LED:0x000000BD FAddr:0x00005E43
kindly tell me how to solve this case

Hello.

Baseically LED:BD means damaged SMART system file(s).
Bad based on your provided story - could be damaged one or few (any) system files, necessary to check thaem by Ctrl-x report.
Also could be haeds issue (they can't write), you didn't check them and after modified 93 writing attempt it became damaged.

how did u edit 93 sys file this model. is it M11 or M15 family

In that case be necessary to use an external programmer with 1.8 Volts.
Read ROM by that programmer, patch ROM in utiltiy then write patched ROM dump file back on the PCB using the same programmer with 1.8 volts.
Then SED be bypassed and firmware be accessible for further diagnostics.
