Hey guys
I noticed that many people are asking around for a way to unroot their phones, and you hear alot about flashing back as a solution for unrooting, but for me that was abit not preferred. So here is a way to do it quick and soooo easy and you don't even need a computer to do it. We start:
1- From the android market download (Terminal emulator) and run it.
2- Once inside the shell type in these commands (you gotta press enter after each line)
su
rm -r /system/app/Superuser.apk
rm -r /system/xbin/busybox
rm -r /system/bin/su
and Voila, your phone is now unrooted. needless to say that you should also uninstall the terminal emulator as well. Hope this is useful.
Thumbs up! Someone should have posted this quick and easy method earlier.
Meaning we wont have any warranty issues with Samsung if un-root and send back to service center? Thnx.
well, first of all you need to have the same stock rom shipped with the phone (or the officially upgraded one via kies). Then you should unroot it, then in recovery mode you need to clear cache and do factory reset. and format the internal storage (and of course remove SD card if any) then it will be in the same condition when it was shipped to you. Thats how you avoid trouble with the warranty before sending your phone back for service or replacement.

Wow....thnx...this make the whole rooting process sweet.
Great stuff man, well done.
Nice tip!
If you unroot using your method and then wipe the phone completely (cache/factory reset) then place ClockworkRecovery onto internal memory as update.zip and reboot in recovery and make a nandroid backup (doesn't need root) then carry on, should you need to send it in for warranty just restore the nandroid backup and it will be unrooted, stock firmware and fresh You might need to flash the stock modem back though if you change

Hey guys, glad you liked that. And indeed using clockrecoverymod as update.zip is a great tool, no root or whatsoever.

After unrooting my sgs, uninstalled all as described, found strange app under settings > manage apps called "com.noshufou.android.su", default app icon, just 8 Kb...
googlin' found a site
(wwwdotmarket4androiddotcomslash-stock-android-2-1-apps-list) that says:
Superuser.apk com.noshufou.android.su yes 16549 Remembers ‘su’ settings
(yes is "safe to remove")...
Anyone knows if this is right?
May I remove it from apps?
Thx
Well I must say this is so strange. But you i'd bet it can be safely uninstalled. If I were you i'd make sure to do factory resetting once more and clear cache again.hope that helps.

Well, technically speaking this method should wwork on any firmware as it is shell based. I tried it on JF3, JM2, and JP2. Plus you have nothing to lose it is 100% safe so you can try it, if it works , fine, if not no harm done.
This method have ruined my phone.
After step rm -r /system/app/Superuser.apk my phone hang and displayed the message "Can't write to readonly memory" and now it refuses to boot again. Have tried removing the battery. I have also tried to hardreset but i don't even get to the screen to select a hardreset. The phone starts but don't get passed the initial samsung splash screen. If anyone have an ide how to fix this please help me.
WARNING! Be really carefull before using this method
Well, sorry it didn't work out for you. But to be honest this should be the safest method as the other option is to flash your phone already to another stock firmware. So as now this method apparently failed and you got a wierd situation where some of the system files were ruined, you can just try to flash the stock rom files using odin.
The stock firmwares and the tools you need (odin) together with a tutorial on how to do it you find in the following link
http://samsung-firmware.webs.com/samsungi9000.htm
good luck
it worked fine for my sgs did it just few minutes ago, but added reboot in the end
not working
Iv entered these codes, and after I hit enter each time it says file.not found. Am I doin something wrong
Hi, my SGS is using XXJPY with voodoo kernel.
Can i use this method on my SGS?
And should i firstly remove the kernel or the commands can be applied directly?

