Prototype Xperia Bootloader Unlocking?

I've got a prototype ZL which states that "Bootloader unlock allowed: Yes", however I have been unable to successfully unlock it. Anyone have any experience unlocking the bootloader on a prototype Xperia? Do you still get the unlock key from http://unlockbootloader.sonymobile.com/ ?

Do you know if the device is RED or BROWN? Have access to EMMA? Does Sony Update Service offer you to 'repair' it?

It is a brown device. I'll check the rest when I get back from work.

If it's BROWN you won't be able to unlock it as far as I know. Everything in those phones is signed with test keys and it probably requires another unlock code for the bootloader too. The unlock site probably generates them for RED devices.

Okay, thanks for your help! Too bad, I was so excited when I saw that the bootloader was unlockable...
If anyone has any ideas on how I can unlock, or get a key please PM me!

You're not even supposed to have a BROWN device There are very, very few out there and you might even be lucky. They usually get beta firmware quite soon, so I wouldn't even attempt to root it. Just keep checking for OTA updates and you might be one of the first with 4.2.2!

Oh, so the OTA actually does work? I thought it was just a place holder and everything had to be done through EMMA.

Well, not much is known about BROWN devices, but OTA should work. Perhaps not for all updates but you'll notice that from time to time it should offer some updates.
I'd give you my EMMA login to try some things, but my account level doesn't include BROWN firmwares If you want to verify completely if it is BROWN and what other specifics EMMA can find send me a PM!

I have a prototype xperia s rooting status does not appear.
can I upgrade from 2.3.7?

Nope! If you have a brown device you'll either have to get someone from Sony to update it over EMMA or you're stuck with the software you're running now.

You have a BROWN device (it's not a colour, it's an identification. BROWN = prototype, test keys - RED = retail, real keys). BROWN firmware is almost impossible to find, you should probably ask DooMLorD, he's the only one who in some rare occasions gets BROWN firmware.
But, the past has shown that it is nearly impossible to update them without help from Sony, so I'm afraid you're out of luck. You can always contact your local Sony Mobile branch to see if they will exchange your phone, as prototypes are normally not meant to leave Sony.

[Q] No access to Sony Xperia Z after firmware update to 10.1.A.1.434

Hi there,
I have updated my Sony Xperia Z C6603 yesterday to firmware 10.1.A.1.434. Before the update I did not have my screen locked trough a PIN code or anything else. After the update I am asked to enter my usual SIM card PIN when starting the smartphone, and additionally I have to enter another PIN, probably to unlock the screen. I never set up a PIN to lock my screen, so I cannot access my smartphone anymore in the usual way. Also the home button does not work anymore and the camera takes a lot of time to start.
Restoring factory default settings does not work, because the PIN code is also required in that case.
Does anyone have an idea what to do?

Download the SUS and run it http://www.sonymobile.com/gb/tools/update-service/. Follow the prompts and it will reflash the ROM. All data and settings will be lost though.

It worked..
Thanks a lot for the hint, using SUS worked well! My data is lost, but that doesn't matter so much...

Is this weird or normal?

I searched high and low for solution of my problem but i couldnt find the right solution to my problem that's why I'm starting this thread.
Phone- Xperia Sp C5302
Stock Kernel
Rooted
Philz Touch recovery installed
Nandroid backup made using TWRP
Tried to unlock bootloader- Problem starts from here........
Initially phone rebooted normally but couldn't detect sim and signal.
Then phone started rebooting after few minutes . Stay on for a while then reboot again till battery died.
Now battery not charging, phone showing no life, no led, no vol up+power, vol- power , vol up+vol down+power work
Tried everything I know plz help and plz explain slowly and calmly.
THANKS IN ADVANCE.
EDIT:
Used wall charger 2amp for charging left overnight no red led or anything as described in other posts
Connected to laptop left for about 4 hours no nothing.
Tried to connect in fast boot not detected.
Any more ideas guys at least give some pointer for what to do or is my Sp is actually dead ? And I can't restore my backup? Plz guys help
EDIT: Pressed the small button at the back and the phone came back to life YESSSSS........

