so when i rooted it i lost my wifi and i unrooted it and the wifi still didnt work then now im rerooting it again and it still doesent work please help btw i loved ur video ur tutorials are very clear and well said

[zedomax]

@Exia101x Wifi should work when you unroot. Why don't u try installing a new custom ROM? That will usually fix all problems.

and by the way, thanks so much for this vid bro

[zedomax]

@yono707 sure, sorry if the file is big but most ROM zip files are around that size.

I need some Help. It keeps failing on me and i dont know what. This is what it says

(ID:0/005 Can't open the serial(COM) port )

What seems to be the issue??

[zedomax]

@melissahelp Probably your drivers, try reinstalling drivers or use another computer.

I’ve since unplugged the phone and it isn’t bricked, but I’d like to unroot it. Do you have any suggestions as to what I should do?

[elementlaxer]

I rooted using your method a while ago, and everything was working fine, but then I needed to reformat my microSD, and my internal storage to connect to my computer and do some simple file transfers. Reformatting fixed those, but then when I tried to unroot my phone I was unable to do so. I followed your steps using Odin, and my phone was able to connect and tried to begin the unroot process, but after letting it run for half an hour the bar was still only a millimeter away from the start line.

does it work for samsung galaxy s2?

[nebco1]

Thanks for this video but I have one question. If I have a custom rom will this still work? Or will it screw up my phone?

[TheNXT1233]

how do you do this on mac or linux?

yo man, when i installed Clockwork Mod, then my wifi stopped working what do you think i should do?

[test12j]

Hey man thanks for the vid. I have a question. I did the root and the phone works fine, calls come in sounds is fine but i am having one problem. I have done some research on it but i cannot find the answer. Is there a reason why my wifi will not work on my phone now. The problem is that i can turn the wifi on but it does not find any wifi and then after a few seconds it turns itself off. have any idea how to fix this?