I have a stock 2.1 defy with the 2.51 rom (i think). all the mod i did was root the phone using super one click, the phone ran fine for a few months until i experimented with titanium backup and deleted google talk etc. i found out that (too late)doing this would cause the android market to stop downloading and updating my apps. To remedy my situation i tried installing google talk service.apk back to system apps. first by copying the file to my sd card and pushing it to the system file using terminal emulator. after rebooting my phone is now bootlooping. i tried removing the battery and just after i insert it it would go immediately into the bootloop phase. tried using recovery (volume down+power) and wipe cache and reset, still no go. last resort i tried is after wiping i tried installing cm7 but the installation was immediately aborted. please help, right now im close to tears, i didn't know that it was this hard to mod a defy. my previous phone was a wildfire and modding it was pretty easy.
What happens when you turn the phone on? Does it start in the bootloader? Is it stuck in Motorola Logo?
Try to wipe data/cache again and see what happens.
As well you might want to go ahead and download all tools needed to flash an sbf. Because if worst comes to worst your going to have to flash one

the phone turns itslef on automatically when i insert the battery, white moto logo first then bootloops in motoblur animation.i can go into bootloader mode by pressing up and power before inserting the battery. i just wished i hadn't played around with titanium backup. i already downloaded the necessary files to flash a new firmware. hope i learn to do it properly.

Hi I have the same problem,I just tried to flash the Barebone 1.5 ROM.
My Defy was stock,I just root it and made a backup with clockmod before I did as discribed here:
Installing (Rom wipes data/cache partitions)
1. Copy Barbones to sdcard: Barebones_15-signed.zip.
2. Boot into recovery (make a backup ?) and restore nandroid: 3.4.2_177-Nand.NORDIC_DEBLUR.zip.
3. Still in recovery, select install zip from sdcard -> choose zip from sdcard -> Barebones_15-signed.zip.
4. Reboot system, first boot will take time as it builds the dalvik cache; wait for the background to load, and enjoy Barebones.
- Use Easy Installer to install any apk's you feel are missing.
- Removed.Stock.Apps.zip
-- Removed Apps Must Be Copied To /system/app Manually - Remember To Set Permissions & Reboot
To downgrade back to Eclair; just flash the Eclair sbf you where using beforehand; thats it.

after Reboot it just shows Motorola,I can access Recovery Menu stock one and custom,tried wipe restore factory settings and wipe cache but nothing helped!
What version where you coming from ? Eclair or Froyo ?
Btw factory reset and wiping the cache doesnt do anything in these situations.
Did you restore the Nandroid provided ?
Also cant lie only thing I did not test was coming straight from an Eclair build.
I used the Korean Froyo sbf as a starting point; but I'm testing it now.
Got it alive again with this steps.
No wonder why u're stuck on motorola logo.
Let me break it down for you.
Make sure you have motodrivers installed or install them here.
And install the RSD Lite too Here
Turn off your phone, hit the power+volume up together.
Wait till u're in the bootloader.
Open the RSD Lite, u phone should be detected so u click on "..." select the .sbf u downloaded from here
And flash it.
Wait till is over, and your phone should be good again.

I used this .sbf
But I still don't know what went wrong,I did exactly as discribed in the TUT I postetd above!?
Well if you flashed that sbf you wont be able to downgrade back to Eclair anymore.
However; yes doing that will fix it.
Is it not good that I flashed this .sbf? I got the phone just 2 days ago I think it already had the newest firmware etc.!?
EDIT: But something is wrong with my Wlan connection it is very slow and always loses connection
I doubt it came with Froyo seeing as they are all leaked builds.
http://forum.xda-developers.com/showthread.php?t=966537 <- Read up
Just means you cant go back to Eclair.
Ok so you wifi is slow ? Are you even using my rom now; because you flashed 3.4.2_155-Stock.CEE_DEBLUR.sbf.
I cant see your phone so you have to tell me what your using.
Yes I just flashed the sbf nothing else,and before I just did what I read in the instructions from the Barebone 1.5 Thread.
1. Copy Barbones to sdcard: Barebones_15-signed.zip.
2. Boot into recovery (make a backup ?) and restore nandroid: 3.4.2_177-Nand.NORDIC_DEBLUR.zip.
3. Still in recovery, select install zip from sdcard -> choose zip from sdcard -> Barebones_15-signed.zip.

