I have successfully done this in my Lumia 830 running WP8.1 Update 2 (OS version 8.10.15137.148 Firmware Version 02040.00021.15063.02002)

I have mentioned these tips some where else in other forum as well.
Posting it here for the benefit of all who need it.

And I got a doubt. If I download 1 Gb map data to sd card and later reset my phone. Is the map data already stored in my sd card reusable or should I download again ?

 

[binnyandrews]

The maps that are downloaded to SD card are reusable.
After the hard reset, just follow the process up from #1 to #18 and then go to Storage sense> SD Card>Maps> Manage> check for update.
It will download 1MB of data and you are done.

I have a Lumia 820, OS version 8.10.14234.375, Firmware 3051.50009.1451.1002 and tried the tool. I proceeded according to the tutorial but maps are not save to SD-card, only to phone memory. So the tool doesn't work for me.

 

[binnyandrews]

Have u tried reading the key Useextendedstorage. Is this key value 00000001

 

[malvo26]

Yes, in Useextendedstorage the value is 00000001. I guess the OS version 8.10.15137.148 (GDR2) is necessary for this to work. I'll install GDR2 first to see if it works.

 

[binnyandrews]

What about the other two keys

 

[Gaurav Tyagi]

Commenting to use this method later.

 

[malvo26]

I installed GDR2 and have OS version 8.10.15137.148 and followed the instructions completely with the key values as indicated but no dice. Even after soft resetting it doesn?t download maps to SD card.

 

[binnyandrews]

Have you checked if your sd card has a folder MapData.

 

[Karthik Sampath]

Once downloaded maps can be used in other device?

 

[Abrar ahamed]

Nice trick ....

 

[malvo26]

sd card does not have a folder MapData. I created the folder on the sd card and downloaded a map but it still goes to phone memory.

 

[dsvictor]

Searching for this method..

I haven't tried it yet. My guess is it wont work as the downloaded maps has a unique id (unique_id.txt).

sd card does not have a folder MapData. I created the folder on the sd card and downloaded a map but it still goes to phone memory.

Strange - I tried it in my L820 and it ca not even read the value.
OS 8.10.15116.125
FW 3051.50009.1451.1002

But its working flawlessly in L830.

If a simple tool is available, we don't need to spend so much precious time and energy. Hope you are up to date yourself.

 

[binnyandrews]

Tried it in Lumia 435 and it is working
OS 8.10.15116.125
FW 0206000000.015056.21002

I may try this in L1520 and update in a while.
