[SOLVED] Help to identify firmware for MK809IV TV stick with RTL8723bs WiFi

[goolpone]

Hi,
a week ago I bought the following MK809IV TV stick and I bricked it without making a backup.
I need your help to find the right firmware for it.
External packaging is labeled MK809IV with a red slider.

Board version: H122V1.4 0422 without a NAND chip.
Label on the back: RK29_809_V1.0 221 # - HXB_19060601
Processor: RK3229
Board: rk30board
GPU: Mali 400 MP
RAM: 2Gb
ROM: 8Gb
WiFi: RTL8723bs

Original firmware was based on:
Version: Android 7.1.2
Build: hx322x_box-userdebug...
kernel version: 3.10.104

I tried to flash dozens of firmware, and the only one that actually works is:
rk3229_7.1_box_MX4VB_SSV6051p_SpecTek_flash-update_20171209
but it shows only 1Gb of RAM and does not have the WiFi.

Any help is appreciated!
Thanks and regards.

Ok guys, finally I found a working solution for this TV Stick.

Let me share my solution:
Basically, as mentioned in the first post, I found a working firmware with no wifi and just 1Gb of ram: rk3229_7.1_box_MX4VB_SSV6051p_SpecTek_flash-update_20171209
So I continued to search for a different firmware and I found this one:
G809_3229_L_2G_8723_20180517_1451_2018070601

Unfortunately also this last one is not able to boot, but what I though is why don't try to flash this last firmware anyway and using the bootloader from the previous one?!!

So I have extracted the Loader, uboot and trust images from the first one (rk3229_7.1_box_MX4VB_SSV6051p_SpecTek_flash-update_20171209) and flashed over the already flashed second one (G809_3229_L_2G_8723_20180517_1451_2018070601) using RK_Android_Tool v.2.3.9.

Steps are:
1. Flash G809_3229_L_2G_8723_20180517_1451_2018070601 image using BatchTool and selecting "Restore".
2. Make a short with a paper clip to the pins 6-7 and plut the USB in the OTG port
3. Load the Working images: Loader, uboot, trust and parameter files to RK_Android_Tool v.2.3.9
4. Start the flashing

First boot required about 10 minutes.

The archive includes all the needed software for flashing, the firmware and the extracted working images for the bootloader.

Hope it can help others!
Enjoy!

I have a stick like yours MK809IV just bought and after doing root, I tried to restore it from the factory and it turns out that it starts up, it connects to the network, the buttons appear on the screen below, but the screen stays black the applications do not appear , Do you think I could fix it with flashing G809_3229_L_2G_8723_20180517_1451_2018070601
since the stick starts up?
I repeat that the stick starts but does not load the applications, I have contacted the seller and I have asked him to send me the firmware he brings from the factory which is:
hx322x_box-userdebug 7.1.2 NHG47K eng.ren 20180822.112718 test-keys
I will wait a few days and if not I will prove your solution, what do you think?

If you can explain to me how to connect the stick to the computer and what to put in order to recognize it

Your solution worked for my device too, I have a MK809V_4k, I tried to flash a better firmware than the installed Andriod Lollipop 5.1 and bricked it, tried many firmwares and none of them worked. I have 1g and 8g, your firmware is showing 2g in memory, but is working OK so far. If we do not install the working images then the device overheats and freezes, by installing the working images the device does not heats and freeze and stays cool. It is very hard to find a working firmware with this configuration with RTL8723bs Wi-Fi chip which supports bluetooth too. There is no firmware available on the internet for this device. So my suggestion is do not try to find a better firmware for this device and do not mess with the already installed factory firmware, otherwise you will be in a lot of trouble. I also installed https://chinagadgetsreviews.com/down...88-tv-box.html, but the Wi-Fi and bluetooth were not working, I guess missing drivers. rk3229_7.1_box_MX4VB_SSV6051p_SpecTek_flash-update_20171209.img is working fine but cannot enable Wi-Fi, and bluetooth is not present. I guess stick with Andriod 5.1
My device says G809 V1.32 and HXW18122702 with RTL8723bs Wi-Fi chip.
