How to apply Android Security Patches to a Custom Rom?

How to apply Android Security Patches to a Custom Rom? - General Questions and Answers

Hi everyone,
I've used Android-based custom roms for years on many of my devices. Now, I am only able to find one old Lineage OS 14 build for a rare, old tablet that I have.
The Android version is not a huge issue, as many Apps still support 7 and lower and the system itself runs reasonably well. However, the latest security patches are still from 2018.
The way I understand it, Google/AOSP publishes some sort of security update packages in regular intervals.
Is there an easy way to appy those patches to the rom that I have? Reinstalling the system is no problem and I can do some simple troubleshooting, but I'm probably not able to recompile the entire build, if that is necessary.
Unfortunately, since every custom rom has some "Security update" info, it's extremely hard to find any explanations of how to actually apply those patches, at least I couldn't find any.
Fell free to just send me a link if there is any sort of guide on how to accomplish this.
Thanks a lot!

You have two problems here.
First: Google does NOT publish security patches for every Android version forever. After some time (3 years i think) is that Version deprecated and does not become patches from Google.
Second: those patches are not in form of a "ready-to-install" software. They are source code patches. You can see them as something like _r67 after the Android Version. So you or someone else must build them.
For a recent, supported ROM like LineageOS 18.1 the ROM developer does this for you. You get it when you update Lineage.
For Android 7, which deprecated long ago, someone has to port this patch. It's not possible for every patch and if it is possible, nobody does it because it's a lot of work.
Short version: if there is no ROM based on Android 10 or 11 for your device you have to live without patches :-(
Hope that helps.

Well, yes and no.
But thanks for clarifying. I hoped there was a way to install those easily.
Do you happen to know if, hypothetically, I even had any chance to patch my rom with just the flashable zip or am I missing some crucial source files?

You can download the sources of Lineage OS 14, patch them, compile them, install them and you have all the security fixes.
As said. This is a lot of work and requires good amount of knowledge. With that time and energy you could port Lineage OS 17 for your tablet instead.

[ROM][CM/AOSP][JB/KK] sediROM for LG Optimus F3Q / D520

sediROM for LG Optimus F3Q - Custom ROM (codenames: fx3q, d520)
This is about building a custom ROM like Cyanogenmod or AOSP working on the LG Optimus F3Q.
Introduction
First of all: At the moment there is no CM or AOSP based ROM available for the F3Q. Not yet.
That said it means I try to port CM (or build pure AOSP) to the F3Q and this is this thread about.
Some words about me and what I do:
I do Android ROM development since June 2014 mainly doing things based on stock.
Before the F3Q I never had to do with porting CM or AOSP to a brand new (no not such "new" anymore) device before.
New means "no file device tree" etc available. So I dive into porting months ago and still learning every day new things here.
Porting is nothing you can learn in a week or so The main problem with porting is that there is not much you can read or
where you can get many help for. The guides out there are very generic and to be honest the best would be having a pro on your site
which guides you through all the problems which WILL occur when porting.
Before starting I never heard about "loki", doesn't know how TWRP gets compiled or created an Android kernel with or without CM
automatism. In the meantime I compiled a working TWRP version, having a kernel in place which allows to boot unsigned system
images and many more. The only "little" thing left is to get CM ready.. Nevertheless I have 2 things which helped me a lot over
the years: patience and "never-give-up".
The state:
If you ever tried to compile Android or CM by your own you know that you need a valid file device tree (in this case "device/lge/fx3q/")
which contains all the stuff which describes the hardware, the things to do, proprietary files you cannot compile because their sources
are kept by LG and so on. Building that from scratch is a pain in the a.. so you need to find another device whose hardware is as much
the same as yours. In this case this means LG Optimus F6 which has the same processor etc. The great thing is that there are people
out there who had build a working device tree for the F6 which means it should be possible to have the same for the F3Q!
The problem is that before I used the DT from hroark and fixed several build errors there and well now I use the very much more newer
one from dm47021 and this means: adapt everything again, fixing build errors again..
Even when there is such a valid base available from a device with same specs this does not means it would simply work when copying
it over.
I need to adapt nevertheless many things to get the sources at least compiled! and then the question is what works and what not.
This is where we are atm: Fixing compilation errors (fix 1 and you get 2 new) and then we will see..
For updates about the state scroll down to the "current state" topic.

Done:
Lokifying (without that we were absolutely L-O-S-T!!! BIG thx @djrbliss) process is done automatically by my self created build-script (took me some time but was it worth)
Lokifying means: due to a hack by @djrbliss (click here and click at his THANKS button!!) we can trick the locked bootloader to boot whatever we want!
boot a modified compiled kernel with the stock ROM / or hLe stock ROM
custom 3.4.0 kernel with kexec(disabled atm), xattr, selinux support and much more based on the stock kernel sources (sediKERNEL thread)
the ability to boot unsigned ROM's provided by sediKERNEL
Fully (or mostly) working TWRP version where storages correctly mounted and backup/restore working fine (TWRP thread)
adapt hroark's device tree of the LG optimus F6 to the F3Q (superseeded by dm47021)
adapt DM47021 DT to F3Q and compiling CM KK systemimage/full otapackage (do not expect too much it simply means that I was able to fix all the thousands of compilation errors. which is GREAT but now the debuggin starts)
Rebasing EVERYTHING of the file device tree to the f6mft one by Dm47021. Reason: CM is now available for the F6 which is damn great because we use the same hardware in many cases. I currently rewriting everything from scratch, adding the correct proprietary files etc. Will take a while but hopefully then we get more in the right direction then before.

