[YotaPhone] veeblefetzer:
Thanks guys!

Same here. All of fastboot commands end with status OKAY (including erase cache), but the phone still stuck at boot.

I tried with the Chinese firmware, version: 4.4.3-S01-003-CN1.0.3.32a, which I downloaded from ftp://fw.ydevices.com/ while the site was still alive.

The content of the firmware:

C:\Program Files (x86)\yotaphone_flasher\firmware>tree /F
Folder PATH listing
Volume serial number is 0000008B 09A6:99FE
C:.
¶ boot.img
¶ cache.img
¶ dt.img
¶ emmc_appsboot.mbn
¶ emmc_appsboot.raw

+---radio
NON-HLOS.bin
rpm.mbn
sbl1.mbn
tz.mbn

And I had to change this:

fastboot.exe flash fsg firmware\radio\fsg.mbn

To:

fastboot.exe flash rpm firmware\radio\rpm.mbn

since firmware\radio\fsg.mbn does not exist in 4.4.3-S01-003-CN1.0.3.32a.
