Hi,
I have got an UMI eMax.
I formated the whole flash except bootloader to earase the nvram partiti ...

Hi,
Under point 10 in the tutorial:
''NOTE: If the process gets stuck at this point what the screenshot shows above (switched to META mode), disconnect the USB cable for a few seconds, then reconnect it and the process will continue.''

Worked fine for me. Have UMI Z and erased my IMEI when trying to flash latest NOUGAT update, which doesn't work for me (puts phone in bootloop). Downgraded back to V7.01_20170601 ROM and used tool to restore my IMEI numbers. Only thing is that I didn't select the Wifi address on page 3 because it wouldn't autogenerate a number. As my wifi was working perfectly I decided not to change what was in the phone, and everything worked out.

\n\nHi,

I try to repair my Umidigi 4/64 with SN Writer without succes.


The process stay on "Start searching Kernel..." and after i return to previous menu (where you enter your IMEI) without error message...
Like you can see on the screenshot i have the vcom driver installed and i previously flash my phone with SP Flash Tool (of course that's why i have an IMEI Probleme) so the driver should work.

Any idea ?

Edit: I'm on Win10

I also try with an older version of SN Writer and i get this message

Hi,
Did you try to disconnect and reconnect your phone at that point? Also, there's a newer version (v1.1744) of the SN Writer Tool provided here. Please try to use that. Moreover, don't forget to use the database files of the same ROM version, that you have currently installed on your phone. The database files are not multiversion compatible.

Yes i have try io disconnect/reconnect the phone but nothing happen and i use the same database as my phone.
I will try yhe last SN Writer,  i cross fingers ^^

Thanks

It seems the latest version has some bugs. I linked the earlier, v1.1728 version. Please download that and try again.

I have try a lot of earlier version with two different PC (win 8 and 10) with the same result, the phone is lock on the umidigi boot logo, i need to do a long press on power buton to shutdown the unit.
I'm on the last rom of the Crystal 4/64 V1.1_20171023 maybe the next update can resolve my problem ?

\n\nO imeis da minha umi plus e MTK 6757 desapareceu, está apresentando como desconhecido, tentei tudo, usando a sala original, as ferramentas para escrever imeis estão falhando, eu não tenho backup nvram, já recebi o celular de outra pessoa, então Para tentar resolvê-lo, alguém teria que fazer backup do chip flash ou nvram para tentar recuperar o imeis.
