Hi,

I saw that with flashtool it is possible to edit a file. Is it also possible to replace a file?

Example: Recently I had the problem that I changed a file and when my phone rebooted I saw the Sony and than the Xperia logo then the phone stared again with the Sony logo and so on. I forgot to tell that I made a backup of the file but I couldn't replace the file so I made a fresh install.

Is it possible to replace files in flashmode?

thanks

hi

im to unlock my SE X8 bootloader

ive readed! from a persian forum :

you have to install 'ggsetup-2.2.0.10.exe' from 'flash tools/driver' before using 's1tool' and/or flashtool to unlock !

ive rooted my x8 some days ago and installed gdx25 and after that restored my stock rom backup so the x8 softbricked

so ive installed "pc companion" and repaired my x8 some days ago and now my x8 is lock and unroot

i never unlocked before

1. am i need realy install that file 'ggsetup-2.2.0.10.exe' or 'pc companion' was enough ?

2. am i need to root before using 's1tool' and/or 'flashtool' to unlock ?

Hey can i use this flash tool to unlock the bootloader of x10i????

I rooted the phone using flash tool v0.2.9.1. I can not reboot into recovery using rom-toolbox or rom-manager. I could reboot phone in recovery through flashtool only. Is it due to unlocked bootloader or something else???? I am having xperia x10i.

Edit:-I unlocked the bootloader of the phone with help of above method. But i am not able to access CWM recovery through phone. It reboots in recovery with flashtool only. If someone help me with it.

Does anyone have any idea on this:

My phone (Xperia Tipo ST21i) can't get past the "Xperia" bootscreen, therefore, I cannot allow any accesses on my phone screen + since the Tipo doesn't have any tangibly "back" button, I simply cannot follow the Flashtool's instructions.

Now, the phone gets recongnized by Flashtool, though it won't get recongnized by PC Companion.

So practically, because I made 1 fail in the /system files, there's no way to boot my device, and apparently also no way to fix it...

Does anyone have any tips on this for me?
[XPERIA X10 Q&A, Help & Troubleshooting] Toledo_JAB:
For some Xperias use the volume down button in place of back. Works on my ion.

I Don't know if anyone here will be able to help me, but I seemed to have bricked my phone, forgeting to install a kernel for a rom, and now i can't get past the sony ericsson screen, i had xrecovery, but i can't get into that, i tried to use flashtool, to flash it(though i have no idea what i'm doing) but i get this error if i wait until flash tool prompts me to put the phone in flash mode

on the phone the light turns green for a few seconds, and then the phone restarts, locking at the SE screen again, further more this is what happens if i put the phone in flash mode BEFORE i select flash and flash mode on flash tool

the device lights up green, flash tool shows a progress bar then the green light goes out, 2-3 secs before flashtool says "ending flash session" and so on

Any ideas would be helpful, i did try to install the drivers, and didn't seem to encounter any problems, i already tried SEUS, AND PCC both of them tell me there are no updates available, i tried to "repair" in PCC, and i seen on another forum post that you could repair in SEUS, but that seems to be gone in the newer versions i guess..

If it's showing No :

You'll have to use s2 tool

And that is a paid software ....

You can use to unlock bootloader by s2tool for free

What you actually pay for,is to unlock your SIMlock!

In short,use s2tool to unlock bl !

'x10a'. i want to upgrade it to 2.3. pls i need

your help in order to download the

appropriate firmware. a download link of appropriate firmware. thank u
[XPERIA X10 Q&A, Help & Troubleshooting] Toledo_JAB:
The X10 has two versions X10a &X10i. The only difference is the cellular bands used. The Rom can put anything in the settings/about, the X10S Rom shows X10S. Roms can be used on neither version. There is a thread in the X10 general section that has links to the stock firmwares.

plsss I really need your help. when ever im trying to connect my x10i in to flashmode through flashtool, the phone boot automatically after the green light is on. also, when charging my phone, though its off but boot automatically.

Let it switch off and then after a while try connecting in flash mode!

You could try a fresh flash of a custom Rom, maybe Rom bug?

Or try installing flashtool properly again!
