Also, Android security updates. Firmware blobs might be a different story. Although some of the problems with firmware blobs might be rectified with HALs (Hardware Abstraction Layers), if I correctly understand how things work.

What do you call firmware blobs ? Are some features of the phone not supported ? I know IR blaster was not working with LineAge but who cares...
For camera what will happen ? I know that there are some GCam portsq but will it access all mechanical features of the camera like optical AND mechanical stabilisation ?

Firmware blobs are the closed source drivers for the hardware. They are provided by LG. They haven't been updated for quite some time. This is why the G5 still uses a very old linux kernel.

GPS was always bad and was broken on stock already like fingerprint sensor was.

Are the results goods ? I bought G5 cause it was at this time one of the best cameras abd the manual mode allows to do awesome photos.
For GPS, it works fine since I changed the screen. Only problem is that my new screen has a broken phone speaker and broken proximity sensor x)

After spending a lot of hours looking and buying me a nice Smartphone (LG G5) to use with lineageos... Here is the end of this excurion: website closed, no unlock possible. :confused: Shame on You, LG Electronics!
I will never more buy any device from LG and I will never recommend one. But I will tell everybody how LG dealt with us. Is there any online-petition to sign?
This was so predictable: unlock by an website is a bad way, because it needs manpower. Companies that go this way are not selling products to us. They are lending it to us. We are not free to use our device in the way we like.
Never buy a product (computer/smartphone/tablet) which depends in support of the manufactorer. This kind of dependency is only useful to satisfy the manufacturers control mania.

But, what should one expect? The good old LG G5 is still a worthy competitor, concerning its modular build and its maintainability. LG didn't liked to stay on this way, as they proved with the successor G6. No difference to the competitors: They like to produce "disposable-like" high-tech products with a short period of use.... and people obviously like to get fooled to buy this stuff with/by advertising (clued smartphones/tablets, which are hard to maintain, concave displays, which are difficult to protect but prone to scratches an reflections).
Sad world. No future. :cry:

I have found unlocked H850 motherboards on aliexpress. I'm suspicious but the seller is certain they are bootloader and carrier unlocked. Does anyone know if this sounds legit? I might purchase one to find out. I have multiple H830 and a RS988 LG G5's that are fully unlocked and was thinking of just swapping in the motherboard to test it out. Should this work fine?

Hello. I kindly please for help.
I own a perfectly working LG G5 (H850). The only problem I see approaching is that 3G will be turned off in next time, and this will make my phone possibly useless. My phone uses the "latest" android, 8.0.0 (the last version it received).

As far as I found out, the phone uses 3G for voice and 4G for data. Calling LG, I was told that this is preset somewhere in the phone and I cannot access and change that.

Is there really no way to enable 4G mode for voice and data?

I also thought about installing a custom ROM, but this would require to unlock the bootloader. Clicking in the link above, I only got the iformation that this "official way" is terminated since ...

Can somebody guide me, please? I really do not want to brick my phone.

Doesn't the G5 use 2G for calls if VoLTE isn't available? That's at least the way it works in my Country (Germany) as 3G has been shut down a while ago.

By the way - I have a fully working, unlocked and rooted EU G5 H850 with Lineage OS 18.1 to offer. Worldwide shipping is possible. Unlock.bin file is also available.

    The European H850 can now be officially unlocked through LG's developer unlock program page.
    Yes, only the European version. Your H850 is from the Middle East? Won't work. You have an AT&T G5? That's not an H850, move along.

    LG Developer Unlock Site Here
    ​

    Prerequisites:
    1. European LG G5 H850
    2. Computer w/ADB & Fastboot. ADB/Fastboot for Windows here. ADB/Fastboot for Linux/OS X here.
    3. Basic knowledge of ADB, Fastboot and Windows command prompt or Linux/OS X terminal.
    4. Device IMEI. This 15-digit code can be found on your box, the back of the phone or by dialing *#06#
    5. LG developer account (free, click here then click sign in at the top of the page to make an account.)


    Directions:
    LG's official bootloader unlock directions can be found in the big link at the top of the page..
    but I've still rewritten the steps out below while adding some for root and TWRP.

