Hello.

All Certificates files, which we have, are present in the Support Area (press "Go to Support" button at "Support & Options" tab in the Software) in the folder "Samsung/FOR UNLOCK ANDREPAIR/Certificates/".

Also, look here: http://forum.gsmhosting.com/vbb/f684...-list-1320364/.

I tryed to install al certificates files but I've ever the same situation...
The new manual says to wipe security but in the programm there isn't the function

SM-G800F is Exynos CPU-based device, not Qualcomm CPU-based, there is no Wipe Security/EFS operation. Just write IMEI Certificate. And post here full Software log.

Also, if You want only to unlock the phone, make Unlock operation, no need to write IMEI Certificate.

Select correct Network Mode, then try to select Network manually.

mirko112 · 04-16-2015, 14:21

If I select network mode: only gsm, it works
If I select network mode: only WCDMA, it doesn't works

Try to make Factory data reset and wipe cache partition and re-flash the phone with other firmwares, no other solution.

Never. SM-G800F is Exynos CPU-based device, not Qualcomm CPU-based, it doesn't have QCN.