I tried this sbf before 3.4.3_11-Stock.UKTmobile_BLUR but it always failed thats why I tried the other one
So your not using my rom now - the sbf overwrites everything.
Ok sorry Im a noob^^ I just wanted to have all this blur stuff removed etc and your rom seems just perfect for me.
I have problems now with the phone and I really wished I would never had tried this.
I cant boot into recovery mode anymore with clockworkmod, I rooted my phone again installed clockwork but the screen stays black after the Motorola Screen came up when I try to make a recovery boot with clockwork.
cause I wanted to restore the backup I did with clockworkmod before I messed it all up,would that make my phone like it was before or not!?
I doubt you will be able to get back to your backup simply cause I dont think its Froyo.
So do this:
1. Boot into bootloader (power + volume up).
2. Flash 3.4.2_155-Stock.CEE_DEBLUR.sbf again.
3. While its rebooting after flashing hold volume down to goto stock recovery.
4. Do a factory reset.
5. Root your device using superoneclick http://forum.xda-developers.com/showthread.php?t=913709
6. Reboot.
7. Install 2nd Init Recovery http://forum.xda-developers.com/showthread.php?t=1032212
8. Reboot twice (to finish installing recovery).
9. Reboot into recovery - wait for blue led then hit volume down.
10. At this point you can try to restore your backup or flash a rom of your choice.
If you try your backup and it does not work you will need to start this process over.
Ok thank you so much fritolays for your help! I will try this tomorrow and post back if I had success or not!
greetz!
EDIT: Couldn't wait to try it and it worked! I took the risk and tried to install your rom again (restoring my backup didn't worked anyways 'cause clockworkmod didn't find the backup but it was still in the same folder it got stored before) works like charm as far as I could test it. But now I really have to go to sleep!
Big thanks again fritolays without your quick help I would still try to get my Defy to work without any success! and THANKS! for this great rom!!!
EDIT2: I don't know why but I have problems with the phone since yesterday when I first flashed another ROM,I always have Network Connection Problems now! I can't download anything from the market if I get to the market! 'cause normally it says no network connection! It worked fine for like 20minutes after I got it to work with ur method u told me above then it suddenly took very very long to download an app. Never had these Problems before,I also have very bad Phone Signal and most of the Time I can just make Emergency Calls and I turned Internet Connection OFF for mobile network (like I did before when it was stock) but sometimes I still can go online with Wlan turned off so this is really ****ed up 'cause I have no internet plan with my mobile phone!
But with your ROM the phone is really flying,I did a Benchmark Test before and got 1100 Score and by just putting your ROM on my Defy without any overclocking or something like that I got 1275 Score!
EDIT3 I found the direction it was clockworkmod/backup/ now
I did a wipe factory reset and a cache wipe and now restoring it I really hope everything is like it was before all this!
Ok this got me to the Bootloop Problem again so I did again all the steps u told me and instead of restoring ur ROM I restored my backup wich was now in the right direction,but it is also ended up in Bootloop!
EDIT4 If I try all this with ur ROM it works,is it because of the Froyo .sbf I flashed that I can't get my backup working!?
I get this Error Message after my phone booted with ur ROM maybe that is one of the Problems I have? "Sorry,the process android.process.media got suddenly closed try it again" I had to translate it so maybe the message is a bit different in english but thats what it says generally.
So everything worked great again,I go into Market to download TitaniumBackup (like I always did) then as always I apply the new Busybox Install TitaniumBackup suggests everytime I start it and the Wifi gets slow already by downloading Busybox. Then I tried to go to the Market again and Network Error, I get the feeling it has something to do with this app or the Busybox installation TitaniumBackup is doing!?
I don't know what it is but it alwys messes something in my phone up and I get Wifi Probs!??
EDIT5 I tried another ROM now "xd1 ** new ** ver 1.2" and everything worked fine! I downloaded Quadrant and a Antivirus App just to test it and everything was alright so I tried TitaniumBackup again (the Free Version as always) and guess what the download got fast till 42% then stuck and now I can't download anything again from Market it is very slow and then the downloads got canceled! wtf is wrong with this app!? I need it for all my Apps 'cause I did a backup with this app but since I flash custom ROMS it always does this bull**** when I download it from market!?
update..got my defy unbricked by following Higgsy's step by step method. installed a 2.51 SEA sbf in the process. love the phone without blur. now im thinking of upgrading to a froyo rom, which do you guys think is the best? based from reading the posts here i'm more confused than ever. sbf's here and 2nd init that??? not to mention a fixed sbf?? i really can't understand these terms and the more i read the more i got confused. Could you guys help me in laymans terms the proper process for upgrading to froyo and which rom is you think is best??
I was trying to install a new rom on my Desire Z, following the directions here, but something went wrong somewhere and now I can't mount /data. I don't want to go any further in the rom installation process, as I'm afraid to brick my phone. The same thing happened to me while upgrading my Windows 6.5 phone (unexpected problem during rom install) and I ended up with a brick (corrupt bootloader).
I have found several threads here discussing the same problem. However, all of them use highly technical language and seem to be advice from experts to other experts. There are a lot of terms I don't understand or only understand partially, like nandroid, parted, hboot, and so on. Everyone assumes too much. Can anyone explain the procedure in terms a novice can understand?

