Raptorddd,

I am using 3g on my t-mobile variant right now. You can see in most of my post pictures the little "H" next to my cell service (LTE signal is poor where I live no matter what phone I use).

GSM arena with 3g bands:

http://www.gsmarena.com/lg_g4-6901.php

If I choose 2g, I drop all service, and my cell signal goes hollow (as opposed to blank, filled gray for poor signal). Most likely due to the 2g "sunset" in the USA. Perhaps the specific 3g band does not work in your area? When you open settings in this rom, you can choose: more --> cellular networks --> preferred network type --> 3g, and it works here. Does that work for you?

techinv,

[MENTION=7258926]Brandon9231[/MENTION] is right, it is best to upgrade to the latest modem first.

However, just to let you know, I was on 20r when I flashed the older twrp (2.8.7.0 - still using it, since it doesn't really matter to me) and started flashing these roms that I put together. With that in mind, one thing you could do is flash this rom as is, oryou could update with the linked version, then flash these.

While upgrading is probably best, I don't think it will ultimately matter. The modem updates do enable more features as the towers are upgraded, but overall can not actually increase the speed of data transfer significantly, since that is a hardware limitation. I would suggest that you upgrade one and do a speed test with both phones, you probably will not see a difference, but that depends on your area's towers. Considering it is for the kids, it may be cheaper to keep them as "slow" as possible. :)

Again, [MENTION=7258926]Brandon9231[/MENTION] is right, it is best to upgrade to the latest TWRP and modem first, but you will probably be just fine without it. Do whatever works for you. If you have time to kill, upgrade first, if it is a "get-r-done" now thing, then you could just flash them as is.
[T-Mobile LG G4] Brandon9231:
I don't know how long you've had a G4 and if this was the same in other phones but I don't think its fair to say that the firmware doesn't matter.

When we first got marshmallow people suddenly not being able to use their cameras on CM based ROMs way a huge mystery because it took so long to figure out that it was only happening to people who were behind on updates. It was an issue on stock based ROMs too because people had updated by zip instead of kdz and lost data or had random reboots.

It may be unlikely to cause bugs but I don't think we should go around saying it doesn't matter so we don't end up ruling it out should something finally come up.

Another dev actually left and took all his ROMs down because people were reporting the same bug over and over again but only half the users, those on the previous firmware, were having it. The dev and the other half of users were just going back and forth arguing about the bug being there since clean flashing did nothing and it couldn't be fixed on their end, since they couldn't replicate it

Edit: I too have been on 3g before, and switching to make it my preferred network worked too. I haven't had to do it often since I'm near Chicago, but the few times I tried it on crDroid a week or two ago it worked.

Edit 2: I just made an imgur account, downloaded their app, and uploaded a picture there to prove it, but I hate that app and decided not to post the link here. I'm uploading this on 3G too; sucks that I can't just add pictures here with an edit, but 3G definitely works

Anyone having issues with recording video? Camera works fine, a bit of a few seconds to take the pic but vid recording crashes. Will try to pull a log. Gonna reinstall with your recent update and see what happens first
[T-Mobile LG G4] Brandon9231:
Its a LOS bug, its been around for a long time. You just have to switch to the standalone recorder in the bottom right and you have to stay below 4k.
[T-Mobile LG G4] shrade:
what does the radio firmware and modem do actually? could I flash the radio/modem of other model?
[T-Mobile LG G4] AlaskaLinuxUser:
Shade,

This is one thing I do not recommend.

Flashing modems from other models could literally smoke your phone. On some phones, I have seen this done with moderate success, but even in those cases, odd things happen, such as no WiFi or Bluetooth, to even no LTE or other bands. And that was on phones which were identical between models, just with different firmware.

However, it is your phone and you can pursue any course of action you wish. I would recommend that of your phone does not have the bands you want, sell it and get a phone with the bands you need.
[T-Mobile LG G4] shrade:
but could this hard brick the phone? and could I flash back the stock modem?

