Tomaso, there is already a R1L version for LAM_2 at DaVinci???
By the way, I think that only changing the CDA won't work when updating through SEUS, I read in another post that it also checks the phone's IMEI, take a look at this:

Thanks for the info my friend. Have you tried running SEUS to check whether it downloads LAM_2 or whichever firmware you previously had?
I presume there will be lots of upset people if the IMEI-CDA combination is indeed a determinant of which firmware SEUS downloads. Assuming this is true, there is absolutely no point (to my knowledge) in modifying the CDA with Davinci!
I must say this is quite upsetting...

After flashed my phone with R1J firmware, LAM_2 customization and changed the phone's CDA to CDA102337/105 R1A LAM_2 and trying to use SEUS update service I get the following message:
Your device is not permitted to use this service
Your operator does not approve the usage of this service for this device.
We look forward to assist you again soon.
Thank you for using Sony Ericsson Update Service!
Anyone knows the reason of this message, it is because no newer firmware (R1L not yet released for this customization) is available for LAM_2 customization???
Thanks!! |

You can indeed change the CDA without reflashing, but it will cost you a credit.

Is it possible to downgrade from FW R1L to R1A with Da Vinci for the sake of better Video Quality and will the W800 FW be available for changing from K750i to W800 and if you do can you go back to K750i FW?

@Paulino2
There is no poin changing back from R1L to R1J as the video quality is exactly the same (Rev 4.4) If you wanted to get the video quality back you'd need to flash back to R1A (Rev 3.8 ).

Sorry I meant to R1A of course cause the videos now get guite useless as with R1J. But is it possible with Da Vinci?

@Muppet,
I guess SEUS uses a similar nethos as Cruiser's "autodetect" be reading the TAC part of IMEI from OTP, hence detecting what model it is and hence making it impossible to fool SEUS unless you find and undertsand that CALL in the code

This is BAD news... It seems as if changing the CDA is pointless for future SEUS usage afterall. Refer to the K750>W800 thread for interesting technical information. |

Well, I unbranded my K750 and changed the CDA to the correct CDA. SEUS now downloads the correct, unbranded firmware. Seems to work as desired  |

Maybe that's why SEUS downloads the right unbranded firmware, your phone was bought in Europe and flashed with an european variantion....so when SEUS check the IMEI and CDA it noticed nothing strange...
But my phone is from Honk Kong, with APAC_1 customization, IMEI probably belonging to asia zone...so, when SEUS checks my IMEI and CDA (actually changed to LAM_2) it noticed that I'm not telling the truth so it downloads the hong kong firmware.....
That's what I think about all this CDA/IMEI check!
