Greetings, I am here because I used all my ressources to solve this issue.
I have a OnePlus One with XNPH44S (Kitkat 4.4.4).
I installed MultiRom and Flashify
I installed the Patched Kernel ''Furnace'' + Modified Recovery (multirom-20150405-v32f-UNOFFICIAL-bacon-oxygen.zip ) + Flashed MultiRom
I downloaded from Oneplus One official website the OxygenOS 1.0.0 flashable ROM
I extracted ''OxygenOS'' in my ''Download'' folder and used TWRP>Advanced>Multirom<Add ROM to install it
After the installation completed, instead of creating a NEW Rom like it's supposed to do, it replaced my main XNPH44S ROM
I have now a Black Screen and can't navigate the phone anymore.
Of course, the USB Debbuging is disable in the settings so I cannot transfer another ROM to Flash it using TWRP
Even with USB OTG + USB, TWRP does not recognize the USB key
Now my question is...Is it possible to use a fastboot/console to "Transfer" a .zip in my phone storage so I can use TWRP to flash it
My second question is...If it is possible to use any kind of program to "Backup" everything execpt the OxygenOS ( I have 29GB of Data Not backed up )
My third question is... Why did Multirom Replaced my Main ROM instead of Creating another one
I appreciate any kind of answers!
Thank you very much,
Best Regards, BoutchooQc
