Hi,
i have a european htc flyer with LeeDroids actual custom rom (GB).
Today I drove my car, while charging it with a special 12V - Micro USB-Car Cable.
I tried google navigation and some other features and after that I chose HIBERNATE from the power-menu.
After half an hour I wanted to reactivate the device but everything I try - it simply wont start. display stays black, i tried every button (including the combination to bring it in the recovery mode). nothing works. the red light next to the power button is on (as if it is still loading).
has anyone an idea, what i can try to start the device, is it a brick? what about garantuee in this state? what should i do??
please help, thx
You need to give it time on the proper wall charger. Red indicates a completley depleted battery. I don't think you'll get what you need from a usb charging mode at this point. It could take some time to revive if you've push the battery far enough to deep discharge becasue the initial period will be used to recondition the battery at very low current.
...has been on the wall charger for hours - no effect
Can you plug it into the PC and see if it detects anything at all and if it does what is that. The other possibility is that you've somehow ended up in download mode.
I ended up in download mode on my original incredible. Not fun. See if it boots if you plug it into the pc. If so, I know how to fix it.
Sent from my HTC Flyer
nothing detected when plugged in via usb onto my pc
tried also adb shell, sais no connected device
think its really dead...
i have a flagship store in town, bring it in tomorrow -keep you posted, what the problem was/is
Let Lee know too if you haven't already just in case there is something in the code causing problems. That way he can pull it to keep other people safe.

Hello!
I purchased this device some time ago and did not modify it in anyway (no rooting/flashing etc), just a stock device. After leaving it just laying around for about a month I tried to turn it on again and nothing happened. Connecting it to USB or wall charger just makes the power button red led blink intermediately.
Ive tried:
Reset button
Hard reset (vol up+vol down+power button)
Leaving it to charge overnight from the wall charger
Leaving it to charge overnight from USB
Singing to it
Specifics:
Stock firmware
Viewsonic VPAD7
Model#: VS13761
Any help would be appreciated (even as mundane as saying "its hardware is fried") etc, just want some clarify on what happened if their is no way to fix it.
Thank you in advance
Same problem
Even My Vpad 7 is having the same problem.
Can anyone shed light to the above problem?

Let's start with here -

Can you hold the "Volumn" Down button while pressing the Power button to get into FTM mode (diagnostic screen) - make a note of the basic information it displayed.
To exit/reset - you might need to use a small pin to press the Reset button at the lower bottom (left) of the device to get it to reboot.
If it does not reboot, power down or shut-off, does it stay on with only the RED LED flashing.
Probably the battery is dead or dying..
i am in a similar situation.. i can only see a Red flashing LED. the tab wont reboot, go into diagnostics or respond to any plethora of button press combinations..
For those of you reporting problems with your Vpad7 - apparently not responding & only flashing red LED, can you access/read/verify your device's FTM status? Does it show any sort of boot-up sequence at all (the 3 birds being the common one for official Viewsonic Vpad 7's?
Please re-check your mSD card - you have one inserted right? properly formatted and not corrupted, readable as a USB drive when taken out & connected to a PC? Try removing any Sim card or vice versa, insert one and try to boot it up? Has the battery being charged to 100% (using the stock 2.0A charger - typically take 4 to 8 hours)?
Since it's NOT rooted and has no custom recovery installed (right !) - even a successful effort to boot into Recovery Mode won't help at all, but, it will help if you can get into bootloader mode.
Still following ... if everything checked out up to now, it's very likely that your ROM was corrupted/damaged and you need to reflash the "correct" factory ROM (RUU or *.nb0 file) using the factory utility - as discussed in the referenced link .
If you think you know what you are doing and dare to try a DIY rescue by flashing it all over (got nothing to lose anyway, it's a brick - paperweight at this point) - see if you can access the viewsonic website and download the files directly ... if you cannot download/access the files, please post here or PM for possible alternatives from my private collection now in cloud storage (it's geared mostly for newer/ITE devices, however, but not all of it) Please be specfic with your model's firmware/build & other info as shown under FTM or see your factory carton's box for the technical info.
If it's under warranty, by all means, contact support & get RMA to return it for repair/exchange - in 2 to 3 weeks (4 ?) you will have it back in working order, good as new - no fuzz, no worries & the "brick" can fly in android again.
If none of these apply, another possibility for the advanced users daring to play in a "what do I get to lose at this point situation" - to try to connect it to PC and run ADB using terminal emulator, to try to bring it back to life or at least restart/reboot it. http://forum.xda-developers.com/showthread.php?t=1229804
Good luck & I will check back soon ...
Unfortunately, mine will respond to none of these. nothing shows up on the computer when i plug it in.. not a sound, nothing. i may try booting up my old linux partition and see what /var/log/messages has to say when i plug it in..
i have an inkling that the battery has completely died though.. its a smart battery so has a PCB attached to it. if this has gone then i doubt the tab will power up.. unfortunately, replacement batterys arent easy to source..
i will let you know how i get on with it later on tonight when the GF and Kid have gone to sleep so i have some peace to potter around the house..
cheers for all your help my friend!
Today I plugged it in to my computer.
There was a white flash on the screen then same thing happened again.
The red light will blink sometimes or it will stay on as if it is charging but nothing is showing up on the screen.
Does anyone know how to open up the viewpad 7 or a manual on how to change the battery?

