How to's

This section describes many different things you can do to improve your ZT-180

Flashing firmware

Flash from OTG USB with burntool

The Omen created a YouTube video describing - Flashing ZT-180 (0804 ROM with burntool v7.2)

  1. Where to download burntool 7.2 (for the 1030 ROM or earlier) - Download Burntool 7.2
  2. Installing the ZT-180 USB Driver (Windows XP 32 bit)
  3. Downloading firmware
  4. Setting up burntool
  5. Flashing the ZT-180 with the downloaded firmware

For using burntool v7.41 - (password for setting is zenithink)

  1. Where to download burntool v7.41 (for the 1104 ROM or later) - Download Burntool 7.41
  2. The files should linked as follows with a check in the box and the full path of the file and filename listed (use brower button to link your file) and save your settings. Make sure WinCE is unchecked.
 Burntool Settings 
 uboot-spl - ZT_Bx.spl ** 
 uboot-img - ZT_Bx.boot 
 linux-kernel - zImage 
 linux-sys - system.pack.img 
 linux-udat - userdata.pack.img 
 Memory Options - scrub (also checked) for a clean install

** (only to be used if you are flashing from the 1030 ROM or older, and error while flashing the spl can brick the device, make sure the tablet is fully charged and plugged into the power cord, and do not interrupt the process, just follow the prompts on your screen when flashing, DO NOT put the ZT_Bx.spl file in your /sdcard/zt-update folder, flashing spl from sdcard can brick the device)

Attach your tablet via the OTG USB while it's off, turn it on in flashmode (hold round button in front and then the power button and hold for 3-5 seconds), if you installed the secbulk drivers, Device10 will turn green and you can click start to flash the tablet, if you haven't and you are on a 32 bit windows computer, it should prompt you to install the drivers for the SEC SOC Test Board (what the computer recognizes the tablet as in flashmode), install the secbulk drivers, and for good measure, turn the tablet back off and then go back into flashmode and as soon as device10 turns green in burntool, then press start. The flashing should commence.

Flash from SD card

Works with any ZT-180 tablet that has the 1204 ROM or later installed already.

For ROMs before 0415
  1. Create directory named zt-update on root directory of your SD card
  2. copy zImage, system.pack.img and userdata.pack.img files in zt-update directory
  3. insert SD card into ZT-180
  4. turn on ZT-180 while pressing "Menu" button (button on top of ZT-180 that looks like volume down). You can also turn on ZT-180 and press "Menu" when it shows "Press ENTER/MENU to update"
  5. rest is automatic

If you want to flash only kernel, just copy zImage file in zt-update directory. Same for other parts.

For 0415 ROM and later
  1. Same as above - except files should include the following:
  • clear_data_part - *If you want the data partition cleared, if you don't, don't include/create this 0 byte command/file.
  • - (Android System Image)
  • zImage - (USB Mass Storage Kernel)
  • zImage_adb - (ADB Kernel)
  • zImage_update - You need to use the one from update folder first to create the sdcard.img, then you can use the one from usr folder.
  • ZT_Bx.boot


There are two easy ways to root the ZT-180

Universal Androot App

The easiest way to root -

  1. Visit this SITE and download the latest version of Universal Androot
  2. Copy the Universal Androot APK file to a micro SD card on your PC
  3. Remove the micro SD card from your PC
  4. Insert the micro SD card into your ZT-180
  5. Use a file browser to locate the Universal Androot APK file on the micro SD card
  6. Install the Universal Androot App
  7. Run the Universal Androot App


Goto's TxPower Fix & Easy root page and follow the directions listed there.

Note: When rooting Froyo, choose the Do not install Superuser option, then Root (you may need to do this twice). Do not install the SuperUser app afterwards or update the su binary (it will unroot you). Permissions should be given automatically without the SuperUser app if rooted properly with UniversalandRoot 1.6.1.

Using ADB and SDK

This site explains another way to root - Rooting using ADB

Copy files to internal device storage or SD Card

This thread describes how to copy files from a PC to the internal storage partition (/nand) of ~1.3GB of storage space or SD Card - Copy files to /nand or SD Card

Installing Flash

This thread has information on getting flash to work - Flash Lite working on ZT-180

Or if you are running a Froyo ROM, you can download and install this Adobe Flash Player 10.1 app - flash_player.apk


This thread has information on using swap on the ZT-180 - Swap on ZT-180

To find out what swap is read this Swap Definition

tsukaza's method to allow the swap to come on early and let the system load apps with the swap active. These are the steps:

1. open terminal

2. su

3. dd if=/dev/zero of=/mnt/sdcard/external-sdcard/swapfile.swp bs=1024 count=65536

use 1024 x size ( 1024 x 64 = 65536 ). this will initialize the file.

