Before you ask me, yes i have searched through lots of threads and i only create a new one because i still cant solve this. Perhaps someone here knows.
I have an Arc S with locked sim and "Bootloader unlock allowed: No"; and i've done hours of research, tried to get the unique unlock code for it and i did get it but i can't unlock it because as its bootloader state is "No" i cant get it into fastboot mode. So later i found i could only do it with that paid method of omni something which is about making a bridge in those contacs under the Sim.
So up to date, almost 2018, do i still have to pay more than this phone costed me to get a quite decent user experience with it? Because i wont.
I would really appreciate if anyone knows a method to do unlock BL with my current status. Thanks!
Edit. I gave up, im just looking to get a new GB rom that works in a locked device (now rooted btw) because flashtool doesnt seem to like 4.0.4 roms and i get system.sin errors while flashing any rom that is not 2.3.4 .
So does any of you know a rom that at least has a working download link? 70% of threads i search about this cointain dead links.
No Xperia Companion does not recognize the device (yes tried lots of things like debug on and off) and the PC Companion client that the phone comes with from factory always gives error while installing, so im pretty much stuck with ginger bread .ftf from the webs and flashtools. Thanks.

Problem with my Xperia Play
Hi, I have an Xperia Play that I have unlocked the bootloader on and installed a custom kernel. Everything worked just fine until weeks after I did these things the screen suddenly went black and the phone turned off. I have not been able to start it since it happend, when I try to boot the phone it will just vibrate and then nothing, the screen stays black. Even if it does not boot the computer recognizes it and I can flash roms with flashtools etc. I have tried alot of different roms and returned to stock kernel, I have even re-locked the bootloader and made a clean update with SEUS but without success, nothing happens on the screen. Have anyone had the same issue? Thanks! /David

hi, I just got a xperia play from a friend of mine. He rooted it and updated and it probably got bricked by the update. It doesn't do anything. When you push power it just buzzes. Now I don't have really that much information. but I think he unlocked the bootloader and flashed to root.
now for wat I have tried. I searched for solutions for this problem. That's when I came upon the flashtool. I tried flashing it simply with the generic_uk firmware. But it didn't do anything. Further research landed me upon a FOTAUnbrick tool. I read some of the information but I didn't really get it (most of the times I do know what i'm doing). So in my "nothing to lose spirit" i just tried it and guess what ? nothing. Now I know this is really vague and probably doesn't have a solution. But I'm keeping my hopes up for someone to bust this bugger.
Alright, here's the thing... My mk16i has a locked bootloader... Even still i ventured to attempt unlocking it through test point method and s1tool.
Apparently all steps worked, the s1 boot thing is now reported with an lowercase letter (just as mentioned in tutorial) which got me pretty hyped up...
but I just seem to be unable to get into fastboot mode, I do get the blue led for like 2 seconds and then is changes to orange and cell phone goes to battcharge mode (black screen with big batt charging icon).
The only thing I have not tested is first flashing the stock rom... I dunno if having custom rom has something to do.
Any ideas?

You've not unlocked it properly.
Well... I spent more hours into this last night, here's what happened:
Apparently test point method and s1tool can unlock the bootloader, I got notifications from s1tool, flashtool and Omnius that my phone was already bootloader unlocked... BUT it seems that the real limitation for "bootloader unlock allowed: no" phones is that fastboot is disabled, and searching through all the forums I only found one post of someone stating that no dev has been able to enable fastboot on these devices.
So, I even restored (relocked) the bootloader with s1tool in order to now try Omnius.
The good news is, Omnius works... I really have no idea how it did it, but Omnius did unlock my "unlock allowed: no" phone, and it uses the same test point method... the bad news is that it required me to buy an "Android single unlock license" for 15 euros... so I really hope it will be worth it.
That's all.
Good luck everyone.
Hi all,
I've got the Sony Xperia S and unlocked the bootloader and rooted it once and flashed it with the AOKP, but that didn't work, so I tried the Cyanogenmod 10.0 (Jelly Bean). In summary I think it was the wrong Combination of kernel and custom rom, because it didnt boot anymore and got stuck at the logo.
So I closed the bootloader again and installed the official stock rom from Sony, and all got fine, luckily.
With some more reading into right forums and better knowledge I got the right custom rom and kernel and tried to unlock the bootloader again, but suddenly it didnt work.
Message: Failed (remote: oem unlock 0xF (und noch mehr F) )
I did all with fastboot and the right adb drivers, the phone is installed correctly.
Yesterday I asked for my problem in a shop and the guy said, that the bootloader of any Sony device would close completely, if the (right or wrong) unlock code is used for too many times (like the limit of 10 times).
If he's right, I've got a big problem. But can't I open it with an alternatvie method? Or is there just any mistake?
Thanks for any answer
Chriszo
i dont know, but ive already relocked and unlocked many times without error ,
try to do it again and be sure to input the correct 0xKEY
CM10 contains it's own kernel so could never be a wrong combination of rom and kernel. Did you actually unlock the bootloader or just root the phone? Sounds like your bootloader was locked and you were trying to flash still

