[Help] Xperia Arc Issues

[#1]

Hallo i have an xperia Arc LT15i, few days ago i updated it manualy with flash tool from gb to 4.0.4.

Using this site  http://talk.sonymobile.com/thread/38251 and this guide http://www.youtube.com/watch?v=i9VnDu60smE&feature=player_embedded

I did it fine, i rooted my phone also and i found some problems..

1)3D is not working corectly... i have big fps issues in all my games... and when i tryed to benchmark my phone, when the program reach the 3d test part the test ended abnormally.

2)Facebook, any time i try to update a status the facebook aplication terminates and i get a message to report the problem or close it..

3)Multi Tasking: when i have some programs on and i try to do some staff my programs are getting terminated..

4)Menu doesnt work smoothly: when i enter my menu and change tabs i have a delay like 1.2 seconds

5)3G/H problems, when i am on internet via 3g or H it changes the signal to 3g and after 5 seconds to H leading my internet to restart.

6)Dial Up delay, like 3 seconds (even though i found out all people got this problem)

Okay i know 4.0.4 is a bit heavier but my phone is working like stupid, i have lag in the 90% of the phone proccesses..

More Phone Details:

Kernel Version: 2.6.32.9-perf Build@user@buildHost#1

Build Number: 4.1.B.0.431

A.V : 4.0.4

I would apriciate any help if possible, otherwise i have to downgrade my phone..

1 more question, from the time i rooted and flash my tool my software is now custom (not official) so i cant update via sony pc companion, is there any way i can format my phone so i can turn it back or something??

Thanks In Advance

How did you root your phone?

Have you tried "repair your phone" with PC companion?

I rooted my phone via doomlord, whats more i bought another xperia arc yesterday, and i didint rooted this one, and made it it 4.0.4 via update service and i have the same problems, so its not the custom kernel or custom flash i  made

[MarlonUk1]

although you have flashed, you can actually still used Sony Update Service and PC Companion to repair your phone, onec you do it though, the root will be gone . so you have to root again

Okay but my other arc that is 4.0.4 with no flash has the same problems 😕 so i think its android"s problem and not the kernel or the boot,

Whats more my phone is supercharged too, if i remove my root by repairing will the supercharged removed as well?

[Nabeel]

Yes the supercharger would be removed too
