If your Digma Citi 1590 CS1207MG is stuck in bootloop, has touchscreen malfunctions, IMEI issues, or charging problems, flashing the official stock firmware is the most effective solution. This guide provides all available firmware revisions, detailed SP Flash Tool instructions, and community-tested troubleshooting tips to restore your 10.1″ tablet to optimal performance.
🚨 Critical Pre-Flash Warning
Flashing will permanently erase all data on your Digma Citi 1590, including photos, apps, contacts, and settings. Create a complete backup first. Using the wrong firmware revision can cause permanent touchscreen failure, display issues, or IMEI loss. Never use “Format All” mode unless absolutely necessary—this can damage NVRAM and require professional IMEI restoration.
