Need help finding the seed to my first ever world.

In 2020, my first ever minecraft world got corrupted, and I lost pretty much everything including the seed, which reset to 0. This was on the Xbox 360 edition of the game, and I really wanna see if I can try to revisit it since it has immense sentimental value, and this is kinda the only way I have left to get help with finding it.

I should clarify some things to help narrow it down. The world was created around august of 2014 on the Xbox 360 edition of the game, however, the game had only been updated to TU11 on my console, meaning this seed was created with TU11 world generation. There could be some leaneancy in the map as it might not be totally accurate (being 6 years since I've seen it) primarily with rivers and exact land shapes. The more inland areas of the Northwest region specifically I never really explored. I tried my best to replicate how it looked, but there may be errors. Hopefully it's close enough where it could be found. I think I might still have the tiny icon of where I last saved before It got corrupted, so once I find that, if it's any help at all, I'll post an update.
Really hope this could lead to finding it again but I won't be pressed if it doesn't. Thanks
