Just flash 2.1 filmware with flashtool. Turn on debugging. Root it and run qsd8250_semc.cmd file. Make sure you close flashtool. After running, your phone turns off, wait and it will go on, press key again and wait again. your semc tool says succesfull ect and your done.

If you want to go back to you gingerbread rom. Install with flashtool Z xrecovery and wipe everything. also format system, data, cache. Do a full restore of your rom. ( offcourse make backup of your rom before doing this)

After reboot take of battery and back and flash latest kernel and baseband.

[XPERIA X10 Android Development] iridaki:
I did it this way and it was a HUGE success!! :D :)

To sum up, this is exactly what I did:

1. Flashed Kernel Downgrade in FlashTool

2. Disconnected the phone, left FlashTool running.

3. Ran the unlock cmd.

4. Pushed Power Button, when I felt the vibration, I immediately connected to USB.

5. At this point phone was of course stuck at SE bootlogo (2.1 kernel on 2.3 firmware). I waited for FlashTool to "see" the phone. Took a while because my PC (Win7) was looking for drivers. Once it was done, FlashTool saw the phone.

6. Closed FlashTool and pressed enter on the cmd window.

7. The phone restarted one time during the procedure (my heart skipped a beat, I admit) but in less than 1 minute, the cmd reported Success.

8. Closed the cmd window and pulled the battery from the phone (was of course still stucked at SE boot logo).

9. Ran FlashTool again, selected Flash, chose Kernel Upgrade and when it prompted, I put my X10 in flash mode and the procedure completed soon afterwards.

10. I turned on the phone, started spamming Back button and entered xrec, wiped dalvik and cache (because I am on goro's kernel) just in case and then rebooted for the last time!!

Phone was up and running in about 5 minutes (due to the cache wiping, boot was sloooooow). Now everything is good! It was much easier than it sounds!

Thanks to the_laser and everyone else involved now and in the future! :)

THX Iris for pointing this out again. Critical steps are 5 --> 6. If 6 cant adb connect. Pull out batt and start from 1. thats what I did and it worked 2nd time. :)
[XPERIA X10 Android Development] iridaki:
You're most welcome!

The important thing is to WAIT and NOT PANIC in step 5.

It can take a while for the phone to be detected and you actually have time since the phone is stuck at boot logo, and it will stay that way for a looooong time! ;)

as i recall rageagainstcage is in z4root and z4root couldn't unlock kernel before 2.3.3 so you should probably change root method on this way of cracking... use psneuter from 0.3.0.0 on place rageagainstcage and all should be good...
[XPERIA X10 Android Development] Mobzter:
just wanted to say thanx to u guys and the_laser for making it happen & doom for his kernel. ive finally managed to put it all together :D

this is the way i managed to resolve mine.. incase others are still having problems with the ways described here already

1) flash 2.1 firmware via Flashtool

2) once your phones switched on and usb debugging on, within Flashtool hit root, let it restart.

3) now if your phone wasnt unlocked from beginning (like mine) - once phones detected by Flashtool, close it and then use qsd8250_semc.cmd, else the latter. once successful like code shown in first post @ http://xdaforums.com/showthread.php?t=1253277, press any key as stated. (the extra necessary files can be found here too)

4) close command prompt, open FlashTool, once phones loaded again and detected in Flashtool hit Ask Root Perms then XRecovery

5) restart phone and hold back key till you access Recovery and install rom - if you happen to have sdcard problem because device or resource busy then visit - http://xdaforums.com/showthread.php?t=859571&highlight=xrecovery+device+OR+resource+busy

6) from here i just went onto installing my rom, restarted and was about to give up when the sony ericsson logo appeared, but thought id flash doomkernel (http://xdaforums.com/showthread.php?t=1253853) to see what would happen after seeing lukas'z message and to my amazement it actually worked out :D

p.s - u may be able to restore rom and kernel in one go without restarting during step6.. and also thanx again to Robert & Lukas for all their help today!! ;) :D

after all that effort think i need to have a good munch and a shower haha! :p
[XPERIA X10 Android Development] norigkgp1:
Hi Iris ( or whoever ), i´m going to do your exact steps, but I´want to know ( and i´m sure that a lot of others ): if something goes wrong, can we come back to stock 2.3.3 just using PC Companion if we are stuck at any time ?

