Blackcat - sitting here cracking up reading your tag lines...

You would be surprised how few posts include that sort of basic information.

I think this is what you're looking for:

Office 365 needs TLS V1.2
On "old" Saturn Range we have support for TLS V1.0 only.
V1.2 not implemented up to yet and no more upgrade to V1.2 planned from Kyocera side.
Too old system, sorry...
There is no official document about all fixes or else available.
(I have seen 1 file, but in japanese language only...)
I think they they won`t share

Got it working. Long ago I had written a software routine to "wrap" TLS 1.0 inside of a TLS 1.2 packet. I just needed to get the 250ci up to TLS anything. I got a hold of the firmware yesterday to upgrade it to 2016 and everything is working fine with Office 365 now. Thank you everyone!

Hello,

I hope someone can advise me but i have a serious issue with my TA 300Ci.
I tried yesterday to update my (good working) TA300Ci with the latest FW V16.24.0010 (2016-08-18).
The original FW was the V13.006.2012.01.06.

I unpacked all my files from the zip to the root of my formatted usb 4GB flash drive (FAT32).
When i started the machine i got stuck in the welcome screen.
The screen won't disappear anymore even without the flash drive.

I've tried to;
1. flash only the FW of the CPU OP.
(changed the dipswitch on the OP pcb to 'boot')
I waited until the led stopped to restart the machine.
Then i changed the dipswitch again to 'normal' en tried to flash again without succes.
2. Unpllug the Code dimm memory and restart the machine without succes.

Are there any other things you can suggest me?

Any help is welcome!

at Saturn range it was sometimes a little bit "tricky" to upgrade.
If system stucks in "welcome", you has to use usb key with "read/ write" led/ <4GB./ FW included "ES_SKIP.ON"
At first you has to check if led is flashing.
If yet, you has to wait up to 25-30 minutes for changing from black FW upgrade screen.(Panel upgrade starts...)
If not, boot rom on flash dimm would destroyed and now it will be difficult to explain further procedure
(I swapped the flash dimm (upper slot) during upgrade procedure in past...)
You has to use well working flash dimm from other 250ci/ 300ci to get boot routine.
System will show black "FW Upgrade" screen after startup for approx 20 secondes before screen will change to "writing main FW"
This will be your time frame to swap the well working flash dimm against the broken one.
If you are too slow, you will destroy the well working one also...
If you are fast enough, FW upgrade will repair the broken one and system will work again!

Hello KYO_OEM,

Thank you for the advice.
It's difficult to find spare parts for this model.
I found a 2nd hand machine for 20€ on a website with a broken transfer belt but i have to take the complete machine!
Someone you know has a working code dimm slot for sale?

Hello,

I've took the code dimm out of the machine and got this;

it`s clear for me.
System is loading the FW from USB key to memory and after download from key was completed, it tried to write to non existing code dimm.
No target available ---> error message must coming up.

Did you wait up to 30 minutes with mounted code dimm?
Did your key led is flashing during "Welcome" message?

Did you wait up to 30 minutes with mounted code dimm? YES
Did your key led is flashing during "Welcome" message? NO (read/write led) USB Stick is Kingston 4GB
I'll order new code dimm on ebay. I saw one for 8.5€
Shipping will take approx 2 weeks (COVID).

I'll follow your advise to install the new code dimm and install it with the broken one.
I'll reply to this thread as soon as the installation has been done.
Thx!
