[Q] Can you unroot without using a PC?

I'm new and I hope I'm not posting this in the wrong place or re-posting an old question, but I have been searching on this and other sites for days and haven't been able to find anything pertaining to my question, so sorry in advance If I'm not posting this correctly.
I have a rooted epic touch with rogue boot loader installed and UnNamed rom installed. I really liked the way it was running until I had some kind of malfunction happened and now the battery charge light won't shut off and the battery drains within a couple hours of standby time. the phone is only a couple months old and would like to take it to the sprint store as I'm assuming this is an obvious hardware issue. My problem is that my pc doesn't recognize my phone anymore so I can't flash back to stock and get rid of root, voiding my warranty. I have tried uninstalling and reinstalling kies and stand alone drivers multiple times with no avail. I've tried with the battery and sd card removed and have also tried on multiple pc's (2 win7 and and xp machine). every time it says the drivers weren't installed successfully and to replace the device being connected.
My question: Is there a way to revert to stock off of the internal memory of the phone? I know there are zip roms you can flash from the boot loader but I was wondering if there was a way to flash a rom from zip and install the original boot loader as well as get rid of root? Any help I can get would be extremely appreciated and again I apologize if I am wasting anyone's time by asking in the wrong place or re-asking a question.

Ok so I downloaded the Calkin's_Stock_Rooted_EK02_ROM_v1.0 and got it on my sd card via dropbox. Flashed and now have a stock rom on it which I think is a step in the right direction.
The only thing is now I have clockwork boot loader and still rooted. and still not recognizing on pc. anyone know of an unrooted zip with original boot loader?

I couldn't get my PC to recognize either of my 2 E4GT's, each due to a different reason, both issues were resolved by going through each step in sfhub's debugging checklist:

This post is for the FAQ section:
Why is the install stuck waiting for device to be connected?
Your phone isn't being recognized by your PC as an Android device.
When the drivers are installed and the phone is properly recognized, you should see the following in start->run->devmgmt.msc
Code:
Android Phone
SAMSUNG Android ADB Interface
Modem
SAMSUNG Mobile USB Modem
Until you get the SAMSUNG Android ADB Interface to show up, neither ADB nor this script will work.
Here is a debugging checklist:
1) dial ##UPST# (##8778#) in the dialer and verify AP (or ALL) is checked (if CP is checked, phone won't be recognized as an Android device)
2) restart the ADB server (choose Option G to stop the server, it'll get started automatically by the script)
3) verify USB Debugging is ENABLED
4) verify USB drivers are installed (Win7-64bit see below)
5) try a different usb cable
If you are in Win7-64bit try changing the default install location for the drivers:
If you see an error like this:
Try running the CMD prompt (or e4gtauto-sfx.exe) as Administrator. Right-click on the CMD icon (or e4gtauto-sfx.exe) and select "Run As", then select Administrator.
If that doesn't work, try disabling windows firewall.

I went down that list and everything seemed to be in order but still no recognition by pc. I kept uninstalling and reinstalling the drivers and switching usb ports and it finally installed the drivers successfully long enough for odin to recognize it and to flash back to stock. As soon as it was done the machine stopped recognizing it again. Lucky break I guess. So I can now return it to sprint and deal with the hardware issue.
I would still like to find a zip file like the tar that I flashed that installs stock recovery and non rooted ek02 rom and kernel from cwm, if that's even possible.
Thanks Godswrath, for helping me out.

You could use wifi explorer to get files on to sd card and mobile Odin to flash the tar file back to stock....

Lol....I am a noob.
They make a mobile Odin? That would have saved my like 4 hours....

can't connect phone to computer

even after updating to 4.1.1, i still can't connect this thing to my computer, could it be a usb problem?
it endlessly says 'connecting' on kies, and other times it'll say 'hardware id missing'. then other times the drivers all install correctly and states the the device is ready for use, but on my phone a notice comes up titled 'Attention', stating that there isn't any software on my computer that can recognize the device. sometimes it HAS WORKED on ics, but no luck so far after my recent update.
what's wrong? it's been like this since the moment i've purchased the phone, but the 'Attention' notice was new after I updated to jb.
edit:
the attention notice says:
"Unable to find software on your PC that can recognise this device. Service pack 3, Windows Media Player, version 10 or higher, for Windows XP or Android File Transfer for Mac OS must be installed.
You can download and install PC Kies from (URL) in order to sync data with your device, back up data, and upgrade your device. (Windows and MAc OS are supported)."
im running windows 7. also, i think the hardware ID missing notice is linked to the attention notice.

Search Google for Samsung Galaxy s III drivers (sorry don't have a link) nd try from there.

