[Q] How can I modify or edit system file in the Andriod System - General Questions and Answers

Hi,
I posted a question in forum about how to connect my A500 tablet to an Ad-hoc networking but after I did some search in the forum I found some steps to solve the issue and it is starting from rooting the device and finalizing by modifying a file in the following path:
sdcard/system/bin/wpa_supplicant
The problem is I can't rename the file (wpa_supplicant) also I can't copy the modified (wpa_supplicant) to the system/bin folder and a message appearing told that this file is "read only" and can not be modified or edited. Note that I used Root Explorer and Root Browser to explore the systems folders.
Please any one can help??

You can't do this because your device is not rooted !
Use Root explorer don't give all super user privilege to your device

my device did not open what shall i do??

As the guy answered, you have to be rooted in order to do that.
Im not sure if you can root tablets, I have never had any interest in this direction because I dont have money to buy one.
But if you can you click on Root explorer, then click mount r/w , go to system/apps.
If it is mounting r/o you can delete system apps, I did that to my SGSII and my battery life lasts much longer.
You also have access to the files that created the applications, the ones you create in Eclipse.If you are a developer , you would know what I'm talkin about.
I dont know any other ways of doing this if you are not rooted and I'm almost sure its not possible, but good luck still.

Im not sure if you can root tablets,

You can root tablets, even the a500 as tough as it is to do so. I am running FlexReaper ROM on my Iconia a500 right now. It's flippin' awesome !
As far as editing the system files, the O.P. may need to actually mount the drive as r/w.
In ES File Explorer there is an option to actually mount the file system as 'writable'......(which will be rejected if the device is not rooted).
Do you see any similar option in the file explorer apps you are using ? If so, try to enable it. Just browsing 'up to root' is not enough......at least for ES.
I would use a root check type of app to verify you are up to a 'true root'.
As for custom ROM's the Iconia a500 tab requires flashing with a custom unlocked bootloader and custom recovery image like cwm, then installing/flashing the new custom or stock OTA ROM and any desired app/system packs if needed. The Iconia a500 is pretty tricky, but possible.
If you do go the way of custom ROM's, I HIGHLY recommend the FlexReaper RF-1_rv3 Custom ICS 4.0.3 ROM for users running the Acer Iconia a500 tablet.
Super smooth, and the only custom ROM that doesn't start with a funny snow screen when initially booting up. A couple other ROM's I tried would 'snow' like a bad hardware compatibility issue or something. Flexreaper seems like it is the perfect ROM for the a500, at least for me.

many thanks for all help;
I used an app to check if my A500 is root and it is called "Root Checker" and told me that my device is rooted and I have root access but when I used Root Explorer or Root Browser apps I found there is a button to switch from (r/o) to (r/w) but when i bushed it never changed to (r/w) by the way I used a software to root the A500 from my laptop this software called ( ICS ROOT 2) if this software is not rooting so can anyone tell me about the right way to root my A500 device which it is working on ICS system bcoz really I confused!!

I actually used the same method so I am unsure as to what is going on here.
Will read back thru my research and see if I can figure something out. I am still new to this rooting/flashing thing, so I don't want to mislead you. I'd rather find my methods in tangible text online, rather than relying on my fuzzy memory.

I am not sure if this will help, but if you boot into recovery, check if there is an option to fix permissions. Run it then reboot normally.
Should be under the Advanced header.

IMOP,your Root explorer manybe havent get the right from super user.
Or,there is a problem with the root app.
My A500 rooted with the method instead of official Recovery.

@ Valkillmore : thank you for your support I'll try this method and comeback again and post the results

Root + SSH + remount
Here's how I do it.
1) Root your device.. lots of tips on this in the forums and the process depends on your specific phone model.
2) Install SU super user access.
3) SSHDroid - Install from market and allow root access (via SU)
4) Turn on SSHDroid and login to it via an SSH client from your computer (see putty for windows, Linux, Unix , and MAC should have it already).
> ssh [email protected] (for example)
5) remount the system drive (it is typically mounted as read-only
> mount -o remount,rw /system
Then you can go ahead and modify files under /system folder. Note: when you reboot, /system will be mounted normally (read-only).

i had the same issue
i had astro file manager, it doesnt have complete root access.
downlaod efs explorer
go to settings
allow "up to root" click allow when super user dialog box pops up
select "mount" right under "up to root"
then go to efs explorer main manu press the "up" tap
navigate to wherever you want. bne carefull with what you change.
i was changing the APN settings on my evo

Samsung Galaxy Indulge 4G nand lock

I just got one of the new Galaxy Indulge 4G phones and tried rooting it.
BusyBox installer is telling me that the phone is rooted however it is nand locked.
and ideas on how to unlock nand on this phone?
How did you root it?

