HTC One SV (htc-c520e)
Hacker420 (I have the LTE version of this phone)
To do anything useful on this device, it's bootloader needs to be unlocked. This sadly requires creating an account on HTCDev.
Instructions can be found here. Select "All Other Supported Models" on the right side and press "Begin Unlock Bootloader".
Kernel can be compiled with GCC4, boots, USB networking works. Matchbox and MATE work. Some apps might crash the device. It uses the 16 bit color mode.
- Power + Volume Down buttons (that boots the device into HBOOT, use the volume buttons and power to select Fastboot) or use TWRP reboot bootloader, or
adb reboot bootloader
- Boot to fastboot
- Install rootfs to the SD card or the internal storage with
pmbootstrap flasher flash_rootfs(S-OFF needed for the internal storage)
pmbootstrap flasher flash_kernel
Installing to the userdata partition didn't work, tested flashing Matchbox and MATE, MATE was too big.
