And my replacement phone broke again.. The freezer method worked again. But the replacement (my 2nd boot looping phone) usually won't even Boot Loop. When I plug it into a charger nothing happens. Insert a full battery and try to turn it on, nothing happens. I had to press on the back really hard to get any power to the phone. Then I was able to use the freezer method for a few days, my replacement has came and I cant get it to work again. I just wanted to double check that everything was backed up, I may be out of luck...
[T-Mobile LG G4] r3dd09:
NVM, just realized this is the G4 forum, not the v10. Best of luck with bootloop issues.
[T-Mobile LG G4] lm.1:
HELLO.

THANK YOU EVERYBODY FOR YOUR INPUT.

I am getting a replacement in 3 days but I still want to get all of my data. It's great that it worked for all of you.

Though, I have not tried it because I'm afraid that it will trigger the LDI (Liquid Damage Indicator, apparently there is a white paper indicator that turns pink/red when in contact with water or moisture. It can be located either above the SIM/SD card slot (circle-shaped), near the battery contact (square-shaped) and/or on the battery itself (circle-shaped) - near the contact, also).

Did your device got wet or moist after you did this method? Any of your indicators turned pink or red?

Is there an extra precautious way to NOT get it moist or wet?

A reply is VERY MUCH APPRECIATED.

Thank you in advance,

Liv

Hello all,

I am looking for a new smartphone, especially one with a great camera in pricerange till 450 euro. So the LG G4 came in view. However, the boot problem scared me a bit. Have the phones been recalled and repaired, so i buy an errorfree unit?

Can somebody please tell me this?
[T-Mobile LG G4] celsius0010:
Unfortunately the freezer method does produce ALOT of condensation. On the good side, it has NEVER triggered an indicator, not even a partial trigger. But I would imagine it is possible. Double check your battery indicators especially because you obviously can leave the battery at home if it were to be triggered.
[T-Mobile LG G4] raptorddd:
supposely the 601 are free of bootloop but it isnt the case we seen some get bootloop..
[T-Mobile LG G4] maw230:
Trying this tonight. Wish me luck.
[T-Mobile LG G4] raptorddd:
why nobodys done a modded KDZ?? or TOT??? like the one for the H815

instead of using the freezer.? is it cause theres few bootloops on h811?
[T-Mobile LG G4] celsius0010:
I believe those modded flash files have to come from LG. I haven't read up on it much but from what I gather they turn several of the phones cores off to reduce heating below the failure threshold. This hurts performance very bad, so the phone is not usable; you are just able to retrieve data.
[T-Mobile LG G4] raptorddd:
i think they the users modded the file. yes but i think its better to retrieve data this way. i also tought about the liquid damage. using it on fridge..
[T-Mobile LG G4] Hawker17:
Thanks Raptor. Yesterday i was in a T-mobile shop. Many units have returned with the bootloop problem. Most customers had to pay for their repair. That's the part i don't like. It's a manufacturing defect and LG should take responsibilty for it. The salesman agreed with me. I even emailed LG about this issue and asked if they are recalling all units. Unfortunately i got this answer:

Dear -------,

Thank you for contacting us regarding the issues with LG G4 models.

There have been some issues with this model where the telephone does not go further than the start-up screen. When an issue arises our service center will look at it on an individual basis in terms of providing a solution for the problem. At this stage this model has not been recalled.

I hope we have informed you adequately.

Kindest regards,

--------

Customer Service Representative

LG Electronics Benelux Sales B.V.

I am definitely not going to buy the LG4 or 5. I don't like their attitude towards this problem.
[T-Mobile LG G4] aryan.yazdani:
Hey, I've now bootlooped for the first time as well. I have something like 20GB of images to recover and that's about it. Can you further explain what these modded files are, or what to google so that I can get past the bootloop (even for 1-2 hours)?

Thanks!

Someone said to edit just H815 with H811. with hex program.. someone tried it and got it bricked..
[T-Mobile LG G4] lm.1:
IT WORKS!!!

