Do you happen to know what partition what partition controls fastboot mode. I can 9008 that one out of my second v60 and then load it into the first on?
[LG V60 ThinQ Guides, News, & Discussion] deathglass:
Anyone know how to fix this error? Trying to crossflash tmobile onto ATT

*I think the issue was the USB cable; switched from USB C to normal USB... Maybe useful to add that to guide.
[LG V60 ThinQ Guides, News, & Discussion] Karol75:
It happened to me too.

I just went back in edl, deleted ftm, modem_a,b,...etc ,back in to LGUP,on 4th attempt,it worked.

Battery estimated time remaining don't seem to be working /showing on crossflashed kdz, does anyone else have this issue?
[LG V60 ThinQ Guides, News, & Discussion] Ahmad alsayad:
Question: did you used the phone for a while, 1 or 2 days ?
[LG V60 ThinQ Guides, News, & Discussion] Karol75:
Yes I did, probably not more than 2 days as I wanted to experiment and flash all KDZ's available for the V60. Last time I flashed yesterday morning. Charged it last night. This morning,still not showing.

How do I find the /data/local/tmp directory and copy the systemrw folder there?
[LG V60 ThinQ Guides, News, & Discussion] Ahmad alsayad:
You should more, more, more of heavy use it ...also install an app accubattery just so you know if there problem after crossflashed kdz ...

Unlock + root working on LV600TM. Only minor problem I ran into was the following error in QFIL:

Just needed to run the version of QFIL bundled with QPST and everything's working. Thanks for the guide!

Thank you @JigsawMobile and @crimsonrommer, i was able to cross flash my V60 and update it to Android 11 with root! Today is a good day!
[LG V60 ThinQ Guides, News, & Discussion] Karol75:
Ok, so can anyone confirm that the root is a success on a V60 device?

Since there isn't any custom recovery for this phone,what exactly is achieved by unlocking bootloader and rooting?

If I would root this I'd like to be able to use banking apps, Gpay etc and permanently gain high impedance mode since I'm using Beats headphones and the only way I can trick the quad DAC is by using an extender and plug in a 64 ohm earbud first.
[LG V60 ThinQ Guides, News, & Discussion] deathglass:
I am on rooted T mobile android 10, what option in download mode do I use to upgrade to android 11 with lgupdate tool? (no OTA update it looks like). If I do it this way, will it erase data, or would I need to re-root?
[LG V60 ThinQ Guides, News, & Discussion] JigsawMobile:
Yes, you can use banking applications, but root itself does not mean that you will be able to modify system files without disabling the RCT service. I don't have the ability to modify system files at the moment, which means I can't remove system applications, but it doesn't pain if you have root.
[LG V60 ThinQ Guides, News, & Discussion] Karol75:
Thanks for the explanation. I rooted again yesterday,tried to modify the XML file in vendor/etc for the quad DAC, but couldn't and I didn't know why.

Anyone able to fix the fingerprint once rooted? I tried the whole service menu->fingerprint test->fail (can't pass it) many times and it didn't work on this phone (N to EA flashed). On my other phone, the first step passes but fails but it eventually got it working. On this one, first test always fails and it doesn't fix the fingerprint.

Edit:

Anyway, ended up fixing it by upgrading to Android 11, fixing the fingerprint there and then downgrading to Android 10. Doing that, the fingerprint is still fixed.
[LG V60 ThinQ Guides, News, & Discussion] Unessential:
I probably should have asked this before... But, which partition is my original firmware? I can find kdz files online for all variants except for AM. If i want to restore my original AM firmware... I'm guessing leronex's instructions had the foresight to back up the partition including the firmware?

How would I restore it?

edit: I wussed out and didn't crossflash yet and restored the erased partitions ... Until I get an answer to this post. ... JUUUUST in case... -- because I want to make sure i have a way to restore AM after crossflashing incase **** goes wrong...

