Hi namma !
Thank you to have given me points :-)
However, to flash the stock rom for your device seems a little different (in the procedure) from other devices. I've uploaded it and you can download it from here:
[Only registered and activated users can see links Click here to register]
BUT it seeems that I must give you two other softwares to run this stock rom ... WAIT please the 2 softwares that I'll give you soon.
OK ... you can download the other 2 files from the links below :
Acer Tool :

Acer driver :

Follow these steps :
1- Download this tool: Acer A1 DL TOOL
and the drivers from Acer's support site , then install them;
2- Extract the zip file into Desktop
3- Move the .bin file in the ACER_A1_Bin subfolder placed into A1_DL_Tool_v3.100 folder
4- Connect your phone (it must be turned ON) to your PC
5- Run the “ACER Download Tool executable (If you're using Vista/7 you must run it in compatibility mode,with administrator privileges)
6- Click the BROWSE button and search for the .bin file you previously put into ACER_A1_Bin folder
7- If you're not using .bin files provided by Acer, you may incurr in the INCORRECT MD5 alert. Just don't care about it and proceed to the following step.
8- Click START, and remember, DO NOT stop the flashing process, DO NOT unplug your device, or you'll damage your device.
