[Q] How do I unroot the Arc S

So I rooted the phone a few weeks ago using the zergRush method. However, my phone has developed a physical fault and want to send it off for warranty repair (the screen on the lower left side feels loose and creaks when I press on it.)
So obviously I would not be able to send it off in a rooted state, so how do I unroot it and erase all traces of a root from the phone?

You can use flashtool to unroot I believe (though I've not done that myself)..
or.. you can simply repair the f/w using SEUS. that will remove the root..

What's SEUS? Is that PC Companion? Will that fully unroot the phone.

You could flash with Flashtool, don't matter if your BL is locked or unlocked.
Or you could use repair function in PCC/SEUS and the root is also gone.
Or if you have rooted your FW with DooMLoRD's zergRush exploit, look in the thread, for the unroot script.

Hmm, which is the easiest/safest?

SEUS is the Sony Ericsson Update Service - HERE
Use it to repair your phone - will complete remove all traces of root.. and is dead simple to use.. even for a noob!

There was no repair option, however there was an update + restore option, and it does seem like my phone is completely back to its original state. However, how do I confirm that it is actually unrooted?

Try running an app that needs root. You won't get the pop up asking for root permission, and the app won't work fully.

Open Terminal Emulator, type in 'su' and hit <RETURN>. You should get a message that the app has been granted root access. Or not.

Thanks for the answer, but not correct
The real problem was the unlocked bootloader, I had to re-lock it.

@mchaals You're wrong. Flashtool method works for both unlocked and locked bootloaders.

That's right, but it not solves my problem.
I have flashed couple of stock roms and kernels with FlashTool, even with official Sony flashtool, but I can't use SEUS to revert to factory state.
If you want to do that (for warranty issues in my case) you have to upgrade via SEUS or PPC - which is not possible because of the error caused by the unlocked bootloader.
Sorry if I was not clear
BTW I used this method to relock the bootloader:

[Q] Backing up stock firmware with locked bootloader

I was wondering how to back up my stock .42 firmware before I upgrade to .62 OTA. (With a locked bootloader)
I want to do this because .62 isn't rootable so with a backup I would be able to go back to .42 easily if needed and also it's nice to have a backup should anything go wrong.
Thanks

U need:
1. Root ur phone using doomlord zergrush if u havent
2. Download se xtreme tweaker on ur pc, run it and install CWM using the software
3. Now u have CWM, u can bckup ur .42. To do that, reboot ur phone n when the sony logo appear, press down volume key repeatedly until u enter CWM
4. Look for backup or something like that, i dont really remember.
Notes:
1.make sure u have all the drivers installed in ur pc, if not u might meet some problems installing CWM. To make sure u have the driver, u can find it in driver folder in flashtool folder. If u dont have flashtool, just search for gordon gate, that ought to do it
2. Make sure u hve 700mb+ free space in sdcard for backup

Thanks a lot, I'll try this tomorrow.
What do you mean by all the drivers? I've already rooted with zergrush and that was successful and I've got PC companion and SEUS installed. Do any other drivers need to be installed?

CWM auto installer
Hello,
u might wanna try this...saves time and reliable...
There is a Application in the Play Store(Android Market) named Xperia CWM Auto-Installer..by pvyParts
Link :https://play.google.com/store/apps/details?id=com.pvy.CWMinstaler
Once rooted, u can download that directly...Install CWM on your rooted device..
This App is designed for the 2011 Xperia porfolio. it will install CWM into the system partition so you can use recovery even with a locked boot loader!
Then re boot into recovery and go to BACKUPS AND RESTORE and do a NANDROID BACK UP...
Simple Isn't it?

Is this the same as the se xtreme tweaker method above?

Same on my LT15i - seems there's something missing. Both versions of the APK give the same result, it just doesn't work.

i had no issues
i had no issues on using this app after running the programme i had a back up and restore file in my xps that was not their before told me to run the root file did it all works perfect i used the normal mode in the run me file from bin4ry... option 1 i think..... even for a locked bootloader it worked as after doing my own xps that has unlocked bootloader i did same steps on my gfs xps and she has a locked/b/l worked first time no worries

on the Xperia S I had no issues as well - but the S has backup&restore on board. The Xperia arc doesn't have a backup&restore app in the ICS upgrade - and apparently there's a reason why (copying the respective apk from the LT26 doesn't work either)

I've tried both the apk's from this thread on my Sony Tablet S running ICS and both give the " Unfortunately Backup and Restore has stopped working" message. Any help much appreciated.

Install the latest FlashTool from here ( 0.9.5.0 ) http://www.xdafileserver.nl/index.php?dir=Sony+(Ericsson)/SE+Xperia+S+(LT26i)/TOOLS/Flashtool
In flashtool go to Tools -> Root -> Force Emulator
Then install SuperSU and busybox again if you dont have them

@conalt- Thanks for your help. I'm trying to install backup and install so that I can root the tablet. Does your advice assume its already rooted. Apologies if dumb question!

