Master reboot freezes on Continue

I have the latest 3.4 update files to fix my navram problem of going back to AM radio after startup. Currently running CYAN 3.4 23088 but can’t put system back into factory default mode to load newest files. System freezes when Continue is selected.

SYNC Region: NA

Navigation Variant: Nav

Manufacturer Year: Pre MY20

Install Type: OEM

Old SYNC Version: 3.4.23088

New SYNC Version: 3.4.23188

Do you have a error message, if so what is it?

Update Method: CyanLabs Manual Method

23088 (as 22251) has a bug in which the rwdata partition gets full and the unit exhibits that behavior.
All known methods for recovery are located here → APIM Sync Settings Not Saving, VER_ERR08 Errors, Cannot Perform Master Reset or Upgrades/Updates (Solved)

If none of those work, we do not have anything else to recommend.

A user recently shared his experienced, where after 10-20 minutes of trying the SR → SR → MR combo the MR completed correctly, which enabled him to run the rwdata cleaner and then go to the latest version (which has the bug fixed).
