For a new version of this project (P10 Lite Toolkit) have a look at this thread.
The latest build of this project is still available.
But anyways, i'm not responsible for any damage done to your device!
Pls, before u upgrade ur single-sim to dual-sim, READ THE INSTRUCTIONS!
According to this post i strongly recommend that u check if your device is SIM-unlocked, before u flash any SIM upgrade! It's not guaranteed that u encounter the same issue see this post there were no problems after the unlock on an already flashed device.
According to this post and an personal encounter of that behavior, there are a few devices which ends in an "black screen" after an "dload" based firmware update. - The only solutions to fix this "black screen" problem are currently the "Service-Center" or DC-Phoenix.
(For the DC-Phoenix solution see this post, there's everything explained and linked.)
Since i was informed about this problem i searched the web for 2 things...
1) Why this happens?
I found no answer so far... (i think, the update script went wrong or something couldn't be written during the update...)
2) Which devices/builds can encounter this problem?
So far i saw, its "LxxC02Bxxx", "LxxC440Bxxx" and some other maybe.