"Mount" data to flash a rom? You sure? Looking at the link you provided just says place on sd, wipe, flash. Where exactly are you stuck or am i just missing the obvious.
The /data corruption occurred halfway through the upgrade process. I'm not sure what to do, so I stopped and asked for advice. I kept going the last time I had a problem, and got a bricked phone for my trouble.
The only "data" I see in that guide (Same one I used in fact), is the comment bout doing a "Factory Reset/Wipe Data" which is what it says, says nothing about /data/ partition, just to do a full wipe.
Naturally you do this from recovery, not from within an app or while the phone is still booted into normal usage.
So, wiping the phone will fix everything? And then install cyanogen? Sorry, just want to be totally completely sure.
Aye, indeeed, as KB said, full wipe, then flash new rom.
OK, thanks! I was just reeeealy nervous about the "wipe the phone" part. My phone still sort of works now, most programs not available, but Google Maps and the telephone still work...the most important parts of the phone as I travel a lot.

Factory Reset/Wipe will only clear the internal partitions ( /system /data /cache ) , and additionally if you choose Dalvik Cache, then that as well is usually good to do with a brand new rom.
It will not wipe your radio, hboot, recovery, etc, just the system-related areas for roms.
Generally speaking:
Factory Reset + Wipe Cache/Dalvik Cache
Flash CyanogenMod
Flash the Google Apps Zip specific to that CM version (as CM doesn't come with Google Apps by default)
Reboot
Just remember that doing a backup before doing anything to your phone like above is available, as a factory reset and such will wipe contacts and settings and so forth unless you got a google account setup to restore them (or using something like Titanium Backup on an already rooted phone).
OK, I was following the rooting guide, as that must be done before installing cyanogen. I performed all the steps to "reboot". Md5 #2 & md5 #3 matched. Upon rebooting, I can't use su from the terminal (permission denied). I also tried "cd /sdcard && ./su" and got the same thing. Does this mean the rooting didn't work? Or can I proceed with wiping the device regardless? After I wipe the device I won't be able to perform the rooting steps again...and will likely have a brick...just totally paranoid here.

I followed that one as well. And I assume you rebooted after that point.
Did you continue forth and factory-reset/wipe and then install CM7 over your stock install?
Basically the downgrading/etc makes the phone exploitable, and then the rooting portion puts you back up to a engineering hboot and such that is unlocked with S-OFF, from there you either flash a pre-rooted ROM (i.e.: CM7 etc), or you root an existing stock (which would have gotten wiped from the hboot replacement).
If you already flashed CM and can't do su via adb then it's possible that under "Security" or "Development" in your phones system memory that su is restricted to "app only" and you may need to change that to "app and adb".
You shouldn't be running su from /sdcard (since that's not a linux style partition, and /sdcard is a no exec area). The su binary should already be installed to system in CM.
Clarification If you did not yet reboot (i.e.: Step #7 and onward), and then wipe/flash cyanogenmod (or another pre-rooted custom rom), then proceed with the steps, otherwise you're just working with a half-processed phone and naturally nothing would work in that state.

