This device is based on the MediaTek MT6735.
See the SoC page for common tips, guides and troubleshooting steps

Architecture

Note Note: Even though MT6735 is capable of aarch64, some variants ship with a broken lk bootloader, a broken ARM Trusted Firmware implementation and/or a downstream kernel that compiles only on armv7. Therefore, this device can only boot on armv7 at the moment. Work is being done to replace the stock bootloader with u-boot.

Board

Wiko U Feel has two different board revisions: one using the Tinno p6601 board (like BLU R1 HD, Lanix Ilium L910, QMobile Noir A6, Evertek EverSolo, Smart Art P6601) and the other using the p6609 board. It appears that the current packaged kernel is compatible between these two boards.

UART (p6609)

1.8V UART pins are exposed on the motherboard. Removing the back cover and unscrewing a plastic frame gives you access to them. According to the board, the RX pin is at the top and the TX pin at the bottom. Baud rate is 921500 for preloader/lk, and 112500 for BootROM.

WiFi

As described in the WiFi troubleshooting guide, you need a firmware loader, named 6620_launcher, but it panics the kernel. If you want to debug wifi, then check out the mediatek section on the WiFi page.

Audio

Sound card is detected in alsamixer, but dosen't work


Device Tree

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.
