[Solved] NVRAM corrupted - Redmi Note 2 Q&A, Help & Troubleshooting

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

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.

good luck

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)

How to fix? I get invalid imei too

[q] efs backup

Hello,
I've backed up my EFS with TWRP 2.8.6.0 but when i rebooted my phone it said that i had no service.
What to do? Want to install Liquidsmooth rom but i'd like to still have my EFS so i don't lose my IMEI
PS: I've flashed my rom to stock again, i can make calls again. But i still want to backup it and install the rom.
Thanks in advance!
Makes no sense, to backup efs just copy the whole directory to your pc -only requires root.
@ha966: you lost your IMEI probably because TWRP 2.8.6.0 was to big, it overwrote some neigbbour-things and flashing your modem again had repaired it. The corrected version 2.8.6.1 is online now.

Yes this is correct, found out the hard way. Happened to me aswell
Flashing stock rom with odin fixed mine, but i did have efs backups anyway
Try flashing stock first before trying any efs restoring

Can I restore a nandroid backup using SP flashtools as I have no custom recovery?

I have an MTK6580 phone and MTKdroid tools does not work on this chipset so cannot install any custom recovery, have made a CWM nand backup with onandroid online backup, all seems good and have it saved to SD and PC. I want to try and port a recovery to my phone but want to know if I can somehow 'convert' my nandroid backup to one that SP flashtools will recognise and flash?
I have a full stock SP rom to flash if it all goes wrong, so I wont brick it, just would rather be able to flash my current rom thats all sorted out by me already. I 'assume' I can just replace certain files/images from backup to stock? Would that work???
Alternatively, if anyone knows a better way to backup and restore the full phone, not just apps which Ive also backed up in TiBa that would be great, or if anyone knows how to get a recovery onto this phone... uhappy u580
Thanks.