THANKS TO SIR celsius0010, bel57, revo420 and LoyPerera. I have tried the freezer method and it worked for me.

I left my phone, with the battery attached, without the back cover, SIM and SD card - inside a Ziploc bag with a silica gel pack (trying to be cautious with the LDI), inside the normal sized freezer for 1 hour. It turned on for 45 minutes for me to back up and luckily I got everything I needed. I tried a factory reset to delete the data but it doesn't go through. Then, it went back to the bootloop again. I couldn't believe it worked for me. I am still waiting for the replacement for the phone and hopes that this new one doesn't have problems. But if it does, I have a method to open it temporarily. Now, I know that BACKING UP is important.

So for LG G4 USERS, BACK UP YOUR PHONE NOW.

Again thank you for all of the people who posted on this thread. Especially, the original poster celsius0010

Cheers,

Liv

Dude! This would have saved me so much time. I literally spent a day trying to fix it before I discovered this. Now to find out that if I'd done more homework, I may have saved some time. Lol oh well. I discovered the same thing like 2 days ago.
[T-Mobile LG G4] ub3rx:
This really helped me back up my stuff. Now hoping my agent would still let me claim warranty even though I'm 4 days over the warranty period
[T-Mobile LG G4] SuhasTheBest:
HOLY CRAP THIS IS INSANE! My LG V10 has been boot looping for a couple hours now and i was freaking out because i had a ton of files on it. I threw my V10 in the freezer and 10 minutes later it booted up and now says android is upgrading! I can just copy my files to my sd card now! Thank god. I never thought this would work. I wonder why this works
[T-Mobile LG G4] mtseasky:
Would the battery be damaged in freezer (much below freezing point) for ~1 hours?

I am also stuck and want to try this before sending it back to LG.

For those of you who have sent to LG, did you include the battery? LG instructed me NOT to send the battery and back cover.

Thanks!!
[T-Mobile LG G4] rid30n:
Hi all. First of all, thanks for the helpful topic it really works. I tried it today and managed to back up my files. Btw I saw that people are saying most of the phones that have this bootloop issue are with 505 S/N but mine is with 509 and I still got it (1 year and 1 month after purchase).

First I tried putting only the phone in the freezer without a battery for about 20 minutes. After I got it out and plugged the battery it started and loaded normally but just for 2-3 mins and after that it went off again. So this time I put the phone with the battery in the freezer for about 30 mins after which I just opened the freezer to start the phone, plugged the USB cable and restored all my data to my PC. But for all of this the phone needed to stay in the freezer with a closed door. Hope this is of additional help to someone and thanks again for the helpful idea :)

507 Dead

My symptoms:

"Life's good" boots to black (no looping)

Phone is turned off and plugged in to a power source: does not charge

Occasionally boot will get pass "Life's good" and then shut off (occasionally loops back once before BSOD)

Black screen of death (BSOD)

Power button unresponsive - battery must be pulled

Power button unresponsive even after battery pulled and reinserted

My story:

My phone suddenly rebooted on my commute to work this morning while waze was on and listening to a podcast. The first few reboots it got past the "Life's good" but would loop back, eventually it just booted into a black screen of death.

At work I probably attempted to boot a hundred times with two different batteries. Could not boot via vol-D+P, vol-U+P, and eventually P button didn't do anything. Ran into this post, immediately popped my phone into a ziptop bag with some silica packets and threw it in the freezer for 30min. Vola the phone boots all the way up, I manage to back up my tasker and launcher settings before it dies again. Throw it back in the freezer for another 40min, make more backups before it dies. I throw it back in the freezer for another 40min, this time I put it in a vacuum sealed tumbler and the phone seems to stay workable for a good 30min, just enough time for me to pull everything I need off of it (including my backups). I tried to do a TWRP backup but the phone died about 25% of the way through.

