It was designed to provide an affordable 4G LTE experience, featuring a 5.0-inch HD display and powered by a UNISOC (Spreadtrum) SC9832 processor. This guide provides the official stock ROM (.pac file), which is the definitive tool for reviving a bricked device, fixing software glitches like bootloops, or performing a complete factory restore.

Device-Specific Troubleshooting for Digma Citi Motion 4G
- PC Not Detecting the Phone? Check Drivers: The most common problem is a driver issue. The SPD Upgrade Tool will not see your phone if the drivers aren’t installed correctly. You must install the Spreadtrum VCOM drivers, which often requires disabling ‘Driver Signature Enforcement’ in Windows first.
- Using the Correct Boot Key Sequence: The phone must be fully powered off. Click the “Start” button in the flash tool first. Then, press and hold the Volume Down button on your phone and connect the USB cable. Do not release the button until you see the ‘Downloading’ progress bar appear.
- Stuck on Google Account (FRP Lock): If you are stuck on the Google account setup screen after a factory reset, flashing this stock ROM will completely wipe the device and remove the FRP lock, allowing you to set it up from scratch.
PMT changed for the ROMError: This error can occur if you have tried to flash an incompatible custom recovery or ROM. It means the partition layout is different from what the stock ROM expects. To fix this, you may need to use the SPD Research Tool (a more advanced version of the Upgrade Tool) and re-partition the device according to the stock layout.
FAQs
Q1. My phone is extremely slow and storage is always full. Will this fix it?
Yes. For a device with only 1GB of RAM and 8GB of storage, a clean flash of the stock ROM is the best way to resolve severe performance issues. It removes all accumulated junk files and restores the phone to its original, lightweight state. After flashing, be very selective about the apps you install to preserve performance.
Q2. Can I upgrade this phone to a newer Android version?
No. The Digma Citi Motion 4G’s official support ended with Android 6.0 Marshmallow. Due to its basic hardware and regional focus, a custom ROM community for it is virtually non-existent, so no unofficial upgrades are available.
Q3. Will this unlock my phone from its network carrier?
No. Flashing the stock firmware restores the phone’s original software, but it does not remove the SIM/network lock put in place by a carrier.
Q4. What is a .pac file?
A .pac file is a packed firmware file used for Spreadtrum/UNISOC chipsets. It contains all the necessary partitions—system, boot, recovery, etc.—in a single, integrated file for flashing.
