Hello everyone.

I accidentaly started updating real NAND thinking I was updating emunand.
I shut the 3DS down before the update was completed, but it installed Miiverse and Gateway stopped working.

This is my setup:

System Settings: Ver. 4.4.0-10U
Browser version: 1.7567

Homescreen:

Settings Screen:

What I tried:
Blue Gateway cart: Error
kJ7cCkA.jpg


Gateway 3.x .dat file web exploit: Glitch screen
2015-02-19%2000.17.28.jpg


Gateway 2.x .dat file web exploit: Error
2015-02-19%2000.15.43.jpg


Are any of these error manageable? Or am I screwed?

Also, buying a game with a native 4.4.0 < x < 9.2 update would work? Since the system recognizes itself as 4.x, an "official downgrade" is possible? Or my only choice is hardware modding and flashing my NAND backup?

Using a game card to update to something between 4.5-9.2 would be the first thing I try, followed by a hardware mod + NAND backup.

The firmware is composed by multiple packages. Each one is checked against the one is going to be installed and it will not be replaced if the one you have is newer. As such there's nothing that can downgrade you without an hardware mod

Oh boy, that sounds like a tricky situation. I wouldn't count on an "official downgrade" being possible. Try the browser exploit again with the latest Gateway 3.x launcher file, but clear cache and cookies before doing so and don't let anything load in the browser before launching the exploit website immediately after clearing cache and cookies. If the web browser wasn't updated in the partial system update, you should be able to launch the web exploit. Some people that had that browser closing error when trying to launch the exploit were able to solve their problems by doing the cookies and cache clear, so try that then report back.

I'll try to borrow a catridge like that from a friend, but I believe that what michyprima said makes sense. However, trying won't hurt

I've tried this before but I just tried it again now three times. With 3.x launcher file I actually get the glichy screen, not the closing error.
That gave me some hope because i thought that glitch screen seem like kinda exploited, but it sadly doesn't work.

It just hangs on the glitchy screen? I guess the partial firmware update patched one of the exploits needed to launch the Gateway launcher via that method. If you have a NAND backup of a firmware version that is 9.2 or less, you can get the NAND mod done and restore your exploitable NAND. Otherwise, you'll have to sell your 3DS and get one that has an exploitable firmware version.

Yes, it hangs on the glitch (always the same glitch configuration)

I do have NAND backup. My choice is then hardware mod only, then? That's sad, I'll try to find someone in my country that does this service. Thanks anyway for your help and time.

I would try first to get a game between 9.2 and 4.4. Recently, it has been discovered that systems can update via communicating with Download Play with a system with a higher FW. If a friend has 9.2 or any game under 9.2 and after 4.4 i would recommend trying either of those things before turning to hard mod.

I will try that. Just found a friend with Luigi's Mansion 2 that has a 4.5 update.
Do anyone know any other popular games with 5.x+ system updates?

Is the moré close firmware to 9.5 in terms of software. So is posible that ir can overwrite the fault parts of the damage update.

With my original 3DS I gave up on keeping it at 4.5 since at the time I could not afford to buy a Gateway. (this was long before the Ultra 3.0 release). So I tried to update from 4.x (I forget the exact 4.0 firmware it was on, but it was in the 4.x range) to 8.x or whatever the latest firmware was at the time.

The update failed near the end due to a generic error. Not sure what happened. But the setting menu no longer started up, so some firmware titles were updated to new ones that used newer encryption, but the firmware wasn't updated to the point where it actually initialized the new keys correctly.

I didn't know about the safe mode option at the time, so I used my Pokemon X game (and I know for a fact that the FW I partially updated to was newer then 6.x) and had that update my firmware. It seemed to work perfectly fine. As far as I can tell the console was updated to 6.x using the game and setting menu worked at the time. I'm pretty sure 8.x+ system settings menu would not have booted in 6.x either. But it did, so that means it must have downgraded it? Or I might have had some frankenstein system where some titles were newer they they should be for that firmware version. Either way, my second attempt to update via internet worked and it updated to the firmware version I was intending to update it to. :P

No, there is nothing specific at all. It literally doesn't matter which FW you choose.

There's some spiderhax homebrew like RegionFree that only works in the 9.x range.

From what I've heard newer revisions of the Super Smash Bros cart has the 9.2 update. Majora's Mask comes with the 9.0 update I believe. ;)

Not sure if the system update menu follows the same rules. Usually DevMan won't install CIA/Titles that are older then what they are replacing. Perhaps System Update ignores this when updating a system that had an interrupted update. For the sake of having a functional console I would think. Nintendo is not in the business of creating bricks believe it or not. ;)

The exploit might not have been patched yet. But there is a large discrepancy with browser version vs what 4.x normally has. I don't think the 9.5 update altered the browser in respect to what the last browser update was. (According to UpdateCDN, the last time the browser was updated was 7.1).


So you likely have a 7.1 browser on a 4.x system and the Gateway exploit isn't configured for that and the payloads aren't working like they should.

The safest bet on fixing this is to use a game that updates the system to 7.1 or above. (Game packaged updates do NOT come with the browser, so whatever browser version you have now you are stuck with!)

Pokemon Alpha Sapphire/Omega Ruby come with the 7.2 update. I don't know about 9.5, but 9.4 and below didn't have a browser update since 7.1. So any update between 7.1 and 9.2 will be your best bet on fixing the console so that Gateway works on it again. What version does your browser report as (found in Web Browser's settings menu). I don't know off hand, what version browser that 4.x had. But I'm sure it's not in the 1.7 range. If you have a 1.7+ Web Browser, you probably have the latest one that got introduced in 7.1.

I don't have my 3DS back from being NAND modded yet, so I can't really check what version browser that 4.x normally has.

I have I found my Pokemon Y cartridge here (forgot about having that). It updated my 3DS to 6.1.0-10U super-duper fast. The browser is at the same version and the same glitch is happening.

My browser version is 1.7567.

But your hypothesis makes sense, it's a fair bet. I found here that this browser version is found into 7.1.0-16 update. I'll try to find a game to update from 7.1.x to 9.2.

Thank you very much!