You mean hold "down" and boot into recovery, and immediately do these steps? No, I did not. I let the phone boot as normal, to try to run su to verify if the rooting process worked or not.
I suppose my question should be: how can I verify that the rooting process worked, and I'm ready to wipe? The su on /sdcard was pushed there by adb and used during the procedure. From the guide:
adb push su /sdcard/
adb push Superuser.apk /sdcard/

Don't use Visionary unless for some strange reason your phone came with Froyo (2.2) on it (it's an outdated method, and has a high brick rate). Given that you may have an asian rom etc, I would just go ahead and do a factory reset /wipe via recovery, and flash CM7 or a pre-rooted stock rom found here on the XDA forum for the best result.
I think even one of the AOKP or Adromudus comes with Pinyin input support already if you need it.
It did have Froyo. I have uninstalled visionary per instructions before performing all these steps. But since I only get one shot at rooting correctly, I want to make absolutely positively sure the process worked before I do something irrevocable like wiping the entire phone, only to discover I can't install a new rom because the phone isn't rooted.
I use third-party programs (GO keyboard) for all of my Chinese needs, and they've worked fine so far.

Rooting is at the rom/kernel level. But in order to flash a new custom kernel would need an unlocked bootloader which you already did with S-OFF.
So you would either flash a pre rooted rom like almost everything available via the developer section here (via recovery not hboot) or a stock rom then root that.
If you do everything via recovery you are less likely to accidentally lock/unroot the phone since recovery normally deals with the rom/kernel /cache and not hboot.

It worked - thanks! I was so concerned about bricking the thing. The whole process was easy...now that I've done it. Cyanogen came up in Chinese...couldn't figure out how to change it to English for a while. I suppose there's some setting in my phone that tells it to default to Chinese. It also appears to be locking up frequently on my phone - but at least I got the software on there, and now I can play with other mods. Thanks again!

If I had to make a guess, I would probably say you flashed Cyanogenmod onto the phone WITHOUT first doing a factory-reset/wipe, in which case you probably broke it (hence the language and freezing) by merging cyanogenmod on top of the pre-existing rom.
No, I definitely wiped the phone first. I got a few lockups in cyanogen so I went to install another rom. Now I'm getting "E:error in /cache/recovery/log" and "E:can't open /cache/recovery/log". When I install a new rom, it won't take and boots into cyanogen. It was in a reboot loop for a while but now it has booted into cyanogen again. Sigh. This is what I was afraid of.
Boot into boot and write down everything on that screen (power+volume down) just to check all is well, what is your recovery?
Search out two things (just use search function in g2 xda threads)
1 superwipe+ext4.zip
2 elitemod cm7
Boot into recovery and flash the super wipe like you did the from
Now flash elitemod
Is all well at this point?

Actually the phone seems to be working with cyanogen now. I suspect the internal memory is corrupt somehow, and that's a problem that can't be fixed. I'm going to stop messing with it before I brick it. If any more problems I'll revive the thread. Thanks so much to everyone who helped. I really can't afford a new phone right now and cyanogen seems to have fixed the problems I was having with the stock rom.

