When I turn it on, it stays for a while and shuts down
same thing happens over and over
Does anyone have an idea about this problem?
We need more detail.
How long is a "while"
Does it always do this or is it random behaviour?
Is the battery fully charged?
Have you tried soft / hard resets?
Does the device go completely off or is it just the screen that goes off? (i;e; when you switch the device back on, do you need a long press on the power button or just a quick press?)

it shuts down completely(i need a long press to turn it back on)
sometimes it stays for 5 minutes sometimes 20 minutes
and the battery is fully charged

OK, it sounds like you have the poor battery contacts problem. To be sure, you can do a hard reset to rule out any software issues. If you have no backup program installed then you will lose anything you have installed to the phone however.
So you could go straight to a simple fix for this problem. That is a strip of card to push the battery more firmly against the gold connectors. First make sure the connectors are all clean:

}
In some rarer cases the connector block with all the gold contacts has actually become partially detached from the board - perhaps a hairline crack in the soldered contacts. Hopefully yours does not have this problem though.

tl;dr: Check out whether one of your missing screws has got stuck in the tiny space underneath the ribbon connectors (CHECK ATTACHED PHOTOS)

long story: I'm far from wealthy, but I wanted to get my parents some piece of electronic that they can surf the web and have fun with. I found this cheap used Nexus 7 online and today I've been basically playing around with it all day checking out different roms and stuff.
At one point I had to unplug the battery because I couldn't shut down the tablet. When I did that, while holding the tablet I shook it up a little and heard something loose in it. I noticed there were screws missing. One of the screws was poking out from underneath the charging ribbon. Without taking off the ribbon I tried to wiggle it around a bit with a screwdriver, hoping it would come out, but instead it got stuck inside a little further. I noticed the noise when shaking the device was gone, so I just put on the cover back on and tried to start it. It wouldn't even light up.
I obviously tried everything suggested on the web. Holding the power button for 30s and such. I plugged the Nexus for charging and heard a little buzzing sound coming FROM THE TABLET. I got curious, so I took off the back again, removed the battery and plugged in the USB charger again. The buzz was still there and it was coming from around the charger ribbon. I unplugged it, removed the screw that got stuck inside and the tablet works again. It must've been causing a short circuit, or something.
I'm so ****ing happy, you have no idea.
Thankfully it works flawlessly, the battery is fine and it charges alright.
I really hope this helps somebody out. I thought the tablet was done, but thankfully I'm as lucky as I am dumb.
Feel free to add this suggestion to any Nexus 7 Helper topic of any sorts.
Hi guys
today morning my phone suddenly turned itself off. Meaning that it did not properly shut down but the screen just went black. I had it plugged into my laptop at that point and the laptop registered it disconnecting at the same time it went off.
Ever since then it has been in a comateous state and nothing works when I try to turn it back on.
I tried booting in Recovery/Download mode, with and without the cable plugged in. Did not work
When I connect it to the computer or a charger it now gets incredibly warm/hot. You can still touch it but you can tell it's far hotter than it should be (or ever was in my case).
I have now removed the back cover and disconnected the battery. After that I pushed the power button for a few seconds and re-connected the battery, still dead.
While it was still open, I connected it to my charger and figured out the area which gets hot is this one:

Any idea why this could be or what could have happened to my beloved phone? :crying:
I had its display replaced a month back at some 3rd party repair service but it has been working fine since then. I fear it is related to that.
Thank you very much for any input or help!
It was running Cloudy G3 2.0 and Dorimanx Kernel with stock settings.

Same here bud. Just happened to me about an hour ago on my VS980 (JPC's CM11).
Hi,
So my phone started to act weird while being charged (it was for about month), when battery hit 9, 14, 27, 44 and something near 80 and 90 [%] it acted like cable didn't connect and always at these levels, but I didn't care as long as it charged. I've tried to maintain battery levels between 20-90% (said the most healthy for Li-po batteries) and charge it only via original charger (original cable mostly, then not cheap 2.4 A cable).
Yet, yesterday happend sad thing.
I've plugged my phone as always after hard day at 6% charged and after 30 mins BOOM! 100%! (impossible). I was shocked and couldn't believe it so I did restart it without unplugging it from charger; my phone did reboot but didn't turn on, I've unplugged it, tried again - it's on with 56%, so I think it's ok let's leave it at this level but my phone though differently - every second my battery was drained for 1%.
Since then, whenever I turn on my phone it loses battery like that; while turned off and plugged in it behaves like cable is broken (disconnect and connect) yet displays 0% and random value (75%, 84%, 91%). Sometimes when I turn it on it displays SD card error but it's totally random.
I've managed to take this SS, hope someone knows if it is battery issue or motherboard.

