The 9900 is known for poor battery life and even poorer reception.....sell them and get a 9810.....much better......(just my opinion)....

I realized today I wont sell my 9810. The speeds especially in suburbs is just too awesome. I see people stating 200kbps, I see even 400kbps and higher depending obviously on the server. Best phone ever. It could be maybe your phone is roaming and the network you are roaming on can only let you suck their network juices via EDGE and not 3G. Sounds like a poor reception issue or an OS that has poor and not strong signal lock as far as your network is concerned. Try reload with a different OS older or newer and see.

firstly the 9900 is the best Bis capable blackberry available.

mopac my friend did you do a red blink repair? If you did your NV is probably corrupt and you need to repair it.Download nv writer and download a nv file for your 9900 put phone in FOS and just write the new nv reload os and its fixed

thesayan, I'm clueless what ur talkin about....could u give us a kinda explanation, and a walkthrough?....I don't know about nv and fos.....no joke....

fos is factory operating system it basically allows you to do things on the phone only RIM can and NV is basically the Radio code for the phone that allows it to connect to different frequencies and bandwidths

the FOS loader is just a executable program that you just double click you just connect phone to pc and run the program it loads onto the phone to use NV writer run Blackberry desktop software allow it to open don't press anything minimise it don't close

you should have downloaded NV writer and a NV file for your phone run NV writer check in device manager what port your phone is on select port in NV writer press connect then write NV select the file you downloaded and it will run wait till it stops takes a few min then just reload your normal OS

You are right, its that redblink software that damaged my two phones. Thanks so much, lemme try to download those files you have advised me to download. I will get back to you. Thanks a lot for always lending a helping hand. One love.

Sorry to bother you again. Where can I download those softwares you have told me to download? I only found for Samsung. Please help. Thanks.

FOS for 9900 can be found here http://www.4shared.com/file/JQEr9oAF/FACTORY_OS_BB_9900__FOS500458.html

Thesayen, thanx a lot for your time and effort......my main toys are computers, but one is never too old to learn....last thing, what is red blink repair?....and do I wipe, then those files, Then os?...Thanx again buddy....I might consider 9900 again, but always had signal problems...no probs on my 9810...

Red blink repair is there is a problem with some of the 9900's it does not turn on only the red light keeps blinking. Its the efs that is corrupt repairing that sometimes messes up your imei sometimes but always messes up your NV

its actually a huge flaw because it also allows you to change the imei among other things. Computers are also my toys but had to learn all about blackberry's because of being out of work and needing internet bis is cheaper then adsl or 3G lol

you run the fos executable that installs fos on your phone then you have to open BB desktop software don't press anything minimise it then run nv writer select port that bb is on connect press write nv and select the txt nv file you downloaded then after the program finished install your normal os

fyi the 9810 actually is very similar to the 99000 same chipset and cpu only the casing and so on differ the programs and fixes also work on it you just have to download its FOS and NV file

Does the DFS CDMA Tool require an internet connection to do the job? I can't see anything when I click on Write RF.
