[T-Mobile LG V10 General] warBeard_actual:
ADDED INSTRUCTIONS AT END OF POST*****

Got it.... Rooted, twrp, the whole deal. On 6.0. I'll post instructions in the middle of the week for everybody.

Unfortunately if you already did the other method, you are screwed for now. Because the method I used required me to flash a stock 5.1.1.

So there I am sitting on my computer last night, when a notification pops up on my V10 .... The old "congratulations, you've won first prize in an update contest!"

Lo and behold, the MM update had downloaded (at record speeds I might add).

Without wasting a minute, I navigated to the cache partition and copied it to my internal folder (see attachment), then backed it up on drive.

So... We'll just skip to the good part...

I'll save you all the curiosity and let you know that I am going to look into this option to flash the OTA this weekend. I'm going to assemble a compatibility analysis and if everything checks out, I'll flash it.

Standby for carnage.

****INSTRUCTIONS

OK... I really owe everybody here an apology for taking so long to get an official instruction up. Work has been crazy this week. But I wanted to be able to take some time to do this. So here we go...

But wait... Before we even start, please for the love of God do your homework here. Please go read through chains thread about his app, how it works, etc. The interface is straight forward enough, but there are other things to understand. Please just understand what you are doing, and please verify checksums of anything you download. This is very important.

And thank chainfire, not me.

PRE-FLASH REQUIREMENTS:

1. First and foremost, you MUST be on the latest version of MM TWRP. There is a thread in the development section for this, with instruction on how to flash it, find that thread. Get it installed. This is a must. You must also verify adb and fastboot are working fully on your device.

2. You must be 100% Stock (but rooted) on the latest TMO V10 5.1 1 firmware and ROM, no custom kernels, nothing. Stock, with the exception of working root, and the latest 3.0.2.0 Marshmallow TWRP. When I say stock I mean no deodex, no system apps removed, this is an absolute requirement. The reason for this is mostly to avoid the update.zip from aborting as it does checks for presence of apps within system, etc. If you have to flash a stock ROM before doing this, don't do it as an "in line" queue before you flash the OTA in flashfire. Do it separate.

3. You must have the official OTA downloaded and on your internal SD card. Also, put the latest superSU version 2.67 on an external card, and remove the SD card from the device. The md5 for the OTA is 280ad51eb96457df097df5a088a535af9

Once you have checked those 3 boxes. You are ready to proceed.

4. Install flashfire. I was on version 32.

5. Open flashfire, grant it root

6. Go into the setting of the app, check the "Flash boot loaders" and "Freeload" box.

7. Find the OTA package, queue it up with "flash zip or ota" (small + sign at the bottom right of the screen)

It is important to note that after the flashing process completes, you will want to power off the device, and boot it into fastboot mode to unlock the boot loader.

8. Execute the update.

9. After it finishes, power off the device.

10. Boot into fastboot by holding down the volume down button, and with the button held down, plug the USB cable into your computer.

11. Once in fastboot, type the following command and hit enter:

fastboot oem unlock

Let it run for a bit, it is going to wipe your data.

12. After it completes (your terminal should give you a time displayed for the operation).... Unplug the phone, and yank the battery.

13. Pop in your Micro SD card (with superSU 2.67 flashable on it) then manually boot the phone into recovery mode. You are going to flash superSU again as a sanity check. I did this because if for some reason FF didn't flash superSU, and then the system wrote over your recovery during your first boot... You'd be absolutely dicked stuck on stock MM with no way of getting root back for now. I like verification...

To boot the v10 into recovery mode manually, simply have the device powered off, then hold the volume down and power button at the same time. AS SOON as you see the boot screen (not to be confused by the boot animation) released the power button for just a little less than a second then press and hold it again (keep the volume down button pressed the whole time). It may or may not be absolutely critical that you don't screw this part up. You need to get into recovery at this point to validate root being installed.

This should take you into 2 sequential screens, both asking about clearing data, select yes for both (don't worry, it won't, it will take you into TWRP.

Once in twrp... Mount your SD card in the twrp settings, and flash superSU.

Reboot afterwards. Done.

After you do this, you will be in 100% stock, rooted MM.

You might need to flash twrp again (do it the normal way, you are done with flash fire now), but root, you will have, and full functionality, you will also have, with everything working.
