Noob Question: Why crack the bootloader? - XPERIA X8 Q&A, Help & Troubleshooting

Hey guys I've searched around the net and couldn't find an answer to my question, I'm a noob to android so don't eat me. Anyways I've read that the Bootloader makes that we boot to the signed kernel so that we can't use custom roms. But the X8 has a locked bootloader don't it? But we're using custom roms like FroyoBread, Floyo, MiniCM, KuyaDroid and GingerDX. What more can be achieve with cracked bootloaders? Well I mean since everything on FroyoBread works.
Thanks in Advanced,
Anzzle.

you can boot custom kernels and if you want to know more -> search this forum -> type bootloader and read all you want to know

I have searched :/ It said it "allows the use of Custom ROMs" But aren't we already using custom ROMs like FroyoBread without cracking the bootloader? What are custom kernels that you speak of?
Thanks.

Benefits of unlocked bootloader: no modules no more... we'll have all those things in kernel itself.
More stabillty and performance..
Native overclock, undervolt, overvolt when needed...
A lot of other tweaks like incrasing in-call volume etc...

and then there is another one on development section
http://forum.xda-developers.com/showthread.php?t=921652
cheers ,
1. Root your phone.
2. Install xrecovery.
3. Install a custom rom, (Froyobread recommended)
4. Install overclock modules.
You'll find tutorial for each step around the xda forums.
thanks guys also i wanted to know,, how much overclocking is safe and how much isnt???
hey
can you tell me where i can find the a detailed forum on how to root your phone??

okay man im using foryobread now!! looks awesome soo far!! thanks ,,
Usually higher "v" means more features (and maybe more performance), but maybe lower stability.
FroyoBread, in my opinion, is stable at v023b
now that i have rotted , installed xrecovery,, using froyobread,, where can i get a overclock module??
Look in my signature dude.....
I have used Froyobread since v12 and i loved it, until GingerDX arrived. I would give it a try if i was you as its from Doixanh who created Froyobread and its so fast and smooth, also check this out http://forum.xda-developers.com/showthread.php?t=1151293
its multiboot and its good, also attached in the post is dualrecovery.zip which will give you both xrecovery and CWM. Have some fun and remember that the bootloader is locked so go mod your phone in the safe knowledge that pc companion will fix any problem i have come across.

[Q] Questions?

what is swap?
what is ICS?
what is MIUI?
what are modules?
how can i install kernel(and what are benefits of that)?
can i install it without unlocking bootloader?
my phone:xperia x8
custom ROM:gingerDX.v022
pls help and sorry if copying some thread.
H'm... there you go.....
Ics - Ice cream Sandwich android 4.0
No you cannot get custom kernel without unlocked bootloader
Modules I don't know the exact term. just Wikipedia it.
it basically add some features that you get on custom kernel while you use stock kernel

Most of your questions is solved by Google, anyway, here we go:
1- ICS = Ice Cream Sandwich - Android 4.0
2- Miui = ROM/firmware based in Android, but with a nice interface (more info http://en.wikipedia.org/wiki/MIUI)
3- Modules are tiny scripts that you have to load in stock kernel to get dual touch, over clock, etc.
4- Download FlashTool (Google it) to install kernels. Custom kernel have modules already buit in, support for swap, and a better performance overall.
5- You have to unlock your bootloader.
if i try to unlock i can trow my phone into garbage! (11W44)
if you cant unlock bootloader, you can use your stock kernel with modules. such as multitouch, overclock, undervolt, etc.
- download it from threads,
- copy to ur /system/lib/modules/,
- then edit your hw_config.sh,
- add this script "insmod /system/lib/modules/<module>.ko"

i already changed my CPU frequency from 600mhz to 729.6 mhz
what else can i do with modules??
suggestions pls!
you can get dual touch I.e pinch to zoom will work..
fake dual pincth zoom already have!
other things?
Ok, since there are no really helpful replies ... though most of the question can be answered by doing some research in the forums (I know: *effort* *reading*)
mario1024 said:

Click to expand...
Click to collapse
swap is virtual memory on either a separate partition or in a file to where the kernel can swap out currently unused memory pages to free up real RAM.
This is NOT "magically upgrading RAM", this may just help to get RAM-hungry apps (i.e. Games that behave like a resource hog) running.
Note that using swap may degrade the lifetime of your mSD card considerably when there's a lot of swapping going on!

