[Q] Nexus 7 seems to have completly died

I have searched everywhere on xda and all over the web but I just can't find a solution. This is my brothers tablet and he just can't fix it. He bought it new from Comet and used it for a few months and then rooted it. Then a few months later it wouldn't upgrade the android version. It downloaded it OTA and when it tried to install it said error. I ended up flashing the latest version which ended up unlocking the bootloader. All was fine for a while until the stock usb cable had broken, charging worked very slowly when it was in a certain position. So I tried using some other usb cables and it said it was charging but it was ridiculously slow. After several hours it only went up a few %. Then the problem got worse, the tablet said it was charging but it never seemed to go up in battery. I bought a new usb hoping it would work and nothing seemed to have changed. He kept playing on it untill the battery was so low it powered off. Then we tried charging it without powering on and it looked like it was working (black screen with a charging icon). When we tried powering on the battery icon was empty and it went back to square one in a sort of loop. I had looked everywhere and some said we had to hold power down for 30 seconds but it just did this loop over again. Holding power and volume down did nothing, so we were at this one point and it was charging for ages and I gave it another go. Still nothing and after a few attempts it just went completely black and nothing appears on the screen at all. I opened the back without tampering anything at all to see if the battery had come loose and evrything looks ok. I know the warranty has been voided by rooting, unlocking bootloader and opening the back so returning it wont help, and comet shut down a while ago so they cant help. It was quite expensive for us so I don't want to give up just yet. I hope the xda community can help

Sounds like a bad USB port.

So you don't think the battery has any problems? If not how can I solve this problem? Can i replace the USB port or can i buy any docks?

Phone Just Died

So earlier this week, I was using my phone with Google Maps like usual. I plugged in my vehicle USB port to the phone to save battery. I had +50% on the phone and 1A USB port. So after like 5 minutes of it being plugged in, my phone just turned off. I tried turning it back on and all I get is the boot screen, then AXON shows, and puff... Phone off again. I tried booting into recovery but phone turns off before TWRP finishes loading. Phone doesn't seem to be charging. Tried different cables and charger to charge phone but nothing. No charge light. Seems like battery is dead because the phone turns off during boot and battery not charging.
Nothing seems shorted. Phone been working great for weeks before this. BL unlocked, Debloated stock, TWRP. Any ideas other than sending back for warranty? Luckily I still have my S7 as primary but I had my Axon for primary for my trip for real world daily use. Needles to say, photos and videos are wanted off the phone.

Have you tried going to bootloader mode by holding power and volume down
If the battery has died, then the phone wouldn't turn on is my thinking as everyone you then it on it eats some vattwry

You didn't mention specifically, but have you tried using the factory wall charger & cable and leave charge for like an hour?

Original charger but with certified Micro-b/USB-C cable I've been using for weeks between my S7 and the Axon.
So I left the phone alone for the last few days as I was busy at work and Just didn't feel like messing with it when I got home. I tried to turn the phone on but battery was dead. The quick flash of red led was the indicator trying to power it up. So I used my Samsung charger as it was right there and the original ZTE cable. Phone lights up charging and so I left it as is to go to work. I get home, the green led is lit, so I'm hoping my phone will power up now. Nope, right back to my original issue. Power on phone, gets to Axon logo then eventually turns off or goes black screen. I tried booting into recovery but turns off before fully loading. I try to charge phone again but no led indicator.
So later today, I'm going to try to boot into fastboot and try the new TWRP recovery. Maybe it was enabling r/w on system that caused this. I had downgraded to unlock bootloader and then installed ZADmix. I've been usuing it nonstop for 2 weeks with no issues. I have xposed installed so I know rebooted a few times to get everything working and it never turned off since then.
Really frustrating as that's the phone that had my pictures on it.

Hi @RoninBlackSoul, so what did you end up do ? Have you found any way to bring back the Axon from the dead or sent it back to ZTE for repair / replacement ? Same thing just happened to me, and for me Axon 7 is my primary phone ... if the phone is really dead ... will neve buy another ZTE phone ever !!!

Honestly not sure what did it. After battery drained, plugged it in to charge for 2 or 3 days. Then remembered some note about enabling write access in TWRP (something like that) would cause bootloops. Which is weird, rebooted the phone a few times when it was working.
Any case, I reflahed the recovery/bootstack in EDL and got my phone back. Been working great 5 months now

@RoninBlackSoul, thanks for the feedback.
Got mine working also, my phone was not charging at all. After suddenly rebooting and battery went dead fast, phone was not able to charge for about two days. After which, suddenly started working again, was able to charge and works normally now. This is weird. From my point of view this could be: 1. some sort of auto-protection perhaps or 2. an actual hardware design issue that manifests at random (for some after few weeks or months after purchase). For the 1 point: I was using a non original cable using the original charger, and the USB type c plug was hot at the time the issue occurred. Perhaps due to that heat some protection mechanism manifested that got reset after phone was completely out of juice. Will use only original cable with the Original Fast Charger from now on, as the usb-c plug of the 3rd party cable was fine with a normal charger (non QC3). Hope issue will not manifest again or, Axon 7 will be my last ZTE device ...

