Bypass bootloader and install custom kernel?? - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

I still remember when I own a xperia x10 all the devs there use a method to bypass bootloader and install custom kernel..can it work on xperia mini pro since I cannot unlock bootloader cuz fastboot is disabled and I really want to flash jelly bean rom on my phone but without custom kernel it is useless...please give suggestions..
cheers,

well you have to wait for jb rom for locked bootloader if you flash rom without flashing kernel it will cause boot loop.

1) yes you can root locked bootloader
2)installing recovery is not possible and still in experimental stage on U so may be it can be done for Sola too
3)No custom roms for bootloader

[Q] need firmware .587

Hi, I know the update 4.1.b.0.587 it's out, and I want to update my mini pro, but I'm stuck on .431 so anybody knows how can I update my SK17A because I tried with SEUS, and it says I already have the last update, PC companion say's the same thing, so if someone could help me that will be perfect..I have the mini pro SK17A not the SK17I
At the moment,4.1.b.0.587 is out only for Sk17i i guess.
Sk17a is till .431 as of now.
Have you seen someone using an sk17a with .587?

not really, but i dind't know that the sk17i was that different from the sk17a that's to bad, but i guess i should wait then
i guess i'm gonna forget about that update for know, so i have another question, and i hope someone could help me..as i have an stock rom, android 4.0.4, with stock kernel, compilation .431, no root, no unlocked bootloader, no nothing actually xD so my question is, my phone with ICS is a little slow, mostly on games, and i would like to know is what i need to do to solve that? i read on other threads that flashing a different kernel can fix that, it's that true? and besides, can i flash an custom kernel having an stock rom? how can i do that? i guess i need root on my phone first, i can do that, but i need to unlock the bootloader? that i don't want to do it
a stands for america!
And i is the international version!
That's what ive heard!
Idk what the differences are though

Yes custom rom/kernel will make ur phone smooth in every way. But for trying custom kernel u need boot loader unlocked.But u can try custom rom without unlocking boot loader if u have rooted :good:

Thanks! But i was talking about having stock rom with custom kernel, or do i need both for make it work better?..besides, the reason i haven't rooted my phone and unlocked the bootloader is becauses is to hard! XD i remember when i used to have a motorola milestone, you just need to install the app universal androot, or use superone click, and that's it, you have your phone rooted, but know it's to difficult, i have a galaxy nexus too, i recently root that one, and it wasn't easy either but i did it, but with this one, the xperia mini, it looks like having root and unlock the bootloader it's no for everyone
After rooting,when I'm on cyanogenmod9 on ics,I can overclock to 1.6 ghz too while gaming.no lag in using phone too.though my bootloader is unlocked. I would suggest you to root for a better experience!
Cheers.

U must unlock bootloader to use custom kernel even u use with stock rom.just unlock ur bootloader its not that tough.the easiest way to root after that just flash a custom kernel which is pre-rooted( like rage kernel & many) via flashtool.u will have root access

To flash custom kernel you need unlocked bootloader, but for flashing custom ROM you need root and/or unlocked bootloader. Mostly of the ROMs work on locked bootloader too but if you want to play games so much you should Install Pure AOSP/AOKP based ROM and if you want best experience with games you should also install custom kernel.

AW: [Q] Unlocking BootLoder Failed Xperia neo
Than you are allowed to unlock your boot loader. This doesn't mean that it is already unlocked.
I unlocked my boot loader via test point and rooting status still says unlocked allowed.
Best way to test is flashing a custom kernel.
Choose a kernel compatible to your current android version. ICS kernel for ICS android and GB kernel for GB android.
Take a look at the stickys. You will find a description how to flash a kernel and which kernel is for which android version.
Good luck.

Thank u very much. I am now on 4.0.2.A.0.62 rm and I am going to old 4.0.2.....42 to unlock bootloder and root. Will it done the trick for me?
is karnel included in rom (.ftf)?
I am new here. So please excuse my false and poor english
Whatever motorazr said is absolutely correct.. just flash a custom kernel and if it gets flashed that means your bootloader is unlocked.. If it dosnt then unlock your bootloader officially.. Its given on sony's side about unlocking.. Check it..
And if you are flashing .ftf file it will change your firmware totally.. Custom kernel is different.. Stock. Ftf files are different.. Go to sticky thread in neo v development section, for tutorial about flashing kernel..
Hope this meets your need..

AW: [Q] Unlocking BootLoder Failed Xperia neo
If you really flashed night elf kernel than your boot loader is unlocked!
What program did you use, flash tool?
Give us a log cat from kernel flash that we can take a look. Or make a screenshot from your phone settings showing android version and kernel version.
Look at my screeny.
No need to root your phone with doomlords method. Almost every custom kernel comes prerooted and has build in cwm. Just flashing a custom kernel and you have got superuser access and cwm.
You can try cm10 with your unlocked bootloader. Just flash a compatible kernel and install rom via cwm.

