Lineage OS 20 to Stock OOS - Problem - OnePlus 7T Questions & Answers

Hi All,
I have had purchased this T-Mobile Oneplus 7T which was already converted to Global/International variant. SIM Tray was changed so dual sims were working. I installed LineageOs 20 as directed by them on the official website. I had to flash 2 extra partitions in order to get it installed properly. As it is described (dtbo and vbmeta)

"lightbox_toggle_sidebar": "Toggle sidebar"
}
But I guess on LineageOS 20 Dual Sims are not supported. So Now I want to get back to Stock OOS Android 11 for the dual sim functionality.
So I first tried to return to stock rom by using this method of flash -all.bat. As described here
But it didn't work.
Then I moved over to MSM Tool but all in vain. I am getting random errors. Sometimes 'No valid trg' sometimes 'param preload failed'.
I tried MSM tool with both Indian/Global Roms as well as with T-Mobile ROM.
I would be happy to know if there is any ROM available with Dual Sim Support.

No I didn't have them before and I flashed it with LG FLASH TOOL because I didn't got the update and I flashed this version - LG G3 (32GB - D85520E_00.kdz) - Open Europe (LG)..
that is because the mobile IMEI is Singapore , unfortunately i thing we cannot change the region ,

Hi,there is a simpler way to get OOS: Download the OOS from oneplus' official site , put it to the root of the storage,then go to Settings-System Update,tap the gear icon and choose local upgrade,select your OOS package.System will upgrade automatically and userdata won't be deleted

How to update

Hi guys, I'm from Argentina, I currently have this version of LG G7: LMG710RM (It's a version only for Argentina)
https://www.lg.com/ar/celulares/lg-LMG710RM
I've already owned and flashed LG phones, but with this one, I still don't feel safe to do it, therefore I need help.
My phone is still in the Oreo version, so as you can see the updates for my mobile version are delayed.
Looking at the LG open source page, I can see that my cell phone uses the following firmware:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
(It is a software version of other cell phones, they have not released a software for this special version of Argentina)
My cell phone is unlocked. So my question is: Could I flash the Android Pie KDZ file of any of these versions (LMG710VM or LMG710AWM or LMG710VM)?
or could I flash the version of global kdz for example? (LMG710EM)
since I don't see another possible way to update my Android to the Pie version
I appreciate the answers.
Greetings

I offer my phone as tribute to port twrp

I am currently in possession of a carrier unlocked Razr 5G with an unlocked bootloader, that I have rooted via a Magisk patched boot image. I don't know the first step in porting TWRP to this phone. However, if someone will work with me, I will gladly offer my phone to do so.
I have a friend working on it.

I'll release in a bit, just working on touch
Noice... should take a look to see if GSI is portable to this thing, I'm looking forward to this be my next upgrade (Maybe an incentive to keep my next job and keep on with the plan payments, lol), so I want a phone that can run real programs and have my handy DriveDroid install ISO's into work servers and stuff... Still running on a rooted Honor 5X running android 9 since it's capable of doing that stuff and still cuts it for my needs running OmniROM

[TWRP] Is twrp-3.6.1_9-0 supported on Android 12 (LineageOS 19)

Hello,
I have flashed twrp-3.6.1_9-0-cheeseburger_dumpling.img successfully using Fastboot.
However I cannot decrypt my phone when booting into recovery.
Any attempt entering my PIN fails with error:
Failed to decrypt user 0
This error occurs since upgrading to LineageOS 19.
And this drives the following question:
Is twrp-3.6.1_9-0 supported on Android 12 (LineageOS 19)?
THX

Pretty sure NO device or rom has a fully working TWRP for A12 yet. You can use it to flash roms (from OTG for example) but since TWRP can't decrypt your internal storage you can't install anything from there or make/restore a nandroid.
If you go to their website (https://twrp.me/site/update/2022/03/10/twrp-3.6.1-released.html), you can read :
"[...]
We are continuing work on Android 12. There is no ETA currently. You can follow our status on Zulip
