Do you know what's wrong?

After i unlocked with other tool, i get "test results secret" message on the phone. Now I tried with DC-unlocker again, but now i get message: "Demo expired, you must activate dongle". I have vygistoolbox dongle, and according to the pricelist it's free to unlock huawei with that dongle?

Demo expired means you have no more credits. Vygis dongle have demo 15 credits.

Error 31 is boot communicate error . If you use latest version, to check i need error log (only live by msn or other messenger).

test results secret -- is damaged security zone . Other tool damaged it. Dc-unlocker must repair, please give me your Vygis dongle sn, i will upload credits to test.
To repair need select "unlock and repair". Hope you will not have this error 31. ..

Credits added, try now.

[James_S]

Wow it worked!! Thanks!! How much do i owe you?

PS: You added 6 credits, it only needed 3.

[Arunas]

You not owe me, but if later need repair or unlock, you will need activation or dc unlocker dongle, or buy credits.

Ok, thanks a lot!!! Great support

Does it usually need 3 credits? So I only need to buy 3 credits to unlock next time i have one such phone?

[Arunas]

Yes, unlock (or repair) huawei phones 3 credits if have Vygis dongle with out activation. Or unlimited if activation.
