Root [GUIDE] Brick Recovery

[spunky168]

This guide is intended for recovering from a brick where you can't access recovery or boot the phone. If you can do either of these, you are not bricked and this guide is an extreme solution to your problem. Access to download mode and a computer is required.

Several of the files have an MD5 listed below them. You can use this to verify that the file downloaded correctly. Install this hash checker and compare the MD5 of your file to the one listed. (Android MD5 Checker)

Step 1 - Gather materials for zv3 downgrade
What you will need:
zv3 stock tot file - DL to computer
MD5 = 0D7AAAFB6742CEAB7BCAEECBAE3C1F39
LG Flash Tool 1.8, Megalock, and LS740 - DL to computer
MD5= C1825BA208611B23B9B0D4aBDD0C5731

Looks like it was a system issue:

SYSTEM NOTICE: We are working on the load balancer's. You may get a few 502 error pages but if you refresh they will go away. This will be fixed shortly.

Okay, so I got the files downloaded. Seems androidfilehost was migrating. Now I can't boot into download mode. It just keeps loop booting back into CWM Recovery v6.0.3.7 despite following the first post instructions. Anyone have any additional advice? Thank you.

Why do you even have CWM installed? You should be using TWRP.

Holding Vol+ while plugging in the USB with the phone off is the only way I know of to get the phone in download mode. There's probably an adb command you could try, but it likely won't work. I don't know if that CWM is part of your issue? What's wrong with your phone?

My understanding from the phone owner is the following: she had originally rooted her phone when this forum (LG Volt at its infancy)started and at that time CWM was the only working recovery. She was running ZV5 rooted deodex full rom. Everything was fine until she got a notice and took the OTA update unaware that she should not have. After downloading, and installing the OTA update, her phone went into CWM recovery and no matter what option she picks, it bootloops back into CWM recovery even if she chooses "power off"

I am glad I am no longer using the Volt even though I have some strange affinity to try to make this phone work again.

Thanks in advance for any advice.

Will this http://androidforums.com/index.php?posts/7281141 work? Or is that only if you already have twrp? What I don't understand is how she only got the update now if it came out like eight months ago and it nags you to update it.

andMego,

A thousand thanks. I took your advice and followed the link. I had to modify the instructions and scripts slightly but the phone is out of bootloop. TWRP is installed and the phone is back to its manufacturer's original state. Now I have to get to work and root it and declutter. My friend and I owe you big time.

Thanks a lot.

While you are waiting for someone to answer you I would suggest you read the rest of this thread and the other threads like this (for example http://androidforums.com/index.php?threads/1048039/ although I'm pretty sure you aren't as badly bricked as that guy was)
Also I suggest you try a different computer or and make sure you installed the right drivers

So I noticed this guide is used for phones that arent able to get into stock recovery.. well I'm wondering what is my next step? My phone is stuck in a boot loop.. I've tried clearing cache from stock recovery, did not work.. Whats my next step to avoid losing all my info on the phone? I don't have a backup available.. Stock recovery gives me option to update via external sd, adb, etc... or to reformat...

I downloaded all the stuff here needed.. but would like to try to save photos before I go thru with full replacement.

This guide saved my practically brand new LG Volt. I tried rooting methods on it as soon as I got it and messed it up and ended up just throwing it in a box and leaving it there for close to a year. It finally works again. Thank you so much!

 

[DELTA9R]

My pc won't let me in the port settings to change the com41 part. Please help!

 

[DELTA9R]

I was able to change port to 41,but now when I press yellow arrow on flash tool it says .. failed previous load. help!!


FIXED with reboot I think.

Thanks for guide to fixing my volt

Works like a charm. Got in a pickle after testing a method to resize our devices partitions so we would have more memory on hand.

 

[erogier]

This guide worked perfectly! Although I could access recovery I was unable to get the phone to load past the lg screen. Also my computer didn't recognize the phone.
Anyway, a great big thank you to all who worked to put this fix together!

I am having the same problem.....I read the same thing about laf.img . The fix was to grab a copy of radio.img from a ROM and flash with fastboot. I tried this but it didn't work for me. My problem started with a bootloop. I hope someone will respond and you get some help!

 

[Constantinos Morfakis]

The downloaded drivers name is LGMobileDriver_WHQL_Ver_4.2.0.exe. instead of 3.12. Will this work with the updated drivers?

 

[Travis Kinnett]

thank you sooooo much. Still works to this day. Bricked this and got a volt 2 stuck in bootloop so i tossed them in a junk drawer. Got them out to tinker with...on to the volt 2.
