SIM cards can only be unlocked from the device unlock app. OEM unlock if for unlocking the ability to run the fastboot command 'fastboot OEM unlock' which in turn unlocks the bootloader.

[MENTION=5000933]have0[/MENTION] reboot and try again. Enabling the OEM unlock option worked the first time for me on my last 3 different LG devices, so unfortunately the only other idea I have is that if your bootloader is truly still locked then turn off developer options and then turn them back on, then try the OEM unlock switch again. Also this recovery version is depreciated and has the efs backup bug from its twrp source. I suggest this version as it is the closest to having the correct time/date when you perform backups.

You are correct. I stand corrected. Thanks.
[T-Mobile LG V10 Android Development] linsalata28:
Can someone please help me? I have the bootloader unlocked. When I try running the command in the OP to flash the recovery it says "I'm not looking at it now so it's not exactly what it said"

It says it's flashing the recovery finished then something else.. Can't remember but the last part says error flashing recovery.img command not found.

I'll go on later and get the exact error.

What I really wanted to know was where am I to put the recovery.img ? I put it in the same folder where I have adb and fastboot and then I tried putting it on the root of the internal memory on the phone.

Thanked for any replies.

Can I flash this TWRP to Android Nougat H90130b stock rom? I have unlocked bootloader.
[T-Mobile LG V10 Android Development] mr arrieta:
same question as scytalemk, my tmobile v10 is bootloader unlocked, will this twrp 3.0.0 work?
[T-Mobile LG V10 Android Development] mr arrieta:
I tried to run this twrp on my tmobile LG V10 (h901) unlocked bootloader but it doesnt seem to work, i did "fastboot boot twrp.img" but got "FAILED (remote: unknown command)", i dont know if should do a flash, my phone was on Marshmallow and i updated it via LG Bridge to Nougat.

Anyone?

[T-Mobile LG V10 Android Development] jmatic:
Same problem here. I did a manual update with update.zip to nougat and I had twrp with root which were not affected with the update. But then I decided I want a clean install. I installed .kdz update to nougat with LGUP for a clean install and I regret it now because I can't install twrp anymore and shows me the same error as yours. I do not believe twrp.img is the problem because I tried other .img files and nothing does flash and gives me the same error.

Anyone have any suggestion on how to rollback or better yet, to fix this error? Tried everything on the internet and seems like lots of people have this problem but nothing definitive that works. Thanks

Working on nougat?
[T-Mobile LG V10 Android Development] dj_m:
so fastboot commands are locked in the phone for those who have nougat

i tried just for fun to see if i can retrigger fastboot commands with fastboot flashing lock and unlock and adding critical also but no luck i get unknown remote command error

Can anybody help me with that?
[T-Mobile LG V10 Android Development] rizkhan999:
Dear abenmila!

Have you tested it yourself on Nougat with unlocked BL?

Because many users including me are getting the error of FAILED (unknown command) when execute fastboot boot and fastboot flash commands after unlocking the bootloader.
[T-Mobile LG V10 Android Development] NestorRamUre:
Now i have another problem... accidentally updated to 30B :(

Now i need to downgrade to 20e or some MM kdz.
[T-Mobile LG V10 Android Development] rizkhan999:
You cannot downgrade to 20e because its on anti rollback v1 while 30b on 2. However you should be able to downgrade to 20j and 20l since both are also on anti rollback v2.

Check and give your feedback. I would be waiting for that.
[T-Mobile LG V10 Android Development] rizkhan999:
Also flash using uppercut if lgup fails.
[T-Mobile LG V10 Android Development] NestorRamUre:
ERROR: 0x2BC, Invalid command response code = 0x80000202 :(

It was trying to downgrade to 20J...

Now i'm downloadig 20L and try with it too, my last chance to downgrade :(
[T-Mobile LG V10 Android Development] rizkhan999:
At which % and at which partition did you get this?
[T-Mobile LG V10 Android Development] NestorRamUre:
14%, 20L and 20J :(

Do you know why this is happening?
[T-Mobile LG V10 Android Development] rizkhan999:
Mine failed at 23% during system partition with the same error as yours. Wanted to verify if it is specific to me or also happening with others. Seems like LG has incorporated some limitation other than ARB version.

On one hand they manufacture such faulty devices and on the other hand lock them up in a way that no one may be able to overcome THEIR hardware faults using software :mad:
[T-Mobile LG V10 Android Development] NestorRamUre:
You tried using LG Flash Tool and not LGUP?

