Video Tutorial
Quote:In this video tutorial, I'll be explaining how to use Research Download tool. You'ld usually use this tool when you wish to flash a Spreadtrum-based phone and you'll need to have your drivers which I have here and your Research (Upgrade or Factory) Download tool of course and your PAC file. Your PAC file is your stock rom. In the case of Spreadtrum, its in packets. You need to have your PAC file. I'll be using Itel 1452 for this video tutorial and you'll need your Spreadtrum phone.

First thing is to install drivers In my previous videos, I explained how to install VCOM drivers for the Mediatek and the Spreadtrum drivers but just for those who might have missed the video, I'll be taking you briefly through how to install the drivers in this guide just to make it easier for you so we have a start to finish approach. You could also visit our website to check the video or guide yourself so you can manually install the Spreadtrum drivers yourself if you ever need to.

I have everything I need. I'll install my drivers. I have the SCI driver; the Jungo and the Spreadtrum (USB) drivers so you just open a folder. The particular driver you'll install depends on the kind of PC you have. If you're using a 32 bit, you'll of course open this (x86) folder. I'm using a 64 bit PC for this tutorial so I'll just open this (x64). Just double-click this (DPInst). Now, before you proceed with this, its very important that you disable signature verification on your PC.

I'd shot a video on on that. You can also check our website on how to manually disable signature verification on Windows PC ensure you do that because if you don't, you might not be able to install unsigned drivers. What you just need to do is click Next. I'll be installing both drivers using this same approach My drivers were successfully installed so I just click on Finish. Next up is to install the other drivers SciU2S 64 bit (based on my PC). Just run this, click Yes to confirm and just proceed.  That's all

If you encounter any error at this point, what you just have to do is manually install the drivers you can check our website for how to manually install Spreadtrum drivers, you can also see the video Drivers installed. Next is to launch Research Download tool. I run as Admin just to avoid permission issues Click Yes to confirm. OK, we are open here. At this point, you'll want to disconnect your Spreadtrum phone If the battery is removable, remove the battery and slot it back in just to make sure that the phone is switched off.

At this point, my Research Download tool is up, you'll want to load the packet (file). Click on Load Packet In the Window that pops up, select the pac file. Its very important you do not flash the pac file meant for a different model to your phone if not you're going to have serious issues. Flash the pac file for your model so I'll load this pac file. Its quite important you're patient with this because (I have not responding) It could be quite slow depending on your PC type. Now, this is loaded.

I'm ready to go ahead with flashing all I have to do is just click this Start Downloading button but sometimes, you might encounter a couple of errors so I'll just take you briefly through some things you can do to avoid some errors You could get the NVdata failed error. If you ever come across that, all you need to do is just come to your Settings - Backup. If you're having the NVdata or some kind of NV error, untick all these items then click on OK. When next you flash, you'll not be having NV errors.

You can also select which items you wish to flash In this case, the FDL 1&2 are compulsory for you to flash. You might selectively flash some items In this guide I'll not be flashing all items. I'll be flashing just cache to avoid any problems although the pac file is meant for my phone, I just want to make this flashing a lot faster by disabling all other items except cache so I have a fast flash.

If you intend to flash all the files, you don't need to some here, just go straight to Start Downloading but in my case, I want to selectively flash. In a case where you have pattern lock maybe the owner forgot his pattern or something. What you'll want to do in that case is just flash userdata In that case, you would have your fdl files ticked and userdata (then maybe cache) ticked.

Those 4 files. So you just go ahead with flashing. Basically, you can flash only what you want like recovery system.. tick whatever you want to flash. I have my 2 fdl files and cache ticked so I click OK. Remember this part is optional so you don't have to go through all that setting. I have everything set up, I'm ready to flash. Everything is good to go. Next, click Start Download and you'll have progress bar saying waiting At this point, remove your battery and slot it back in (if removable). Make sure the phone is switched off then connect the phone to the PC while its switched off (battery inside).

Ensure the battery is well charged If after connecting to PC, all you still see is waiting (i.e nothing is happening). It likely you didn't install the drivers correctly so you might want to go  back to that step or your port is faulty, might want to change your port or in some cases, you might need to hold down the Volume down button while connecting to the PC but for some phones, once you just connect directly, it starts flashing. For phones like this one I'm holding you need to hold the volume down / decrease button while connecting to the PC for flashing. [connecting]

My flashing has begun. Alright! My flashing was successful, my phone is going to reboot. So basically, that's how to use Research Download tool. You could decide to flash all the files and come straight to Start Downloading (I can click Stop now) or selecting which files you'll flash by going to Settings then unticking any unneeded item. That's how to use Research Download tool
