Yoton YM03 problem, second video
I ordered the YOTON MP3 Player YM03 from Amazon Germany on February 5, 2024, which was delivered a few days later.
I am very impressed by the features of this player: small, light, easy to pair, plays my MP3 files without any problems. I was happy to have it in my hands and to be able to play my audio books with it.
BUT there is a serious software problem which has rendered the device inoperable after only 2 hours of use.
The problem cannot be solved by a RESET. I am currently waiting until the battery is completely empty in the hope that the device can be restored to a functional state when it is recharged. If this also fails, I will return the device.
I will describe the steps here on how to reproduce the error (firmware version: YOTON-YM03 V3.2.0.8-J):
1. charge the device to 100% battery
2. upload MP3 files
3. connect Bluetooth 5.0 headphones
4. play playlist
5. press the pause button
6. wait until the device goes into sleep mode
7. wait another 5 minutes
8. press the play button
Expected result: The device plays the current MP3 track
Actual result: The device displays the folder icon of the menu, but can no longer be operated using the buttons.
After 20 seconds the screensaver screen is displayed (date/time display), after a further 30 seconds the device goes into sleep mode again.
The device can be woken up using the play button, but then remains "stuck" in the folder icon of the menu.
After switching the device OFF and ON, nothing changes in its behavior - it remains inoperable.
After a RESET, nothing changes in the behavior - it remains inoperable.
Here the whole conversation with support.mp.eu@yoton.co:

Hello Manfred
Thank you for contacting me and I will do my best to solve the problem for you.
Could you send me a short video showing the problem you encountered?
And I would be happy to send you a firmware to solve the problem.
Unzip the file and copy the hexadecimal file directly to the SD card, then look for the update function in the settings.
After successful update, the firmware version will be V3.2.0.6.J.
Hope it works for you.

Hello Emma,
thanks for your feedback.
I have downloaded the new firmware and copied it to the device. But I can't run the upgrade function on the device because the device is blocked. After switching on, but also after a RESET, the device is always in the same menu, which cannot be navigated with the buttons. So I am not able to do anything on the device.
I have uploaded a short video of the behavior on CZcams. Here you can see exactly what I mean when I say that the device is not operable.
Is there anything else I can do?

Hello Manfred
Thank you for your reply.
I will ask our engineer to see whether he has other better solution.
We have another update way, which requires the computer and an software. That may be too trouble for you.
So I would like to replace it for you first. OK?
Would you please send us the following information for shipping ?
Waiting for your message.

Hello Emma,
thanks again.
You are welcome to send me the alternative update option. I am a test engineer and should be able to cope with it ;)

Hello Emma,

Thank you very much for everything,
Manfred

Hello Emma,
great news: The package arrived yesterday at noon - I love Amazon Prime shipping ;)
The MP3 player works as expected straight away. I already sent my Amazon review yesterday - and of course the positive retailer rating for Premium Support.
It has the same firmware installed as my first model (YOTON-YM03 V3.2.0.8-J). I haven't connected my Bluetooth headphones yet because I'm afraid of getting the same error condition.
What do your developers advise? Should I downgrade to the firmware version V3.2.0.6.J supplied by you?
Manfred
[23.02.2024]
Hello Manfred
Glad to hear that.
No need to degrade it.
Please have a test first. If any problem with it, contact me freely and I will try my best to solve it for you.
Wish you a nice weekend.

Hi... did you persist with the problem one and see if discharging the battery allowed it to then charge to a functional state? I currently have the exact same error on mine, and am currently stuck with it. Haven't had a response from their customer service yet. Unfortunately, the battery will likely take a very long time to discharge (it goes into standby mode after a couple of seconds, so power use is minimal).
Hello BeardyGeoffles, Unfortunately, I have not yet been able to test this myself. As you have already realized, the battery loses virtually no power. My defective device can still be switched on, only to switch off again shortly afterwards. Nevertheless, I don't think it will be too long before it can no longer be switched on at all. Then I'll see if a reboot can fix the problem.
@@manfredbecker7807 I’ve actually had a response from them now and they are sending a replacement and a firmware update tool to (hopefully) prevent the issue arising again (will also try this tool on my stuck device to see if I can get any progress on that)
@@BeardyGeoffles
@@BeardyGeoffles Nice to hear. If the upgrade with the tool works, I absolutely have to have it ;) Please keep me up to date.
@@manfredbecker7807 It hasn't worked... I've just tried it now. Fortunately, it doesn't brick the device. It recognises it when I plug it in, and starts the flash process, but gets about 11 secs in and fails. The main downside is now that the device is charged back up to full and I have to start the battery drain again. When you got your replacement, did you update the firmware on that one, or are you still using it out of the box?
Hallo Manfred, ich bin an dem Firmware-Update interessiert. Kannst du die Version YOTON-YM03 V3.2.0.8-J irgendwie zur Verfügung stellen?
Hallo Torsten, ich habe leider nur die ältere Version v3.2.0.6.J vom Support bekommen. Du kannst dich aber an den Support von Yoton wenden. In Amazon auf den Artikel gehen und dann den Hersteller Support kontaktieren. Viel Erfolg, Manfred

hey, wie man die CASIO FX-850P-Fraktionen und Grad berechnen
+braulio meza Hi, a+b/c können mit dem Casio Pocket Computer nicht dargestellt werden. Die Umrechnung einer Dezimalzahl in Grad, Winkelminuten und Winkelsekunden geht mit der DMS$() Funktion. Z-B- DMS$(1.23) = 1*13'48. Umgekehrt geht das mit der DEG() Funktion. Z.B. DEG(1,13,48) = 1.23
+Manfred Becker meine Frage ist, dass Taste gezogen werden kann ist, dass Fraktionen und weiß noch nicht, Aye Grad ist das "s" DMS $ (nur wollen, um Yea Schlüsselbeutel kann Fraktionen oder Fraktionen zu tun wissen,
i have no memory RP-8 but i need ?
Hi Raja Amjad Hussain, I have also no RP-8! Please try on eBay: www.ebay.de/itm/Casio-RP-8-8K-BYTE-RAM-MEMORY-PACK-/221722702679?pt=LH_DefaultDomain_3&hash=item339fb3f357
i need fx 880p memory pack plz help me my cell number 00971562159237
Hi Raja Amjad Hussain, sorry, but I do not own a RP-8 or RP-33 RAM modul. The Casio FX-850P comes with a standard RAM of 8 Kbytes, the FX-880P with 32k bytes. For larger programs, or for handling large amounts of data RAM expansion kits are available optionally. By adding the RAM rate RP-8, the storage capacity is 16 Kbytes (FX-850P) or 40 Kbytes (FX-880P) expanded. With the RAM set RP-33, the storage capacity is 40 Kbytes (FX-850P) or 64 Kbytes (FX-880P) expanded. But if you can handle a soldering iron, and is familiar with SMD technology, there are other ways to expand the memory. For example, you can replace the built-in 8 Kbyte RAM module by a 32 Kbyte RAM module in the FX-850P. As a result, you will then have a bona fide FX-880P. A detailed description can be found here: Memory Expansion I . manib.bplaced.net/blog/?page_id=205 If 32 kbytes are not enough, you can additionally install another 8 or 32 Kbytes of RAM. Thus, even without a RAM kit RP-8 or RP-33 on an internal memory of 40 Kbytes or 64 Kbytes !. A detailed description can be found here: Memory Expansion II . manib.bplaced.net/blog/?page_id=207
