Did you update emmc firmware?
After update firmware dont write extcd file just update boot config.

If phone cp hardware is ok then its emmc partitions problem.

Its very possible that you overheat baseband IC. Reball it .

listen to me bro have one mother bored with 2 emmc chips one of them working fine with imei and the other one working fine with no imei so baseband ic is ok i tested it it is something wrong with the emmc and my question is how to fix it since it is accepting dump file on jtag direct emmc

yup i think baseband ic is over heat i also face this problem every time i change emmc ic for i9300 sometime i got null imei..

the final solution need too grind the emmc for safety
not over heating the baseband ic..

Hi
This is hw problem of eMMC chip in page size512k and no way for repair
original eMMC B503 is expensive so everyone buy used (second hand) emmc then it's normal sometimes some eMMC have a some problem
