I bricked my device flashing magisk. So, I bought fastboot cable and restored it using KFHD_SRT_v1.3.5- 7.3.0: https://forum.xda-developers.com/showthread.php?t=1951254
After this I flashed custom ROM (lineage OS 13) that I was using before my device got bricked. I faced so unusual problems with USB connection and charging (described below). So, I restored stock firmware again but this didn't help at all....
Problem I faced after restoring tablet:
1) Usb connectivity and charging.
After connecting device to computer there is no reaction on computer or tablet (even no sound and charging!). Same with connecting to charger. Tablet is charging but the proccess is not displayed anywhere (even in battery options in settings), except increasing battery percentages in the status bar. If I connect device to computer or charger and will reboot it (tablet, not PC) it will be recognized and charging process will begin! BUT after disconnecting device it will show still connected to the PC or charger until next reboot...
2)Wakelock and battery draining.
So, the next issue is that device doesn't go to deep sleep and even sleep. I installed BetterBatteryStats to check the processes and wakelocks and found "usb3v3_wake_lock" in kernel wakelocks which prevents tablet to go into sleep mode. It's always in active mode, aproximately 98% of time, so battery draining really fast...
First of all, I thought that problems was caused by installing TWRP, but after restoring to stock had no sense. Even after restoring stock recovery and boot via KFHD_SRT_v1.3.5 it does't help. Also I've tried to flash diffrent Roms with different android OS versions (RR, lineage, AOSP). For now I am wondering what could cause described problems and would like to find solution

Make sure the cable is properly connected. Check for dust that might prevent it going in properly. Try a different cable. What OS are you using? I found where bootloader is dmg or incomplete Windows fails to detect it. Linux on the other hand detects it. Can't use it but you can detect it.
Can you connect to SW Update Mode? Battery out and plug into PC while holding vol up button.
If nothing works try taking it into the shop.

You can root your phone from there. If you have SW Update. I recommend taking it into the shop if you are still under warranty, If you don't have warranty then you can go ahead and root. Just install a patched bin and fls with Smart Flash Tool. It's one of the stickies (How to unbrick, I think)
hi
new to Android nation
I have the same issue when connecting to USB...
And I managed to flash with custom firmware (latest ZEUS version) and I rooted but the issue with USB connection is still there...
Anyway, I wiil try connecting it to Linux to check if that would work with USB connecting
UPDATE:
OK after some digging, I managed to (at least temporally) solve the issue... After fresh installing official 2.3.4 firmware I booted to recovery and from there formatted the system folder and then installed Zeus v7 firmware... anyway, USB connection and charging indicator work fine at first booting to system... As soon as I reboot the OS USB connection (and charging) get unstable, and after third reboot it completely goes away and the device does not recognize anything: if I connect USB cable it does not show any sing (charging indicator does not show battery charging, nor the device offers me to connect in mass storage, windows recognizes only modem but not the USB storage) and when I connect charger, battery indicator does not flash as charging... Battery monitor tool shows that "battery is discharging" even though the battery capacity seems to increase (according to growing percentage of battery capacity)... Is there a some kind of USB server... I am a total noob to Androiid OS (used to be Symibian from its beggining )so I hope you won`t mind if I used wrong terms in my explanation/comment...
I hope my explanation is not confusing
Cheers
UPDATE 2:
After installing Zeus v7.01 update, battery charging recognition got fixed using both USB cable and wall charger...
Anyway, USB recognition by PC problem still exists... But when in recovery mode I can successfully mount SD card to PC in Mass storage mode...
Will keep you updated... :victory:

