Hi.
I have Coolech 1FA-09D based board with Hisilicon Hi3716C chip on it. It's android based media player. Full system flash was performed on the device, but firmware flashed was wrong, so device is now useless.
It stops at boot screen (not android, but bootloader). On device I have 2 available usb ports, but I asume those are host ports, not to be connected to PC. On PCB I have 4 pin connector, but don't know what kind of connector that is. At the moment I have no documentation for the box.
Company that I got box from will provide me original firmware, but how I'm going to flash it? Any ideas? Fastboot as far as I know works only with usb connected devices. ADB can't connect to device trough lan cause no adb server is running on the other side (box get's its own IP address and does some other initialisation which includes usb ports and then freezes).
The 4 pin connector is a serial console, but be carefull, its 3,3V logic and not RS232! So you need a level converter or usb ttl converter cable like for a old cellphone or something. Then within uboot you could load the firmware from tftp or upload it with xmodem.
Could you please send me the firmware? I would be very interested in it . (Or just upload it somewhere like filesonic)
Thanks.

Thanx for your answer.
About the firmware, sorry, I can not send it to you and there are two reasons for that:
I don't have the firmware yet. When I get it, I'm not allowed to distribute it. You can find kernel source code of similar device (A.C.Ryan android based box) on their web page. Their device is also based on Hi3716c.
Hi,
Yes, I am using a acryan box clone and wanted to check out the features of the Coolech firmware on my box. That was the reason I asked about it. But okay, if you can't share it, its fine.
Hi,
Not sure if others have had this issue yet, but its been driving me nuts for three days now.
Basically, I done a fresh flash to latest JB 4.3.1. now I having issues with transfering files via wifi or USB.
Its like its not mounting correctly or updating folders correctly.
If I try and transfer via usb, it will transfer one or two files then give error saying device is not present or some other stupid error.
If I try the same via wifi, it gives IO errors.
If I do anything on the tablet itself, it works fine. I can download games and stuff from store and it all works perfect.
This is why I didn't notice it until I spent 6 hours resetting it up and came to installing my emulator files.
I have tried different drivers, but nothing helps. This happens on complete stock or custom kernel.
Never had these issues with 4.2.2.
The current version is 4.3. The latest small update of about 2Mb keeps the version also at 4.3, but the Build number changes to JWR66Y. I had previously updated to 4.3 and recently took the small update to JWR66Y and my usb connection still works fine. If I use the original usb cable and use a rear usb port on my desktop, I have no problems with transferring files. Using a 3rd party cable or front usb port can result in the kinds of errors you're getting. I don't know why the wifi transfers are not working though.

Yep, JWR66Y is the version.
Been using the same ports and cables before update all was fine. USB transfer has never been great, but to play up this bad is crazy.
I disconnected usb and rebooted, then used WiFi and it seems to be working ok.
So it has to be something to do with it mounting when USB is connected. If usb is connected and I do WiFi, then I get all types of odd errors.
In recovery, ADB pull works perfect. I can pull and push as much data as I want through USB.
Hello, please help with updating and where to download new software for the above-mentioned radio. Chipset AC8227L, 1/16 GB. I downloaded programming from https://forum.xda-developers.com/t/help-with-this-chinese-hu-alps-8227l_demo.3930394/ ; every time ith throws an error to let me check the usb and files. I changed 3x USB stick and memory cards, each time the same, FAT32 format.
Hi, format SD card possibly greater than 4GB with standard settings - FAT32 or ExFAT file system and deafult allocation rate.
Next, download one of firmwares that suits your device (for 8227L it has a lot of them on this forum but your device maybe have different UI than XPH.8227_8_xxxxxx mentioned in this above link).
In my oppinion the ones that will work for your model begins with XRC,CHS, JC.
Firmware for download are like this example : CHS.8227L-8.UI4.Android_10_ver.6_xxxx(date of update)
After download and unzipping two files, .bin and .upd transfer those two files on freshly formated disk, nothing else just these two files. If transfering from PC or laptop make sure that you eject the drive before pulling out from PC.
Next step is to make the unit recognize system on SD card. Put the ignition key in contact mode or better turn engine on (before that insert SD card in memory card slot, not MAP slot !) and start tapping with one finger on center on screen untill message DETECTED is seen on upper screen area. If successful it will recognize files and start automatically updating (wait till finishes and enters system / UI), if not or fails to recognize files for update repeat process two or three times untill successful.
If still nothing, enter erase mode / recovery mode (purge of internal memory and files) by tapping with all five fingers on screen. When recovery is completed (it will turn to factory settings) device will be empty of all memory tasks, prevoius configurations etc. , just clean install of Android system, running and with no apps and settings configured. Then insert SD card and try update again.
If device even won't go in recovery mode then you have some factory settings like "protection" or "install" enabled. Turn this off both in factory settings / menu OTHER.
Good luck !
Can I ask for a link where can I download the above software ? unfortunately I cant't find it in google.

