I was following the exact step-by-step guide here:
http://forum.xda-developers.com/showthread.php?t=1196808
and after I flashed the kernel downgrade, unplugged USB, power up the phone and immediately plug in after the vibrate, I never got the message in the next step that says "Connected Device: X10", and the "Root" button on the flash tool never became available.
Now my phone is permanently stuck at the "Sony Ericsson" black screen, it won't even turn off. I checked device manager and there are 2 hardware without any drivers. one of them says "Modem Device on High Definition Audio Bus", and the other says "SM bus controller". Does this have anything to do with my problem?
I'm running Win XP SP3, I tried to let it automatically search for drivers but it didn't find anything. I went to:
http://forum.xda-developers.com/showthread.php?t=1193066
and downloaded those drivers, but have no idea how to use them. Tried to use device manager to look for drivers in the downloaded folder and it doesn't recognize anything.
What now? At this point I don't care if I can still root my x10 or not, I just want to fix it so I can use it again. I tried PC Companion but it won't even recognize my phone, keeps telling me to enable USB when I can't even get past the SE screen.
You should try flashing a new ftf firmware bundle, then try the steps again.
ok finally fixed... had to use a friend's computer who is running win7 and actually automatically installed the drivers. everything went as explained on the guide... I guess the guide is not win xp friendly then
Hi everybody,
I've been searching on forums, tried multiple solutions but nothing helps. Though I'm familiar with all this, I'm just stuck on one point which makes all this unlocking process very frustrating. My phone is a Xperia P (JB) and I went to Sony's dev page in order to unlock the bootloader. Unfortunately, even if my phone is eligible for unlocking, I just cannot pass one of the point: fastboot mode.
Basically, when I power on, vol up, fastboot mode is enabled for a few seconds only (led) then disconnects from my device manager and stays with an amber (orange) led on. I just can't have my phone stay in fastboot mode. Same if I go with the command line adb reboot bootloader...
After looking for this problem on various forums, I've tried to update the drivers to (S1 fastboot) found on multiple posts, didn't help. I thought it was a problem with my PC (Win 7_64) so I tried with a fresh install in 32bits on another disk, didn't help. Tried even with Win 8 64 and 32, no chance... USB debbuging is on.
Is anyone experiencing the same problem or has anyone a solution for this? I'm just getting mad by not being able to unlock it.
Hi! I think that the driver is not properly installed! Another site I found this description to see if it helps!
Install Sony Xperia (P / U / Sola / Go) Driver and fastboot in Windows 7
Sony Xperia Driver Installation
Go to Setting > Development
Check USB Debugging
connect Xperia (P / U / Sola / Go) to PC / laptop
Open device manager
Right Click on SEMC HUSB (it should have a yellow triangle warning)
Then select “Update driver software”
Choose “Browse My computer for driver software”
Choose “let me pick from list of device driver on my computer”
Click “have disk” button
Browse to Xperia_P_Xperia_U_Xperia_sola_drivers extract folder
Select sa0104adb.inf
Approve all confirmation
Click OK
Sony Xperia Fastboot Installation
Turn off Xperia
Open Windows 7 device manager
Press and hold Volume[+] Sony Xperia button
Connect to Pc / Laptop
Right click on yellow triangle warning (device warning)
Choose “Update driver software”
Choose “Browse my computer for driver software”
Choose “Let me pick from a list of device driver on my computer”
click “Have a disk” button
Browse to fastboot driver extract folder
Select android_winusb.inf
Approve all confirmation
Done
Note:
A sign that fastboot connection is success is LED will stay in purple
In fastboot installation, open device manager before connect the device is a trick. A yellow triangle (device warning) only appears around 5 sec
It`s better to restart the windows after driver and fastboot installation

Hi Rajen,
Thanks for your help... I've done all this before, repeated it now step by step but no luck... Cannot have my P to stay with purple light on (fastboot). It still stays purple for 3-4 seconds then amber.
Any other idea?
@swissman you should open device manager on Windows 7 first then connect your phone......when its connected youll see anerror or something sign there and click it then choose install driver from pc......navigate to those drivers and Finish....hope this helped....

