[Q] Questions about hacking

Hi guys
I am writing a paper and I would like to have your point of view
1) Is it dangerous to change the rom (security for the user) ?
2) Is a rom could be infected or made with bad functions ?
3) An operator can detect a non official rom ?
Thank you very much for yours future answers.

Ad.1 Theoretically yes. But as long as you get a custom Rom from a "SAFE" place (like Xda), with a big community, it should be quite safe, as sooner or later any issues would most likely be picked up by someone.
The other problem could be a fact you have to root the device to flash a custom rom.
Ad. 2 Yes it is possible, and it could happen, but I don't think anyone ever come across such an issue.
Ad. 3 Probably not, but I'm not entirely sure about that.

1) It's just what you call security. If you do something wrong during the flashing process, like flashing the wrong ROM for example, it will surely brick your phone. If you're talking about virus issues and stuff like that, I'll procide the same answer as the person above me. Theoretically yes, but the chances are really small.
2) Yep. Particularly if you flash someone else's backup, you could flash a troian. Please mention I said 'could', because again, the chances are really small.
3) Could be, could be not. Not completely sure about that one. I think they can't, but I'm not completely sure.
Point 1 and 2 have about the same answer: Improbable, but it is possible.

Ok bro
First of all thank you very much for your answer. It s usefull
If I understand right, in future, we can imagine that a "bad" hacker team produce a specific ROM with in apparence very interesting functions but in back, a function to create a zombie park. Right ?
The question I think, it s how is possible for an operator to do security on Android ?
I read a lot and I found no sources regarding how an operator can build his security with Android phones. I mean on network. I can imagine than for him, it will be interesting to block some specific appli or roms but i dont know if it s possible.
Thank you very much.

To fight modified roms, perhaps manufacturers can secure their bootloader ?
I ask this because I think only manufacturers can fight modified roms. Right ??

[Q] [q] help needed now!

im New to all this developers , and Rooting & modifying stuff.
But i really want to learn .
Like i want the basics first like how to root , what happens when you root , what to avoid , i mean i wanna know everything. Is There Anybody ? annnnnyyyybody Who will like to be a helping hand , and teach me the basic nessecities of this Developers world. ?

And i have an HTC Evo 3D , ive always been in to technology , especially Phones , im just ready to take it to the next level and start rooting .

Yeah, I had a blackberry bold 9780 since the day it was released, and I always used to follow this site on android development. But when the Nexus S was released on Rogers, I had to switch, and it took me a while to figure out how to Root the device but I love everything about this phone and technology for that matter.

so In a sense , What does rooting do for you.?

It gives you full control of the phone. One some phones, you can't do some things without root. Like screen shot programs need a level of access to your phone that is only available if you root it.

one of the best parts of rooting is having the ability to use customs roms which add a ton of features to your device. You can also over clock for faster speeds, take screen shots,use custom themes to make your phone look cooler, and a lot more.
Cheers
P.S. if this is good information hit the thanks button

If you want to learn some app development you should check out Cornboyz youtube channel.. i was in your position a couple months ago and that helped me a lot. Theres nothing about rooting there but start at tutorial 1 and its an awesome intro to eclipse and android dev

As a member posted above, it gives you full access to your phone. So you can change the rom, kernal, radio band etc. It's a neat thing to mess around with if your into technology and these types of things.
But do be aware that rooting your phone does void your warranty

just search through the whole forum, you'll find many many many information

[ROM] Rom for my A50.

Fast and Stable.Plzz
Sent from my A50 using XDA Free mobile app

Detail in answer is based on impression left by the question ...
The best help requests start by saying what the user has already tried to solve the problem, so after reading your question, 'plzzz' don't mind if I base my reply on assuming you've got no idea how to go about this. And, that's OK!
Do a search for NeedROM and go to that site, first.
ROMs are very specific for the hardware they're being flashed to. Some manufacturers with use the same model number and but make small hardware upgrades without changing the model. NeedROM is very good for this, often showing photos of identification beneath the battery -- all this must be identical to what you see, on your phone.
The same ROM may be available from other sources, but often with enough missing information that you're still not exactly sure if its OK.
If the ROM isn't a perfect match, you can 'brick' your phone. If you're careful, you phone will again be like new. :good:

What is A50? You need to be more specifics

[Root]I want to learn how to Root Smartphone without 3rd Party app?