Is the only step that is stopping me right now.

Tnx. :)
[XPERIA X10 Android Development] aR_ChRiS:
Not sure if you can revert using PC Companion, but I'm sure that you can revert back to normal using flashtool.
[XPERIA X10 Android Development] Chillaxed:
so does this mean we can now just load up cyanogenmod firmwares as they come out through the app and reboot and auto flash new roms? i miss doing that on my HTC magic back in the day......

when are we getting official cyanogenmod suport?
[XPERIA X10 Android Development] iridaki:
If you are already in 2.3.3, flashing only the 2.3.3 kernel will get you un-stuck!

There's no messing with system or data in the way that it's described in this thread! ;)

THANKS :)

I've just followed the steps in the OP and my x10 has the BL unlocked,and doom's Custom Kernel 4b.

my x10 did not die and i had no problems at all using this method

Thanks you all ;)
[XPERIA X10 Android Development] scattaman:
Same issue here... I dont know what prompt to look for to know when flash tool "recognizes" the phone because after flashing the downgrade, nothing happens visually in flashtool and my phone just sits at the se logo for one hour!
[XPERIA X10 Android Development] kalel29:
flashtool opens a window asking your xperia model,after selecting your model,you must close flashtool and let the bootloader unlocker,do its job. and make sure that you are using the correct batch file to unlock the bl ,check the op

[XPERIA X10 Android Development] Taosaur:
Success! I uninstalled/reinstalled Flashtool, restored my ROM backup, and was able to downgrade and try again. This time everything went without a hitch and I got DoomKernel installed.

FWIW, I tried Plugins > Unlock bootloader in FlashTool first and got "Warn: Canceled."
[XPERIA X10 Android Development] 9Lukas5:
Excuse me, it's not against you personally, but is nobody here able to read?! I have written into the first line of the thread, that you should use flashtool for unlocking the bootloader now, because normally if you have unlocked the bl you are going to flash a new rom. So, why are there many people who don't care that line??

I'm a bit confused.

[XPERIA X10 Android Development] hovensy:
As Taosaur said... flashtool gives Warn: cancelled result that' s why we tried old method.. I tried and failed and needed a jtag to restore my phone.. Im not sure what happened as it shows success but it died afterwards
[XPERIA X10 Android Development] Taosaur:
Many people are reporting no joy with flashtool. I forget if it was the flashtool thread or a different one, but on one thread half the last page was people saying "The flashtool, it does nussing!" So, I tried your old method first, but when I did get my phone straightened out and attempted the flashtool plugin, it did squat and I had to go back to your method.

Thanks for putting the guide together. It's a real scavenger hunt tracking down all the files now, though, thanks to my government breaking the internet with the whole Megaupload thing :mad: I don't even know where I would have found Azuzu's files if I didn't still have them in a dark corner of my hard drive from rooting.
[XPERIA X10 Android Development] hakkai999:
Tried following the steps up to opening the batch file. It opens the cmd window but it just closes after I press a key. Whats up with that?

Tried using flashtool FYI Warn: Cancelled everytime.

Edit 2: Plugin menu disappeared. IDK wtf happened.

Now it only shows to small squares when I click the plugin menu :confused:

Edit 3: Now phone wont stay on flash mode anymore. *sigh*

Edit 4: I dont know what to do anymore /wrist plus no one's online that can help

Edit 5: I flashed azuzu's upgrade. Now it boots and Im not doing anything until someone can help with me with this :(

Last Edit: Im now 100% frustrated. If anyone is online and is reading this please add me up in yahoo messenger and if you have a kind heart enough to help me :(
[XPERIA X10 Android Development] 9Lukas5:
I haven't yahoo messenger, but if I understood all your edits correct, you have now a running stock system, correct?

Then please have a look with s1tools on your bootloader and post the output marked as code here. Then I can tell you if you have unlocked the bootloader yet or not.

[XPERIA X10 Android Development] hakkai999:
Actually I reflashed DonutHD.

Can you please point me to the thread where it has the 2.3.3 flash for flashtools? I only saw the 2.1.

EDIT: YES! Finally. Im now using M&M MUI and their custom kernel.
[XPERIA X10 Android Development] varsas:
My sim was unlocked by a shop and the s1tool states it can not determine the certificate so I guess I should try setool2 but it looks like a smartcard i.e. special equipment is required?

