    After dual boot setup, it directly goes to twrp recovery.
    I want to keep the miui as primary and any other rom as secondary(data slot).

    So as per ur suggestion if I make a twrp backup, then formatting everything will solve the dual boot issue.

    So I want to know, should i restore the miui backup 1st, after format, and then try dual boot, OR
    after format, 1st install dual boot, and then restore the miui backup?????
