Hi,
The USB socket on my phone is not working apart from charging. I can get into download mode but do not want to risk flashing a stock rom via odin as if the USB fails mid-flash I will be in a far worse situation.
I followed the old rooting guide as I wanted to remain stock.
I've got my CPW stock rom and normal "secure" kernel (flashed back after gaining root)
I am rooted and have superuser app visible in the application list.
Is it possible to permanently unroot using a terminal editor or an apk from this position?
Should I just delete the superuser app? How can I delete busybox? Would a factory reset get rid of my root?
Really desparate so I can return my phone for repair!
Thanks
Bump. I have exactly the same problem :-(
In fact I don't even have the original rom or kernel saved and my phone won't charge
Are you trying to use warranty? Well, at last option you could try odin and going right and going wrong you should be fine. Going right you already know then answer. Going bad, since it wont boot, the tech guy from service center cannot see anything since it wont power on. He will have to fix and cannot proove that the phone was rooted.
please post here your info. I am trying to build a large DB about this issue, is it software or hardware related. There have been a lot of posts about this issue popping up.
http://forum.xda-developers.com/showthread.php?t=1188857
Kies recognised me as stock so I'm not prepared to risk flashing using a dodgy usb connection and doing software damage.
Please, does anyone know whether I can unroot just using the phone?

Fire up a terminal app, then:
Code:
su
busybox mount -o rw,remount /system
rm /system/xbin/su
rm /system/xbin/busybox
rm /system/app/Superuser.apk [I](this may error out with "file not found" - that it OK, only means Superuser app is installed in /data/app, perfectely fine)[/I]
Reboot to recovery and do a factory reset (wipe user data).
It's not perfect (leaves a crapload of orphaned symlinks in /system/xbin) but it's good enough IMO, I doubt they'll do a FS sweep for root remains.

Hello!
I did something really stupid. I rooted my Vibrant, and all was super easy and fine, but my home button was being unresponsive so without thinking enough did a reset on my phone. I wanted to make sure I covered my bases so I downloaded Titanium Backup and "backed up" all of the important things....call log, contacts, browser history, etc. etc. then did the master reset, but I don't think it worked. So now that I have done the reset it gives me force close messages on all of the main functions of the phone....dialer, web, you name it. Plus my home button still isn't working :/
So, the way I see it I have two options; risk sending the phone back to t-mobile under the guise of the home button issue....and maybe pay dearly for it (Superuser is still in the apps)
OR....
Hope and pray in the power of the XDA Gods, at least in order to get this to the workable category.
Thanks for any advice!
Are you able to get to the "Terminal Emulator" without it FCing?
You could boot into Clockwork Recovery and flash eugene's STOCK rom to see if that fixes anything.
hmmm, there's only the superuser and then the preinstalled apps. i did the one click root, so maybe that was missing the terminal app?

No its not missing, the "one click" just does rooting for you. You have go to into the market and download the application "Terminal emulator," if you're able to get that then you can unroot yourself and exchange your phone without T-Mobile ever finding out that you rooted. Or you could try flashing a stock ROM with Clockwork Recovery
got it! unfortunately though, every time i click market i get the force close :/ Meanwhile, I downloaded the clockwork recovery, but I'm definitely new to this, so where would I wanna go from there?
Thanks a lot by the way

Get Terminal Emulator as well; where do you want to go from now? You want to try to troubleshoot this problem or just unroot the phone and exchange it
Edit: Figure ill just make it easier.
If you want to troubleshoot: http://forum.xda-developers.com/showpost.php?p=7329357&postcount=2 is what you're looking for. Follow those instructions and your problems will most likely go away.
To unroot
Code:
su
rm -r /system/app/Superuser.apk
rm -r /system/xbin/busybox
rm -r /system/bin/su
Also remove apps that require root access.
Either one will do the trick. I would go with troubleshooting, the directions are simple. If it doesn't work then.. unroot and make sure that all the bloatware is there + no root applications so they wont be able to tell.
Here dude. It seems you can not download terminal emulator from the market, so here it is with the root file for good measure. Only thing is I hope you have a way to download it and get it to your phone. Gl, and let me know if you need any more help.
Just making sure we're on the same page.....so you meant to install clockwork on my computer right?
My market FC's every time i try to go in there.
Any way that I can at least get this guy to fly in under the warranty inspection radar and be functional is the way I'm wanting to go. should i attempt to load the files from the clockwork program into my phone? Sorry I'm so fuzzy on this.

Hey bro, here is a simple fix.
Download ROM Manager which I attached below and install it. Within ROM Manager you will have a option to install Clockwork, so go ahead and install in through ROM Manager. ( Clockwork gets installed on your device ). Then follow this link http://forum.xda-developers.com/showthread.php?t=740077 to download a stock Vibrant Rom. Follow the instructions on how to install the ROM, and you should be good.

