Boot loop! Help!



Hi,

A few weeks ago, I found my wife's HTC One SV (k2ul, Europe, LTE) that was forgotten in a drawer for a few months. I wanted to use it as a secondary phone and began to process to upgrade it. I got it running on Venom 1.5, running Android 4.2.2. It worked OK a few days then I had a few strange reboots. I re-flashed Venom 1.5, strange reboots again. Re-flashed it once again and now I'm stuck in a boot loop. It boots, shows the HTC green logo, black screen, vibrates, HTC green logo, rinse and repeat.
The installed recovery was TWRP 2.7.0.1, but it had this annoying bug that when the USB cable was plugged, the touchscreen didn't work. I found TWRP 2.8.7.1-k2u/ul which fixed this issue.
With both TWRP versions, I tried three ROMS:
ViperSV_1.5.0.zip (4.2.2)
k2ul_4.2.2_3.11.401.1_stock_odexed_v3.zip (4.2.2)
Saturn+III+v1.20 (4.1.2)
I also tried sideloading them.
I can't get out of this boot loop (tried full wipes, partial wipes, etc.). I tried with a SD card, without SD card, with a SIM card, without a SIM card. Boot loop. I read each and every topics about SV boot loops. Nothing worked.
Do anyone here have an idea of something I could try? Here is what my bootloader displays:


Code:


*** TAMPERED ***
*** UNLOCKED ***
K2_UL PVT SHIP S-ON RL
HBOOT-2.00.0000
RADIO-1.18.40a.00.05
OpenDSP-v13.2.0268.0620
eMMC-boot

HBOOT

<VOL UP> to previous item
<VOL DOWN> to next item
<POWER> to slect item

FASTBOOT
RECOVERY
FACTORY RESET
CLEAR STORAGE
SIMLOCK

Finally, let me explain why I tampered and unlocked my wife's phone: more than one year ago, HTC released 4.2.2, featuring a bastardized Sense 5.0. She applied the update and got in a rage because she hated it. She asked me to give her her beloved Sense 4 back, but the downgrade was officially not possible. Completely unfamiliar with HTC devices (I only had Nexuses devices at the time), I unlocked the phone and downgraded it to Android 4.1.2 running Sense 4. She then used the phone a few months without any problem and finally got an Xperia Z1, forgetting to One SV in a drawer. I'm not an expert with HTC phones, but I know my way through XDA and it's the first time that I can't get out of a softbrick.

[TL;DR] Tampered and unlocked, S-On HTC One SV k2ul boot loops, I tried everything to unbrick it, I'll try anything you suggest.
