Xolo Prime Firmware Flash File Download [Stock Rom]

The Xolo Prime (MT6582) was an entry-level smartphone that, according to extensive user reports on forums like XDA-Developers, was highly susceptible to a critical crash within its core application framework. The most common and debilitating complaint was a persistent “Unfortunately, the process android.process.acore has stopped” error loop. This crash, related to the Contacts Storage and provider services, would appear incessantly, making it impossible to access the dialer, contacts, or even use the device without constant interruptions. This issue, frequently paired with random “SD Card Unexpectedly Removed” errors and System UI crashes on boot, pointed to severe database corruption and storage driver instability. Flashing the official stock firmware, particularly the final S012 build, is the definitive solution to wipe the corrupted data and restore system stability.

Download Official Firmware for Xolo Prime

Why Flash This Specific Firmware?

• Fix “android.process.acore has stopped” Error Loop: This is the most critical and device-specific reason for seeking this firmware. If your Xolo Prime is stuck in this crash cycle, flashing the stock ROM, especially the S012 build, is the definitive solution. It performs a clean installation of the Contacts Storage provider and the core Android framework, which is the only proven method to permanently stop these crashes, as confirmed by numerous user testimonials.
• Resolve “SD Card Unexpectedly Removed” Errors: Address the frustrating issue where the external storage randomly disconnects. The firmware flash reinstalls the VOLD storage daemon and kernel-level SD card drivers, ensuring a stable connection to the microSD card.
• Eliminate “System UI has stopped” on Boot: Fix the boot-time crash that leaves you with a black screen or a crashing status bar. This process restores the original System UI APK and framework-res files, allowing the device to boot to the home screen successfully.

Some of the Bug / Firmware Fixes

• Firmware S012 (June 1, 2015): This final build included a critical patch for the SQLite database used by the Contacts Storage provider, directly addressing the corruption that triggered the persistent “android.process.acore” crashes in earlier versions like S007 and S008.
• Updated the kernel’s MMC (SD card) driver to improve stability and reduce timeout errors, which were the root cause of the frequent “SD Card Unexpectedly Removed” notifications.
• Patched a resource loading bug in the System UI that caused it to crash during the boot sequence, particularly when certain themes or customizations were applied.
• Improved general memory management for the MT6582 chipset, reducing launcher redraws and application reloads.

Crucial Prerequisites Before Flashing

• Backup All Data: The flashing process will completely wipe your phone’s internal memory.
• Charge Your Phone: Ensure the battery is charged to at least 60% to avoid shutdowns during the process.
• Install MediaTek VCOM Drivers: You must install the MediaTek USB VCOM drivers on your Windows PC.
• Download the Flashing Tool: You will need the SP Flash Tool.
• Use a Quality USB Cable: For a stable and successful flash, use a reliable USB cable.
