Bootloader unlock page under maintenance

I was planning to unlock my bootloader today. When I tried to open the Sony ericsson page, its showing the page is under maintenance. Are you guys getting the same response from the sever? Or did Sony completely stop the bootloader unlocking?

Same question here. I tried it since yesterday and that feature is under maintenance till now. I am planning to unlock R800i. Did Sony Ericsson stop the bootloader unlocking and if so, any alternative to unlock bootloader may I know? Thanks in advance.

Well, we will see. Hopefully its just a real maintenance, but maybe they are fixing the hole which the guys used to unlock cdma phones.
Let's hope it comes back to life soon!
Regards

I guess they're fixing CDMA keys hole. Looks like Verizon isn't happy about it.
But I don't understand why it takes so long to modify some small piece of code to disable MEID calculator.

Maybe you DDOSed them too much ?

Thanks guys.

succeeded, but with a little problem. Could any1 pls help me?
i followed Bin4ry's guide [How-to] Root your Play.
On the first try of flashing system with play_modded, i got some error message like android.process.acore & android.process.media has stopped unexpectedly, so I soft reset it to factory setting and flash system again and succeeded, with no error message.
But the problem is after the root process, my phone can't detect 3G network. The service provider I am using has two options, 2G and 3G, and phone can only detect 2G network.
Another problem is that although I can find WiFi networks and connect, WiFi connection is not working anymore (no data send/receive through WiFi).
If any of you know how to fix that 3G network & WiFi missing issues, kindly let me know. Thanks in advance.
One more, my rooted play is now on 3.0.A.2.184 build and when I connect it to computer, PC Companion said found new software update and ask me whether want to update or not. Rooting process will be overwritten and I will need to root it again if I update software (base 3.1.A....something I think) I would like to know.
Thank you again.
Regards,
edit : sorry if this post should be under Q & A section, please let me know and I'll open a new thread

Im assuming you have a r800i? If so, my simple recommendation would be to flash 4. Firmware. Then enter fastboot and flash dooms kernel which will automatically root it for you. Hope this helps.

ႊThank you. Could you please elaborate more as I am new to android, or please let me know the location (in this forum?) where I could get detail instructions, like, where to/how to get flash4.firmware, flash dooms kernel?
Thank you again.
Sorry, I forgot to mention that I've updated to 4.0.A...(i followed the instructions found here, used X10Flash Tool and Xperia_Relock_bootloader.ftf to get bootloader locked, and use PC Companion to update s/w.

For starters unlock ur bootloader again, as you need it to flash the kernel (which in my opinion is worth keeping), then go over to the developers sub forum, download the UK generic 4.0.whatever the rest of the code is firmware, flash it with flashtool, the go to doomlords thread and download his kernel. All instructions you need are in the relevant threads, easy to follow. I would link them, but I'm away from my computer at the moment. And I cant link from my phone. Sorry. Hope all goes well!

Update 1 : May or may not work with C6902. Chances are it won't as the files are for C6903 but it might work if you use the C6902 firmwares

Hi Carbon, I cannot confirm if it give full root access on locked bootloader, however I am now on locked BL (relocked using Flashtool). And it's working as per, well, usual.
As mentioned in OP, I am not a dev nor am I fully aware on how partial root access will be like. At the moment, if you're referring to something like - locked BL not able to install Dual Recovery, it probably is as I'm not able to install any recovery at the moment. Troubleshooting with NUT and with unlocked BL (will update tomorrow on this, it's bed time.)
Edit : Chances are it's partial. Will look into this matter tomorrow. More updates to come tomorrow.

I wanted to know for those with locked bl do they have to unlock then relock boot loader?

This giude explains step by step how to root .290 FW with locked and unlocked Bootloaders and explains how to unlock BL.
It's a pretty good guide!

Apologies but can I know which part is a repost? I mean, I went through these steps personally without following any guides out there. I simply made my own guide as to post in my local forum however, thought it would be great to at least share the method for .290 root, is it wrong to share some info on how to keep/retain root? Also, I am not very sure if I see any guides that gives such information here on xda yet. Krab's rooting guide is for the older firmwares.
I simply used what resources available and give it back to the community. I'm sorry if this upsets you. I'll remove op if you insist that this is a repost.
Hope to hear from you soon.

the files you will need: MUST PATCH FILE.zip
but in the tutorial, you do not explain when to use the patch

I am on 4.3 and I didn't backup my TA so this thread do not help much. Nothing what I already know.

C6903_14.2.A.0.290_Stripped.ftf from installing flashtool stays in a loop and it's not sony's image and restarts again and again.
In the links you put the file is a zip C6903_14.2.A.0.290.patch but *. With flashtool can not flash.
Greetings.

Why are you attacking this guy?!
Oh no, he opened a thread - unlike many other guy who open threads just to say we have new update in update center - this one is really good and smart one.
Of course something will be repeated but this is a guide and NUT has ROM, that's the difference.
I must agree with some comments - XDA for Z1 isn't good, all the time we see bad comments and very little development.
In Xperia S section we had so much fun why can't we have that here?
Atmosphere just isn't right....
For a days I'm trying to force my self to do some theme MODs but if I'll get this kind of "tnx" than I'll keep it for myself.
We have great guys here, awesome MODers and DEVs let's show them a bit of respect and if something they made isn't for you - just skip it, don't spit it.
Moderators are here to say what's junk and what's O.K, I agree with @gregbradley - way toooooo much of "how to" that aren't finished but this guys are trying their best to help you.
So...tnx to @8geek and if someone knows better and can give us full root on 290 - awesome, let us see that...