EDIT: Assuming that I am stuck and can not do anything about unlocking the bootloader, are there locked bootloader CM7 or CM9 roms? I had a quick look at the main ones seem to need the unlock...

have done everything dont know what button to press to get into the recovery :/ doomlord kernel
[XPERIA X10 Android Development] Taosaur:
Basically any of them; DK comes with 3-4 recoveries. Menu or back should get you xRecovery, volume down should get you Doomlord's touch recovery (which is mostly less usable than the non-touch ones, IMO) and CWM is in there somewhere. You'll see the Doomkernel splash screen, then the device will buzz and the LED will go blue, and that's when you start hitting your button. I never tried to get a boot menu on Doomkernel, but on kCernel alternating between back and volume down got me Doom's boot menu with all the recoveries listed.

HELP!! =(

anyone can help me with my problem?

I have already unlock my bootloader ( god knows how i do it )

recently i have a problem ( NO SIM-CARD FOUND ) Just by flashing a ROM. (impossible right?)

i have been flashing/changing from ROM to ROM. ( no problem ) until now.

So i have restore my bootloader. so that i can unlock it again. now my bootloader is lock.

but the unlocking part. i face this problem, (attachment)

i have this problem before when i first unlock my bootloader ( LONG TIME AGO )

and i forget how i solve this problem.

so anyone know how? - latest flashtool does not work too. that why i doing the old way.
[XPERIA X10 Android Development] icbless:
when the plugin is visible.

go to flash mode

warning, cancelled

then it shows disconnect.
[XPERIA X10 Android Development] whitefang3456:
???

It's not impossible, because some Unlocked bootloader ROMs still haven't fix sim pin unlock screen (means you only can use the ROM to call/messaging/data networking with

SimCard with no unlock pin number

)

Which Unlock Bootloader kernel And ROM you used after Unlocking Bootloader? And what ROM you using before relocking it back? Relocking is simple, but back to its functioning steps to get your X10 works, differ due to which ROM/kernel you used.

i was on oodie ROM, i flash to CosmicUI ( to try out ), got everything FC when start up, sim-card unavailable.

so i flash back to oodie ROM, but sim-card still unavailable.

i flash back to stock rom, sim-card still unavailable

i was on [X10_MiUi Prime_OKernel THmod V3 kernel]. then to try CosmicUI i flash to [CosmicUI-kernel-kCernel_v01]

now i on STOCK ROM, with LOCK BL. no sim-card found.

now i want to unlock my boot loader and see if sim card works, but i getting this ( attachment from prevision comment ) is a common problem, happen to me last time, but i somehow figure it out. but now i am hopelessly stuck =p

is r8A033 and loader version different that why sim-card not found?
[XPERIA X10 Android Development] whitefang3456:
Actually, to be honest. Simcard unlock nothing related to locked or unlock bootloader. Separated matters. Its unlocking purpose is to allow phone to install custom kernels and install custom ROMS and overwrite stock kernel (when everytime you see Sony Ericsson logo after you power on your phone) because stock kernel has limitations, so if want to achieve certain higher software version, have to used customised kernel for remove those limitations.

In loader version, r means unlocked, R means locked. Seems losing software version info if not mistaken: world something numbers... And, Did you see any SIMlock certificate after result in S1tool? Like SEMC or SETOOL2? If no simlock found, probably thats the cause of error of unlocking and relocking back, and also simcard not found cos lost simlock data...

Another: what can you see after powered on your x10? Got recovery? Or Blackscreen? And, did you backed up some locked roms in xrecovery? If there are, might can figure something out.
[XPERIA X10 Android Development] icbless:
just a quick question about no sim-found problem.

no..when i power on my phone..EVERYTHING IS FINE!!! just that they say, no sim-card, please insert one and restart your phone. thats all.

i try different sim-card

i put different sim in my phone and it works.

i put my sim in my phone = does not work

i put my sin in diff phone = work

so is it my phone problem? like boot loader..

is my phone rejecting my ONLY sim-card?! what is going on. =p
[XPERIA X10 Android Development] whitefang3456:
Maybe these?

