Right you think its useless? Or that you cant flash a custom rom with flashtool?
Sent from my LT22i using xda app-developers app

It's not useless at all, but it's useless here. For a custom Rom you need to unlock boot loader which will definitely void warranty. Be safe man.
Sent from Xperia P, using tapatalk.

download an official jb firmware for your phone! download flashtool! enable usb debugging and connect your phone to the pc! Then choose the file you have downloaded and flash it!

You can also use SUS (Sony Update Service)......BTW did you use pcc to install it or downloaded it OTA.....
Sent from Space!

Try SUS/PCC like a lot here are saying. Hope your Internet connection is enough. God knows I tried via official methods but ended up downloading a generic ftf and flashing it.

Slight correction needed IMO: You need to unlock your BL only when your CUSTOM ROM needs a CUSTOM KERNEL.

He can try to repair phone with pcc or he can unlock bootloader and install STOCK or Custom Rom, who says that flashtool is only for custom roms , With unlocked boot loader he will void warranty.. yes.. a part that... he can lock the bootloader again..and I have not seen written anywhere in his topic question that he does not want to lose warranty... so mine it was just a suggestion... not an Obligation
Take care friend

anyways. My xperia P hasn't got any official update. and i am also waitng for official update rather than a manual update, I know the flashtool method is not a risky one but still you may get some problems in using jellybean. Becase the generic version and your S.I version would not be the same. my S.I = 1261-4989 ,
I have heard many bugs in jellybean, Album issue, white screen in contact and messaging, blutooth broblem, fast drain battery prob, slow charging, lagging, etc i wants to know, are these bugs are real or just a wrong imagination. Thanks

I havent seen any bugs so far for JB on xGO. And it performs quite nicely without having to edit build.prop or run init.d scripts. I'm using CE ftf.
Let's go, xGO! To the Jelly Cave!
JB stock, locked, and rooted.

Agreed with senior. Drivers might not be installed properly, or flashing wrong files. Make sure X10 Brand name exists in flashtool alright.

Bootloader have two types: Locked Bootloader and Unlocked Bootloader. Normally Developers will provide 2 version of ROMs to be flashed. Safest flashing for Locked Bootloader is via Xrecovery, while Unlocked Bootloader is Flash FTF Kernel and recommended Recovery. You can check/identify your Bootloader Status and also Simlock Certificate (see whether Suitable to be unlocked bootloader) via S1tool by senior 9luka5
link for S1tool here For more tutorial, you can visit my signature links for PDf guides. Thank you. Cheers

Download the latest version of flashtool v0.9... I think u can unlock bootloader by going to "plugins" tab right next to help....it would show up only if your bootloader is locked... once you unlock then you can flash any kernel you want... remember to backup your existing ROM using recovery before you go around messing with phone

Before I can give you any link I have small question... is your phone rooted? And what version of android you r running ? And if its a custom ROM then what ROM are you using?
BTW you can't flash custom kernel without unlocking bootloader.. you need to unlock bootloader to flash kernel... kernels are usually ftf files you can download them and flash using flashtool.... different ROMs have different kernel so you need to read instructions on ROM thread you r interested in...

You have soft bricked your phone.. don't worry, download a ROM which you can use for locked bootloader and follow the steps and you should be good to go... to get into flash mode try this.... don't connect your phone but start Seus-> update software-> repair-> software will ask you to get into flash mode so turn off phone by removing battery, connect the phone without battery-> place the battery while holding the back button down and phone will get into flash mode and stock ROM will be flashed...

[SOLVED] PCC update fail, SUS crashes, Stuck at Sony Logo when boots!!!

I have a problem here. I was using nightelf oc kernel with JJ hybrid rom before. Then i decided to switch to KA21.1 latest.
Earlier i had tried to install KA18 and KA19 on my device but dont know why i faced some bugs so i quit it.
To install KA21.1 I first decided to install Official ICS 4.0.4. as a necessity to install KA21.1 device must have any 4.0.4 rom.
I flashed 4.0.4 using flashtool.
then I tried to install superuser. but got errors. I googled the issue and found the solution to install SU and CWM in latest 4.0.4 here .
after that i tried to flash KA21.1 in recovery mod. It was successfully installed and asked to reboot. After reboot device stucked at the Sony logo.
I re-tried the whole procedure from the beginning hoping I must have done some mistake. But the result was as it was.
Then I tried to repair my phone and update it through PCC. But at the end of its second step (2. Prepare), I got en error " Installation error - Unable to install or start phone software update components."
I again googled the problem and saw that SUS was helpful for some people who faced same problem. Then I tried SUS too. But It was also waste. SUS crashes after asking me to select my device.
Please Help. I just wanted to go for an light and fast rom.
Any suggestions/help is welcome. i wanted my phone working again.
Rooted.

