Is it worth updating? Is there anything special?

 

[corv45]

Cela vaut-il la peine d'être mis à jour ? Y a-t-il quelque chose de spécial ?

A toi de voir si il faut maitre a jour.

 

[sotos_2002]

A toi de voir si il faut maitre a jour.

I mean are there any new features or just bug fixes?

And last question. Can I update only the mcu and not the other one?

 

[corv45]

Hello

please help, maybe someone will have an idea.


I have a radio:

AC8257 – 8Core – ROM 64GB – LPDDR4 – 4GB – 1024x600

Android 10

I tried to install system updates from the post

You can find this wonderfull new firmware here (dated : 20220513), along with the MCU update : https://www.dropbox.com/sh/k2dotip66u7iekg/AAA69Z_ujnTZQMai5TbPXAbma?dl=0

mcu_202206071001BD2-1559.upd

and unfortunately it was not possible to detect this update from USB (made according to the video, unfortunately, in my options it is not possible to select the update, it only looks for it after selecting the update option and resetting the device)


I changed the UMC to the one that came with this firmware:


mcu_202206071001BD2-1559.upd


Unfortunately, after this operation, my FM RADIO stopped working, I tried to change the options, unfortunately, nothing helped until changing the MCU to another mcu_202211111001BD2-1157.upd. After this operation, the FM radio started working properly.


I found another update on another forum:

Link to the forum

>>> Link to the forum <<<

Firmware 8257 4+64 WIFI na 2021.08.05 ATCUPG


This software was installed without any problems via USB, only that it is still Android 10.


My question is, does anyone have an idea why this software was installed without any problems via USB and the others and this thread does not start at all on my radio?




He would still ask for advice because according to the seller, it supports the internet with 3g / 4g donge, unfortunately, after installing the USB dongle, it activates and there is no internet, is it necessary to set some options?

My donge is HUAWEI E3372 LTE USB Stick

I want to update my Junsun v1 pro Ac8257. Who knows to help me?

Unzip both files and put them on an USB stick. Use an old one with small capacity (<32 GB). If the head unit is up and running the new fw should get detected automatically.

Don't miss to try AppSwitcher after your update.

thanks. Have you tested this new firmware? What's new does it introduce?

I installed it on my system, it's identical to the @vz_commo uploaded, except 3 things i noticed

1. It has a newer version of the MCU (never been really sure what this does exactly)
2. The wireless android auto and carplay sometimes doesn't connect because of bluetooth not connecting. It works 8/10 times
3. There's no option to change the boot logo, not sure why
