[Please help] OnePlus X bricked, not detected by computer - OnePlus X Q&A, Help & Troubleshooting

Hello,
I am left with a OPX with no ROM, and no bootloader (after trying to upgrade TWRP). It shows the Oneplus icon, and Fastboot mode works.
I'm trying to access the device through adb or fastboot, but my computers can't detect nothing.
I installed Qualcomm drivers, ADB & Fastboot, Oneplus USB drivers. I tried to connect my OPX with Fastboot, and with "volume up" plugging (as shown in the mega unbrick guide), nothing shows up in the device manager.
What can I do ?
Thank you very much.
NOTE : I was not in developer mode on the last ROM installed ...

Since fastboot works it seems that your PC or maybe the conection might be the problem here.
Have you tried different cables, USB ports, different computers or different Operating Systems?
Could your MicroUSB Port be broken?
( You could give Ubuntu a shot. It might take a little time to install, but it's free and if you can save your phone with it it could be worth the time. You can also unbrick your device under Linux once you successfully connect it in EDL mode. )

Redmi Note 3 Pro ist not recognized

Hello Guys,
I would like to flash a Redmi Note 3 pro with twrp.
The problem is it is not recognized by PC. It's not even showing anything in device Manager.
I installed usb drivers from Xiaomi, I booted to Fastboot Mode and connected the Phone to the PC. Nothing is happening. No device ist showing in device Manager.
I tried 3 different USB cables and also to connect it to a notebook instead using my PC. No Chance.
Then I tried to connect a Redmi Note 4X in Fastboot mode and the same happened. IT IS Not recognized and the device manager don't show a new device.
Both phones are officialy unlocked.
Anyone who faced the same problem and can help

Hi, so you have tried 2 PCs, 2 phones and 3 cables. I think you missed it in the Device Manager. Please connect your RN3P phone in fastboot mode and run http://www.uwe-sieber.de/usbtreeview_e.html then do File/Save full report, and post it here. Alternatively, run any live Linux and post lsusb output.
Thank you for your reply.
As it seems I can´t post links because i`m new and when I try to post the report here it says I can`t because it has more than 30000 caracters
But as I said it won´t be recognized. Both of them won`t.
When I connect them in working mode I can´t even access the data like pictures etc.
One of the 3 usb-cables were originaly packaged as I at first suspected the usb cables were faulty.
But now a friend of mine come by and I tested to connect his Redmi note 4x and it is working. The only difference is that he has miui 8 and I have miui 9 from xiaomi.eu.
So I am out of ideas now. The only I can imagine is that both usb ports on the smartphone are ****ed and therfore it won´t connect properly.
Charging is no problem by the way
Bro you have to setup adb drivers perfectly a single error in setting up leads error but no worry it would not harm your device....
So first of all setup adb driver from the given link it will show you how to setup adb driver
Then go your processor of setting up twrp.
If you need any help on setting up twrp just reply on it....

Pc does not recognize moto x4 in fastboot mode

Hello everyone, before I decide to create a topic in the community I want to report that I tried "everything" to solve my problem, I searched the internet for solutions and nothing, I believe that I will have a light here.
My moto x4 device with android 9 is recognized by the pc when it is on, but in fastboot mode the pc is unable to recognize it, I have already downloaded all the necessary drivers, tested on two different PCs, used all the USB ports, installed the ADB and FASTBOOT, gave the command via cmd to restart in the fastboot, but it simply seems that nothing I do is able to fix this, in the device manager the following information appears:
unknown usb device (device descriptor request failed)
I've tried to update and uninstall, but nothing happened too, remembering that when the device is on it works perfectly on USB.
My operating system is windows 10.

Help needed! Recovery mode disappeared.

Hi all,
I tried to flash the latest TWRP but for some reasons it's messed up. Now I can't enter recovery mode and just wondering if there is a way to re-install it.
I tried to do it via Fastboot mode but my PC(windows 10) can't recognize the phone when in Fastboot mode. I tried several ways(e.g. reinstall USB driver, remove / install driver via device manager, etc.) but no luck.
Any help/suggestion is appreciated.
Try with the original cable. It will work for sure. I had almost the same issue, tried various drivers, etc. Once I've connected the phone with its original cable, it was recognized instantly.
Strange, other people say, the original cable is bad quality??
I would use a different cable but an usb port on the mainboard no a front usb port.
Also i do all the adb und fastboot stuff on a linux machine, it's less struggeling with drivers then.
The original cable still works though, I'm not so sure what bad quality can that be... And yes, I haven't used it in these 3 years more than half of the time. In the past year I was using a 3m Ugreen cable which didn't do the trick for drivers, still working well.
However, with some changes in the kernel or whatsoever, the original cable doesn't charge the phone anymore while connected to the computer, but it ensures a good data transfer.
PS: USB type-C is more complex and not standardized for all manufacturers, which is a bit surprising, but that's it.

you need to format whole phone in oder to be recognized by pc.try first deleting all drivers for x2.go to windows in device manager,reboot pc and reconnect phone to pc by using usb type c cable
thank you for all the recommendations. I will try original cable and other PC using Linux and see if that works.
Update: My windows 10 PC installed the wrong driver when phone is in fastboot mode. Working fine now after deleting it from Device Manager and reinstalling.

ADB not working on Recovery/Fastboot mode.

I am trying to root my old phone Samsung Galaxy core prime G360h so that I can gain some confidence to change the stock rom of my main device. When the phone is on, adb works perfectly and recognise the device. I can even reboot device when the phone is unlocked. But once I go into Fastboot/Recovery mode then ADB fails to find the device and no commands work(.To the best of my knowledge, I have all the necessary drivers. I have tried multiple USB slots, multiple computers (Windows 7 sp1 and Windows 10 latest update), and have searched all around the internet and various forums on XDA for an answer. I've tried manually updating the USB drivers through device manager, installed universal usb driver, but that did nothing. What I don't understand is that how ADB works when the device is on but don't work when it's in Recovery/Fastboot mode. I would have post images to clear things but the site is not letti g me to post imaves
tldr: adb recognize phone when it's on but Adb don't work in fastboot/recovery mode
Thanks in advance for any help, I've tried everything I can think of.
On MediaTek devices you need Preloader VCom Driver so your PC would detect your phone on fastboot but on Qualcomm ( which is your phone chipset ) i don't know what driver is required ...

Mi A3 not recognized when connecting through usb, cant unlock bootloader (Windows /Linux)

Hey everyone
I'm trying to unlock the bootloader on my Mi A3 (M1906F9SH running stock A11), but for some reason my computer (Windows 10) isn't recognizing it. It doesn't even show in device manager. "adb devices" doesn't identify it as being connected either. Having the phone on, in fastboot or in recovery makes no difference (in recovery it shows the "no command" error). I've tried 3 different usb cable and 3 different usb ports.
Ive tried reinstalling adb drivers, qualcom drivers, ran the 15 seconds ADB installer (again). Tried to add it as a legacy device in device manager but nothing worked.
Then I tried using Linux (sepcifically mAid) but it didnt recognized my phone either.
I recently installed a custom ROM on my poco x3 (and I did so a couple of times in the past with different phones) but it was never this difficult. I honestly don't know where to go from here.
Am I missing something?

same problem with me
i am also using mi a3 evolution x 7.2
my computer (windows 11) again and again connecting and disconnect usb.
maybe usb port has bad connection.
is usb debugging enabled?
i used ubuntu to root my mi a3 and to install custom ROM, it should show something when in fastboot mode.
