Thanks for the reply bro! I bought my phone on May last year in Malaysia and I'm in the Philippines right now. I think the 1 yr warranty had lapsed.

Can you please teach me how to do a full flash as you have stated. I currently have SETool v1.11 lite, w300i menu.ml, and W300i_R9A036_MAIN_GENERIC_JE_RED49.mbn. all came from download area. I really appreciate you helping me on this. Thanks
