[Xiaomi Redmi Note 6 Pro Questions & Answers] crazybill:
Hi.

So I agreed to help a coworker who had a messed up Chinese version of the redmi note 6 pro and wanted to install a Xiaomi EU version instead. I told him I've done my share of flashing various phones, but have never tried to alter a Chinese model this way and there are no guarantees for success.

I was told this is a redmi note 6 pro. It looks exactly like that model when viewing google images for that model, with the camera, buttons, back fingerprint round circle and notch in the display. It is physically large, I measured it as 15.7cm high and about 7.6cm wide which pretty much fits the dimensuons from gsmarena.

In hindsight there may be something wrong here because it also has a sticker on the back saying 'm1804d2se' meaning it should really be the mi 6x, but it doesn't look like that phone at all! The mi 6x looks like the mi A2, and has no notch in the display and is definitely smaller. In the other hand, it indeed doesn't have a micro SD card slot (only 2 nano SIM sized slots in a tiny tray), which is true for mi6x.

Another option would be the mi a2 lite aka redmi 6 pro which also has a notch, but is noticeably smaller so that's off the table.

In short, it seems I have here a redmi note 6 pro, with no sd card support and with a sticker with a serial that fits the mi 6x. Weird.

Anyway, I tried flashing TWRP and EU MIUI ROM for the note 6 pro (tulip) using these versions:

twrp-3.3.1-0-tulip.img

xiaomi.eu_multi_HMNote6Pro_V10.3.5.0.PEKMIXM_v10-9.zip

Here's what happend since I started working on his phone until it became a hard brick:

1. phone was unlocked, but the system was in Chinese and requested a password that the guy didn't know and was essentially stuck in the configuration part you get upon first botting a newly installed ROM.

2. I held volume-down + power and entered fastboot mode, and connected the phone to the PC. The phone was recognized by fastboot.

3. I tried flashing twrp-3.3.1-0-tulip.img by typing 'fastboot flash recovery twrp-3.3.1-0-tulip.img', but got an error message relating to the ARB.

4. I verified the ARB status by typing 'fastboot getvar anti' and the output was 4 (meaning ARB is active). To overcome this limitation I typed 'fastboot boot twrp-3.3.1-0-tulip.img' and it succesfully entered TWRP recovery.

5. The phone does not have an micro sd card slot (it only has 2 identical SIM slots, each for nano SIM. no way to insert a micro SD card at all, so I had to push the recovery image to the phone's internal memory using 'adb push twrp-3.3.1-0-tulip.img /sdcard'. The file was succesfully pushed and I flashed the recovery from within the tmeporarily loaded TWRP. I rebooted to recovery and it entered TWRP.

6. From within TWRP: I did a complete format of the phone (the option that requires to type 'yes') and the regular cache, dalvik clean.

7. I pushed the ROM file using 'adb push xiaomi.eu_multi_HMNote6Pro_V10.3.5.0.PEKMIXM_v10-9.zip /sdcard' and it was copied OK. I flashed this ROM and it completed the flashing without any errors.

8. I rebooted the phone and it failed to reboot and seems to be hard bricked. No screen, no LEDs, not even when connecting the wall charger. Completely dead.

9. I tried using an EDL deep flash cable (the one with the clickable button), connected it to the wall charger on one end and to the phone on the other - did nothing.

I googled for help, read other threads, and couldn't find any solution. I don't have any access to a mi center, have no authorized mi account and have no idea how can I fix this.

I will appreciate any help possible. Thanks!
