I lost the IMEI numbers on both sim slots after maybe a bad flash. I have read days worth of topics for other MTK devices.
I did a format with the SP tools for MTK devices, reflashed ("downloaded") a backup from needrom.com and still no IMEI. I can use the MTK uncle program after rooting the phone, write the IMEI numbers but after a factory reset the IMEI numbers are gone again. When I start WIFI, I get the NVROM error as well making me think that my NVRAM is corrupt.
Any idea how to fix the NVRAM once and for all?
