Question about custom rom safety/security - Samsung Galaxy S7 Edge Questions and Answers

Hey guys, so I’m a fairly new android user. On S7 Edge running stock nougat touchwiz firmware. I am very interested in trying a custom rom like remix resurrection to get a snappier stock android performance and have things like software navigation buttons on screen but a couple of things worry me a little.
Stock firmwares have security updates etc. How safe is it to use a custom rom, like a well known one? What’s stopping the maker of a custom rom from baking in some malware or virus that collects data/passwords and other private information? How often does this happen and does it happen at all? Is it safe to use a custom rom as a daily driver in terms of security?

That is highly unlikely to happen, most of the devs that Build roms are well known and respected, as far as security patches custom roms are almost always up to date, and the kernels are for the most part set to enforcing (more secure than permissive) , so if you don't do anything stupid and shady, you won't encounter a problem.
On a side note, you are asking in the wrong section, next time ask a question in the appropriate place.

This section is for rom development, questions go in the questions and answers section, with that many posts under your belt you should know things around here, but anyway I hope I helped.

[Q] [NOOB] Help building custom ROM for S5 G900H

Hey guys
I'm currently working on my first custom ROM mainly because there are currently no ROM for the dreaded G900H (aka Exynos) version. For this, I already downloaded a stock ROM and created my environment using Android Kitchen. So here are my questions:
1. I was able to follow and execute all the instructions to extract the custom ROM, install root and busybox. But first... is Android Kitchen even compatible with Galaxy S5?
2. Is it important to keep the CSC info on the new ROM? How can I backup current CSC info from my stock (carrier provided) S5?
3. How probable is to brick the phone if I flash a very alpha ROM as the one I'm supposedly cooking? I already have a nandroid and EFS backup
Thanks in advance for your answer and patience.

i need custom rom too for my sm-g900h
could anyone post full guide and video showing us how make our custom rom?

Sent from my SM-G900H using XDA Premium 4 mobile app

Is there still no hope for the s900H ((((

Funny, implying that this is an statistics game. It is not and it's ridiculous to blame developers for the lack of support.
Pretty much everyone that actually develops got the Snapdragon variant, if I had a choice I'd gotten that just by the amount of code and AOSP possibility.
Exynos was only supported by a couple of devs, it's all Samsung's fault - not devs. None of them currently has an S5.
Use xposed, greenify, titanium backup and there are few reasons you'll need a custom rom.
Xposed opened a new world of possibilities to modding.
Edit: Exactly that demanding attitude is what puts devs off. Other regions are usually more polite and grateful and that's something devs have noted in the past....

Sorry if I didnt make myself clear. English is not my first language. When I mentioned the millions of user was only to imply that more users, the more chance to have a genius among them. I didnt mean to have a demanding attitude. I was trying to say "Iknow you are out there, I know you are developing something for all of us. We are here waiting for your effort.
@CiDev:
You want to share your ROM for "H" here?

I wouldn't bet *anything* on it being released, it looks to me like an abandoned project...
The whole 'I can't work on this because I don't have money' turned me off instantly from that ROM.
On topic: I have been working on a custom kernel for our device, mainly trying to improve battery life. I'm still testing, if it's worth it, I can release it.
It's based on the contributions of others, so it wouldn't be fair for me to keep it private, I just don't want to release something that will break stuff.

1 - yes.
2 - make an nandroid before
3 - if you have a brick, restore from your nandroid and ready again

why don't open a section for cyanogen??

hello. as most users have stock based modded roms, why don't separe the cyanogen? these roms confuse users with rare problems too...... i hope this solution because this is sometimes a problem
easiest, just to go cm homepage.
i don't need cm... the cm's rom invade the android development note 3, i ask why isn't there the separation
Most users don't use stock based roms many many use CM and without CM their would be a none to poor development scene .
One of the basics is if you don't understand then don't use modded firmware .
i asked for forum organization, and not for say that cm is better or not than stock based.... your answer is not pertinent to my question. goodbye

What? CM "invades" Android development? :laugh: You can guess who the first team was, to modify Android and present it as a custom ROM in the Android Development section. What's actually invading the Android Development section are all those "Stable, ROCK SOLID,® 100% Stable | BETTARY LAyF ◄◄©" TouchWiz ROM's! Those need a seperate section called "Stock ROM's with community bloatware instead of OEM bloatware claiming to break the barriers of physiks and being faster than light and breaking the first and second law of thermodynamics"... Not all of them of course. Exceptions are there.
Know where you are and why you are here!

