Redmi Note 4X bootloop - Xiaomi Redmi Note 4 Questions & Answers

Welcome, I have Xiaomi Redmi Note 4X Global. I've had my new phone for a week. Right after the first boot I updated it to MIUI 9, unlocked bootloader, installed root, exposed etc.
Everything was working fine without any problems. Today I wanted to try something new and I installed Resurrection Remix OS. Before it I took a backup with TWRP (through PC, I got backup.ab)
I was using the new rom for a few hours but then I realised that I preferred MIUI and I restored previously made backup (backup.ab). And here came the problems.
The device after restore came into a bootloop. Xiaomi logo appeared for a few seconds, then a single vibration, restart and the same again. After this I flashed (with MiFlash) a stock
firmware for my device from [url]http://en.miui.com/a-234.html[/URL] (the right one for sure) "Redmi Note 4X Latest Global Stable Version Fastboot"
Flashing through PC has always helped to unbrick devices but I don't know why in this case it didn't.
I can still enter fastboot mode and recovery so I flashed TWRP, made a full wipe with it, and installed:
-Resurrection Remix OS
-LineageOS
-recovery zip versions of MIUI (many versions)
After installing each of those I get the same result, a bootloop. I spent rhe last hours of trying everything in different combinations and looking for any information.
Can anyone help me with this problem, has anyone even faced something like that?

Well, try this method :
Download firmware.zip, Amy custom Rom, and Gapps.
Next, boot to TWRP and wipe (advanced wipe ~) wipe everything except internal storage or SD card.
Flash firmware.zip, followed by Rom and Gapps, Reboot.

If I recall right, I've had this same issue. So, do one thing download Recovery flashable Xiaomi stock miui Rom or download Xiaomi EU Rom, then as I said earlier boot to TWRP once again, wipe, advanced wipe > wipe everything > install stock miui > lazyflasher.zip >reboot. Lemme know how it goes.
LazyFlasher : https://www.androidfilehost.com/?fid=529152257862700328
Flash lazyflasher.zip if you flash any miui Roms other than Xiaomi eu Rom before reboot.

I did exactly as you said, wiped everything, installed stock MIUI recovery version and lazyflasher.
No errors appeared but when I wanted to reboot my phone after installation I got an information that
no OS was installed.
I swiped right anyway to reboot and here comes the bootloop again. :/
EDIT: Tried with both stable and developer versions
-miui_HMNote4XGlobal_V9.0.5.0.NCFMIEI_d6176de291_7.0.zip
-miui_HMNote4XGlobal_7.12.21_9a89725dfc_7.0.zip

I also get those errors (?) while mounting during installation.
It's red themed because I was currently using Red Wolf Recovery but I get the same results when I use cofface TWRP or original TWRP

Holy crAp. Alright, I'm no expert with fastboot Rom or so, did you try flashing fastboot Rom? Give it a go... :c
BTW, there's a device team guide on mi forum about flashing Redmi Note 4/4x : http://en.miui.com/thread-482304-1-1.html

Did you just "wipe" everything, or did you "format data" also? I suggest that you format the data partition (there is a button for this under the "Wipe" menu in TWRP), and then install your ROM again.
You need to install lazyflasher only once - after installing a custom Recovery. - but -you must do this each time you change your custom Recovery (but only do it once) - otherwise, MIUI will not boot correctly. Note that you do not need lazyflasher if you are using a custom ROM (eg, AOSP, etc).

I had a similar issue after installing Resurrection Remix then trying to go back to MIUI.
I used MiFlash to install a stable rom but got a boot loop after reboot.
In the end I flashed a stable rom using Miflash using the 'clean all' option. Then without rebooting I installed TWRP via adb. Booted straight into TWRP and installed the no_verify .zip. Then used TWRP to restore a nandroid backup I had on an OTG USB drive. It then booted without bootlooping. So I used Miflash to reinstall the stable rom with 'clean all' option again. Rebooted ok like a brand new phone.

I join the cause
Hi, I join the cause @ Pr3z3s. I have tried everything. And I still have the same problem. the only thing that occurs to me is that someone gives us a backup, please do upload it, and we try to restore it in our mobile.

---

can you tell me what kind of unable to mount or unmount errors you encounter when flashing? my guess is that some of your partition is corrupted

I did both many times. When it comes to lazyflasher I did flash it but didn't help.

Those on the second screen I put in the previous page of this thread, like unmount of /firmware failed; no such volume
EDIT: I just tried restoring .ab backup through adb and an error while restoring EFS partition occurred so I flashed a stable ROM with MiFlash and took a backup of EFS partition.
Then I restored my backup again and after an error with EFS I restored it from a backup I had just taken - no errors appeared. Then I flashed lazyflasher and rebooted and still I'm in a bootloop.

here you go, my /firmware and /efs nandroid backup, seems like you have some trouble with efs as well so i included it , and to clarify things, my device is redmi note 4x MIDO 3gb/32gb edition running on cardinal aosp 5.1.1 12/10 with global miui v9.0.3.0 firmware, dont restore backup if you have a different edition because i don't know what will happen to your device . https://drive.google.com/open?id=1a8-tjbrkV8vNKaWcBsClbVlvBADinXSB
EDIT : I'm not confident that this will fix your device because it seems that either your /firmware is corrupted, or somehow disappeared .. do tell your results though , dont blame me if it becomes a hard brick ><

Thank you for sharing your backup but I get errors while restoring it.
EDIT: All partitions seem to be present when I go to "Backup" section. What is more, I got the same error with EFS when I was trying to restore my orignal backup.

i removed my link because it seems that efs might contain device sensitive info like my IMEI and mac addresses, so dont restore my efs backup,it seemed to ended up spitting an error though. anyways, it seems that you are on TWRP , i backup-ed using redwolf, so that might result in the error, and yeah, dont restore my efs partition next try