So I call LG even though I've been out of warranty for about six months, they take my IMEI and they offer to replace the phone free of charge with all the shipping paid for. Note there was no "haggling", they just put me on hold a bunch of times after I have them my IMEI. I just now got back from dropping off the phone at FedEx and now I'm waiting for my replacement, hopefully a 600 phone and not my "fixed" 507.

Conclusion:

Thanks OP for posting this, without it I would not have been able to grab data and my backups! I'm assuming if your phone bootloops and it's a 500 series, LG doesn't seem to have any issue replacing it (even if it's out of warranty). Sadly will be losing my glass protector but hopefully I'll get a 600 series phone.
[T-Mobile LG G4] renoob:
Freezer method did not work for me-

As I have read it is a cold solder joint of the cpu, I did the opposite- hair dryer.

Pulled battery, and heated battery area to almost too hot to hold.

I offloaded about 10g of data, backed up texts and apps, all while keeping the phone just under

too hot that it would shut down.

I got the "If it gets much hotter, it will shut down" prompt.

I have about 10 mb of files left and I will have it all.

3 out of our 5 phones with this issue- only 1 happened in warranty, and was 20+ days for a replacement.

The other 2- 1 year + 1 month. 30 days out of warranty.

LG did accept one as a return, but have yet to see if they will fix it for free.

LG should issue a blanket recall on these devices.

[T-Mobile LG G4] sbustilio:
Did you put the battery in the phone and then freeze it or without the battery?
[T-Mobile LG G4] john9250:
I'm definitely going to give this a shot. The sad thing is, all i did was google how to pull data from a bootlooping phone and this on popped up. I wish I'd have been able to take more precautions because i knew this phone would crash.
[T-Mobile LG G4] nick camel:
Challenge accepted! I'm putting mine in the freezer now. Then the plan is to boot it up, and if successfully booted, I'm gonna leave it in the freezer and sit in front of the freezer with my laptop and connect a USB to the phone (which will still be inside the freezer) :)

All of this while in the office... LOL people are going to wonder...

I'll let you know...

EDIT: Ok, so after 20min I tried booting it.. It actually booted up to the PIN-code screen and died. So I left it for about an hour... Same old problem, just reaches the LG logo and either shuts down or bootloops.

EDIT: Freezer doesn't work for me. At best I got to the PIN-code screen and then it died again. Tried the freezer up to 3hours with no luck. Thing is, the phone won't even enter bootloop anymore unless deepfrozen LMAO. Need to contact a Cryo-lab, get this thing sunk in liquid hydrogen :D

EDIT: Ok so, chanaged tactics. Hair-dryer got me past PIN-code screen. Opened gPhotos, started sync, then died.

EDIT: Tried hairdryer again and it booted... but I kept pumping it with heat in intervals so finally the overheating protection kicked in and prompted me that the phone is turning off. I'll go and argue with my carrier at their shop in the coming days...

If you want a good laugh, take a look at the comments to this video: https://www.youtube.com/watch?v=BmE26S-9NrQ

EDIT: Actually I'm gonna try the video in the weekend since LG support told me that a repair will erase internal memory.

To quote...

LG Support: Unfortunately the internal memory won't be save during service. The only way to retrieve your data is to regularily back it up. E.g. through your google account.

Me: ...or you don't manufacturer phones where thousands get a bootloop problem.

...then some kinder words about the fast support..then..

LG: I'm sorry, this was not planned.

LMAO!! Really? It wasn't

FINAL EDIT: OH MAN. My pictures are saved!!! followed the video I linked to earlier above (with the hilarious comments) but in another video a guy was saying that it probably wasn't enough using the hairdryer once. So I tried THREE times with the hairdryer... 6-7 min each time or until the overheat protection of the hairdryer kicked in. Even after that, it's not an exact science (LOL) it bootlooped once or twice but then... moment of magic. Phone stayed alive long for me to copy over all my pictures and other data.

PEACE OUT
[T-Mobile LG G4] nick camel:
Ok guys... Is it possible to charge the battery without the phone attempting to boot up. Cuz right now, my battery is drained (so I can't do more freezer experiments) and when I plug in the charger, the phone tries to boot up aaand during boot no charging takes place aaand I happen to have a bootloop problem.

