Acabo de leer en xda ( o eso me ha parecido entender, que mi ingles es pésimo) que han conseguido desbloquear el bootloader mediante el flastool 707
Copio y pego

maybe...
but maybe not need? Disassembly strings from fastboot_707:

ROM:0000A9D5                 DCB 0, 0, 0
ROM:0000A9D8 aImageIsSignedO DCB "image is signed, old state is unlock, relock it\n",0
ROM:0000AA09                 DCB 0, 0, 0
ROM:0000AA0C aImageIsNotSign DCB "image is not signed, old state is not unlock, unlock it\n",0
ROM:0000AA45                 DCB 0, 0, 0
ROM:0000AA48 aGetLockState_0 DCB "get lock state: UNLOCKED\n",0

Anybody have another boot for check?

bootloader 707 will unlock phone automatically if start booting with ANY unsigned boot.img

I did so:

1. flash new 707 EMUI recovery from this archive (unpack & start .bat)
2. repack boot.img from 707 without signature (may take here)
3. flash fastboot_707 (here)

fastboot flash boot <you path>\fastboot.img

answer must be:
sending 'boot' (4730 KB)... OKAY
writing 'boot'... OKAY

4. reboot

fastboot reboot-bootloader
rebooting into bootloader... OKAY

5, flash boot

fastboot flash boot  <you path>\boot-707-unsign.img
sending 'boot' (4730 KB)... OKAY
writing 'boot'... OKAY

6. reboot phone

fastboot reboot
rebooting.

..
in this moment (boot unsigned kernel) takes place Unlock
phone is started with new kernel (3.0.8-50)

7. back to fastboot

adb reboot-bootloader

8. check the unlock

fastboot oem get-lockstate
... INFOunlocked
OKAY

9. back to android and enjoy!

fastboot reboot
rebooting...

Many thanks VKuk!!!
Where did you get the fastboot_707? (Flashing the b707 update.zip will do the job right?)
It works only by flashing a boot.img via fastboot, or it will work also by flashing it via recovery?

Need fastboot with signature, I extract from update.zip/update.app
Also, you can flash update.zip via recovery, but maybe you will need another unsigned boot for unlock
You may just remove first 0x7ff byte from any boot.img from stock rom or use DD copy from device.

I've noticed that after unlock, if you flash back a signed boot.img, the status is changed to "relocked" instead of just "locked", maybe it'll void the warranty!
PS: a little typo in vkuk instructions (thank you man!) -> fastboot flash fastboot fastboot.img
