[One (M7) Q&A, Help & Troubleshooting] butcher211:
Hello,

I have a really big problem. Since two days I cant start my device anymore. I tell you anything:

I had Android Revolution HD with Sense. But since the NSA/PRISM scandal i stopped using Gmail. So I used an other more save hoster for mails, contacts, calendar entries and tasks: Posteo

To sync Posteo with my Android device, I had to install following apps:

CardDAV-Sync beta - https://play.google.com/store/apps/details?id=org.dmfs.carddav.Sync

CalDAV-Sync beta - https://play.google.com/store/apps/details?id=org.dmfs.caldav.lib

Than I encrypted my completely phone storage with the ingame android encryption feature. So with every boot of android I had to write an password and after that the OS started with my settings, contacts, and andything.

So, I was a very happy guy until I found out this bug: http://dmfs.org/wiki/index.php?title=HTC_Sense_issue

That was the end of my happiness. I started trying around to create new contacts and found a way just to create new contacts but I still couldnt EDIT my contacts. So I had to edit them online in the webinterface of Posteo. After 3-4 weeks of doing this I thought: "Am I stupid?????"

The answer was "No" I thought and I did write an email to the HTC support and their answer was:

"Hallo ***** *****,

thank you for your message.

I am sorry, that your are disappointed about our Smartphone. Unfortunately the CardDAV Using is not possible at the moment.

But we inform our technical engineering team yet and they now, that this is a feature, which our customers want to use.

I would ask you for some patience."

So..... well.... just to know for you: HTC is the next brand that I will boycott! :good: :fingers-crossed:

Back to square one: So I had the idea to install the Google Edition which is I think better because of no BlinkFeed no extras, JUST ANDROID.

Than I backed up my hole SD card (you know that procedere), I made TitaniumBackups (you know that procedere too), I downloaded the Android Revolution HD Google Edition because of the optimizations, copied the file to my sd card and rebooted into... yeah, recovery! ;)

In the recovery I clicked on all wipe buttons and wanted to "choose" the zip from my sdcard but then it didnt work. What did I wrong??? Did I format the storage too that there are no files and thats the reason why I cant see files!?!?!? No.

It is the encryption!

I went into the Mount/ Storage menu and tried to format everything: I cant format my sdexternal!

No mount/unmount too and I thought: sh** :)

So I started my device and thought firstly that my phone is yet bricked but no: He asked me for my password to decrypt the device. (Wow! Google or HTC or whatever you have a good encryption :) )

So I was in my system and everything worked how it should. But my problem was the encryption. I went into settings, searched the storage and security things and developer things for "DEACTIVATE/REMOVE ENCRYPTION PERMANENTLY" but no... there was nothing!

So I thought; Hey, I cant factory reset within the OS and I did it. Then I went again into recovery and i formated this time everything but sdexternal wasnt formattable. Encryption still exists. :/

What should I do now?

Here the text of my bootloader:

TAMPERED

RELOCKED (I did relocked it after installing stock recovery because im very very scared that i can never use this brand new (1 month) smartphone anymore :/)

It is a normal HTC One (international) which I bought here in Berlin, Germany.

Oh and I didnt tell you that I had so much problems with windows 8.1.

So I installed Windows 7 64-Bit on my Lenovo X230 and fastboot works now without problems (I thought).

I can oem rebootRUU but when I want to flash within this mode it says "waiting for device" :/

yesterday it worked but there was a 99 FAILS problem. since then it doesnt work anymore.

Please give my any tips which you can do! :crying::crying::crying::crying::crying::crying::crying:

Thank you for reading!