Ok, so I accidently tapped forget for the "unknown" in super permissions and now when I try to type su in adb shell it says access denied. Any help?
I ve tried about 4 imulaters none will open.then I thought I had found the aswers to one of my issues, getting terminal imulator to work. But after ive installation and reboot just for good measure. I get the message that I cant install apps connected to the market. Im thinking maybe I should try unrooting and resetting the imei. Is there another way?
if youre getting a lot of fc errors, then odin back to JFD. make sure to use the .pit and .tar files. you'll be on official stock. then you can root/ update to official. anyway, its never a bad idea to go back to complete stock after major errors.
I tried this emulater su removal thing but it said that none of those fials exist. I am clearly rooted with su. Could it have something to do with my 17 digit imei cant seem toswitch back?
No and you seem to be pretty clueless to what they are suggesting you do. The easiest way to fix most problems with FC. Are using Odin to flash the OS back to stock. Several guides in the bible. Look under android development for the vibrant bible.
Maybe I should elaborate my issues so I dont seem so clueless, I dont have sync! I have tried kies, and odin but does didly squat w/o sync.
I dont have market access or OTA support. I just got back terminal after about 15 tries.
So im basically try to see which I get first; unrooted or stock reset. All of which seem to have some OTA necesity unless I can find a complete APK or termina access deal. Yea im a noob to
If your going to do anything to your phone such as rooting you need to download odin. There is a tutorial in the dev section under the vibrant bibal. Odin will restore your phone back to stock like it was out of the box. There are plenty of ppl willing to help on these forums so if you run into problems just ask. Every time I thought I screwed up my phone odin has saved my life.

My usb port is not functioning and I just received a replacement however SU is still installed on the phone and all the instructions I see to remove it require adb. I am desperate because I only have 1 day before I can send the phone back due to travel issues. Any help with this would be greatly appreciated.
Download root explorer, delete the .apk in /system/app and reboot. Enjoy.

Are you trying to erase the trace of rooting?
If your phone is rooted and you have been using apps requiring root, you probably have more than Superuser.apk in the system partition. su binary and busybox are for sure in /system/xbin or /system/bin (or could be /sbin). And then, symlinks and inid.d support? They can be easily detected. How about recovery? Can you flash the original?
Without adb access, it can be a real mess.
So, did T-Mo agree to warranty replace your broken phone knowing that you unlocked your bootloader?
When I placed the order for the warranty replacement, they asked me about physical or water damage, nothing software related. I recovered my original backup using clockwork recovery and it appears as if superuser isn't present however the bootloader is still unlocked.
Is there a comprehensive post that describes what carriers will do if they detect rooting or unlocked bootloaders?
I have a T-Mobile amaze but I have read so many difffering posts on this issue just from fellow T-Mobile customers alone. Hard to imagine they wouldn't honor a hardware warranty issue because of something a customer does on the software side. But what do I know....I still believe the world is a good place.

Hi all,
Firstly, I would like to apologize from my sheer noob-ness, I have done my best to try to find any solutions for my problem on this and other forums, blogs, Google, and Youtube videos but have not succeeded.
I have a Galaxy S3 i9300 International. About a week ago, the phone got stuck in the samsung logo loop-mode. The first time I managed to fix it by a simple factory reset, however once the battery ran out it once more started looping, and the factory reset would no longer work - now stuck in what I've later understood to be a 'soft-brick'.
Furthermore, I now had the following error message in the 'android system recovery' mode:
E: failed to mount /efs (Invalid argument)
#manual mode#
-applying multi-csc...
applied the CSC-code : unknown
successfully applied multi-CSC.
Since, I have tried to flash the phone with various ROMs, and successfully managed to get out of the brick stage by flashing the 'I9300XXALF2_I9300ODDALF1_I9300DDLEA_HOME.tar.md5'.
However, seeing as the /efs has not been fixed (and considering I have no backup), I am currently stuck in 'factory mode', and the status for my mobile network type, phone number, and IMEI's are listed as 'Unknown'.
a) Is there any way this can be solved, e.g. recover the IMEI number or any similar recoveries?
b) If not, is there any way I would be able to install and run Triangle Away to reset my flash counter so I can use my warranty in case the problem cannot be solved manually?
Thank you in advance.

