Reflashing back to stock?

Brick is when the phones internals are fried... Only n00bs call this stuff bricking/unbricking, and only in this forum. Every other forum on xda seems to actually understand what it is

The FTF file you can download from the 2nd link provided above:

I agree i should have been more clear.

Brick - When used in reference to consumer electronics, "brick" describes a device that cannot function in any capacity (such as a device with damaged firmware). ...

Anyway, when xrecovery stopped working and SEUS didnt work either, this was the only choice for me.

Hey, I have a problem. Now my phone do not want to charge, every time I am trying to charge it, the only thing that happens - led is blinking with red color every 3-5 seconds. Nothing else. The battery is OK, it is tested.

Same than I connect it with PC.

So I can not connect phone in the flash mode, because it does not led with GREEN but only with RED

Any ideas how to save my X10i?

I have messed up my phone last night for following some instructions on how to root my x10 but it was actually for 1.6 firmware and i did it on my 2.1-update1 firmware. Right after that, my phone just started to vibrate when i turned it on. The screen turns black and it vibrates non stop. After downloading so many ROMS file to flash, the vibration stops but the screen is still black! It also flickers every 2-3 seconds but not very noticeable. Currently downloading a ROM to downgrade it to version 1.6. Will update you all soon. By that time, please post any recommendation. :(

If you are on an X10a Please use ->

http://hotfile.com/dl/43225669/598add6/a_WWE_R1FA014_DEK.zip.html

If you are on an x10i use -> http://hotfile.com/dl/58256398/134c3c7/i_R2BA026.rar.html

The FTF files are inside the RAR's :)
[XPERIA X10 Q&A, Help & Troubleshooting] a-Rcky:
[Q] How to..?

How do you use those files?:confused:

Actually I'm new into this, but, the FTF files I've seen are the ones you use with Flashtool, as a single FTF file. Instead, this one has many SIN files.

I've made my X10i non-functional by installing 1.6 while on 2.1, please help me with this.

Thanks :D
[XPERIA X10 Q&A, Help & Troubleshooting] l32007:
Hey if you're running on a X10i or X10a you can use this which has a bat file you run and follow prompts.

X10a -> http://hotfile.com/dl/100649934/4add607/2.1_2_1_A_0_435_GLOBAL.rar.html

X10i -> http://hotfile.com/dl/92727093/b2b807a/2.1_2.0.2.A.0.24_GENERIC.rar.html

if you have a X10, the sin files are individual parts of the ftf, you put them in the "firmwares" folder and the flashtool should see them, i believe.

Hi,

I got a problem, i did everything in this tutorial and i have recovered my x10a with the 2.1.A.435 firmware (i had the 2.0.A.504) and all went smoothly until i noticed that my x10a has no signal, no wifi and when i try to turn on the wifi i only get a reboot, the same when i search for networks in settings-wireless-access points names...

i cant connect to wifi nor radio from my provider, and when i go to restore factory settings keeps telling me "insert SIMCard and reboot"

i've tried to do it with the sdcard inserted and without it but no luck...

there is a way to repair this or do i have to return to my native firmware???

here are my phone specifications and modds

Stock

X10a Telcel Branded

Android 2.1 2.0.A.504

Flashing

X10a Generic

Android 2.1 2.1.A.435

[XPERIA X10 Q&A, Help & Troubleshooting] Pierre Duc:
As most of you are having the same issues, I might have a solution..(cuz i had the same as you..)

[The ERROR is because the phone goes out of flashmode if there is no input within a few seconds].. so wait wait wait till flashtool really asks for your phone..

1. download and install the latest flashtool

2. download latest stock firmware

3. place the latest firmware in the firmware folder of flashtool

4. open flashtool

5. press flash

6. select the firmware

7. press 'ok'

8. wait till its done preparing files and bla bla. untill a popup asks you to connect your phone in flashmode

9. remove the battery from your phone for 5 seconds (10 to be safe?)

10. hold the back button, and plugin the usb cable

11. flashtool will now start flashing without an interuption

Attempted 2.3.3 with 0.71 baseband, phone just goes in continuous boot_loop. Ive tried almost every available baseband with no results.

Here is what I have attempted so far:

1. Flash tool and forum instructions:

a) Device will take any 1.6 (branded or unbranded) firmware but wont allow to use any features of the interface other then emergency calling!

b) 2.1 firmware with different revisions/baselines have been attempted as well but device just wont boot at all.

c) after flashing with 2.3 firmware device goes in to constant boot_loop.

2. SEUS couldn't locate the new software as my phone has latest software available from the server. (however I'm still on 1.6 )

3. Same with SE Companion, it comes up with the message that software is not available for my phone yet.

Hi all,

I'm new here and have been looking around the threads to my issue, this seems to the closest, i bought my X10i in april 2010 and soon after i rooted it and its been fine ever since the only issue i have is updating the Android OS to the latest i'm stuck at 1.6 and no matter what i do it won't budge, i can't backup or restore as that fails everytime, and when i search for the latest update via the phone, PC companion and SEUS they all say i have the latest update etc, but i'm always still on 1.6, and half the market's applications are inaccessible to me with more becoming unavailable with the apps updates.

Just to point out i've tried the above and there is no success on several occassions, yes Windows does see the phone and can connect and the phone does work normally.

I don't know how i can sort this as there is no other way i know how to flash the phone.

Does anything here look out of the ordinary? I have removed the IMEI as I believe there is some security risk in posting it, but I am not sure, still, I am sure that the problem isn't with my IMEI.

I have a very similar problem with my x10 (so 1b).

although mine got bricked attempting to flash to 2.3 (using flashtool). further attempts to reflash using flashtool always ends up with "flashing aborted".

now it wont boot, just vibrate once, a quick flash of the green led, then the screen just stays black.

SEUS says i am already on the newest update, and attempting to repair with PC Companion says No Software Available For Your Phone Yet.

have you guys found any solution yet for this?

i might need to bring the phone to the tech already :(

Seus will say you have latest version but it will also say "re-install it anyway?" That'll sort u out (back to stock, unrooted)

@laneyofdeath:

it is that case actually that me and a few others are having a hard time reviving our x10: SEUS will only give us a button that says "exit".

after an extensive read (and re-flashing in between), this is what i've seen:

i came to an article that says x10s that are having the same symptoms as mine (flashing aborted with flashtool, SEUS wont install update, PC companion saying no software available), are caused by NAND memory failure.

in which case, i am not entirely sure if it can still be repaired, or we have a very expensive paperweight

What firmware/os version u using?
[XPERIA X10 Q&A, Help & Troubleshooting] laneyofdeath:
EDIT: Also there a lot of unlocked bootloader talk above do u have unlocked bl?
[XPERIA X10 Q&A, Help & Troubleshooting] necrohades:
as far as i know, bl is still locked. i did run s1tool earlier to check it out.

although i'm not sure how to do unlocking since it wont turn on.

oh yes, it was on 2.3. or was being updated to 2.3 when it got bricked.

come to think of it, maybe i should try unlocking bl first?

EDIT:

blimey, i don't think i can unlock BL without the phone turning on. the process needs root access, and no, the phone is not turning on. i might look for someone who can use a JTAG and possibly have it fixed (hopefully).
[XPERIA X10 Q&A, Help & Troubleshooting] laneyofdeath:
NO! If you unlock bl u really will 'brick' your phone. You cannot Brock your phone as I don't think you have unlocked bl (you would have to do it so you would know) sorry at minute I not home I on night out ill try help u if I can tomorrow. Apologies hope u figure it out.
