1. Incase the phone is soft bricked during this process can we go back to stock kitkat rom with stock recovery?

2. Will we be able to do OTA update incase if HTC decide to realease any OTA updates in future with this rom?

It is not just a ROM, it is a full firmware so yes you will receive OTA updates if the carrier releases them. To revert to lollipop you will have to reflash the full Kitkat firmware with SP Flash Tool here

I know what you mean

same thing happened to me uploading to mega; it's great, but not resumable it seems, unless i missed something

but if you're going to be continuing this, i can highly recommend androidfilehost.com
and use ftp for uploads (those are resumable)

 

[Mohamed Yaser]

OP, sorry for the off topic

@Mohamed Yaser

I've been uploading to afh for quite a while, i can disconnect (or get disconnected) for several days, and still resume my uploads

better check your settings and/or ftp client
