LG G3 bricked - Android Q&A, Help & Troubleshooting

I have LG G3 Sprint LS990. I changes it's model number and it was working perfectly. But suddenly I flash Galaxy S5 ROM via TWRP recovery and the phone got HARD BRICK. I tried to flash via LG Flash Tool with TOT and DLL file but FLASH TOOL says at 9% Check your model number ( I have model number LG G5 in G3 SPRINT BUT I HAVE DLL AND FIRMWAER OF MODEL L990) ( i HAVE ALREADY EDIT DLL FILE BUT NO LUCK) Still flash tool says check model number. So now what can I do to FIX LG G3 LS990. I think OCTOPUS BOX will fix this. And what you say about FIX it. The phone can only go to DOWNLOAD MODE.

buy a brand new motherboard and put back on

Change the device name in build.prop to Apple (case sensitive) and u can even flash iOS on it. It just works

Sprint LS990 Model Information Check Failed

I attempted to root my Sprint LG G3 and bricked it. I am attempting to restore it with the following.
LG Flashtool V.1.8.6.527
LGLS990_20140704_LGFLASHv160.dll
LS990ZV4_04.51101.tot
I have tried to restore but it keeps telling me the Model Information Check Failed.
I have seen a post about a Verizion phone with the same problem and was told to swap out the dll file with a differant version and that fixed his problem, I am unable to find an allternitive dll for my LG G3 any help would be appreciated.
Hi
I would advise that you check the model number of your phone on the motherboard.
My phone had D855 written all over it, but when I opened it up, the motherboard was LS990!
It was a refurbished phone
Have you figured out a solution to this? I also have a Sprint G3, a LS990, and am having the same issue when trying to flash a .tot file with LG FlashTool.

F700l model to F700k

Hello everyone, I'm residing in Korea by the moment... my carrier is olleh (KT)... I used to have an LG G pro 2 from the carrier so had no problem at all. recently I switched to a new G5. the problem now it's the model is F700L (from other carrier) and there are some benefits I get with my carrier (KT) that I can't when the phone doesn't match the same carrier ...
I've been reading and researching about changing the rom to the one from the other carrier, and LGUP throws error when saying: Error F700L > F700K ... I know there won't be any problem doing this because the hardware is the same. And as far as I know there's no possible way to root the phone and unlock the bootloader or install a custom one for later on install the other rom from there... :silly::crying::crying: .... so....
after so many days trying got disappointed and annoyed... gotta ask... is there any other way to flash without confirmation? (with Odin or other?... FlashTools doesn't get to communicate with the device in download mode... and LG Flash.. requires a DLL and can't find it anywhere...) ... or getting inside the phone using ssh (i'm linux user) or other with the help of the adb ... and get to edit the model just to change the freaking L by a K??
The other possible way could be editing the actual KDZ to match the info... I've tried WinHex but LGUP says: Invalid KDZ after the edition.... some other way?
will appreciate any idea... thanks!

My lg g8x is g850EWM(DEU) version but my second sim imei is missing and my phone model number shows g850UM. Help!

I got my phone from aliexpress and i updated it using lg bridge. My model number changed but then i downloaded the original g850EWM(DEU) from lg rom website, extracted it and flashed it's abl_a.bin file and the model number shows correctly. Now i lost safetynet and i was trying to fix it so, from a guild on the g8x telegram group I erased from Qfil, modem_a , modem_b, boot_a, boot_b, and then flashed the g850EWM(DEU) through lgup. Now my phone reads the model as g850UM. Any help!