Questions & Answers
Frequently Asked Questions (FAQ)
(in no special order)
Question #1: Is CM or pure AOSP (or similar) for this device available now?
No. Not AFAIK. If you find some please tell me! But afaik I'm the only one working on that port so if you find someone or you want to help by yourself please send me a PM!!!
I currently trying to port CM to this device and as I'm doing that alone and the whole process is very complex this is nothing you can do in 2 weeks or so.
Question #2: When will be CM or pure AOSP or similar available?
When it is ready. Sorry but for this no timeline can be made. I will update the OP from time to time so come back often to check if there are any news.
Question #3: Why are you doing this?
Well .. the main reason is I want to have an absolutely fully localized (German) Android for my wife. Yes it's that simple. There are plenty of apps who can switch the language in many dialogs but all LG ones (like settings, power menu etc) are all still English.
The following may harm you but the F3Q is not a device I would buy for myself. I do not really like it's design, it has more weight and height than my current one (Samsung i927). Ok not all is that bad: What I really like is the physical keyboard which is much more better than from the i927..
Nevertheless I own a F3Q since a while because the community sponsored one to me which makes it possible for me to continue developing for this phone. Otherwise I had stopped that at the time where my wife used her F3Q productive.
The other reasons are:
There are problems here in Germany regarding the reception: 3G (or better) is not possible (but it should be from the point of technical specs).
Besides that the displayed information about the speed seems to be wrong in some cases but that is another story..
Last but not least the problem of overfilled storage makes me mad (well in fact makes my wife mad but well that makes me mad then). There is always to less even with tricks like moving apps etc.
So in short: I want to be able to fix problems who are annoying me/my wife.
Question #4: I have bought the phone and need to unlock it (service provider lock, network lock, ...) now. How to do that?
Well there are thousands of services out there who offers unlocking and no guarantees wherever you go.
Just 1 thing before you read on:
I'm not responsible if the mentioned site doesn't work for you! For me it had worked but there are no guarantees out there in the evil internet ocean...!
The following describes my personal experiences with those services only. No guarantees no responsibilities no whatever.
I have tested 2 of them:
The first one is a "free" service named www.unlockphone.me.
Free means first of all: WAIT. As an example my request have this as the waiting time:
1027 people are in queue in front of you. 2 weeks, 3days, 10hrs, 14min remaining until you will receive your CODE
The service itself is free but as I do not wanted to wait such long I donated to them 10$ to receive the code more quickly.
Result: Well I got a code but is was not working. I send them 4 mails - never received any answer. Bad luck. That is what I mentioned above. No guarantees. Well you could try it on your own - at least the free one without a donation - and see what happens for you. It's may worth the try.
.
The second one was fine. To be sure: I do not own the following service or get anything for pointing there but I have used them 2 times and at least the service provider lock could be unlocked both times successfully. The first time used they unlocked for $2 CAD (November 2014) and today (April 2015) they unlocked for $7,50 CAD.. Well it still seems to be a reasonable price (at least for me).
freemyblackberry.com
I filled in the following:
Brand = LG
Carrier/Country = USA / T-Mobile
Model = LG Optimus F3Q
When you have received your code (the one way or the other):
if you do not see the unlock screen already type in the following in the dialer: 2945#*520#
in the displayed menu choose the type of unlock you want to do (in my case it was service provider locked so I choosen that)
type in the received unlock code (for my case the freemyblackberry named it SPCK)
the phone may reboot now automatically
enjoy.
Question #5: What can I do to help?
I thought you would never ask! :victory:
The first one EVERYONE can do even when no programming skills is: Use the "Thanks" button. :good:
This is simple, easy and can be done very quickly. This will not speed up anything of course but it keeps me motivating because it shows me that you like what I do.
.
The second one EVERYONE can do is to participate in beta testing versions.
From time to time I release a new Kernel or TWRP version or some day a CM version. If you want to help you should do that by installing those beta versions (if one is available) and telling me about the good and bad of it.
This needs always a full backup and you may need to restore things afterwards but I'm here to assist you as far as I can.
.
The third one is not for everyone: helping to port.
That means going to the steps of CM porting guide and downloading the LGE sources and cloning my git repos. Get in contact with me before so you use an uptodate repo like the device tree etc.
This one would be the biggest effort but it is the most time consuming. At least for the full port.
If you "only" want to help partly like making TWRP better or helping with Kernel development it will be much much easier because those both are already fully working and you can start with fixing things instead of try&error!
That said Option 3 here is the only option if you really want to speed up the process!
.
The last one I can think of is donating, of course. I do not beg for money here - it is simply one of the available options.
One thing about this is important: a donation is much much more motivating then the mentioned "Thanks" click but you also will not speed up anything (Ok you would speed up things when the donation is about 10.000 € or more haha)!
But seriously: I do all that in my free time atm and that means I need to cut out time somewhere else from RL. This is not a problem for me and if you donate or not I will continue until I reached my personal goal.
That simply means that it will take much more time than doing it full time. The only other option would be developing in the normal work hours which means not earning money here for this time. So there needs to be a balance for if I would do that. That said there will be times where I can work on it and may times not for weeks. It depends.
Question #6: What is that "adb" thing?
adb stands for: Android Debug Bridge and can help a lot when it comes to work with your device. It is not for developers only but they use it a lot of course.
But a normal user can use this to exchange files without the need of mounting, backing up the device, reboot the device and use it as a very comfortable way of having a terminal emulator.
.
Normally adb itself is not available as a standalone application - it comes with the Android SDK which is very big and heavy if you want to use adb and/or fastboot (another great tool) only.
But we live in a great world with many people wanting to make things easy so here you go when you want/need only adb and fastboot:
download & install adb @lifehacker
Question #7: How can I find the LG Hidden Service Menu (STOCK)?
Normally you will not need this! But you may want to enable the USB DIAG mode if you're a developer or you simply want to make your phone unusable - so here we go:
As usual: Use on your own risk!
adb shell
su
am start -a android.intent.action.MAIN -n com.lge.hiddenmenu/com.lge.hiddenmenu.HiddenMenu

I know I am getting ahead of myself, but I know some devices have a /datadata partition (like the Samsung Infuse) when ported for a KitKat ROM.
When it comes time to design for KitKat, can this separate partition be eliminated? I know it is done for performance reasons, but with such limited userdata space as it is, another partition would come as a detriment. This has already proved a problem on the Infuse, and they have much more space to deal with (albeit ~600mb /datadata).
The alternative would be building Link2SD into the ROM, knowing that there will still be only a small collections of apps that can be installed.
Unfortunately, because of our limited userdata, we probably won't be able to develop past KitKat, at least end up with something usable. ART will prove to be too much of a pig for this device (storage wise).
Just my nickel's worth...

Bad news..
The Desire Z of my wife is completely broken now.
That means I cannot develop anymore..
- I ported and released the latest TWRP version to the F3Q
- I'm able to build AOSP JellyBean (not booting yet though),
- I compiled and released a custom AOSP Kernel (named sediKERNEL)
.... and a lot more..
I have everything I need to continue here in place...
I have the will and the ability to continue...
But no device anymore..
If someone has a F3Q to give away.. then I will continue but I'm not willing to buy a F3Q for developing only. So if you have an idea how we could continue let me know.
Otherwise that will end here for me unfortunately...
Hopefully not.
Yours
Xdajog.

Kexec Kernel = Porting to F3Q (hopefully) finished. compiling OK but it has problems with mounting the correct places (I think. Didnt investigate that further atm)
Well one of the ideas is to have a working MultiRom installation which then would boot a custom ROM like CM with the kexec technique.
That way we could boot a "insecure" ROM with our locked boot loader.
That really seems to be possible because I can flash a TWRP image to the BOOT partition for example. That means TWRP would start up everytime.
If we could get MultiRom in place where the boot partition sits we COULD be able to boot everything we want.

