Hi,
I messed up my NVRAM, no IMEIs nor MACs...
Can Someone provide me a full NVRAM backup or a working solution for restoring IMEIs?
(no luck with IMEI&SN Writer so far)
Thanks
Manuel
If you flash a stock ROM that is flashable with SP Flash Tool, this will probably restore a working NVRAM. But this is not for the faint-hearted. If you can't find such a stock ROM, then you can try this custom ROM: http://www.needrom.com/download/xiaomi-redmi-note-2-hermes-cinafoniaci-rom/
As I said, this is not for the faint-hearted. If you are scared of trashing the phone, don't try it.
PS: next time, backup your NVRAM with TWRP recovery.
Try this:

Thanks for your help,
flashing stock rom with SP-Flash tool doesnt worked for me.
Restoring the files is only a temporary solution till next phone wipe.
I managed to wirte back my IMEI to nvram with "MAUI Meta", restoring Wifi and BT MAC with "SP Meta".
You find both tools on "needrom".
Does anybody know if there are other valueable things i have to restore after a nvram wipe?
(still searching for an backup, just toi be sure)
