So, To 'root' your ZTE KIS (Virgin)/Orange Dublin/ maybe ROAMER 2...
by Installing the required more flexible (ClockWorkMod based) Recovery first...
EDIT: I did a restore of my phones stock backup and completely forgot that it unrooted and brought back the original recovery. BLEH!!! lol
Brief instructions first...
D/l + install Android SDK or whatever is required to use adb.exe/fastboot.exe from the command line
D/l 'recovery-clockwork-4.0.1.5s-roamer2.img' to C:\Program Files (x86)\Android\android-sdk\platform-tools
D/l rooting stuff (
Superuser-3.1.3-arm-signed.zip) from
http://downloads.nos...-arm-signed.zip http://androidsu.com/superuser/
adb reboot bootloader
fastboot devices
fastboot flash recovery C:\recovery-clockwork-4.0.1.5s-roamer2.img
as per instructions from another website regarding a similar model, do the last command a few times
fastboot reboot IMMEDIATELY press VOLUME UP button on your handset
Handset should reboot into the orange recovery screen

, hopefully not the one with blue text
Now use the orange recovery menu...
Backup...
You really SHOULD do a nandroid backup by selecting 'backup and restore' 6th option
then select 'Backup' 1st option, wait a minute or two for backup to complete.
To root...
Select 'install zip from sdcard' 5th option down.
then 'choose zip from sdcard' 1st Option.
now navigate to and select the '
Superuser-3.1.3-arm-signed.zip' file
I have a feeling you have to install the custom ROM a few steps below, in order for the custom recovery to stay put.
Now Detailed instructions for some steps above...
So to clarify for you folks to install the clockwork recovery which you have to do BEFORE rooting...
### Install Android SDK, or whatever you need in order to get 'adb' and 'fastboot' commands working
#1#
###
### Download the recovery image "
recovery-clockwork-4.0.1.5s-roamer2.img" from...
#2# here:
http://android.podtwo.com/recovery/ (bit slow sometimes)
### or:
https://www.dropbox.....5s-roamer2.img
and Download the rooting stuff (
Superuser-3.1.3-arm-signed.zip) from
http://downloads.nos...-arm-signed.zip http://androidsu.com/superuser/
This needs to be placed in the root of the sdcard in your phone
From a command line (Windows for this example)
type whatever you need to change to the folder containing both fastboot.exe and adb.exe ....
cd "C:\Program Files (x86)\Android\android-sdk\platform-tools\"
Now looking like the following...
C:\Program Files (x86)\Android\android-sdk\platform-tools>prompt C:$G
so it will now look tidy like this... you only need to type the 'prompt C:$G' bit in for tidy reasons
C:>
### Then...
#3#
###
C:>adb reboot bootloader
>* daemon not running. starting it now on port 5037 *
>* daemon started successfully *
C:>fastboot devices
>ROAMER2 fastboot
C:>fastboot flash recovery C:\recovery-clockwork-4.0.1.5s-roamer2.img
>sending 'recovery' (8544 KB)...
>OKAY [ 2.139s]
>writing 'recovery'...
>OKAY [ 1.703s]
>finished. total time: 3.851s
### On the computer keyboard press the up arrow or F3 key and do the above command 1 or 2 more times
#4#
###
### Now get ready to press the VOLUME UP button on your handset
#5#
### and enter...
C:>fastboot reboot
Handset should reboot into the orange recovery screen

, hopefully not the one with blue text
I hope to get on to the bit for rooting the device for you soon, if you want it sooner let me know, links are on the sd card in the phone.
I've tried to give a bit more detail in this post since the phone is a low-cost entry-level model and the likely owners will be noobs, or like ME I read the specs and were fooled into thinking they were actually going to get 512mb RAM on a device for under £60! Well it's been a learning curve, in some ways it's easier to root than Samsung, but with Samsung i can do it without ever going near a PC. htc desire S (CDMA) bigger pain.
IMPORTANT: At this point you really should go into the recovery menu and do a backup IMMEDIATELY!
Do not delete as it can prove very useful, buy a high speed 32gb microsd card for around £20.
RESTORE ADVICE: If restoring it will pretty much unroot your device as it did mine, UNLESS you do an ADVANCED RESTORE, and ONLY restore System, Data, Cache, Restoring the Recovery.img is what will overwrite the orange recovery menu, and replace it with the crippled blue recovery that came with the phone.
#####
#End# P.S. And as for Network Unlocking the phone with a subsidy pin or whatever, i've no idea yet.
##### Virgin appears not to be able to get hold of the codes.
AS I DON'T KNOW HOW I DID IT! OTT details for clarity...
### IMPORTANT ###
# be careful where you click when formatting
# do NOT format /sdcard (of course) do Nandroid Backup first too, also consider SMS Backup and Restore (APK) conctacts,
# backups of your other apps in case you can't find later on.

press back
press back
Click reboot system now
NOW FOR THE REBOOT:
Green Android Splash image Loads up, flickers a little bit, then Red LED turns off, stays on a basic android(fancy text) bootanimation for ages
, then it actually boots up fine.

i really hate Virgin/ZTE for making this such a pain compared to other manufacturers, i will think ten times before going with ZTE/Virgin again!!!!!!!!!! i'm even considering cuting off all my virgin services after all this. lol
The mostly useless stock recovery screen output...
