[HTC Incredible S] bslim:
ambuj, perhaps the file is not being replaced somehow (I have similar experience previously). I would advice you unzip the rom to a folder, replace the default.xml file with that given by djroobs. Then zip the rom back (make sure the extension is zip and NOT rar).

To learn a bit xml code, you may download notepad++ (http://notepad-plus-plus.org/). Open both default.xml files (from Multilanguage rom and non-multilanguage rom) with notepad++ . Comparing the code from both files, I am sure you know how to convert to multilanguage later on.

For example: if you see the following code after replacing djroobs file, this means you do not replace properly:

<module name="locale">

<function>

<set name="single">

<item name="total_list">zh_CN;zh_HK;zh_TW;en_CN;</item>

<item type="boolean" name="zh_CN">yes</item>

<item type="boolean" name="zh_HK">yes</item>

<item type="boolean" name="zh_TW">yes</item>

<item type="boolean" name="en_CN">yes</item>

</set>

</function>

</module>

Zh_CN: Chinese simplified, zh_HK: Chinese Traditional HK, zh_TW: Chinese Traditional Taiwan, en_CN: English

The xml file given by djroobs should contain:

<module name="locale">

<function>

<set name="single">

<item name="total_list">ar_EG;ar_BH;ar_DZ;ar_JO;ar_KW;ar_LB;ar_LY;ar_MA;ar_OM;ar_QA;ar_TN;bg_BG;bg_BY;bg_CS;bg_CZ;bg_EE;bg_HR;bg_HU;bg_LT;bg_LV;bg_PL;bg_RO;bg_SI;bg_SK;bg_UA;cs_BG;cs_BY;cs_CS;cs_CZ;cs_EE;cs_HR;cs_HU;cs_LT;cs_LV;cs_PL;cs_RO;cs_SI;cs_SK;cs_UA;da_DK;da_FI;da_NO;da_SE;de_AO;de_AT;de_CH;de_DE;de_ES;de_FR;de_GB;de_IE;de_IT;de_KE;de_LU;de_MZ;de_NA;de_NG;de_NL;de_PT;de_ZA;el_GR;en_AE;en_AM;en_AO;en_AT;en_AU;en_AZ;en_BG;en_BH;en_BY;en_CH;en_CS;en_CZ;en_DE;en_DK;en_DZ;en_EE;en_EG;en_ES;en_FI;en_FR;en_GB;en_GE;en_GR;en_HR;en_HU;en_ID;en_IE;en_IQ;en_IT;en_JO;en_KE;en_KW;en_KZ;en_LB;en_LT;en_LU;en_LV;en_LY;en_MA;en_MZ;en_NA;en_NG;en_NL;en_NO;en_OM;en_PL;en_PT;en_QA;en_RO;en_RU;en_SA;en_SE;en_SG;en_SI;en_SK;en_TN;en_UA;en_US;en_ZA;es_ES;es_FR;es_GB;es_IE;es_IT;es_PT;es_US;fi_DK;fi_FI;fi_NO;fi_SE;fr_AE;fr_AO;fr_AT;fr_BH;fr_CH;fr_DE;fr_DZ;fr_EG;fr_ES;fr_FR;fr_GB;fr_IE;fr_IQ;fr_IT;fr_JO;fr_KE;fr_KW;fr_LB;fr_LU;fr_LY;fr_MA;fr_MZ;fr_NA;fr_NG;fr_NL;fr_OM;fr_PT;fr_QA;fr_SA;fr_TN;fr_US;fr_ZA;hi_HI;hr_BG;hr_BY;hr_CS;hr_CZ;hr_EE;hr_HR;hr_HU;hr_LT;hr_LV;hr_PL;hr_RO;hr_SI;hr_SK;hr_UA;hu_BG;hu_BY;hu_CS;hu_CZ;hu_EE;hu_HR;hu_HU;hu_LT;hu_LV;hu_PL;hu_RO;hu_SI;hu_SK;hu_UA;it_AT;it_CH;it_DE;it_FR;it_GB;it_IE;it_IT;iw_IW;ja_JP;ko_KR;nb_DK;nb_FI;nb_NO;nb_SE;nl_FR;nl_LU;nl_NL;nl_BE;pl_BG;pl_BY;pl_CS;pl_CZ;pl_EE;pl_GB;pl_HR;pl_HU;pl_IE;pl_LT;pl_LV;pl_PL;pl_RO;pl_SI;pl_SK;pl_UA;pt_AO;pt_ES;pt_FR;pt_KE;pt_MZ;pt_NA;pt_NG;pt_PT;pt_ZA;ro_BG;ro_BY;ro_CS;ro_CZ;ro_EE;ro_HR;ro_HU;ro_LT;ro_LV;ro_PL;ro_RO;ro_SI;ro_SK;ro_UA;ru_AM;ru_AZ;ru_BG;ru_BY;ru_CS;ru_CZ;ru_EE;ru_GE;ru_HR;ru_HU;ru_KZ;ru_LT;ru_LV;ru_PL;ru_RO;ru_RU;ru_SI;ru_SK;ru_UA;sk_BG;sk_BY;sk_CS;sk_CZ;sk_EE;sk_HR;sk_HU;sk_LT;sk_LV;sk_PL;sk_RO;sk_SI;sk_SK;sk_UA;sl_BG;sl_BY;sl_CS;sl_CZ;sl_EE;sl_HR;sl_HU;sl_LT;sl_LV;sl_PL;sl_RO;sl_SI;sl_SK;sl_UA;sr_BG;sr_BY;sr_CS;sr_CZ;sr_EE;sr_HR;sr_HU;sr_LT;sr_LV;sr_PL;sr_RO;sr_SI;sr_SK;sr_UA;sv_DK;sv_FI;sv_NO;sv_SE;th_TH;tr_AT;tr_CH;tr_DE;tr_TR;vi_VN;zh_CN;zh_HK;zh_TW;</item>

You also should compare the default.xml located at customize\MNS\

This file set the default language during first boot:

<module name="defaultLocale">

<function>

<set name="single">

<item name="auto_detect">false</item>

<item name="defeault">zh_CN</item>

</set>

</function>

</module>

This means default language is Chinese.

<module name="defaultLocale">

<function>

<set name="single">

<item name="auto_detect">false</item>

<item name="defeault">en_GB</item>

</set>

</function>

</module>

This means default language is English (GB).
