Troubleshooting Common Issues

Why install a custom ROM on an iPlay 40?

• Updated Android versions: Alldocube often ships older Android builds with limited update support. Custom ROMs can provide later Android releases or security patches.
• Remove bloatware and vendor restrictions: Stock images may include preinstalled apps and services you can’t uninstall otherwise.
• Performance and battery optimizations: Custom kernels and ROMs can tune CPU governor, I/O schedulers, and wakelock handling.
• Privacy / de-Googled builds: Some ROMs omit Google services for users wanting fewer data-collecting components.
• Feature additions: Enhanced UI options, gesture navigation improvements, advanced theming, and extra developer options.
• Community experimentation and learning: Hobbyists creating ports or fixes for hardware quirks.

3) Unlock the bootloader

Warning: this erases user data.

1. Reboot to bootloader:

adb reboot bootloader

2. Check fastboot recognizes device:

fastboot devices

3. Unlock bootloader (one of these commands, depending on device fastboot implementation):

fastboot oem unlock

or

fastboot flashing unlock

4. Confirm on-device prompts if required. Wait for process to finish, then reboot:

fastboot reboot

If unlocking is blocked by vendor or requires an unlock token, you must follow Alldocube-specific instructions from the vendor or community ROM threads.

Step 4: Flashing the Custom ROM (GSI Method)

Since there are few "device-specific" ROMs, you will likely be flashing a GSI. Troubleshooting Common Issues Why install a custom ROM

1. Prepare the Image:
   • Download your chosen GSI image file (usually ending in .img).
   • Rename the file to system.img.
2. Open SPD Research Tool:
   • Run ResearchDownload.exe (often included in SPD flash tools).
   • Click the Load Packet button (usually the first icon on the left).
   • If you have a .pac file for the custom ROM, load it here.
   • If you are flashing a raw .img file (GSI): You usually need to load the Stock Firmware PAC file first.
3. Modify the Configuration:
   • Once the stock PAC is loaded, click the "Start" button (usually a play arrow icon) in the software.
   • Look for the partition named "System" in the list.
   • Uncheck every partition EXCEPT "System" (and sometimes "Boot" or "VBmeta" if the ROM instructions specify to flash those separately). DO NOT FLASH PRELOADER unless you want to hard brick the device.
   • Double-click the "System" line and select your downloaded custom system.img file.
4. Enter Download Mode:
   • Power off the tablet completely.
   • Press and hold Volume Up and Volume Down buttons simultaneously.
   • While holding both, plug the USB cable into the PC.
   • If drivers are installed correctly, the tablet screen might stay black, but Windows will make a "device connected" sound.
5. Flash:
   • The SPD Tool should detect the device and start flashing automatically (or you may need to click "Start" again).
   • Wait for the green circle "Passed" notification.
