Users owning this device
Wiko U Feel is based on Tinno p6601 board (like BLU R1 HD, Lanix Ilium L910, QMobile Noir A6, Evertek EverSolo, Smart Art P6601).
Sound card is detected in alsamixer, but dosen't work
I couldn't find the official dtsi source code, so i decompiled the dtb blob from the stock rom with dtc command line tool. Unfortunately with this method we don't have the comments.
How to enter flash mode
Fastboot is broken. It gives Unknown Chunk type, but it is possible to install pmOS with TWRP. Refer to Android_Recovery_Zip_Installation for installing.
Flashing with proprietary program SP Flash Tool also work fine. Tested with flashed emmc boot partition and system partition stored on external sdcard.
