Looking for bricked, screen smashed or dead battery KANN, payment Via PayPal, preferred shipment method DHL.

I want to help you @Setmagic I had a couple of devices which we can play and I want to help with the OS development.

Hi there! I'm looking for a dead Kann or screen smashed. If anyone had one, maybe could make some bussines. Happy holidays.

I think I missed something to let you think that, let me rewind up again: The device is a DSD with single AK4497 (second hand), the device simply didn't recognize the analogue board, I did try 0.4M,L, K, and I firmware on digital board which is marked as Z1_9325_3. But when I put the 0.4K (Dual...

@maxxkur I did try it without success

Hello again mates, recently I got a DSD with single ak4497, but I can't play any files version 0.5; voltages over DAC are OK (3.3,1.8,5V). However, if I plug the GAD Dual AK4497 digital board works fine. So the question is anyone known which version should I use to get work single AK4497? I did...

Hello @buzzbuzz you should send a Pm to huo guang Store, he states that is very close to zishan developers, and he could get you the replacements that you need.

Hello @Rafinnnnnn15 I want to tell you about the Zishan devices are meant for DIY and optimizations by your self, currently I didn't own the Z4, but I own the DSD's (AK4499 and Dual 4497 by GAD) and they sound amazing but as I did tell you are meant for modding. If you own an M11 will have a...

There's no IC that decode the buttons, it's the GPIO of the FC microprocessor, check any short on the modded phases (such as amps , power IC, etc.) also check the firmware versions, finally check cold joints on the microprocessor and the buttons. If they are like the digital board on DSDs they...

Its me or your device had a solder joint? on the opamp opa16xx near the relay in the capacitor and resistance

AKM4499?

I got some spare parts. Let me check if any works and I send you a PM, meanwhile you could check (when you get the device) which model of LCD is.

@abheybir are you sure that is the lcd cracked or the digital board is in short?

I had the ak4499 you can see marked in red 5v orange 9v white DAC, blue lpf stage, purple buffer green opamo

You can find here more info about it

Stupid question: The clicking, it's not fault of any cap? Maybe in the LDO for 7V (if you hadn't modded) or in the opamp device its self? Also, if current draw rises depending on the file, maybe CPU current is dropped .... causing malfunction of decode those files. In my case, I did not notice...

After the mods done by me I had a problem with my DSD's if I plug it to my MacBook (2012mid-linux-connected to AC) if I power all at the same time, the DSD turns off and only stays as usb DAC and don't shows connected, if I play some files as music player and then I plug it to the MacBook it...

I think if you had heat resistant tape, a good flux and a good heat gun will be no problem to damage the PCB I think also I forgot to mention check the diodes near the ldo and capacitor bank

Did you check the Lipo Charger IC? On DSD's the TPC8107 and the TC4056A delivers the charge CC,CV for the battery and power at 4.3V ish, also check the diodes at the right of the amanero SAM32

I think they don't like to be I don't know how to say it (corrected) since they are doing stuff than others can't do free or by lowered cost, I was trying some things but work it's absorbing me....

Hi, anyone could help me, after try to update my device with the update manager, I always got the error: fot5s.0.0.0.0. ... no connection. Any Ideas?

Hi there, I took some days off, From my point of view Zishan need to do this, as you mention @Setmagic the problem is the CPLD/FPGA delivery from the OS (ZishanRTOS/Rockbox). Maybe can be emulated (or sort of) the USB or the BT since both are I2S and the decode part are from the CPLD to DAC

Same Issue here but with the U1, in Linux without ASIO driver, and also it powers off if you did not play anything in 1 minute. Saving to buy a Z4 and give it a try, maybe as a test anyone could flash the T1 Rockbox to see if OS works or tell Zishan to do a port of it for Z4.

Here Hiby R5, ZiShan DSD's and U1, as we have discussed the ZiShan devices are for modding, totally different as the mainstream, I think my DSD's sounds better than R5 in SE using Sen HD660s and Onkyo HF300. But I think is due to the limitation of Voltage used in R5 (+-5V) against (+-9V) of DSD's.
