I tried to follow the instructions given in post 170 but after step 5 the phone wont boot. Stuck at the MI logo for over 30 minutes. The bootloader is also blocked now when checking in fastboot.

I updated my Mi-4c from MIUI 8 (6.12.22) to MIUI 9.1 (7.12.21) and my bootloader kept unlocked. NO problems at all.
Can you tell me what you did exactly? I tried to follow the instructions given in post 170, but they didnt't work for me.
You need to go back to official firmware using xiaomi miflash tool.
Update to 6.12.22.
Update to 7.2.9.
Apply for bootloader unlock(the official way).
Then try new roms.
Once you officially unlock the bootloader it should not be re-locked
LE: I also had some issues with updates, but the bootloader unlock was the key in the end. you can follow my replies in this thread.

Thanks, so the important step I was missing seems to be the official way of unlocking the bootloader. I also tried flashing from 7.2.9 to miui 9 (7.9.2) but that didn't work so it was probably the bootloader.
I managed to install the latest miui. The problem was that after going to 7.2.9 the bootloader gets locked. I unlocked the bootloader using the official tool after getting permission and then there were no problems in installing other roms. I also used the twrp 3.1.1.0 as it works on both android 5 and 7. Thanks for the help guys!

Same happened to me when I updated from Android 5 to Android 7 for the first time. Like you, I got my bootloader locked and had to unlock the official way. (Also had some trouble with the firmware as described here:
https://xiaomi.eu/community/threads/mi4c-android-5-1-1-to-7-0.40827/page-3#post-381538
Even though I finally managed to install that first version of MIUI 9, I went back to Android 5, cause I didn't quite like that first MIUI 9 I tried, (7.9.14).
When I updated to this version MIUI 9.1 (7.12.21) this time my bootloader didn't get locked. Also did it with TWRP 3.1.1-0 (the only one didn't give me any trouble). And back to OTA updates again! (Jesus! I don't remember the last time used to get OTA updates)
Hi all! I need help before i brick my device.
I want to flash MIUI 9.
i have xiaomi mi4c:
android 5.1.1 LMY47V
miui - smiui 8 by sebsch1991- based on 6.7.14
TWRP 3.1.1.0

Im not very intouch with flashing
I can't update TWRP to 3.1.1.1 / phone boot loop reboots to MI.COM logo .After sevral reboots it can boot Miui and TWRP disappears/
I can put back TWRP 3.1.1.0 by "official TWRP app"
What should i do to flash MiUi 9?
Thanks

It's not very clear what you did. Try to be more specific.
If you flashed 3.1.1.1 on Lollipop rom, it might not be compatible - check previous posts/pages for a version that supports both Lollipop and Nougat.
To flash MiUI9 check also previous posts/pages everything is explained there.
I.e.: https://xiaomi.eu/community/threads/mi4c-android-5-1-1-to-7-0.40827/page-8#post-401725

Hello!
I have the same problem as you and I do not know how to solve it. I can only enter fastboot mode and I can not unlock the bootloader even if I have permissions.
Have you found the solution ?.
If you have any ideas, it would be very helpful.
Thank you

From latest beta xiaomi.eu 6.12.22 I update to first android 7 xiaomi.eu 7.2.9 the bootloader locked. Now no twrp. Mi unlock stuck on 99% current account cannot unlock this device. I'm pretty sure I'm with the right account... Everything is prepared in pc, in mi cloud etc. I read I can unlock even if xiaomi.eu is the rom, is this right or I must install china beta rom??? What if with latest china beta locks EDL and I can not return to 5.1??? if something goes wrong

Of course is the same account. USB debugging, enable OEM unlock... Everything is done. Except there is no Mi unlock status to pair device and account.

For those that cannot unlock bootloader offcial way (user cannot unlock this device error message):
same problem as @Kockata - This user cannot unlock this device for 2 weeks now. I was able to go to miui9 though but max I can go is 7.9.14 - 7.9.21 gives me bootloop.
Those are steps to get to 7.9.14 xiaomi.eu
xiaomi.eu
1. Flash 5.1 android with unlocked bootloader
5.12.17 -> miFlash - libra_images_5.12.17_20151126.0000.5_5.1_cn -- (https: // androidfilehost.com/?fid=24438995911972289)
- go to fastboot
- use MiFlash to install 5.12.17
if there is partition not allowed error just run in cmd as administrator
fastboot oem edl
when flashing finishes restart phone and wait for phone to start to system than restart to fastboot
check if bootloader is unlocked
fastboot oem device-info
2. If it is unlocked install this twrp - found it in this thread (thanks @slimozis) it allows you to flash android 5 and 7 + works even after you get your bootloader locked. (https : // androidfilehost.com/?fid=673791459329071444)
fastboot flash recovery twrp-20180106-1033.img
fastboot boot twrp-20180106-1033.img
3. When in TWRP Copy
xiaomi.eu_multi_MI4c_7.2.9_v8-7.0.zip
xiaomi.eu_multi_MI4c_7.9.14_v9-7.0.zip
to internal Storage
now install from TWRP 7.2.9 - than wipe davik/cache (not sure if needed but I do it every time)
reboot to system
when phone starts go to update app and reboot to recovery
now install 7.9.14 - wipe davik/cache
reboot to system
This is where I stopped. trying to install 7.9.21+ always ends up in bootloop. Anyone any ideas how to go further? Have locked bootloader and working TWRP 3.1.1
T.
PS. @mnikolce I installed all sort of fastboot dev roms and didn't get edl mode locked.
