Where do I go to turn off nand / system write protection?

Outstanding work, brother. Amazing. ZMAX.

Your method works perfectly on my Z955A. I have root and am happy. I've been a fan of yours since my ZTE Warp days. Thank you for your hard work and dedication. You rock!

Edit: I use MetroPCS and their hotspot tethering. Rooting breaks tethering. I'm not sure whether it's just being rooted or using Kingoroot that caused the problem. I think it's Kingoroot. Since unrooting, my tethering has gone back to normal. If you use a Z955A on Metro, and use wireless tethering, you may want to hold off on rooting.

You might try apps such as "Portable Wifi Hotspot" in google play to see if they work for tethering when rooted. You can also add "net.tethering.noprovisioning=true" to your /system/build.prop which tells it to use the same apn for tethering that the phone does. This gets around some blocks. *only do this as a last resort until someone builds twrp for your device because editing the build.prop improperly can cause your phone to go into boot loops. If you can get twrp on the device then take a full backup first and it's simple enough to restore if things go south.

Would anyone be willing to walk me through this for my ZTE Grand X 3. I really want to root this device but I'm not very savvy with rooting. I'm computer literate and can accomplish most tasks but this is beyond me.

I wonder if the new zmax pro uses the same protection as the z958...might improve our odds of getting a fix. I tried rooting it via kingroot, going into a root adb shell and trying to write boot to recovery..looks like it worked but doesn't actually write it. Oh well.

I sure as hell hope not.

I'm really having trouble rooting my ZTE Prestige. Ive tried multiple times and failed. Would someone mind emailing me and giving me more specific directions to root my phone. My email is mcowell00@gmail.com I'd really appreciate if someone could help me root it. Thanks

turns out it works on the zte speed too... great work hroark

btw... anybody know what the situation with the kitkat bootloader is on this thing? tried a twrp it didnt work, tried a repacked stock that was just slightly modified only changed some comments in the fstab no actual code im pretty sure but i had to have bcrichester do it i dont have a build setup anymore. but i managed to get root going, permanent, this plus kingroot, just need to figure out whether we can get a recovery working or not

run this command in adb shell or terminal

reboot disemmcwp


to re-enable write protection issue this command

Just want to say this Works for the ZTE Axon 7 - A2017U -
thank you a bunch

Hello @hroark13,

This did not appear to work on ZTE Citrine Z716BLB01 running Android 5.1.1.
I tried both before and after temp root with KingRoot v4.9.6.
Here is the output of my build.prop (don't know if this info helps or not)

Surely there's something in here I can exploit to gain permaroot?

Would you happen to know where the rw prevention is coming from?

Doesnt seem to work on Z988

Any chance you could take a look into the Z988 hroark13? The kernel source is available if that helps any

Is the z988 (Grand X Max 2) even rooted? You can't even know if it works unless the phone is rooted.

No its not rooted. Thats what im looking for is root. The op said run that comnand and then try root app, so thats what i tried to no avail. My misunderstanding

We need to get a rooting app made that uses the quadroot exploit.

No the command only disables the system write protection (on some zte devices). Writing to the system still requires root though. Also, disabling system write protection won't necessarily make a root app work magically. Also, rooting a device that is running marshmallow or nougat doesn't even affect the system partition at all. Your superuser app goes in /data/app and all the binaries go to the boot partition instead of the system.

Can't wait for root for z988.. wish I knew how to help.......
