[Q] Bootloader unlock and Omnius problem

Hi
today i sim-unlocked my Xperia X8 using Omnius, but now i want to unlock the bootloader to install a different kernel from the stock kernel.
Following the instructions below http://forum.xda-developers.com/showthread.php?t=1254225, when i start the file msm7227_omniusSL.cmd i get this:
------

but than if i verify with s1tool, i get the message (RUNNING S1_EROM VER" R8A029 ") and so bootloader has not been unlocked.
Does anyone know a solution?
I used Omnius for SE v0.27
Thanks a lot

I have the same problem ...

me too...any news?

Same for me!
Any of you with original 2.1??? Maybe it only works on original 2.1, I remember that I had to change from rom to original 2.1 so I could unlock with Omnius.

I tried with the original 2.1 and with other 2.2/2.3 but it's the same

Hi,
I have been making some experiences and I think that all of us want to unlock boot loader to be able to change kernel.
So it's true that using the omnius method it doesn't work but if we use semc method it works, but we loose radio.
So my idea was:
1- Unlock with SEMC method
2- Apply custom kernel
3- Unlock with Omnius method (this will relock bootloader but recover radio)
I have tried 1 and 3 and worked, I'm just affraid that also doing nº2 might bring some problems, what's your opinion?
Found my answer!-""If you relock your bootloader while using a custom kernel your phone will be bricked!""

Somebody already unlocked bootloader anyone of you?

I have searched I never found anyone that sim-unlocked with omnius and then unlocked bootloader

I just found out this myself. After wasting $100 (Sale Price) for the omnius unlocker. They never stated anywhere that it would relock bootloader, nor did they mention it could be unlocked. After an inquiry, I was told that msm7227_OmniusSL.cmd should help me...? So I am off on another research adventure. Not to mention I cannot even get my phone to "register on the network". Anyone want a Omnius License with 11months and 2weeks with 4 x10 unlock credits? I take paypal! I just knew I should have ordered the sekey and waited a month for it to arrive from hong kong. I truly feel like I got the "Royal Shaft!".
Can anyone help?

@unimatrix725 if you made a backup of your TA, then you could restore your TA as it was before you unlocked with omnius, so you can unlock your bootloader, the only downside is that your phone will be sim-locked once again, oh and watch out, because you can only restore TA with an active omnius account, i.e. have a 1 day/month/year account, so if you want to restore your TA you should do it before selling your credits
i hate that the only safe way to have both bootloader and sim unlocked is with setools, because the credits i dont mind, but the activation fee is too much price for unlocking one phone

well,for our x8 device,we can actually unlock bootloader using flashtool(latest one)
here a complete tutorial with picture that i manage to safe as pdf file(for my future use) and i think it might help,but it actually from x10 forum,however i already test it myself,and work it for our x8,to unlock the bootloader,follow this step carefully
press thanks if i help

he he he, sorry i think i misspoke that, what i meant was have unlocked sim with setools and unlock bootloader with any other method, not necessary both with setools , if someone could fix the my7227bootwrite_omniusSL so everyone that unlocked their sim with omnius could unlock the bootloader would be great, but i haven't seen any dev interested in helping us ...

OK EVERYONE HAVING THE SAME PROBLEM HERE IS HOW TO FIX IT!! After network unlocking your phone with Omnius and you then want to unlock the bootloader follow this tutorial: http://forum.xda-developers.com/showthread.php?t=1254225. You will be using tool msm7227_setool2.cmd to unlock your bootloader. When you have unlock the bootloader install a custom kernel then install your custom rom I suggest GingerDx. (I am not going to get into how to flash a custom kernel or roms there is loads of threads to help you with that). You will notice the network does not work (no coverage). Download the stock kernel from the link above. Flash the stock kernel then use msm7227_OmniusSL.cmd to lock your bootloader. This may take a few times and a bit of patience before the bootloader locks. Now you will have coverage and be able to use any sim card in your phone. Custom kernels dont work after using omnius network unlock tool. It always ends up with no coverage. So just stay on stock kernel. If you need to update your rom you will have to go through the whole method again. I have attached the bootloader unlocking/relocking tools below

I want to try this, but I've a dumb question... why do I need to install the custom kernel and then the stock one? .... why not just flash the rom alone?

go ahead with dual recovery. it won't brick your phone.
locked means it can be installed in locked bootloader.
unlocking bootloader lets you install custom roms like cyanogenmod, omnirom etc which are close to stock android something like in nexus devices.

