xperia zl c6506 bootloop after bootloader unlock - Sony Xperia ZL

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.

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..

[Q] Help me unlock the bootloader of Xperia m dual!

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.

Unlocking bootloader killed my C1905, help please!...

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?

Xperia Arc S (LT18i) Can't enter fastboot mod, no blue LED and Insert Simcard problem

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.

[Q] Encrypted data

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.
