What is a flash file and why do you need it?
A flash file is a script file that contains the software or operating system of your device. It is stored in the flash memory of your device, which is a type of non-volatile memory that can be erased and rewritten. Flashing your device means replacing the existing flash file with a new one, usually to fix software issues, upgrade features, or change the user interface. Flashing your device can also improve its performance, stability, security, and compatibility.
What is SPD MTK and how does it differ from other chipsets?
SPD MTK is a smartphone chipset that stands for Spreadtrum MediaTek. A chipset is a set of integrated circuits that control the functions of your device, such as CPU, GPU, memory, camera, network, etc. SPD MTK is one of the most popular chipsets for low-end and mid-range Android devices, especially in China and India. It offers low cost, high performance, and good compatibility with various software and hardware components. However, SPD MTK also has some drawbacks, such as poor battery life, overheating, and lack of updates.
There are other types of chipsets for Android devices, such as Qualcomm Snapdragon, Samsung Exynos, Huawei Kirin, etc. Each chipset has its own advantages and disadvantages in terms of performance, power consumption, features, compatibility, etc. Depending on your device model and specifications, you might need a different flash file or tool to flash your device.
What are the common problems with Lenosed L99 Tab and how to fix them?
Lenosed L99 Tab is a budget-friendly Android tablet that runs on SPD MTK chipset. It has a 7-inch display, 1 GB RAM, 8 GB ROM, dual SIM support, dual camera, Wi-Fi, Bluetooth, GPS, etc. However, like any other electronic device, it can also encounter some problems that affect its functionality. Some of the common problems with Lenosed L99 Tab are:
Hang logo: This happens when your device gets stuck on the boot screen or the brand logo and does not proceed to the home screen. This can be caused by corrupted system files, faulty hardware components, malware infection, or insufficient memory.
LCD problems: This happens when your device's display shows abnormal colors, lines, dots, or black screen. This can be caused by damaged LCD panel, loose connection, water damage, or software glitches.
Dead boot: This happens when your device does not power on or respond to any button press. This can be caused by a faulty battery, charger, power button, motherboard, or software corruption.
Software errors: This happens when your device shows error messages, crashes, freezes, or reboots randomly. This can be caused by incompatible apps, virus infection, outdated firmware, or corrupted system files.
To fix these problems, you can try flashing your device with a new firmware that is compatible with your device model and chipset. Flashing your device can also help you unlock your device, remove FRP lock, bypass password or pattern lock, root your device, etc. However, flashing your device can also be risky and void your warranty if not done properly. Therefore, you should follow the instructions carefully and backup your data before flashing your device.
