make sure you delete folder that are created on your phone by . ie titanium backup ex. I did a factory reset after this to include usb format and it still left stuff on there.

[martinr0120]

If I root my phone should it slow down my data speeds? Because mine is really slow! Thanks.

[zedomax]

@martinr0120 No, probably not root related, try installing a custom ROM, should make everything faster.

[prwalia10]

@zedomax Well i just did this and i guess its been unrooted but when it was rooted the ROM dev had a custom screen so it shows that when it boots up and its not going away...idk what to do i have to send this phone back soon :( can someone help me pleaseeeeeeeeeeeee

[m1sterfan]

[shinzantetsu]

[DarkskinWhiteBoi]

Thank you uploader !!!

[jcesar085]

please help the usb connection doesnt work on my phone it shows the usb connection pop in the top bar then turns off. That is reason i want to reroot it.

[zedomax]

@jcesar085 not sure, did u try installing another ROM, it that happens then it might just be broken USB hardware.

[Lanfire49]

Omg I did everything, and now I can not power on my phone. I am scared. Please help me :(

[SuperLink2008]

hey Zedomax, can you tell me if i unroot my phone using your method will get the ota update to 2.3.6 for the wifi calling. thank you

[medina191]

easiest way ever you are a lifesaver thank you so much

[s2raaron93]

I go to the website to retrieve the .zip and there isn't a link for me to click to download it.

[archamrmorsy]

I had BeastMOD II 4.2 installed which has Synergy 0.10 included in it and when I unrooted my T989 it showed the Synergy Picture at the beginning. Any way to completely put back the phone to complete stock. please help as I need to swap my phone due to screen issues. Thanks a lot for you helpful topics.

[zedomax]

@archamrmorsy Hmmm that's weird, that probably means you still have synergy kernel, try flashing stock kernel (via ODIN or CWM) over it.

[archamrmorsy]

@zedomax I did and now it is back to normal but another thing popped up. When in download mode it says that the binary is "Custom" not "Samsung Official"!!! and the count is up to 2! Shouldn't it say that it is Samsung official since it is the stock kernerl. BTW thanks for the quick reply :D

[zedomax]

@archamrmorsy You need to make a USB Jig or buy one on Amazon, that will reset the counter. I have a video on how to make a USB Jig, search my channel.

[extricker]

@zedomax how do you flash the stock kernel, what file do u need to do that, i have the same problem here i tried everything but not working,

[azianxkidd]

my phone will not start. goes to samsung screen and turns off and never kicks back on. i can get into the stock cwm only. need some help please...

[le14]

Just did this and I am back to stock, but I need to return this to tmobile due to the phone having some issues.

I still have the synergy kernel gray screen upon bootup, anyway to get this off the phone? I am unrooted now though since I did this process.

I looked at the other threads, but I'm not sure what to do since I am not rooted anymore. Any help anyone? thanks

[jimmyantonio77]

Does it work on the Telus Version?

[Tkingnight]

thank you!

[roseguera100]

hey zedomax if you unroot your samsung s2 can you get ics....or i guess my question is can you get ics while unrooted or rooted over the air updates yes or not...thanks man you been a great help to all us new

[roseguera100]

hey zedomax when you unroot tmobile s2 back to stock rom can you get ota updates by samsung or you can't cause the phone was once rooted..thanks

[Infernaped]

Can you help me? I rooted my S2 then flashed the Bomb ROM on your site and reset to the factory with the ROM also on your site. The problem is the Synergy Kernel keeps appearing and I would like the stock boot animation back. How can I do that?

[Tawfiq79]

Thanx for the video. So should I unroot every time I want to update any rom. For example, I have the Juggernaut 2.5 and I want to update to 2.6. Should I unroot or not? If not how can update the rom

[afklaj]

Hey dude thanks alot! but i have a question can batista rom be downloaded on the T-mobile Galaxy s2?

- Thanks

[zedomax]

@afklaj please dont flash batista rom on Tmo gs2 as its for international version only!

[afklaj]

@zedomax Thanks dude, so are you guys going to try to take something of that sort out for the U.S. versions??

[gulseth77]

hey, does this work for the "Telus (Canadian carrier) galaxy s2 x"??

[w1a9s9i7m]

Does it alsow work for the original galaxy s2??

[italy1999]

Great advice and yes it works!!

I have noticed that the spell corection on the samsung keyboard does not work and all the setting are selected. It works on the Swype keyboard though. Does this happen with yours??

If not, can you help me fix it?

[zedomax]

@italy1999 not sure, I rather actually not have the spell correction as it interferes with my typing. But I will look into it.

[kingofcalhoun]

Awesome! Thanks for this. Looking forward took trying your  rom

[scuzzbag87]

Hahaha shameless promotion nice

[LadiesMan660]

Oh BTW I rooted Samsung Galaxy S2 international by follow your video, detail on the webpage. Very Clear. How do Overclock SGS2 orginal?

[zedomax]

[LadiesMan660]

@zedomax Thanks... Is this Bastista rom "overclocked"? Or do I have to overclock after install this rom? Or BTW, I installed tegrak overlock app but is not overclock high enough.
