Unknown developer but please this phone will never be unlocked you'll never be readable right? Thanks in advance take care!!!


The bootloader can be unlocked supposedly but you cannot flash anything because lg decided to remove any fastboot commands and this to even further sell less units because there will never be any development for their devices

There is a way to run code to boot a recovery to root. I only know what is needed to do the root option.

You need an LG device with a boot loader built before June 2020. That covers a load of LG devices.

To gain the ability of rooting, you need to drain the battery beyond zero (android 0v) requires rebooting many times after device shuts down for zero volts on the battery. Once that is done, you will need to connect to a pc through usb. The boot will bypass the standard boot routine due to under voltage of the battery. You will need to write code within an image file to push to the phone. The image with code will then push your recovery to boot from sdcard. Thus you will need a recovery saved to sdcard prior.

There is a more detailed write up, in the June LG Android Security PSA from a developer.

Once an LG phone has a patched bootloader built after June 2020, this back door method to bypass bootloader security for root and other things, will not function.

I think I can search and find that info. But it is not detailed enough for most developers to make it work, without more work involved and testing.

Can I get a link to the write up?

Ok, it's been few months and development on this phone has been dead. Seems like people have given up. But I'm really desperate to get this phone rooted. I even created a thread here to setup a bounty!
At this point, I'm willing to put my phone on the line. A little bit about myself, I'm a software engineer but never worked on phones. I'll start reading about rooting and bootloaders and try to see if I could be of any help.
This really sucks. I'm on t-mobile. Is anyone else in the same situation as me?

EU here, Software dev as well that is deeply engaged with Linux (running Arch on the private Gaming rig levels). Once my phone arrives I'll give it a shot, but since I have the EU version (that can be unlocked officially now) I might not be able to help you out too well.
But I'm very set on getting Lineage to work on this thing, one way or another.

I have been trying on my end too in my spare time. Any help is much appreciated. Hope you enjoy your new v60

Even if you manage to unlock the bootloader (hope so cause I love lg) how do you plan on rooting since lg decided to remove all fastboot commands to flash any su binaries?

It's difficult given the RSA certs that will hard brick during cross flash attempts such as trying to flash protected partitions such as abl. I killed many v30 being a guinea pig.

I also don't understand why lg refused to release the firehouse files to use with qc mode. My guess is $$$

I don't know. But I'll risk it anyway. It's a do or die situation for me. I'm open to suggestions to try on my tmo v60 which is a guinea pig now. I have a rooted tmo v20 which I can use as a backup.
I have never done anything on my own so far and always followed the guides. So I'm open to ideas and suggestions

If you do kill your device, just call tmobile and tell them you were doing a system update and it didn't turn back on and they'll send you a replacement. (No physical damage on the old one or you'll get charged)

Good luck

is there a way to switch partition slot ?

my LG G8 and V60 updated to android 11 and i hate it.

is there a way to switch slots to boot in my old android 10 partition ?

a way to roll back to android 10 on LG v60 Tmobile?
 
It doesn't necessarily mean the bootloader is unlockable. If so it wont be unlocked using commands in fastboot which is non existant to builds since the launch of the phone. Getting fastboot capabilities could be possible also yes. This is a job for LAF / EDL and hacking deep into this phone to see. If you'll take the V30 ROOT for example it was another EDL and LAF explored job. Before XDA's findings a Chinese guy overseas was doing EDL unlocks.

Someone mentioned toggling options on samsung phones too. This is helpful in letting the phone work in the engineering rom and some of the phones yes it does actually unlock the bootloader but the use youll get will be zero unless you were performing operations. For example i had an s6 CDMA which i needed bootloader unlocked in order to unlock it for more CDMA carrriers. But sure he is probably correct for the average joe.. its useless..

/end rant.. :more coffee:

I really do hope to see some dev on this phone.. =]

..oh yeah stay away from those auto junk info filled sites they are all bullsh*t info for the most and are simply mass filled with scraped data just to make money and traffic.

    I really want to get this phone and the OEM unlock doesn't surprise me with lgs but what ya wanna bet that LG still removed almost all adb/fastboot commands even after bootloader unlock.

    They've been doing this since the v30 and that's when I left LG. I miss LG.

    If you try fastboot boot or fastboot flash etc, it will say command not found or something unless they changed it back which I hope so cause I hate OnePlus' cameras
    Correction, since the V20.

    It's T-Mobile stripping out fastboot commands.

    well I'm sure eventually someone will find a way to access the bootloader, OEM unlock out the box is a good start...
    Highly doubt it.

    Running, who gained root for the T-Mobile V20 and V30 is done. I don't blame him either. If you read his post on how he achieved it, you will understand.

    Hot damn. I popped up a thread about this the other day asking if anyone had given it a shot yet. So far no Canadian carriers have the phone, let alone buying it directly, so I'm in no position to try it out but I'll be watching this thread with keen interest.

    Just fyi, the phone isn't listed on LG Devs website as being supported by this method (as of this posting): https://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryId=CTULRS0703

    Also, I got a bit dubious, because in some sections of the article, he refers to the phone as the LG V40 ThinQ -- and yeah, it looks like a copy-paste of this article: https://myphoneupdate.com/unlock-bootloader-of-lg-v40-thinq/, The LG V40 ThinQ IS a supported device, BUT ONLY THE EU MODEL. In fact, if you live in the US, my hunch is you'll be SOL, and only the EU V60 Tq will be bootloader unlockable.

    Edit: Both articles on this site look like just the official LG documentation with some words changed and some links to go get things like ADB: https://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryId=CTULRS0702

    I would never trade the battery life in this phone for the McLaren battery life. I'd have to cry myself to sleep every night.


    I have the 7t currently and the battery life is very meh for me and I have the screen at 60hrtz.

    But the hope of root for TMobile v60 seems hopeless unfortunately so I guess I'll be going with the OnePlus 8 even though I despise curved screens
