Zenfone 4,5,6 is Intel Cloverview based Devices.

Replacing eMMC of this type of Devices is easy using UFI.
The most different of intel cloverview based devices is, they using GP1 in eMMC.
Lets check out how to replacing eMMC Asus Zenfone 4 below.

Preparing new blank eMMC.

Commonly we using Samsung KMVTU000LM-B503, but most emmc with bga 153 is supported.
Download Dump File in support page.
Write only ext_csd to enable GP1 partition.

And just click Yes in Confirmation Dialog

Now write only boot1, boot2, and GP1 image, without user area.

Now resolder emmc to board, and assemby the devices.
When everythings ok, your Devices will vibrate shortly and show USB logo

Connect USB data cable, device will detect as Cloverview Devices in Device Manager

Now Debrick devices using Ufi Android Tools as pic below

After debrick success, your devices will restart and go into Fastboot Mode and Ready to Flash

Flashing complete, now wait until Devices fully working, enable USB Debugging its time to Root using Ufi Android ToolBox

After Root complete, we are ready to repair imei.

please help my zenfone 6 a600cg want to change with KMVTU

first problem is the emmc already have samsung rom ... should i erase all first ?is it okay?

second, i tried to erase all then do as your instruction flash ext_cd, but its not unlock gp1 checklist. should i reflash the samsung ext_cd boot1 boot2 to unlock gp1 bar(because its gray out)?

third, i have managed to flash ext_cd,boot1,boot2,gp1 ... and gp1 its not the same as picture gp1 size is 8MiB (enhanced) ... is it okay ? because i got problem when debricking and before debrick its vibrated when i plugged in the battery then i push power on and my zenfone 6 shows just black screen( not usb logo) but it can enter cloverview(seems abnormal) plus as i see on device manager...

fourth, debricking was stuck on FW download aborted
