Did you update it by formatting? If so, the data in your phone will be damaged.

Yes I flashed the ROM and I know the risk of losing the IMEI during this process. Nevertheless I've got an IMEI after the flash. But it says invalid. Even if I change the IMEI - always invalid. Any suggestions?

Yes, version 20170307 how do I solve the problem?

Right, if you use SP-Flash and choose Format, then your NVRAM will get deleted. You should only use update or download, all other can kill your phone.

If you do not have a copy of your NVRAM folder, you can only try to install your original firmware or try the MTK engineering tools to set the imeis again or search for mauimeta or chamelephone, those two apps may help, but it not always works.

Please give an instruction on how i can update my phone... will it work if i extract the rar files & convert it to zip file & run the wireless update & choose local files ? thank you

Ah sorry, I've misunderstood the admin, I didn't choose download + format in the sp flash tool. I used only download to flash the new rom.

That is strange then, because SPF should not overwrite your NVRAM. But you can still try my suggestions or even try a re-flash again.