Still haven't managed to fix it. Tried out the solution from http://forum.xda-developers.com/showthread.php?t=1703175&page=5
" Open terminal emulator and type as ;

rm /efs/FactoryApp/factorymode

chmod 0744 /efs/FactoryApp/keystr
chmod 0744 /efs/FactoryApp/factorymode
reboot"
yet the system didn't manage to find the 'FactoryApp' files so that didn't work ;[
For the problem with triangle away:
just maybe, try and flash a zip trough recovery, so that triangle away ends up in system/app with rw-r-r permissions. Should be installed at next reboot.
Then run triangle away to get official status, take out battery after triangle away finishes and before the phone reboots.
Reflash an official firmware through odin (preferably the one your phone came with).
Then rush to service center, play dumb, ask for a warranty backed fix.
Managed to install triangle away through the Wifi-connection so at least the last resort is taken care of. I downloaded Root explorer and it turns out my efs folder is completely empty, which I assume is a pretty awful sign? ;]
Gonna give it a day to find a further solution then take it back to Samsung with puppy-eyes and ask for a warranty.

Hey everyone, (It's a long story: But I would really appreciate any help...)
[I know the easy solution: Boot into RECOVERY MODE and factory reset the phone and if all goes well...DONE.]
I'm running on Android 4.4.(the latest I think its '2'), Stock Firmware, 4G LTE form MetroPCS, and able to get into a so called 'recovery mode' (you can only factory reset the phone) and download mode. I can't get into safe-mode. and I'm Currently stuck in a bootloop or a 'soft-brick'.
Here's what happened:
I've recently been messing around with the tether_dun_required on my LG in order to get it be able to tether WiFi to my laptop.
The phone was rooted using this method: [GUIDE] New Root Method for LG Devices
[ROOT was successful]
I tried various SQLite3 editing apps to try and change the tether_dun_required record in settings.db in data/data/com.android.providers.settings/databases but after looking ant the SuperSU logs I got this error: Cannot [mount or chmod] ... because the filesystem is Read-Only...
So, I decided to use ES-File Explorer to pull the settings.db file to my computer and modified it using SQLite Studio then I copied the files to sdcard and renamed the old settings.db to settings_old.db using ES-File Explorer. (all over WiFi) Then I ran ADB shell and got root using 'su'. I remounted '/' , '/data', and '/system' as RW using "mount -o rw,remount /" and etc... Then, I used the "cp" command to copy the files from "/sdcard/settings.db" to "/data/data/com.providers.settings/databases". I assumed you needed to reboot. So I rebooted the phone. AND....bootloop.
I was going to make a nandroid backup or atleast copy anything important out of the phone but: being a noob... I didn't.
I can't get ADB to run either of the Download or Recovery modes.
I know (have a feeling...) I can fix the phone if I can rename the settings.db to something else and the settings_old.db to settings.db but I don't have access to the filesystem because I can't start ADB.

Thanks you for you reply. I have one question though, I have no idea if my bootloader or my kernal or any of that is 'unlocked' I only rooted my phone. If I try to flash aroma fm and they are locked or something would that actually really brick my phone?
ALSO: I don't have an SDCARD... I don't think it's possible to flash anything then? Because flashing from the Internal Storage might brick the device. right?
ALSO: I don't think the LG Optimus F60 has ARM Neon support... & the "Recovery mode" doesn't have any flashing support. It's all STOCK.

well damn, if you have a custom recovery usb-otg you can make a flashable zip that runs some shell commands.
flashing wont brick a device. putting unsigned boot/recovery imgs usually bricks locked devices.
as with all lg devices, there is download mode to load stock firmware/updates. [LOL apparently I can't post outside links yet even, if their a quote...]

That's RIGHT! But, sorry for the noob question: What is a custom recovery usb-otg and how do I make a flashable zip that runs some commands? (For example: maybe one that just runs the commands but doesn't actually change the recovery software or the boot just one that can rename the files?)
Also, I don't think it would work but, would flashing the recovery to stock not delete any data, and have the phone be able to boot?
If it's too much to explain that's okay just show me some related posts that can show me how.

I'm not sure, because the phone already has the factory boot and I haven't flashed anything into the Boot Partition. It's probably an error that happens when it tries to validate the settings.db or the permissions it has [chmod or that its mounted read write]. [To my understanding] what TWRP boot loop fix does is install fastboot then the custom recovery and the stock boot again. Which should do about the same thing because the phone is already stock. Right?
Would installing a custom recovery then allow me to access adb or the filesystem? (If so any recommendations?) Or how would I run a script from download mode?
Thanks for your time.

you only need to flash the recovery. not the boot img.

