In brief:
I recently upgraded to the r800at on AT&T, and I've already come to root the phone on .270 using flashtools, (can't get OTA update due to specific circumstances, irrelevant) and I'm confused on the status of whether my bootloader is locked or able to be flashed with custom roms/recovery. After using the instructions at (unlockbootloader.sonymobile.com/instructions), I was stuck after the first few steps, as in the configuration file, the only items displayed were the IMEI, IMEI software version, Speech codecs, and working bands. Picture: (i.imgur.com/GTBLE.jpg)
I've done my best to try and search the forums for the same problem that clarify it, but due to either this being an isolated incident or my own incapability, I have been unable to locate a solid answer. Can anyone provide clarification?
Thanks.
Type the following in the dialed *#*#7378423#*#* then go to Service Info -> Configuration info. Where it says bootloader unlock allowed will probably say no which means you can't unlock it the Sony way. You have to do the test point method and pay one of the few members on the forums to u lock it for you. You are paying for the credits used for the software to unlock the phone.
Search the forums a bit. There is tons of info on unlocking the r800at.

I did this exactly as you stated. As posted above, the only things showing are the IMEI, IMEI software version, Speech Codecs, and Working bands. There's no info showing via the bootloader. I was just curious as to what that meant.
I just checked on mine and I don't see that there either. My bootloader was already unlocked. Odd. I wonder if that goes away once the bootloader is unlocked.
You could always check and see if you have access to fastboot.

Recently got an R800at from ebay that was unlocked (first ever smartphone, woo). I was able to use my dad's sim card no problem, and dialing the number for the settings window showed no column stating whether the bootloader was allowed to be unlocked or not - according to some threads I've read, users who had unlocked Plays also had the same experience, leading me to believe my bootloader was indeed unlocked.
After following the Gin2Jellybean guide, I managed to brick my phone today (stuck on sony ericsson text), but restored via downloading a stock rom off the internet and installing via flashboot (the SUS and pc companion were having issues - they said no software was available or I had the most up to date software).
Now it seems I goofed up a second time; I was following the Gin2Jellybean guide again when I realized I was following the version for locked bootloaders! I was already on step 4 to install CWM when I realized this, but I decided to just try to install doomlord kernel v14 as per normal and hope that the doomlord root toolbox from the locked bootloder tutorial that I had used wouldn't conflict with anything.
Upon reading the directions for doomlord kernal v14, I decided to double check that my bootloader was still the same as yesterday (before I had bricked my phone). As it turns out, I now have a column for bootloader, and it says unlocking is not allowed. So what's the deal, was my phone's bootloader actually unlocked in the first place, and if so, why is it not unlocked now? According to this thread (http://forum.xda-developers.com/showthread.php?t=1720201), bootloader unlocking is permanent.
Here's the link to the guide I'm following: http://forum.xda-developers.com/showthread.php?t=1631144
Gonna go take the dog for a walk now and listen to some calm relaxing music... Hopefully I didn't screw myself over here.
So when you typed in that code, you got told that your bootloader can't be unlocked? If this is the case, you would have to pay to have it unlocked by someone such as Alejandrissimo. It may be that your bootloader was never able to be unlocked as i can't think of why that would change

SIM unlock and bootloader unlock are two very different things, as you've probably found out by now; the r800at models can't be bootloader-unlocked with the free Sony method; you're going to have to pay someone, and it'll cost you at least $20. If you got one of the phones from the guy selling them for $105 on eBay, I'm pretty sure those are SIM-unlocked only.
If you don't want to pay extra, there's nothing wrong with keeping it locked; there're a few ROMs you won't be able to use, and you can't change your kernel, but for the most part you should have a good experience.

