[Q] LG Optimus 4x HD gets stuck on boot animation,please help

Hi All,
Sorry if this is a duplicate but everything I have seen at least has not helped me further.
I wanted to root my phone yesterday and everything (tutorial here with o4xr) the went well till it installed busy box where the computer froze and then shut itself down and so I tried to turn restart my phone normally. Now its stuck at the bit where the LG animation is and goes no further.
Here is what I have already tried:
Rerunning the o4xr/root method again
Hard Resetting (selected and running all options available)
LG Service App (windows) -> always fails on communicating with device... works up until that and I do see the SW Ugrade splash.
My version is the EURO Open v10h or something like that.
Please help me fix... This is the first phone I havent been able to root, any suggestions?

It worked this time. I guess I was so stressed that I accidently downloaded the wrong firmware. Thanks alot for making me try that route again plus I have a backup now should this happen again.

Nothing like a brick to freak you out with your brand new device, luckily you got it sorted

Not hard brick, but soft brick. There is a huge difference. Just for your info.

from where can I download .kdz file and the main site is telling
ACCESS DENIED
http://csmgdl.lgmobile.com/swdata/WDLSW/LGP880/AAREBK/V10b_00/V10B_00.kdz
is there any other links for the .KDZ file to be download from
thank you

Security Error LG G4 (Bricked?) i think

i was freezing and uninstalling apps last night and must have removed something critical to the operating system. Now my phone will only load the Security Error screen with (authetication failure) in small print. i've been told that my phone isn't bricked but that i need to reflash the image. Im currently in Download mode but don't know what to do next. i have the rom image that i initially rooted the phone with. Thanks in Advance. peace

same boat ... but i don.t have the system.img in my storage

Try this link http://forum.xda-developers.com/g4/general/guide-recovering-bootloop-twrp-t3167361. Try adb pushing the image to your phone if it still recognize the connection
adb push system_image_name.img /sdcard/system_image_name.img

Lg has a tool you could use (it restores the firmware (plus upgrade))

If all else fails, try to restore via the TOT method. Instructions can be found here

Any luck?

I tried to root my ATT LG G4 H810 running H81010I using this procedure: how-to-root-the-att-h810-lg-g4 page at androidexplained.com ... I now get a "Security Error" with "Authentication Fail #11" everytime it boots up and then shuts down. I believe I used 10g instead of 10i version (which I downloaded from the root-tmo-vzw-intl-variants-soon-root-lg-t3164765 page at xda-developers.com/g4/orig-development/), but now cannot seem to use any of the recovery methods because I do not know how to push the proper [system.img] file to the root directory. I can get to the "Firmware Update" screen but the hard reset function does not appear to work.
Can anyone help?

Hey hey i'm also having an authetication error with my LG G4 on sprint. I HAVE NO CLUE WHAT TO DO THO. Sorry for the caps i'm seriously freaking out because no where on my phone in the settings could i find out if it was LS991Zv4 or Zv5 or whatever i was so i used the method that seemed to work for most people and now i'm just sitting here crying because i just GOT this damn phone ;w;
i can't find a KDZ file for my phone anywhere ;w;
and the TOT file requires me to log in to the LG Flash tool? I'm so confused ;w; rooting motorola devices back in the day wasn't as troublesome as this ;w;

Download LG Flashtool zip, install LG Flashtool ( dont open the program) in the unzipped files copy paste mega.dll, copy this file to C:\LG\LGFlashTool and replace de original file... after that Run the program and you was to able to flash TOT file

Also stuck
Hi, saw you helping a lot of people. Hope I can be next, lol. I'm attempting to repair a botched root attempt on H8110. Apparently, the first rooted image was not the correct one. The phone is stuck in a boot loop with "Security Error". I can get into download mode, but can no longer USB copy the correct image over. What steps can I take to get back on track? Thank you!

My phone won't even really turn on, the welcome screen comes up and says that there's a security error, and stays on that screen. I don't want to do a hard reset if I don't have to

Well you're gonna have to use LGUP to restore using the TOT.

[XT1068] - Hard Bricked while downgrading - HELP!!