Sometimes simple things get overlooked.

Have you tried turning on System R/W in your choice of file explorer? I've been out of the phone modding scene for a while and forgot all about that.
[LG V60 ThinQ Guides, News, & Discussion] Karol75:
Yes done that . Changed it to RW
[LG V60 ThinQ Guides, News, & Discussion] Karol75:
You can ask Leronex to backup your original firmware with Medusa, than you can cross flash, I've done that, happy with the EA ROM. Wouldn't go back to AM.

Unlocked ATT. Was fallowing the steps, but when at LGUP, I get the "Error: 0x6004, CrossDL NA1_US>NA3_US Target_product changed." - no matter which kzd (EA, TM, VM) I try to use. Phone does not start - I get iinto boot loop with message that the device has failed a routine safety check and may not work properly.

Any ideas 1) what has failed? and b) how to unbrick the phone?
[LG V60 ThinQ Guides, News, & Discussion] Karol75:
This was my V60 last week same issue.,what I've done is went back again in edl, done everything from scratch ( delete ftm, sid_a sid_b etc) then boot into download and eventually it worked on 4th attempt..
[LG V60 ThinQ Guides, News, & Discussion] sheshtas:
How did you get beck to edl? In my case, phone only bootloops with security failure issue - or, if connected via usb, allows to enter the download mode. Did not manage to get into edl, no matter what I've tried..
[LG V60 ThinQ Guides, News, & Discussion] Karol75:
Just hold volume down and power whilst phone connected to the PC,as soon as you hear it disconnect,rock the volume up button in quick succession. Don't worry if it fails once. Give it several tries , It will boot in edl eventually
[LG V60 ThinQ Guides, News, & Discussion] sheshtas:
Thank you! Played some time with it, but finally managed to get into EDL (had to power off the phone from download mode first). Will try to recover the phone in the evening :)
[LG V60 ThinQ Guides, News, & Discussion] Karol75:
Yes and don't forget ,do not let the phone to boot after you finished with edl. Hold volume down and power unit you hear the phone disconnects,as soon as it does , let go of them and press and hold volume up to go straight to downloaded mode .
[LG V60 ThinQ Guides, News, & Discussion] andamiro00:
Please understand if the sentence is awkward because it was written using a translator.

Thank you for telling me how to unlock the bootloader of the LG v60 device. There was an error during cross-flashing, so I'm asking this question.

I tried cross flash. An error occurred as shown in the picture. Unlike other lgv60, my v60 doesn't have several partitions.

"operatorlogging" ,"eri", "carrier", "persdata""OP_a" ,"OP_b"

My v60 seems to be an error caused by a lack of partitions, but did you solve such an error?
[LG V60 ThinQ Guides, News, & Discussion] FC06:
Has the att issue when crossflashing been fixed? (the one where you cant choose network operators, APNs and such)

I have a qfil problem, just wondering if anyone has seen this error before.

Download Fail:FireHose Fail:FHLoader Fail:The system cannot find the file specified

This error comes after everything has been setup correctly. I point it to the firehose listed on 1st post. I've used all of this dozens of times but somehow now all of a sudden I'm getting the error above???

Problem solve. For future reference QFIL must run from Qpst which is to say: Use the QFIL under the Qpst entry of windows programs.

I completed this guide and my T-mobile V60 is rooted but I have one issue, The WIFI does not turn on, just cellular data works. Any idea what the issue is?
[LG V60 ThinQ Guides, News, & Discussion] garyyo:
Yeah, I had the exact same problem. You likely messed up the rooting step because you were on the wrong A/B partition when you extracted and patched you boot image. You were likely on the B partition and used your boot_a.img. The correct way to solve it is to have had a backup of your boot_b.img but if you followed the guide exactly you overwrote that. With that backup you can just patch that with magisk and use it instead of the boot_a.img.

