MF627 Diagnostic port not found.

[v8hoon]

Hello,
I was wondering if someone could help me out. Im having problems getting the diagnostic port to show on my ZTE MF627. When i auto detect i get the error "Diagnostic port not found !" When i go into device manager i can only see 1 device related to the modem "ZTE NMEA Device (COM3)", i assume thats the application port. Ive uninstalled/reinstalled drivers, ive tried manually entering the ports from which i can detect the modem correctly but i receive an error code 36. when i attempt to unlock.
Cheers,
Ed.

I have managed to get the ports to show in device manager. Application interface 1,2,3 + Diagnostic is showing. But when i attempt to unlock i get error message 21.

Please insert the sim card in to the modem (locked sim card),then DC Unlocker will detect the modem.after that you can unlock it without any problem.

Avantha.

[v8hoon]

This is with a locked sim, The MF627 Is locked to Three AU and im using a Vodafone simcard during detection.

[Avantha]

Please post the log here.....

[Avantha]

For correct ZTE modem detection, please plug modem with invalid operator SIM inserted. Wait till software starts the modem, close ZTE software and then you can detect modem with DC-Unlocker.You should check, if the drivers are installeed and if you see the modem in device manager.

BR,
Avantha.

With Auto detect i get:


DC - Unlocker 2 Client 1.00.0267

Detecting card :

selection :
manufacturer - ZTE
model - Auto detect

Diagnostic port not found !

With manual i get:

DC - Unlocker 2 Client 1.00.0267

Detecting card :

selection :
manufacturer - ZTE
model - ZTE MF627
application port - COM5
diagnostic port - COM6

Found modem : MF627
Model : ZTE MF627
IMEI : XXXXXXXXXXXXXXX
Firmware : BD_3GHAP673A4V1.0.0B05
SIM Lock status : Locked (Card Lock)

But The Diagnostic port still isnt showing in Device manager, but COM6 shows up in the client after i have inserted the stick. Thats where i think the problem is. (There are no other COM ports available)

COM5 shows as "ZTE NMEA Device (COM5) in device manager.

When i try to unlock with these settings i get:

Unlocking, please wait ...

unlock failed !

(error code 21)

[Avantha]

I think problem is ZTE drivers,not the DC Unlocker.did you check the device manager?it should detect com and modem.without that you cannot unlock.

[v8hoon]

Yep thats what ive been doing. Insert stick with invalid operator SIM card, Software loads, comes up with "this device is Networked locked contact your service provider & it has a prompt to enter the unlock code. I cancel and close the software then attempt to detect in the client. The stick shows up as "ZTE Propriety USB Modem" It passes diagnostics and in ports it shows "ZTE NMEA Device (COM5)"

[Avantha]

ok,did you see the both com and modem ports in the device manager?are you Dc Unlocker dongle user?

[Arunas]

Here is problem with drivers, please update drivers to generic. You cn get it from not customized manager http://www.dc-unlocker.com/downloads/open/46 or from dc unlocker installer. To detect you must see diagnostic port in device manager.

[v8hoon]

I just uninstalled the Three branded drivers & installed the generic ones. I can get the modem to function normally with correct sim but i still cannot get it to detect properly in the client (valid or invalid sim). Nothing changed with the generic drivers.

[v8hoon]

Im also not a Dc Unlocker dongle user. But have 15 credits.

[Arunas]

to connect internet software access to internet by other port, diagnostic port used for firmware upgrade, unlock and other functions. Maybe you can try other PC ?

[v8hoon]

No luck,
I have tried 2 other PC's with the unbranded drivers & im getting the same results. Diagnostic port not found. I have even tried using yet another simcard (DODO), which i think is Optus based. Is it possible that Three AU has modified the modem to make it harder to utilize the diagnostic port?

[Vincentas]

Could you try to detect the modem on other pc? Are you sure that you close the connection software before detecting modem?

[v8hoon]

Yep the modem is detected everything works besides no diagnostic port. Yes i close the software before detecting on the client. It finds the modem but no diagnostic port.

[Vincentas]

Could you try to use other computer?

[v8hoon]

I have tried 3 computers with identical results and 3 different sim cards with no change.

[Vincentas]

Sorry, but I think we are not able to help you. Could you write me a private message with your username and I will do a refund.

Could you try to detect modem usind autodetect function in dc unlocker? Select your modem manufacturer and model leave autodetect.
Check in device manager, if you see modem dignostic port there (in ports sections). If you can not find it, try updating the drivers. If updating the drivers does not help, could you try other computer?

[Arunas]

Error 21 is canot access to diagnostic port, probably if you select ports manually -- diagnostic port number is wrong or not exits. You can try update drivers pc, and etc, but if no diagnostic port is device manager we cant unlock this modem.
Please use only autodetect model and porst, if you see "diagnostic port not found" please dont buy credits or ask for refund.

We will receive modem with no diagnostic port after ~10 days i will try check what real problem.

[ciccioriccio]

Dear Arunas, when i used autodect mode the dc unlock reply with:
diagnostic port no found.

In device manager the modem in device manager is called ZTE Proprietary USB Modem and work properly on COM 21, wen i asked the modem by diagnostic tab, it respond properly, on device manager on port COM and LPT it looked on ZTE NMEA Device and work on COM 20.

Wen i try on manual detect appears the error code 21.
Understand my problem?
It's the same problem on 3 diferent PC!
Thanks!

[ciccioriccio]

Dear support today i tried to unlock by another 2 PC.
Appears the some error: diagnostic port not found whit autodetect mode..
Help me please

[ciccioriccio]

Dear support today i tried to unlock by another 2 PC.One PC now formatted!
I installed proprlely the driver of dongle.
On device manager the modem is detected as:ZTE Propietary USB Modem on COM 4, in diagnostic tab when i asked the modem it answer properly, on device manager on COM 5 i find ZTE NMEA Device.
Onboard dongle i put locked sim card, before start dc unlocker i started the connection manager software, then stop connection manager and start dc unlocker in autodetect mode appears the some error: diagnostic port not found



Help me please

[ciccioriccio]

Dear support, findend on the web i find this document:

http://www.zte.com.au/downloads/MF332_Compatibility_Guide_V1.1.pdf

It's possible that dc unlocker is incompatible with this dongle becouse the firmware of this dongle not find on windows the diagnostic interface?

[Arunas]

Follow your PDF, you can see diagnostic port must be in device manager. NMEA is not diagnostic and please not use it. Again, i will receive this modem and ill check. No diagnostic port, no unlock !

[fxvxca]

hi do you have by chance any news on the modems without diagnostic port?

is it possible that zte had a different hardware version mounted, so the upgrading process will be different?

(i also tried the free version downgrading the software with the globe flasher) and it doesn't work due to the same problem.... it looks for the diagnostic port.

[fxvxca]

i've just dismounted my card may be this can be helpful for you

near the external antenna connector the numbers written are 1298mr 94vd 1609 (03)

[ciccioriccio]

Great idea and great help.I hope that DC UNLOCKER technicians are does at solving this problem.

I hope that Italian 3 dongle hawe different firmware that does not recognize the diagnostic port.
Studied DC UNLOCKER technichian!!

[fxvxca]

Dc-unlocker does not have solution for this problem. You can not unlock such modem with dc-unlocker.
If you bought credits, write me private message with your username for refund.
