[Q] HELP!! Stuck in LG boot logo!!!

Please help! My rooted LG Revolution won't turn on. When I unplugged it from the charger this morning I powered it off. when I went to power it back up all it does is flash the LG logo and do a little vibrate like it is force closing! I have 2 days left before I can no longer return it. I did several battery pulls also with no luck. thanks in advance!

Did you install Clockwork on it, or just rooted?
If you only rooted it, try performing a factory reset.
This can be accomplished by holding volume down and power until you see the screen change to "Clear data and factory reset?".
Press power to confirm.
You will lose your data, but your phone should return to normal.

Just rooted, no clockwork. I will give it a try! thanks!

Tried your suggestion...just keeps flashing and vibrating. Any other suggestions?

Did you ever see the factory reset screen?

No I didn't. just the LG logo flashing and the force close vibrate. the only way I can get it to stop is to take the battery out and put it back in. Then when I hold the voume down and the power button it just starts doing it all over again.

make sure you are holding it long enough. You have to continue to hold the power and vol button for sometime before you get the recovery screen.
As rooting will generally not brick a phone (it is the recovery mod that generally bricks), if you cannot get it, take it back tell them you woke up and it was on the charger like this. They should exchange it with out issue. (Do not mention that you rooted the phone)
It sounds to me like your phone is defective, it happens.

Another option is here: http://forum.xda-developers.com/showthread.php?t=1120062 .
I can walk you through it on IRC tonight if you're on around 12PM Pacific Time...
If not, there are guides for using LGNPST on the internet.
Good luck!

Thanks! Held the buttons down for a full 3 minutes and nothing. Is that long enough? Read through the other info you posted and boy does that look scary! LOL! I will try tomorrow when I have more time. Or maybe I should just return it since I have only had it for 12 days

try pulling the battery and holding the power key for about 30 seconds. my original droid use to do this from time to time and it always worked for me.

Thanks. Tried but it did not work. Ended up just returning it and getting a new one. Now I can start over! LOL Just came from the Samsung Fascinate and was pretty proficient in flashing roms and kernels. But I have to admit that I am a little confused with the process on the Revolution.

Not sure boot problem is related to root
I've had repeated problems with not being able to boot my Revolution. This has happened consistently no matter which ROM I've used. I've factory reset and tried Decrap and Revolt both. I can reboot my phone fine, but if I ever turn it off overnight, I go back to a blank screen in the morning.
It seems a number of non-root users have this problem.

I'm not sure if having a low battery contributes to the problem, but I do know that Clockwork works better with a full battery.
This morning is the first time, however, that I have this exact problem. For a few times this morning I was able to get to clockwork and restore different ROMs, but always to the same blank loop during boot. Now not even able to get to Clockwork or Factory Reset. I'm headed in to Verizon to try for a replacement. I'll let you know if they make any noises about rooting.

Getting back into Clockwork
Update: I ended up getting back to Clockwork. Can't say exactly what did it, but what seemed to work was:
1. Charging the battery fully overnight
2. Removing the battery and holding the power button down for 30 seconds
3. Leaving the battery out for some time, about an hour I guess
4. With the battery still removed, plugging the phone in and allowing the bottom lights to flash about 10 times
5. Replacing the battery, holding down the power button and volume down.
After a full day of not being able to get into Clockwork, I was able to get in and do a factory reset.

Returning Rooted Phone to Verizon
FYI, I returned a rooted, stuck in boot loop phone to Verizon yesterday. In the store they arranged the return and did not ask about or look for rooting in any way.
They did try a factory reset, which was not working in any case, so no signs of Clockwork.

Same problem, different results.
I have a ROOTED LG Revo, but the first one I owned had the same problem. That one was NOT rooted, so must just be an LG thing. First phone had stock android 2.2, and this one has STOCK 2.3.4 ( after OTA ), and is just rooted with simple memory management and font tools. I WAS able to Hard Factory Reset, but the same problem still existed after reset. ADB cannot even recognize the handset. Boots with animation, stops halfway through, reboots into blank screen and freezes. RETARDED!!! This will be the second handset being sent back in as little as a month. I bought the REVO the DAY it came out, and loved it. But now I don't. No love left. I'm getting the Droid Razr!

