Oh yeah, haha my bad. I did see that after i posted D:
Btw, how did you unlock your bootloader? i've read up a bit on this and i haven't got clue. It'd be great if you could help
Thanks iceman

you can just go to the Sony Ericsson homepage or follow a tutorial on this page. It's really not hard to unlock, just remember, you will wipe your phone - so better make a backup first

hi, I just rooted my locked arc 15minutes ago using gingerbreak v1.2 and as far as I can tell so far it went well I'm not experiencing any problems.
My question might sound dumb but does rooting the phone also unlock it ? cause mine is still locked and I'd like to unlock it.
Is there another way to unlock it ?

Hi
As far as i know, safest way to unlock bootloader is from se site. U can only unlock bootloader once... U cant re-lock it after

if you use gingerbreak, then it is still locked. go here "http://unlockbootloader.sonyericsson.com/instructions" to safely unlock your phone. Just remember unlocking will void your warranty.

That's actually the first method I've tried but I but I couldn't manage to start the fast boot once I've turned off the phone; and I've followed the tutorial on YouTube exactly. The led just won't turn blue I've tried it several times.

If you're following the instructions properly and its not working, then that probably means your phone is branded and the bootloader can't be unlocked. There's a thread going on here about trying to enable fastboot on sim-locked phones: http://forum.xda-developers.com/showthread.php?t=1063394

I've found the code for 25€, witch I consider to be a good deal considering the 65€ I was originally asked for on my network so I'm gonna go with that. I've already ordered it.
I've read the thread you posted and It's still a work in progress, I appreciate the effort that's being done but 25€ is not much and it's risk free.

[Q] Easiest way to root a unlocked bootloader Arc running on 2.3.3 ?

If you have an Xperia Arc version 2.3.3 unlocked bootloader, you can't root using Gingerbreak or Super1click as the update, unwillingly, made sure that stuff doesn't work anymore.
The only way to root, as far as I know, is flashing -> getting 2.3.2 ROM -> root from their -> update.
I can not use that way as everytime I try to update in the last step it wont turn on again after reboot (so I have to flash using http://forum.xda-developers.com/showthread.php?t=1126358, though i'm sure it'll work for most of you.
Question being: Is there atm really no alternative to root for me then? I'm kinda desperate, i've been looking on XDA a lot of hours and this is rly my last hope to get this over with..
thx in advance!

As you said yourself.. You have an unlocked bootloader.. so you don't have to more like you cannot use the FOTA technique cos OTA update bricks the phone..
Simply flash one of the prerooted kernel like DoomLord Kernel.. Should do it .. Or if you want the stock kernel then Serach the forums for something like "Root 4.0.A.2.368" They will usually specifically say that you need unlocked bootloader..

[Guide] All in one 'Namaste guide' to Bootloader unlocking, Rooting, Flashing & more

thx for the replies.
though, I've read that whole guide before, problem is:
"Ques – Ok. So quickly tell me how to unlock my Xperia Arc’s bootloader and install a beautiful Custom ROM.
Not so fast dear. I described a deal about bootloader and benefits of its unlocking but let’s get practical. There are two disadvantages of unlocking the Xperia Arc’s bootloader.
As per my knowledge, till date, there is no Custom ROM designed for your Xperia Arc. So, it’s useless to unlock your bootloader. "
So, if a "non stock kernel" means the same as a "custom ROM", where do I find it? i dont want the original one as that1 is outdated. I know how to flash my phone, but only with delivered folders (which are always X10)
with kind regards,
Tom

I have the same problem with my Neo. I've tried flashing 2.2.2, then rooting with Flashtool (just click Xperia X10), but this doesn't work, and after relocking the bootloader and updating, the phone is bricked as well. Tried this like 5 times.
I think I'll just wait for 2.3.4 as my main reasons to root are making screenshots and removing bloatware. 2.3.4 adds screenshots, and currently, my ROM is not totally full.

