Update Xperia ZL with CM 11 Android 4.4 KitKat custom Firmware

Sony launched the Xperia ZL this yr on March and even supposing we face with a excessive finish Android based totally smartphone in a position to operating the most recent options, apps and capabilities, the telephone remains to be caught on Jelly Bean OS. Moreover, Sony introduced that the OTA Android four.four KitKat replace will probably be rolled out for the Xperia ZL all the way through subsequent yr – February or March if we’re fortunate – so except then there’s no KitKat for the ZL customers. However you could make a choice to alter this, because the unofficial port of CM eleven has been made on hand in your software.

As that you could already inform, CM eleven is being in keeping with Android four.four KitKat OS although the pure Android tool might not be put in to your Sony Xperia ZL. CM11 is a customized ROM that includes its personal options and appears, this means that that you are going to be playing a personalized variant of the inventory Android four.four platform. Additionally, remember the fact that this model of CM11 is just not reliable, so we’ve a modified firmware that has been custom-made by means of 1/3 birthday party devs particularly in your Xperia ZL. These of xda-builders are being accountable with the identical, so now we have to thanks them for this tutorial.

Now, all over the rules from beneath we can be checking on the right way to set up Android four.four CM eleven customized ROM firmware to your Sony Xperia ZL. The flashing course of isn’t exhausting to finish, making use of the instrument taking only some minutes out of your free time. However, this information isn’t displaying an reputable process, so do believe the current operation complicated and likewise unsafe. On the identical time if in case you have made up our minds to complete this step-by-step information, you’re going to first have to organize your handset, the pre requisites being somewhat a lot of – we will be able to speak about this in a minute so be endurance.

As I’ve talked about prior to this isn’t the professional CM eleven firmware; the CyanogenMod continues to be engaged on growing a steady Android four.four KitKat instrument for the Sony Xperia ZL. Anyway, the devs who’ve created this firmware ensured you could safely flash the ROM for a day-to-day use. In reality, folks that have already put in CM11 on Xperia ZL declared that the platform is working easily so there are not any main bugs or issues that aren’t working.

This information isn’t reputable and on account of that (and as a result of the pre requisites from beneath) the guarantee of your smartphone will get void. By using making use of the CM eleven firmware the binary flash counter will likely be elevated and you are going to lose the guarantee of your cellphone. If you’re going to need or wish to repair the guarantee, you’ll have to make a choice to downgrade to inventory Android Jelly Bean OS (by means of PC Partner) or to stay up for the Android four.four KitKat OTA replace to be pushed out. If you’re anticipating the OTA unlock of Android KitKat then remember that the identical is probably not noticed by using your telephone – you’ll have to manually set up the legit replace through the use of an appropriate tutorial.

If you wish to safely full the rules from beneath, to start with you’ll have to unlock the bootloader of your Sony Xperia ZL. Do that as without unlocking the bootloader you won’t be able to gain root access, which is the second thing you need to ensure before applying the CM11 Android 4.4 custom ROM firmware. After completing these two procedures, the system of your handset will be unchained and you will be able to access the same in order to flash a custom ROM. All these are unofficial procedures, so be careful when applying the same and try not to mess things up as you can end up in bricking your Android based device.

Up next, you need to install the latest version of CWM or TWRP recovery. CM11 has been tested on the Xperia ZL only via the mentioned apps, so that’s why I recommending you to use the same. TWRP is the touch version of CWM recovery, so you can use any of these two tools. You need to install and use a custom recovery image instead of the stock one because, the custom app is offering an intuitive user interface that can be used when trying to access the internal system, and that’s how you will be installing the Android 4.4 based CM 11 firmware on your Xperia ZL.

At this point you should make a Nandroid backup by using the custom recovery image you just flashed. By doing this you can save the current ROM, as if you will not like the new firmware you will have to apply a software that has pleased you. The restoration process can be easily performed as there won’t be required a complex guide like this one. On the same time I strongly recommending you to backup the Xperia ZL data because a wipe will be required – without wiping the data and clearing the cache you will not be able to properly use CM 11. Do the backup by using suitable backup and restore apps from Google Play – don’t worry because the tools are free distributed ones so you don’t have to spend your money on anything.

Good, now all you have to do is to make sure that you can use a computer – the required files will be downloaded on the same PC. It is indicated to disable (only temporarily) the antivirus or any other security protection that is installed on your computer and on your phone because these tools might interfere with the update operation. You will also have to connect your device with the PC – because of that on your Xperia ZL the USB debugging option must be enabled –achieve that by going to “menu – settings – developer options”.

Take a look on the battery status of your smartphone. If you notice that there is less than 60% power left, you need to plug in the charger. Installing CM 11 will take a few minutes and if your handset gets turned off in the middle of the flashing process, you will risk in bricking your handset. Also, this tutorial is compatible only with the Sony Xperia ZL which means that the steps from below are working only for the mentioned phone. Don’t use this step by step guide for installing CM11 Android 4.4 KitKat on another smartphone or tablet.
