Download & Install WP7.8 ROM for HTC HD2

Wow… The legendary HTC HD2 is still alive and kicking. HTC HD2 may not able to get Windows Phone 8 Apollo update. But you can enjoy WP7.8 ROM (OS version 7.10.8835.35) on HTC HD2 now. And it is fully unlocked. Of course it is loaded with other goodies like Ultrashot Root Manager, WM Device Center, USB Video, Nokia Camera Extras, Nokia Drive… Personally, I still prefer Android over Windows Phone. But there is lot of HTC HD2 owners who love Windows Phone will like to download and install this WP7.8 ROM for their HTC HD2.

WP7.8 ROM for HTC HD2

OS version 7.10.8835.35

I did not try this WP7.8 ROM for HTC HD2 personally. Besides, the download link is temporary removed at the time of writing this (no worry, it will back soon). Hopefully, my WP7 installation guide is still working for this latest Windows Phone 7.8. As usual, do get more information at XDA website. Enjoy…

  7. Hello Jayce.

    I’ve tried to transport the HTC HD2 WP 7.8 to my HD2 but seems there is a error. I’ve couple of times tried and also rom is running,but after it finished the transported rom says ΓΏou have no
    sdcard/mightly be broken or your SDcard doesn’t be recognized. I’ll be think i have to buy a other SDcard but i don’t know which SDcard i can use for my HD2. I use no a SDcard 16 GB and also i’ll tried to formatting my card (with succes),but the same error comes again (also with the WP roms 7/7.5 and 7.8). I’m now use the EVO/HD2 rom .zip and these .zip rom works perfect via AD recovery,and also other Android roms works fine (almost all) onto my phone.

    I hope you’ve the right answer(s)

    Many greets from Bertus Netherlands

      • Thanks Jayce for your answer. I’ve checked my SDcard 16GB and also these card is Kingston,but i think what is going wrong. I read a turtorial and that says “You’ve to be change your SDcard into FAT32 format”. And when this working i’ll be write back a letter.

        I wish you for now a Merry Christmas and a very lucky and good newyear (2013)
