thanks,but i am not stuck in a bootloader loop,i install again /e/os and its works,but i want to install Ubuntu toucth and for that i need to install first the rom stock on my F4
thanks for the advice,yes and same issue,apparently the partition frp are missing,is it due to /e/ os? and how to repare it?i look evevrywhere and found nothing
That means you didn’t unlock critical partitions, you’ll have to run fastboot flashing unlock_critical, beware that this will wipe your data (which you probably don’t care about anyway )
I don’t really understand why you suddenly can’t flash critical partitons anymore, when, according to your previous screenshot, you just did.
Did you use any commands in between?
My advice would be, move this over to your Ubuntu laptop, so we can rule out Windows doing something weird.
