I bought this phone and I cant restore it to stock firmware with flashtool cuz computer thinks its a different model than the dll and tot files, Ive tried with the dll file that supposes to ignore de model number but i get crossedl error.
I can push files in adb but it seems like twrp wont flash anything properly, for example If i flash a rom the process takes like 4 seconds but when I reboot the phone it goes back to twrp, Ive tried flashing a newer version of twrp but its the same thing
Is there anyway I can force my phone to boot into fastboot? any help would be appreciated
I fixed it pushing the original built.prop from another g2 using adb commands and then i used flashtool.
Hi,
I am stuck with a LG G3 US990 on download mode. Following is the history:
1. Restored a LG G3 LS990 Nandroid Backup to device.
2. Flashed Cloudy 1.3 in hopes of getting a sim unlock(sim unlock failed - network was still grayed out)
3. Tried to restore phone back to LS990ZV4 stock using fastboot.
4. Accidentally flashed laf and stock recovery.
5. Stock recovery was accessible for a while and the phone showed "Security Error" when trying to do a normal boot.
6. Above later changed to Download Mode. Now, the phone goes to Download Mode if a normal boot is performed. When tried to get to recovery, it shows "Recovery Mode" but still goes to Download Mode.
When I try to restore phone to LS990ZV4 stock using Flash Tool 1.8, I get an Error: Partition Table change 00000064. When I try to flash it back to US99010a stock using LG Flash Tools 2014(I have to do this as US99010a only has kdz), the phone is never detected. I have tried multiple reboots of my PC, changed com ports and everything possible else than using another PC.
I also tried to extract dll and .dz from the kdz to use on Flash Tool 1.8 but that failed with error: Failed in Previous Load ().
On LG Flash Tool 1.8, the phone is detected and progress goes up to 6% before partition table... error is displayed. Phone Model shows as LGLS990 and IMEI,PID info is unknown.
Any help on this would be greatly appreciated and I would recommend anyone trying to get a sim unlock on US990 should definitely refrain at this moment as I have apparently lost a device in this pursuit.
Thanks to @Abu Siona for all his help so far!

try this:
note: that what you are trying to achieve is take the phone into fastboot mode so you can then fastboot flash us990 partition data (laf.bin or laf.img from us990)
plug in the phone thats in download mode
download and extract the attached, change into the extracted folder.
start command prompt in that folder ie
execute ports.bat ( this shows your lg diag amd mdm ports) your diag port i want to assume is com41 (flashtool port)
when in download mode, check your flashtool com port (want to assume is com 41) if not replace appropriately with the right download mode comport. default here is com41
so copy and send this as below (be sure you have the right com port specified):
Send_Command.exe \\.\COM41
this takes you to su (root) and you should have the # sign
then delete the laf file thats causing all the stress by sending the command below:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf
with the right port selected after this command it should return #
then reboot phone battery out and in, then power , if all went well you should be back in fastboot mode, then grab the us990 Z4 partition and fastboot flash into phone. you should be good.

Hey,
Thanks a lot for this helpful post! Device now boots in to fastboot mode and though I am able to write most of the files, I am not able to write following files: BackupGPT, rct, PrimaryGPT . The error which I get is "remoteartition table does not exist"
I tried flashing TWRP recovery but instead of going in to recovery the phone goes in to download mode.
Thanks!

You ll need to fastboot flash laf.bin if you open / edit the flash.bat laf.bin was not included I think .. just get back to fastboot mode and fastboot flash laf.bin like:
fastboot flash laf laf.bin
reboot and phone should boot normally and all modes should work.
Thanks

Hey,
Thanks much for your reply. I followed your instructions and was able to boot successfully in to fastboot mode.
I proceeded to flash the partitions including laf.bin but the phone still goes in to download mode. I tried flashing partitions of both US990 and LS990 with same results.
Also, I was not able to flash following partitions from either of US990 or LS990:
rct.bin - Error in fastboot while flashing- remote: size too large
PrimaryGPT.bin - Error in fastboot while flashing- remote: Partition table doesn't exists
BackupGPT.bin - Error in fastboot while flashing- remote: Partition table doesn't exists
From my understanding the Partition Table is broken or actually does not exist at all and hence I can not write the OS, I might be incorrect though. I need to figure out how to re-build partition table or broken partition on LG G3.
Any help would be greatly appreciated.

Sometimes the solution is simple and the brain just won't think in the right direction. I was finally able to restore my US990 back to US990(it got converted in to LS990). The solution is to flash TWRP in fastboot and restore the nandroid backup. MAKE SURE YOU HAVE A NANDROID BACKUP before you get in to the conversion business.
Thanks a ton to @essojay

I can only confirm once I'm able to achieve the unlock. I have now flashed Cloudy 1.3 on the phone again and it's a LS990 now. The Bluetooth and MAC addresses are unavailable and there is no network. I'm thinking what to do next.

