Problems with rooted samsung galaxy S2?

[tuhmaytow]

So I had my samsung galaxy s2 (at&t version) rooted and I installed cyanogenmod. At first everyting was ok, but then i decided to switch to miui rom then weird things started to happen with my phone.

1.) everytime i make a call it goes through, but I dont hear the person on the other line and vice versa.
2.) same thing with my voicemail. i dont hear anything.
3.) my back and search button wont work.

Since i couldnt seem to find out whats wrong, I'm thinking of unrooting my phone. So, any help would be really appreciated. Thank You!

Rooting is not the problem.

First off, you need to use more stable ROMs. CM and MIUI are ported over from the international i9100 and therefore are not going to work as well for you device as a ROM made from an i777 base.

Also, when switching from CM to MIUI (and whenever switching from ROM to ROM) you should factory reset and wipe all data via Clockwork Recovery before installing the new ROM.

I recommend trying Binnacle or UnNamed ROMs for stability and smoothness.

I actually unrooted my phone in hopes of getting it back to normal, but it didn't work. Now I'm stuck with an unrooted phone that couldn't receive/make a phone call. What can I do?

You installed a version of MIUI that was meant for the i9100 international GS2, hence the loss of voice call functionality and the button issue.

Return to stock and reroot by following the links in ricktat's post.

Then, if you want to install the i777 version, go to: {rom} {miui 2.2.3} {2.3.7} {2-8-2012}

So I have to root my phone again to be able to fix this situation? Is that what you're trying to say? --Lawrence of a labia.

I hope that you have made a backup of the original stock Samsung ROM. Always the first step before you begin your decent into the other ROMs.

In case you have, you can then either restore that ROM and stick with it or try installing another. But yes, first step, go back to stock.

Sorry for asking too many questions, but im new to this. So what you mean by stock ROM is the unrooted version, right? Because my phone is already unrooted and so, what do i have to do?
