LG G4(Verizon) stuck in a bootloop, can I recover my data? - Verizon LG G4

Unfortunately my LG G4 is one of the models that got stuck in a bootloop, if you haven't heard, LG has announced this issue and is definately aware of it. My G4 has been rooted for a while, so I am pretty sure that the root isn't the cause of the bootloop. Is there anyway to maybe boot into a recovery mode, or get the phone turned on long enough to recover my pictures, and maybe contacts? The bootloop gets to "optimizing apps" then restarts again.
Thanks.

may be a little late but i've heard some people having success at putting it in the freezer for an hour and then trying to turn it on. will last for up to an hour from what I heard allowing you to get some data from it. there is also a more dangerous method of taking the motherboard out and baking it at a certain temp in the oven for a certain amount of time. you'll have to google it since i don't remember. I'd personally never try to put plastic in an oven though lol.

I had the same issue. Before doing the freezer method try these as i did this my self.
1. Use a fan in a cool room, put the fan on highest setting and make sure you get a good breeze. Make sure the wind is hitting the phone.
2. If you have a ac unit. I dont care what your friends say if its cold out side. Crank that b!tch up. And hold your phone over the air vent.
3. If it is really really cold out side *please note depending on temp your hands will freeze over* stand out side and back your things up to sd card
4. Hold an ice pack over the camera and buttons keep it there till you back your things up
Thats all i can think of and what i discovered. Every time i was in a warm room. Thing keeps cutting off. Please note. Some things required a sd card and when movine files. Please copy files instead of cut. Once finished you can delete your files off the phone
I hope this helps
Edit- before doing anything dont forget to turn the brightness down. This will help keeping the phone to get warm fast

Dash Freezing

Hello all,
I am new to forums and have been searching for sometime trying to find a fix for my phone. Yes, I used the search button before posting. Anyways, I recently got a dash from a co-worker of mine. When she had the phone it worked fine until she dropped it and cracked the screen. I replaced the screen in it and it work fine for a few days. All of a sudden it started freezing on me. I had to remove the battery and wait at least 10-15 mins. before powering the phone back on. Sometimes it wouldnt come back on for a couple hours. I thought it was an issue with the software so I updated to the latest version tmobile offers on their website. This still didnt work. I got a new battery for it (aftermarket) and am still having the same problems. It mainly freezes when ending calls or in the middle of calls. If I "reformat" (dont know technical term for phones) and reinstall software will this fix my problem?
Man, it sounds like you have gotten dust or some type of contamination inside the phone when you replace the screen. These circuit boards are not capable of having dust on these pieces on them. They don't handle well, things overheat quickly. So, I am sure when you make a call, the phone is at its peak power, hence heat.
So, if I were you, open the phone back up, check to see if it looks clean. Maybe, even blow it clean with a can of compressed air. Other than that. It never hurts to flash your phone with a new ROM, but fix a "dead" phone, I don't think so.
Good Luck.
I always start simple.
1. Are you using a memory card? Some cards just dont work well and the access time can slow a phone down alot and even cause freezing.
2. Sim cards can get dirty as well.. clean the contacts off and see if it helps
3. Since your co-worker dropped it, I would look for loose connections.
If all else fails flash a new rom and cross your fingers
Thanks guys. I will try and take it apart again to make sure theres not dust in the phone. There is no memory card so I can scratch that off the list. I will check the SIM card to mak sure its clean. Are these phones tempermental when it comes to clean SIM cards? I ask because my SIM card works fine in my other phone. Anyways, I did a hard reset yesterday and work for about 15mins and then restarted on its own several times. After it did this it finally shut off completley and now I cant even power the phone on or charge it. Looks like I have to suck it up and just buy one.

Either my phone is possessed, or retarted. It wont stay off.