Now the phone isn't showing imei no. or sim or network. But when restarted it imei and network came back magically. So I thought the problem is solved to confirm it I switched phone off again then switched on then imei and network gone again and also baseband isn't showing too (I'm sorry if it is the same thing I'm a newb to this stuff)
Then again I restarted the phone number it came again. I don't know what to do in this situation. I just wanted to unlock bootloader and install xenon hd rom in my Xperia Sp.

Try flashing stock ftf with Flashtool.
If the problem gets solved, then start with the new ROM.

Use the method answered by the previous post. But I will add into that
You can use the flashtool to flashing everything stock but please dont flash System and Kernel. If you flashed a custom recovery and want it to stay untick Fotakernel as well.
This should fix your problem without having to deal with the stock ROM.
But if problem persists then I would suggest a complete stock ROM flash.
Huge chance that the process of unlocking your bootloader is faulty. Are you sure that it went without errors? Anyway you might also wanto to try to relock and then unlock the bootloader again

@Zenith I left the phone idle for sometime now it's OK ish . I've made a nandroid backup but can u tell me plz which folder contains imei and other important stuff so I can make a backup of it too.
BTW I think my bootloader is not correctly unlocked coz pc companion is detecting my phone bravia engine is there gracenote is working. But in service menu under configuration I found: Bootloader unlocked: Yes.
Previously it was Bootloader unlock: Yes. So is it unlocked or not if not then how to unlock?
I've followed sony's official unlocking method.

You don't need to backup imei. It will stay the same no matter what ROM you use.
and You can use Titanium Backup to backup all your important apps and data. But do not backup/restore system apps.
and in the service menu;
"Bootloader Unlock allowed - Yes" means that your Bootloader is Locked, and you can unlock it.
"Bootloader Unlocked - Yes" means that your Bootloader is unlocked.
Bravia engine shouldn't work if your BL is unlocked, so something must have gone wrong in the process.
Follow what's said in post #4.

@Zenith Thank you for your wonderful suggestion i will do as u say. bt one big noob ques- Do i have to dload a ftf file to flash to stock cant i use my backup or someyhing from it to restore?
@TechnoSparks yeah i think you are right about my bootloader bt isnt there something to check if BL is unlocked correctly. Btw when i requested to unlock BL in fastboot nothing really happened apart from
<Bootloader > Unlock phone requested
OKAY [15.725s]
finished. total time: 15.725
Then restared approx every 10 min or so till battry went flat and phone being dead untill i reseted it via pin

Yes, you have to download the ftf file.
Use this one.
and don't use the latest version of Flashtool, use the "0.9.18.5" version.

@Zenith Thanks bro bt my model is C5302 will it be compatible?
And i just dloded 0.9.18.6 version. its not latest 0.9.19.0 ver is latest.
So do i have to dload again? (connection limited bandwith n slow speed)

@Zenith Sorry bro for bugging you again n again bt u r the only person who showed some intrest in this post and helping me.

You should flash ftf specified for C5302 then.
Download the C5302 variant that you prefer from here.
And try flashing with the Flashtool you have. If it doesn't work properly, then uninstall it, and install the 0.9.18.5 version.
Some members including me faced some problems on the next 2 versions of flashtool. So yeah..

Even you can flash C5303 ftf on C5302. I personally use Singapore variant .207. It has got least bugs and it is fast and much bloatware free.
P.S. Dont flash .201 it has got a lot of bugs.

