iPhone bought in Thailand, no signal

[Shimfs]

Hi guys
I have been asked to help a friend, to fix his iphone 3G.
The iPhone is bought in Thailand, and it worked fine, up untill the point where he tried to sync it with itunes. Afterwards, it has refused to gain any signal whatsoever.

I have checked the serial number on Apples website, to ensure it isn't a mock up, however, on the lock screen, under the clock, the language is some chinese stuff, while the rest of the phone is danish.

Do you guys think it needs to be unlocked? jailbroken, synced again or what?

Phone probably locked to carrier? Do you guys just buy stuff w/o checking into whats what...

I have had nothing to do with the iphone, i didn't even know about it, untill he had the problem.

The problem is, when he received it, he inserted his own SIM card, and it worked fine, signal and all.
After the sync, it has stopped working, he can insert the card, write the code, and the bar that tells how strong the signal is, stays at 1, without writing his carrier name.

the phone probably is software unlocked. When he first received the phone, it worked fine, he then hook it up to itunes and somehow restore it to the latest firmware and therefore, the unlocked is gone.

so i have to jailbreak it with green poison? and then use ultra snow to get it to 4.2.1?

i don't have the time, to wait for a 4.3 unlock

Greenpois0n will not work for 3G. Before you do any thing, can you find out the following info for me?

1. What is the firmware version on the phone?
2. What is the baseband version on the phone?

Go to setting/general/about and you can find these info.

 

[jdaniel]

yeah check your firmware and baseband and google for guides

He probably went and reset the phone and if it was software unlock then he un-did it... hopefully he didnt update the software and baseband to one that you cannot unlock... I am not sure about 3G phones.

 

[Shimfs]

it had baseband 05.15.04, which usually cannot be unlocked, unless you update it to 6.xxxx which is an ipad baseband.
The negative side is, i can never revert the change...

i have just jailbroken it, and i am about to unlock it. I have one question though.
Even though i only enable the danish keyboard. It still uses Thai for some text -.- on the lock screen (the date) and standard keybaord
i wonder how i change that.

 

[Crystal-RX]

There are 2 sections in the setting that you need to change; Keyboard & International. Did you change both?

 

[Shimfs]

oh i forgot the international bit.
Most of the iphone is in danish, its only those two things i mentioned.
but atm i got some troubles, i forgot to check deactivate (so i can use SAM)
so i am jailbreaking it again (without updating the baseband again) but at the moment it is stuck at downloading jailbreak data to the phone

 

[Crystal-RX]

redo jailbreaking again should work. Are you using Redsn0w 0.9.6B6?

 

[Shimfs]

i redid it, its installing the bundles now,

im using 0.9.6RC8

 

[Shimfs]

i cant get it to work
i asked redsnow to deactivate the phone, but the phone still works as usual. And when i insert a SIM card, i get 1 tiny bar and no carrier name = no signal.

when i open SAM, i can chose hacktivate (its off by default) if i change that, it asks me to revert it to lockdown, which it says i have to do under utillities. When i do that, it said it was successfull. Then i go back to hacktivate, and it asks me to repeat it -.-

 

[Shimfs]

ahh its factory activated.. need to know how to disable that