The way I solved it is to relock your bootloader, restore all of your backups (your backed up boot_a.img, abl_a, and abl_b) then update your phone to get back to good B partition (assuming you did an OTA update before, if not you should still be rolled back one update). Then redo all of the steps of flashing the engineering bootloader (which partition you are on doesn't matter for this one), then apply root but to the correct partition (it will say which one you are in when in fastboot mode) instead of just applying it to A/B.

This does mean you have to do a factory wipe of the phone though. I am also not sure if this is the best way to accomplish this, but it worked for me. Might want to read up on A/B partitioning and related topics as not understanding them is what led me to making this mistake in the first place.

Would I be able to crossflash my AT&T V60 that's on the latest version of A11? I feel like changing it into an EA version instead to remove bloat and fix the fingerprint bug, but the tutorials I've read here are suggesting to be on first A11 version or last A10 version iirc.

I figured out how to get rid off the NT code error on my cross-flashed AT&T variant (IMPL value is 1, locked) with modifying the ftm partition, However, after changing it, mobile data stopped working (tried setting the APN for my courier but without luck) and the NT Code in the MID information of the hidden menu instill show the same old value

The good side is that

* in Mobile networks settings, APN and network operator can be set now

* the NT code error is gone

* a bunch of new apps appear in the app drawer

* in Update center settings, there is a new item "Software Update" (not sure if this really works because my phone already on the latest version)

* weather wedge is available

Any ideas to fix the mobile data issue??

This is how I did it:

1. back up the ftm partition with QFIL in case something goes wrong

2. edit a copy of the backed up ftm file with hex editor (I used HxD)

3. at the offset 00014000 update your NT code and save (use the right-click command "Past write" so that the file size will not be altered)

Notes: My AT&T v60 had been cross-flashed to the EU version, the value at this offset is all zeros for some reason (previously was a long NT code begins with "15","310,410...

4. flash the modified ftm back and exist 9008 mode

reference:

Getting access to recovery combination(FTM mod)

* I'm not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed (like it did for me...). * YOU are choosing to make these modifications, and if you point the finger at me for messing...

There isn't any fix for this, as far as i know....I tried edited ftm.bin myself and like you,no data after the first reboot.

I learned to live with the NT-code error, everything else works great.

By the way, if you flash T-Mobile KDZ , APN settings will be available .

But NT-code is still there.
[LG V60 ThinQ Guides, News, & Discussion] jdlfjk:
I was downloading the TMobile's KDZ give it a try but then I stupidly deleted some essential partitions in QFIL so now the phone is bricked.. Stuck in edl mode and also stuck when opening the partitions manager again. I do have backups of the deleted partitions. Any idea if it can be fixed? Thanks
[LG V60 ThinQ Guides, News, & Discussion] Karol75:
Can you not load back the backup files with QFIL ?

Also, does the phone still go in download mode ?
[LG V60 ThinQ Guides, News, & Discussion] Jaimesco12:
so do we make a magisk image for both boot_a and boot_b? You only put boot_a in the directions so just double checking. I only have the magiskpatchedboot.img for boot_a at the end, confused where you got the boot_b one.
[LG V60 ThinQ Guides, News, & Discussion] Greg Polar:
I understood "do fastboot flash boot_a and then fastboot flash boot_b" as "do both of them". I Did that and I really am golden :), so doing both a and b seems to be the right way. I have V60 ATT version preparing to crossflash to TMO.
[LG V60 ThinQ Guides, News, & Discussion] JigsawMobile:

