The device 703L does not turn on, it is charged via usb. The PC does not see it. There is no physical button + sound. As it turned out, the firmware was KangVIP B212v4 and for some reason EVERYTHING was removed from the recovery (all checkboxes were checked). Are there any considerations in this case?
Maybe the battery is dead and needs to be replaced. I have an old Mate 9 that I use as a loaner when I fix someone's phone. All of a sudden it just didn't turn on. I replaced the battery and it works fine now.

Looking for thoughts and suggestions.....
My Vadafone 845 (Huawei U8120) went through the wash the other day. I took the battery out as soon as I found it and let it dry out for 2 days... turned it on and nothing.
So I baked at 60 degrees for a couple hours (with the battery removed) and now it turns on but doesn't boot the OS. I just hangs on an hourglass in the middle of the screen.
Interestingly, the phone will not turn on when the charger is connected or if it is connected to USB. If I turn the phone on and then connect the USB, the phone doens't turn off... I can even remove the battery and the power via USB keeps it going. Unfortunately, the computer does not register that a device is connected.
Recovery and bootloader modes don't work.
I can however get into firmware update mode and was even able to successfully update the firmware.... with no change to the phones behavior.
So does anyone have any thoughts on how I might be able to resurrect my phone?
So today I was using my phone and then i could turn the screen back on. So i pulled out the battery and tried to turn it back on, however it didnt work. I tried plugging in the charger, but there wasn't any orange charging light (it was on around 60-50% battery when it stopped working). I tried connecting it to a pc, but there was nothing, i couldnt access the sd card and there was nothing on the device manager. I tried doing the volume down and power button and other stuff, after a while i managed to get the phone to boot up but it died before it made it to the lock screen (not charging). Is there away to fix it?

Try removing your battery and then plug in the cable connected to PC USB. I would also try doing the same with a unix based system, just to be sure that there are no driver issues(though windows should at least show an unrecognised device in device manager).
Also, can you keep it on charge for some time and see if the phone feels a bit hot...? If not, it seems to be hardware fault.

Maybe your phone is bricked,but the way you explained it seems like a hardware problem !
Do you have warranty ?
I have a d850 that I bought used. It came with the stock updated image.
I rooted the phone, used an autorec app from the store to get TWRP on it, took a backup of the rooted image, (after much failed fiddling with other methods) and flashed the latest CM nightly for the D850 on it. After much fiddling, I finally found a GApps package that worked and flashed that as well to get CM working properly, then took another backup.
At this point I was pretty happy that I had everything working how I wanted. However, I paired my phone with my vehicle (bluetooth) and shortly afterwards the phone shut off.
In this state, the buttons on the phone produce no result. I tried a battery pull, plugging it in and some other shenanigans and nothing worked. Just when I was about to declare it bricked, I discovered something. If I pull the battery, and then plug the phone into power, the error screen comes up. At this point, I could reinsert the battery and the phone would switch to the powered off charging mode (green battery icon). From here, I can reboot the phone into recovery mode (via button pushes), but only if I remove the charge cable once the LG screen comes up. If I don't remove the charging cable, the LG screen comes up, then the phone switches back to powered off charging mode (green battery icon). From recovery (TWRP) I can boot the system back up normally and everything runs fine. I can reboot the phone without issue. However, if I power off the phone, I have to play the pull the battery, plug the cable game again.
I have no idea what portion of the phone (bootloader, recovery image, image, etc) controls what the buttons do when the phone is off. Anyone have any ideas on what I have hosed or how I can fix it?
UPDATE: I found a second method today. Inserting the battery while holding down the power button will also boot the phone successfully. Still clunky, but less clunky.
So I decided to update to OTA 4.1 today and finally got everything to work (but did not connect to the internet). I got home, connect to my home wifi, and left to charge. Came back from dinner with a dead tablet without a battery charging screen nor ability to turn on the tablet (long hold power or long hold power + vol down). any suggestion on what I can try to do?
[UPDATE]
Left the tablet plug in over night..seems to be fully charged, per the green LED charge light. However, still refuses to power on. This is the old B1 battery tablet. Assuming that I forgot to flash the nomoreota.zip and the kill switch is activated, will the tablet refuse to turn on?

Technically, the tablet does turn on, but the kill switch modifies the staging partition so it can't boot anything.
darn.
Hi,
First I hope I'm posting this in the right place - to get assistance/direction that will help my situation. If not my apologies - please send me to the right place.
I have a Nexus 5, Android 5.0.1, Rooted.
- My device was charging then suddenly went into boot cycle - showing the Google logo then powering off and repeating the same. Trying to get into recovery mode was impossible - would power cycle out of there too.
- I have tried doing the multiple fast press, and sticky button clean solution (actually taking the back plate off etc.) posted out on the net but that has not resolved my issue.
- Left my phone to charge overnight. The problem still persists. More accurately. Turning it on without it plugged in to the charger does nothing.
All the following is the behavior when its plugged into the charger:
- Without pressing any button just shows a full battery charge icon for about 8 sec then the screen turns black for two seconds and that keeps on repeating. If I press the power button it shows the Google logo for a 1.5 seconds and shuts of, going back to the battery charge icon flashing cycle.
- Now if I press the power and volume down button It takes me to the fast boot mode screen where can cycle through the menu's <Start, Restart Bootloader, Recovery mode, power off>. None of the options work. No matter which I chose the phone shuts of and goes back to the full battery icon cycle.
- I was thinking a battery issue but, when in recovery mode the phone will not turn off. I can use the volume buttons to go through the menu as pointed above but using the power button just takes me back to the battery icon cycle. Now I'm not sure, battery, power button or software. What could it be?
I am thinking, try a new battery or, damn buy a new phone (my phone has outlived its warranty). If there are any ideas on fixing this I'll appreciate your opinions. If i have to get a new phone is there any hope of salvaging data. I have a 4 month backup on my computer, but my latest is stored on my phone.
Thanks.
If you run into this issue and none of the solutions in my original post apply, read on in case my final solution helps you out (you might not even have to get paid help if you know how to work on the fault I was experiencing). If not - nothing more for you to gain if you read on.
As it stands:
I took my device to a reputable cell repair shop. After describing to them the symptoms of my device the out ruled the stuck power button issue and tentatively diagnosed it as a firmware bug or nand memory corruption issue which would require a nand mem flash which they had the tools to do. I went for it.
When I went to pickup the device. They reported that the device was functional and they did not even have to do the flush. My data is safe. Issue was a loose battery contact which they detected and fixed. It's been 8 hours and all looks good. These guys were going to charge me a $80 bill to do the flash if the recovery was successful, but I had to leave a $56 deposit after tax for them to begin the work and pay the balance if the procedure was successful. When closing the deal they just gave me the device and said since they did not have to do what they anticipated, the deposit I left them was satisfactory.
I have my device back and working (at least for now) and have the chance to make external backups incase the issue reoccurs. I'm happy. Cheers.
