Noob Question: Why crack the bootloader?

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...

[Q] Some Question From Noob

First, I want to say Hi..! to all of you, because i'am new here.
i have some question
1. is there a "recovery partition" on OB, because some phone doesnt have it, for example SE Xperia X8, which recovery is located on /system partition.
2. Any recomendation for Stock-custom kernel for Stock GB 2.3.4, that have many feature(OC, UV, GPU OC etc etc)
3. Is there any app that can turn off 4 button backlight???

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Why does it seem outdated?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...

rom with orginal sony's apps ??

first i have a w8 with 12w02 and i see a lot of roms with stock kernel but all of them (as i know) based on CM, so i really miss sony's apps like alarm, clock...
guys pls tell me a rom is a ported from xmini, lww... so we both have ginger bread and sony's apps
tks

But they are good roms, just try. As i know its not possible to port from 2011 devices. Cause they are armv7, x8 is armv6

Try the old (but good ) GingerCruzt rom. This have SE look, and use some original SE app. Up to 8.4 it works on stock kernel (the latest 8.5 require custom kernel). And some xgin roms use some SE apps (widgets, contacts app, etc) around version 5.6-6.0. These roms is abandoned, and hard to find working download link. Unfortunatelly only these old hybrid solutions exist (cm7 + some SE apps) for stock kernel. If you lucky, maybe in the android development section you can find newer stock based roms what contains original SE apps (I not follow every rom threads), but do not want too much, these roms usually contains only SE launcher, timescape, some original widgets, dialer/contacts, xperia themed message app, 50-90% xperia look, and some apps what have modified UI to look similar to the SE apps.

Try semc Debrand by achotjan little buggy but stable and workable, does require custom kernel tho

unfortunately, the op's date is 12wXX. so unlocking his bootloader is a huge risk.
@op: i understand your preference for sony's stock apps. but there are a lot of nice alternatives for them. if you don't want that, stock rom is pretty good (considering the situation).

i tried to unlock boot loader but when clicked msm7227_whatever.bat it's failed lol
and now i think unlock bl for what, it's still arm v6 and it's still slow, i just need a viber and walkman device so better to stay away from risk )
tks you guys all, i'll try these roms.

i tried to ub my phone few days ago and got a hard brick
but luckily it's under warranty, so now i've got 11w21 hurayyyyyyyy

I guess u got lucky Now i guess u can unlock your phone's bootloader. For custom rom with sony look and feel i would recommend Gingercruzt 8.1/8.5 for stock kernel and 8.5 for custom kernel

Gogeta not 12w02.He have bricked the device and give it to warranty.Now he have 11w21,so i think it's safe to unlock the bootloader.

I don't know...About the risk i think that it would be better if you won't unlock your bootloader,because you don't know what date of manufacturing you have, and it's not with old kernel.This is the date of manufacturing the motherboard.
@voncount from who you know that you have 11w21 ?

I think GingerCruzt or XGin..

[Q] request regarding android 2.3 rom for xperia x8

guys, my phone has basically 2.1 which works well in multitasking. i have tried few roms available in the internet, but none are working properly. for example if im browsing and i get a call, after the call is ended, by browser gets closed automatically or it restarts and i loose all by tabs. same is with other apps, when i use one others are not kept open in the background.

Better increase ram by using swap & flashing a custom kernel (if you càn)

The rom for you is GingerDX , also if you want more multitasking performance unlock bootloader and use alfs v09c kernel
Sent from my Nexus 7 using xda premium

Use latest GingerDX v30 (CUSTOM ROM) with Jimdem Tweaks if you in Stock Kernel craving for more
performance. (need Root and install recovery)
if need more performance and cool features and great responsive
you should flash custom Kernel like Alfs and nAa(Need unlocked bootloader) Warning may Brick your device!
i recommend you to use GDX V30 + Jimdem Tweaks.in stock kernel
that will ends your craving for a great ROM!
okay here the thread i founded.

Thanks guys.found a solution. I have used task manager and identified the useless apps coming in background and frozen them with link2sd and im now using opera mini for regular mail checks and boat browser only when needed. Now it seems good enough.

i don't know if it work with other Kernel because my X8 is only Stock(LOCKED)
remember to wipe data before Flash (not compulsory but Recommended!)
here is the Thread link i founded learn there about the Tweaks features and cool benefits its specially designed for GDX Rom's

nobody mentioned it so i would like to point it out here... it may be because background data might be off?
and if you get a phone call then your net gets disconnected. that might be causing it.

And why don't you use 2.1?:silly:

C6903 - CyanogenMod 11 for Locked Bootloaders - Help needed!

Hello guys, I'm acquiring some info about how to build the CM11 to Honami with locked bootloader.
 @Olivier already did it to Xperia S and @letama said to me that MAYBE we can do the same to Z1.
I'm not a dev at all, but for sure I have some skill (I hope!).
So, I have to ask first, did anyone already tried it? Worked? Didn't work?
If anyone is willing to help, please, let me know.

Impossible workout kexec, and that does not look promising. Is in the original development section.

Well, this solution doesn't use kexec. It basically hijack stock firmware android boot to boot the alternate firmware but it's using stock kernel, that's why it can work with locked bootloaders. The only requirement is that cm or aosp should run on stock kernel and doesn't require a modified kernel. As you have kitkat on your device, there is a good chance that it does.

But it doesn't, that's why it does not work and a modified ramdisk (Hence modified kernel, hence unlocked bootloader) is needed
Hence kexec is needed, but that seems like a lost hope on Xperia Z devices

Nothink is imposible i hope

No, nothing is impossible, but there has to be enough effort spent on it.
Personally I don't think there will be as most devs got bootloaders which can be unlocked...hence they do not need kexec
In future its always preferable to check this before purchase

mabe don't need to unlock bootloader but workaround this - mabe multiboot or kexec will be more developed because more phone will released with LB and this is their new policy :/

Ramdisk is not a problem... When I say kernel, I mean zImage, not zImage+ramdisk: we extract cyanogen ramdisk in the boot hijack.
Kernel drivers combined to Android hal is what I meant and could cause problem depending on how Cyanogen was developed and how Cyanogen kernel source code is far from stock one. That's why we're usually stuck on Cyanogen with the same Android version.
Another solution is to hack Cyanogen code to support stock zImage. It's not for the faint of the heart, but it could be the only solution.

Greg's absolutely right, if your bootloader unlock allowed status is no or you're unwilling to unlock it then i'm afraid you're out of luck, i'm not saying it's impossible that just isn't true, but again as Greg's said this more than likely isn't going to happen as it would take some talented folk a lot of time to accomplish it, with the Z2 having been released and the vast majority of people able to unlock their bootloaders there is little call for someone to have a crack at it.
in all fairness though, the rom's that are available for locked bootloaders are pretty damn good and the launchers that you can install these days gives a near perfect android experience, you'll only be missing things like Halo and custom kernels along with a few mods and such that only appear to be available for cm based roms and the like.