Advice on Purchase

Hello,
I'm strongly considering picking up a LePro 3, but I do have some concerns. I understand that the stock software isn't very good and I'm looking towards the community to create excellent ROMs for this device, but I do have some questions:
Do we have a clean method for root/unlock/recovery?
Is there anything stopping developers from putting together ROMs that are optimized for every aspect of the phone? i.e. enough source from LeEco?
How would you say developer support is for this device? I'm a fan of official ROM builds instead of using unofficial. Has anyone announced upcoming support for this device that I can look forward to?
Aside from that, feel free to mention anything else I should be aware of before purchasing the phone!
Thanks so much!
Do we have a clean method for root/unlock/recovery?
I have no idea what you mean by clean but if you can use adb then yes we do. If you are looking for a one stop shop all in one unlocker then the answer is no. look here for current method:
http://forum.xda-developers.com/le-pro3/how-to/flashing-guide-roundup-leeco-le-pro-3-t3511901
Is there anything stopping developers from putting together ROMs that are optimized for every aspect of the phone? i.e. enough source from LeEco?
I believe all source code has been released.

There is minimal development currently. One person is trying to build a Nougat 7.1 Rom. That's a pretty big feat so it will probably be a while. Look here:
http://forum.xda-developers.com/le-pro3/how-to/7-1-progress-t3511474
There is a developer that posted a debloated version of the x720(international version) of this rom already. It will work on our x727(US version). It is an older version though so there's that. Look here:

This is literally the smallest compilation of threads I've ever seen for a phone so starting a new thread to ask these questions is pretty silly. Since it's the holidays, I've been nice and responded to what could have easily been found in a couple of minutes.

Thanks for the reply.
The reason I compiled these questions were because I was hoping for more specific answers and some clarity. Perhaps I wasn't clear enough my initial post and for that I apologize.
I was reading what seemed to be conflicting information about the recovery software and process in which to flash it to the device. It looked as if there wasn't any goto method or specific TWRP version to go with and that this was still somewhat experimental.
It's good to know that the source has been released. I was seeking info about LeEco and people were saying that they didn't release source code for their phones as company policy.
While I've visited the ROM forum section, I was hoping someone would have insight into official ROMs instead of what currently exists there.
For the US model Le Pro 3 (X727) I would recommend using this (http://forum.xda-developers.com/le-pro3/development/x727-model-persistent-bootloader-unlock-t3500388) method to unlock the bootloader. That's what I did and had no issues. From there you can use TWRP to do a full wipe and install the ROM of your choice. Of course, I would recommend taking a backup of everything before doing this.
I'm running that CM 13 build with no issues on my X727. It's also possible to get the IR blaster working if desired.

Best custom ROMs for LG G4?

Hi, guys!
I saw there is already a thread about this, but it is quite outdated so I decided to start a new one. So since there would most probably NOT be an update to Nougat for our phones, I plan installing a custom rom, but since I am a newbie in this field I decided to ask for opinions. Honestly I am mostly attracted by the LineageOS 14.1/15 as successor of the CM, but there may be better options. I found some threads about LineageOS 15 been released but the link for our phones has been removed, reasons unknown. The 14.1 seems quite stable and with good reviews. But nevertheless please share your experience with any custom roms that you have, also please share whether G4 specific features like the double tap to lock/unlock the screen work with it?
If relevant I have a h815 model.
Thank you,
It is personal. You can ask that what do you use custom rom or why do you use LOS etc.
You will get more answers like this way.

On h815, there's an 8.1 rom (aoscp)

Will I get always on display if I install a new ROM?

I'm really new to this, so please bear with me. I rooted my phone a week ago. I was wondering if there was any way of getting an AOD through a new ROM. I haven't installed a new ROM before, so I'm not 100% sure about how it works. Say for example I install the firmware found on the Galaxy S8 (is that even possible?), will I get access to the AOD setting?

This is a difficult question to answer...
The only Firmware ROM's you will be able to install on a Rooted Only Device is either the Stock Firmware or a TW Based Firmware.
Your answer regarding the previous statement SHOULD be a Yes...
If your referring to any of the Custom Firmware ROM's (like LineageOS, crDroid, Resurrection Remix, etc...), you can only install them via a Custom Recovery (like TWRP for example) and that requires the ability to Unlock the Bootloader.
Your answer regarding the previous statement can only be obtained by asking about it within those prospective threads.
Some/All of the Custom Firmware ROM's can/may have one or more bugs that the developers are working on in one way or another that may or may not have a current workaround. This may or may not include the AOD.
This is why its not a very easy question to answer, specifically, in a "Generalized/Encompassing" way.
I hope that I had explained this okay via text... :thumbup:
Good Luck!

UNLESS asked to do so, PLEASE don't PM me regarding support. Sent using The ClaRetoX Forum App on my Enigma Machine {aenigma = Latin for "Riddle"}.
Even if you put a custom ROM *made for the S5* from this subforum, the AOD function drains a large amount of battery. Not worth it at all, phone becomes unusable.
There are lots of apps that brings AOD to ur phone. Search through play store.
