I have perform a factory reset from android settings in order to sell my G PRO, and after the factory reset and the automatic reboot, device boots in recovery mode (CWM), i tried to turn off and boot again or to use the advanced menu to "reboot device", still go directly into CWM after the LG logo shows off.
If it's help, i followed this tuto to root + install CWM on my device : http://www.technostall.com/lg-optimus-g-pro-f240-root-and-install-custom-recovery-image/#

OK, my problem was Windows 8.1... The phone is well recognized by LG Tool under W7, but now I have another major problem, at the last step, when the tool begins to flash the rom, it goes until 5% and then this popup box blocks the flash "battery level is low and upgrade is unavailable"
I have reload fully my battery (I plugged it into the G PRO dock)... still the same message.
Any help please ?

Did you manage to resolve the issue? I am just having the very same problem and a bit lost and cannot risk flashing anything right now.

Hello, I would appreciate your help because I flinched and my tel ugly now this only in the LG logo screen. I wanted to update my original rom Phone factory and downloaded the latest version before upgrading but I did not wipe data and When there finished the process gave an LG IMS error stopped working this type, and there Could not get into hard reset on the way, OK up here but then I Decided to reinstall the rom again to see if it would correct the error and then I installed the previous version I had downloaded it and my phone is so in the logo screen. If I try to instal the updated rom, would be more risk? And I wonder if I can not like the ace debugging would access via adb and make wipe data factory reset only by simple USB connection? I can not I do the code by turning the volume down and holding power button goes not into hard reset the screen goes black and comes back on the LG logo... Pleaseeeeee help meee!!!!!!

Bootloop after Xposed install, Hard Reset not working

Hi there,
i rooted my G3 using Towelroot and all worked fine.
Today i installed the actual Version Xposed Framework and after rebooting it entered a Bootloop.
So i tried to Hard Reset my G3 but when i confirm it the Android with the Gaers show up for a second and then my G3 keeps showing the LG Logo for a few Minutes till i disassamble the Battery.
Next step i try is to flash a firmware in Download mode, but i cant get the Drivers to work... =(
Someone have some hints for me?

Have you choosen ART modality?

If i would say "what the hell is that" ... would u slap me?
No.. i dont have chosen that..
Bigger problem is that i dont get any usb driver working for firmware update in Download mode.. =(

OK... i managed to get the drivers working.
But further Problem ist now that im not able to flash anything on my device...
Neither the TOT Method, nor updating with the Original LG Support Tool is working...
Support Tool tells me my Model Number and that my Version is most actual.
If i update anyway it stucks at 4% and tell me it cant connect.
TOT Tool tells me that my Version Number is not correct... but it is..
With the KDZ Update Tool it stucks at 4% like the Original method.

Same problem here
Any one can help us?

Solution
Hi there,
the Problem was my PC...
I was on a Windows 8.1 64bit.
Switched to a Win7-PC and all is working fine.
You should try to use the Original LG cable, or another "Original" Cable and connect it to a USB-Port on the Back of your PC (directly to the Mainboard)
On a blank Win 7:
- I installed the LG PC Suite
- Updated the PC Suite
- Connected my LG in Download Mode
- Let the PC install all drivers,
- Disconnected the Phone
- Downloaded the actual LG Mobile Support Tool
- Let the Support tool do the work
After this i got my first OTA Update and its working like a charme

#Solution# Flashed Wrong Model Rom To D852.

So Long Story,
Monday November 24, I Changed Out Battery Go To Restart Phone, Phone Wont Boot Stuck On LG Screens And Constantly Retrying. Tuesday Night November 25, I ReInstall Factory Firmware For G3 D852 – With Success – Phone Working. Wednesday November 26, I Decide To Root & Install TWRP – With Success – Phone Working No Issues. Friday November 28, This Is Where Sh*t Hits The Fan! I Get Crazy & Attempt To Install ChupaChups Lollipop Rom With TWRP – Seemingly Successful Install But After Reboot Wont Boot Stuck In Fast Boot. So I Attempt To Resolve This Following Other Forum Posts Using FastBootOV – WITHOUT Success – Now When Attempting To Boot Phone LG Screen Comes Up Top Left Corner Says “ERROR Boot Certification Verify” Below That Says “590 Secure Booting ERROR!” Then Black Screen With Flashing Red & Blue LED. I Attempted To ReInstall Factory Firmware For D852 With LG Flashtool Attempt Fails Stating Wrong Model Number – Phone States On Screen Near Bottom Now D855 Ver5.0 Below That D85520A.
Finally Success With Phone December 28, After Countless Hours Trying to Find Some Shred Of Info To Resolve This Including Posting Here For Help Without A Response. I Proceed To Attempt To Reinstall Factory Firmware For D852 - Failed Same Result Wrong Model Number D855. Actual Model D852. I Then Decided F**K It Ill Install D855 Factory 32G Firmware UK Version Why Not? At This Point Phones A Paper Weight In This Time Had To Purchase Another Phone (So I Dont Lose My Mind) - All Available Information Points To Send In For Warranty. So I Do So Again Attempting To Install The D855 UK Firmware Failed To Install Using LG FlashTool, This Time Stating Partition Errors. So I Find After Random Searching & Random Reading Of Everything LG G3. I Find A Generic LG G3 DLL File (LGUP_8974.DLL). Using The Generic LG G3 DLL & Factory Firmware D852 With LG FlashTool - This Time Working Up To 89%, Phone Reboots Shows Large 2, Crossing My Fingers Waiting For The Large 3. What Actually Pops Up Is A Large 0. I Attempt To Reboot Phone Goes To Mini OS, Set Phone To Reboot Normally - AND SUCCESS!!!!!! Factory OS Boots Up, The Usual YADAYADA Setup.
So Thats All, A Long Winded Story BUT Now There Seems To A Cure To Flashing WRONG Model G3 Roms To Your Device.
Hope This Works For Everyone - I Have Devoted Coutless Hours Trying to Avoid Sending My Phone In.
Good Luck!!
I Am Unable To Post Download Link For Generic DLL File Since I Am A New Member.

