my g3 encrypted itself - T-Mobile LG G3

like the title say my wife g3 d851 encrypted itself for no reason.is on firmware 10m
we put it on the charger when going to sleep and in the middle of the night the phone was on with a withe screen asking for pin/password to decrypt we never activate encryption on the phone in fact we don't have no idea how to do that,anyway that phone never have a pin or password we don't like put in pin or password to use the phone is too much hassle just to use a phone
well the point is that now is stuck on that screen and no matter what we do nothing fix it.
thing that i try
factory reset on normal recovery because the phone never was rooted or custom recovery installed
try to flash kdz it flash but when turn on again it stays on the same firmware never really installed
try flashtool with a tot and it fails on 6% with an error cant erase command or something like that
right now i turn to the experts here because i search everywhere and no one knows or have a way to fix it other than to returned to tmobile something that is impossible at this point because i dont use tmobile and lg warranty is already expired
please any help to get this phone working again?we already lost all the data on it but at least we would like to save our phone.

anyone please

it seems that im the only one with this problem

[Q] No Boot! No LED Signal

So, i tried changing my roms from Paranoid Android to myonev 9.5
And i knew i had to flash boot.img but then i thought I'd do it after flashing the rom (sorry im a noob) which happened to be a graaaaaave mistake
Now my phone doesnt switch on to bootloader nor does it show the charging LED!'
I have a primoU device. Ive googled aroud and found out that it could be a hard brick and the only way is to give it to a service centre..
But the problem there is i live in INDIA and we dont have much service centres here, the closest one is around 400kms from my home :/
So i wanna really make sure that is it worth travelling all those miles..
PLUS, My warranty expired 2 months back :crying:
I wish somebody helps me here, i will do ANYTHINGGG

Try reverting to stock with a stock backup you'll find that on xda ... of your phones not booting into bootloader manually try using the all in one kit..it should have such an option although i didn't try this... If u can boot in bootloader then there's 99.9% chance that ur phone will come back to live
hold your power button until the screen goes off
then hold down your volume down button until u boot into bootloader
if it doesnt boot, try and try again
if u can boot into bootloader, the rest is easy

Thanks for ur quick reply
No matter how hard i try it doesnt boot in bootloader.
I tried the all in one kit, it doesnt detect my phone..
My pc detects it as QHSUSB_DLOAD

hmmm then im sorry to say but i think u have bricked your phone :crying:
no choice but to send to hTC
is it this easy to brick?
one small error?
arent there any drivers for this qhsusb thing? so that it can detect my phone and then i can adb it to bootloader?
Sorry mate then I'm afraid it's bricked but still you should keep trying put the phone in charging even if its not showing led signal.. Then try again to boot into bootloader...maybe it helps..coz it should not brick so easily:fingers-crossed:

Isi it possible that i allow it to drain the battery and then it boots by itself?

Actually it is a very good idea i myself did it once .. but the difference was that screen was struck on white bright HTC screen taking a lot of battery so it got discharged in 10 hrs but just now it will take a lot of time .. so i don't think you have that much patience...
That happened to me too, but that's not a brick, that's just stuck. This dude's phone is badly bricked, only way would be to find a driver for QHSUBS_DLOAD but I don't think it will be easy to find as all htc devices have this problem, someone would have already found it by now

[Q] HELP! My Xperia Play Died!

