[Q] Unlocking bootloader and custom kernels - XPERIA X8 Q&A, Help & Troubleshooting

If I unlock bootloader, and then flash some custom kernel, will i lose all data I have, so it would be like I've done factory reset? Or everything will be the same (just different kernel) ?
Thnak you.

Kernels are building to rom.You can make backup with titanium backup

hi..if you flash with some kernel you dont lose data in SD CARD..you keep wallpapers,ringtones,music etc..all you put in sd stays..even if you make a wipe/factory reset in recovery ,data still remain..just different kernel and new rom.
,

you lose nothing

You won't loose Your data, but there is a chance, that Your phone won't boot up and it will stuck at bootanimation. Remember, that stock ROM works only on stock kernel (if I'm wrong - correct me). Other ROMs may work on several types of kernels, but remeber to check it first

I think you didn't understand me, or I wasn't so specific... I will give you an example...
Now i have ginger dx v022, some modules and tweaks installed on it, and I changed few things to fix notification bar and wifi (eduroam)... and if I flash alfs kernel, for ginger dx, can i just restore system backup with xrecovery or cwm, or will i have to 'install' ginger dx v 022, but everything (apps, modules, tweaks etc.) will disapear?

Nothing will be changed just the kernel. And for gdx flash Alfs kernel.
Edit: you don't need full wipe when you flash a kernel.

Thanks a lot, I will do that for a couple of weeks when i got bored with stock kernel. But with stock kernel I also have great results and speed...

You decide mate. But I recommend custom kernel cuz it has the latest and built-in recovery, better gaming performance and makes your device faster. +now the best roms (except gdx) are working only on custom kernels.

Hi, the overclocking in general reduces life span of the cpu.
http://www.pcguide.com/opt/oc/risksRisksCPU-c.html
from my personal experience on this phone its quite safe to o.c to 1.4Ghz.
just mind the temperatures.
i installed swiftkernel .. it can be overclocked to 1.2 ghz .. will this be safe and can you kindly suggest me with the best rom and kernel .... may be the one that you are using .. once again thank you very much for replying to my query!!!!
Personally I love cyanogen mod, I'm using nightly build 200 and its awesome. Naturally you should get the newest one.
Vorkkernal is best for cyanogen and miui roms.
You will not break your phone overclocking. on very very hot days maybe go 1ghz to be safe.

Hi again
i would suggest stock version v20L de-odexed by Paul ,
http://forum.xda-developers.com/showthread.php?t=1328656
the reason for de-odexed system is simply because it lets you use the kitchen for further customizations, also the version by paul is pre-rooted. which will make you're life easy.
the reason is simple. everything works fine atm in the stock rom (yeh people always complain..... so dont flame me for sticking to the stock, but for me it works excellent)
cyno is great as well, also topo and the rest , the ppl here are doing a magnificent work but you need to remember that all of this is work in progress; therefore i suggest you will use the stock rom for the start.
i.e. 1 week or so
and see if it fits well with you're requirements. if you don't have any issues than that's ure solution if u got issues with stock drop a msg here with the problem description and we can see what can we do.
hope i helped.
is it the same way as we flash other rom???? i would suggest stock version v20L de-odexed by Paul ,

the procedure is simple.
download the file to the SD
boot to CWM, wipe data / cache and dalvik cache , and then apply the zip.
the package is ext3 i assume you come from stock therefor there should be no issue.

Yes i did it !!

I find gdx v20 best for day 2 day use
Sent from my MOLEY_X8 using xda premium
for me..
and hightly recomment is GingerDX v20
and when you know after reading thread by thread you can match with kernel
linuxDX, or Alfs kernel, or nAa kernel...
it can simply make your device faster and smootherst
but beware if you new on kernel
(make sure your know what are U doing when playing with kernel and unlock bootloader)
because it can brick you phone!
and then I sure after this you will screaming here and asking how to save your bricked phone!!
here the answer use SEUS
gingerdxv20 for sure

U have to follow installation properly
make sure install GDX with CWM instead Xrecovery
and fullwipe..
or maybe your device 'special' same like my friend phone
(when I flashing GDX 20 and GDX v19 on his phone)
I found this problem = sdcard no show
but when in recovery = all files and folder prety there
and I have no idea why....

when u reboot..
press volume down key or/and tap screen (when u see SE white logo)
u'll see CWM recovery and install GDX by this way
or if u can get into CWM th8 mean U don't have CWM
so install dual recovery.zip first (u can use search button)
or install other rom which one have dual recovery pre install
sorry long explaination
and hit thanks button twice!
thanks! (thanked already )
so in summary ...
open xrecovery and find CWM
if CWM is missing then go donwload it...
is cwm same with xrecovery?or is it and extension?
then use cwm and install the mod instead of xrecovery (do i need to system wipe?)
reboot phone then done?
hmmm just wondering will my link2sd apps will stay?
does it have anything to do with busybox? according to dotsen i must not update busybox

[Q] Fastest rom (+battery saving)?

What is the fastest rom for X8 with stock kernel? Should also be battery saving and not ram consuming, but most important: FAST
I dont need a very good looking rom with fancy widgets and lots of functions or setting, just fast and battery saving

PrimeHD for Stock Kernel is ur answer!

Sent from my Nexus S using xda premium
Thanks, i'll flash primehd tomorrow as you wrote: "there is going to be v5.4 for all kernels, I will finish up my last checkings and upload the files tomorrow."
So i dont have to flash 5.3 today and 5.4 tomorrow
Just to be sure....i just have to boot into cwm, do a full wipe and install primehds53 (or tomorrow primehds54) and then reboot and let it boot into primehd?
I'm asking this because there is a hotfix file too and somewhere i read that i have to install google apps and i dont know if the hotfix file is ment or not?!
thanks in advance........i'm really looking forward to using primehd

[Q] Can bootloader be unlocked with GDX v025?

I read this:
http://forum.xda-developers.com/showthread.php?t=1436957
but i don't have the stock ROM, and was wondering if i can unlock the bootloader on GDX v025. I have a W8 with 11W20 and i plan on installing MiniCM9. Also, i read this:
http://forum.xda-developers.com/showthread.php?p=24304432
What does he mean about flashing it to Gingerbread ROMs? I'd appreciate the help.
And is getting the stock ROM as simple as downloading it and then flashing it with CWM? and will i need to update it to the latest basebands or is there one already updates that's available?
Thanks

It's is highly advisable to be on stock ROM. Just flash it via PCC/SEUS. Why this is required , I don't know. But always people recommend unlocking on stock ROM. I too would therefore recommend the same. Get back to stock ROM
Don't risk it by unlocking on GDx v025
What he means that the kernel is meant for ICS ROMS only and is NOT meant for GB or stock ROMS
Another thing
So...
1) Flash Stock Rom using SEUS (will this be the one with the latest baseband and will my phone still be rooted?)
2) Unlock Bootloader while on Stock Rom (as stated here: http://forum.xda-developers.com/showthread.php?t=1436957)
3) Flash ICS kernel while on Stock Rom (as stated here: http://forum.xda-developers.com/showthread.php?p=24304432)
4) Flash MiniCM9 (as stated here: http://forum.xda-developers.com/showthread.php?t=1575094)
Am i right?
Also, is it necessary to install all to Google Apps which nAa has provided a link to?
And where does the currently rooted state of my phone lie in all of this?
Thanks

Not sure about SEUS , but if you use PCC , your phone gets unrooted.
I guess both ways, you have to root again. But that's not a cumbersome task. Just use superoneclick and then place xrecovery files in /system/bin
Just make sure that after flashing the kernel , you flash the ROM directly after it. If you reboot your phone after flashing the kernel , you will encounter a soft brick.
It is not necessary , but recommended. I would suggest that you flash Gapps (Google Apps) , and then manually remove the applications you do not want by using apps like "Root Uninstaller" from the Play Store.
I did not understand your last question.
I am 99.999% sure of what all I told you is correct. However , since I have a locked bootloader , I might have missed somewhere (I'm sure I have not though)
I unlocked my 11w18 with GDX , no problems

How to start from "zero"?

Hello, I'm kinda newbie at this...
I have an Xperia X8 e15a with manufacturing date 11W11 @ stock kernel, running with GDX v026.
but lately I've noticed that my phone is too slow... even when I get incoming calls, its hard to slide the bar and answer them, so I want to know how can I speed up my phone. I'm thinking of changing the ROM to PrimeHD or other ROM that is faster.
I also think of the possibility of changing to a custom kernel but I'm afraid of bricking it because I remember this phone was from X company and I entered a code on internet and now it works for Y company, so I don't know if thats a real SIM unlock (bootloader unlocking says the phone must be sim unlocked). Oh... and I wonder if I could make a swap partition... I don't really know how to do it, I've just made them on my PC so I'm not sure if I can do it on my phone.
I feel like my phone is messy... I've seen 2 kinds of recovery tools and I just wanna have one (CWM and xRecovery). Does full wipe delete them? I would like to go back to the very begginig (without unrooting lol) and then change everything from the start :S.
Thanks.
PD: long story short:
What ROM is fast?
how can I make a swap partition?
can I unlock the bootloader to have a custom kernel? (having in mind that I introduced a code online to "unlock" my SIM)

1st check with s1too is you have sim lock certificate(if yes, you can unlock your bl)
2 you can try yourself there is no perfect rom for everbody
You need a partition on your sd for use swap

I just unlocked my phone...
Well I know there's no perfect ROM for everybody, but I'm just asking for some recomendations on fast ROMs... :B
is PrimeHD fast? is any other ROM faster than GDX?
And about the swap partition... is there any requirements? I remember I wanted to do it back then but I don't remember why I didn't xD
thanks
If you've already unlocked bl, switch kernels. That would help a lot.

Still if you want to, use it with a class 6 or 10 sdcard

Maybe you should give GDX another try, now that you have unlocked your bootloader. I used to use GDX with stock kernel, but like 14days ago I unlocked my bootloader and flashed ALFS kernel for GDX and now the ROM is like it never was before, super smooth and fast.
