Would like to restore my old flash backup

[vikasnarula]

i would like to restore my old backup files (below files), which i created while converting CEX to DEX.

1. flash_eEID_35500.bin
2. flash_stor_35500.bin
3. lv1_dump_35500.bin
4. lv2_dump_35500.bin

i converted back to DEX to CEX but getting invalid PS3ID error while connecting to PSN. i am suspecting the restore might not done properly during flashing (my-original-cex.EID0.NORBIN)

i basically want to restore my ole lv2 backup, suspecting this issue might resolve after restoring.

please guide me the way to restore my old backup without using any hard mod.

Have you changed Target ID? Have you before changing IDPS? Even if you restore lv1 and lv2 dumps this give you nothing because they are memory dumps not dumps from physical not volatile devices or some area of this device. They are dumps from RAM. ;]
