Boot loader - XPERIA X8 Q&A, Help & Troubleshooting

Hi guys. I'm new to xperia x8. And I read some of the ROM's thread, and the dev says the bootloader have to be unlocked to flash the ROM. Is this true ? So my question is do I have to unlock my bootloader ? How do I know whether my phone is sim lock or not ? My device is Xperia X8 E15i.
And here's my device.

The reason to Unlock the Bootloader is that you are able to Flash a Costume Kernel. There are ROMs for Costume Kernel as well as for Stock Kernel(The Kernel your phone already has). The only problem is that if you are on Stock Kernel (Locked Bootloader) you are only able to upgrade to Android 2.3.7 Gingerbread. If you want to upgrade to Android 4.0.1 ICS or higher you will need a Costume kernel and there for have to Unlock your Bootloader. I don't recommend for you to try to Unlock your Bootloader since you phone's manufacture date is over 11W29. IDK what SIM-Locked has to do with any thing but if you want to check try inserting a SIM-Card from another Carrier to see if it works.
BTW click HERE for a list of Costume ROMs for both Costume Kernel and Stock Kernel.

Alright. Thank you for your explanation. You cleared all my doubts now.
And I have one last question, so let's say I want to flash this ROM ( GINGER ELITE ), it's a GB version. And that means I don't need to unlock my bootloader to flash that ROM. Whereas if I want to flash the XPERIENCE ROM ( which is based on JB ),I MUST unlock my bootloader. Am I right ?
Ps: your thread is looking good. I can consider it as an index of X8's ROMS. Great work, keep it up. :good:

okay 12w05 there is a paid way to unlock bootloader req in forum.... and when you are looking for a custom ROM please read the installation instructions and descriptions before installing, every deV mentions his method of installing and requirements so for your GINGER ELITE read the full thread properly it will b mention there whether it is for stock or custom kernel... diff b/w stock n custom kernels is STOCK= can flash the custom rom without unlocking boot loader. Custom kernel=required unlocked boot loader

I also want to add that if a ROM is Gingerbread it does not mean that it is for Stock Kernel. In my List, the Kernel that the ROM supports is in parenthesis. As you can see there are some Gingerbread ROMs that are only for Costume Kernel.

I am newer too. I also want to know more about it, sorry for my poor english.

[Q] If i want to use stock kernel rom do i have to unlock bootloader?

Hello guys.
My question is do i have to unlock the bootloader for flashing a stock kernel rom like Sony Ericsson 2.1.1.C.0.0? I'm not sure when the phone is manufactured, cause i sent him to repair shop, not because of hard brick it was something else and the sticker is crossed over with pen.
I think the answer is YES, you will need to unlock the bootloader to install any kernel by using FlashTool. Or else you will need SEUS or PC Companion without unlocking. Hope this helps.
Please also see this post for the instrcution on unlocking bootloader.

Why do you need to flash stock kernel? If you have not unlocked your bootloader you are already on stock kernel..
And to flash any ROM you do not need to unlock bootloader..

No, you don't have to unlock your bootloader to flash a Rom which require stock kernel...

of course you dont have to unlock bootloader in order to flash a rom which require stock kernel, you unlock bootloader in order to flash custom kernel!!!!
Thank you guys for quick response.
Cheers!!!
I Don't think u have to unlock the bootloader it's not required for a Stock kernel .. or either a Stock ROM.. Cause the reason u unlock the bootloader is to be able to install Custom kernels .. Like Alfs... nAa ..
So it's as simple as NO.. u don't have to unlock it .. Just install The Original ROM mate ^^ ..

My apologies. My GNote(international version) is on official Samsung ICS & I just want to root it for the time being till a solid custom ICS based ROM is developed. To clarify I'd like to know which of the stock ICS ROMs in the list(in the thread mentioned in my first post) should I use to flash my Note with. I'm not a dev so if there's a risk in rooting the official Samsung ICS ROM then I'll wait till it's safer. What would you suggest sir?
I got my note yesterday and was overwhelmed with all the threads I ended up flashing ics in Odin and used speedmod kernel. Now all is good and using cleanote ROM.

I'd go back to Gingerbread to root it. Then, I'd flash a GOOD ICS rom (something CM9 based). But that is my opinion, I just don't like stock TouchWiz.
You can Odin one of those stock Gingerbread ROMs from DrKetan's thread in Android Development. I live in the U.S. so naturally I didn't have a country rom so I just used Open Germany. It doesn't really matter.
To root it use this. http://forum.xda-developers.com/showthread.php?t=1647148. I already tried in lq2.

Righto. Just a few questions... I went through the entire thread and found folks were having some issues. So:
1. Are you getting permanent full root via this method & SuperSU? Or is it temporary?
2. Any Wi-Fi/ overheating/ slowdown issues after rooting?
3. Do you need to rename CWM.zip to update.zip or do you leave it as is?
4. Lastly, if needed, can custom ROMs be flashed safely, and if so, generally which ones?

1. Permanent
2. No, the same.
3. Leave it as is. Go to stock recovery. Click update zip then choose CMW zip in external sd
where you should put the downloads. After that the recovery will change to touch CMW(use your finger to navigate), it is only temporary, then click INSTALL ZIP and find the rooting zip file you download. Finish you are rooted.
4. After rooting I use mobileodin to flash an ics. But you can flash any ics you want and flash ics kernel speedmod k3-3 to automatically get CMW or flash cf root to get CMW. About custom rom, this i recommend. http://forum.xda-developers.com/showthread.php?t=1716088. You must have speedmod k3-3 before flashing it, very important.
If you want another custom rom read carefully their procedure. Different custom rom different procedure, there are not the same. Be carefull, for example if you want to flash paranoid rom you must be in gingerbread rom before flashing it, if not, you will BRICK your phone. The cm9 is the same, you must be in gingerbread. Just read and again and again untill you know what you are doing, if not sure, read the threads, learn from their mistakes, ask question there, they will help you.
Success! I did it but only CWM.zip got installed from the ext SD card. I had to install SuperSU from the internal SD card. Now I'm gonna use MobileOdin to flash speedmod k3-3.

