[STOCK][H872][20a] T-Mobile G6 Stock SysBoot ROMs (Stock and Rooted) - T-Mobile LG G6 ROMs, Kernels, Recoveries, & Other

T-Mobile G6 H872 20A Stock SysBoot ROMs
Based on OEM 20a KDZ. Extracted and Repacked.
DISCLAIMER
Proceed at your own risk. I am not responsible for any damage to your device.
This ROM will only work with the 20a Bootloader.
If your phone is not on factory 20a firmware, and you are not able to flash the 20a Stockboot found in Eliminator74's Stock 20a thread, you should not flash this ROM. If you do, your phone will not boot to the OS. It will hang on the boot logo indefinitely which will burn out your device.
These Zips only contain System and Boot firmware. They do not include the bootloader or modem.
Instructions
If your phone is stock, make sure it has the 20a bootloader.
If it doesn't and you want to run this rom, you will need to flash it. Use Eliminator74's Bootstock zip.
Attempting to run this rom with 11g or 11h bootloaders will not work.
Running 11g or 11h bootloaders could potentially burn out your device since it causes a hang on the boot logo.

Reboot to Recovery TWRP
Make a Full Backup
Safest Method:Clean Flash
In TWRP... Wipe->Format Data
Reboot to Recovery
Wipe->Advanced Wipe->System, Data, Cache, Dalvik
Flash SysBoot zip
If you flash SysBoot with Magisk, you are good to go. Otherwise flash Magisk to maintain root.
Reboot to System
You might be able to get away with a dirty flash or just a wipe of all 4 partitions without formatting. But there is a likely chance you will have issues due to encryption, (which formatting will remove)
Your phone may reboot once or twice during the initial boot to system. This is normal.
Your phone might hang on the boot logo screen. If hang persists longer than a few minutes, hold vol-down+power to reboot the device. It should then boot normally.

MENTIONS & THANKS:
I would like to say thank you to @squid2 for his hard work in building the Squid TWRP custom recoveries and Squid Kernels for our Osprey devices. I would also like to thank @lost101 for taking the time to educate me on the subjects of update-binary and updater-script.

4. Install the Baseband updater (OPTIONAL);
4. Select "INSTALL" from TWRP's main screen and navigate to the location in which you saved the ROM zip. Commence with installation. Flashing will complete in approximately 2 to 3 minutes. Wipe dalvik cache. Reboot system. NOTE: first boot can take several minutes. Just be patient and don't interrupt the process.
You should now have the latest stock Android 6.0.1 installed on your Osprey.

I will not be held responsible for any good or bad that results from flashing the files from the herein link. You - and you alone - are solely responsible for your device.
NOTE: This 6.0.1 Stock ROM is from the Sprint compatible variant, xt1548. I have added the official TextNow app to /system/apps/, and have modified eri.xml and apns-config.xml to support TextNow voice, MMS & data services. Otherwise, this ROM is pure stock and completely unmodified. This recent 6.0.1 build for the xt1548 includes an updated Baseband. While not absolutely required, it is recommended that you update your Baseband prior to flashing this ROM. I have compiled an updater zip which will update your Baseband (Modem & Radio Firmware) to the most recent version. Simply flash this zip using the current TWRP recovery. This updated firmware can increase signal strength and/or download/upload speeds. This updater zip can be downloaded here: https://drive.google.com/file/d/0B1Sfod4HWfk2blpURnRIVjg3WDQ/view?usp=sharing
For users coming from 5.1.1 Lollipop, or users who have never flashed a stock 6.0.1 firmware package, it is strongly recommended that you flash this Bootloader & Partition Index Updater via TWRP. Simply install the zip and wipe dalvik cache once it installs. WARNING: Ensure you have at least 50% battery life prior to installing this zip, and never, under any circumstances, interrupt the process. A battery going dead or user interruption during this installation will almost certainly hard brick your device. NOTE: Should you ever wish to downgrade back to stock 5.1.1, do not attempt to downgrade the bootloader (bootloader.img) or the partition index (gpt.mbn). Simply skip these two files during the fastboot flashing queue, and downgrading should go smoothly.
I want to give my thanks to @FlashnRom for his thorough testing of this ROM and the updaters. His testing made the current stable version possible.