If the emmc is faulty then it's going to eventually brick itself, and should probably be sent in for warranty if available.
Model: Samsung Galaxy S3 AT&T i747
Hi!
I was forced to encrypt my galaxy s3 in order to receive corporate emails on my phone using the stock email app. However I never imagined that encrypting the phone would literally lock the memory and options to customize the phone.
I tried to root the phone to benefit from more flexibility and also debloat the phone. However during the rooting process, I could not mount /emmc/ when using ClockWorkRecovery in the startup menu. Based on what I found on the web, I figured it was due to the encryption.
I then tried to factory reset the phone to get rid of the encryption but I simply can't hard reset the phone from the OS or the startup menu. When doing the reset from the startup menu, the errors are "Can't mount /sdcard/". The reset continues but when the phone reboots, all my applications and personal data are there and the phone is still encrypted.
I read a lot about flashing a custom recovery via flashboot or ADB but I am reluctant to do it without guidance from the experts (you guys).
I deleted my corporate email account (It is my personal phone, I am not required to install exchange on it).
I tried to use an external sd card but as soon as the phone recoginizes it, I have to encrypt the card as well as a result from the corporate policies. I ejected the card and did not encrypt it.
I am new to android (long time iPhone user) and I would really appreciate your guidance on the methods to factory reset my phone or a different technique to get rid of the encryption because I am really stuck right now.
I have never encrypted an Android phone before. But maybe your response to these questions will serve as a "bump" to this thread.
1) What method did you use to encrypt the phone? Stock or 3rd party encryption?
2) Doesn't that same method also offer you the offer to unencrypt the phone?
3) If you used a stock method of encrypting the phone, then I'd assume your provider (AT&T?) tech support should be able to help you unencrypt it.
Eddie,
Thanks for your response.
1) I used stock method for encryption
2) Decrypt the phone is not possible apparently,only way is to factory restore the phone apparently
3) I went to the AT&T store and they were unable to factory restore (using the standard methods). They offered an exchange but since I purchase over the phone at a discounted price, I have to do the exchange using that method. Before shipping back the phone, I was wondering if I could fix it myself with the help of knowledgeable people.

I have never encrypted an Android phone before. But maybe your response to these questions will serve as a "bump" to this thread.
1) What method did you use to encrypt the phone? Stock or 3rd party encryption?
2) Doesn't that same method also offer you the offer to unencrypt the phone?
3) If you used a stock method of encrypting the phone, then I'd assume your provider (AT&T?) tech support should be able to help you unencrypt it.

I have never used the encryption but if the phone can turn on and is usable, cant you go into the encryption settings and turn encryption off? then you should be able to do anything (may be best to start with a factory restore first just so you have a fresh slate to work with)

Model: Samsung Galaxy S3 AT&T i747
Hi!
I was forced to encrypt my galaxy s3 in order to receive corporate emails on my phone using the stock email app. However I never imagined that encrypting the phone would literally lock the memory and options to customize the phone.
I tried to root the phone to benefit from more flexibility and also debloat the phone. However during the rooting process, I could not mount /emmc/ when using ClockWorkRecovery in the startup menu. Based on what I found on the web, I figured it was due to the encryption.
I then tried to factory reset the phone to get rid of the encryption but I simply can't hard reset the phone from the OS or the startup menu. When doing the reset from the startup menu, the errors are "Can't mount /sdcard/". The reset continues but when the phone reboots, all my applications and personal data are there and the phone is still encrypted.
I read a lot about flashing a custom recovery via flashboot or ADB but I am reluctant to do it without guidance from the experts (you guys).
I deleted my corporate email account (It is my personal phone, I am not required to install exchange on it).
I tried to use an external sd card but as soon as the phone recoginizes it, I have to encrypt the card as well as a result from the corporate policies. I ejected the card and did not encrypt it.
I am new to android (long time iPhone user) and I would really appreciate your guidance on the methods to factory reset my phone or a different technique to get rid of the encryption because I am really stuck right now.

1ofaKind,
Had EXACTLY the same thing happen to me. Encrypted my S3 in order to access work exchange server. Tried CWM but cannot mount /emmc/ problem after booting into recovery. Have not tried to factory reset yet as I am wanting to learn more before I go that route. But basically I am in the same boat as you. The only difference is I was not required to encrypt an external SD card when I put it in my phone. Read about flashboot as well...maybe the only way to actually factory reset after encryption??
Sorry I cannot offer any solutions at the moment...but I will keep scouring the forums looking for a way.
If I learn something valuable, I will try to post it here to help ya out.
EDIT: Maybe you have read these threads, but there is some decent info in them. http://forum.xda-developers.com/showthread.php?t=1451655 & http://forum.xda-developers.com/showthread.php?t=1392037

Look into using Odin to restore a factory image.
Sent from my SAMSUNG-SGH-I747 using xda premium
I'm in the same boat here - had to encrypt my GS3 in order to receive corporate (Exchange Server) emails. Now can't update the OS on the phone which is more important to me than receiving corporate emails on the device.
Can someone tell me how to decrypt (UN-encrypt) the phone? Everything I've read says that a factory reset won't do it.
Please help!

