Hi people.
I have new bricked Huawei Honor 4c with HiSilicon Kirin 620 octacore (Hi6620) Hardly bricked.
I`ve unlocked bootloader and custom recovery used to flash it with my own update.zip from other phone (with LTE support). At the end of flashing - it turned off and bricked.
BUT! After connecting to PC via USB it flashes GREEN and RED leds a few times and after windows determines it as a device with USB\VID_12D1&PID_3609&REV_0000 and named as 䕇䕎䥎 ㌲㔴㜶㤸 .
It is Huawei`s VID. And after a lot of search I found a driver for it - and device became HUAWEI USB-COM 1.0. But nothing else.
No flash utility, nothing. HiSilicon-IDT for K3 processor doesn`t work.
After another searches I found very similar device - it`s named HiKey board. Based on Hisilicon Kirin processor too

This board is base around the HiSilicon Kirin 6220 eight-core ARM Cortex-A53 64-bit SoC running at 1.2GHz and delivering over 10,000 Dhrystone VAX MIPS total performance. The SoC also delivers high performance 3D graphics support with its ARM Mali 450-MP4 GPU.
1GB 800MHz LPDDR3 DRAM, 4GB eMMC Flash Storage and the standard 96Boards microSD v3.0 socket provide high performance. Flexible storage options and connectivity are available through 802.11a/b/g/n WiFi, Bluetooth 4.0 LE, three high speed USB 2.0 ports (1 OTG), an HDMI 1.3 1080p video output with audio, and Maker, DSI display and CSI camera interfaces. The board is the standard 96Boards credit-card form factor powered by an 8-18V DC 2A power supply.

As we can see - it is very close to ours phone.
It is fully documented and has a lot of spec about proc and other.
And in it`s manual written about recovery procedure after damage of ROM - when device is powered on - it is in "download mode" for 90 seconds - abslolutly like mine phone - after 90 second it turns off from windows.
In short - it is ability to write 2 fastboot images (fastboot1.img and fastboot2.img) in RAM, launch them and using fastboot command flash images to eMMC. They use SERIAL COM PORT to manipulate with device.
It uses utility called "hisi-idt.py" - it is a python script for Linux based machines.
I`ve Installed Linux Mint and try it.
And I`ve some result - first image is going fine and I receive "Done"
But second image is always "Failed". And fastboot command "fastboot devices" do not list any devices.
Viewing binaries from my ROM (Fastboot.img and Fastboot1.img) in HEX - I can see load addresses to ROM are the same as in python script. It is 0xf9800800 and 0x0700000 for both images.
But.... have no success. It looks like I`m close to the goal.
Any ideas?
