[Q] Sony Xperia U st25i fastboot mode / Bootloader unlock allowed: NO - General Topics

Hi.
I need help.
In 2012 I bought a Sony Xperia U st25i, and as you know officially can't update it to Android KitKat.
So I read a lot of forums and one point I stuck, I can't get to fastboot mode.
I rooted it, got Superuser on it, got clockworkmod etc. I've tried everything, but I can't get to fastboot mode.
Is there a solution to unlock it, if it says; Bootloader unlock allowed: NO?
Thanks for your help.
PS: sorry if my english is wrong

follow the instructions on this article dude, everything is here: http://forum.xda-developers.com/wiki/Sony_Xperia_U
i have a sola but it has the same everything hardware wise

If you have locked bootloader (and you have) you can get only room based on your kernel. So sorry but forget about KitKat and everything more than your stock (4.0.3).

First root your phone then unlock bootloader by that solution.
But unlock bootloader will lose DRM keys permanent, Bravia Engine (not sure Xperia™ J have or not)
I recommend you to backup the DRM keys first (search how to backup the keys)
And after that just follow the instruction to install CM10.
Last you can back your phone to normal but you will lose DRM keys.(you can restore if you have backup)

So i rooted my device with this method, http://forum.xda-developers.com/showthread.php?t=2327472, this also instaled SuperSU.
Now following the instructions on sony website to unlock bootloader it says
First, 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. If you have a tablet, click here to learn how access the service menu.
In your device, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.

Unlock bootloader: no. There is no workaround / tespoint method yet. You can only root and use roms for locked bootloader. Cm10 needs unlocked bootloader.

my Xperia L C2104 device does not show any YES or NO in the bootloader unlock allowed section of service configuration.

and no yes or no after that.

or is there any other method using flashtool. plz convey tht method if any.

The phone doesn't need to only show YES or NOT.
It can also be ALLOWED or NOT ALLOWED.... which is practictly the same thing dont you think?
For sony devices bootloader can only be unlocked this way

I also tried that method a month ago. I will try it again. but the commands given in the website arent accepted. they show error with tht commands. :crying:
I had tons of problems with this, I thought all was lost. I have win 8.1 x64 and assumed it was a driver problem and so did the unsigned driver install in windows safe mode. No dice, flashtool continued to be unable to unlock. What worked for me was re-submitting my code to sony, I got a totally different unlock code and then it worked through flashtool! Maybe give that a try? Fingers crossed!!

[Q] Unlocking bootloader XE SS

hey guys, I've noticed that almost all of you have the bootloader of your Sony Xperia E JB (C1505) unlocked.
Mine says not allowed, I just wanted to ask if you guys that have it unlocked, had the same ''status'' as mine, or if there is any way that I can unlock my bootloader...
I have my phone rooted but with the bootloader unlocked the possibilities are not comparable
I really wanted to change the rom, my kernel (to be able to overclok etc), but im afraid I can't to that
Please give me an answer

To unlock bootloader follow the instructions from Sony Mobile: developer.sonymobile.com/unlockbootloader
I had to send my mobile to Sony service center to change the Rooting Status: Bootloader unlock allowed: No to Yes.
Good luck.

Complete Guide for Xperia E1 (rooting, recovery, flashing, bootloader)

Xperia E1 has his own Subforum now, Thank you XDA!
If any moderator sees this, please close this thread!
Hello there!
First of all really thank you for making this topic, it will really help people who wants to customize their Xperia E1.
I really appreciate your action.
Secondly, I wanted to ask more help with the bootloader unlock.
I do exactly what you do but it always comes the following result;
First, when I click on unlock it gives me Failed error.
When I click on unlock for second time, it gives me Okay, meaning that successfully unlocked.
After, I'm booting into system but it stack at the boot animation.
Some people called this bootloop but I don't know what to do to fix it.
Flashing again a stock firmware fixes this but no unlocked bootloader at all.
Repeating this will give the same results.
I would like some help on it, I remember somehow I had successfully unlock the bootloader without stack at boot animation.
At service menu was saying boot loader unlock: Yes
Instead of bootloader unlock allowed: Yes
I'm able to give any information about my phone so we can fix the problems, I'm not going to buy another phone anyways

You are supposed to VOLUME DOWN + CONNECT USING USB and you should NOT hold the power button.