HELP HELP

plz help....was using Zeus v6.39n overclocked to 1100Ghz and underclocked to 200Mhz..downloaded some Lg stuff from Heuxx's blog(car home & smartshare)...rebooted my phone to flash it and it won't boot after that....tried everything, no use...then finally use smartflash and flashed to v20B....phone booted and I was installing my apps...after some time the display went off as it got locked while I was not using and now its not coming on....Iam getting calls and messages and the LED lights are blinking but the screen is blank...tried reflashing....now its not booting at all....NO LG logo also...although I can see the LED blinking...plz help

try flashing with smartflashtool again
i think it might be your lcd itself or the cable

i have alredy flashed 2-3 times....also after I remove the battery and put it back and switch it on, I can hear the sound of LG animation like when it comes in stock and the led lights are blinking normally as it happens during powering up...But the screen remains dark...

sumthing happened to ur screen then... if u still have ur warranty then bring it to them.
if it's because of the screen then they will replace it for ya

thanx....I went to the customer care...they also tried flashing(I guess)...then they told me that its not due to software but hardware problem and that they will replace and give next week

[Q] after the first update my phone wont start

After my first update the phone is dead, I have my htc inc s for one
week(I think it was android 2.3.3 and it worked fine yesterday I got
update notification I've downloaded it and then the phone shutted down
and started with the dark screen with the green arrows in circle and
one inside facing down symbol and it stayed like that forever!I took
battery out and put back press power and its the same symbol! The phone
is from china got it from ebay and if I need to send it back for fixing
it will take a lot of time to come back!
So I tried battery out back in, volume down + pover the same green
arrow symbol,like this when plugged in my pc doesnt do nothing,after I
tried battery out than in, volume up + power and I got 3 vibes, orange
light and black screen, when plugged to my pc i says "qualcom CDMA
technologies MSM" device and it searches for drivers!
I dont believe that its possible to brick my device with the first
update that I got from the mobile network and I never touched nothing
like rooting or messing with my phone...
So what can I do now to fix it without losing my waranty and having
everything like it was before stock and working???
PLEASE HELP PLEASE HELP!!!

Freezes, reboot and other funky things

Sorry for my bad English
Hello friends of the forum, I present my problem. I was given to repair a S3 LTE really is driving me crazy. We'll explain: the owner did filth with ROM to the point to make it unusable. Turns on, but after a while it stops and turns itself off. I tried to flash the stock, wipe system etc .. from recovery and put back the stock, but every time I turn on the phone and get to the Initial Setup (the one that says Samsung GALAXY which allows choosing the language) crashes and off. Also known that the recovery is very very slow (both TWRP that stock that cwm). I managed to flash rom 2 including Cyanogenmod but this crashes. Sometimes the poor cell can not even start that hangs on and off. I tried to replace the battery with one that I already had and the situation does not change. I wanted to try to do an update of the bootloader because I think the problem is the. Further inform you that when it crashes but is charging if I remove the battery on the phone stays on but completely locked and I can not even press the power button for 3 seconds, because it is completely freezed. Another observation I have noticed is that if I leave him in charge when switched off the led solid red, the screen shows no signs of life and if the detachment micro usb LED remains lit sign that is completely blocked even when it is charging (WHILE TURNED OFF!). I hope you can help. I tried everything

Maybe it's power button problem.Check the power On/Off .

H811 won't boot after multiple battery pulls... HELP!

