Exclamation [Q] Problems with flashing LG firmware

Hello. I've searched the forums and looked at guides and people with similar problems previously.
I've soft bricked my phone, stuck at:

Secure booting Error!
Cause : boot certification verify.


I rooted it using the E980 universal rooting tool from giantpune from ballshanglow's post. I then unlocked it using FreeGee 1.10, installed TWRP 2.6.1.0.

Upon reboot, the phone was stuck with the above error. I have downloaded the relevant .kdz for my phone, installed the USB drivers and the LG flashing tool. I have uninstalled and reinstalled the drivers (trying out different versions) and also tried various versions of the LG flashing tool (KDZ_FW_UPD_EN & FlashTool.1.0.54). I have also tried to use LG's provided software to recover my phone.

The furthest I've been able to go in the recovery/stock-firmware-flashing process, is the device check. Despite have 99%+ battery according to TWRP, I still get the error that my phone (in download mode) has low battery. Other times, the flashing tool freezes up and becomes not-responding after I get an extract error, or after I click 'Reading phone information'.

I've tried everything I could find. I've also attempted to flash a custom rom, but I get:
Assert failed: getpropr("ro.product.device") == "geefhd_att_us" ||
getprop("ro.build.product") == "geefhd_att_us"
E:Error executing updater binary in zip.


I'M F***ING STUCK. I'VE TRIED POSITIVELY EVERYTHING I COULD FIND.
Is there anything you guys can suggest I try before I send it to LG to have it returned to stock?

Thank you very much, and sorry I'm a noob. I tried.

I experienced exactly the same with my E986: bootloader unlock+installing CWM recovery with "freeGee".

It seems their bootloader unlock is not good.

Flahing with r&D tool is interrupted with this "low battery" message.

help!

Dude. I fixed it. Apparently, I just didn't leave my phone to be connected to the computer long enough before beginning the recovery/restoration process. Connect your phone to your computer in download mode for 3 minutes and LEAVE IT.

You can check Printers and Devices to see if your computer has recognised your phone. That's all I can say.

GOOD LUCK.

Default still problem with "UpTestEX.exe" r&d test tool

still no luck for me.
In download mode the phone appears to be properly recognised by my win7 pc.
waited more than 3 minutes before proceeding
all the same the flashing process exits with the "unsufficient battery level" message.

here the last lines of the "R&D test tool"log before it exits:


23:53:50 : *****Get ESN / IMEI / MEID Start*****
23:53:50 : ESN/IMEI/MEID : xxxxxxxxxxxxxxx
23:53:53 : Check Backup and Restore model
23:53:53 : Phone type Compare start
23:53:53 : *****Start _GetBatteryLevel*****
23:53:53 : ******************************
23:53:53 : Battery(1)
23:53:53 : You can't continue the process due to lack of battery power.\nRecharge the phone battery fully and retry.
23:53:56 : ~~~~~~~~~~~~~~~~~~~~
23:53:56 : !pUpgrade->StartProcessing ... PostMsg STEP_TYPE_ENV_ERROR
23:53:56 : Page_Error 부분입니다
23:53:56 : OnStepMsg STEP_TYPE_ENV_ERROR delete m_pLGCyonUpdate

(being quite sure there is enough charge in the battery)

very thankful for any hints

If you run it on windows 7, just right click on "UpTestEX.exe", choose "properties", choose "Compatibility", on tab "Compatibility mode" tick "Run this Program in compatibility mode for" and choose " Windows 7", after that, Apply and Ok.
So the issue is gone.
Goodluck.

If you are running Windows 7, right click on Up TestEX.exe in flash tool 1.0.5.4 folder, choose Properties, choose Compatibility, tick "Run this program in compatibility mode for" and choose "Windows 7", choose "Apply" and choose "OK".
After all, run "Up TestEX.exe" again, it doesn't ask about your battery.
Googluck.
