So a thought that has occurred to me since I got this phone is one of haret.exe on winmo phones. basically boot up past the bootloader and kernel(that are locked) then using either 2ndboot or kexec dump out of that kernel and launch out own kernel/filesystem
Sadly in looking around 2ndboot seems to require the phones kernel source(which we don't have, unless i'm totally wrong)
kexec on the other hand seems to be a much better way to accomplish it. Again this is mostly useless without a kernel BUT we could take our current kernel to use as a test bed for if (as is required) the release the kernel source.
Thoughts? anyone wanna join with me on trying to get this running and tested?

I believe this was discussed already in the thread about cracking the bootloader, however, if you do manage to get this running I will gladly beta a new kernel as long as there is an SBF file available at the time to allow flashing back to stock.
Cheers
Ill gladly beta as well. So long as we have a method for recovery.

look im a n00b(still learning android stuff),
so this question is just out of curosity
why cant we have kernel 2.6.32 ??
well google said froyo needs atleast 2.6.32 to run
but we here are running gingerbread smoothly on 2.6.29(thnaks to all the awsoms devs )
can someone knowledgble reply
thank you ;p
Simply because the kernel drivers needed for the X8 only exist in Linux 2.6.29 as published by Sony Ericsson.
If you would want to use a newer Kernel release (i.e. the ones Google is using for their Android builds) you need to port the drivers to that kernel version - read: make them fit the kernel.
That's a very tedious process, so it's easier for the ROM and Kernel developers to base their work upon the original SEMC Linux 2.6.29 sources.
on short: its easier to port drivers from 2.6.32 or 35 or 38 than make the base 2.6.32.... working on our phone
as b.jay said, porting kernels takes a long time, and if you recive only a couple of errors in the middle of it, BOOM, you gotta go back to the sart and track what wrong command you typed or what code is wrong etc. thats why no one has ported 2.6.32 kernel.
to many drivers to cope with, to much errors that you will recive. porting roms is easyer
thanks guyz for the answers....in short it is possible to have kernel 2.6.32....maybe nAa can port it....he has already backported some stuff.
It is possibe given someone wants to spend an insane amount of time (edit: we're talking several weeks to several months here) in forward-porting the Shakira specific drivers and additions to the ARM Linux code base.
I don't see it happen as it's a enormous undertaking for a single developer to port the whole stuff - that would require a medium-sized team of coders a) knowing what to port / b) well versed in Linux Kernel hacking / c) knowing how to code for ARM (edit: as the existing sources most likely need to be adapted to the Kernel ABI (in this case 2.6.3.x), which is not exactly stable in Linux and changes erratically as Linus' maintainers see fit. Also, don't forget that the changes need to be tested to see if the kernel boots and works flawlessly).
Don't hang your hopes too high.
need to much time to update linux version of kernel
But for instance lg optimus p350 has almost same specs but runs .32 kernel.it has same qualcomm 600 mhz cpu,ardeno 200,and 140 mb ram.so x8 has even better specs.so i dont se why this wouldnt be possible.

