Yup sure does.

Another discovery, with the LGv40 and using the Korean Open rom, we would flash the OP partition from the US Open rom, thus giving us volte and vowifi, and some additional tid bits.

But, with the G8, and the a11 Kor open rom, we can't flash the a10 US Op partition, it's too big, would result in data overflow. Think the us OP was about 680 meg, the Kor OP is about 480.

Anyway, being able to xflash to the a10 US OP rom is about as good as we'll get, I'm guessing. Everything works, even twrp :) And my bet is there won't be other a11 roms (other than Kor Open), could be wrong and hope I am!

cheers
[LG G8 Guides, News, & Discussion] netmsm:
If the only problem is the size of OP partition, it could be handled. We can use US GPT files or modify KOR GPT files.

The first way is to flash rom manually using modified KOR GPT files which is a complicated task.

The second solution is to flash GPT file of LUN0 using fh_loader, after flashing the rom with LGUP.

The third one is to flash the phone using US rom, then flash KOR rom while [0]PrimaryGPT and [0]BackupGPT partitions are unchecked, like what we do for SID partitions.

I just did the first solution and it was successful. Be aware that working on GPTs may result in hard brick, so before do anything create back up.
[LG G8 Guides, News, & Discussion] AsItLies:
Yes the GPT can be mod / adjusted use from US OP, good write up to do such.

I'm hoping that there will be a US OP a11 kdz... some say that sprint phones are getting a11 now, so there's hope. If us op a11 doesn't come out, will prob do as u suggest, thnx

You can solve it, reading the comments. When u only get a few options it's because u didn't follow the original post. That UI file has to be 'read only' or it won't work properly.

Hi) every time

I try reinstall lgup, but every time this error. Please help 🥺 Stock Sprint 21f. Thanks.
[LG G8 Guides, News, & Discussion] netmsm:
There must be something missed. Try again in a meticulous fashion.

But, if it persists, then try erasing these partitions as well: vendor_a, vendor_b, system_a, system_b, product_a, product_b, boot_a and boot_b.

before erasing crate back up.

[LG G8 Guides, News, & Discussion] alej89:
I don´t have those files, I didn´t backup "modemst1, modemst2, fsg, fsc, ftm" partitions, cause I sad this tutorial from another place and noticed that step here, when I already installed the new firmware.
[LG G8 Guides, News, & Discussion] netmsm:
So, first get the phone to EDL mode and create backup of modemst1, modemst2, fsg and fsc partitions.

I need to know the current firmware on your phone.
[LG G8 Guides, News, & Discussion] alej89:
All the partitions that I didn't delete in step B), were changed when I used LGUP or are the originals?
[LG G8 Guides, News, & Discussion] alej89:
Cause the only backup I did was to the partitions you mention in B) and now to the others you told me. So, I don't have a restore for the rest. Can I do it at this point or is too late?

In case that I can backup and restore partitions, do I have to repeat step B) to get to download mode again?

The firmware I installed: V500NO30c_00_OPEN_KR_OP_1021

Sorry, but can I dm you via fb or ig, cause I borrow a laptop to do all this and I have to give it back soon and comunication here is a bit slow.

Thak you so much for respont and the help.
[LG G8 Guides, News, & Discussion] netmsm:
All partitions except those in LUN3, LUN5 and LUN6 will be changed by flashing.

Partitions in LUN5 won't change by flashing. Make backup of LUN5, it's worthwhile.

Every time you wanna do cross-flash you need to follow the whole instructions.

For download mode the phone should have its original abl, xbl and xbl_config, in case they maybe changed for unlocking bootloader.

I thought you got G8 and I asked for the firmware to provide you abl, xbl... files.

I'm sorry I don't have fb, ig, tm... account.

Extract abl, xbl and xbl_config from the KDZ you already flashed on the phone and restore them using qfil. Find a tool named KDZTool in my previous posts in this thread to extract KDZ.
[LG G8 Guides, News, & Discussion] alej89:
I ca't run kdztool, it sais that my windows version is no compatible. this laptop is running wds 10 home 32 bits version.
[LG G8 Guides, News, & Discussion] netmsm:
Are you using KDZTools.exe or the Python version?

Make a backup of abl, xbl and xbl_config then use the attached file to restore them. It maybe working for you.

If not, use KDZTool in Python to extract KDZ.
[LG G8 Guides, News, & Discussion] alej89:
i downloaded the KDZtools.exe that you upload in this thread.

you told me that you want screenshot. Of what exactly?
[LG G8 Guides, News, & Discussion] netmsm:
It's weird that KDZTools.exe does not work! So you need the Python version.

