LG G3 D851 Lollipop (T-Mobile US)

Quote:

This thread contains multiple ways to get to T-Mobile's first Lollipop update, 20B. The 2nd post has a custom L build I made which has all the T-Mobile things removed (including wifi/lte calling).


20B TWRP-FLASHABLE ZIPS

LGD851.20B.SYSTEM-iNb4TMO.zip
MD5: 94c75957ae197ec45d0f562a2ae6768d
Stock 20B flashable system/rom... stock... exactly as T-Mobile intended it. Yes, TMO Wifi/LTE calling.

LGD851.20B.MODEM-iNb4TMO.zip
MD5: 62a5522cb71d1f8cc0bde9d0c48f6143
Stock untouched 20B flashable modem. Contains only the 20B modem.img.

LGD851.20B.BOOT-iNb4TMO.zip
MD5: 3d9fc3a5becd198b80c52c66ba0091a3
Stock repacked 20B flashable boot/kernel. Contains only the 20B boot.img.

LGD851.20B.BOOTLOADER-iNb4TMO.zip
MD5: 4f18399a8dbe006df3ad95709b3ed377
Stock flashable 20B boot stack. Contains 20B aboot, dbi, factory, laf, rpm, sbl1 and tz.


Directions:

Must be rooted. Use PurpleDrake or the new LG root floatin' around.
Be sure you are using TWRP v2.8.6 or higher. YMMV with other versions. DOWNLOAD TWRP HERE
Be sure all apps/data have been backed up (Helium/Titanium Backup) if you plan on restoring apps.
Be sure to have an EFS backup. If you don't.. you can make an EFS backup in TWRP or using the directions in my thread.


1. D/L n' flash 4 zips: 20B BOOTLOADER zip, SYSTEM zip, MODEM zip and BOOT zip.
2. Do a factory reset in TWRP (Wipe > swipe)
3. Done.. reboot TWRP into Lollipop. Be ready to wait up to 5min on first boot.

20B Stock Images

These are the untouched stock images from the official T-Mobile Lollipop 20B update for the LG G3 D851.
System.img only comes as a flashable zip.. easy install and saves space. Loose images can be flashed manually or packed in a zip.

Manual .IMG Installation
Code:
dd if=/sdcard/imagenamehere.img of=/dev/block/platform/msm_sdcc.1/by-name/nameofpartitionhere

example: 
dd if=/sdcard/modem.img of=/dev/block/platform/msm_sdcc.1/by-name/modem
*command assumes image is in root of internal storage.

20B OTA UPDATE

D85110r_00-D85120b_00_update.zip
MD5: 204ca98458c4e2f14c35f6694f1f8b3d
This is the 10R -> 20B OTA update zip. Rather than waiting for it to push to your phone from T-Mobile.. you can manually install it as long as you are on STOCK 10R and have STOCK RECOVERY and are ROOTED. Other than root you must be 100% stock. If you deleted any stock apps that were in /system or installed xposed etc there is a very good chance you will not pass the updates system check before the update actually flashes. The update zip patches pre-existing files rather than adding full new files.. this helps keep the OTA zips file size down... and is also why ALL system files and your kernel/boot partition is checked before it flashes. The zip will FAIL if you have TWRP installed.

1. Download the OTA update zip from the D851 20B folder HERE
2. Copy the update zip into the cache folder (this is why you need root) then rename it: update.zip
3. Open Phone dialer > dial 3845#*851# > select WCDMA-Only -- DM/FOTA Test -- internal -- update
your phone will reboot then show: "Installing system update" with the lil green android guy. wait... done.

You will lose root after the update and be 100% stock again.

20B KDZ Method

T-Mobile D851 20B KDZ
To flash the KDZ manually read the thread HERE. Flashing KDZ will remove TWRP... you'd have to re-root then reinstall TWRP (if you even wanted it of course).

LG Mobile Support Tool
Download this Windows-based tool to update to 20B. This tool auto-downloads the KDZ and installs it for you. Install... run and follow the onscreen directions. If the app doesn't seem to start the upgrade try manually selecting: Options > Upgrade Recovery
@Chrishup has posted a rundown of how he updated using the Mobile Support Tool HERE.

Custom Rom

LGD851.20L-ollipop.I.UNICRON-iNb4TMO.zip
MD5: f1de51acffe17435c8172b4b0cd28cbc
This rom/kernel is not to be repacked or used as the "base" in your #yoloswag420 rom.
*This rom comes with a kernel so a boot.img or boot zip is NOT needed.

LGD851.20L-ollipop.I is a fusion of LG's 5.0 and 5.0.1, including some 20B bits. It has all things "T-Mobile" removed from the rom (except APN). If you don't need any T-Mobile features and want a minimal/debloated stock LG Lollipop experience this may be the rom for you.
LGD851.20L-ollipop.I's UNICRON build is most likely the final build for "v1". LGD851.20L-ollipop.II will start up when newer LG builds are available, most likely with Android 5.1.

Few Highlights:
Debloated
Stock LG Lollipop, no "tmo-ness"
Built-in PrimeTether
Rooted + Busybox
Updated Firmware
Ext-SD card Write Mod
Built-in kernel certified by savoca®
Supports @savoca's great mods:
on-the-fly screen sharpness on/off via Whetstone
display calibration with his KCAL Color Control app
Certified SAVOCA kernel is GPL-compliant

Whetstone - Download HERE
Color Control - Download HERE
KCAL/Color Control Videos - HERE and HERE




Directions:

Must be rooted. Use PurpleDrake or the new LG root floatin' around.
Be sure you are using TWRP v2.8.6 or higher. YMMV with other versions. DOWNLOAD TWRP HERE
Be sure all apps/data have been backed up (Helium/Titanium Backup) if you plan on restoring apps.
Be sure to have an EFS backup. If you don't.. you can make an EFS backup in TWRP or using the directions in my thread.


1. D/L n' flash 3 zips: 20B BOOTLOADER zip, UNICRON zip and MODEM zip.
2. Do a factory reset in TWRP (Wipe > swipe)
3. Done.. reboot TWRP into Lollipop. Be ready to wait up to 5min on first boot.

Upgrade to Lollipop and can't download anything or write to internal sdcard? Fix yo permz. This doesn't fix extSD issues.
