[H918] Back to Stock Everything - LG V20 Questions & Answers

Saw a post in the roms section (for different variant) of a flashable to turn back to stock.
I flashed/rooted a while ago, I did a factory reset and now it boots into TWRP.
Looking to get it back to stock.
Thanks!

Reboot into twrp that's installed on recovery. Flash
this to get download mode back. Use it and LG UP in upgrade mode to flash a kdz to restore literally everything to stock.

Yes, but that is laf for the H918 -- so you are good.

Every TWRP I try to flash says:
target reported max download size of 536870912 bytes
sending 'recovery' (22616 KB)...
OKAY [ 1.505s]
writing 'recovery'...
FAILED (remote: unknown command)

It already has TWRP previously flashed in some way, but I cannot get into it. I see the logo flash up from time to time.
Tried Uppercut's LG UP and it will actually connect and give me the chance to flash a KDZ, but the phone will just do a quick restart and f*k everything.
OTA updates fail and say the software isn't verified. Also get the warning screen at bootup that the device has loaded a different operating system.
Any ideas? I just want it back to stock.

How do I boot into TWRP? Feels like a silly question...
"adb reboot recovery" just boots to what looks like regular recovery. However, when I try to update or flash a .KDZ through LG UP, it will restart and flash up the twrp logo and say twrp 3.2.1-3. So I know the fcker is in there somewhere. I want it gone... all of it.
HALP!! Please.

OTA updates and unmodified official stock files won't flash via TWRP.
Try flashing a copy of your stock recovery, then try installing the OTA update via stock recovery.
By the way, is that Charlotte NC? I ask because I live in Rockingham.

Eh... Charlotte is about two hours from me. I'm at the bottom of the mountain, but I've been to Rockingham a few times. Dad graduated as a RCHS Cougar in '78.
Also, if you didn't already know, I'm the same fool from the noob thread. Glad you found me here. So, when I say it has download mode, I mean when I hit volume up and plug in, it flashes up and says it, then shows the twrp logo, then boots as normal. Calling 'adb reboot download mode' just reboots. You think the bootloader needs to be re-locked?

Yeah, I saw you in the noob thread, I came here looking for the issue you were having.
I'm not certain about the bootloader, I own LG devices, but none of them have fastboot or download mode so I don't have experience troubleshooting flashing issues on LG devices.
Have you tried removing root and any changes you've made to system via the file manager or terminal emulator that is built into TWRP then flashing a copy of stock recovery via TWRP then reboot recovery to allow stock recovery to boot then boot to fastboot and try locking the bootloader then try flashing firmware.

I may have got it! Maybe... don't pop the champagne yet. I couldn't get into TWRP at all. It would flash up then just boot regularly. Finally I tried to enter DL mode again but this time I kept holding down the volume up button and pressed every other button like I was entering a secret code on Mortal Kombat. It actually entered TWRP!
Luckily I had already put a laf.zip and H91820f.zip on the SD card. Flashed the ROM first... did nothing except put Magisk on it... don't want. Reboot, flashed laf.zip with my secret MK code, then I had access to the real DL mode! LG UP found it and flash the real ROM. Still working on it to make sure it's all good.
---------- Post added at 07:20 PM ---------- Previous post was at 06:38 PM ----------
Yep, it's good now. Even updated itself to H91820h with no verification snags.
I shall now sell it on eBay for one billion dollars! Muahahaha!

But when you try to boot recovery, it's stock recovery.
This makes any attempt to flash a rom, regain root, etc. impossible.
And you are booting straight to recovery after flashing via volume down and then volume up to select not the power button?

