XPERIA X8 boot problem

I installed ICS on my XPERIA X8 and it freezes at boot. And I cannot go to recovery mode, where is my backup. I know I need to use FlashTool but I don't know how to use it, because it says:
03/021/2012 15:21:18 - INFO - <- This level is successfully initialized

03/021/2012 15:21:53 - INFO - Device disconnected
And I cannot flash the original image.
Hot to connect the phone?
With " Press and hold back button then plug in the usb cable"?
Now I can flash it but it isn't reboot just say device disconnected, then device connected in flash mode, then device disconnected, then flashing aborted

nearly the same problem here trying to unlock the bootloader on my E15i.
Would appreciate if anyone has a suggestion how to overcome this.Thanks

Try this

IF you have stock ROM for X8, you can flash with flash tool..
the first, hold volume down in your phone and plug usb kabel to computer..
see your phone have green light, its flash mode.. )
and then go to flash tool, and all its works..

.
Thread moved to Q&A due to it being a question. Would advise you to read forum rules and post in correct section.
Failure to comply with forum rules will result in an infraction and/or ban depending on severity of rule break.

What?! First of all - not volume down but BACK button.
In flashtool directory You will have drivers folder. Install those drivers. Then reboot Your PC. Copy Your firmware package into firmwares in flashtool directory (.ftf files). Than run flashtool, click on flash, choose the package, click ok, flashtool will aks You to connect Your phone in flash mode. Plug USB cable into PC. Plug in USB cable into phone and while doing this You must hold back button. And flashtool should recognize Your device and start flashing.

Thank you! You saved my phone's life!
I'm trying GingerDX now, and I making an ''XPERIA X8 MEGAPACK''

Anyway, I do not know why this is:
When I first installed gingerDX i have installed many apps. And when I'll removed this backup, and I installed this rom again, the phone freezes at the boot screen.
(I know how to do it. I flashed the stock rom from my backup, and It is working. But I cannot make a backup from this rom

Because You should do a full wipe When You install ROM again there are some files from old one. And this may cause boot problem

Hi, I've tried this but it doesn't work. My phone just keeps rebooting itself after SE logo animation is done. What can i do?

Boot prroblem ICS
I've tried ICS for stock kernel, but it isn't boot! But i want to try it!

Dude... just flash a stock SE rom via Flashtool and its done

Generally speaking, bootloops imply you are missing the x15 Baseband required for custom ROMs to work: Follow the mediafire link in B.Jay's profile and find the x15 Baseband corresponding to your X8 version (It's in the sticker under the battery)... Hope this helps.
EDIT: Update your FlashTool Version!!!! http://androxyde.github.com/Flashtool/

Its better to make a new thread...
You should attach in flash mode first then select and install drivers, now open flash tools app
If still flash tools doesn't recognize use Gordon's gate PC app to reset drivers,(this app is in your flash tools folder / drivers)

Keep volumm down and connect your phone to computer >> open PC companion >> click on Support Zone >> Click on Phone Software update >> Click Repair >> Wait till it done . Try it's . Good luck .

the best method is download SONY UPDATE SERVICE software to your pc. after installing update service, turnoff your mobile then press and hold the volume down key , and connect it with your pc. (even if your phone is not charged no problem ). release the volume down key when the on screen instruction says it. after that if the system says your phone has latest software, then select reinstall the software. wait until it finish. thats all.

dont do too more
just power off ur sp bu stick the reset button in the backcover,and power on,see what happen,take it easy and carefully

[Q] Xperia SP bricked

Hey
I just read that I could get the update by editing the build.prop file
So I copied the build.prop file someone posted in another thread, and rebooted.
File Source: http://dl.xda-developers.com/attach...4f75e54/52fa6db5/2/5/7/2/9/4/6/build.prop.zip
Now, the phone's not booting at all. The "Xperia" screen comes, and it tries to reboot, and this keeps on happening.
It's a rooted C5302 with locked bootloader

here are the flashtool logs. It's trying to reboot after every unsuccessful boot

turn off your phone by holding volume up + power until 3 vibrations...then flash whatever you want by flashtool..

I'm downloading the .254 firmware right now, as I don't see any .ftf uploads for C5302.
But I don't know if it will work, I mean, It's constantly rebooting, even in flashmode.
Edit: After the first unsuccessful attempt to boot into flashmode, it seems to be automatically rebooting in normal mode, and not flashmode.

There's no way I can flash the stock firmware.

Isn't there anyone who could help me out?

Umm... you should probably get a new phone or flash a custom rom. If that doesnt work then you REALLY need a new phone. Besides, your warranty is gone :/

I guess u still have ur warranty, cause u have not unlocked boot loader..take it to Sony service center.don't mention anything about root.

He doesnt have warranty. He flashed custom roms, but he could get it back if he did reset his flash counter though.

Mate he is specific that he changed build.prop,he cannot flash custom Rom without unlocking bootloader.
P.S : I had this problem but I restored it from CWM restore.he still has chances to get it repaired.

This ain't the samsung forums. If you have fastboot then flash doomkernel to get recovery ( C5303 Ftfs work with C5302 )

Bootloader Status: locked
No custom ROMs ever flashed, just rooted the phone.
Took it to customer care center today, they were like the motherboard is ****ed up.
They've taken it under warranty for now. They're gonna replace the motherboard, they said.
Hope they never find out what actually happened :fingers-crossed: and I get it all covered under warranty

The phone wouldn't boot in any of the modes: Normal, Fastboot, Flashmode.
It would reset/go into bootloop seconds after I boot it into any mode.

Of course fastboot won't work you have a locked bootloader

I've had this issue, it's difficult but I managed, hold the down button for flashmode, press reset button, as soon as you release it plug phone in as fast as you can! Takes me a few tries but it should work unless you did something really really bad

[Q]Flashmode disconnects every minute

Hi,
My Xperia Z1 (C6903) (A.0.757) is being weird with USB connection to the computer. I shutdown my phone and put it in flash mode, then went to grab some FTF files online. When I looked at my phone again, it was at the home screen. So I shut it down again and held the cable to the phone port, but in about a minute or 2 disconnects and reboots into the OS. The weird part is the phone never disconnects in the OS.
Code:

I switched the charger cables and it did the same with flashmode. I switched ports on my computer and I still have the same problem.
Is my USB port damaged? Does flashmode have auto reboot when idling?
I'm afraid it'll disconnect while flashing, that would be death sentence to my phone.

Did it again and I got this:

Notice how it disconnects from flash mode exactly 1 minute.

Have you actually tried flashing something?

No. I was afraid that while flashing it'll cut off and then my phone is unusable. But based off this1 minute cut off time on flashmode, do you still recommend flashing?
This is a new Z1, so I'm not sure if its a defective port or not.

set up the flashing files
wait until flashtool tells you to connect, then connect, it will be fine

It was the same for me. It disconnect after a while. Don't know how long it takes though.
So I prepare the files and w8 for the prompt to connect the phone. That works for me anyway.

Which version flashtool are you using?
I had this issue on an older version.
back then i basically just keep holding the vol down button and proceed flashing.
annoying to do but that was the only way for me.
Didnt have this anymore with the latest version.
