SGP771 brick after unlocked and flashed 'boot.img' extracted from AndroPlusKernel v4

[Wei Xu]

HELP: i had been going to flash MR by myself, but when i tried to unlock it and flashed the rooted 'boot.img' extracted from 'Z4T_SGP771_AndroPlusKernel_v4.zip', i don't get the 'supersu' on the desktop properly, after tried a few times, i did a factory reset, it now hangs on boot logo, there is no response to 'power' button long pressed down, looks it will power down until battery goes up, does anyone also experience this? how can i restore this?

The link i'm following:
cwm-twrp-android.net/download/sony-xperia-z4-tablet-lte/
it prevents me paste the outside link since this my first post, so i removed http prefix.

I solved it by myself, after pressing 'Volume Down' + 'Power', it reboots, and looks the factory reset did nothing, it's weird.

On the .260 firmware AndroPlusKernel v4 won't work. I had the same thing when I accidentally flashed v5. You'll need v10. Also, download this stuff from official sources, look in the AndroPlusKernel thread here on XDA.

So, get into fastboot in some way (I don't know how I got back into it, just hammered the volume rocker) and flash the correct v10 boot.img.

Hi,
to go in fastboot mode press and hold down volume up and connect to your Pc, the led become blue
To go in flash mode press and hold down volume down and connect to your pc, the led become yellow for a few seconds so you must be fast to enter the command in ADB

Thanks a lot for your comments, i have root it successfully, is there anyone made it to flash MarshMallow? i tried to update it with TWRY with officially binary SW_binaries_for_Xperia_AOSP_M_v01_2.zip, but it tells 'Could not find 'META-INF/com/google/android/update-binary' in the zip file', does anyone know how to survive this?

I also find a AOSP version 'AOSP_L_MR1_160113_karin.zip' from www.androidfilehost.com, but it only contains image file, i tried to flash them all, others(boot, userdata, recovery) are all ok, but it hangs at flashing 'system.img', i terminate it forcely after waiting for 20+ mins, the system boot up back to 5.0.2 after that.

If i use TWRP to install this zip, it tells the same error with the official binary, anyone know if this will work?
