[GUIDE][COMPLETE] Android ROM Development From Source To End

Hello Everyone....:D:D Today I will present you all the ultimate guide for ROM development starting from Source to End. This guide will be applicable to all devices. So lets Start :D What is Android? :rolleyes: Android is an...

When I started ROM builds, my best source for learning were the instructions to build LOS for a supported device.
[General Questions and Answers] Ferchurito:
Thanks a lot for answering :D

But i dont understand what you mention about building lineage os builds for supported device. A supported device for what? officially supported by lineage?

I own a samsung tab 3 8.0 and wanted to develop a rom based off lineage os 15

Once again, thanks for answering and providing that guide :D

Bit of a "conceptual" question. 3 questions.

I have a BRILLIANT paid live wallpaper that I have been using since about Gingerbread. It was last updated in 2017 and probably dropped from the PlayStore not too long after that. I have since been restoring the app from backups, as its no longer available from the PlayStore.

My questions:

What is the general understanding regarding apps that have been deserted. eg Can I install from a backup since it can not be validated as being paid for by the Playstore?

Movies etc have something like 25 years before they automatically move into the public domain (unless rights are asserted beyond that period). Is there a similar, possibly shorter period for apps from the playstore?

I did a search online to see if the dev was active ANYWHERE on the net, and I stumbled upon a questionable APK. It was different (MD5) to the one I paid for on the playstore. I checked on two APK malware checkers, and one said all was OK, but another actually found an issue of concern.

3. What is the best (multiple) online options used to check an APK for malware?

I used:

https://www.virustotal.com/gui/home/upload this found 1 issue

https://metadefender.opswat.com/ this found nothing

OK I got it to work. For posterity, I found this guy's video:

The APN settings on the carrier's (KDDI au) official site DON'T WORK. But this guy found some other settings that do. How ridiculous it is that the carrier provides the wrong information?
[General Questions and Answers] Ferchurito:
ok thanks. So then I should starts practicing my developing an android emulator for windows and then start looking into another guides, right?
[General Questions and Answers] DiamondJohn:
Not necessarily. I simply gave the emulator as an example in case your phone is not supported on any other ROM. LOS has explicit instructions for each supported device. That example was simply the first and the most vanilla one I came across in a search.

Search github for your device. If no one else has pre-built your device-vendor-kernel sources, then that is going to be your road-block, when learning/starting to build. Generally speaking, the two most common build types (ie ROMs) are LOS (or LOS based) or AOSP based, and the device tree will usually be specific to the ROM.
[General Questions and Answers] Ninjagar:
I wanted to build ROMS, but having listened the requirements of a high end system, i eventually dropped the idea.

But recently I came up with a question : Is it possible to edit the codes of my current custom ROM and make some customizations; the same way you would build a ROM?

Any help would be appreciated ☺️,

Thanks.
[General Questions and Answers] DiamondJohn:
Magisk is often used to modify system components in a running ROM.

Can i Use that for modifying anything, like when building a ROM?
[General Questions and Answers] DiamondJohn:
No.

so i just found my old moto z2 force and i was wanting to get it working but it does not turn on even after charging for a day it goes to a circle with the thunder bolt symbol then it turns off

also a led at the top turns on for one sec

also i tried rooting it a while back but was not successful the farthest i got was a unlocking of the boot loader

i need help

my Samsung galaxy j7 core would suddenly freeze es its screen and stay unresponsive for what seems like no fixed amount of time before blacking out, now if i try to long press the power button in order to wake it up it wouldn't respond instead what would only work with it is force reboot (power+vol down).

everything on my phones was official. no sketchy apps installed nothing to pin down this newfound perturbance to. such occurrences would strike untimely, they dont seem to be triggered by a specific task that i do they just happen whenever, sometimes even if my phone is idle/not being used. i have tried doing a factory reset-tried stress testing-tried clearing cache partition. nothing seems to stop this although its worth mentioning that the factory reset seems to have lessened the rate at which the freezes would happen. any ideas as to what might be causing this?

Here's a good one for somebody looking for a challenge:

I have a $3000 automotive scan tool I want to root and add Google play services to. It is an auto maxisys ms906bt.

There is ZERO support for this thing in the community.