Has anyone tried this? If so, did it work?
I clicked install rom from sd card in cwm selected f/w which i had copied into internal memory. Did factory reset in recovery.
Odin it back to stock.
This might be too late to help you guys, but here's what worked for me. I odined it back to stock. Then I went into recovery (volume down, power and home button) and selected wipe data/factory reset. This does of course erase all your data, so try to copy whatever you can onto a computer or something before doing this. You should end up with an unencrypted storage.

After you hit start, unplug then replug the usb from the computer. I had some issues with it not recognizing it either to flash stock, but when i messed with the cord, it made the noise that i unplugged and it started working. Same thing with the root injected, only this time i fully unplugged it when the fiddling with it didnt work. Make sure you replace it into the same com port.
so, i seem to be having the same problem as all of you, only i encrypted to protect my data from agents. So, right now, i am *hopefully* :fingers-crossed: installing the root injected JB now. I had many issues. TWRP and CWM were no help, couldnt see phone to add new roms to it. ODIN was the only hope. I booted into recovery after going back to stock, did a new factory reset and am installing the stock with root. When i let it boot, it didnt go to encryption this time, but the first time i flashed the stock, it did. This is a mess to say the least.
EDIT: YEAH! done. No encryption and i got root. i used the image from here: http://forum.xda-developers.com/showthread.php?t=1968625 DLK3 worked for me. Good luck. i hope this helps. Ill be happy to explain more if you want.

ODIN (for me at least) wont see anything since im using Windows 8. On Windows 7, however, it works just fine.
Factory reset encrypted phone
hi,
I'm using CM11 as a rom.
I didn't want to reinstall stock rom, just to root it again later.
Installing updated version from external SD didn't work (updated the ROM but no decryption)
Tried to factory reset from recovery - didn't work, as the internal storage is encrypted it can't mount /sdcard/
however, from within settings menu, in backup&restore there's an option to do a factory reset - this is formatting internal memory altogether.
worked like a charm.

I understand this is very old but I am going to make a note here in case anyone else gets into this problem. When you go back to stock, do the factory reset using the STOCK recovery. Don't install TWRP or anything else until you have cleared the encryption. At least, that's what worked for me.
Ive been on ICS/JB for a while, but my battery started to swell and i need to flash back the stock rogers rom.
Ive download from samfirware the only rogers rom.
I put it in the PDA slot of Odin3 and everything works.
When the phone reboots i get an error: Can't access /system/csc/att
And the phone reboots to the samsung logo and nothing more.
I tried using the famous oneclick we had for the leak ICS and this one works good. Only the 2.3 from rogers that fails.
Nevermind, the dude at rogers told me that batteries are not covered by the warranty.
It would still be nice to find the answer to the flashing problem.

Install CWM, format /system ... should take care of it .... (edit!! do this step BEFORE you flash your rom again and AFTER you complete a backup.)
Did you flash the original rogers from samfirmware w/ Odin ?