Help, anyone?

EDIT: Nevermind this
[T-Mobile LG G4] Mika83AC:
I can confirm that putting the phone in the freezer vor 20 minutes worked. I was able to boot up the phone and safe the most urgend data stored on the phone, that it powered off and went into bootloop again.
[T-Mobile LG G4] Knasttker:
Oh , don' worry firend, i have a method for you to regain lost contacts on android phone , which enable to you scan portion for lost contacts on the phone with recovery tool
[T-Mobile LG G4] nick camel:
Mine needed heat. Sure the freezer helped for me aswell but not nearly as long as needed before bootlooping again.

Guys, For those who are experimenting with their phone rying to get the bloody thing to work, I'm posting a picture which shows how to boot the LG without reassembling the whole thing everytime.

Connecting the two PINs equals pressing the power button.

I'm not quite understand you, but when the files has deleted from phone , you need to restore them back as soon as possible , if the deleted files has been covered , you have not chance to restore them any more
[T-Mobile LG G4] Rascker:
Like the Android recovery app . Androiddatarecovery app , Android rescuer ,Mobiledic ,Tunesbro and more .they are good at recovering deleted data from Android phone ,

I find MobiKin Doctor from androidpit recommendation, can recover data from Android and SD card.
[T-Mobile LG G4] Krisztian K:
My LG V10 has right after 2 years the same boot loop.

I managed to back up everything by doing this:

1. Charge the battery as much you can (30 - 40 %). You might need some cool down periods (phone in fridge will help)

2. Once battery is charged enough put the phone without battery and cover within a zip bag in the deep cooler (fridge)

3. Wait a while (1 hour will do)

4. Take the phone from the fridge

5. Take also something that has been already deep frozen in the fridge and can be used as a cooling bag. I used 2 cooling batteries, but deep frozen bag of peas will also do

6. Put the cooling bag in a thermo bag (or anything that will keep the cold inside for a while)

7. Place the empty zip bag on the cooling bag

8. Put the battery back into the phone (do not put the cover back)

9. Put the phone on the zip bag upside up

11. Connect the phone to a PC using a usb cable

12. Select file transfer when the phone is asking for

13. Put another zip bag on the phone

14. Put another cooling bag (cool battery etc.) on the top and close the thermo bag

15. Transfer all your files via PC manually or with a backup tool (I would not recommend LG Bridge Backup - unless the next phone is also from LG)

16. Say good by to your phone, since most likely won't every see it running again

Hello guys,

Sorry in advance if i wrote this thread in a wrong section, however I'm out of options here :/

Everything is great and streaming works with google photos, youtube etc, however the one thing that doesn't work is chrome for android app. Whenever the cast button is available while html5 video playback, my chromecast starts to load the stream and then it goes back to the background screen :/

Anyone have faced this issue?

Thanks in advance for your help

I was reading about rooting a philips i think or panasonic android tablet . Someone mentioned that their bl is locked on it, and someone else said they had gone into some file with adb i think and unlocked thier bootloader manualy in adb. Has anyone tried anythig similar with the z3v. Im sorry for the lack of details , i will have to look that up again and see if i can get more info to explain it better. And also im sorry if this responce is not right for this bounty thread.

---------- Post added at 08:03 AM ---------- Previous post was at 07:53 AM ----------

Ok, what i meant was. Has anyone used adb, and fastboot. They did that on some forum i was readig in and then typed command in fastboot "fastboot oem unlock". Then went bback a menu or so and there was an unlock button at that point that they hit and it unlocked .Im pretty sure this has been tried, but wanted to mention it to make sure it wasnt an option with our z3v.
[Xperia Z3v General] gregbradley:
That is the standard way to unlock the bootloader and the way to officially unlock devices that have it allowed. However, some xperia devices and all Z3v have this blocked. The point of this thread is to find an unofficial way to unlock and bypass the official block on this.
[Xperia Z3v General] Samwest1:
Oh, ok. I didn't know that was the normal way it was done. I had just read about it and thought u guys would kno about it but maybe not so i wanted to make sure.
[Xperia Z3v General] thals1992:
I think I'd pitch a few bucks in if we can get interest again. This thing would be just about perfect with custom roms. Making do with Root and Xposed for now.

