[Q] recovering from a softbrick

So I have an lg g2x originally running gingerbread 2.3.3 and I went through this procedure -> http://forum.xda-developers.com/showthread.php?t=1259852&highlight=linux+g2x+root
Everything seemed to work as described except that the phone now will not boot. I get to the LG screen but then the buttons just blink and shuts down and tries to boot again.
I must have missed a step somewhere, though I am not sure where that might have happened. In any case, I would like to get this working or, at the very least, get the phone back and working.
I am running linux and do *not* have access to windows at all.

Which LG screen are you getting? The static one or the one with a moving green bar underneath it? Can you still boot into Clockworkmod Recovery or was that a no go? You need to give more detailed information so people can figure out at what point in the boot process your phone is rebooting.

I get that initial booting LG screen with the face and the letters LG, there is no green bar. It sits in that screen for 15 or 20 seconds then attempts to reboot. Well, thats what I assume happens. The screen goes black, the buttons along the bottom flash and then after a few seconds that white LG screen comes back and it does it all again. It never gets past that and never into CWM. I can still put it in the flash mode that allows nvflash to connect and do its thing, but thats about it.

If you have successfully nvflashed cwm. Then you should be able to get into cwm by holding volume down+power until it goes to a blueish LG screen. Then flash a rooted rom from there.
That is the easiest/safest way of rooting a g2x. If you haven't done this you can Google "nvflash g2x Linux" and find guides on how to do it.

Right, thats exactly what should happen. Unfortunately, its not what actually happens. During bootup I a can hold power + volume down all day long and get the exact same behavior. Its a bit disconcerting.

[solved]
Guys, I found the problem and figured I would post it here for future folks.
I was unable to start my phone plugged into the charge (both to the computer and to the wall). I had to have the battery in for this to get to a good place. I guess initial startup just took too much power.
So if you do this, after using the restore script. Press the power button and volume down hold both, then *put in the battery*. Thats what worked for me.
thanks!

[Q] Galaxy Nexus Boot Loop (stock)

I have an unlocked HSPA+ Galaxy Nexus imported from the UK to the US. Ordered from Negri Electronics.
It's not rooted or modded in any way.. Mainly because I don't know how to. As far as I know, it's running stock ICS.
I was using it normally, (using the fb messenger app if it makes any difference) when it suddenly rebooted by itself. The Google logo comes up, then the start up animation, and sometimes the home screen will appear but is not touch sensitive (i cannot slide it to unlock), and then it 'hangs' and the screen goes black. Repeat.
I've tried to fix this by myself and there's a video on youtube (sorry, noob here. can't post links. video is by robbidwv and title is "my galaxy nexus won't boot..") of the same problem that I have, but the posted solution doesn't work for me.
So far, I have entered Coin Mode and pressed Start. Entered Fastboot mode and gone into Recovery Mode (no options appear after that. it just starts booting up and the loop begins), and I've also tried Restart Bootloader.
I've almost given up. Now all I want is to extract my SMS, if they're still on my phone. I can't access the folders on my computer because it won't boot up and connect. Is there a way that I can extract my SMS by using DOS in either Coin Mode or Fastboot mode?
Or even better, does anyone have a solution to this boot loop problem? I'll contact Negri Electronics tomorrow and hopefully they can send me a replacement.
Please help!! Thanks

that problem just started happening with me an hour ago!!
i hate this!!
we need a solution please!

Hey guys, sorry about the issue.the major problem I see here is you wanting to retrieve your txt messages, which might be possible with a little Modding, but if yourwilling to lose them to get a working phone back, then this is what your going to have to do. Make sure your phone is completely off. Hold the 2 volume buttons and the power button together. You will get into a mode with an android Guy. Press the volume button up or down until it says reboot recovery at the top. Press the power button. It will rebootand come to a screen with an android. Hold volume up,down and power at the same time. A menu will come up. Go down to wipe data. Click it, and after it is done reboot. Your phone should work now.
If this helped you, or you simply appreciate me taking the time to write this out then please press the thanks button

Hey!
Thanks. Yeah I 'fixed' it already. I was just about to post something similar. After a while I just gave up on trying to recover my data. Good thing that Google syncs everything so the only issue would be recovering my messages, which I decided weren't worth sending it in for a repair which would probably not be able to recover anything anyway.
The thing I didn't know about was to press power + volume up WHILE on the recovery screen. I thought navigating to the recovery screen was it!
Still, this kind of sucks. I love my GNex, but I can't help but be slightly pissed seeing that my crappy iPhone 3GS never did this in the 2 years I had it. Oh well, hope it doesn't happen again!

hey guys! i also did a complete wipe on my phone and got it working again!
but i wonder why this happened in the first place?
last application i installed before the crash was double twist, i dunno why but i feel that it was the reason behind the boot loop!

