Mediatek GSM/HSPA/LTE capable CPU.
Cheapest phone I have found so far is [[ZTEObsidian]]. There is another developer working on the postmarketos with another MT6735 based device.
h2. ROM Bootloader
Uses same standard USB profile as [[Fernvale]]/[[MT6260]] and [[MT6261]] based devices. Same baud rate of 115200.
- Plug in Micro USB cable
- remove battery
- start a bootloader tool like "simple-serial.py":https://github.com/craigcomstock/mtk-open-tools/blob/multi-device-support/simple-serial.py (very much work in progress tool to report chip-id on various mediatek devices)
- press up volume button until beacon response is given and chip id should then be reported
h2. Memory Map
config block seems to be at 0x20000000
chip id at 0x20000008 reports properly as 6735