Recently i installed the soak test of Marshmallow update. but after that i decided to go back to stock kitkat by using Easy KITKAT installer http://forum.xda-developers.com/moto-g-2014/general/windows-tool-moto-g-2014-xt1068-dual-t2983295
while i was downgrading my phone automatically TURNED OFF!!! :crying: . After that i tried to restart my phone. But it didn't restart. i plug the wall charger in, it didn't charge. i tried to connect it to pc. nothing happened. Only there is a plugging sound in pc. In device manager my phone is recognized as QHSUSB_BULK with yellow exclamatory sign. :crying: . i can't flash another rom because
Stock Recovery isn't working.
Yesterday i took my phone to service center, they told me they can't fix it. i am very frustrated right now.
I couldn't find any solution in the internet and in this forum. So this is my last try by posting in this forum.
IF ANY ONE CAN HELP ME, I WILL BE VERY MUCH APPRECIATED.
HELP! HELP! :crying:

There have been warnings everywhere to not downgrade the bootloader after going to Marshmallow, the Kitkat easy installer most likely did that. There's nothing you can do, other than get a new phone.

I had the same problem. Like the guy said... no other option BUY a NEW PHONE! At the moment that's the only option available. Everyone is waiting with eager anticipation for 6.0 update, if it's so good why are so many people going back to their previous OS version and bricking their phones? Motorola are not prepared to help at all claiming that downgrades are not supported and will never be supported. I go a new (2nd hand) XT1068 and I'm on 5.0.2. I WON'T be updating again that's for sure!

Guys a good news is the required mbm ci files have been released for moto g 1st gen and people have been successfully reviving their dead phones... Just keep hope and continue discussing in forums so that we get a solution as well... I am asking help from a couple of developers... hoping for the best. Cheers!! : )

. That's great for people with 1st gen phones. Lenovo / Motorola have said repeatedly on their forum that are aware of the problem but that they have no intention of releasing the required files for The Moto g2...

what is the proper way to downgrade from 6.0.1 to 4.4.4? or there is no way to downgrade. I also want to go back to kikat but there is no proper tutorial on forum so that i afraid.
my bootloader version is 48.86 !

Bricked XT1068 after failed OTA

I recently tried to install a lot of ROMs, with few success because I'm a beginner at this kind of things. I still managed to reinstall completely a stock KitKat version, and tried to do the OTA update to Lollipop. The screen turned down when the update reached approximately 60% and I can't even restart the phone in bootloader to restore with adb since. Can someone help me or is it helpless?

Same here.
I have a xt1068 and I was on MM, but after found that gps was not working properly, decided to downgrade to Lollipop.
The downgrade worked fine, but then came the OTA stagefright update notification and I tried to install it.
It was on the recovery screen, in the middle of the update, it suddenly blacked out and made no response to charging ou power button. I cant make it into bootloader, nothing. Dead.
Help!

same thing happened to me

So sad

Same here. I tried following some tutorials on bricked phones, but my pc won't even recognize the device as they say it should. Can someone help us? I'm about to go out and go to a technical support store, but I'd like to try on my own first... Someone there to help me?

Rooted one plus 3t with corrupted recovery stuck on bootloader

Hello everyone. First of all, sorry for the long post.
I just bought a OnePlus 3t three days back. Updated it to oxygen 4.1.3 and then rooted it as well. Everything was working fine. But then I decided to downgrade to 3.5.4 since I wanted to try out Xposed Framework. So I downloaded the OS from OP Support website, and went to twrp recovery and installed the os 3.5.4 from the internal memory of the phone. It seemed to install properly but when I rebooted the phone, it started asking for a password. I tried every possible combinations of my passwords but to no avail. I saw online and found some video where I was supposed to flash a new recovery which I did. After that the phone got stuck in Bootloader. There is no bootloader and recovery version detail available on this screen.
If I try to restart the phone it gives me the following error, "Decryption Unsuccessful - Your phone storage has been damaged, unable to read data stored in your phone! To continue to use the phone, you need to reset the phone." There's a button at the bottom of the screen to Reset Phone. When I click that the phone goes back to bootloader mode.
Please help me out here. I have no clue what to do right now. I have tried flashing several recoveries but they give an error "cannot determine the image filename for abcd.img"
Any and all suggestions are welcome. Thanks in anticipation.

Thank you for the reply. I haven't yet tried it, since the computer recognises the phone just fine. It even shows up in the fastboot devices list in cmd. Maybe, I should give it a go.

Ok so I did manage to reinstall twrp. But I have no idea what to do next. Any suggestions ?

I managed to fix it. After the twrp recovery was installed, it started asking me for a password. Which I tried and didn't work. But then I just wiped the phone and it went back to factory settings somehow.
Now the phone is back to oxygen 3.5.4 and works fine.
Hope this can be helpful to someone else.

I'm glad u fixed it
Can u please post the correct steps to avoid this issue in the first place .
I'm on 3.5.4 but I may want to try latest versions and come back to 3.5.4
