q: what is "erom upgrade" for db2020 phones (k610/v630/k790/k800/w850) and how to use it?

a:
semc gone crazy with security in db2020 phones, so if anything secure damaged (as they thinks) - EROM not starts phone and phone is completely dead.

in early EROM releases (R3A011 versions) SEMCsec developer done some error,because of that EROM sometimes can't setup GDFS good.

we will see it as RED BLINK during phone power on. and as "gdfs startup error:29" when we trying to flash it.

SEMCsec released then EROM updater, which is upgrade known EROM to new version. that new version solves red blink error (of course, if security units intact). i decided that it is not fair to keep that loader only for emma, so it is embedded in setool2 from now on.

usage is very simple.
select correct db2020 model.
check "use server" in settings (credits will NOT be deducted)
connect phone to COM/UFS cable (USB will NOT work)
press RECOVERY

EROM will be upgraded and your problems CAN be solved.

sadly, SEMCsec not released anything to correct problem, when security units or gdfs totally damaged. they fear of illegal usage
ps.
Если с телефоном такие проблемы как мигания красного светодиода или ошибка "gdfs startup error:29" то надо записать новым EROM
Выбрать модель.
Подключить телефон через COM/UFS кабель.
Поставить галочку на "use server"(лог удерживается не будет).
Нажать кнопочку RECOVERY.
