Kali ini saya akan membahas cara mengganti emmc tab evercoss AT7J. tablet ini menggunakan chipset spreadrum SC7730
Langkah-langkah pengerjaannya:
- Siapkan emmc type BGA 153, kali ini saya mengambil contoh copotan dari asus, jadi partisi GP1nya masih ada, tapi abaikan saja. karena tidak berpengaruh.
- Seperti biasa, factory reset, setelah itu boot partition pilih Boot partition 1 is enabled for boot lalu klik write
- Pasang emmc, flash menggunakan SPD_Factory_Tool_R2.9.9015, jika belum punya download DISINI untuk firmwarenya pakai versi ini DOWNLOAD.
- Setelah selesai coba nyalakan dan imei langsung muncul.
