[General Discussion] QF001 (ROCO K706) Head Units with UIS 7862s (not FYT based) [read first post first]

[carmenred_141]

does this forum include the EKIY unit that is sold trying to figure out which model is which KK5,T7 T900 or are they all the same just sold by different vendors, they all have the same 7862(a or s) chipset but have different ICs 7388 7838 and 7850?
Are they all the same?

I don't know if this has already been addressed here, but on my Hizpo S5 4/64, TXZ regularly stops working for me every time I start android and then connect to wifi. The seller sent me the new firmware from 3/2023, but the message still appears. Don't know what to do with it? Thank youView attachment 5871269

This issue was not reported yet. Can you translate what the popup message is saying in English?

As for the firmware file link, if you could share them in the firmware thread that would be cool. https://forum.xda-developers.com/t/...s-with-uis-7862a-7862s-not-fyt-based.4541261/

You......I assume me...

My point is from my experience after using this device for 3 months now, there is no need at all to do anything about the cooling of the CPU...my S8 has not high temperatures or spikes ,..and a copper plate after you mentioned it first I thought yes a good idea, but after reading @marioti tests and some thinking it is clear for me that after all it will not be my choice.
It creates more contact surfaces to transport the heat threw.

But it is a free world, everbody can make choices he want .

I already wrote about 5 times that I don’t see the need to redo something until your radio freezes. But I will correct you. Thermal paste MX-4 has a thermal conductivity of 8.5 W / mK, not 4. And the most important point is that the thermal paste is smeared with a microlayer and has crazy thermal conductivity, and the thermal pad is 1.5 mm thick, and you need to multiply the heat loss by the thickness. With such a thickness, this is an extreme option. Thermal pads are placed on chips in laptops only because it is possible to destroy the chip with a plate. There is a thermal interface, here it is with a thermal conductivity of 12.5 for a thickness of 0.2 mm and a composition like thick thermal paste. But no one has surpassed the thermal paste yet. And the copper plate is only worth it to transfer heat to the body, and not dissipate. To dissipate it must be open. I will say one thing, the thermal pad will save you just because you don’t load the radio tape recorder, if so then you don’t need it either, there won’t be much difference. And the tests are all nonsense, conduct them at least in AIDE64, just turn on the processor test and you will understand what it is capable of and the extreme temperature before throttling. Understand that a copper plate is placed specifically on video cards in mining, since there is nothing more than transferring such an amount of energy, it cannot be bad. You simply do not correctly draw conclusions on temperatures, comparing different processors, that and I threw off a photo of the operation of the radio without a load of 55 degrees before the alteration, 28-38 could only be when turned on. And you argue. Okay, as I understand it is better to close this topic, but I wrote a lot))

I tried to deciphire it. I see "TXZOverseasOTA" but in general online (Over The Air) upgrading doesn't work. And I guess that is what TXZ (system) service is trying to do as soon as you connect to wifi...
Maybe check factory settings to see if you can disable this OTA update setting. Also check with Toppal AI settings, as it depends on TXZ service...

I will be the first to do a stress test on purpose and add a photo to this post. Then do you, as I understand it, only this can close the topic.
And if you like to argue, I suggest you let's write down the stress test of the radio and compare it, and see at what temperature it will go into throttling for you and me. The same with Marioti, I'm sure it will last longer than yours. Absolutely vseravno at what temperature it works, the main thing is only throttling.

Tried to explain the higher temperature of @marioti, think it is a plausible explonation, if you disagree, fine, no problem, if I'm wrong also fine.

Cheers mate

You could try to disable or uninstall that app with this tool https://adbappcontrol.com/en/

As far as I know TXZ is a system app & service. It's its speech service that prevents GA voice activation from working a.o.

unfortunately there is no such setting

Try to disable headlight detection. On some devices it helps

 

[And-S]

When connecting any usb keyboard, something strange happens: one press of a key gives 2 characters. Always. Exactly 2. Any keyboard (tested 5 keyboards, 2 wired and 3 wireless).
Is this the case for everyone, or am I the only one lucky?
Is there anything we can do about it?

 

[Astralech]

There is logic. Now the processor and case have a common temperature, the case heats up from the power amplifier, it gets extra +10.

This is exactly the case with the temperature of the enclosure, it is heated by the amplifier.
I made such a modernization and it's good, and the fan is needed for this added radiator.

I did exactly the same. Barely grinded the inner plate, it's hard)

thank you but it doesn't work

Does LOUDNESS work for you with the firmware from 6/3/2023? The switch works but nothing happens. (S5 Hizpo)

Just checked, doesn't seem to do much but it never did actually

@Barykelo
I've just checked the active services and TXZOverseasOTA is now also listed as a sperate service. Probably added by some firmware update along the road. Did not see it last time I checked. Service can only be stopped but maybe it is an hidden app that can be removed with the ADB tool recently shared. No idea on its role/function though...

While checking HU wasn't connected to internet BTW so it just starts with the system I guess.

PS: I know, my car & dash needs cleaning 🫣

in my original firmware from 9.1.2023 it was a very significant change

I wrote to the seller, so hopefully they will solve it

I personally still plan on doing it that way (always on) but my Sunon fan wasn't delivered with my last electronics components order. It is in backorder. Once it arrives I only plan additionally the front mic mod.

I think you are correct that the copper plate keeps heat trapped in stead of it being dissipated.

When put the Sunon fan, don't put that metal plate back that protects the stock fan...it makes a lot of additional sound when fitted that plate back.. @blue_one already mentioned that many threads ago.