SuperOneClickRoot.
Yeah i tried adb, super one click, and zroot. None of them worked, and for some reason everytime i try to start up root explorer, it crashes trying to get super user. I've tried all means of forcing super user to get onto the phone. No matter what it wont work. Mike thinks its Nand locked. Another thing i noticed is when I used super one click, i had two options at the top right hand corner that looked like names of my device. I can get my serial number with adb, and it shows it. Another darn problem is no drivers are out for this phone yet. Also have no idea of the LTE chip is interfering with this either. So come one come all dev and droid guru's help us out!
So basically I think this means we a need a custom recovery, flash image and stuff. Bah, that'll probably take like a month
K, also tried visionary rooting, which did some wierd ****. I rebooted and it seemed like i had root, but super user still didn't work. It fooled a couple programs into thinking i had root, but it would not let me "touch" the files on the phone. Even though it claimed I had r/w permission.

The Samsung Epic 4G drivers worked for me, also tried the rooting process used on the Epic whoever busybox says im rooted but that nand is locked, i downloaded Terminal emulator and it says im not rooted, also installing superuser not possible, I was able to install root explorer but not any good if doesnt let me delete the bloatware only read.
Yeah, busybox says the phone is rooted but nand locked.
superuser app was added to system/apps. however im not able to mount system/apps with R/W from root explorer. The rooting process seems to gain access to r/w the files but the apps cant.
seems 4G still have far distance from us...
Supposedly there's a work around for Nand locked, but the first one didn't work for me.
With the absolutely beautiful ADB exploit I use, titled rageagainstthecage (ratc), absolute ALL devices can be rooted. This is because it exploit is ADB which all devices use. There is an issue though. Some devices have a NAND lock which does not allow you to write to the /system mount. Because of this, you can’t copy su, sqlite or busybox to /system/bin. This creates some issues but there is a work around. For things that don’t need access to /system (like enabling non-market apps) I can use the ratc exploit to make those changes. If your device cannot use su in /system/bin then you can simple select a checkbox (as of v1.5) that says to use ratc.

This didn't work still for me. So the only other option was unrevoked, but when I went to the site, it listed only HTC. Kinda confused how using HTC roms is a work around for a samsung phone lol. Still need some master guru's help on this stuff.
I too have been trying and am unable to get nand unlocked, I would really love some other ideas. Anyone out there able to help?
I'm waiting 'till the $50 MIR on the 1st, then I'll jump in with both feet.
Some guy suggested to shell root > perm root > restart device. That doesn't work either. I also noticed something called "media scanner" that scans as the phone boots up, i wonder if that's preventing any modified files.
If anyone knows how NAND unlocking has worked for other phones (and im not just talking about what apps to run or what room to use) please contact me so that we can try a few things out and hopefully get a full root for everyone.
Supposedly Mr. Parker rooted:
http://forum.xda-developers.com/showthread.php?t=803682&page=260
I'm asking him through both post and through private message if he could elaborate. Apparently he had trouble with getting Win 7 x64 to work, but it worked with Win Xp. I'm still not sure what drivers he used, and he said he had it not in debug mode. I tried in non debug, and my phone wouldn't even register. So hopefully he'll expand on how he did it. If not, back to the drawing boards, at least till we get a real pro in here.
Got my hopes up that even though we dont have full root yet, I would be able to get rid of the bloatware.
The SuperOneClick is able to get read/write access and send commands to the phone so I opened Root Explorer on the phone and then rand the superoneclick. As soon as the program mounted the phone with Read/Write I started clicking on the Mount R/W button in root explorer until it showed the app as having read/write access to the system/app directory. I tried deleting the Iron Man app and it said it was deleted successfully.
but then I checked and the app was still there loading root explorer agian then showed that the file was still there and had not been deleted.
Wow you managed to get root explorer to work? Mine just tries to obtain root, and crashes everytime i start it up now. I've tried to unroot, and uninstall and reinstall it. I used Linda manager to view the files on the phone, but like you if i deleted they would return on boot. That's why I think metro or samsung has some kind of media scanner that scans at start up, and it somehow reinstalls files, or prevents root. Can't confirm this yet because super user fails ;/
I've been trying also to get root. Programs often will think i have root access. as far as adb is concerned i do have root access till i dont something that requires it. I've been able to install root manager and look through some files. Im under the impression metro or samsung did install something odd, though im not sure the media scanner is it. Also the phone does not require root in order to install other-market software.
What do you mean programs "think" you have root? You mean you have super user? And what "programs" are you referring to? You can install root manager without a root yes, but in order to put it into "r/w" mode and delete the files from the phone itself, such as bloatware, you need root and Super user access. Most people here I hope are aware that you don't need to root to install "MOST" apps. There "is" apps that require root, and you cannot run them without root access.
Such as:
Titanium backup
Set CPU
Why do I want to root is like everyone keeps saying, to delete all the metro apps, and have "full" manufacturer control over the phone. That's the whole point of rooting. So far no one has rooted this phone PERIOD, or at least shown proof they were even able to. So any info you find regarding rooting please post it here.
Alright, so I tried what Mr. Parker did, and no go. Whether I ran super one click on Win 7 x64 (which was all in admin) or win xp, it would not install super user. In fact I noticed a couple of the files copied from super one click were already on the phone, and weren't able to be overridden. Which may relate to nand lock.