One last question (Need to make sure...): I have fastboot.exe from the SDK tools, so all I need to do is:
1. Connect the USB
2. Boot into Download Mode
3. Run fastboot flash *.img
4. When finished unplug the USB and take the battery out.
5. Then boot back into Download mode or Recovery Mode to get TWRP?
6. Then try to see if I can get ADB to work?
Also, sorry for all the questions: But If I ever needed to, will a factory reset delete TWRP or will I need to flash it again with the Stock recovery?
Thanks for your time. You are awesome.

i was curious and tried lollipop (i think i tried both 5.0 something or 5.1 something or just one of them ended up working) but the camera was completely non-functional so now i need to go back to the phone being how it was when i bought it.
the firmware i've installed on the phone right now is MS39510G_00 (i think "MS39510G" is the actual identifier of the firmware, and the 00 is probably not useful for anything; the site i got it from maybe just appends it for some reason). but this firmware doesn't seem like what the phone came with or i'm not using/not doing everything i need to to restore it back to normal.
couple of things that strike me as odd and make me think that i don't have the right firmware or just didn't do something right:
there's a weird white area at the bottom, which i think was transparent and took on the color of the wallpaper on the phone when you just bought it & didn't mess around w/it
some of the icons are just the generic green android icon. a lot of apps have this same icon instead of different icons of their own
the lock screen seems also seems kind of different. it doesn't look like the lock screen of a new lg f60. maybe i was using a custom lock screen (i doubt it, but it's possible) but still it doesn't look like the standard lock screen to me
how do i restore my us metropcs lg f60 phone back to stock?

Hi I need the combination and firmware for the Samsung Galaxy SM-J337PVPU3ASC1
I flashed it with a combination file.. but now I'm stuck in the factory binary mode so I need to flash it again
with the stock firmware or whatever to get it working again
Was trying to do a google bypass and kinda goofed because I couldn't find the right firmware :/
If anyone could help me out I'd appreciate it!
I did same, on accident though, trying to bypass fpr lock after factory reset...honestly i think this phone is ****, being as nobody seems to know anythang bout it. I called asurian and got free replacement.

I did the same exact thing, so far I've figured out that with that being the newest flash of combination we upgraded the bootloader to binary 3 now, the only firmware that will work is going to be the PVPU3ASC2 which is April's update but online you have to have membership or pay to download, unless that's all a scam? I just did this same wipe on a j327p and had no problem going up from binary 2 to 3 and flashing stock ROM. But from what I understand there's a way to just turn factory off in the combination ROM. I've spent hours pouring over different avenues to go. I was going to change device id to j337U being the unlocked version but I'm getting stuck on gaining SU permissions in the Shell with this new factory binary ROM. I can get adb shell while it's running and side load from recovery but nothing installs or flashes. I believe it's running a sort I emulated VM instead of running ON the phones persistent memory.
FINALLY someone to talk to about this specific problem. It was my fault flashing the U3 combo instead of the U2arj2 I should've.
Attaining root J337p? Dirtycow?
To gain su permissions after reflashing stock have you tried using the dirtycow exploit. I have found it to be an almost fool proof method to attain temp root and for flashing twrp or cwm. Depending on the phone you may have to modify the source a bit but basically jus go to github and download the dirtycow zip or if your using Linux then use git clone and clone the Repository then extract it rename to whatever you want i use the simple dirtycow. put that and accompanying files on the root of the phone (/sdcard) . now use ADB push to push it to /data/local/tmp. Then ADB shell cd into /data/local/tmp and chmod 777 *. Once thats done depending on your phone its gonna be a little trial and error but use ./dirtycow /system/bin/applypatch /data/local/tmp/(the name of your dirtycow applypatch file). Then the same process with app_process or app_process64 depending on the phone. Reboot. That should take SElinux to permissive. Here is where things get tricky. ./dirtycow /system/bin/run-as /data/local/tmp/(name of your dirty run-as file). If you have the exact dirtycow applypatch file for your phone then proceed to thw next step otherwise do whatever mods you gotta do to get your file right. Now run-as exec ./(dirtycow)-applypatch boot. Once that is finished run-as su and presto you have temporary root to do whatever you feel like. I do the next step manually if youd like to. Download the appropriate twrp for your phone name it something memorable like twrp.img and move it to the /sdcard root of your phone. now su dd if=/sdcard/twrp.img of=/dev/block/bootdevice/by-name/recovery. Reboot to recovery and you should be free to flash a permanent root method like chainfire supersu or magisk. And that is that. But i warn you not all phones store the recovery image there you may need to search around a bit. I use su ls -al /dev/block/bootdevice/by-name or cat /proc. Between those 2 i usually can find where it is. I claim no responsibility for bricked phones. Thank you. I will be doing this to my j337p later today ill let you know what i come up with
Ps. If your phone is relatively new its more than likley it has a property called dm-verity which is enable that is a huge pain and causes encryption to fail while flashing. There are .zip files online i believe called dmverityopt.zip or something to that effect i suggest flashing that before and after any custom rom flash. Or a custom kernel that doesnt have that problem.