    1. Enable USB-Debugging on your phone. USB-Debugging is required for the commands “adb” and “fastboot” to work. To enable USB-Debugging, go to Settings >> About phone >> Software info and tap Build number 7 times. Return to the previous screen, select Developer options and enable USB-Debugging.

    2. Enable OEM unlock on your phone. Activating the "Enable OEM unlock" is necessary for the bootloader unlock. To enable OEM unlock, go to Settings >> Developer options and check Enable OEM unlock.

    3. Open CommandPrompt or Terminal and enter the following ADB command to reboot into the bootloader:
    Code: 
    adb reboot bootloader
    If ADB is not detecting your device try switching your phone's USB mode from Charging to MTP or PTP.

    4. Once in the bootloader, use the following fastboot command to obtain Device ID:
    Code: 
    fastboot oem device-id
    Fastboot command will return a string. This is the Device ID which is needed to generate your unique unlock key.
    Example :
    Code: 
    $ fastboot oem device-id
(bootloader)-----------------------------------------------------------------
(bootloader) Device-ID
(bootloader) CD58B679A38D6B613ED518F37A05E013
(bootloader) F93190BD558261DBBC5584E8EF8789B1
(bootloader)-----------------------------------------------------------------

    To generate your unlock key, you will need to paste together the 2 lines of output into one continuous string without "(bootloader)" or white spaces. In the example above, the Device ID would be:

    CD58B679A38D6B613ED518F37A05E013F93190BD558261DBBC5584E8EF8789B1    ​

    5. Copy Device ID and IMEI into the LG developers unlock site and hit the confirm button. In a few moments the unlock.bin will be emailed to you. Download unlock.bin to computer.

    6. While the phone is still in fastboot enter the following command to unlock the bootloader:
    This will unlock your phone AND factory reset your device wiping all data!
    Code: 
    fastboot flash unlock unlock.bin

    7. You can now reboot the phone and boot into your unlocked device! Enter:
    Code: 
    fastboot reboot

    8. Want root or TWRP? Before moving forward I suggest getting a microSD card and putting the SuperSu 2.65 zip on there. Do not set the external SD up as adoptive storage. Download this TWRP image too.

    Reboot back into the bootloader (you'll have to first re-enable USB debugging):
    Code: 
    adb reboot bootloader

    9. Flash TWRP:
    Code: 
    fastboot flash recovery twrp-3.0.2-0-h850.img

    For TWRP to "stick" you must first boot directly into TWRP and not back into Android, until after flashing the SuperSU zip.
    After flashing TWRP unplug the USB cable and pull the battery. Plug battery back in then boot into recovery which should hopefully load TWRP.
    To boot into recovery:
    a. Using 2 hands.. use one hand/finger to press/hold volume down.. and use the other hand for the power button. Press n hold both buttons.
    b. As soon as you see the LG logo on the screen.. let go of the power button then quickly press it again (never letting go of volume down).
    c. Keep holding until you see the Factory Reset screen. Click thru the factory reset screens.. Yes.. Yes...

    10. You will not be able to decrypt your internal data while in TWRP (unless performing a full /data wipe in TWRP and you will lose encryption!) but you can manually mount your external SD card to view the SuperSu zip. Feel free to back up first.. but otherwise.. time to install SuperSu. Click the Install button and navigate to the external_sd, select the SuperSu zip then swipe to install. Now you're rooted and TWRP'd! Reboot into system...

    Have fun and be careful.


    FAQ:
    Q: I have an H850Q from Israel.. can I unlock the bootloader?
    A: No, this official unlock program is ONLY for the H850 model for countries in Europe just like LG did for the LG G4.
    But... for about a 10 day span last year G4 devices from SE Asia worked with the official site and users received unlock.bin files. :good:

    Q: Will more devices be added?
    A: While there is no "official" word.. most likely no. Unless another mistake happens where another region's H850's are allowed for a week.
    Other than then EU H850 and possibly the T-Mobile H830... no other variants have a shot at being bootloader unlocked officially.

    Q: I can't get my phone to show up with ADB or Fastboot, watdo?
    A: Make sure USB debugging is enabled and try changing the phones USB modes.. from maybe charging to MTP.. or MTP to PTP.
    Make sure drivers are installed if using Windows. Learn2Computer.