Everything you said seems to be spot on. The only thing that doesn't add up is why there wasn't anything saying one way or the other whether my bootloader was unlocked yesterday, but now today there is.
And ya, I probably won't end up paying the $20; basically I just wanted to remove bloatware and have a nice looking interface. Besides the question about why there was nothing on my bootloader yesterday, can you say offhand whether my sim should still be unlocked? I don't have one nearby to test.
Go to the dialer and enter *#*#7378423#*#* and go to Service Info -> SIM lock. The bottom line should say SIM 0 if it's unlocked. As for why it wasn't showing the bootloader status, I don't know. I was having the same problem yesterday, on multiple ROMs, so perhaps it was added in some specific update.
Dear all :
Recently I bought an Arc S and want to unlock its bootloader, however it comes up with unlock fail. Really frustrated for that... Please give a helping hand
1. I 've tried the unlocking on three different machines Win 8 x64 Win7 x64 Win XP SP3 x86,
all showed Version 0.3 finished and oem unlock fail
2. I 've checked the IMEI code when the Arc S is on GB and ICS, both showed the same 15 digits IMEI.
3. I used the first 14 digits of my IMEI to apply the unlock Key by different explorer (IE,Firefox,Chrome), all showed the same unlock key
4. Track ID is functioning properly so I think the machine is not unlocked before
5. Bootloader Unlocked Allowed : Yes
6. Done all the methods stated in

Bootloader & SIM Unlocking:
PLEASE NOTE: The ONLY WAY to Sim Unlock your Phone is to PAY for it, so do some Googling and read which services have been recommended in the past.
PLEASE ALSO NOTE:
If you're Phone was manufactured AFTER a certain date, 12W11 (look under your battery for a similar number) then the Testpoint method no longer works, and People who have had Phones returned from a Service Centre are reporting that they can no longer unlock via the Testpoint method either.
- Know Your Android Bootloader - What it is and Why it Matters
There are three ways to Unlock yours, the Standard/Official method (For SimFree/Un-Branded Phones) which is explained HERE, (PLEASE NOTE! - You loose DRM when using the official method but not with the TestPoint) but if your Phone came from a Carrier then chances are (99%) you won't be able to use that method. There is a simple method of checking if you can or not which you'll find HERE.
Standard Unlocking:
Then there is the TestPoint method...
TestPoint Unlocking:
Two members - Alejandrissimo or Jinx13 offer a Remote Service which isn't free, but cheaper than anywhere else on the net, and when you take in to account you will also SIM Unlock and retain DRM using the Remote method it's worth it.

Mine states 12W48, but I don 't think it is branded or simlocked since I bought it from a local retailer in Hong Kong.
So even though it says Bootloader Unlocker allowed : Yes still might have chance that It is simlocked?
You should be able to unlock by the official method, which you wrote about.
You said it showed "oem unlock fail". What's the full error given in the log?
Guess I found the answer.
I think this is a refurbished Arc S and the IMEI code is a fake one.... "awesome" china goods....
Any method to unlock the phone given that YOU DON 'T KNOW your true imei?
Under the battery or in Dialer *#06#.
You don't get my meaning....
What I mean fake code is that
1. The IMEI stored in the phone
2. The IMEI stated in the sticker and box
are ALL FAKE.
I found that there are a lot of similar cases in some other Chinese Androids. They figured out the reason behind that is the IMEI code is modified by retailers (Well I don 't know how can they do it, but it seems very easy to them) and the IMEI you extracted by all means from the machine is no longer the original one...
Any method to unlock the phone given that YOU WILL NEVER KNOW your true IMEI?

