I hope someone can help me with this..

I've checked and double check every instruction in this topic, everything went like it should but everytime I change my SIM from one operator to another it keeps asking for an Network Unlock Code.

Flashtools reports it's already unlock, S1 tools shows the version with a small "r" but I must be missing something here.

[XPERIA X10 Q&A, Help & Troubleshooting] Toledo_JAB:
You have a carrier locked SIM. Unlocking the bootloader will NOT unlock the phone to work on different carriers. If your phone was locked by at&t (just for example) like mine was, even with unlocking bootloader you are still locked to at&t. There is a thread on free unlock codes for X10 in general. Otherwise google for pay websites.

Bottom line is you need to unlock SIM

Flashtool not working on Win7 64bit Notebook

I have flashtool v9.10.1 on my Windows 7 Professional 64bit Notebook.

When I access flashtool after installing it, it appears to work OK, but when I select file->exit, the application just hangs and I have to use Windows 7 task manager to "End task".

I have Java(both 32bit and/or 64bit) installed and I've removed and installed other versions of flashtool all with the same result.

I have had flashtool running on my Windows 7 32bit PC with no problems for over a year now, but never been able to get it to work on my 64bit Win7 Pro Notebook.

I have SEUS installed on my 64bit Win7 Professional Notebook and that works fine and I can updated/re-install my firmware on both an XPERIA X10 and XPERIA LT26 without problems.

It just seems to be a problem with my installation of flashtool on my 64bit Win7 Notebook.

So I guess my question is, what am I doing wrong???

If this is a know problem, please just point me to the solution.

Thanks for any advise in advance.

I'm using v0.9.9.0 on my Win7 Ultimate 64bit inspiron laptop with no probs. Is your system slow? Low ram, slow CPU, etc.?
[XPERIA X10 Q&A, Help & Troubleshooting] Dr Goodvibes:
Alienware M11xR1 Win7 Pro 64bit 1.6GHz dual-core SU7300 4GB RAM (~1.5GB used). Even has a discrete GPU (GeForce GT335), not that that should matter.

I thought it was Java and uninstalled Java, then installed 64bit, then uninstalled and used just 32bit then both... but not joy.

I uninstalled Flashtool and re-installed several times

I'm so sure it's something stupid that I've done, as I just can't believe this could happen. :eek:

In the past I just ignored it and used my desktop PC thinking, one of these months I'll figure it out and it'll all come right.... but 12 months later and several flashtool upgrades/re-install and still no joy.

It's almost beyond weird, I install the flashtool application, click on the icon or program application and it starts up flashtool fine.

I then select file from the menu and exit and that's it, the application is 'hung'. Then it's task manager to end the processes.

Oh, one other thing, I have my Notebook running in Test mode as I have some nvidia drivers which are not signed.

But flashtool would be the only application out of tens of others that would be impacted if this was the case.

having issues trying to upgrade to 2.3 GB

I updated my x10 from 1.6 to 2.1 about a year ago. u guys just got 2.1 running pretty smooth and then were toying with the idea of trying to make 2.3 work on the x10. I just got back on the forums yesterday and found out u made it happen. so i'm trying to upgrade again and from what i'm seeing so far we have to put a stock rom on the phone that's not rooted and then pc companion should update to 2.3. well, i do the flashtool steps and now pcc keeps telling me that i'm either up to date or at one point i managed to get an old enough rom on here to get pcc to update and it put it right back to the one i had. so, what am i doing wrong?

upgrade 2 JB

hello all,

yes i am a noob......but i did look first for some answers before i decided to post this....okay here's the case

* i am the proud owner of a X10 Mini Pro also known as U20

* i upgraded long time ago to android 2.1 (original firmware) by means of pc companion

and now of course i like to get a more recent android on my U20.....SE wont help so therefore I resorted to XDA...here's what i managed to do so far:

1. i installed the nice Flashtool version 0.9.10.0

2. i managed to root my device

3. and i managed to unlock my bootloader

4. but now i am in the dark...

i did find some threads on custom ROMS but they are not very specific (for an illiterate like me) on how to deploy them ....

i think Android 4.1.2 JB-CM10 should work on my U20...http://xdaforums.com/showthread.php?t=1779745.....

but i am overwhelmed by his install instructions.

can anyone guide me on the last steps to take to get this custom ROM rocking!!!!

