NOTICE BEFORE PERFORMING:
How to upgrade this iOS 13 quite badly, if you do not have much experience on the restore, you should not use this method. It is best to perform an upgrade on an Apple Mac or wait for the release version to be released
NEED PREPARATION BEFORE SOME “MATERIALS” AS FOLLOWS:
- Download iDeviceRestore: Devjam81 / libimobile2019 (press the Clone or download button> choose to download ZIP)
- Download the iOS 13 beta firmware suitable for the device you are using
You should then transfer the two files (including libimobile2019-master.zip of iDeviceRestore and iOS 13 firmware) into the same folder to make updating easier and more convenient.
SAVE DATA ON IPHONE WITH ITUNES OR 3UTOOLS:
For iTunes, when connecting the device to a computer, the software will automatically send a request for data synchronization (or press the backup button on the device management interface). For 3uTools, open the Device tab> press the Backup / Restore button (directly below the avatar)> select Backup device to PC
- Turn off Find iPhone or Exit iCloud account (if possible)
- Remove the lock password
- Use charging cable according to the machine (best)
- Turn off the iTunes software if it is open (exit runs in the background)
MANIPULATE IOS 13 UPDATE FOR IPHONE ON WINDOWS:
1 COMPUTER : Unzip libimobile2019-master.zip file in the previous download folder
2: Open the Command Prompt (CMD) on the computer> drag and drop the file to enter “idevicerestore” in “libimobile2019-master” into CMD
Enter [space] -d [space] > continue to drag the iOS 13 firmware file (* .ipsw format) into CMD and then press Enter to execute the command line
3: The process of extracting the ipsw file will start and the completion time depends on your computer (from about 10 to 20 minutes)
4: After completing the process of extracting the ipsw file, the device will automatically switch back to the recovery state and start the update process to iOS 13 (similar to when done on iTunes).
