Lumia 1520 Product Codes

[anon(6098928)]

Hello all. Quick question: Just curious to know if there is a list of all Lumia 1520 variants? Keen to better understand the version of 1520 I now own (having bought one secondhand).

Most of the difference is in the radios. Nokia Lumia 1520 - Full phone specifications

The RM-940 for AT&T is the big deviation. It offers only 16GB internal storage on most with a rare 32GB upgrade only in black. ALL AT&T models have Qi Wireless Charging stripped out. Then PowerMat charging is added in, but requires a jacket. AT&T models have the 3 contact pins on the back for the charging jacket and no other 1520 has that.

I was about to ask the same thing. I'm surprised no one here has made a sticky on the various 1520 variants with which networks they best work with. From what I can tell the only one that works well with T-Mobile is the RM-938 is that correct?

Nice!!! Except it skips RM-938 all together.

​Sure... Until just a couple weeks ago...

The issue with a carrier unlocked AT&T 1520 not working optimally on T-Mo is the missing 1700 MHz on the 3G radio which you want to have in any area where T-Mo does not offer LTE... Without 3G @ 1700 you fall down to EDGE when LTE coverage drops out.

That may now be fixed. AR2186 has a workaround how-to: http://forums.windowscentral.com/no...-1520-t-mobile-aws-3g-hspa-band-4-1700-a.html Seems the 3G @ 1700 MHz is on the radio, but disabled. AR2186 shows how to use Field Test to activate it and then you are golden.

FWIW, that doesn't even mention the 938 (1520.3)

I'm using the AT&T 1520 on T-Mobile and have no problems. I picked up a brand new AT&T 1520 from ebay for $350 unlocked. Couldn't justify spending $200 more to get the RM-938.

Also I know my link doesn't specify product codes for the RM-938, but I couldn't find them anywhere.

Have you tried to enable 1700 WCDMA yet?

Is it possible to install a RM-937/38 firmware on the AT&T that it's RM-940? Heard that Denim has appeared in CV Finland and i want to try it.

 

[Loco5150]

Demin has appeared for 1520 in Finland? Wut

 

[Loco5150]

Nope, not for me at least.

 

[Loco5150]

Scratch that, just got Denim to my L1520.

I went to the service menu and enabled it there. However I live in a refarmed area so I have no way to verify that it is actually working.
But the thread that explains the workaround has a couple posts saying that it works.

 

[RumoredNow]

I'd leave that 1700 WCDMA active for traveling. Glad you tried it out. Thanks for the update.

So anybody knows if i can flash another firmware in my AT&T 1520?

You could try, but it will brick your phone at worst and render your radio useless at best.

Because the hardware is different I doubt the firmware for the RM-938 would even work.
If the 1520 is anything like other AT&T windows phone it will have the firmware locked down anyway so it can't be flashed.

Who was the seller on Ebay? The only AT&T 1520 unlocked ones I saw were I think store displays or refurbs. I'm on the same boat too can't get myself to spend 500+ on the device that's already a year old. Also are you able to do Tmobile's wifi calling?

​Only T-Mo branded phones can use the T-Mo WiFi calling App. Sorry.
