USB port broken - Alternatives to transfer files? - Redmi K20 / Xiaomi Mi 9T Questions & Answers

My phone felt in the water yesterday and I think my usb port is broken now . Can't connect to pc via usb, adb doesn't recognize my device but fastboot and charging are working fine.
Before I knew that my usb port wasn't working, I decided to flash a new custom ROM (was in LineageOs and decided to try Havoc, android 10) so I formatted the data and lost everything. After formatting that I discovered that I couldn't connect to pc :/
So I went to fastboot and tried to flash Global stock rom and it didn't work. The process went smoothly, but when booting I got stuck in MIUI logo screen.
So I tried to boot with chinese rom and everything went well, but I still can't connect to pc to transfer files and I don't want to keep with MIUI.
Is it possible to flash a custom rom without wipping all my data? What are my options?

use ftp like filezilla to copy files

Try reinstalling the drivers, or use a different computer. If you don't have an other one and reinstalling does not fix it you could buy an usb-c otg adapter. For flashing the data partition has to be wiped prior to installing a rom so it's not possible to copy the files from the cloud.

I solved the problem by not formatting internal storage. Just installed Havoc and its working fine now.
But the problem probably lies in my usb port, as fast charging is not working anymore aswell

Have you made sure that it is set as MTP?
Setting - Storage - USB.
Check if the device gets connected in Fastboot mode. If it doesn't then it would be your USB.
sideload is not working either
usb is brand new and original.
is there a way to flash stock rom via recovery?

USB Device not recognized on Windows

I have a dilemma. This morning my usb was working fine but I needed to get back to stock and unrooted. I flashed the system.img from the NDR90X factory image and wiped my data (not userdata however because I didn't want to lose everything) the phone booted up just fine and operates fine, other then it doesn't mount on my pc anymore. fastboot and adb do not work for me either. I tried mounting on both windows and linux, I tried using another computer, and I have tried mounting through the recovery. none of these have worked. I cant try going back to complete stock because fastboot is not recognizing the device either. the phone still charges fine with no problems. But I still am getting the feeling that maybe the usb port has malfunction. I was hoping that maybe someone could help me with this problem and reaching a solution. I don't know if I can contact google about this problem because my device cannot be returned to completely stock.
I forgot to mention that after flashing the stock system.img I also flashed TWRP, and since then I am back on a custom rom to see if maybe that would fix my problem. However it still persists.
I have uploaded a picture showing what error message I am getting on windows.
Reinstall the USB drivers

Turns out it was the USB that doesn't work. When I got home I tried another USB that I have and it works fine.

LOOP

My x722 has a boot loop, and I had not enabled usb debugging on it, now or the pc does not recognize, there is some way to solve
I had that Problem, too!
But I got it back going!
First, try to get into twrp again and re-flash your Rom+ Gapps.
If you have any other working ROM on your internal memory, you better flash that one!
If both is not available, conneect your leeco via USB to another phone and there, activate Media Transfer! On the other phone, you should See your Lex722 and can now send Files to it. Just replace your Pc with another Android. For me, that worked to get it going after hard brick. Was not recognized by PC and booted only into fastboot. Data were formatted...

[Q] My PC doesn't recognize OP5 but charges.

Hello all,
My oneplus 5 was using on pie with TWRP installed for few days. Then one day I decided to change rom. My PC doesn't detect the device. I checked in both linux and windows. None works.
Tried Methods:
Adb
Changing usb mode to MTP/File Transfer
Recovery mode.
Fastboot Mode.
Qualcomm Mode.
Checked usb-devices,lspci -v in linux but doesn't return device.
In windows the device manager doesn't show any entry.
Now I did a stupid thing. Thinking this as some kernel fault I shared rom files from one mobile to my OP5 using shareIt and flashed the rom and stupidly formatted data. Internal is formatted so no way to recover my mobile.
You tried a different USB cable? I had the exact same issue and it was actually the USB cable that was faulty but it had worked perfectly fine in the past. Also try a friends computer or something, even though this is a slim chance.

Question about flashing custom ROM without pc

Back in 2014 my device stopped charging with USB. I just happened to find it the other day and put it on a wireless charger and lo and behold my Nexus is alive again. Back then I used to do a lot of flashing ROMs but I'm very rusty now. It has a custom rom called Vanir on it and is rooted and has twrp. If I just download a custom rom to the device will I be able to go into recovery and install it? My laptop just died on me and I can't use it to flash the ROM. I just want to try something different for fun.
Thanks!
Edit: the USB won't work even if my laptop hadn't died.
Download custom recovery to internal memory. Make sure it's not saved in to system directory, but internal sdcard directory. Boot in to recovery mode, wipe cache, then chose install and find your custom ROM. Press install. Make sure custom ROM is definitely made for your device and was confirmed to work without any issues. USB stops working for few reasons. First and easiest to fix is damaged USB socket. You can replace it by buying a new or second hand one. Second reason is short on OTG activation pin. If its's shorted to GND, USB charging will not work and no communication with computer possible. There is a lot of possibilities where this short could have happened. On my 3G device this happened under main processor, and the only way I managed to revive it was injecting 1V to OTG activation pin, which somehow made short disappear.
