Google always looks after the Nexus range when new firmware comes out as flash-able, but one of the major gripes people have is that is comes out with the ADB sideload method instead of just an ordinary flash method. Some are fine with that, but others find it too confusing, so they leave it and just want for the arrival of the OTA. We find that a bit sad and after doing some reading today a new way of checking the update has come to light using ClockworkMod recovery or TWRP recovery. Now this still doesn’t make it as easy as a regular official firmware update using Odin because you obviously need a custom recovery. Note that it doesn’t mean you need root. We want to have the stock Android 4.4.3 installed right now, or this will not work.
Only use this guide if you are running the stock KTU84L 4.4.3 firmware that released only a matter of weeks ago. If you upgraded the software recently whether it was over the air or manually then, this would be the right firmware. You can double check what software version you are running by navigating to Settings > About device > build number and software version in this list. Make sure it matches up with the numbers and letters I put in the start of this paragraph.
It is obviously only good for the Nexus 10. Each Nexus device has a different number, and they all need a unique guide. Failing to listen can result in a bricked phone or tablet, and it is a nightmare to try and fix if you have no experience in doing it. Thankfully these days developers are good enough to create solutions but it won’t be attached to this guide so you’ll need to look out for it elsewhere.
There is a guide out there for the locked bootloader using ADB but this guide is for the unlocked bootloader. As long as you can achieve that and have some experience with one of the aforementioned recovery options it should be sweet.
The Google Nexus 10 might sound new because the number is high, but that is because of its tablet origins and not smartphone size. There’s no relation between age this time and as such you will have trouble finding USB charging as an option. That means it won’t charge when plugged into the computer. Make sure you have at least 60% battery power remaining before you start this guide. That will ensure that it gets through the procedure without turning off on us. Turning off is a dangerous thing, and we want to avoid this at all costs. If you think your battery might need more (keeping in mind we expect this to take no longer than 15 minutes) then charge it up to give it some extra juice.
When brand new the battery capacity is 9000 mAh and gives 20 days standby time although we expect that amount reduced because of its age should be starting to show if you use the tablet frequently.
If there is any modification installed on the tablet at all on the OS, it will cause a brick situation so make sure, it is on nothing but stock firmware.
Take the time to visit the Develop Options section and enable the USB Debugging mode if it isn’t already showing with a mark in its box. You also need the Google Nexus USB drivers.
One of the things we took away from the Google I/O event today was the Android L Develop Preview and in particular the changes that Google is implementing. The one feature that could change the way we do guides in the future is security. There are a new Universal Data Control station and built-in malware protection. However, we are not running that yet, and people still might be using anti-malware and other security applications on the Android-based OS. If you, please put a stop to them for now until we finish here because they can interfere with what we are doing.