Same here, just wanna get that bloatware off, starting to look like i'm gonna wait as well... this has already taken enough hours away from me

Hmm.. Only non stock kernels yet around are the DoomLord and CM (FreeXperia) kerenls.. Check the development forums for them..
The Stock aren't really "outdated".. These custom kerenels are based on the original stock code with a few features enabled.. So don't expect android 2.3.4 from them or anything..
As for rooting issues.. Follow the Namaste guide and a few posts in the development forum bout rooting arc properly and carefully.. Noting what is Locked and Unlocked and which method works where.. And it won't take more than 15 minutes to setup everything..

[Q] Rogers Branded Arc - Flashing CM7

Hi,
As it is written in the thread title, I am the proud (and frustrated) owner of a an Xperia Arc on Rogers (Canada). I am frustrated because since the "classic" bootloader unlocking methods do not work with Rogers branded phone, I'm unable to use any flashing method that require fastboot.
Also, I've seen a bootloader unlocking method that involves removing the battery, attaching wires on contacts, ... And I do admit that this kind of stuff scares me a little bit.
I wanted to know if wether or not it was possible to use Clockworkmod recovery (or Rom Manager) with a rooted 2.3.2 version and "just" install CM7 that way ? I know it sounds a little naive, but I'm currently stuck trying to root (after a downgrade to 2.3.2) with Gingerbreak and it stalls and the phone ends up never rebooting.
So if anyone has a solution/idea on how to flash CM7 on my locked bootloader Arc, that would make me (and probably dozens of other Rogers Arc owners) sooooo happy.
Also, I just wanted to know if it was possible to flash CM7 with Flashtool ? Before having my Arc, I had an X10 and used flashtool about 15 times to flash MiUI Roms... If yes, would it be by "converting" the CM7 files into a .ftf file ?
Thank you very much

if i were you i would save the hassle. unlock bootloader, and go. i just did it this past weekend so i can get root without jumping through hoops.. i was extremely anxious about it too..but if you follow the instructions you really cant go wrong. ps. im using rogers arc too! and as to your questions.. i really dont think you can.

As CM7 is getting stable and since its pretty much release, I was gonna start to work on this ...
I was hoping to unlock bootloader ( through either sony , or one fo the threads and peeps that can do it here ) , root it and enjoy CM7.
Hope the official one works :S

It doesn't, no Operator locked handset can, so you will need to use Alejandrissimo or Jinx13. Worth every penny.

Hi,
Thanks for your quick answer gk_terato. So is the 24 USD $ really worth it (e.g. with alejandrissimo) ? I know a fraction of this amount is used to pay the tokens, but I don't know how much this is really worth... I've (sim) unlocked all of my previous phones and it was never over 15 CAD $.
And btw, I was just wondering wether or not unlocking the bootloader would, at the same time, remove the sim restriction ?
Thanks again !

[Q] In need of guidance :)

Hello, and sorry for bugging everyone, but I have somewhat of a problem. I'll just start from the beggining.
First of all I own a SGS II, so I'm used to flashing roms and kernels custom stuff and all...on that. My girlfriend is the one who owns a Xperia Arc S (LT18a, US version if it's relevant or not). And for the live of me, I can't summon the courage to flash it, the process being somewhat different than the flashing of a S2. That's just idiot proof in my opinion, can't go wrong. I'm seeing all over the place guides and stuff for flashing a Xperia Arc S, and don't really know wich one is good/bad etc. So...the actual questions :
1. Where can I find the stock firmwares for Xperia Arc S ? I was hopping on a website something like sammobile for samsung, where I can find every release etc.
2. She now has 2.3.4 (I think not 100% sure) build 4.0.2.A.0.62 and from what I heard that cannot be rooted, or it involved something like unlocking the bootloader or something like that, safe to say that kinda freaked me out a bit.
3. I'm guessing that this build 62 is like on my samsung, where different stock rom's are differentiated by letters (eg. XXLPG, XWLPQ etc) so, someone please confirm that.
4. Is there any noticeable difference between these gingebread builds, cause if build 62 can't be rooted, I'll downgrade to previous build that can be more easily rooted.
5. I really need a idiot proof guide to flashing this thing. She has no warranty on it and I really don't want to mess it up
6. And last (finally, I know ) some links for safe versions of flashtool (equivalent of odin from what I understand) and firmwares, stuff I need to root it etc.
I apologise for such a long post but this stuff is pretty overwhelming for me. Also I apologise for spelling errors (english is not my first language)

