hey guys, after much searching and finding different and none conclusive answers, i have have to ask this, bootloader unlock allowed:no i understand thats linked to the disabled fastboot feature which is somehow related to the simlock, anyhoo ive removed my simlock via nck, ive not yet performed a clean flash (if that would even work) but is there a way for me to now enable fastboot on my device or should i accept its a no go?
Some have claimed a sim unlock unlocks the loader but there is no proof, if you're locked youre locked, just get a different device honestly

Hi. I have a Rogers Branded Sim-Locked Xperia Arc with Gingerbread 2.3.3, and my goal for this phone is to get Cyanogen Mod 7 Beta 11 on it.
I read that in order to flash the custom rom I need an unlocked bootloader. I also read in order to unlock my phones bootloader I need to be able to enter fastboot mode. Unfortunalty I cannot enter fastboot mode since I got my xperia arc directly from my Carrier Rogers. My question is if I purchase an unlock code from one of the various websites out there, and then unlock my phone would I be able to enter fastboot and eventually unlock my bootloader and then flash cyanogen mode 7? Thanks in advance
No.
As things stand, there's nothing you can do to get your handset into FastBoot mode - only factory-unlocked handsets are capable of doing so.
Thanks but im still kind of confused. What about this? http://forum.xda-developers.com/showthread.php?t=1037874
And so with any custom rom coming out i will need an unlocked bootloader?
That's a thread discussing the possibility of trying to enable Fastboot on handsets that don't currently support it.
But to the best of my knowledge, no significant progress has been made.
So, has any progress been made? Am I able to unlock my bootloader now and get cyanagen mod? Or do I still need a factory unlocked handset cause of the fastboot thing
Have a read of the general and development sections. ;-)

i read it but im still a little bit confused, to my knowledge the only way of unlocking my phone to put cynagen mod is to pay someone to remotely unlock my phone?
Unless you have access to SETool, yes.

I recently purchased a R800 from someone on Craigslist. The phone is already rooted, permanantly I think since it is rooted after doing a factory restore. It is not sim locked, I believe its factory unlocked.
I tried to do the OTA update, which downloads, but fails to install. It appears to get about 3/4 of the way done, reboots and gives me an "update failed" message.
I wanted to unlock the boot loader, I got the unlock key from SE. I must of tried 10 times to get the phone to boot into fastboot mode, it NEVER does it. It simply boots up normally. I even got an app that makes it easy to reboot into restore or fastboot modes (just click an option and it reboots), however just like before the phone simply reboots normally. I even did a factory restore prior to trying the update... no go.
Should I try to remove the root access? Is this what is giving me all the problems. I was able to successfully install root explorer and titanium backup and both of those programs worked fine.

Edit: Title should be "Can not OTA or enter fastboot mode, root problems?"
Is your phone sim locked? Sim locked phones need to be unlocked before able to unlock bootloader or fast load. After you unlock bootloader make sure you never ota update.

Your phone has a locked bootloader and a factory lockout on fastboot.
Best advice to you is flash the r800a world generic 2.3.2 root it with gingerbreak then ota update. Use a program called wontanserver as its super easy.
Dont get anyone to remove your factory locks on fastboot until you read tons of threads on these fourms from the last couple months.
Ok, lets see....

My phone is the R800a. It was my understanding that this phone was never locked (factory unlocked). It came in an official Sony Ericsson box and has no carrier branding on it what-so-ever. It was not purchased through a carrier. It does have a weird stock data APN called "Telekila"?!?!?

Doesn't wontonserver require credits to run? How expensive does this get?
I didn't know the phone could have a factory lock on the bootloader. I did go to the SE website where you get the unlock key and it was successful in giving me a key... Well I shouldn't exactly say "successful", it did give me a key code to use if and when I can unlock the bootloader, weather or not that code is actually legit remains to be seen. I'm a bit skeptical now since you said the phone is bootloader locked from the factory. I though SE was allowing their phones to be unlocked. I recently unlocked my Motorola Atrix and was expecting to do the same with this phone.
Thank you guys for the advice. I love this phone so far but I can't wait to get a custom rom on it
It uses credits but they are free.
There are currently 2 gentlemen on these forums that can remove your fastboot locks and unlock your bootloader.
Have a look for thier threads on this matter
I would like to have this done now, so gentlemen, whomever is able to do this please message me and we can work something out. Im dieing to get a new rom on this awesome phone/game console.

If you need help with unlocking your phone contact Alejandrissimo he does Unlocks
I flashed the r800a world generic 2.3.2 rooted it with gingerbreak then ota updated.I get the same thing as DMpire , reboots and gives me an "update failed" message.
Is this because I removed some of the stock apps that came on the phone after it was rooted? Anyone know about this?
Does it matter if the SD card is mounted or not?
Removing stock apps then trying to ota isnt going to happen. Reflash, root, ota, then remove your stock apps
Is there any easy way to do this? can I reflash it as it has a locked bootloader, or do I have to get the bootloader unlocked?

