hi, I bought a galaxy s5 from France, and has the block operator, which process should I do with the octopus box to unlock it?

Hello.

You have two ways, how to Unlock the device.

I. Free way, no need credits, but after unlocking, phone's IMEI will be changed:

1. Root the phone.
2. Perform Wipe Security procedure ("Repair Security/Wipe Security"button in the Software).
3. Write Certificate ("Write cert" button). Please check your PM, we have sent You several Cert files.

Look here video manual: http://forum.gsmhosting.com/vbb/10634587-post74.html.

Note: After performing steps 1-3, your device would be unlocked and IMEI changed to the one from Certificate file!

II. Factory Unlock, need credits, but after unlocking, phone's IMEI will remain the same:

1. Buy Credits (Please, contact to our managers in on-line Sales Chat at GsmServer, they will help You with credits.).
2. Go to "Support & Options" tab in the Software.
3. Enter Username and Password, which have received, when You bought credits.
4. Connect the phone to Box via Samsung Micro UART C3300k/C3303k cable.
5. Press "Factory Unlock" button in the Software.

how many credits does it take to unlock a smartphone?

Octopus box · 11-11-2014, 12:12

You need 9 credits to perform Factory Unlock operation once.

I have all the cables but no Micro UART C3300k/C3303k cable??, okay UART 530K?

Octopus box · 11-11-2014, 12:52

You can try to use 530k cable, but this may cause issues with connection.

MoRpHeUsHaCk · 11-11-2014, 13:01

I bought everything for samsung and lg, but this cable can not find it ;/

d_bug · 11-11-2014, 15:14

same here. not connecting via rextor uart cable, replaced resistor with 560K, same. what should be the right resistor value for this?

usb reading is ok tho, very tempted to do unlock via cert write but will wait for workaround, i want to use my credit. :P and retain my imei. hehehe.

Octopus box · 11-11-2014, 15:39

You should use Samsung Micro UART C3300k/C3303k cable with 525kOm resistor.

d_bug · 11-11-2014, 15:42

I purchased the cable, however, strange that no that is not included with the octopus box samsung and lg

d_bug · 11-12-2014, 07:36

did you managed to connect yours? replaced mine with 525K resistor and still not connecting, used a 3rd party cable used to unlock other units with the right resistor value and still cant get it to connect. i should look for logs from others who successfully unlocked this particular model via factory unlock.

d_bug · 11-12-2014, 09:22

connection is ok with 510K resistor, also check for reverse rx tx pins.

success!!!

MoRpHeUsHaCk · 11-12-2014, 12:10

ok, but i'm buy yesterday the cable from internet...for security
