Vital Bracelet BE Not Updating | Digitama Hatchery | Page 1

#

I’m not sure if anyone may be able to help. I’ve tried updating my vital bracelet 3 different times now with 3 different SD cards, a Sandisk 32g, a Kingston 32g, and a Kingston 32&4g. I have not had any luck getting it to update. I have the Vital Bracelet BE Black and Gold Version. My husband also has a Vital Bracelet BE and has had no issues updating his.

#

Sorry, the second Kingston is a Kingston 4g.

#

did you just take the same file and use it to patch yours?

carmine warren May 24, 2023, 11:34 PM

#

Double check the version that's actually installed. If it's already 2.0.A, it won't let you reinstall

hardy gyro May 24, 2023, 11:43 PM

#

My VB still has the factory version on it, so version 1.0A. We did use the same file to update.

carmine warren May 24, 2023, 11:45 PM

#

Odd. It should work if you're just using Bandai's update. Did you get waiting before the error?

hardy gyro May 25, 2023, 12:13 AM

#

I tried both the Bandai update and Cyanic’s mod.

hardy gyro May 25, 2023, 12:15 AM

#

We were able to update my husband’s VB without any issues, it’s just the Black and Gold VB that’s giving the error.

pale reef May 25, 2023, 12:16 AM

#

but did you get the "waiting" screen before the error?

hardy gyro May 25, 2023, 12:18 AM

#

The waiting screen did not appear when we tried either of the two updates.

carmine warren May 25, 2023, 12:19 AM

#

OK. I would say, first take a card that you know works, then delete all the update files from it, and download a fresh copy of the update try that, see if it works. If it doesn't, really double check whether it did update already

pale reef May 25, 2023, 12:20 AM

#

actually yeah, are you using the exact same card that worked with your husband's BE?

hardy gyro May 25, 2023, 12:22 AM

#

We will try that and see if it works. I just got home and double checked. I have version 1.0B. I’m not sure if that makes a difference.

dense compassBOT May 25, 2023, 12:22 AM

#

@hardy gyro has leveled up! (0 ➜ 1)

pale reef May 25, 2023, 12:23 AM

#

as long as the version is not the same as the one you are updating to, it should be fine

hardy gyro May 25, 2023, 12:43 AM

#

I tried deleting everything from all three micro SD cards and reinstalling the Bandai update first, and the patch update after the Bandai update wouldn’t work. The three SD cards still give the error code. Should I try a factory reset?

carmine warren May 25, 2023, 12:45 AM

#

I don't think that'll make a difference because the upgrade logic happens before save data is loaded

#

Did you make sure to push the card all the way in? Do your Dims/BEMs work correctly?

hardy gyro May 25, 2023, 12:48 AM

#

Yes, the SD card was put all the way in. I can use other DIMs to hatch new eggs.

#

I did factory reset it (after transferring my Digimon to the app), and I tried both the 32gig and 4gig Kingston SD cards. They did not work. Each time I tried, it showed Error, E02.

#

I’m just trying the Bandai update first, I’m not too worried about mods at the moment.

carmine warren May 25, 2023, 1:15 AM

#

That's just really weird. If what you used worked on one but not another, I think it's just defective. Maybe you can take it apart and see if something's shorting out, but I think it would be a better idea to get an exchange

#

The alternative is they changed the keys, but that doesn't really make any sense

carmine warren May 25, 2023, 1:46 AM

#

Where'd you buy it from?

hardy gyro May 25, 2023, 3:01 AM

#

I purchased it from Zenintcg.com

carmine warren May 25, 2023, 3:07 AM

#

Hmm. Well message them and see if they can do an exchange. I don't know how they handle defective merchandise. Last time someone mentioned it wasn't frictionless

hardy gyro May 25, 2023, 3:12 AM

#

I’ll reach out tomorrow and ask. Thank you guys so much for trying to help!

