Hi there,
I managed to root my Xperia Z1 using firmware 14.2.A.1.136 with the help of DoomLoord´s stock kernel FW-136_v01.
Upon what code is this kernel based? Is this a stock Android 4.3 kernel or does it contain Sony code? Is it based on Sony kernel code? If the Sony kernel is open source, after all...
I ask, because the original Sony kernel has some security features that might get lost when using a stock kernel without Sony extensions.
So, does DoomLoord´s kernel include Sony code or is it a "naked" stock Android kernel?
Thanks for any hint!

1. If you use 136, then use V7 for more features and more stable.
2. It is based on Sony Stock Kernel.
3. Flashing custom kernel need unlocked bootloader, which mean you'll lost your DRM key. This is Sony security which you meant, this is not kernel issue, it's just something you get from what you do (unlock bootloader = lost DRM key)
If I missed to answer your questions, let me know.

I did not find a version v7 for the 136 firmware on his website.... Do you have a link?

Well, on the Sony website I found a paper that says Sony added security enhancements to the Linux kernel, precisely some kind of runtime control mechanism that is not part of the standard Linux kernel. Thus, there is actually some kernel enhancement by Sony to their Linux kernel. This is why I asked, if DoomLoord uses the Sony kernel source these enhancements will be part of his kernel. If DoomLord does not use the Sony kernel source, these enhancements will not be part of his kernel.
Besides, does it require a kernel change to root a device?
Thank you!

Repair with official firmware and check the camera there or flash latest gdx top on nAa kernel
The official firmware it will flash stock Rom and kernel to
Info:
Also if you have plans to relock the bootloader must do it only in stock kernel..NEVER RELOCK BOOTLOADER ON CUSTOM KERNEL

Try to flash with eclair 2.1.1 :good:
Hi, I need to install JB 4.1.2 or something like that, but the original one... or some custom rom with minimal changes. This is because I need to know the built-in options of this version of Android, so yeah, I need the "boring" version.
The thing is, I have a custom kernel [2.6.29.6-nAa-14] on E15i (and thus, baseband), so I don't know if I need to do anything else.
Thanks.

you can't install the official jellybean update in x8 because there's no official jb update in our x8. you can try a custom rom like cm9-11 wich runs a unofficial jb rom. I know they works great because our x8 developpers for custom rom is superb. you can see it in our development board.

I don't know what you mean by Original Version. Our phone only got Officially updated to Android 2.1 by Sony and to 2.3.7(CM7) officially by CyanogenMod. The closest thing you might get to "Original" if you want to get Jelly Bean 4.1.2 would be MiniCM10 or JB Mini Project. You will need to Upgrade you Kernel to 2.6.32.61-nAa-06 for MiniCM10 and to 2.6.32.60-nAa-05 kernel for JB Mini Project.

I dont want to unlock bootloader, so I would like to know if stock kernel is ok for custom ROMs or should I unlock bootloader and flash any custom kernel too?
II use exiastenz with stock kernel. I tried other kernels as well but after all I went back to stock kernel. But. I stay with unlocked bootloader while I can easily bring back my phone to life after messing too much in system when I recieve a bootloop at Sony logo I just flash doomlord kernel with cwm and then I can flash everything else. But with normal use I prefer stock kernel. Don't need to overclock with such hardware. Don't need to emulate cdrom or other stuff. Don't have time for that. Maybe a year ago but now I don't test new features.
As a summary. Is worth to have unlocked bootloader. But for normal using of device use stable stock kernel and .201 software.
You have to know that some of non stock ROMs NEED special kernels. CM 11 for example.

Yes, I know some about stock and non stock ROMS and when non stock kernel is needed. I had Live with Walkman (Xperia 11) and I needed kernel to OC because 1GHz was not enough and there were plenty of various kernels. Yet it was the only my android device so I need to renew my knowledge base.
So you would say, that stock kernel is enough? Or is it that custom kernels for SP does not differ much from stock kernel?
Also, if I want to flash CWM (recovery menu), do I need to unlock bootloader?
Is warranty void with root or it has nothing to do with warranty?

In my opinion Xperia SP has enough hardware to normal use, and also heavy gaming. Stock Kernel have all features which I need. OTG work, I dont overclock my CPU, more... I underclock my CPU frequenzy. I dont want support of NTFS and other things which can you find in custom kernels. So stock Kernel is enough.
Warranty. You Void your warranty when you unlock your bootloader. But you can always relock it, flash stock ROM and you will have your waranty again.
You dont have to unlock your bootloader to flash (install) recovery. You need root only.

I don't think so, it's 4.12. Either you stick with stock based 2.5, or you go to KK.

Hello mate.
1) On the title you are say that you want to install custom roms for unlocked bootloader, so i suppose you are talking about roms like cm11 etc.
In this case you don't have to root your device because unlocking your bootloader and so flashing a new kernel and that kind of roms most of the times are pre-rooted.
2) You can access the recovery mode by using the UP volume key.
Some custom kernels, such as the one from DooMLorD have integrated 3 recoveries, so you can use the Volume UP key, the Volume Down key and the Camera button. Different buttons have access to different kind of recoveries.
3) You have to try and see the rom that suits you more. Some users prefer cm, other stock roms etc. The only solution for you is to try and find the one you like more.
4) Last but not least ----> Don't flash kernels from other devices to your phone. Only if the kernel is developed for the Xperia V you can use it.
Kernels are device and firmware specific.
You can't install a kernel from the Xperia T to the Xperia V and you can' t install a kernel made for JB 4.1.2 to JB 4.3
Hope these tips can give you a hand

Hi,
im new xperia Z1 C6903 user.
I had previously samsung phones
I use archikitchen to make rooted/busyboxed/deodex rom ( using cache.img , boot.img , system.img.ext4 from stock firmware)
I want to make my custom rom for C6903 ( not deodex patch) and i have some question to developer's:
1.How to deodex stock firmawre (*.ftf) ?
2.Why xperia custom rom's don't flash kernel in installer script ? ( only to make choose for users with L/U bootloader? )
3.And what i need to know to make fully working custom rom for xperia z1 device ( generally what are the differences in creating rom compared to for example S4 phones)
thank's for your all support :good:

1. If you can hack FTF with still using Sony signature, you are genius
For this, you cannot deodex stock firmware in FTF
2. Because Xperia implement Locked bootloader, not like Samsung
Of course, this is for security reason
And I dunno, even with stock kernel I'm still using flash kernel via flashtool, I never try to using .zip for flashing kernel even I'm want to flash stock kernel
3. You must know what device you're using, and many part of system also kernel
If you can understand them all, you can make a rom like what you want
In general, custom rom for Xperia and Samsung almost same, but different signature and configuration make them different
And from your question, you still learning how to use Xperia, so take the long trip slowly
=)
And for deodexed, you must still using deodex patch, it's same with what you doing with your Samsung phone, but only using another way
=)
