[SOLVED] Cannot get into flashmode, only fastboot :(

[leeoniya]

Hey peeps, need some help.

I'm currently running LP (E5823_32.0.A.6.200) with an unlocked bootloader, TWRP 3.0.0, Zombie kernel, SuperSU.

I can get the phone into fastboot: Power off, hold vol-up, plug in usb (blue led). In windows I've installed Fastboot and Flashmode drivers after disabling driver signing enforcement. Fastboot from commandline works without issues.

Supposedly, Flashmode should be vol-dn + plug in usb. However, this just boots normally. I DO see a very brief flash of the green led though (which i think should be flashmode), but it continues to boot into system. Since I cannot get into flashmode, i cannot upgrade to MM (E5823_32.1.A.1.163_SG.ftf) using either the Flashtool or Emma (sony's official) since neither can detect the phone. So a couple questions:

Does TWRP or the custom Zombie kernel (also tried AndroPlus) have any effect on being able to enter flashmode? If so, where can i get a stock recovery.img and boot.img (for LP)? I have tried extracting the kernel.sin from the LP ftf and unpacking it to flash with fastboot, but it keeps telling me "image is not a boot image". So I'm kinda stuck

Any advice?

thanks!

solved it by switching USB ports, maybe Win was caching the Fastboot device on that port.

Same thing was happening to me, I was using a work laptop and it has a charging USB port on the side. All other USB ports were data.
