Updating the 8277L_Demo or the APLS 8227L android headunit.
The MTK8227L is a processor type of chip first produced in the year 2013. In its day it was groundbreaking, low cost and a (then) massive 4 cores to run Android.
Unfortunately the years have moved on and processors for android headunits are now many times quicker than the old AC8227L chip.
The MCU
The MCU in an android headunit, including the 8227L is the overseeing Micro Controller Unit (MCU). It is a processing chip with some supporting RAM and I/O. This is a mini computer on a microchip. This microchip and its RAM is what runs android and does the control of the headunit functions.
More Speed
Owners of the quad-core 8227L based android headunits want more speed, to keep up with the modern apps and even just modern expectations of what android can do based on the latest mobile phone.
Lack of RAM
The 8227L ALPS and 8227L_Demo units are only equipped with a maximum of 2Gb RAM, but many only had 1Gb and faked. RAM will be a very limiting factor for your android headunit. Modern Android is hungry for RAM. While back in the yesteryear of 2013, 1Gb of RAM was sufficient and relatively expensive, move on the the current year and 1Gb or even 2Gb RAM is too little. The limit on 8227L RAM is not the cost of it as the price of RAM is dropping. The 2Gb limit is hard wired into the fabric of the 8227L chip. The 1Gb RAM +fake 2Gb description is just thoroughly dishonest and nothing to do with the chips themselves.
More Clock Cycles
More clock cycles and more cores is how the processors make such leaps in performance every 18 months. New Processors are produced that are quicker and often more power efficient than the previous generation. More clock cycles = faster android headunit. It is the same processing power that you are aware of in you phone. Every next generation of phone is quicker than the last, apps demand it, users demand it. There is no difference with the android headunit, if you want it quicker, get the later generation, just as you would with a phone.
Stuck in 2013
Unfortunately the 8227L ALPS Demo SoC and its other names is still being produced to the original 2013 specification. It is running a limited 4 cores at a low clock speed of around 1.1Ghz. These junk chips are still being used to dupe people when they are fitted to power an android headunit. If you think a quad core is sufficient for your needs and you are happy with 2Gb RAM, think again, think if you would be happy with a phone from 2013 to use today.
8227L MCU updates
Confusion reigns high due to Microsoft teaching people to update the software to fix problems. There are many that think an update to the software, or the firmware in the MCU will fix the lack of clock cycles. It won’t. The MCU firmware runs in the MCU chip that runs the functions of the head unit. To get a faster headunit, you need a faster processor and more RAM. Updating the MCU with different firmware won’t make it faster.
MCU update problems
Updating the MCU is loaded with potential problems and zero gain. The MCU can be corrupted during the update or quite commonly the wrong file is installed. In the mistaken understanding that all 8227L Demo ALPS units use exactly the same firmware the file from one model is incorrectly flashed into the headunit and you end up with a bricked 8227L.
Don’t Flash
Don’t update the ALPS 8227L, MTK8227L or 8227L_DEMO units in the expectation of a fix. You are much more likely to do some serious (as in irrecoverable) damage to your android headunit. Flashing firmware off the net is a good way to stop the thing from working. There is no windows CD you can borrow from a friend to reinstall the good MCU firmware for an android headunit, it just does’t work like that. If you mess up the flash, you have very few ways to get it back to working. Did you take a back up first? Do you know how to restore it?
Do Factory Reset
You may just be better off to (although this can have its own problems) factory restore the 8227L_Demo. This procedure is used clear out the junk and the good apps then just reinstall the few good apps you need.
2013
But the ALPS DEMO 8227L will still be technology from 2013, no matter what you do to it.

. Updating this to make it quicker and more reliable?){kind=link}
I have a few 8227L AHU’s. They do (pretty much) everything I need a “Car Stereo” to do. I would not like it as a dedicated tablet, but it will run my GPS apps, Torq app, make phone calls, play MP3’s from a micro-SD card, and stream music from my phone as I am driving my car. I just started using Android Auto and this seems to be installed on many older AHU’s in order to sell the old stock sitting on the shelves. I just wish I could update my 8227L with the firmware to run AA or CP.
