yes sir, my phone's rooted right now and I have to flash another stock rom with different firmware so that I can update but my problem with imei and nvram warning is still there. my question sir is, aren't there any other way to make the fix permanent? my friend can flash and restore factory settings without losing his imei. I accidentally format flash with spflash tool when I'm following a guide that says I have to do format+download to revive my phone from deadboot.
