Hello,
I recently bought the Volla Phone 22. Following the FAQ, I installed another OS (Ubuntu touch) for a dual boot. I then restarted the phone, but the boot menu is wrong: the option for Volla OS is still there but instead of UT I have a button named "SYNTAX ERROR". Also, the Volla Boot Manager application now crashes every time I click on "ROMs".
Is it a known issue ? How can I fix it ?
Any help will be very welcome !
