Bootloop (stuck on 5G logo) after flashing Xiaomi.eu ROM

Dear fellow XDA-dev community members,

Xiaomi Mi 10 (umi), coming from original stock ROM, MIUI 11 GLOBAL version V11.0.2.0.QJBMIXM.

Bootloader unlocked official way via MiFlash Unlock 4.5.514.47.

Custom recovery TWRP 3.4.1b-0313 installed via XiaoMiTool V2.

Tested root by installing Magisk 20.3 via TWRP, no problem, then updating to Magisk 20.4 with the Magisk Manager 7.5.1.

The problems started when I tried to install Xiaomi.eu Custom ROM : xiaomi.eu_multi_MI10_V11.0.25.0.QJBCNXM_v11-10

Downloaded the Xiaomi.eu ROM to PC, then copied to the Download folder of the Phone.

Started phone in upload mode or TWRP. > Wipe > Swipe to Factory Reset + Format Data.

When formatting data I erase all folders in the phone, including the Xiaomi.eu ROM copied in the Download folder.

Some tutorials suggest to copy the Xiaomi.eu ROM from PC to phone after formatting the data, just by connecting the phone in TWRP to the PC, by going to > Mount and enabling MTP.

Tried this method but when I send the Xiaomi.eu ROM file to the phone the progress bas doesn’t move.

So I restarted the phone, without installing the Custom ROM, went through all the screens of initial phone configuration. Lost Magisk and root (but I supposed that it’s not mandatory to install Custom ROM). Copied again the Xiaomi.eu ROM zip file to the Download folder. Rebooted to TWRP. This time I just did Factory Reset but without Format Data. Then > Install to install the Xiaomi.eu new ROM. Cleared Dalvik Cache then reboot.

PROBLEM : bootloop. Stuck with the 5G logo forever, waited more than 30 min, no change.

Still have access to recovery TWRP and to bootloader mode. I suppose this is a soft brick?

I did > Wipe, Swipe to Factory Reset + Format Data, restarted… no change.

Copied this time the Xiaomi.eu ROM to a clean formatted (FAT32) USB drive. As shown in some tutorials, you can us an external USB drive via USB OTG to install the Custom ROM via TWRP.

Factory Reset + Format Data, then I installed again the same Xiaomi.eu ROM from the external USB. Still stuck in bootloop.

Please I need help to fix the problem :(

I’m not an expert developer, but I’m not a complete noob either.

This is the first time I have troubles with a brand new Xiaomi Phone.

It’s the first time I get a very expensive phone, but had no choice (they are getting very expensive), because I always buy a Flagship Xiaomi to get all the community support possible.

And I had to change the ROM to Xiaomi.eu, because the Official Global ROM is full of bloatware :( I had a good experience with Xiaomi.eu ROMs with my old Xiaomi Mi 4 and Mi 5.

At this point I don’t mind going back to stock MIUI Global ROM.

I suppose that with access to boot loader I can flash the Official ROM from PC with MiFlash2020-3-14-0? If it’s the case can somebody show me detailed steps to do that?

For Mi 10 Official Global there is the Stable Full ROM (miui_UMIGlobal_V11.0.2.0.QJBMIXM_4f986c08cb_10.0 ) (2.45 GB) and Stable ROM (umi_global_images_V11.0.2.0.QJBMIXM_20200328.0000.00_10.0_global_09b168ff9e) (3.76 GB). Which One to flash from PC with MiFlash?

I can’t afford to hard brick the device :(

Thank you very much.