Screen shots of the phone in download mode after restoring abl, xbl...
[LG G8 Guides, News, & Discussion] alej89:
It didn't worked, it went back to fastboot mode.
[LG G8 Guides, News, & Discussion] netmsm:
When you try to get into download mode what does exactly happen? Does it show anything before fastboot screen?
[LG G8 Guides, News, & Discussion] alej89:
start the animation that appears before entering downloand mode, and immediately enter to fastboot mode.

I don't know what to do on the web that you sent me to get kdz tools in python0
[LG G8 Guides, News, & Discussion] netmsm:
The link is for KDZTools in Python you can use it to extract KDZ.

Try the attached file to restore the laf partition. Make sure you have created backup of laf partition before restoring.

Please restore abl, xbl, xbl_config and laf on both sides a and b, using the files I've uploaded and then try to get into download mode.
[LG G8 Guides, News, & Discussion] alej89:
I download the rar but I don't know how to open .py and what else to do to extract KDZ.

The first rar you uploaded only have side a, and I only restored that exact side. no b.
[LG G8 Guides, News, & Discussion] alej89:
It didn't work either. 😭😭😭
[LG G8 Guides, News, & Discussion] netmsm:
Install Python.

Read the help or readme file.

That's okay just restore them on both sides. Do not forget to create backup.

In fastboot screen if you choose download mode and press power button what will happen?
[LG G8 Guides, News, & Discussion] alej89:
It doesn't appear that option, only power off and restar.
[LG G8 Guides, News, & Discussion] netmsm:
:unsure:

Sounds like you've lost download mode!

You need to extract a KDZ and restore the necessary partitions on both sides a and b, to get into download mode.

Spoiler content hidden.
[LG G8 Guides, News, & Discussion] alej89:
oh man, my main problem has been extract KDZ. I understood and installed python, tried to open unkdz.py, a windows open but immediately close. it does that every time.
[LG G8 Guides, News, & Discussion] netmsm:
After installing Python, go to the KDZTools directory. Hold shift and right-click, in the menu you see "open command window here" click it. Go to the help file for the tool and look for the command how to extract KDZ. Put the command in the CMD window and hit the enter. That's all.
[LG G8 Guides, News, & Discussion] netmsm:
Did you just double-click on KDZTools.exe? It does not work that way! You should open a terminal window (CMD) and give it commands to extract KDZ, just like the Python version.
[LG G8 Guides, News, & Discussion] alej89:
OMG! I didn't know that. I have limited knowledge development. I want to thank you for all the patience you're having with me.
[LG G8 Guides, News, & Discussion] alej89:
Please. Can you write me down the commands I need to use? I have no idea what to write. I can count the times I've used this tool.
[LG G8 Guides, News, & Discussion] netmsm:
Put the KDZ file into the KDZTools.exe directory and open "OneKeyExtraction.bat". Follow the on screen instructions.
[LG G8 Guides, News, & Discussion] alej89:

Do you know how to get into fast boot mode after crossflashing?

I crossflashed android 11 OPEN_CA and cannot get to fastboot mode.

I tried the vol down then insert USB and also power + vol down but both don't work.

Is there another way to lock bootloader or get the Hand ID back after crossflashing?
[LG G8 Guides, News, & Discussion] netmsm:
Use the engineering bootloader files, abl, xbl and xb_config, so that you can get into fastboot mode.
[LG G8 Guides, News, & Discussion] StvOchi:
I'm kind of new at this so I don't understand what you mean.
[LG G8 Guides, News, & Discussion] netmsm:
Fastboot is disabled by default. To get into it, you need engineering abl, xbl, xbl_config or to erase FTM partition. To do the latter, create backup of FTM at first.

Create backup of abl, xbl and xdb_config then restore the attached files in place of them so that you can get into fastboot mode. Remember when you are finished with fastboot, flash the original files back.

Sir, i'm having nt-code error, no carrier services. how can I root my phone after crossflash? How can I get "cust_path_mapping.cfg"?

[LG G8 Guides, News, & Discussion] MIRAWE:
I unlocked my phone, thanks, and I rooted it, but when installing the apps, there is a problem, and when I return the original bot, it installs without problems. What is the solution?
[LG G8 Guides, News, & Discussion] mangojain:
Editing the file will not resolve the issue anyway, just use the phone with the error msg.
[LG G8 Guides, News, & Discussion] AsItLies:
@alej89

Hmmm that's not true. Editing that file is probably the best and least likely way to cause a problem.

I think the difficulty people have is knowing what to put in that file, the correct format.