Just so im clear what exactly is incomplete about the cwm that was compiled? you say its not a valid device tree (crazy because ive never heard those kind of terms even used before) what exactly makes it invalid to you?
what was the point of labeling this thread? gain some thanks by saying you spent 200+ hours on compiling the stock kernel source that has a guide to compile it in teh source zip? cuz it doesnt appear to make any progress on booting aosp even though you forked an oudhs device tree from another device. then you talk about needing hacks etc to get past the locked bootloader yet you dont seem to understand that there was an exploit tahts how there even was a cwm.
instead you are pulling in search results giving false hope to people looking for cm in hopes they donate to you so you can buy a phone when you obviously dont understand how it works.

Never said that CWM is incomplete but to be honest it was and it is missing features TWRP has, of course. It is a while ago that I took a look at that CWM version so I would need to check again maybe. The last time I tried it the mounting of /data/media (the internal usb storage) was not possible as backup, too. But that may have changed.

You may have more experience in porting to a complete new device so what is wrong with forking from a device which has more or less the same hardware specs ? That is the recommended way mentioned in the porting guides.
The reason why there was no progress since a while is:
I had no device anymore
Donation offer took some weeks
Then the new (used) device need to be shipped for about 2 weeks
Then I was on vacation for 2 and a half weeks
Then I needed to bring down the workload in RL to continue which took me another week
Then I started with development again since 1 day
Today
The main focus is to develop a fully working initial ram disk build from scratch instead of using the stock one. Then I will continue on porting AOSP as the ram disk is an essential part as you know.
then you talk about needing hacks etc to get past the locked bootloader yet you dont seem to understand that there was an exploit tahts how there even was a cwm.
Click to expand...
Click to collapse
Well it seems that you do not understand but that is not a problem I explain it for you:
The locked bootloader is a problem because normally we have not the possibility to install a custom kernel and/or custom ROMs. There is a hack available named "loki" which makes it possible to circumvent that fact. The only thing you need to do is to use the loki patch on the kernel/boot image.
The other thing around this is that the bootloader send kernel boot parameters which avoid starting a custom or modified ROM. This is one of the examples I fixed as you can see in the kernel thread and the reason why the modified stock ROM from @joel.maxuel is booting.
The multirom thingy (you may point to) was about having a special boot image (based on TWRP) named multiROM. With this it would be possible to power on the device and choose different ROMs you may have installed (that means different ROMs on 1 device in parallel). Great thing and at the time of writing one thing I tested. The main problem here is not using the Loki patch mentioned above but instead the /data/media internal storage which need to be mounted correctly and some other things as well. Nevertheless is multirom nothing I want to work on atm because the main part of work is to have CM/AOSP compiled and working.
what was the point of labeling this thread? gain some thanks by saying you spent 200+ hours on compiling the stock kernel source that has a guide to compile it in teh source zip?
Click to expand...
Click to collapse
I never said that I spent 200+ hours for compiling a stock kernel. Please read carefully before getting rude. This thread here is for developing on the F3Q ROM not the kernel. Kernel things are located in the Kernel thread. (Btw. compiling the stock kernel was never a problem or somehow time consuming there are other things like the initial ram disk and correct mounting paths etc which had taken some time but that is another story and as said not related to this thread.)
You may have heard about people porting ROMs to new devices? I try to do so and that is the reason why this thread exists. Not for some thanks clicks - some people define their self not with this you have to know. To be honest I do not get paid for everything here - which is ok. So a thanks click is appreciated, of course. Nothing more nothing less.
btw: I believe that a user can decide on their own if they want to click thanks when they want right? TWRP and Kernel are both things ready to use and the ROM porting is a WIP which a user can or can not say thanks for. That should be decided by the user IMO.
instead you are pulling in search results giving false hope to people looking for cm in hopes they donate to you so you can buy a phone when you obviously dont understand how it works.

To be honest it seems obvious that you do not understand. That is not a problem because I can explain it to you again.
As stated before and in the OP I try to port AOSP and/or CM to this device. Well it is true that I'm still learning and will learning forever but that is the truth for everyone (maybe not for you, ok ).
The donation part is something which was an offer to continue the work because I do not owned the device anymore but I was and I am willing to continue. As stated in the the donation thread I do not use the device for anything other then development because I do not really like the phone itself. But my wife uses the phone and she needs CM / AOSP to be able to be fully in German language and having a smoother Android experience than with the stock ROM.
If you know everything better than me then why you do not share your knowledge so we can speed up the process of porting? Would be more efficient than writing

......and another thing I want to mention today!
The following has been done 10 minutes ago:
adapt DM47021 DT (device tree) to F3Q and compiling CM KK systemimage/full otapackage
This is 1 step further into the right direction but do not expect too much it simply means that I was able to fix all the thousands of compilation errors for the new adapted device tree.
Which is GREAT, of course but now the debugging starts and recompiling etc ..
The first boot was a mess I believe it has to do with a wrong used gcc version but I need to investigate that further in the next days/hours whatever..
just wanted to keep you updated

adapt DM47021 DT (device tree) to F3Q and compiling CM KK systemimage/full otapackage
This is 1 step further into the right direction but do not expect too much it simply means that I was able to fix all the thousands of compilation errors for the new adapted device tree.
Which is GREAT, of course but now the debugging starts and recompiling etc ..
The first boot was a mess I believe it has to do with a wrong used gcc version but I need to investigate that further in the next days/hours whatever..
just wanted to keep you updated
greetings from the front
xdajog
EDIT:
if someone interesting in This is the time duration of a full cleaned compilation (real = the actual duration):

My hat is tipped to you xdajog. I'm looking for a qwerty slider replacement phone for my wife as her current one is reaching 5 years old soon.
Your efforts have tipped me towards this phone as a working ASOP or CM would be necessary as I do not think this phone will be updated by anyone else. I'm always leery of putting a family member on anything past a feature phone unless I can be confident of keeping it patched. Since there are no flagship phones with qwerty keyboards the efforts of devs like you are all the rest of us have.

@xdajog than you truly for your continued support on this device, i am a late adopter to this phone but is there any hope for getting android 5 on it?

yes, but the lg optimus f3 and f3q have the same specifications and the same kernel, the difference among them is where it was manufactured and the f3q comes with a keyboard and different touch buttons, take a look at the comparison below:

Of course. Thats the reason why I use the F3 device tree as base for development. But there are many differences in compiling. If you want you can try would be nice to have another dev here.