After you flash TWRP, at the command prompt type:
fastboot reboot-bootloader
I can't remember where I read it but some people said they had to do that to get the custom recovery to stick.
THEN unplug your device from your computer and reboot into recovery by scrolling down with the volume down button to highlight recovery and then hitting the volume up button to select recovery.
Ok, figured this out ...
(was able to back down to the original 4.4.4 w/rsd-lite and regain TWRP ... to develop this process)
So ... the following can be done to upgrade to this new version, and retain TWRP (plus you have the new recovery later on for 5.1 when it comes along ...)
First, the presumption here is you are unlocked. If you are not, none of this will work.
Also, you will need RSD-Lite installed and operational.
Download :
https://dl.dropboxusercontent.com/u...RIZON_4.4.4_KXA21.12-L1.26-3_cid2_1FF.xml.zip
https://dl.dropboxusercontent.com/u...4.4.4_KXA21.12-L1.26-3/twrp-2.8.6.0-ghost.img
https://dl.dropboxusercontent.com/u/22067374/GHOST_VERIZON_4.4.4_KXA21.12-L1.26-3/servicefile.xml
Unpack the GHOST zip file, and overwrite the "servicefile.xml" in the unpacked folder w/the one you downloaded, then copy the twrp .img in there.
Fire up RSD-Lite, put your phone in fastboot, and apply this update by loading the servicefile.xml as the update.
It will update everything, installing the TWRP instead of the new stock recovery.
Note: you can delete the twrp line in servicefile.xml if you wish to retain your existing custom recovery.
When done, you should reboot, update, and be up and running with the new 4.4.4 and TWRP ... so easy path back to root via TWRP.

I think all that needs to happen is after you flash TWRP - you don't boot into recovery. Instead, reboot into bootloader mode. This has been a problem from the beginning for some people with their MX13's and not a new thing. I don't think it has anything to do with the update. Some people have to reboot into bootloader after flashing TWRP in order to get it to stick for some reason.
@_litz Please understand that @JulesJam is correct... the proper way to flash a recovery is as follows...
Start the phone to the Fastboot AP/Bootoader menu
using moto's fastboot (aka mfastboot) exectue the following...
mfastboot flash recovery RecoveryYouWishToFlash.img
mfastboot reboot-bootloader
Then use the volume/power keys to enter recovery.
Once in the recovery, it is safe to Reboot the phone normally.
that mfastboot reboot-bootloader step has been crucial for getting the newly flashed recovery (3rd party OR Stock!) to "stick" on the phone.
Flashing with RSDLite is over kill.
You'd think that would be the case, right?
Except those EXACT STEPS ... didn't work.
If you attempted to boot into recovery directly from the bootloader, it rebooted the phone, which booted the OS.

And you used volume up to enter recovery after flashing twrp? That is the most common problem I see.

That is because you are pressing the power button when you should be pressing the volume up button.
Yep ... ain't my first rodeo ....
It flat out refused to take recovery.
I had to back it back down to the old 4.4.4 version, reflash TWRP, then I simply applied the whole RSD package (sans recovery) to re-upgrade it to the new 4.4.4.
Worked like a charm.
(Plus it gave me a chance to extract the fxz from the moto manager app)

You needed to reboot into bootloader by typing fastboot reboot-bootloader after your flashed TWRP. THEN disconnect your phone from your computer and boot into recovery by using the volume down to highlight recovery and volume up to select recovery.
If you follow those instructions, you will flash TWRP fine. No need to go through that long drawn out process you came up with.
Probably should rename or delete this thread, since its fairly misleading.
Check in the /system partition for a file named recovery-from-boot.p or something similar. If that file is there it will reflash the stock recovery when you reboot, and I've seen it reflash when booting into recovery.
I just used the TWRP manager app from the Play store after reverting to stock recovery and installing the OTA. It worked perfectly the first time.

I'm curious as to what is different.. because the other day after flashing stock recovery back on my phone, taking the update to 212.166.3 KXA21.12-L1.26-3 which Verizon just pushed, I used those EXACT STEPS to put TWRP back on my phone and had no problems.
Beats me ... for me, it didn't work ...
So after I got things back onto the old 4.4.4 version, I put together the FXZ with the modified xml file, and simply re-updated, applying both the update, and TWRP, all in one go.
anyone else on old 4.4.4 can do the same thing if they wish, which was why I posted the links and the instructions.
not to bump this thread, but I had zero issues going from stock with 212.55.26 ota update installed and flashing twrp. it just worked like normal.
i would agree with @superkeest seems like this thread should get renamed.