So I can't boot my phone. Previously stable h811, unlocked bootloader running latest 20i Extreme 3.3 MM with G4 Tweaksbox. I have a Qi/NFC sticker on the back, but which has worked flawlessly and was not in use when the phone died. Here's what happened and what I have attempted.
Problem began when phone simply went black. The only thing running was Maps, which had a route displayed but was not in navigation mode. The screen went dark like normal, and when I went to wake the phone, nothing happened. I was in the car and tried plugging in the car charger and did not get a charge light. Pulled the battery and was unable to get a response. The phone and battery were quite warm.
When I got home, I tried a different battery, and the screen turned on to the LG initial boot screen, but nothing else happened.
After many battery pulls and attempts to boot into recovery, I tried it with the phone plugged into the computer. Finally, it showed the charging screen and light, and after several more attempts- pulling the battery and inserting it, then powering on, it appeared to be booting, (boot animation started, but then looped and froze on the initial boot screen (with bootloader state: bootloader unlocked in the upper corner). After another round of attempt/battery pull, it booted all the way up, but at that point I had my sim pulled. Pulled the battery and tried to restart and it froze on the initial boot screen again. Haven't been able to get into recovery at all, can't get into download, can't boot past the initial LG screen. Sometimes it loops, sometimes it just hangs. Nothing I do pressing combos of buttons, plugged into computer or unplugged, seems to change anything. The very farthest I've gotten is the breathe blue light before the boot animation, but then it looped. Now it's boot looping plugged into the computer.
Any ideas? I'm at a total loss.

Im bricked myself from another issue but i think there is a black screen of death issue with some of the g4s
Try to boot download mode and re flash stock kdz with Lg up tool
You will loose all data though.
Good luck on help here noones helped me at all .
The g4 is just not a good device or user friendly
Sent from my LGMS631 using XDA Free mobile app

Black screen of death here too
Yesterday, I was using Chrome, site loading, screen just went black. I had about 1/2 battery at the time. I figured maybe the battery was just reporting wrong. When I got home, swapped batteries, same issue. I've been able to get into recovery and attempt a factory reset a couple of times (after many frustrating attempts.) The phone seems to only be able to be powered on for about 30 seconds before it goes black again. I'm going to attempt to fix with download mode now. If anyone else has solved a similar issue, any tips would be appreciated.

Hardware appears to be at fault!
Check this out, people!
http://www.androidauthority.com/lg-admits-g4-bootloop-problem-hardware-fault-669603/
Spread the word. Sounds like this is our problem. Apparently affecting mostly models with serial numbers starting 505xxxxx... which is what mine is. Called LG and they issued an RA# and shipping label to send it to them for service. I'm a little concerned since I didn't buy mine through a carrier, but this seems more like something of a soft recall than strictly a warranty issue, so I'm hoping they fix it no questions asked. I'll keep you guys posted on the progress.

Same thing happened to me today. My phone randomly shut off and it won't boot. Its stuck at the Android logo. I wasn't messing around with it. Just normal use (Snapchat, youtube). I tried booting into recovery but it just goes back to the android screen LG logo and keeps looping. I at least want to wipe the phone before I send it (personal info).

Same here. Mine has serial number starting 505, was purchased back at end of 5/2015 with not problems until this. I filled out the warranty repair form on LGs website and they sent me an RMA with label to get it fixed. I sent it in, they sent it back, and the only thing I see is on one sheet they printed out and included in the package said 'replaced board'. However, when I started up the phone it looked like new initialization with xx of yy apps initializing and then it began bootlooping with the LG splash screen. So frustrating!
So, this time I contacted t-mobile via their online chat, and did a warranty exchange through them. They will send me a replacement LG G4 next day ups air and I will send them the defective one for them to claim warranty themselves. We'll see where this goes. I might just take the replacement unit and do a tmobile jump exchange to another device. I wanted to wait for the new line of HTC nexus phones that are rumored for this year (and was loving the LG 4 until it died), but I might need to just jump twice this year and go for something like the new Samsung S7 of new LG G5 now and then again switch to HTC nexus once that comes out.

Sent mine to LG, and they fixed under warranty with no questions asked. Got it back within a week. All good now.
