NexusS – Issues post upgrade to Android 4.0.3

Post official upgrade to Android 4.0.3 and the scare couple of days earlier this post is of the issues that am facing.

1. The mobile network signal drops lot of times. Some times, the network is not found till a reboot is done.

2. Battery never says 100% charge complete.

3. Worst of all. Last night after battery drained, my mobile got switched off. Today morning I put it on charge and switched it on. Shocks of shocks, the mobile network is missing. Reboot still no network. Change mode to Airplane and again disable but still no network.

Worst of all, none of the service providers are also listed.

This is the most funniest thing I would have done. Went to System Settings -> Wireless & Networks -> Mobile Networks.  Disabled Data enabled, Data roaming, Use only 2G networks. Then clicked on Network Operators, finally my mobile service provider was listed in the available networks. I select and then enable all the disabled options. 

Back to normal. Back to work. 

Any further issues will be added here.

How my Nexus S went from dead to alive

After upgrade to Android 4.0.1 last month. When I read the post of official Android 4.0.3 update, I also wanted to do an upgrade. After following the steps mentioned, I did exactly the same. Download, copy file and rename to update.zip!

Only that the upgrade to 4.0.3 never happened. Further research on net followed. Somewhere in one of the articles I read that upgrade happens from 2.3.6 to 4.0.3 which is official.

There I go downloading 2.3.6 and installing. Now everything goes for a toss. The phone when rebooted started giving the message “android.process.acore has stopped unexpectedly”. It wouldn’t go beyond the screen of saying touch android for starting.

When I press “Volume UP & Power” button together I get into bootloader menu but when I click on recovery, I get an exclamation mark and nothing happens beyond.

When I connect the USB cable to my laptop, I can view the files inside the mobile, can copy into the mobile or copy out. But the laptop device manager would not recognise the phone.

Again I go into researching the entire internet android domains looking for solution. I end up installing Android SDK, downloading umpteen files to be installed in the phone. Then I try to install PDAnet. Check & read every post on android forums, watch every video.   

After installing every other file, I try fastboot command. But the command prompt issues a message “waiting for device”.

If I type adb devices in command prompt there is no result. Basically my phone was not getting recognised. 

In one other post I read take the battery and leave it out for 10mins and again put it back, it will work. This looked dumb to me, still I followed. 

I should say though that it was after I felt this was dumb thing to do, did I get an idea to get it working. Like they say, one last attempt. 

I put the battery, switch it on, see the message “android.process.acore has stopped unexpectedly”. Shutdown the phone. Press “Volume UP & Power” button together.

Click on Recovery, I find the same old exclamation mark. The theory that removing the battery, leaving it out for 10mins, and then putting it back, was not a solution for my phone.

When the phone was displaying the exclamation mark, i got an idea voila. I press again “Volume UP & Power” button together, it took me to the recovery mode in forced way!!

I know the file “update.zip” did not upgrade my phone earlier, so I select CynogenMod9 files and install them. Its even more frustrating because you know you have reached close to solution but the solution is not there still. When I installed CM9 files, my phone spat saying “Installation Aborted”. Try another file same message. I start looking for CM7 files now. Same result.

One final brain wave, my 6th sense woke up & I clicked on “update.zip”. Wonders of wonders, the installation happened successfully. Though that 2mins of installation my heart was racing & pumping. I reboot the phone lo behold, watching very carefully & yes phone is up!! I sync the google account and the old apps that I had installed earlier are all back too… 

Now my NexusS is on Android 4.0.3!!!