The problem with the option that you recommend is that I live in Cuba, and getting another phone with the same performance is too expensive, and the market has few options.
[T-Mobile LG G4] AlaskaLinuxUser:
I personally use open camera, which works very well on this phone.
[T-Mobile LG G4] AlaskaLinuxUser:
That is a bit of a problem. However, by smoke your phone, I mean literally smoke your phone. With the wrong firmware you could cause a race condition, where the modem CPU gets too hot and burns up. In that case, it may never work again.

Then again, it may be just fine. But as you said, it is expensive to get a replacement if you let the magic smoke out. If it is working now, I recommend you leave it be. But it is your phone, and I would be excited to hear the results. ;)
[T-Mobile LG G4] shrade:
LOL, ok, thanks for the explanation, that's my only phone so I won't do it. when i can download your rom i will try it, thanks again
[T-Mobile LG G4] techinv:
A question that I didn't think I'd have to pose (have already posted in uppercut thread) however, my desktop devices are mac based at the moment. Have a working adb setup on my mac laptop that has been just fine through several of my own Android devices. I've not downloaded LGUP or uppercut yet, but seeing Windows only in bold text in the OP for uppercut makes me think it's not worth the time to download onto a mac. Is there any option that would allow me to update to 20v from a macos device?
[T-Mobile LG G4] Brandon9231:
You could use a virtual machine to emulate being on windows and go as usual. That's certain to work, but if you don't want to use that I THINK you can use LG's public software LG Bridge. I'm not too sure about how this one plays with an unlock bootloader/custom recovery though, so I'd go with the virtual machine if you can.
[T-Mobile LG G4] ElfinJNoty:
In regards to themes(SlimThemeEngine & Substratum)

Substratum team at one point accused SlimRoms of kanging their code and simultaneously removing parts of Subs that had anti piracy code.

First SlimRoms attempted to argue that they had been working on a Theme engine solution since CM ended. They then backed down very quickly when the Subs team started sharing emails and snapshots of code proving they were in the wrong.

Pretty sure things got resolved months ago. But not sure that official Substratum theme releases will ever be compatible with the Slim iteration of a theme manager. I know the Sub team said they were going to put in code to block it's installation on their rooms, but that was before things settled.
[T-Mobile LG G4] DsturbD:
So after I installed full gapps it prompts for which launcher to use. I picked google now to be default but want to use slim launcher. Where do I change this?
[T-Mobile LG G4] Brandon9231:
Go to the settings>apps>the gear icon in the top right> home app
[T-Mobile LG G4] DsturbD:
That's where it is, knew I saw it just couldn't remember. Thanks!!
[T-Mobile LG G4] AlaskaLinuxUser:
Thanks for the breakdown! That was more or less the impression I got also.

To add the commits is easy in one sense, cherry picking the oms parts is not a problem, but it affects tons of framework that needs to be reviewed for conflicts. Most of the big roms build it in, but Slim seems to have purposely cut it out. I'm just a one man band, I don't know if I will have the time to sort through all of the commits that usually are performed by a whole team. It could be less complicated than I think, but it looks pretty big with hundreds of lines of code to integrate. This is a great hobby, but as such, just something I do in my spare time.

I did "steal" the theme interface apk from another rom, and installed it with a few needed permissions files, and it "worked" but caused a lot of reboots and faults.

I'll look into it a little more when I get the chance.
[T-Mobile LG G4] AlaskaLinuxUser:
I looked at this document, yes it certainly does not list 3g.... Odd...

I wonder of they treat hspa as 4g? Or hspa+?

You've been using this phone for a while, any thoughts? Did you try the 900mhz unlock?
[T-Mobile LG G4] AlaskaLinuxUser:
Well, I was manually adding the commits for Substratum, and after 2 GB of data I decided to scrap it. Then I updated the source code, and SlimRoms is back to using Substratum! However, after building it, the substratum app crashes every time I open it. So, more work to be done here....
[T-Mobile LG G4] ElfinJNoty:
They have resolved this and are going to collaborate moving forward. Good end result for the community. ?

