[Xiaomi Redmi Note 4 Questions & Answers] buczek0711:
Hello.

I've got a new phone in my hands, which is named Xiaomi Redmi Note 4X (Snapdragon one).

As always I've tried to unlock it because stock roms just sucks.

I wasn't able to unlock my phone with Mi Unlock after getting a positive answer to verification via request (stuck on 99%). I've later found here, that this could be caused by trying to unlock my phone on stock rom, updated to MIUI 9.1.2.5 (9. something, not sure about last digits). So I've learned few things, mostly on xda-dev, as well as my homegrown page about xiaomi phones (mostly from this link -> https://miuipolska.pl/forum/topic/9218-odblokowywanie-bootloadera-w-urządzeniach-xiaomi-poradnik/).

Since I cannot put phone in adb fastboot edl mode (it's being seen by pc and adb, after the command it just reset itself, instead of staying in edl mode), Mi Flash does not work in 2018 (not sure why they drop it), I've decided to use fastboot mode and miflash.

Problem is when I enter the program, plug in my phone in default fastboot mode and start the work, after 3-5 sec I get error 0xffffffff with an option "flash all".

My rom (newest version of rom, taken from this link -> http://en.miui.com/a-234.html) is unpacked twice (to version with "images" folder), I've set it on my C:/ drive in catalogs without any blank spaces between the letters (these things made by clicking space button).

My phone is successfully connected with my mi account (I'm using it since I've got Mi Band2, so it is not so fresh).

My MiCloud synchro is online and up to date. I cannot make verification of that account, however (I'm not a bloody Chinese and I just do not understand their letters and language), but when I checked my account on PC, I've got 100 points (max) for security.

My phone, mail address and phone number are all known to our Chinese friends.

Debugging USB is also not a problem since I've double checked all of that.

I also tick the option for changing bootloader or OEM (somewhere over there in dev options). I even get extra permissions for debugging, that requires triple clicking "ok", due to the danger of being tricked by some skilled hax0rz.

I even deleted my extra security unlocking (both fingerprint and X letter made from dots) to make sure fastboot unlocking will work (this could have been the case in some...cases, as mentioned here -> https://xdaforums.com/redmi-note-4/help/bootloader-unlocked-99-stuck-progress-t3651303).

What else could I do to make sure my phone will be finally unlocked and rooted? I cannot do it with a locked phone, I cannot install TWRP on a locked phone (which prevents from getting root access). To get an unlocked phone, I need to install custom rom. To get a custom rom I need to install it via fastboot. Since I cannot do so, I'm stuck (if I understand it correctly).

I've checked *.txt file in a main rom folder, it's said "mido", and given version is 8.1.2.5 from 25th of January 2018.

Thank You for any kind of help, I've tried to download it for the second time (somehow, the names of the archives are different, but I'm not sure if that could be the case).

Also, this information might be needed – my phone is Redmi Note 4X 4/64, so I cannot use rom for 3+32GB, which is listed there also.
