ZTE MF90 Bolt Unlock failed

[iAlphard]

Hi,

I just tried to unlock the MF90 bolt with the new DC software. I followed all the step in tutorial, it said succeeded but it still locked. My 7 credits also already taken. Anyone can help what should i do? Please check picture attachment. Ty.

This is the modem after unlock attempt.

[iAlphard]

So i tried to detect it with older DC unlocker and it is still locked. Help please.
The weird thing, when i detect it with the newest software, it doesn't say locked or unlocked below the NAND Flash information.

You must restart MF90 by removing it's battery for more than 5 seconds, then place it back and only then unlock process will be finished.

Also if possible please provide screenshot of Web UI of the device.

Old version of DC-Unlocker does not show correct lock status? Have you restarted device after unlock? What do you see in WEB UI of the device? Does it show there "Valid SIM card", but no signal or it says USIM or SIM is Invalid?

web gui

[Valdemaras]

Try to perform unlock for it again - detect and click Unlock button in Unlocking tab. Then restart device (Turn off device, remove battery for couple of seconds, then place it back, turn device on) and check web ui again, see if it's same. Unlocking same device won't require additional credits, just log into server with same account/dongle before unlock.

You must check it with one device only. So after you have attempted unlock it second time and restarted device like explained it said on web ui that it is still locked?

Please answer my question fully, it does not matter how many times you perform unlock it matters only if you do it all correctly - you must unplug device from usb , turn it off, remove battery, keep it that ways for 5 seconds or so, then place battery back, turn on the device and check again. If you fail to restart device correctly unlock procedure won't be finished.

i do exactly the method you told , but still can't have green light and still locked .

[iAlphard]

The method is definitely not working. I tried that couple times already. When i did it the first time, it was green for couple seconds but then turned back to red. What gives? And i have no more credits to try. Please help.