Safe to reboot? axon7toolkit boot.img remote: unknown command

Hey everyone,
I am in the process of rooting my axon7 (B10) and need some quick advice
I unlocked the bootloader using this method: https://forum.xda-developers.com/axon-7/how-to/guide-unlock-bootloader-easily-t3704595
Then went on to install twrp using the axon7toolkit. steps 1 and 2 reported to be working correctly but during the twrp install this came up. (see attached)
okay so recovery flashed successfully, but something went wrong with reboot? why, how, there is no indication that the tool wrote anything to boot.img so I should be fine? Can I just boot to recovery manually and continue normally? Or should I be worried that something went wrong?
the phone is currently still in fastboot mode and responding. however I am super cautious and don't want to brick the phone because I didn't ask so I am keeping it in this state for now.
any help is much appreciated

Why do you even use axon7toolkit? Use "fastboot flash recovery recovery.img" and you'll be able to avoid using the toolkit. It's finicky as hell.
Otherwise at least use EDL Tool...
Your boot image is untouched. Seemingly axon7toolkit does "fastboot boot recovery.img" which basically sends the recovery to RAM or something and makes the phone boot into that file instead of the actual boot.img.
If you are on Fastboot select "Recovery" from it and hit power. It will enter the recovery directly. This is important because if the phone boots, it will reinstall the stock one.
After you get into TWRP, FLASH MAGISK. This will let you retain TWRP.

yeah I don't know why it seemed like a good idea, it's a sticky post in the rom section... It's how I started and then wanted to stick to it somehow.
indeed booting into recovery works like a charm which is already pretty reassuring.
flashed magisk, twrp is not up to date (3.1.1.0), but system boots. thanks a bunch
I guess I'll update / flash the most current version of twrp via fastboot and then go on to flash lineage
again, thank you very much

Is your twrp installed as "Keep Read Only" or did you select "Swipe to Allow Modifications"?
After giving flash in the Magisk you gave wipe?
Thanks if you can respond.

If you're asking because you want to know:
-swipe to allow modifications is okay
-If you want to get rid of encryption, you have to FORMAT data (not wipe). You'll lose the internal storage. After that, flash magisk.
You can just flash it without formatting , but your storage will be encrypted, and you'll lose the internal storage if you ever change ROMs.
I swiped to allow modifications
I backed up everything I needed from the phone. I actually planned for removing everything to get a fresh setup.

So after installing twrp I format the Data partition and give flash in Magisk, correct?
I am afraid to enter bootloop because I have already done several procedures and in all the same thing happened. I hope everything will work out this time.

[SOLVED]Tried to update Magisk from app, stuck at Fastboot screen, TWRP may be gone

I fixed the problem by just booting into the LG Factory Reset menu, in order to get into TWRP. I hesitated to do that for a while because I had no way to verify TWRP was still on my device. After running out of options, I decided to just go for it. To my (and probably no one elses) surprise, it went straight into TWRP, where I was able to flash H91820s and Magisk 16.0 in the same TWRP session. Rebooted, everything was how it was except on a new version of Android. Root was retained.
Tried to update Magisk on my TMobile H918 from Magisk version 16.x using the app, and selected Direct Installation. The device is now stuck at the fastboot screen, and I cannot boot into recovery from adb.
Is there a way I can repair things? I am unsure exactly what got deleted/corrupted in the process of the update.
EDIT: When I try to boot into TWRP, I get this error:
fastboot: error: cannot load 'recovery': No such file or directory

and when I try to re-flash TWRP, I get this error:
fastboot flash recovery twrp.img
Sending 'recovery' (28928 KB) OKAY [ 0.764s]
Writing 'recovery' FAILED (remote: 'unknown command')
Finished. Total time: 0.827s

Can you get in Twrp with button combo? For me its while boot hold vol down and power then at lg logo release the power for a sec and re hold until the while screen and then select yes twice.
There is also download mode and reflashing twrp that way I believe...
Dont 100% me on that .

