[Q] Looking for "Custom DLL" (for flashing *.TOT) which Bypasses Cross Firmware Check

[Q] Looking for "Custom DLL" (for flashing *.TOT) which Bypasses Cross Firmware Check
Hi I would like to return to stock on my soft bricked unlocked LG G Flex D959 T-mobile (details in my other thread http://forum.xda-developers.com/lg-g-flex/help/soft-brick-custom-recovery-logs-t2919608)
I see for the LG G2 there is a custom DLL that bypasses the check when flashing. I want to flash the wrong version for my unlocked LG G Flex D959 T-Mobile.
This DLL for G2 was referenced http://forum.xda-developers.com/showthread.php?t=2695855 and http://forum.xda-developers.com/showthread.php?t=2432476. .
"YOU MAY NEED TO USE THE CUSTOM DLL FILE BELOW FOR WHEN/IF YOU USE TOT FILE TO RETURN TO STOCK!!! The reason for this is because some D80220a references needed to stay in build.prop and LG Flash will not flash D800 firmware on device when it thinks it is D802. After you return to stock using TOT method you can use the regular DLL file or keep using the custom DLL file. The download for it can be found in the download section below."
Is it possible for me to flash using this DLL for the G2? If not where can I find an equivalent DLL for the G Flex?
Running out of options!
Thanks,

I was Looking for it also...
Changed My F340K into D955. I tried with both DLLs but both failed

I don't believe so. And what are you meaning by "unlocked" I've seen several peep lately say they are "unlocked"
Correct me if I'm wrong but the only flex variant who's bootloader can be unlocked is the F340. The D959 has not been able to be bootloader unlocked yet. I don't think the AT&T, Verizon, or Sprint variants have been either. So what do you mean by "unlocked"

I have edited my bulid.prop.. and forgot to change permissions.. now my phone after LG goes to blank screen with front Green LED blinking..
I succesfully pushed the backup file from my pc.. but I am unable to fix permissions..

Can you get into custom recovery or download mode.

I am waiting for Official Lollipop update So i dont have custom recovery..
When I volume Up and Power in my F340K G Flex on Stock Rooted 4.4.2 V20D it will go to a LG Service menu with Korean Written..
in this Menu ADB shows the device as Recovery And I am Once able to Push My backup Build.prop...
When I Volume Down + Power It goes to reovery but It only shows an Android icon with Red Triangle on It..
Look my Build.prop file and its back with Right Permissions..
When I adb Fix permissions. It returned that Operation not permitted or Permissions denied.
Yes I can go to Download Mode... Korean written in it

If you can get to download mode then PC Suite or LG Flash Tool should work to refresh KK 4.4.2 on it for ya. And you can put custom recovery on there and root and such. Just flash back to stock when the OTA comes out. Its liable to be 3 months or so if I had a guess

If Connect my phone in download mode to "LG mobile support mode" and upgrade recovery option it says that no upgrade needed,
and if I connect My phone in black screen mode, It keep saying that mobile isnt connected during the os/ Phone check..
downloading PC Suite..
any further help?

So you're on the wrong variant software ?
Sorry I'm just trying to understand what is exactly going on. Does it boot into any OS ?

PC Suite also says that no need to update in All 4 modes..
1. LG service Mode (adb recognizes it as Recovery mode)
2. Black screen mode
3.Recovery mode (Android Laying with Red Exclamation Mark) All Korean Mobiles have this instead of Recovery, Dont know why.
4. Download Mode
Yes, I have changed My Product Model from F340K to D955 and add remove some line realted to Telephony..
AS I have pushed my backup file back (some luck) and read it with the command "less build.prop" in system directory and also pulled it and see contents. its ok now..
The only Issue remains is Of Root Ownership and 644 permissions as you can see in the picture, (as For My knowledge)

You don't update. Go the top menu bar and click on "mobile devices" then "restore upgrade errors" while in download mode. It will not flash back in android versions but it will flash the same version or newer if there is newer. It may not recognize your device and that may be a good thing cuz then it will ask for your model # and serial number so it knows what software to flash. Takes a bit to download the .kdz but only about 5 mins to flash once it's downloaded.

