Crucial Warning: Flashing via flash_all.bat reformats internal eMMC 5.0 flash storage, permanently erasing all downloaded apps, saved media, user accounts, and local documents. Packages carrying the ferrari identifier belong strictly to the 64-bit Snapdragon 615 Mi 4i platform. NEVER flash packages meant for the standard Mi 4 (cancro), which runs a 32-bit Snapdragon 801 processor, different partition tables, and incompatible baseband binaries. In addition, do not cross-flash with the hexa-core Mi 4c (libra) or Mi 4s (aqua).

Flashing Overview for Xiaomi Mi 4i
- Verify your phone codename is ferrari using fastboot getvar product.
- Extract the .tgz archive twice using 7-Zip until flash_all.bat and the images folder appear.
- Power off the phone and hold Volume Down + Power together until the FASTBOOT screen displays.
- Open Mi Flash Tool, select the extracted firmware root directory, and choose "clean all".
- Click "Flash" and keep the phone connected while partitions stream into eMMC 5.0 storage.
Expand preparation checklist for Xiaomi Mi 4i
- Verify your device codename is 'ferrari' by executing 'fastboot getvar product' from a command line while in Fastboot mode.
- Confirm that your phone model is 2015015 and not the standard Snapdragon 801 Mi 4 (cancro).
- Install official Qualcomm HS-USB QDLoader 9008 drivers and updated Android SDK Platform Tools on a 64-bit Windows PC.
- Ensure the 3,120 mAh battery holds at least 50% charge before beginning the flashing process to prevent shutdown during partition writes.
- Extract the .tgz archive twice using 7-Zip until flash_all.bat and the images directory appear in the root path.
- Connect the phone via a quality microUSB 2.0 data cable directly to a rear motherboard USB port to avoid communication drops.
Compatibility & Bootloader Notes
Early Xiaomi Mi 4i production units on MIUI 6 shipped with open bootloaders. Xiaomi introduced bootloader locking with later MIUI updates. Bootloader unlock can be performed using the official Xiaomi Mi Unlock tool. Devices in unrecoverable bootloops can be restored via Emergency Download (EDL 9008) mode; the Snapdragon 615 platform on ferrari does not require authorized server firehose credentials.

Frequently Asked Questions
The Snapdragon 615 2nd Gen (MSM8939) is fabricated on a 28nm LP process node and uses an octa-core ARM Cortex-A53 CPU layout. It groups cores into two clusters: four performance cores operating at 1.7 GHz and four power-efficient cores clocked at 1.0 GHz, paired with an Adreno 405 GPU running at 550 MHz. Xiaomi collaborated with Qualcomm to introduce revised thermal throttling profiles and dynamic CPU frequency governors in the 2nd Gen revision to balance heat dissipation across the polycarbonate chassis under Android 5.0.2 Lollipop.
The Mi 4i incorporates a 5.00-inch Full HD 1080p IPS LCD display sourced from Sharp and JDI, featuring a pixel density of 441 ppi, 95% NTSC wide color gamut, and One Glass Solution (OGS) full lamination. The display controller includes Qualcomm's Sunlight Display technology, which performs real-time pixel-level dynamic contrast adjustments in hardware based on ambient light sensor readings. Official factory Fastboot packages restore the original display initialization routines and color calibration lookups stored within the persist partition.
The standard Mi 4 (cancro) and Mi 4i (ferrari) belong to completely different hardware generations and CPU architectures. The Mi 4 runs a 32-bit Qualcomm Snapdragon 801 (MSM8974AC Krait 400), whereas the Mi 4i runs a 64-bit Qualcomm Snapdragon 615 (MSM8939 Cortex-A53). Their GPT partition boundary layouts, primary bootloader binaries (sbl1.mbn and emmc_appsboot.mbn), and modem baseband files are entirely incompatible. Attempting to write cancro binaries to ferrari corrupts the boot sequence and drops the device into an unbootable state.
The Mi 4i integrates a Qualcomm Gobi multi-mode LTE modem supporting Dual SIM Dual Standby (DSDS) via two physical Micro-SIM slots. Both SIM trays share access to 4G LTE and 3G WCDMA networks, allowing users to toggle software data connectivity between SIM 1 and SIM 2 without physically swapping cards. Flashing the complete official fastboot firmware writes matching NON-HLOS.bin modem firmware and baseband calibration data, ensuring reliable dual-SIM registration and carrier band discovery.