US990 Bands: LTE B1/B3/B17/B18/B26/B41, WCDMA B1/B2/B5, GSM 900/1800/1900, CDMA BC0/BC6
@Abu Siona
I cannot register on Rogers in Canada apparently because it operates on 850but the phone reads my sim card and also is displaying the phone number.
My device is converted to a LG G3 LS990 and is running Cloudy G3 1.2 . I used shortcut master lite to change the bands. No luck with GSM, can't confirm CDMA functionality. Will be back down south in a few weeks and will then test if this phone works with T-Mobil or any other operator in States.
No download no fastboot
I'm getting emojis and a black screen.. no download mode and no fastboot.. Any ideas would be greatly appreciated, possibly a command to write the new laf.bin , img or boot/recovery img files?
"#dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/laf

Please help mE my Phone Lg g3 Stuck In Download Moad i Trying To flash But Laf Read Gpt ProbLem Faced Help Me Please How To solve this Problem
Hi, new here.
I do believe you guys aren't too keen on US Cellular. But I have all of the files I need. It's more of an overall sort of question.
So here's my situation:
I was being stupid and messed with the permissions on my phone, not knowing what I was doing(trying to get titanium backup to move apps to the sd card). Well, it messed up my phone. Anyways, I tried a few things to fix it and then it got stuck in a bootloop.
I am currently able to get on TWRP and fastboot. I need to get the LG Flash Tool to see my device to flash the stock KDZ but it won't see my phone without Download mode. I wanted to put my laf.img file onto my phone through fastboot to get Download mode back. My phone will show up on my computer, but when I try any ADB or Fastboot commands, it shows no devices.
Is there a way to flash my KDZ without restoring my Download mode?
Is there a way to put the laf.img onto my phone since my computer cannot see my device(through asb/fastboot)?
Is it possible to convert the laf.img into a zip and flash it through TWRP and get my download mode back?
Thanks for the help, and sorry for the long post.
UPDATE I screwed myself a little on this one. I no longer have TWRP, it goes straight to fastboot. Any Help Please?
What model do you have?

It is possible to make an update.zip to flash the laf.img to the laf partition but I don't know how. Also you can use fastboot to flash the laf.img just boot to fastboot plug your phone into your computer and run fastboot flash laf.img laf
That should do the trick. Or you could flash a rom to fix the permissions. Any US cellular compatible rom should work.
Also TWRP has a file manager that might be able to fix the permissions if you remember what they were.
Hope that this helps.
Hey guys, I think I may have permanently bricked my device :/ As it is a H810 there is no recovery available so I can only enter download-mode and fast-boot mode. Basically I accidentally flashed the wrong files
dd if=/sdcard/modemst1.img of=/dev/zero of=/dev/block/mmcblk0p24
dd if=/sdcard/modemst2.img of=/dev/zero of=/dev/block/mmcblk0p25
dd if=/sdcard/modemst3.img of=/dev/zero of=/dev/block/mmcblk0p26
as I transferred the incorrect backed-up files from my computer (I ended up flashing my friends H815 backed up files by mistake). This meant that the phone was unable to boot and is now stuck in a boot loop. I have tried flashing the partitions using fastboot flash mmcblk0p24 modemstl1.img without success and in download mode the device is not recognised so I cannot perform an adb push/pull command.
Thankfully I do have the correct img files to flash back on my computer but I cannot figure out how to actually transfer them to the device. A side note- LGUP does work successfully to flash a stock TOT file to Lolipop so if that is able to copy the new ROM to the device and flash the system partition there might be a way to transfer the files over. The only problem I can see is there really is no way to unlock the bootloader and as the files are not 'stock' this may not be possible.
If anyone has any ideas that would be greatly appreciated. Cheers.
But if LGUP is working for you, why dont you use the option to "upgrade" the phone to the version of the ROM you were using ?
My lg g4 h810 is stuck in fastboot mode not recovery mode not downloading please any one have any idea
i got some friends in another lg thread that have unlockable bootloaders but no twrp one erased his system partition and wondering
if some one could tell me the commands to do a device back up from fastboot and be able to restore it on his?

So no TWRP even not unofficially??
If you have TWRP it's easy...
fastboot boot twrp.img
But without TWRP... is the download mode working? You could use the lglaf shell (in FWUL) and then backup with that terminal.
I don't think that fastboot will let you do backups though.. maybe I'm wrong but I think your best option is to backup by download mode and then reflash an original firmware. It's still fun how to restore those backups then..
Depending on the device it could be possible to even use dd in download mode to restore just system.. But most devices prevent this afaik..

TheMadScientist420, Hello again ... steadfasterX is correct about using download mode. But if they cannot boot in android because of wiping the system partition, they may have to flash a stock KDZ with LGUP-NEW and start again. Add: Chances are that any model with an unlockable bootloader will NOT have the ability to use fastboot commands - that is the case with the H812, for example.
For future reference in the event as a precaution, refer to the following link in the 3rd "Quote" down: Backup System to Internal Storage (Commands for all variants): Doesn't matter if it's rooted, (Add provided they have a copy of the stock KDZ to install first with LGUP-NEW).
https://forum.xda-developers.com/showpost.php?p=62028523&postcount=2 for the appropriate command.
Use the Send_Command.exe \\.\COMx within the Root LG folder when in download mode (with the appropriate port ascertained for the 'x'), from the Root ANY LG G4 Variant 100% Success Directives | Root Injection | Less Bricks[/I] at https://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586 to access and send the above command for the appropriate model.
Tell them to backup User and System apps with Titanium backup first - they can restore pretty well everything from there if needed.