Don't update the baseband with that zip
I love the ROM, it works really well, but after flashing the .zip that updates the baseband, the rom became unstable and would always reboot 30-60 seconds after being turned on. This happened in a constant loop. Upon reflashing and trying again, the problem persisted. I reflashed one last time without it, and it worked without the problem. once again, love the ROM, hate the baseband updater.
Anyone know what could cause this?

I don't know if this is related but I just flashed the textnow stock .zip and now TWRP touchscreen capabilities are gone.

Probably not related, but I may add this to the OP, a wipe of cache and dalvik/ART should probably be performed after flashing the ROM. On the baseband issue, I just determined the problem. I need to include in the baseband installer a command and files to update the bootloader and partition index. Because if you are coming from stock 5.1.1 on TextNow, your partitions and bootloader need to be updated to 6.0.1. Thank you for your user experience and input. I will write a script to correct the issue and update the thread accordingly.
How can I get permission of Google Drive to download for the baseband updater and bootloader?

New to device and the whole firmware thing

OK, long story short. Came for the nexus 6 and nexus 6p to oneplus 3t. The 6p had to flash vendor.IMG after every new ROM flash. But what is this whole firmware thing in this device? I have tried to find answers before asking but, what should I DO and NOT DO to have a brick? Like, wanting to go from a nougat ROM to an Oreo ROM, but not sure how. And then if I wanted to go from a n/o ROM to a beta, not sure how...then if I wanted to downgrade from an o or beta ROM.......please help
Treat the OP3T pretty much the same as you would the Nexus 6. The only difference is, like you've discovered, that OnePlus provides firmware files rather than factory images.
The installation instructions for the different firmwares (stable and beta) are found in the first few posts of the respective threads:
https://forum.xda-developers.com/oneplus-3t/how-to/rom-oxygenos-3-5-4-mm-ota-update-t3519074
https://forum.xda-developers.com/oneplus-3t/how-to/coming-update-oos-based-7-1-t3564240
It's pretty much the same as flashing vendor image. OnePlus just simply offers Firmware images which flash the Modem and the Firmware.
If you're gonna be on OxygenOS and Custom OxygenOS ROMs then you wont need to worry about flashing the firmware. Some of the Custom ROMs such as Paranoid Android and PureFusionOS also flash the recommended firmware automatically.
However, others don't and require you to flash a particular fimware image manually. Usually the Firmware to be used would be mentioned on the ROM thread itself.
Once you've Unlocked the bootloader and flashed a custom recovery, The most common process for flashing ROMs which do not have an included firmwares goes as follows:
1. Reboot To Recovery
2. Wipe Cache & Dalvik Cache, System and Data Partitions
3. Flash Firmware
4. Flash ROM Zip
5. Flash GAPPS
6. Flash Magisk/SuperSU (Optional).
7. Reboot
And that's it.
That is the standard procedure for most of the ROMs, but, I'd advice reading the OP Instructions properly first in case theres anything different.
PS. For moving to Oreo from Nougat, follow the same, but be warned, If your current ROM is encrypted and the new one isn't you'll be locked out of your device until you flash the old ROM back OR wipe userdata with fastboot, which wipes the Internal Storage.
PPS. For moving from a Custom ROM to Oxygen OS, best way to go would be to flash the official recovery again and sideload the official ROM zip via ADB (In some cases, encryption still might cause the same issue as above)

That was very informative, thank you!!! Just one more question tho. What would happen if I didn't flash the correct firmware? Like, there is a RR ROM with custom sultan or something that looks like it needs a beta firmware, I'm not in beta firmware, so would I have any issues?

I'm not entirely sure but in most cases the ROM would simply refuse to flash. Like for RR, if you don't flash a correct firmware then the flashing returns an "Error 7" and the installation stops. But even if it does flash through, it would either not connect to a network or get stuck in a bootloop, but nothing too serious which you can't rectify.

[GUIDE] [F.A.Q.] [chef] [TREBLE] Common Hurdles and Solutions for First Timers!