Yes,
you can use test-point method to unlock which requires no IMEI number.
Oh boy..... What is going on....
Wait a second. This makes no sense. Firmware reports one IMEI, but phone is actually using a different one? How do you even use it then?
That 's why those chinese refurbished "brand new phone" are so awesome...
They claim that the phone is brand new and the evidence is that the IMEI stated in the phone , the box , the sticker are the same. However you use that that IMEI to unlock the phone and eventually fail. The only reason is that this is a refurbished one and those IMEI are fake.... There are numerous cases in the Chinese Android Forums.... You even can not unlock it by brute force (test point method)....
In that case we are not talking about Xperia Arc, but a chinese copy of this phone. Thereby this method does not work for you.
Sent from my LT18i
No. The machine itself is ORIGINAL, you can do a official update and apply the original ftf. The retailers received those second-hand goods and then INSERT A NEW IMEI and forge those stickers for the box and the machine so that the retailers can claim that it is brand new. I searched in the forum and found that some retailers will insert the same IMEI in to a batch of refurbished phone =.=
There are numerous methods for unlocking the phone but all resort to the IMEI, what if you have a fake IMEI =.=
Hi,
First off sorry for any reposts is didnt know what else to do after reading forum posts for hours and hours.
So heres the Crack. I'm tring to flash CM 9 onto my SE Xperia Arc (LT15i) and so far here is what i have done.
dialed *#*#7378423#*#* and found my phone is BOOTLOCKER ENABLED=NO
Asked o2 for a Sim Unlock Code
Entered that unlock code sucssesfuly
re dialed the num in point one to find that is sill says no
tried putting into fastboot anyway (as suggested by users in another post)
I'm other things i did where email and ring o2 both gave me no help and email sony mobile and recive no reply after now a week and a half
does anyone have any tips on turning the boot loader to say yes as that is my only hurdle to rooting this phone, i believe it is possible as i read a page on the sony forums sayinf a spansih comanpy called movistar was offering it for there customers however i then though one last ditch attempt with o2 on there forums where the customer service lady flatout refuses knowlage of a bootloader.
in summery a) sorry for rambling a little b) is it even possible by any means to change the UNLOCK BOOTLOADER: NO to UNLOCK BOOTLOADER: YES. and if so how?? c) sorry again if this is a duplicate post i didnt know what else to do at this stage.
If the SIM unlock was successful you should be able to unlock your bootloader. Just follow the steps here:

Actually no. Just removing the SIM-lock does not enable fastboot (and does not change Bootloader Unlock Allowed, it still stays on No).
The only way to unlock bootloader is by using test point method, if your phone is manufactured before 12W11 (11th week of 2012). You can check it under the battery. If your phone is manufactured after 12W11, then you can not unlock your bootloader and can only use stock-based ROMs.
There is no known solution to this at the moment and due to lack of interest by developers, it is highly unlikely someone will work on it.
It seems like i found the solution.
you have to pay £10 via paypal on phoneunlockserver(dot)com
and he will log on to you computer via himatchi and you put your tweezers on the test point (for the arc its under the sim card) and then plug into the usb and he flashes a kernal or something.
i havn't tried this out yet but if anyone has please let me know how it went

This is called the test point method. It only works on phones manufactured before 12W11.

No need to remove SIM-lock, just find the guide to unlock bootloader via test point method using S1Tool. Follow the guide and it should work.
You can do it pretty much by yourself, no need to pay, if I remember correctly.
Hi everyone !
Hope I'm not making any double post but I couldn't find any explanation for this very specific situation.
After thorough research it, it seems that most of samsung devices has a secret setting called "OEM unlock" that we have to use to do the first step of rooting the device. In some cases that setting is missing but can be displayed again by some "date settings" tricks or waiting 7 days. In some other cases which seems to be mine, the "OEM unlock" setting is simply removed by probably the carrier of the phone and can't be reinstated.
In that last case which seems to be mine, I can't find any precise information wether we can or we simply can't unlock bootloader by other way and therefore root the phone.
Could anyone enlighten me ?
Thank you very much in advance !

