The Mobiistar X1 Selfie (MT6737T) is an entry-level Android smartphone based on the MediaTek MT6737T chipset, often used as a budget device with a focus on selfie cameras and basic daily tasks. This model commonly faces software faults like bootloops after failed OTAs, storage exhaustion from heavy media use, or devices stuck on the Mobiistar logo following root or app conflicts.
Installing the matching stock ROM can help restore the original system partitions, resolve these instability issues, and return the phone to a functional factory state without repairing any hardware problems.
This page provides a preserved stock firmware package for the Mobiistar X1 Selfie MT6737T Indian variant, suitable for use with MediaTek scatter flashing tools. The package is mirrored from a Google Drive link and intended for technically capable users familiar with SP Flash Tool.

⚠️ Flashing Risks & Disclaimer
Flashing the Mobiistar X1 Selfie with an incorrect MT6737T scatter file or interrupting SP Flash Tool can cause a hard brick, IMEI loss, or modem calibration failure. Because the device depends on region‑specific preloader, radio firmware, and partition layouts, cross‑flashing from non‑IN variants or other MT6737T phones can lead to no network, unstable WiFi, or corrupted storage that requires advanced recovery methods.

How to Flash the Firmware
- Download and extract the ROM: Get the Mobiistar_X1_Selfie_MT6737T_IN_V1.10_08232018.zip and extract it on the PC to reveal the MT6737T scatter file and partition images.
- Install drivers and launch SP Flash Tool: Install MediaTek VCOM drivers, open SP Flash Tool, and load the scatter file so partitions for the X1 Selfie are listed.
- Set flashing mode: Choose “Download Only” for repair or “Firmware Upgrade” for clean install, skipping NVRAM/preloader format unless needed.
- Connect and flash: With the phone powered off, click “Download” in SP Flash Tool, then connect the Mobiistar X1 Selfie via USB for preloader detection and flashing.
- First boot: After success confirmation, disconnect and power on; the initial Android 8.1 boot may take several minutes for cache optimization and app setup.

Frequently Asked Questions (FAQs)
Is this firmware compatible with non‑IN Mobiistar X1 Selfie variants?
No. This IN (India) MT6737T package is region‑specific; flashing it on global or other regional models can cause network or modem issues due to mismatched radio firmware.
What software faults does this V1.10 ROM help fix on the X1 Selfie?
It can resolve bootloops from OTAs, soft‑bricks after root or app overload, devices stuck on logo, and system instability from corrupted vendor partitions.
Does flashing require bootloader unlock on MT6737T?
Usually not; SP Flash Tool uses preloader mode on the Mobiistar X1 Selfie, allowing stock ROM recovery with the factory bootloader.
Will this upgrade Android beyond 8.1 Oreo?
No. The package restores stock Android 8.1 Oreo for the X1 Selfie IN variant without providing newer major Android versions.
Why is the file on Google Drive rather than an official site?
Original Mobiistar downloads are discontinued; this is a preserved stock ROM mirror for legacy device support.
Can data be retained during flashing?
Selective modes may preserve data, but for reliability on unstable systems, a full clean flash with wipe is recommended after backups.
Does this affect warranty or service options?
As a preserved stock image for an older device, warranty is likely expired; technicians can verify it as factory software.