[FTF] [UK Generic] D6503_17.1.A.2.55_1281-5806-R5A.ftf

this FTF is created from my Phones4u unlocked handset.its UK generic fimware without any bloadware. should work on other unlocked european hanset too. here is the link
https://mega.co.nz/#!txkCQArB!LMVBizNxSHpuqqvgIEPLsQWJPpxvgUXSXr7zYWz8gqw
Here is the quick guide to flash ftf using flash tool.
The first thing that you need to Download last version. Search google for latest version
Step 1 : Download the Flash tool and install it. Open "C:\Flashtool\drivers"
Run the program “Flashtool-drivers” .Check the option “Select components to install” and find the phone for which you want to flash the ftf file In this case Xperia Z2. Select both ”Flashmode drivers” and “Fastboot drivers”. Click the “install” button and wait till drivers are installed on your PC. If you are using window 8.1 64bit, follow this guide to install these drivers
64-Bit editions of Windows require digitally signed drivers. The problem is that many devices ship with unsigned drivers. Today, I'll show you how to install them regardless.
Keep Pressing shift button and select restart.
Once your Computer has rebooted you will need to choose the Troubleshoot option.
Then head into Advanced options.
Then Startup Settings.
Since we are modifying boot time configuration settings, you will need to restart your Computer one last time.
Finally, you will be given a list of startup settings that you can change. The one we are looking for is “Disable driver signature enforcement”. To choose the setting, you will need to press the F7 key.
That’s all there is to it. Your PC will then reboot and you will be able to install unsigned drivers without any error message
Now open ”C:\Flashtool\firmwares”, copy paste the downloaded ftf file specific to your xperia device & latest firmware.
Run FlashTool
Step 2 : Switch off your xperia,wait for 30 seconds, Insert USB Cable in PC first & hold “Volume Down or volume up” button while you insert cable in Xperia phone. Green light in notification LED confirms that phone has been connected successfully.
Step 3 : Notice the “Black Thunder” option in the top most left corner. Click & Choose option “flashmode”.
Click “Select source folder” and select the copied ftf file from “C:\Flashtool\firmwares” and check the option “Wipe Data”. Under option “Misc” , check mark the option “No Final verification” if you are on Android 4.0.4 ICS Stock version.
Click OK, now Flashtool will prepare files for flashing & flash the selected ftf file on your xperia device.
Start the phone once the flashing is done. The first reboot will be very slow. after that.
That's it you are done.

Thanks for posting this its greatly apprecaited

You don't need an unlocked bootloader to flash stock ftf file with flashtool.
This will work fine on any branded set but will replace firmware with generic so no network specific apps (bloatware).

Hi everyone!
Please be kind if this is a stupid question :laugh:
Got my Z2 from vodafone today as they have carrier exclusivity. I know that debranding the phone will do nothing with regards to the SIM lock status of the phone, however I want to get every step out of the way as soon as possible.
Is it okay to flash the firmware BEFORE having received an unlock code and will an unlock code for the network just remain the same or should I wait until the phone is unlocked and then apply the debranding?
Any advice appreciated!
(Also: Has anyone who has flashed noticed speed increases or anything that doesn't work smoothly? It seems only VODAFONE UPDATE is impossible to get rid of and I wonder if it's worth the drama ).
THANKS GUYS!

Copy the system.emmc.win from your TWRP backup folder to the folder containing fastboot on your PC (or any folder, if fastboot is in your PATH). Make sure your Android SDK platform-tools are up to date!!
Reboot the device into Download mode (adb reboot download) and connect to PC.
Fastboot flash the backup file* (fastboot flash system system.emmc.win).
Fastboot flash stock recovery (fastboot flash recovery recovery_signed.img)
Reboot to system, install OTA.

There was another link in comment section referring the same problem. That link said something about unlocking bootloader of 'untouched phone'. After the first command of that link, the response is '(waiting for device)' . There is no other response. Please help me root my phone. It is much appreciated if you guys give me step wise process (along with respective download links). I am a first timer.

If MIUI doesn't come pre rooted you can do it with supersu. The all in one tool isn't designed to root roms. It is for unlocking the bootloader and install custom recovery in first.
As you have already MIUI installed, then you have already unlocked your bootloader, installed a custom recovery and a custom rom.
Do you really know what "rooting" means? It's only giving more user privileges over the standard ones to obtain deeper access to the system to modify things for example.

1st before all: read again the pros and cons of unlocking bootloader and read the instructions twice before doing anything. Your alone responsible for your doing!
1st: you have Cyanogen OS 12.1 installed, that's not the same as cyanogenmod. That's just for information
2nd You don't understand what rooting means. Please read again.
3rd Yes you can follow the steps from the link until step 6. After that you can flash a custom rom which is in most cases rooted.
