[Q] ICS on locked BL 4.0.2.A.0.62 - Xperia Arc Q&A, Help & Troubleshooting

I got a lt18i "unlock bootloader allowed: no" android 2.3.4 (4.0.2.A.0.62).
All i want is to have android 4 (or above) as long as it runs.
Can i get ICS, or any version 4.x or above,without unlock?
I read i can flash stock based roms those include android 4 or only 2.3 like i got now?
I also tried to update on PC companion but it doesn't eve detect my phone. My pc (win10) does detect it as "Xperia arc S" so all good there...
Idk what to try next :/
Any tips or direction are welcome, thx in advance!

Yeah, flash .587 firmware with Flashtool. That's it.

If you have an unlocked bootloader please research before you update! I know ota updates will brick phones with unlocked bootloaders, im not sure about ones from pc companion.

The pc companion shows new update but won't allow the user to actually upgrade with a unlocked bootloader.

I've got an arc with an unlocked bootloader.
Initially, I kept putting off the decision to unlock it because I didn't want to lose the DRM keys but I got it done by the Test-point method via Omnius, when they had an Easter offer (FREE). Who can turn down such a great offer? LOL!
I did it because it allows me to flash kernels and ROMs as and when required. My main inclination was the flashing kernel bit. Plus rooting becomes a cakewalk.

Test Point method can't be updated via SEUS?
and it cant be relocked right?
I was thinking unlocking via test point or flashtool ?
which do it better?
I haven't really tried updating via SEUS after that because I didn't want to risk bricking it.
It can be relocked. Blagus supplied the file you need to flash with Flashtool already. But then again, there's no real point in locking it.
Well, the main reason I went with the test point method is because I didn't want to lose my DRM files, which in turn would affect TrackID. But the latest version of TrackID which is available on the market works even with an unlocked bootloader so there's nothing to worry. You can unlock it via the official Sony route.
Unless your bootloader unlock status says no, there's no need to go for the test-point method.
And FYI, Flashtool won't unlock your phone. It's great for flashing ROMs, kernels etc.
How to know whether the bootloader is unlocked?
i using testpoint but not really sure it unlocked
Try hotbooting/flashing a kernel.

THANKS
I just noted that the fix is * 0.8.6.0
- Added Xperia U, P, Sola, Ion to BL Unlock plugin.
* 0.8.5.0
- Fixed issue with turkish regional settings (and maybe others we don't know)
No more need to change regional settings to see FTF content.
* 0.8.4.0
- Repaired TA Backup / Restore / Editor (broken by 0.8.3)
* 0.8.3 :
- Fixed an issue in firmware selector. When partition categorie or TA categorie are excluded from
selection, it was not excluded from flashing.
- Elf Extractor now identifies the program type included into kernel (Image, ramdisk or rpm)
* 0.8.2.0 :
- Fixed an issue where fastboot mode is not handled correctly under linux.
* 0.8.1.0 :
- Fixed an issue where loader is not found when using BL Unlock or TA Backup/Restore/Editor
- Progressbar when flashing was not showing right progress.

Why don't you go the official Sony route to unlock your bootloader?
Thank members on their post which helped you. It's always a good idea. There's a dedicated button, if you didn't notice.

Xperia Arc changing software need help.

Hi, I read the forums and I know to change the software on my phone I have to first unlock the bootloader. I follow the official cookbook and my "Bootloader unlock allowed" Says Yes (android ver. 4.0.4, kernel 2.6.32.9, build 4.1.B.0.587). I stop at point 13. When I try to indicate android_winusb.inf system returns me message that it can not find the driver in this directory. Also, when I try to do it manually. Can anyone help me?
Changing software does not mean you must unlock bootloader. Stock based ROMs work also with locked bootloader.

Ok so I have managed to install custom rom (yay) and now i have the question: can i flash back official firmware (tft file) ?
Sure with the flashtool or EMMA you can go back easily.
