[Android Q&A, Help & Troubleshooting] Zalbor:
Well, hello. I'm most certainly a noob, although I do have experience with developing for android and using Linux on a PC system. I haven't done any rooting/unrooting/custom-firmware-flashing before, however.

I believe this question to be about Android devices in general and so I'm posting it here instead of a device-specific forum.

The short version of my question is:

Is it possible to install a custom firmware on my phone, but prevent apps installed in it from having root access?

The long version:

Having read about how the Android OS works, I understand that each app installed in a system basically has its own user account, and that's how privileges work: The OS simply doesn't allow this specific user/app to access other apps or hardware.

Unless I'm mistaken, rooting a phone makes all apps run under the same user account: root. Which means that all apps have access to every other app and all hardware on the device.

I found many web pages that explained that this is a security risk as malicious code could then use anything at all on the phone. This makes sense of course, that's why most applications on a Linux system don't run as root.

I understand why rooting the device is necessary to install a custom firmware on it, but what I haven't understood is why the device has to stay rooted afterwards. Isn't installing a custom firmware basically replacing the OS on the device? If so, couldn't I replace it with an OS that doesn't run everything as root but instead runs every app as its own user, like unrooted devices do?

I've searched this website and others for information on this but I haven't been able to find something that answers this question.

I found explanations for why unrooting is needed to install a custom firmware, but they didn't include why the resulting system can't be rooted.

I found guides on how to restore the original firmware on a device, which isn't what I'm looking for, although this process is called "unrooting" (the word seems to be misused here, but maybe that's just me).

I also found guides on how to trick certain applications, which won't run on a rooted device, into thinking that the device isn't rooted. However, the reason I'd prefer my device not to be rooted isn't to trick any applications but for security reasons.

What I'd basically like to do, is install custom firmware but, once that's done, ensure that applications I download from the Market or install directly don't have any more privileges than they've been developed to ask for. Is that not possible? I don't understand why not...
[Android Q&A, Help & Troubleshooting] demkantor:
Gaining root access to your phone will not give a single app root privileges, for the most part you will use an app called superuser or supersu to allow or deny any app root access. (Sometimes baked into ROM)

But you have no worries, any app that you download from the market will not have root unless you give it
[Android Q&A, Help & Troubleshooting] Zalbor:
Is that so? Thanks. It seems I was wrong at the very beginning of my logical process.

So, if I understand correctly, the lack of security isn't that anything installed has root access, but that it can have root access. Is that right?
[Android Q&A, Help & Troubleshooting] demkantor:
Correct, even whatever custom ROM you are running has a built in app for lets say messaging, this will not have root access.

You just bow have the ability to do anything (mostly) to your device, but you don't have to

Hi guys!

I tried 3 apps that can use your phone's gallery, browser, lockscreen and call accept like in s4 but none of these work.

Is there a problem my proximity sensor?

Or its another weak point at 4x?

What you get with these apps (air call accept and air swiper)? Are they work for you?
[LG Optimus 4X HD] Gmobilize:
I Wonder the same thing today trying airu swipe
[LG Optimus 4X HD] SpyKnife:
I tried both apps and both of them are not working for me unfortunately. Proximity sensor is working because when i answer a call and put the phone next to my ear the screen go black. So that means that proximity is only activated when you are talking wizh someone.
[LG Optimus 4X HD] PenguinStyle:
And are there any way to turn on proximity sensor?
[LG Optimus 4X HD] Gmobilize:
There isn't a problem with turning on, it's the lack of the sensor, it only supports two distance modes - sensor is covered ,sensor is free so you have to put your hand nearly touching the screen, so wave Is a big problem, it's not being detected most of the times, only by really slowly moving the finger across, I tried other apps with the prox control, and that's the result.
[HTC EVO 3D] micheldaoud:
hello everyone !

i have HTC Evo 3D GSM

SHOOTER_U XA SHIP S-OFF RL

HBOOT-1.49.0012

RADIO-10.13.9020.29_M

eMMC-boot

Aug 4 2011,14:10:29 ( idk if this is important but i will include it anyways)

so yea i flashed 4text recovery and im flashing custom ROM yoda ICS

but everytime i flash the Rom i get stuck at bootloop the phone keep restarting :c

how i can fix this problem ?

