My phone is currently sitting with a "S/W upgrade" screen after a series of stupid events. I flashed recovery using ROM Manager before I had read that it fake flashed. I rebooted into recovery and installed CM7 nightly. Rebooted and it's stuck in a boot loop. So I finally see all the warnings against that so I figure I need to get a real recovery so I use the awesome guide from TGA_Gunnman. I follow all the instructions and it appears from the log on my PC that the CM recovery flashed successfully. I pull the cord, reinsert my battery and my phone just sits in the S/W upgrade screen. It's been like that for 30 minutes now.
What do I do?
I thought I'd done something wrong with my G2x because that happened to me too. Remove your battery and USB. Then insert your battery again. When you turn it on, make sure to hold both the power button and the volume down button until you see text that says android. If you, like me, thought you just had to hold the volume down and tap the power button (like my Nexus One), that might be your issue.

just disconnect usb, and go to recovery Power+vol down...
.....and congrats !
yep, I thought I bricked it too.. When you were done at the green screen where it said press any button, thats where you press whatever you want and then unplug the cord. Then, put the battery back in and hold down vol then power, don't let go until "android" pops up.. You did it man, just missing your last step..
Moved to proper forum
I can get to the Recovery screen, but I cant select any of the options....volume lets me scroll, but cant find anything to select any of the options....kinda new at this
power button to 'action' your selection... at least it works for me.

The "S/W upgrade" stays on, that's normal. See if your terminal window has completed whatever stuff it is doing. If you get a completed message, you are good to go and can safely pull out the USB chord even if your phone still says "S/W upgrade". Put back your battery and hold Power+Vol DOWN button and see if you get into cmw recovery.
so im trying to fix my friends phone and this is weird..
im able to go to cwm, wipe it all and flash a new rom.. it flashess successfully but when i reboot it goes back to the s/w update screen..it happens with any rom i flash.. its been sitting there for a while.. how long should i wait?
Once you flash the ROM you shouldn't be getting that screen...Does your friend has the G2x or 2x and which ROM did you flash?
Sounds like you screwed up the boot image. Go into APX mode again and reflash the recovery package making sure it completes, you hit a key to close the terminal window, and you hold the volume buttons the entire time. Then go into recovery and factory reset and clear the Dalvik cache. Then if you still get the S/W update screen you are going to need to go to the thread about fixing bricked phones and use the KDZ method to reflash the entire GB OTA package. There is also a new method to reinstall the entire OTA package using NVFlash but you have to hold the volume buttons down for about ten to fifteen minutes while everything flashes.
I rooted my LG P 350 with Gingerbreak, and i set up CyanogenMode 7.2. Phone worked whole day, but when i connected phone to PC it was in debugging mode, so i try to disable it and my phone just showed me a black screen. No i can't start Android, all I get is Linux penguin in the top left corner. How can i fix it? Thank you.
Have you tried rebooting from recovery. Simply pull back your battery and put it back again, and press the power, call button and the volume down button to start your ph in recovery mode. Just select reboot button from there. If it doesn't work, you may need to reflash your cm rom.

So I've been using CM10 nightlies for months without a problem, and today I installed the newest nightly. The phone now boots, showing the HTC screen, and then goes black. It is responsive to pushing the power button. but all that happens is the backlight turns on, but the screen is still blank. I've read about problems associated with the new 3.17 update, but to my knowledge I have not installed this update. So what can I do? I'm hoping just reverting to the previous nightly can solve this problem?
Hold the power button for about 30 seconds.. And everytime you hold the power button does it boot up to the HTC screen or does it go blank... It could be your LCD blunked out on you but I doubt it....
No, when I do this the HTC screen comes up and then it just goes to black. I don't get the CM spinny wheel or anything, but the screen is definitely still fine.
Hold volume down and power than get to bootloader
Hold volume down and power together while the phone is booting. The hardware keys will blink 5 times then the phone will go off. Let Go of volume down and power. Wait 5 seconds press volume down and power. It will go into bootloader. Select recovery, you'll be in recovery. Flash whatever, brick your phone as you can't read enough to figure out a: don't post twice and b: how to get into the bootloader of the phone you rooted. I'm shocked you got this far.

