Root [GUIDE] ZTE vital/supreme Unbrick Guide

[stevestone]

Here we go,


Below are the steps to unbrick zte vital or supreme.

In case if you can boot up in recovery, please do data/cache wipe.. if not then its not an issue, This is required as we need some space in data partitions..


Hold volume up + power, It will boot up in FTM mode .. Make sure you have proper ADB installed. As it works fine with ADB and su..

please copy cwm recovery.img or system.img or boot.img in your relative path of ADB folder.

adb devices

See, If your devices get detected.

Then

adb shell
su
mount -o rw,remount -t ext4 /data
chmod 777 /data/media/
exit 
exit

After that for flashing recovery.img follow this steps..

adb push recovery.img /data/media/
adb shell
su
dd if=/data/media/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
reboot recovery

for system.img follow this steps.

adb push system.img /data/media/
adb shell
su
dd if=/data/media/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system
reboot

System.img will take some time, If in case you dont have space in data partition, Then please flash cwm recovery first then do factory format (data & cache wipe)

Our data partition have enough space to accommodate system.img
but after wiping it off..

Thanks..
Sorry for bad english

[B]adb shell[/B]
dd if=/data/media/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
reboot recovery

for system.img follow this steps.

adb push system.img /data/media/
[B]adb shell[/B]
dd if=/data/media/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system
reboot

its cuz you werent in adb shell after pushing the file, ive bolded the steps that steve should add to clarify for people

[stevestone]

thanks shabby.. Hey venture please see it again. I updated it... you are not doing su..

please do it from start again.. It works 100%, I tested..

 

[Ventrue05]

inbox me your paypal, id like to donate to you.

 

[Shabbypenguin]

haha whoops forgot to add su in that mix lol. sounds like he got it fixed that, thats good

 

[stevestone]

LOL.. I guess.. Actual gift should be given to developer JUNKIE.. for porting CWM..
I dont know his paypal email..

This might work for other ZTEs too. flash...

this should actually work on any 8960 or newer zte. in theory anyhow, cooldudezach also let me onto something that i believe he got from you shabby, that will allow you to recover from dfu mode, its slightly more complex of a solution that requires a dump of the entire internal chip as a whole, bootloader, radio partition, everything, but when youre down to nothing but a black screen and a red light you have little choice

i would however add in a rm command after the dd process, that way it deletes the system.img and/or recovery.img, and it could easily be turned into a script if you like. pack it all up and leave less room for user error

and i appreciate the thought but i cant accept donations, paypal sucks. i have a donation link but it wont let me take the money out without a bank account and i dont have a bank account... and im not really out bounty hunting here, if i was i wouldnt focus on ztes lol. i just wanna help the little guy, make sure that these budget phones dont get overlooked while every developer and their mom makes stuff for samsungs and lgs

 

[Shabbypenguin]

oh yea, about sdcard booting?

 

[junkie2100]

umm... that i dont know, something about the dfu mounting the entire internal chip in linux as a block device via usb or somethin

 

[Shabbypenguin]

yea i know nothign of that, i assumed you were talking about in the event of bootloaders being overwritten you boot off teh sdcard to get into dfu mode.

 

[junkie2100]

maybe that was it... i could swear i heard you mentioned, i also recall somethin about scary alien... i dunno it all kinds blurs together at this point lol

Make sure you have the usb drivers installed too. You can't run any commands without them.

What happened was i was messing around with the build.prop and i tried to delete the modified on and put the stock one back but when i restarted my phone is was just a black screen after the android guy and it comes up in stock recovery instead of cwm.

This is because you forgot to set the permissions of the new build prop to rw- r-- ---.

Try factory resetting from the stock recovery. Then tell me if it boots or now. It should boot, but it'll freeze when you turn off the screen. Tell me if it boots first and if it does, I'll tell you how to fix the screen problem

This would be easier...

adb shell chmod 644 /system/build.prop

It won't boot at all after the green android guy. And I can't get it to recognize in adb. I honestly don't know what Im going to do.

Boot to ftm and use adb. It is the other vol + power button combo. For example, if vol down + power is cwm, then vol up + power is ftm. I don't have a vital so i am unsure which is which.

 

[Bub95]

Im in FTM now, but I don't understand this adb . I keeps recognizing my device as ?

That's because you are in windows and need to install the zte usb drivers. Pretty straight forward. I pulled the driver install file from the supreme stock rom in case you need it.

I already have them installed and I re-installed just now but still no luck. I keeps showing up as ? devices.
