HELP!!!! I have my phone stuck in bootloop - Xiaomi Redmi 4X Questions & Answers

I was trying to upgrade TWRP of my Redmi 4X from 3.0.2 to 3.3 and that new TWRP showed my internal storage as 0MB and no contents, after checking my log, it said "failed to mount internal storage". So I rebooted back to MIUI to flash older one TWRP 3.0.2 via Offocial TWRP app. But doing so has made my phone stuck at boot screen showing Mi Logo and unlocked at bottom. If I try to enter recovery same happens, if I try to go to fastboot, it justs shows Fastboot rabbit, but nothing happens next. What to do, please help. When I try to flash same TWRP 3.0.2 using PC CMD, it doesn't detects any devices, both using adb and fastboot commands, Please help.

Flash any MIUI version of your choice via Mi flash tools(don't lock bootloader and don't clean flash) and then flash recovery. i can't say anything about your data in phone if it will retained or not, it should but i can't be sure.

HELP - Cant boot after updates

Hi, I have a MI5 with chinese ROM...
I've unlocked the bootloader, flashed TWRP rocovery and rooted it.
Problem start when i updated using the built in apps. And now i am in this MI logo screen with the 2 dots flashing... 20-30minutes.
I've tried wiping to factory reset, wipe dalvik > reboot ... no go
I've tried miflash the fastboot rom and Miflash showed "The operation completed successfully." > auto reboot ... now is 25 minutes into the boot.... still no go
I'm panicking now.... Please help
I forgot to mention, the file system is decrypted.
Now i cant go into twrp. there's a screen showing a phone with cable. I still can go fastboot though
Help please
Just to share, I'm able to get it boot again.
Instead of using "Flash All except Storage" in Miflash, I selected "Flash All".
After completion of the flashing, it took around 7-8 minutes for the first boot before system GUI came on.
I think it may be due to SuperSU that i have installed earlier.
But now i cannot boot into recovery, should i fastboot flash TWRP again or revert to stock recovery? Please help on how to do it.
Can i install SuperSU by using fastboot?
it makes more sense now.
After flashing of developer rom, the phone is encrypted again and recovery is reverted to stock which i think will only works with updater.

NEM L-21 Bootloop

After unlocking my bootloader on my NEM L-21 I installed TWRP too, it all worked fine and well and then I decided to flash a CM13 ROM, before doing that I wiped my cache and userdata, I tried flashing it but then it threw me errors about not being able to mount /cust, I decided to restart it and leave it for later but now after restarting I can't boot into my system.
It restarts by itself if I try booting into the system, booting into the erecovery is useless since it cant find a firmware for my phone to download, and whenever I try booting into TWRP it gets stuck on a screen with "Your device is booting now...".
Any ideas on how to access TWRP or possibly flash the stock rom? Fastboot refuses to do it.

Download the official firmware. Extract it using "huawei update extractor". There u will find recovery. Put ur phone in bootloader mode, by volume - & power button. Flash the recovery. Put the dload folder in ur sdcard. Then by the three button procedure, flash it.

Have you tried Erecovery to restore stock?
On the bootloader unlocked warning screen press and hold volume+ for 3 secs.
Needs to use WiFi.
Try yo reflash twrp in fastboot mode. The command is fastboot flash recovery_ramdisdisk twrp. Img
Before you have to put twrp. img in the adb folder
I'm experiencing the same problem after trying to root my h9l through twrp the mistake I made is that I flashed the image in a wrong partition.
I can only access a fastboot mode with frp and phone unlocked, it cannot even display a charging screen. Once plugged it keeps on rebooting and hangs on error screen,
I have tried to flash kernel,ramdisk, recover_ramdisk and system images all on their respective partition, the flashing went well, but the phone didn't respond.
I've tried to flash boot.IMG (some one posted for h9l,) into Boot partition, but it revealed an error.
Any one please help what should I do to brings by device back to lite

Can't mount any partition to wipe with twrp 3.3.0-0 data/system/cache/dalvik

I come from stock miui 10.0.2.0 unlocked bootloader and debug feature on, I flash the recovery via fastboot, then, I boot trough fastboot to to make recovery persistent, then when I reboot the phone it get stuck at miui logo, but I can enter in to the recovery I flashed before.
The problem apears when I try to wipe any partition, it says that can't mount any of them so is imposible to flash anything.
I can flash trough MiFlash tool to get back to stable MIUI without any trouble.
I readed many post about this problem and as far i can figure, its a SElinux or crypto problem.
Any idea of how can I solve this?.
Regards.

Pease help me unbrick asus memopad me170c (K017)

my tablet (asus me170c) was hard bricked for a long time and only usb logo showed up. using this amazing guide and using xftk tools I managed to make droidboot available but I can't boot into recovery or system. fastboot detects the device but adb doesn't. I read all similar xda treaths and downloaded about 5 or 6 roms (including raw rom) and started trying the following(but none worked:crying: ):
1-first i tried to boot into recovery and flash latest rom but sadly the tablet won't boot into recovey and SD update is not available in droidboot.
2-then i downloaded ASUS flash tool to flash raw rom but even though all drivers are installed and i can see my tablet in device manager phone flash tool doesn't detect the device :crying:
3-since there is no custom recovery for this specific model, i tried flashing me176cx unofficial twrp by fastboot: fastboot flash recovery twrp.img but it didn't flash recovey with sign_key ROS error (but boot.img and fastboot.img were flashed successfully. and i also tried flashing the raw frameware's system.img with fastboot and it was flashed successfully but nothing changed and the device is still stuck on intel logo.
4-as my last chance, I tried booting into temporary tethered twrp and it booted! but the touch screen didn't work. then I booted temporary cwm but it can't flash any of frameware zip files on external sd card even though it detects them! with erorr closed:0. and It can't load internal storage. there was also an adb sideload option in cwm and after enabling it adb finally detected device but adb sideload zip file failded with the same closed:0 error
5-I also tried Intel flash tool and it detects the device but says the firmware xml file is invalid both stock rom and raw rom have the same error.
I thought making it into fastboot will make reviving my tablet easy but it didn't.
please help, I don't know what else to do i need this tablet for reading books.
