Develop Bugs

[Q] Can anyone spare me moment to get me up to date re: ROM development?

Hi. I've been off the Arc ROM development scene for quite a few months but I'm back now and have been trying to read threads to get some idea of where we are up to now.
When I left, the boot-loader had been successfully unlocked and the phone rooted, Woohoo! Then we discovered that the SEUS threw its toys out of the pram if it met an unlocked handset, Bummer!
I see the situation re: SEUS and unlocked phones hasn't changed but I also see that someone has worked out a way to re-lock the bootloader.
Can we have a re-locked phone that is also rooted now? I would like to be able to use the SEUS updater but I want to keep my apps that require root access.
So if anyone can let me know what the current state of affairs is I'd be very grateful and have less headaches from reading miles and miles of posts!
Phil :-D

The namaste guide should help.

I know that you don't have to have an unlocked bootloader just to have root but what I would like to know is if I could unlock it to run some custom kernels for overclocking and then relock it for S E. updates ?

You can relock it and use SEUS.
But FlashTool will do it too without relocking it.

[Q] about bootloader

Hey guys I love my xperia but... The stock rom suckssssss. And cause my bl is locked most of the custom roms won't work on my phone...
I oppened this topic to know if someone knew what exactly is the bootoader unlocking I mean how it works (do bootloader unlocker delete and rewrite the bootloader or juste change a setting in it? Can it ne done with the developplment tool? Etc...)
Plz do not explain me that bootloader unlocking is the process that I need to install custom roms etc... I know what it is but I want to understand HOW it works.
Sry for my bad english if you can't understand something just ask me

to simpifly, you can think that the bootloader is like a safety-system. The sony makes it to accept their rom only and block others, like a kind of filter. When you unlock it, the bootloader will accept all roms, no limits.

Yup I know that but what makes this programm so difficult to rewrite? I know that its the programm that run before the os but why nobody founds a hack to unlock it without paying? Is it too hard or sony forbid free unlocking?
And again my question how does bootloader works? If someone know the code could it copy it?

It is for free. Sony created a website purposing for unlocking bootloader for those who want to unlock.
Its easy to unlock bootloader nowadays. When im was using my xperia x8, it took 8 freakin months to bypass the bootloader...

Oh boy, you missed a lot here. Take a look at guides in the general threads.
Its free to unlock bootloader
The imei way unlock (DRM data loss)
Testpoint unlock (no loss, fully safe), easier to relock and nobody can know if it was unlocked or not

[Q] How I can unlock my bootloader ? HELP

Hi everyone ! I have a Xperia Arc LT15i and I found out using *#*#7378423#*#* that I cannot unlock bootloader (Bootloader unlock allowed: No). How I can unlock my bootloader because I want a ROM like CM9 or JJ's Hybrid and it`s must to have bootloader unlock. Please help me with unlocking the bootloader, or please help to find a ROM like CM9 without unlock my bootloader. I want to say that I am not very skilled Waiting for more tips.

download flashtool then Plug in > unlock bootloader
it will guide you to sony's web page, copy paste the code and let flashtool unlock it

Actually JJ's ROM doesn't require an unlocked boot loader.

If you have bootloader unlock allowed:no standing, then you can't unlock it with Sony service, because your IMEI number is then 15 symbols long, so no way for unlocking bl without paying for services like setool

Hi,
If you have bootloader unlock allowed:no , you can unlock it with Omnius :laugh:, but is not free, 15€/unlock .
I unlocked my LT15i with Omnius, I had "unlock allowed:no" before.

So .. I can't unlock my bootloader, only if I paid :crying:

Setool & Omnius links?
you guys got any links related to this Omnius and Setool things? or other alternatives for Xperias stating that unlocking bootloader is not allowed?.. I had thought that if they say so, it was just impossible to unlock...

Unlock for free

just go here unlockbootloader.sonymobile.com

I'm starting to get angry I said and ludz179 in answer above you I can not unlock the bootloader so because the Service Info says Bootloader unlock allowed: No

was only giving info you say your phone says cannot unlock boot loader then from wat iv seen there is no way to unlock it.
but there is lots of roms out there that run well on none unlocked bootloaders and using new flashtool seems easy plus using DooMLoRD to root the phone .. I think the only way to do it would be to send it to sony service to unlock but knowing them you go no chance
just trying to help thats all

Can't help enquiring.You mention that there are several roms that are available which does not need to have the bootloader unlock.Could you give me the links please.

Xperia Play R800at Help with unlocking bootloader

Hello I need some help i really love this phone and i would really like to use custom roms in it.

There is a way to flash custom ROMs in FTF format but it doesn't enable fastboot and the bootloader remains locked. I have an R800at myself. The only way I know of to unlock is to pay an unlocking service that buys SETool credits.

Bootloader unlock allowed:NO!!!

I originally had an xperia c1905 but cross flashed c2005 FW onto my device. What i find really annoying is that when i open the configuration in the service menu i find out that i cannot unlock the bootloader, ie, bootloader unlock allowed no. I haver read online and i have researched it, but other posts were made in 2013, i thought id ask ahain in 2014. Is there any possible way whatsoever of unlocking my phone's bootloader? will i ever be able to do it? Are there any modern ways that i might have missed?
Guys please dont tell me to send my phone to sony and they will unlock it for me. I have already tried it, but fot no response from sony. I have even contacted o2( my sim carrier) and asked about information on how to unlock, they told me that they cannot comment on that subject.:banghead::banghead::banghead::banghead::banghead::banghead::banghead:
If u have any information, i need your help, thank you!

As far as I know, no way of unlocking your bootloader if it says no. You still can try the regular bootloader unlocking procedure method, the only thing that may occur is it not working...

Or it can brick the device just leave it for now and wait for the time being there might be a way of doing it if it gets found if not the new firmware that's getting released shortly might lift the ban off the bootloader

I have the same problem. Please somebody need to find a way to unlock it. I bought my phone from Orange. I flashed the stock Sony's firmware and rooted it. I can't flash any CyanogenMod :crying: My old Galaxy Ace hasn't got any locks or something, installing custom roms was easy, but on this phone for me it's almost imposible...

I stumbled on a post on the Sony Talk forums the other day that stated if you carrier unlock your phone (so you can use any SIM card) and then flash an unbranded ROM the bootloader unlock status changes from No to Yes. This statement was made by a moderator on the forums and I have no idea how well the procedure will work.
Oh, the post was regarding the Z too so I'm not sure if it applies to the M.