removing the back is rather simple.. run a credit card or any thin plastic along the edge starting at any corner.
good luck finding a replacement battery though.. i have searched high and low and cant find then for sale to the public that isn't a bulk order anywhere.
if you do find somewhere, please let me know..
Mine is an olivepad but I think the viewpad 7 and olivepad are the same hardware wise. (I may be wrong).
Maybe we can exchange the battery with another with the same voltage rating. And maybe higher mAh rating for better battery life?
It's already bricked so I don't mind experimenting a bit.
Here are some pictures I snapped.
vpad7 wont turn on

Open vpad7. Remove the only screw top near sim/micro sd. Remove Batt. connector for 15-30 seconds, put it back turn on and charge fully. (Its bcoz of fully discharged batt.)
Thanks

Viewpad 7 won't charge battery and power on
Hi
Seems like it might be enough to just parallel connect a phone battery, with 3,7v to the battery PCB for a short period, to be able to charge the battery again.
Mogens
I disconnected the battery for 30s and assembled it back again, but the red flashing continues and it can't be turned on or charged.
Battery is over discharged.
1 - Open it and disconnect battery connector on mother board and reconnect and try to charge. If the battery percentage appears on screen appears and moving means its charging. Charge for few hours then turn on.
2 - Disconnect battery connector and charge it for 5 mins by using any 5V 1A power source for any mobile. Then put back battery connector and charge using original charger. If no other 5v 1 A source available, you have to cut the wire of same original charger and use +ve and -ve.

Hi guys,
I'm repasting what I wrote in my previous thread hoping you can have a clearer view of my issue.
My phone has the standard ROM, WP 6.5, nothing changed
I never flushed the phone, never formatted it, etc, everything is legit!
My TG01 has died many months ago and now I'm looking into ways of having it re-activated. I will explain to you my possible theories why it died, so maybe some of you will have an idea how to fix it
- For the first 4-5 months I only used PC USB (synchronization) charging, as I had a UK mains which obviously does not work in Europe. I noticed that the battery indicator was never really accurate, showing me the battery levels very vaguely.
- I often synchronized my Outlook e-mails with my mobile phone, one day my phone died when I chose to synchronize all e-mails. It died to an extent that the battery was completely empty. My PC wouldn't recognize it and it would only start for 5 seconds (the red led lamp would shine) and then die...
I somehow managed to revive it with my normal charger but afterwards it used to overheat quite a lot...
- One day I left it to synchronize again and the battery died on me again (at least that's what I think had happened)... the difference that USB PC charging did not work anymore as well mains charging. I was desperate enough to buy a replacement battery from eBay and I still have the same story. When I connect the phone to the charger I don't even see the diode lighting up anymore.. NOTHING. Any tips?
Could it be that the replacement battery is also so empty that even a mains can't charge it anymore? I heard someone mention something with cutting a wire etc, ... would that help me? IF so.. how do you exactly do that?
Thanks!
Hi guys,
So far no luck in getting updates from you, but I've got an update for myself:
I somehow managed to get the LED diode turn red when I connected it to the computer, which should be indicating the fact that the phone is charging, right? When I try to power it up the device manager recognizes a device called TOSHIBA DL... does this mean my phone is in some sort of emergency state?
The screen lights up a bit as well, but remains black.
yess this means your tg01 is NOT bricked. try take your battery out and put it back in so its totaly switched off then press n hold CAMERA, VOL UP, POWER keys to perform a master reset. if that doesnt work try this,
use the short pin method, put a .tsw in a PRG folder at the root off your sd card and short pins 1 and 3
if not,
download a tg01 rom in a .bin and flashh the .bin via tgdownloader
if you dont know these methods please tell me and i will link and help you.
Hi!
Thanks for your reply. If you could guide me a bit with the pins method, that would be great.
Also, when I plug in the mobile phone to charge now the red light is now flashing, instead of remaining constant, what could that indicate?
Phone never turns on now
hi there, it sounds like your battery has gone flat try leaving it on charge via USB for a few hours see if that will kickstart it and for the pin method
http://forum.xda-developers.com/showthread.php?t=654674
try to charge your battery first as it may just be a flat battery but if not you may need to reflash your rom via the pin method
if there are any problems or you are unsure message me back
Please help! My dear friend asked me to fix her broken 610 from what I couldn't even restore to the original ROM. I've tried to download some roms that were as close as to the device that I have (a Polish PLAY.pl 610) but unfortunately couldn't load it through fastboot, adb or recovery. But that's not the subject right now.
All was ok (I could boot it up to fastboot), but one night I sat it down, and the next day it was dead.
- The orange diode doesn't light up when plugged to PC/socket charging
- Power, Power+VolUp, Power+VolDown, none of the combination work, the screen doesnt even flicker
ALL that shows that it is there, is a QHSUSB_BULK unknown device in Windows Device Manager...
Is there a way to fix it? I didn't manage to flash the ROM I just rooted it with HTCs tools, the next day it was like this.
Thanks!

