Stuck in black screen, can't boot into fastboot mode - Xiaomi Mi A1 Questions & Answers

I got my Mi A1 today and it came with Android 7 installed, so I decided to install LOS. I unlocked the bootloader and then I booted into TWRP using fastboot (I didn't flash it), it gave that "system is read-only" warning. I tried to reboot to system without doing anything and it was stuck in a boot loop. Then I booted into TWRP again and flashed LOS sucessfully. When I tried to flash gapps, however, it failed claiming I was still running Android 7. I rebooted and it booted sucessfully into LOS, but that was the last time the phone ever booted. Now it shows the unlocked bootloader message and then gets stuck in a blinking black screen. I can't even boot into recovery or fastboot anymore.

It seems you will have to flash stock ROM using Mi Flash (no idea how to use it so search it) and, once is done, flash LOS again.

I somehow managed to get to fastboot and then I used MiFlash to flash the stock rom. I'm back to the bootloop, which is an improvement, because at least I can consistently get into recovery and fastboot.
The phone got stuck in that black screen after I tried to flash LOS, should I actually do it again?
EDIT: I flashed the stock rom a second time and it's working again. I don't know why, but I'll take it.

Update to stock Pie before trying to reinstall LOS again. Hope this time works.

You should install 1.0.8.0firmware first before install 9 ROM!?

Nexus won't boot properly after flash

Hey guys, I flashed SmoothRom via that app goo.im, and when I did it, it said that I needed a compatible recovery, so I flashed the one that it recomended. Well I flashed the rom, and now my Tablet won't boot properly. I can get it to fastboot, but even when I try to flash a recovery from fastboot, it gets stuck at the boot screen (Yes my bootloader is unlocked). I've been trying to use the Nexus 7 toolkit to flash the recovery,and it is saying that it is flashing successfully, but I still cannot boot into recovery. Any ideas? I know I'm not totally bricked cause I can still get into fastboot, I just need recovery to work so that I can flash a new rom and fix this issue!
Fixed it! Just flashed the stock recovery, wen't back into fastboot and flashed CWM. Mod's you can delete this thread now

Stuck at room boot animation, no recovery mode

I have installed Unofficial CM 13 successfully, but I forgot to root the device, so I go back and flash supersu file and reboot - I think I flashed wrong version for marshmallow. now phone stuck at cm boot animation, I have no recovery, only has access to download mode. I also have no access to phone through adb or fastboot.
I was in the similar situation before, where I was stuck at lg logo, and fix it by flashing stock rom (now I cannot find that thread), but now it tries to boot the rom, seems like a different situation.
What should I do?
lg g2 stuck on lg logo

Help in flashing custom roms

I've unlocked the bootloader using the official asus unlocking app.
Upon checking fastboot oem device-info it says that my device is unlocked.
I had flashed twrp 3.0.24 using fastboot and rooted it but when i try to flash cm13 (downloaded fom official cm site), it gives error 7.
So, I had removed asserts from updater-scripts and tried to flash which was successful but it did not but and got stuck at fastboot mode
I had anandroid backup which helped me reviving and after that i eve n tried ressurection remix, which too fell me in the same problems..at first i got error 7 and after removing, it didnt boot..
I even flashed cyanogen recovery but after flashing, when i try to boot into recovery, it gets stuck at the fastboot mode ... though it booted normally, but it didnt boot into recovery mode.. so i again flashed twrp which booted properly though..

After flashing TWRP for the first time (especially TWRP 3.2.3 by SagarMakhar https://androidfilehost.com/?fid=3700668719832241089) you have to wait for nearly 5 min for first decryption to fail.
Afterwards it works as usual.
You will get TWRP logo on screen and have to wait until you get into MENU.
If it is a bootloop you will not bootloop into TWRP but on system.
Hope this helps

Thanks for the reply, but u didn't get my problem, this is not the first time I'm flashing twrp, this happened after I changed from one rom to another, twrp was working fine until now.
And the problem is, if I try to boot into twrp it shows the twrp logo then immediately a black screen comes up then the twrp logo again and so on indefinitely.
I've tried flashing twrp again through fastboot, it succeeds but same thing happens when I boot into twrp again. I've tried different twrp versions as well.
Directly booting from fastboot doesn't work and spits out an error. (FAILED remote: unknown command)
Do u suggest I try to go back to stock rom using the 247 fastboot firmware?

Fastboot flash to 247 will resolve the issue if it was caused due to any ROM.
May be some partition got formatted.

Ok I have a few doubts regarding going back to stock.
This is the guide that I'm supposed to follow right, the one in the OP by you? https://forum.xda-developers.com/as...ow-to/guide-revert-to-stock-rom-lock-t3798420
Is it alright if I am in a custom rom at the moment, can i still flash the fastboot firmware?
And is it safe for me to do it right now with twrp still kinda present?
Thank You so much for your help, really appreciate it
Edit: Ok just realized your post answers all of my questions but thanks anyway

-PLEASE HELP- UNABLE TO FLASH TWRP OR ROOT

Hello
Sorry for my bad english
a few months ago, i decided to flash my first custom rom (One UI rom) and it worked fine
then i was testing a lot of other roms too until i tried lineage os 20
when i flashed lineage os 20, i decided to try another rom but i was stuck on the twrp logo screen. i tried methods of fixing it but none of them worked.
after trying a method of flashing twrp once again, it failed and i got stuck in a reboot loop and could only boot into download mode. so i booted into download mode and flashed a stock rom.
everything was working fine again until i wanted to try another custom rom. At first whenever i would flash twrp, they would always fail. but later i found the cause of that and fixed it. then, flashing twrp would always pass but my device would get stuck on a reboot loop once again and i had to flash stock rom again.
i tried rooting using auto root but it would show me a verification failed error and i had to reset my device. so now im stuck on a device which cannot flash twrp, nor can it be rooted. its been 1 month and i could not find a viable solution so any help would be extremely appreciated.
You have to just reflash your fastboot rom with fastboot mode unzip it and double click on flash_all.bat file or something like that
it is a samsung, there is no fastboot mode