I've been thinking in that but i don't know.

Can you try with LG Flash Tool and tell me if it worked for you?
[T-Mobile LG V10 Android Development] rizkhan999:
No I tried with LGUP. Not with LG Flash Tool. My device was already in bootloop. Now it goes off before booting into the Download Mode. So can't flash anymore. You should go ahead and flash with LG Flash Tool and share your results.:good: Would be anxious to know.
[T-Mobile LG V10 Android Development] NestorRamUre:
Good, today I've been working too hard and I'm tired but tomorrow I'll download LGFT and try, I'll share my experience with all of you guys.
[T-Mobile LG V10 Android Development] rizkhan999:
If LGFT also doesn't work, you can try SALT (teadfasterX [A]ll-in-one [L]G [T]ool). This tool forces the flashing of one firmware over another regardless of any warnings whatsoever. So there are high chances of bricking your phone using SALT wherever LGUP would refuse to flash and thus save your phone from a possible brick. So unless you have tested QFIL files for H901 available, it is not recommended to try this on your working phone using SALT.

This genious tool by steadfasterX looks like this (see attachment).;)
[T-Mobile LG V10 Android Development] rizkhan999:
Also check the model written on your board. Is it H901 or else? Like I have VS990 board while H901 software.
[T-Mobile LG V10 Android Development] NestorRamUre:
Mine too :confused:

I have H901 software on a VS990!

And now... WHAT CAN WE DO?!
[T-Mobile LG V10 Android Development] NestorRamUre:
Can you explain me step by step how can i do it?

I'm completely a novice hehe
[T-Mobile LG V10 Android Development] rizkhan999:
Don't worry. You still have hope. Unlock LGUP developer features as done here. You can see its 3rd and 6th posts for alternate ways of doing it. Then, if you have already unlocked your bootloader, rename the twrp image of this thread as recovery.img and flash it to your phone using PARTITION DL option of LGUP, as reported to have been successfully accomplished here.

Thus, fastboot and LGLAF are not required to flash a custom recovery now.;)

EDIT: I would recommend you to first try using LGUP developer feature. If unsuccessful, then try SALT as the last resort.

---------- Post added at 06:04 AM ---------- Previous post was at 05:19 AM ----------

To unlock LGUP developer options, install three files (LGUP and 02 x DLL files) from the link I have provided here. Then run the patch as provided by Hai Karate here. Congrats!!! You can now use PARTITION DL option of LGUP to flash twrp recovery.img file. Do give your feedback!

I have added screenshots of dumping a few partitions of G4 H815 for your reference. Similarly, you have to use the PARTITION DL option to flash twrp recovery.img into your unlocked V10 H901.
[T-Mobile LG V10 Android Development] NestorRamUre:
I did everything like you told me to do it man but it will not boot in to TWRP :(

This worked for you?

I tried "adb reboot recovery" but it boots into stock recovery and it just says "No commands" :(

My phone is almost falling into bootloop and i need to install a boot.img that stojshic made for the 30b version (mine), what it does is, turn cores 4 and 5 off, and technically avoid bootloop, or temporally at least... :(
[T-Mobile LG V10 Android Development] rizkhan999:
Have you been able to unlock lgup or not? If yes have you flashed twrp recovery.img with PARTITION DL option or not? If yes, any errors or not?
[T-Mobile LG V10 Android Development] NestorRamUre:
It worked for you? Contratulations man, but i had no luck :(

1. I unlocked LGUP successfully

2. I flashed TWRP recovery.img successfully (i guess...)

3. There was no errors

But when i try to boot into recovery it is just the stock recovery :confused:

Send me the recovery.img you used if you had success man

I'm almost giving up :(
[T-Mobile LG V10 Android Development] rizkhan999:
Im sorry. The set that i borrowed for testing was already in bootloop. And later on it has stopped going into the download mode. So i havent tested it. U r my lone tester. All my hopes are on ur testing right now.

Also flash stojshic boot.img using PARTITION DL option and check using CPU-Z etc whether your big cores are disabled or not.

By the way i hope u r already bootloader unlocked!!! Or not?

EDIT: Also try the dump option by dumping any partition. Just want to see if the unlocked features of lgup is even working with v10 nougat or not. Because if dumping goes successful, download also should. Otherwise wont. So dump option would really be our litmus test here.