Slim is supposed to be continuing their own theme engine, but Subs team is going to allow it to have substratum theme compatibility
[T-Mobile LG G4] ApokrifX:
No WiFi calling, right?
[T-Mobile LG G4] stewie-droid:
I'm still on 10n Rom wiht it's 10n bootloader. Can i use old 10n bootloader or 7.1 requires it's own bootloader?
[T-Mobile LG G4] stewie-droid:
Guys i CAN NOT install ANY APPS from sdcard. Yes unkown sources is check, yes usb debugging is checked too. Supersu is installed and checked for supersu with root checker and it works
[T-Mobile LG G4] Brandon9231:
Have you tried copying them to your internal memory? It could just be that the app you're using doesn't have permission to read/write on your external SD card, did you select the right root when prompted to by the app before you can do anything on the SD card? It should've taken you to the documents app to select the root of your SD card

Edit: just saw your comment before that one, that could be a problem caused by not being on the latest firmware before flashing this. Not sure though, but it's definitely a possibility, and I've been able to install apps from my SD card before on this ROM.
[T-Mobile LG G4] AlaskaLinuxUser:
Nope, not natively. Obviously there are apps for that, but not as part of the ROM, with your regular phone number (e.g., volte).

I would recommend at least updating to pqrs or going all the way to v. I am on r, and it works great for me, but there were a lot of changes since n.

This may be a big part of your problem with the SD card asp installation. I also can install apps from the sdcard.
[T-Mobile LG G4] stewie-droid:
Thank you. So this is what i did.

So i am on 10n rom and have bootloader unlocked and twrp 3.1.1 installed. I wipe all but internal storage and installed 20v rom stock, debloated and rooted, and 20v modem. Booted up 20v rom.

Rebooted into twrp. Went into twrp and wiped everything and flashed slim h811 and it booted but camera won't work. I downloaded other cameras and none of them work either but camera works fine on 10n and 20v rom fine.

What am i doing wrong ?
[T-Mobile LG G4] Brandon9231:
I think a kdz is your only option, the camera works for everyone else so that's definitely on your end. Search for a link in the same thread you got everything else, it's in there somewhere. Look up LGUP or uppercut if you don't know how to flash the kdz. It can be kind of annoying at times but it's the only way to get back to a clean slate (but your bootloader stays unlocked) so you know issues aren't caused by your firmware.
[T-Mobile LG G4] stewie-droid:
Thanks. I did kdz and it worked. All roms now boot. I loaded Linage original one and i have a question about yours. So linage suffers from bad battery drainage. Latest build as well.

I tried cynogen back in the days on G3 and had same issue with battery drainage. Stock roms however don't. Is your code different and is that addressed in kernel or somewhere else.

There is plenty of threads on this issue actually but i see the dev never fixed it in like 5 yrs now. Love how fluid this rom is tho and tiny rom. Thoughts on this?
[T-Mobile LG G4] AlaskaLinuxUser:
SD,

Great question.

Let's take a quick closer look at battery drain issues:

You get that when:

The rom does not sleep.

The apps are going pedal to the metal.

The kernel favors performance over battery saving.

The screen is on too much.

Slimroms is, well, slim. There are less apps than stock, so unless you add more apps (which we all do), the apps in this build will not use much battery, nor prevent deep sleep.

As for the kernel, the I/o schedulers and the governors I add are not performance, but rather battery oriented.

When it comes to the screen (which is THE biggest power user) that is really up to you.

That said, I go all day without plugging in. YMMV. Depends on your settings and usage.

Hope that helps!
[T-Mobile LG G4] deltadiesel:
Slim ROM has fallen off since it was once popular years ago.....why? Because since gingerbread to lollipop, marshmallow, to nougat

It has LOST features and NEW features HAVENT been added

It needs

1. A new browser (yes that one is the worst I've ever used, and I really do expect a good one to come with the rom)

2. Substratum

3. Status bar tweaks

4. DPI tweaks

5. Disable CPU additional cores when not in use

6. Download manager ( be able select where you download file)

6. Some other new rare and exciting features. Ie. Changing color of led lights

Right now I would say it is too basic, almost stock. Great for battery and performance..

But too stock

Keep it simple, not overly customizable, but give us something

We do want slim rom back

battery and performance themes comapared to other roms and a few useful or rare features

Make it stand out again
[T-Mobile LG G4] AlaskaLinuxUser:
"This is a very slimmed down version of Android Nougat, almost a "vanilla" experience with a few tasteful perks!” --> From the opening post.

