How to enter flash mode
- Boot menu: Hold and until you see a "NOTHING PHONE INFO" boot menu.
- Fastboot mode: Enter the boot menu, select fastboot with and enter with
- Recovery mode: Enter the boot menu, select recovery with and enter with
Installation
1. Select the device in pmbootstrap and run install as normal.
2. To prepare the device for booting mainline, you need to erase some partitions:
$ fastboot erase vendor_boot erase init_boot
3. Then, install a patched bootloader - lplk to allow booting mainline kernel without hacks
$ fastboot flash lk lplk.img reboot bootloader
4. Now you can flash the device with pmbootstrap (BOOT IMAGE CHANGES NOT MERGED TO PMAPORTS YET - CREATE HEADER V2 BOOT IMAGE MANUALLY), as normal :)
Device quirks
- Fastboot appears to not work properly if the device is plugged into the host when entering fastboot mode. In this case, any fastboot command will halt seemingly forever and without action. A command can still be executed by unplugging the device, issuing the command, and then reconnecting the cable; or simply by rebooting to fastboot again without a cable connected. (Has to be verified the bug still exists under lplk)
- UART is not enabled by default. To enable it, you can run:
fastboot oem p2u on
- This device can very likely run U-Boot as its first stage bootloader! After unlocking, bl2_ext does NOT verify lk's signature and that means it can freely be replaced! However...
- This device uses a new flashing protocol, unsupported by mtkclient. It can read partitions, but flashing fails (and yes, I am alive is real and comes from device.):
[SEC_POLICY] lock_state = 0x3
Security deny for [lk_a].
I am alive.
UART
After enabling UART from fastboot, it can be accessed on the motherboard, close to the camera (requires disassembly). The pins operate at 1,7V.