    Q: Where can I get drivers and things?
    A: A good start is my G5 Info thread found here. Google and this very website are good places to search as well.

    Q: What happens to warranty if I unlock or root?
    A: YMMV I suppose. The official LG site claims that warranty is void if damage is caused by the unlock. Not sure how they could prove such things. I thought there was some EU law that gave everyone warranty coverage even if unlocking the phone. Not sure if that is enforced or even still valid at this time... maybe someone knows for sure?

    Q: Can I re-lock the bootloader?
    LG does not support re-locking the bootloader... so once unlocked you remain unlocked.
    Thanks to @Loggsie for the heads up... the previous statement above is confirmed not true.
    It IS possible to re-lock the bootloader with the the command: fastboot oem lock
    I wrote a bit more about it in this post HERE... and in the post under that.. @wolfgart shows off some examples.
    DO NOT re-lock the bootloader if you have a modified boot/system img... restore them to stock first or you will not be able to boot into android after the lock and need to flash a KDZ in download mode.

    Q: So many words... yudodat?
    A: Here is a video on how to unlock the G4... up until the 6minute mark it is step-by-step 100% the same as G5. Only slight difference is when you get to the TWRP/root steps. https://www.youtube.com/watch?v=O64GfQORCaE

    Thanks to a fellow G5 user I have been notified that it is indeed possible to re-lock your bootloader on the H850 variants.
    All credit goes to @Loggsie for this great find... it was not mine. Be sure to thank them :good:

    before re-locking I would suggest flashing the stock boot and system img otherwise you may enable dm-verity as well as boot.img signature checking and you won't be able to boot due to modified partitions. And since you can't boot directly into fasboot to easily unlock again you'd be screwed until you flash a KDZ in download mode.

    again... do not re-lock the bootloader unless you have already flashed back your stock boot and system imgs. Or to be safe.. just flash a stock KDZ in download mode. then you could boot into android.. confirm OEM Unlock is enabled in developer settings... reboot into bootloader.. then finally re-lock the bootloader.

    to relock the bootloader:
    fastboot oem lock

    bootloader should now be locked... and the yellow warning sign when booting should also be gone.

    I have no idea if or how this will change warranty status. I suppose we'll all see how it plays out by the experience of others on here.

    Looks like the TWRP hang may be due to sdcard format.

    If using EXT4 or ExFAT try FAT16/32... (let the phone format your card while it's booted in Android).

    That should at least get you into the TWRP menu now.
    I suppose you could avoid using an sdcard to hold SuperSu as well... alternative would be to boot into TWRP while not using any sdcard then using 'adb push' to push the SuperSu zip from your computer to your phone...

    Code: 
    adb push UPDATE-SuperSU-v2.65-20151226141550.zip /tmp/

    Then hit the Install button.. navigate to the "tmp" directory and install SuperSu.

    TWRP issue will be sorted soon I'm sure.. since it's most likely just a formatting issue... possibly ExFAT/EXT4 not yet supported.

    For stock recovery someone with H850 would need to fastboot boot twrp.img (not fastboot flash recovery twrp.img) and then backup recovery and share it with everyone. Or you would need to wait for root (without bootloader unlock.. most likely a temp root) and then backup stock recovery.

    It looks like a few of you have been denied an unlock from LG... and they seem to be carrier variants of the H850. So.. it is possible that SOME H850 carrier models are not yet "eligible" for official LG bootloader unlock and only EU carrier-free H850 variants can unlock. This is how LG did it last year with the G4. At first, only carrier-free variants but then a month or two later they opened it up to EU carrier variants.

    the H831 most likely does not have a visible fastboot menu for unlocking. Only the H850 variant and possibly H830 will be officially supported. It's possible that if a temp root is available you could wipe laf or recovery partition and boot into a "fastboot fallback menu" but this is not the proper fastboot and all fastboot commands will be broken. I suggest no one attempts this unless you know what you're doing... and if that were the case you wouldn't be listening to this anyway.

    As mentioned above... toggling OEM -Unlock in development settings does NOT void warranty. Requesting an unlock.bin from LG does NOT void warranty either. Only possible way to void warranty would be to see you device in person with the unlock flag on your phone set.
