1st method:[/b]
WARNING: Make sure you have at least 50% battery capacity before continue!
1) Extract the ZIP file, rename the .nb0 file to firmware.nb0

The .nb0 is the file extension, if you hide file extension in Windows you don't need to do it. But I suggest you do the second method because the first method is problematic and save you the hassle by not having to rename the file and will ALWAYS work

hmm try to rename the file to firmware.nb0. When in download mode your phone will keep appearing Incoming Download Mode
polling, get oemsbl_mode=1?

Yes. My phone keep appearing:
polling, get oemsbl_mode=1

I also tried to rename the file to firmware.nb0, but the result was same:
The software image file does not match with your phone software... 

The Wellcom file works fine with me......maybe you should try it again since you made it with the CSL ROM.....maybe try downloading the Wellcom file from another source again

Thanks for the advice. Now, I downloading the WellcoM ROM from this URL: http://www.wellcommobile.com/A99_ROM_2_3.rar
Hopefully it will work for me 

OHH hehe actually i saw that you using SUT L1 v1.7.0 and i using SUT L1 v1.7.2. I didnt know that this will cause the problem . Sorry yah, i should have follow my feelings and inform you the differences. At least save you the hussle but on the other hand we get to know what the problem so that can help others with this problem . Lucky you

bro u got a step by step guide on how you backup your phone up to flashing the ROM?

the flashing part I get it la.. just the back up part.. dam blur. online xda all give so many stuff about NAND and downloading more files.. but Najmods just said need to follow instruction on first page.. first page shows more of how to flash the rom but not rly on full backup+recovery (of d apps + data that i want to recover)

sorry im really new to this..

*EDIT: my phone lagging like shit n all I did was replace the recovery.img with the CWM one.. and some auto install adb stuff on my phone x.x

edit latest: replaced the img n still lagging..sigh.im getting the 4-6 sec lag when i click the side lock button on the phone..i suspect its the adb drivers that auto installed. argh..help

arghhh my phone jus resetted even though i was on wellcom rom!! x.x

n some of my dock buttons on my go launcher is lagging..sigh..

mayb root + super charge may solve d prob cuz mebe my phone crash cuz of lack of ram

how long it take times?

Yes I use that SD booster although it doesn't matter which SD booster did you use because all of them do the same thing; changing the cache size.

Rule of thumb, don't instal too much stuff that you don't use. Fewer stuff = more free space and memory. Use Root Explorer to rename/delete stock apps that you don't like such as weather, stock market etc.

@bidiey_afandi,
Thank you. I'm about to follow your advice and will flash via SUT