I think your Bootloader is not unlocked...
Please unlock it first...either with official or unofficial way...

Yes your boot loader is unlocked!
Did you do it yourself?
Anyway your phone is free! You can try anything you want!
For cm10, download latest nightly for your phone. Haida for neo v and hallon for neo. The download contains a jb kernel for your phone. Flash it. After that enter cwm and install the rom. Last step is flashing Google apps for jb via cwm. After all that you are done and can enjoy android 4.1.2.

Just to clear something out I tell you my personal story.
I had a live with walkman which I unlocked official. The rooting status in service menu changed from boot loader unlock allowed: yes to boot loader unlocked.
Actually I have got a neo v. I unlocked the boot loader via test point. Guess what happened? Rooting status in service menu still says boot loader unlock allowed: yes.
At the moment I haven't got a stock rom installed so I can't take a screen. I have posted some earlier, I will search for it and post it here again.
I don't know if it is possible to edited a kernels name easily. The screen he provided shows that his current kernel is named night elf.
Stock kernels are named different, I don't remember correct but wasn't it something like performance?
Best way to prove us is to provide a flash tool log cat showing a successfully kernel flash.
Again I ask the op: have you unlocked your phone yourself and which method did you use?
Or have you bought the phone second hand and somebody had unlocked it already?

Well you've a point there mate
I think in that case,he unlocked unofficially ie by Testpoint method!
I thought he used official method

[Q]FTF Kernel for Mini Pro

Hi everyone, i just want to know if there are a software to convert img kernels to ftf kernels or if ftf kernels for Xperia mini pro exist, this question is because if so then we could flash any rom regardless bootloader status on our device and everyone with locked bootloader would enjoy benefits of O.C and Cool Custom ROMS just like xperia play does with its ftf kernels.
Thank you in advance.:fingers-crossed:

You got it all wrong. The only way to Flash a Custom Kernel is to Unlock your Bootloader first. The reason I converted .img files into .ftf files is so that people that unlocked their Bootloader via the Test Point Method and had "Bootloader Unlock Allowed: No" would be able to flash Custom Kernels, because in this scenario they would not get access to Fast boot Mode but will be able to flash Unofficial Firmware via FlashTool.
I do not have the Xperia Mini Pro, so if anyone wants to test a FTF kernel for it here it is:
[SK17][Kernel][FTF]nAa-3.4.45-V03[JB]

did you convert it or did you find it somewhere, if you convert it would you tell me how you did it?, and thank you for your work converting img to ftf for xperia because thanks to you i'm using Xperia Play Z by Mark, i tried to convert his kernel but it does not work to me (it gave me bootloop) but with his kernel converted by you i finally did it.

I Converted it. I used the same method that's for the Xperia Play. That is why i want some one to test if it works.
EDIT:
I'll just reply here and not your PM
I tried it today and it does not work, :crying: for one moment i thought it will flash but no, i was excited with the idea to have custom kernel in locked BL sk17.
Thankyou anyway.

I don't think you understand the purpose of Kernels converted to FTF files. First of all Unlocking the Bootloader on any phone isn't exactlly the ability to use Fast Boot Mode but the ability to flash Unofficial Kernels(Custom Kernels),independently of being it done either with Fast Boot Mode or Flash Mode. So by Unlocking the Bootloader of a Xperia Play(Using the Test Point Method) with "Bootloader Unlock Allowed: No" you get the ability to Flash Unofficial Kernels(Custom Kernel) but not the ability to use Fast Boot Mode, and so the need of Flashing a Custom Kernel via another method arises and that's where Converting Kernels into FTF files and Flashing them via Flash Mode comes into place.
Now, I am not a Developer nor an Expert in hardware, but in theory this method should at list work on all 2011 Xperia Phones. If you would be willing to try this on your Xperia Mini Pro and it ended up working. This could help a lot of people(with "Bootloader Unlock Allowed: No") not only the Xperia Mini Pro but all the 2011 Xperia Phones.
So if you want to help, try Unlocking your Bootloader using the Test Point Method. I also want to say that this could be risky since it only has been tested on the Xperia Play.

I tried it doing test point before flash it in flashmode with flashtool, you know, first test point->patch semcboot->flash ftf with flashtool in flashmode. I saw in a post a method to "be able to use" fastboot on sk17, since is my mother in law's phone this method is not suitable, so i'll try with your ftf but not in near future, maybe when i get one sk17 just for me. Talvez en las chacharas.
Bump
Does it work?
