[Q] M601 will not boot

Hi,
My M601 (Wifi) used to work fine but one day when I charge it just doesn't display any more. I can see it can charge but when I press the power button it shows nothing.
Is there any way I can troubleshoot to find where is the problem??
Thanks.:crying::crying:

Is it defo off?? Is it not a screen of death?? Hold the power and vol up button and see if it resets. Do you get splash screen or nothing after doing this??

Nothing happened after "Vol-up, power" or "Vol-dn, power". No screen at all.

I faced similar issue , the only thing that was showing was the notification light when charging, after reading all the forums i decided to plug in a micro hdmi cable to the tv so that i can see if the xoom is working.
and yes it was working perfectly fine!!! i could see the screen on tv and the touch was also working but i wasn't able to see anything on the screen(XOOM)
then i finally unscrewed the 2 screws and opened up the xoom , i removed the lcd connection and plugged it again! and THAT WORKED!!!
REALLY!!! TRY That!!!
here is a photo that can help you , you dont have to dig up the whole system, just disconnect the lcd cable and plug it in and be patient please!

[Q] TF101 Completely dead

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.

Could do with a little help, I think my N5 is dead

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

Recovering a bricked uleFone Be Touch

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...

Did you use original charger and microUSB cable?

Yes, i am using a orginal charger and usb cable. I test charger and cable on other phone and everything works . But before that I was charged phone with non-orginal charger maybe two or three times , in period of two months.

Did you get a black screen with a white "X" in the lower right or left corner?
Was there any flcikering on the screen or a Samsung power-sharing notification popping up?
Can you charge your phone with inductive chargers?

When you see that charging sign, press and hold the home button and power button at the same time.
This worked for me. Now my phone is charging normally.
