Usage: Enable Port Check Test in Hidden Menu(SVC Menu - Port Check Test). And turn on USB debugging,
Connect to PC, select Files Transfer. And you will see a COM port in device manager. (If not, you shoud install LG USB Driver)
Open this tool, select your COM port and click Connect, if your current MEID shows it means work fine.
Just enter a new MEID and click Write Hex MEID.
(Notice: The new one just type in DEC but not HEX, even it says "Write Hex MEID", I think this is a bug lol)

Thanks a lot. I dropped my v20 and it turned itself off. After powering it back on, I had no mobile network connection and my imei was reported as null. Running this program and connecting, disconnecting then restarting my handset was enough to fix the issue without even having to enter my imei in the box. Thanks a million.

Did u follow all the steps including changing the hosts file and changing the port to 9002 in the http server? AND A PEACE OF ADVICE USE LG FLASH TOOL TO FLASH SYSTEM ITS ALOT EASIER just download the system in bin/fls and follow the flashing tutorial.
sent from my lg o3d
a piece of advice:
don't ask alot ..go read.
yes, if you mean changing port 80 to 9002, I did, because couldn't find any other PORTs there.
Did also use flashtool, but with flash tool I got problem with OMAP4430 constantly connecting and disconnecting, not allowing it to browse and install driver for it (device manager)
/ another issue, if I ignore that OMAP4430 and just carry on step by step, change port to 41 for CDMA and open LGFlashTool.exe for , it just wont open, tried even on xp sp3, still nothing... it's 1.1 version.
^^^^^ scratch that, works now with 1.2 version
now have a question, If I have 170mb kdz for 21e, can I use it in FlashTool? Because to download BIN_LGP920AT-00-V21e-EUR-XXX-Apr-19-2012 , it's gonna be another hour, because where file was uploaded, download speed is so slow...........
I'm running on windows 7 x64
/// OMAP drivers still was bugged for me, eventho I tried lots of ways to fix it.
eventually, I used smart flash with 21e AP and CP and it flashes successfully
P.S. I do put back battery when flashing starts, otherwise ,it restarts at partition part!!!

For some systems there must be an injected EBL. The file specified for download does not contain an injected EBL.
Check that the file is correct for the target. This error can also occur on a normal boot time out, in which case just try again.

Okay i try LG PC Suite IV but some genius make the tool in Flash Player and doesn't works, the "LG PC Suite IV" animated image shows but doesn't disappear.
This phone is annoying, **** LG and locked bootloader
Do you installed the lg UP driver for SD810? You can find this in another forum(they called it only sd810 driver, but is not, this is a driver for LGUP and this is something different from normal drivers for our phone.
I don't know where, but I read you should use USB2 port to.
Yes i install SD810 drivers
Try to reinstall LGMobileDriver_WHQL_Ver_4.0.4.exe.
If you have installed LGUnitedMobileDriver_S4981MAN37AP22_ML_WHQL_Ver_3.8.1, uninstall it.

Worked for me, too, with my H811 T-mobile LG G4
Sent from my SM-G935T using XDA-Developers mobile app
Same was the problem with me but finally I figure out the solution...
Step 1..... Make a new folder by the name common in model folder.
Step 2....rename the file name Blabla.dll which you downloaded to LGUP_common.dll.
Step 3... Paste the dll file to common folder.
Thanks and be safe.
Hey guys i have the same issue with my LG G4, I been doing the instructions in the comments but nothing seems to work. I been using Flashtools14 and LG up. With lg flash tools it stops at 9%, and with LGup doesnt recognize my device shows as "UNKNOWN" does anybody still have this issue ?!

Nexus 5 Hard Brick

Hey yall,
So just a hour or two ago (as of this thread), I hard-bricked my Nexus 5 and can't get it to power on again. I tried disconnecting the battery and plugging it in again and didn't do the trick. I looked through guides on how to fix it but can't find any guide to fix it. I used Boarddiag but that doesn't recognize the phone (my pc can connect it, but says it's not recognized, prob driver issue) and other software but nothing works. Also when it's plugged in it makes a high pitch sound coming from the top of the phone.
This is really my gf's phone (not actually mine) and tried to put lineageos 18 on it (which i successfully did) and tried using a guide to resize the system partition to install gapps but that bricked the phone.
If anyone could help, that would be great. I want to give the phone back for her to use.

ok so i just figured out a guide to patch the boot partition but is still not booting up. Guide said there was a "fastboot mod" what does that mean? (also i was using a windows 7 vm since windows 10 wasnt detecting it properly)
I know it's been a few days but i figured out how to do it!
You have to: (these are the instructions)
-download the 16GB or 32GB patch file (which ever one is for your phone)
-extract the zip/rar/7z file (if you find one)
-Figure out which COM your phone is and it is in the COM Ports in device manager labeled "Qualcomm HS-USB QDLoader 9008" (or if you're using a vm for this method like vmware it can pop up and show which device you're connecting into the vm)
-On the com port, change it to the specified number and change the device to Nexus5
-highlight AP check, SDRAM test (and change that to level 1) and Restore Device
-press start and then your phone should boot up after everything is done! (you have to find your rom though, since it is not in the patch file)
My Nexus 5 was running at once and suddenly turned off while it was about 80% charged
What do you think is the problem? My phone may also be Hard Brick?

All required downloads are in the guide.
The Mi Flash Tool will lock the bootloader, by default, after flashing. If you don't want to do this, then change the option at the bottom of the tool before flashing (step 5)
If you wish to lock the bootloader, you must make sure the ROM region matches the phone, i.e. global ROM on a global phone.

However, I'm having a lot of trouble with the tool. It will not recognize my phone. I connect it, and the computer detects the phone. Then I click on "refresh" on the tool, and automatically the USB device is disconnected from the computer and the tool will not recognize it.
I have installed the Qualcomm and ADB drivers, rebooted and nothing changes.

Then, after hitting refresh (device still connected on Fastboot):

Sounds like a dodgy USB connection.
Try using the best USB cable you can find. If that doesn't work, try using a different computer. Fastboot and adb are very sensitive to the quality of the USB connection.
My old laptop will happily connect normally to my phone and I can transfer files with no issues, but from about a year ago I can no longer use adb and fastboot, with similar problems you are seeing. Using the same phone and cable I have no issues with my wife's laptop.