[Help][Q] Keep getting bootloop after UB

okaay so i rooted my phone again and decided to unlock my bootloader, i have verified that i am able to unlock my bootloader and follow all the instructions on the official sony website on how to unlock the bootloader. i get no errors during the cmd process either, i turn my phone on and it gets to the purple boot animation screen and then freezes. Is there anyway around this ?
EDIT: Also i used DooMlords thread and get the same problem? /: - I also use Flashtool but when i press 'blu' i only have the option to RELOCK my bootloader? :S

Anyone ? /: been looking for the solution all day

Just flash any desired custom form via fastboot and that's all, it should work.
When I unlocked my bootloader with stock firmware it doesn't boot anymore either, so I had to flash any other or reflash it again

Just flash a official FTF, then go to service menu, tests -> configuration and if your bootloader status is:
Unlock allowed: Yes - you can unlock your bootloader
Unlock allowed: No - your bootloader is hard bricked and there's no way to solve this (permanently)
Unlocked - congratulations.
I suppose your bootloader is hardlocked. check for yourself and if anything changes - quote

it says ---> Bootloader Unlocked: Yes. But iv'e tried to multiple times and still get stuck at the animation screen on boot up

If you are on a custom rom you just have to flash the custom kernel over it putting the phone in fastboot . No need to unlock bootloader again. Please ensure that the rom supports the custom kernel or there can be bootloops .

I have tried unlocking it with and without a custom ROM on my phone, it says 'Bootloader Unlocked: Yes' on the service info and i also only have the option to RELOCK my bootloader when i try it on the flash tool. Does this mean that it may actually be unlocked already?
EDIT: im also using This custom ROM which has custom kernals to select from
-Thanks

The rom that you gave link to is a stock firmware based custom rom, so it will have stock kernel.
I think it must be written Bootloader unlock allowed: Yes, on your phone
You will need to unlock the bootloader, PM me I will guide you how to do it.

ok this might be a bit too many questions

hi all,
i have recently aquired Sony Xperie SP C5303, and i now i'm lost since i never had android phone. all i used was various emulators for PC and stuff...
but now there is many stuff to be noisy about. and probably this has been answered many times but please, do me a favor and pretty please answer again if possible.
1. Phone is SIM locked (i'm working on getting unlock code from provider, since i have right to do so, after contract expires..which has)..but is there any way to unlock phone before i get the code? i'm wondering how technitians in local services do that. they ask about 30€ for unlocking device, and i doubt they have acces to provider's unlock code.
2. I tried to flash phone with custom firmware (using flashtool) but it failed on me even though i used right firmware, and phone bricked. however i managed to recover phone with sony PC companion and it now works same as when i got it. Firmware 12. 1. A. 1. 205, android version 4.3. i have no idea why it failed on me during flash. can it be cause phone is no rooted, and have no root support? (whill connect to this on 3.) do i have to root phone before flashing? i would really like to have root access.
3. i was unable to do hard reset of phone with power + volume down button. or any other trick didn't work. i couldn't not enter android recovery options. i followed instruction on how to root my phone on
Code:
developersonymobile(dotcom)/unlockbootloader/unlock-yourboot-loader/
. i entered
Code:
*#*#7378423#*#*
to check if my device is unlockable, it says boot loader unlock allowed : No. Does this mean i won't be able to have root acces on my phone? or i still have to learn difference between terms or what they mean.
also is that really true what they warn about that there is no turning back after i root phone and all. won't just hard reseting phone or repair device with all defaults troubh pc sofware bring back and vipe everything back? how will than service know if phone has been rooted ever?
thank you in advance for all your answers.

