Hey Guys! Finally I rooted my Wildfire S... it was a hell of the day! I am really impressed by your patience and dedication in helping people like me, newbies and dummies in this field

. A big thank you to all of you!
Inshallah, I hope it wont get me troubles, but will see. I think the hardest part is gone

.
Let me share with you my steps:
Characteristics: Wildfire S A510e, Marvel, Locked, S-ON, Android 2.3.5, Kernel 2.26.401.3, H-BOOT-1.09.0099.
1. Did not update the bootloader. Didn't need to.
2. Followed the third step, unlocked the bootloader at htcdev.com.
3. Had issues with the fourth step, supertool v3 didn't work, superuser didn't had the su bin file, supersu also didn't work. Had errors like previous guys, the red triangle too, etc.
4. Took the 5A and 5B step but using the files from this guy: user in youtube: aphroditelikesme, title: (HD) How to Root the HTC Wildfire S (GSM) - Cursed4Eva. (in the description). As a new user on this forum, yet not allowed to post links...
5. Last step was the square above the step 5th and it went perfectly, without the fact that it didn't back up from CWM cause it couldn't see the sd ext... same issue that was previously encountered by others, but that's not a big deal.
Now the phone is rooted. Superuser is doing his job. Link2sd is moving all the apps to SD.
I didn't install a custom ROM, as I like the HTC sense, cause of it's design and efficiency with this phone...
A whole day of headaches, researches, readings, outdated versions vs new versions, but it worth it! I was so happy that I even washed my dishes at 1am

.
Thanks again guys, and all the best!
