[TUTORIAL] How to backup your Cherry Mobile Ultra full Jellybean firmware before upgrading to Android Kitkat
Cherry Mobile announced and posted the official Android Kitkat 4.4.2 update on their website and I have created a full tutorial on how to update to Kitkat and it’s very easy simply follow my video tutorial. But before proceeding with my video be sure to back up first your Jellybean firmware so just in case anything went wrong you can revert back to jellybean, just follow this steps.
BACKUP FIRST BEFORE DOING ANYTHING ELSE
STEP 1 : Download the Roadkill image on their website , on the download section select the operating system that you are going to use, on my end I am on a Windows 8 platform so I need to download the file that is compatible for Windows 8 and click download
STEP 2: You need to turn of your phone and boot the QPST MODE, to access that you need to press and hold volume down + power button for a couple of seconds and wait for the capacitive buttons to light up and then plug your USB to your computer and wait for it to automatically detect the driver, if it ask you to FORMAT the disk just IGNORE/CANCEL that window.
STEP 3: once the phone is detected you will notice it will have a removable drives on your computer , so now open the ROAD KILL DISK IMAGE.
choose STORE IMAGE tab and on the read image you will see it will have a new partitions which is around Physical Disk 7.28gb in our case that is the Cherry Mobile Ultra.
STEP 4: next is to click the browse and rename the file of your backup I recommend naming it with this naming file convention[filename]-[date]-[time] so once done click the START button and wait for it to load
it may take awhile to finish doing the backup because of the capacity take note that it’s a whole image rom it will include all the files of your phone even the IMEI and personal data’s you have on your unit, so usually I do not recommend sharing this file to others unless you know how to modify the files.
I also recommend doing the backup 2–3 times so in case the first backup might be corrupted you will still have a backup of your whole ROM.
after doing the backup you can now proceed on the Android Kitkat Upgrade
be sure to double-check your files or else you will end up a dead phone when you restore a corrupted file.
TIP: BACKUP YOUR PHONE WHEN YOU HAVEN’T INSTALLED ANY APPS YET
there are other methods of doing a backup but it needs more technical skills so far this is the easiest way to back up your ROM on a Qualcomm processor .
