Security question about custom roms - Android Q&A, Help & Troubleshooting

Hello,im new at this forum und want to learn something.I've been using stock roms until recently.But ı recently started to install new custom roms on my phone and ı had an important question.How safe are these custom roms? Is there any possibility of stealing credit card informations or credentials with custom roms?If the answer is yes,how can we know if there is such a thing?(Stealing informations or credentials with custom rom)How can we understand the custom roms containing these types of software?I would be very happy if you could answer my question.
Thank you very much.

If I could understand you well, meaning the rom will be stealing your information. Your stock rom even steal your information which you are not aware. Depends on the apps running on your device. Google apps are number one. Other device brands also collect information from using their device which they claim is for statistical purposes, which the user is not aware. Every rom is not safe ones you are online.

Redmi note 3 ROM Uploaders please read!
I have been flashing stock roms for a few years now and I have noticed with this device that many of the uploaders are not providing all the details just some of the following:
Detailed description
Is bootloader to be unlocked first
Is a custom recovery needed
Full instructions on how to install
Screenshots
bug list
Which Gapps package to use
Please provide all (the above) the neccessary information so we can make the decision is this ROM good for us to flash on our phones.
There needs to be a template for ROM postings so it can be easy for the end users. (Forum moderators will know the formula so I ask ye guys to sticky a template)
Thank you (ordered mine 3 days ago come on gearbest I wants my precioussss)

First thing, its not stock rom, its custom rom.
Second, the developers are not being paid, and thus whatever thay are doing, just accept it and ask for help, not post post like this to command them to list things that are obviously common sense.
1. CM13 Nightly, this 2 words give enough description, what more do you need. In this time, if you don't know what cm13 is then don't buy an android. Nightly means that there are still bugs, both minor and major, and sometimes it means that there are some things broken too. The devs also list whats working or whats not. They can't list every single thing.
2. You are flashing custom rom, thus you must have custom recovery like twrp, in order to install it you must first unlock your bootloader. If you have custom recovery, then it doesn't matter whether your bootloader is unlocked or not.
3. Did you really just asked if custom recovery is needed, are you a fool or what. Let me make this clear, if you want to flash a rom, how are you supports to so without a custom recovery. Stock recovery can't flash rom, neither it can make backup, restore backup and lots of things. The most basic thing to do even before rooting is to flash a custom recovery. Without custom recovery you can't even properly root. Well you can root with some apps, but custom recovery makes it easier, just download supersu and flash it with recovery.
4. Whats there to know. If you have custom recovery, then first create a backup. Almost every thread that i have ever read on xda, it is stated every where to always make a backup before doing anything, even rooting. Then, wipe data cache dalvik system, and then flash the zip file. After that if you wish flash the gapps.
5. What do you need screenshot for. Haven't you ever saw CM13 or ressurection remix. Just google it. they are not obliged to post it here for your convenience.
6. They do provide bugs, whats working or what not. And its not like they know a bug and haven't told other about it. They, in most cases don't know how many bugs there are, the other users tell them the bugs and they fix it.
7. Why would they tell you which gapps package to use. Do they work for google. Anyway, just google gapps, your rom version, ie cm12 or cm13, you mob architecture, arm64 or arm32 or whatever, and just download it. There is no geek stuff behind it that you can't do it yourself.
And finally, you are not paying them do anything, they are doing this because they like doing this. They are not even getting paid by this. So you ordering them to these things which you can do yourself after some googling and using your brain a bit, is just unjust. Just accept what they are doing, thank them, enjoy the rom, and report the bugs, etc etc, and have fun.

2. Some modified roms can be ran from the stock recovery.
3. You are a fool this is information for the end user I will slap you with a fresh wet fish!
4. Information is key.
5. Screenshots show people what they are flashing very helpful to the end user

If you are using a 32bit windows, then do you ask others which application to install, 32bit or 64bit. Man you are a joke, it's not information, its common sense. information is which partition is used for what purpose. How to restore imei. How to unlock lte band, not which gapps to flash. And there is no stock recovery out ther which flash custom roms. The only roms you can flash with stock recovery are ota.

So if you are not a noob then why are u asking for such things that are common sense. Nobody ask these things now. I just passed class 12 and i know most of the procedure for tweaking an android. I can even write partition table. You just have to search. Not post like this and expect the dev to post them too. Do a little bit more work to achieve something.

Coming from a Huawei g510 where i got my roms on Modaco, and The zenfone 2 here at xda the posts were well put togther with all the info needed , I have found quiet a few here with very little and it's kinda lazy on the posters part.
That is all. I ain't a programmer (although i touched on some c++) but I ain't a noob just like details and not everyone is well informed and there a newbies to flashing roms it's to help them too not brick a device.

