First, my G2X will run the lg screen for about 5 seconds then the screen just keeps flashing. Tried to master reboot and the screen wit the little android guy jumping out of the box appears but soon disappears to a blank screen. I've tried to NVFlash but it won't work. I'll hold down the power and volume down button but it just keeps looping over and over again at the lg screen and my computer won't recognize it at all. I done countless hours of research but I really need help. Maybe I'm just dumb or something but I just need help. I can't return to tmobile because the screen cracked like a week ago thus voiding my warranty.
I'm guessing that you tried to root your phone using oneclick? Try nvflash again! Make sure you install the apx drivers correctly. It should work. Did you try to root the phone or was it rooted already?

I had it rooted and a buddy of mine was gonna install a custom rom on my phone for me and he just fake flashed it using cwm app and before i even realized what he was doing, BOOM he went to install the rom using the app and my phone won't get past the LG screen. The apx drivers won't install because my computer won't detect an apx device
Ahh I see. When you first rooted did you backup your rom? Can you boot into stock recovery? Hold power and volume down until you see the little guy with white box?

Well I'll try and the Android guy comes up but after 5 seconds the screen blanks out and just
flashes

Try this, the apx drivers are there
Try flashing nvflash again. This phone can't be bricked so there is a way.

Send it back for repair. All your data is gone though, hope you have backup.

How about the basics:
Pull the battery, charge it for an hour or so... boot in either recovery or boot loader screen instead of just powering up.
If u get one of the above screens then ur fine.
If none of that works, then follow the link from previous post
Good luck

I've been having a bit of a hard time with a friend's Skyrocket tonight. I flashed CM9 for her before, and it seems to work well. In the past two to three weeks, though, she tells me that her phone's been randomly turning off. Tonight, I finally decided to install CM10 on the Skyrocket, thinking that this would fix the issue. I installed it through CWM like normal (I've flashed many a ROM, so I couldn't have messed up this process).
With everything installed, I reboot through CWM. The issue is, the phone just goes black. After pulling the battery and trying to boot again, I see the Samsung logo, followed by a black screen. The phone sort of pulsates for a bit at this point, giving me a short vibration here and there, before finally stopping. Attempting to get into recovery doesn't work either. I also, due to me not being used to the download mode feature (I personally have a Galaxy Nexus), accidentally tried to start it by holding the power and volume buttons (rather than holding volume and plugging the phone in, not touching power). The yellow triangle would show up very briefly, and then the phone shuts off.
When getting into download mode the proper way, I was able to get into Odin and flash CWM again. At this point, I should definitely be able to get into Recovery. But alas, I cannot... Same issues as before. At this point, it's revealed to me that, after the random shutoffs that my friend had been experiencing, she would sometimes also have trouble turning the phone back on. Noticing a trend?
I'd like to know what you guys think: Is this a software issue, or is it a hardware issue? For the former, what do you guys recommend so the phone could boot normally again? And for the latter, well... I don't suppose there are any easy hardware fixes I could try?
If you pull the battery and reinsert does the phone start on its own with no button pushes? If so... Stuck power button.

Nope, not at all. I need to press the power button for it to start.
It'd flash back to stock with Odin and then go from there.

I'm embarrassed to say that I didn't try flashing to stock because I figured it would work, but somehow, it did. I still feel that there's something wrong with the power button, and I'll be doing some more testing, but for now, everything's okay. Thanks for your help.
I bet you can reflash cm10 and it'll work fine. Just do a factory reset and the wipes and you'll be fine.

Wipe ALL the things, then Odin back to stock and reinstall. I'd bet that solves it

Recently my power button took a crap on me, and about the same time I noticed j cannot boit into recovery. I've tried multiple different ways, and every time it just boot loops. Shows me the Samsung logo then a black screen and repeats forever. The only way I can get out of the loop is to pull battery and enter download mode then reboot. I've tried reinstalling the newest recovery again also. Anyone have any bright ideas? I can't wipe anything or install anything new, and I'm getting frustrated. :banghead:
Thank you ahead of time

Load goo.im from the market, flash twrp, then use the app to reboot to recovery?
You can use Quick Boot app, which lets you go to recovery using single click shortcut/widget

"Adb reboot recovery" from your computer or go into terminal in your phone and "su" then "reboot recovery"

Which recovery are you actively using (or trying to)? If its cwm, are you sure you got the right one for our phone? Download ROM manager and let it flash the correct cwm and then try rebooting if that still doesn't work odin the phone to stock, reroot and attempt again

I sent my GS3 in with the same problem. The phone power button started to do crazy things and would not stay in download mode or in recovery mode long enough to flash anything. They are sending it back fixed today. Samsung knows about the motherboard going bad on these devices but they wont tell you about it.

