See the video tutorial below or at https://youtu.be/tP12NGPxS7MQuote:In this video tutorial, I'll be explaining how to backup or dump a Spreadtrum Android phone's firmware using Infinity CM2 dongle. In order to use this CM2 software, you need to have the hardware dongle I have that over here and you need to connect it to your PC and set it up. We already have a guide at the Forum on how to setup your Infinity CM2 dongle . check it out and follow then come back to this guide.
Connect the set up and activated dongle to the PC via the USB port. Dongle blinking red and green light. Download Infinity box CM2 SPD. This is the software you'll be using to backup the Spreadtrum Android phone. [Download link in description]. After downloading, you extract using 7zip. Double-click the exe file and follow the installation process [installing CM2 SPD]. You should also have your Spreadtrum Android phone and USB cord.
You power off the phone, make sure its well charged. Keep it on standby. You'll notice this shortcut (InfinityBox CM2SPD). I can launch it from there or go to installation directory C:\InfinityBox\CM2SPD then you can launch (with the dongle connected). It takes a while to come up so you just have to be patient. I should also mention that you need to have installed your Spreadtrum drivers We have a guide and video on how to install Spreadtrum drivers on a Windows PC so check it out Install Spreadtrum drivers on your PC before you continue if not the software won't be able to detect your Spreadtrum Android phone. That's what drivers are for.
[waiting for dashboard] Alright! its finally up after quite Under the Settings tab, select your chipset or CPU. We already have a guide on how to find out your Spreadtrum phone's chipset and Android version (you can use an apk) then come here to select the chip. This phone I'll be using is an SC773x phone running on Marshmallow [selecting]. Head over to the Flash tab I'm getting the not responding error maybe because I'm running a lot of things on my PC at the moment [waiting for error to clear up] Now, I'm in the flash tab.
Now, leave these two boxes checked then click Read Firmware [PAC] While the phone is powered off, with the battery inside, you holdĀ the volume down button then you connect the USB cord to the phone (keep holding the volume down button). [recapping]. You might expereince frequent disconnection in this tool, I'l walk you through that later In this Window that pops up, select the location you wish to save your Spreadtrum backup and click Save.
I already have a folder called SPD dump to save my phone's CM2 SPD backup to. I still have my finger on the volume down button because that's the boot key for Spreadtrum. This is the popup I was telling you about (waiting for device re-connect). The device got disconnected so I just keep holding my volume down button and I tap OK. You might get this several times I got a range error so I'm going to have to repeat the process [repeating]. Should detect phone details.
Model, version, Build number and the rest. then start backing up the files. Another error. I'll boot up. I'll make this a part of the video just in case you encounter this while backing up. [taking out and re-inserting the battery. Starting all over] It can be quite frustrating. [repeating] Sometimes, what you need to do is disconnect your dongle, restart your PC then retry the process [repeating]
I'm going to untick the Manual Name Define option even though I'd been able to backup with it ticked. [repeating] Okay, this is what I've been waiting for. We have backup in progress [backing up] At this point, I can release my volume down button. Avoid disconnecting from the USB cord. [backup in progress] This is going to take a while backing up system [pausing video recording]
Alright! We're almost done [99% at system.img] Done! What you have here is the path backup was saved to Mine is located n the Hovatek folder. I want to stress something very important here. This format is customized to CM2 SPD so you need to flash back using CM2 SPD. Its not a regular PAC file which you flash using Research Download or Upgrade Download tool.
That's how to backup or dump a Spreadtrum Android phone's firmware using Chinese Miracle 2 or CM2 SPD software
(10-09-2020, 06:10 PM)Dilone61 Hi, We tried this method but ended up with individual files likeboot.img, system.img, userdata.img and so on instead of 1 pac.sc file. So, is there a way to combine it into one .pac file? if you try to flash it, it picks on 1 file called SPD.prog.xml and it loads all the files, then it flashes successfully. How can I combine the partitions to get 1 single .pac file? thanks.
