Installing a custom recovery on android is very different from one device to another device. You can’t apply the same method for all android devicess.
 
  1. From Android 5.0 and lower versions of android devices can be installed a custom recovery in two ways.
    • Installing custom recovery without a pc – Using software like Flashify
    • Installing custom recovery from pc

How I can find ways of installing a custom recovery on my device if it’s not available?
  1. Firstly it’s better to search on YouTube.
  2. If you have a Samsung t285yd – galaxy j max tab, you need to search like this TWRP recovery for Samsung t285yd.
  3. Because mobile manufacturers are making lots of devices with the same name. So, the only different thing is basically this device number (t285yd
  4. You can install a custom recovery on your device if it available on youtube
  5. But most of the time we can’t find a tutorial for our device
  6. Then you can search on Google and find a working recovery.
  7. Most of the time XDA gives the best answer for these types of problems
  8. But in this case, you may have a problem of finding the way of installing a custom recovery on your device. 
  9. In such a case you can find a device with the same config that has the same manufacturer (if the manufacture is Samsung you need to find the same manufacture developed device). 
  10. And same android version (if your device is android 5.1 you need to find that kind of another device)
  11. In this way, we can get a 95% success rate. But we need an unofficial TWRP recovery file, (if it’s not available on the official TWRP page) and also a good tutorial that has the same specification to your device.
    • As an example, one of my followers installed TWRP recovery on his Moto g5 (s) plus device following my Moto G5 Plus custom recovery installing tutorial.
 
 
 
What are the things that we must consider when we’re trying to install a custom recovery on our devices?
  • The first thing is to take a full backup of your device. Because it has a 99% success rate to be formatted your full device in the process of installing a recovery. So take a full backup of your phone memory (photos, videos, documents, files), apps, and data. Data can be signed to Google.
  • Be ready for boot loops. During the process of installing a custom recovery,, you might have to face boot loop or soft brick errors. So, it’s better to find a way of installing the official ROM for your device before flashing a custom ROM.
  • Enable developer mode and OEM unlocking. Basically, this is a hidden setting of all android devices. So you need to open the setting and find the build number (search on settings or it’s on about device or software info options.) Tap several times on it until it says Developer mode enabled. Then back to that option and enable USB debugging and OEM unlocking. But OEM unlocking option is only available in some devices like Samsung.
  • Unlocking bootloader. If your device is a newest android device, you need to unlock your bootloader before flashing a custom recovery. But most of android manufacures are closed their bootloader unlocking code providing services when it comes to 2021(Huawei stopped this service)