How long of a turn around was it? I think that is the only solution. Also, did you deal with samsung directly? What did you tell them?
Sent from my SCH-I535 using Tapatalk 4 Beta
Yup called them directly. I told them that it was rooted but had a hardware problem. They told me that I can send it in since it was still under manufacturers warranty and they would tell me if it could be fixed. Sent it in on May 28th. Just got email that they are sending it back fixed.

Hmm awesome. I'm not sure if mine is still under warranty but ima call tomo. Thanks

Wish I saw this earlier. But the easiest way to boot into recovery without a power button is using terminal emulator.
Type in
Su
Reboot recovery
Same can be done for download mode.
Edit: nevermind, this was already mentioned.

so i tried to revert back to stock last night using odin and something went terribly wrong. still believe it is due to my power button. i got one section as failed and one as passed in odin. the phone shut off at the end and said it was rebooting, but it never did. eventually i unplugged it and tried to get it on with no luck. if i pull the battery and reinsert it, the phone vibrates, and i get a screen that says "Samsung, custom" with and unlocked pad lock. i have never seen this screen before. i also can only get to download mode for about 2-3 seconds before the screen goes black again. So i cannot retry the process, i now have a brick. Anyone have any suggestions? i was going to send it back to samsung today, but i don't believe they will touch it in this state.
reading up on hard bricks, and mine doesn't seem to be quite that since i can get into download mode. It just doesn't stay there, the screen turns off after a few seconds. obviously not long enough to odin. any help would be GREATLY appreciated. i now have no phone... this shall be interesting with the lady friend :laugh:

As long as you get into download mode you're still ok. Send it into samsung and tell them your issue with the power button. They will fix your hardware issue and will load the stock rom back onto your phone.
I don't think they care as long as your phone isn't hard bricked. I'm sure they use odin anyways to update every phone that comes out of their service center.
Can anyone confirm this is correct?

I believe koush decided to throw away the fix permissions button in CWM because he said it was largely placebo effect and had no real purpose anymore.

so do you know if external mics work on this Rom?
Ok guys i have flashed near every rom this phone has ever had and never ran into a bootloop problem. So i had CH 10.2 on my phone for 2 days with no hiccups. Then today after letting my phone die completely "battery death" i pluged it in and now it keeps bootlooping and i cant get it into recovery if i hold down volume down + power it loops at the galaxy s 4g starting screen. If i let it go of the power button at the correct time it just bootloops. anyone have any ideas?

Battery Pull. Hold Vol Up + Vol Down + Power. Whenever The Samsung Galaxy S 4G Splash Screen Comes On, Let Go Of The Power Button And Keep The Volume Buttons Held Down. Should Take You To Recovery
Sent from my SGH-T959V using xda premium
OMG YES!!! I have no idea what i did but i pressed the combo when i plugged it into my computer and it looped the battery screen twice then went straight into CWM recovery did not go through the splash screen like a normal CWM recovery start but whatever i got to remove the rom and flash the new Slim Rom . Anyone have any idea what could have caused this just so i know what to or what not to do in the future ?

To get to CWM recovery on this ROM, simply download 'Quick Boot' application and use it to get to recovery. It works.
Apex launcher crashes as well. I think issue is ROM related. Also, ROM is very heavy, I couldn't find why.
Edit: ROM is snappier after using CM performance features and letting cache do its work.

I got through the splash screen on 1st try.
You should check if you worked according to ROM instructions.
I usually always format system as well as wipe everything twice before flashing any new ROM.
I was referring to :
1. the lack of recovery button on power menu.
2. The inability to use hardware keys to get to recovery after flashing this ROM.
Heimdall One-click (in download mode) and try again.
You're right - I missed that option in developer features - it's called 'advanced reboot options'.
I'd suggest you get to download mode - one click heimdall and reflash this ROM after dowble wiping dalvik, cache, and format system.
I've flashed numerous ROMS to my phone before but have never ran into a problem like this.
-I went back to stock
-flashed CM7, as recommended from the OP
-downloaded and flashed CM10.2 but it gets stuck around 75%
I've been on this thread, and the rom thread as well as waiting a bit, hoping to find a solution or it figures itself out. Nothing! Is it unsafe to pull my battery when its at 'Installing update' (75%) for an extended period of time?
Also, i am on CWM 5.0.2.8
Thanks
I flashed it from ICS (Ultragen) and had no problem.
You can try that as well.
