In this video tutorial, I'll be explaining how to backup and restore NVRAM to a
00:15
Spreadtrum Android device using NCK box Spreadtrum Module. First off, You need to
00:21
have the NCK pro box hardware and You need to have set it up. We have a guide for that. You
00:26
also need to have installed the Spreadtrum USB drivers. We also have a guide for that and
00:31
of course You need to have the Spreadtrum phone which you want to backup NVRAM
00:35
from or restore to. Now, just in case you don't know what the NVRAM is
00:38
for, NVRAM controls your phone's radio; things like your IMEI
00:42
Your Bluetooth address, Wi-Fi address and the rest. So if You have an NVRAM
00:48
problem, Your phone might not be able to detect SIM cards due to the invalid IMEI or You
00:53
might have Bluetooth or Wi-Fi problems. In such a case, You need to backup
00:57
the NVRAM from a working phone and rewrite to Yours. That is what this guide is
01:02
about. Now, once you have these in place, You need to also have installed the NCK
01:05
box Spreadtrum module as I have here. Run as Administrator. We have a guide on how to
01:11
install the Spreadtrum module for NCK box so ensure to check out that guide and download the
01:20
module. Now, what you want to do is just to wait for
01:22
the module's dashboard to come up and of course Your box needs to be connected
01:27
to the PC but not the phone yet. Alright! Great! So the dashboard is up. Now, what
01:34
You want to do is to come under the Flash Mode Utils although You can also do the
01:40
same thing under the Diag Mode but that will be in another tutorial. This tutorial is about the
01:46
Flash Mode. Now what You want to do is to come under the Flash Mode tab and you select
01:53
your phone's CPU. Now, we have a guide on how to find out your phone's chipset so make
01:58
sure You follow that guide. For this particular phone I'm using, its Generic CPU so I'll
02:02
just select Generic here. Its actually an Innjoo phone (Innjoo Halo) so I'll just select
02:08
Generic there and then for the chipset, this is what the phone's chipset is. So
02:14
under this Job section, what You'll want to do is to select Backup NVRAM. I'm backing
02:22
up from the working phone in this case, although its the very same phone I'm
02:25
backing up and writing to in this tutorial but its just to show you what its going to be
02:30
like. Now, we're backing up the NVRAM first, and we have the working phone
02:34
standing by. So what You'll want to do is select this option that I have here and
02:38
then You click on Do Job. Now, at this point, What You'll want to do is to power off the Spreadtrum
02:44
device, still with battery in, then You hold the volume down button
02:48
alright? Then connect it to the PC via
the USB cord. Now, for this particular phone
02:55
I am using, its actually the volume up
button. Its a very weird phone, so everything
03:00
is the other way around for this phone. OK, so I have USB Not Recognized. I'm
03:08
going to have to abort. When
you have something like this, You have to just take out
03:13
and reinsert the battery OK? That's what you do. Make sure you are holding the
03:18
volume button correctly (You're not pressing both). So I've taken out and reinserted the
03:23
battery, I'm going to repeat the procedure and I'm connecting now
03:39
still seem to be running into this. Alright! so what I can do now is to just close
03:45
this box. I close the tool, I eject the smart card (that's the box), I reinsert
03:58
then I'm going to rerun the tool. Well, I could as well cut out this part from the
04:06
guide but its very important You also see what I'm encountering so You know
04:11
what to do when You're in a similar situation. So I've taken out and reinserted the
04:15
phone's battery. That didn't seem to help.
Next up, I have closed the tool. I've disconnected
04:21
and reconnected the box and I'm relaunching the NCK Pro
04:29
Spreadtrum module. So I have it up. I come here, I come under Generic. Here, this is
04:38
phone's CPU and then I select Backup NVRAM, click Do Job.
04:47
Alright! Holding the volume up button..Its supposed to be volume down but this particular phone is actually
