    Hi there, Merry Christmas to y'all everywhere( We don't have Christmas here in my country, anyway.
    Ok. Here we go:
    I wanted to give my Mi A2 to someone else( completely working and smooth like it should be, has AICP Rom for long time), since that person doesn't like totally vanilla ROM, I decided to flash a more feature packed ROM on mi a2(in this case Pixel Experience), I do this, clean flash,following the usual procedure since I'm used to flashing ROM and stuff

    after booting up, everything is sluggish and laggy, even in Phone Setup Wizard, started using phone, setup the apps needed, still laggy and sluggish.. Until that person starts complaining that phone is seriously slow, I say "OK, maybe I did something wrong or maybe this ROM has problems that I'm not aware of" I flash another ROM (Lineage OS), I do the previous stuff, still sluggish, just like previous ROM, exactly same scenario, it doesn't even matter if I have installed apps or just flashed phone, still lags.
    Frustrated, why A2 became like this? Did it hit number of flashing rom attempts?(LOL, such thing exists? Flashing cant slow down the phone unless that ROM has problems) decided to go back to stock ROM, successfully flahed stock, boot up, still sluggish and laggy.. I don't know wth is going on...
    My mind is racing:
    "what is happening?"
    "The phone was just fine when on AICP, after flashing, what happned?"
    "Is it my fault? "
    "Should I have just used factory reset instead of flashing ROM?"
    Guys, there is something wrong
    ,will update the post with logcat and recording if needed and I have the time to do it. Feel free to ask questions.

    The obvious test would be to flash the AICP ROM and see whether it still lags. If it doesn't then there is something about that ROM that's the key.

    And no, there is no limit on the number of flashing attempts ;).

    Was the stock ROM you tried just a ROM or a full firmware suite (baseband, bootloader, etc)? Just wondering whether there is a compatibility problem between some of the ROMs and the lower-level firmware?

    (I assume from your talking about a clean flash that you have been resetting the phone before each flash, but your question about whether you should have just done a reset is a bit ambiguous).

    Hi there. It's a full suite. Has all partition images.
    Device:jasmine(actually jasmine_sprout, not sure why they still use the older codename)
    Build_number: V11.0.28.0.QDIMIXM( Android 10, released in 2021/07/15)
    After that stock ROM, I flashed lineage,since I don't have AICP anymore but will try that too, maybe my poor A2 only likes AICP since they have been together for quite long time LOL
    To clear up what I meant by reset, I meant simply using factory reset option under settings-system-reset option rather than flashing, since I thought flashing was too rash and not needed for simply handing over the phone to someone else.
    Clean flash meaning, wiping system, data(+internal storage for stock ROM) and cache
    Sorry for the late reply, I was a bit preoccupied with other useless stuff :)
    Edit: almost forgot, AICP has mi a2 removed from their download page for some time, not sure when(plus some other devices)

    Ahoy there!
    For custom ROM the usual combo: system, cache, data(not internal)