Yeah, i will try, give me the a one time

So I've got an Ubuntu 14.04 LTS VM set up on my machine and I downloaded the Android source tree (AOSP) and configured the build environment per the instructions. I ran a build and everything came out okay (but slow ). I have some additional RAM on order for my machine so I can dedicate more resources to the VM.
I have an extra F3Q I can use for testing and I have a pre-paid SIM on order so that I can actually use my test device in real-world scenarios.
I'm ready to start digging in here. :good:
Edit: RAM arrived today, have 32GB now which means I can dedicate a full 16GB to the Ubuntu build environment!

Hi! I've installed it in multirom with a stock 5.0.1 as primary and it works, just tried it for few minutes.
just be sure to have the latest bootolader (HHZ12h) or installation will fail.

Flashing a bootloader
Hi,
I have a Nexus 5 and I use Multirom with it. My default ROM is Lollipop 5.1.1 and a secondary ROM, which I mostly use, is Marshmallow 6.0 (xTraSmooth). I want to install CopperheadOS, but it says when installing, that I must have HHZ12h bootloader in order to install (as stated in a previous post). My current bootloader is HHZ11k. If I install HHZ12h bootloader by flashing a zip file which includes LMY48B_Radio+Bootloader-HHZ12h will it cause anything that prevents Lollipop or Marshmallow to work properly?

You don't need to downgrade the bootloader, just modify the updater script of the rom ( deleting the string containing the bootloader version or replacing with your current version), then it will install just fine.

Can anybody provide link on COPPERHEAD OS ? CHEERS!

Thanks! I haven't tried that yet, but I will. First I thought I can just replace HHZ12h with HHZ11k using text editor, but then I noticed there are guides which suggest that it isn't quite that easy. I might be wrong about that, will see when I have enough time to read up on the subject.

It's easy, just extract the rom, go to Meta-Inf/com/google/android and modify the "updater-script". That's all, rebuild the zip and flash in recovery.
Edit: you can do it without using a PC, by using a file manager on your device.

Just installed it on a Nexus 5x and it works flawless. It has most of the standard stuff but is different from the rest in that it is supposed to be security oriented. That means no default root (but rooting should be possible).
I didn't try to add Google stuff yet and probably won't even try to add that spyware but it does have the F-Droid app store.
There are some extra options to secure the memory if required, and the documentation is (so far) very good (for example the install guide and the technical overview).

Currently running it on my Nexus 5x and N5. works great. Anything you are missing you can find on F-Droid. I find the lack of data usage to be delightful; when facebook or ebaum videos auto load on other software, they are stopped on copperhead. very happy with the security.
The only thing i can not make work is voice to text, and I have a ticket in with copperhead. who cares, I have fast thumbs.
Nexus + Copperhead = Happy Gopher!

Thanks for the feedback. I guess manual apk installation is also possible?

I'm thinking about picking up a Nexus 5 as a backup device, and CopperheadOS seems like something fun to play with, instead of just installing CM13. Can I install TWRP as recovery on devices like the Nexus 5 that don't check for locked bootloaders? Can I run it as basically another ROM –*unlocked developer options, root, TWRP, etc.? I realize the OS exists for enhanced security, but I'd like to make a few tradeoffs.

Unfortunately, you can not run TWRP with copperhead, it wants full control of the phone for security reasons. Its not meant to be a developer OS with access to all the bits, so you kind of need to want a OS in a box that you can deal with.
But I have to say, despite its shortcomings of not having google services, it works pretty much flawless on my 5 and 5x. i miss google maps app, but it works 100% via chromium browser as a favorite, and I have only found 2 apps I can not import via apkmirror, one being Waze, the other is my local public transportation app. other than that, i feel like I'm safe from prying eyes.

Thanks for your response. I'm a fan of CyanogenMod, and I'm not unhappy their security or features, but I wanted to play around with CopperheadOS. I understand the tradeoff between security and convenience, but I'm not willing to sacrifice TWRP in the mix. Oh, well – if I ever have need of an OS solely for its security track record, I know where to go.

It doesn't look to me like Copperhead is supporting the Nexus 5 anymore. Can somebody confirm or is there a link I'm missing somewhere to the ROM?
EDIT: Yep, I knew it was deprecated for a while now but they've even removed the deprecated ROM from the site now. I'd appreciate it if anybody has the last ROM if they could pass it my way.

Switch debugging OFF and don't lock bootloader after CopperheadOS install and u will be able to boot TWRP via
fastboot boot recovery.img [TWRP]
I'm currently experimenting with root privileges on CopperheadOS on Nexus 5X. Still haven’t tried xposed framework.
Security features r quite good, especially different lock code && encryption password and memory protection, but, there is a lack of fine privacy control (Privacy Guard) as in CyanogenMod and firewall, hence the need for root.

I've been using CopperheadOS for a few weeks now on the Nexus5. Received the latests OTA a few days ago and applied without issue.
Installed it via TWRP. Have rooted the device with SuperSU, though have to re-root after re-flashing recovery after each OTA.
It's been working great.
Unfortunately I don't have the img any more

Does quick charge work?

Been running for a couple of days now without issue.

Yes it works, I've beeen using 2 QC3 chargers with no problems at all.

Awesome, works great so far. Here are a few things I noticed :
1- Keyboard didn't show up easily during setup, but eventually it became smooth
2- Following apps did not install (Package Helper error) : Fitbit & Spotify. Spotify was a known issue in stock rom but Fitbit was working fine in stock.
3- Netflix is not available. Previously I had LineageOS 13 and I was able to install Netflix. I know they banned uncertified devices, but I was still able to get it with that rom.
4- Fingerprint is not working 100%. I am able to unlock the device with it but apps are not able to use it properly. For example try Starbucks or any banking app. They will ask if you want to use fingerprint, you say yes and you put your finger, some apps crash, others will say fingerprint recognized, but then they don't actually store/use that fingerprint? Something must have gone wrong... LineageOS 13 also had this issue, but stock rom did not.
I would like to know if it's possible to not have the customizations you did for colors. Blue (pun not intended) hurts my eyes and transparency doesn't look great with some apps open. Also, if you go to device encryption, because you changed colors, some foreground and background colors are now identical and I wasn't able to read the options... I think that screen was the one for if I wanted to ask for password when the device boots.
Also do you have a git for the source tree? I'm learning to build Android and am hoping to see how you are doing things?
Thanks again and keep it up!

I'm doing my mods on the precompiled factory rom. If you go to the Lineage OS thread, Vampirefo has a link to the device and vendor tree he created for his rom. I am considering having two versions of my rom for the Mini. A light theme (stock) and dark theme the one that is out now. Right now the rom is only in testing stage. I enjoy seeing your interest in learning how to do what I am doing, the more developers the better.

