[STOCK][H872][20a] T-Mobile G6 Stock SysBoot ROMs (Stock and Rooted)

[weakNPCdotCom]

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.

Please let me know if you have any issues with these packages. Thank you!

Announcement
I have officially moved to the V30 and no longer own the G6.
I will still be active in this community, but since I don't have the device any longer I will not be able to test any packages or issues that might arise.
All of my current projects have been tested. If anybody runs into problems, you can still let me know and I'll do my best to support my stock packages.
Thanks guys!

Is this the file from eliminator you say we should be flashing first?

LG-H872_Oreo-20a_Bootloader_B2.zip (WO/LAF)

I'm thinking yes but y'all worded it differently so wanted to double check

Yes but from what I have gathered his zips have some verification issues at the moment.
