tablet won't power on anymore.

I was using my tablet while finishing charging. I was about 95%. Suddenly it just went black and won't turn back on. Any ideas? I've tried holding the power button with no results. Is there a special reset or something?
Anyone else have this issue or things I can try to fix it?

Have you tried PC Companion? Download it for Windows then try to locate for emergency repair. It will show you instructions of how to put your tablet in flash mode.

I haven't tried that specifically, but would it not fail if the light didn't even go on when plugged in, and my pc doesn't even read it as connected?

Not really, for example in some samsung devices even if the device wont turn on the a JIG plug was able to put the phone on download mode, something very similar to flash mode on the xperia mobiles.
So i guess the last thing you can try is to put the tablet in flash mode, you can download a FTF file with the firmware compatible with your device, and download flashtool from: Click here to download and then put your tablet on flash mode. I guess you will need first the drivers Click here to see drivers and after you install the drivers, just open flash tool press the vol down key and connect the usb cable to the tablet, and if you see that flashtool or maybe windows recognizes your tablet you may have luck to restore it.
So if you get it into flash mode, then just flash the FTF and let's see what happens.
Let me know.
I will give it a test this evening or tomorrow - thanks! I will post back if it works.
PC Companion doesn't detect the tablet, nor does my PC at all in device manager. It doesn't respond like anything is plugged in, but it did before.
Flashtool comes up with nothing either - once again doesn't even acknowledge anything is plugged in.
Thanks for the suggestions, though.

just happened to me not five minutes ago.

I read your issue. Read my first post again - yours is simply a crash. Mine does not charge, has no power LED, and is completely unresponsive. No recovery button combination or anything works - yours turns on and responds to things.
so when you try vol up and power button do you not see the white led flash once then a couple seconds later three times? if it does it means your tablet can still be put into flash mode with some perseverance.
Edit: you could try sony mobiles flash tool called Emma which has its own way of entering flash mode (think you hold vol down and plug the usb cable in the computer) and see if that program can detect your tablet but you can use the instructions provided on their website if your unsure what to do.
same sitation
I have the same problem with my tablet. I watched stock photos in album and then display switched off. And that's the end.
Nothing happens when I try to power on, reboot or restore with Companion. Computer doesn' detect device. The same situation with Emma and flashtool.
I used my new-bought tablet only for 15 minutes)))
Mine ended up needing replacing due to a fried mainboard. Did you leave yours plugged in overnight?
Ok something strange happen to the tab I never had problem before I left the headphone plugged in a press the power button to close the screen (I always do that) when I try to use the tab there was nothing on screen double tab the screen nothing, hold the power button nothing put the tab in the cradle nothing the led was not turning on but the usb cable direct to the pc and than the charger nothing. I press the volume up and power button the tab led blink and was able to restart the tab. ??????????
Same thing just happened to me. Power button would not turn on the Z. LED would not turn on when charged. Did a hard reset and it came back on. Model: SGP312.

Pc companion will not work in thta situation cause it needs the device to be powered on...
In that case have you try the SUS http:/sonymobile.com/gb/tools/update-service/
Just follow the instructions and you will be fine
It will erase the entire internal memory though, sd is fine..

Dead Moto E

Folks,
I tried to restore my moto e to 4.4, after being automatically upgraded to Lollipop.
It worked perfectly fine. I was able to downgrade.
But somehow, one of my friend has again updated to lollipop once again, OTA (on the air).
From that moment, the phone never boots. Press/Long press on power button results no where.
After connecting it to laptop or power source (Charger), Press/Long press on power button results in blinking of the notification light (white).
Blinks and nothing happens.
Device manager shows "RELINK HS-USB QDLoader 9008".
Let me know ow to trouble shoot from here.
:good:
Hi,
what's happening, when, from power off state, you press the power and volume down buttons simultaneously for 10 seconds and release them?
the phone is dead, there is nothing you can do to fix that. sorry
Not working.

yup.. Tried switching on. Not working.
Tried to load into recovery mode, no luck.
The only symptom is, connect the phone to laptop. Then hold volume down and power button, Nothing will come. But only the notification light blinks.

OOPS.
So, No blank flash files for moto e?
I also faced the exact same issue and my MOTO E XT1022 is dead now.
@kingvijay023 any luck till now?
I too had the same issue on my XT1022, i connected it to a "charge only usb cable" for 1 full day and then I was able to reboot to recovery (twrp) using adb.
Then I flashed lineage OS 8.1 and now everything is fine.
When I was using a data transfer cable to charge, it just blinked the notification light and didn't respond
Open the device up and remove the battery. Either replace it or find some way to charge it outside of the phone.

Shutdown goes to factory download mode

I tried cleaning my usb port and in the process i apparently broke it cause it wont charge. Thing that is confusing me is when i try to shutdown the device it reboots to the download screen and on top says factory mode. Only way i can seem to get out of it is to hold vol down, home and power and then cancel click volume down to cancel. Im really hoping these two issues are related but has anyone had similar problems?

Help, blank screen and unable to boot

I was searching for a solution for my contact sync issue and I needed to reboot. After pressing reboot, the screen goes blank and I cannot boot again. Volume up + power doesn't work. Plug in power and the light didn't turn on. Even try to hit the tiny hole that looks like reset and that didn't work with. Help!
I am on official miui 9 with Google installer
Did you hold the power button for a longer time?
Yes, try holding the power button for some time. One time, after fastboot, it took around 90 seconds to power up.
there's a tiny hole that looks like a reset ????
did you poke the mic hole?

Hi Rioru, did you ever find a solution to your issue. After charging last night, suddenly I had exactly the same error. Which means I cannot boot the tablet, Power+Volume UP does not respond, charging LED not responding and after connecting to a PC I cannot not establish an ADB connection.
Thanks!
