Error flashing ROM's since "semibrick/bootloop" - Xiaomi Poco X3 NFC Questions & Answers

Hey guys,
Few hours ago, I Installed Poco x3 Europe ROM in my Global Poco X3 (with XiaoMiTool V2), and didn't start, it was in Bootloop. (Still don't know if this was a problem or not, I don't know what happened me that)
I solved it with MiFlash and flashing the lastest global rom "surya_global_images_V12.0.7.0.QJGMIXM_20201221.0000.00_10.0_global"
Finally, MIUI loaded, I install the TWRP, tried to flash crDroid ROM and these error appeared:
Updating partition details...
Failed to mount '/system_root' (Invalid argument)
Failed to mount '/product' (No such file or director)
After that, I don't know what I did, but I restarted and I didn't have any OS, phone starts automatically in Fastboot mode.
Again, reinstall the lastest rom with MiFlash, installed MIUI again, installed TWRP again, and I tried to flash LineageOS ROM:
Updating partition details...
Failed to mount '/system_root' (Invalid argument)
Failed to mount '/product' (No such file or director)
I retried to install the LineageOS again after that, and some extrange messages like:
patching system image unconditionally
patching product image unconditionally
After that, I installed OpenGapps Pico, and received Error 20. (I tried rebooting to TWRP again and flashing gapps again and same error)
Finally I made a reboot system, and LineageOS started, but without Gapps installed.
As you can see, I am newbie in the ROM world, I don't even know when to do wipe's (dalvik, cache, system) and format data, if before or after flashing ROM's, but yesterday, I installed ResurrectionRemix, ArrowOS, WaveOS and Pixel Experience ROM's without any problem.
What can I do?
Sorry you all for my bad english.
Best regards.

Since this happened to me, everytime I want to flash a clean ROM (European or Global) through XiaoMiTool V2, phone never work and start bootlooping in first screen (POCO in yellow) and I don't know why. I used XiaoMiTool V2 before and worked well.

Nobody know's what happening with my phone? My system_root and product partitions are broke? I need to change my rom, I don't like Miui haha

Small update.
I was using TWRP 3.4.0-15 (I think it's the lastest available)
Yesterday I installed OrangeFox R11.0_6 recovery, I flashed crDroid.zip ROM, apparently no problems with /system_root or /product:
patching system image unconditionally
patching product image unconditionally
After few seconds, error appear:
Failed to mount /vendor (Invalid argument)
After that (if my memory doesn't fail), I reboot in recovery, flashed NikGapps, and same error:
Failed to mount /vendor (Invalid argument)
I wiped cache, dalvik cache and format data, reboot system and crDroid started and I had Gapps installed, so maybe /vendor error is not serious, apparently everything works OK.

I flashed fw+vendor to flash another rom, and when I flash fw+vendor, I got error:
Failed to mount /vendor (Invalid argument)
After flash a new ROM.zip, I got error:
Failed to mount /vendor (Invalid argument)
After flashing gapps, I got error:
Failed to mount /vendor (Invalid argument)
Finally, I format data, and I got error:
Failed to mount /vendor (Invalid argument)
What the **** is /vendor and why happen this? xD

Vendor is specific to the device provided by the "vendor", i.e. usually the manufacturer (including customizations) – while System is the "Android base". If you upgrade a MIUI Rom with vendor deleted you're going to brick your device.
I think you need to do a full manual reinstall but I havent rooted my Poco. Maybe you wiped vendor when installing the custom rom... It advised to only wipe system and data

Do a NXT-L29 TWRP backup will resolve the issue ??

You have to wipe /data. Then you don't have this issue. To wipe /data you have to write "yed" on the prompt

You can try to go back to stock rom with the rayglobes tool. Select "unbrick" section. It will flash all partitions to stock.

Mutlirom Recovery Update---->Bootloop

Hello all
I just updated the multirom recovery after a year of successfully using it with 4 different roms, which 1 of them is ubuntu and now am stuck in a bootloop.
Whatever rom I try to boot it kicks me back to the rom selection screen. It must be something wrong with multirom recovery because even when I select to boot into bootloader or even Shutdown the phone from the multirom menu it just bootloops to the same screen again.
I'd really appreciate any kind of help you can give, it's extremely important I don't lose my roms. I want to save the phone as is.
Any ideas? Would really appreciate it.
-Regards.
I can't install any version of Multirom through twrp recovery. It always gives me error 7.
I also can't install a new rom. It says "Failed to create rom folder(Read only file system)".
I flash the AK kernel succesfully but at the end it gives me these errors:
E: Unable to mount '/data'
Failed to mount /data partition!
Updating partition details...
E: Unable to mount '/data'
...done
E: Unable to mount storage

Is there something rom with my file system?
Please, any idea would be really appreciated.

POCO X3 NFC TWRP Issue (Failed to mount /system_root)

I flashed unofficial TWRP Recovery V3.4-15 as published on XDA. I first took a backup of existing data in TWRP. Then when I tried to Wipe or format it gave me the error:
Failed to mount /system_root (invalid argument)
This message keeps apperaing when tried to flash ROM and even try to go back to my backup. Can anyone please help me how to solve this issue???
UPDATE: Somehow I figured it is related to Mount issue. I went to Mount and unchecked read only mode. Now I am getting two erroes. Ye it sucks more.

Phone no longer has OS and having trouble installing custom rom

Hey guys, hoping someone can save me from having to buy a new phone. I either need to fix it quickly or replace it quickly cause my job depends on having one.
I have a Moto 9 g plus.
I wanted to root my phone for a long time and today I decided to try since the Android 11 update ****ed up the camera on my phone anyway.
I followed this guide here
Root Motorola Moto G9 Plus Android 10 using TWRP and Install Magisk
When you have Stock Android on your mobile, You are almost free from bloatware apps. Even if your manufacturer put some apps, You can get rid of them in
www.androidinfotech.com
Everything seemed to be going well except that I couldn't get magisk to install, I kept getting errors in twrp.
I ended up installing the apk for magisk and used it to modify the boot file. I installed the image in twrp and on reboot, it went into a boot loop. I could go back to trwp and after swiping to factory reset, it broke the loop when I restart the phone. The problem is that now it just goes straight to the menu that you normally need to press and hold down and power to go to. I never did get to confirm if my phone was successfully rooted or not, I'm guessing no, and that that is the main problem now, as the phone won't boot up to where I can use apps, and if it isn't rooted, from what I understand, I can't install another rom?
Also, whenever I'm finished with twrp, when I press to reset it says something like "Phone no longer has OS, are you sure you want to reboot?". I read it is from wiping the data or factory reset, but I didn't actually wipe any internal memory, I can still view all files on it and on my sd card.
Maybe you guys can confirm my suspicions that I just ****ed up my phone for good or not.
This is what the error says when I attempted to install a rom, I tried with lineage and arrowos and I don't believe the problem is with the roms.

Thanks to anyone to offers any suggestions, this is my first time attempting this, so don't assume I know anything, I just step by step tutorials and usually don't have problems like this.