Sounds like a dead flat battery. Take it to a phone repairer and get them to give the battery a boost charge . You can do this your self if you know what your doing but these battery's can explode if you don't know what you doing and you'll need the right equipment, so if YOU DECIDE to try this be very careful (I am not responsible for any damage that may occur if YOU DECIDE to attempt these repairs yourself).
- remove the phones back cover
- disconnect the battery
- connect the battery (with correct polarity) to a bench top power supply with the voltage set to 3.5 volts DC and current limit set to 150 mA (this is very important, incorrect polarity or power supply settings may result in flames or explosions) and monitor the battery voltage. Once it is above 3 volts you are done.(if the battery seems to be getting hot at all during this process stop immediately)
- reconnect the battery and and give it a full charge as per normal in the phone.
Hi,
long story short: I connected my Z5C to a bad (apparently, I don't want to test ) charger and now I have some strange issues. Is there any change that my h/w isn't fried?
Full story: As I said I connected my Z5C (newest CyanogenMod provided here) to a charger and it instantly did a hard reset. Afterwards it did turn on and continued to work for some time. As I was on the road at that time I could not charge it elsewhere and later that day it ran out of power. When I tried to charge it with a known good charger some days later, it did not boot. I suspect the boot process to healthd or whatever draws this cool animation takes more power than my working but small charger provided.
It did charge at my laptop, especially when I put it into fastboot mode.
Now thats where I am stuck; the phone won't turn off completely and keeps rebooting when I turn it off (via os menu or hard reset, no chance).
I can charge it after it runs out of power (managed to charge to 100%), but it won't charge if I unplug and replug it. It is not recognised by a pc after I reconnect it one or two times (checked with device manager and lsusb), only chance to get to fastboot or flash mode again is drain the battery to 0%. It does show a loading animation and I can boot into android from there. Battery drain in Android seems to be a little higher than usual (100 to 0 after 2 1/2 days of pure standby without any radio stuff on).
I have already reflashed the original Sony firmware and erased everything that came to my mind (cache, data....).
Any hope that I did not kill some piece of hardware?
Thanks for your answers, any help appreciated
tell me more about your z5c's software, why you mentioned Cynogenmod? did you flash it with cynogenmod?
seems to me that z5c was running on custom rom and did not support fast chargers and bricked your device!
if that so, try flashing it using flashtool with original stockrom.
i don't wana go in to details however there is possiblity that battery.sys file is corrupt and atleast I was never able to fix my LT18i when it got bricked and battery status use to become zero in 2 seconds and android keep rebooting, later it got silent for good! no charge no nothing and i still have the device sitting. I was running it on coconut (cynogenmod) when all this happened!
Thanks for your reply.
The charger was no kind fast charger, just a common 12V to USB adapter with an output of 800mA (when it worked). I was running CM 13 when I connected it to the bad charger, but as I mentioned I have since then reflashed it with Stock ROM. No real improvement.
I have continued trying and I found out that the device seems to believe it is still connected via usb.
Code:
cat /sys/class/power_supply/usb/present
gives me "1" with nothing connected, can you check if this is normal?
The file is -rw-r-- r--, would changing its value change anything or is it just some kernel thing (can't check, don't have root permissions now as I flashed Stock ROM)?
Also after I charged it on my PC today it still shows me the notifications for USB connection and adb (I can add a screenshot if necessary), also looks like it still believes to be connected.
It seems I found the solution: I was playing a bit with a USB-OTG adapter (the ones to connect regular usb devices like keyboards or storage to your phone). After I connected a USB keyboard I tried (just for fun) if the Linux "Magic" SysRq hotkeys were enabled. So I did press Alt-Print-o, which is the Linux hotkey for "turn off now". It did not turn off, it also stayed off (no instant reboot). After I started the phone again it also properly turned off via the power menu!
