Ug007ii updating rom
TWRP is a great custom recovery that enables the use of touch and other nice features that have much of the ROM development world captivated.
ROM Manager also supports incremental ROM updates, so developers can issue smaller upgrades whenever bug fixes or small feature updates need to go out.
On phones with EXT4 blocks it doesn't get out (as a rule). Here the options depending on a concrete phone are possible.
Maybe it is necessary to press at the same time with connect of a cable the camera or volume buttons.
or following: In case of problems in operation with SPFT it is useful to listen to a sound on PC and to open a Device Manager.
On some MT6573 models, for example on B63, it can't be executed with any combinations and only testpoint need!
That will surely work because normally recovery images are unsecured.
It means that on phone superuser is installed, in this case connection indicator in bottom left corner of program has yellow color.
Button is greyed-out when phone is not rooted and/or an unsecure adb connection is not established.
If you already have a CWM-based recovery you can also boot into recovery mode, connect the phone to the computer and then use MTK Droid Root & Tools to create the backup.
