FAQs
Q1. Can I update this tablet to a newer version of Android like Nougat or Oreo?
No. Android 6.0 Marshmallow was the final major OS version officially released by Acer for the Iconia One 10 (B3-A20B). This firmware restores that version; no further official upgrades are available.
Q2. Is this the same as the Iconia Tab 10 (A3-A40)?
No, they are different models. The A3-A40 is a higher-spec model with a Full HD display and quad speakers. This firmware is strictly for the B3-A20B model and they are not interchangeable.
Q3. The performance is very slow, especially with modern apps. Can a flash make it faster?
A clean flash will restore the tablet to its original performance by removing junk files and software bloat. However, the MediaTek MT8163 and 1GB of RAM are not powerful enough for most modern applications. The tablet will still struggle with demanding games or multitasking after the flash.
Device-Specific Troubleshooting
- Tablet is stuck on the “Acer” or “Iconia” logo: This is the most common bootloop issue for this model. The definitive fix is to perform a full firmware flash using the SP Flash Tool guide. This will erase all data but will install a fresh, working copy of the operating system.
- Battery Drains Quickly Even When Idle: A clean flash will resolve software bugs causing abnormal battery drain. To get the most from the large battery, reduce the screen brightness, which is the main power consumer on a 10.1-inch display. Also check `Settings > Battery` for any third-party apps using excessive power.
- “Unfortunately, Touch WakeApp has stopped” Error: This is a common error on this tablet related to Acer’s specific software features. A full firmware flash will reinstall the Acer apps and should resolve this conflict. If it persists, try clearing the cache of “Touch WakeApp” in `Settings > Apps`.
- “Invalid IMEI” or “NVRAM WARNING” after Flashing: This critical error occurs if you use the “Format All + Download” option in SP Flash Tool. It erases the device’s unique identifiers. To prevent this, always use the “Download Only” mode. Restoring a lost IMEI is a very complex process.
