After ATF Software successfully Lists the Partitions Found on the Phone, click “Backup Phone Data” so you will save your IMEI, Simlocks and other important data safely.
Now Let us write Boot Files which you downloaded from Step 3.
Extract the RAR file and then write the 3 RAW Boot Files 1 by 1:
5a. dbl_RM-XXX.bin <— Write this to 0x4D – DBL Partition
5b. osbl_nokia_RM-XXX.bin <— Write this to 0x46 – OSBL Partition
5c. amss_adsp_RM-XXX.bin <— Write this to 0x0C – AMSS_ADSP Partition
Click “SP UNLOCK” if you want to unlock your phone after fixing the BOOTS.
Flash the WP_OS partition using your regular ESCO Flash Files. This will have the same effect as you will flash the phone via USB… but via eMMC Direct, it is faster and does not care if your KEYSTORE is damaged or erased.
Write Flash file to 0x48 WP_OS Partition.
Flash File should be the BOOT file and should be more than 300 MB in size.
It looks like this:
RMxxx_11111_prod_111_11_boot.esco <— 300+ MB
*** WARNING: Everytime you flash your phone with another firmware, you will always RESET the SP Lock status and RESET the SP Lock Counters. To avoid your phone from getting RE-LOCKED, always make sure to UN-CHECK the “XXXXXXX_prod_generic_amss.esco” flash file before you click the FLASH Button. By Skipping this file, you can always re-enter “00000000” to unlock your phone again after flashing.
