[PACK 12]G900f UART factory unlock can't be done

[ceedee]

I have fully functional S5 (g900f). UART cable ok. *#7284# PDA menu done. But phone is not seen by software. If I connect via USB (modem port) it reads IMEI, SW version etc but unlock fails. G901 BSI trick doesn't work also. Any suggestion? For me modem is UART locked or something.

where is software log

I told that phone is not detected via UART connection. Every step is 'error [NO_ANSWER]. You want the log - here it is...

for me it looks like modem have UART comunication blocked (like newer radios in i9505). FYI - phone is "woke up".

Below is the log of USB modem connection

Hi,

Are you sure the uart cable that you are using is working ? tested it before ?

[ceedee]

Yup - selfmade, done many i9300s, s5620, s5610... etc. with it. Cable is not a problem - that's for sure. Or maybe some other resistance should be applied?

if you meant g901 BSI disconnecting trick - I've tried it already
if you meant swaping rx and tx - is not a cable from furious, it's self made cable which succesfully worked with z3x and nspro (yes I know that those boxes have different pinout but making 2-dir conversion plug is super easy)

use uart cable whit 510k resistance and battery trick
works for me
