Unlocked Update Question.

Hi my orange phone is now unlocked and debranded. If an update comes out in the future will it just update as normal or will i have to use a goldcard and also will it stay unlocked.
thanks
Dion
Other threads suggest keep the Goldcard in when doing it but they also say you will get locked again...another reason to get unbranded handsets!!
So i take it the only way i can fix this is to install an orange update in future.
Yes? / No?
By the way, does anyone know when we are gonna see an orange Uk rom. Or is there one out there somewhere
If the unlock was done via the IMEI number I would think that, even if the update locked the phone, the unlock code would work again.
That's my hope anyway.

[Q] Can I unlock my Desire before I use the official update?

I was wondering if I use the Unlock Utility found here will it mean I can't use the official GB update?
not too sure but beware if you update it to the official 2.3 you will not be able to root or S-OFF it due to the updated Hboot!
I don't want to root just in case it bricks the phone so I thought this will be a good alternative.
You can use Sim Unlock no matter what you will do in the future.
In a previous thread someone mentions that you can't use the sim unlock after you update. I was wondering if I use the sim unlock before I update will the unlock still be there or will it get rid of it?
Also I heard you can't update a rooted phone, does this unlock require root? OK This doesn't require root.
No, when you update, you must run sim unlock utility again, what you cannot do when running the official gingerbread.
You can run the update on a rooted phone. But after the update you will loose root access.

Yeah I did it anyway it didn't work.

Pretty much every xperia play can fastboot...but if you want to test your bootloader just open fastboot,download clockworkmod and test it,if it doesn't work you can update via OTA (update center on your phone) and keep root

can anybody please guide me in updating carrier unlocked r800x to 2.3.3 from 2.3.2 in order to root and then further install custom roms etc.
Currently i'm using reliance communications(India) as a carrier for this phone.

I'm still waiting for an expert suggestion on how to go about this. Someone please update me on this
either updating to 2.3.3 or rooting with already running 2.3.2, i hope there is a way.
Nevermind, i managed to root my phone.

Upgrading from .42 to .62

I have a UK Xperia Play on .42 firmware with CWM recovery and root provided by Zerg Rush.
I've heard that I need .62 to install some of the custom firmwares.
.42 appears to be the latest firmware I can get OTA. I'm not sure the best way to upgrade to .62, do I need to go via .58 or similar.
Does it matter that I have a UK phone?
Is it possible to preserve my settings?
Will I need to re-root at any time?
In the long run I am looking to install DooMKerneL and probably something like Jokawild.
You have to flash the ftf file for your phone
Here is a link to 99% of them

If you install a new firmwares. Maybe you'll need to root it again..
But since the devs makes the pre-rooted custom ROMs, you don't need to root it anymore

I don't have an unlocked bootloader. Is this required to install a custom ROM even if I have root?
Is there any disadvantage to unlocking the bootloader?

No unlocked bootloader = no custom kernels/ very limited to roms
Only disadvantage is it voids your warranty, but being that you have root, you have no warranty anyway lol
I was in the same position as you. I wanted to get a custom ROM and be able to overclock my phone. After a few annoying errors, I finally got it up and running
Basically, your going to have get your phone into flashmode and then flash the .62.ftf file on your phone. Congratualtions you now have .62FW (although youve lost root).
To get root on .62 FW, your going to have to flash a custom kernel (I did DoomKernel v14). To flash a kernel, your going to have to unlock your bootloader. After unlocking and flashing the kernal, your phone is now rooted.
And plus the positive side Ive heard is that you CANNOT brick your sony eircsson phone. (well you probably could but there is a very very slim chance of that happening).
Thanks.
It seems I can't unlock via the regular Sony way as Unlock Bootloader is set to no.
I think I need S1Tool or something similar (maybe something I have to pay for) to get my bootloader unlocked. I'll check the forums a bit before I ask any questions that haven't been asked before
i did it via omnius and it work great, i just payed 19.76 for one single unlock credit on gsmserver
not sure why people say that root voids warranty.
i have ATT play 4g and it was having hardware issues, so i flashed the stock ATT software back and took it to the store. i got a "new" one in the mail two days ago.
I also sent my rooted xperia play that had the slider broken to CLARO El Salvador and they repaired it (They flashed their ROM again XD)
Now i have unlocked bootloader but who cares i have premium insurance
Any modification to the software voids the warranty..
Update:
I downloaded s1tool and connected the test point to the ground. Everything seems to have worked so I am guessing my bootloader is unlocked. Is there anyway I can verify this, or should I just attempt to install a kernel?

Try to put the phone in flash mode (green light) if it recognizes it, it's unlocked. I think there is a sequence or symbols/numbers you can do to check it, but idk what that is since im a r800x
To check your unlocked bootloader you need to dial: *#*#7378423#*#* , then go under, Service info > Configuration > Bootloader unlock allowed: Yes/No.
