This is a compromise that Google came up with after they locked down external SD card access in 4.4.2, and their solution at the time restricted each app to their own folder inside the Android folder on your card.

When that broke just about everything, Lollipop brought this method out, and to prevent rogue apps from writing all over the place, you first have to explicitly grant access. Some apps do a better job than others in explaining the steps you need to follow.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
Hmm, that's definitely not the correct behavior. One other person reported this with a past build, and I believe they ended up having to backup their internal storage and format everything using the Advanced menu in TWRP. There was something with their phone causing items to not install properly. It even followed them to other ROMs. And try as I may, I couldn't reproduce any of the behavior, other than a single flash where I had no launcher, and one other with no keyboard.

You are correct in that only items you select are installed.

If you're up for it, can you clean flash for me and use the Aroma option to save the install log? Allow up to 30 seconds for the log to fully save before rebooting. If you select a lot of options, it can exceed 30MB in size.

i fflash it but i had a system fc and now is turning on and off the screen, im trying to get into recovery and is not working via the buttons, what's the combination again??
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] corbs24:
hold power and vol down at same time. Once you see LG screen let go power (still holding down volume) after you let go power. hold power again
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] ZDeuce2:
Above is correct, it will take you to the factory reset screen, select yes twice and it takes you into twrp. It will not factory reset your phone.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] efrommel:
now it worked, thank you!! i clean install everything just without the 3min battery, looks like the mod cause the problem with the system.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
That will happen if you selected both options for Clock and Battery. They each depend on edits made to LGSystemUI, and the #1 option is for people who want both. The others are for if you only want one or the other. If you selected #2 and #3 together, there would only be the required edits for one of them to work, but with both present you'll get thrown into a FC loop until you flash again and pick different options.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] tourbound129:
Looks like T-Mobile pushed out another update. I think it's 10j. I updated to 2.5 last night and woke up to the notification this morning.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
Hmm, interesting. I'll see if I can grab the OTA zip and check it out for changes. Thanks for the heads up.

Can't download it on my side, no option to do so. I wonder if I need to be at 100% battery. Charging up now to find out.

[MENTION=2657140]tourbound129[/MENTION] - Can you use Root Explorer or a similar app to search /data for the OTA zip? While I look for it on my end.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] tourbound129:
In /cache I have update.zip that is 134MB
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Bob Simons:
Quick question for anyone: no sound of any kind after dirty flashing v2.5 with different aroma options than with v2.4 which worked fine. Re-Flashing with different options fixed it. Didn't retry the options that didn't work as I was losing phone calls. Details below:

I clean flashed v2.4 with high impedance but without v4a and don't remember about atmos, and all was good. I then dirty flashed v2.5 with v4a and atmos and this time had no sound. . I re-flashed 2.5 without v4a, high impedance and atmos and once again I have sound. Is Viper a likely culprit? Is there a one time viper setup that I needed to do? I was missing phone calls so I didn't investigate it as much as I could have done. Was this a one time thing and I should try the aroma options again?

When the sound was not working it didn't recognize the headphones and so the hifi switch just got me the "you have to use headphones" message even when the phones were plugged in.

I haven't seen any comments about sound issues so I don't know if its something I did or didn't do, or if this was an unrelated one-off. There were no error messages at any time, no FCs etc.

Comments?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] sanjsrik:
Excellent job on 2.5

I wanted to report back that I dirty flashed over 2.3 yesterday and beyond the 10-minute wait to boot up after flashing, everything worked and is working fine. No issues so far after one day of usage.

Nice job. (so far) :)

---------- Post added at 11:35 AM ---------- Previous post was at 11:34 AM ----------

Actually, do have one question, is there any way to turn off the Android System Update notification that seems to show up only after flashing this latest 2.5 update?

Thanks in advance.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] androiddiego:
I got rid of it by long pressing the notification and disabling play services notifications. That's on a H918.

Stupid question coming...How do I do a ADB side load on recovery
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Zacharee1:
You tap the button that says "Sideload" in TWRP and then run

adb sideload zip.zip
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
To All: Thanks for the PMs with the OTA file. I'm working on getting it extracted now on my Linux machine.