"Bootloader unlock allowed : No" <= this means you can't use UBL ROMs or custom kernels.
You can always root and use LBL ROMs though. There are plenty of LBL ROMs out there to try.
You can always un-root your phone. And you can always repair your phone's OS by flashing the Stock ROM via flashtool. Doing so would remove root access as well, no one would know you ever rooted.
Root using towelroot.
Get recoveries by Dssmex.
Then flash LBL ROMs, mods, ports etc. that you want.
and Be careful when you flash anything,
Read the threads, don't try to flash any UBL ROM as it may brick your device.

First thank you for helping.
UBL is unlocked boot loader right? and L is locked. sorry to doubt your last tip but i need to double check was it typo or...? you said don't flash UBL. isnt that supposed to say don't flash LBL. or i have totally got this wrong. maybe i don't know what what's LBL and UBL.
but just to be safe? where can i find stock ROM? i tried official site, they don't let me download firmware manualy. only trough sony PC companion automatic repiar. Which is ok too i guess. else i can download sony flash tool callsed emma, but i cannot get login info since they need about 7 days to approve my registration.
so my first step is to root my phone. ok i will do that. i might do it manualy, not trough application though.
what about sim lock? after i root phone, is there sim unlock command or what? and do i need code...how do you unlock your phone to be able to use other SIM.

Welcome.
And no, I did mean "Don't flash UBL ROMs"
UBL = Unlocked Bootloader
LBL = Locked Bootloader
The ROMs that are made for Unlocked Bootloaders are UBL ROMs.
Unlocked Bootloader users can use both LBL and UBL ROMs.
But since your device's Bootloader cannot be unlocked, you can only use LBL ROMs.
It's written in almost all ROM threads if it's a LBL or an UBL ROM. But if it isn't specified, then be sure it's UBL. (Like all 5.1 ROMs are for UBL)
Download stock ftf from here.
Use Flashtool v0.9.18.5
and I can't say about the last one as I don't use a carrier locked device.
Try and see what happens.

thank you again for reply. you've been very helpfull with all info.

that is exactly from where i got it the first time. also same flashtool version. after i tried to use that firmware, my phone bricked.
even though it's stock ROM, probably cause my phone had locked bootloader (i finally found article on what is bootloader and i got it now).
but after this, i have used sony software to recover my phone and it works again.
now important stuff. so my device's bootloader cannot be unlocked. does that 100% means that i'm stuck with locked bootloader and no way of getting it unlocked.
even on sony offical site there is process tutorial how to unlock bootloader, and it says "if you device isn't listed, than you cannot unlock bootloader".
but it IS listed and I AM able to get the unlock code for it. now i'm confused. can i still do the process showed?
another confusing thing is where i read about bootloader, it says that for to be able to root i need to flash custom ROM, and to do that i need to unlock bootloader.
but you have provided link for "towelroot" which was able to get my phone root acces. is it different from rooting my phone manualy after unlocking bootloader. how did it manage to root it anyway? and with towelroot it still has bootloader locked. actually it says "boot loader unlock allowed: NO!". now begs the question does that mean, not allowed, but i can be unobidient one and still unlock it without clearance, or does it mean .."you're stuck with locked bootloader. deal with it!. if you try to unlock bootloader your phone will brick"!.
i think after i get answer to this, than it would be my last question for this topic
also again, thank you for answering all previous questions...and this one, hopefully

Did you install the drivers properly (Flashmode, fastboot, viskan common) ?
You need to disable driver signature verification before installing drivers if you're on Win 8/8.1/probably 10 too.
And flashtool should work perfectly in both LBL and UBL phones.
You said your service menu says, "Bootloader unlock allowed : No"
Even if you get a BL unlock code you can't unlock it coz it's not allowed.
And by messing with the bootloader or trying to flash UBL ROMs may permanently brick your phone.
And different phones have different rooting processses. Rooting our SP is easier than most other phones by TowelRoot.
And "Bootloader unlock allowed : No" is more like a "You're stuck with locked bootloader. deal with it!. If you try to unlock bootloader your phone will brick!".
And you can still use a lot of LBL ROMs, from 4.3 to 5.0. So don't worry Lol.
Welcome

