[Bite_my_shiny_metal_ass!]

I bought second hand z4 from some guy who work for Sony. How to flash normal (not prototype) rom in this device? Everything works fine, Camera., Apps, Android os is 5.0.2 kernel 3.10.49, everything is smooth, but there is anoying message "You have crash artifacts to upload" all the time!? If I cant flash normal rom, is there any method to kill that message? Thanks..

I believe that sticker talks for itself and my advice would be not to be so open about this transaction.

In any case unless you have an EMMA account with relevant privileges you can't do much.

If you are lucky enough and Sony enables OTA updates for customer acceptance firmware applicable to the variant you have then at least you might get a firmware update in the future. But if you have as you say the crash handling app installed then probably you have an quite old FW which might not get any OTA.

Is there any way to instal new firmware without OTA? I think for z4 actual android official version is 5.11? If i kill process com.sonymobile.crashmonitor.system and com.sonymobile.crashmonitor.ui anoying message "You have crash artifacts to upload" is gone. Z4 is alredy long time on the market, so stickers now dont have much point anymore?

The last part is something you need to discuss with Sony but I don't believe a prototype unit on the loose is something they don't take seriously.

If I were you I'd ask the seller to take it back and refund you because as I wrote the only option for updates you have is either EMMA access with the proper permissions to download customer acceptance firmwares, someone with such access to give you the firmware or sony to enable OTA for customer acceptance firmware. The latter happens some times.

With the current firmware you have you can of course kill as you said some processes to get rid of the crash monitor app and notifications but there are still other debug bits enabled. If the firmware has root access enabled - there are such debug firmwares and you can check that from adb shell with su - you can clean it up a bit more.

That is all I can provide as info.

Solution is very simple. I download latest firmware 28.0.A.8.260 with XperiFirm and flash with flashtool and everything works perfect! No anoying messages anymore, nothing..

Prototypes have a different bootloader so you can't flash retail firmware on it and vice versa.

Up to Z3 tablet this was valid also for tablets, if they changed that in Z4 then you are lucky.
