[iPAQ rw6828, XDA Atom General] sirrus_linux:
I have an O2 Atom with the following specs:

ROM 20080612B6WWE

EXTROM EX0503

RADIO R060822N_MN1ARC_RS00052

currently running on PDAVIET rom from Sonblack.

My problem is as follows:

1. when i boot up the pda everything goes smoothly except there is a network unavailable message in my home menu and a stupid "no network !" sign at the signal strength meter.

2. interestingly the green LED flashes every few seconds as if logged onto a network provider.

3. more interestingly the green LED flashes every few seconds as if logged onto a network provider even if i remove the SIM card and boot into the OS.

My previous configuration which used to work:

Original ROM from O2 Asia dependent on Windows Mobile 5.1

EXTROM EX0480

RADIO R060822N_MN1ARC_RS00049

Things I have tried to make her work:

1. Tested GSM module --> IMEI OK --> PASS

2. Tested Wifi module ---> PASS --> surfed internet using wifi --> OK

3. Tested Bluetooth module --> PASS --> sent files to another PDA --> OK

4. Tested FM radio module --> PASS --> FM radio working

5. Tested ROM checksum --> PASS

6. Flashed a dozen times using different roms and radio versions eg:

radio versions RADIO R060822N_MN1ARC_RS00052

RADIO R060822N_MN1ARC_RS00049

RADIO R060822N_MN1ARC_RS00048

RADIO R060822N_MN1ARC_RS00038

got these different roms from O2 atom wiki -- keep up the good job guys.

7. finally flashed from the latest O2 Asia provided rom --> USELESS

My theories:

1. There is no possible hardware issue with the internal antennae as i think even the wifi module shares the same antennae and wifi is working like a charm

2. There is no possiblity of a faulty SIM cause i have checked with a dozen different SIMS all of them give a no network error.

3. There is no possibilty of a Hardware error at the SIM contacts cause i can use SIM manager on all SIMS flawlessly and access contacts and sim info on all the dozen SIMS that i tested.

4. I have tested more than six SIMS in manual mode for different bands GSM 900, GSM 1800, GSM 1900 combination and auto mode ---> USELESS.

Extra Information:

1. GPRS is unable to connect --> gives some dailing error.

2. I cannot scan for available networks using manual mode -->

it shows me a scanning for all available networks dialog and then an

empty list is shown where i can select nothing.

3. I cannot scan for available networks using auto mode -->

it shows me a registering on network dialog and then a cannot register on

a selected network error.

4. All of the other SIMS are from different Network providers and are function

well in my other Nokia, Atom life phones.

I am at my wits end <----- to tell you the truth this is the fourth week i have been trying for a solution before posting all the details here.

Please share you theories, ideas, experiences with me on this thread so that other souls might be spared the mental torture of the O2 service centre and their bizzare claims.

Hoping for a solution <------ help me out

PS: Thank You for reading my post ..... your levels of Patience are increasing.

PS: I remember dropping my Atom off a height of 15ft due to which the side

bluetooth tranciever plastic cover came off ....... but hey the atom was

working after that. The real problem started after i flashed the O2 Asia

provided ROM with a some stupid localization update.

PS: Peace !
