What I did - having already access to DL mode, I went back to EDL, replaced all files in exactly the same order as in the tutorial below with IMG files, which I extracted from my KDZ file (same which was in my phone when it bricked - link to instruction and files to extracting KDZ - previous page in this topic):

luetaj said:

- find select and right click on "xbl_a" then manage partition data and select load then select "xbl.elf_6"

- find select and right click on "xbl_config_a" then manage partition data and select load then select "xbl_config.ebl_902"

- find select and right click on "xbl_b" then manage partition data and select load then select "xbl.elf_6"

- find select and right click on "xbl_config_b" then manage partition data and select load then select "xbl_config.ebl_902"

- find select and right click on "tz_z" then manage partition data and select load then select "tz.mbn_134"

- find select and right click on "hyp_z" then manage partition data and select load then select "hyp.mbn_646"

- find select and right click on "boot_a" then manage partition data and select load then select "boot.img_163830"

- find select and right click on "cmnlib_a" then manage partition data and select load then select "cmnlib.mbn_81670"

- find select and right click on "cmnlib64_a" then manage partition data and select load then select "cmnlib64.mbn_81798"

- find select and right click on "boot_b" then manage partition data and select load then select "boot.img_163830"

- find select and right click on "cmnlib_b" then manage partition data and select load then select "cmnlib.mbn_81670"

- find select and right click on "cmnlib64_b" then manage partition data and select load then select "cmnlib64.mbn_81798"

- find select and right click on "abl_a" then manage partition data and select load then select "V35abl.img"

- find select and right click on "abl_b" then manage partition data and select load then select "V35abl.img"

- find select and right click on "raw_Resources_a" then manage partition data and select load then select "raw_resources.img_194918"

- find select and right click on "tz_b" then manage partition data and select load then select "tz.mbn_134"

- find select and right click on "hyp_b" then manage partition data and select load then select "hyp.mbn_646"

- find select and right click on "laf_a" then manage partition data and select load then select "laf.img_81990"

- find select and right click on "laf_b" then manage partition data and select load then select "laf.img_81990"

In my opinion it should be tz_a instead tz_z and hyp_a instead hyp_z - so I used A files (in image from V500N there is no Z files)

Again entered LGUP and start in Dpartition DL mode with SID A and SID B unmarked .

Simple - right? :)

I'm so happy...

[LG G8 Guides, News, & Discussion] figer:
Okay. I have cooled down a bit after the recent events with my phone, and am ready to continue the story.

Since after replacing the files from my post above - LGUP recognized my phone as G8X, and then back after replacing them with the correct one recognized it as V500N - maybe if you unpack KDZ from the EM version, for example Hungary - V500EM30b_00_OPEN_EEA_OP_1025.kdz

and replace these files in QFIL with those unpacked - maybe LGUP would allow without rooting the phone to the swap of the European software?

But all in all - your netmsm method is easier as it just deletes a few files ...
[LG G8 Guides, News, & Discussion] figer:
Unpack the rom exactly the one you had on the phone before the changes - the link to the tool gave netmsm - 2 pages earlier and replace the files in QFIL with the unpacked ISO files in the order I gave quoting luetaj on the previous page. If you have a backup of your files - you have to be sure that these are your files from before the accident (when the phone was still working), then you can use your files. Certainly you need to have a backap of the files that netmsm specified 2 pages earlier so you don't lose your IMEI etc.

After these changes, try LGUP in Partition DL setting with SID A and SID B unchecked.

Maybe it will work ... It worked for me.
[LG G8 Guides, News, & Discussion] artyom1603:
thanks, all worked well
[LG G8 Guides, News, & Discussion] figer:
Thanks netmsm again!

Without your advice and the backup I made on your advice, I would be dead.

Without the IMEI code, you can no longer fumble with your phone with QPSTConfig.

I was taking apart the phone again, because he didn't even want to enter the EDL and only by shorting the points on the PCB I was able to restore the files from LUN5 and the phone works again

btw, i successfully crossflashed,after many attempts and everyone who is having issues,make sure you follow guide closely and only use drivers and apps listen in tutorial cuz they are modified. (dont forget to backup everthing,that saved my phone)

everything works fine, just one question: is Hand ID supposed to break after crossflash?

Two things for now: 1. remove any space in the path and name of the firehose file. 2. you need to be quick to open partition manager so it's better to have qfil ready then bringing the phone into edl mode and quickly open partition manager.

Thanks for this guide, it was easy to follow and I had no issues with switching my Sprint phone to Open_CA Android 10!

However I noticed that there is a new Open_CA KDZ for Android 11 that was just released. I was wondering, do I still need to follow these instructions again to update my phone from Open_CA A10 to Open_CA A11, or can I just go ahead and flash the new KDZ with LGUP now that it has already been crossflashed? Sorry if this is a stupid question.

Hello! I followed the steps and it worked. My LG G8X from Sprint is now in A11. I installed a kdz from Germany and, apart from the NT pop up when restarting, everything seems to be fine. I can do calls and data has no problems. However, my SN is missing. I read the entire thread and saw that restoring the original FTM partition is a fix for that.

I didn't see any steps, and I'm sorry if I just didn't read correctly, but I have some questions:

By restoring you mean going into QFIL > Partition manager and selecting my current FTM partition, select "Load Image" and loading my original FTM backup in BIN format? Or do I have to do it in another way?

Will my phone be reset and have to do the setup process again?

Thanks in advance and extra thanks, @netmsm for this amazing tutorial.

[LG G8 Guides, News, & Discussion] Nemo Draksler:
Thanks for your quick response, @netmsm. I restored the original FTM partition and my SN is back! It did not wipe anything, but it removed my custom settings for my stock launcher and the bloatware apps I had uninstalled appeared again, but that's easy to fix.

I'm glad I took the decision to do this and finally update. One of the things that bothered me with this phone was the inability to share a QR code for the wifi directly from the settings, as can be done in many other phones. Well, A11 didn't bring the feature, but it made possible for me to install the LG wifi settings apk (from the LG Velvet, I think) and get the function!

One thing I found, and another person mentioned same in tele group, I went from Sprint a10 to us open a10, worked fine. But after using magisk and flashing twrp-inject-a-b zip, can't get it to go into recovery.

Didn't think to try to get to recovery prior to flashing twrp, but no matters what button combo used, it won't go to recovery.

didn't try 'adb reboot recovery' because with this version of twrp, if u don't use button combo to get to it, touch screen don't work.

odd problem really.

Hey good for you, so the Open a11 must be the Kor version right? Either way, could u do a big favor and try to get to recovery? Of course don't erase anything, but just verify you can get to the recovery screen?

thnx!
[LG G8 Guides, News, & Discussion] AsItLies:
So, we just got this sorted. Thanks to SGMarkus as he mentioned it's the ftm partition that controls recovery access and fastboot access. So, with the newly flashed kdz, as it is, you can't even get to fasboot although u flashed the eng abl to it.

But! Restore your old ftm, after flashing, and then you'll get access to both recovery and ability to get to fastboot after flashing eng abl.

cheers!
[LG G8 Guides, News, & Discussion] AsItLies:
Another new and unfortunate development. If you're rooted and want twrp, doesn't look as though the twrp version we have is gonna work on a11. Just tried that with the install-twrp-a+b zip and it installs, u can get to twrp, but u can't mount any partitions. Thus, u can't format data.

we do have root, but twrp looks to be a problem.