No worries if it's not your style. I sincerely hope you find the ROM you are looking for. :)
[T-Mobile LG G4] deltadiesel:
Without substratum it's no ones ROM

there is no slim

Clearly things haven't changed. Couple releases and it will be considered done till next android version

Rolls eyes

This ROM is almost stock AOSP

Someone that wanted that already has a nexus or Motorola or google pixel

No time invested = no downloads
[T-Mobile LG G4] ElfinJNoty:
First of all....

He is compiling the room from source. All your points are valid, but he isn't developing the room. Just building it for our devices so that if people want a slimmed down, closer to AOSP version of Android to run on their phones and mod to their content...... Here it is.

Second of all, OP is one of only remaining devs doing ANYTHING for Tmo H811 and he should be thanked and not criticized. He is not doing any of this and sharing just for your taste in ROM. And OP can chose to continue builds or stop at anytime. His time has already been invested, and you should be grateful he's done what he's done.

I'm not sure if maybe English is not your first language or something? I know that can cause some unintentional rudeness. But you do sound rude, arrogant, and entitled.

If this style of rom is not to your liking, than use something else as already suggested. Take your complaints about what SlimRoms is missing to SlimRom development team, not this kind guy that is simply building it for our device.
[T-Mobile LG G4] deltadiesel:
It is called constructive criticism. All the features I mentioned WERE part of the ROM, excluding substratum. What features were there are no longer there. OP slim ROM is stock AOSP.

English is my first language. I know for a fact you know you have not used this ROM. I spoke to OP myself privately and he suggested that I post it in the thread so other members could read it. That is exactly what I did.

Slim ROM was my choice of custom ROM for two of my phones, so you assuming that it isn't my choice of ROM is incorrect.

Again. This ROM is almost entirely stock and doesn't not have past slim features.

OP can do as he pleases. The forum is here for discussion and I've created discussion as to why Slim ROM is not doing well. Whether OP chooses to develop it further, or his intentions was to create a release of a stock AOSP ROM and this is it, that's his choice.

He asked for my opinion and suggestions and clearly did not agree with them.

I gave a few other suggestions what would potentionally spark more interest in it.

Again, slim ROM has fell off.

Do not care to contact slimroms, they do not care either.
[T-Mobile LG G4] deltadiesel:
Looking forward to next release with substratum if it ever comes out

Disable cores would be great too

Please change browser too (wtf browser is that) I know I can wipe it but really its a strange browser
[T-Mobile LG G4] Android_Guy:
Just flashed....seems pretty good.

One thing I noticed immediately was when I plugged in my fast charger it says "charging slowly" :confused:
[T-Mobile LG G4] AlaskaLinuxUser:
Thanks! I'm glad you like the rom. Yes, I still need to work on that.
[T-Mobile LG G4] deltadiesel:
bugs

Fast charger does not work

USB debugging and USB cable in = phone reboots
[T-Mobile LG G4] deltadiesel:
I think alaskalinuxuser is secretly turbo, slim, and black rubel

Slim steam a one man team with different user names

Always have the exact problems

Just switches names recycles same roms

Never a new release
[T-Mobile LG G4] AlaskaLinuxUser:
Hmmm..... Thanks for the heads up, but I use this room as my daily driver, and have no reboots from debugging on and plugging in the USB. Can you pull a "last_kmesg" from your procfs file after that happens? It will show me what the last things to happen were before the crash, as well as the error that caused the crash.

That is because all of us devs use the same vendor blobs, device trees, and kernel source.
[T-Mobile LG G4] deltadiesel:
Back on my old rom
[T-Mobile LG G4] rzracer2:
Amazing

Just picked up a new H811 as a retro device to play with as I like the one I used to own. I tried very hard to stay with a stock based ROM, to be honest because I liked the weather animations on the lock screen. The device is almost unusable with any stock based ROM. I use Flappy bird to test with and all (even the Nougat port) stutter. Put Slim on it and holy cow, it feels like my S8 if better. Great Job!
[T-Mobile LG G4] deltadiesel:
10 4

I downloaded new version...zip was corrupt. Redownloading
[T-Mobile LG G4] AlaskaLinuxUser:
Let me know of it is corrupt again, I had the internet quit once during the upload, if needs be, I can upload again. (I don't have great internet.)
[T-Mobile LG G4] deltadiesel:
Trying now

---------- Post added at 06:20 AM ---------- Previous post was at 05:54 AM ----------

alrighty...it worked...

only thing not working is the kernel....maybe my download is corrupt again

my phone died though...charging my phone, going to try kernel again....some error came up not a corrupt zip

got to the google setup when it died

I love when my phone goes to boot and it says slim :)

Launcher not compatible....will not overlay...

