Where does one find the kernel for .587? - Xperia Arc Q&A, Help & Troubleshooting

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.

Is SEUS is the same as Sony PC Companion?

No.
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
Its clearly explained how to do it, as Someguyfromhell said.
EDIT: The guide is for Xperia Pro, but same steps except its better if you have full tft of Your cell

flashtool 4.0.2.A.0.62 root

Can the new flashtools root 4.0.2.A.0.62 for arcs with locked bootloaders? Already upgraded once to find out i couldn't root it. Has anyone done this successfully with a locked bootloader as I don;t fancy experimenting again.
yes mate flash the old kernel from the .58 or .42 or .283 FW by excluding baseband & system in flashtool b4 flashing after that root as normal with zergRush..

Thats what i did last time i experimented and it didnt work. i installed 62 then flashed the 42 kernel with flashtool. But zerg wouldnt root it. But i flashed the kernel only. in one of the 62 threads there were links to getting it rooted with locked bootloaders. This went to a guide with nothing about locked bootloaders in it, only unlocked.
somewhere here in the forums is a thread about CWM for locked bootloaders, with that you CANNOT flash custom kernels, but old kernels in zip format, hang on i'll get you the zip + the link for the locked BL CWM.
http://forum.xda-developers.com/showthread.php?t=1390771 this is the link for CWM: follow these instructions for the arc : 1.Run install-cwm?.cmd
install-cwm1.cmd for Xperia Arc / Neo / PLAY
2.Enable USB Debugging on device
3.Connect your device using usb data cable
4.Follow on screen instruction
and here's the kernel it's the .283 kernel
it wasn't custom, it was the stock kernel from .42 flashed to .62 and zerg refused to root it. Although apparently this worked on previous versions as i tried flashing the .42 kernel over onto .62 as a tip from one of the other members on here. but I couldn't get it rooted in the end and gave up and went back to .58.
flash that kernel via CWM
so if done with cwm mod it should work then? Whats the difference flashing the kernel with cwm as opposed to flashtool? Would have thought it be the same.
dont know the difference, but this one worked for me
cheers ill give it a go.
no problem feel free to contact me via PM if you still have problems

I have the exact same problem as you. Did you manage to accomplish anything? If yes would it be easy for you to explain to me the exact steps? If not is it possible to give me the address or send me the .58 firmware for arcs (the ftf file). I wasn't able to find it somewhere. Thanks!
upgraded to .62 then tried to install cwm but it wouldn't let me as the phone needs root permission to be able to install it. So how did you deal with this? I also flashed the .283 kernel with flash tools after updating to .62 and zerg again failed to root the device.

Ok, I'll give it a try.
Before I go back to .58, is there any rumour if Flashtool is going to support rooting on .62 firmware soon?

Nope... the zergRush exploit has been patched on .62 fw and there wont be another exploit on Gingerbread, since we're going to ICS.
is there anyway to root 62 without unlocking our bootloaders or is it nay to impossible?
So far I wasn't able to find a way, so I think I'll just go back to .58 or .42 and root, waiting for the official ICS.

[Q] How to back up app data & settings without root and Ultimate Backup Tool?

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

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.

Update Arc S to latest ICS stock ROM

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.

No you cant flash kernels whrn your bootloader is locked...
You must unlock & root your mobile 1st.
You can only flash firmware(ftf) files with above configuration...

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..

use flashtool and inside of flashtool the tool "Xperifirm".
With that tool you can download latest firmwares .ftf
Flash downloaded firmware with flashtool.
And important: to receive Sony updates you have to relock your bootloader: http://forum.xda-developers.com/showthread.php?t=2642081
Cause unlocking bootloader "kills" the FOTA partition (for me this partition is very useful cause i flashed a permanent TWRP recovery inside it), but you need this partition for Sony updates via Sony Companion etc....
BUT: this method only works if you unlocked the bootloader the official way via Sony homepage