[Q] what is this weird stuff on my screen?

hi all,
i have problem with my galaxy tab 2 7.0 p3100, after i got updated from 4.0.3 to 4.1.2 via OTA i got black window on screen containing several phone information on it as you can see in the image i attached, i searched a lot in internet and xda found some solutions i tried all of them like
Solution: there are two ways of solving it. Pick the one you find easier.
Root access needed
Option 1.
Download from Market "Terminal Emulator"
Open it and type this commands:
su
echo -n ON > /efs/imei/keystr
sync
reboot
Option 2.
You need a root capable explorer. I recommend Root explorer, solid explorer or Es file explorer.
- Using root explorer locate the /efs/imei/ folder.
In that folder there should be a file called "keystr", but will most likely be missing in your case
- using root explorer create a new file called "keystr"
- also in root explorer open the file keystr in text editor and type "ON"
- make sure you save the file.
-reboot.

you need to be rooted to use those commands you tried earlier. If you're not rooted, try rooting and then perform those steps again

Yeah i know, either of that solutions need rooted device so my device had already rooted before doing any stuff like that ... If my device was not rooted then neither i could use su command in terminal nor open system folders and make changes by root explorer... Any other suggestion?
P.S although it is clear that both solutions are exactly the same but i tried both method each time on fresh install, hope to achieve some result but in the end of the day the same black box ...

Been reading around about this as it's been bugging me
(if you still have this, it's a factory mode (Apparently) )
found a link to these two (possible) fixes - now i know both of them are not for your actual device, but you could give them a go to see if you have any results. Probably best to make a backup first.

[Q] Root Many Android doesn't work for Kyocera Rise(Virgin Mobile) ICS 4.0.4

Now fixed, Solution grab the fixed batch from my second post, run it choose 1(normal), then run it again choose x(unroot), then run it for the final time and choose 1(normal), if all goes well titanium backup should allow you to use it(ofc you could check superSU and Superuser).
Original Post
Tried to root my Virgin Mobile Kyocera Rise C5155 on ICS 4.0.4 with Root Many Android, first try yielded a mount: permission denied (are you root) error, second try said it was successful but SuperSu didn't install, third try I chose charge only instead of mass storage and SuperUser instead of SuperSu but it didn't install. So I installed SuperSU from the play store and it said it needed to install the su binary but SuperSu couldn't do this, so I tried Superuser it could install the su binary but was given a permission denied by ICS.
So it appears this phone is no longer rootable with RMA. I had Usb debugging turned on and mass storage is my normal choice for connecting to pc, I have the proper adb drivers for the kyocera rise from their website, so from what I've gathered I've done everything to a T. went back an looked at the terminal saw it couldn't replace /system/bin/.ext (because it already existed) and I don't know why for the life of me that su is in /system/bin/.ext/.su but its there.
I used RMA v25. Any Advice or Suggestions would be appreciated.

Fixed See my Post Below for the Attached Fixed Bat File.
There was an oversight in the bat that neglected to clean up properly upon repeated root attempts, it didn't remove the /system/bin/.ext folder and the /system/bin/.ext/.su binary. I've fixed it to where it will remove those first (rm will exit cleanly(by this i mean it will exit returning control of the application to the bat, it will still generate an error ) even if the files aren't found which Means if they're not there it doesn't really matter)

Fixed yet again, titanium backup now reports Rooted, fix was to run the fixed bat choose 1(normal) let it reboot, then run the bat again choose x(unroot) then run one last time and choose 1(normal). this should clear any polluted data in /data for the flash and then root normally
Use this way instead
This is a much quicker and less messy way to root your rise. It says for hydo but works for rise too. This is how I did mine.