This is awesome thanks so much!! I use Windows on a daily basis but I do have a pretty good knowledge about Linux and have set up a build environment in for Android. These links should help me understand what I am missing. I am also happy to continue testing and give you feedback on this ROM as it is currently my daily driver.

New Rom out. It has the stock theme, other than that it is the same.. I haven't decided if I'm going to build two Roms or have the theme be a patch. Maintaining all the different variants of the Rom are getting to be very time and space consuming.

Strange question, but on the original stock rom, I started having issues with the Package Access Helper not working, while installing updates for Paypal, and just straight up trying to install Spotify, even the APK. I did a full factory reset, still did not work. I also installed the custom rom over at BLOX2.com, and the Package Access Helper still would stop working, even after clearing data/cache. I'm just curious if you know if your rom will fix that issue?

Good news I was able to get Android File Host to make the Life One X2 an official device. I have made a request for the Mini too. For now all the files will be under the Life One X2 device.
Updated rom: https://www.androidfilehost.com/?fid=673956719939824825
It includes the stock Calendar, Clock and Calculator apps. I changed the DPI to 441. Let me know if anyone has any problems with the Playstore. I know that there has been some requests for the stock Camera and file Manager apps. It's hard to please everybody so I added a patch section which may please some.

STOCK FIRMWARE INSTALLER: https://support.wikomobile.com/maj/Lenny5_OPE_V34.zip <-- if you brick your device.
Hey folks
This is just a brief explanation on how i built this ROM, a complete guide to building the rom may be published at a later point in time. For the Downloads, go to the Links section. The flashing guide will be focused on Lenny 5, but the image may work on other treble-enabled devices, too, so feel free to try and report if your device works with this build.
Build variant: arm-aonly-floss-su-userdebug
If there's interest in other build variants (specifically with microg and floss - fdroid, moz-nlp, openweatherprovider - implemented), ask me, i will do my best.
Build description:
I have an old Wiko Lenny 5 around here and wanted to use it as a Kodi Remote etc. at home, but didn't want to use their stock ROM. Also i wanted some freedom in using my device, specifically a rooted device and microg implementation. After trying to build TWRP with no success and the Wiko Build information being massively outdated i then focused on Generic System Images, as Lenny 5 is Treble-enabled. Big thanks to @phhusson for the whole lot of effort he put into building AOSP GSI's (and also clues towards building LineageOS GSI's). After having AOSP9 installed on it for some time, i got bored and tried to compile LineageOS using the patch-and-build system provided on phhusson's github. That worked just great on AOSP9, but failed to build a bootable LOS16 in the first place. So after some recherche, i stumbled across @AndyYan's thread, containing some LineageOS GSI's prebuilt and ready to use. These worked great on my phone, but as stated above, i wanted to customize my LineageOS even further, so i manually patched my build-tree with AndyYan's Lineage-Treble-Patches by doing what this build script does, tested and it booted (i guess it's mainly related to the SELinux Policies not being correctly built for LOS with only phh's treble-patches). So far so good.
Additionally, i implemented the MicroG services by cloning these prebuilts on github to the respective folder in the build tree and before the build executed
Code:
export WITH_SU=true
to include LineageOS's root system in the build. I adapted the treble_arm_afS.mk device config to not use phh's su and the device/lineage/floss.mk file to include
FDroid
FDroidPrivilegedExtension (which is being built from treble sources)
MicroG services (use Play Store Apps)
FakeStore (use Play Store Apps)
MozillaNlpBackend (MicroG Network Location backend)
NominatimNlpBackend (MicroG Network Location backend)
OpenWeatherMapWeatherProvider (for LineageOS Weather Provider)
You are then free to use no Playstore at all or i.e. Yalp Store to download Play Store Apps.
After downloading the Image you may need to Unpack it via 7-zip or another tool.
Flash the device:
To install this custom ROM on the Wiko Lenny 5, in your stock ROM go to Settings->Developer Options->OEM unlock->Enable. Also, in the Developer Options, make sure, ADB Debugging is active and, on prompt, accept debugging connections from your computer.
On your computer, enter Command Prompt and issue the following commands:
Code:
adb reboot bootloader
*wait for device reboot*
fastboot oem unlock [COLOR="Red"]<-- this will factory reset the device!!![/COLOR]
*press vol up on the phone to allow unlocking the bootloader, and wait for the phone to return to fastboot mode*
fastboot erase userdata
fastboot format cache
fastboot format system
fastboot flash system <path-to-the-downloaded-gsi>
*wait for each process to finish*
fastboot reboot
now, wait for the phone to reboot, it should, after some time, show you the usual LineageOS startup screen. Take your time to set up your phone. To make MicroG and FakeStore work properly, you will have to Go to Settings->Apps&Notifications->App-Permissions->Spoof package signature->Menu->Show System Apps and allow FakeStore to spoof Signature. Go to Settings->System->Advanced->MicroG Settings and add your Google account. Activate Device Registration. Then activate Google Cloud Messaging and Google SafetyNet, if you want to take advantage of those services. Inside the UnifiedNlp Settings choose MozillaNlp in the first, and NominatimNlp in the second setting.
Go back and choose "Self check", if required, if required, grant MicroG GmsCore the permission to spoof signature, this should make most of the boxes go "checked". If Phonesky shows errors about signature spoofing, this should normally be gone after a reboot of the phone (given you allowed FakeStore sig spoofing). Disable battery optimization and then reboot the phone.
Check back in MicroG Settings->Self check, if all the boxes have been checked. If not, most mandatory points are self-explanatory.
This Lineage ROM will not allow you to update to a newer version. I cannot guarantee continuous updates, but encourage you to try building LineageOS treble with the way explained above, yourselves. If enough interest is around, i will consider doing updated builds from time to time.
Update:
Today i compiled a recent source tree containing the 5th of October patches. I will try to keep up with updating the Image whenever security fixes are released. The download links below have been updated to the newest version. To update your phone without deleting the data on it (make sure you have adb debugging enabled), you can simply do
Code:
adb reboot bootloader
fastboot flash system <system-image.img>
fastboot reboot
and then give your phone some time to "update". it should boot normally without erasing your data.
Links:
ROM .7z [~430MB]
ROM .img (~1.1GB)
(version was compiled at 19th of October '19, containing the October 5th security fixes.)
Let me know if this works for you, too!
Cheers

Nice work
Nice work, I'll test the ROM later or tomorrow, also I like to see some development for this phone, also, It would be very nice to develop a custom recovery for it for better flashing experience and being able to flash gapps.
I have kinda workplace on my PC, I'm still wondering to build my first ROM but I think it will take lot of time.