Help! I think My Xperia Play died on me! Here's what happened. It may be a long post but PLEASE bear with me. I really need your help guys! My phone was just lying around on my desk and I decided to use it and was surprised because it won't unlock. So i thought that my home button was just malfunctioning and tried to slide it's game pad as it unlocks the phone by itself but still no respond. So I thought it turned off by itself and when I tried to turn it on, it won't turn on at all because there's no short vibration. Usually when we turn on our device, there's a short vibration right? So I removed the battery, placed it back again and turned on my phone and at last there's the short vibration. But after a while I noticed that the boot splash hadn't appeared yet. I waited for a couple of minutes but still nothing happens. When I turned it on again there's the short vibration and that's it. So I searched for solutions here on XDA and on the web and I tried almost all of it. I flashed it back to it's stock firmware using Flashtool and still the same. I tried using PC Companion and Sony Ericsson Update Service but still to no avail. I also relocked it's bootloader and reflashed everything again but nothing works. So I gave up because I thought it might be a hardware issue but I didn't drop my phone or anything so i don't know what went wrong.
Then the following day I decided to check on my phone again and to my surprise it's back to normal and I was really glad about it. So I didn't flash any custom ROM and Kernels because I'm afraid that it might screw everything again. I just rooted it and completely debloated it and installed init.d support for stock kernel. I flashed CrossBreeder and RTMixManager and modified it's systemui for quick panel and battery % mod. I also flashed custom boot animation and that's it. I was happy about my phone because it seems all is well.
But yesterday when I was about to use my phone, the same thing happened again! I tried to redo everything I did all over again but still nothing! I can still use it in flashmode and fastboot though. I also tried entering CWM Recovery. After I turned on my phone I spam pressed volume down and blue LED showed up with the vibration if you enter recovery mode but there's no display. Can anyone tell me what's the problem? It might be the flex cable or the digitizer but I don't know. Has anyone encountered the same situation as mine? Please help me! I don't know what's wrong with my phone!
P.S. I can't send it to Sony Centre as my warranty is already expired. My only option is buying a new Xperia Play. Because I browsed for replacement parts on the web and they don't ship it directly to my country and it costs too much if I have it ship to me indirectly.
You have a hardware failure, I see that right now is very common, you will need to replace the automatic light sensor, to get it working, or if you don't want replace it, you will have to switch onto JB, because it has ALS disabled by default.

Try restoring with stock rom.
1. download the latest firmware (http://lg-firmware-rom.com/)
2. Follow the below thread for the steps to install it.

Had the same problem too, but every method I tried didn't work. So I used the warranty for LG and they're repairing/replacing the phone. You need to email or talk to a LG representative.
The only thing you have to pay is shipping and the rest are free.

I have the same issue (hard bricked g3) but this definitely isn't under warranty, I got it from a friend cause I figured it'd be soft bricked, but nope it's completely unresponsive, besides QHSUSB__BULK
Ummm, tried formatting what? There is factory reset, restore, but formatting?
Did you try KDZ flash or TOT flash?
If one fails, try the other.
KDZ wouldn't work for me, but the TOT flash method worked like a charm to flash my D852.
If you can see ANYTHING at all on your screen, recovery menu, download mode screen, anything at all, then it's very likely your device can be fixed.
But if you can't see anything whatsoever on your screen, like no recovery screen, no download mode screen ect then it's hard bricked and must be repaired by the hardware vendor.
EDIT: Here are a few other common reasons for failed flashing:
1. Make sure you're using the LGUnitedMobileDriver
2. Try a different usb port (front and rear usb ports can act dramatically different from eachother).
3. Try a different usb cable.
4. Try a different computer to flash.
I just got my phone repaired from LG and I recieved it two weeks after I sent it the phone to LG. They repaired my phone but they deleted everything

you could do 2 things.. one download KDZ use LGUP flash it and see if it was software related or something went wrong at flash.. if it keeps doing it then it has the bootloop issue.. and need to be sent back for repair....can you provide your first 3 digits of your serial number...?

yes it is its pretty easy... . file is big though... download kdz for you variant.. what android you are using.? MM or were you on stock LP.?
well i think since your phone is from 2015 august. that bootloop was supposed to be fixed by then. but newer phone are still getting hit by the bootloop.. but be aware unlocking the bootloader voids warranty.. some been lucky that phone were repaired some were denied repair..

if you have warranty send it back...but if they find out its unlocked they may deny repair.. you must pay for it...
this will make it boot but it will make it slow. as it disables the main cores...