carmine warren May 25, 2023, 3:19 AM

#

If Zenin doesn't give you a satisfactory resolution, and you're somewhere in North America, you can send it to me and I can take a look. Malfunctioning VB stuff is fascinating to me

abstract dove Jun 11, 2023, 4:57 PM

#

Hello @hardy gyro ! Are u using the special selection BE? The black and gold one, cause i'm having the same issue. Tried it both with Sandisk Ultra and Kingston CANVAS Go! Plus 64 GB, have formatted them to FAT32, but both gives me the error without the waiting. Checked version on the BE and its 1.0B

Followed the guide as well and could not resolve. Did you manage to resolve the issue?

#

hardy gyro Jun 12, 2023, 10:01 PM

#

Hey, @abstract dove I was not able to resolve the issue. I wonder if more people are having this problem with the black and gold version.

abstract dove Jun 12, 2023, 11:38 PM

#

hardy gyro Hey, <@183271424918552577> I was not able to resolve the issue. I wonder if more...

Thanks for the reply! I was going insane.. @carmine warren sorry do you have a solution for us?

I'm still waiting for @hardy gyro's device to arrive for analysis. Will know more when I get it

#

Appreciate it!

carmine warren Jun 13, 2023, 9:13 PM

#

I broke out the logic analyzer

#

Here's what an idle response to ACMD41 looks like. Look at the tight grouping of clock cycles near the end. When the card is ready to respond, it sends a 0 bit and 7 additional bits for an R1 type response. This response has the least significant bit unset to indicate it's still initializing.

#

Here's what it looks like on the problem device. As you can see, the bits are bouncing a bit during that response. Note that this is with the same card, so the card shouldn't be the problem.

#

Ah shoot, these are actually for success ACMD41. So flip what I said, at this point when the R1 LSB is unset, it's finished initializing

#

Before initialization finished, you would see 0xFF 0x03 there

#

Anyway, the problem is because that signal is so noisy for some reason, the system can't ascertain what the response actually is

carmine warren Jun 13, 2023, 10:35 PM

#

Well. Looks like the VB is grossly undervolting the card. How did that happen?

hardy gyro Jun 13, 2023, 11:11 PM

#

Well, I’m glad I wasn’t going crazy. 😹 That’s weird that it would do that. I wonder why it has no issues reading DIMs.

carmine warren Jun 13, 2023, 11:40 PM

#

Because it appears to have two power supplies. The slot is switched on the low side, and compared to the original VB, they moved the slot shell ground from the global ground to the same net as the card's ground, and now there are two resistors connected to the gate of the MOSFET that powers the slot.

#

From the looks of it, one is supposed to provide 3.0V, and the other 3.3V

#

My guess is someone accidentally typed the wrong resistor value while programming the pick and place and ended up dividing one of the supplies by half

carmine warren Jun 14, 2023, 12:31 AM

#

Hmm, the resistor values are pretty close to what's on my VB. So my next guess is potentially dead I/O pin

carmine warren Jun 14, 2023, 12:59 AM

#

Well, I've found out what's wrong. The SD card power enable pin's dead

hardy gyro Jun 14, 2023, 1:03 AM

#

Damn, that sucks. Is it fixable?

#

My husband and I had a feeling it had to be an issue with it reading the SD card since it rejected the SD card so quickly when trying to update. My husband’s plain black VB changes to the waiting screen when updating.

carmine warren Jun 14, 2023, 1:11 AM

#

I think it's workaroundable but may be fiddly

#

The good thing about low side switching is you just need to connect the GND of the card to GND of the board

#

Not permanently, of course, since that would make the slot on all the time

hardy gyro Jun 14, 2023, 1:28 AM

#

If you need to take it apart to see if you can work you are more than welcome to. It does make me wonder if they programmed and built a good handful of the black and gold VB’s the wrong way since radix is having the same issue.