i installed the same ROM on my other htc evo 3d s-on hboot 1.5* and nothing wrong happened

so anyone help me ? i kept deleting cache and data factory reset but same thing

i tried 4text smart flashing enabled but same thing

i tried clock..something recovery and still the same bootloop

so if anyone can help me fix it please reply here

thanks in advance
[HTC EVO 3D] zzrzr:
Try flash boot.img in bootloader.
[HTC EVO 3D] micheldaoud:
i tried it but kept bootlooping
[HTC EVO 3D] donkeykong1:
Did you try formating all partitions except sd card? Also wipe everything twice, just to be on the safe side

Sent from Mwakious r EVO lution
[HTC EVO 3D] micheldaoud:
same :/ on bootloop
[HTC EVO 3D] unstoppable_punk_brainiac:
i have kind of the same problem as you have,the only difference is that my phone just gets stucked at the HTC Logo....
[HTC EVO 3D] micheldaoud:
:( please anyone help us
[HTC EVO 3D] hossman:
I don't have gsm.

Maybe you need hboot 1.5* that was on your other phone.

Smartflash is for s on

I would recommend using 4ext though

I would suggest changing your hboot

Reboot to recovery

Wipe all partitions except sd

Reboot recovery

Wipe all partitions again

Flash Rom

Reboot

If it still boot loops,

Then fastboot flash boot boot.IMG

Good luck
[HTC EVO 3D] micheldaoud:
i will try it and then give u feedback thanks
[HTC EVO 3D] micheldaoud:
hossam how i can upgrade to hboot 1.5 ? i totally forgot and i cant find it anywhere :(
[HTC EVO 3D] hossman:
http://unlimited.io/jbhboots.htm

Try at your own risk
[HTC EVO 3D] unstoppable_punk_brainiac:
I managed to make my phone ok again,using a ruu. I think this is the best chance, relock if you are s-on unlocked,flash the ruu via fastboot,and the just use the htc unlock method to gain unlock bootloader and root... It was a log operation...it takes a lot of time ..but well, it worth it. My phone is now ok. You could give this a try. Search the forum on how to revert back to stock rom using a ruu.
[HTC EVO 3D] hossman:
There is no need to relock, and get s on.

You can run ruu through bootloader as a pg86img.zip, and retain s off.

That will give you all stock, but s off

However you need to get the Rom.zip from ruu and rename it first
[HTC EVO 3D] micheldaoud:
so i updated the hboot to 1.5 and tried to flash the custom rom :c didnt work :/ still on bootloop and i tried to flash the boot.img and still nothing :/
[HTC EVO 3D] hossman:
Have you tried other roms?

Or restoring a backup?

Maybe you should go ahead and run the ruu.

I do not have gsm, but I'm sure its the same process of flashing.
[HTC EVO 3D] micheldaoud:
i dont want RUU i want a custom one
[HTC EVO 3D] The Fer-Shiz-Nizzle:
Alright then, RUU, re-unlock (& s-off), and flash a custom ROM.

if you can't fix your problem, the RUU will, and allow you to start fresh. S-off is the best way to go.
[HTC EVO 3D] micheldaoud:
did not work omg :/

after RUU and reunlock and flashing custom Rom didnt work :(
[HTC EVO 3D] The Fer-Shiz-Nizzle:
What rom are you trying to flash, and on what H boot?
[HTC EVO 3D] micheldaoud:
YODA ICS and Hboot 1.53
[HTC EVO 3D] XDA-Dev.:
I remember of facing the same problem when i tried to flash yoda's on HBoot 1.53 ... few days later i downgraded to HBOOT-1.49.007 and tried to flash yoda's , it worked . Worth to try.

Is very good day

I speak about QTEK 2020i Alpine and no other

I succeful unlok my STORAGE was as looked after trying to unlok Extended_ROM.

