Hello sir, actually you were right and I got worst then your case, i didn't found any isolation there, so I did like you and the blinking buttons stopped but I think I wasn't lucky because after assembly I got a black screen without anything showed, except when I connect the usb to the pc i got maskrom mode but I cant pass the flash.
I think I maked the situation worst when I tryed to flash with this iasue.
What do you think I can do now and thanks a lot anyway the results, you do a great work sir.
Seems like you did not read the instructions and flashed 1024*600 screen resolution instead of 1280*720. At least black screen says so. Put the correct oem.img and re-flash the unit again. Actually it can be done using usb stick, but your device is disassembled and it is faster to shot a resistor one more time. If you have some specific error in MASKROM mode, please show it to me.

Hi friend,
Returned to the first error message in RKDevtool ( Prepare IDB fail), I did download the right Oem file for 720p screen, and I am using the usb cable used to flash the 1st time, but still have this message even if the MASKROM mode appears in the bottom in the flash tool in PC.

I'm sorry but I don't know what to do :( I can't adjust the volume of the calls, the ringtone sounds very loud. If during the call I raise the volume to listen to the call then if they call me again the ringtone is very loud. problem must be in all klyde. no one has a solution? I don't even see it in the list of common problems. I don't know how to fix it.
I would need to be able to adjust the ringtone volume and call volume separately

The only known reason known for me there is in the resistor discussed earlier. Do you have a multimeter? Can you measure its resistance? Can you desolder it completely and try without it? Then it could be soldered back if its resistance is OK and ~21Ohm.

This is not official support page, Klyde do not pay me for that and this thread exists because I created and support it just for fun.

You are the second who complains. There were some suggestions. If they do not work, maybe someone will add some idea later.

Ok, I understand. Thank you. if anyone knows something please let me know. I use the erisin rom. Does anyone know if with the official klyde rom it is possible to adjust the volume of the ringtone separately?

Thanks for your efforts from my side, I am still trying to recover my unit and you help me a lot sir, now I passed the flash with the right oem file but i still get a black screen? Can I pass another android version like 9 or some other idea plz?
Thanks in advance.

now I passed the flash
That is great news. What did you do to achieve that?
but i still get a black screen
hmm... how about the cables that go from motherboard to TFT board and from TFT board to screen? If you are sure that OEM file is correct and your screen resolution is 1280*720 then it is needed to look into cables.

Was the MASKROM mode disabled after flashing automatically? I.e. PC should not see MASKROM device without shorting the resistor.

Also take a USB stick with work indication. If it starts blinking for a short time when plugged in that means that coreboard and mainboard are OK. If you can connect a speaker and it starts playing/buzzing after pressing the radio button - android is started correctly and the question with screen remains.

Basically I checked the PC and it still see MASKROM without shorting the resistor, and even without give power the the unit, just connect the usb and maskrom appear, this confused me.
And the usb flash led dont respond at all.
Looks like something is damaged with the short circuit wich was made by the 1st problem, now I like to know if nothing work what I can change (hardware side) to can recover at leaset my unit and from where can I bay it ( in Ali express)?
Thanks a lot for your support.

The fact that the unit is visible without power is OK. But the fact that the unit is in a MASKROM after successful flashing says about some damage. I repeat the suggestion to remove resistor. If its removal helps - great. If not, check if both legs of this resistor (after its removal) are shorted to the ground. If so, CPU is damaged. I'll try to give you a contact who can sell a coreboard on AliExpress.

Honestly, I can't do that my self so I will try to find someone have the material and the capacity to do so, but in the same time I would like to get the seller information in Aliexpress so I can see if I can bay the coreboard or not, then I want to know if the coreboard replacement will surely fix the issue and what aboutbthe compatibility with my motherboard ? Can I just bay a px5 with android 9 for example? I DON'T want to spend a lot of money in something i am nit sure it will work as you know.
Anyway I want to thank you million times for you support and for you time as well.

You can send a coreboard to me (Ukraine) and I can try to fix it or confirm that is completely dead, but, I guess, that will be the last thing you want to do :) and it is really better and faster to find someone locally.

She ignores :) me as I never purchased the things directly from Klyde, but if you write her with the request to buy something, she will do that with a pleasure.
what aboutbthe compatibility with my motherboard ?
Any PX4, PX5 or PX6 coreboard designed for MCU CSN2 with DSP (you have DSP, according to the history) will be working.
Can I just bay a px5 with android 9 for example?
Most probably there will be android 10. But yes, you can.

Anyway I want to thank you million times for you support and for you time as well.
P.s. Donation details are available via the link in the heading post, but that is not mandatory. I'm helping just for fun :) and happy about that.

Thanks a lot man, I will try to contact them to get a new coreboard if the price will be ok, and be sure I will returne back to you when I get something.

Hi, I solved it by going back to the firmware (202011261850) I had the same problem, I have carried out numerous tests. Then I realized that the problem is the latest firmware (202101041604)

OK thank you. I will try these days to install the version (202011261850). In that version, how does the volume of the ringtone work? fits separately? Or what steps should I follow to be able to adjust it? I would also like to know what version of MCU you use, so that I have everything the same as you, so that it works correctly for me. Thank you :)

I have the latest MCU. The car stereo plays the smartphone ringtone. The ringer volume is much lower. Even the latest erisin firmware does not have the problem. I don't like erisin firmware for the radio app. When I go to store a radio frequency it stores the frequency and not the name of the radio.

today I'm going to try it. Regarding the fact that the latest version of erisin works fine, I do not agree. I use Jan 6th 2021 202101061613 with Erisin launcher

and the ring tone does not work well

Dnes jsem poprvé použil handsfree a je to špatné!
Mám DSP a zvuk hovoru je příliš basový - neslyším volajícího. Nastavení hudby je v pořádku, ale při volání musím ekvalizér přepnout na „vyšší tóny“. Chybí mi možnost nastavit zvuk pro telefonování na „základní nastavení bez DSP“. Není v tom trik, apk?

Hi friends,
I have just buy and mount an Head Unit on aliexpress for my Peugeot Rifter 2019.

https://fr.aliexpress.com/item/4001228345564.html?spm=a2g0s.9042311.0.0.2b826c37LfDAtd

This Head Unit seem to be a Klyde and work great.

The only problem is that the front radar only work when I'm in reverse gear.
His someone have a solution for this problem ?
Thanks for your answers.
I'm not sure, but try the factory settings, there was probably something about the front radar.

Please do you work setting the Sound-Balance and Fader in Normal? It only works for me in Advance.
Thank you
