N920A write cert problems & solution here with GCPro

[toutanje]

Just wanted to share in case someone else run into same problem... phone was on PB2 firmware to start out with.

I unlocked using z3x, then came back to gcpro and try to write imei using usb. It gave me an error saying I need to reset msl or reset efs.

I ran exynos unlock on gcpro the 2nd time, and even though it detected it was unlocked already, it still performed the operation. I went back and did imei write with usb again and this time worked perfect!

This has been mentioned countless times already. First use Exynos unlock to reset the MSL to a generic one. Then write cert through USB, no root.

Yes... that is what I said the first time.

All I was saying was I did exynos unlock first but with z3x and when I tried writing cert with gcpro it didnt work. The 2nd time, I did exynos unlock with gcpro instead then cert write worked.

I have one that won't work.

Freshly flashed PB2, and still says to Reset MSL after doing Exynos Unlock. Knox is still intact

Keep trying Exynos unlock until it finally works when you write cert usb. I had a couple phones yesterday with the same problem. I must have done exynos unlock and write cert usb about 6 or 7 times until it finally worked.

Hmmm okay. I gave up and just wiped EFS on this one but I'll do that for the next one. Thanks
