Wrote an "How to Flash Lumia 920" Tutorial - in German :P

[Aydon_ger]

Hi there, first THANK all of you for your helpful work in the past years. Ive reading so much on xda and it helped me always so often with my little problems. Thanks!

Now im a proud User of a Lumia 920 - and im lovin it. But at first, i have a few Problems. But i solved it (also with help from the xda-Forum, of course ^-^). And now im thinking, ok maybe i can help too. Ive see a lot of Messages written by German people here and a few from them was asking about Flashing a Lumia 920.

So i wrote a Tutorial, how to flash Lumia 920 Smartphone with a non branded german ROM (but you can use of course any other ROM-File too.) Maybe it helps - and sorry, its in German, cause its my native Language

Again - thanks all for the hints and tipps over the years - and we have a lot of things to do

// Und in Deutsch: Ich habe mal eine Anleitung geschrieben, wie man ein Lumia 920 mit einer ungebrandeten, dt. Firmware direkt von Nokia flashen kann. Das kann unter anderem bei Problemen mit einem Voodafone ROM helfen, welches ja sehr oft als Unlocked Nokia Lumia 920 in den Handel kam. Wenn ihr Probleme mit MMS oder Internet habt - lest das!

Tutorial - How to Flash (in German)


// EDIT
Ok, i grab my few english skills and try to wrote an (hopefully) understandable english Tutorial of this... dont laugh at me too loud

I have a lumia 920 which is locked to EE network.If i flash with another rom will it also work with other providers?

 

[AndyFZ1S]

No unfortunately it will only change the ROM and not Carrier Unlock the device.

 

[sonkiomi]

That's amazing! Well done.

Any German people care to carry the torch and translate it for the rest of us english speakers? I'd love to be able to flash my ATT Lumia to a Rogers one until I can get it unlocked.

 

[Gorki247]

Thank you for this guide. Using your guide I managed to flash my UK Lumia (which has the EE firmware) with the factory default GB firmware.

 

[ahg1]

Does this mean you can flash your ATT phone to Rogers firmware and take advantage of AWS 1700?

Thanks,

 

[Aydon_ger]

Thanks for your support. Glad that i can help some people. I can try to translate this little Tutorial in English too, but then some of you has to help me with the correct grammar

Anyone have success with Internet Sharing when flashing to another ROM?

planing to flash my lumia 920

i want to flash my lumia 920 i have already unlocked veriosn and global rom from italy but i want to change it because it seems the italian rom don't support at the moment 4g LTE connectivity so if i will flash RM821_CV_DE_VAR241810_yelllow the rom of germany LTE will b enabled as i contacted nokia and they told me at the moment maybe nokia didn't enabled LTE for the italian version ? thank you anyway for the great support

 

[Aydon_ger]

Please, next time use punctuation marks (no offense). I think, your question was, if you can flash an german ROM on the Lumia 920 to enable LTE in Italian, right?

Try it. The Language (italian) is still inside, so you can switch after Installing the ROM on your Smartphone. But i dont know, whether the LTE Settings in this Firmware the right ones for your country. It doesnt, you can change the Firmware back...

Dont think, anyone here can help you with this Problem. But it would be nice, if you post your experience, so it might help other people who face this Problem. Good Luck!

how do you know which firmware is unbranded? I want to flash my 820 (RM-825 code 059Q9L) to one unbranded in english (the actual ROM is unbranded but in German), but i can't identify one. BTW, I'm using Navifirm+ to find the lastest one.

 

[komugi]

Like-wise interested, which one is unbranded, and does it enable internet sharing/allow you to use it?

 

[Penecho]

I have an unbranded Lumia 920. On my package where it came from it says CV (Country version).

Manufacturer Model Name: RM-821_eu_euro2_248
Mobil Operator Name: 000-DE

And yes i can share Internet, here a pic:

says you can share with up too 8 people, and if its not used after couple of minutes it will deactivate itself...

I have an unbranded Lumia 920. On my package where it came from it says CV (Country version).

Manufacturer Model Name: RM-821_eu_euro2_248
Mobil Operator Name: 000-DE

So, the unbranded firmwares has this "000" followed by the country code were it was sold?
My NL920 that I bought it from Germany had that indicator but I flash it to an Orange UK stock firmware because I had a lot of apps that were not available with that firmware.

 

[Penecho]

I guess so, I know the german Vodafone Lumia 920 has VOD-DE instead of 000-DE

 

[Gorki247]

I concur. I have installed the Nokia default firmware for the UK on my phone and it shows the following

Manufacturer Model Name: RM-821_eu_euro1_276
Mobile Operator Name: 000-GB

Carrier: CV GB SW Variant ID 276 v03
OS version: 8.0.9903.10
Firmware: 1232.2110.1244.3003

who know at&t lumia920 can be flash the devloper's rom to unlock sim?

 

[nMIK-3]

who know at&t lumia920 can be flash the devloper's rom to unlock sim?

Yeap we should be able to do that and completely unbrand the RM-820 model (the AT&T and Rogers variants) using this method, however the "clean" firmware found on the Developer Edition Lumia 920 is not yet on the server. I personally expect that to be available once the first major update is release for the Lumia 920 from Nokia. Hopefully I am correct...

 

[Aydon_ger]

Now im flashin an Portico-ROM on my Lumia. Its branded from Orange (swiss Operator), but hasnt any looks or limitations - BUT cant use 4G.
