I'm using Xperia m dual c2004.I tried to unlock the bootloader. Several times using the procedure given in the Sony developer, did everything correctly. But the phone goes into a bootloop after which the only option is flashing the stock rom.
I tried unlocking the bootloader the otherway by using flash tool but it doesn't have my phone's drivers. And the link to download them doesn't work anymore (found it in a thread)
The are no roms for lb for my device (plz tell me if you know any)
I checked my bootloader status by going into *#*#bla bla code then service tests and security And the service Status was active which means bootloader is locked.
When I go to service menu and config my phone's rooting status is showing bootloader unlocked.buti don't think it is ul but it just has the Permissions.
Please help me I'm not able to flash roms because of this.

When you successfully unlocked bootloader you should go to bootloader mode with key combination when restarting phone and install custom recovery. Naturally without loaded drivers in computer it has no sense to try it.

I think you can keep your bootloader unlocked.
Just download an official ROM FTF file for your phone and flash it using Androxyde's FlashTool. It should debrick your phone. Then, you can repeat your experiments with custom ROMs.

i have tried using it but no change..

Hi guys,
I've tried everything, but after successful root I can't unlock bootloader and flash recovery mode. Fastboot is also not running. The stock ROM is awfully slow and I wanted to flash a new one... That is what I see when I enter the service menu (see the attachment) :/
Please, help :c
Xperia S LT26i (2012, I think)
Its just not allowed to unlock your bootloader.
Nothing more to say.
Send thanks to Orange, where you device is from.
You may try other ROMs based on stock one, but optimized. As said above you can't do anything about it. I would suggest you to update the phone to a new one with unlocked bootloader, SXS too old nowdays with it's S3 CPU.
Hello,
I had root and custom recovery installed. Everytime I try to unlock bootloader with code provided by sony, it fails and when I retype it, I get an okay message. Once I restart phone , it wont load past the design logo and just keeps restarting. I flash back to stock, try the same procedure and it does it again. What am I doing wrong?
Are you sure that your device says
Bootloader unlock allowed : YES in serice menu?
recheck it.it happened with my xperia pro which bootloader is not unlockable.
& make sure you don't have Bluestack installed in your pc.
It says yes and I have no idea what blue stack is. I am on windows 7.
Hi everyone
I wanted to try going from the stock Android 4.3 to cm12.1.
My phone was bootloader locked but unlocking was allowed.
So I followed the process on the sony website and got the unlock code and entered it.
Phone then refused to restart, stuck on booting screen.
Eventually using Flashtool, I found a stock rom and reflashed that, still wouldn't boot. Then I relocked the bootloader and now it boots again.
However, it now says sim card is invalid and refuses to let me join the phone network (I'm in Malta, using the Go network).
Also, I'm now unable to reunlock the bootloader as it says failed when I try doing so using fastboot and says it cannot be officially unlocked when using flashtool. Worryingly for me, in settings it now says "no" for unlock allowed (it used to say "Yes").
So now, I've got a phone that otherwise works normally again except that it doesn't actually work as a mobile phone! Please help me someone as Sony have already refused to do anything to help, their customer (dis)service people simply point out that once you unlock the bootloader - even if that itself causes the problem - they will no longer help you. Cheers, thanks Sony, no way will I ever buy any product from you ever again!
What a crap day...

i think you have missing something after unlock bootloader, and you can't give any wrong or false to sony. because you're do this with your vault and you're is vault your warranty. and sony have give you a warn sign before do this, and you accepted because you do it.
so no any vendor problem if you fail or your device is bricked.
after unlock bootloader, you need to reflash your stock rom again and do a full wipe data and cache from flashtool before flash any rom. after wipe and flash you can check your device is boot up perfectly without any problem. you only missed that. try to reunlock if still can, but try to unlock your bootloader using flashtool too.

Well on Sony's site it also says that any repair will be chargeable once you do unlock, so I would have expected them to have done something at a charge not to totally refuse to help at all. I accept what you say but I DID follow the instructions exactly, I unlocked the bootloader and rebooted it as instructed and from there it went wrong - refused to boot.
Anyway, I have tried several stock roms including even using the Sony tools and letting it do a "repair" reflash, all to no avail. "Sim Invalid" is what I'm left with and what I have noticed when flashing every stock rom with flashtool, what is missing from the "Wipe" list is cache, the only option there is "USERDATA". Is there something wrong with the flashtool perhaps?
Even when I relock the bootloader using flashtool (which I seem to need to do every time even after flashing a stock rom) it still seems to regard the phone as unlocked, or at least when you go the "BLU" screen it shows only the option to relock each time. Something has definitely screwed up here.
I got a UK stock rom via Xperifirm and used Flashtool to create the TFT from that. Still no joy. I'm assuming something is wrong with the sim lock, somehow, but how to fix this? I'm realising that reflashing stock roms doesn't totally return the phone to factory condition, so what am I missing here please? Is the phone totally stuffed now or is there still some way to repair it?
Ok so further to this, I just gone into service menu -> Sim lock and I see this:
[x] Network 0
[x] Network subset 0
[x] Service provider 0
[x] Corporate 0
[x] SIM 0
So is the phone locked or not? What does the x mean? The phone was previously fully sim unlocked as I bought it without a contract from Amazon. Is there a way to fix this please?
help me please
i have xperia m, after unlocking bootloader it stuck on bootlooping, i have not enable usb debugging...any way to fix it?
Hi guys,
I just got Xperia M from my friend to install on it some custom ROM and etc. but there is encrypted data and I cant do nothing with it.
I tried repairing software with Xperia Companion, but I get UEUpdateFailed UE_2005 error and cant get past it. I tried also to enter recovery, but there's no recovery. Dont know what to do, cuz I need to check if I can unlock it.
Thanks in advance
Hi,
I can't figure out what exactly is giving you trouble, so you might want to be a little more specific. So I don't know if this is helpful for you, but:
First, there is no stock recovery on the Xperia M. As long as you don't flash a recovery on it, there is none. So you won't be able to enter that.
Next thing, Xperia Companion is a software to update or repair the stock ROM. So you won't be able to flash a custom ROM with that.
Just backup the data (if the data is encrypted and still needed, you didn't say what exactly is encrypted) and use flashtool to flash a ROM.
I'm not sure what you mean with checking if you can unlock it. The encryption? The boot loader? SIM lock? If you can unlock the boot loader (and SIM lock status too) you can check with the service number, so no need to flash it for that. Or is the device not even starting up because of the encryption?
So I dont really know if I can unlock bootloader of that phone cuz I need to "you should confirm that it is possible to unlock the boot loader of your device by checking the service menu. In your device, open the dialler and enter *#*#7378423#*#* to access the service menu" but I cant cuz of encrypted data. When phone boots up it ask me for password, but I dont know it. When I tried to use repair function to flash stock software and then the encryption would be gone it gived me error mentioned before. I dont know any recoveries or Roms that I can flash on locked bootloader. Any sugestions ? I want to flash newest Lineage OS at the end.
Is it possible that the boot loader is already unlocked? PC Companion is not working with unlocked boot loader.
You can also use flash tool to check if the boot loader is unlocked or not.
how to check that in flashtool ?
You switch off your phone, hold the volume down key, connect the usb cable, then it should be recognized in flash tool. Then you click on the lock. It should tell you the state of your boot loader somewhere there.