Not really. Only problem he would have is that pcc/seus would refuse to update his phone, with excuse of modified software.
Unfortunately he didn't even came to that step, as pcc had problems with updating components. Common problem with pcc, will be solved in a few days, or even on the same day.

1) depends how you unlocked your BL.
If official, then it won't work, if unofficial, then it will work but..
2) reinstall of pcc won't help because its not problem in your installation, but in connection to Sony's servers. But no harm in trying
But you do need to reinstall seus as you said it crashed even when selecting device (you mean from phone list?).

yea! it crashes automatically after i choose my phone from the list. and i have unlocked BL official way. But locked it using this. It says re-locking this way can redeem back warranty and also will be able to update using PCC/SUS.

you already had an unlocked bootloader so why didn't you install a compatible ics 4.0.4 kernel with root and cwm. After that flash sonys 4.0.4 ics via ftf file and you are done. You got you base to install that ka21.1 rom. That doesn't work?

There is not any "sin" in doing this. I have tried this many times. The thing is that whenever someone gets its phone stuck somewhere, he tries everything to get back his phone in working condition. I have even updated my phone using sus with "unlocked" bootloader !!!

Download pc companion or sony update service, click in sus on your phone, reinstall/repair firmware (something like that) and then you just have to plug your phone in flashmode again. It will flash the firmware (guess it will wipe data) and it should be fine
I've got the same problem as you. just download firmware for your device (search in google), then flash via flashtool.

i am in Greece.. if i flash it with the stock ICS 6.1.1.C.1.0 file which i found here and it's from T-mobile Croatia, i think that my sim will not work..
My XU is simlocked with Orange - Poland and works great with any region ROM (sometimes GPS needs fixing). Have you tried ADB restore root method from Flashtool? For some reason bin4ry never works for me, but Flashtool one (isn't it the same script?) always works.

Here's a concise set of instruction. I'm just reposting the link.
http://forum.xda-developers.com/showpost.php?p=35061620&postcount=49
I've managed to root it.
1. Flash b.1.0 kernel
2. Root with flashtool
3. Flash c.1.0 kernel

XU dillema

Hello. This is my first post here so forgive me if i done or post it wrong.
In short i have updated phone from gb 6.0.B.1.564 to Ics 6.1.1.C.1.0 via pcc and it is from then acting very poorly in comparison to before, very laggy and slow in general. What id like to know now is what is best to do? I have heard there is some new latest firmware released for xu ics, is it possible for me to get that, and is it improved a bit performance? If nothing, can someone pls point me how to downgrade back to gb, or maybe suggest something else? Just so you know, my phone is not rooted and it has locked bootloader.
Thank you all in advance

Hi zig , firstly I will not suggest u to downgrade ur phone secondly do one thing to make ur phone processing faster.... Go to settings>apps>all> click the app and on the top right u will see an option ''disable'' , disable the preinstalled apps which u don't use like ''Google +,email,gmail,talk,fb,office suite,top contacts,retail demo, recommender,maps ,Google chrome,exchange services'' restart ur phone and then use..... Let me know how is it working.
Yea there is one more new update of Xperia u and that new ICS 6.1.1.B.1.54 version is good....it's bug free ,I would like u to upgrade it.

Hey tyvm for a quick answer. I have done what you told me, except ofc the ones i use and exchange services, cos i dont know what it is, but im guessing its for incoming mails or messages maybe. It improved a bit, but it is still kinda laggy. The thing that is worrying me is a battery draining, it goes down rly fast. I know about the update you mentioned, but there seems to be even more new then that 6.1.1.b1.100. In any case how can i upgrade to those, be it new or older firmware? They are not listed in pcc, it sais its up to date with this last one i did. Thank you again for help.

To get a real lag reduction and battery drain issue, I suggest you to root atleast (without unlocking your boot loader which does not void your warranty).
For that you need flashtools from there
http://forum.xda-developers.com/showthread.php?t=1933985
However, B.1.100 is slightly better than the previous version
So to try that, flash it with flashtools, you can find the download link here
http://forum.xda-developers.com/showthread.php?t=1974430
You do not require root to flash Sony stock ROMs.
Another better alternative is to flash custom ROMs for locked bootloader,
My personal suggest, go for SlimCM ROM, pretty stable and snappier.

So in essence i can flash newest stock B.1.100 without root, and not losing the waranty (subquestion only unlocking the bootloader voids waranty, but root no? I am asking this cos i do seem to remember but i might be wrong that root can also void it, and i wanna be sure . But if i decide to go for custom ROM which you suggested do i need root for that? With root i can remove loads of stuff which i cannot do now, so thats why the lag is much lesser?

