Why the root message isn't showed like Hero&Others ?

All others rooted phones have a message showed when an application asks root, why don't we have this on Tattoo ?

On Tattoo root permissions are always enabled

Ok, it's nice but we can't see which application ask root :/
Like Terminal Emulator, when you launch it, the shell is always in normal user "$", not in root :/

This is true, but I dont know how, after isntalling 5faif ROM, terminal emulator shows me the #, id command shows me that I'm root.

I'm on stock ROM, this is the problem i think!
Anybody has SetCPU ?

The problem with this is that every application can obtain root without our knowledge.
It is a serious security flaw.

Not really. Android is pretty secure. Even if you get a brick from a Andirus (Virus + Android), it's a piece of cake to undo the damage.

Because that rom you've flashed contains custom boot.img by mainfram3 that gives to you root at startup and loads tattoo-hack.ko (partition r/w always mounted)

Actually i wasn't having viruses in mind. More like keyloggers and such. SU prompt wasn't invented for no reason...

I think the OP was asking about SuperUser.apk.
It's a modified su plus a service that asks for user intervention when a program calls /system/bin/su. It's nifty and it should be used by everyone.
Android apps are prevented from looking into other apps data. If su is readily available, a app can escalated it's privileges and steal your personal info, by reading data from other apps.

Exactly my point.

MoDaCo Custom ROM 1 includes Superuser apk for root access.
P

Anyone know how to fix Superuser Permissions manually?
I have Tattoo with rooted boot.img (mainfram3)
I pushed su into /system/bin/
Made chmod 4577 /system/bin/su
Pushed superuser.apk from Modaco Rom to /system/app/
Restart sure...
SuperUser Permissions can be executed (list is clear)
But any app doesn't send request to Superuser Permissions.
What i could forget?

Finally, I solved it partially.
Sure, i have rooted boot.img
I extracted from Modaco Custom ROM for Tattoo:
su
Superuser.apk
copied su to: /system/bin/su
copied Superuser.apk to: /system/app
run in terminal: chmod 4577 /system/bin/su
restarted and everything works fine now... Superuser Permissions shows all root-requests, Titanium Backup works, other root-things works too
But i notice, that su-binary from Modaco ROM is about 34-36 kb, but
su-binary from guide of getting root is about 80-85 kb.
1-2 months ago we faced with difference in size of su. We choosed bigger su in case, what it can run "flash_image", smaller su can't run.
But maybe it fixed already? I did not test it yet.

Thanks @5[Strogino]
I was trying to use Titanium today to back up my apps but it didn't work.

What exactly wrote TB?
Did you download busybox via TB?

I don't remember exactly.
It did ask me to download busybox and I did that, but still it didn't work.

[MOD] Adfree System without RW Access to /system

Hey there,
this is my first thread ever created by me in a development forum.
I wanted to share my sollution for a adfree Android system, without unlocking the boatloader to get R/W access to /system.
I did try it on my device, everything went fine, but i will not take any kind of reponsibility for your devices. Also your warranty may be void!
What you need:
- rooted XTZ (i tried it on the 16GB Wifi only version)
- busybox installed
- Android SDK or adb.exe
- patched hosts file, I took mine from my HTC ONE with adaway installed (unzip first)
Click to expand...
Click to collapse
How to do it:
- get a patched hosts file from another device, or use mine (attached)
- put the file on the root of your sd card (so it will be /sdcard/hosts)
- connect your tablet to your PC, make sure usb debuggig is turned on
- launch cmd window, where your adb.exe is located
- entering following commands:
Code:
0. adb shell
1. su
2. stop ric
3. busybox pkill -f /sbin/ric
4. mount -ro remount,rw /system
5. busybox cp -af /sdcard/hosts /system/etc/hosts
- if everything went ok, you should now be able to see all the entries in your /system/etc/hosts file
- sadly you have to update the file if there some new adhosts, but it will remove a lot of annoying ads from all apps and the browser
- the changes are permanent, even at a reboot

Just let me know, if you have some kind of questions!
thanks @juanyunis for the [TEMPORAL-FIX] Remount RW /system reboot thread, from which i got some ideas.
Greetings from Germany

I have been using the AdAway app continuously since Google decided to eliminate all ad blocking apps from its Play Store and from my experience, AdAway does not require an unlocked boot loader to work, it only requires root access, and AdAway has no problem installing a hosts file in the /system/etc directory, so I am curious about why you have to go through all that.

The problem is, that if you using vroot like i did, and you doing nothing else, you don't have read write access to /system. So adaway, adfree and whatever can't edit the hosts file. Therefore is my little mod to get it done manually

after vroot, install SuperSU and then all app ad-blocking apps are working good.

nope sorry, i did it, installed vroot, switched to normal superSU and installed busybox. But there is no RW access, so the ad blocking apps will work, but only to the next systemreboot / userswitch
tried all of them, and tried to manually edit the host file, but without access it will not happen
greetings

strange thing that with root there is no RW access.

