Install LineageOS 17.1 ROM on UMIDIGI A7 Pro [Android 10 GSI]

For those who want to flash their UMIDIGI A7 Pro device with a custom Android 10 GSI ROM, here’s the good news.  XDA member Andy Yang has released an unofficial LineageOS 17.1 based on Android 10 for the Samsung Galaxy Tab S6 Lite (WiFi/LTE). Those who wanted more customization options than the original ROM firmware on their device can now look forward to dumping the latest version of Android 10 GSI via the LineageOS 17.1 custom ROM software on their device.

Using the GSI (Generic System Image) it is possible for developers or various OEMs to download a generic AOSP system image without changing the startup image or the factory image. According to Google’s certification guidelines, OEMs must test the compliance of their devices with the Treble project by successfully downloading the generic system or GSI image and ensuring that the hardware’s essential features and capabilities are working properly. So, if you have a UMIDIGI A7 Pro, you can install the latest update for your device, which comes with LineageOS 17.1, which is based on Android 10 GSI.

Updates are often aimed at improving the stability of the system and the performance of the device and enabling new functions. Before flashing the user ROM on your device, make sure that the startup charger on your device is unlocked and that you have made TWRP Recovery on the UMIDIGI A7 Pro flash. If you have not already done so, you can follow our TWRP recovery guide for the UMIDIGI A7 Pro.

Brief introduction to LineageOSCustom ROM

LineageOS is the successor to the customer-specific ROM firmware CyanogenMod. It is officially available for nearly 200 devices, while informal meetings are held for a huge list of devices. LineageOS is based on the AOSP source code, similar to Remix Resurrection, SlimROM, Omni, AOKP, Paranoid and others. Although LineageOS is equipped with all the features of Stock Android, it also offers a huge list of configuration features. It comes with several pre-installed applications, including AudioFx, FlipFlap and Trebuchet.

Manual flashing of the UMIDIGI A7 Pro with Android 10 GSI based LineageOS 17.1 CustomROM

Pay attention: Your device must already be marked and secured with the TWRP before you proceed as described below.

Step one: Transfer the downloaded file to the internal memory / SD card of your UMIDIGI A7 Pro smartphone.

Step two: All you have to do now is charge for the repair. An additional backup of the ROMs can be made via the TWRP interface. Nevertheless, I advise you to support the ROM. Because if the process fails, you can make the ROM blink.

Step three: Click Install, then go to the file and rotate your finger over the file to confirm the firmware (at the bottom of the screen). The blinking process of the user’s LineageOS ROM has started and will take a few seconds.

Congratulations, you have successfully flashed the LineageOS 17.1 Android 10 GSI-based custom ROM on your UMIDIGI A7 Pro device. If you have a problem with blinking, feel free to report it in the Comments section below.
