X10i won't boot - I tried everything (YES! Everything!) - XPERIA X10 Q&A, Help & Troubleshooting

Hi guys,
I have problem with my X10i phone. In a row, I:
1. Installed stock rom from SEUS
2. Rooted device via flashtool
3. Unlocked bootloader via flashtool
4. Installed kernel (FeraKernel) via flashtool
5. Installed custom rom from CWM (Achotjan ROM)
6. AND then I've got an Wi-Fi issue, so I installed other kernel -> nAa 14. After that device won't boot AND I cannot:
- Flash it (in flashmode too)
- Boot
- Root/Shell Root (via SuperOneClick)
- Install stock soft via SEUS or PC Companion (repair in Companion won't do)
- Hard Reset by pressing keys (left, right and power)
- Unlock via ... Emma (Emma, right? From Sony) - It calls that I have blocked device
I can do nothing besides start in flashmode, which gives me nothing, cause I have problems flashing other kernel. Flashtool waits for device or gives me an RED COLOR Error: "SIN header verification error".
Can I do anything with this device or simply put it in a trash?

AW: X10i won't boot - I tried everything (YES! Everything!)
can't you get into flashmode? maybe battery is empty... naa kernel is bullshiit forget it... search for thread "diXperia 7" avenger for 2.3.3 baseband+kernel or look in x10 development section for 1.6 .ftf file and try to flash those via flashtool. you dont need to power your device on to flash. it is thr only way (i know) to debrick a phone.

I tried this: http://forum.xda-developers.com/showthread.php?t=2145994 - without flashing mode it won't start
PS. I CAN GET INTO FLASHMODE. But it gives me nothing, cause I have errors or my PC can't recognize phone after flashing by nAa kernel...
EDIT: I tried with generic rom - still error: "SIN verification header error"

No - I can flash NOTHING. My phone is not recognized by SEUS, so I think there's an error related to that header from an error in flashtool

in kernel. it is just: you het your kernel, put ut in firmwares folder, go to flashtool, choose it and plug your device while pressing back button.

Yup, rom + kernel in ftf file. Search it yourself. I've done it with x8 and I found the rom+kernel ftf.

I got exact the same error trying to flash .ftf from flashtool.
19/017/2012 03:17:46 - ERROR - ERR_SEVERITY="MAJOR";ERR_CLASS="SECURITY_CLASS";ERR_DYNAMIC="SIN header verification failed"
For me this was because I did not have an unlocked bootloader.
I spent at least a whole day trying to resolve the problem as months earlier I had an unlocked bootloader and everything worked.
For me I resolved the problem by unlocking the bootloader...'again'.
Have you run S1 Tool and verified that you have an unlocked bootloader at this time?
LOADER VERSION: "R4A024" means a locked bootloader. If it a lower-case "r" then you're fine and you have an unlocked bootloader.
If you get SEMC SIMLOCK CERTIFICATE at the end of the S1 Tool information output then at least there is still something readable in the boot image of your phone.
It is odd though, when I had a locked bootloader on my XPERIA X10i I was still able to install a SEUS firmware upgrade.

I have unlocked bootloader earlier, but maybe I have it locked again. How can I unlock bootloader without device connected (by turning it on)? I can only start it in flash mode, which doesn't allow me to unlock bootloader in flashtool. Also I cannot update firmware using SEUS

AW: X10i won't boot - I tried everything (YES! Everything!)
I just had the same or at least a similar problem (sunday it happened) and solved it by flashing the 1.6 rom and the 2.3.3 only kernel +baseband, first found in dev section, second in dixperia 7 thread and then updated via seus. It didn't work at first try but now i have the working stock rom and cannot root anymore. If you try this please tell us if you can root afterwards.
And try to boot 1.6 first - it is nice and i wanna know if it works for you. You can look in my profile to find the thread i created with details.

And you've tried S1 Tool to see what it returns?
If you can't view the information results or the results indicate your XPERIA X10i is in a state that does not support an unlocked bootloader (due to corruption) then at least you have a documented state at which your phone can or can't operate.
If the XPERIA X10i can't load ANY firmware, then you'll have to start analyzing the low level boot code to find out what is corrupted and how bad it is. S1 Tool is an easy info display to a least be able to say, "OK I can get a return information display from S1 Tool" and I have posted the output so people can better understand the situation.
If you can not install firmware via Sony Ericsson Update Service(SEUS), PC Companion or Flashtool 'flashmode' using a generic GB 2.3.3 ftf.
Then you're limiting your options. You still have flashtool 'fastboot mode' BUT indications are that you HAVE to have an unlocked bootloader for it to work.
Have you tried flashing a 'STOCK' GB 2.3.3 ROM via flashtool flashmode? [Completed]X10 Stock Firmware Collection
Have you placed the xxx.ftf file to be flashed in /flashtool/firmwares/ folder?
Does your XPERIA X10i have drivers installed on the PC so that the USB connection is established and recognized?
If the USB connection is not recognized, have you run the driver install from /flashtool/drivers ?

Ok, so:
1. I tried to flash stocking ROM - I Have an error with SIN header.
2. Yes, I placed file in given directory
3. Yes, I have drivers on my PC (Gordon's Gate too) - PC has been recognizing a phone before. Now I have only "device connected in flash mode" information.
4. SEMC Debrand doesn't work.

The fact that the phone and the PC are communicating is good. Now you just have to wait for some smart person that knows the boot code your phone is missing. I've got nothing.
