Thank you for attention
But I've got the program and tried it but I'm Want Download Install A Custom rom android 4.3 or 4.2, but do not know Download in my phone
Are you trying to flash a custom rom after installing the L9Recovery.apk? The apk installs a 2nd init version of CWM. You can't flash custom roms with this type of recovery. Not much more advice to give with unlocking the bootloader....just keep trying. I gave up, to be honest.

Unable to flash CUSTOM RECOVERY!

I'm using a VIVO y22 device. It's internal storage is too low & so I want to root my phone to extend its internal storage. But I'm having problems in rooting the device.
NO automatic rooting softwares are working on my device. Tried several of such softwares.
So in order to manually root the phone I need the help of Custom recoveries. I generated a CWM recovery file for my device using the MTK droids tool since my device is an MTK device. (MT6582)
But I am unable to flash it on my device. When I tried to flash it via fastboot (with all the adb and fastboot drivers properly and installed and well verified) with the command: Fastboot flash recovery (filename).img, it showed the following error: Partition recovery not support flash.
I then tried to flash the recovery img using SP flash tools with the proper scatter file of my device well loaded. It too showed an error: PMT changed for ROM it must be downloaded.
The question is that is there any other method for rooting my device?
If not can you please guide me to solve the problems that I am facing while trying to flash my device with the recovery image?
I have previously rooted 4 devices successfully and have flashed custom recoveries in all of them.
But I can't root this device. I can't search online for help with this specific device as it is unpopular.
Here are the details regarding my phone:
BRAND: VIVO
Model : Y22
Manufacturer: BBK
Software Version: PD1309W_EX_A_2.7.3
Kernel Version: 3.4.5
Compile time: 6/4/2015
Operating System: Funtouch OS_1.0
Android Version: 4.2.2
Mediatek Version: MT 6582
Here are the details that are shown about my device in the MTK droid tool:
Hardware : MT6582
Model : vivo Y22
Build number : ALPS.JB5.MP.V1.6
Build date UTC : 20150604-135456
Android v : 4.2.2
Baseband v: MOLY.WR8.W1315.MD.WG.MP.V11.P19, 2014/12/18 20:35
Kernel v : 3.4.5 ([email protected]) (gcc version 4.6.x-google 20120106 (prerelease) (GCC) ) #1 SMP Thu Jun 4 21:45:55 CST 2015
I am thus kindly requesting you guys to help me regarding this root problem I am facing with my device.
Thanks in Advance.
