do I lose warranty if I install a custom recovery + root with z4root + flash a custom rom on Optimus One?
thanks
Yes.
But you still can try flash back the official ROM before you send it back.
If no success then goodbye warranty (If they see it ofcourse).
Cheers
so there are no bootloader unlock to do?
[for example, I did bootloader unlock on my Nexus One (my phone... Optimus One is my girlfriend's phone)]
no news...?
You've already got your answer. Don't know what you want more.

I did another question mate...
so, can sombody confirm that the procedure to install a custom rom is the following:
- install a custom recovery
- root with z4
- install a custom rom
anything else to do? (no unlock procedure as for nexusOne?)
Second question:
wich is the procedure to flash back original recovery and original rom in case i flash something custom (recovery or rom or both)?
thanks mates
No, its all what you need for Custom ROM. Maybe - for unroot you need FW V10a(b,c) not higher.

Hi,
In case anyone (like me) has issues installing the S1boot driver for your xperia, to be able to flash other firmware, here is the link :
http://forum.xda-developers.com/attachment.php?attachmentid=718060&d=1315877046
This driver will install itself after you run the executable file dpinst.exe after having extracted the archive.
With the driver you can use the flash tool (combined with your phone booted in flash mode (volume down + usb connect)) to flash other firmware on the phone.
P.S. i'm not talking about fastboot mode, but "flash mode" ;-)

i dont think you have to unlock the bootloader to flash your phone, you have to enable usb debugging in your phone ,settings>applications>development>usb debugging
pls correct me if im wrong
Hi,
As far as I know you "have" to unlock the bootloader before being able to flash custom firmware on the Phone.
I unlocked the bootloader via the sonyericsson site link :
http://unlockbootloader.sonyericsson.com/
I use 4pda.ru firmware+kernel from this thread :
http://forum.xda-developers.com/showthread.php?t=1424121
Reason I dont use CM or MIUI is that I need a 100% functional phone (both corporate and private usage, that's why) . I encourage the development on CM and MIUI, don't get me wrong here
You can find more information about unlocking, rooting and flashing custom kernels and firmware on this XDA forum.

how about flashing through CWM recovery like the previous xperia? is it any different? because before the msm7227 and qsd8250 bootloader been unlocked, people use CWM recovery to flash rite?

You can setup CWM and flash ROM on unlocked device, but you can't flash kernel and baseband.
So current situation is: you can't flash CM or MIUI (which requires their own kernels) on unlocked device, but you can flash stock-based mods like repack4pda (which works with stock kernels).

Hi!
I am new to rooting and flashing on Android. I have an Xperia S which is currently in repair for yellow tint/spots on the screen. When I get it back and know that it is working i will unlock the bootloader using the official method.
My goal is to have rooted gingerbread on the phone, maybe with a better kernel. I have found a prerooted ftf with the FW that I want. Can I just flash that one and it will work?
Do I have to install custom recovery?
Thanks in advance!
Have I understood it right? unlocked bootloader + flash prerooted system rom. That should work?
If I want to install custom rom I need custom recovery. I would appreciate if someone could verify this for me, thanks!

Hey guys,I own optimus one and I m used to rooting and stuff but my brother owns xperia mini pro so I need to install cyanogenmod (9 or10) whichever is stable.I had gone through various guides and stickies yet I want to be dead sure that I don't mess up my brothers handset. Its kinda new coz bootloader needs to be unlocked and also kernel image needed to be flashed separately unlike in optimus one.
Now I want help of you guys in the following manner like:-
1. My brothers mini pro is on ICS 4.1.B.0.587 and the rooting tutorial provided here for the said firmware
http://talk.sonymobile.com/thread/41119?start=0&tstart=0 is not clear to me coz it says that first I need to install some kernel [only mini mentioned here] then next I need to flash another kernel according to firmware. Can someone explain what is being done in this and why rooting is so complicated in this.
2. Certain ROM's say that you need to flash kernel first using flashtool
My query is that all ROM's that I flashed till now on optimus one included kernel and I only needed to flash ROM zip through cwm.. So do I need to flash kernel everytime I flash ROM!! and isn't there flashable zip for kernel too!!
3. FXP ROM's do not contain things like what's working and what's not, it only has issue tracker so it become difficult for new comer to know the bugs in ROM. Can anyone tell me the least bugs cm9 & cm10 ROM and what are the bugs present.
4. Lastly, should I proceed like this!!
i. Root device (though method isn't clear to me)
ii. unlock bootloader
iii. install cwm (I guess I can do this using flashtool)
iv. backup current ROM along with kernel (for future use,I know its optional)
v. flash kernel using flashtool
vi. flash ROM through cwm.
I m a quick learner and I just need some guidance on this new device (double checking coz its my bro's device) . Looking forward for support. Thanks

