UL bootloader, GB -> ICS? - Xperia Arc Q&A, Help & Troubleshooting

Hey guys, I have a question.
Right now I'm running stock Gingerbread on my Arc S, with unlocked bootloader ( I tried a lot of ROMS ) and of course root access
If I wanna upgrade to ICS, may I do it the " proper way " via Sony Companion? Or do I risk bricks and stuff? I know I can flash a .ftf but that way I'm gonna lose everything and I have to start all over, and I did that so many times switching roms that I'd really like to avoid it if I can
So, with unlocked bootloader and root access may I use the official upgrade from Sony or I'm gonna brick everything?
Thanks in advance

Sony companion doesn't work. You should use flashtool.

Relock bootloder and then flash gb rom with flashtool then try pc campanion

If you are rooted on GB and then try to update with PC companion the ICS will unstable... j tryed and many programs crashed.... so bacup your data with titanium backoup and flash ICS .ftf with flashtool that is the best way..
Hit thanks if this post usefull for you !!!!

thank you guys, that's what I thought, now it is confirmed

Going back to stock ROM

OK,
after having my Arc bricked and recovered, I had what I thought was a stock 4.0.A.2.368 ROM aboard, but when I connect to PC Companion it says that I have software that cannot be updated.
SEUS gets as far as connecting the phone in flash mode and then it says "checking connected phone" and then it hangs.
How can I get back to a stock ROM that will allow SEUS or PC Companion to do updates?
I am not interested in OTA updates.
I am passing the phone to someone who is not terribly technical and want for them to be able to do the updates via the PC at least.
Cheers,

Use the flashtool.

use the latest flashtool and latest stock ROM..!
latest flash tool here :- http://forum.xda-developers.com/showthread.php?t=1000012
Thanks guys,
but I thought that by using Flashtool to go back to a stock ROM, 4.0.2.A.0.386, that I'd be able to then use PCP or SEUS to go to the 4.0.2.A.0.42 ROM, but I could not.
SEUS just hangs and PCP says modified software that cannot be updated.
I have used Flashtool to go to the generic .42 ROM now, but what happens when the next official update comes out?
Thanks

lock your bootloader then update
Ah, OK, did not realise that the unlocked bootloader was the problem!
Thanks a million as they they say here!

Sorted! That worked, thanks to all!

[Q] [SOLVED] help I messed up and can't get in to CWM

I got my LT18i .42 Locked Bootloader. Rooted with zergrush, installed CWM using the Xperia CWM installer from the market, and all was perfect... Then updated my phone using companion %&@@&%. Then read that I can't root .62, so I downloaded a .42.ftf, flashed it booted it and noticed that now I had a LT15a at first thought it booted so should be ok I'll do a OTA update see what happens. Rooted, CWM installed. Reboot, reboot, press (any key) freezes at boot logo. Using Rom manager to reboot to recovery just reboots normally to android. For the past fiew days I was reading up on this, but could not find any definitive resolution. Tried reflasing proper LT18i .42, .58 using flash tools, and using wotan client. Tried repair with both companion and SE update service, then downgrade with flash tools and with wotan, obviously I don't mean all at once just different methods . Root seems ok titanium works I can get in and edit system/bin, /xbin. I tried manually moving the files for CWM, and changing permissions. All with no luck. Yesterday I came across a post that said that the LT15 room might have changed something to do with mounting the sd. But no explanation. I'm not a complete noob but need assistance on this.
Thanx guys.
Flash an Arc S firmware on your Arc S and you should be good to go.

try unlocking your bootloader, why not? unlockbootloader.sonyericsson.com/instructions
Thanx anthraxter
I have been thinking verry hard about that, but still on a contract, so dont want to mess with that. i have been plaing with fiew rooms on my X8 (unlocked Bootloader) before i got this ARC S, and not without snags, but allways managet to get it back up. Do you think it's the bootloaders fault??

I can't tell you for sure but I would suggest you to unlock it (75%) . Download this LT18i_4.0.1.A.0.266_CUSTOMIZED-UK -( mediafire.com/?ie832txe46ia2bh) Always worked for me to do a clean install if i was gonna flash-it, download ROM Manager again and it should work. Gotta love playing. .
I'll Try it Thank you.
flashing with flashtools, or wotan should wipe all left over date, cash, davlik, ect..
unlike using CWM to install update.zip where you need to do it manu.
or am i crazy?
I personally use only flashtool. That does the whole job.

No Cigar. still lockes up at first SE logo if i manualy want to get in, and if i use any software method from within android to reboot in to recovery it simply reboots back to android. Tried (flashing, rooting, cwm) with and without SD. This Sucks, what good is an Android device without CWM.
there has to be some way to get it to fff work.
Ok, so it goes like this.. Flash a new firmware, flash a stock kernel with CWM ( DooMKernel) through flashtool of course and the kernel through fastboot.. U done that?