Can you help - think we have same kinda phones !
Hello,
I have Samsung Captivate Glide but USA Att version and recently ran into a problem - the phone froze and when I tried to reboot all I can see is Samsung Logo and then it just won't do anything else
I'm not very Skilled at fixing Android and it seems like a headache to me, but Im trying to see if I can fix my phone:
what I've tried so far is play with the buttons while trying to reboot a phone and it gives me that menu where I can clear cache and then factory reset, I've tried both and it still does the same thing. The last thing I am trying to do now is to use "Apply update from SD Card" option in the menu recovery mode menu - kinda last chance in my limited knowledge: I have downloaded original packages from Samfirmware website, but somehow it doesn't recognize them when I'm trying to navigate folders in that menu - Im not even sure what to call the files (what extensions ?) or that it is something that it will let me do from external sd card that Im using because when I open the external sd folder it shows nothing but the SD card is plugged in - I'm just trying to see if it would completely reinstall the whole Android 2.3 system this way.
I'm only contacting you because I can see your phone in the forum is kinda like mine but a canadian version and you seem to know much more about androids - I wish I knew more and could somehow reinstall the whole Android 2.3 from scratch - I do not use a Windows laptop but can possibly find it ( I use Linux Ubuntu) if their some kinda PC Suite Software that does this (no cds came with phone though). Also, I have never messed with custom ROMs or anything like that - last time I used it I watched video online and it froze. Do I have any options here ?? The phone is not under any warranty and I do not care about my files on it much - I just want it to work same as before because to me it seems like it's not a hardware issue but I'm not really sure. Although my phone is ATT, it is unlocked to Walmart Straight Talk Unlimited Simcard - which is very affordable to me as well, and I like this phone! I never upgraded to ICS from 2.3 because it ran smoothly all the time - had it for about 6 months - wondering what could be wrong with it, I already spent 3-4 hours on it with no positive outcome.
Can you help ? THANKS IN ADVANCE - ANY TIPS ARE APPRECIATED
Thank You
Vlad
Sounds like a bootloop, it seems you still have access to recovery mode so you might be able to reinstall your stock firmware from here
Sent from my SGH-I927 using xda app-developers app
I recently noticed a cluster of dead pixels in my screen and need to exchange it for a new device. To do this, I presumably need to unroot and revert to S-ON, even though this is purely a hardware problem. However I don't know where to start honestly, as this is my first phone I've ever rooted and am still learning (somewhat slowly). I made a backup of my stock rom, but I think I may have made it too far into the process, as the rom is already has supersu and cannot OTA update. I can't seem to track down a RUU, which is what I think I'm needing, but I'm not sure if those are released for this device yet.. I think I understand the process if I can simply track down a RUU or figure out what to do next. I'm sorry if this seems like an ignorant question, but honestly I"ve tried figuring this out for myself and I'm just needing a little help I think. Thanks in advance.

Who said you had to revert to S-ON again? Before doing things like that rather read this thread first
SuperSU won't prevent the device from doing an OTA update, did you get the notification for it and tried to install it directly after downloading it? If you have a custom recovery then the OTA won't install, supersu on the other hand won't prevent it like I said. I did the OTA myself while having SuperSU :good:
You can just uninstall SuperSU from the application drawer, open the app and try to uninstall it. If it doesn't work then perhaps try point 6 in this thread "unsupersu". Though you need a custom recovery to do this.

if I can simply uninstall super su then that shouldn't be hard to figure out. thanks. do you have any tips on how to remove the custom recovery? I'm pretty lost on that.

Download stock recovery from this thread just select the correct recovery that matches your software version.
Unzip the recovery and move it to the adb folder where you have fastboot.exe in(By default this is platform-tools). Hold shift then right click in the folder, select open command prompt/window here.
1) Connect device to computer
2) Type: adb devices to check if device is being picked up, should show you your serial number
3) Type: adb reboot bootloader
4) Type: fastboot flash recovery name_of_recovery.img
5) Type: fastboot reboot
6) Done.

Just for clarification, are flashing my stock rom backup and removing the custom recovery along with SuperSU all I need to do for it to be in a returnable condition? I really appreciate the help.:good:

Well your bootloader screen will still show "Tampered" and "Unlocked" (IF you haven't fixed these yet) so you might want to reset those flags as well before doing the unroot.
Remove Tampered banner
Reset lock status flag
Just follow those 2 guides made by Scotty. If you don't have the flags anymore and you have stock recovery in place, you can just uninstall SuperSU and you're good to go.