I only use good chargers rated for QC or 2/2.4 amps like samsung, anker, aukey. Haven't had issues since. Plus certified type-c cables at all times

Help! Battery drained, phone won't turn on, battery charging icon flashes on and off?

My phone had been working perfectly fine, as well as charging perfectly fine. Recently, I accidentally let it drop to 0%, which I don't usually do. I went to plug it into the same wall outlet as always, but instead of the usual charge process, the battery icon with the lightning bolt in the middle simply flashes on the screen and then turns off, which happens over and over again.
It should be noted as well that about 3 weeks ago my phone get fairly wet. After that incident, I turned it off till it dried, powered it up, and everything appeared to be totally ok. No problems since then until this.
Other facts:
-I can safely get into the recovery menu (power + vol down), which is stable, but any menu selections result in the Motorola splash screen for a quick second and then the phone powering down.
-The computer will recognize the connection to the phone.
Attempts to resolve:
-New cable, new usb hub, new wall outlet
-Trickle charge from the computer (same flashing)
-Phone in rice to remove moisture
-Toothbrush cleaning of Micro-usb port (suggestion from another thread)
I'm pulling my hair out, and I am considering prying off the back and replacing the battery. I have searched other threads, but have seen various solutions none of which worked for me. If anybody has any idea how I can fix this please help!!!
Thanks in advance.

Unfortunately most probably is the hardware problem. I had similar issue with razr. Splashed it on the beach, quickly washed with tap water, dryed it and for couple of days like nothing happened. Then suddenly digizer stopped working. It was motherboard. Luckily one xda member donated me the same phone with broken screen so I replaced motherboard by myself.

Thanks for the suggestion. Well, I got it back working again, by charging it for 5 hours straight and then not charging it for an hour. Now it appears to be functioning alright, with the exception that it once went from 40% bat to 15% to 0% in a matter of seconds and I had to repeat the procedure to get it back on. I have another turbo with a broken digi that I could cannibalize but I have no idea what to replace... the battery? Bizarre issue, but I guess that comes with the territory of water damage.

Maybe some part is still wet. If another Turbo has only broken screen, then is probably the easiest solution to take screen from the (ex)wet and put to another one. You just have to have proper screwdriver.

Replaced battery now Droid turbo flashing when I charge?

is my P10 plus dead?

Hello everyone,
i recently acquired a used P10 plus almost for nothing.
the guy i bought it from said it fell on a carpet and it wont turn on anymore.
the symptoms were:
*black screen
*red led blinking (first 3 fast blinks, later only 1 every couple of seconds)
So i thought to myself, probably battery issues from the fall, maybe it disconnected somehow.
I disassembled the phone, reconnected every cable, but still same symptoms.
i read somewhere that red led usually means battery dead or the small charging motherboard (?) is broken. So i ordered both from Aliexpress and installed them today, but still the same issue.
i connected the phone on the charger without the battery, the screen came on (but it seems its broken also - only vertical lines and a crack, lol).
Any ideas?
should i order a new screen and try to fix it or should i give up? (i read somewhere that people couldn't power up their phone after screen replacement)
thank you guys in advance!

well, i guess ill just give up.
i was hoping for an idea of what to do, but nothing.
a shame really, i was hoping to get it back to work again.
cheers!

Nexus 7 (2012) dead, intermittent

Hi guys. I'm a fairly new Nexus 7 2012 (grouper) user, got this device foc from someone recently.
On one day after one whole day of not deepsleeping (due to buggy gapps installation I guess, and it caused the tablet to become quite hot) of a sudden my nexus 7 is reluctant to boot/charge.
Then I try all possible solutions, long press power button, pull out battery leave it overnight, charge overnight... but nothing worked.
Then the next day after leaving it charge overnight, it worked. Then the tablet works the whole day, then dead again.
I put it back to charge overnight, but then this time it is not working anymore. Still dead.
Then I unplug the battery and leave it aside for about one week. Last two days I pick up the tablet and plug the battery back. And the tablet works again! Battery is fairly full.
As at that time I'm using my dot os build, thus I flash back to stock immediately after it came back to life.
Then the next day it worked relatively well. Until afternoon when I was flashing my test builds, it suddenly reluctant to wipe data. When wipe the TWRP will restart. But then I try again and it works, and then it works the whole day. Until when I go back home after work at night, I was bored and install a 2GB game. Then when I open the game, the tablet starts to become not so responsive. I relaunch the game, it shows the game splash screen, then suddenly the screen fade black again like how it is previously. Then dead again.
When the tablet is dead, there's a hissing sound coming from the part around of the battery connector there.
I'm guessing that it is due to previously the overheating causing the solder joints to become not properly contacted. I'm thinking about reheating it but not sure what's the exact problem, as I don't know if the battery is faulty. As the previous overheating is not very very very hot, thus I don't really think that it is the cause of problem.
I'm just a fairly new user of Nexus 7, thus ... trying to seek suggestions from experienced nexus 7 users. Any help is greatly appreciated. Thanks!
*i got this nexus 7 for about half a year aldy, and it's been working fine until recently. Previous owner is a careful user. the nexus 7 infact looks like new out of the box. Never repaired.
