[Q] Flashing Kernel

Can I flash a kernel on my mobilephone (r800a) rooted/locked bootloader? Is there any other way that I can do it? (Cannot unlock bootloader btw)

You can't. You need an unlocked bootloader for that.

Unless your bootloader is unlocked you CAN'T get into fastboot.
You will only get into flash mode.

The only way is with a kexec (boot with stock so it bypass security and then load cyanogen mod kernel) as i come from xperia u and they have tryed the old 2011 way with the pins and that has been blocked.
They have tried to force change it in the .ta and all they did was brick phones.

someone has to port this to your device and find some free memory on boot and you can boot anything on locked bootloader.

Can't unlock boot loader or flash stock

Hi there,
Has anyone got a way out of this.....
I have a rooted C1905 that I have been playing around with. I want to try CM11 but boot loader unlock fails with a "FAILED (unknown status code)" report after I send my unlock code. I then thought I'd flash back to stock using S.U.S. but that fails too saying that I have a customized rom... which I don't!!! I seem to be stuck! is there anyway to force a stock flash?
Cheers

Have you checked if your bootloader can be unlocked? Go to the dialer, type *#*#7378423#*#* then go to Service info => Configuration. In rooting status, it should say "Bootloader unlock allowed: yes", otherwise it won't work. About your flashing problem, try connecting the phone directly in flash mode before opening SUS, by turning off your phone, holding Volume Down and plugging USB cable or by flashing a FTF file through Flash Tool...

It happened to me also ,check your IMEI CODE,you need to send first 14 digits of your IMEI,

Flashed an FTF of the latest but still can't unlock the bootloader. still get "unknown Error" and it wipes my apps.
Also can't use "repair my phone" on PCC as it says I have a Customised Rom, could this be due to me trying tools like flashgordon and debloat/deoxing flashing or routing? if so how can I get back to a stock state for a UK XM so I can start again?

Nope, but try this anyway.
1. Disconnect your phone and turn it off but keep the cable attached
2. Open PCC and go to Update
3. When it says no device found click the blue repair link
4. Choose Xperia M when asked to
5. Follow the instructions
I have a locked bootloader and modified ROM and it works flawlessly. Keep us updated

Hi there,
Thanks for the help, unfortunately it doesn't work! PCC recognises my phone ok so I carried on to the "repair my phone" tab.
and this is what I get after it's downloaded the firmware and tries to flash it...

You can flash without locking also. And did you take ta partition backup to lock again?

Hello Kaml,
Im not sure if rooting "by unlcking bootloader" is the only option you are considering but you dont need to unlock bootloader to root 4.3.
I rooted my Xperia on 4.3 following this thread: http://forum.xda-developers.com/showthread.php?p=51730927
If you want to unlock bootloader anyway, please, make a backup of the TA partition first: http://forum.xda-developers.com/showthread.php?t=2292598

Rooting with locked bl is too complex i didnt get it clearly and didn't used these tools before :/
Can someone please explain it to me clearly what to do
Sent from my C1904 using XDA Premium 4 mobile app

Hi Kaml.
Yeah, it's a bit confusing when you first go to it. If you dont like the adrenaline/fear/expectation mix, better is to ask someone else to do it for you
You say that's too complicated to root with a locked bootloader. That’s not always true, it’s relative. The post I linked to you is very clear and it’s not complicated at all, but you will need to start from a 4.2.2 rooted ROM, maybe that’s the complicated part for you.
Anyway, I suggest you to confirm if you can unlock your bootloader. Did you checked it already? It may save you time by knowing it beforehand.
To check, go to the dialer and type: *#*#7378423#*#* then go for Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you are able to unlock it. This is from thread http://forum.xda-developers.com/showthread.php?t=2484622
Read that thread, especially when it says “before unlocking please take backup TA partition from here”. By backing up the TA partition you can restore it later if need and then you have some chance of not losing Sony warranty if you ever need it.
Im not aware of other methods for rooting 4.3 besides the link I posted on my first reply, take a look and you will find other methods (probably).
Anyway, if you are interested in backing up the TA partition, it’s only possible if you have a rooted phone already and that’s kinda of a chicken/egg problem so that’s another motive of seeking for rooting methods without touching the bootloader at first. One way to solve it is to half root your phone, enable USB debugging and Unknown Sources from development menu, then run the script to backup the TA partition.