Hello, everyone and the moderators!
I just joined.
I had happily used Android in Datawind Tablet for 6 months, two years back, when it developed a snag. I received a replacement. It had third-party apk download site of Datawind, not the Google's Playstore. I was displeased by this limiting option. So I returned back the device and got back my full payment.
I informed Google about this but Google said that since Android development is under Apache license, not GNU license, people could do as they pleased.
A few months back I was interested by the Whatsapp app. It can't run on Android-x86 on PCs. So I planned to buy a cheap smartphone to test it. I bought a Karbonn Titanium 3Dplex Lite.
Everything alright upto this! I was happily using Whatsapp, when my notice was brought upon a third party app called Tap-n-Buy. I could not uninstall it.
I have been an exclusive Debian Linux user for the last nine years. So I thought I could su and remove it.
But I found that not only su is not possible ordinarily in Android, but in the android-porting forums it appears to be a taboo word.
Very well! I researched and found the site techaddictted.wordpress.com/2016/06/01/9-apk-to-root-android-phones-without-pccomputer
I downloaded a few rooting apk files from their parent sites.
In the meanwhile I was helped by Androidcentral, link, androidcentral.com/root and digitaltrends.com/mobile/how-to-root-android, in the preliminary research. I was also helped by the android-x86 forum.
I continued to post a few queries in "android-x86 and ancroid-porting" but am not receiving any replies:
Topics:
(1) Customise Pre-installed Android in personal Smartphones?
(2) How to copy the entire Android OS installed on smartphone to PC running Linux?
(3) Why Rooting Android on Smartphones is a taboo subject?
(4) How to install Android ISO on Smartphone from Linux Systems?
The process being: downloading the installed OS from my Smartphone to my lap-/desk- top, su and remove problematic apps, and put it back on the smartphone.
But needless to say, one of my posts has been refused. The rest have yet not been approved for general viewing.
With my threads to android-porting I came to have an intuition about some issues:
(1) It appears that Android rooting is a taboo subject in Android google usergroups.
(2) There is no direct super user level in android to be root'ed but only 3rd party apps.
I downloaded some of the apk files from the links provided by techaddictted.wordpress.com/2016/06/01/9-apk-to-root-android-phones-without-pccomputer . I checked those apk files using online virus malware scanner and found all of them problematic.
I continued to search, and from MakeUseOf - Technology, Simplified, (i.e., makeuseof.com) I was led here.
Now my interest is very detailed:
Ultimately, I wish to download the Entire Installation on the Smartphone of the custom Android by my mobile developer, tweak the files, remove a couple of problematic apps and then reinstall the tweaked files back to the smartphone again.
I know that in Linux I could remove root password using booting from a different liveCD, use some tricks like chroot and then remove and log on as root with a new password.
As a Linux aware person I can understand that may be Android is trying to suppress information about rooting a device to keep the proprietary apps running. They have their limitations.
But on the contrary, Google Android itself warns me of the third party software, which is indicates as malicious. Here is the link: drive.google.com/open?id=10N1HtycG87_5LW59-1GGKI32b1ucN0bC
It was these Tap-n-Buy warnings that actually aroused my interest in rooting my device, to be a superuser and remove this software. Otherwise, this app doesn't appear to be removable.
Could I be helped?
We will take one baby step at a time. First know whether it is at all possible to be a superuser without a third-party Superuser app.
And continue from there to the next baby step.

Root on Android is a security exploit. It is not taboo here.
It might be that your device can't be rooted (not all can be) mainly if it's a no name cheap devices.
Yes you need third party apps as root on Android requires a kernel change.
As for pulling the OS off a device. You are out of luck on that. As the OS is packaged differently when it is zipped and then it is decompressed when flashed.
Your best bet would be to see if your bootloader can be unlocked. If it can then you will need to find the kernel source and build aosp for the device.

Thank you for responding to my queries
Thank you Sir, for responding to my post and replying to my queries. I have to admit that I did not expect a reply so soon.
I thought I did not write clearly enough to make it clearer, and I apologise for the ambiguity. I would try to clarify certain aspects of my post based on your observations.

Oh no. Karbon is not what you think. They like Micromax use rebranded devices from China. Normally cool pads by Chinese name. (I have helped with many India based users with different oems) even helping getting kernel source release for the M1.
Root files will always trip anti virus programs. It's because in a way it is a virus. Root apps use security exploits to get root. Nothing to worry about as long as you are smart about it. Heck you can ask any developer here "what anti virus program they use" and the majority will say none. They are faker then a Chinese knock off. They have even been found to fake false reports on files for their competitors.
If your device has an unlocked bootloader then you can flash magisk which is the best root app.
If you come across an app that doesn't need to be flashed and is just an apk. Run the other way. Those use majority security exploits to get it done but most of them get patched in the monthly updates. So it doesn't always stay. They also tend to add malware to the device.
As for a step by step guide. I can only do what you can. That is to search xda to get the info I need.
I'll do what I can and see what I can find. No promises. Do some research yourself as well. It will help you learn the ins and outs and get you to know the lingo.
Mind you. You will still need an app to control root. Which is encludes with the magisk zip

I will try with your information
Thank you, Sir, for the additional information for my further research and experimentations.
I will try to find flash magisk zip and then use it.
BTW, I would seek this opportunity to request you to advise me about the best Smartphone that has everything accessible, from open bootloader to root permissions for my further experimentations.
Until then, I would seek your permission to be absent from this thread.
Thank you once again, Sir!

