You might notice that a Spreadtrum backup made using Infinity Chinese Miracle II (CM2) SPD doesn't look like a regular pac file which can be flashed using using Spreadtrum flash tools like Research/Upgrade Download tool, Miracle Box etc because its in pac.sc format.

For this reason, such a backup can only be flashed back using CM2 SPD. This guide explains how to convert that pac.sc (and other files / folders) to a single pac file.

Requirements


Steps to convert Infinity CM2 SPD pac.sc to pac file


Follow the steps below to convert Spreadtrum pac.sc to pac

See the video tutorial below or at https://youtu.be/mjrsqXQU7OY

  1. Launch Chinese Miracle II SPD

  7. CM2 SPD should now start packing the various partitions into a pac file

  8. Once packing is done, CM II SPD should start signing the PAC file

    [Image: How-to-convert-Chinese-Miracle-II-CM2-SP...file-9.jpg]

  9. Once signing is done, you should get a Done message with the path to the newly created .pac file

  10. Check to confirm that your Spreadtrum pac file was successfully created

Important Notice
  • Infinity CM2 ideally requires a hardware dongle to work. Installing and running the module alone won't work
  • If you're using a loader version then you are entirely responsible for heeding to or ignoring any virus warning you get
  • You can flash in both pac and pac.sc format using Infinity dongle. The reason for converting is so you can flash the pac file using other tools like Research / Upgrade download tool, Miracle Box etc

Video Transcript
Quote:In this video tutorial, I'll be explaining how to convert an Infinity Chinese Miracle 2 SPD backup to a pac file which can be flashed using other Spreadtrum Flash Tools like Miracle Box, Research Download tool and the rest. Now, when you make a backup of a Spreadtrum phone using CM2 SPD, you'll notice that it looks something like this. You can't exactly flash this using other tools. You can only flash this format using Infinity CM2 SPD. I'll explain how to convert this to a single pac file.

Now, you need to have created this backup already okay? If you don't know how to create this CM II SPD backup, we have a tutorial at the forum and a video on our YouTube channel. Check it out & follow, create your backup. I also assume you already have your Chinese Miracle II SPD all set up okay? Now, once you have these available,  launch your Infinity box CM2 SPD and wait for it to come up. Alright! Chinese Miracle 2 SPD is up. Now, click on Extra - FW Converter - Convert Infinity PAC.SC to SPRD PAC

A Window will popup. In this Window, navigate to the Infinity CM2 backup folder where you have your pac.sc file. Select the pac.sc file and click Open. Its going to display some info (be patient). Expect another window to select where you want to save your pac file to. [selecting location] then click on Save. It'll save here. Go back to Chinese Miracle 2 SPD and wait for the process to complete [converting pac.sc to pac] packing system might take a while [pausing recording]. Also added cache, userdata, uboot [signing]

Any moment from now, the pac file should be ready. Alright! So its done. I can see I have my pac file. That's how to convert an Infinity Chinese Miracle 2 SPD pac.sc file to a Spreadtrum pac file

No, just the files I told you about. there are 29 files in the folder and no pac.sc file. it uses 1 file called spd_prog.xml. I'll try to take a picture of them and attach.
