I installed the modem and the system set me free but it is still blocked ... there are already 2 cell phones that only charge me but SamTool does not do them ...
I'm not sure I understood you. You installed the modem file that samtool indicated and it worked? Are you saying it deducted your credits but it still won't work with another carriers SIM card and tells you it is an invalid SIM? Did it ask for a code? I see in another thread that the interface provides the following lines during an unlock:
USE [01234567] OR [00000000] TO UNLOCK!
Unlock Successful!
I don't know if you get prompted and have to enter those codes in the phone after inserting the card or if you have to bring up the unlock code via the phone dialer to enter those. I'm guessing since I haven't unlocked a phone with this utility yet.
I also jumped on chat and received a reply that we have to flash A102USQS4ASK4 but that is for T-Mobile I think. They have the expectation that we all do this professionally, and many of us are just looking to do our personal phones (ours, our kids, etc.). They provide minimal support, but I wouldn't expect these issues when they post that AIO is supported without reference to what you need to do to make it supported.
If anyone else can offer directions on how to unlock the SM-A102U that are currently on A102USQS4ASK3 I think a number of us would appreciate it.