[XPERIA X10 Q&A, Help & Troubleshooting] Beanerman:
Yes it should work for your phone.

I didn't see that u installed a Recovery after rooting and unlocking. You should have a Recovery. U will need to make a backup of your current rom before making any changes to ur phone.

ClockworkMod, nAa, or whichever u choose.

Most deved kernels have a Recovery built in.

The directions r simple for that rom.

U have to download the rom and kernel.

Place the kernel in the flashtool folder on your pc or anywhere u can find it easily. U will have to fastboot flash it to ur x10.

Place the zipped rom u download on ur sd-card, usually in your recovery folder or anywhere it can be easily found.

Now follow the rest of the instructs.

If u need more help, let me know or pm me.

I used flashtool to flash 2.1 rom and after flash completed, phone boots to SE logo (writing) and then is stuck.

I have tried updating using both SEUS and PCCompanion. Both say that they have updated the phone successfully but phone still does not start.

After flashing with PCC boot process was same problem as before except I briefly saw an image of a camera and a blue arrow pointing down to a phone.

After flashing with SEUS, the phone does not start at all. When I press the power button I see red led flash 3 times repeatedly.

I thought maybe battery has died, so I have connected to mains charger.

Now the phone seems flashes red led once (repeatedly) for about 2 minutes, then led changed to solid green for about 2 minutes,then powers-up to SE logo/writing and camera/blue arrow image briefly, before repeating the process again.

I am not sure if the phone is charging or not? (or maybe battery is not even depleted?)

Help to move from Custom ROM (CMOD9) to original SE ROM (2.1 or 2.3)

Hello,

Apologies at the outset in case I'm repeating a question, which has already been answered. Do note that I'm a noob :p so would appreciate your patience.

Using the various great tutorials on the forum, I was able to root my X10i and installed CMOD9, which works well. However, now I wish to go back to the original SE ROM and I was searching for two things:

a) What is the process to do that? Do I need to change both Kernel and ROM? Is there a step to step guide for the same? I have xRecovery in bootup option. How to use it to change the Kernel as well as ROM?

b) Original SE ROM 2.1 - In my searches I came across Generic ROMs listing (http://xdaforums.com/showthread.php?t=1749426) but I was not sure if this is what I'm looking for and it conains both Kernel and ROM. Would request if some expert can comment. Also, I need to know how to find out the version of Android there and the Language?

Thanks a lot for going through my post and any help will be greatly appreciated. In case I should have posted in some other thread, I'm sorry and would be happy to know where to put it.

Generally android version and language is given in name of file and in link provided by you, android version is given on top 2.3.3 kits etc, and language is given with file name.

3. If it's a stock ROM file then why no use official update and if not then read instructions carefully given with file it must be there that what older version you.need to flash and I guess not sure if it's a ftf file then you can flash it with flashtool irrespective of on which version you are currently.

My case: Yesterday I tried to install GingerDX, I had previously installed the Stornmix 1 year ago and I wanted a better mod. So from the menu that appears by holding the Back button, I chose the Ginger zip folder and I received a message that the update was successful so I can now reboot.

Since then, every time I reboot it stops to the Sony logo, no recovery menu or anything else. So I read this post and did the flashing of the firmware that you propose.

I have done it so far, successfully, I viewed the text in your quote in my Flashtool too. Now I am waiting for the X8 to reboot,10 minutes already gone and it still shows only the Sony logo.

So what can I do?

Thank you in advance guys, you do a great job, I know you are not supposed to answer to all these requests that members post, however if you could give me an advice I would really appreciate it! .

Sometimes that happen. Just try to reboot normally if that doesn´t work try to flash again

EDIT: did you flash the correct fw? for your phone?
