I"m trying to figure out the best way to get back to stock pie or later with or without bl unlocked and root. lm-405uA on havoc. Thanks in advance for any help.

Well the obvious answer would be to flash a stock KDZ with lgup. The only one you wouldn't want to flash is t-mobile. Is there some reason you can't do that?

Does anybody have the oem recovery for the tmobile t817? I rooted but need to get back to stoc. Backed up everything else. If there is a better way let me know.
Maybe i should ask a different question, how do you return to stock after rooting?
You need to state which t817 you have?

t-817T for tmobile.
never mind..downloaded stock image from samsung-updates.com and then flashed with odin.
I've been searching the forum for a while, but most of the rooting guide are based on earlier version. Do i need to downgrade before rooting?

Yes you would need to downgrade, but since you have a T-Mobile version it's most likely not possible due to anti rollback

yes theres is... since hyelton already told you no downgrade.. that means no flashing 20i...
so youll be using the same procedure the same steps except flash 20i kdz.. youll will be doing all this on 20r.. so follow instructons . usiong same procedure just skip the flash 20i kdz.

sorry I haven't get on here for a while. Now my phone got updated to 20v, does the same method work? I saw your post about rooting on a 20r?

yes, same thread, just do the steps about OEM Unlocking and Root. i would grab the most recent twrp image from here (3.1.1-1) and the latest SuperSU here (2.82 TWRP Installable Zip)
you will also need adb and fastboot tools on your pc, get that here, latest version is 1.4.3
or you can just flash twrp and then flash an already rooted system image for 20v from @MicroMod777 found here

Thanks, I'll try to root it, hoping I can tweak more settings to get more battery life out of it. SOT is worst than everyone @[email protected]

Unfortunately (or fortunately) I traded it in for the s8 since I dropped it. Thought I was time to get rid of it before it loses any value. So I wasn't able to try it out...

I'm gonna try this in the morning I'm on 20v.
I recently made an insurance claim for my phone and had to send my unlocked firmware note 8 back. Problem I'm having now is, I cant get the new one on an unlocked firmware. I keep getting errors in all the Odins I have. I dont know much about the v4 bootloader or when it was locked. I was able to gi back to Nougat on my old phone and then upgrade back oreo. That was in August though. Any help would be appreciated. I cant stand this ATT ****!

You can only flash the same bootloader v4 firmwares or higher from now on. No downgrading possible to bootloader v3 or below!
Can't even go back to Nougat (that was on bootloader v3 and below)!
If you are just need the unbranded firmwares look for the ones with the bootloader v4.
Eg N950U(U1)SQS"4"CRH1. The 4 in "" is your bootloader version.
If you want to root or go back to nougat then you'll need to talk to ATT for another phone that's on bootloader v3 or below.

Could you possibly link me the the firmware I do need? I would really appreciate as I'm stuck on this current firmware. I've looked and looked. I'm just unable to find the right firmware. I suppose it's possible I'm not getting the right one. Idk.

The easiest is to use SamFirm to download the firmware. Then use modified ODIN 3.13.1 to flash it.

I figured all out! I managed fo flash the latest unlocked without any issues.
I've been trying to figure out if it's possible to Re-Lock the Bootloader on a stock rom and bootloader for a sprint unlocked phone running Android 8. I couldn't find anything in the forums. Anyone have an idea?

If you can get a hold of your v40's stock KDZ and do a refurbish flash of that KDZ in LGUP with the correct DLL's applied to LGUP's common folder so it reads your phone as connected it should wipe any modifications and reflash the stock locked bootloader. But of course will also wipe ur rom and user data. The guides on how to do this are here in the forum.

Gotcha, thanks for the info. I think that's where I'm at, I'm unable to find a KDZ for sprint.

Mainly because Sprint hasn't leaked any of their KDZ...
Edit: I flashed to US Cellular not US Unlocked.
Currently flashed:
v405UA020g_00_USC_UYS_OP_0424.kdz
Is there an alternative place I can find Sprint kdz, downgrade to US unlocked or some way to restore LTE service.
As far as I can tell I might be able to root and then flash a custom firmware using TWRP and then downgrade onto US Unlocked.
Can anyone confirm that is the correct course of action?
Why make it hard?
Just flash the US unlocked version via LGUP.
That works with Sprint well.
And no, there is no Sprint KDZ available.

Thank you so much for your reply.
When I try and flash the us unlocked via refurbish or upgrade I keep getting an anti-rollback error, something like USCELL>Unlocked or something like that.
Got frustrated in the middle of typing that and tried botching a refurb by unplugging in the middle and was able to get US unlocked on there afterwards.
