How do I downgrade from 2.2 to 2.1 again - XPERIA X10 Q&A, Help & Troubleshooting

Hi today I flashed the new 2.2 rom with cyanogen v2 and I didnt really like it so I wanted to flash my 2.1 back nandroid style. I did it but it wasn't successful and there was no baseband, therefore no calling or sms. How do I fix this error?

Download the graphical flash tool, download a 2.1 firmware, flash.
http://forum.xda-developers.com/showthread.php?p=10738467

so if i wanted my phone to be exactly how it was before in 2.1, I would still have to flash this baseband?

to make this a little more clear. I made a nandroid of my 2.1 rom before i downloaded 2.2. I want 2.1 back and flashed it but there is no more baseband anymore (.54)

yea if ur baseband is messed up and you want 2.1 again. ur gonna have to relash the firmware that you want.

I can flash just the firmware and keep everything else right? So that way I can get my baseband back. Do you know which one I should flash?

download original 2.1 from xda and try flashing it using flashtool which you can find in this forum. or connect your phone to your pc or mac and try repairing it through SEUS.
SEUS, is only updating the phone which it always said i already have the latest sofwarre (((((

enjoy..........
The reason you didn't had network signal may be that not all roms work with all basebands, so it could have been rom related. Have you also waited till the rom rebooted a few times?

[Q] PC Companion stil asking me to update even thou i have 2.1 on my x10

guyz,
i recently updated my x10 to 2.1, however whenever i connect my x10 to my laptop, PC Companion asks me to update my firmware. why is it doing that? i dont know of any other firmware update. i am based in south africa.
do you guys also know about the PC Companion update for multi touch on x10? apparently already rolled out in china: http://www.xperiax10.net/2011/01/18/official-dual-touch-xperia-x10-update-hits-japan-on-19-jan/
please give us more details of your firmware of your device
(go to settings--->about phone)
If you flashed a custom rom or used xRecovery to load a custom theme, an I'd tag may be overwritten. I'm not able to recall exactly now which, it's not a big deal. I left Seus in the same state for over a month.. when you need to flash / upgrade it's kind of a handy feature even.

Yes i rooted the phone with z4root (1 click) but that was after the update.

What do you recommend i do before i update? back up right? i installed titanium back up, do i back up everything on titanium backup? will the firmware upgrade be a problem if i rooted the phone?
When I updated to .435 it didn't ask to update anymore. After, I was full of 2.1 so I put. 2.2

If you wanna use a lower bb then your best option if you wanna have GB is to go back to an old custom GB rom that works on the older baseband.
hi, you can do it, but be carefull, do it on your own risk!!!!!!!!
what you need is
flashtool http://forum.xda-developers.com/showthread.php?t=920746&highlight=flashtool
baseband http://forum.xda-developers.com/showthread.php?t=960527&highlight=baseband
i hope you know how to use flashtool, so when you have your favorite baseband its an ftf file, open it with 7.zip and delete the kernel.sin, so you will flash only the baseband.
now you are on your favorite baseband with GB kernel, but maybe you cant send sms, then you need an sms patch from here http://forum.xda-developers.com/showthread.php?t=1177744
i tested only bb67 with GB kernel and sms patch on custom rom, and it works for me

It won't be stable unless you switch to a custom rom that supports the chosen baseband.

although this thread is different, the attachment works for you too.
flash it with Xrecovery after installing the rom you want. works for custom roms (genric roms i dont know, maybe).Make sure you only use Xrecovery below 1.0 (dun use 1.0, use 0.3 or 0.2 or 0.1)
it will change the baseband to 46 or 54 nt sure, but it does downgrade. but make sure YOUR ROM IS BASEBAND-DOWNGRADABLE or else your rom will be corrupted. you can also install a new rom AND FLASH IT RIGHT AFTER YOU FLASH THE ROM THROUGH xREC.

Not really, you would need to use the usb port to flash the baseband and the old 2.1 kernel to get it to work.
i need to flash baseband? but when after i restored the backup of my cousin my baseband automatically change. im afraid when i restore it end with Stock in SE Logo.

restore your backup....
you did make a backup before you flashed someothing new?
Always backup in case you f***up..
or use pccompanion t repair back to stock
Which Rom did u flash and which would u like to return to pal? Maybe suggest repairing through seus/pc companion and starting again (or flash global generic with flashtool these will all do same thing) you will need to root again though.

Donut by alzbac do u mean? They best thing pal would be seus it up. Although as Greg said do u have a backup (titanium or something like this)? If not u will have to grab all ur apps back from market. (unless u made a NAND backup)

I want to do that too... I can't root and the Flash tool is the only capable to change the Android version.
I try downgranding to 2.3 and than root, but didin't happen... I used the Rume.bat, the superoneclick, android root... NONE worked.
But flashtool, worked just fine.
HELPPP??
