I get device descriptor request failed when I connect Samsung A30 to computer. I tried to install drivers, change the cables and connect to another PC, I also tried to factory reset the phone. But i still get this error.
Phone is charging but not showing usb options and is not connecting to pc.
Might be problem with your operating system. If your bootloader is unlocked, go through the flashing firmware steps regarding your device.
if not yet unlocked bootloader, proceed to the service station as there's nothing with in your hands

I try to get in bootloader but that message show:
i cant power on the phone or open recovery
BOOTLOADER
90.78
CODE CORRUPT
BATTERY OK
OK TO PROGRAM
CONNET USB
DATA CABLE
Try connecting a USB cable to a PC and flashing an SBF file...
im writing in the name of MotoMileCm7
i cant use RSD at all, the phone just not loaded into the software, like it`s not connected to the PC
and i cant get to the OR, it directs me straight to the flash screen
help pls
Does the phone still say "CONNECT USB DATA CABLE" even when a cable is connected? If so, try another cable/USB port/PC.
If you've tried at least 2 cables, 2 PCs, and more than 1 USB port on each PC, then you might want to contact your provider for warranty options. They'd never know you rooted/flashed it in this state, as the code on the device is corrupted and sending you straight to the bootloader.
I had the same issue .....i had to send it for repairs
Hey guys,
recently i found myself in a sticky situaiton, my USB connection to PC stopped working. Stometimes charging doesn't work until I reboot the phone, random car mode etc...
I tried everything, from reseting my ports on PC, reinstaling drivers, wiping phone cashe, factory reset and so on. PC just says "USB device is not recognized" .
So I wonder how to make the phone varanty possible without USB connection. Maybe trough terminal emulator?. I had TWRP recovery installed and I flashed stock recovery image directly from it, but it's still tampered and I have to get rid of it before taking it to store for varanty.
Any seggestions? I'm pretty desperate, pretty sure it's usb port on the phone or motherboard.

you cannot remove tempered from bootloader and it will show relocked. Its there for a reason, so HTC can see if you been tampering with the phone.
Yes it does void the #warranty.
That said, I send my phone to HTC to replace charging port and they did not charge me .. Have the phone for over 3 years and its rooted.
Tak to HTC but bear in mind Depending the country there's a 50% chance they will charge you.
Anyone with the same issue ? I am stuck at the bootloader since I wiped out my system image I can get to the recovery but I don't have a way to transfer new ROM since phone wont detect USB (MTP).
I didn't have any image backed to restore to. Tried OTG cable/USB nothing worked
What are my options ?

Hi... Is data mounted and MTP enabled in TWRP?
Is your phone detected while in bootloader?
Try: fastboot devices
If phone is recognized, download stock firmware of your choice and flash it...

MTP is enabled but phone is not detected at all
I can access the terminal in recovery mode but it doesn't support ftp command to download any firmware.
I guess I am doomed

Wait... I don't get it...
Are you stuck in recovery? Or bootloader?
Also you can't use ftp commands either in bootloader or recovery... I suggest you start by reading this thread to learn a few basics about Android commands and how-to :

Sorry to confuse you I can get to the bootloader and the recovery no problem but when I try to reboot to the system it kept saying no OS installed. I don't have any ROM installed and I can't use USB cable since phone won't detect it. So I am stuck at back-end.

So...
What operating system is installed on your computer?
Did you already install adb/fastboot drivers?
In device manager, while being in bootloader, is your phone detected when you plug your USB cable?
Did you try different cables, USB ports?

I tried different cables/PCs nothing worked. I think my phone USB port is defected but what confuses me more is that it can be charged just fine but no USB connectivity
It is still under warranty but not sure if it will be honored since I have the bootloader unlocked.

Nothing like said it is dead. I have another nexus 6 can connect easily to the PC I am pretty sure it is a phone issue.
Well, if you're 100℅ sure the USB port is damaged, there's nothing else than a repair that could bring your phone back to life... Good luck..!

Tried that already it didn't work
Might be a driver problem.
Connect it your windows pc and check the Device Manager if it is detected as "Android" device. If so uninstall it and disconnect and reconnect it to the pc. Let windows install the MTP drivers.

This has already been discussed if you read the "few" previous posts ... Device isn't detected at all...
Hello all, I have a strange problem on my xiaomi 8 phone.
Every thing works fine, the phone is BL unlocked, with global rom installed and can be OTA-updated.
Now I want to re-lock the Bl (because of google pay), so I booted to fastboot and the strange thing happens. When I connect to the usb port of my win10 pc, nothing happens, the device manager also show no new device or unknown device. And I als connected to my ubuntu server, dmesg show nothing, and lsusb also show nothing new.
So the issue is, in fastboot mode, my phone seems not be responsed the usb connection. This is boring, because I also accidently replaced the twrp with stock recovery, now I can do nothing on my phone without the fastboot connection.
Any one has an idea or simillar issue and have a solution for it? Thanks in advance.

It sounds like you accidentally relocked the bootloader.
If so you will need to repair the phone in EDL mode by using QPST. There are plenty of how to guides available. You can buy a EDL cable from Amazon
