    Hello.
    As in the subject, I have a problem with the m4 aqua phone, it just can't be started.
    The sony logo just pops up and it keeps restarting.
    Does any of your colleagues have any ideas what could be the reason?
    best regards

    Bootloader, motherboard to be replaced so that possible.

    You can try to re-load the ROM. In addition, I do not know about the M4, but in my M2 there is a reset under the card cover. Good luck.

    Hello and thanks in advance for the suggestions, but unfortunately none helps.
    Attempting to reset or using the off key does nothing, the phone only turns on for 2-3 seconds to the sony logo and the reset is similar when connected to a computer
    it is impossible to upload the rom because the phone is only detectable in the flashtool for a few seconds.

    I do not think the phone is in perfect condition, I have read a lot on various forums that this is a software defect but a problem with uploading.

    A very common glitch with the M4 Aqua -> CPU reball

    A typical malfunction of this model - it is enough that one signal does not appear and the phone restarts.

    Processor. It's best to do a reball. If you can't (no sieve) then the CPU reflow.
