REQUIREMENTS
  • Download Flashfile
D820s_LOLLIPOP_TW (TAIWANESE FIRMWARE), Build 1.
14.709.1 - Supports Asian Languages

  • Download SP Flashtool
  • Download Pgfs

Confirmed to be working on Desire 820ts, us and ys variants


Please know that you will not be able to install any OTA for this firmware because it is not the original firmware for your device.

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

OMG! the upload has just restarted. It was at 89%.
BTW did you flash the Taiwanese or European RUU?

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)
