I don't know how I missed this information. This is so helpful. It's so much appreciated and thank you for the incredible work. Do you think it's necessary to upgrade both recoveries or does it even matter? Is it more of a preference of where you want to run twrp from? Thanks alot.
[LG V20 Guides, News, & Discussion] runningnak3d:
I am running recovery-twrp-h918-2018-05-05.img on both laf and recovery. If a new version comes out I upgrade laf and test it to make sure there are no problems, and then if it is OK I will upgrade recovery.

One of the projects on my TODO list is to add support for flashing to laf in TWRP and add lafd into the image with the ability to kill TWRP and start lafd. This gives you the ability to load download mode if you need it, without having to flash laf back onto the laf partition. Then the next time you boot download mode, TWRP will fire back up, but laf is just a "Load lafd" button away :)

[LG V20 Guides, News, & Discussion] BadToThePhone:
I upgraded twrp for laf and it worked. I'm running 3.2.1-0 on laf and recovery because that is what Super V20 requires. Is it OK to upgrade to 3.2.1-3?

The holding volume down and power didn't work. It went straight into my rom. Did I do something wrong? Thanks
[LG V20 Guides, News, & Discussion] runningnak3d:
vol down + power / when lg logo appears release and then immediately hold power. Continue holding vol down + power until factory reset appears (you can release both buttons then) .. choose yes twice and you will be in TWRP.

Until the factory reset screen appears you do not release vol down, and you only release power for a split second when the LG logo appears.

Really might want to get a reboot to recovery app :)

[LG V20 Guides, News, & Discussion] BROKEN1981:
If you don't mind, how would you do that? Build your own version of TWRP with flash recovery to laf? So we would not only see flash to recovery but to laf as well?
[LG V20 Guides, News, & Discussion] BadToThePhone:
If I'm updating to 3.2.1-3 on laf would all of these commands be the same? I'm on 3.2.1-0 now. Thanks

Thanks for mentioning that Plum, we are on the same page as I'm experiencing the same as your complete mention. I just made no mention and, still trying to get a hash match. I'm thinking of trying the vga 1..Hopefully, that might work, unless someone breaks down a dummies manual for us, lol. I so miss the day's of rooting the G-2,G-3.
[LG V20 Guides, News, & Discussion] runningnak3d:
If you can't get a hash match it has nothing to do with the FWUL install. Try a different USB cable, port or even another PC.

Writing to laf with MISC WRTE has no error correction. If you have a noisy bus, then you will never get a hash match.

If I was feeling motivated, I could do a MISC READ after every write, and hash check what was written. If the hash checked, then copy the data. If it didn't, keep retrying until it did. That would allow even the nosiest of busses to eventually get the data on there. Unfortunately I am just not that motivated :)

-- Brian
[LG V20 Guides, News, & Discussion] scorpio76r:
I understand. I'm always motivated in anything that I put my mind on. Rooting this phone is one. The reason I have a new pc is solely for this purpose.

[LG V20 Guides, News, & Discussion] BROKEN1981:
I always suggest to always make a backup. Going off my experience with other devices, you should not lose any settings since it's an upgrade. You aren't wiping system or anything else. Just after flashing each file, before you reboot, wipe delvik and cache.
[LG V20 Guides, News, & Discussion] Libraplum:
Hello guys, I am getting an Invalid Partition Selection error when I check off the Internal storage and Delvik Cache in Twrp. Does anyone know how to solve this?

Thanks.
[LG V20 Guides, News, & Discussion] scorpio76r:
Thanks for everyone's help, I have rooted and, replaced the stock rom. My only issue is that in twrp I can't fix/repair Delvic and internal storage. When I go in there I get thrown a red error. I guess I will have to go back to stock with the lg up and start over from scratch. I just can't think of what I may have did wrong. Everything went smoothly. I would really like to keep my apps, data, setup. Is there a way to fix the twrp partitions with out starting from scratch? I've already flashed twrp Phoenix image over again . That didn't help.