I went to see if my bootloader can be unlocked from the sony website.
I followed the instructions by putting that code into my phone dailer.
Under the section if it says my bootloader can be unlocked, it says no.
Does this mean I CANT use custom roms?
Is there no other way to unlock the bootloader?
You can always unlock the bootloader, it's just a matter if it's free or not. It all goes back to whether you can use fastboot or not ( the tool used to flash kernels). If you bought your phone sim unlocked it more than likely means fastboot is enabled and you can unlock for free through sonys tool and be on your way to flashing custom kernels. If your phone is sim locked or you paid to get the sim unlocked by a code then fastboot will be disabled. So to rephrase: turn your phone off, hold the search button and plug it in to your computer, if the status light goes blue (and you're not on a CDMA one, r800x) then fastboot is enabled and you can unlock for free through sonys utility, otherwise you're going to have to use a pay service like this (~$24):
http://forum.xda-developers.com/showthread.php?t=1322827
And to answer your question, yes and no, while it's not possible to flash ROMs that use a custom kernel like cyanogenmod without an unlocked bootloader you CAN flash stock based ROMs through the recovery made for locked bootloaders.
I have an R800A from Rogers.
The LED doesn't go on at all when I press the search button.
When I goto sony's website, I go into the phone settings, where it says if the bootloader can be unlocked, it says NO.
You mentioned a paid servers. Is unlocking the phone by allowing it on another network the same as unlocking the boot loader?
No, that's sim unlocking. Confusingly a bootloader unlock will actually sim unlock you as well though, the difference between the two is a sim unlock is a code and the bootloader unlock is done through test points. So ya, if you didn't get the blue light your only option for unlocking is a paid service, sorry.
Well actually an unlocked bootloader allows booting of custom(unsigned) kernel images and can be achieved with various means according to the situation.

Which is what I said in my above post... And the only ways to unlock it are:
- Through sony's online tool if fastboot is enabled and you have an IMEI (sorry CDMAs)
- Or a test point unlock, such as setool2 or omnius, which will enable fastboot
Oh ok sry then, thought u were being general.

Thanks for the help. I contacted the guy about getting it unlocked.
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.

Ok so i have read many posts on XDA about bricked nexus 5x's and many others, sometimes the main probelm is the oem isnt unlocked. I myself have a Nexus 5x that is completely stock no custom recovery no root no nothing, i just update the phone, right now on Nougat 7.0 sep security update.
So my question is, should i check the OEM unlocking in the settings ? i will never install any recovery or root but i think by reading the posts, it seems like its a major problem if this is not checked, should i check it just to be safe ?

If you have issues in your current state they will most likely be hardware related and unfixable via software. But even locked you can completely reinstall the OS via sideloading an OTA or using the TOT method.
Enabling OEM unlock disables Factory Reset Protection (FRP). FRP is a security feature that prevents a stolen device from being activated. There is allot of info about it online if you wish to learn more.
So you need to decide if you want FRP or the ability to flash the factory images.

ok thx dude for the reply, nah i dont care about the FRP. so flashing factory images is easier right ? rather than sideloading or whatever this TOT method is...., and do most mobiles have a oem locked or unlocked ?

Sure, flashing the factory images is probably slightly easier than the other methods. Note that in your case you would need to actually unlock the bootloader to flash the images. With those added steps it's probably faster to sideload.
The Allow OEM unlock toggle has been around since LP I think. An pretty sure it's in phones that shipped with LP. It didn't automagically mean that the phones bootloader can be unlocked though. It should stop disable FRP though.

Yes, most, I think all OEMs leave the possibility to unlock the bootloader.
By default the bootloader is locked on most OEMs (Sony, Samsung, HTC, Motorola, even Nexus devices).
For Nexus devices it's a simple one liner to unlock/lock the bootloader which will also trigger a data wipe but. On Nexus devices it doesn't void your warranty.
For most other OEMs phones you have to follow some steps and usually get some kind of code in order to unlock the bootloader the first time. This will void your warranty!
If you don't know whether or not you should unlock/lock the bootloader, the answer is: NO!
It seems you're not modifying your phones software (Custom Kernel, Custom Rom, Root etc) and you seem to have no intention doing so. So it's not needed and even less "secure" than with locked bootloader. If you do, you should know that you have to unlock the bootloader in order to change the phones software.
Why would you want to unlock the bootloader when the only reason to do so is to modify the software and you do not plan to do this?
On a stock nexus there is no need to unlock the bootloader, you can even reflash your phone with locked bootloader with the stock software image.

yo dude thx for the reply, as i said in my first post, i saw some bricked nexus 5x (they didnt mod anything i think) that couldnt be repaired cause he had the option unchecked about OEM, that is why i was asking for like a safety precaution that if something goes wrong it would be okay cause oem could be unlocked then... what do u say now ? (and yea im not gonna ever mod anything in the phone, learned fom my last phone which i somehow bricked and a man fixed it for for 5$ )

That catch is if if you checked OEM unloking and chose to not perform oem unlock command now.
When something did went wrong afterward, you are able to perform oem unlock but it will wipe your data.
There is no point for doing it.
