Root Bootloader

[qandres12]

How come previous lg devices have had their bootloaders unlock? Did lg just suddenly start being evil with their bootloaders.

 

[Swainsmith82]

I know the M+ was unlocked and available for CM recovery. I don't know when they started locking them but my guess would be on ics and later. I one don't think enough time was spent on unlocking ours in the beginning and two it appears to be damn hard.

lg wants their devices locked, its a smart business decision

And buying something other than a new LG product after owning a Connect was a smart decision on my part. If I had one inkling of hope in somebody unlocking the LG bootloaders, I totally would have bought a Spirit. Even in the case that it was never unlocked, if it weren't for the ugly inverted IDKWTF kinda ICS UI they puked up I would still buy it. I like to theme my stuff, or at least have the Vanilla ICS if I can't have anything else

Two powerful phones (770/870) with great potential that are locked up until 20 years after EOL is a damn shame. If I really wanted to use a phone for what it's meant to do, how the phone's manufacturer wanted me to use it and if I enjoyed wearing turtlenecks and bunny slippers I'd have an iPhone already. But looks like Android manufacturers are still going the Apple route, despite hearing that some were considering selling phones unlocked?

I bought the Spirit with the express intention of unlocking the bootloader.

 

[Swainsmith82]

It kills me about how many Lg bootloaders have been unlocked but not these. If the o4x rooting process was so similar that we were able to use it on the m770 could the same be said for the bootloader? I know you have to get a signed key but is that even obtainable? It has to be right?

I'd love to see an unlocked motion in my lifetime, it would be one of those events remembered world wide. Like when we dropped the nuke

By back door to fast boot do you mean getting your phone to boot into it b.c I did on accident on the spirit flashing things I shouldn't have. I had no idea what to do so I just pushed back my boot image.

Nah, all you have to do is wipe the boot partition for that. If you look in the disassembly there are two different fastboot loops. One is the normal one (with the oem-unlock stuff hardcoded out via a hard jump), and the other one is labeled "BACKDOOR". The backdoor'd fastboot looks like oem-unlock is accessible (it actually has an entry in the jump-table unlike the "normal" fastboot), but still requires a signed certificate from LG.

ROM:0002C9AC aBootWithLgeSpe DCB "boot with lge-specific reboot code(0x%08x)",0xA,0

Anything to do with the backdoor?

Negative.

Lets keep matters on topic, lets agree to disagree and move on, name calling is not called for, if you have an issue with a post, simply report it rather then adding fuel to the fire. Thanks all for understanding, and lets all get along.

Well put

 

[Swainsmith82]

Im just brainstorming here, would it be possible to decompile the kdz and use a similar method like on the L9

Ok so reading around I see how emails and petitions to LG have been successful in getting them to unlock the bootloader through an ota update on some devices. I think this might be be our best option at this point.. Ive already sent two emails to them. One I've already got a response to saying we cannot access the bootloader which I already knew. The second i was a little more forward and direct. I still haven't received a reply on that one as of now, which I'm taking as a good sign considering they replied within minutes to the first.

The LG signature tools were leaked for the Optimus 3d I believe it was. Not sure if its the same tools used to sign these partitions but worth a look perhaps.

This looks interesting, did you try to sign a boot or recovery with this yet ?

 

[omgbossis21]

Actually no. I no longer have a motion, I got an l9. When I have time to see how this works I'm going to see if it works for the l9. Just haven't forgot about the motion community
Edit ... trying now but can't get furthur than executing script and it errors on unpackbootimg and mkbootimg not found even though they are there. This is testing on cygwin though it should work
Edit... both those images are binary and cygwin won't run them so I modified the LG script to work with the cygwin modified image pl's and it work but a few of the LG files are binary. Doh! Now attempting on my Ubuntu build but last time it crashed it was left in pretty bad shape lol.

 

[sammyz]

I'm also trying, almost done building....CM started a random error where I had to delete 1 line of code to pass it....hopefully it was unimportant which I think was unimportant.

Someone flash this via fastboot or dd

I did not flash it, I can tell that it is not signed by examining it with a hex editor

 

[omgbossis21]

OK I got it working after fixing my Ubuntu build and installing 32bit libraries since I decided to try out the 64bit Ubuntu. I only signed a recovery image for the l9 and used adb reboot recovery which gave me a android with a triangle (not a secure error). I'm not even sure its signed on this phone lol. I unpacked/modded/repacked my boot. Img and will test tomorrow. If you guys link me to your boot. Img I will mod it and sign it tomorrow and you can test it if nobody else has done it yet.

i tried it, and it did not work for me, I get the certify error

I examined what the signature looks like when it signs it, and it does not look like it has the same format as the stock signature


you have to realize that wkpark found these keys / keytool in a Ginger Bread source that LG put out by accident, so I am sure a lot has changed since then

I find it interesting that you got that triangle and not the error, so maybe you should experiment and little more, maybe we did not use the same method

for the record i did

unpacked stock recovery and repacked it
and then did

./signimg.sh recovery.img