Dude. Relax. I am no longer in the army. No need to call me sir. Lol This is a forum. People reply when they can. We are glad to help in our free time.
Do some research on magisk. Don't just go flashing. But first things first. Find out if you have a bootloader that can be unlocked. If not then you won't be able to go further.

Thanks for replying again so soon!

Yes, I have just been researching on this very issue. But it appears to involve installing Android SDK, as per howtogeek dot com/239798/how-to-unlock-your-android-phones-bootloader-the-official-way
Is there another, easier way? A shortcut?
BTW, please refer to my request in the post #5 on a suitable smartphone for experimentation.

All you really nead from the sdk is the adb files, so you can push commands to your device. There are a few basic adb packages. Here is a good tool. This will work for now to do what you want. If you ever decide to build roms for your devices from source then you will have to have the whole SDK.
While there are many sites one the internet XDA is the only one you will ever need for modding your device. Any question you may have as been asked at least a hundred times in these forums. Use the XDA search or the XDA search plug in for your browser to hel find the info you need.
Many devices have unlockable bootloaders. One Plus has the currant Dev support right now as they are good with 3rd party developers for the most part. Depending on the device unlocking the bootloader has back draws (sony with DRM keys and such) lessened security (no matter what any one tells you). Just see which devices XDA portal team is talking about. They are normally good dev devices. Like I think Honor is working with XDA to be as open as possible.

Thanks for replying again so soon!

I indeed did both full and advanced search in this very site for my OP thread title.
Needless to say, I didn't find any. I couldn't. I always ask incisive questions, otherwise, I don't.
Once in flow, I asked you about unlocking the bootloader. As I asked, I began my search as well
So Honor and One Plus? Could you please inform about the specific models? I will then talk to Amazon India for one of the two, and also about a completely open Smartphone, without locked bootloader, locked root, locked third-party app (I will do them myself, if required) with Android pre-installed, for experimentation.
Thanks a lot!
I will take some time to be familiar with xda, but I will eventually, if the quality that you vouch for is really there.
I admire all good things and am ready to pay more than money for them.
Regards

Yeah the site search can be a bit bad. Due to the size of it. You will get used to what key words you will need to use. The site has been here for almost 20 years now leading the way in mobile hacking and development. So there is a lot of info. But a lot of it is pre-android as well so don't be deterred.
I had a look at the devices available from Amazon India. Look in out forums at the device threads and compare them. The 5t is the only one I can say for 100% that it will do what you want.

Ah, great!
Thanks for posting a reply so quickly.

I am so sorry that I was editing the post #9 while you replied.
Okay, One Plus 5T? Shall enquire with Amazon.
[later addition] Yes, checked. But I won't buy it. It has a (redundant for me) very powerful camera and a very powerful HD screen, which I won't require.
The device is expensive chiefly because the powerful camera and the HD screen which I don't need. I simply want to experiment.
So I will go with the best of the original Chinese Brands that flood our markets.buy any one of the smartphones, as advised, 2nd hand. Not the India-nised Chinese Brands re-packaged by Karbonn or Micromax — a priceless information you brought to my notice. I will enquire with our local mobile repairers and software updaters.
I had already written to Amazon in the meanwhile. Though the CS team has replied, they are not very competent. I am presently waiting for the Executive Customer Relations Team to respond.
I will gradually become familiar with this site, for sure, and learn to search optimally.
Thanks once again!

Samsung Galaxy XCover 5 ROMs?

Hi people,
I'm looking forward to buying a Galaxy XCover 5 but I really want to avoid all the Samsung bloatware stuff.
For now, I didn't find any single custom or AOSP ROM for it.
Did I miss something?
Also, I realized that this smartphone isn't in the Samsung topics list yet.
Best, taiBsu

Do a Google search for:
"Custom ROMs for (the specific model number of the device)"
If that doesn't find anything then there is nothing for that device.
Use this same search for for every device that you want to investigate, just use the model number for each device when you search.
Another thing you may want to investigate. Do a Google search for:
"TWRP for (the specific model number of the device)"
If that doesn't find anything then there is no TWRP for that device, which means there are probably no ROMs for that device either because it requires TWRP to flash custom ROMs.
Anytime you are interested in a device and you want to see if anything is available for it, do these exact searches and it will find if anything is available for that device.

Hi Droidriven,
thanks for your reply. However, when I wrote "I didn't find" that meant that this was the result of following exactly the steps you described. It's not that I was just too lazy to ask Google, more of asking specifically in the XDA community for potential less popular or unofficial ROMs that might not be found by simply googling them. Also, it might have been possible that some devs are at the moment working on a G525F version of some custom Android.

