@Abducted
Thank you for your explanations. From the Acer download site, the latest version for the Duo (FR version) is 1.000.18 (OS_Acer_E350.1.000.18.EMEA.FR_A40I_A.zip). There is no SD zip format for the ROM nor the FlashTool format on Acer FR site.
On the mentioned "vache" link
http://vache-android.../Liquid Gallant
it has old version 1.000.08, the SD zip is OK, but the FlashTool version is corrupted. One can see though the content of it:
zip:\bad_Acer_AV041_E350_1.000.08_EMEA_FR.zip\Acer_AV041_E350_1.000.08_EMEA_FR\boot.img
zip:\bad_Acer_AV041_E350_1.000.08_EMEA_FR.zip\Acer_AV041_E350_1.000.08_EMEA_FR\logo.bin
zip:\bad_Acer_AV041_E350_1.000.08_EMEA_FR.zip\Acer_AV041_E350_1.000.08_EMEA_FR\MT6575_Android_scatter_emmc.txt
zip:\bad_Acer_AV041_E350_1.000.08_EMEA_FR.zip\Acer_AV041_E350_1.000.08_EMEA_FR\preloader_simcom75_cu_ics.bin
zip:\bad_Acer_AV041_E350_1.000.08_EMEA_FR.zip\Acer_AV041_E350_1.000.08_EMEA_FR\recovery.img
zip:\bad_Acer_AV041_E350_1.000.08_EMEA_FR.zip\Acer_AV041_E350_1.000.08_EMEA_FR\system.img
zip:\bad_Acer_AV041_E350_1.000.08_EMEA_FR.zip\Acer_AV041_E350_1.000.08_EMEA_FR\uboot_simcom75_cu_ics.bin
So I assume the FlashTool version you use is 1.000.18? If yes, where did you find it? (since it is not in Acer FR site). I would like to have this file (guess: I could use \Rom content and zip the 7 files from it?).
From what you said, I understand that the EUU is only a wrapper package, invoking under the cover the FlashTool to flash the phone, hiding any technical details for plain user. It has the advantage of not requiring the phone running (since battery taken off), nor being rooted, nor running under recovery as with SD update zip.
It would be nice if Acer (or someone) releases also the SD update zip format for the latest ROM.
