1. ADB and Fastboot Drivers:
ADB is basic tool for any Android related operation and fastboot is one of its applications. ADB installs all the necessary ADB drivers for Android powered devices and activate the developer mode on device. Various tools require ADB and other components to be installed on the PC for proper functioning. Fastboot is used to issue various commands like for flashing a recovery or a kernel. It is also used in commands related to bootloader unlocking.

Sometimes, you might get the error, waiting for device or similar errors while issuing commands or using any tool. This is mainly due to faulty connection. If you have properly connected your phone with your pC, via a healthy cable and phone is being charged but not being recognized, then the problem is USB drivers. When a phone is connected, PC searched for drivers online and also on PC. You can install USB drivers beforehand and when you’ll connect PC with phone, it will install all the USB drivers automatically. Download the USB Drivers installer from the link given below.
3.Battery must be charged over 50%:
This is one pf the most important precautions and requirements. You must be aware of the fact that most OTA updates can be installed only if battery is charged more than 50%. This is for the safety of device. The device must not turn off during the whole process. Since these are custom methods, phone may enter a bootloop or may plunge into some other problem. Low battery can be a critical issue in these cases. Therefore, you must charge your phone above 50%.
4.Check your Phone Model:
Many times I have seen people bricking their devices because of their negligence. Note that there are several model numbers, with prominent changes for almost every device out there. Therefore, you must confirm that the given guide is for your device’s model number. As an additional precaution, you must also check that the guide is for your phone’s Android version. This is not necessary in all cases. You can check model number and Android version by navigating to Settings > About Phone.
5.Do not turn off Computer during Updating Process:
If either your phone or PC goes down in the mid of process, you might end up bricking up your precious device. Therefore, make sure that your PC will not turn off or restart during the process. If you are using Windows, make sure that there are no pending updates to be installed in, for example ten minutes. PC will restart automatically, disturbing everything. Therefore, make sure that your PC will remain turned on during the whole process.
Also note that devices are not bricked in every case. It is very rare indeed. however, we must always choose the safe path.
6.Backup all your important Data:
Most custom methods will wipe all dat stored on the device. Some methods might not do so but a custom method can make your phone end up in a bootloop and then a factory reset will be essential. Therefore, always make a backup of your device before anything custom. Here is a guide for non-rooted phones, which guides your through all steps to back up a non-rooted device.
You must backup all media files stored in internal storage. As a safe precaution, you might remove SD Card while doing it, however it has never caused anyone any kind of issue. All deleted applications can be installed from Play Store My Apps tab.
If your device is rooted then you have better options for making a backup of your device. You can backup each and every settings along with all applications and all system files along with it. It is pretty useful for restoring your phone to previous state without much hustle. Here is the recommended guide for rooted users.
6.Use correct commands for your smartphone:
You must pay close attention to all the commands described here. You must follow them closely in order to avoid anything unplanned and unpleasant, for that matter. Therefore, always confirm before executing a command.
7.Backup EFS Data(Will be Done after rooting):
This is the first thing that should be done after getting hands on any Samsung device. The EFS partitions contains very critical data like IMEI data and other similar things. If it is disturbed or deleted, the phone may not receive anymore signals and it will be just like a tablet. Therefore, backup EFS data before doing any kind of development on it.
