Laugh Easiest way to root GT540 running 2.1! Now EVERYONE can root!

Many(along with me) had failed to root their GT540 running 2.1 with the previous One-Click Rooter.. Don't feel down, now we can root too! With just one-click! This one is more simple...

-Enable USB Debugging Mode, Allow Mock Locations & Unknown Sources...
-Download "z4root" from the Market...
-Open the app, click the 'root' button...

You are done! After some seconds the phone will restart on it's own & yay! It's rooted!

***z4root has been removed from Market, check post #12 for apk***

It doesnt work for me. It says USB debugging mode must be activated even though it already is. Pretty frustrating

Try this: Disable USB Debugging Mode, restart, enable USB debugging mode and then try to root again...

Hi Nirob..

Before I try this, can you please let me know what the benifits are if I was to root my phone... I think it will allow me to install apps on my SD card is this correct? and if so it that all I need to do or will I have to download another app to do the SD card install? As you mighjt guess I'm new to this so any info you can give me will be a great help.

Also how do you Enable USB Debugging Mode...

Thanks, ACD1055

Hi! Welcome to the forum!

By rooting, you can remove the bloatware that carriers put inside(Use Titanium Backup, available in the Market), modify your system, replace/remove system apps, change bootanimation etc. Some apps need root access also...

Yes, you need to be rooted & install apps2sd(check here: 1click app2sd now includes 1 click root - Android @ MoDaCo for instructions & solution to problems) to install apps in SD...

To enable USB Debugging Mode, go to Settings>Applications>Developement and tick USB Dubugging Mode, untick to disable...

Don't hasitate to ask for help if you need, we'll try our best to help..

THANKS..

I have just looked at the thread you kindly posted. am I correct in thinking that all software I need is in the zip file to root and app2sd? It looks like I need to make files and change the size of the SD card to FAT32 do I need software of this? your post mentions Titanium Backup whats this?

I only have a 2GB card (it came with the phone) is this ok to root and app2sd?

I tried to download the user guide from the link but I have to register so I'll do that later (in work at the min)

Thanks again

Ok. I have set up my SD card to FAT32 etc following the how to guide and minitool but now I'm stuck..
I've downloaded the autoroot app2sd file and double clicked the batch file selected 2 for english and them there is a big list;

r. root the phone
u. unroot the phone
1 standard app2sd data
2 standard app2sd cache
3 standard app2sd appdata
4 full app2sd
5 remove
6 quite and restart the phone
7 back to language
8 check app2sdapp2sd
9 exit

which do I pick, I want to root and start saving to my sd card. so is it R to root?? and then 4 for the app2sd???

once I have done this should I see a new app on my phone so i know it's worked?

I recommend z4root to root GT540, i saw some guys having trouble rooting with the "r" option... After you have rooted, 4 for installing apps2sd & then 6 to restart your phone... if it installed correctly you'll see the option "Apps2SD" in Settings>Applications

Keep in mind that you can't remove your SD card after installing apps2sd.. if you remove it, or error occurs related to SD card, then you are screwed...

Where can I find z4root, do you know? I did try to click on the file you attached but it said no application found and I have searched the market place without luck.

Do I need to root my phone to run app2sd? Iím still unsure if I need to root my phone as if I can save to SD then I think I should be fine.. What are the main benefits of rooting the phone?

Once it's installed will it automatically work without me having to do anything?

Thank you again

I think androidforums.com is having problems... i was starting a thread, tried to upload an apk but failed 3times... Google removed z4root from the market.. sorry, i don't know where you can download z4root.. i installed it when it was in Market, and the apk i uploaded is from my system...

Yes, you have to root your device to install apps2sd... you can't install apps2sd if you are not rooted...

I mentioned above what you can do when you are rooted... It's gives you full access to your system... You can modify you system, remove carrier crapwares, remove system apps, replace system apps with newer versions etc.. Apps like Root Explorer, Titanium Backup, Apps2SD requires root...

I think you'll need to tick the "Apps2SD" options in Settings>Applications... if it's ticked then don't need to do anything...