Thanks for the answers.
I don't still know what constellation I really tried to instal the kernel and firmware, but I think it was an advanced stock kernel and then the firmware of the aokp. After that I tried the Cyanogenmod, but the device just didnt boot, there was only the logo.
I remember to have taken the kernel named ics17.elf and the advanced stock kernel with the official 4.0.55 build number.
The the device was rooted and the "sd card" was not wiped, but the data of the apps were deleted.
So the bootloader was open because the kernel can't be flashed with a locked bootloader.
After that I flashed the aokp and then the cyanogen mod.
Because of no booting I relocked the bootloader and installed the official firmware from sony.
Since then I try to unlock the bootloader with this damn error
I try to unlock with another computer. Maybe it work and its a simple solution. To unlock my bootloader i need to use my wife´s laptop.... i try in my compputer many times, install drivers, uninstall, and a lot of tricks but fastboot give me "error" all the times... lol
I just chatted and called with the Sony support (nice to hear great english at the phone ) and again got to hear, that they aren't able or allowed to give any information about the bootloader because of the possibility to loose the warranty of the phone.
I dont know really where my problem is but I think the code is not working any more, although I cant imagine of that
Is there any other way to do that? Or do I just do a stupid mistake ???
Thanks

No no no!
Another guy on xda did it with FlashTool on locked bootloader. I was able to do it until the logo...
Apparently you only can flash roms I think, not?
Anyway Sony supports Open Developer Community as well, they give you info about bootloader here:
unlockbootloader.sonymobile[dot]com
No, I cant flash any rom, therefore I need an unlocked bl. And the stock rom from sony isnt available in the internet, just with the Sony-mobile-update-service.
Well, of course I tried the way Sony dicribes on this webside, as explained below -.-
Got the solution ??
Hey I have the same exact problem and i did the same things as you did ... did get a solution?? please inform me if you did.....
Is there anyone (Besides guys that charge $24) that have been able to Successfully unlock the boot loader on an AT&T Xperia Play?
If there has been, could you let me know? I know that there's at least more than 1 way to do so w/o paying. Just like with the Toshiba Thrive, it took forever to find out how to root and unlock the boot loader, and some guys found out and started charging people for them to do it, then one guy found it out and was generous enough to do it for free(like it should be). I got my Xperia Play in a trade with an iPhone 5 for my Nvidia Shield about 3 weeks ago and would like to test some roms on it, but since it's AT&T I can't get into fast boot or anything close to it, just an orange light with a charging battery on screen.
If anyone can help, let me know. Thanks.

So the gist of it is, first you need to flash the stock FTF for R800a with Flashtool. Then you can unlock the bootloader yourself using the Omnius tool & the test point method - it was like $12 for me when I did it, but at least you can do it yourself. Once the bootloader is unlocked, you can flash back to stock FTF for R800at.
However, pretty much ANY of the ICS/JB ROMs you flash will need to flash JUST THE BASEBAND (exclude everything else) from the FTF for R800i 4.0.2.A.0.58 EnhancedV2 which can be found here:

Hello.
I've searched forums and found some threads like this but my problem is a bit like them and a little bit different at the same time.
Sorry for my ENGRISH
I have Sony Ericsson Arc S, (LT18i). My brother bought it from UK and bringed to me, to Türkiye (Turkey). As you guessed, Turkish simcards didn't work and my brother gave money to a mobile phone seller to unlock it's simlock. After this, we able to use phone with Turkish simcards in Turkey.
The other day, after a couple years, I wanted to install a custom ROM on my Arc S.
This is how everything started.
I searched XDA forums and took notes. How can I do it, which programs needed etc.
Preparing
First, I did a factory reset.
After the phone opened, I changed usb connection to MSC, allowed Unknown sources and opened USB debugging.
I installed Flashtool 0.9.10.0. I readed a couple posts about that, previous versions gives no errors.
Under /drivers folder I found a driver package. Installed it with just Flashmode, Fastboot and Sony Ericsson Arc drivers selected.
Pluged in my phone and checked if it's drivers installed or not. Success. I can see my phone in device manager.
Installing
I readed a few guides and they say I have to Unlock bootloader. So I clicked Bootloader Unlock option in Flashtool. Followed the instructions, gone into flashmode, restart, gone into fastmode with pressing menu button and plugging the usb cable etc. There was a window with my IMEI and I followed the instructions and I get a code (long, including letters and numbers) from official sony website. I entered this code to that window and it said my bootloader is unlocked.
After that, I rooted the device. No errors.
Installed CWM via Flashtool. No errors as far as I remember.
AND THIS: Flashing a ROM. I found an Android 5.0.1 ROM and it said that I had to flash boot.img. So I did. I mean, I tried. I GOT ERROR. And, BUM. Something happened and I couldn't open the phone.
After a search, I found a solution says using Sony Companion may restore the phone. I tried this. Follow the instructions and my phone opened with ICS 4.0.4 instead of old version, 2.3. And now, it says, INSERT THE SIM CARD.
I searched the forums about 2 days and didn't find a solution to this. It ignores my sim card. Then, I saw a secret code about simlock and bootloader status and entered that code *#*#7378423#*#*
Under Simlock option,
They say there must be X's. At least the first one must have X on simlock screen but it hasn't. And there are all 0's. No X's, and zeros. So this is bad i think.
Under Configuration
In configuration section, it says Bootloader Unlock Allowed: No. As far as I learned from XDA forums, that means bootloader is locked again. Because it must be unlocked or unlock allowed: yes.
So i tried to unlock bootloader again. I had no idea what I've done. First, it said go flashmode. Done. And it said go into Fastboot. I couldn't. No Blue LED.
You see the thing? => Flashtools says go Fastboot to run Bootloader unlocker. I can't. Forums says I have to bootlocker unlock to enter fastboot. Bootloader unlock to enter fastboot. But enter fastboot to boot unlock. Wow.
Lastly, I tried flashing custom TFT's to see if it can flash or not. IT FLASHED. I can flash STOCK TFT's, even a KERNEL i downloaded from here. I can Root, install Busybox ( I don't know what is it haha), Install CWM 5.0.
But since it can't see my Sim Card, i didn't try to install custom ROM.
What I have to do? How can I unlock to simcard lock if it's locked? is my bootloader locked?
My brain hurts.
I wrote all things because it's easy to solve a problem with more information. So a few things more:
I use Windows 10.
I didn't use original cable at first. But you know, no errors now. It's not important at this point I think.
I unistalled mobile device from devices manager and delete the driver. I installed inf file from sony website and selected it for ADB driver. It says now Sony sa01102 ADB Interface Driver. If Fastboot needs correct drivers, I installed from it's official site, offical one.
I didn't tried another computer because again; no errors from Flashtool.
THANK YOU ALL.
I maybe copy this to other websites.
About Loader.sin Error
I did get Loader.sin Error a few times. But when I use previous Flashtool version, there was no loader.sin error.
"In configuration section, it says Bootloader Unlock Allowed: No. As far as I learned from XDA forums, that means bootloader is locked again. Because it must be unlocked or unlock allowed: yes." It means you cannot unlock bootloader! Its not possible , your phone is locked , i mean you cant run fastboot mode , its locked , install stock firmware and thats all , you cant install any custom firmwares as Cyanogenmod or custom kernel anymore. If you can't understand it sorry because english is not my main language.
