[GUIDE][BOOTLOADER][KK 4.4.4] TILAPIA KTU84P- 4.23 Flash Image Instructions - UPDATE

[zhiwlin]

OP update with all files from Android 4.4.4...

I've added to Post 2 with factory image and all binaries files

Can I use the custom TWRP recovery to flash the factory image (since it is zip), or some other way to flash? I want to reset my tablet to factory stock rom.

Also, does this automatically upgrade the bootloader and radio using this factory image?

I failed in bootloader step and got following error from rooted stock ROM 4.4.

C:\platform-tools>fastboot flash bootloader bootloader.img

After searching, now know the root cause. The bootloader image provided in this thread and also on official site: https://developers.google.com/android/nexus/images are both corrupted!

You have to use this image download from grouper's link with MD5: df53028033c9eccf4fe5ba7bc198ce24

Signature Mismatch

I too was receiving the signature mismatch error when attempting to flash the 4.23 bootloader linked on the first post coming from 4.13 bootloader. After some searching I came across this thread that indicated there was an issue with some of the 4.23 bootloader images and tried the one linked in the first post. I had success with your method but the other bootloader image.

Thanks for the write up as I too had no success with the WugFresh toolkit!