Try this step

1) Go to registry HKEY_LOCAL_MACHINE/System/StorageManager/Profiles/TRUEFFS_DOC

2) Change value in folder "Storage" by other thing example "Toto"

3) Soft Reset your 2020i

4) With Explorer now you must have a folder nammed "Toto" in my example

5) Try to copy or delete inside a file. For me it's working

6) Return in registry, return original value "Storage" in Folder value

7) Soft reset again

In final you must have your original Storage that is now unloked

Let me know if it's correct for you

I'm be happy and to find solution

[/b]
[MDA II, XDA II, 2060 ROM Development] EMU:
I tried exactly what you said, even that I have tried it before, but it DID NOT work.

that parameter which you changed is just responsible for the name of the folder only, so if you realy could unlock the Storage folder, then it happened with you by chance with another way. if it was just that simple then flashing PPC would solve it also, but it wont, I also tried that.

so please try again to lock and unlock it if u remember the way and tell us in more details. in yours explanations: the name of storage is changed but still I cannot delete or save into it.

on the other hand, if you change the value of MOUNT there to 0 then you will hide your Storage folder, and this is what the LoadvDisk does, it just plays with such a registry parameter, but for unlocking the DLL file is responsible for that, for those who doesn't know what is the DLL, simply I can tell that it is a collection (Library) of functions, now that DLL file has a function that is responsible of unlocking the disk by modifying the non erasable memory ROM. and that is why when you flash the PPC, still your extended rom and Storage is locked, because that data is saved on the ROM that needs a special function and password passed to that function for modifying that data there.

sorry for the long post
[MDA II, XDA II, 2060 ROM Development] apoujade:
Right

In fact i was no certain about "other way" at the moment where i wrote.

Follow exchange about " eNiPlA", i tried modify the tools for SX66 and use it during the test but don't view effect immediatly. It was the same tools that was loocked my storage that today after modification unlock it.

Try this, but i m not certain that to change name of folder in registry is necessary

1) Go to registry HKEY_LOCAL_MACHINE/System/StorageManager/Profiles/TRUEFFS_DOC

2) Change value in folder "Storage" by other thing example "Toto"

3) Soft Reset your 2020i

4) With Explorer now you must have a folder nammed "Toto" in my example

5) USE TOOL ATTACHED HERE and Try to copy or delete inside a file. For me it's working

6) Return in registry, return original value "Storage" in Folder value

7) Soft reset again
[MDA II, XDA II, 2060 ROM Development] apoujade:
IMPORTANT

Don't use this tools (in this state) to lock, but just for UNLOCK Storage . As EMU said, if you try to lock , in fact it lock your STORAGE.
[MDA II, XDA II, 2060 ROM Development] EMU:
yes, that tool worked alone, just install the tool, run it on your device and try only to unlock (ONLY UNLOCK, DONT TRY ANYTHING ELSE) and it would be ok after a soft reset!

thanks apoujade, can I ask you how did you modify the tool, which tools you used for that, if you had the whole source code can you please send it also, because if you could modify this tool, then we may reach to the Extended Rom easier from it also.

I feel we are very near to the solution....

Hi

This tools came from http://www.myehud.com/xv6600/cabs/ExtTools.exe.

I changed with binary editor string "rEiRaH" with " eNiPlA" wthitout missing 2 space before. It's seems to be made for Audiovox with Extended ROM in target. On Alpine it's work for Storage area.

Hello guys, please help me!

How can I unlock the Extended ROM on my XDA IIi? I've been used the search-function but I haven't found any thing that would heplfull fo rme! :cry:

My Alpine's storage was also locked and have been looking for any solution.

Today Asukal informed this thread and I tried ExtTools_modifiedAlpine.exe.

It works quite well and I could unlock my Alpine's Storage area!!

Thanks guys!! :D
[MDA II, XDA II, 2060 ROM Development] animelover:
Stop!

Storage is the place where I can install programs and them aren't deleting during a hard reset and a ExtROM is the place for the software that are using by the providers! Are I'm right? :?:

Than it wouldn't be helpfull for me! :(
[MDA II, XDA II, 2060 ROM Development] reveil:
Yes, you are right.