I have the technical know how to work with somebody that is willing to take on the challenge.

Things that need to be known:

The Autel ms906bt runs a Samsung exynos 5260 processor on Android 4.4.2 kit-kat.

It is a proprietary front end installed that has limited ability to launch the preinstalled applications.

The machine is subscription based with an annual fee of $700 to keep it active and updated with the latest automotive manufacturer databases.

It is important that any modification can not be detected by Autel, though I'm not sure to what extent or how discriminately they monitor these systems.

It is important to be able to restore the machine to it's as shipped state to ensure there's no chance to brick it.

I want to first find a way to make a complete ROM backup that will include all the data on the machine as well as a firmware backup.

As far as I know there is no key combination to enter a download mode or recovery mode.

I have read about restoring the factory firmware that seemed to involve booting the machine with a file on an SD card and it seems it will boot from the card to run a firmware update of some sort.

Anyway, for anybody interested in taking on this challenge, please pm me.

The machine I have on hand is fresh out of the box with no updates applied to it so as to retain a baseline for a backup.

I really want to turn this into a fully functioning Android tablet but I definitely don't want to turn it into a $3000 paper weight and I don't know enough about rooting and installing recoveries and dumping firmwares to confidently try and work this out myself. My technical extent involves following guides that wonderful people create to root and customize my devices but as I said there is (understandably) zero zero zero info on this particular device.
[General Questions and Answers] DiamondJohn:
Yes.

But are you serious? I could also type up the whole of War and Peace. Do the research or start a specific thread.

As a single simple starting point, Magisk modules are loaded in the post data mount (at their earliest), meaning the IO drivers are loaded, which means the kernel is loaded, which means the ROM has started to load, before you have a chance to replace it.

By "SCAN TOOL' what does it actually do? OK did a serach and its labelled as "OBD2 Bi-Directional Bluetooth Diagnostic Scanner"

I use ODBII via Bluetooth, on my standard android phone using a $15 OBDII to bluetooth adapter, and free software (time limited) from the playstore to read/display/graph live engine values or to read and reset error codes.

It should be something like to say, "Don't warn to me if something dangerous is around..." Shut up the messenger and the message will be silenced. If I was not clear enough, and you still can take the risk, disable your antivirus from your browser, and after you still need to disable the Windows Defender to allow the app being executed.
[General Questions and Answers] geraldnemo:
Hi all. New here, just had some hopefully basic questions. I have a Sprint LG V30+ (LS998) and I'm hoping to switch carriers before the end of the year - T-Mobile, US Cellular, I'm not very picky. Sprint's V30 is annoyingly locked down. My questions:

1) If all I really want is to be able to use the phone on different carriers, is there anything I need to do beyond following the instructions here? https://xdaforums.com/t/frankenstein-phone-using-lgup-for-crossflashing.3780969/post-76510671

2) Anything to keep in mind regarding choosing a carrier? I dunno the first thing about carriers and bands and the like, so any things to look out for would be appreciated.

Thanks!
[General Questions and Answers] Droidriven:
The thread that you linked in your post has nothing to do with switching carriers. The thread you linked is a guide to convert your device's software to another device's software. I don't think that guide will help you.

Switching carriers involves SIM/carrier unlocking the device first, then activating the device with a SIM from the carrier that you want to switch to. You may or may not have to flash a modem from another device like yours that is compatible with the network that you are switching to in order to make your radio/modem work with the new network.
[General Questions and Answers] geraldnemo:
It's a moot point now. I had the opportunity for a free upgrade and decided to get a Pixel 6. It's probably an improvement in most regards, but the V30 worked perfectly fine for me and I didn't want to change phones unless absolutely necessary.

The issue was that the Sprint V30 is a specific model (LS998) locked to Sprint's network (which is obviously going kaput early next year) versus others (US998 et al) that aren't. The LS998 hardware is identical to other models, can use the same cell bands, etc. It's just software-locked to Sprint and can't be ported to other networks. Me, not knowing the ins and outs of the smartphone ecosystem, didn't know if the above (OS flash? firmware flash?) guide was all I needed to do, if I needed to be aware of other issues, etc. You mentioned flashing the modem; is that often how such network locks are done?

