Hi all,
Recently my brand-new Be Touch was suddenly bricked, I don't know why but it was unresponsive to everything... they screen just didn't wanted to show anything even when I connected the charger or plugged it to my laptop.
I tried all the instructions I found (there are really a lot of just googling "recover bricked phone"), even the official instructions to flash a new ROM (http://ulefone.com/download/betouch.html) But again nothing... screen completely black.
I tested the battery with a multimeter and it appeared to be full charge.
Finally when I had already contacted the seller for a return, I found a very old post (2013) about recovering a bricked device using Ubuntu (I'm using Linux Mint).
So I had SP Flashing Tool open (not doing anything special because it didn't detect my phone any longer) and in the Options -> Connections -> "with battery" marked.

The USB cable was plugged and the battery on its place.
I pressed "Power + Home" buttons simultaneously for around 30 seconds. It's real, I had tried before for around 10 seconds and nothing happened... and arriving to the 30th second suddently the screen brighted once, showing for an instant a 0% battery and went down again... Hope was back
I left the cable plugged for some minutes before touching anything. When I pressed again (5min) the percentage was still at 0% but the screen response was faster. So I decided to boot the phone and it started
It was connected and still showing 0% battery. It started as on the 1st boot, asking me for everything, but everything working. I wait for around 10 minutes and... the battery was still showing 0% :-/ I decided to turn it down for a faster charge.
I left it around 45 minutes shut down to reach the 15% of battery (fast charge they said!) after that it started charging a little bit faster, I waited until 100% before turning it on.
Once at 100% it booted well, restored my config and everything seems to work well again.
Today I have installed a battery repair app (called Repair Battery Life free on PlayStore), and it has detected around 10 deffective units on the battery :-/ (someone in red) but after clicking on "Fix it" and wait for some minutes it everything appears OK now. So I will pay more attention to it working and the battery from now on.
I don't know if all that story was caused by the battery... but at least my Be Touch is back
I'm trynig to paste screenshots of battery recovery, but I can't :-/
PS: if you find this info useful, I would appreciate if you click on "Thanks"
Maybe this post should be on "Help & Troubleshooting" ?
Not sure...

So my TF101 appears to be completely dead. I had it rooted and rom'd running KatKiss 4.3,not sure of which number . I loved it too. Anyway, before it died, it rebooted and would not leave the "updating apps"screen so I did a factory install which fixed the problem but only temporarily. A few days later the same thing happened. This time I could not even reboot it. I left it charged overnight but could not get it to boot at all. I think I have tried everything. I tried booting with and without being on the keyboard dock, I have tried plugging into the computer, tried hdmi to a monitor to see if the screen went bad. I tried seeing if the computer recognized it in APX mode. NOTHING. The USB charges the keyboard dock but does nothing for the tablet. The computer does not see it period. It looks completely dead. It is out of warranty but I even called ASUS and all they would do is charge me $340 to send it in.
I would love to troubleshoot to see if it is a board or battery or whatever gone bad , but I cannot find anything on the Web. Can anyone help. Otherwise it's a lovely paperweight.
It's possible that the battery has come to the end of it's life and won't hold any charge, which would explain why APX mode won't work, the PC can't power on the TF via USB, only trickle charge it while it's powered off / screen is off, but if the battery is dead then that's not gonna happen either
Not sure if the charger needs the battery for it to power on the TF too or not
You could try disconnecting the battery and plugging in the charger
Here is a good teardown video to show exactly how to get that done

Im not 100% sure, but if the dock battery is fine, you could check and see if the connections are the same and swap them over

Still DEAD
Detection,
Thanks for the awesome YouTube of breaking down the TF101. Unfortunately, I swapped batteries and still no good. Nothing happens. It looks like the old battery has power too, based on my multimeter. Is there anyone else with suggestions at this point or do I leave it as a nice paperweight?
THansk....
Apologies for resurrecting this thread. My TF101 (with dock) had also gone dead after running one of the KatKiss ROMs (maybe 4.2). Wouldn't charge, wouldn't turn on even to the bootloader or recovery. Charged it for days, nothing. I left it for dead and forgot about it for over 6 months. Uncovered it the other, dusted it off, charged it and it magically powered up. Everything was still on the tablet as it was before it went unresponsive.
My guess is that a microcontroller responsible for powering up the tablet got into a bad state. Even when powered off, these very low power microcontrollers remain on to handle the button press that powers on the device. It took the tablet being absolutely, fully discharged to clear it out of that bad state. Not just 0% as reported by the battery firmware, but a true complete emptying of the battery where its voltage drops below what the microcontroller needs to remain running.
Hopefully if you still have the TF101 after all this time, try charging it up all the way and see if it comes back to life.
Hi all...
I think my N5 is buggered.
I was at a festival this weekend and my phone battery ran out so I left it in my bag for more of the weekend. On the drive back it was working fine as I was using GPs, making calls, using Gplay without any problems. As my GF wanted to charge her phone mine ran out again by the time I got home and I went to charge it as it was down to 2% but when I plugged the charger in it would not charge. It would start charging for a second then stop for a second and then start again. So I unplugged it and went to give it a re-boot and the screen came back on corrupted like this -

