[UNLOCK][UNOFFICIAL][G4] Unlock ANY* LG G4 device with UsU

[doop]

Since my H810 isn't my daily driver any more and after following this thread for a looong time I decided to take the plung and unlock. Salt said "Some parts of UsU couldn't be flashed!" and continued but when that was done I was unable to boot into fastboot mode. From there things mostly failed. I do have a full salt backup from a few days ago. Right now the phone won't boot into either download or fastboot mode. Happy be be a guinea pig. Logs below:

Have you been usuing the post USU method of entering fastboot? ie:

Fastboot

After you unlocked your device with this method you will also have an unlocked fastboot mode which can be accessed by a key combo:

take out the battery
unplug the usb cable from the PC (not from the device)
Insert the battery again
wait 2 sec
press volume DOWN and while keeping it pressed: plug the USB cable to the PC
keep volume DOWN pressed until you see the fastboot screen

Yes. I made sure to carefully read and follow all the instructions. I might try the SD card trick posted here

Ok the first thing: all went well on yours but your Ubuntu version do not have the fastboot command available. One more reason why I recommend FWUL which has all needed onboard..

The hash verify failed due to an issue in the way SALT verifies the hashes. In real the flashing was successful but the fastboot reflash afterwards failed as you have no fastboot on your linux. Maybe that screwed it up somehow..

So what's happening now when you connect the device to your Linux?

Type in a terminal:
lsusb

and paste the output here..


And if you see nothing do the same but take out the battery.

Ah, good call on the missing fastboot. I had used an older version of FWUL on a USB drive but persistent mode kept having issues of not staying persistent. So I just went to a full blown installation of Ubuntu and installed SALT manually. lsusb doesn't show any recognized device in any state or any key combo I've tried. With the battery out I get a icon of a red question mark flashing around the outline of a battery.

I flashed H811 Lineage 14.1 from SteadfasterX's build server for my VS986 and I'm facing a black screen on boot and incredibly long boot times where Lineage boots into safety mode. I flashed the N modem and everything. Any ideas on why this is happening?

 

[steadfasterX]

Have to sleep now.. Cu tomorrow

I recommend all to wait for SALT V3.9 before flashing.

I installed RR 7.1.2 (H811 ver) on my h812 but there are a few issues popping up, like sound not working, youtube videos barely able to play, and sensors not working. Is anyone else experiencing these issues?

I decided to say screw it and go back to stock rom (h81220z), but problems mentioned above still exist even after going back. Please help, i do not want to live with this! :crying: :crying: :crying:

Okay so the way I fixed this was by once again doing the modem flash in TWRP as stated in FAQ. I don't know if the N modem is needed at all on VS986 or not even if you're using a N rom unless the modem flash doesn't touch whatever the N modem flash did.

Something strange happened after booting up my H12. Since I haven't used the phone for quite awhile because it's not my daily driver, once I restarted the phone and went online some lg apps were updated and somehow twrp recovery was reset to the default lg one. I have to flash twrp back up again and disable auto update of the lg apps and software. Is it possible for lg to send update to our phone and somehow brick it because it's unlocked unofficially? I mean if auto update on software and apps are on? I haven't tried flashing a custom rom yet as the 3rd poster above me is having some issues after flashing a custom rom and continues even after he went back to stock.

Thanks to steadfasterX for his hard work.

edit: Flashed magisk with no issue.

This issue is not directly related to this thread. It has been well covered in the H812 [Canadian Guide] thread. BUT, that said, it could be run into when re-flashing your stock rom with SALT and could present on other models as well when flashing their stock roms, as re-flashing etc. seems to unfreeze the relevant apps.

In a file explorer check if you have 'App Updates': /system/priv-app/LGApplicationManager/LGApplicationManager.apk
If you have it, FREEZE it.

Important: Make sure you FREEZE 'Software Update': /system/priv-app/LGDMSClient/LGDMSClient.apk as well, otherwise you risk your LG carrier trying to upgrade your firmware which will likely lead to a brick by doing this way.

 

[mertklic]

I will try it on my H815TR
Hope it works!
thanks for the topic sir! :angel:

Edit: sorry for being an idiot but im new to these things Does this rom pass your limitations? Is it KDZ/TOT?

Sorry and thank you again!

Salt for Windows

Is there any chance that you could port salt to windows? My pc isn't able to handle virtualbox very well and I don't want to mess with the BIOS settings to use a live usb.

Hate to admit it but I believe I broke something.
Good news: fastboot and twrp both work.
Bad news: none of the roms seem to work for me.

1 wipe dalvik, cache, system and data
2. Flash aoscp 5.3, gapps, magisk
3. Flash baseband package
Reboot and after the LG logo with warning a black screen with the text "invalid ram console!!!" greets me.

I assume I made a mistake along the way but tried all combinations and can't seem to figure it out. With modem, without modem, with gapps or without you name it. Any help would be greatly appreciated

Which model do you have?

 

[keeponjammin]

Which model do you have?

The h815p

 

[hey_joe]

The h815p

Have you tried flashing just the rom and boot up?

Did you flash the N modem?

This is just for app updates right?? Tell me how does updating apps lead to brick????

I see you still do not how to read thoroughly ... the brick refers to and was only referenced with respect to the Software Update app. If you need an explanation as to the 'why', I suggest, as SteadfasterX has suggested to you already, that you do not unlock or flash a rom ...