Probably a hardware problem then....
I have had the same problem for a few weeks now. It started to fail occasionally and right now the usb won't work unless you reboot the phone. If i'm running out of battery, i must connect the charger and reboot for the phone to charge. And when the phone is charged, if I unplug the charger, the phone thinks it's still connected.... that is until you reboot again. It's a pain in the ass because also the phone wont go to deep sleep (ab8500 charger attached wakelock is keeping it awake at all times).
I was waiting for mi carrier (Movistar, Argentina) to update to Jelly Bean so i wouldn't need to downgrade (as i read some people experience CSC problems when downgrading) but I'm starting to grow impatient...
Same problem dude..
Phone Information : HTC Incredible S, S-ON, 4EXT Recovery
I was using SVHD 2.1 ROM from quit some time, since last week, phone was lagging too much and when I connect phone to PC it was not showing me storage options. Phone was charging but I did not see any increase in battery percentage. I wanted to try VIVOKAT by szezso so went for flashing the ROM. This is where the problem started.
I did wipe data, wipe cache, wipe dalvic and wipe boot. After that I flashed VIVOKAT and when I try to flash boot.img, I found that it was not showing me "fastboot usb" mode. I tired different cable with no luck. And as expected phone is stuck in boot animation.
I thought there might be driver issue, so I re-installed HTC Sync but that also did not help.
Later I did restore of backup taken using CWMR before rooting, Now, restore appears to be successful, but phone is not booting, when I try to start it, it restarts into recovery.
can you guys please help me in resolving this issue
I tried with other PC and other HTC phone combination, USB Cable is fine and other phone is detected so I believe my phone's USB is not working.
When I restarted my phone with USB connected windows indicates that device is connected/disconnected and gives USB error. If I click that message USB devices window opens and it says - Windows has stopped this device because it has reported problems. (Code 43).
What options I have now?
I reflashed SVHD 2.1 and kangaroo kernal v19 on which I was earlier and phone booted
will check USB again after full recharge and will let you guys know.
anyone knows if replacing USB port (phone hardware) will help? asking as phone is charging normally when connected to charger but not when connected to PC
Long time ago, my phone had the usb host mode problem when plug in into pc, but can charge at OS. So i didn't bother it because it still can transfer files to PC via USB OTG.
Last month, itself random went into usb host mode when charging and the phone totally cant charge, need to restart then its ok. When i go into fastboot it shows FASTBOOT AC and then FASTBOOT randomly (like gotten shock) and after awhile the problem gone so i didnt bother about it.
Last week, I unplug my phone after i wake up and then itself shows USB HOST MODE, so i tried connect USB OTG and then it didn't works. I thought it was kernel problem so I downloaded ElementalX 18.2 and then i flashed it. Now, after boot, the phone wont charge. It only charge when powered off and RECOVERY mode. Fastboot shows no sign, no FASTBOOT AC or USB, even OTG power. This is strange and weird.
Also, i flashed ARHD 81.0 at older version of TWRP Recovery, and then after i got that problem, i reflash my phone with TWRP 2.8.0.2, at the end it says : "set_metadata_recursive some changes failed" , and the phone can't boot. Luckily i got a nandroid of it so i flash it immediately. It can boot, but the no charging problems still exist.
I later upgrade my TWRP to 2.8.3.0 via TWRP Manager, still get "set_metadata_recursive some changes failed" problem. But, I found out that after i flash the rom, then flash nandroid, when i boot into OS with charging, it can charge in the OS, but not anymore after i went into fastboot or recovery.
And something interesting is, when the phone boot, haven't load the drivers, itself began OTG mode and powered up my powerbank, PLEASE HELP!! Im totally stuck on this!
Does this is a hardware or software problem? Its this the USB board broken or the motherboard? Please respond..
Sorry for my bad English.
Hi everyone!
My nexus 6 got a problem today. After a reboot without plugin, it's won't charge when I connect a cable, won't connect to PC (my cable still work fine), nothing happen, no bolt on battery icon. I turn it off then plugin and it start charging, I turn it on again (with plugin) and everything work fine, but this problem happen again when I take a reboot (without pluggin).
I try both stock 6.0.1 (mob30d) and n beta 2 (npc91k) via fastboot but it still happen.
Can anyone help me? Thanks for reading.
Did you try to roll back to stock using Google's original *.tgz image ? Only then can you be sure that something is wrong.
Does the PC recognize your phone when it's fully booted up (enable USB Debugging in Developer's Options by tapping "build" option 7 times to enable Developer's Options)?
If your device is rooted and has TWRP, does your PC recognize your phone in TWRP mode?
Does it charge in TWRP mode (has a percentage with plus sign next to it indicating charging)?
Does it charge using a wall charger? using a different, known to be good microUSB charging cable?

I use stock rom from Google's original tgz file, I dont use cooked rom or custom recovery or custom anything.
When it's happen I turn it off then plugin, my N6 start charging(battery icon show up). Turn it on again with plugin and everything work fine. It just happen when I reboot without plugin.
I dont have wireless charger so I cant try it.

If still within 1 yr warranty, I'd exchange it. If not, try wireless charger ; buy local so u can return if doesn't work
this might be a pain and idk if you have done this yet but have you tried a factory reset?
