wonder which device to blame

Today our family is driving to Toronto, and I found this the perfect moment to try out thethering feature of my Roger iPad mobile phone plan.  So I turned on the Personal Hotspot feature on my Galaxy Nexus.  MyPad 3 and my Nexus 7 was able to pick up hotspot, but not my Microsoft Surface device.  I was puzzled, and kept trying various options.  Eventually, I yanked out the SIM card, and use it on my iPad 3, and use iPad 3 as personal hotspot.  Now, all my devices, including Microsoft Surface, are able to access Internet.  So I am pretty puzzled now.  I don't whether I should blame my Galaxy Nexus lame at being a personal hotspot, or Microsoft Surface sucks at accessing personal hotspot.  But at least I am glad that I have various devices to try out different options.

So I can still root after 4.2.2 update on Nexus 7

I was so used to accepting all the update on my Galaxy Nexus phone that I did the same on my Nexus 7 when a 4.2.2 update alert popped up.  Only after then I realized that the N7 was, once again, unrooted, and I lost one HUGE feature on my N7: watching video directly from thumb drive.  So now I need to find a working rooting instruction for Andorid 4.2.2 on Nexus 7.

Luckily, the old one that worked is still working as long as you follow a few lines of instruction on the site to make it working on 4.2.2. .  I tried and it worked pretty well.   So ... I am happy again :-D .

Rooting Nexus 7 ... again ...

I didn't realize that rooting is not a one shot deal.  I thought once I applied root to an android device, it will stay rooted forever.  Most tech genius on the net will read this and poke fun on my stupidity.  Yep, making mistakes, and then learned from the mistakes.  That's how civialization get birthed and evolved.  You are welcome.

Anyway, I figured it out a few days before I my trip to Canada, and found that my Nexus 7 couldn't recognize the thumb drive I hooked to the device, and thus couldn't play the videos on that thumb drive.  Not good, consider how many hours of boredom I need to endure during the whole trip.

I rooted the Nexus 7 back when it was JellyBean.  Now the system already updates to 4.2.1.  So I guess I have to do rooting again.  The good thing is that since I rooted once, I don't need to wipe my device to root again.  So found this tool called "Nexus Root Toolkit v1.6.2" (NRT_v1.6.2.sfx.exe), downloaded it and installed it on my Lenovo S12 Windows 8 OS device.  Problem came as the app didn't seemed to work.  Searched the web, and found out that the app and the driver it uses had problem on Windows 8.  No problem since I kept the Windows 7 partition exactly because of this kind of situation.

So I installed the app, and this time I found that it bitched about missing Nexus 7 driver.  No problem again, because I had it in my shared drive (usb_driver_r06_windows.zip).  After that I followed the instruction, and eventually got a rooted Nexus 7.  Now I can watch video during my Canada trip.  Yeah.
