PLZZZZZZZZZZZZZ!!!!!!!
Please don't. 10 minutes is an unreasonable amount of time to expect a solution to your problem.

I believe It's a known issue associated with converting a MH4G save to MH4U, but there is no known fix to my knowledge.

Where did you find the instructions to convert? This glitch should have been mentioned along with the instructions.

"Prepping the MH4G data for 4U"

Unfortunately, we cannot simply inject our MH4G savedata to MH4U as the localisation team decided to change things up a bit. Namely it’s just one change but it breaks your guildcard if we don’t fix it: the character limit for your guildcard description text which is now 36 chars longer and therefore takes up 72 bytes more space (due to the game using UTF16-LE encoding).

By the way, the localized version does not support Japanese characters, so make sure to fix your name or whatever else important you use Japanese chars in in this step.

If you haven’t acquired plain text savedata yet, decrypt the files (pointless to go into detail since I can’t give out the tool and it’s not released yet). MH4G/U uses an additional layer of encryption for savedata and extdata which no other 3DS game I know of (except for MH4) does.

Open user1/user2/user3 in your Hex Editor of choice and jump to offset 0x12738. Insert 72 bytes of nulldata. Jump to 0x139F8 and you should see some dummy data. Remove 72 bytes of the the nullspace before the dummy data to make up for the changes. Save your file. There we go! Your user savedata is now fixed and almost ready for 4U.

The same problem applies to the card1~card3 files from your extdata. These are the only files from extdata you need to decrypt. Since you may have lots of guild cards stored there, it might be worth wrapping up a little script (pretty easy, start at 0x148, insert 0x48 bytes, move by 0x1200, insert etc.). I did it manually since I only had a few cards anyway and had to verify the guildcard size is always identical. Don’t forget to cut out the added 0x48 bytes at the end of each guildcard block.

To wrap up this step, encrypt user1~3 and card1~3.

i hope that help u..
coz i dont understand it at all.. i too convert it successfully i can go to elder hall, but my guild card is as broken as yours..

Hi, if I just want to convert my mh4u save to mh4g then back to mh4u, do I need to fix the guild card? I just want to try the item duplication in mh4g then convert back to mh4u. Will the guild card be broken either way? Thanks

Probably not relevant anymore, but I had no problems at all converting the EU save to JP, and then back to EU. Elder Hall works just fine, and the guild card wasn't screwed (shows exactly as it should).
Think anything might happen in the long run?

Could you explain us how you did it?, aren't the saves encrypted?. I read you need to hex modify the saves, but then there is the encryption problem...

Probably like this :
1- Export EU/US save with SDF
2- Create new save with JP version
3- Export JP save with SDF
4- Overwrite user1 file from EU/US exported save to JP exported save
5- Import back JP save with SDF

I thought that at first too, but what about

That would cause problems for sure.

I tried it, and at least in MH4G my guild card has the same problem as OP. I'll try to transfer it back and see if the problem persists.

EDIT: It does, I could keep all duped items. But my guild card has incorrect weapon usage values and some awards were deleted.

I ran into this same problem as well. It changed me into g3 when I was gold crown but I retain the ability to go into crown quests and my guild card is now like OP's. Unsure how to fix this.

Yeap, I converted a save data of 4U>4G>4U, and turns out that my guild card has incorrect weapon usage values as well. All other statistics like quest counts were intact though. Any updates or tips to solve this? There were a few that apparently had their guild card intact.

Edit: I forgot to mention that I used HxD to look through clean saves of 4U, 4G, and the converted 4G>4U save data, but I couldn't find any of the mentioned null and dummy data offsets.
