Send 15-dig NCK to Nokia 100 via F-Bus
 

I've got a 15-digit unlock (NCK) code from the operator to unlock my Nokia 100 (RH-130). When I enter the unlock code like this #pw+XXXXXXXXXXXXXXX+7# (where XXXXXXXXXXXXXXX is replaced with my actual unlock code) the phone throws the message "Not allowed". This should mean that amount of allowed attempts (3?) to unlock the phone have been exceeded and further attempts will not unlock the phone.

Now, I think, I have two ways to unlock the phone:
1. to reset the counter of failed unlock attempts ("Key Code count") from 3? to 0 and then try to enter the unlock code again.
2. to send the unlock (NCK) code directly to the phone through the F-Bus.

I guess in both cases I would need some kind of flashing box.

My questions:
1. Am I thinking right, or are the an other ways to unlock the phone?
2. If I need a flashing box, which one will you recommend? I'm interested to spend as less as possible. Will for example a JAF box together with a Nokia 101 service cable do the job? Both can be found on aliexpress, box for ~20$ and cable for ~5$.

dont know about jaf.. but purchase ufs(without hwk) + infinty best can do your job..

Or just contact with any technician shop .. it will be cheaper than purchasing boxes..