[Q] Softwinerevb -0.0mb stucked after updating the Busybox

Helo,im new here.. iam exploring the whole day exploring the web in getting root my device, but then after i succesfully rooted my device. i got a lot of errors like "unfortunately , the 'certain app' stop working". And when everytime i install the ROM manager, my device suddenly reboot on it self. I decided to have a factory reset on my device to check if the error will fix. And the error was actually fixed. I installed busybox pro, on the device and tried to update the busybox, and now my device has a 0.00b internal storage. I cant install any applications anymore. While doing self investigation, i removed also my Superuser privileges, thinking it would fix the issue. I also unrooted my device again. now im stucked -.- since i read about some forums that i just need to restore the busybox to the right directory. Anyone can help me? Iam running a tablet with Softwinerevb device name- i know there is a less support about this device. Running on a stock ROM JB 4.1.1. Well cross-fingers if someone could help me here.

I can install an emulator on it, and a root explorer. Is there anyway that you can provide some commands so i can gain root access using root commands and transfer the busybox from system\xbin to system\bin??
any solution
did you find a solution to this? I have a similar problem, but on a generic tv box. I have tried flashing a multitude of roms, but have only got 1 to slightly work
Try to change default install location to SD
Use ADB and try to change default install location to SD card. By this u can install some apps. Hope this will work for you.:highfive:
Late response, but I thought I'd put the answer here since I encountered it myself on a generic AllWinder/Softwiner tablet and found the answer on TabletRepublic. (Sorry, I'm not allowed to post links yet.)
There's something about busybox that prevents it from mounting the /data partition, so you don't have any storage available and all your personal settings vanish.
The solution is to copy busybox from /system/xbin to /system/bin. If you have ADB access (I did it from Linux) or can copy a terminal emulator to the SD card and install it do this:
Code:
mount -o rw,remount /system
cp /system/xbin/busybox /system/bin
reboot
Or if you can download RootExplorer.apk to the SD card, you can install that and copy the file with it.

Well it didn't for me. Also I want to know what I am doing with my tab and not just know that tapping this button will root my tab.
Have you ever tried to look at this site -> http://www.oneclickroot.com/device/acer-iconia-a1-713/. They featured this one-click rooting and it seems they can be trusted. I've downloaded and installed their software so no worries. Well, I'm also using a one-click root utility and it's always working. (just sayin')
The process of rooting a device is too complicated for those who don't have knowledge in Linux (like me), so your question about manually is out.
http://www.oneclickroot.com/device/acer-iconia-a1-713/
Well this one click root website was also a waste of time and didn't work either .
I may have to wait a little bit more before dumping this thread.
Rooting an android device basically means (for me) granting You (as the user) to do whatever you want to your device's system, hardware, etc. But what does root will actually do to your device that will cause you to obtain that superuser access? It's because of the "su" (Switch User) file used by Android and other UNIX-based systems that allows a process of switching of a user to be the superuser (or root user) that has access to the commands and file system, meaning those processes that requires root permission (root access or superuser access) need to invoke su. So basically the process of rooting will just push this su, a binary executable file, to the file system so that you can switch to the root user to give root permissions... And the Superuser application is just optional, but really required for some reasons, it serves as the "gatekeeper" of the su binary so when a certain command or application that invokes su will prompt the user by the Superuser app first before granting the root permission since becoming the root user can do whatever to the system which means it can cause the device to malfunction, etc... So what do you mean by manually?
Sorry for what I'd just suggest you that OneClickRoot waste your time...
Oh, there's a bad news after spending time searching how to root your device, read the news here -> [GUIDE] Firmwares, ROMs, CWM, Root - Acer Iconia (MTK) Tablets [ⒶⒸⒺⓇ ⒹⒺⓋⒾⓁⓈ]
Can't find a best way to root your Acer.
Well thanks for enlightening me on the topic, I hadn't really understood what really is su..
By manually I meant by using computer and tinkering with the files hands on.
Oh, and you needn't to be sorry since everything I tried didn't work. Sometimes I had root till the app was open while sometimes it existed until the next reboot.
Also looked at the link you gave and well, what can I say, it really is bad news and there sure is the risk of bricking my device.
Well thanks for taking your time.