From what I see it's mostly non devs just copy paste guys who are doing it.
Does it hurt to have a small guide or at least the fundemntals of requrements for the installation of each rom?
Waiting on my redmi still order prcessing, hurry gearbest hurry I am back on my g510 as my asus went for a swim in my tiolet!

Nice idea, looks like there's no room for a newbie on XDA anumore (in remembrance of XDA 2012).

Is it possible to port a custom rom from RN3 SD to MTK?

Dear xda community,
I just made my account so I can ask the question written above (and join your community :fingers-crossed. I don't ask for instructions, guides etc. I just want to know if it's possible and if so, how hard is it?
There was a guy who always ported the MIUI official global developer SD roms to the MTK phones. It worked pretty well, though I'm not a great fan of MIUI's design & bloatware. Long story short: he did it in a very short period of time.
There are many Android 5 (6 at best) custom roms out there, though we have Android 7 (offical resurrection remix OS) for the SD device. MTK and Snapdragon share the latest MIUI/Android version (7.11.23), so maybe copy/paste files is possible until a certain limit?
Thanks for your answers and best regards (and sorry if I'm not seeing any obvious mistake, I'm just learning C++ at the moment and that's all )

Actually No... SD and MTK are 2 different architectures and the kernel having the apis implementated wont be common... But it would be little simpler if porting rom also shares the same archecture... So u need to browse similar roms which are in same architecture....
Also to port across different OS versions, you need kernel source to provide respective drivers.... Hope it helps

Need help to start Android Engineering

I am completely new to Android Engineering and want to learn it. Till now, I have tried building aosp oreo from repo. It is built successfully but I don't know about the use of all the folders that are downloaded by the repo. What is the use or importance of each folder in repo? Where can I learn more about this?
I have also modified my stock firmware (only removed some bloatware apps) and rebuilt the firmware. I haven't installed it yet. I used android kitchen which helped me with signing the zip but I am afraid the signature might be for testing and not the official vendor signature. I have phone with unlcoked bootloader but it's still on stock recovery. According to my knowledge, unlocking bootloader helps us to flash unofficial files but people at XDA say that we should also have custom recovery to flash custom ROMs. Should I flash the modified ROM built by me in device with stock ROM and unlocked bootloader?
My device doesn't have official TWRP support. How can I port recovery or build it from scratch for my phone?
Also, I have only modified stock ROM and need to learn porting ROMs like porting MIUI for my device. How can we port ROMs?
Sorry for asking all these at once but I tried getting answer one after another which confused me a lot. I am a noob in this field.
I read XDA thread of TWRP developer which included a guide on how to build TWRP for any device. But as the author said, that post wasn't for noobs. Maybe I need to learn a lot before I reach that level of understanding. But I don't know what to learn and from where. Please help..
And one last thing - What is a device tree? Or vendor tree? I saw these words many times when I was trying to understand the above things. But I still don't know what these are and Google doesn't help. Thank you everyone..
Hi
there is this section here https://forum.xda-developers.com/android/software
you`ll find some sticky threads of the top with plenty of info , have a look !
you may also use search and type XDA University , it will reveal also some useful links
Good luck !

Hello. Im new to the fourms. just tying to learn some things about android :)

a few of my questions are that
what are some good custom roms (not as in roms for specific devices like brands)
2. what are some phone brands that have a lot of custom roms?
thx thats all
Hi, guys, This is my first post need some tips on ROM +1
Thread moved to correct area.
1. LineageOS, ResurrectionRemix, BlissROMs, etc. are the biggest ones.
2. Most of the big brands have custom ROMs. Google, Sony, LG, OnePlus, Samsung, Huawei, etc. all have custom ROM support.

Need a custom rom suggestion.

I need suggestions from those who are using custom ROMs, What I need is a smooth ROM with good battery performance which passes Google CTS and other stuff without root, as I want to use UPI apps in India, Secondly I want it to have all the permission features like allow once or allow only while in use.
Next, it would be good if it has face-unlock. I haven't been on XDA in a year so don't know how much more development happened in this time for Poco F1 but last time I checked FaceUnlock didn't worked.
So please suggest some if you're using a custom ROM and that ROM fullfill my needs. Thanks

Reloaded OS and Paranoid Android based on Android 10. Smoothest roms you can find for poco f1. Both of them have good performance and battery backup as they are both based on caf sources. Safetynet passes by default.
Both have IR based face unlock.
ROM suggestion
I will suggest two ROMs. If you want Oxygen Os experience I am suggesting you Eutopia build and if you want AOSP based ROM I am suggesting CORVUS OS. They both have telegram channel available so if you have any query about any of the following ROM you just ask in the group so will get a solution. These both ROM don't require root permission to pass safety net.
