T mobile Pulse Mini (U8110) Rooting and Tooting

I've had mine a while now and for the money I paid for it, it's a cracking little phone.
I got my hands on a spare identical phone so thought I would look at making a little more room on it etc as it runs 2.1 and apps are installed into the phone memory so even though you have a 2gb Micro SD card you can't use it for much other than music.

I also wanted to put a boot loader on so I could then try some different roms.

After a week of trawling through countless guides with bits of info here and there I found a very quick and simple way to root the phone, so simple I tried the steps straight away on the one I use every day and its working great.

Obviously if you mess your phone up following any of this info then it's your own fault, these notes are just what I did and i've done it now on 2 phones without any issues.

Get hold of z4root.1.3.0.apk and copy it into the SD card in the root i.e just drop it into the main card area. The ZIP file for z4root is at the bottom of the first post on this page.
Install Astra File manager from the Market.
Once installed, (from the home screen) press Menu and Settings, scroll down to Applications and go in there.
Make sure Unknown sources is ticked.
Also look in Development and tick USB Debugging (you need that in a bit)

Open Astro, you will see the z4root file and select Open App Manager, z4root will now install.

If you can't see your SD card check if your card is still mounted for USB data transfer.

Once installed, launch z4root, select the option for permanent root.
It will warn you if you forgot to turn on developer mode.
Z4 will take about 5 minutes so don't be tempted to mess about with the phone, just wait and it will then offer to reboot.


Once rebooted your now rooted and can use SU mode etc.


Total time, about 10 minutes.
One thing I did was install link2sd which cured my issues, I can move almost every app to SD and it works by creating symbolic links to the application so the phone thinks they are still in the local memory, i've now got plenty of internal storage and may not bother flashing to 2.2/2.3.


AMONRA RECOVERY
I wanted to put this on, mainly so I could take a full NAND backup.
There are lots and lots of posts to install adb etc but this is a little time consuming, to do it the way I've listed here takes no more than 5 mins.

Download Amonra 1.6.2 and extract it to a folder.
I use linux so for me the process was very simple.

open a terminal and move into the folder, in my case I called the folder amonra and it was in my desktop.
so I did (remember linux is case sensitive)

cd Desktop
cd amonra
chmod +x install-recovery-linux.sh

now put the phone in bootloader mode, hold RED, Vol - and POWER for about 5 seconds it should sit at the T-mobile screen.

type
./install-recovery-linux.sh

the ./ is important in linux it means "here" i.e this directory.
The chmod +x means "give this file permission to run (eXecute)"
You don't need sudo or su permissions as the file is in your home directories so you own it.
You should see a message the boot loader is being sent and then complete.
The whole process only takes 3 or 4 seconds.

You can power cycle at this point.
If you want to test recovery mode, remove the battery to power right down.
Give the phone 10 seconds to discharge.
Insert battery
Hold GREEN, Vol + and PWR for about 5 seconds, you should see this.

It's just a case now of selecting Backup/Restore and then NAND backup to make a total copy of your current firmware and phone status (well worth doing).


Once this is done you have a folder in your SD called NANDROID, you can copy this to your PC for safe keeping.
The backup is in the form of a date and time stamp.

I've tried some roms and had plenty sit there refusing to work, recovery by NAND restore has worked 100% bringing the phone back to where I was before.

I hope this guide helps anyone having the T-mobile pulse mini who wants to root it easily and put AmonRa on without too much messing about.
Apart from the Z4 screenshot all the ones above were taken on my phone live so you can see they do work.

Apart from using the pc to transfer the z4root file and the AmonRa file you don't need a pc for any other parts.

For info I have tried clockwork mod but I'm having some fun and games with the boot loader so I might try again - rom manager was very difficult to get on due to the market advising this phone is not compatible.
This is why I went to try AmonRa method which saved a lot of time.