Thanks so much for being so helpful! I'm not an idiot. I've been installing these nightlies for months without a problem, and this just suddenly arose with the latest one. I tried flashing back to the older nightly, but now the phone boots and is just stuck on the spinning CM animation.

If it gets stuck on the boot logo, then you probably need to manually flash the kernal which should be included in the roms zip/rar file.
Yep, reinstalling kernel and new nightly did the trick. And in the process I'm now running 4.2!
like title says, when I try to enter download mode it just goes black again like it's booting and nothing happens. I thought it might be a bad power button but when I went back to stock with Odin a few months ago it was working fine (power button problem but could still get to download).. so I think it might have been the rom (carbon 4.3)
I've been running Carbonrom 4.3 nightlies and they've been ok but then the power button problem started coming back up, and last night when I went back to stock again it was fine, the power button worked fine until I flashed a nightly I knew would work back from Sept. Now I can boot up the phone, the power button does NOT work, and when I try to reboot to recovery or download mode it just goes black and nothing happens like it's restarting. Taking the battery out and plugging to my PC does nothing, the red notification light comes on and then goes off.. Odin never sees it
Only thing I know to do now is let the batter drain all the way down and see what happens, but for now I can't even Odin back to stock. Any ideas at all?
little bit of an update: I was able to finally get into download mode by removing the plastic power button, booting normally and shutting it down completely, and then using the power-down-home combo.... after going back to stock via Odin, the power button works perfectly.. gonna reroot and try to update to 4.3 gradually
after 4 days of perfectly running Liquidsmooth rom 2.37 (4.3.1) the power button is acting up again so I removed the button completely again and just won't use it, seems to be working at the moment
if anyone knows a way to fix this besides taking it in for repair please post
Edit: PROBLEM SOLVED! However I'll keep this up just in case anyone runs into a similar issue, I'll go ahead and quote the post that brought my tablet to life. As simple as it may be, it helped!

You can't really hold them together sometimes, I don't know why.

Okay, so in case I'm missing something, I'll keep it quick and say my tablet (WiFI version) wont boot to the system, and no button combo will boot it into the bootloader. It goes straight to the nvidia screen no matter what, and won't get past the boot animation.
In case that doesn't cover it, and more info is needed, I'll give the complete rundown of all that happened.
I just got my tablet a few days ago, however I immedietly unlocked the bootloader, and rooted it, and was fine with that for a while. Eventually I got sick of Lollipop due to lack of support for some Xposed modules and other apps that didn't support 5.0. So I decided to boot into recovery and flash THIS CarbonROM. But it didn't boot past the CarbonROM logo, so I forced a shutdown and booted into recovery (vol down + power) and figured I had to flash the KitKat OTA, then the ROM. So I flashed THIS OTA onto my tablet in CWM, then after booting I booted back into CWM and flashed CarbonROM. It booted just fine. I then went into ES File Explorer and deleted the system apps I didn't want (calender, the stock launcher, etc.) and it worked fine. I then booted back into CWM to clear cache and Dalvik Cache, to clean up any app data that might have been left behind. After booting it stayed on the "Android is upgrading" screen for almost 20 minutes. So I decided to hard reboot it. After doing that, I'm where I am now. The tablet won't boot past the CarbonROM logo, and although I can manually power it down, no matter what I do, I can't boot it into bootloader. I have gotten to the bootloader from a powered off state plenty of times before, in fact it's my preferred method of doing so. But now it skips straight to the Nvidia screen, followed by the CarbonROM screen, and never boots.
Also, I had just flashed the ROM, and had never enabled adb debugging.
Any possible solution would be greatly appreciated, as like I said I just bought the tablet days ago.
Try connecting it to your pc, boot it up, and try running "adb reboot revovery" after it's been running for a bit

I seem to get a "error: device offline" message when I try that.
I have used adb and fastboot before this issue so I know my drivers and adb files are just fine :/
Edit: When I unplug the usb from the tablet it makes the low battery noise. I think it's booted to the system but stuck at the CarbonROM logo for some reason. I did delete the stock launcher without installing a new one...
Edit: Since I had just flashed the ROM, I had not yet gone into developer options and enabled adb debugging. I had only done it before I flashed the ROM.
