Octopus box · 09-21-2016, 13:48

You can try to root the phone with CF Auto Root.

enigcreator · 09-22-2016, 10:15

Will this method work with the new security if I use octopus v 2.3.6

Octopus box · 09-22-2016, 10:42

Samsung closed "hole" in latest firmwares. If your phone has one of the latest firmwares - You might need to downgrade it (write older by release date firmware).

enigcreator · 09-22-2016, 10:46

EPF1 can not be downgraded. Phone is updated to PH2 so, there's now way I can go back to 5.1.1 or even 6.0.1 (first build).
I am stuck at EPH2. What's the solution? Imei is : 3500000000006. Baseband is OK. SN is OK. DRK is damaged, need to reinstall it.

movicel · 10-12-2016, 05:06
