Hi, everyone. I can't seem to find the solution for my prob, so I've to ask for ur knowledge on this.
Problem:
I'm using Xperia Arc with latest stock firmware without root. And I want to back up my app data & settings before resetting or flashing it.
Attempt:
I've tried Ultimate Backup Tool, but to no avail, just as mentioned in the Ultimate Backup Tool thread that there are known problem with Xperia Arc as one of the Sony 2011 devices.
I've looked through all the rooting methods for Xperia Arc, and I can't seem to find or perform a working root on the phone without flashing it. Naturally, Titanium Backup can't work as well.
Question:
So, what options do I have to back up the app data & settings now? And I'm looking that whether will a flash necessarily wipe the data on ur phone? Can I retain the data even after flashing the phone?
Really appreciate for ur help. Thx~ =)

You can't, it's not possible to access and backup app data while your phone is not rooted. Are you on GB or ICS?
BTW, you don't have to flash your phone to root unless you have to downgrade. In the instance for ICS .587, I only need to flash the kernel of .562, root it via adb, then flash back the .587 kernel. This should not wipe your data.

Thx a lot for ur reply. I'm on ICS .587 too. I was just afraid that flashing would wipe the data. And now this is clear.
Seems like this is the only option that I have, right? Btw, won't flashing it back to the latest firmware lose the root? Bcuz I used to have root, but I lost it when I updated my phone through official update methods. Or is that why I lost root?

You lose root from both flashing stock firmware and updating through official updating methods.... at least for locked boot loaders

Yes, flashing will lose your root, so does updating it via the official method. Flashing the entire ROM would wipe the data, but flashing the kernel does not.

Really? Then, what's the point of downgrade the firmware then upgrade again? Lol~
So, does that mean that with unlocked bootloader, I can keep root even after upgraded?

You can't root the latest firmware so you have to downgrade to root. You then upgrade by flashing the latest firmware's kernel which upgrades the firmware to the latest version and also keeps root status.
As for unlocked bootloaders, I can't comment because I have no experience with them

I think I got u wrongly before this. Lol. Bcuz you said that flashing it to the latest firmware will lose root. Or do you mean just stock firmware?
While for unlocked bootloader, can popthosegaskets or anyone else share the insight? Thx.
yep i meant flashing any stock ftf will make you lose root on locked bootloader

So that means that if I want to upgrade to a later firmware without losing root, I've to use a custom firmware?

Nope. You flash the kernel of the latest version of stock firmware. Here's an example

ごめん~ごめん~
Sorry for the late reply
Anyways, I tried flashing the .587 kernel on my .562 stock. My firmware version still read .562, so I don't think flashing kernel will update firmware on unlocked bootloader.
As for rooting the latest firmware, you can update first, downgrade the kernel and root. You can keep data this way and get root.

Yeah, when you unlock bootloader, you also remove DRM keys that connect to Sony servers. So Track ID, Playnow and other Sony services won't work anymore. You also cannot use OTA updates as it will brick your phone.

Hmm~ I'm aware of that. But from first impression, it seems like they're not that important, since apps like Playnow are not useful. The only one that I use is TrackID, which I saw Sony published it on Play Store for public download. Sounds like it's fine to lose the DRM key too. Lol.
Arc S kernel and Arc kernel is different. Don't flash or it may cause problems.

Is there a way to update to the latest version 4 with unlocked bootloader? I dont really care if I loose the root or not. The last time I tried to switch to stock from my rooted .145 and update from the phone, my phone "brick" on me. Luckily there is a way to fix the problem.

No, I haven't. I have locked bootloader(yet). But read about it in some threads. Is this just an offer from me... Read the comments.
Ok finally after several research and try I find the following are the easiest method of getting root on the latest version (for people with unlock bootloader).
1. Flash using Flashtool any unrooted version 4 ROM
I used the following: http://forum.xda-developers.com/showthread.php?t=1209237
2. Switch off your phone, and boot into fastboot mode. How? When the phone is off, hold the menu button and connect the USB cable to the PC.
3. Using fastboot command, flash the boot image created by Doomlord. Here is the link: http://forum.xda-developers.com/showthread.php?t=1172885
4. Boot your phone, and enjoy the rooted ARC
Yes kuailan thats the same method I used. Its not just a rooted arc now, with setcpu app you can under/overclock it, and i dunno if any other addons.
Anyway, remind yourself and everyone that once its in that state, never do OTA update as doing that on a bootloader unlocked phone will result in bricked phone. Its recoverable, but requires additional effort. So there's the warning.
Unfortunately, I forgot that I lose root when I update using SEUS & I updated to 4.1.0.B.587 & lost root. I've heard that root will still work with the newest version, but I need the .587 kernel. Where can I download the kernel itself?
Thanks.

OP: Just use regular .587 .FTF file and install only the kernel. Exclude everything else. And untick the Wipe options.
You can follow this guide

Hi guys..
Am in need of a little help here. I need to root a Xperia S running 2.3.7 (Yes, oldie) with firmware version 6.0.A.3.62. This is kind of an official purpose, so i have to be in 2.3.7. Aslo updating the firmware version is my last choice. When i searched, i couldnt find any pre rooted images for 6.0.A.3.62 firmware. Can somebody help me with a pre rooted image or any other method? I want it to be in the generic customization..
If in casei want to flash a pre rooted image of a newer firmware version like 6.0.A.3.73, can i directly flash the image via fastboot? or should i take some precaution since am upgrading from .62??
Your help is much appreciated..
You won't get much answer here as you have posted in the wrong section. Post this in Q,A

have you tried bin4ry method?
if you wanted to flash pre rooted firmware I take it your bootloader is unlocked? If so its very easy to root any room through cwm.

Thank you all for the response.. I have a small query... the doom kernel has any difference (apart from root and recovery) compared to the stock kernel?? like any tweaks or something??? because i want the phone to be exactly in a factory condition.. Please don't think that i have too many demands... .. the device is used for a testing purpose.. that's y all these mandates...
I am ready to unlock the bootloader.. so in that case... like solders33 said above.. can i just flash CWM recovery via fastboot and then istall the super user .zip via CWM?? will it work in .62??

Like what DooMLoRD has mentioned in his kernel thread, his kernel is just the stock kernel that has some ramdisk changes and support for init.d and userinit scripts (besides root and CWM).
Thanks for the reply.. One more quick question... If i want to flash a pre rooted image of any newer firmwares.. say .67 or .73 .. can i just do that with fastboot flashing?? any problems in updating like that???

You should flash the pre-rooted image of your present .62 firmware, not newer ones.

Hi guys!
I have an Arc S (Lt18i) stuck on Gingerbread and I would like to have the latest stock ICS version, which I think is 4.0.4.
I understand I have to use a program called flashtool.
Will I be able to flash the ROM using flashtool if my phone isn't rooted and the bootloader is locked?
And could someone point me to a link to download the ROM?
Thank you very much.

Flashing via Flashtool will always wipe data. Unless you have a nandroid backup, it's not possible to keep apps and their data.

yes. (& personal data also, so make backup) but root is a easy job (1min) you can root phone with ''e-root'' app. btw if u plan to use custom rom , then no need to root it all custom rom/kernel is prerooted....
if not you can extract kernel & try flashing i manually..