I assume you know that the OEM unlock toggle is in the developer settings? To enable developers settings, tap build number repeatedly until it says you are now a developer. You will need no fancy trick to show it as the lock that hides OEM unlock, only came out in oreo. I don't think carriers disable OEM unlock on Samsung's but I could be wrong. Lastly, if you get it figured out, go over here to the right thread and get it rooted. Good luck! https://forum.xda-developers.com/sa.../how-to-root-twpr-flash-a300fu-a300y-t3494362

Thank you for the answer.
You assume right. I enabled developers settings first, saw that I didn't have OEM unlock option visible, then started to look about this issue. It is quick to see that in many case, even for phone not on OREO (I'm with Marshmallow 6.0.1), this OEM unlock is missing. But based on internet available data, it seems that in most of the case there is a trick to make it visible again. It is a sort of samsung security against thief that hide this option for seven days.
The trick didn't work for me and by looking more I saw that some people seems to be facing the same situation as mine. Some suggest that it is disabled by carrier.
But I couldn't find a solution anywhere for that context.
My question remains.
Here is a more detailed explanation :
from https://www.howtogeek.com/239798/how-to-unlock-your-android-phones-bootloader-the-official-way/
""There are two kinds of phones in this world: Those that let you unlock your bootloader, and those that don’t.
Whether you’re allowed to unlock your bootloader depends on the manufacturer of your phone, the model you have, and even your carrier. Nexus phones are all unlockable by nature, and many phones from Motorola and HTC allow you to unlock your bootloader through a similar process as the Nexus.
Other phones, however–and some carriers–don’t allow you to unlock your bootloader the official way, which means you have to wait for developers to exploit a security vulnerability if you want to root and flash ROMs. If you have one of those phones, this guide will sadly not help you.
The best way to find out which category your phone falls into is to browse its section at XDA Developers. If you have an HTC or Motorola phone, you may be able too research its unlockability on HTC or Motorola’s website. If it doesn’t support unlocking, you’ll have to use an unofficial unlocking or rooting method, which you’ll usually find on the XDA Developers forums.""

The Galaxy A3 2015 (SM-A300FU) has no OEM unlock as A3 from 2015 don't even have FRP Lock, neither it has RMM state. That means there is no lock which prevents you to flash any custom binaries like TWRP recovery with Odin. You'll only lose access to knox apps/services (because of knox 0x1), rest remains the same.

Hi !
About my device, here are details :
Samsung A300FU
Android 6.0.1
BASEBAND VERSION : A300FUXXU1CPH3
Build number : MMB29M.A300FUXXS1CQD5
Carrier was French company called Bouygues.
About bootloader lock or not, I can see on various website that many samsung are bootloader locked but can be unlocked easily by this OEM unlock option. Sometimes it is missing. Two reasons for that : Security check that is removed after 7 days or apparently permanently removed by carrier or geographic area control.
If i'm in that last case, is there any other solution to unlock the boatloader ?Or the phone is just unrootable. It seems strange to me that some phone are just unrootable.
Thanks again !

Hi !
Thank you very much both of you for your help. Indeed there was no OEM unlock.
Many posts talking about OEM unlock existing on that A3 and the fact that I couldn't check if it was locked or not using the two methods advised (with adb or with a special code to dial up on the phone interface) led me to stop at that step to be sure before going on.
It is advises not to root a divise with a bootloader locked to avoid bricking it.
Anyway, trusting your input I did the whole process of rooting and putting a custom rom and it's all great !
My wife brought me this phone from eBay. The guy made out he was in London when in fact he was based in Singapore. Anyway tried to unlock the bootloader and it is greyed out. I've read sometime a Verizon phone locks the bootloader so it can't be modified. How do I find out if I have this kind of phone or what do I need to do to enable the OEM unlocking function.
If the OEM UNLOCKING is grey,you pretty much have your answer.
There are two kinds of "locked" that describes Carrier phones.
1) locked to only be used on that carrier's network
2) locked to keep the bootloader from being unlocked and the device rooted
Yours is likely only #2 above, as I believe VZW doesn't #1 lock their 4G/LTE devices any more...
There is also a way to check the model number, I think, that confirms it is a Verizon locked (unable to unlock the bootloader) variant, but I don't recall that process.
Thanks for your help
