Taigi, aparatas jau root'intas, bet noras pasidaryti FF (full flash) backup'ą niekaip nepraeina. Beieškodamas Stock ROM'o (sėkmingai radau rusų forume) kartu su juo parsisiunčiau ir serviso programėlę "SP Flash Tool v5.1352.01", kuri turi funkciją READ BACK, t.y. nuskaito telefono atmintį ir išsaugo faile. Tačiau viskas nėra taip paprasta, iškart kyla klausimai:
1. Kokį telefono Prestigio Multiphone 3400 DUO FF ilgį (dydį) nurodyti programoje formatu "0x00000000"? Gamintojas nurodo:
Internal Memory Size 4 GB
Čia FW aprašas (Android scatter):

Programoje "SP Flash Tool" yra MEMORY TEST, kuris pateikia tokius duomenis:
EMMC :
EMMC_PART_BOOT1 Size = 0x0000000000200000(2MB)
EMMC_PART_BOOT2 Size = 0x0000000000200000(2MB)
EMMC_PART_RPMB Size = 0x0000000000200000(2MB)
EMMC_PART_GP1 Size = 0x0000000000000000(0MB)
EMMC_PART_GP2 Size = 0x0000000000000000(0MB)
EMMC_PART_GP3 Size = 0x0000000000000000(0MB)
EMMC_PART_GP4 Size = 0x0000000000000000(0MB)
EMMC_PART_USER Size = 0x00000000E7000000(3696MB)
Tai pagal mano logiką READ BACK reikia nurodyti:
Start Address: 0x0000000000000000
Length: 0x00000000E7000000
Ar aš teisingai suprantu, ar kažką svaigstu?
2. Kaip esant reikalui paskui tą FF sukišti atgal į telefoną?Juk FW reikalavimų jis neatitinka ir pjaunasi su "Android scatter" aprašu...
