In this video tutorial, I'll be explaining how to backup or dump a Spreadtrum Android phone's firmware
00:18
using Infinity CM2 dongle. In order to use this CM2 software, you need to have the hardware dongle
00:30
I have that over here and you need to connect it to your PC and set it up. We already have a guide
00:36
at the Forum on how to setup your Infinity CM2 dongle . check it out and follow then come back to this guide.
00:46
Connect the set up and activated dongle to the PC via the USB port. Dongle blinking red and green light.
01:05
Download Infinity box CM2 SPD. This is the software you'll be using to backup the Spreadtrum Android phone.
01:19
[Download link in description]. After downloading, you extract using 7zip. Double-click the exe file
01:48
and follow the installation process [installing CM2 SPD]. You should also have your Spreadtrum Android phone
02:22
and USB cord. You power off the phone, make sure its well charged. Keep it on standby.
02:31
You'll notice this shortcut (InfinityBox CM2SPD). I can launch it from there or go to installation directory
02:44
C:\InfinityBox\CM2SPD then you can launch (with the dongle connected). It takes a while to come up
03:23
so you just have to be patient. I should also mention that you need to have installed your Spreadtrum drivers
03:31
We have a guide and video on how to install Spreadtrum drivers on a Windows PC so check it out
03:39
Install Spreadtrum drivers on your PC before you continue if not the software won't be able to detect your
03:50
Spreadtrum Android phone. That's what drivers are for. [waiting for dashboard] Alright! its finally up after quite
04:07
Under the Settings tab, select your chipset or CPU. We already have a guide on how to find out your
04:26
Spreadtrum phone's chipset and Android version (you can use an apk) then come here to select the chip.
04:43
This phone I'll be using is an SC773x phone running on Marshmallow [selecting]. Head over to the Flash tab
05:03
I'm getting the not responding error maybe because I'm running a lot of things on my PC at the moment
05:11
[waiting for error to clear up] Now, I'm in the flash tab
05:30
Now, leave these two boxes checked then click Read Firmware [PAC]
05:54
While the phone is powered off, with the battery inside, you hold the volume down button
06:01
then you connect the USB cord to the phone (keep holding the volume down button).
06:08
[recapping]. You might expereince frequent disconnection in this tool, I'l walk you through that later
06:42
In this Window that pops up, select the location you wish to save your Spreadtrum backup
06:48
and click Save. I already have a folder called SPD dump to save my phone's CM2 SPD backup to.
06:59
I still have my finger on the volume down button because that's the boot key for Spreadtrum.
07:10
This is the popup I was telling you about (waiting for device re-connect). The device got disconnected
07:16
so I just keep holding my volume down button and I tap OK. You might get this several times
07:44
I got a range error so I'm going to have to repeat the process [repeating]. Should detect phone details.
09:58
Model, version, Build number and the rest.
then start backing up the files. Another error. I'll boot up.
10:44
I'll make this a part of the video just in case you encounter this while backing up.
10:57
[taking out and re-inserting the battery. Starting all over] It can be quite frustrating. [repeating]
12:30
Sometimes, what you need to do is disconnect your dongle, restart your PC then retry the process [repeating]
12:43
I'm going to untick the Manual Name Define option even though I'd been able to backup with it ticked.
13:11
[repeating] Okay, this is what I've been waiting for. We have backup in progress
15:24
[backing up] At this point, I can release my volume down button. Avoid disconnecting from the USB cord.
16:06
[backup in progress] This is going to take a while backing up system [pausing video recording]
16:41
Alright! We're almost done [99% at system.img] Done! What you have here is the path backup was saved to
17:16
Mine is located n the Hovatek folder. I want to stress something very important here. This format
17:47
is customized to CM2 SPD so you need to flash back using CM2 SPD. Its not a regular PAC file
17:59
which you flash using Research Download or Upgrade Download tool. That's how to backup
18:15
or dump a Spreadtrum Android phone's firmware using Chinese Miracle 2 or CM2 SPD software

[@sf8262]

hey i saw you posting about the Hisense a5 pro. Have you managed/tried to extract the firmware from it? There are pac and FDLs available from another device that also uses the T610, so it may be possible using that. Once I get the phone I plan on testing out the Research Download tool, assuming the extracted files aren't posted by someone else by then

[@HovatekTV]

We tried it, it didn't work

[@johnrobot4652]

Any method to dump sprd firmware without dongle (I have only PC)?
