Help: Z3X BOX Samsung Galaxy S6 Edge SM-G925T IMEI Repair w/Marshmallow 6.0.1 - GSM-Forum

GalaxyVibe · 11-19-2016, 04:07

Hello guys. This the first time repair an IMEI on a phone with the Z3X box. The phone is a Galaxy S6 Edge G925T with Marshmallow 6.0.1. This is what I have done so far:

1. I rooted the phone using CF-Auto-Root-zeroltetmo-zeroltetmo-smg925t
2. I dialed *#0808# and activated the RNDIS+ACM+DM+ADB
3. I plugged the phone to the Z3X box and selected my phone model
4. On the "Backup" tab, I selected my phone on the ADB drop down window.
5. I clicked on the "Read EFS" and it went successfully

But when I tried to "Read CERT" to back it up, this is what I get:

So this means that it can not be done for now? Any other way around?

I flashed the original firmware and the IMEI shows again. That is not problem. The thing is that it does not let me downgrade the modem.

Yeap, but at least you can flash it back and the IMEI and baseband would show again

apologized · 11-19-2016, 15:53

to do downgrade you must flash combination first