Asa;kdfja;sf But again, it's a moot point now. Sorry to have wasted your time.

Hi, can anyone help me ?

I have problem with my phone (Lenovo K520), MTP and ADB not working when connected to pc. I tried with different type-c cable and pc, device manager doesn't detect any new device. But if i connect my phone in fastboot or EDL mode, pc can detect and recognize my phone. And sometime MTP / ADB works after reboot from fastboot mode, but when i try to unplug and plug the usb cable again, MTP / ADB not working again.

I did try to change my PCB port too, but still not solve it :( i'm out of idea
[General Questions and Answers] DiamondJohn:
Another thing to check is that you are running the latest ADB Drivers on your PC.

Personally, I use ADB over WiFI, and FTP to transfer files, using the file manager MiX.
[General Questions and Answers] rna98:
Yes i have installed latest ADB drivers. I wanted to use MTP for data transfer (but yeah i use FTP too for transfering small size files). What i do not understand is why fastboot and EDL mode is working fine while MTP or ADB not working. The phone only charging when connected to pc (when the phone is in system or TWRP) with no any sign of new device connected, but if i switch to fastboot mode or EDL 9008, the pc can detect and recognize the phone.

Sometime MTP and ADB works only if i reboot the phone (still connected to pc) from fastboot mode to TWRP or system, but its really rare :(

Hi. I dropped my phone this morning (Samsung Galaxy A70), and the screen went black. I've bought a new one, but I didn't have backup of my images. Is there any working software, that will allow me to access my phone, and retrieve the image-files?

Thanks
[General Questions and Answers] Droidriven:
Did you have USB debugging enabled in developer options in the device's system settings?

Gotta be able to unlock the screen for one thing, this tends to be a major roadblock because the device will not connect to PC while booted into system if you can't unlock the screen. You may have gotten lucky and only damaged the display itself but touch may still work, if you didn't have a pin/password set on your lockscreen, you may be able to unlock the screen with a simple swipe. If you had a pin/password, you may be able to connect a keyboard and manually enter the pin/password to unlock the screen. If you had a pattern lock, you can try experimenting touching/swiping the screen where you think the pattern is, you might get lucky.

If you also damaged the touchscreen, you can try using TWRP custom recovery if you had USB debugging enabled and if there is a TWRP that is compatible with your device.

If none of these options are available to you, you can try finding a tech shop that has the equipment and experience to pull your data from the chip itself.
[General Questions and Answers] Droidriven:
Flashing modem software is sometimes necessary when switching carriers/regions to make your radio compatible with the carrier network or region where it will be used. But most importantly, a device must be unlocked to be used on a carrier other than the one it was manufactured to be used on. Whether the device is CDMA or GSM may also come into play in some cases.
[General Questions and Answers] Full House:
hi guys do you know if there is a module for 5G only?
[General Questions and Answers] SubwayChamp:
Because ADB needs different drivers than fastboot.

I would recommend that you start from scratch, sometimes we install unnecessary drivers or some self-driver-installer does this for us, too many drivers that we don't need or expect to use.

Not sure if it makes a difference deleting your ADB keys from its path onto your PC and specially if it is a second-hand device from there too.

Installing the LMSA tool, the proper drivers could be installed.
[General Questions and Answers] fonzacus:
how do i activate these long swipe gestures (ive set to flashlight)? im currently on havoc (and often see these) vanilla, nik, and magisk canary but cant seem to trigger these
[General Questions and Answers] rna98:
I already tried uninstalling and installing the ADB driver again with different source in different computer (Win 7 & 10), and the result is still the same. Right now i wanted to fix the MTP, because not all PC have wifi peripheral so it needs cable (which i already tried with different cable too) to transfer data.

i'll try use LMSA tool, thank you so much for the suggestion, i apologize for my bad english.
[General Questions and Answers] Droidriven:
On the bottom of the page in your screenshot, it says you have to be on Homescreen and you swipe the bottom of your screen So, by that example, your setting for flashlight is set to vertical left and right swipe, to activate, starting from the very bottom of the screen, swipe up on the left or right side of your screen.
[General Questions and Answers] fonzacus:
still couldnt trigger it anywhere. that note looks like its homescreen only, but still should apply anywhere. on the homescreen gestures are usually given a top priority to app menu, statusbar and recent apps

seems like a brand new feature not many people know of yet, i dont think ive seen people talk about it or at least make a feature vid yet

Hi there,

Hope you are fine. I am using Mi Note 10 Lite 128/6 Nebula. I am using current MIUI 12.5.4 stock ROM and stock ROM really really is buggy and many features is not working like Cleaner. Cleaner is not cleaning cache of any apps. I crrated a thread about this issue on Xiaomi official forum but nobody care.