[Xperia Z3v General] GigaSPX:
This phone could only go so far with how things are going. I'm almost making my days with his phone numbered because of how much appeal the Galaxy S7 Edge is to me. D:

The only developers for this phone are either really busy or this is just too tough to crack without getting real help from expert developers from XDA.
[Xperia Z3v General] Tigerhoods:
so this is now Impossible due to the kernel in 5.1.1 the kernel was set to debug in 5.0.2 and now they added some extra crap to 5.1.1 so even if u revert u still have that addition to your kernel and zachpope and i have upgraded so there's no way to test it and we couldn't have it, so what would be the point. I'm assuming most of you have upgraded to 5.1.1 also. It was a lot of work anyway and we flashed z3 ROMs they didn't work it would have been nice to try a z2 ROM before we lost this as it may have worked.
[Xperia Z3v General] GigaSPX:
Well holy crap. That's already pushed my desire to get the S7 Edge now. Verizon really hates us Z3v buyers.
[Xperia Z3v General] Tigerhoods:
you might want to wait a few months for development and root. And yes Verizon hates us although this could have been the same with the z3, it just took 10 months longer to get 5.1.1 I'm not sure. The only phone this bootloader thing could be useful for to my knowledge would be the guys stuck on 5.0.2 with T-Mobile if they are still stuck on 5.0.2. And again it was a lot of work and kinda useless for our z3v =z2/z3 hybrid.
[Xperia Z3v General] GigaSPX:
Wait for development of the S7/Edge? Yeah that's understandable, and to this day, I have no idea what this "KNOX" thing is for Samsung.

Our phones are great, but it's already outdated by new and newer things.
[Xperia Z3v General] Tigerhoods:
yea development for the s7. Knox is a Samsung pay thing I believe. Giga I would seriously consider not buying a Verizon branded phone if I was you. Look at all the crap Verizon's put us through with the z3v. If I was you and I had to have an s7 I would sell my z3v for I duuno $175

And bye s7 outright if u do that and ur not under contract your line cost is $20 a month instead of 40 so either way your going to pay 500+ for the s7 when its all said and done. Its your choice if you want to risk it. What about the x-performance are you not interested in that.
[Xperia Z3v General] GigaSPX:
To get the best coverage, it has to be with Verizon. A full price of the S7 Edge is $792 purchased through Verizon, which breaks down to $33 a month for two years. Upgrading with them will opt to help get 2 additional gigabytes of data onto my family plan per line upgrade forever. So I'm still trying to decide whether I'd purchase one off of eBay to save at least $100, or see it long term that I get more data and all that.

Really though, I'm not going to be upgrading anytime soon since I don't want to trade my phone in. The whole trading in for whatever value of it is left is really stupid since I'll lose my money there. I might as well keep it as backup or give it to a family member in need of a phone where they can't afford one overseas.

Do you have any certainty the Xperia X Performance will be compatible with Verizon's network?
[Xperia Z3v General] poolchamp:
It is almost certain that the X series will not be CDMA compliant. From what I have read, it looks like Sony is going carrierless with their release. If that is the case, GSM is the only option. Does AT&T not provide sufficient coverage for you? My grandmother lives out in the boonies and she still has AT&T coverage out there.
[Xperia Z3v General] thals1992:
Can we leave other device discussion to somewhere else? If no one is willing to get this thing unlocked, I'll take my money elsewhere to get someone else interested. Not dogging anyone, but everyone is totally off topic. I will have to catch some one interested with CM on this device. I don't think you can just flashing stuff not built for the device.
