I am not sure if this is the right place to post this so please bear with me.
I have an 8" Onda V812 Tablet with IPS Touch Screen and Android 4.1 with 16GB HDD, 2GB RAM and Octocore graphics. It is lovely tablet and I am very pleased with it.
I was notified of an upgrade to Android 4.2 which I have now downloaded (640Mb) it has full instructions but it is all in Chinese even the graphics, so I am hesitant to do the upgrade without a clear understanding of what I am doing so I attempted a translation using Google but it is still very clear
There is a folder with 3 files :
PhoenixSuitV1.0.6_CN.msi (which I think has to be installed on my PC)
V812Core4_v3.2_v1.img (the update image)
请一定先打开看本文档！！！【刷机教程】.doc ( instructions)
1) Is the upgrade improvements worth the risk of failure and possibly "bricking" my tablet?
2) How can I get a clearer understanding of what to do; i.e. is it much the same as adding a third party ROM?
I am worried about doing the procedure because I am in my 70s and not well off and I struggled to buy the tablet in the first place.
Could someone give me some advice please.