Reversed screen rotation after fw swap c6916 (14.5.B.0.247) to c6906 (14.6.A.0.368)

Hi folks,
I've upgraded/replaced the original TMobile firmware (14.5.B.0.247) on my Xperia Z1s (c6916) by c6906 Customized US (14.6.A.0.368). Everything works fine except few things like:
1) screen rotation - when i try to rotate the screen into the landscape mode - it turn the screen in opposite direction/backwards. Looks like the sensor readings get reversed? It was working fine before the upgrade, hence it looks like a software issue. Any ideas how to fix it?
2) device memory is twice less but it is kind of expected because original Z1 has only 16 Gb of storage onboard. Is there any way to fix that?
Thanks.

ok, here is a "solution":
The C6906 "/etc/sensor_def_qcomdev.conf" must be replaced by C6916 version. The same applies to CyanogenMod 12.1. C6916 have different settings for few things.
I downloaded TMO firmware, extracted system.sin and replaced the file on my phone running CyanogenMod 12.1 - after reboot rotation works perfectly but it will get broken as soon as i upgrade the firmware

how did nobody catch that this dude managed to flash a different firmware on a phone that is supposedly NOT unlockable? Shefys, you need to explain exactly what you did. In another thread you said you unlocked your Z1s c6916 on developer.sony.com and i tried it, but there was no Z1s option. Followed the steps anyways by selecting Xperia Z1 but the unlock command failed citing not allowed.

hi, i wasn't aware that you cannot unlock z1s booloader. I just went to the developer site, registered, submitted my imei (as a Z1) and got a link/key to unlock it.... maybe my imei was lucky. Sorry, folks. Right now I'm running CM12 on my Z1s. Can provide photos if you want to
Before unlocking the bootloader, i was running C6906 official firmware on my phone because it was newer.

Yes please post pics. I tried unlocking my z1s as a z1 just like that but it didn't work. The fastboot command to process the unlock returned a "not allowed" error.
If you can get to the service screen, there is a section where it says "unlockable: no". (Or yes). Can you post a picture of that?
How did you get on the 6906 firmware?

after you take the link and after that you take the unlock code just have to unlock with flashtool:
1.) create a folder in the flashtool folder with your device code ... mine is : D:\Android\Flashtool\custom\mydevices\CB5A1WPPTA
2.) inside the folder, create a file called ulcode.txt , in the file just copy the unlock code
3.) open flashtool (be sure that your phone have enable usb debug and connected) and press BLU (bootloader Unlock)
4.) after that a window will appear with your code and the phone id, you select unlock and now you have the xz1s unlocked...
BE AWARE: in my case, the camera doesnt focus after unlocked and video just doesnt work...
for the rom, i think you could take it using xperifirm and installing with flashtool
https://www.youtube.com/watch?v=bbAfxL-oGjk

I'll have to try this and report back. I understand that unlocking the bootloader causes issues with the camera, but does the issue get resolved by flashing a ROM? Or does it stay broken?

I had same problem. I think you tried to unlock bootloader and relock it using wrong key.
Kindly follow the below steps.
DO NOT UNLOCK OR RELOCK WITH "fastboot"
use flashtool and go to relock bootloader.
upon locking reboot device.
if it do not boot, follow locking / unlocking twice or thrice..the tool must say "completed successfully"
reboot (automatically or manually)
It will work like charm. Do not go to service center, because those mules will look at screen and say "Display has gone" and it will cost RS 8000/- INR to get it repaired.
Cheers

Its been 4 days so you may have probably found a solution but just in case you haven't, here goes -
The other poster gave you a lot of info about bootloader unlocking but nowhere in your post have you mentioned anything about unlocking so I'll assume you are trying to recover from a bad flash or a malfunctioning system.
Which OS are you on?
Have you installed ZR (dogo) drivers along with fastboot/flashmode drivers?
Did you try another cable? Maybe another PC?
Are you letting go of the Volume button too soon before the flashing process begins?
Have you tried older firmware like KK or JB? For some reason I was having boot loop issues with stock LP just the other day so I flashed a KK firmware and it booted just fine. Even installed a custom MM rom later.

So true!
I once had an Xperia M that needed a power button replacement - they saw my phone had a custom ROM and told me they would have to "upgrade" the software whilst fixing the power button and with a straight face, gave me a number well north of 10K. I paid less to purchase the phone. It was the last time I ever went to a Sony service center.
Also I have unlocked 3-4 phones using Sony's procedure and I have had zero issues with fastboot. If I am not mistaken the unlock/relock option in FlashTool just automates the procedure so you don't have to type in those commands but either way fastboot mode/drivers are a necessity.