I came with few possible causes:

1)Probably the ROM/phone don't recognise your Simcard's GSM Carrier anymore. Most common if sim works in other phones but not in your phone. Certain Customised ROM or unlocking procedures might overwrite your Phone's data that recognises your SimCard's GSM network. Once it's been modified/overwritten/deleted, the phone may/will not recognise your SIMCard and cannot connect to network Anymore. Rumors said can be fixed if asking your country phone provider to fix that by reinstalling software/scripts/updates..I'm not sure because my X10 worked Well.

2)Is your SimCard has

Pin-password protected

while other SIM cards you said have no pin password? Probably ROM can't detect pin-locked simcard.. ;)

3)Simcard slot Cannot read your sim card data.

Try take it off and use eraser to rub the chip section on simcard and reinsert it

. See whether it works or not. :) This possibility might be tiny chance since other phone recognise your SimCard

4)Worst case you might need to use other sim card i'm afraid. :p

Probably reason (1) most explainable.

Hope helps.

hey everyone,

I'm running DonutHD 2.27...it says in the first page that the easiest way to unlock bootloader is to go from stock 2.3.3...does this mean that I'd have to "repair" my phone, and then root and unlock the BL?
[XPERIA X10 Android Development] icbless:
no. there is no pin password.

yes, i am using another phone right now. and my sim card works perfectly. so i don't know the problem. i have already call my mobile carrier to send me another sim-card. it will arrive tomorrow. i hope this solve the problem.

as for (1). i use MIUI rom, Stock rom. both sim-card not available. so i think is the phone rejecting my sim-card.

Flashtool~

When you flash any CUSTOM KERNEL using the new version of FLASHTOOL, It will tell you the status of your BOOTLOADER either it is UNROOTABLE (LOCKED) or ROOTABLE (UNLOCKED), but make sure that you've succeed with the BOOTLOADER-UNLOCKING process. :angel:

Use the S1TOOL to check if you've succeed with UNLOCKING THE BOOTLOADER. :D:cyclops:
[XPERIA X10 Android Development] whitefang3456:
S1TOOL link here as Sinatra mate said. But you also can use S1tool to identify your Bootloader status too actually. If your LOader version result started with lower case "r" means unlocked, while uppercase "R" means locked bootloader. :) If interested For zipped PDF tutorial guide for trusted Unlocking bootloader ,it's under my signature last link ;) Extra: I strongly suggest you to check your SIMLOCK Certificate [whether SEMC/SEtool2] before unlocking.

Kernels + Custom ROMs

Congratulations on your UNLOCKED BOOTLOADER! Most of the custom ROMs comes with its own kernels. But as an option, you can flash modded kernels (light, medium or high overclocked / underclocked) [kCernel as an example; modded by @Championswimmer] depends on what ROM you want. Some suggestions are mentioned in the development threads and general (ROM's discussion threads) itself. Pay attention on such things because flashing modded kernels that's not provided by the devs of the ROMs means that you also will have to flash the wifi modules of the modded kernels. ;):fingers-crossed:
[XPERIA X10 Android Development] whitefang3456:
No Problemo

No problemo and Congratz for unlocking bootloader (ULBL) :D Depends because there are few kernels can work with many custom ROMs for unlocked bootloader.

ROM Developers normally will link recommended custom kernel links to intergrate/work best along with your Custom ROM download link

. Please also Note that not all kernels are compatible to one Custom ROM.

So yes, you may need to flash new Kernel.ftf file via flashtool :) and flash new wifi modules or bugfix.zips via recovery mode like Xrecovery/ClockWorkMod :) These extra steps are needed since you no longer in locked bootloader. Hope helps again :D

[XPERIA X10 Android Development] whitefang3456:

It's okay. My English not good as well :p

FS in DoomKernel stands for FailSafe which means minimal/no harm It's

Non-Overclock Version Kernel by DooMLoRD

up to 998MHz (our original CPU's performance)Works like stock kernel, but just tweaked little bit instead overclocked

While another on you mentioned is

Heavy-overclocked version

up to 1228MHz..Some X10 may not handle such frequencies and may encountered random lag/reboot/unknown issue.

Another is optimal/moderate overclocked version up to 1113MHz. This frequency many X10 from different countries can support and works ideally in daily use :D Most custom roms can support this version too. :D

Hope this helps again :D