In my country changing ROM voids guarantee and i am waiting until August 2022 for changing ROM. But before this i have some questions.

Mt device supports 64MP Ultra, high resolution video recording like 1080P and 4K, track moving video recording,macro and etc. My real question is if i change my ROM from stock to the ASOP or another ROMs will i lose these camera features? If yes what are the ways of using these features in ASOP or other ROMs?

I need your experiences and help about this issue. Any help would be appreciated.

Thanks in advance.

Kind Regards,

Happy new year.

If anyone knows from a direct experience, in the meantime you could search for the camera app based on GCAM, it has multiple adaptation for multiple devices, in the thread for your device (Toco) probably they can cover your doubts https://xdaforums.com/t/port-7-3-toco-gcam-for-mi-note-10-lite.4132275/ the features of a GCAM camera app ported for one model may vary with reference to the ported for other models.

As per the guarantee, if you do the things carefully, and you know what you are doing you can unlock bootloader, install the custom ROM of your preference and in case you need to claim a guarantee you can return your Xiaomi to its original state at any time.
[General Questions and Answers] pol-der:
Thanks for the reply. My friend tried Gcam for toco and it doesn't support all stock Camera's capabilities like 1080P, 4K, track moving and Slowmotion features. I had Samsung Galaxy Note 4 Exynos and i know how to install custom ROM on that but i have zero idea how to install custom ROM on my new device toco.
[General Questions and Answers] DiamondJohn:
I dont know your device, however, a few years back I was thinking of getting a sony compact phone that was legendary for its cameras' low light capture abilities. These abilities were heavily software driven with proprietary code. As soon as you unlocked the bootloader, these abilities were gone. No 3rd party app could duplicate their special proprietary code. Your camera abilities may have similar restrictions, or even, its functionality is so unique and/or specific, that 3rd party apps dont take the time to support them.

Hello everyone! I have a couple of questions that I hope someone can help me with:

I bought a Huawei Nova 8 (ANG-LX2) and I see virtually no reference of it anywhere. Does anyone know if it's perhaps known differently elsewhere? The forums don't have a section for it either, so it makes me strongly believe that it has a different name everywhere else. Can someone help out?

Said phone had EMUI 12 preinstalled on it, obviously without GMS. Is there any way to roll back to EMUI 10? I've been without Google apps for half a year and I can't get used to it since I REALLY make use of it (I'm a teacher).

Is there (otherwise) any way of installing and using google apps without GSpace, VMOS, or any similar apps? Those are loaded with adds and, more importantly, gmail doesn't seem to load mail properly until I actually open the app and leave it open at all times (no notifications or anything, it seems like it only scans for new emails if I actually bring up the gmail app on the screen, not even if it's open in the background).

I'm completely lost on these topics, but I'm a very fast learner and just a push to the right direction would be super helpful. Thanks in advance for any help I may receive!
[General Questions and Answers] SubwayChamp:
From what I know, unfortunately, GCAM is the most, and it's way far from the features of a stock (OEM) camera be Samsung. Xiaomi, etc.

The things changed a little from those days, the GN4 Exynos variant didn't need the bootloader to be unlocked and had good ROMs from Dr.Ketan, In Xiaomi you need to bind your Mi account to your device and wait some days to unlock it (maybe a week), from there it's not so difficult following the guide for a specific ROM, anyway if the camera it's a must for you then better stay in a stock Xiaomi ROM, also the Miui.eu ROMs are a good alternative to a Miui stock ROM, they're debloated and faster compared with…https://xiaomi.eu/community/threads/miui-12-0-12-1-12-2-12-5-stable-release.56191/

But be sure what you are doing, don't risk your guarantee until you can deal safe with it.
