Varvaris, so you're saying you can install a Xiaomi.eu developer ROM via updater app, directly from that unoficial china stable ROM? It shouldn't be needed TWRP? Cause of signature fail error.
I'm more or less in same situation, and looking for a way to go to a xiaomi.eu developer from that ROM (7.00.66.00 stable china) as simple as possible, and preferably doing all steps through phone.
So far, from what I gathered it seems I won't be able to put TWRP through mirecovery (well, it does, but after restats it goes back to mirecovery instead of TWRP) and then directilly install a xiaomi.eu dev ROM.
Thing is, info is still a bit disperse and multiplied, that is hard to understand what would be the ideal method to change ROM.
I know as well that beta xiaomi.eu 6.2.25 ROM has TWRP included. Would it be possible to just install this ROM directly from mirecovery from that room mentioned above? Or you can't go from a stable unrooted ROM to a Xiaomi.eu beta without TRWP by any means?
Also, that link it's not working, but it's not hard to find a link to those xiaomi.eu developer ROMs download.
Any help would be greatly appreciated. Thanks