EDIT 2: Also send me ur dll file of common folder. Want to check if it is properly patched by the patch or not.
[T-Mobile LG V10 Android Development] NestorRamUre:
I flashed with this boot.img already, but after flashing my decide won't boot, it goes right to the fastboot menu...

I tried to get into recovery and nothing, it goes automatically to fastboot menu...

Tomorrow I'll continue trying anything, but I'm almost done with this...

And sad because I don't want to get my phone with BootLoop :(
[T-Mobile LG V10 Android Development] rizkhan999:
Ok u can just try the dump option and leave everything else. Because dumping is safe as well as decisive and conclusive.

And hope u r bootloader unlocked! That must be understood but still better to ask.

EDIT: Btw if after flashing boot.img u couldnt boot, it shows that the flashing was done indeed. However the boot image did not suit ur device. May be improper size or else. U can also dump the boot partition using DUMP option and send it to me. I will have the same image modified and will send u back which u could then flash using PARTITION DL option. But only if u want to go ahead with the testing. Otherwise just test the DUMP option and quit. :)

Thanx anyways.
[T-Mobile LG V10 Android Development] NestorRamUre:
Tell me step by step man please :eek:

I'm confused about that hehe

What I have to do first, and after and after...

And by the way let me tell you that my English is not too good man

Have been unsuccessful in Flashing TWRP

So I see it's been a few months, hopefully I can still find help here.

I recently was given a LG V10 (LG-H901)

It was FRP locked when I received it, and without know that it was on Nougat I started trying to unlock it as though it were on MM or LP. So needless to say I wasted countless hours over a slight overlook.

When I got past FRP, I checked software version and it was on 30c.

I have been able to successfully flash 30b but that's the furtherest I've successfully downgraded.

I've read places where supposedly you can go back to the later versions of MM but didn't work for me.

I'm open to suggestions, phone was free to me, so whatever happens, happens.
[T-Mobile LG V10 Android Development] famewolf:
The rollback indicator was not changed from marshmallow to nougat so in theory you can downgrade by flashing one of the 20x series of Rom's....any of them except 20E which was on ARBv1 where all the others AND nougat are on ARBv2. One of the marshmallow kdz files might be posted on here somewhere.

I've got a copy of the 20L kdz you could try but I'd have to upload it and it's 1.9GB..I'm also not on what you'd consider high speed (lte hotspot). It will take a WHILE.
[T-Mobile LG V10 Android Development] Mnstr3nrgy:

[T-Mobile LG V10 Android Development] Warrior1975:
If I'm not mistaken, you can do Ota and it will just remove root and twrp, so you have to reroot and flash recovery. I'm not certain though.

Even with that it might still fail. I have at times taken the OTA.zip and removed the check for stock boot and the file that replaces recovery that is flashable in TWRP

Picked up my V10 Sunday eve, and picked up my wife's V10 yesterday Eve and I thought i couldn't be happier until I seen [MENTION=3505796]KAsp3rd[/MENTION] and [MENTION=3176005]TheJesus[/MENTION] in action breaking down the walls! Thanks A ton to you guys and whoever else was involved in this process. Took me a while to get my phone recognized by my pc for ADB. Been quite a minute since i fiddled with adb, way way back to the OG Kindle Fire, lol. I actually had to put my phone in ptp mode in order to get the pop up for adb in device manager! Go figure? If anyone out there having issues, ptp mode and nexus root toolkit got me running adb.

FYI I'm still on my first boot into twrp and only my external_sd card is showing and selectable. Will update in a few as i test a few things out.
[T-Mobile LG V10 Android Development] TheJesus:
I've messaged [MENTION=3505796]KAsp3rd[/MENTION] to include it in his OP.

ONLY PERFORM IF YOU HAVE ALREADY FLASHED TWRP AND CREATED AN EXTERNAL BACKUP!!!