I have the same problem. Your career force-locked the phone, meaning that you cannot unlock it normally, only temporarily (that means when you do it the second time it says OKAY but when you reboot the device its gonna be locked again)
I got an email from my career, and they say the reason why I cannot unlock it is because of the firmware. I'm starting to think they don't know a thing about bootloaders.
God..So we will never unlock the bootloader of force locked E1 devices?
Edit: I read that force locked bootloaders come with the message at service menu:
Bootloader Unlock Allowed: No
My phone says:
Bootloader Unlock Allowed: Yes
Any ideas? Am I wrong?

Some careers (like mine, Orange) trick the user, they say Unlock Allowed: Yes. It's actually kinda true, because you can temporarily unlock it, but thinking about it our situation is the same as if that message would say No. If there would be test points on the E1 maybe we could unlock it like the older devices, but I'm not sure as it's quite old. Maybe if someone can make a hack to set the flag of locking to unlocked or make a 2ndinit ability to load a second kernel on the bootup process.
I think it would be possible, but it would require a lot of work and a large knowledge of our device (in a deeper meaning)
My phone says:
Bootloader unlock allowed: No.
So i can't unlock?
What should i do if i stuck on bootloop with unlocked bootloader, for some reason?
Need tutorial for this..
Thanks.

You need to reflash the firmware. Kizoky will sure add that later on.

If you brick your phone, you can always reflash the Firmware, or use the backup method which is found in PhilZ recovery.
I'll do a tutorial on this too soon
So..uhm.. Any chance I can root my phone without bricking it with this bootloader stuff ?
Was rooted using Kingo, latest update (20.A.1.2.14) removed root, prevents kingo and all other apps from rooting again.

As far as I know if it's says Allowed: Yes, as long as you obtain to code to unlock, along with using xperia flasher or fastboot tools to correctly unlock then it's should stay unlocked. An unlock allowed: No should not allow a request for unlock code via sony developer world site.

I made a backup zip, that way if you use fastboot tools to flash the boot.img, then the kernel has the philz recovery 6 that can install the clone rom.zip file.

Some careers like Orange in Slovakia trick the user(or use a different force method) that the bootloader can be unlocked by saying Yes in the service menu, but cannot unlock with the Sony Bootloader Unlock code, due to Command did not succeed error. I think they either have a custom code, or as they said in the email I sent to them: we have something Orange(or other career-related) firmware on our device that blocks unlocking. Or maybe it's just a 0-1 flag. (like ForceLockUnlock=1)
How unhelpful of them, that's why I started obtaining off network handsets from 2010 on wards. SIM UNLOCKED ? and fully bootloader unlockable.

I think there's some kind of a 'flag' or something in the TA that blocks us. Or maybe it's something /dev related. If the test point unlocking would work, I would be very happy. Though I don't think it would work with newer phones and it's old.

Well I have three xperia E1's that I obtained off network along with this E3 that are all sim unlocked and fully bootloader unlockable. All the E1's are rooted with jelly bean or kit kat flashed via xperia flasher, with bootloader unlock: Yes. I find the 4.3 jb build to be the most responsive for D2005 handsets.

Jelly Bean for the Xperia E1 (the official Sony one) is way too much unstable. KitKat is more stable. I've had random reboot issues and freezing issues (especially when playing games) on JB, while everything is much better on KitKat (there are still some lags and it takes some time to boot up but everything else is fine.)
The only thing I loved about the JB build was the Notification Shade and the fast bootup time.

You can decrease the boot time, If you delete the unnecessary apps (Google+, Google Books, etc..) And the apps you can't delete, or you are afraid, you can just disable them.

Well I rarely play games on any of my devices, however you are correct in that Jb does reboot more than kitkat does. When trying to control the kernel better for jelly bean, I did encounter freezing, however once I got the correct configuration it was fine.

I would love to say everything is better, however rooting is more of a challenge for some of the kitkat builds and installation of supersu was more tricky/ time consuming. Have to delete apks to speed up kitkat too.
Hope we do get a stable lollipop ROM for the E1.
