Hello.

Please install latest Software version, reinstall FTDI drivers and restart PC.

Repeat "Write Cert" operation after PC restart. Try to use different Samsung C3300k/C3303k micro UART cable with 525-530kOm resistor for connection. Try to use another box as UART interface.

bigclive33 · 08-11-2015, 16:20

nope nothing is working. software just straight away gives up without even looking for my phone on uart. ive check the resister that is fine. i wrote a cert file on a note 4 the other night all with the same equipment and everything was fine. its puzzling to say the least

Octopus box · 08-11-2015, 16:41

Please upload *.log and *.logx files of "Write Cert" operation, from "C:\Program Files (x86)\Octoplus\Octoplus_Samsung\LOG" folder and post here download link. We will check where can be the problem.

the phone is going back to a nokia imei as seen on other posts with this issue. i am using the security back up to put this imei back to is original one but still can not write the cert ?

Octopus box · 08-12-2015, 08:50

Please reflash the phone with any Android 4.4.2 firmware from the Support Area and repeat "Write Cert" operation.
Post here results and full Software log of performed operations.

bigclive33 · 08-12-2015, 11:32

some how the imei number has actually changed. all i did was flashed an efs file i found on this forum and the imei number had changed and so far seems to be valid in my country. so for now im not going to play about with the phone anymore lol. should this one get disconnected i shall come back here and try again. (posting what i did here just in case i get another one and will find this thread to remind me what worked for this phone lol)

bigclive33 · 08-12-2015, 19:39

update, i would nly get a very weak bad signal the way it was b4, so i tried to write cert again and still the samething happens. ive reflashed the phone with a rom from support, that hasnt made a bit of diiferance either. i am completely stumped as to why i can not write cert to this phone.

hi, right ive sorted the not attempting to write cert file. octopus does now finally go to write the cert, most of them on the support site fail though, but 2 of them do write successfully but dont work in the uk lol i guess its just a case of trying to locate a good cert file for the uk now
but thanks for your help, i really appreciate it

bigclive33 · 08-13-2015, 18:41

great, i fix 1 problem, now confronted with another.
after trying several cert files i could lay my hands all most will work and i can make and receive calls, but the phone only get a very week 1 bar signal no matter where i take the phone, i have tried different sim cards from different operators but still the same. the phone is mint and never had any damage so i dont see the need to open it up. so i figure it must be a software issue? has anyone got any ideas lol?

Octopus box · 08-14-2015, 09:07

Please make a Factory Reset and reflash the phone, then check, whether phone receives signal normally.

bigclive33 · 08-15-2015, 12:22

flashed with a stock rom from samobile
