Quote:In this video tutorial, I'll be explaining how to flash a Spreadtrum Android phone using Infinity box CM2 SPD. Now, for you to flash your Spreadtrum phone, you're going to of course need the box and the .pac or .pac.sc which you want to flash. Now, this is the CM2 SPD software which you'll later install and this is the pac file / format which you can flash with any tool.

This is the pac.sc format which you flash with only Infinity box. Install the Infinity CM2 SPD. Have the dongle connected to your PC. [installing CM2 SPD] Before I forget, you need to install Spreadtrum drivers. We have a guide at the Forum on how to install Spreadtrum drivers to your PC. Follow that guide, see the video, install drivers if not this is not going to work because drivers enable your phone and the PC communicate.

Now, I've installed the CM2 SPD. I'm going to go ahead to launch it. This often takes a while so be patient while the Infinity box CM2 SPD dashboard comes up. Alright! The dashboard is up. [re-positioning] Now click CPU (under Settings), select your phone's chipset. We have a guide on how to find out the chipset so check out our Forum for that guide. Next, click the Flash tab then click the PAC button. A Window should popup. In this Window, navigate to the location where you have your pac or pac.sc file.

I should mention that the pac.sc is a dump which is exclusive to Infinity box so you can only flash that back using Infinity box but the .pac format can be flashed using any Spreadtrum flash tool like Miracle box, Research Download, Upgrade Download and any other SPD flash tool. What I have here are both the .pac and .pac.sc format. We have a guide on how to convert .pac.sc to .pac file.

I think I'll just select the pac format since that is more universal. Once you select the pac or pac.sc depending on which you have, you click on Open. Chinese Miracle 2 SPD will read the firmware's details then you can go ahead to click on Flash. (red text). You'll see ====Wait for phone..Now, power off the phone, still with battery inside, hold the volume down button then connect it to the PC. You should have detection. [phone detected] Next up, you should have the partitions flashing [flashing].

It might take a while because of the system partition which is usually heavy. [pausing video recording] Alright! and I have Elapsed with the time it took. Now you can disconnect and power up the phone. That's how to flash a Spreadtrum pac.sc or pac file to a Spreadtrum Android phone using Chinese Miracle II SPD module.
