Repair IMEI with SN Writer (for almost all UMI(DIGI) phones)

Lannig

Hello, I've just registered to say thank you. Not an UMI user, but this tutorial found through a Google search and applied successfully to another Mediatek phone is the best I've found by far.
Again, thank you.

Check in Windows device manager whether a Preloader COM port appears for a few seconds after connecting your powered off phone to USB. You might need to reinstall the drivers.

Hi! I have an umi Rome and in the site http://www.imei.info/ says that my umi rome is an UmiEmaxmini. This is normal?

Algo más fácil es entrar en el teclado
*#*#08#*#* y poner el IMEI guardar.

Something easier is to enter the keyboard * # * # 08 # * # * and put the IME, and save

Hi,
Thanks for that tutorial that helped me recovering my IMEI numbers lost on an UMI Z after upgrading to N.
By the way, I've apparently lost my serial number as what the phone shows now looks auto-generated : 0123456789ABCDEF

Does this tool work on recovering that SN number (there's a pic showing some ESN write option in the tuto) ? What should it look like on the box sticker ? I can see a lot of numbers but don't know which one could be the serial number of the phone.

Hi,
The SN Write Tool is able to permanently change/recover the IMEI numbers by writing the nvram partition. Android apps can't do that since the nvram partition cannot be accessed from Android - it contains raw data, not files in a filesystem. Your solution is just a temporary one that saves the changes on the userdata partition, so after a factory data reset you'll lose your IMEI numbers again.

Hi. My serial number is gone. It apears 123456789abcdef. How to recover.

Hi,

Same thing happened to me, got this S/N 1234567890ABCDEF. Anyone facing this or knows how to fix it ? Warranty will surely be void if I can't recover a proper S/N