I did the exact same mistake with my D852 and my LG G3 says my phone is a D855 in the firmware update, I will try this out and hopefully it works!!!!

Man, this was a long story but I am so glad you have posted this. I always wondered what would happen if I by mistake flash the wrong file (diff model), and now I know. Can you please send me the link to the info and the files, just in case I end up where you were (email: elmspace at gmail dot com), I would appreciate it.

Thanks man. I was just wondering what is going to happen to my LG g3 D856 variant if i flash D855 kdz. Now um not gonna do that. Let's not flash any rom. I successfully rooted and am using D858HK twrp ( yeah D858HK) successfully.

hi hi
hi hi same problem after i want to root the phone my LG G3 D852 my phone stuck on fastboot mode blackscreen ,my pc see it like Android bootloader Interface BUT no other programs see it try lg flash tool or lg repair tool or cmd command nothing they don't see my G3 HELP HELP PLEASE

Sorry for the no response on this problem , got the same problem last year by flashing the d850 rom to a d852 model but this solution is not recommended. It works sometimes (was working with mine but I bring it to LG because the motherboard dies for no reason after one month of use lol) but the installation can go wrong and destroy your motherboard.
Envoyé de mon LG-D852 avec XDA Forums Pro.

Holy hell I ran into the same issue and spent countless hours getting my D852 back to life after flashing the wrong ROM. I found this and sure enough it came back!

plss help

That's what I was thinking but would rather do it officially, any ideas why my phone does not have the OTA option?

any help?

Have you tried the official LG Mobile Support Tool and the LG PC Sync software?
Try the support tool using the update recovery option.
Good Luck!

Thanks for your reply, Tried LG PC Suite get message "latest version: D85510A"

OTA is kinda glitchy on G3. Upgrade via flashtool, you won't lose warranty or anything.

Just do "Upgrade Recovery" via LG Mobile Support Tool. It's in "Options" section.
Wrong software installation causes this. This operation will fix OTA updates for future too.
You can download LG Mobile Support Tool here;
http://tool.xcdn.gdms.lge.com/client/app/B2CAppSetup.exe
a Tip; Nevermind if program says there's a software update for your device.
Another tip; Connect phone in download mode
Attention; "Upgrade Recovery" operation will wipe your phone. So, don't forget backup your data.

Your data had to lost if you ran "Upgrade Recovery" successfully.
If you want, I can help you via TeamViewer

Hi, Thanks for all the help, I may need your help through teamviewer, these are the steps I did:
1. Switched the phone off and held the volume up key and plugged in usb to enter download mode
2. Firmware update screen appeared on phone after download mode screen
3. Support tool connected to phone
4. Clicked on options update recovery
5. The tool downloaded and installed update
6. Phone booted up with no changes.
Any problems with this procedure?

also when flashing it says something like lg d855 4.4.2

There's seems no problem with procedure. It's really weird.
Is your phone D855?

yes

You could try downloading the LG Flash Tool 2014 from here on XDA and downloading a KDZ for your phone and flashing like that.

SoftBrick with root - Help!

Please, somebody help me... I have a SM-T705m which I have rooted with android kit kat. After some months I got updated to the Lollipop and it was running ok, but it wasn't updating via OTA anymore.
Well, it happens that today I reset the tablet to the factory mode to sell it, but it was without unrooting, and then it got stuck on the screen saying "just a sec". I went further and tried to download some versions of the firmware and install it on the Odin3 without knowing exactly the number of the version Cause I couldn't turn on the gadget to look. I just got any firmware with the name of my model and my location (Brazil) on the site Sammobile.com....
But bang.... Now I can't turn it on because it is looping on the logo screen.... I tried to download the lollipop firmware and the kit kat..... Could somebody help me? it is looping and I need to sell it tomorrow. I would really appreciate it.

Boot to recovery POWER + VOL UP then factory reset.
Reflash the stock LL firmware.
