Nexus 7 2012 not charging and power off just restarts the tablet - Nexus 7 Q&A, Help & Troubleshooting

Ok so i had a Nexus 7 2012 installed into my car dashboard.
Some time ago the tablet stopped charging. I assumed the usb port was broken (had to jiggle it to charge sometimes) so i went ahead an tryied to clean it with a niddle while it was still on (stupid, i know). It still didnt charged and i tryied to power it off. It powered off and then it came back on. By itself. It was strange. I tought i short circuit it so i pulled out the battery and went to buy another daughter board for the usb charging port. The daughterboard came and i replaced it. Same problems.
Then i assumed it was a software error (the tablet had an unofficial lineage os installed). I booted into recovery and whiped cache + factory reset. Then the tablet went into bootloop. Powered back into recovery and plugged in the usb to the laptop. Surprisingly the laptop recognised it. I used Nexus Tool Rootkit to go back to stock rom but even after going back to stock rom, the tablet still wont charge.
Any ideeas on what might it happen ? How to fix it ?

[Q] N4 won't boot, isn't recognized by any computer (adb, fastboot, etc.)

A couple of weeks ago my N4 decided that it didn't want connect to my computer. I tried windows xp, 7, and osx. I tried 5 different usb cables that worked with other android phones just fine. I tried all usb ports on said computers. I've uninstalled and re-installed all drivers, using all the known methods. Then I noticed that I was getting terrible battery life. Like 5% gone in 20 minutes with all radios turned off and leaving it in my pocket. I was on the latest verison of PA with the latest verion of franco.kernel and I've had no previous problems with my phone.
So I thought maybe I did something to it like a bad flash, so i downloaded a stock 4.2.2 zip and flashed it (with gapps). The problem persisted. So I proceeded to wipe the phone in cwm in an act of desperation, and lo and behole I was then stuck with the same problem as before, but this time with no working os to boot to, and no way of connecting it to fastboot or adb in order to put any files on the sdcard/ flash it back to stock. I am, however, still able to boot into cwm and the bootloader. Then, thinking it might be a problem with the usb daughter board as whenever I tried to plug my phone into a computer it gave me this:"windows has stopped this device because it has reported problems. (code 43)", I ordered a replacement. Replacement came, I swapped them out, and absolutely nothing has changed. I tried uninstalling/deleting drivers and re-installing them just to make sure, but same results as before. Also, the N4 DOES charge when plugged into a power source like normal.
So the way I see it, I can either keep trying to replace parts, or one of you wonderful people know some crazy fix to my problem. If not, then I could go the other way, and attempt to brick the N4 even further in order to get it replaced (I.e. it's not possible to see whether or not it's unlocked/has a custom recovery). Also, I can enter "download mode" by holding down the volume buttons and connecting a usb cable, but windows still doesn't recognize the device.

[Q] Nexus 7 usb is messed up

Hello and happy new year to all of you.
Unfortunately the year isn't starting well for my Nexus 7 (2012). It doesn't charge when its ON. It's charging when it's OFF!
Fastboot works ok, but usb doesn't work at all when device is ON (neither charging, and PC doesn't recognize anything when plugged in).
I did factory reset, wiped everything, (data, system, cache) flashed stock google firmware from fastboot nothing again.
I cant say that it's a hardware issue because as I said, Fastboot works ok and charging works on AC socket when the device is off.
Any ideas?..

[Q] Bootloop only works through USB connected Computer

Dear All,
I woke up and disconnected my phone from the charger and it started into a never ending bootloop cycle, It was on STOCK. I wiped data, cache and davercks. I installed CWM and installed cyanogen mod though it. Still bootloop. Then I noticed when it is connected to the computer it works like a charm when I disconnect the cable from the computer it freezes and goes back to bootloop. I restarted the computer with nothing running and phone still worked through it? It's a very weird thing thats happeneing I tried multiple things and it still won't stop bootlooping without the USB via Computer.
Edit #1
After a while if I pull the phone out of the USB it works for a while then goes back to bootloop. I thought it was the battery so I switched it with a fully charged one and still same problem.

Wiped H1511 - can't transfer files anymore

Hi, looking for some 2nd thoughts on this before I throw this phone away. I got this Nexus 6P a year ago and put purenexus into it along with TWRP, everything was going great. Had an issue with a car charger, the charger port heated up badly and I couldn't charge it. After messing around with it I finally got it to charge but not rapidly (no big deal). Now I tried to upgrade the purenexus version and had some booting issues. So I tried to mess around with the versions and in the process I accidentally wiped the data on the phone. Now the charger port charges but I cannot connect to the PC (as in nothing detected in device manager, no sound of plugnplay or anything). I cannot boot to transfer files with the wifi because there is nothing to boot to. 6P has not ext SD port so I cant put files in. TWRP has also a sideload on the install version but ADB doesnt see the device in any state (obviously if the pc doesnt see it). Finally, I figure I just had to change the charger port so I ordered a new port, put it in and same thing. Phone charges but not detected by any PC. I don't think there's another way to put a rom image on the internal SD but if there is I am all ears.

Hi... Seems like you already tried all the available options. How about bootloader? Is the phone detected? Try to reboot in bootloader and issue: fastboot devices
If your phone is recognized, you can try installing a factory image.
Just in case, download last adb/fastboot version from Google directly:

Phone not connecting to PC and nothing installed.

Okay so I f****ed up my phone bad.
Everything was working fine. I had a custom rom installed. One day the charging jack stopped working. The phone wasn't charging or connecting to PC. So I replaced the jack from a cheap shop and the mobile was charging once again but wasnt connecting to PC. I didn't mind it. Now after a few weeks the screen cracked and I replaced it again from a cheap shop. I booted the mobile and everything worked fine for 5 minutes and then the phone automatically restarted. This kept happening and then I opened twrp. the screen was working fine now and it wasn't restarting. So I knew the screen was fine the software was faulty. So after a few F**k ups I managed to remove TWRP as well as the Rom. Now the phone is only opening to fastboot mode and I cant put it back to Stock Firmware because it is not discoverable on my PC. I know I can replace the charging jack from official moto store but please help if it is possible without that.
TLDR
no rom or recovery in phone
only boots into fastboot mode
cant connect to PC.

If the USB socked isn't working, there's no other connection to transfer any file to the device.
It's impossible without repairing the USB socket.
