Guys I had the same problem with the k599 Sciphone and none of the solutions found on the internet helped me. New chinese models tend to restart after testing is over and this results in turning the wifi application on. So I spent many hours on thinking how to bypass this function and this morning I woke up with an idea that really worked!! The steps are quite similar with the ones followed to debug older models:

put 2 chips on cell
Disable WLAN.
1-enter in factory mode *#3646633#
2-go to RF Test Tool
3-choose GSM, confirm OK!
4-go to Power scan
5-Select Band DCS1800 click OK
6-the cell frozen
7-wait for 3 minutes testing
8-while testing connect to a pc using the USB cable (do NOT select ANY of the options appearing on the cell screen)
9-Click the CENTER button of the cell until you go back to principal menu
10-go to settings/network settings and choose GSM Preferred or any other option (except WLAN only!!)

In this way the cell does not reboot, and the wifi application stays off, so the option can now be changed...

Hope this helps!

Blackberry w9700 dual sim. it says "not allowed to dial." how fix this? :(


You should be able to reset your phone by taking the following steps:


kb-article-odyssey-unlock-instructions-11-14-09-step1.jpg
Turn on your phone, and go to the dial screen by pressing the GREEN phone icon.

kb-article-odyssey-unlock-instructions-11-14-09-step2.jpg
In the dialing screen type the figures *#3646633#

kb-article-odyssey-unlock-instructions-11-14-09-step3.jpg
The phone should go into engineer mode. Scroll to RF (radio frequency) test tool, this is the 10th option and will be in the second screen.

kb-article-odyssey-unlock-instructions-11-14-09-step4.jpg
Select the RF(radio frequency) test tool option and then select the GSM option.

kb-article-odyssey-unlock-instructions-11-14-09-step5.jpg
When a message appears hit ok to verify.

kb-article-odyssey-unlock-instructions-11-14-09-step6.jpg

kb-article-odyssey-unlock-instructions-11-14-09-step7.jpg
Go to the power scan option then select the band option. Click on the right arrow till you see DCS 1800 . Press OK.

The phone should enter into scan mode, wait a few minutes until it appears to have stopped, if it hasn't stopped within a 10 minute time frame proceed to the next step.

Plug the phone into a computer via a USB connection.

You will see the following options.

  • Mass storage
  • Webcam
  • COM port
  • PictBridge

Ignore all choices (!) and press on the RED (cancel call) phone key.

kb-article-odyssey-unlock-instructions-11-14-09-step8.jpg
The phone should power OFF at this point.

kb-article-odyssey-unlock-instructions-11-14-09-step9.jpg
Switch the phone back on and go into the settings menu

kb-article-odyssey-unlock-instructions-11-14-09-step10.jpg
Select network setup

kb-article-odyssey-unlock-instructions-11-14-09-step11.jpg
Select prefered mode, select GSM preferred and press OK
This step is crucial. If the change does go through you'll see mode switching to GSM, then to OK.

kb-article-odyssey-unlock-instructions-11-14-09-step13.jpg
If it goes through smoothly go to Settings again, and click on 'Restore Factory settings...
If it the phone doesn't accept the setting you'll see mode switching then it will display UNFINISHED.
If you see that message, please go back to the first step and do everything over again. The definition of madness is doing the same thing again and again and expecting different results. But it's worth a try.
You'll be asked for a password. The password is 1122. If that doesn't work try 1212, 0000, 8888, or 1234.

kb-article-odyssey-unlock-instructions-11-14-09-step12.jpg

A message will appear. Click Yes.
When the phone starts up again, you'll see a Chinese message. It's asking you to click on the screen for screen calibration. Click on the touchscreen.
Once that's done you'll be shown to the main menu.
Oh No! It's In Chinese!
Fear not...
To change the language back to English, just go to SETTINGS (the gears/cogs icon).
Then choose menu item 4, then 3 and you'll be able to choose English.
Still more steps...
Go back to SETTINGS, then NETWORK SETTINGS, then click on SIM1 network setup (or SIM2 network setup depending on which slot you previously put into WLAN Only).
There you'll be shown two choices: Network Selection and Preferred mode.
Make sure that Network Selection is set to AUTOMATIC and not MANUAL. If it says MANUAL, go in and change it to AUTOMATIC.
As for Preferred mode it should say GSM Preferred. If not please start the beginning again.

M001 Phone when trying to make a call it says : NOT ALLOWED DIAL"


This is for another similar clone marked with the "vaio" name but it might be useful to someone out there. I found that by following solution one above (thanks Mrfixit) to step 6 as below and then following the second part of what I found at http://chinamobiles.org/archive/index.php/t-16088.html worked for me.

BUT THEN

Connect your mobile via USB cable to a PC, DO NOT CONFIRM any connection mode at your mobile, just and ONLY connect the cable!!!

11. Press the Menu button (second from the left, the one with the seven small dots on it) until you are at the main menu with the 12 icons on the display.

12. Go to "Settings" --> "Network Setup" --> "SIM1 network setup"

13. Go to "Preferred mode" and choose "GSM preferred" or "GSM only"

14. The mobile will switch to your selection, but the message that it will stays on display. Do not press anything else, just wait for about 10 - 15 seconds.

15. Disconnect the USB cable from the phone, it will show you that it has switched to your selection.

"Not allowed to dial" new c5000 wi-fi phone


Guys I had the same problem with the k599 Sciphone and none of the solutions found on the internet helped me. New chinese models tend to restart after testing is over and this results in turning the wifi application on. So I spent many hours on thinking how to bypass this function and this morning I woke up with an idea that really worked!! The steps are quite similar with the ones followed to debug older models:

put 2 chips on cell
Disable WLAN.
1-enter in factory mode *#3646633#
2-go to RF Test Tool
3-choose GSM, confirm OK!
4-go to Power scan
5-Select Band DCS1800 click OK
6-the cell frozen
7-wait for 3 minutes testing
8-while testing connect to a pc using the USB cable (do NOT select ANY of the options appearing on the cell screen)
9-Click the CENTER button of the cell until you go back to principal menu
10-go to settings/network settings and choose GSM Preferred or any other option (except WLAN only!!)

In this way the cell does not reboot, and the wifi application stays off, so the option can now be changed...

Hope this helps!