I will have to test whether the charging issues are fixed, too, but as far as I can tell the problem seemed to be something software-related
Sadly did not work for long. I think I will go for official repair, think this is still cheaper than buying a new phone (after completely killing it with some DIY "repair" attempt). This annoying brick simply does not turn off, no matter what I do (apart from draining battery to 0%). Guess its my fault, still to afraid to try that broken charger again.
I recently picked up this galaxy s6 edge from a friend that upgraded to a new phone. It won't turn on, neither to android recovery, nor to download mode nor the android. I charged it via wireless charging overnight and i tried for around an hour with a usb cable. What do i do?
same issue i am facing, i tried original charger, wireless charger and fast chargers from many different brands. but all failed. The device only gets warm/hot while charging and nothing happens. neither download mode nor recovery mode works. I am kind pf stuck without any solution, my device was used very rarely and its like an brand new device. Doesn't know what to do, if you find any solution then please let me know too. thanks in advance
Same problem. If I press power button very long, blue light comes on. Then it's stuck and stays like this until battery is flat. Battery charging is not possible: device heats up (tried USB and Qi), but battery doesn't take any charge.
So I opened the S6 and checked the battery directly. I can charge it directly with a lab power supply and when I plug it in and press power button, the blue notification light comes on again until battery is empty again. I can also see that only ICs get hot, but not the battery when plugging in USB.
So, it's definitely some hardware fault. I suspect power IC that is not able to power up the screen. But I don't know. I will investigate further but it looks difficult. However, I have seen many YouTube videos with same symptoms, but problem was always different than mine :/
Hi guys,
This thread is 2 months old, any of you managed to fix the problem?
I am having very similar problem. My phone was on a shelf for about a year and a half. Before now it was working perfectly. Now I can't charge it via USB or power adapter. When trying to power it up or get into download or recovery mode, nothing happens. Computer does not see it. Tried different cables, USB ports, power adapters..nothing.
The only thing that is happening to the phone is the battery logo appears when trying to charge it, though the green bar does not go over battery, only the empty grey battery with lightning icon in the middle. Also the screen does not go dark after a few seconds as it should and the red/blue LED does not turn on.
Is this the signal from the phone, that the battery is to deeply dischareged and cannot be charged again? I am googling all over the web and can't find anybody talking about what phone does in case of to low voltage on battery.
PS back does not seem to be bloated, USB port was working perfectly last time used
Please try to help, you are my last stop before opening the phone and start probing the poop out of motherboard to see what gave.
EDIT: something interesting happened just about an hour after my post. The battery suddenly started showing % of charge and the green bar started running, computer recognized the phone.. as everything should be.
My FIX: leave the phone pluged in and charging for about 3days and it will start working again.
My semi professional explenation of fix and problem: the phone has a ''backup or reserve'' battery. It is actually main battery but the last I think I read somewhere it is 20% of capacity, is reserved for phone exclusively for the clock and all other electronics that need power when switched off. Now these 20% probably were discharged due to laying around for almost 2 years.
It took me 3 days of charging to fill up these ''20%'' I guess. Probably because Lithium batteries are charged VERY slow at very start and end. This is safty procedure for ALL Li batteries.
If any expert can confirm my conclusion please do so, to help other people.
To answer partialy to my question: The phone tells you battery is ''deep'' discharged when you only see the charge icon without the green bar.
In the mean time I was writing this edit I came up to 4% battery and turned it on!
