greatelias Hello,

greatelias error failed to initialize EMI from preloader,

Seems like external RAM is not properly working,
since this is eMCP chip with integrated RAM inside the eMMC, so try to resolder your chip precisely.

greatelias 2 reson can make this problem
1- if the emcp have bad ram
2- the lines of the ram under cpu have problem short or cut

pull out the emmc and format it and mount it then flash it by spflash tool

AbdallahHassan thanks

managed to resolder emmc , flashed successfully but only turns on and works for some seconds and reboots itself,could this be a sign of bad ram since have checked for shot but none,no current draw when connected to power supply

greatelias Is the replacement ic you are using new or used one?
If your IC is not new, you may try to replace another IC once again to make sure the RAM is indeed problematic.
If you are using a new one, then you can try to rehot or reball your cpu.
