[Android Head-Units] onedollarinmywallet:
I recently purchased one of those Chinese Android head unit to replace the stock Honda factory stereo (6-disc CD) in my 2008 Honda CR-V. This unit was sold on Amazon and the seller actually included the necessary bracket/frame to replace the original factory stereo. It was marketed as "Android 10 Car Radio for Honda CRV 2007-2011, 9 Inch Touch Screen 2G RAM 32G ROM Stereo Bluetooth WiFi GPS FM Support Mirror Link with Dual USB."

From what I could extract from the various screens, my HU is:

FF-5000 (Alps) as reported by Google

HMI: JC.D.Q.F.3.01.2021.05.21.08.30

MCU: TS907.190518(H)

Build number:

full_8227L_demo-userdebug 10 011019 1571038753 userdebug

Custom build version:

alps-mp-01.mp5

Kernel version

3.18.79 (gcc version 6.3.1 20170404 (Linaro GCC 6.3-2017.05))

The actual installation went fine with a reverse camera (I had "professional help") but I ran into three issues with the operational aspects of the HU.

Issue #1: I had logged into my Google account to access the Play Store, and it required me to enter a 4 digit PIN. This led to the PIN being stuck on the HU even when I had removed my Google Play account and each time the HU reboots or when I start the car, it prompts me to enter the PIN. A search here on XDA yielded some posts about installing a third-party app to remove the PIN settings which were hidden (see https://xdaforums.com/t/remove-lock-screen-from-android-head-unit.3929076/post-85394787) but I couldn't find the aforementioned app and in the end, I was able to resolve the PIN enabled lock screen by doing a full factory reset/recovery. This was done by tapping the screen with FIVE fingers while the HU was booting up and having it to to "ROM recovery mode."

Issue #2: My unit seems to have really bad FM radio reception; it doesn't seem to pull in any stations at all. The seller had me try changing the "IC Type" in the hidden settings but none worked. Did anyone had any issues with the poor radio reception and what did you had to do resolve it? Replace the unit with a new one? Buy an amplifier? The cables to the FM antenna are connected.

Issue #3: Because of the PIN and poor FM radio reception issue, the seller recommended that I update the firmware and he sent me the firmware (only took several attempts). The filename was "8227L_8众越创UI军灿-国外10_v20_20210521.zip" and there were two files in the zip: 8227L-8.bin and 8227L-8.upd. The seller kept saying to copy it to a SD card and install but the head unit has NO SD card slot. There is a USB cable (two, actually) provided and trying multiple SD card readers and adapters and even USB flash drives and formatting them as exFAT, FAT, FAT32 or even NTFS doesn't seem to work. When I plug in the SD card or USB flash drive and tap the screen while it's booting up, the message on the screen says:

detected

Fail, please check usb and files...

So what does this actually mean? Does it imply that it found a USB flash drive/SD card but can't read it? This part is the most frustrating aspect trying to figure out why I can't get the damn firmware updated because it doesn't seem to recognize the USB SD/flash drive connection. Do I even need to update the firmware in the first place, with what I currently have or is mine outdated?

One disadvantage of doing the full factory reset/ROM recovery: I lost the "IGO Navigation" app, sample music and video files and not sure what else that came with the unit. Oh well.

Appreciate any help!

Thanks!