This thread is meant to address all the common hurdles that are commonly faced by people who are new to treble devices (chef to be specific) and help them to troubleshoot/avoid some small yet critical steps during flashing new ROMs and working with fastboot and recovery in general. It will be continually updated with new stuff as it goes along.
I will be referring to the Motorola One Power and Moto P30 Note as chef only from now on.
The unlocking guide is available in This XDA Thread!
IMPORTANT:
1. Flashing refers to the process of doing a clean flash, with the inclusion of fastboot -w command
2. Latest ADB and Fastboot drivers are required to be installed, else the installation may halt mid-way.
3. Stock ROM refers to the Android One ROM for the Motorola One Power [XT 1942-2]
IMPORTANT: AS OF RIGHT NOW, PEOPLE WHO HAVE INSTALLED STOCK PIE (EITHER VIA UPDATE OR FIRMWARE) WILL NOT BE ABLE TO USE ANY OTHER ROM OTHER THAN THE STOCK PIE ROM. RADIO INTERFACE LAYER IS BROKEN IN OREO SOURCE BUILT ROMS AND THAT CURRENTLY INCLUDES LINEAGE 16 SO PLEASE WAIT FOR PIE SOURCE CODE FROM MOTOROLA FOR THAT TO BE FIXED.
1. I unlocked my chef . How do I flash TWRP in place of the stock recovery?
Solution:Currently you cannot as there is no recovery partition in the device. You have to manually boot TWRP onto the device using fastboot to use it. Follow as directed:
Boot the device into fastboot mode
Use command fastboot boot <path/to/TWRP.img> to boot TWRP temporarily.
2. I am done with TWRP and I want to flash Lineage OS 16 on my chef. I simply flash the .zip archive right?
Solution:No. Before you flash anything,
Take a backup of atleast your EFS and PERSIST partitions using TWRP and off-load it for safekeeping to restore in future if needed. You can also trigger a full backup if you require.
SUPER IMPORTANT: Flash this .zip file to copy the System A/B partitions. If this step is skipped, you will be responsible to brick your own device. THIS STEP IS ONLY REQUIRED ONCE AND ONLY ONCE IN THE LIFETIME OF YOUR DEVICE! YOU WON'T BE NEEDING THIS THE NEXT TIME YOU FLASH ANY ROM. .
After that, flash your dearest custom ROM and get going.
For Lineage OS 16, follow This XDA Thread.​
3. I am done testing LOS 16, I want to flash a GSI. Shall I use a stock Vendor Image for the GSI on my chef?
Solution:No. The stock Vendor image is causing bootloop issue in most GSIs. It is recommended to use Lineage OS Vendor to flash a GSI on chef. So flash LOS and then flash your favourite GSI.
Also, Super Important: for those who haven't used lineage before flahing a GSI, it is required to boot Lineage OS first before flashing a GSI. ​
4. I am done experimenting, I want to go back to the stock image. How do I proceed?
Solution:Follow this XDA thread for it. And don't install OTA updates directly from the device. It will come in the next step.​
5. I want to install OTA updates on the stock ROM. How do I proceed?
Solution:Follow this XDA post for it. The installation process is described here. You have to be clever enough to get the appropriate OTA update. ​

Anyone have flashed GSI ROM? FOr me after flash GSI HavocOS have bootloop :/
DIdn't flash copy system A/B partitions, stuck on bootloop with custom roms.
Watched some youtube videos and didn't read this post before flashing custom ROM. Flashed Custom ROM without flashing A/B partitions. Now I have a phone stuck on bootloop when done anything in TWRP. or I can use my phone with stock ROM installed by fastboot method.
Installing or restoring anything from TWRP results in boot loop.
Restoring the backup I made before flashing, completes the restoration process normally. But when rebooting to system, TWRP prompts me that no OS is installed. If I reboot anyway, its either stuck on bootloop or reboots to recovery and asks me to try again or factory reset, or boots into bootloader mode.
Installing custom ROM begins with Step 1, takes a bit time and starts step 2 and shows completed. Doesn't echos any comments. But when i reboot, same prompt shows saying no OS installed. Reboot anyway and stuck on bootloop or reboots to recovery and aks me to try again or factory reset, or boots into bootloader mode.
Now I installed stock ROM with fastboot method and phone is boots up into system just fine.
Sometimes TWRP can't mount anything.
So am I stuck with stock rom or is there any solutions?
Also, installing stock ROM with fastboot mode showed this error in between scripts
(bootloader) is-logical:xxx_a: not found
and
(bootloader) is-logical:xxx_b: not found
but is able to use the phone just fine with stock ROM.