What I thank all friends here is that I could release the lock of Storage which was locked during the operation of finding the way to unlock ExtROM. :D
[MDA II, XDA II, 2060 ROM Development] animelover:
So if I try this manual, after that my ExtROM is writeable? That would it be cool! :D

Hehehehe, space, I want more space for my porgrams! ^^
[MDA II, XDA II, 2060 ROM Development] EMU:
to clear something out:

everyone is wondering how to unlock the Extended Rom, so as everyone, while we were trying to figure it out, our Storage Folder became also locked (not-writable) so we had another problem, it became our main problem, since the Storage folder should be writable in the normal form, so the ideas in this post are only to unlock the Storage folder and has no relation to the extended rom, so if your Storage folder is already writable, then ignore what is in this form. if you are looking for a solution for your Extended Rom, the answer is: WAIT, we are working on that, and when it is solved most probably you will find the answer in a seperate post..

Good luck to all in the unlocking process..
[MDA II, XDA II, 2060 ROM Development] tony-xd_wang:
so Brother EMU, do you already find the way to unlock the Ext Rom of XDA? I upgrade to WM2005, then the tools I used before is mulfucntion.

I am eager to wait for your solutions, tks!
[MDA II, XDA II, 2060 ROM Development] apoujade:
Hi

Without EMEI, i sue two site for french ROM, but other depends what you want (O2, WWE ..)

Mobinaute it's free but you must ask for download DANGAARD ROM

http://www.mobinaute.com/mobinaute/ (search for DANGA)

Brighpoint it's also free, but you must create an account to access download area

http://www.qtekfr.com/modules/news/

Other way, but not the last version is ftp from xda where you search in ALpine folder

good day guys. ive been having trouble with my sd card lately.. it seems i could no longer add any applications nor files in it yet there is still more than 700mb of free space.checked the slide toggle at the side and its not locked.everytime i add a program via activesync it says "check that the device is properly connected,that it has enough space and is not copyright protected" but nothing has been changed as far as i know. tried upgrading to the latest activesync to no avail.i noticed that this only happens when i insert my card in my device because i tried to put it in a cardreader and added some files up to its capacity and it worked. only problem is that it seems to be locked when i insert it to my device. i noticed this after i installed memmaid and sk tools. tried uninstalling them but the problem still persists.i even did a hard reset and installed all the applications but there it goes again,jammed at the 700mb mark.

could this be a registry problem caused by the tweaks of the applications mentioned?

my specs are as follows:

orange spv M1500 ppc2003 se + 2 gb sd card

i hope you can help me on this guys and thank you in advance.

Hi Oma, I hope you read this. I'm new so I can't post in the official thread of this rom.

I tested the android 4.2.2 beta build 1.5 for rk29 devices in my tablet (AOC mw0711) and worked great but I had some issues:

1-At the beginnig, a window will pop every second saying something like: "system ui has stopped" and I was able to stop it when I activated the full!screen app. The problem was completely fixed when I set the dpi to 120 in the build.prop.

2-For some reason, I wasn't able to place widgets in the lockscreen.

3-The rotation was working but wrongly. With this build I wasn't able to fix it in the build.prop :(

4-Everything looks weird with Dolphin Browser mini. I think this was already reported....

5-With the official rom of my tablet, I can take screenshots pressing both buttons of volume at the same time but I wasn't able to do that with this rom. I think this problem doesn't matter.

6- In settings, I wasn't able to access developer options

7-I know the angry birds thing is an old issue but for some reason, this game works completely perfect with the official JB rom

of my tablet, however I had the problem with the official ICS rom.

Keep your awesome work, I hope you start soon working with CM for rk29 devices:) and sorry for my english

After installing Netflix did you try running the Chromecast app again?
[Epic 4G Q&A, Help & Troubleshooting] CitizenSam:
Yup, I did a whole lot of deleting/re-installing. It looks like someone on the forum tackled this. I am going to try this solution when I get home. Seems like the Netflix App checks to see which device you are running and gives you the corresponding version of Netflix. So the trick is to change the build prop and make it think you're running a more current device. I'll report back when I try it...

Hi. So I just got my Nexus 7 2013 version yesterday and I like it so far.
