Intro
Okay here is a Noob proof tutorial by me base on what I have read on various threads.
Note: That I do not have gateway yet, but want to make sure that everybody include myself get this right.
Note: This is a collaboration work by members not my professional guide.

Warning!!!!! : This is only base on what I read, it still need to be modify by other member.
Edit: people are reported that they are successfully updated their system through these steps.
Warning!!: Update do not add any features to the system until GW team update it. Always check the Firmware version before you attempt to upgrade!
Note!!!!: This is a beta release of Gateway 2.0b, Something may goes wrong even if you fellow these steps !!! If you do not wish to risk your system just stop at step 12 and wait for Gateway to release a stable version of FW.
Note!!!!: There is really no need to update the firmware to 7.1 right now other than being able to play cartridges that require 5+ firmware.

Disclaimer: Do it at your own risk
System info.
The system is brand new 3DS XL with FW: 4.4.0-10u
Note: Any FW between 4.1-4.5 would work. You do not need to update to latest FW: 4.5 to use Gateway 2.0b

Steps
NOTE: For the old Gateway user just skip to step 7th
Edit:If you do not wish to upgrade your emuNAND just stop at step 12th
1st: boot up the system setup username, turn off wifi, skip WIFI setup, then go to setting check the FW ver.
2nd: Connect your mircoSDcard, then Copy files from Blue Card (R4i) folder to the Root of a fat 32 formatted
Micro SD Card (small SD card not the one in your 3ds)--> put the Micro Sd Card in your blue gateway card--> put it in your 3DS.
3rd: Run Gateway installer
4th: Press A to install then Press A to power down or Home to return to main menu
5th: Copy Launcher.dat from GW Release to the root of the SD card from the 3DS
6th: Boot the Gateway mode by going through Setting-> other setting -> profile-> Hold L-> Nintendo DS profile.
Note: press L is to launch GUI (gateway user interface)with out L your 3ds will boot directly boot in to Gateway mode (regular 3ds menu where you can play rom.
7th: In GUI select the "BACKUP SYSTEM NAND" option (need at least 1 GB free space of 3ds SD card)
8th: Turn off the system- > takeout your 3DS SD card backup your newly created .NAND on your PC.
9th: After copy the file put your 3DS Sd card back into your 3DS.
10th: Boot up GUI-> run the Format emuNAND. Not sure what will happen to the system it may be power off or it may just boot into gateway mode.
11th: close your 3DS and takeout your Sd card-> on your computer drive you will see that half of your memory space is gone.
12th: put your 3DS SD card back in to your 3ds---> Boot up GUI again this time run Gateway mode.
Edit: you should also move either the icons around, or create a folder, to make the emuNAND visibly different from the realNAND. by MadButch
13th: Go to setting check "GW3D" label in the system version number in the System Settings application.
14th: Enter into WiFi settings and set up a connection. Accept the TOS (term of services) Note: some people report that they accidentally update their readNAND instead of their emuNAND after setting the wifi connection.
15th: reboot your system go to setting internet setting Deleted your wifi setting. (may not need to do this step) . gix222 noted that the system does not remember your WiFi setting from emuNAND in realNAND. So just skip this step.
16th:Turn off your 3DS--> reboot 3ds in to gateway mode again.-> go to setting check again that GW3D" label in the system version number. Warning!!!!!!!: DO NOT exit system setting when you see the GW3D in ront of the firmware version, before updating the firmware by aiat_gamer
17th: Go to other setting--> system updates. (cross your fingers) your system will shut down after the update is done.
18th: boot up system go to setting check that you still in fw 4.x . then you done

Please help me edit this post, I'm not expert myself, but want to make sure that this clean the confusion.



Thank you for reading.

Will Gateway ever look at getting their card to work with 3DS consoles that already have the latest Official firmware on their device?

My god this is killing me

 

[benzs129]

Nobody know but they said they are working on something. As they claim that they already know 3ds as if it was a text book

I have no Gateway but this guide is accurate. Did the exact same things including reboot after Wifi setup. Did this days before this guide and it worked for me.

