77BD Help FAQ: Browser and Device
Check four things first
Chrome, Firefox, and Edge
On these three browsers, pages usually work properly; in older versions the login screen may freeze, so keep updated.
Android 8+ is fairly stable
The 77BD App generally runs well on Android 8 or above; on very old phones the menu may take longer to open
3 GB RAM helps
At least 3 GB RAM makes it easier to open multiple tabs; many users in Dhaka run it on work phones
Grant APK permission once
When installing the 77BD APK, unknown sources permission may be required; once set you don't have to do it again
Browser Settings
If cookies are disabled, pages load slowly; clearing cache and trying again resolves most problems
Device Compatibility
Even on small screens, it works; reading and tapping the menu is easier on displays larger than 6 inches
77BD Help FAQ: Connection and Loading
If the network is slow, take two
If the page loads slowly
First switch from Wi-Fi to mobile data, or vice versa; often the page loads within 10 seconds after the signal changes
If it disconnects repeatedly
Close background apps, then refresh the page; during long sessions a network reset may be needed
If speed drops at night
The network can be busy after 10 PM; clear the cache and open a new tab to check
Use bKash, Nagad, and Rocket
Many users in Dhaka have separate questions about bKash, Nagad, and Rocket; help is faster when account details are matched

77BD Help FAQ: Errors and Crashes
All three codes are commonly seen
Error 101
This usually occurs if the login data is incorrect; re-enter the password, then refresh the browser
Error 204
If the network is unstable, this code may appear; wait a minute and try again; often it clears up
Error 309
If the version is old, 309 may appear; update the 77BD App or 77BD APK and reopen
What to do after a crash
Close the app completely and reopen; if still not, restart the device, especially on older Android phones
If the screen freezes
If too many background apps are running, it may freeze; closing 2 to 3 apps reduces the load