Thanks. The custom recovery thing is a bit more difficult for treble devices, but i'd be happy to learn more from more experienced people.
I was not able to get TWRP running despite "successful" Custom recovery builds.
The build is quite straightforwards if you have some experience on compiling with linux. But you need around 200400Gigs of free space per build tree (lineage, aosp, ...). The most difficult thing for me was to alter the sources for inclusion of the packages i mentioned above, including microG. to build with opengapps, i expect, you'd use the same approach to include them in the build tree as with microG, just using the other packages and probably slightly customized CUSTOM_PACKAGES config. there is a k300 recovery out in the wild net. so there should be at least *some* possible way to port twrp for the k400, too.
about the time to build the rom: it took me about a day to sync sources and, using 2 cpus at 4gig's of java virtual memory, about 6 hours to compile the first round. after that, only compiling the changes made, it took me about another half an hour to recompile the changes. the editing process is marginal, if you know how to append to/remove from/patch the source files, the lineage4microg and treble rom-builder bash-scripts on github give you a pretty good insight in how to apply patches. also, from the dockerfiles you can get a list of all the dependencies your system needs to build the tree. i used these sorts of "tricks" to ensure my build runs well.
so far from me. i will try to find some free time in the future to put up some guide on how i built the rom as-is.
feel free to report if the rom works on your device!
best regards

The ROM works great but I'd like to see one like this with gapps to install on my device (freaking system image size), I've never used MicroG before and I don't know well how to use it.
Also, if you have the knowledge (I'm pretty sure you know more than me) we can investigate a way to create a TWRP version for K_400

Hi Hanthonious
ivelischt said:
If there's interest in other build variants (specifically with microg and floss - fdroid, moz-nlp, openweatherprovider - implemented), ask me, i will do my best.
Click to expand...
Click to collapse
as the microG variant requires some "special sauce", namely the ability to spoof signature as well as other small fixes in the source code, my source tree is a bit different from the "vanilla/gapps" source tree. thus, to build variants not containing microg, you can simply sync the lineage source tree and apply the additional phh treble sources&patches. *edit: next to phh's patches, you will also need AndyYan's patches; you can find information about it in the OP. given, i write a guide (which i still intend to, but this takes some time), the patching step will be explained more clearly* basically, it's one step less than compiling it with microg. at the moment i cannot afford enough disk space to create another work tree, which is why i "can't promise" other build variants, until this issue is gone. which may be tomorrow or in a year. maybe you can find a gapps-version of treble-lineage 16 here in the xda boards. otherwise you will have to wait, or try to build it yourself. also, you might be interested in @AndyYan's lineage version, which is vanilla (no gapps or microg).
i would guess that the system image will not grow excessive just by including opengapps, but i may be wrong. i think that you'd possibly would have to choose a "non-complete" opengapps-package, to make it fit.
to quickly summarize what microg does is, that it spoofs its signature to make your phone think that you have the real Google Services Framework, Google Cloud Messaging, etc. services installed. this makes apps, which depend on these services, work even though you don't really "have" them. additionally, microg establishes an "essential" communication between itself and the real google services to allow you to use google services despite having all their bloatware.
to round this up, you have fakestore which spoofs existence of Google Play Store for those apps and games, which specifically check for GPS's existence (Phonesky app).
i think this should quite generally point out, what microg is for (an api which connects you to google, whilst only handing out information, which is crucial to keep a specific connection alive)
you can then use i.e. Aurora Store to download and update your preferred playstore apps. i tell you this specifically, as i hope that, using it right, microg might be able to give you a "fully stocked" phone experience, whilst keeping most of your data secure and your phone unbloated by google's app-hoard.
if you follow the instructions in the OP on how to fully enable microG, this might be a very handy solution for you, too, so maybe, you want to give it a chance.
to point out my issues with twrp (as far as i can tell using my little experience): twrp is device specific. which means, you need a vendor tree and you need to include it whilst building, so twrp can compile against it. now, treble is a way of excluding your device specific vendor tree from the build altogether (your system image basically doesnt contain the vendor files in a "folder" (/vendor), but in a seperate partition. this partition is "simply" beeing symlinked to from your system partition. this way you will never need to build vendor-specific sources but android builds against standardised "api's" which are being "serviced" by treble-enabled phone's vendor-files (lying at the vendor-partition). this makes building aosp and/or lineage, etc. easier as you can build one variant per architecture, which fits all treble enabled phones of that architecture (arm/64/binder32/64,a/ab,...). this is, very basically said, what is called a HAL (hardware abstraction layer) on a desktop computer.
but at the same time it's much more difficult to find vendor sources for those phones, as there is no more need at all for manufacturers to make these sources publich (as far as i understand it). as a matter of fact, you may not need these vendor sources for modern aosp (8.1+), which really is a grace!! but twrp doesn't seem to work when compiled against treble trees.
i even managed to compile a kernel which is mentioned at the wikogeek site for the lenny 5. i tried to include that kernel when compiling the recovery image but even that did not work out. as i am no experienced programmer (especially not in the high languages), i will not be the person to ask when it comes to finding out what bugs and how to circumvent it.
there is a little light at the end of the tunnel, though. as far as i understand it, treble-phones come with mostly generic kernels, which *could* make it easier to find a way to build a kernel/boot/recovery image in a similar fashion we build the gsi (generic system image) with. additionally, if there is some effort on it, i imagine, that it would be possible to generally modify twrp in a way so it's able to build against treble source trees with missing vendor source. this would enable twrp to run on virtually any phone which is treble enabled and there would be few to no need to port it for each device, specifically. maybe there would then be versions as in the treble gsi's (arm/64,a/b,...) as well as build variants for alternative display sizes etc.
but i wouldn't even know where to start...
i hope i was able to answer your questions. if you decide to stick with the variant in the OP, you should consider downloading and installing the most recent updated build.
best regards