My phone is fully rooted with no nand unlock. And has been working great.... until recently.
I've had my phone on for about 2 weeks straight, because a friend told me its better to just leave it on. Well, yesterday while in the music app, it just went right into the startup animation. No bootscreen, just the animation. Now I noticed my phone was somewhat sluggish and decided I'm just shutting it off for a bit. Well, that's not going to well. It will not shut off. YES I HELD THE POWER BUTTON THEN POWER OFF. even with a battery pull it turns on right when the battery is in. I also noticed that ky ringtones and some settings don't restore after reboot and that sometimes I need to hit the keep button multiple times to wake it. Is this a software issue or hardware..... and if I need to return it, how do I remove the root? Or will they even notice? Could this be related to the root?
Thanks for feedback. Kinda panicking here
I had the exact same issue. What I figure happened was that in the process of rooting (plugging USB cable in/out so many times) a pin probably stuck itself high or low in the connector and caused the behavior you're experiencing now... that's just my theory though, but whatever it is, it's hardware related... so don't bother flashing the RUU and losing root over it -- I did and I kicked myself for it. What I ended up doing was exchanging my phone for another one and after two tries finally got one with a screen that wasn't pink -- in fact it was even slightly better than the original one I had.
If it's a dealbreaker for you not being able to turn off your phone, then by all means replace it. Just keep in mind you might have to swap out more than once if you're picky about refurb quality. Just my 2cents.
As for how to get rid of root, look over one of the RUU threads and download one... when you run the *.exe it extracts a bunch of files to your temp directory. Look for and rename rom.zip to PB31IMG.zip, copy it to your SD card root, and boot in fastboot and let it update from it... result = stock incredible again. Got that trick from:
http://forum.xda-developers.com/showpost.php?p=6679579&postcount=45
Edit: I only had the reboot after shutdown issue. Anything else sounds like something that could be fixed with a data wipe (that won't get rid of root). What I'd do now that there's a custom recovery, is make a nandroid backup just in case, that way if the data wipe doesn't work for fixing the setting sticking issue, at least you don't have to reinstall everything back and can just restore the backup.
Sorry guys...

See, this is exactly why when I was trying to root, I was pulling the cable at the PC end, not the phone end. MicroUSB is a lot flimsier then regular USB. Be careful guys... Oh, and I WOULD reflash just in case. They might give it to a tech to troubleshoot if this is software related, and I guarantee that he'll notice SuperUser.... .02$ deposited.

Right on all counts, I have a usb extension cable the plug/unlug the DI with now. MicroUSB was loose out of the box--me no likee.
As far as sending the phone back with unusual software--I doubt HTC is gonna narc on you given the huge demand for DIs. It's always better to play it safe, but I haven't ever heard of a user getting a warranty claim bounced for rooted software installed, and I've been in the android game for a while now.
Try This

I'm not saying this will work at all, but....
If you're experiencing these things with USB plugged in... Unplug USB, and take out Battery.... Let it sit there for 30 seconds....
( I THINK that the "pins" are only for video out. If I'm correct, the "usb" part of it is actually a plate on the phone, and the pins are in the cable)
Once you put the battery back in, try using the phone w/o usb plugged in... if it behaves normally, replace USB cable. (Unless I missed something in your orig. post.)
Thanks.
Also, before you return the phone, do a hard reset and see if it fixes it (there is a slight chance it's software related.... obviously, you will lose everything, but whatever is backup up to goog. When you rooted, did you delete/remove any APPS at all?)
Ugh.... I do not want to return it. I hate refurbs. If i return it, is there a chance ill just get a new phone? Aside from that, i think i can confirm its hardware, more specifically in the usb port. I plugged in the charger and now it turns off fine. Annoying as hell, but i think im just keeping it. And after looking more i see that the screen never actually turns off, it just pauses then turn back on. I havent noticed and horrible side effects and maybe a reflash would help me. I never shut it off so ill deal for now.
Now if i want to do a nandroid backup, do i need to be in hacked recovery or will it work immediately? and can it be copied to an sd card and restored to a refurb if i got one?

HTC Desire fell in water, now won't boot.

