In St. Petersburg, Russia, Pavel relied on his Digma Plane 7565N 4G tablet for navigation and streaming. After a partial OTA update corrupted its system partition, his device fell into a boot loop and Wi-Fi refused to connect. This detective-style investigation traces community clues from 4PDA, XDA, and local tech blogs to deliver a foolproof recovery using the official MT6737M 20180316 Android 7.0 firmware.
Case File: Symptoms & Early Clues
- Boot Loop: Tablet displayed “Digma” logo for 10 seconds, then restarted
- Wi-Fi Drop: After boot, Wi-Fi module failed to initialize
- Error Logs: 4PDA thread “Plane 7565N Wi-Fi dead after OTA” referenced corrupted
wifi_socpartition - XDA Tip: Use SP Flash Tool v5.1832 for MT6737M scatter files to avoid “BROM ERROR: S_FT_ENABLE_DRAM_FAIL”
⚠️ Critical Warning
Flashing the nvram.img or wifi_soc.img partitions with incorrect files can permanently disable IMEI or Wi-Fi functionality. Always back up these partitions first.