Uninstall kies completely and download a fresh install and go from there.

Mtp error fix
I found a solution and you do not need to do a factory reset.
1. Uninstall Kies and Samsung USB Drivers
2. Go to My Computer Properties -- Device Manager -- Look For Any Android or Samsung devices.
3. Right click and select Uninstall.
4. Check "Uninstall drivers..." option.
5. After uninstalling, plug in the phone. It should work now.
Worked for me. Hope it works for you guys as well.

Windows doesn't "see" note 2.

Good Evening folks,
I'm posting here after spending the better part of 2 days trying to figure out why this doesn't work.
So, i have the following:
model: GT-N7100
Version: 4.1.1
Build: JRo03C - ALJ1
I run a PC with windows 7 and also have a laptop with windows 8.
Now, initially i only wanted to root my device to install an addblocker on it and get rid of some bloatware. so i went and got samsung note2 toolkit here on XDA. (also tried others)
but no matter how i tried the pc (nor laptop) would see the note 2. it would plug in, it would charge... but windows ignored it otherwise.
i have tried al 8 of my USB ports on the desktop, and all 3 on the laptop. none of them work
3 different USB cables.
re-booted more then times then i can count.
i have manually installed the samsung drivers.
i have tried installing the windows MTP Porting kit
all to no avail.
So before i can even START to root... i need it to to play nice with my machines... anyone have ANY suggestions on what the hell is going on here.

If your main priority is to root then use exynos abuse

hi,
Thanks for that! found the APK file and got it on the phone through email and it's rooted, so my mission is accomplished...
but my problem still persists:
why oh why wont windows just play nice with the phone?

Did you install Kies on your PC? That program needs to be open when you connect your phone and then it will install the needed drivers.

Or install the drivers using the Note Toolkit http://forum.xda-developers.com/showthread.php?t=1923956

Does it show as an unknown device in windows under device manager?
I'm having the same issue but I have a suspicion that its the USB port on the phone itself as my gnex can use the same cable/USB port and show up as mtp.

my windows is same

My Note 2 N7100 is 'seen' by my windows 8 machine, but it doesnt seem to copy/ paste anything. Pops up with an error. The same happens on a Mac Lion machine. Installed the Android File Transfer app, but the moment I connect my phone, it pops up a message saying please restart your device so that it can be detected. I am tired of transferring individual files over AirDroid Any help?

What's the error message?

Happened to me before, un install kies on your pc reboot, download from Samsung website and install again, should work
Sent from my GT-N7100 using xda app-developers app

first of all I forgot to mention that this should've been posted in Q&A section
for the problem try the following steps. after each one of them try connecting again. keep net disconnected while you follow the steps.
if it starts working then stop other wise continue.
1)use a diff comp, but you already did that , use a different cable, you didn't mention it
2)try uninstalling drivers via programs and features.
3)try installing drivers - preferably via mskip's toolkit
if you have windows 7, then directly install it
if you have windows 8, then first disable driver signature enforcement via this guide's last question.
4)try re installing windows. if you don't wanna do that then
open device manager
in view -> show hidden devices
delete each one that says samsung, note ii or note 2, android, google, adb, gt-n7100, n7100
this will ensure that you truly remove drivers
follow step 3) after this.
Hope I helped

All the usual and helpful ideas have been listed and you should definitely work thru those to make sure you are not missing something obvious but critical. I also use Win8 (64) and all was well with my Note2 showing up as an MTP device and wll working then one day, seemingly spontaneously, it suddenly didnt! When I would plug my Note2 in, Windows would give me a USB error telling me it could nto recognise the device! To cut a long story short, I tried my wife's S2 and IT appered fine as an MTP device happily enough, so that ruled out the cable, the port and the computer/OS.
I then tried my Note2 on my laptop, and once again it came up as USB error, so the problem was following the DEVICE around....
After a lot of googling, I tried on thing that fixed it instantly:
On the phone, go into Settings, Security and delete all the "Device Administrators" which in my case was just my Email app. That did delete my email account from my phone (contacts, email etc) but didnt matter as phone is just a dumb client to the mail server so no loss of any real data.
Once removed, I then plugged phone in and BOOM! MTP device happily appeared! I then went back in and just re-added my email account and re-activated Device Administrator when asked. Working ever since.
Not saying this is your problem, but it was an eye opener to me that the Device Administrator could 'lock out' the USB connection of the device....
Hope this helps.

I would also recommend checking your Windows Update log - especially if you have it set to automatic updates. After I installed the drivers off of the Samsung website, Windows Update tried to "Update" my drivers to an older version (I do manual Windows Updates). The first time it asked, I let it, and my phone couldn't connect anymore. Once I stopped that silliness I stopped having problems.

same problem usb not conecting with my pc windows7
all this is my same problem which I facing help me about how to slove this matter

I was having the same problem, but I was using a USB cord that I had from my old phone. Switched to the white one that came with my Note 2 and it started working.

