I moved from Sprint to Tmobile. I got a new HTC One from Tmobile (silver). I wanted to keep my old HTC One (black.) The plan was to unlock both SIM card slots and send my sister the new one (Tmobile didnt have any black and I prefer the black over silver.) Got an unlock code off ebay for the Tmobile silver, Sprint would not give me an unlock code for the black.
Looked at a bunch of different forum posts and followed the guide here http://forum.xda-developers.com/show....php?t=2586704
Since I have 1.29.651.7 with S-ON, I did more searching to make sure the methods would work and saw posts from others with similar situations refered back to this post. So I started with Solution 3a, got all the files, made sure phone was fully charged, etc.
Tried rumrunner and it went through the motions but did not work, got error
"ERROR: looks like device is not rooted AND lacks an unsecure kernel. SU or FU!!"
My HTC One black is rooted. Tried again, same thing.
Scrounged I dont know how many posts, somewhere along the lines I read to use a version of RUU that works with S-ON. Ran it, all was going well, progress bar was almost at the end and it stopped and it showed an ERROR RECOVERY .
Followed the onscreen instructions, When I unplug it from my computer as instructed, I get a "bootloader" screen that just has "RUU" in orange. Continued and it fails again, this time when I unplug it I get RUU "hboot Version is older!" Stuck at the black HTC screen with 4 triangles in each corner. Can not get to recovery, bootloader, anything.