I suspect the High Impedance mod may be responsible, as I ran into a few occurrances in the past where I would have no audible notifications, and they would come back after a reboot. Let me try flashing a few different ways now to check and see if I can reproduce it.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] sanjsrik:
If I get disable play services notifications, isn't that an all or nothing kind of thing? Aren't I turning off ALL play services notifications not just for ROM updates?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Lmax579:
Do I have to open CMD and how do input the zip or IMG file I want?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
What are you trying to copy to the phone? If you want to just copy a zip file over, just use adb push [filename] /sdcard [or /external_sd].

If you're trying to flash the new OTA, please don't do that. I don't see a newer recovery in there, so I doubt it will break anything, but I wouldn't risk it.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Lmax579:
The TWRP IMG...I messed up and now my phone only boots only into recovery
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] androiddiego:
Yes. I personally find the notifications annoying.

But If you use google apps, then you won't know about those updates.

This doesn't stop app notifications like messaging, phone, email, etc.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Lmax579:
I tried to flash the new recovery...I am so mad...Is there anyway to eliminate those notifications from the mobile?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
Is TWRP still on your phone, or stock recovery?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Lmax579:
TWRP
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
OK, so use the standard adb push command I gave above to copy the IMG to your phone. Then select Install from the TWRP menu, and Install Image from the lower right. You can flash TWRP from within TWRP, then just reboot directly back into the new version. You should get out of the TWRP loop after that.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
Not having much luck extracting from the OTA, going to try again from home with my physical Linux machine and not this VM at work. If that fails, I'll restore to stock and apply the OTA the old fashioned way. It's been confirmed that 10j can be rooted in the same manner.

Okay, I have a further dumb question. I installed the T-Mobile ID service without realizing what it was, now, even with root uninstaller, I can't get rid of this stupid useless software. How do I remove it?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
Just dirty flash the ROM again and don't select it. It will be removed when the /system partition is formatted. No need to wipe data or cache, so the boot up will be the same as a standard reboot once the flash is done.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] sanjsrik:
Then whatever you do don't look at this:
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] sanjsrik:
I was afraid you would say that

Will do this tonight. Just didn't want to flash if it wasn't necessary, however, as this is the only way...

thanks.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
Don't be afraid! Just flash overtop of your current install, and pick the same options. As long as you do not select Yes to wipe data or cache, you'll be up and running in less than 5 minutes. I just did it 3 times trying to isolate the no sound issue from a few posts back.

-Edit-

You could also just install ES File Explorer or Root Explorer, and delete the NameID folder under /system/priv-app. Then reboot as normal.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] sanjsrik:
ooooohhhhh, okay, thanks, got it.

On a side note has anyone else noticed that ES file explorer has become incredibly bloated with crap that pops up all the time?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Zacharee1:
Yup. I still use it though, because the interface is nice. Don't really know of any alternatives that can replicate the full functionality. Root Explorer is just confusing.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
I bought ES File Explorer Pro. None of the crap, just the old file manager we all remember.

Have you used Root Explorer recently? It was overhauled for Material Design and lost the super confusing layout it used to have. I use it more often than ES Pro.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Zacharee1:
I'll try it out.

I rebooted a few times with no changes and then changed obvious settings and rebooted and reflashed with different settings, skipping the obvious reflashing with the same settings which might have worked too. But it's working now without the mods which is good enough for now.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
The /system partition is formatted every time you install my ROM, clean or dirty. This sounds to me like something is corrupt on your internal storage that's causing this to repeat. It could also be your SD card, since there is are some system folders on it.

I would suggest backing up your internal memory, then using TWRP Advanced wipe to Format Data, followed by a format of everything other than your external SD card. Now reboot directly back into TWRP, ignoring the warning about there being no OS. Try installing the ROM again.

My phone is running through LGUP now to get back on stock 10i and then the 10j OTA from this morning.

