Bootloop problem - HTC EVO 3D

Hello,
please excuse my poor english. I have a stock Evo3D which ends up in a bootloop after starting it. I have never rooted / installed a custom rom on it.
I wanted to gift my evo 3D to my little sister, after turning it on to check it i realized my batterie became too weak to start the phone so i replaced it with one i found on ebay.
Since then i coudn't boot properly.
I spend about 12 Hours to solve this problem but it just wont work regardless of what i do.
Here are some informations the bootloader shows:
***LOCKED***
SHOOTER_U PVT SHIP S-ON RL
HBOOT- 1.53.0007
RADIO- 11.25.3504.06_M
OpenDSP-v02.6.0.2226.00.0202
eMMC-boot

The first thing i tried was to reinstall a stock ROM using a RUU, this didn't work i did a couple of attempts and then realised it has a Vodafone branding, next thing was using a Vodafone RUU
it didnt work aswell, i read on another forum that it has to be a ICS RUU with Vodafone CID which appearently doesn't exist. So my next attempt was to change the CID in which i needed to unlock the bootloader.
So i went to htcdev.com and did everything step by step, i thought "man this is easy", i got to last step where i could choose if i really wanted to unlock the phone or not. I choose yes and the phone was supposed to reboot.
The problem now is it doesn't, it freezes with the red light and black screen, i cant access the bootloader unless i remove the battery and put it back in. If i do so it still is locked.
Now im out of ideas and feel bad for my sister, cause i promised to give this phone to her if she gets good grades.
If you have ANY ideas please let me know i would really appreciate it.

Is it a sort-by-lowest-price battery? if so it could be (again) a battery problem! In my experience most used batteries for evo 3d are stock ones by htc and Anker ones

Thanks for the quick reply, it was a mid priced battery with sold by a high rated seller.

I've dealt with a similar problem. Try booting into the bootloader and leave it there until the battery dies. Pull the battery for -several minutes-, then replace and plug in. Give it a while to charge, then start again with the ruu.
Edit:
Also with a similar problem, had some luck running the ruu multiple times consecutively without letting it boot all the way / rebuild the dalvik cache between flashes.