It's on forum here just type in search bar 8227L firmware and find best choice for you. If not found wil send you a link.
Sorry but I am not able to find the latest software compatible with my radio, there is too much of it, please help.
I will add that my radio does not have slots for SD cards and Maps, there is only a female USB input to which I can connect a USB flash drive, the device is fully touchable without buttons.
it is probably a Chinese counterfeit I bought on aliexpress, there will be a problem with the selection of the update
Similar firmware to yours is here https://drive.google.com/drive/folders/1a9yoWoiuMZRoQVL5O677Y9tmQHHAtmbo
Try to install this one it is TSKJ/CHS UI firmware for devices with 8227L chipset.
Extzract and put downloaded files onto USB drive formated for FAT 32 and try updateing.
memory formatted in FAT32, tried for two different, only two files extracted, each time in green DETECTED and after a while in red "Fail, please check USB and files", I tried several times
restoring the settings with a five-finger touch also did not work
I deleted the data to the initial state, but the update still does not start
I noticed that if I detach the USB and I make a finger movement during startup, the symptom is the same, as if I would not see the usb
Do you have install option in factory settings disabled ? Or protection option ? If do deactivate PROTECTION and enable INSTALL in factory settings (pin code) / OTHER submenu. Then try updating again.
yes, I have it done, I also entered the pin, unfortunately unchanged
Use another USB drive with 2.0 speed not 3.0 if this is the case.
Maybe it's just some stupid thing like this that is keeping you from updating.
If this not succesfull either check your device usb ports if they are working thru USB debug command in factory settings, also turn on all USB to be 2.0 and not 1.1 maybe will help somehow. I think that USB port is missconfigured and are causing not to update.
Another thing , if you have by hand any SD card and USB card reader try with that.
I have debugging turned on in the settings after entering the code 8888, and the USB is switched to 2.0, I tried with a new pendrive and with an SD card reader that I put into the USB, unfortunately still unchanged, I also changed the USB input on the back of the radio by switching the cable

Hm, this is a hard one, has this unit of yours been rooted ?
Honestly, I don't know how can I check it? how to root?
If it turns out I have root, does that change anything?
Install from Google play any app that contains root tester and see. Yes if it is rooted device is modified and altered and do not have stock firmwares, which leads to undesired complications and problems.
If the device turns out to be root, it is possible to work around it in some way to install other software?
I checked, the app showed that my device does not have root
today I bought memory 2.0, but still unchanged, these are my settings, is everything ok?

Hello, I have a problem with this unit updated to 2020, downloaded this firmware -8259P_ 军 灿 UI02v1280x720- 国外 11_v1_20220323- as I insert the usb the update pop up appears but at the time of restart it gives me an error, tried with usb inserted and asto rst but nothing , tried 6 different usb sticks with the same Fail result. please check usb and files.
The nibs all formatted in fat 32 as by several online videos, I don't know what to do anymore.
Usb attached 4-pole plug.
Thank you all
fixed by first updating MCU and then passing update.
I enclose MCU for those who have the same problem as me.
Hi I don't know if this is the right place for this post, I'm new here.
I have a problem with my Junsun V1 PRO, it does not detect me the USB, in hidden configuration of the radio, in the code 8878, and in the Others section, I do not see the USB, instead there is Ihone-Eth ????
Are there any forum members, who have the same thing happening to them?
Could it be a firmware issue?
As it does not detect me, or not having the USB option, I will not be able to update a future higher version of the firmware.
The USB cables are well connected, I have tried with the two that came with the radio, and also another adapter to use the original USB of the car. With none of them the USB option appears in the hidden menu of the radio.
My car is HYUNDAI TUCSON 2015-2018.
