G PRO F240L stuck in recovery mode after factory reset

Hi there,
I have a problem with my G PRO F240L...
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/#
Thank your for you help

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!!!!!!

[Q] lg mobile support tool

HI , first post , so here goes....have an old optimus g which i tried putting recovery on it....when phone rebooted , it had the secure booting error on it ....i went to the xda unbricking guide and have been stopped by the fact that the lg mobile support tool does not see my phone , and after i have downloaded and installed the drivers for my phone the lg optimus e973 .....
Verify that your phone is recognized and connected by checking the LG Mobile Support Tool. The text "Waiting for connection...." should be replaced by your model version LGE975 LGE970 or similar
..........i think i put the right drivers because i looked for them under the driver options for my phone ...but it still will not recognize my phone ...thanks for the help ...if any....have a great day.:cyclops:

more info is better than none, what did you do to "accidentally brick" your phone? and if you are stuck in download mode you could try the lg mobile support tool and re load the rom for your device.

READ completely, including the link in 4 before starting!!!
download the tool using the lg d851, under t-mobile. the tool is generic, and can be found at lg.com under support/downloads
1. install LG Mobile Support Tool
2. run Tool, it will query lg for updates and do so if needed.
3. Install USB Driver (dismiss if you have done so already)
4. follow this process: http://forum.xda-developers.com/showpost.php?p=51268802&postcount=21 (use 5. below to put into download mode, not vol up and down like the link states)
5. with your device off, hold the volume up button while plugging in your USB cable with the Tool open.
6 you system will recognize the device and configure drivers, this will take a minute.
7. continue following the link in 4.

Does this method work? Or is there any other fix yet?
Thanks in advance!

no i did not fix mine yet i am on tmobile am not sure if they will consider return am still within retun policy

hey guys, don't ask for a different fix if you don't bother to explain how your phone got stuck in download mode. as for does this work? Why don't you try, it's the same tool used to upgrade firmwares instead of using OTA, and the link included shows how to get the tool to download the file (if it sees the same/current f/w it does not download the firmware) and you have nothing to loose, and this method is often used to recover from "soft bricking" your phone.

i was restoring my LG G3 to stock through the lg flash tool .....when i got through with it and restore was succesfull. somehow i forget the usb cable plugged through my pc usb port ...then connected my lg g4 that is where the flash tool got my Lg g4 on Downloade mode ....i tried all the methodes somehow i think the recovery is messed up .....i can get to the recovery through the button but it reboot straight to the download mode ....thanks every one for their support

Good luck, if you did the kdz there is the LG flash tool

don't think it's out yet, however my statement was somewhat incoherent. I meant to say if he had the kdz, he could use the flash tool to recover his phone.

Yea, at this point there no way to fix this without a kdz that I know of.
Call LG and tell them you need the kdz to restore your G4.

i was lucky, i had flashed twrp before my phone soft brick..

I got an LG G4 which is stuck on lg screen. When I put it in download mode, it shows download mode for a few seconds and restarts. I was trying to flash ZVB over ZVD and it ended up like this. Model is ls991 . Any help would be really appreciated!

Anyone got any idea? The whole thing started with getting rid of the Genisys rom ... I did not like it ... I thought I was going to bring it back to the stock, but then LG Up wrote an unkown device ... I thought it was flash with lg bridge ... that's what I lost. .. has removed recovery and has stopped updating at 16% ... since then it is only download mode I tried to update but failed with all three programs ... LG up to start - unkown device, LG bridge stop at 16% , LG Falsh Tool 9% ... sorry for my english

Bricked!!! Help me out please!

I'm a newbie and don't know much about phones. I rooted my phone for the very first time and was about to install CWM.
I've an LG Optimus G Pro F 240K.
I downloaded an app namely Flash Optimus G in .apk form and installed it on my phone. I tapped on Flash and the screen read "SUCCESS! Now re-boot you phone into recovery." I tapped Reboot into recovery. That time and now, i'm numbed. The phone isn't responding at all. I'm using Windows 10 Pro. In device manager, an exclaimed mark icon gets visible when i connect my phone.
The device name is QHSUSB_DLOAD.
I've downloaded official stock firmware 4.4.2 kitkat. When i use LG Flash Tool, it says your device isn't connected to your computer.
What should i do???

Or downgrade to Windows 8.1 and then restore by KDZ

qhsusb_dload means you´re in qualcomm mode, and also means that you´ve killed phone boot. from what I know, only medusa and riff boxes can fix it.

Only Download Mode for my GPAD 8.3 V500

Hello,
I have a lg g pad 8.3. Today I've tried to do the downgrade Lollipop -> Kitkat, but something wrong and I have the boot logo restart. But I've put my G PAD in download mode and now I'm trying to install various version of stock version through LG Flash Tool. But on my Windows 10, I receive the error "LGUserCSTool LG Mobile has stopped working........", while on my Windows XP pc, the .kdz of the version 30a.kdz stop the installation at the 95% and the LGMobile Support Tool tell me to retry the installation, while with the version 10b.kdz, finish at the 45%.
What I have to do now?
I see only DOWNLOAD MODE on my tablet, If I shutdown the tablet, reappears the Download Mode, no LG Logo.
Sorry for my bad english.

I followed this guide but used the 10b.kdz instead of 30a
http://forum.xda-developers.com/lg-g-pad-83/general/tutorial-korea-v30a-how-to-flash-t3076576
I noted that using 3GQCT worked fine (but required a hard reset)
CDMA caused "LGUserCSTool LG Mobile has stopped working"