As I told You that I somehow managed to push my Backup Build.prop file to system..
This time Tot File worked... LG flash Tool 2014 didnt worked for me. im all three configurations...
Restored 10C... Now updating again again OTA... To V20D...

Downgrading troubles ZVA->ZV6

Hey guys,
First off, i thought I had already posted this question but I can not even find it in my ousting of posts. So I want to apologize I advance of this ends up as a duplicate.
I currently have a Sprint LG4 that upgraded to ZVA and I lost hotspot. Trying any method to downgrade, fails. Using LGUP fails with "SPC code does not match." and LG Flash Tool says error at DoDownload and nothing other than a code, 00000064. I have also tried the method using systemZV6.img and dd via SendCommand but nothing happens at all with that one after i press Enter and wait a few his.
I have tried various USB ports and all drivers I could find on these forums. Windows 7. Any other info I can provide to help you help me? I am no stranger to flashing other phones, but having no luck here. Searching the web hasn't turned up any help. Thanks in advance.

Is the phone bricked now? You can't downgrade from ZVA to ZV6, because the qfuse version is different.

Thanks apparently i missed that one somewhere as a search via duck duck go never gave turned up results that stated so. In fact the last posts of http://forum.xda-developers.com/sprint-g4/general/how-to-free-mobile-hotspot-root-t3165049/page16 led me to believe it was possible.
Fortunately it is not bricked. Thanks for your reply.

Since it is not bricked, you could probably fix it by flashing the ZV9 update. I don't think there is a tot for ZVA yet, so you might possibly have to wait until there is one available.

if mine is ZVA, can I use the path ZVA -> ZV9 -> ZV6 to downgrade to ZV6? I mean using LGUP.

I don't think you can even use ZV9. I know I said you probably could, but I forgot that's the whole reason you're here; because the qfuse version is different. You will have to wait until a ZVA TOT is available.
I could be wrong, but I'm not a dev. At least be thankful your phone isn't completely bricked.

I just downgrade from ZVA to ZV6 using LGUP. Just the first boot take more time than usual but I did factory reset and everything fine.

qfuse is not different. It should work fine.

Can you give more detail? I have used the TOT and instructions from http://forum.xda-developers.com/sprint-g4/development/restore-sprint-lg-ls991-zv6-tot-t3213196 and always get an SPC does not match error.

Having issues as well. ZVA>ZV6. When I dl the tot file and run it in LG up it says it's not a valid tot file. Also tried the LG flash tool method and get an error message. Any help?

Hope this help you

Anyone try to update back to ZVA after root?

Once rooted you can't use the OTA updates because they will fail. They check for that kind of crap. Sucks, but you're stuck on ZV6 with root until the devs work out a bootloader unlock, which may take some serious time. LG sucks major donkey balls because they have some pretty secure bootloaders, now. The best thing you can do is stick with ZV6 at the moment. I know, I know, security patches! Marshmallow! Still, wait until they get something worked out.

Thanks, i figured. Only reason i ask is because im having an issue with mircast. Not sure if its because im on ZV6 or because im on UltraPop..

So we downgrade zva to zv6 or not
Can anyone successfully downgraded to zv6 if YeS so how

DoDownload Error when flashing TOT

I have a friend with a bricked LG G4. It's a sprint model LS991. He has no idea what firmware he is on and so far I've tried ZVB ZV9 and ZV6. Every time it gets to about 10% and gives me "DoDownload Error!!!". I have been searching for hours and have found many people posting with the same problem but they seem to be ignored in most threads. Has anyone had this issue before and found a work around? Or can anyone at least tell me what it means? It seems to occur after this line:
CheckDL Validation
_prepareAfterDload download
00000064
DoDownload Error!!!
I have tried different DLL files (generic and model specific) as well as on Upgrade + DL and Board DL with no change. Any help would be greatly appreciated.

Re-Lock Stock Bootloader on Sprint Oreo?

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.

Flashed V40UA to US Open. Can I go Back? No LTE.

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.
