When Jolla were unable to supply the Jolla Tablet I'd ordered, I used the refund to buy a Nokia N1 on Ebay.

The N1 comes in two versions, the initially released Chinese version and the more recent Taiwanese (sometimes referred to as the International) version.

The main difference is the "Store" included with the device.  The Chinese version has a Chinese Store where most apps only have the Chinese characters and there isn't the range of apps as in the Google Play Store. The Taiwanese version has the normal Google Play Store plus other Google services not present on the Chinese version, e.g. Google Maps.

My tablet has arrived and it is the Chinese version.  This means its use is severely limited as I cannot install some apps I was planning on using.

I have have contacted the seller to see if he will replace it with the Taiwanese version.

Meanwhile I'm looking at my options in the event the seller will not replace the tablet. One option is to install the Taiwanese ROM.

There are some threads on the XDA developers site about this. While the process doesn't appear to be all that difficult there seems to be a high level of errors/problems experienced by some who have tried installing the Taiwanese ROM.

I did say the process looked to be straight forward, but I've never done any rooting on an Android device before (I've done similar on other devices). No doubt there are parts of the process that are taken for granted by those used to rooting Android devices that could be easily over looked by a newbie.

What do the experts on here think about the probability of success in installing the Taiwanese ROM? Are the problems experienced by some people likely to be related to these people not following the process properly? 

Is there anything I need to watch for if I decide to root my N1?

Thanks in advance for your help.
