[SOLVED] OnePlus 3T A3010 - Stuck in Bootloop - OnePlus 3T Questions & Answers

I unlocked bootloader and flashed latest TWRP to my recovery partition and rebooted to recovery to wipe all data.
Then the "your phone has been unlocked" message screen where you have to wait for 5 sec kept appearing every time I restarted so I wanted to remove it.
That's why, I locked the bootloader but as soon as I did that, my phone got stuck in a bootloop, I can't even go into recovery mode but I can go to bootloader but I am unable to unlock it or wipe data via ADB now.

Soft-Bricked Moto X XT1052

I was flashing Xposed 5.1.1 onto my CM12.1 in TWRP. It didn't have any errors and I rebooted. Half an hour later my phone is still trying to boot into CM. I restarted into bootloader mode and tried recovery. Recovery starts booting and shows the teamwin sign. Then it restarts into CM. I tried reflashing TWRP and it succeeded but TWRP still restarts my phone.
tl;dr: my phone boots into bootloader; fastboot working twrp broken.
Any help would be much appreciated

HTC One m7wls Unknown boot up Issue

I have an HTC One m7 sprint and recently I encountered something usual in the sense that, my battery run out and I placed it on charge while the phone is off. After awhile I try to boot up the device but it takes forever to boot up. I have installed a cm-13 rom on the device which was very stable. I have twrp 3.1.1 installed on the device. my device is S-OFF and bootloader unlocked. For 3 days now I haven't been able to boot up the device to ROM because its always stuck at the cyanogen logo. Whenever i try to boot to recovery, the twrp logo comes and it takes forever to boot into the recovery menu. To be precise, 10-20 mins to boot to recovery menu. Now what buffles me the most is that, I can't format my data because anytime it starts to formatting process starts I get 2 kinds of red line errors:
E: failed to write /dev/block/mmcblk0p19: I/O error
Error opening: '/cache/recovery/ .version' (Read-only file system)
I haven't been able to Restore my backup because of the error above,
I haven't able to copy files to the internal storage
I haven't been able do anythings significant at the recovery
I can't install new ROM
here are some steps I have taken so far to help fix the problem but to no avail
I have flashed older versions of the custom recovery through fastboot but whenever I boot to the Recovery I still see the twrp 3.1.1 i flashed before the problem happened. Even though my command.exe tells me that the flash was successful but it doesn't overwrite the twrp 3.1.1
I have fastboot erased cache but nothing happened
I have tried to return the device to stock by RUU method but whenever I fastboot oem rebootRUU, the device powers off, reboots to white HTC logo attempts to boot phone instead of going into RUU mode.
I have a hunch that somewhat my internal storage is corrupted and is probably causing these problems but I don't know how to go round it.
Any help will be gratefully appreciated.

Reboot bricked the phone

So I have a K20 Pro from China that came with bootloader unlocked and a 'global rom'. I installed TWRP 3.3.1-13 and installed Xiaomi.EU and worked fine for some days. Today I rebooted to recovery from the power menu and in TWRP it asked for a password and I entered it then it started decrypting data and I just rebooted system and it's now stuck in a bootloop in Redmi logo and after a while it just reboots back to TWRP and asks for the password. How can I fix this?
Thanks in advance
I tried reinstalling XiaomiEU ROM but now it says there's no OS installed. It gets stuck in the Powered by Android screen and then after a while goes back to TWRP. What should I do?

Try formatting data (where you type yes)

Device suddenly in bootloop [merlin]

Hello everyone, my phone (Redmi Note 9 merlin) has started bootlooping. It can boot to fastboot, but is unable to boot to recovery (either through fastboot reboot recovery or Vol + during boot). I have tried using SP Flash Tool using the hard brick tutorial and it still bootloops even though all steps proceed normally. I have tried to flash both old and new versions of MIUI, and all of them stlil do not work.
My bootloader is still locked so I am unable to use fastboot or other tools (like MiFlashBoot) on it.
Trying to unlock it from Mi Unlock gives me an error (1004). It seems to be due to the SIM card not being the same but I have not touched the SIM card since I got the phone.
In the past I have used MiPhoneAssistant to restore it as I could access recovery mode, but now even recovery mode is out of my reach.
What should I do now?
Thanks for your time.
Do you know what could cause the boot looping? The most common one is after installing a new version of MIUI.
I'm not sure how it happened, but if it is caused by a MIUI update, how would I go about fixing it?
If it has a locked bootloader and it's still in a warranty. Visit the store where you bought it from and claim the phone has stopped working and started bootlooping.
