Hi!
I've flashed my phone quite a few times and now I can't get pass the tri color boot up screen. It all started when I started to use task29 for my flashing. Wasn't the first time I used it but the last time I did the phone just ended up with (what it seems like no rom). When I press the power button the phone loads the tri color screen saying serial or USB (if USB connected) I've tried to reflash with both SD-card and USB but it ends up the same way. Flashing reaches 100% (tried stock rom and others) but when booting up it still goes to the tri color screen.
Using SPL 1.56 OliNex.
Hopefully somewould knows what to do. Big thanks!
looks to me like your volume down button may be stuck in, see if it is and what happens after that
Hi. Well the volume button is stuck but it usually works by pressing the power button a couple of sec. now that doesn't work

then you need to unstick the button, it will never boot properly otherwise.
Running nero 5. My daughter touched my phone and when I saw it it was shutting down and then didn't boot up but instead is on a screen with a yellow yield sign with android sweeping and it says "downloading... do not turn off target!!!"
She must have held the power button, but I have no idea what else she did. Can anyone help me? I have no idea what any of this means.
it looks like she was able to accomplish something that many here have a hard time
Your phone is currently in downloading mode. You can exit it by pressing and holding power until it shuts off. Then press power key once again to start it up. If that doesn't work then make sure USB is not connected and open the back cover take out the battery, wait 10 secs, put the battery back in, close the cover and press power key once to start it up. It should work.
Darn kids! Just follow what VICosPhi said and you should be just fine.
I feel like this is a stupid question, but here we go anyway. I'm on an LS980 with TWRP 2.6.3.4.
I can boot into recovery just fine, as long as I use adb reboot recovery, or any of the methods to do a reboot to recovery from software. For the life of me, I can't get the volume down + power key combination to work. This would be no problem, except I'm stuck in a bootloop (my own fault), and can't get to either the software solution or ADB.
Yes, I've followed the directions in which you hold the two buttons, and when the LG logo appears, release and repress them both. I've done this about a million times now, in every different pattern and length of delay I can think of.
If I hold all 3 during boot, I get the "hardware control" screen, with a barcode and my IMEI at the bottom. Download mode, using volume up + plug in USB, works as well. Both volume keys have been functioning fine for controlling volume in software, so they are mechanically sound.
Is there any reason the keys might not work during boot? Is there any other way to reboot to recovery? My only idea is to push the stock image to the phone in download mode, and re-root, etc.
Thanks in advance!
Start with the phone powered all the way down (if you're bootlooping, hold the power button for maybe ~10s until there's a short buzz from the vibrator and the LG logo pops up, then hold it down for a few more seconds to power off).
Hold power+voldown until the LG logo appears. Release them then immediately push them again, and hold for a few seconds.
You'll get a 'Factory hard reset' screen that tells you to press Power to confirm you want to do a factory reset. Push Power a couple of times to confirm this. If you have a custom recovery installed, it won't erase anything, it'll just boot into recovery.
I just tried this, and it worked the first time.
Antinorm -
I'm familiar with that process, and have been trying it nonstop! Here's a video; maybe you could critique my technique?
You don't have to hold both buttons after the release.
1. Hold VolDn + Power until LG Logo appears.
2. Release both buttons for a few seconds
3. Hold only Power Btn
4. You get into Hard Reset
5. Push Power Btn 2 times (For executing reset)
After that the phone will boot into recovery.
Don't do this with plugged in USB cable I don't know why, but it doesn't work if you have a usb connection.
Nope, no luck using just the power button for the second press. Thank you, though! I'll write some more detail of what I see.
Initial state: the boot animation is looping.
I press and hold the power button.
The screen goes blank. I continue to hold the power button.
The LG logo reappears for a moment. If I were to release the power button before this point, the phone would restart.
I do not release the power button; I continue to hold it. The screen goes blank.
I now release the power button. This is the phone in its "off" state. If I plug it in to a power source, a battery charge icon and a percentage is displayed center-screen. Entering download mode from this state works. The phone is not plugged in.
I hold the power and VD buttons together. I've also tried pushing one first, then the other, in either combination.
The LG splash displays.
I release both buttons.
I wait an amount of time. I have tried various values from "as quick as I can move my fingers" to "a solid three-count".
I hold either both buttons (pressing them simultaneously), or just power, and wait.
Time passes.
GOTO 1
Does any of that sound wrong?
Weird. This method works for me. But getting into recovery was a bit of a hassle for me too at the beginning. Your doing seems to be ok... well seems like your only chance is adb right now.

Do you know of any way to ADB without an OS booted or recovery? I don't!
IF your battery is low or almost gone - you can't enter in Recovery with those 2 buttons.
So just charge your battery. I'm using CWM 6.0.4.4 and phone charges battery in this mode. It's slowly, but at the end my battery was 100%.
Now I can go to Recovery with 2 button combo. No download mode for me, but I'll open a new topic for that.

Whelp, sorry. Would have thought you can adb while in download mode. Turns out you can't.
Well i don't have a better idea than you with going stock and start from the beginning.
I'm taking a look at my coworker's Nexus 7 (non-3G model), and it's exhibiting some peculiar symptoms. The most obvious is that the power button was jammed - I popped off the back cover and took care of that. The button has an extremely soft touch now, but it seems to work fine.
It was also booting itself up in safe mode. I figured the jammed power button was causing some weird power cycling, and the filesystem had been corrupted in some way. No sweat, just flash the 4.4.4 factory image.
Still booting in safe mode every time. If I turn it on with power + volume down, I get the usual bootloader menu, and all three hardware buttons work for navigating the menu. Then I continue past the bootloader and get into Android, and it's in safe mode, and the volume down button doesn't seem to respond (though power and volume up work).
Rebooting the device with the ribbon cable for the power/volume buttons disconnected from the motherboard still lands it in safe mode. So I'm pretty sure it's not a stuck hardware button.
For good measure, I flashed TWRP, fully formatted all the partitions, and reflashed again. Same deal. Now I'm running out of ideas. Does the N7 have some kind of auxiliary volume button inputs somewhere that are jammed/shorted, and which the bootloader doesn't look at, but Android does? This is what I see in adb logcat:
Code:
I/WindowManager( 483): SAFE MODE ENABLED (menu=-1 s=-1 dpad=-1 trackball=-1)
I can upload the whole logcat somewhere if anybody is curious/bored enough to look at it. I couldn't find any interesting errors in it, though.
Hi guys! Just got a nexus 7 1st gen and its stuck in a bootloop. It seems that it thinks the power button is constantly pushed in when its not which is causing it to restart constantly. Ive managed to get it to stay on by wedging down the volume up key but i cant use the sleep/wake or volume up and as soon as i let go of the volume up it thinks the power button has been pressed and asks me if i want to power down, but before i can press anything it resets. I have put new buttons in this morning to no avail and cant find anyone with the same problem and was wondering if anyone one here had any idea?
