Where I can get .tot file for LG e615f? Phone is hardbricked, I tried to flash with kdz updater, but it stops with error "Phone not found".
Phone in QC-HSUSB download mode and don't switch on
Hi,
I have problems to get root access on my LG G2 (D802). I have a refurbished Vodafone device, which runs with the Lollipop version (5.0.2). The phone boots into the OS and works fine (as you can say with 5.0.2), but I want switch to CM13.
Unfortunately I can't access the download mode: I got the "Boot certification verify" error, which results in a DemiGod Crash Handler. I know, I should flash the phone with a stock version. But: I can't downgrade this phone - I tried every LG flash tool version.
Either the LGMobile Tool Suite says I already have the latest Firmware (trying to install a older version -.-), the process just stops because the phone is missing a functional download mode or the whole process just stops at 4% within the "S/W Upgrade is in process"-task and ends with a error message ("Upgrade stopped due to an error").
When doing the command "adb reboot recovery", the phone restarts. Sadly I only see the droid laying with an exclamation mark. I once accomplished (still don't knowing how) to get the options and I tried to install the kk_root.zip with the command "adb sideload", but there is another issue/error message: "E:failed to verify whole-file signature / E:signature verifcation failed"
Is there any other way to get around this mess and to install CM13?
Thanks in advance,

Hi,
I was attempting to flash my V20 (F800S model) with LGUP and Uppercut some days ago. The flashing got to 12% then stalled and eventually timed out and stopped completely after an hour or so. Tried it again, and got the same result.
I then disconnected the phone from the PC and force-shut it off. Since then, I instead get the error 0x81000302 in various flavours when I try to flash the phone.
If I use Uppercut combined with LGUP, I get the message "Error: 0x81000302, Please use latest DLL. LAF Protocol version is not match".
I've also tried using LGUP alone without Uppercut, instead using a DLL for the device. I extracted the file LGUPc.dll from the KDZ firmware I was trying to flash with, renamed it "LGUP_common.dll" and placed it in the LGUP\model\common folder. Then, as I again ran LGUP, I got the error "DLL for F800S10e is not installed properly. Please install a DLL package (*.msi) for the model."
I then installed a common MSI-packaged DLL I found online and tried again. That gave me the error "0x81000302, AtCmdTxRx Error".
Any ideas what to try next? Since that initial flash failure, the device has been booting straight into the firmware installation screen, and can no longer boot into Android. Really hope there is a solution that could bring it back to life!
Hello, my old LG G4c restarting itself and saying kernel crash demigod crash handler.
I try to flash stock rom via LGUP but now its fully bricked, when I try to enter in dload mode say: boot verification fail cause different hash

someone please help to bring back my lg g6 h870ds .(lock bootloader and cant fastboot ) all i can do is watch my lg phone on firmware update. if i restart it just always on same phase ( do not plug the usb connection until the process complete) . i already try to attempt to factory reset but it always stuck on system update i mention .
i tried LG UP and LG bridge but the same results , i downloaded the new virsion og LGUP .store .dev . lab and i have correct kdz and hash but it always says 0x20000 0x80000202 invalid response but the time i tried LG BRIDGE it fails and also changed the firmware of my LG G6 now i have to update to latest verion of LGUP and common dll . it runs ... but theirs new dialog says 0x7000 KDZ image corrupted but i double check it and it is a correct hash .. even in previous attempts it is always 0x2000 0x8000202 always on 11% to 12% of load until is stop . now in this new one 0x7000 thing its the same 11% to 13% of load until it fails . my suspicion about is maybe it just the same error but it just change its error message .
i just want to know if theirs a way to bypass its LGUP tool to clear the system cache of my phone because before i plug it and turn on debugging i got errors on LG firmware app it self it crash and stop always (my phone is alive in that time) the app that u used to update your lg phone without computer
