W810i GPRS problem

[djape48]

Exatcly which files should I use in my case for flashing?

For example:

W810_R4EA031_MAIN_GENERIC_HN_RED49 and W810_R4ED001_FS_S_E_EUROPE_RED49 and customization for S E Europe. I use that combination and it works very good. If you have problems with xs++ you can try with SE Tool 2 Lite
