Hacking EZ Flash Junior GBC issues ("Micro SD initial error!")

[Jayro]

it's not even letting me load into the software, so updating or downgrading isn't possible

You don't have any other SD cards laying around that you could temporarily use for a flash?

New Micro SD card didn't work. I could try cycling through different formats and see if one works, but I think I'll need a replacement flashcart

use this

I've tried two different micro sdhc cards(both FAT32, 32kb allocation, one 16gb, the other 32gb), both FW4 and FW5, both are being detected as a primary and not logical, and both are MBR, not GPT. Nothing has gotten my EZ-Flash Junior to work. The error message is "Micro SD Initial Error". I have an original CGB-001, with CPU-01. Can I contact you to get a replacement flashcart? I bought it and received it within the last week.

what os are you using? and which program to do the format?

if you want a replacement, I think you have to find the dealer which sold the card to you. I can not do the warranty service directly.

I found out just tonight that I had to use my 1GB Mini SD card formatted to Fat16 64KB clusters worked to flash my EZ-Flash IV. 8GB+ SDHC cards kept giving me a black screen when holding R.

Windows 10, and the format tool in the file explorer.

Either I'm believably unlucky and got two flashcarts (ordered a replacement and it arrived very quickly) that don't work, or the issue is with either the cart reader on my gbc (though I doubt it since it starts ez-flash initialization sequence), or the issue is with the formatting on the micro sd cards. I've tried all allocation sizes available on FAT32, NTFS and exFAT. I know someone mentioned that FAT16 worked for them, but I'm not sure how to format to FAT16. I'm just stumped and not sure how to get the darn thing to work.

I'm using the windows format tool, like shown in the tutorial video on the EZ-Flash website.

Since you have two Jr, and they are acting as same. the issue will be focused on the SD card format or the SD itself.

The best compatible SD with JR is the sandisk red 32GB. I will suggest you to try this one.

and the format tools, you can use the official SD format tools(aka Panasonic formatter tools) too.

This is the sd card I currently have: https://www.amazon.com/Sandisk-Ultr...1&keywords=sandisk+16gb&qid=1612906819&sr=8-3 is this a sandisk red?

It is a sandisk red. If the SD card is also fine, I would need to ask about your game console.

Did you mod your GBC? what battery are you using?

Kirkland AA batteries, no mods.

Kirkland Alkaline AA batteries, no mods.

no idea for now. strange!

One thing I just thought of is that the battery contacts on this gbc are slightly damaged due to corrosion. Could it be that improper power delivery is the root of the problem? So the console isn't getting as much power as the EZ-Flash needs? UPDATE: Completely cleaned the battery contacts and it didn't seem to help.

You have to confirm the point of occurrence of the problem, whether it was before or after upgrading the RC firmware and kernel on the official website.

If your card still boots normally, I suggest you downgrade to FW4+Kernel 1.04.

thanks for the reply and yes i did downgrade back to 4 and up to 5 both similair results. i can easy power on the gameboy color and start the cartridge but after i choose my gbc folder it crashes shows some artifacts and strange numbers and letters.

i think it has something to do with the rtc game i used and now my card is playing crazy

can i delete somehow the save battery state? i mean not my SAVER folder ( itried that) like full reseting the cardrigde? after that i will atleast play some none rtc games and gb games formyself and waiting for a full working upgrade for rtc games...
cause the card is now useless for me and thats makes me angry i even stopped my playtrough cause of all this