Im left with the kernel source for my device and the dev told me its good to update msm_fb and other stuff to make it more usable...
anyone can help me with that!!im looking and taking some commits from various gits but im stuck to this cause i can't find the same diffs for my device...if anyone have msm_7x30 device and willing to give me some hints...i need to make the device more snapier on 4.2.2 cm and a bit faster as it can be cause its single core...but even on 1400mhz its still laggy!!!
Any help i will be greatful! thanks!!
i think you have to study commits in github done on similar kernel for device.msm_7x30.
Welcome to the first custom kernel for the KitKat Shield.
This thread is for the development and building of the Shield Portable kernel.
This is not intended to download a build, post issues, and return when fixed.
Kernel Source:
https://github.com/StarKissed/starkissed-kernel-roth
Kernel Downloads:
https://goo.im/devs/playground/shieldroth
The kernel can be built using the commands below or the included script.
Code:
make tegra11_android_defconfig -j$CPU_JOB_NUM ARCH=arm CROSS_COMPILE=$TOOLCHAIN_PREFIX
make tegra114-roth.dtb -j$CPU_JOB_NUM ARCH=arm CROSS_COMPILE=$TOOLCHAIN_PREFIX
make -j$CPU_JOB_NUM ARCH=arm CROSS_COMPILE=$TOOLCHAIN_PREFIX
App & Donations:
StarKissed [SKU] on Google Play allows you to configure many of the options provided by this kernel. Issues or comments about the app can be posted at the XDA StarKissed app thread
Donations are not being collected through the forum. If you would like to donate, you may do so through StarKissed [SKU] on Google Play by using the donate options located in the top right (the green dollar bill guy).
[Kernel] Shield Kernel Development
The included ramdisk is for update 98. If you are on 72, this will most likely result in a bootloop. Using the 72 ramdisk will not work with this kernel, as the source is specific to "OTA 5" according to the Nvidia gitweb.
I recently updated the source and changed a few commands that may explain why current source resulted in non-working builds. I will be testing builds soon and then begin modifying the kernel once the core build is verified working.
Nice, I hope there will also be an overclocked kernel for 4.4. I know it's silly but I miss the 4.3 overclocked kernel.

All the code is there, it just loops. I'm not sure what's going on with it. The shield tablet version works.
Quick question. Any chance you could update the usb ethernet drivers in this? Specifically, I'm suffering from this bug on an ASIX 88772 on the official kernel, and it seems their driver is rather out of date. Thanks, and keep up the good work!

Won't do much good until it boots
True enough, just thought I'd bring it up since it's a fairly easy fix. In the meantime, I threw together a stock kernel with an updated driver to get by. I had one problem after another with the latest official driver, but the good folks at LKML had already put some work in on v4.1.0 several years ago. Using drivers/net/usb/asix.c and usbnet.c from the 3.4.106 source built without problems.
Beginning to think I may have to settle for building against the full source on this one. It boots fine when doing that, but not built alone. The shield tablet builds fine alone, so there's no explanation for it.
you are going to make a new build of your kernel? if you need help with the tests i can help.

Things are a bit crazy, but once I can get all of the changes fixed up and it'll build clean, I'm going to try to run it over night.
Slightly off-topic, but I'll ask you since you're the only other person I know building a shield kernel. I built nvidia's kernel, changing only the two drivers associated with my ethernet, but for some reason console mode has stopped working now. Have you ran into a similar problem? Plugging HDMI in pops up the selector, but clicking on console mode doesn't do anything - it just stays on the selector screen.

It shouldn't be related. You may need to check the proprietary drivers. I believe HDMI is one.
Didn't bother to find out what the problem was, it just stuck around because I was doing dirty builds as I tested. Once I got a few other tweaks and had some time, I did a clean build and it resolved itself. Did you manage to get your kernel booting when building it by itself? I'm sure I'm doing something wrong there too, but I've been grudgingly building the entire device, since that at least works reliably.
What is so special about this kernel compared to stock ? goodjob already btw, you're one of the few who actually have a kernel
It's really sad how not much development is going on, it's such a good device there is only like 1 release at the original section :/
Hi all,
I have a rooted sm-t810 running stock marshmallow kernel 3.10.9.8374498 and I have been trying for a long time to add support for my xbox 360 wireless dongle and controllers.
I read a lot online about it and it seems that I need to load a specific module (xpad.ko) that is not available by default in my kernel.
However I have no idea where to find one that is compiled and compatible with my kernel and I have absolutely zero experience with compiling the kernel and/or the module from source, I wouldn't know where to begin or what to do about it.
From what I understand I should download the source of my kernel in a linux desktop, compile the module in it, copy the compiled module to my decide and run insmod it, but again, I have zero experience in all this.
Could somebody help me by giving me the compiled xpad.ko for my kernel?
If not, could you tell me step by step what should I do it to do it myself assuming im a total ignorant in kernels,modules, their compilation, the specifics about android, and everything around it ?(before yesterday I didn'teven ever rooted my tablet )
Thank you in advance if anybody is willing to help!
Cheers,
Mastro