You needn't root first if you want to unlock bl, just unlock bl and flash a custom kernel (in most custom kernels cwm is included).
Backup your rom and install the rom...
hmmm....
1. Unlock Bootloader........
2. Flash Custom Kernel (all custom kernel is per-rooted and have CWM).......
3. Boot into CWM and Flash CM9 or CM10 (factory format/wipe dalvik/cache).....
4. Boot into Fastboot And Flash FXP kernel for CM9 or CM10.....
xperia phones aren't like sammy, lg or htc where recovery is a separate partition from kernel. in fact, by default xperia phones doesn't even have "stock recovery" like on other phone. by that we integrate cwm in kernel ramdisk.
and to answer the question:
1- flash custom kernel mean't for your phone only, never ever flash kernel intended for other phone. and its done via fastboot and should be flashed before flashing rom.
2- like i said u can't compare xperia phone with other phone like sammy etc, its different. kernel must be flash via fastboot.
3- for cm10, bugs that i notice is slow accelerator, but fixable with some text editing, and non working front camera for lww and minipro.
4- should be like this, according to order:
- unlock bootloader.
- flash kernel via fastboot.
- boot into cwm.
- backup rom if u want.
- wipe data, cache and dalvik cache. don't wipe system partition or u will get error when flashing rom later.
- flash rom, and gapps if its cm/aokp/pa rom.
- profit :good:
thank you guys.... this made me clear...
one last thing :- which kernel should I flash on stock 4.1.B.0.587 which is pre rooted and have cwm after unlocking bootloader.I mean the one compatible with above firmware and also do I need to do anything with baseband or will it be compatible. After this m ready to enter the custom xperia world
Remember to backup your stock rom before unlocking the bootloader as everything will be wiped clear.

No, i just meant that backup up your contacts, messages, apps (can be done through astro file manager) etc, before unlocking your bootloader because unlocking will wipe your data.

I would like to run custom ROMs( CM) based in my device. To start with, I aj a total noob and my device currently runs stock ICS provided by sony itself. It's not rooted. I wanted to know the steps regarding how-to do the procedures like :
~> unlock bootloader ( is it needed or not)
~>root (needed or not)
~> flash custom ROM( which one is good and runs fast,least buggy)
~> which CM?
~> which recovery, which kernel, how-to's
Etc.
I don't know if all info is available on the forum in one thread or not, so I created a new thread.
Thanks in advance.
AW: Help regarding Sola Custom ROMs
You have to try every ROM on your own! Everybody has an other way to use it's Smartphone, so nobody can say which ROM is perfect for you and Root and CWM is needed for every Custom ROM Cause you need CWM to install the ROM and to install CWM you need Root And if the ROM is compatible with a locked or unlocked BL is said in every OP of a Custom ROM
Open your eyes and use the search function! You can find nearly EVERYTHING here on xda
But still a guide would be helpful...if possible...

If you don't wanna unlock your bootloader(which will void your warranty) but you wanna install cwm, you can always root your phone and install the cwm recovery... Now, every custom roms is very good!!! You must be thankful to all the devs here and try some roms on yourself... We can't tell that which Rom is good for you so you must try it on your own... CyanogenMod 9 is good and very smooth but requires you to unlock your bootloader... You also must unlock your bootloader to flash awesome kernels that provides overclock and many more...
You can find cwm recovery for locked bootloader at here!! Be sure to follow the steps properly!!
And to root stock .54, you must first flash the .10 kernel using flashtool, root it using binary method, then flash back the .54 kernel..
Hello
I have a few questions about the hole "thing" cause this is my first android phone and on apple there was just the option jailbreaked or not jailbreaked
My first question is about the bootloader.
since i was reading the thread "[FULL ROOT] Community RootKit! (ASEC vulnerability) {v01} [20140615]" i am asking me why should i unlock my bootloader when im able to get root without doing this?
Is there any special point for wich i need the unlocked bootloader or is it just written for the people who unlocked there bootloader already?
Then to second question is about the sequence.
Am i right when i
1. get root
2. install cwm or twrp
3. install custom rom?
by the way: is there any huge difference between twrp and cwm? because at the table "Kernels" there is the TWRP for the Xperia T2 Ultra and an unofficial version and from CMW is an unofficial version too? Wich should i use?
and my last question is should i wait for version 2 of the RootKit or are there just small differences?

Bootloader unlock is required to install Custom kernels like DOOMLORDS kernel. In case if you dont want that then no need to unlock BL.
Just follow this post http://forum.xda-developers.com/showthread.php?t=2784757 to get root on Locked Bl and then revert back to .402

A custom ROM is different from a custom kernel. Some custom ROMs do not require custom kernels (because they use stock kernel), but others do. So it really depends on the custom ROM that you want to use. Instructions and requirements will be posted in the respective ROM thread.
But if you want to use a custom kernel, then you will need to unlock the bootloader first.
And obviously, if you want to flash a custom ROM that needs custom kernel, then you will have to unlock your bootloader first.
Even if you want to flash a custom ROM that does not require a custom kernel, you need to first root the phone with the RootKit. Because flashing custom ROMs is usually done via recovery, and recovery installation requires root.
Hope the above is not too confusing.

So just to be sure.
I Run the toolkit for root
Then i take twrp or cwm
And then i flash a custom Rom wich use stock kernel
And that can i do with a locked bootloader?
What can be different in an other kernel?

Yes, run Rootkit, install recovery (TWRP/CWM) and then you can flash custom ROM which uses stock kernel.
Custom kernels allow functions such as overclocking, undervolting, etc.

then i have 2 new questions
1. How can i downgrade my phone ? just download the fw and use flashtool?
got an iphone till now and there it was a hard work to do it ..
2. is there any difference between locked and uinlocked bootloader? i mean in the point of restoring so that i have my warranty back?
1. There's now an even easier way to root the 402 firmware that does not require you to downgrade first:
http://forum.xda-developers.com/showthread.php?t=2784900
But note this post, where you have to change something in the install.bat file for it to work on the Z2:
http://forum.xda-developers.com/showpost.php?p=53480221&postcount=81
2. It's a little more work if your bootloader is unlocked and you want to relock it before sending it to the service centre. You need to have your TA backup before doing so. If your bootloader is locked, you just have to remove root via SuperSU before sending it in for service.