Cheers for the reply.

I guess I'll have to search for z4root and install this then.

I have done a google search and it returns hits but I'm always a little worried about downloading from unknown sites.

I can’t find z4root anywhere, well anywhere I think it’s safe to download from so I think I’ll try the option for rooting above by selecting R in the auotroot app2sd file .. How will I know if my phone has been rooted, will a new app show anywhere or do I need to download another app afterwords to explore and control my phone, if so which app should I download?

When you say once it’s been done don’t remove your SD card or your screwed.. what will happen will I break my phone or the SD card? if I wanted to remove the sd card for any reason would just need ot unroot the phone and then it would be safe?

All done and rooted now so managed to get rid of lot of bloatware and apps i dont need, used titanium backup to do it which is simple enough. Just wondering what else i can now do as i cant seem to find how to change boot screen and other little bits like that, do i need more root apps to mess with it more?


Thanks for help again nirod

As you have the Superuser icon, you are now rooted... Sorry I can't help with apps2sd anyfurther as I didn't do it... try reading that thread to the end and if you can't find a solution try asking them... What i know is if you have installed the Modem Driver in your PC, the tools can't connect with the phone... and about the SD card, you can remove it while your phone is turned off.. But, if you turn on while the SD card is removed your phone will crash, as apps2sd adds the part of the sd as phone memory...

To change your bootanimation, you need an app called Bootanimation Changer.. with the free version their are some bootanimation that you can select.. and with the Paid version you can select your own bootanimation(Availble in many websites)... I replaced the YouTube app with newer version... i also replaced the 3D Gallery with the old 2D Gallery which i think is better...(I updated the Market also, but it doesn't need root or apps)

**EDIT: Check here how to change Boot Animation easily: Change your Boot Animation! :D

Temporary root means your phone will unroot when your device is restarted... So, I recommend that you use permanent root, as you can unroot anytime you want using z4root...

You used the default browser to download?? Then it'll say that... Just ignore it and finish the download.... Open your favourite file manager & go to sdcard, find it and install...

I have down loaded the z4root apk from your upload to my laptop. do i have to transfer the file onto the sd card of the phone and run from there?

Move to SD & install it with your File Manager...

Don't worry, feel free to ask

I will write a totally different view about this phone called LG OPTIMUS GT540. According to me, why should I experiment with my phone in such a way? Why not the company itself does that for us? Why should we take such risks where anyone who is not a tech savvy, like me, should carry on such experiments with this phone of 11,000.00 INR? After purchasing the phone why should we take such pain? It seems worse when it is reported that if you make a mistake, the phone will be severely damaged!!!! My nokia phones like nokia 5200, nokia 7710, nokia x3 which run on symbian OS are much better where you can easily view the microsd and can copy whatever you wish to it without that nagging ROOT, UNLOCK, TITANIUM BACKUP, CHINESE STUFF, ROOT EXPLORER, etc...etc....At times, I feel disgusted with this device.

As a example, This is the reason why Windows has tons of virus where linux has a little few...

Root isn't a serious thing... Google is already eager to supply users pre-rooted Android device but carriers & manufacturers don't want that... Root can leave the OS in risk if the user don't be careful or don't know about Android... And, if the user is a noob, they will keep bricking the device trying new interesting thing... Viruses effect Symbian OS & Android has no virus... As you can play with Android, you can't play with the other OSes... These modifying process are critical, but can you think these in other OSes? Nope, you can't...

If you are disgusted about Android, never touch an iPhone/iPad/iPod Touch...

It worked! No idea why as I spent all morning installing and trying out various versions of z4root and got stuck at the USB debugging request. Thank you!

Please don't make multiple posts... We'll try to help if we can... One post is enough... Multiple post will make others confused + it makes the thread bigger... Thanks..

Don't uninstall Latitude & Talk...

To remove Facebook for LG & Twitter for LG just uninstall ''SNS''...

You can share your realtime location via Latitude with you friends, it's a part of Google Maps...