Yes you can attain root access without unlocking your boot loader.
Use flashtool method or Bin4ry's method.
Again yes, you can flash SONY STOCK fw using flashtools (without root or unlocking) in flashmode (just keep in mind to "exclude TA")
Once you are rooted you can install apps such as greenify that really helps to last the battery longer.
Also you could remove the bloatware and other useless apps.
Or you even you can make choices to install Custom ROMs for locked bootloaders. Just check the development section.
This is my personal suggest: SlimCM ROM.
Though its CM9
http://forum.xda-developers.com/showthread.php?t=2143750
See the instructions for locked boot loaders.

To root fw C.1.0 or any later versions, you need to
-flash the kernel alone of B.1.0.
-follow root procedure by flashtool or Bin4ry method.
-Then flash back the corresponding kernel of the ROM.
Done

Ty for all the suggestions. I rly appreciate it. Think i will go for what u suggested first, slimCM. I checked it and it looks nice.. Althou some things are not so clear to me. In both instructions, for slimCM and in patch for locked bootloader it says wipe data or factory reset in recovery. What is recovery? And it also mentions to do the backup of my current ROM. How shall i do that. Wipe data and factory reset means all data gone from phone so i should backup at least photos, music and sms-es to my pc or some app.

That's where you can find recovery:
http://forum.xda-developers.com/showthread.php?t=2020897
CWM recovery is required to flash custom ROMs or MODs etc.
You can find the wipe data, cache options in the recovery menu. Just back up your contacts, messages and things.
Nothing from SD card will be lost.
Do carefully patch the ROM as per the instructions to make it into locked bootloader.
Copy that zip file in SD card and enter CWM recovery
-flash ROM
Done !

heyyy
U can root ur device with out touching bootloader dats pretty easier....
but remember after rooting u need to install cwm recovery bcz its used to flash custom roms and rem u can also take take backup of ur entire rom
if anything goes wrong during flashing custom u can easily restore ur device to normal..... by using back up....
flash b.1.10 rom bcz it can be easily rooted by using flashtool......
So finally the process is root first, second recovery and finally flashing rom of ur choice.....
There are so many ROMS in dev section for locked bootloader......
njoyyyyyyyyy............
I ll attach CWM recovery files download and extract.... In the extract folder double click install(.bat file) make sure device connected with debugging mode on..... accept all superuser request on device........aft rooting u ll get super user app in apptry
PM if any difficulty

Thank you all from the first to the last for all the suggestions and help. The XDA is awesome, and full of helpfull people. I will post how did it go with all the rooting and recovery and ROM Cheers again

So i have backed up all the data (music, photos etc) on the pc. Tomorrow i will get on doing what you guys suggested. So to get it all confirmed, first do the root with flashtool, checkin superuser and rootme, and then i will be rooted. Then cwm recovery install, then applying the patch for locked bootloader for slimCM ROM, then i go back in cwm, make backup of current ROM and then wipe data, and then flash the rom.. That be the order? Is there any thing i should take special care of?

I had a little problems. It wouldnt let me install the flashtool drivers. Probably cos i was doing it on laptop on win8. Will try it at home on win7.

Remember install flashtool while your anti-virus is disable...!
Sent from my ST25i using xda app-developers app
I did that. But what i wanted to say i get error during the instalation of drivers. Flashtool alone was installed corectly.
Sent from my ST25i using xda app-developers app
It will be lot better if you try it with Win 7 as Win 8 + Flashtool drivers don't go well together as 8 allows only signed drivers to get installed.
Though there's a thread on how to install Flashtool drivers on win 8.
Sent from my Xperia U using xda app-developers app
Hello all. I managed to install drivers. The fix for win8 worked. I started root in flashtool, done all that i was told to but it isnt rooted. Log says Root hack did not work. Any ideas? Cheers again for all the help

Here's the Rooting Process for you.
This Rooting guide applies to all FW versions above B.1.10. (i.e. B.1.54/C.1.0/B.1.75/B.1.189/B.1.100)
1) Open Flashtool.
2) Click the Flash icon.
3) Select Flash Mode. (Make sure USB Debugging is ON in your Mobile Settings before connecting to PC)
4) Select & Flash the B.1.10 kernel. Then Reboot.
5) Select the Un-Lock icon and choose your preferred SU app & proceed.
6) Follow the on-screen instructions.
7) Now you have rooted your device.
8) Flash the kernel of your respective FW from the FTF file through Flash Mode and let the device reboot.