i did install fastboot and drivers and everything acording to tutorial. i payed attention on par "pay attention to this. be sure to install drivers correctly, lol"
i'm using win 7 64bit sp1. i have disabled UAC. i'm alaways running as admin. as for flashtool. software works perfectly..it just fail flashing.
it goes to part where i need to unplug phone and plug in holding volume something button..it says on poppup. than i plug in phone and it starts flasshing..it goes up to 40% something percent. if finish few files but when it comes to system.(something) i forgot extension, it says failed. flasshing stopped. than after that i can't turn on phone again.
i couldn't untill i recovered via Sony PC companion. i did try to flash it several times with several roms. i think it's cause my provider messed with bootloader. they locked it together with sim. on official sony site. it says:
"Note! Even if your device is listed here, certain releases of the device model may not be supported due to operator restrictions. Please select your device on the Start tab to check if your particular device can be unlocked."
anyway, i even got my provider's firmware trough flashtool download system, got my provider's name and exact same firmware that was installed. it still failed on same file.
than after i recovered i didn't try to flash anymore. i don't even know what's the point, if i can have root access without it.
i'm not so keen on installing other android version, unless this one gives me problem. for that i need to unlcok phone first to be able to even use it or test it so far it's has been t urned off most of the time

I see.. I'm not actually sure why Flashtool isn't working.
Anyways some good 4.4.4 LBL ROMs are 'CM11 by Bagyusz', 'Omni-X by NeildownX', PA etc.
Try them if you want.

Anyways some good 4.4.4 LBL ROMs are 'CM11 by Bagyusz', 'Omni-X by NeildownX', PA etc.
Try them if you want.

I assume you're now on a rooted stock ROM.
Follow this to get recoveries.
Reboot, when you see the Blue LED burn, press vol down to enter TWRP recovery.

can i use cm-11-20150822-UNOFFICIAL with flashtool so i avoid installing recoveris or CWMP?
flashtool worked for me it just gave me an error during flashing one of the files....that might be cause i didn't know difference between LBL roms and UBL roms. maybe problem was incorrect rom type for my phone.
i tried to install recovery tools. and i had some problems...when i swhitched on phone there was no light showdown,,just red led...and after phone entered safe mode. but not in recovery menu.
i sure have no idea what to do...now everything is so strange.
to be honest i'm considering dropping this whole thig of and use stock rom as it is...
it would be cool if there would be automatic debloat application which will remove all bloatware...
or at least bloatware list of apps i can delete manually, without loosing important function on my phone. than i would not need custom rom!

If you're on CM11 by Bagyusz, Open Terminal Emulator and enter the following codes,
su
./system/bin/recovery.sh
^ it will give you access to recovery when you see the red LED while booting.
If you decide to go back to stock, you can freeze/remove these apps.
I made the list when I was on stock. Take a backup before removing them just to be safe.

thank you a lot! this has all been so helpful!

CANNOT UNLOCK BOOTLOADER please help

hey i cannot unlockbootloader in service info bootloader not allowed which frimeware i can unlock bootloader?

hi there,
if the phone says in the service menu bootloader unlock allowed no means it cant be unlocked but that means you can still install a custom rom which should say LBL rom. Follow this guide: http://forum.xda-developers.com/xperia-sp/general/guide-flashing-custom-roms-ultimate-xsp-t2888579

Go to Xperia website, and search Unlock Bootloader, there you can select Xperia SP and see the number code type it on your cell phone to see if your cell can unlock the bootloader ( My English is more less bad, sorry for this I am Brazilian )

If it says "no." you can't unlock it. You can install custom ROMs as long they are stated that are for Locked Bootloders. Do not attempt to flash a ULB ROM onto a Xperia SP with a LBL because it will soft brick your phone. Attempting to unlock the bootloader when the the status says "no" it's not recommendable and could hard brick your phone.

As mentioned above, if the phone says "no" or doesn't say anything at "bootloader unlock allowed:" thing, then there's no way around that. You can still get custom roms though. There are some roms that will work with locked bootloaders.
Pro tip: Always buy generic phones if you want the best from xda. Always check what you're going to buy.