I tried to boot into recovery, but adb detected no recoveries on the system.
I don't want to do the System Format Yes Twice thing because I believe TWRP is gone. And I am unable to re-flash due to "no such command."
The recovery is unable to be written to the device.

Is the phone in download mode ?
adb doesn't work in download mode
What does the command fastboot devices return?

I fixed the problem by just booting into the LG Factory Reset menu, in order to get into TWRP. I hesitated to do that for a while because I had no way to verify TWRP was still on my device. After running out of options, I decided to just go for it. To my (and probably no one elses) surprise, it went straight into TWRP, where I was able to flash H91820s and Magisk 16.0 in the same TWRP session. Rebooted, everything was how it was except on a new version of Android. Root was retained.

Glad it worked...happy new year

Trying to flash TWRP but no success (stuck on Fastboot mode)

I have been on a journey trying to go back to my T-Mobile OnePlus 6T back as my daily driver but the official updates killed the device for me. I have been successful in flashing it to the international version and now the device is on A9. I am trying to get it updated to A10 but in order do that (does not take OTA updates or can not flash within the updates app) I have to flash in recovery. Right now it is on stock recovery so I am trying to flash TWRP.
The problem is now that everytime I run the command " fastboot boot IMAGENAME.img" the phone restarts (as expected) and boots into fastboot but stays stuck in the Fastboot Mode screen.
I tried different TWRP images (older and the most current version per https://dl.twrp.me/fajita/ ) but I keep getting stuck in the Fastboot Mode screen. The last thing I was able to do without issues was unlock bootloader using fastboot.
I just need to be able to flash TWRP on the phone so I can still the final stock image so I can go back to using it as my DD.
EDIT: Disregard everything I fixed it. mods, please delete thread.
EDITR 2: Disregard that last edit lol Yeah I still need help. I am now tryingto flash twrp on a second 6T and the issue described above still applies.
You can try this version. Also try unplugging the USB after it reboots. You aren't getting any crash dump screen? So it should be working.

Tried your image and still same result. I am running following command
Code:
fastboot boot TWRP-3.6.1_11-OP6xT.img
The command window outputs the following
Code:
Sending 'boot.img' (34964 KB) OKAY [ 0.747s]
Booting OKAY [ 0.092s]
Finished. Total time: 0.860s
The phone then reboots into Fastboot Mode logo and stays stuck there. I even tried unplugging the USB after it reboots as well.
I even tried using the flash command instead of boot but no success.
How about fastboot boot recovery? Should be able to get into recovery somehow. Doing fastboot flash of twrp will mess up your boot partition but either way you still should be able to get into recovery somehow. There is the msm recovery tool you can use as last resort but it will relock your bootloader
Actually fastboot doesn't let you use boot recovery command I don't think. Only adb. But once you are in fastboot can't you choose to reboot recovery with volume keys?

When I am in fastboot mode, yes I can choose recovery but it takes me to the stock recovery. I do not have a option to flash any zip files there
Maybe you need a twrp for Android 9 since that's what you are on. But fastboot boot twrp should just take you there. Either have to find one that works or go msm route. Maybe windows not reading it correctly also. You using CMD or PowerShell?

I tried both CMD and PowerShell. I am going to try a A9 version of twrp
EDIT: I am using twrp-3.6.1_9-0-fajita.img (which I assume is for A9) and still get the same result. Even tried a different usb port.. not sure what i could be missing. I also did the instructions as advised straight from twrp's website.

I don't know bud. I guess msm tool is the way to go then
Curious did you have the twrp file in same folder as adb and fastboot?
