Thanks for the great tutorial.
I have read through the entire thread and confident of handling bootloop.
My dad bought a htc desire 510 on eBay india which ran out of storage. I am trying to install link2sd to increase internal storage. However I am new to htc devices in terms of flashing rooting etc. I have enclosed a screen shot of hboot page. Please advise if I should go ahead as detailed in OP.
Regards
Arun