Can we change this

I like the current launcher. Just want to be able to go black
[T-Mobile LG G4] Brandon9231:
You can change it yourself? Download Nova launcher or something, the slim team is going to have to implement oms for it or your theme's Dev will. Your theme/the launcher could be outdated too, it won't apply if there's a huge mismatch in the versions themed and version installed, Google/pixel launcher are known for this.
[T-Mobile LG G4] deltadiesel:
obviously I can change it myself

developers usually have the better launchers I don't know where they get them from.....play store is exactly it says...a play store

I'm asking for developer store here

that's why I always ask developers first....I don't need to uninstall 20 different browsers file managers etc to realize theyre all crap
[T-Mobile LG G4] AlaskaLinuxUser:
Substratum is confirmed working here too. My first test I was using an old theme that was not compatible.
[T-Mobile LG G4] AlaskaLinuxUser:
That is because developers usually build the launchers from source code when compiling the ROM.
[T-Mobile LG G4] deltadiesel:
Not impressed with battery life

But then again I need a new battery

Probably go for extended one this time

Glad I can go black theme now. White strains my eyes too much

Like they say once u go black u never go back
[T-Mobile LG G4] deltadiesel:
Update

A lot of themes don't work with this ROM that would normally work with a ROM that support substratum :(

This ROM is too heavily modded with different apps that are not stock based, versions not match up therefore not compatible

It may be slimmed down but I don't see any increase in battery whatsoever. Performance possibly due to over clock....but battery non whatsoever

For substratum 20 or so themes automatically don't show up that normally would. Probably due to variations of what this ROM is based on apps versions etc

Leaves you with a few to pick from...or purchase a theme and find it not compatible. 90 percent don't work properly or won't even be listed

I highly doubt alaskalinuxuser starts changing the system with his custom apps to make it fully compatible

That's my opinion

Seems to be more like a personal ROM.... Not a custom rom.

It works pretty well other the fast charge which doesn't work at all....but isn't a vanilla android expierence....it is a personal ROM that is customized and slimmed down

To modified and personalized for me to get theme overlays working everywhere

I guess it is not for me anymore.... Its not what I am used to from old slims. Made some progress but without substratum full support I'm not probably going to use it....

Apps arnt stock vanilla...that's the problem with substratum right now as it is
[T-Mobile LG G4] AlaskaLinuxUser:
No problem, I hope you find what you are looking for.
[T-Mobile LG G4] rzracer2:
I love the ROM, so smooth but battery life is not very good. It appears it's not going into deep sleep and the CPU is running all the time. I'm trying to figure out why, anyone else notice a problem?
[T-Mobile LG G4] deltadiesel:
I had same issue yesterday. Posted it

Was running latest release 1.8 with ALU kernel

Dunno if it is kernel or memory leak..

Too unstable to use at this point for me.

Try Omni ROM by AlaskaLinuxUser it is only in alpha stage but battery life is quite good and similar to slimrom if you like this till next release

---------- Post added at 04:09 AM ---------- Previous post was at 04:02 AM ----------

Current issues with slim ROM

No fast charge

USB debugging crash boot loop

Some sort of memory leak or kernel

Substratum slightly working, but not exactly compatible
[T-Mobile LG G4] AlaskaLinuxUser:
Deep sleep is working here. This is my daily driver at present.
[T-Mobile LG G4] deltadiesel:
Battery drains fast for me too

BTW your ROMs always have Bluetooth enabled....but I disable it so it isn't the issue
[T-Mobile LG G4] deltadiesel:
AlaskaLinuxUser

Substratum just got update for nougat

Care to test if more themes are compatible now?

Any news on next release

BTW screenshots are unicorns not slim
