its DA problem you need to find DA that suits to that model

Hi, with the update of the infinity 2.21 mtk module it is not necessary to use files from abroad or from the internet, as you open the module you leave it as it is, tick Ssla, Hwreport, identify the phone, you also have to know or try according to mtk processor and phone security, preloader mode or broom mode connection, remember to force broom mode by pressing the volume keys.

Both the acer and asus, try the internal file Da.swec.bin. You have to try and test. Greetings.

Hello again, you have tried the preloader mode connection and change the internal file day, by default MTK_AllInOne_DA.bin appears, try Da.swec.bin, please read the threads when they answer or try to help you.Comment that there is not only the 2044 base there are many more and within those bases there are internal infinity files, try and test, it all depends if the model is old or new, mtk processor if it is new or old, security of the old phone or new, greetings.
