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

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!
I honestly need help.
I'm not sure what to categorize my issue under.
I am stuck in a screen with the green android and the spinning thing in the middle, with a progress bar, but the bar just has a moving animation, looks like it is moving to the left, not getting longer or filling up like usual progress bars.
I am unable to get to the boot loader or recovery.
The issue started after I flashed Cyanogen Mod 10.2 Stable.
it booted fine then, but when I went to use it, it would have a never ending cycle of app not responding at the part where it asks to sign in to cyanogenmod account. I got to settings without signing in by quickly sliding the status bar and clicked on factory reset.
From there it proceded to reboot and now I am stuck in the screen described.
I have tried all the button combinations, reset with pin, nothing will get to bootloader or recovery.
ADB does not find the device, also no devices found when try fastboot devices line.
I have also tried putting the firmware zip on a microsd, but nothing new happens either.
any suggestions appreciated.
** edited ** Issue is resolved. Turns out I just needed to wait longer (about 2 hrs) ... I did turn it off using combo of power and Vol -, left it off overnight, turned it on in the morning and left it alone. I finished whatever it was trying to do, and now CyanogenMod 10.2 stable is working great.
So, yesterday I decided to reboot my phone since it was very sluggish for whatever reason. I think it shut down properly but when it came back on, there was a very interesting problem that had come up - it didn't boot any further than the logo screen, which didn't even play its standard animation; it just stood there with the LED on the home button changing colors (like normal). I left it on overnight hoping the problem would be gone, but to no avail. It still hadn't booted when I woke up. If it matters, the only thing I can boot to is download mode. It doesn't let me get to safe mode or however it's called (the menu you navigate with volume up/down and the power button). Needless to say, I was very puzzled. Then I went on and tried to flash the latest kdz since I thought that would fix the problem. I hoped that would easily fix the problem. But no, it decided to be funny and give me more headache. I tried using this guide: http://forum.xda-developers.com/showthread.php?t=2409308 but after step 20 the LG Mobile Support Tool crashes and I can't continue. Sure thing, I will try the Upgrade Recovery that the tool has built in. It properly detects my phone, the software download and extraction goes smoothly. Then I reach the S/W Upgrade part of the process. The few first seconds everything is fine, but then the bar reaches 5% and just stops. Just like that. Now it's been 8 hours since I began the recovery and no progress has been made.
Can anybody help me? I'm lost here...

First off, my google pixel is 100% stock. Last night when I went to bed, I had no issues with my phone. I woke up in the middle of the night because the screen was on and very bright. It was the white google boot screen, but with a bunch of corrupted text sporadically over it, and it was stuck there. I held down the power button to reboot, but when it did it would get to my unlock screen, but be frozen there. After about 5 seconds on that screen, it would reboot itself, and just continue that over and over. I tried holding down the volume down button to get into the bootloader, but when I go into recover mode, it just gives me the logo of the green android guy with a red triangle exclamation point on it and it says "no command" below it. So I reboot, and the only way to stop the boot cycle is to to back into the boot loader and select shutdown, so that way it will stay off.
Any words of wisdom? I was really not looking to get a new phone at this point...
I'll add that I used the instructions here to try to apply a rescue OTA using ADB according to these instructions: https://drive.google.com/file/d/0Bz6x7k-VkpUJMlZ1aEliVnhMOHM/view. It completed successfully, but didn't make any improvement on the situation.
Update #2: I ended up trying to do a factory reset from recovery mode and that also doesn't seem to have helped.
Did you try installing a more recent OTA than what you originally had?
I already had the most recent OTA so I can't get a more recent one.
Try again in a few days when the February update is released. If it still doesn't work, it's possible a memory chip got fried.
If you're in the US, look up your nearest uBreakiFix location. They handle all Pixel warranties in the US. There are a number of reports in various threads of people getting their phone repaired for free, even outside of warranty.
I am in the US, but the nearest location for me is about 1.5 hours away. I guess I could give them a call to find out if it's worth the drive.
Why do you think a new OTA update would help where an old one wouldn't?
Is there any way I can flash the full image without having previously unlocked the bootloader?
