mihione · Dec 13, 2016

I read some articles which mention we can flash every soft on every variant,but its really working and dont get brick?Somebody tried it?
I want to update the chinese to us rom,because the more frequently updates.

I can't post a post, not too sure why but to answer your question, I recently has my A2017G model updated to B07 by a service staff, had it downgraded back to B02 because B07 never existed on Global models. And, A2017 seems to have B07, so my guess is yes, you can. But it looks kind of risky, u might have to ask the person who created the USA model and the China model

Thanks!Here is a lot of unclear things like the bootloader unlock methods and compatible software things for the global and chinese version.

Make sure to not flash the radio, whatever you do.

You just need to flash Boot+System, and DON'T Flash bootstacks from other variants.

If you want Root you need to have Unlock Bootloader otherwise you are going to be able to pass ZTE Logo and have what we call softbrick

On the contrary, I successfully flashed the Chinese B13 rom to US hardware (A2017U) and it works normally. I think it may work in the same way for your case. Just need to modify the META-INF/com/google/android/updater-script to include flashing boot.img and system.new.dat only. Here's an example:

getprop("ro.product.device") == "ailsa_ii" || abort("This package is for "ailsa_ii" devices; this is a "" + getprop("ro.product.device") + "".");
show_progress(0.850000, 180);
ui_print("Patching system image unconditionally...");
block_image_update("/dev/block/bootdevice/by-name/system", package_extract_file("system.transfer.list"), "system.new.dat", "system.patch.dat") ||
abort("Failed to update system image.");
show_progress(0.050000, 1);
package_extract_file("boot.img", "/dev/block/bootdevice/by-name/boot");
set_progress(1.000000);

Backup first, and it's at your own risk!

BTW, I have twrp installed so I don't need to resign the modified zip file.

I have the ZTE Axon 7(a2017) in order for me to use the a2017U software all I had to do was download the a2017u stock firm from the ZTE website and follow the instructions in the zip folder.

And everything works? No issues? Did you flash it by putting it on the internal memory and hit update software?

You are correct, the B29 factory package has no assert checks, it will just blindly flash over, but it will flash the U modem as well so its interesting to see if it messes with radio bands. What region are you using it in (US and what carrier) and is it working as expected?

Code:

ui_print("Target: ZTE/P996A01/ailsa_ii:6.0.1/MMB29M/20161014.114339:user/release-keys");
show_progress(0.850000, 180);
ui_print("Patching system image unconditionally...");
block_image_update("/dev/block/bootdevice/by-name/system", package_extract_file("system.transfer.list"), "system.new.dat", "system.patch.dat") ||
  abort("E1001: Failed to update system image.");
show_progress(0.050000, 5);
package_extract_file("boot.img", "/dev/block/bootdevice/by-name/boot");
package_extract_file("ddr.img", "/dev/block/bootdevice/by-name/ddr");
package_extract_file("xbl.elf", "/dev/block/bootdevice/by-name/xblbak");
package_extract_file("lksecapp.mbn", "/dev/block/bootdevice/by-name/lksecapp");
package_extract_file("rpm.mbn", "/dev/block/bootdevice/by-name/rpm");
package_extract_file("tz.mbn", "/dev/block/bootdevice/by-name/tz");
package_extract_file("echarge.img", "/dev/block/bootdevice/by-name/echarge");

package_extract_file("adspso.bin", "/dev/block/bootdevice/by-name/dsp");
package_extract_file("recovery.img", "/dev/block/bootdevice/by-name/recovery");

show_progress(0.100000, 10);
format("ext4", "EMMC", "/dev/block/bootdevice/by-name/userdata", "0", "/data");
set_progress(1.000000);

Can you flash the G variant like the U variant, a straight flash?
