Bootloader/Fastboot Problem Please Help! - OnePlus 3 Questions & Answers

Hi All
I would appreciate a little bit of thought/help on my recent problem with my OP3.
I was running Stock Oxygen 3.2.4 rooted (system-less)
I wanted to go back to stock. hence I flashed stock recovery and sideloaded Factory Zip.
Now I wanted to reflash twrp recovery just to keep it handy just in case I need to go back to rooted, but to my surprise when I adb reboot bootloader or choose fastboot mode from the boot menu I get presented with a blank/black screen and fastboot doesn't get detected. The Notification led is switched on a white colour and nothing happens.
Again I would really appreciate if anyone can help me with this as I've been an android owner for the last 6 years and never had this problem.
Thanks All!!

Does the device boots OS ? or just it can't boot into fastboot mode or recovery? Can you please elaborate ?

Broken recovery?
Reflash your recovery in fastboot and try again

Soft bricked my M8: Best way to fix?

Greetings All,
So I did a very stupid move and kinda soft bricked my M8. I received my Lollipop update, restored my stock recovery, applied the update, rebooted phone, applied TWRP and flashed SuperSU. Once I booted back into phone I saw that I still had Xposed installed and bundled and the idiot that I am, ran the uninstaller. Now the phone boots up and after showing the white boot logo sits at a black screen.I can get into recovery mode so I am pretty sure that if I download a Lollipop custom ROM I can get booting again? Factory reset did not help and I did not do a nandroid either :/. I am still S-ON so I can't flash the RUU file :/.
Any assistance will be greatly appreciated.
Problem resolved. Please ignore this thread .

Need help to go back to MIUI

So I recently changed my Xiaomi Mi MIx 2 screen (the one before was broken) and I wss using LineageOS 16 with TWRP.
The problem is that, after I changed the screen, I could not boot back to LineageOS because I was stuck in a grey screen (after booting the phone I am able to see the Mi logo and the LineageOS loading animation, but after that nothing).
I tried to do a Wipe from the TWRP, but whenever I try to open the recovery I get stuck again with a grey logo... (and in the recovery it does not even shows the TWRP logo, just straight the grey screen). I am still able, however, to go in Fastboot mode and I do have an unlocked bootloader
So my question was... does anyone encounteredd the same problem? And does anyone know how to fix it?
Can I perhaps just use the Mi Flash tool from fastboot to go back to stock MIUI without first wiping from TWRP things like Dalvik cache, cache, System ecc... or would this method fail/brick my phone?
Thank you a lot to anyone that would spend time to help me (and sorry for my bad English, I am trying to improve it).
Have a nice day!
The mi mix2s rewrites a new recovery after every boot, so to get TWRP to work you have to flash it from fastboot every single time. So the next time you boot, reflash TWRP, then you can boot into recovery 1 time and flash the rom of your choice
Hi Guys,
Recently i'm changed my broken display of Mix 2 after that when i'm entering to recovery it showing a gray screen also the phone is detecting on PC.
some TWRP worked but after flashing custom ROM same as showing gray screen after finished boot also doing second try the touch not working on TWRP.
Now i'm using Global version of MIUI11, when flashing custom TWRP via FASTBOOT MODE its booting up but after that restarting the phone revert back to the stock Recovery. Earlier i'm used the final version of MIUI12 Weekly EU ROM
Guys if you know any workaround for this please help me to get rid out of this
Thanks in Advance

Unlocked bootloader - boot loop after trying to put stock firmware back on

My telephone keeps booting to fastboot after trying to update TWRP.
I am trying to restore the original ROM (apollo_eea_global_images_V12.5.12.0.RJDEUXM_20220208.0000.00_11.0_eea) and I can get the rom installed through fastboot but the phone enters a boot loop cycle. It starts up, vibrates shortly then reboots.
If i press volume up it goes into the original recovery menu. I have tried clearing everything and even entering safe mode but the phone will not boot.
Am i screwed?
Thanks in advance.
I installed the Pixel Experience recovery and side-loaded the zip and at least have a working OS.
I must be doing something wrong with the stock mi10t
Now i sided the miui zip and its working agian. I think i have misunderstood the procedure. I thought you only need to install the rom with flashboot and that was it.

Phone could only boot to fastboot (this is meant to help others)

(I found a way to fix it, but im not sure what could have caused it) My phone suddenly turned off while i was using it normally, and when i turn it on, it goes to fastboot mode, ONLY on fastboot mode. TWRP is still accessible, but i couldn't boot my phone back to normal.. I checked the volume buttons to see if they were stuck, but they weren't.. so i'm here to say what you should do to recover your phone:
You'!l have to flash stock rom in your phone (latest version is reccommended), but this will remove TWRP, so you'll have to flash again. Bootloader will remain unlocked after flashing stock rom.
If you guys can help me know what could've caused this, it would be very appreciated (•‿•)
