Ken's Tech Note

Problem: LG G2 D802 was rooted and a custom recovery package TWRP installed. OTA says there was an update. After applied, it goes into an endless bootloop - always stayed in TWRP. Fix: http://forum.xda-developers.com/showthread.php?t=2451696 Install Android SDK that will give you access to ADB shell tool. Run the following commands: adb shell dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota Then reboot the phone within TWRP. This has fixed my G2 twice.

One of the best things of using Nexus is that it gives you the most up-to-date Android release as it becomes available very quickly. The Nexus 7 was updated just a few months ago with Android 4.3 and it just finishes another upgrade(s) to 4.4 then 4.4.1 then 4.4.2. All delivered OTA and the N7 is rooted. Running Antutu Benchmark shows that it allows the system to run slightly faster than with 4.3. We should be aware that Antutu itself has been updated to run on newer Android system - we can only assume we can still compare the results with older releases. There are other discussion of what's new on 4.4. I am most concerned that Chrome is not shipped with Andorid 4.4 to carriers and end users would need to download it from Google Play themselves. This might not be a bad thing as explained here . That said, it is interesting to see which browser carriers would ship and the testing matrix for mobile web apps would still be complex.

Nexus 7 has received Android 4.3 recently. Overall, the tablet works a bit snappier, similar to an optimized ROM "Purity" ( download from here .) which is on 4.2.2. Chrome, the default browser, has upgraded to v 28.0.1500.94. Antutu v3 benchmark at 12,662. The performance is good and I am very pleased with this piece of hardware is already 8-9 months old.  

Acer has begun to roll out ICS for its Iconia A100. I got a cheap (perhaps display unit) from the US at around US$200 about half a year ago. Absolutely happy with it. Now with ICS, it is even better. If you can't wait for its official rollout, google the relevant terms (at XDA) and download the ROMs there. The version I originally downloaded was v1.012. I subsequently overwrote it with v1.014 and everything is good.

The maximum connections by default is 40 which is not enough in a small office who are using Thunderbird (as by default a Thunderbird client will occupy 5 connections) 8 accounts will occupy all. It is possible to edit the following parameters and settings to a larger value. MAXDAEMONS=40 MAXPERIP=40   Under Ubuntu, the settings can be found at /etc/courier/imapd. Remember to restart the service to activate the new settings.
