Finally, I am happy to announce the result of the solutions provide by Alray
First and foremost, my phone has been saved! This is thanks to Alray's Guru reset method proposed in post 2
and MotoXoom for the idea of using a OTG cable mentioned in post 3
For those who may be facing a similar issue, this is what I did;
The Guru Reset method is very easy if the instruction on the video is follows keenly. Since my pc could not find my phone, I when on to buy an OTG flash drive from Conrad Berlin, also available on ebay.
Initially the flash was not recognised, I then formatted with fat32 and plung-in again to the phone. Voila! it worked. First of all hit on mount and click on usb otg , then click back and hit on install. The rest of the instruction can then be seen on the video on post 2 from Alray.
It is also worth mentioning that at the end of the installation Team win recovery should be reinstall as was deleted be the Guru reset software.
However, I still need further help on how to remove the “ Tampered” on the bootloader screen as well as how to get S-Off. I do not know how to go about this, since I do not have the Token-ID. Is the Token ID not necessary for this? I will appreciate further help. Once again thank you Alray.
N.B.: I still find it difficult to quote a post directly, how is this done?
Since over an hour I am not allow to post anymore and decided to edit the previous message in order to post a message.