Problems I found in the rom and if there is a way to solve them
Yo,
I wanted to point out the problems I found in the rom and if there is a way to solve
These are the problems I encountered:
1: *THE MOST IMPORTANT*
I can't pass the safetynet test, I researched a lot and I still couldn't solve
When I try to pass the safetynet test on magisk it gives "safetynet API Error"
When I try to do the test with the "SafetyNet Helper Sample" app it gives "SafetyNet request: success
Response validation: fail
Error Msg:
ApException [17]: API: SafetyNet .API is not
available on this device. Connection failed with:
ConnectionResult {statusCode = SERVICE_INVALID,
resolution = null, message = null}
And the "SafetyNet Test" app gives me "fail (Google Play services not available)"
I am aware of the new problem with the safetynet:
(sometimes people are still able to pass the test probably because it is still in maintenance or something)
https :// www . androidpolice . com /2020/03/11/safetynet-improvements-kill-magisk-hide
https :// twitter . com /topjohnwu/status/1237656703929180160
https :// twitter . com /topjohnwu/status/1238514375150850048
https :// twitter . com /topjohnwu/status/1237830555523149824
But even so I should be able to run the test even if it give both negative should run instead of showing those errors
2: The contacts I had on the SIM card and Google account do not appear in the contacts.
So I went on WhatsApp to save the ones I wanted to save, but after a few days and a few restarts the contacts are still saved, but on WhatsApp it shows that they are not saved even appearing in the contacts, to appear again saved on WhatsApp, I have to save them all again
3: Cant login in Clash Royale with google play games account, can i flash the rom and gapps to work or the microg and google play services will create some conflict, is there a way to unninstall microg completly and reflash the rom without microg and flash gapps?
4: Error when login in pokemon go: unable to authenticate, I researched it and it seems to be because the safetynet is negative but I can't even run the test (only after I became aware of the new safetynet problem) even with this new problem I would like to try to run the test to see if it passed since some people still are successfully passing the test
5: in the microg settings in self-check an option is not checked in the box "UnifiedNlp do not have location to test geocoder" I already researched to see if it solved something but I couldn't
edit: I solved it using the "Apple WI-FI" backend instead of the "Déjà Vu Location Service"
BUT NOW ITS GIVE ME AN UNCHECKED BOX
"Network-based location enabled:
you either disabled network-based location
(in system settings) or the system is not
supported"
6: some times in the time widget just appear "loading widget..."
and these are all the problems that I encountered, pls help me
solving these problems, thx!:good:
sorry for some mistakes i translated from portuguese to english with google translator and my knowledge of english

CooperTUGA, thanks for writing. And I want to apologize for letting you wait for so long. In fact, at the moment i do not actively develop this ROM (due to data loss on my virtual machine).
Anyways, i will try to address your issues as good as i can, though i must admit, none of these issues happened on my device.
ad 1: The only thing that comes to my mind is, that something went wrong when registering your device with the Android-ID. (see OP activation instructions). The SafetyNet-API itself should be working, atleast I had no similar issues (after Registering the device it takes some time - around 5 minutes - for Android to reflect the registered state).
But if someone happened to have this issue and knows another solution, you are welcome to tell!
ad 2: Does it help when you try to import the Files from the SIM card? As for Google contacts, it is - from my POV - stringent, that, if the SafetyNet API doesn't work properly, you will be unable to access Google Services (as Google Contacts) which would explain the missing Google Contacts.
ad 3: GApps and microG are two different things. GApps install a version (open-source fork, contains proprietary binaries) of the Official Google Apps, that is, they provide full functionality towards google services, provided you registered your device correctly.
microG is a pure Open Source fork of that, providing but the Framework with which Google Apps can be run. It does not provide Google Apps (like PlayStore etc.) by itself but merely allows them to run, given the configuration is right. This microG-ROM is not built to work with GoogleApps like PlayStore, but instead relies on the microG Services to get Apps, providing same or similar services, running (like Aurora Store etc.). To address your question, it is possible, to change the source code which was used to build this ROM, so it builds with Gapps or completely free of any such services, in fact it would mean to exclude certain patches, but such projects (Treble-enabled) are covered by others and because of above stated reasons i will not be able to provide such in near future.
Short but clear: No, there is no way to "uninstall" microG as it is built together with the ROM and the source used was especially prepared to use microG. But if configured right, you should be able to use your Google-Account in combination with Google-Services-Apps or Games despite using microG.
ad 4: See above. If everything's configured right, you should be able to play Pokemon GO, although i don't use any of these Apps (Clash Royale, Pokemon GO, WhatsApp). I never encountered any Problems along using Google Apps with this ROM.
ad 5: Well, the error says it all. I have Mozilla Location Service installed, which works like a charm. Maybe try this one? You can get it from FDroid, search for "MozillaNlpBackend" and see if it helps to sort this out? This works for me, after all.
ad6: as this is very unspecific, i cannot really tell what's the problem, but i would guess it has to do with the SafetyNet API not doing what it should or even the Location Backend not reporting position in time...
Did you clean your cache and data partitions while installing this ROM? I really am not sure what could create the behaviour you describe. Maybe there was a change in the SafetyNet/Device Certification process since this ROM-Build, maybe theres someone in those boards who could answer this, but i unfortunately can't...
I'm sorry that i cant give you more positive news, but hopefully it helps you in orienting what some common problems could be caused by.
Let me know about your success in trying to get the ROM working.
Best regards and greetings to portugal!

additionally: if you are interested in porting the Lineage Source for GSI/Lenny 5, you might be interested in this Thread: https://forum.xda-developers.com/android/help/how-to-root-wiko-lenny-5-t3819469
specifically, i wrote a guide there on how to build Android/Lineage Source for Treble devices. Maybe this helps you in getting your own build environment, enabling you to build to your disguise.

[ROM][UNOFFICIAL][SUNFISH][A11] LineageOS 18.1

I'm not a fan of Android 12's Material You, i.e. dull color schemes, ginormous headers and copious amounts of whitespace. Screens got bigger over time, but information density is getting lower and lower. It's crazy. Anyway, I'll spare you the rant.
As the LineageOS project stopped publishing builds for LineageOS 18.1, but they continue to patch their 18.1-branch with Android's monthly security updates, I decided to start building it myself following the instructions here.
You can download the builds here:
LineageOS 18.1 for Pixel 4a (sunfish) - Browse Files at SourceForge.net
Unofficial builds for those who wish to stay on 18.1 a bit longer.
sourceforge.net
I usually publish an update every month.
Additional tweaks
Default maximum lockscreen password length of 64 characters (instead of 16) [more info]
FirmwareIt's probably best to run the latest Android 11 firmware, since this is Android 11. You can download the last official Android 11 factory image from Google and flash it from fastboot mode (your data will be erased).
Clean install
Download the latest lineage-18.1-xxxxxxxx-UNOFFICIAL-sunfish-boot.img and lineage-18.1-xxxxxxxx-UNOFFICIAL-sunfish.zip from aforementioned link
Boot to bootloader a.k.a. fastboot
Flash the boot image with this command (replace filename with actual filename):
fastboot flash boot lineage-18.1-xxxxxxxx-UNOFFICIAL-sunfish-boot.img
Boot to recovery
Factory reset > Format data/factory reset > confirm (your data will be erased)
Apply update > Apply from ADB
Sideload the ROM with this command (replace filename with actual filename):
adb sideload lineage-18.1-xxxxxxxx-UNOFFICIAL-sunfish.zip
(If it asks "Signature verification failed. Install anyway?" answer Yes)
Optionally flash Gapps or anything else:
Advanced > Reboot to recovery
Run adb sideload with your zip
Reboot system now
UpdatingUpdates are delivered through the built-in updater (Settings > System > Updater).
If you use Magisk, deny the Updater's request to reboot at the end of the update process, open Magisk, tap Install and then "Install to Inactive Slot (After OTA)". Tap reboot after the process completes.
Migrating from last official LineageOS 18.1 buildSo it turns out builds are signed with a secret cryptographic key and when you install an update it has to have the same cryptographic signature or bad things will happen. This means you can't directly update from the last official build (signed by the LineageOS team) to my build (signed by me).
The solution: build and install (as an update a.k.a. dirty flash) a so called "migration build", which "resets the keys on all packages at every boot." I guess after booting into this build once, you can just update to the regular build using the updater (the LineageOS wiki is very concise on this topic and doesn't explain much).
You can download the migration build and boot image from the aforementioned link, they are marked MIGRATION instead of UNOFFICIAL. Don't run this build any longer than necessary, it's a security risk by its very nature.
When I tried this migration, my system wouldn't boot (stuck on boot logo). ADB worked and I could see in dmesg or logcat that, among other errors, SystemUI failed to start. Was it because I didn't reflash Gapps? But I never reflashed Gapps when using LineageOS' builtin updater...
Later I did some testing. I did a clean install of the latest official build, then my migration build, then my normal build, all was fine. Then I did a clean install of the latest official build WITH Gapps, then flashed the migration build WITHOUT Gapps, and the system booted up just fine. Huh? Then I flashed my normal build DIRECTLY over the latest official build, without migration build in between, and all was STILL FINE! So uhm... what's happening, how does this signing work and when does it become a problem? I have no clue.
If you decide to try the migration route, make sure to backup any data you don't want to lose and let us know how it went!

