Q: How do I know which Android version my Acer B3-A30 has?
A: If you are stuck at FRP, you can’t see Settings. Check your box or look up the serial number on Acer’s support site. B3-A30s with build number ending in WW_GEN1 are usually Android 5.1.
Q: The YouTube method isn’t working. Why? A: Google disabled the “Uninstall updates” button on newer Play Services. Try Method 1 or 3 instead.
Q: Will an Acer B3-A30 FRP bypass wipe my data? A: Yes. Almost every bypass method ends with a factory reset. FRP is designed to protect data, so bypassing it inherently removes the old encryption.
Q: Can I update my tablet after bypassing FRP? A: Yes. But be careful: Updating to Android 7.0+ will re-activate stronger FRP security. If you bypass once, turn off “OEM unlocking” in Developer Options.
This classic exploit works on many older Acer B3-A30 units that haven’t been updated past Android 5.1.1.
Step-by-step:
Note: This resets the tablet again but removes the previous account lock.
This is the most common technique for devices of this era (Android 5.x - 7.x).
If the software glitches don’t work, you must flash a patched boot image or a specific firmware that disables FRP.
Risks: This can brick your device. Only do this if you are comfortable with MediaTek (MTK) flashing.
Prerequisites:
The Process:
Hardware methods are the most effective for the Acer B3-A30 because the USB OTG port is active during setup.
You will need: An OTG cable and a USB mouse.