Do a clean/fastboot flash and see if the problem persists.
It did help, but charging problem remains, with these magic steps where cable looks like it's disconnecting.
Thanks for your answer and sorry for delayed reply.

Try another cable maybe, or charge your phone switched off or from pc/laptop/powerbank.

As I mentioned, I've checked every charging option available, yet this problem still occurs, I've flashed global 9.5.1.0 Stable via fastboot without any problems, so I guess it's not USB port problem, yet I couldn't check if it was charging/discharging battery in this mode.
P.S. Yes, I've checked in stock recovery and on turned off phone and I must sadly admit that it still disconnects/connects during charging like it was bad cable.
Summary: Charged phone from a power bank, now it won't charge anymore.
My mother charged the phone from some power bank from a friend, as she describes it "it charged very fast and it was very hot". Then it also drained pretty quickly. Now when connecting the original cable and charger from a power outlet it won't charge, nothing shows up (even after 1 hour).
- the power button doesn't do anything, recovery mode won't work either, not even launching in safe mode
- the cable and charger work perfectly (they tested with the other p10 lite phone they got in the house)
- after connecting the cable, not even the led light won't turn on
Here is the strange part.
RANDOMLY ! It will boot up itself into recovery suggesting to update it, after they hit update, they connect successfully to the house Wifi, it will say something like "package information failed to gather". Other options are wipe/factory reset, reboot, shutdown.
Now, I guess I'll try a wipe/factory reset next time it goes into recovery by itself, it happens randomly, can't be done manually since the power button doesn't do anything.
I told them to connect it to the laptop, to which the phone is showing the Huawei logo for a while, then it disappears. But after many tries, we got it to somehow connect with "fast boot" and I managed to take this screenshot.

}
I then installed Hisuite and tried to connect to their recovery thing, but this device isn't supported for that.
Some final thoughts, I am still confused as to what the actual issue is, or if there is more than 1 issue.
- the port might be fried from the power bank, but then it still works sometimes, just it doesn't actually charge
- the power button doesn't do anything, maybe because the phone is on 0 battery
- the phone data is corrupted somehow and it won't load the OS, because after connecting to the PC instead of finish loading the OS (after the huawei logo) the logo disappears and nothing happens.
I'm hella confused about this situation. I also told them to use a toothbrush to clean the usb port, still no results.
Any suggestions?
Hello,
First of all, thank you for taking your time and reading my post.
Recently I purchased the android head unit for my car. During the installation process, I quickly connected the cables to test the unit before mounting it. The unit turned on and booted without a problem, but the screen was upside down, so in order to mount it, I had to rotate the screen. I disconnected the screen cable and the digitizer cable, rotated the screen and reconnected the cables. After testing the unit again, there was no display! The backlight was randomly flashing and I was even able to hear the radio. So the unit was turned on, I had a problem with display. I made a mistake: I didn't take a photos of screen connectors, so I think I incorrectly connected these cables. After several attempt, I pressed the RST button for a while. I thought I was a software problem and pressing the RST button would RESTART the device. But after pressing the RST button, the unit is dead. It doesn't turn on, anymore., the screen is black, no backlight. When connecting power cable, the LED lamp near the CPU is turned off. I tried to connect it to the PC using a USB cable. When I connected it, nothing happened, no new device was detected on PC. I checked the fuse and it is OK. I also recognized some testing points on the motherboard and these points appear to have correct voltage, 3,3v and 5v.
However, the LED_VCC is 0 and LED+ has 0 voltage.
I haven't flashed any custom firmware. Is there any chance to recover the device? Maybe I need to follow some instructions after pressing the RST button?
I've attached some photos of the device.
The CPU is: UIS8141E,
4GB RAM, 32 GB ROM.
It should have android 12, however I didn't have a chance to properly identify the OS.