Hi, my apologies if my HTC is in the wrong forum, not sure where the Desire would fit, if anywhere.
Nonetheless this is a useful phone to me and worked fine till the day I had to jump in a lake to save my 5 year old boy from drowning. Naturally didn't have the time to remove the phone from my pocket before jumping in the lake. Kid was fine after swallowing some water but phone "swallowed" a lot of water. Let it dry in a bag of rice and baking soda for several days to fully dry. But when trying to turn it on, the screen just flickers non stop. However when connecting it to the computer using a USB cable, I get what appears to be a boot screen (see pic in address below). Phone was rooted and run CyanogenMod 7. Maybe someone that's familiar with the procedure could guide me? Tried a couple of the options shown but to no avail. Old but still decent phone, would like to get it working again. I've transferred the sim to another phone and I've saved the micro SD card. Just need to get the phone to boot again. PS: could the battery be toast? Maybe it got shorted when I first tried to turn the phone on while still wet?
Any help is appreciated.
I'm too new here, won't allow me to post external links. Please go to h-t-t-p://tinyurl.com/p4dmgej (remove dash from http)
I'd say leave it to dry naturally for a week or so and try again. If no joy then you could try a new screen but it's probably something really tiny and sensitive that cannot be replaced..
Glad you saved your boy!.

It's been 2 months. But I did make a crucial mistake: I tried to turn the phone on while still at the lake. This likely caused more damage than it needed.
However I suspect the issue is with the battery. It won't charge past 3.85 volts. And the display works just fine, once I press the key combo to enter the boot screen as seen in the pic above. Will try and track one down locally, hopefully a shop will be able to test it a battery in the phone before I buy it.
And yes, the boy was fine. But it was a close call. it is amazing how quickly something can go wrong. I neglected the lake rule of staying within arm's reach. Let this be a lesson to anyone with small ones: it only takes seconds for things to go badly wrong, even at a supposedly safe, man made lake intended for kids.
PS: 2 months prior an adult died on the same lake after falling off his boat. Another lesson: invest in swimming lessons. Scary stuff, indeed.
Right, i thought you were seeing that over usb via sdk or something.. You could always try opening it and inspecting for blown components. What damage can be done.. It's already useless.
I still think it's worth leaving it to dry naturally.

Phone charges... but wont open?

Guys, I need help.
My One M8 finally gave in-or so i thought. After the volume rocker failing and falling off, and both cameras failing I started looking for a new phone.
Then the power button died.
So now, the phone semi-functions, at least it is usable for a backup for the time being. But, since i dont have any buttons, i cant get the phone to open.
Does the phone automatically boot itself when charge reaches 100%? If not, is there a way i can get this phone to open, I will get it repaired but i doubt it'll be done without the repairs formattiong the phone, which wont make sense...
Thanks!

No, why would it do that? Some folks like to charge it overnight, with the phone powered off; and not want it coming on for no reason in the middle of the night.
I don't think there is a way to power on, without the power button.
nice!
i just realized my sd cart got bent too-i think i have to say goodbye to all the stuff on that phone :I
the S7 seems like a nice phone

That poor phone...
What did you do to it!?
I dont treat my phones well after a certain point, with that point being a single scratch or dent or something.
I was doing an experiment, and i spilled motor oil (castrol edge 5W-40 if anyones interested) and it stained my case, and from that day on I didnt use the phone with a case. i forgot the phone on the table during a flash summer rain-front camera destroyed, rear camera i have no clue how it went out lol
it was like new for a year and a half though... ;P

You should be regularly backing up your data then (many good solutions around). Really, everyone should. Wondering how to get data after the phone after its broken, is too late.
I never store anything important on internal storage. One day it will be inaccessible.
I feel sorry for your abused phone.
eh, its nothing too "important" just pictures that i received on whatsapp. rest were on my dropbox.
i got a silver S7, so i guess this thread can be closed.
I also looked into what I could do, turns out the power button is built in to the daughterboard. thankfully, i found and ordered one for $38, hope it'll at least work enough for me to get the data off it!

Temporary boot-loop solution to back up your files!

