Flashing, Upgrading, Downgrading, Unbricking the Xperia X10 (FlashTool 0.2.9, 0.2.8)

UPDATE: 2011 July: v2.3 Gingerbread has been released. The firmware file is in the Flash Tool website, as always. This video shows how to use the Graphical Flash Tool (v0.2.8, v0.2.9.1 beta) to flash the Sony Ericsson Xperia X10. This video demonstrates downgrading to a carrier-branded AT&T firmware (v1.6) then upgrading to a generic (unmodified, all features intact) v2.1 firmware. It then purposely bricks/messes up a flash to show the phone broken/noot booting and finally, flashing it again to restore it to working condition. The tool can flash v1.6 firmwares, v2.1 firmwares, different basebands, dual touch drivers and other modifications. It can also be used to “un-brick” an X10 if anything goes wrong. eg boot loop, stuck at the Sony Ericsson logo, small screen, etc. caused by tweaking/modifying/rooting/etc. You CANNOT brick/ruin/break the X10. It will ALWAYS go into flash mode (from off, hold the back button, connect the USB cable). You can flash ANY firmware onto ANY X10 — even AT&T (so stop asking if it’ll work on your X10). Your phone does not have to unlocked, rooted or anything else. Flash mode overrides everything and is before any software is loaded. (Once v2.3 Gingerbread is released in Q3, it’ll flash those firmwares too. And no, I don’t know when it’ll be released.) Flashing does NOT re-lock a SIM/network unlocked phone. Unlocking is ONCE and PERMANENT (and is independent of any firmware on the phone). Some reasons to use the Graphical Flash Tool: – can

    I could not turn on my phone after first step “Press Flash “

    @victormoore Then do it again. Or use another version of the FlashTool. Or use another firmware. Or use Update Service.

    If your phone is brick or cant turn ON, or stuck on the SE LOGO, always use Update Service. That’s what i’m telling people to do whenever they brick their phone or stuck. Unfortunately, i am too lazy to create a video about that BUT, thank god i found your video. Nice work.

    @darsheffect I’ve never used Gordon’s so I don’t know.

  8. darsheffect - September 27th, 2011 at 2:56 am

    @BluechipJ So I installed and opened it successfully . Now i also had ny phone detected with gordon ‘s gate. It says flashing loader and after a few minutes says aborting loader. What to do?

  9. BluechipJ - September 27th, 2011 at 3:32 am

    @darsheffect Use Update Service to repair.

    NTDVM is the DOS emulator. Something’s wrong with your Windows install or you’ve got some program blocking the FlashTool.

    @genuislau91 Mirror added to the description. Mediafire at the bottom.

  12. genuislau91 - September 27th, 2011 at 4:47 am

    Where do you downoad this Update Service software? SE website says its unavailable~

  13. BluechipJ - September 27th, 2011 at 5:18 am

    @stephineebabiee I don’t think someone’s posted v2.1 AT&T firmwares. Download v1.6, available in the description and update from there.

  14. stephineebabiee - September 27th, 2011 at 6:14 am

    where did you get the att firmware? the one i found said att and when i turned it on it said rodgers

  15. BluechipJ - September 27th, 2011 at 6:42 am

    @Lucian5800 That’s what “unbricking” is.
    Flash it again. In the video, I unplug it and purposely mess it up… then I… flash it again.

  16. Lucian5800 - September 27th, 2011 at 6:47 am

    I had Android 2.1, I installed custom ROM official GingerBread 2.3.3 with ftf bundle and that changed the baseband. I wasnt happy with what I got so I restored the stock ROM i backed up before.Now when I go to restore with xrecovery it says device is busy and anything else I try on xrecovery says cant mount sd card so I cant even use the custom rom anymore. when i go to power on my phone it gets stuck in the text “Sony Ericsson” before logo and then restarts.Help me please can flashing fix this?

  17. BluechipJ - September 27th, 2011 at 6:48 am

    @colguile1 Unless you can update over-the-air and root, you won’t be able to update. You need to be able to get xRecovery onto the phone. Then you can flash an entire custom ROM through the ZIP file (by downloading it).

  18. colguile1 - September 27th, 2011 at 7:45 am

    my usb port is completely broken, is there a way to upgrade using files on the sd card? i’ve been using a battery charger to charge batteries b4 any1 asks :D my x10 is stuck on 2.1 stock.

  19. BluechipJ - September 27th, 2011 at 7:59 am

    @MyDiseasedPenis Use Update Service to repair it.

  20. MyDiseasedPenis - September 27th, 2011 at 8:00 am

    @BluechipJ I flashed it like 10 times, still the frozen screen. as for using the pc companion, it keeps on asking me to drag the status bar down and tap connect usb which i can’t do cause the screen doesnt work.

  21. BluechipJ - September 27th, 2011 at 8:17 am

    @josema0890 So flash it again. As shown in the video, if a flash screws up, just flash it again.

  22. BluechipJ - September 27th, 2011 at 8:44 am

    @MyDiseasedPenis Then flash it again. Or use PC Companion to repair it again.

  23. josema0890 - September 27th, 2011 at 8:47 am

    @josema0890 I give you a link with my problem in xda: showthread.php?p=16126854#post16126854