[Q] Flashing Custom Roms

I have just Rooted my phone using Super One Click. That's it.
Now can I directly flash custom ROM's?
In this thread, I have gotten totally confused with so many things to do and different firmwares.
Please help me out.
Thanks alot
P.S - I already own an Xperia Arc so I do know about different Kernel's and flashing and other stuff. Just a noob in Samsung stuff
If you're on Froyo , you need to flash a GB ROM first
"As a friend, just....put an end to me." - Ventus
Yea, It's already on GB
You have to flash ClockworkMod Recovery.
After you flash it, test it by powering up your phone, keep pressing the home button until you get to a black screen with blue letters(Or Orange like in my nook color)

If you see that screen, CWM has been installed (either version 4 or 5).
Then you go and flash a new ROM.
Go to our Android Development Forums in the Galaxy Ace Subforum, and look for a good rom! Almost every post contains the method of installation.
ALSO WARNING: KEEP IN YOUR SD CARD AT LEAST ONE BACKUP/WORKING ROM. You never know.
(To backup, go to CWM Recovery mode, there's an option there)
Thanks, But how do I flash/install CWM?
I do know how to handle ROM's and other stuff. But since I'm origianlly from Sony Xperia Arc. What I did was, Root, Unlock bootloader once. And then all I have to do is flash a compatible kernel, then a rom.
Over here, I cant understand which order is what and how do I go about doing it. I have rooted... coz i thot that was obviously a necessity.

And I did quote the link in my original post :\
1. if you have froyo on your galaxy ace, please flash a stock gingerbread(official one) first, flash using software named ODIN. you can find tutorial on dev section
2. galaxy ace doesnt need boot loader unlock, it been factory unlocked
3. before installing any custom rom, you need a CWM/similiar type of recovery, you can find em in development section
4. usually, custom rom for sga come with custom kernel too, no need to flash custom kernel first, again, you can find custom room in dev section.but, you can flash custom kernel after flasing custom ROM
I know....this will make you confuse, i mean.....flasing custom ROM for SE phone is pain in the as* for n00bs, but flasing custom ROM for galaxy ace is more "n00b friendly", for ex : you dont need to worry about unlocking boot loader, incorrect baseband, download PC companion(<=damn app that make me headache for 2 hours).....
just flash, and enjoy.....

1. You need update Rom GingerBread 2.3 from Odin.
2. Install CWM recovery 5. (Download, push sd card > turn off > push Power + Home > intall from sd card > chossen CWM Recovery 5 > Yes and reboot)
3. Download rom you like, push sd card, full wide, and install from sd card.
You do not need root to flashing ROMs, only the CWM

Also, i did installed custom rom before but it did go beyond the first screen.

Yep, Xperia devices need different kernels, and recovery is always bundled in kernel. While Mini doesn't, kernel is different part from recovery.
I suggest you flashing it CM7.2 by Mebitek since CM7.2 New Experience have some booting bugs. Firmware is doesn't matter, it's not like Xperia devices.
I suggest you flash unofficial cm7
Democrazy
Mebitek
MIUI GB
or Honeycream
Etc
All for galaxy mini

[Q] Bootloader unlock allowed: no. how to unlock?

Hello guys, I know that there are similar threads and I'm sorry for posting, but I have some specific questions. Having the phone for over two months, I want to try some custom roms.
However in service menu says that the bootloader cannot be unlocked, and I really frustrated. My previous phone was xperia mini and I used to change roms every week!
Anyway, I have done some research and found that some guys managed to change the status from no to yes. One flashed a relock. Ftf. An other flashed some kind of custom stock stock Rom.
But I'm not willing to risk my device by testing those methods. What do you think? Is there any workaround?
I'm running a pre rooted lollipop rom.
Please help!
cmon! guys, help a little!
You can't unlock it. You can only flash custom ROMs which use a stock kernel, so things like CyanogenMod are out.

What if I try using any method? Will it brick?
It can't be done, if it says no that's it I'm afraid. Sony have it locked down pretty well. Only way to get that to a yes is change your device to one that says bootloader unlock allowed YES.

You need to unlock your device (to get it work on other carriers), then reclaim to Sony. Full instructions here: http://www.htcmania.com/showthread.php?t=779828 (Spanish forum).

You bootloader just can not be unlocked mate. Try trading your device out for a different one which allows unlocking bootloader or just install ROMs that don't require custom kernels. I'd recommend this ROM:

You can't install custom roms on locked bootloader. You can't unlock your bootloader if in status it says unlock not allowed, which means your bootloader is encrypted. This happens if you bought either a carrier branded device or the one made for a specific market, such as Malaysia. Some governments require OEMs to close down their bootloaders forever.
In theory, it is possible to hijack one of init scripts and redirect it to load a custom rom, but you can't change or modify kernel, which means that once the OEM abandons your device, as it happened with Z1-Z3, you won't be getting any security updates... . The last time it was done (hijacking init script) was on Xperia ION. To have custom roms, you need to get another device...
Mine did say bootloader cant be unlocked. I had bad battery so I gave it to service and service did change battery, and they did install stock rom because I had flashed phone. And phone came with unlocked bootloader yes so I did unlock it official way. I didnt find any good 7.0 update and I locked it back via flashtool. So think before you try to do it, you cant use PC-Companion after you unlock bootloader.