Hi! Thank you... I really did that... I think almost 20 times but nothing helps. I think I've done almost everything possible (Imagine, thinking that it might be a 64bits issue and Win 7, I've even tried to downgrade to Win 7 32 and Win 8 32! ..
But nothing helps. It installs correctly the drivers, computer reboot (or even not), replug the phone with Vol up and still getting a 3-4 seconds purple LED and then disconnection. I'm getting mad as I tried almost everything I found on XDA or others but nothing helps.
The only thing I haven't tried yet is to downgrade to ICS, try to unlock the bootloader and upgrade back to JB
Ok, I finally have been able to unlock it. What I did, VM with Windows 7 64, booted in fastboot and updated drivers with "Android ADB Interface" drivers from Google directly (not the one provided with SE modifications)... My phone stays now in fastboot and has been successfully unlocked.
Don't ask me how it did happen, I'm just being happy to have it fully under my control
Anyway thanks guys for your help!
When the purple led doesn't last it means you haven't installed it correctly......the thing we are teaching you is I think, a shortcut method,just in order not to install to many files.......so I recommend installing the whole android SDK if you have time......

Hi!
I had a problem yesterday with my Amoi N828 cell phone. During a contact list or messages searching, my phone was automaticly restarted. My idea was to make a system restore using option available on the power on/off button. After that I saw chinesse menu which is not understoded for me I pressed some button and after that such process was started and stopped during 15 min. My decision was to a phone restart. And right now, during system initialization I'm seeing only Amoi logo and phone is stoped.
My next step was to flash system again. I found some drivers MT6589, additionally firmware and "SP flash tool"
When I'm connecting phone without battery by USB cable to the system (Win7 32 and 64 bit) is detected and looking the drivers. And now is a problem. my device is visible for the moment and after that is disappears and again - see link below:
youtube.com/watch?v=Wg47gdlB7YU
the question is why? When the drivers are installed, the problem is still same like before - nothing changed
PLEASE HELP ME! I'm woeful ((((
Sorry, ive found a similar thread at http://forum.xda-developers.com/showthread.php?t=2820018. So the situation:
1. Download PC Companion and pc companion tells me to update.
2. Download finished, and its asking me to hold back key and plug the usb simultaneously.
3. I know im supposed to wait the green led, but it doesnt stay on, it flashes about 0.1 sec then turns off.
4. It then showed SE logo and showed the battery charging.
5. Update Service also not working.
6. Flashtool: Not working.
7. I know that S1Boot driver is installed, because ive flashed a lot of phones over and over again, only this MT15i failed.
8. The phone is definitely UNROOTED and still on LOCKED. And i plan to let it stay that way until its been updated to stock ics .587.
How can i access flashmode / fastboot without pressing those keys?
No, adb not working.
And now, the phone seems stuck at that SE logo. Waiting for half an hour now, no reboot, just that logo.
Ive heard about the need to use OctopusBox, JTAG and the like, but i want to refrain from using them. (Paid service, not sure if it would work at all)
System: XP SP3 32bit, Win7 32bit, Win7 64bit, Win8 64bit (with disabled signed driver enforcement)
Hi fellas.
This happened when i was unlocking bootloader of my Xperia Go. I installed SDK toolkit, adb drivers & 'android_winusb.inf' (as per the official bootloader guide) and started doing the process ahead. Initially the same problem (as happened with others also) started, the LED turned purple for some seconds then turned orange & went into charging mode (this happened in my laptop at home running windows 8.1, 64bit) then i did the same process with same drivers in my office comp (running windows XP, 32bit) then a prompt came up for installing my phone but installation failed. It asked me to go back and select custom folder, so i browsed to "comp>/C/>program files>android>android SDK>extras>google>usb_driver and clicked next, then it showed two paths with different names but reaching the same target folder viz "usb_driver" and i selected the 2nd one, after which it showed "installation complete". I thought i had resolved the problem but when i connected my phone holding volume Up key, the LED does turn purple (and stays like that all the way) but nothing comes up on computer further..... Can anybody tell what must have gone wrong and how this problem can be sorted out.
This is a kind request to all Modding Gurus PLEASE help me out,, I dont want to get stucked on the Stock ROM forever..:crying::crying:
