We have no plans to support bootloader unlock in previously launched models or other variants of G4.

Cool, so after one of the major factors for me to choose the G4 was that bootloader unlocking was officially supported and would be coming to more devices, now it's not coming after all to us Canadian suckers. More reason to keep digging for an unofficial unlock...

 

[RenaKunisaki]

Oh, if people are planning to unlock, it'd be awesome if they made a full dump of the eMMC before and after, so we can compare and see what all happens when you do it.

No issues on h815 eu

I read the LG boot unlock affects streaming services. Can you tell me if it's still possible to stream music from the google play music app, and also YouTube ? Cheers.

G4 runs like stock version (if you don't install mod) in apps

Any news about progress for full root(with recovery) for our G4s?
Since the low effort root is out it's very silent

How can I figure out if my phone is EU or not?

Still no unlock for the US Giveaway version of the H815. Surprised since they don't give any support (updates and the like) for this phone that they are not allowing for it to be unlocked at the moment.

"Unfortunately, your device (Singapore) does not support unlocking"

I purchased an "unlocked" G4 (LGH815) from Amazon. After going through the painful unlocking procedure, the process failed at the last step, emailing the unlock bin from LG, with the message "Unfortunately, your device (Singapore(ARROW(SINGAPORE))) does not support unlocking the bootloader.

Any advice on how I can root this device, please? Thanks.

Unlocked means not network/carrier locked. it doesn't mean bootloader unlocked.

You can root using the low effort root in the original dev forum.

Thanks, I'll give it a try once I get my courage up.

Edit: having problems with TWRP 2.8.7.0 (overwrited by system recovery on each reboot) , installed TWRP 2.8.6.1 and now seems to be OK .

You will lose root and TWRP.
The bootloader stays unlocked.

That's good news then!
I mean at least I won't have to go into unlocking process and wipe all internal user data
So I just have to pick the no data wipe option in KDZ flashing to update from 10e to 10h (using kdz 10h file), then use the OP tutorial starting from the point after the G4 has the unlocked bootloader right?

That's it, precisely.
Use the "Normal" flash within LG Flash Tool 2014. Your app data won't be deleted.
Once flashed, install TWRP and Root.

Hi, i may well be posting in the wrong bit here, so apologies in advance...and please forgive my lack of lnowledge, still learning lol-

If i may pose a question regarding inlocking the bootloader via lg official meathod - i would like to know, if i use titanium backup to store system and app data, could i unlock the bootloader, install twrp or cwm recovery and then restore my stuff via titanium?

I am using lg g4 815 v10c - rooted

Thank you all in advance!

For the people having this issue...

ah, thought they were supposed to show on the phone screen.

not sure what you mean by shutting the cmd window? I just get stuck on that "waiting for device" message in cmd, at which point I unplugged the phone, did a battery pull and tried again. I've tried about 5 times now, I double checked everything, have all the drivers installed etc.

Oh, and I do have the h815 EU version of the G4. I'll keep digging.

this helped me, hope it helps some people. Sadly my phone was made in taiwan which i find stupid from lg since it is still the h815

I think all the G4s are made in Taiwan. It's just which market they're sold in that matters.