Well i am experiencing the same problem on temporary basis since 2-3 days and the problem seems to be with the power button. I get it fix when i take it out of the body cover and try to clear the dust around power button and seems to fix it but it still happens in the morning or at night at home.
I did search my terms and didn't come up with anything close to my situation, which is this: I got this phone in 2013, rooted it successfully, but was never able to get TWRP flashed properly, but I was happy with the root, so I sort of ignored the TWRP thing. Now I am getting a replacement phone, LG-V20 VS995 next week, so I decided yesterday to tinker around again with TWRP, as I wanted to put this on the V20.
On the G3 when I flashed(Or so I thought) TWRP and rebooted to recovery, I would get an error message (Very small) in the top left of the screen, then would disappear and I would have to pull the battery to reset and then it would boot fine back to the OS, but not to TWRP.
I made sure I had/have the updated Windows LG drivers, ADB, etc.... and I could see my G3 in Windows properly, the internal device and the microSD, I even pulled up the terminal emulator on the G3 while attached to the PC and ran an ID command I think, successfully. I pulled up a CLI in Windows in my ADB directory and my G3 device showed up as well. Then I tried flashing TWRP, first using Flashify; I started with an older version, like 2.8.6, but it didn't seem to work, so I started going towards the newer versions, but still, Flashify kept saying they failed to flash. So I tried the official TWRP app, and it seemed to be doing the same thing. So I went back to review what I had already done, then disconnected my phone from the PC, rebooted normally and tried again with the TWRP app. I think I was successful with one of the newer versions, 3.1.x so I did the reboot after it said it was successful, but I got that boot error message again, then blank screen and red/blue flashing lights; removed battery and replaced, powered on for normal boot and back in the phone OS again. I checked some YT videos on flashing TWRP on VS985 and it appeared I was doing everything correctly, but then I saw this one video that stated to use the Vol+ and Pwr button (I guess I thought when I selected "boot to recovery" the phone was going to do that automatically), then once you see the LG logo, release the Pwr button, then continue to press the Pwr button all while still holding the Vol+ button down, and then you would go into Recovery mode.
His next words sort of came as a shock - you had to select the option to reset your phone to factory defaults, and THEN, and IF you were successful flashing TWRP, it would take you to TWRP. I thought about this and and decided to do another TWRP flash, and if successful, would try this method. I did and I was able to get into the stock recovery menu, and I did see the option to "Reset phone to factory defaults", but decided just to cancel and went back to the phone OS, and that worked. Later on, I decided to try the "Reset" option on another phone boot, but I've now run into a different issue/error. When I boot the phone, I immediately get the error message (The boot certification verify error), and no matter how many times I remove the battery or for how long, each time the phone boots, I get this error message. The only thing I have been able to do is get into the Hardware Key Control Mode using Vol+Vol-Pwr and just continuing to press them. No matter what option I choose, either Cancel, Mode On, or Mode Off, the phone immediately reboots to the error message; it's like it's stuck in the Recovery boot mode somehow. I'm not sweating it too badly, as I've got a V20 coming next week and I have a work cell I can use for important things, but has anyone run into this type of thing? The way it is now, I cannot view the phone on my PC and cannot seem to get past this boot certification verify error.
EDIT: I am now able to consistently boot into the System Recovery by way of Vol+Pwr button held down until the SR menu shows. HOWEVER, no matter what choice I select, phone reboots and I get the "Boot certification verify" error................ oh well, at least I got an email that my V20 is coming this Thursday.
EDIT: I must be somewhat dyslexic, as the method to get to the SR menu is VOL- (Not Vol+) and Pwr button held down until SR menu entry. Sorry about that
EDIT: I've also seen the "fix" where you remove the back cover, battery, and then remove the top plastic cover over the battery/power/volume, then also remove the metal shield. This is the point where it gets confusing; the author(s) want you to "ground" 2 of the contacts, but it's not clear which ones they are referring to, even with the screenshot, and I'm not electrical engineer, so not exactly sure what they mean by grounding. As I'm getting a replacement tomorrow, I decided not to even explore this technique, although I did dissassemble the phone down to removing the metal plate, so I could try and see if I could figure out what they were talking about (I couldn't). Gotta say, I've had my G3 for over 7 years and for the most part, really loved it; it came in handy during home power outages when the Internet (Cable) went out.
