[HTC Sensation] AKAndrew41:
One day, about 2-3 weeks ago, on my way to home, I decided to install an other ROM (5.1.1 ivanchi -> CM9). Went straight into recovery (TWRP 2.8.5 or 6) and formatted everything except microsd, everything seemed to go as planned. Then proceeded to install the ROM; it gets stuck, can't get pass the booting screen even after 20-30 minutes. Force-Reboot into recovery and receive "unable to mount /data | /system | /cache error". Tried changing fs-type of /data /cache /system to any other type, no success.

Got back home, tried installing RUU. Got stuck at 39%. every. single. time. !! Tried an older RUU, same response.

Then tried even oem lock + flash recovery_signed.img + boot boot.img with fastboot and then RUU install. Then again with unlocked bootloader. Still no! But, I didn't tried lock + recovery signed + boot + S-On, because I am afraid not to be able to regain S-Off at this state.

Even tried a parted format, implying that one guy managed to make it work in the end. See topic here : link.

Tried doing guy's steps but after parted /dev/block/mmcblk0 I receive Error: Can't have overlapping partitions. Tried then parted /dev/block/mmcblk0p23 (userdata), it works, and if I try mkfs/rm on partition 1, it says it's in use (p23p1 ...).

Output:

~ # parted /dev/block/mmcblk0p23

I can format my /data /system /cache one at the time, after doing reboot recovery and that's only in CWM 6.0.1.2. But this CWM isn't able to install ROMs somehow, wether it gets stuck of just plain fails. So, if I want to install a ROM, after the format, I have to install 4Ext (latest) recovery and do it there. Install everything from recovery, boot, sign in for GApps etc etc and while trying to install apps from Google Play, after about 4 to 6 apps, it gives a black screen, leaving no option but remove battery and reboot. Do that and get stuck on bootsplash / bootscreen. Everytime!

If then I try formatting paritions using 4Ext most of the time it fails, making them unmountable again after all.

Tried everything mentioned running PG58IMG with firmware 3.33, Hboot 1.27.1100, worldwide english (.104.). Tried fashing rom.zip as the PG58IMG.zip from fastboot in rebootRUU (gets stuck at [RUU]WP,dzdata,0) and now even from sdCard (gets stuck at [6] USERDATA).

I dug furthermore into bricked Sensation, seeing a QHSUSB brickbug (thread). It is refeered to be a bootloader brickbug; problem which I am not facing right now. Eventho, followed OP's instruction my freshly installed Ubuntu 14.04 can't detect my HTC. Also did some of the YouTube instructions, connecting sdcard's plate with lower pin from the back (trolled?!) (video), yet nothing.

Out of disperation, asked hinxnz and rzr86, and both of you adviced me to try thread 1 or 2 (relying on sdCard as primary/sec partitions). Good advices but I don't consider this be the best solution for this problem; STILL HAVE HOPE MAKING INTERNAL SD TO WORK! :d

ASK ME ANYTHING REGARDING MY PROBLEM! Will post every bit of information you consider relevant.

PLEASE HELP!
