Stuck during the boot process
5 Aug 2015
If an Archer 2 or Allegro 2 is stuck during the boot process (while the firmware and operating system are still loading after a reset or initial power on), please let us know if you are aware of any other issues or specific events which preceded this occurrence. If so, please email the information to firstname.lastname@example.org.
One possible cause is removing the battery while the unit is still running (maybe while writes to the internal flash storage memory are still occurring). Removing the battery while the unit is running (does not include at red battery screen) could lead to internal storage memory corruption. Rather than initially removing the battery (even if the unit is frozen), it is better (safer) to instead perform a Hard Reset (by holding the Power button for a full count of 20 seconds) or full Power Off (not just Suspend) first.
When a unit is stuck during boot, some possible solutions are as follows (in order).
- Perform a Hard Reset by holding the Power button for a full count of 20 seconds (even as the screen flashes off and on twice, and even through the blue screen with sliders).
- Perform an extended power removal by pulling the battery and wall charger for a few minutes.
- For possible data recovery if needed (no guarantees), perform a Clean Registry by saving and copying this A2Update.txt file to the root directory of a MicroSD card, insert into unit, and then soft Reset (hold Power button for 5 seconds). Once recovered, perform a Clean Boot as explained below.
- Perform a Clean Boot by holding the Power button for 15-20 seconds until the blue screen appears, move the “Set Factory Defaults” slider, and then tap Exit. This will remove all installed programs and data on the internal flash storage memory hard drive.
- Reload the operating system using the extracted files from the “Direct Install ZIP” as instructed and is available in the following web links.
If the unit has/had an OS release prior to 1.6.1, please install the latest OS release which has some improvements which may prevent such an issue in the future. Storing program and/or data files on an inserted MicroSD card instead may also help.
If the unit is still stuck, you could possibly provide information to email@example.com such as any error message number that appears or at which white box it is stuck on the bottom progress bar. This info could possibly help determine what occurred. But in any case, if the above solutions do not help then most likely the unit would need to be submitted for repair (such as for possible replacement of the internal flash storage memory).
