Hi guys,
My S III seems to be working fine once the battery is charged. I have been using another S III to charge my battery (which is very annoying).
I thought it might be the USB port and am thinking of replacing it. However, there are also other symptoms which I have not been able to discover anywhere else on the internet yet.
First, when pressing the power button on the side, the phone does not boot like it used to, i need to hold the button for longer than usual and then the charging icon appears, before booting to the home screen.
Second, the battery icon in the top right corner always has an exclamation mark in it like it is critical, but the battery will last as normal.
So, all these three things are connected to the battery and charging, but how? Does anyone have any suggestions how to fix? Remember, I can not use the USB port so the phone does not connect to my PC. Thanks!
Hi,
This thread is being moved to your own dedicated forum, where the experts may be able to help you better.
Good luck!

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 -
http://forum.xda-developers.com/showthread.php?t=1015005 - post #6
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.

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.

Hey guys and gals
this is my first post here. although a lot here is about rooted devices with custom ROMs, I hope you can help me out - you sure have a lot of expertise here compared to many other forums.
For the past two days I've been running into some of the weirdest problems with my Galaxy S2. Before i go into detail, here is the summary:
1. Screen time-out doesn't work while device is not plugged to a charger or computer
2. Notification shows 100% charge for a very long time (hours after heavy usage)
3. Not sure if charging actually works
4. Booting up seems to fail when not connected to a charger
it started yesterday when I noticed the phone light up and say it was charging. The problem is it wasn't - it was in my pocket.
Then I noticed that the screen didn't time out. I changed the setting, nothing - it remained on. I could push the power to make the screen turn off and on again but it wouldn't time out itself.
The charging info went away... at some point. I left it to charge over night and in the morning it indeed showed 100% in the notification bar. The problem is it remained 100% for A LONG time. In the settings menu under the battery it says it has been running on batter for 0 secs and showed 100% charge. For hours... There were no info about any apps or function using the battery. that part was clear.
Then i discovered that the screen time out problem goes away while connecting the charger or via USB to a PC. Then it times out. As soon as i unplug the charger it never times out....
I'm actually not sure if the charging works. Indeed it shows charging but sometimes it magically reaches 100% rather quickly.
Because I suspected a battery fault I used another battery. let it drain completely and then tried to recharge. Can't - when booting it shows a battery icon with question mark and then goes to show that the battery is 100% charged. Then the question mark and then 100% again. Seems to be in some sort of loop.
I've done the factory reset, I had a new firmware installed via Odin just in case. The problem still remains.
Booting the device seems to be an issue and only work with charger or USB cable attached. Ot it will be in that "what battery" and "100% charge" cycle...
I've searched high and low today but couldn't find anyone with the same problem.
Have any of you an idea? Really down't want to get a new phone! Seems to be a very bad month going on because a few weeks ago I had really serious issues with my brand new hybrid camera which i have to buy ... again! sold it for parts for pocket money....
Any help would be really appreciated! thanks!
That's really strange....try getting out the battery,charge it to max va an external charger,or borrow a friend's Galaxy S2.Leave the phone withou battery for an hour.Then when you put it in,go to recovery,and "wipe battery stats"(Root it if it's not).See if that works.

How long have you had the phone? The usb flex cable has issues over time. A symptom of this is the charging when not connected to the charger.
If it is this issue the part is cheap (around 5$ I believe).
Found several charge problems, but no solution/explaination for this case:
My S2 works fine if connected to USB (but only with battery in phone). Nevertheless, it shows charging, but it just sticks at 0%.
I assume, the battery is ok, because I can boot an S3neo with it. Second is, although it shows 0%, it can do something like a shut down, while disconnecting from USB (so it goes off, but shows this logo first).
My assupmtion is, that for some reason it can not reconize the status of battery and think it is empty. That's why it goes off immediatly after disconnecting USB from charger or PC. Data transfer is working, so cable is fine.
Any idea what might be wrong and how to repair? I don't have another battery available, but after using my one in a S3 (other way around it doesn't fit) - I don't want to spend money for a battery, if this is likely not the reason.
Thanks!

Hey mate,
If your phone goes off immediately, then I guess it means that your phone's battery has died. Since you don't want to change your battery, you can try a custom ROM - Maybe SlimSaber 4.4.4, Neat ROM, CM or Slim and check whether the same thing is happening or not.
If the problem still persists, then it can surely be fixed by purchasing a new battery.
This is a sort of workaround to verify if your battery is faulty or your ROM.
All the best!
Regards.
It's not going off immediatly. I mean, not as would remove battery (if device would work with just battery). You see logo for short time. It's an original sofware, I did a reset and I can't believe this is a ROM problem.
And... this battery works on an S3neo (as the accu has same contacts and is smaller I can connect it to this device, but not other way around).
I would like to know, how charge status is calculated by the mobile. Can I by myself measure this? (Inner resistance, current ...)

There is an app that tells you the current which maybe of some help think it is just call battery current by memory.
My Galaxy S2 appeared to be working fine with no issues but during a charge one day, I noticed it had gone black and wouldn't turn on. I swapped out the battery and changed the charger (both taken from a different S2 that had no issues) and it didnt fix the issue.
The rundown:
Taking a different battery/charger that works with another S2 doesn't make any difference
Phone doesn't show the battery charger icon when plugged in
My PC doesn't recognise the phone when I plug it in via USB
The USB jig doesn't seem to help do anything
Tried removing the battery and keeping it out of the phone overnight, put it back in and still nothing
Tried removing the battery, plugging in the charger, waiting awhile, putting the battery back and straight away pressing power button - nothing
The only sign of life is that the phone gets warm around the camera area when left on charge.
Any ideas?

my phone doing the same Since like 6 hrs ago
did you tried to turn it on when you didn't has battery (low battary) ? or you got the recovery mode before your phone stopped turning on ? because mine did and i dont know what to do too
I think you have burned the logic board

If this is still relevant (the OP posted 2 months ago)......
Phone won't power on, no charging icon when charger plugged in, recovery and download modes inaccessible, usb jig doesn't help, phone getting warm by the camera......I remember my time on the S2 forum, and these are all (when combined) a classic sign of a HARD BRICK.......
HARD brick = HARDware brick
SOFT brick = SOFTware brick
SOFT brick......usually recoverable
HARD brick......start using your phone as a paperweight......
Sorry mate, but unless you're prepared to spend out on a new motherboard, you ain't fixing it.....

Thanks Keith & all.. it was indeed a goner. An expert took a look at it and found that the cause of the issue was the EMMC chip where the data is stored. Unfortunately it is too tedious/complicated to replace due to how it is soldered to the board (requires specialised equipment etc) so it was a choice of replacing the entire board or bust. Just wasn't worth it for an older phone. I ended up buying a Xiaomi Mi4i to replace the S2 and have been pretty happy with it (save for a few software bugs now and then).

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!
