Redmi 7A: When itβs needed and how much youβll have to pay
The Xiaomi Redmi 7A, launched in 2019, is still a popular budget device. However, as time goes on, its factory firmware becomes obsolete, and users face slowdowns, errors, or the desire to install a custom version of Android. The cost of firmware depends on many factors: the type of firmware (official, custom, recovery after a failure), region and method of execution (independently or in a service center).
In this article, we will discuss:
- πΉ Current prices for firmware in services and private masters (data 2026).
- πΉ The difference between official and custom firmware β which is best for Redmi 7A.
- πΉ Risks and pitfalls that are silent in salons (from blocking the Mi Account to the brick").
- πΉ A step-by-step guide for those who want to sew the phone themselves.
Important: Redmi 7A is a low-end product, and its hardware constraints (1-2 GB of RAM, Qualcomm Snapdragon 439) impose restrictions on firmware choices. Some custom builds may not work smoothly or even start at all.
Official firmware vs custom: what to choose for Redmi 7A
Before we talk about price, we need to decide on the type of firmware. Xiaomiβs official firmware guarantees stability, but often contains unnecessary software and restrictions. Custom firmware (such as LineageOS, Pixel Experience) offers more freedom, but requires unlocking the bootloader and can be insecure.
Let's compare the key differences:
| Criteria | Official firmware (MIUI) | Castom firmware (AOSP) |
|---|---|---|
| The cost of firmware in the service | 500β1500 β½ | 1000β3000 β½ |
| Requires unlocking of the loader | No. | Yes. |
| Support OTA-update | Yes. | Depends on the build. |
| Risk of "bricking" | Minimum | High for errors |
| Possibility of rollback | Yes. | Partially (requires backup) |
An important nuance for the Redmi 7A: due to the weak Snapdragon 439 processor, many custom firmware based on Android 12+ work with lags. The best option is builds on Android 10β11.
If your goal is simply to upgrade to the latest version of MIUI, the official firmware will be cheaper, and if you want root rights, removal of embedded applications, or an alternative interface, youβll have to consider custom options (and be prepared for the extra cost).