Wow, the things we do for love...
OK, here's a quick run-down of how it works.
Firstly the bootloader thing: -
The bootloader is where the "kernel" sits. If you unlock the bootloader then you can pretty much put anything on the phone.
You can flash a custom kernel, and from there on you can use ClockworkMod recovery the same way you do on your Samsung.
(
custom kernels have ClockworkMod recovery built into them since the XPERIA doesn't have a "/recovery" partition for the standard ClockworkMod recovery.
If that didn't make sense then here's a translation "There's no special space for CWM recovery on Sony phones! So custom kernels have CWM recovery built in for easy access."
When one of these kernels starts up the phone there's a point where the hardware buttons light up, and the LED flashes purple. If you press "volume down" at this point then the kernel starts up ClockworkMod recovery instead of booting the phone.
Most roms come with their own kernel that you can use like this. The XPERIA is different to the SGS phone because you can't flash a kernel from the phone itself. You need an unlocked bootloader and fastboot to flash a kernel.
)
So unlocking the bootloader is a good idea, but only after you've made a backup of all your stuff off the memory card.
Here's a really good thread that brings together all sorts of pieces of information that you might need to root the phone - http://forum.xda-developers.com/showthread.php?t=1653188
OK, so that's the unlock thing, and the kernel thing. Once the kernel has CWM recovery built in you can pretty much flash any rom you feel like flashing. There are already some JellyBean roms out that are fast and usable if you're prepared to read up on them and experiment a bit.
Next thing is the "BaseBand". This is the driver for the "cell phone radio". The part of the hardware that's actually responsible for behaving like a phone
Here's a thread where you can get all of the different base-band versions: - http://forum.xda-developers.com/showthread.php?t=1688049
Personally I know that base-bands 72 and 77 both work perfectly. Since they are the 2 newest versions you can choose which-ever one you want. The newer basebands give much better signal strength on the phone, and the call quality is really good.
Good luck with the experimenting - hope you enjoy.

Not really, from what I hear ICS dumbs down the phone sort of speak. Now I really can't say, but I would test it out a bit, as long as I learn how to go back to GB.
Another thing that I'm a bit concerned is that all the stuff I find are for LT18i and my gf's phone is a american model LT18a. Will this be a problem ? Or that's just to differentiate the hardware stuff in them ? I hope flashing a LT18i firmware doesn't screw anything up

Click to expand...

Yep, the differentiating factor is the hardware. the lt18i and lt18a roms are the same as far as I know. ICS does tend to be more resource heavy especially on the arcs but downgrading back to GB is basically the same method as flashing the ICS, just with another rom.
And also, in response to your first post, you can downgrade to the rootable build of GB, root that, and then flash the build 62 kernel back onto your phone so it's rooted and of the desired build
There's a lot of flashing guides on youtube regarding the arc s. I did a quick search and this one seemed pretty accurate and straight to the point.

Ok I pretty much understood the whole shabang, my last question is about the bootloader, if I unlock it once that's it ? I can flash whatever I want and not need to reunclock it...sort of speak. I read that for warranty reasons it can be relocked but that's not the case for me. Also for flashing a stock rom is it necessary to unlock the bootloader or that's just for rooting ?
Oh and almost forgot...if I understood right...I can downgrade...root...then upgrade to 62 and it will still be rooted ? On my samsung if it'a rooted and I flash abother stock rom...bye bye root, so pretty weird for me. Thank you again, I can't stress enough how helpfull you guys were.

unlocking the bootloader allows a whole lot more things to be done with the arc, but does make some apps defunct such as track id and music facebook like (which many can do without). flashing and/or rooting a stock rom doesn't need an unlocked bootloader because it's stock and yep, you can downgrade/upgrade, root, and then go back to what build you want by flashing a kernel only

if you unlock the bootloader NEVER UPDATE OVER THE AIR this will brick the phone.
The're 2 ways to unlock bootloader
1 via Sony web site but this only works for non branded phones,
2 is to pay if you use a service with setools this will unlock bootloader and make phone SIM free.