1. Hold Volume Down

2. Hold Power button until you see LG screen

3. Release Power button and then rehold Power button

4. Follow on-screen prompts to perform a Factory Reset (If you have TWRP, this should not actually factory reset, but there has been one case of it doing it, that's why I suggest keeping a copy of your backup on your computer), may take a minute to boot into TWRP

5. Enjoy TWRP without fastboot

EDIT: On hold until verified on latest TWRP/more devices.
[T-Mobile LG V10 Android Development] stevepick2:
That actually factory reset my phone......
[T-Mobile LG V10 Android Development] TheJesus:
Do you have TWRP?
[T-Mobile LG V10 Android Development] Techlyfe:
Ok, finished my first backup and I must say, I was scared ****less when the backup stopped processing at 84%... And then I eventually tapped the screen and seen that it was complete! And otg is working without issue so far. Battery drain in recovery is high so make sure you have a decent charge or a decent charger nearby.
[T-Mobile LG V10 Android Development] stevepick2:
Yes
[T-Mobile LG V10 Android Development] TheJesus:
I'm not sure what the difference is between our devices then. I've done it at least 5 times now without issue. I'll talk to KAsp3rd about it.

I copied some files into my internal sdcard, in 5 minutes i'll check to see if it wipes when I enter twrp from power off.
[T-Mobile LG V10 Android Development] Airtioteclint:
Are you sure you didn't boot into android after flashing twrp? That would revert it back to stock recovery.
[T-Mobile LG V10 Android Development] stevepick2:
don"t believe so. Used fastboot to flash recovery and then booted into recovery. Have also flashed SU and some mods
[T-Mobile LG V10 Android Development] Techlyfe:
I can confirm this method didnt wipe internal sdcard files after booting into twrp from power off.

I can also confirm this method didn't wipe anything after booting to android, turning off and then booting to twrp.
[T-Mobile LG V10 Android Development] TheJesus:
After you flashed SU and the mods, did you boot into Android before attempting this?
[T-Mobile LG V10 Android Development] TheJesus:
Then I have no idea what happened. I apologize for that, I'm going to amend the instructions to perform a backup and keep it on a computer until it's performed successfully. KAsp3rd and I aren't sure why your's would do that, no one else has had an issue.
[T-Mobile LG V10 Android Development] stevepick2:
redid everything and it worked :D. Don't know why it didn't before

Just wanted to say thanks, so happy to be rooted. Got this device on Saturday and while I dig it, coming from the Nexus 5 I can't help but notice all the bloatware that I can now thankfully remove. I'm sure inevitably we'll get CM and its variants on here, but for now I'm just happy being able to purge my device. :D

Also, good clear instructions, had no issues with the process.
[T-Mobile LG V10 Android Development] rsr911:
Helpful hint

I was using root browser to move it. It moves but says failed and actually only copies. Just check that it's there then delete AdaptClient folder from /system/priv-app/

Also I did not have an external SD card in it when I started. Simplest way was to do an LG backup, open the phone on the PC and copy the file. Once rooted copy the file back to the LG backup folder, run LG backup and you're good. Oddly my Play Services needed updated and didn't work for a few minutes. Not sure what happened there.

I did all of my adb/fastboot from a Win7 VM on Xubuntu using virtualbox 5.0. Only problem I had was after installing the G4 drivers it would go into adb reboot just fine but win7 couldn't find the phone. It's showed up in device manager as "Android". I'm using the NRT (Nexus Root Toolkit) so I just pointed win7 at the universal adb driver in NRT and everything went flawless from there.

Applies to VM's only: When the phone is up and running it uses the LG driver and in bootloader it uses the universal one. When the phone reboots from adb reboot bootloader you need to connect it again in the virtualbox settings. This is super common for VM's, the reason is it is seen by the host machine as a different device so it's not connected. If using virtualbox just right-click the USB icon on the VM window and check the box for the android device. From there you can proceed with adb/bootloader commands in the bootloader.

Summary:

1) LG backup to an external SD if you want to restore your settings and apps

2) With the phone in normal running mode install the G4 usb drivers

3) once in the adb bootloader install the universal usb driver from NRT

4) After root move move /system/priv-app/AdaptClient folder to external SD then delete it from /system priv-app/ and reboot

5) If using a VM reconnect using the VM usb settings each time the phone reboots

Big thank you to the devs on this!!! I dropped Verizon and returned my S6, got this V10 and I'm rooted the next day and running flawless.

I downloaded the Linux Android Studio and plan to try it that way as well, although my guess is if you're familiar with Linux it's probably a snap.

If you installed LG unified driver, go to Device Manager when your phone is in fastboot mode, install driver manually, select a list of drivers and find LG. There's a fastboot driver and don't worry about the warning.
[T-Mobile LG V10 Android Development] Warrior1975:
