Question Fastboot screen usb dont works - Xiaomi 12S Ultra

I have an MI 12S Ultra that I was using with the MI14 ROM. But I decided to go back to the old rom (MI13 ROM).
I did the procedure via TWRP and the phone only logged in via recovery.
I checked that I wasn't accessing \data.
I formatted /data/ via TWRP and the phone is only in fastboot, not being accessible via USB. Can someone help me?

May be a Twrp problem at the start, rom A13 and Twrp A12.
Do you still have access to TWRP?

No. Only fastboot display in screen.

Is possible to use EDL cable in this model?

(Q) Wiped everything and left with no OS or backups.

Hello,
I wiped everything during a ROM change. My device will still go into Fastboot and TWRP. Is there a way to push it trought fastboot or adb. How can i fix this problem?
What recovery are you using? If you're using TWRP you can just connect your phone to your PC while in TWRP and copy a ROM zip across. Or you could flash the stock images with fastboot, see section 8 of my guide thread for instructions on that.

I tried to flash the stock images. Everything went fine and smooth but when i tried to reboot it get stucks in de "One plus powered by android " boot animation. I can still enter Recovery ( it went back to stock unrooted i guess) and fastboot.

[Q] [HELP] Is this brick recoverable?

Hi,
I'm new to the Android community and I was making some improvements in my XT1039. I unlocked the bootloader, flashed the Retail 5.1 for the XT1040 model. It was running fine, then I removed the bootloader unlocked warning and still fully functional. Also, I've flashed the TWRP recovery and everything was smooth. Then I tried to perform the root and I couldn't initialize my phone anymore. But I still could access the TWRP recovery. Then I started wiping to try to solve the problem, but the thing is that now my phone has no OS and can not initialize. It stops while in the Motorola loading screen.
I can fastboot, access the TWRP recovery and all, but there's no OS and my computer doesn't recognize my phone. while connect through the USB cable.
Is it possible to recover the phone? I was thinking that the solution would be to flash another firmware to the phone, but itsn't working.
Could anybody help me? It must have an alternative to fix it, I couldn't figure it out yet. Can you?
Thank you in advance
Yeah.. My computer didnt seem to recognise my phone either.. But it did get connected actually. There's some option deep inside control panel, where you can see what devices are attached to your computer. I will suggest you to go for a data wipe and install a fresh rom. Install via sideload, as you can access recovery, it shouldn't be a problem. Rom can be directly installed from pc to your phone, it case it doesnt have a rom, I believe. Google how to sideload using mfastboot

Or attach a pendrive with rom using USB otg cable

Fastboot flash the latest 5.1 factory firmware image for your phone - if available. Follow the tutorial linked in the first post. Note; it's very dangerous to flash incorrect firmware images.

Beginner flasher who may have screwed up and needs help :)

Hi there,
So I tried flashing my phone and unfortunately I seem to have wiped everything as I cannot even load anything from my local storage.
The phone does load in recovery mode and even fastboot.
How can I flash the phone without any ROMS currently on the phone?
Any help is appreciated!
Well here is what you need to do.
Download the latest fastboot ROM for OnePlus one from cyanogen os site from the support section.
Follow the fastbiot guide by Heisenberg to restore your device

There is no need in fastboot flashing the entire phone, as it seems that you have just wiped the entire phone from within recovery. Just download a rom of your choice (preferably the latest cm13 nightly) to your pc, then boot into recovery, attach phone via usb to pc, copy rom over to phone, flash rom, done.

Once booted into twrp recovery, go to "Mount" and make sure MTP is enabled.
If all else fails, follow this guide to fastboot flash your phone

Can only access fastboot and TWRP

Hello, I was trying to flash TWRP on my OPO and when I pressed restart, a message appeared suggesting me to also flash superSU and so I flashed it. That's it. I don't have access to the ROM, not even bootlooping. At this point how can I flash Pure Nexus? ADB Sideload won't work. It's stuck at "Starting ADB sideload feature. . .". Nothing will happen if I connect the phone to my PC and after a while it vibrates and I get "Failed" in red. Will an OTG cable solve my problem? I am willing to buy one tomorrow morning.
Clear all your partitions, by advanced wipe in TWRP.. Flash any rom.. For root always use SuperSu zip package and not the Twrp supersu prompt..

This happened to me also. Flash your new ROM using an OTG pendrive via TWRP. Hope this helps!
I used the OPO Tool to flash CM11S, flashed TWRP, flashed 7.0 N over TWRP, had an instant regret (unstable) and got back to CM13 again over TWRP.
Thanks!

No OS and no ADB access, how do i recover from here?

I do have TWRP installed, and tried to flash the xiaomi.EU rom which resulted in a bootloop. I thought that might be due to internal storage being encrypted so i formated it, removing everything. I then tried to push the rom via adb so I could flash it, but it turns out my computer doesn't count as being authenticated so I can't do that. Now I'm stuck with only twrp, no bootable OS, and no flashable Roms on my device. How can I recover from this?
Download a fastboot version of a stock rom and flash using Mi Flash.
