Hi, I have the opportunity to buy a second hand Mi A1 with Pie or a refurbished Mi A1 (I guess it comes with Nougat?). What do you think would be the best thing to do, buy the one with Pie and wait for the Pie /e/ version to be released in order to avoid problems, or buy the one with Nougat, update it to Oreo and the install /e/? Is it even possible to update it from Nougat to justo to Oreo, without having to jump automatically to Pie?
The pi/e/ build for tissot or MiA1 may take a couple of months I guess. We just started the code base upgrade for Pie. The MiA1 stock ROM is nougat.The way I went was my stock nougat build I upgraded to stock Oreo version 9.6.4 and then came to /e/. The reason why the stock oreo version was old is because there were certain firmware upgrades made to the later versions of Oreo which made the switch to /e/ difficult for some users.

Thanks @Manoj So if I understand correctly, the safest thing would be to update from Nougat to max. Oreo . 9.6.4 and from there install /e/. I guess I’ll have to flash this 9.6.4 version, as I supposed that the phone (in the settings menu) won’t let me choose which Oreo version I want to update, right? By the way, anyone was succesfull in downgradin from Pie to Oreo? (because of the supposedly anti-rollback system…)
You are right . The system will directly pick up the latest updates and you will eventually end up with Pie. Which will be a problem to roll back. Not sure if LOS 16.0 also works is you come from Stock Pie on MiA1.
Ok, thanks. Do you know where I can find the 9.6.4 oreo version to flash it? And if I get a phone with Oreo, (for example Oreo 8.1) there’s no problem to flash an older Oreo version (ex. 8.0) right?
Thanks @Manoj. Unfortunately, the refurbished one as well as all second hand mi a1 have already updated to Pie, so I 'll have to leave the flashing for later, when /e/ develops Pie, so I can flash it from a Mi A1 with pie without major issues.
Guess you are right to wait @graz. The chances of messing up the revert to previous versions are too great. Hold on for a couple of months the Pi/e/ ROM for tissot should be out.
