[HTC Sensation] EddyOS:
Seeing as there are FAR too many stupid people on this forum I'm going to make this REALLY simple...

*** NOTE*** - This guide assumes you are already S-OFF. If you are not (e.g. 100% stock) then you WILL have to run Revolutionary to get S-OFF before continuing

Original Sensation:

Firstly - you HAVE to be running 1.50.401.1 to use this OTA file. If you're on ANY other build then don't ask about flashing it as I WILL report you to Mods for being a dumbass.

You also have to be 100% stock (e.g. NOT rooted). If you are running a custom ROM you HAVE to use the 1.50.401.1 RUU to get back to stock but you HAVE to leave the phone S-OFF. CID can be whatever you had if you are running x.xx.401.x when you got it new but if you've flashed the RUU coming from another build then set yours to HTC__001 before starting

1. Download the 3.32.401.5 OTA file from HTC - http://fotadl.htc.com/OTA_PYRAMID_I...1.50.401.1_release_252072fll6erqo75dsziua.zip. You do NOT have to rename the file

2. Copy the file to the root of your SD card

3. Turn your phone off and turn it back on whilst holding the volume down button. If the HBOOT menu doesn'y appear then you need to turn off fast boot in the Settings>Power menu

4. Select 'Recovery' from the menu to enter the stock Recovery. If CWM loads up, stop now and flash the 1.50.401.1 RUU

5. When you get to the screen with the red ! on it, hold volume up and press power. It will say 'cant open cache/recovery/command' and then bring up the recovery menu

6. Select the option to apply an update from your SD card and then select the OTA file

7. Wait the 10 minutes or so for it to flash

8. When prompted, reboot the phone

9. You're now running stock ICS 4.0.3 with Sense 3.6

Sensation XE:

Firstly - you HAVE to be running 1.73.401.4 to use this OTA file. If you're on ANY other build then don't ask about flashing it as I WILL report you to Mods for being a dumbass.

You also have to be 100% stock (e.g. NOT rooted). If you are running a custom ROM you HAVE to use the 1.73.401.4 RUU to get back to stock but you HAVE to leave the phone S-OFF.

Now, this can't really be made ANY clearer. If you can't follow this then you should walk away now as I will not tolerate anyone asking something that is already stated above. If I have actually missed something then please PM me - do NOT post it here in this thread as it's a reference thread

*** EDIT: I've attached the stock recovery taken from the 1.50.401.1 RUU. It's the same as the XE one so will work for all users ***