Warning: Incoming Noob - AuroraPlay v1.1.0 Install

First and foremost, I apologize for being such a noob.
I don't know what I'm doing here, since this is a place for expert developers, and I am not one.
But, I'm purchasing an Xperia Play very soon, and I ran across the AuroraPlay ROM which apparently speeds up the device a bit (Main Features - Clocked by default to 1.2GHz, Full GPU Hardware Acceleration, Boots in less than five seconds, etc.)
So, I thought, "This is really something, I should think about installing this, it'll surely make games and such a lot more fun on my Xperia Play."
I know the mere basics that anyone knows- unlocking, rooting, roms, kernels, firmware, etc.
But when it comes to getting down and actually doing something more advanced than simply rooting or unlocking a phone, I get cold feet.
What I mean by this, is I'm not completely sure how to install this ROM, and I don't want to brick my phone.
I've seen the installation instructions, though I'm still confused on some parts.
What's an Un/Locked Bootloader? How do I know if mine is un/locked?
How do I "Flash using Flashtool"? or "Root using Flashtool"?
What is X-Parts Recovery? What is ClockWorkMod? How do I use them?
At this point it may seem obvious this isn't for me, but if there is a more detailed tutorial out there for this ROM, that would be EXCELLENT! :laugh:
Again, sorry for the trouble.

Un/locked bootloader is about changing kernel and u can find it with enter *#*#7378423#*#* in phone
And if u have unlocked bootloader u can flash a kernel using flashtool with going to fastboot mode(power off ur phone and hold search button then plug ur usb)
To root ur device using flashtool u should connect ur phone to computer then in flashtool click on opened lock
And x-part is an app that installing recovery for locked bootloader and with recovery u can install roms on ir phone

First and foremost don't think you're a noob, everyone has to begin somewhere.and I don't own an xperia play but the basics are all the same.A flashtool is a program used only to flash roms and kernels but not root your device. For rooting, there are other toolkits, most of them really simple, just plug ur phone and follow the instructions shown.as far as I know, there is no need to unlock the bootloader of ur phone as long as u flash stock based roms but to flash custom kernels and roms,u need to unlock the bootloader and the bootloader for any mobile will be LOCKED by default. Behold.. Unlocking the bootloader can only be done officially and u will forever lose warranty and some other stuff like drm keys,etc..relocking the bootloader is also possible but ur warranty still be void.clockworkmod(cwm) is a custom recovery which gives many more features than a stock recovery and is used for flashing firmwares, kernels,etc,u can see about that on YouTube cuz there are walkthroughs for almost anything.I don't know much about X-parts though.there u go.hope I helped u.hit thanks if I did.

Thanks for the replies.
By the way, is there anything I need to do with my phone before I began the installation process? The phone obviously needs to be rooted, right?
Or can it be done straight out of the box?

If u r gonna root the phone as soon as u open it,there is nothing much u need to do..download all the files beforehand and be sure to double check the model number of ur device.if u really want to flash a custom kernel,u must unlock ur bootloader and as it was said,u won't have the warranty after that.So what I suggest is u use the phone for about 2-4 days and make sure there is no defect in it,just to be sure.So happy rooting!Hit thanks if I helped.

To install jelly bean you need to unlock your bootloader. The touchpads are not working very well though...
About the warranty thing, Sony says this voids your warranty, but I did it anyway a few months after I got my phone, and recently both of my cameras died (not at the same time, but I didn't care about the front camera) and they fixed them for free so maybe they still fix hardware defects (they did it for me). Of course I did re lock my bootloader before giving them my phone but they could know it since they had mY IMEI