Click to collapse
ICS is short for Ice Cream Sandwich which is otherwise also known as Android 4.0.x
Donut - Android 1.6
Eclair - Android 2.0 / 2.1 (yes, Google failed to come up with a new name for 2.1)
Froyo - Android 2.2
Gingerbread - Android 2.3
Honeycomb - Android 3.0 (was only meant for Tablets)
Ice Cream Sandwich - Android 4.0
Jelly Bean - Android 5.0 (not out yet)

what is MIUI?
Click to expand...
Click to collapse
A custom ROM that was originally built for ARMv7 devices (i.e. Xperia X10). Now that the MIUI team open sourced the ROM it can be ported to the ARMv6 architecture of the X8/X10mini as well.
mario1024 said:

Click to collapse
It generally refers to modules for the (Linux) Kernel (yes, Android runs a Linux Kernel) which extend functionality - like providing support for other filesystems (ext3, ext4), CPU governors (frequency scaling), Dual Touch, Undervolt, Overclock, etc etc

No, you can't install a custom Kernel on your phone due to the date code being too new. So we leave this part out.

No. To install a custom kernel you need to unlock the bootloader. There's no way to boot a custom kernel WITHOUT unlocking the boot loader.
thanks B.Jay
is it possible to make a way to install kernel without unlocking bootloader(in future,I mean are people trying to do that)

No. Impossible. A kernel requiring no boot loader unlock? Thats crazy talk.
No, people are not trying to do that. It is impossible. Easy peasy
The reason that a kernel requires your bootloader to be unlocked is because.....
The kernel is the software layer between the ROM and the hardware. Changing the kernel could possibly lead to either you,or the dev changing the hardware.
Changing the hardware and CPU Requires more than just root access. Sorry if you cant understand this. Im not at my computer. I will edit this tomorrow so it makes more sense.
Anyway hope it helped

For poor people who have lock bootloader

For those who are unfortunate about not unlocking their x8 with 11w30 and above/.... i have a question for u
im on stock kernel and rom and lock bootloader
sorry for asking but i cant seem to find answer if i can change my stock kernel to one of the stock kernel offering of other dev and change my rom to custom rom ??
if yes can u suggest a good rom with good battery life ans stable for everyday use i prefer GB THANKS
Well, stock kernel is stock because you cannot use the cutom ones offered by other devs. This, however, does not prohibit you the use of cutom roms, you only have to use the ones that support the stock kernel option.
As for the roms, well, check out the sticky in general section for a comprehensive list of various ROMs and their supported kernels (look for stock kernel in the kernels list).
<shameless_plug>I, personally, use GingerDX, a fast, smooth and really nice in overall rom</shameless_plug>

Hi funny name guy.
1) recovery is on mmcblk0p4. You can easily install custom recovery once your rooted. It's in a sticky in one of these threads.
2) If you wan't custom use Huexxs Diana kernel.
3) backlight buttons are from kernel and needs to be integrated. The V30 repack has the functionality built in to modify the timeouts but I don't know of anything that can turn them off.
If your new here go read NOOBY's how to's they have pretty much every thing you need.

Why does it seem outdated? Because of some missing ROMs? Basics remain the same...

[q] how to flash stock kernel

I WAS WONDERING HOW I CAN FLASH THE SONY'S STOCK KERNEL ON A CUSTOM ROM LIKE CYANOGENMOD AND AOKP
BECAUSE ALL THE OHER KERNELS HAVE REALLY BAD BATTERY LIFE
IS THERE A WAY TO RUN CYANOGENMOD ROM ON SONYS STOCK KERNEL ???
I LUV THE SONY STOCK ROM BECAUSE OF ITS BATTERY,BUT I ALSO LUV CYANOGENMOD BECAUSE OF ITS CUSTOMIZATION AND LOOKS
PLEASE LET ME KNOW, IM STUCK GOING BACK AND FORTH BETWEEN SONY'S FIRMWARE AND CYANOGE
First, here are steps in turning off caps lock:
http://www.wikihow.com/Turn-Off-Caps-Lock
Secondly, please search before you post.
Thirdly, if somehow you just can't find what you're looking for:
No, you can't use Sony's kernel on CM11 based ROMs.
You can flash Doom's advanced stock kernel which is just Sony's stock kernel with added recovery via recovery if you want to switch back to stock-based ROMs. It is found in Doomkernel thread, please search for it.
Even we would really like to see AOSP/CM/MIUI on stock kernel, there's no luck...
But...
There are some projects trying to build MIUI on stick kernel so join them and try to help...
..hehe.. Here are steps for turning off caps lock...haha....good one...

CM,PAC other custom roms need custom kernel only..
there are no chances they work on stock kernel....
stock based roms only work on stock kernel
so in conclusion
is there any custom rom out there for xperia z1 that has a really good battery life ?