So the nt-error I've gotten looks something like this:

135210,140250;FF,FF (error no customer etc etc etc)

So in cust_path_mapping, you only have to have one of those above (there are 2 in that error). And you don't want to remove what's in cust path, just add to it.

so let's say your cust path has the following:

FFFFFF,84=/OEM/OP

You would add the following (due to the individual error example above)

135210,FF=/OEM/OP

and cust path ends up looking like this:

FFFFFF,84=/OEM/OP

135210,FF=/OEM/OP

be sure when u type it in, when u put in a comma, the keyboard seems to automagically enter a space for you. Take that out, there should not be any spaces, else it won't work.

cheers

The problem isn't the message, the problem is I don't have service

[LG G8 Guides, News, & Discussion] mangojain:
My apologies for being cynical, it worked just now when I tried this -

FFFFFF, 82=product/OP

310260,FF=product/OP

This is for the Open CA installed on a TMO
[LG G8 Guides, News, & Discussion] AsItLies:
Did you ever have any service after crossflashing? I know when I tried editing the field in the SVC menu, I messed it up and lost all service. Prior to that it was working but always got the nt error.
[LG G8 Guides, News, & Discussion] mangojain:
Another question, I can always find out by trial and error but feeling lazy, for the Open CA (82) installed on an NAO_US (81), where the error msg is Check NT-Code: 0, would the solution be

FFFFFF, 82=product/OP

81,FF=product/OP
[LG G8 Guides, News, & Discussion] AsItLies:
hmmm that's a good question, not sure. If the nt-code error just shows u a '0', not much to go on.

I think the 'F' in the code is like a 'wild card'. So you could try FFFFFF,81

Or even FFFFFF,FF

I think the later is like saying any code will work. Pretty sure the format has to be 6 characters then a comma, then 2 characters (no spaces).

cheers

What's the right procedure to root my phone?

Nop, when the system loaded the first time, right after crossflashing, the message appeared with the service disable, as you can see in the 1st. image. and i try to edit nt-code in the SVC menu but it didn't allow change from there. I'm curious that ftm field is empty (I don't kow if is cause of crossflash procedure and it's normal to be that way or an anormaly of flashin' that partition)... check the 2nd image.
[LG G8 Guides, News, & Discussion] mangojain:
Ok, a few observations from trials on my 3 LG G8 phones, -

1) On the TMO with the Can Open flashed, 310260,FF works, no need for the original line either in cust_path_mapping

2) On my unlocked 810 in India, the NT code is FFFFFF,58 and having this line in cust_path_mapping works fine. If i delete the entry and reboot, i get an error msg NT Code FFFFFF,58 not found, which is logical and it goes away if i add back the line

3) Now to the issue which is not getting fixed, and the reason why i wrote earlier that editing the cust_path_mapping file doesn't help. This is my unlocked NAO_US phone with the Can Open flashed. The NT Code on the phone is FFFFFF,81 which is similar to the FFFFFF,58 on my unlocked Indian phone, but the difference is this - when i boot up the phone i don't get an error msg saying that NT Code: FFFFFF,81 is not found, instead it simply says NT Code: 0 not found

I tried FFFFFF,81 in cust_path_mapping, the most logical value, but it doesn't help.

Then i've tried FFFFFF,FF even FFFFFF, 0 to no avail.

So it seems that the NT Code: 0 not found is a much tougher nut to crack than NT Code: MCCMNC,FF or even the NT Code: FFFFFF,xx which you come across on unlocked phones.

Any ideas? Editing the NT Code in the svc menu is not allowed, and even though LGUP shows the option to change the NT Code while doing a refurbish, it actually doesn't make the change.
[LG G8 Guides, News, & Discussion] AsItLies:
No sorry, have reached my limits of understanding of this. I have the latest (A11) US Open kdz flashed and have everything working (volte, vowifi). Interestingly though, I can edit that field in SVC menu, I'm rooted with vbmeta disabled also though.

Does seem very bizarre it saying NT code of 0, doesn't make any sense.
[LG G8 Guides, News, & Discussion] mangojain:
I have everything working too, just the urge to fix the nt code error :-)

On the US OPEN vowifi didn't work, the Can Open is the best.

Could you give the steps to disable vbmeta please, maybe that would let me edit the field..
[LG G8 Guides, News, & Discussion] AsItLies:
Sure, it's relatively easy, but you need fastboot to do it.

Save off the current vbmeta image. Then use fastboot to flash it back but with these options (you can find them by doing fastboot --help).

fastboot --disable-verity --disable-verification flash vbmeta_a vbmeta_a.img

cheers
