New here HELP

Hi, My friend has a droid x, and I tried to install the galaxy S theme on it for him, and it installed fine, but when I turned on the phone it would boot loop, (running stock Froyo) so I told him to wipe data/Cache, and now the phone won't get pass the galaxy s logo, what do I do?
Im also new at this so just making a suggestion. Hold the power button and home button down at the same time. A triangle with exclamation will appear. Press the search menu button. Use the volume buttons to scroll up or down. Could try wipe/factory reset if you have everything backed up or easy to reload.Once scrolled down to that option hit the camera button to perform the operation. I guess u pulled the battery first to see if that would reset? Again Im new at this and have done it myself but try at your own risk if there are no other replys.
Try that. If that doesn't work you may need to sbf your phone.

[Q] how to reset a locked phone

need your help guys
My mates just got a galaxy s and hes locked the phone with the pattern unlock screen, theres no google account registered to the phone because its brand new so there is no other option than to keep trying with the pattern unlock!
Is there a way to factory reset the phone without flashing a new rom whilst in this situation?
If not, where can i find the correct stock rom (not interested in upgrading yet) and the correct version of odin?
Thanks Craig
you can boot it into recovery when you shut down the phone and then hold volume up, home and power until the samsung galaxy s i9000 screen appears. then release the buttons, you can navigate in the menu with the volume keys and confirm with home.

[Q] Back, Menu ja Power keys not working

I was trying to get the menu key to work as app switcher (did it) and was trying to find out a way to have menu key long press act as menu. At some point the menu, back and power keys stopped working. I did have backup of the Generic.kl and I restored the original but the keys still aren't working (I've rebooted twice). Any ideas what to do other than reflash the phone and pop the knox?
EDIT: I copied the original build.prop and Generic.kl from backup and now the phone doesn't go past the first Galaxy S4 screen. It does boot to recovery when I remove sim-card but I'm not keen on losing my warranty yet so I think I have to take it to the shop :/

wow!
This is something really bad! Even download mode? you sure you press the right buttons?
what did you actually changed in wanam xposed? as far as i know wanam is more on, on theming and not tweaking.
I am pressing the right buttons volume down+ home+power, it shows the the download mode but before i can press volume up to enter it it reboots.
And what about download mode? Also keep rebooting? Are you pressing right combo
press home+volup+ power, when the logo appears release power button and keep pressed the other buttons and voila.
Once in recovery, flash Xposed-Disabler-Recovery.zip. When the first time install Xposed it creates a file in your sdcard folder called Xposed-Disabler-Recovery.zip. All you need to do is boot into recovery and flash the disabler file so Xposed will disabled and your device will be working again. Once disabled you can remove the Xposed module that cause trouble.
My dear friends i am pressing the right combo and as i said, i cant access download mode or the stock recovery. I gave the phone to samsung service and those idiots are giving all kinds of explanations saying power switch may be faulty or charging pin is faulty. i am irritated, they just want to raise my bill by changing all parts.
Take the S4 to other place to get second opinion.
Maybe a stuck power button. It's a common s4 problem. You can try knocking the phone near the power button.
You have a stuck/faulty power button. It just happens so nothing you did that caused this. Try to get it loose or replace it.
Thanks you guys. You are quite brilliant. It was the power button. Unfortunately i didn't read this before so couldn't try figiting with it. and took it to Samsung service and they replaced the power button from 6$. Working fine now. quote relieved i must say. Thanks all

HELP rooted with kingo buttons wont work now

i used kingo root to root my phone and originally encounted the back button s only works with spen issue , but about an hour later after restarting my phone and trying to unroot none of my buttons would work even using my s pen , now my power button no longer will lock my phone or bring up the restart /powerdown option, my volume buttons are unresponsive , my home button does nothing when powered on , and my back and menu buttons still dont respond , but the buttons work to do system commands , (ex:restore mode, or odin mode) so i know they dont need replacing, and phone is not in a case, idk anyone can help would be awesome
see your other post .
Please don't use very old stuff read first .
If you can get into download mode, verify the model # and flash the latest stock ROM from sammobile.com, updato.com, or Samsung-firmware.org using Odin.