I've had a similar experience today with a Arc S LT18i. Was on .42 (rooted and some system bloatware
removed). I tried an OTA upgrade last night, but this failed, presumably because I'd deleted some system apps. I then (without reading forums first - big mistake) upgraded with PC companion to .62 and THEN read that I couldn't root it again. After much reading of forums I found a version of LT15i .42 and flashed that - and rooted it again.
Then the problems started, I tried an OTA upgrade, and it failed mid-upgrade, giving me a blue arrow pointing down onto a screen with a yellow triangle of doom with an exclamation mark.
Flashtool didn't want to know for ages, then (fortunately) it suddenly let me flash back to .42. I've rooted it again, and any apps that weren't there have been re-installed. From what I can tell the LT15i (Arc) seems absolutely fine, with no visible difference from LT18i at all.
The question is - should I just leave it as it is and avoid risking bricking it again, or do I really need to try and get an ARC S version of .42 onto it with Flashtool, so I can upgrade to ICS when the time comes. If so, does anyone have a good link to .42 for LT18i pls? Ideally not from uploaded.to as that site was driving me nuts.
Thanks, and good luck to the OP who had similar issues.

That's cool. But with a locked bootloader there is no fastboot
So what I do is flash LT18i 2.3.4 .42 using wotan client, root using zergrush. Now at this point phone can be updated to .62 , using the updater inside the phone AKA - OTA, that way I end up with LT18i .62 rooted, Locked bootloader. It is very important to keep in mind that this method for update will only work if ALL oryginal SYSTEM applications are on the phone.
I tried To Iinstall CWM on a locked bootloader using : NAn's app from market, extreme tweeker, both CMD methods, and manual method using root explorer.
By now I can do it all with my eyes closed hehe, but still can't get in to CWM.
unlock your bootloader then flash doom's kernel

Until ICS comes out i dont want to unlock my bootloader
Is it posible to flash firmware .ftf (with flashtools) that is already rooted and has CWM instaled, on a locked bootloader?
also is there any way to flash CWM backup on to the phone, if i cant get in to CWM (convert it to .ftf) ?
Can someone post a link to LT18i firmware that is rooted and has CWM instaled. For locked bootloader (.ftf) ?
OK. So i'm a "GENIUS" LOL
i got a reason to belive that simlinks got screwed.
I failed to manchen that affter i upgraded the firm to 62 with pc companion, i tried to ROOT again but when: DooMLoRD zergRush did not work i decided to give a try SuperOneClick, then FlashTools... Kurrrr.
eaven thugh they all use Mr. zerg's methode there is another choice psneuter, if i uderstand correctly the two methods differ a bit.
So simlinks dont get whiped, nor deleated when flashing, or restoring with seus.
or am i missing something eaven simpler like "reflash with SD inserted But no SIM, take out battery(or DON'T take out the baterry untill rebooting the Phone twice" or some think briliant as such.
like the one for relocking bootloader in The SE X8.
Can i deleate the simlinks and what ever i belive wrong, then UnRoot, whipe, reflash, root, CWM?
Would that fix it?
the phone is usless without CWM
Unlocking BL is not an option for me, i'm afraid
SOLVED
Ok. I managed to install CWM using flashtool. Entering CWM no problems, creating backup no problem, but after restoring from backup the phone was freezing every time.
puppet13th was nice enough to help, it was not easy so THANX VERY MUCH MAN.
The problem is that my partition layout got messed up. this is how it is setup.

If you want to root, then you have to downgrade to .58 or older firmware(lower than 58). If you want to unlock bootloader, then firmware doesn't matter, bootloader is not in the ROM.
If you unlock bootloader and you need root and recovery, you can install a custom kernel(most of them already include autoroot and recovery), your ROM gets automatically rooted and you already have recovery aswell.
I Should hold the BACK button before turning on handphone OR hold BACK button after turning on handphone and then connect OR just hold the BACK button without turning on phone?
Confusing. Anyone can give some guide :crying:

Turn off the phone, hold down the Back button and connect the cable. Do not use the power button at all. When its ready, disconnect the cable and turn it on.

[SOLVED] How can I flash the Official Xperia S 4.1.2 on Unlocked Bootloader

Current Phone Status:

I am very much keen to flash the Official upcoming 4.1.2 for Sony Xperia S devices.

Please take out time to give suggestions.

Already Flashed ICS STOCK via FLASHTOOL on Phone but since its not MY COUNTRY specific
The build gives a few errors.
Just want it like the brand new as if its out of box with the New JB.

You have three options -
1) Wait until someone releases the FTF file of stock JB and flash it with Flashtool
2) Relock your bootloader and try to do a software repair/update with Sony PC Companion/SUS.
3) Use Sony's official Flashtool for unlocked bootloader to restore your device to ICS/update it to official JB.
In my opinion, don't relock your bootloader but just wait until someone gets the update and makes the FTF file. Meanwhile, you can use Sony's official Flashtool and revert back to stock ics.

Which new JB? the ftf you download and flash is the same that you get from PCC or SUS, just using a different way.
