How to flash Adam Image on GCW Zero

You need Linux for that.

1. Download latest PGv1 Release Image
2. Unpack xz: xz -d adam_v2.1_PGv1.img.xz, you'll have adam_v2.1_PGv1.img in the same directory
3. Split image into MBR, bootloader, system partition, data partition:
   • dd if=adam_v2.1_PGv1.img bs=512 count=1 of=mbr.bin
   • dd if=adam_v2.1_PGv1.img bs=512 skip=1 count=30 of=bootloader.bin
   • sudo losetup --show -Pf adam_v2.1_PGv1.img
   • mkdir m && mount /dev/loopXp1 m, where X is the device number from the previous losetup step
   • sudo mv m/gcw0/* m/ - this will copy gcw0 kernel to the root of system partition
   • sudo umount m && sync
   • sudo cat /dev/loopXp1 > system.bin, where X is the device number from the previous losetup step
   • sudo cat /dev/loopXp2 > data.bin, where X is the device number from the losetup step
   • sudo losetup -d /dev/loopX, where X is the device number from the losetup step
4. Git clone Ingenic-boot
5. Apply the following patch or it won't compile:

diff --git a/source/stage2_cmd_tool/stage2.h b/source/stage2_cmd_tool/stage2.h
index 54e6ce6..52b9caa 100644
--- a/source/stage2_cmd_tool/stage2.h

 #endif /*__STAGE2_CMD_TOOL_H__ */

6. make
7. Press SELECT+POWER on the GCW Zero
8. Connect GCW Zero to the PC via USB
9. Run sudo ./ingenic-boot --mbr mbr.bin --boot bootloader.bin --system system.bin --data data.bin

It takes quite some time (around 15 minutes). New firmware would be booted automatically.