SHINKA!

carmine warren Jun 14, 2023, 1:29 AM

#

I think it may be a lapse of QC. IIRC they don't have a SD card test in the factory test program

#

I'll also dump the bootrom to check if it was a bad internal firmware write or something wrong with the pin itself

carmine warren Jun 14, 2023, 2:29 AM

#

Well. That was easier said than done. I think the odd floating ground is why it never enters update mode when I had the ground line connected to the ground on my logic analyzer. If I try to tie it to real ground, the card's just not getting recognized as plugged in by the bootloader

#

I might need some time to figure out what to do about this

carmine warren Jun 14, 2023, 2:56 AM

#

But, at least I can confirm this is an actual manufacturing hardware issue. Shame Zenin wouldn't do anything about it.

hardy gyro Jun 14, 2023, 2:57 AM

#

You’re good! Take the time you need. Thank you again for taking a look at it. If it was me, I wouldn’t have the tools or probably the patience to get that far and figure out what the exact issue was.

carmine warren Jun 14, 2023, 4:45 AM

#

Ayyy managed to workaround. It is a bit roundabout, but it works

carmine warren Jun 14, 2023, 6:12 AM

#

Dumped the internal ROM, they're identical, so this is definitely something wrong with the chip or the bonding to the circuit board

abstract dove Jun 14, 2023, 6:12 AM

#

Thank you so much for working on it!

#

Kinda shame that I liked this design and was hoping that I could use the time saving mods!

hardy gyro Jun 14, 2023, 11:07 PM

#

Awesome! That’s some good news. It’s a shame for the other internal ROM.

carmine warren Jun 16, 2023, 2:12 AM

#

abstract dove Jun 16, 2023, 6:09 PM

#

ineedthis any guides so that we will be able to do the mods on our end?

Slinky Ramune (@GMMan_BZFlag)

So here's the workaround: connect slot ground to system ground, then pull the pin used for SD card detect, pin 8, up. While my setup looks complicated, the logic analyzer is really only there to provide a pin to connect to ground.

#

This is specifically in the case of bad voltage. It's useful if you have a breakout to check the voltages, but if you don't, you can disassemble to check

#

Slinky Ramune (@GMMan_BZFlag)

On the circuit board is this arrangement. The power to the microSD card slot is low side switched with a MOSFET. It is turned off by default using the pulldown resistor R36, and turned on through something on the other side of R24.

#

Check R24 on the side closer to the battery wire. It should show 3.3V when the SD card slot is active

abstract dove Jun 18, 2023, 11:13 AM

#

oof that looks out of my skill set

#

i'll see if i can make it work

magic lotus Jun 20, 2023, 11:12 PM

#

Is this a general defect on the special selection? Or was it on some specific devices?

carmine warren Jun 20, 2023, 11:31 PM

#

It's probably certain devices, but don't know rate of occurrence

magic lotus Jun 21, 2023, 1:07 AM

Yup Ive just tried it. Waiting screen did not appear and just got E02 error. Im using the black and gold VBBE.

has anyone else tried this method i really dont want to buy a different VBBE

uhm ignore me i did it

how did u do it?

didnt want to buy a new VBBE as well

little ether Oct 28, 2023, 9:16 PM

#

@abstract dove I used a different SD card. Talking to others, it seems like it's just a process of elimination on what sd card your vbbe accepts

abstract dove Oct 29, 2023, 2:21 AM

#

May I know what brand you used? @little ether

abstract dove Oct 29, 2023, 2:42 AM

#

Would like to purchase the same one

little ether Oct 30, 2023, 9:20 PM

#

@abstract dove I used a SanDisk Ultra 128GB with a SanDisk MicroSD Adapter.
(Not sure if the adapter came with the SD card, these are just randoms I had lying around the house)

The sd card itself wouldn't format to fat32 through my laptop, so I found some program my roomate reccomended to reformat it, and it somehow worked.

This was my second attempt after having failed with a NexTech 32GB/Kingston Adapter.