Disclaimer: I am just stating what worked for me, so if anyone's warranty is dismissed, or phone further breaks, it is not my fault.
Hey guys, so my phone started bootlooping about a month ago, but I have my warranty still so I am eligible for a G4 repair, (as well they agreed to fix my G2 from two years ago). Anyways, the problem is I didn't have some contacts, pictures, etc.. backed up so I needed my phone to function for about 20 minutes to back them up. I tried the freezing method, every button combination possible, even held the power button down for 10 minutes. Nothing worked. Until I found this reddit comment from a while ago.
https://www.reddit.com/r/lgg4/comments/3vsebk/retrieve_data_from_dead_g4/
The comment by.. uh... "Irapedyourcat" about heating the phone helped me. Now I used a hair dryer instead, and basically followed this video tutorial. It isn't the greatest, and one of the videos is 40 minutes long, but I skipped through most of it and you really don't NEED to watch it. He just mentioned some bumps you can experience and decently described the steps.
https://www.youtube.com/watch?v=TkMhaLryn-A
https://www.youtube.com/watch?v=uN6baDuozms
So I'll just go over the steps of what to do and what materials you need.
Materials:
- Hair Dryer
- The phone -_-
Steps:
- Take the battery out of the phone and be ready to put it in. (Keep nearby and away from the hot air of the hair dryer)
- Plug in the hair dryer and expose the back of the phone with the back cover off.
- Watch the time for about 3-5 minutes. Don't go over I would say 6 minutes.
- Slowly start from the bottom left corner of the phone, and move up to the top part of the battery hole. (Don't go over the buttons).
- Then from there move a little to the right, then move back down slowly. You want to leave about a pinky's length from the phone to the hair dryer.
- Just keep zigzagging until you reach the bottom right. Then go up to the top right corner, to the right of the camera, and heat that area for a little bit, definitely a shorter time than the bottom area. Then skip the camera and then move to the top left area.
- After you do that about twice, or for about 4 minutes, feel the phone. It should be really hot. Like enough to go "Ow!" Not jerk your hand away or it'll burn you hot but maybe a window of a car left in the sun in an empty parking lot for a while.
- Once you feel the temperature is right, (I'm not sure if this helped or not, but I did this process twice and the time where I did this the phone turned on for a longer period of time), focus your hair dryer solely on the 4 little gold things that your battery connects to. https://ibb.co/cKSnQa
- After you do this, turn the dryer off, and put the battery back in
- Start your phone, and once the logo shows up, plug your phone into the computer. (Or if you don't use PC, you can just use the phone and put it into a SD card, or use a cloud service. Personally I think the phone can stay on longer if you just control everything from computer but whatever works. If you DO choose to use a computer, make sure to click "allow" when it asks for access.)
- Back up away! If the back up is taking a long time and the phone starts to cool down, what the guy in the video did, and me too, I heated it with the dryer for about 5 seconds at a time, just on the bottom half of the screen and some of the sides.
One thing to mention is that the phone does get really hot. That's the point, it has something to do with "melting" the cicuit board and some connectors together or something??? I'm not really sure so if someone clarifies that, that'd be pretty cool. Anyway you will get warnings that 1) your phone is at a very high temperature and then 2) that if the phone gets any hotter the phone will shut off. (That's what happened when I heated it too much while it was backing up because the phone was starting to cool down so just do it for 5 seconds every minute or so!) https://ibb.co/nrfwJv
I'll mention again that this could work or could not work. This is pretty risky, I'm not gonna lie, but if done properly, you'll probably have a good chance of succeeding. The reason I'm posting this is because I kept thinking "what if I saw this right after my phone started bootlooping?", and it would have made my life so much easier if I found this way.(I've been without a phone for 3 weeks, just needing to send it in for repairs, but feeling that I could somehow manage to back up my files, but I didn't have a way). So I decided to not be lazy and write this. It's less risky than "baking" it, so if you're considering that, then try this first. Hopefully no one made a post exactly like mine because that would suck because I'm super tired right now but I hope this at least helped one person. Thanks and good luck!
