I bought a budget Android tablet a little while back that turned out to be really rather good. However, there were issues with the initial firmware.
Ployer released a firmware update in November 2012 and again in April 2013 which addressed these issues. Here's the translated change log.
- Increase the volume buttons on the vertical screen.
- System, audio and video decoding, browser, Flash player, 3G module, boot animation module BUG repair.
- Update NandFlash, Mali, Wifi module drivers, while addressing some CTS tests BUG and the stability of the system as a whole has been further enhanced.
- Optimize Flash stability, improve the efficiency of the implementation of the DDR.
- Default input method Sogou input method.
- Update Google Pinyin input method.
However, the official Ployer firmwares come pre-loaded with a selection of Chinese applications and defaults to a Chinese language.
I decided to have a go a making my own custom firmware for the Ployer Momo8 IPS with the following goals.
I think I've been fairly successful. My firmware includes Android 4.1.2 features and even some Android 4.2 features. Until someone successfully ports cyanogenmod to the Ployer Momo8 IPS or Ployer release a 4.2.x update then my firmware is the most complete "Google Experience" you'll find for the device.
Below are the changes I made to the official Ployer Momo8 IPS firmware.
This release is mainly a fix for Google+. The builds are running now and will be available for download later today.

put into this custom firmware recognised. I don't ask for much, it is at your
discretion, but just think how happy I'll look when I am sipping the beer you bought
You'll need Rockchip Batch Tool which include the RockChip USB drivers and the firmware flashing utility. I've modified Rockchip Batch Tool to default to English language and removed old logs and transient data to reduce the size of the download. You'll also need the firmware itself.
Download Rockchip Batch Tool and the STOCK RECOVERY version of the ROM. Unzip both archives once they are downloaded.
Flashing this ROM will will effectively factory reset your tablet, wipe your installed apps, app data and preferences. If you have rooted your tablet you might want to consider making a backup with Titanium Backup * root. If you have not rooted your tablet then you could use Helium - App Sync and Backup.

/mnt/sdcardis the internal memory, not the microSDHC card inserted in the card reader.
The first boot may take a little longer than usual. You will be presented with the Welcome wizard where you can configure language and locale, etc. You can optionally enter your Google Apps or Gmail account credentials and doing so will prompt for which Wifi network to associate with.
I've also made a video showing how to flash the firmware. Frankly, the hardest part is getting the Rockchip drivers installed.

Booting to recovery can be achieved using the pre-install Quick Boot app.
The Ployer Momo8 IPS only has one hardware button (power) so CWM is controlled with gestures.
The Power button also acts as select, which I find to be the most reliable way to select an action.
Short answer, possibly.
Of all the WiFi networks I have access to, only one causes the Ployer Momo8 IPS to encounter weak signal and intermittent connections. When using the Official Ployer firmware on that WiFi network, connecting more than 5 meters from the access point is unreliable and maintaining a connection is almost impossible.
Using my firmware I can connect and maintain a connection up to about 10 meters from the access point. My testing, and the feedback from others suggests the my firmware improves the WiFi signal by 8 to 10dBm.
From my testing the Momo8 IPS appears to have issues with some wireless access points, possibly related to the chipset in the access point or the Momo8 IPS, but I've not been able to pin it down. That said, I've got access to 2 Draytek Vigor routers and the Momo8 IPS does not work well with either of them. Every other wireless network I've connected to works well.
For example, at home I stream 720p movies via DLNA over WiFi and watch them on the Momo8 IPS using MX Player. It works perfectly and never buffers or lags. However, your mileage may vary.
Short answer, it's the safest option.
There are 6 different ROMs (official or otherwise) that I am aware of for the Ployer Momo8 IPS. They all have slightly different partition layouts. If you flash one of my CWM RECOVERY ROMs over a ROM using a slightly different partition layout, it will almost certainly soft brick the tablet. The STOCK RECOVERY will always correctly format the partitions directly after a flash, thereby mitigating the risk of soft bricking the tablet.
Read the comments here, there are several useful tips. You can also use the comments here to see if anyone can offer assistance. Alternatively, go the Ployer Momo8 forum on Slatedroid, read what others have done and ask for help.
The differences Ployer made between 20130325 and 20121120 is not well documented. I did some additional analysis of what changed between the November 2012 and April 2013 releases from Ployer, you can find my notes here:
In addition to whatever Ployer changed, this is how my 20121120 differs from 20130325.
/systempartition on the 20121120 version is 375MB, therefore the following system apps are not included:
Some people have reported that WiFi is more reliable when using a firmware based on 20121120. Due to the size of the custom firmwares and the bandwidth they consume, custom versions of my firmware based on 20121120 are only available to donors.