Sorry for reviving this thread, but I just had this happen to me TWICE!
It happened to me first last Monday, the 23rd - the phone crashed when trying to send an email with an attachment - and went into a boot loop - Google logo would appear, no make it to the animation, and reboot....
I performed a full reset and things worked again. I didn't install all the apps I had before - figuring it must have been due to some app messing with the OS.
Well, it happened again to me yesterday! I was connecting to my bluetooth headset when the phone crashed and went into the boot loop. Full reset worked again, and I've installed even fewer apps - essentially only those that I use on a daily basis.
My phone is still on 4.0.1 and I'm hoping once 4.0.4 is pushed this may get resolved? I have a canadian GNex from Negri. I will call them again (I called the first time, but when the full reset worked I never contacted them again).
I would like to this this is a software issues, and not hardware.

I have the same problem. If you figure it out let me know.

Today my phone also entered a boot loop: [Google logo]->[black screen]->[vibration]->[Repeat]
I tried Recovery Mode, but this is what happens: (sorry for the link but I am not trusted with powerful tools such as outside links apparently, as I have not yet reached the maturity of a person with eight posts... )
dl(dot)dropbox(dot)com/u/53568097/Android.jpg
This is what I see when I navigate to Recovery Mode
For a split second I can see an image of an Android with spinning cogs in his innards, but then this little sad fellow appears. WTF is this?
EDIT:
Oh, and I'm running Android stock 4.0.2, never rooted or unlocked, Swedish. At the time when the phone started doing this, I was using Endomondo, and was about to set off on my bike when it died on me.

Stock ROM galaxy nexus bootlooping after wiping data also.
Hi,
My GNex went into a bootloop so i searched xda and found that factory reseting would be helping my prob. But after wiping the data also its still in going through the loop . Please help .:crying:

[Completed] Problems with LG Sunrise

Hey guys, I'm having some serious issues with a stock LG Sunrise (LGL15G). My phone was working perfectly fine last night right before I went to bed, however, when I woke up this morning it started to lock up and wasn't responding so I did what any normal person would do and I went to power off and restart. Now when the phone restarted I got an error message saying "Unfortunately, the process com.android.systemui has stopped." I clicked the OK button however the message kept coming back no matter how many times I clicked it. I them proceeded to pull the battery out (the phone was not allowing me to select my power off option while holding the power button) and replace it and start up the phone. This time I got a black background and the same message and if I press it through about 20-30 times it finally disappears however, I can not do anything with the phone none of the options work except for the power option when i hold the power button. I've tried booting into safe mode and was able to work around the error (with extremely quick timing and proper clicking of the setting button and tried to do a reset however it's blacked out according to server policy. This phone is completely stock with no root/custom recovery, and I can not seem to find a way to boot into a stock recovery for this phone. I know that some of the LG phone did not come with a stock recovery installed but I have no idea how I can fix this issue. I know this isn't a support group but I've been having a close to impossible time trying to find information on the LG Sunrise since it's not a popular phone, I just need guidance to anyone who has any information on this and any possible solutions.

Need Help With my D800 Please

I do not normally post on here, just read and learn =) However, I'm having an issue with my G2 for AT&T. I have a Nexus 6 and cracked the screen, I was trying to get my G2 up and running until my replacement gets in. I had CyanogenMod on it but did not turn on the phone in quite a while. Got an update, did that and nothing was working. Could not even get Google Play services working at all. Flashed a random ROM to see if it would help and now I cannot even get into recovery. The phone operates fine, however if I try to do the power button + volume down button to reset the phone, I get to the point where I hit the power button twice and the phone resets. I've selected rebooting into recover a hundred times with no luck, it will get to recovery and before I can hit anything....reboot. Last night I tried to go back to stock with LG Flash Tool (after downloading everything I need to download) but keep getting Fail after unplugging my phone and plugging it back in download mode. I know long paragraphs are not well liked here but i feel i'm sort of o ut of options other than reaching out to you awesome people! Just wanna go back to stock at this point. I've never had this issue where I cannot even get into recovery but the phone work perfectly fine! grrrrrr

[Completed] Samsung S5 Stuck in an installation loop.

I just downloaded the update for Cyanogen Mod 13 and I clicked install then my phone powers on (no matter what buttons I press; power, power and volume up and home) it has the Samsung S5 logo and the text "Recovery booting..." (as well as the other warranty text stuff). It then quickly flashes the screen with the Android and cog logo with the text "Installing system update" for the shortest time (making it almost impossible to read the text) it then flashes this screen on and off every 5-10s for the rest of the time. I thought that the screen maybe just a little glitchy but the "update has been running for almost an hour now. How can I fix this problem if my phone doesn't allow me to put it into recovery mode .

So I spent about 3 hours trying to fix this problem trying every combination of buttons to press on boot as well as trying to make my phone detectable or something like that. Let my Mum try fiddling with it (she has no idea what she doing with new tech) some how she managed to press the buttons just right. It went into download mode and I was able to flash it with an update of TWRP using ODIN and it rebooted and started up. If you haven't already try putting it into download mode, I've heard getting the timing right can be tricky when your phone is doing unusual things. Now I'm unsure whether to try updating again but I might try wiping and going back to a stable 12.1.
Mod Edit:
Thread closed as ODIN fixed it
