Atom Pure GSM Signal Problem ! Help !

[tianz]

I recently have been given a 2nd hand Atom Pure, but when i insert any valid simcard, the atom won't get a signal.
I don't know if locked or unlocked, but I didn't get any warning like " Invalid Simcard " or something else, the atom just can't get any signal ( tried 3 different simcard from 3 different operator )

Anyone have any idea to repair it ? maybe reflash the Radio part ?

I have simmiliar problem with old Qtek smartphone which can't get off the "Flight Mode", tried reflash it didnot work, sent it to warranty and come back healthy ( the seal did not even teared, so maybe it can be done via software ?? )

I can't send it to warranty, cause my friend give it to me from out of country, and I even didn't know that my atom still in warranty period or not.

Please help, It would be a waste if I can't get the GSM part work again

BTW, the ROM 20060426B1WWE.

Thank you

try to flash the older rom

[tianz]

tried to reflash it again, with another PC new active sync 4.2, still the same problem.

Tried to download official rom update fromm seeo2.com, it says there's no update rom for my atom (based on IMEI number, already preloded with the latest ROM), so I can't find the link to download.

@kropotov

Just reflashed again with official rom (Xda-Atom-ENG-20060426.exe), "Connection Error" Again ! (tried on three different PC)

Is there another way beside reflashing the ROM ?

Thank you

[tianz]

Is there any way that I can update it via Mini SD card ?

Any other way ?? please help :(

I've read above link you gave me, but it seem all the tools must be used in healthy state or at least can enter in to bootloader mode. while mine can't do anything, stuck in update utility screen (tried all button combination known to man)

I found a way to enter in bootloader mode, but when enter bootloader with mini sd inserted (dummy) it says "Start downloading". what I'm asking which way downloading proccess ?? atom to SD or SD to Atom ?

I found WM5 tool for dumping rom, it not specified for certain device. If I enable to dump healthy image rom to SD (from another and the same version rom of Atom), Is there any way that I can flash it to broken atom without in boot loader mode ??

I will keep reading above link you give me, I will be waiting your next suggestion and help.

Thank you so much.

Found a way, use rec + camera + reset button.
In DM mode choose Exit DM, and my Ayom live again !!!!!!

BUT, Can't find any GSM in Wireless Setting, WTF !!!!!!

Tried to reflash it again

[tianz]

reflash it in normal mode, result GSM gone. reflash it second time in bootloader mode, result good, GSM setting come back, but still can't find any signal ?!

Do I get GSM hardware error ?? or something ??

Thank you

there's a Selftest app. in the programs group, should use it to see what result will return after a GSM module test.

[tianz]

Already did, Self test in program menu and in Diagnostic menu. All result OK.

Just can get signal, I can't make Emergency call either.

Opened the Atom, Antena ok, all seems normal.
