Hello.

The problem can be with your Samsung Micro UART C3300k/C3303k cable or with Box's COM port. Try to use another Samsung Micro UART C3300k/C3303k cable with 523-525 kOhm resistor inside. Also try to use another Box as UART interface with cables, that You have.

cellularT · 07-09-2014, 13:40

I have the same problem, and the cable uses port resistances are right but nothing firm with four pieces that I have to solve

jusmejose · 07-09-2014, 13:47

Connect a different box and use that as a Modem ....

mr.luckytarun · 07-09-2014, 16:27

1. Disconnect USB cable.
2. Wait for 1-2 minutes.
3. Connect phone via UART cable to the Box.
Serching phone...

lucky4me · 07-10-2014, 04:44

I use an nspro box with a S7070 cable as the UART interface.

Noichuyen · 07-10-2014, 20:59

I have the same issue. When I've tried to unlock the note 3. It kept searching phone and unfortunately I have the Z3X box and I have used it as a modem. Does Anybody know what's wrong with Octoplus Box UART port connection.

I have the same problem as well. Did anyone figure out a solution? Please let me know, thank you.

Octopus box · 07-24-2014, 06:43

Try to use another Samsung Micro UART C3300k/C3303k cables. Also try to use another Box as UART interface, maybe, the problem is with your Box COM port. Post here the result.

ownmart · 07-24-2014, 23:02

same issue here, used z3x box "Write IMEI failed"

Octopus box · 07-25-2014, 06:28

Install the latest Software version (Software), perform the "Repair IMEI" operation again and post here full Software log.

The problem can be with your Samsung Micro UART C3300k/C3303k cable or with Box's COM port. Try to use another Samsung Micro UART C3300k/C3303k cable with 523-525 kOhm resistor inside. Also try to use another Box as UART interface with cables, that You have.
