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.
Hello XDA, my virtual phone heros, i appreciate your good work, i am reading here for a few years as a ghost and today i signed up because i am lost with a serious problem on my Note4 N910C (English is not my native language)
THE CONDITIONS AND ENVIRONMENT:
My Phone was first running on stock Lollipop 5.1.1 when i rooted it over ODIN 3.10.6 with space X kernel and CF Autoroot, SuperSU then i flashed the latest TWRP...
After that i flashed a Custom Rom: Sweet_ROM_V17.1_COJ2_N910C...
Everything was running flawlessly for about 2 weeks...I installed Titanium Backup, Xposed, Xprivacy Pro, Busybox and a lot more and made a complete TWRP Backup then, it was running like a charme...The backup is fine because when i messed up my phone through trying harder xprivacy parameters and other tweaking i needed to set it back by TWRP into the old state...
Nothing happened after that, it was running 100% for over a week of heavy usage...
THE PROBLEM:
The one morning i took it from the charger with 100% Battery and went to work...
Before the error occured I did some searching on the internet, used chats. movies, nothing special this day, USB Debugging was On, i remembered something messed up my chrome browser like this ad hijackers, i set it back by erasing data,cache of chrome in the app menu, then there was nothing else strange i remembered, my AF Firewall was closed, only Whatsapp and Browser were allowed to going through...
The same day in the afternoon i tried to use my car charger to recharge my Note 4 as usual, but this time it wasnt recognizing the charger and my first thought was that the charger is faulty or the cable, so i turned off the phone by the androids power menu...I retried loading my battery In the phones off state but when i plug in the charger, the battery symbol came up for short and then it remained dead, it s the same scenario until today, so i used my powerbank to try charging, because the powerbank has an indicator to show the loading state and everytime i plugged it in, it came up for short, battery symbol shows up for a few seconds, but no percentage or animation is showing as usual and no red LED, then its switching off, the powerbank LED indicator stops the loading state after a few seconds, so the loading current stops...
At home i tried the stock charger and it remained the same, since that, i have to charge the battery outside the phone...
The strange thing is:
The Rom is still booting fine, TWRP is booting, but its not going into download mode from Androids Power Menu like before, its always just rebooting back into android if i choose download mode and i have to take the battery out and back in and hit the download mode pattern Vol- Home Power, to enter Download Mode and even the booting into Download mode from TWRP gives the same strange results:
On my Laptop i started the device manager to see the USB hardware string parameters after a windows popup was telling me something like "Device not recognized"
The USB Driver ID dont fit the old right driver ID, it seems to be empty and the port is not communicating anymore
since the charging bug occured,( Everything worked fine the day before.)
I tried my Laptop to narrow down the bug with the same driver i used for flashing phones (S6,910F,910C) over ODIN and my Lappy has USB 2.0 and USB 3.0 ports.
I always used the same USB 2.0 port for ODIN and other MTP stuff, but since the bug showed up the 910C is not recognized at the USB 2.0 Port anymore, seems to be dead in the devices manager table, only the USB 3.0 Port shows it as unknown device with a strange empty ID --> I tried the other devices like the N910F and G920F that are still recognized by ODIN on the same USB2.0 and 3.0 Ports both with the same USB hardware strings, its just the N910C that isnt recognized anymore, in no mode, no ADB, MTP, no download mode, everywhere the same, USB is bricked! Windows finds no driver and says its no info avaiable on this device so I tried to force the right driver to run with the wrong buggy driver ID but its not communicating, ODIN indicator and log remains unchanged...So it seems to be the same situation like other people getting from killing the bootloader by bad flashing, the only difference is that my phone is still booting fine into recovery and even Android but with no charging. My USB Port is totally useless now, its like if Samsung or Google OTA update has overwritten my bootloader or something hidden in the rom that woke up to kill my mods i dont know and now.
PS: Things i tried so far with no results on fixing my issue....
1. Complete fresh reinstall of Sweetrom, 2. Flashing another kernel...
3. Roll back to my TWRP Backup of perfect running ROM but with no USB support anymore:
The Phone remains in unknown state, not affecting ODIN to switch into flash mode
I am sure its the bootloader, since its battery bug is still occuring while the phone is in off state...
Unable to tell the charger the right ID without USB communication...
i was wondering if there is a solution to make a bootloader hotflash from out of Android or something like getting me back on stock first with download mode, forcing the USB ID or communication with a tool out of android, SD card boot image like on note 3 whatever, please tell me! I cant find something related to my USB and Charging ISSUE
PLEASE HELP ME, I am lost
Still the same. It's booting fine, USB2.0 no reaction on the laptop in Fastboot/Adb/Mtp ... On USB 3.0 Device remains unknown with strange Device ID String in windows 10 hardware Manager... Forced the old formerly working driver, but Odin can't find it anymore... Adb, Mtp, fastboot don't work, no communication... USB Cid is hard bricked, Charging never works in no state, just showing up for a few seconds in off state while plugging it in for short.... Bootloader must be damaged, fastboot and twrp can be started with dead USB... So is there a way to run a boot image to fix my bootloader from SD card, Aroma, or like OTA Updates are flashing? If Samsung and Google apply bootloader updates over OTA and simply restart, why we can't do that??? I need a new bootloader, is there any way without USB?
Greetings,
Thank you for using XDA Assist.
I have moved your question to your device's Q&A forum. You'll receive expert advice here. Good luck!
Fixed!
The problem is the USB Connector Port itself, figured it out after bending the inner contacts up with a flat screwdriver and cleaned them. Before that i always tried the same gently with no change, but please do it at your own risk only. After searching for many hours about possible reasons for the problem, I came to the conclusion to even compromise the Port and heavy bending it up, now it's charging! I will exchange the port soon and change the frame too to have it back like as new... OK, if anyone in the future have problems with the bootloader or USB hardbrick n910c, feel free to ask me, I upgraded my knowledge on many causes now
Thank you very much
My 2cents stick to one charger. Do not share that charger with others.
The worst culprit are the cheap china car chargers.
I went thru two USB ports on my first phone to figure this out.
Ever since I have adopted the policy of using only one cable. Never had this issue.
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:

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 ?

Hello there have you been able to fix this?i am currently in similar state
Hi, I really need help. three months ago, some weeks after my Mi 9T overheated on sun (don't know if that has some relation to the issue), it suddenly stopped charging while on, unless I rebooted or turned off. Also, it had difficulties to transfer files to PC and connect to a flash drive by OTG.
Then, I took it to a guy and he said I needed to replace the charging port, and so I did. But only now, after a serious issue. I was changing my rom from MiRoom (MIUI 12) to Evolution X, since the MiRoom's developer ended the rom's support. But It didn't work, It boots into Fastboot mode. I tried to connect to PC and OTG, on recovery mode, but neither worked. The PC doesn't recognize my phone, and the OTG flash drive isn't recognized by the phone.
I bought the charging connector online and paid that guy to replace it. The port feels better, the connector feels way steadier when pluged in, but I still can't know if it charges while on and file transfer to PC or OTG is still not working. So, I'm stuck on recovery mode, in a rom that doesn't boot and a USB port that doesn't work properly. If anyone has a clue of what part I might take to replace or a repair, or maybe a software solution, if that's the case, I would be really thankful.