4. busybox mkswap /mnt/sdcard/external-sdcard/swapfile.swp

Turn the file into a swapfile

5. busybox swapon /mnt/sdcard/external-sdcard/swapfile.swp

Turn on the swap space

6. busybox free

This will show you the system memory status

7. Now you need a package named "autostart.apk" not "autostarts.apk"

8. Create a file /data/opt/ containing this -->


/system/bin/busybox swapon /mnt/sdcard/external-sdcard/swapfile.swp


9. chmod 777 /data/opt/

10. reboot

11. open terminal

12. su

13. busybox free

Good luck

Getting Android ID from Emulator

This video is a supplement to the "Fix Market For Slates" Wiki

Google Market

If you flash your software to version 101013 or later, Market should be fully functioning. If you have created an Android ID on your phone or through the Emulator all you will have to do is to log into Market on the ZT-180 with your Google Account credentials.

If you prefer to run a previous version of firmware, there are several ways to get Market working also.


There are a few methods for getting Google Market working

Several require RPM's Script so download it here - RPMScript 1.2

Christian Buchner's System Image

Christian has created a new system image for 0929. You can watch how-to video for flashing market and flash it the same way as 0827 but use the 0929 ZT and Christian's ROMs instead of the 0827 ROMs.

More information can be found here -

Christian Buchner's System Image

omarahum's way
  • This method worked for me

This post by omarahum explains another way to get Google Market working - omarahum's market procedure

Tsukaza's Way

This post from tsukaza explains how he got it to work - tsukasa's market procedure

Christian Buchner's second way

Christian Buchner has this to say -

the 0926 and 0929 firmware images have some library permissions set too strictly such that some Google Apps will fail (no market downloads, process crashes)

these adb commands fix it (copied straight from RPMscript by the way, they can be issued through OTG cable safely)

  • adb remount
  • adb shell chmod 777 /system/build.prop /system/app/* /system/lib/* /system/framework/* /system/etc/permissions/*
  • adb shell chown system.system /system/build.prop /system/app/* /system/lib/* /system/framework/* /system/etc/permissions/*

and then -

Someone pointed out to me that one also needs to push ContactsProvider.apk and Contacts.apk to /system/app to avoid the crashes.

For some unknown reason Zenithink omitted these from their release.


There are three different ways to install Google Market on version 100827

Christian Buchner's System Image

The Omen created a video located here - Market with 100827

This link describes Christian Buchner's system image Christian Buchner's Post

Once you've downloaded the system image file, open burntool settings and browse to it under the choice for "system" and flash like normal.

Then, in a DOS window type:

adb shell sqlite3 /data/data/ "update meta set intvalue='YOUR_ANDROID_ID_HERE' where name='androidId';"

Click the link below for an example -

RPM's Script

RPM's Post on XDA describing his script -

  • Note - Market would not work until the date was set correctly
  • Note - Didn't need to run Market Enabler with the new system.img file
  • Note - I also got the server error but I was finally able to connect and download after waiting awhile.

How to make Market show more Apps

SDcard not being recognized when tablet is fully booted

  • Q: I'm using a current ROM (20110415 or later) and my sdcard suddenly stopped working/being recognized by the tablet. How can I fix that?
  • A: Please read the following post Problems with external SDcard. Pretty much, only have the zImage_update (from update_yaffs folder) in your zt-update folder and flash as usual so the tablet can rebuild the sdcard.img that may have gotten corrupted. It may take a while, but it should reboot after it's finished automatically, do not interupt the process, allow it to complete and reboot on it's own.

SDcard not being recognized when trying to flash a ROM

  • Q: I'm trying to flash a ROM onto the tablet via the sdcard method, but it keeps saying that there is no zImage_update file found, even though I know I put it in the zt-update folder. How can I fix that?
  • A: Most likely, it's the way the sdcard was formatted that is causing it not to be read correctly by the tablet. Please read the following post Herkfrog's suggestion on formatting the sdcard prior to flashing.