I have tested and have for several months ran AdAway on my XTZ, on which Vroot was used to gain root access and SuperSU is installed, and AdAway has no problem writing a hosts file to the /system/etc directory even though the permissions for the /system and /system/etc directories are set to read-only. So, because I have no problem with AdAway and you apparently have a problem with AdAway, I believe it is likely there is a flaw in your root access setup. But hey, I could be wrong.

make system dir writeable

Hi, long story short, I want to make some apps system apps with Link2SD.
I tried using LO14 or some other LO14 based rom and just can't. I read som ewhere that it may be because I have no permissions to write on the system folder. I tried starting TWRP wizard again and setting it to be able to write with no success.
Any help?
I am rooted with magisk working just fine.
thanks!

As I've seen, Some apps don't work well with other SU except for SuperSU. Get rooted using superSU, everything should work just fine. You can always Uninstall and go back to magisk once you're done.

But should I delete magisk, unroot and root again with super su?
Or is it as simple as installing supersu or something?

It's better to follow the procedure you mentioned Uninstall magisk, install supersu then install magisk again... But only flashing superSU zip will also work I guess. You can give it a try. I've done it once I guess

I managed to install supersu but anyways wasn't able to get the /system partition writable. Used many guides and even apps that should do it with superuser permissions and nothing. Just cant.

What kind of error do you get?? Can you do other operations through link2sd??

the error is the following..
mount: '/dev/block/bootdevice/by-name/system'->':/system': Device or resource busy
Thats the error. Tried with titanium backup pro version and it gets stuck "PROCESING" the thing... It uninstall the app I want to move to system app, but then never finishes processing..
I also used a app called mount "/system ro/rw". I grant it superuser permissions and when I hit the "mount /system rw" a message appears that says; "Your device might not be rooted or is it not compatible!"

Do this from terminal emulator (don't use GUI apps for things like this, they hide important errors most of the time):
Code:
$ su
# lsof /system
And watch for processes that hold the mountpoint.
Code:
# kill <that process id, one by one>
if you're sure they're not doing anything important, then try:
Code:
mount -o rw,remount /system
again.
P.S.: you might need to install BusyBox, I don't know if lsof is available out of the box.

I've installed busybox and when I try lsof /system it says "toybox: Unknown command lsof", is there any solution?

app doesn't request root / Magisk doesn't recognice root request

In this case it is terminal emulator or ghost commander (FDROID) that doesn't get root permissions.
I can type in su in terminal but nothing happened at all. I expected that Magisk pops up and asking for SU permission.
/sbin/su is linked to /root/x....
Same for ghost commander, while apps as AFwall+, TitaniumBackup and Xposed Installer are recognised in Magisk. What is the difference?
Ahead I found that Q/A post about
https://www.didgeridoohan.com/magisk/MagiskRootIssues
but either I don't understand really or it doesn't work
I can't create that link in terminal (ln -s /sbin/su /system/xbin/su) as permissions denied (see above)
Additional the link to MagiskSU+ (https://www.didgeridoohan.com/magisk/MagiskSU) is not showing anything.

you first have to mount your /system partition RW :
Code:
adb shell
su
mount -o remount,rw /system
mv /system/xbin/su /system/xbin/su.old
ln -s /sbin/su /system/xbin/su
mount -o remount,ro /system
i just did so, it's hacky, but it worked and titanium backup finaly asked for root

I tested Ghost Commander and it'll only request superuser access if you enable a root option in the app settings (can't quite remember what it was called and I don't have the app installed anymore).
Generally these kind of issues are with the app, not Magisk... Especially if you have other apps requesting root without issue.

you're right, i'm quite new to systemless and have old habits...

Strange thing, after a reboot (hasn't been the first after installing Magisk) it works - and it ask me for root. Don't know what have been the reason. The root option was enabled even before....

anyone find solution for this
/////app doesn't request root / Magisk doesn't recognice root request

How on earth do I remount system as rw on S10 rooted stock rom?

Hi, Forgive me as I've been off the android scene for a while, at least to the point I have had to keep up with developments.
I want to replace /etc/hosts on my device to save using a vpn, etc. to block ads. On my Nexus 6P this was easy, remount rw, replace, or adfreezip.
On my S10 this is not so easy. I am unable to remount system as rw, I presume as this is 'systemless', I am also unable to remount the entire filesystem '/' as rw.
Does anyone know how I achieve this or how I replace a hosts file?
I am rooted with magisk but not with TWRP (I did flash TWRP before but could not install zips to the filesystem from twrp so just did not bother this time).

Thanks. I actually realised though that Magisk has an option to generate a systemless hosts file so I've turned that on and it has done what I need.
I run a pihole at home that has a script which generates a standard hosts file from the blocklist. I can just on occasion save it to /sdcard/ and then cat /sdcard/hosts > /etc/hosts
When I get around to it I will probably just add this as a cron job