I have holding the volume down and power button to get to the fast boot menu and the screen does the same thing but this time while i'm holding it the screen with turn on and off wile vibrating 5-6 times before turning off.
I have even tried using fastboot to flash the recovery image onto the phone and it says everything has worked but again I get the corrupeted screen when I reboot.
Anyone seen or know of this problem? Or is it what I expect and it's got a hardware issue and needs to get repaired?
Thanks in advanced for any help or suggestions.

It's a problem with the flex cable, the screen, or possibly the motherboard.
A few people have had this issue.

Lethargy,
I had a feeling it was going to be a hardware issue. Thank you so much for the help... I'll get it sorted under my insurance then and get myself a temporary phone until then.
Cheers
My phone has been turning off at seemingly random times during usage. It started with the camera taking photos, then when the keyboard was about to be brought up, then right when the boot logo finished, now its when the white HTC boot screen starts. It seems to stop when i plug it in but after it take it off the charger its prone to turning off. I've gone the entire day without it because of this issue. Anyone else experience this / have a fix? Any advice is greatly appreciated at this point.
Its also worth noting i am on the latest FW and am running the marshmallow GPE rom, although i flashed a sense marshmallow rom and its was happening upon boot as well.
I'm still using lollipop on my m8, but my mother in law and I have had awful battery issues with ours. Sometimes it decides to die at 40% battery, seemingly while using barely any ram. The battery icon flashes red and turns off. Many times It won't register being plugged in with various chargers, including a brand new one. When it does, it will estimate several hours to charge, as much as 8!
As I type this, I'm stuck standing by a wall while it charges. It had 100% when I went to bed at 3am and was completely dead when I awoke at noon. (such a reliable alarm clock) I plugged it in and it went from 0 to 40%. Wtf. It estimates 3 hours and 6 minutes until full.
It may very well be a bad battery but it could be the sensor. Found this a while back on Android central, copied the relevant bit below. (http://forums.androidcentral.com/ve...ry-charger-reset-procedure-htc-one-m7-m8.html)
This is directly from HTC tech support. To recalibrate battery and HTC charger when battery rapidly or erratically discharges, this procedure clears all battery stats, coordinates and normalizes charging.
Turn off Fast Boot in settings. Power off phone.
Plug phone into HTC charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons when phone is ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.

Also, I don't know about yours but mine will drain the battery while searching for WiFi. So I usually turn WiFi off outside of my home.
Check out my battery chart. Haha.

i was looking though my closet today and found my old tablet, which got bricked 3 years ago when i switched to a new rom that screwed up my device
well i plugged it into my computer and then i got the battery charging screen you get when plugging in your device when it is turned off, but on the battery it is showing the loading circle on the battery, i have a picture of what im talking about

Keep it in charging for a few good hours and see if it goes somewhere in download or recovery. A hard brick won't even show a battery icon.
Without a working download or recovery mode, there is hardly any help.
Tried with another set of charger and cables?

Hi guys, for the last couple of days I've been having an annoying an constant problem, my phone has been randomly shutting down while browsing or playing a game, the battery indicator suddenly shows 0% and the shutdown dialog shows, but while the phone is shutting down the indicator returns to the previous number, when I connect the phone to the charger or I turn it up again it shows the same battery level that it had before shutting down, sometimes it shuts down right after I'd turned it on and unlocked the screen.

If I don't use it or just do some tasks from time to time the battery lasts until 20% where it shuts down as if it had reached 0% and won't turn on.
I've already calibrated the battery but still happens a lot, can anybody help me, please?

This problem happens with all phones as the battery deteriorates. A battery replacement is required to fix the issue.

yeah, It was, I managed to replace it including the glass back that was cracked (one-day it just cracked by itself) for 20 bucks, thanks
