When I use tools like this I follow instructions by the root maker or go to XDA forums. I have never found Android support for this here.
I don't know if I can root again my j5. Yesterday I installed a custom recovery (twrp) in j5 2015 (v 6.0.1 marshmallow) and root my device successfully. Then by mistake I untick oem unlock and restart my phone. Then I got a message saying " Custom binary locked by frp or fap don't remember exactly. I installed Samsung kies 3, enter download mode and flash new firmware successfully. Today I was about to install custom recovery again and when I went into download mode, I noticed something different. Warranty void 0x1 (2) I google it but in every forum, every post it showing that have in front know but in my phone its just saying "warranty void 0x1 (2)" anyway my question is if I can install again custom recovery and root without bricking my device because of this message. Please answer soon.