GcamYou can just install it from the Play Store. There are a few bugs:
In photo mode, slide up to record video doesn't work
Motion Photos doesn't work
It doesn't scan QR codes without Google Lens
App versions without Material YouIf, like me, you try to avoid Material You like the plague, here's a list of the last versions of Google apps that I use(d) that don't have Material You. Note that LineageOS includes its own versions of some of them and all of them are optional anyway. You can find them on e.g. APKMirror.

Translate 6.24.0.02
Is it wise to run older software? You decide. In an ideal world security updates and bug fixes would be separate from UI and "we decided you don't need this functionality so we removed it" updates. I've long ago stopped regularly updating my apps (i.e. turned off automatic updates) because I like to be able to trust my device will look & work the same tomorrow as it did today.

P.S. After you've installed the regular 20220815 build, the updater will keep showing an August 16 update which is actually the build you're already running. This is because I had to move the timestamp one day forward in order to enable updating from the MIGRATION build, which was also build on 20220815 and wouldn't see the regular 20220815 build as an update otherwise. This will be remedied with the next update I publish.

The September update is now live.

Been using this for several days now without a hiccup , fast ,,smooth, and google proofed, Thanks!!

Thanks for keeping LOS 18.1 alive with these security updates. I recently upgraded to 19.1 to try it out for a few months but I just couldn't get used to or appreciate the new UI. With every app update they also make it more like A12 and it just wasn't working for me.
Just installed your September update and all is well so far.

The October update is live!
A little background: I'm building this ROM on a Google Cloud Compute Engine instance, which is a virtual computer (also called virtual machine or VM) running in a Google data center. To keep the VM around is very costly, as it uses 300 GB of SSD storage which doesn't come cheap. So I create a new VM every month and dismantle it afterwards. This means I have to set up the build environment from scratch every time, which consists of a lot of steps. So from the beginning, I've put most of those steps in a Bash shell script (the VM runs Ubuntu 20.04) to speed things up drastically.
Last week I added some code that generates the updater.json file (that's read by your phone when it checks for updates) which I had been creating by hand before. I also added code to automatically upload the build to SourceForge. So yesterday all I had to do was create the VM, upload the script and run it. Six hours later, your phone was able to download the update without any further intervention on my part.
What can I say, the geek in me is very happy

Hi, I thank you for your work. Would you know if I can install microg without magisk, maybe via nanodroid or similar while maintaining OTA updates?

I have no experience with that. I assume you would have to apply the signature spoofing patch and install microG before booting from the updated system partition. So after installing the OTA update boot into recovery and do this?

Hello ! How to you push the google apps on this one ?
I'd like to get a pico gapp installed to get some game running

It's in the instructions in the first post, after flashing the ROM:
Optionally flash Gapps or anything else:
Advanced > Reboot to recovery
Run adb sideload with your zip
I'm using NikGapps Core myself.
This only works if you do it before first boot by the way, as far as I know you can't put Gapps on an installation you're already using.

Hi! Do you know if this will retain microg if I dirty-flash it on top of a lineage.microg.org build (the last official release) using your MIGRATION build? If you're not sure I'll back up my stuff and give it a shot and report back Thanks a lot for your your work!

Well... I don't think that would work, since this ROM doesn't include microg and the needed signature spoofing, so my guess would be you'll just loose that—if the migration works at all. Let me know what your findings are though!

Here is what I found, in case it helps someone: flashing the migrate ROM and then the latest proper ROM works perfectly, however I did lose microg, system f-droid, etc, and anything which is in the lineage.microg.org build but not in this one.
Now since you are building monthly ROMs, would you consider applying the signature spoofing patch to your builds? This would make it easy for those who want to run microg instead of google play framework/gapps. As far as I understand it you just need to apply this patch with `cd android_frameworks_base; patch -p1 -i /path/to/android_frameworks_base-R.patch`. Thanks again for your efforts

I'm open to consider this, but as I somewhat but not fully grasp the security implications of enabling signature spoofing, and not everyone might want to have this enabled by default, it would have to be a toggle in Developer Options and disabled by default, or I would produce a separate build with the patch applied.
If you could find a patch for me that implements the toggle in Developer Options, that would be great. As I researched it a bit I read that some ROMs have this.
Interesting that the migration worked, by the way!

Some more thoughts on this: it seems with signature spoofing enabled on the ROM, an app still has to ask for the permission to spoof its signature, so for advanced users like us who know what we're doing, I guess that's good enough. I'll have to read up on this a bit more though. I know the LineageOS devs are against implementing it but most everyone else says it's actually not that big of a security risk.

I just reply to show you my gratitude for maintain LoS 18. I updated to 19 two weeks ago and I was literally suffering with the system theme. IDK what they were thinking but it was terrible. Also for me, on 4a, was having lag: An example is when I shuffle songs on Musicolet, they take a good while to update the information (song name, basically) while with 18 it updates as soon as I press next.
BTW, can you recommend me a good KERNEL? Thanks!
