I flashed my mu240 from 4.00 to 4.01.
INSTRUCTIONS:
1. Download the archive with firmware 4.01 (
MU240_V4.01.rar ), extract the contents for example in a folder called
MU240_V4.01 2. then go to
... \ MU240_V4.01 \ MU240_YZ667C_B246_QVGA_TRI_320X240BAR_MRuEn_V01.02B14-P_RELEASE \ PC_SYNC_TOOL there is an archive
EGO_SyncTool_Setup.rar , also extract the contents for example in a folder called
EGO_SyncTool_Setup 3. go to
... \ EGO_SyncTool_Setup \ EGO_SyncTool_Setup \ x64 if you have a 64 bit system, if you have a 32 bit system, then go to
... \ EGO_SyncTool_Setup \ EGO_SyncTool_Setup \ x86 run
DPInst.exe all questions click
YES (Continue anyway) 4. Restart the computer, while booting the computer, press the button
F8 , we choose there
Disable driver digital signature verification 5. In the folder
... \ MU240_V4.01 \ MU240_YZ667C_B246_QVGA_TRI_320X240BAR_MRuEn_V01.02B14-P_RELEASE run the program for the firmware
UpgradeDownload.exe , in the program we press the button
Start download 6. Remove the battery from the phone, hold down the SIM1 call button, connect the cable, insert the battery, wait a couple of seconds and the firmware program will go through the firmware, release the SIM1 call button
7. The whole process will take 159 seconds. Once in the column
Progress will appear
green lettering , press the button in the program
stop loading , remove the cable from the phone.
EVERYTHING Bottom line: the phone works without complaints. All three sim cards catch the network perfectly. The problems that I had on firmware 4.00 disappeared (I could not dial 2 phone numbers, I press a call, and he writes me "I can not dial this number", although I could send a message to these numbers).