Good afternoon guys and [MENTION=3167089]runningnak3d[/MENTION] I have followed the direction to the tee and verified hashes and all 9 yards and i GOT TWRP but then it complained that encryption was lost so only option there was to reset the phone to factory settings which i did. Got me back onto TWRP. Did data wipe and rebooted. There is NO ROM or any other folder directory on the phone. So i'm like ok. Let's install the ROM from TWRP. So i installed SuperV20 Rom and it looked like it installed and there was NO errors of any kind.

I reboot and goes into TWRP menu. I plug usb cable AND THERE IS NO DIRECTORY besides twrp folder. No rom and any other phone directory.

It looks like twrp/phone does not have ANY write permissions. So i can't install any rom as it does NOT write onto phone, does not create any directories on the phone.

What is wrong here? My phone is now just TWRP ONLY, nothing else, no any other directories. Please help. Thank you in advance.
[LG V20 Guides, News, & Discussion] cnjax:
You need to update your twrp version
[LG V20 Guides, News, & Discussion] stewie-droid:
Thank you but i just did that. Flashed recovery-twrp-h918-2018-05-05.img Rebooted Recovery to make sure it's newest. It is. Then rebooted It booted into T-mobile screen then followed with Encryption Unsuccessful screen so I just did phone reset (factory reset) which loops me back into TWRP again and all directories are no empty again with exception on twrp folder. Back to where i was when this whole procedure ended. How do i fix this ?[MENTION=3167089]runningnak3d[/MENTION]
[LG V20 Guides, News, & Discussion] cnjax:
When you did your wipes, did you specifically format data? Also after flashing the rom you need to flash your root method before first boot.
[LG V20 Guides, News, & Discussion] stewie-droid:
Thank you for your help. I did format data instead of advance format options in twrp and in that option there is removes encyption which i think that is what solved the issue. I have also switched from magic to supersu as root option so maybe that was the issue. I dunno but it's fixed now. I see phone directories etc and can boot now to super v20 rom. Thank you for the help. I'm back in biz. :)
[LG V20 Guides, News, & Discussion] stewie-droid:

There is too much crap being installed at the same time that it's hard to know what's cause the issues. I will not be running any rooting therw roms no more but threw supersu.zip later after rom installs.

Your question was actually answered in the very first post. The Dev even made a noob friendly zip to flash.

Alternatively you could have just flashed the newest TWRP by Phoenix and flashed laf in download mode.

Why you want laf is beyond me, and most people that understand TWRP is a " get out of jail free card" would rather have TWRP replace laf.

OMG. Different carriers. The LS992 and LS997 are both Sprint phones.

Hell for that matter the H918 may be the odd man out when it comes to network unlocking, but trust me it is not the same as other models.

If you want to dump your LS997, use the patched LG UP or you can use lglaf (what is used for lafsploit).

./partitions.py --dump xxxx yyyy where xxxx is the name of the file and yyyy is the partition you want to dump.

If it is anything other than a partition on sda, you will have to edit the code.

I like the older one than the new one
[LG V20 Guides, News, & Discussion] runningnak3d:
So you just want someone to give you the solution and not do any work -- got it!

Well, here is the solution -- it is NOT F**KING POSSIBLE. On the H918, the modem firmware (which is RSA signed, and can not be changed or altered) checks with T-Mobile's unlock site EVERY TIME THE PHONE BOOTS to see if it is SIM unlocked.

When you use the app to request an unlock, it posts the IMEI to https://unlock.t-mobile.com/unlock/unlock along with whether you want a temp unlock, or a permanent unlock.

When the phone is turned on -- BEFORE it ever even loads the kernel, the modem firmware checks to see what the unlock status is if a SIM card from another carrier is detected. This happens before the kernel is loaded, so there is NOTHING you can change that will bypass this.

This is just another reason why T-Mobile firmware is signed with a different RSA key than every other model.

If you think I am mistaken -- by all means, flash the firmware from another model.

PS - I do know everything.