[Q] Galaxy Ace II cannot be detected by PC (XP/W7/W8)

Hello, I'm the new guy, kind of (I'm new to this forum but somewhat a technological handyman, so to speak).
I had recently obtained a Samsung Galaxy Ace II, everything was going good on the phone, hell, it's what? Two years old now? Anyway, I noticed the immense trouble I've been having trying to get several Windows PCs/laptops to detect anything from the phone, no driver updates, installations, not even from the trustworthy SAMSUNG Kies application. It is becoming a real problem as I really want to keep this phone, root it, installing several ROMs as I go along, but no, the computers won't even allow me to access the contents of my SD card through USB.
(Note: I have manually downloaded and installed SAMSUNG USB drivers and pooft, still nothing!)
I have tried quite a few methods to allow the PCs to establish a connection with the phone e.g. Dialing "*#7284#*, accessing "PhoneUtil", choosing "PDA" as the good mode, even switching to "MODEM" then back to "PDA"; Uninstalling/Reinstalling drivers; Attempting Kies.
I guess I am on the look out for a new-ish phone to replace this, which saddens me as I love being able to root, install various ROMs, Kernels etc, personally I like this phone too, more than my Spica running ICS (couldn't be too hard though, it wasn't stable whatsoever).
If anyone on this board could find a solution to this problem for me, I would be ever so grateful, I don't doubt it though, I love the work of XDA. Thank you.

Turn off the phone with no cable attached, press volume down, home and power at the same time and then volume up to put it in ODIN mode and connect it to the PC (use windows vista or newer so it auto installs the driver) It should install something like Samsung USB serial device. Tell if it works

Do I have to load it into ODIN mode whilst Odin is running on my PC?

For this test you dont need ODIN on the PC. Its only to see if the PC recognizes the phone

I just tested this and it appears not to be working, whatsoever. Is it necessary to have all SAMSUNG USB drivers installed on the PC?
Thank you for the idea, though. I just really want to root/mod my phone, ugh.

Windows should auto install the drivers. Connect the phone to the PC and see in device manager if there is something like an unknoen device or Samsung USB device

Thank you for the help, although my problem is not dealt with still. I have completed the steps that you had suggested, thoroughly and repeatedly, yet there is no hope for a permanent, or even temporary fix for my mobile.
Windows isn't displaying any correlation between my PC and phone, no driver software auto-installs and no sign of the device being located in the Device Manager, not even under an "Unknown device".
Is this a problem for most Ace II devices? Or am I missing something that is too obvious to consider so seriously?

Porobu once told me something like:
1. Uninstall kies and sammy usb drivers
2. Install kies again, it should promt to install USB drivers.
3. Plug in phone to pc in DL mode.
I'm not sure what you mean in your 1st post so im assuming you have yet to try this. Works for me

When do I plug the USB into the phone and boot my phone into download mode? As soon as the drivers are installed via Kies?

After kies installation complete(dont have to open), boot phone to download mode, connect to cable and plug to pc

It sounds like a broken microusb port but try something first.
Download ubuntu or any other live cd linux distro
Boot it on your pc. You dont need to install anything.
Open a terminal
*Plug the phone while it is turned on to the PC
Write in the terminal 'lsusb' without the quotes and press enter
Something like Samsung android device or MTP device should appear.
If it doesnt appear power off the phone and go to odin mode and repeat from the * the steps

Can't load recovery on TabPro 12.2

I want to upgrade my tablet with Lineage OS 14.1, so first i have to install a recovery.
My tab sm-t900 is original with android 5.1 on it and it has become slow.
When the tab is turned on, it's recognised by my windows 10 pc and odin. When the tab is in download mode, it's not recognised by my pc, so also not in odin.
I use the original Samsung cable and tried other original ones. I tried uninstalling and re-installing kies. I installed the latest windows 10 drivers for the tab, which i downloaded from the samsung page. I have enabled usb debugging in developers options.
I tried it on a windows 8.1 laptop and on a windows 7 pc with all the suggestions i described, but i can't get it to be recognised when in download mode.
I noticed the blue line 'secure download : enabled' in download mode and wondered if that may be an issue?
I have searched for a long time by now and don't know what to do anymore. Does anybody have a suggestion? Am i missing something?

It seems like my problem is the locked bootloader, but i can't figure out how to unlock it. In developers options there is no option to uncheck OEM.
How can i see if i have the lollipop bootloader?
