Root LG Leon MetroPCS Stock Firmware

[Playaz]

So I just acquired this device today.. I went ahead and got it completely set-up, and attempted to root via Kingo Root and alas my phone is bricked. After it restarted, it showed updating firmware, and to not remove the USB cable... However, the progress remained at 0% for a good amount of time... I am now stuck with it staying at the boot screen of MetroPCS with no ability to hard reset or any other recovery options...Furthermore, I went into the store and they said I was SOL... Any assistance is GREATLY appreciated. Thanks for all of your time/effort!

------------------------------------------------------------------------------------------------------------------------------Update: Thank you EVERYONE for all of your time, effort and dedication for seeking out a remedy. I was fortunate enough to be able to install directly via the LG Software, so I had a more "simplified" process compared to this miraculous link anyone who happens to land on this page MUST GO HERE TO FIX THEIR PHONE.

Ultimate thanks to dj rios for recommending me Super-SuMe but I went to give credit for the thread, and there's Debra again! Thanks for this flourishing community and I hope everyone's day is simply amazing! I know I'm thankful to have a phone after a month

I moved this to the Root section for the LG Leon phone. It will be the best place where someone will know where to get the stock firmware. Good luck.

Thank you very much Unforgiven <3

@Playaz I am sorry to inform you but there is no kdz for this device. If you brick then you have to buy a new one

@MikeHoncho, Is this a known issue with kingo or something we may need a sticky for?

 

[MikeHoncho]

I've never used Kingo for anything so I am honestly not sure. I always look at high-end device methods when wanting to achieve root, like the download mode method

@Playaz
What guide did you use to root your phone. I'd hate for someone else to follow the same information and end up with a brick.

 

[Playaz]

Kingo... I've used it on a multitude of my phones, but unfortunately let me ignorance get the best of me and didn't do my research. Been working on getting somewhere with this phone, but it doesn't seem plausible. Can't stay in download mode, transitions to Firmware Upgrade.... Hard Reset doesn't do anything and the LG User Support Tool is of no help...

Check reports, we may want to consider more.

Rooting via exploits can carry higher risks.

Sorry @Playaz.

Kingo root... Not good for this device... Only one_root_click passed the test safe to go.

Have you figured anything out yet? I just did the same exact thing today. Stuck on metroPCS screen with same results.

yeaaaa. you should have not used kingo. KINGO causes bricks. KING root does not.

I actually used a different method that I would have to find the link to now, not the king* method.

Stay tuned, I'm uploading my system.img (rooted) to Google drive for those of you who need to unbrick. A windows computer WILL be required.
I will make an unbrick thread with instructions.

Thanks a ton!

Any luck with system.img

If @Bichofelix is taking the approach I think he is (dd command) then he will be giving himself a headache for a while. Send_Command didn't like the dd command when I was messing with it

I am. I restored boot with it but idk how it'll act with system.
I'm at work right now though and this phone doesn't have enough internal to cache the whole thing for uploading.
I guess we'll see since its our only unbrick method.

Hey wait, if he's booting straight to dl then doesn't that mean his boot is corrupt?

 

[MikeHoncho]

Could be, depending on the kind of exploit Kingo is. I don't know if it's a kernel exploit or not, haven't looked into it

I wiped my boot to see if fastboot was hidden behind it and it booted me into dl. (I think now it's a pin on the board like the gs3 was, I'd have to see the schematics.)

Hmm I think I'll PM him and we'll start there and I'll make the unbrick thread after testing.

 

[MikeHoncho]

Alright, I wont be around later because I leave for work at 3 but I will be sure to give your thread a look when I have the chance

For reference I was rooting via http://forum.xda-developers.com/showpost.php?p=60589870&postcount=2 which lead me to http://forum.xda-developers.com/android/development/guide-root-method-lg-devices-t3049772

After restart, stuck on metro pcs screen.

That's the exploit we need to fix your phone. Basically you'll go through the root process again via download mode, then at the end I'll have you issue dd commands with the .img on your external (internal isn't large enough) and hopefully it works.

I'm at work until 6 and am also in the process of moving but I assure you I will find some time.

Edit: here https://docs.google.com/file/d/0B49eSz3ZJIn0N2k3SFR3elI0aFE/edit?usp=docslist_api
This is boot.img
Put it at /sdcard
Go through the download mode root process all the way to the end. Youll see '#'
You may now input commands.
Use

dd if=/sdcard/boot of=/dev/block/bootdevice/by-name/boot