I even did the factory update to ICS and then tried the root methods.. no root.

Anyone have ANY luck rooting their AT&T Xperia Ion LT28at..?
Is there a program that can be installed on the phone (like Z4root or SuperOneClick) . I know those don't work lol.

I tried that. How can I downgrade back to gingerbread?
I did the ota 6.1 ics update. Then tried rooting.
Btw.. this phone has locked boot loader.

Get flashtool.
Turn USB debugging on in your phone menu.
Turn OFF MTP just change it to MTC or whatever the second option is, in your phone menu.
Plug your phone into your pc.
Open flashtool.
Look for the lock icon at the top left of flashtool, it is a big pad lock.
Click it- flashtools message box now tells you to open the backup restore app.
Go to your apps and open backup and restore.
Click restore.
Flashtool will tell you it worked and it is rebooting.
The phone will say failed plug in external memory. THIS IS SUPPOSE TO HAPPEN DONT TOUCH ANYTHING DONT UNPLUG ANYTHING DO NOTHING.
Phone reboots once.
Flashtool finds your phone and reboots the phone again.
Once your phone is loaded go to your apps and find supersu.
Congrats you can read and follow simple procedures!
Do I need to make a new topic with a guide for this? A few people are having issues with it not sure why it's not too hard lol

[Q] Basic quuestion about Xperia M dual (C2004) rooting

Hello,
I'm trying to figure out this but after so many searches on internet and XDA forum still not sure:
I want to root my Xperia M but wont touch the bootloader, ideally.
This rooting method dont change the bootloader?: http://forum.xda-developers.com/showthread.php?t=2529561&page=5
My plan is rooting, than backup TA partition (untouched). So that's why Im asking about the method described in the link.
Considering that this rooting method will not touch bootloader, after rooting, all changes will be performed/changed on the ROM? If yes I can just backup ROM and tag it as "rooted ROM", use it to restore to my phone when wanted?
I'm really confused about HW/FS topology. What are the parts? Hardware->bootloader->ROM ? Where resides the Kernel? Own ROM contains the Kernel?
I want to backup stock ROM before going to root. I know a method is using SUS to repair phone, extract downloaded files and compile the .tft. I'm afraid because in the past (on xperia mini pro), I did "repair phone" on SUS but it upgraded ROM to a recent version instead! It's probably I did something wrong? I wont upgrade latest but just backup actual ROM. There's any other method to extract ROM without using SUS and before rooting? (i.e. using CWM)
I know this is a lot of questions. Any help on any question, even individually is greatly appreciated.
Salute!

You can root without touching the bootloader with a small app named "Framaroot".Just give it try and select GANDALF Exploiter while rooting it.Google it for framaroot link

Hi XDASenior,
Thanks for direction. I tried framaroot already and it didnt worked. From informations on XDA topic about Xperia M x Framaroot, I think it doesnt work for Xperia M dual (C2004)

Hello ansebovi,
Yeah I'm on 4.2.2.
I was reading a lot of XDA threads last days. Also your topics are very useful, thanks for them. My question wasn't about "how to root my phone", my questions were about specific details I (still) didn't find on forums. Of course it may be I didn't search enough yet for those specific questions.
I don't care about having always the latest firmware and since I decided the root method for 4.2.2 (explained here at XDA), looks secure enough, I will just stick to 4.2.2 until I decide to upgrade in some future.
So, to root my Xperia M Dual (C2004) I followed http://forum.xda-developers.com/showthread.php?t=2529561
To have bootloader unlocked I followed a thread posted by you, thanks for that.
Finally I installed CWM for my firmware version using http://forum.xda-developers.com/showthread.php?t=2494793
It was hard to find how to boot into CWM but its simple as pressing volume up and power up buttons together when the purple light appears.
Now I have this issue: Telling CWM to make a backup, it does it copying files to internal storage and no to the SD card! So I ended for now with this last barrier to finally reach a production state and start customizing my phone. Any clue in this regard is welcome. I read somewhere that Xperia M have different (non usual), designations for storage points. Like calling SD as internal storage and stuff, but Im not sure if I uderstaood that well.
Anyway, thanks guys for the help and tips.
Salute

Just some updates:
Accordingly SUS terms of service you are able to recover your phone using SUS just if there's not any available firmware update. If there's some updated firmware, SUS will always flash your phone to that last firmware (even using option "fix my phone"). It makes sense by Sony point of view: They can save money on support if most of the people are updated and using a same firmware at a give time/period. So the method using SUS to backup your firmware is only effective if there's not any update available.
CWM x Xperia M works just great. Was me doing stupid things and selecting wrong mount point to perform the backup. Not sure if it's always the same but at least in here CWM calls internal storage as "/sdcard" and SD card as "/sdcard1". I read /sdcard and thought it were the right location... but it's not.
