This is for LG G3 D851 ONLY
TOT/KDZ/TWRP Untouched stock restore​

IF YOU WANT TO USE THIS GUIDE WAIT UNTIL I HAVE THE LGUP METHOD UP

Who can benefit from this?
  • Anyone who softbricked with access to download mode [KDZ RECOMMENDED]
  • Anyone who wants to use the OTA function after root [TWRP RECOMMENDED]
  • Anyone who needs to send the phone in for repair [TOT RECOMMENDED]
  • Anyone who wants to be on the most recent firmware [TWRP RECOMMENDED]
  • Anyone who wants to downgrade *After you update to 20B it is recommended to not downgrade. If you do you WILL have connection problems
  • Anyone who wants to return to stock from aosp or aokp
    • Tip: Most of the time TWRP will do what you need without the troubles and baggage TOT and KDZ bring. It will downgrade, upgrade, root, fix soft bricks or just give you a fresh untouched operating system (no personal data left on the phone if you follow instructions). It will also get rid of any proof on the phone that you were rooted (my t-mobile reports root to a remote server nothing can be done about that).

Strengthens and weaknesses for each method click here

TWRP Files/flashing guide Most recent = D85130g_00_0420 (07/05/17)
(This is a WIP)
  1. Download your preferred choice of D851xxx-Untouched_Stock_Restore.zip HERE (Perfect 1:1 image unlike most roms)
  2. Copy D851xxx-Untouched_Stock_Restore.zip to phone (external sd if available)
  3. Reboot into twrp
    • For firmware update do not wipe! skip to step 8. If you want untouched stock continue with step 4.
      If upgrading from kitkat to lollipop wipe system before flashing.
  4. Click [Wipe]
  5. Click [Advanced Wipe] (For full wipe stock restore only)
  6. Select dalvik cache, system, Data, Internal storage (only if you use external for downloaded file) and cache
  7. Click the home Icon in the bottom left
  8. Click [Install]
  9. Select D851xxx-Untouched_Stock_Restore.zip (make sure you select the proper sd card)
    • If you want root and/or twrp add UPDATE-SuperSU-v2.37.zip to the queue by touching [Add More Zips]
      Repeat for TWRP-2.8.6.0-d851.zip
  10. Swipe to install [====>]
  11. Install will now begin, pure stock: system, kernel, recovery, modem and rpm will be installed
  12. After completion click [wipe cache/dalvik] (do not skip especially if you dirty flashed)
  13. Swipe to wipe [====>]
  14. Click [back]
  15. Click [reboot system] (it might say no os but it is wrong you do have a os click restart anyway) [dirty flash will not have that problem]
  16. If your sending for repair or jump do a factory reset with what should now be the stock recovery just to be safe.
DO NOT INSTALL ROOT UNLESS YOU WANT IT TO BE ROOTED


LGUP (KDZ/TOT)

KDZ FLASHING GUIDE

Very buggy on windows 8/8.1 x64 YMMV
Will not work on windows xp or older​
Click to expand...
Click to collapse

  1. Download, extract and install LGUnitedMobileDriver
  2. Download, extract and install VBCFJRedist_AIO_x86_x64
  3. Download and extract LG Flashtool 2014.7z (This is not the same flash tool in TOT method)
  4. Download one of the KDZ files from the beginning of the post and extract it in the Flashtool folder
  5. Make sure you are at least at 50% battery
  6. Enter download mode by holding the volume up button + plug the phone into the computer from a powered off state
  7. Run LGFlashTool2014.exe as administrator
  8. select type [CDMA] (Yes CDMA works just fine for our T-Mobile GSM phones DO NOT USE THE OTHER OPTIONS)
  9. phone mode [diag]
  10. reset time [33000]
  11. select the KDZ file you extracted from inside the flashtool folder (D851xxx_00.kdz)
  12. select [normal flash] (no wipe) or [CSE flash] (wipe) (Recommended)
  13. click [start]
  14. Select Country and Language Just leave default selections and click OK (Republic of Korea is the only country and it defaults to English)
It will analyze the phone extract the firmware and upgrade your phone automatically you will see progress on both the computer and phones display once the s/w upgrade percentage gets to about 80% your phone will restart don't freak out all went well and it will boot up to the LG welcome screen and if you selected CSE it will restart one last time

Total flash time for me was 2 minuets 56 seconds

If you use the normal flash you might need to do a factory reset if you get in a bootloop after flash
cse should have 0 problems on boot

Your phone might automatically reboot on 3 but it hasn't for me If it doesn't just pull the battery put it back in then power up. After one of the updates this step may be different then described. If you have problems just ask and myself or somebody else will be able to help.

Great guide! Just what I was looking for. 2 questions though... Will this unroot your device? (I would presume untouched stock means that, but you know what happens when I presume. I make a pres of you and me). (I'm looking for a reliable to way to uproot, just in case I want to get an OTA). Also, could you link to the G3 drivers in the OP? This is gonna be my go to post if anyone asks me about it... :D

Worked for me on 8.1 so it should work for you. Install Microsoft c++ runtime 2012 or 2013 then try again. Also make sure you have the proper drivers installed. Ill upload both runtime and drivers when i get home so if you cant find them check back around 6 or 7.
*Edit
Also make sure your running as administrator.

Thanks!
It will unroot you and it already saved my butt after I accidentaly formatted most of the partitions on the phone. I plan on uploading the unified lg drivers tonight along with c++ runtime. Im also going to hunt down a nice guide and link to it for flashing via the lg suite if this fails. The lg suite way is a pain in the a** but should work if this one fails.

If you need drivers for Windows (thanks @autoprime for having these handy!):

UPDATE
1- I downloaded 2013 Runtime 2013 from here: http://www.microsoft.com/en-us/download/details.aspx?id=40784
2- Rebooted my PC
3- Followed the instructions in OP, performing the CSE flash.
4- Received a timeout error really quick but it started to flash.
5- Around 80% the phone went black and never booted to the LG screen, after it hit 100% I unplugged it, removed the battery and rebooted it.

Booting up it entered some mode for a split second and rebooted itself.
Once on homescreen, it rebooted itself one last time.

I'm UnRooted now :)
I guess i needed to install C++ Runtime
Thanks

    and
    TWRP installer zip

    *Important information Below*

    • Wipe everything except internal and external data for the best lollipop experience. But if you must dirty flash you MUST wipe cache/dalvik and system or you WILL bootloop. You could skip wiping system but problems might happen.
    • If you did dirty flash it might take a long time to get to and from the T-Mobile screen. If it takes longer than 5 minutes to get past the T-Mobile screen pull the battery wait 10 seconds and power it back on then it should bring you to the updating android screen, give it time.
    • After a reboot update your apps ASAP
    • If you downgrade from lollipop your phone will need to reboot several times before it recognizes your sim card. You will also need to format system before downgrading. If you downgrade with twrp you need to format system before flashing.
