Made a mistake flashed the MF636

[julioac]

I unlocked my Cellcom (Israel) MF636 fine the DC-unlocker. Then I tried to use the modem with ATT here in Puerto Rico, but only detected EDGE and not 3G.

So... I installed a flash from telstra, and now I'm screwed.



This is the info on DC-unlocker:


DC - Unlocker 2 Client 1.00.0291

Detecting card :

selection :
manufacturer - ZTE
model - Auto detect

Found modem : MF636
Model : ZTE MF636
IMEI : 352847024132191
Firmware : M01
SIM Lock status : Unknown (Invalid SIM lock data)

Any sugestions on fixing this?

Thanks.

You mean you have upgrade the wrong firmware?Now what is the status?is it taking the drivers or not?

[julioac]

It takes the drivers, but won't let me use any SIM card. It says the SIM card is invalid.

[Avantha]

You have to upgrade the original firmware again.But no public firmware is available for ZTE.When you detect the modem,did you insert the locked sim?Please insert the locked sim (different operator) and try to detect the modem by DC Unlocker and post the logs.

could you try to use unbranded conenction software? You can download it here: http://www.dc-unlocker.com/downloads/open/46
enter your provider connenction settings and try to connect.

I've tried the software before flashing and the drivers did not detect the MF636. I tried it again, and the same happened.

[Avantha]

You should upgrade the original firmware again.Please give me little time,i will try to get you the original firmware.

[julioac]

Thank you very much!

[julioac]

Did you find anything?

Thanks!

[julioac]

Anything new on this? Anybody with a factory firmware for the ZTE mf636?

Thanks!

Yes, we want a flash solution from DC Unlocker for flashing ZTE Modems.

Any resolution to this?

I too have flashed with the m01 firmware and am getting the invalid sim lock message.

My original fimware was an unlocked Rogers firmware.

Thanks

[JVoorhees]

Is there any way to unlock the m01 firmware?

Is says invalid sim lock data.

I don't really care about flashing it back to the old firmware- just want to unlock it.

Thanks

Can you post the logs here...