I literally registered just to say how much of an absolute waste of time you are. If you're not going to help beyond not reading people's posts where they've said they've looked for something and just by default go to tell them to google it because you don't know it, then stop wasting all of our time and just delete your account. Your ego is atrocious for a forum troll. Go touch some grass.

It wasn't an "I don't know" reply. It was an "if you want to find ROMs for your device, this is how you do it" reply, because that is exactly what they needed to do to see "IF"(keyword, IF) there are any ROMs for their device, because, IF there are ROMs for their device, the search I suggested would find it/them, if it doesn't find anything then there is nothing, which answers their question pretty directly. Yes, they said they already "searched" but how am I to know whether or not they did proper and valid searches? How do I know if they searched specifically by model number or not, since they didn't state what searches they had done or how thoroughly they had done it? What if the searching they had done was vague and non specific? What if, after potentially vaguely and non specifically searching and finding nothing, they came here to ask? If their searches were vague and non specific, then, my reply would have helped them refine their searches specific to their device, if anything exists for the device? There are more layers to the scenario than you realize from the outside looking in.
My reply told them everything they needed to know in order to find/not find what they were looking for. It was also to indirectly say "if you've already done those searches and didn't find anything, then that is a pretty good indicator that there is nothing for your device". Given that they already did those searches and didn't find anything, that means that coming here and asking was the ACTUAL "waste of time". The only time I wasted was to respond to a question that they had already answered for themselves when their searches didn't find anything, whether they knew it or not. Now, you've wasted time debating a reply that was actually a valid answer, you wasted even more time by registering just to do that. Your reply is how you feel about it, but, in reality, what you have had to say about it is completely irrelevant.
I'm assuming that you think a valid answer would have only and expressly been to post a ROM for them, a ROM that doesn't exist? Are you the type that thinks I should just give them a fish that doesn't exist rather than teaching them to fish for themselves to see if the fish they are looking for exists or not? Exactly how was I supposed to reply to a post when the answer they are looking for doesn't exist? You call my post "trolling" even though it told them exactly what they needed to know in order to find a valid answer, if the answer exists. This actually makes you and your reply the "troll", as you call it.
Have a nice day.

Did you find some rom? just going to start searching for one...

Minor news:
Managed to get Lineage OS 20 GSI by AndyYan on the phone by modifying original fimware AP file.
However right off the bat there were two issues -
1/ after phone went to sleep by hitting the power button once to lock it the screen stops reacting.
Luckily the battery is replaceable
2/ it did not even ask to unlock the SIM card
Right now I am trying to de-bloat the original firmware a bit for daily usage. Still don't like it.
That said there are some resources out there
- Samsung provides official kernel for Android 13
- you can find twrp for A21s which also has Exynos 850 - would be nice if someone tested it

Got custom kernel and Lineage GSI into one ROM. (lot's of work on that samsung malicious compliance "open-source" kernel). Flashed to the phone but...
Stuck on the "This phone is running unauthorized software." at the moment.
Not sure where the issue is. Wheter with the kernel I managed to prepare of with some security mechanism.
Probably need to disable proca or something. Maybe time to give up for now.

The "unauthorized software" thing is usually because your running custom/unofficial software on a device that has a locked bootloader, the bootloader wants to see the software that it is "supposed" to have.

Nope, bootloader is properly unlocked. I made double sure about that.
I used to have S10 and that screen was pretty standard.
Reading some posts on that it seems I might have to downgrade firmware to some older version.
Unless I got the kernel wrong.
I remember that back in the day ivan meyer or someone of similar nick used to make LOS for it and always there was specific version of firmware needed. Not the newest one.
I tried with the newest one sofar while the kernel source from samsung is probably kind of late 2022-ish.
Perhaps I will try with older firmware later this week.

Ended up just rooting with magisk and debloating since I needed to start using the phone.
Battery life for my low usage is a week now.
No issues sofar.

(Apologies if this is hijacking the thread - it seems to be the only place mentioning the xcover5 and I did originally come here looking for ROMs)
My new xcover 5 arrived today, but I can't get through the setup - it goes through several screens then prompts for a Microsoft Business Account - which I don't have. The only option from there is Sign-in or Reset Device. Samsung have said to return it to the seller, although am not sure how much their chat-support understood my problem. None of the setup guides / marketing material mention needing a Microsoft Business Account... so I wonder whether I've been sent a phone that's been previously used and somehow locked down to a big company's settings - and if so whether I can reflash/splat it.

It might be safer to just return it because of warranty laws..don't know how that works where you are.
But if you want to at least try then:

If the phone is hard-locked by some corp on firmware level you might not be able to reflash it.
