[Android Q&A, Help & Troubleshooting] ammarabbasi:
Good day everyone,

I hope you all are doing well :D

It's been almost a year since I bought Ideos U8150-B but to tell you the truth I wasn't satisfied with the phone's speed, it used to lag alot. I tried different methods to fix it but they weren't quite successful.

Then I came to know through the XDA forums about rooting, installing a custom rom etc. I felt quite relieved but being a noob I couldn't do much :D

Luckily I now have found the way of doing this the easy way, Just follow the intructions below:

NOTE: Rooting/Modifying your ROM/Installing a new ROM will void your warranty and at times it can be risky too, you may end up bricking your phone. DO THIS ONLY WHEN YOU ARE MENTALLY PREPARED OR WHEN YOU KNOW WHAT YOU ARE DOING

ROOTING Your Android

There are many ways available on the internet about how to root your android but they unluckily didn't work for me much. While browsing through different threads I came to know about this awesome software "z4root" which can root your phone with just one click and luckily it did the job quite well, that settles that :)

Now How to Install a Custom ROM:

Follow these steps:

1- You need to flash a custom recovery

In my case I flashed ClockworkMod 3.0.2.4 (by marcnvidic), there are some others available too but I don't quite know about them much so I would recommend clockworkmod.

HOW TO flash?

It's simple, install "Root toolbox", it must be available in the android market if not then google it.

Install it on your android and when you will open it you will see a number of options, just look for "Flash Recovery" option and then it will ask you to browse the recovery, navigate it to where you placed the recovery file and it will flash it for you within seconds.

2- Choose a custom ROM: Download the custom ROM of your choice and place it in the sd card. I am currently using Fusionideos and I found it to be the best ROM for ideos U8150. There are many others available as well.

3- After downloading and placing your ROM in the sd card switch off your phone and boot it in recovery mode (To boot in recovery mode press volume up key+call key/send key+power button for about 5 seconds and it will boot your phone into recovery mode and you will see a black screen with few options like wipe data, wipe cache, install zip from sd card etc. If you don't then you must have made some mistake while flashing the recovery, if that happens try step #1 again.

4- Once you have booted your phone in recovery mode you can finally start installing a custom ROM, just do the following:

* Perform a backup of your current ROM using Backup and restore option in the recovery.

* After backup is complete go to the main screen and select Wipe data/factory reset.

* After that return to the main screen and finally select "install .zip from sd card"

It will take you to browse the custom ROM file, just navigate it to where you placed it. Wait for the installation to complete. After the installation is complete reboot your phone via the reboot option on the main screen and hopefully you will have your new custom ROM running :)

I hope that was helpful and you won't have to spend hours browsing the web to learn about all this :)