did you flash super.bin OP_a/b?
[LG V60 ThinQ Guides, News, & Discussion] jdlfjk:
I didn't flash super or op_a/b in QFIL to unbrick the phone, only in download mode, I used LGUP to cross-flash the KDZ with all partitions except sid_a/b and abl_a/b just like documented in this thread.
[LG V60 ThinQ Guides, News, & Discussion] blaze2051:
so you went from ATT to Tmobile?
[LG V60 ThinQ Guides, News, & Discussion] jdlfjk:
No, I decided to go from ATT to this V600EA20k_00_1112.kdz because I know with this one mobile data works out-of-the-box.
[LG V60 ThinQ Guides, News, & Discussion] Karol75:
Because I'm not rooted, neither bootloader unlock, when I cross flash, I only deselect sid_a and sid_b in LG up.
[LG V60 ThinQ Guides, News, & Discussion] blaze2051:
Do you know what partition needs to be flashed to install a GSI rom on the Tmobile V60 variant ?
[LG V60 ThinQ Guides, News, & Discussion] blaze2051:
was that the only benefit using that international firmware?
[LG V60 ThinQ Guides, News, & Discussion] jdlfjk:
Well, it has less bloatware apps and they can be uninstalled (fackbook, booking.com etc) and since I don't live in the US so I don't see there is any good reason to flash a tmobile or verizon FW.

Also by loading the mbn file through PCM , radio/signal is behaving as it should in Europe.

My phone stays on 4G LTE now, before it always switched between 3g and 3g+ , rarely had 4G. Had to use LTE only in phone info for constant LTE signal.

Curious if 5G works, will see next weekend, traveling to Bournemouth ,there is coverage.

[LG V60 ThinQ Guides, News, & Discussion] Karol75:
You need to extract it from your desired KDZ you are about to cross flash the mbn file is in modem_a / b partition, to load the mbn you have to download and install Qualcomm drivers and qpst tools, then load it with PDC tools
[LG V60 ThinQ Guides, News, & Discussion] Greg Polar:
There is one more thing I was hoping to fix with crossflashing and rooting - my ATT version is not able to receive calls (straight to the voice mail). I get them only from time to time and really rarely. Do you have any ideas or any dependencies I don't know about? After crossflashing to EA it is the same (cannot setup my bank app because the activation code is provided by IVR call)
[LG V60 ThinQ Guides, News, & Discussion] Karol75:
I can't tell you if these issues would be fixed after cross flash , i never had problems recieving calls or setting up bank apps/Gpay on the official ATT firmware.

My only issue was that phone didn't have constant 4G signal, was always switching between 3G /3G+,even after cross flash.

But wit these recent modifications,thanks to jdlfjk (edit ftm.bin/mbn load) I can say phone works better signal wise. I do have constantly 4G LTE now, probably same as on a phone that's made for EU market .

I'm not rooted , I probably never will root as I do want to use bank apps and Gpay.

Plus, there isn't anything in the rooting I'm excited for .
[LG V60 ThinQ Guides, News, & Discussion] Greg Polar:
After couple of experiments, I assume that my issue is connected to voice connections over LTE. When I use the hidden menu to set "RAT Selection" option to "GSM / WCDMA" only, I can receive calls. When I'm in "GSM / WCDMA / LTE auto" mode, I have a stable LTE data connection but can't receive calls. As if it took too long for my device to switch to GSM.
[LG V60 ThinQ Guides, News, & Discussion] Karol75:
Ok, you can also use any apps on Google play called" 4g only". I used to have those to switch between 4g only and wcdma .On 4g only couldn't recieve/make calls as no VoLTE.
[LG V60 ThinQ Guides, News, & Discussion] KouaV1:
Thats possible, there was an unfinished twrp released for the V60 but fgot what website but best be advised to wait for a finished tested twrp.

For now root has benefits with using magisk modules such as SOC updates, sound fx, etc. Root also does stop the phone from being forced ota updated which is usefull for users who want to keep the current software/android version. In my opinion custom roms are not worth it for an daily or average user unless you want to maximize performance of your phone. Even that I would root on LG stock android 10 and just stay there for an out of the box performance.
[LG V60 ThinQ Guides, News, & Discussion] KouaV1:
You need to flash the boot images back, in theory just reverse back the methods. Flash backed up abl_a to abl_a and abl_b to abl_b.