I will fix this with the next update, but please let me say this now, and please forgive the large font:

Do NOT select more than 1 of the 3Minit mods when going through the Aroma setup

They do not play nice together and WILL cause the FC loops people are getting. I explained this inside the installer, but I'll summarize again here:

Option 1 - 3Minit Battery and Clock mod

Option 2 - 3Minit Battery mod (no clock)

Option 3 - 3Minit Clock mod (no battery)

All of these mods require edits to LGSystemUI for them to work, and if you select more than 1 of them during the install, you will wind up in an FC loop on boot. If you want both, select Option 1. If you don't want both, select either Option 2 OR Option 3.

I'll make them radio select buttons instead of checkboxes in the new version.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
OK, my phone is booted up on 10j, and now sitting in TWRP pulling the /system partition.

There is a remote chance I may take until Thursday to get the update out, so please bear with me. Walking to the train this afternoon from work, I got to experience my first time being hit by a car! ThumbsUp.jpg Low speed, so no major injuries, but I'm left handed and that's also the hand/wrist/forearm that made full contact with the Ford Edge as I leapt sideways and up to avoid having her hit the rest of me. So I find myself moving a little slower right now.

And if that wasn't enough, now my car got a tank of 87 pumped into it by an inept NJ fuel attendant (illegal to pump your own gas in NJ) after I told him 93 and he even confirmed verbally with me. This wouldn't be a big deal if my ECM wasn't tuned for 93. And with my mileage, it will take over a week to clear out the crappy gas, then another 2 tanks of 93 to get the ECM back in line.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
First go in to Settings and ensure Viper has the Storage permission granted.

Open Viper, turn on processing for whatever output you want to.

Hit the 3 dot menu in the top right, choose Exit.

Next, open Play Music and pick a song to being playing.

While the song is playing, open Viper. There should be a real quick pause in the music, and Driver Status should now show Processing = Yes

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
The update shouldn't be able to run since we've got TWRP installed. But you could delete the OTA file if it downloaded already, and also make sure automatic system updates is off under Developer Options.

But if all the fates aligned and the OTA somehow installed, 10j can be rooted using the original method.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Josh McGrath:
NATF is correct . I confirmed this morning. It just boots into TWRP.

Off topic but octane booster only adds a tenth octane! One bottle makes it 87.1 (or so)..... They don't tell you that. See if you can get some 115 octane racing fuel and mix it together in the tank. Otherwise, get a huge container and just remove the fuel line coming out of the tank while the pump is on to drain the tank. Unless you've removed the low octane fuel tables out of your pcm, then it will revert back to that and retard the timing. It's usually only about 7 to 10 HP depending on what motor anyhow.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] carandcar:
Wow. Glad you're OK! Take your time on the update.

What town are you from?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
My car is programmed to 87 from the factory, but the ECM is able to recognize 93 and increase HP around 7%.

I live just outside of Philadelphia, and work up near New York. I don't want to stereotype an entire state of drivers, but I've truly seen some amazing idiots while going to and from the train station.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dfogelstrom:
The update didn't download overnight, so I am cool on my end. Thank you!

Very true!!! I thought it was a bit more octane boost then that, but you definitely sound like you know more than I do about that. That's crazy only 1/10th!!! Good info!! I drive a 2017 Infinity Q50 3.0t and would be devistated if 87 ended up in there lol.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
This is unfortunately a common complaint with Viper on the V20 so far. Are you using Bluetooth? It has been reported on all outputs, but far more commonly with BT.

Man you've gotta be kiddin me...exact same deal. I have no idea what could cause it? i've tried downloading the file multiple times. I've tried installing from internal and external. And i've done a 100% wipe of the device for an ultra clean install. It still gives system UI crashes as soon as it gets past android is starting and then if i manage to get past the setup screens by mashing buttons the screen just turns black and will randomly flash on every few seconds for just a moment.

If you're willing to try again, can you please it without the battery option? I know the 3Minit option works, but I'm starting to wonder if another option is interfering.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] NotATreoFan:
No, I accidentally typed a command which Windows accounts for syntax and Ubuntu doesn't.

I typed "adb pull /system/bin /bin" while the root terminal window was sitting in /home/natf/v20 as the working directory. In Windows, it will pull /system/bin to [the Windows equivalent of] /home/natf/v20/bin. But in Ubuntu, it copied them to the /bin folder for the OS and pretty much broke everything.
