and I apologize if the topic is open, only speak very little English and I hope you understand that I am not the subject makes it easy to find. I have a problem and I hope that someone out here help me if I had something similar and has been fixed. I'm from Venezuela, acquired in my MB200 dext version, with the 5025 radio release and the release although I spoke to upload this rom to flash "mamba 2.0.Psupermonster morrison tmo customer" is Russian. I did was change my cliq MB200 in the baseband left him in 5036 though it was the operator I wanted to use that uses the 5025, release him and stay in 5036 but had some problems when the phone signal lasted a little idle. he lost all signal. for example at night while sleeping, lost all the baseband signal. clarified that since I solved this problem, I have the 5025 baseband back down the signal problem and can once again told me the 3g rom could not recover. Now what I want is simple, after much searching and not found anything to help me only this: the operator that sold me the phone is of 850 MHz but as it is very bad, release the phone to use it in a better working at 900MHz . and what is found that of the baseband 850 is 5025 and that of 900 is 5036. my concern now, someone could help me with certainty whether flashing the radio until 5036 could have 3g on 900mHz ?? only the baseband or would have to install a new rom that has the baseband native 5036