Steps I did on 4.4.0-10E:

- did SD Card backup
- installed GW_INSTALLER.NDS and copied Launcher.dat
- launched GUI
- did NAND backup (3 times), copied them to PC too
- couple of reboots later: format emuNAND
- launched GW mode and made sure GW3DS is showing at firmware version
- set up Wifi
- rebooted (was not necessary i think)
- launched GW mode again (GW3DS showing)
- updated FW in settings menu
- reboot
- tried Luigi's Mansion (asks for 4.5 update as expected)
- launched Classic Mode (now on EmuNAND)
- tried Luigi again (working, no update message)

did you try the backup (downloaded version) of the Luigi or the official cartridge?

i have questions running on my mind.I will be glad if you elaborate these update questions of mine.

1-I am on 4.2 atm, is there a way to update my console to 4.5 without an official cartridge?

2-OR is there a need for doing the update to 4.5?(I am sure the gateway will still work on 4.2 but I am not sure if it is going to ask me to update when I am playing a backup version of the game.)

3-If I put an official nintendo cartridge that requires 4.5 update and if I go on with the update, will it ruin the working gateway setup?will gateway still work or do I have to exploit it again?

4-I think I have to select the classic mode for the games that require more than 4.5 firmware right? If there is an update file in the cartridge does gateway skip that update ?

0. In this post I was talking about the retail cartridge.
1. Yes you can use Gateway's Launcher 1.0 and a Backup to update to 4.5.
2. No need to update.
3. It works the same as 4.2, only difference: you are on FW 4.5 now^^ What messes with the exploit is, when you play a Nintendo DS game/rom.
4. Classic mode is for retail games, and yes GW will skip the update (except Launcher 1.0).

Hi, I'm new here

(sorry for my bad English, especially my grammar), I bought my Gateway 3DS 3 months ago. Just now Gateway 3DS Omega 2.1 released, I want to format my SD Card, and replace my "old gateway launcher.dat" to "Gateway 2.1 Omega launcher.dat". So I try to format it from Gateway mode on "format emunand" command. And when I plug in on PC, I found My SD Card loss it original capacity.

how can I restore the SD card to original size ? I mean, my SD card capacity is missing it max capacity, I just want to restore it become it original capacity. And it can't be formatted from PC as well. It say my SD card is "write protected". And I can't replace my launcher too, it said "write protected". But when plug into my 3ds, it still can write, and save my data (such as photo, voice record, etc) to my SD Card from 3ds.

*There's nothing wrong with my SD Card lock switch, it's on unlock position.
*I can deleting my photos, and voice record which is saved in my SD Card from my 3ds, but I can't delete it from PC, I only can copy them from SD Card into my PC
*My original SD Card capacity is 2GB, and now become 851MB
*In Windows Disk Management, my full original capacity of 2GB is still detected, but half of it is detected as "unallocated" partition
*I already back up my old emunand with necessary folders I found in my SD card

thanks problem solved, that was because my SD Card lock switch is sensitive, and i try to stick it with tape to prevent it from moving http://gbatemp.net/threads/3ds-noob-paradise-ask-questions-here.359035/page-95

After configuring my wifi network under emunand, I rebooted and sysnand did remember my network while I never configured it under sysnand (brand new console). So I deleted it, booted in GW mode and the wifi was back on. The console is updating at the moment.

15th: reboot your system go to setting internet setting Deleted your wifi setting. (may not need to do this step) . gix222 noted that the system does not remember your WiFi setting from emuNAND in realNAND. So just skip this step.

If you exit out of settings after you setup the wifi then it will be saved in real nand. I think if you power down from settings then you can skip it.

I exited out of settings before I powered off and then I had to delete wifi settings. So just be careful everyone.

Since this tutorial implies that you dont need a red card to update, I think we should add this point.
I tried updating to 9.x without having a red card and can't boot emunand.
