As part of this process I’d tried to ise TWRP v3.x to disable Syste, Data to be unchanged before loading the custom firmware. For some reason I was unable to complete this process. So I thought of completely follow the steps given in the original thread.
So I’d decided to downgrade TWRP to v2.8 via Mobile Uncle. The mobile was restarted as part of this process and got into Factory mode. Since then I’d followed multiple steps including back to Stock ROM. But there was no success as the mobile is not detectable via fastboot. The mobile is detected in ADB but as unauthorised. When tried with YGDP the phone was detected but it was unable to switch it to download/flash mode.
Please help me to get this issue resolved. I’m completely stuck with this issue. Thanks a ton for every one’s understanding help prompt help/suggestion/support