Going to give this a whirl now mate, thanks.

[H815] Stuck on lg screen, no bootloop, access to download and recovery ok [SOLVED]

Hi,
I've searched over xda and google before but haven't found anything relevant so I've decided to post my own problem.
My G4 freezed unexpectedly while listening to music, I had to remove the battery to put it off.
But it never passed the LG logo again.
So, i've been stucked on this LG logo, looking for an answer and found about this hardware issue but I'm not certain to get the same error.
It's not a bootloop (even if I sometimes got stuck in bootloop while trying everything to revive my phone), I have been able to get to the download mode and TWRP (which I don't have anymore because I went back to stock using LGUP and LG bridge), even though I hardly get to the download mode now (I sometimes manage to do it though). I've also managed to save my data when I've managed to enter TWRP (plug in, remove battery, push volume down + power while putting battery in) which, people with hardware issue haven't, as far as I know.
I've tried everything I could and wouldn't even be able to describe it all.
Do you guys know how I could be sure if it's hardware or software related ?
Last try: update via Lg Bridge, succeed but still stuck on LG screen.
Thanks a lot !
Flash a lollipop kdz via LGUP, then try the ILAPO (works only with lollipop, no marshmellow) metod, there is a thread on xda.
There is a video on youtube too

Thanks, I'm going to try this and let you know !
I gave a look on what you've suggested, but is that going to let me use the phone or only backup ?
From what I understood (and I might be wrong), this only allows to backup because the phone would be worthless...

You'll be abble to use the phone, but it would be slower duo to the fact that with ILAPO you disable the "2 more powerfull" cpu cores... this metod let only 1 core active from the other 4, if you want to use the other two you have to gain root permissions and install an .apk to reactive the other 3. It's a litle triky but better than nothing I guess ��
PS: if you dont want to deal with all this bulls**it send it to LG
Same problem
This morning my Lg G4 also got stuck in boot Lg screen. Did you manage to fix your issue or got the data backup ?
sometimes flashing stock LP firmware fix it.. sometimes you must send it back to LG for repair..

I managed to backup, it's a weird trick and you need to have TWRP installed I guess:
- Remove the battery
- Plug your phone (I used my laptop but I'm guessing it also work directly from the charger)
- Push volume down + power
- Insert battery holding those buttons
I managed to enter TWRP and backup with this.
It didn't work at first, I had to try it several times.
I also read you have to keep holding volume down + power until the phone reboot itself once, and then you get access to TWRP but I tried so many times differently I don't remember which one worked best. Anyway, it worked for me that way.
I didn't fix the issue and I sent it to LG... I'm so frustrated, it's been 10 years I'm into this stuff and I always managed to fix everything
Hi guys,
So my G4 just came back from LG, they replaced the motherboard and that's it... A bit disappointed to not having been able to fix it myself but at least, it worked.
I didn't have to pay anything since it was a hardware defect, LG took care of it.
Thanks for those who tried to help, I hope this post would be useful for some with the same issue.

So my G4 just came back from LG, they replaced the motherboard and that's it... A bit disappointed to not having been able to fix it myself but at least, it worked.
I didn't have to pay anything since it was a hardware defect, LG took care of it.
Thanks for those who tried to help, I hope this post would be useful for some with the same issue.

I'm having this same issue out of the blue. Is your serial number one of the infamous "before 509" ones? I'm on TMo with the H811, so it may not be similar at all....but I'm at my wits end. I've never had a spontaneous boot loop happen to me before now. It was always something I'd done.

Indeed, my serial number was 505 something.
I've been there too, if it's spontaneous, it must be this hardware defect...

Interesting... Especially since mine was a 509 or something. I guess they missed some units. Oh well, I just JUMP'ed early with my TMo plan to the G5. That was my second G4 after a similar issue 13 days into owning the first one back in November. Having your phone spontaneously die is quite a fun way to spend your anniversary -____-. I wasn't about to give that model a 3rd try. Thanks for replying.
