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.

My phone has started to do odd things regarding battery charge level. Have tried full-charge-delete-batterystats more than once, tried restoring older version through CWM and that doesn't seem to fix it.
This pic shows the behaviour quite well:

The phone was shut down (with fast boot enabled) over night, and appeared to be off, but it was draining the battery quite fast and reports that the display was on, despite this not seeming to be the case.
Disabling fast boot cures this, but it never used to be a problem - I've used fast boot for months without this happening. And I quite like the fast power up.
I think put the phone on to charge, and it often seems to charge really slowly. I did a full reboot and left the house. Rebooting caused the charge level to jump up, and then it discharged as I used it quite heavily, before putting it on to charge when I got to work. Other times, when I do a reboot it'll drop 30-40% in charge immediately!
the phone is about 16 months old and maybe the battery is just worn out ... or is there anything else i can try which might fix it?

Hi,
WIPING BATTERY STATS, IS A MYTH
Looks like it might be worth trying a new battery.
That spike in battery % left when you rebooted looks like the standard Sensation battery goofiness... I replaced my battery at about the same age that yours was and its performance had definitely degraded quite badly. It would discharge much faster than when new and charging took longer as well. Replaced it with an Anker 1900 and it's better than ever. Lasts all day and charging is nice and fast.
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
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 I was having battery issues when I noticed my OTG had stopped working. But what's worse was the USB port was not either, so now I have no way to use fastboot and RSD Lite. Not good. So I installed a new OEM battery and USB port. The battery would not even take a charge and phone just bootlooped instantly. Reinstalled original battery, which now seemed to be charging much better for some reason. But the USB port still did not work, although it will now register as a unrecognizable device on Windows 8. A pop-up says there's an unknown issue with the device and to try again. Drivers are fine. I really want to restore the phone to original factory settings, meaning the original boot kernel, etc. I had upgraded the fastboot, radio, and recovery to a material look and I doubt that is related, but I still want it factory so that it will take OTA updates and I can sell it to someone who just wants a phone which does what your average owner needs it to do, lol. So anyone have any ideas? Is the main board toast?
Delete the drivers and reinstall.
Already done. No help but ty.
I forgot to say that I have 2 Nexus 5's, I upgraded to the 32Gb when my original 16Gb started having battery issues, which, I might add, I resolved this morning by booting into bootloader and allowing it to charge in that state, so it stopped looping the "dead battery loop" as I called it, and charged up to 95% by the time I rebooted into the OS. Seems to be working fine now, will check battery drain soon, but focusing on the OTG/USB port issue. I'm thinking the battery issue is related. I think I somehow connected it to too much amperage and cooked the main board's USB infrastructure, if that makes sense. So it might explain the battery issues also. Now it has a new battery, and all is well there at least. Oh, and I get a screen I have no idea where it came from. It comes up only when the charger is connected but the phone is off. I will try to get it up on here.

Idk if that first try came out ok cuz I don't see it on my phone, so I put up a link, does anyone have any idea why that is coming up when plugged in and not turned on? Weird.
And does anyone want a N5 16Gb w/ unlocked BL, MultiROM flashed and stock, rooted Android 6.0 and CM 12.1 installed? Cheap money? It just can't be connected via USB except to charge. But battery is brand new, ? Great as a dev device, should keep getting ROMs and official updates for years to come, look at the N4, still getting love, and the N5 is far more popular.
Oh, and screen is mint condition, and casing is good but for a couple little flaws, but it's a great functioning phone but for the OTG and fastboot problem. But no matter, it can be worked around, just don't fully wipe it, lol
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

<- sorry for the low quality
when i try to attempt to get into download mode i cant get into it it just shuts off and i plug it in again and in around 5 minutes it will go back to the screen on the picture
i have installed the samsung drivers and kies, and i still cant get it unbricked, if possible, give me tips on how to resolve this issue, because a extra tablet could be handy
thanks,

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?

i would have a extra charger if my tab didnt have a iphone like charger instead of a micro usb traditional charger
