ZTE MF90 BOLT INDONESIA Bricked after software failure

[lexons]

Hi,

I followed this link (https://www.dc-unlocker.com/zte-mf90...d-unlock-guide) carefully, all drivers downloaded and installed perfectly and then the software crashed. I restart it and the modem bricked. Only battery led is on, others are off.

then I followed the step to repair

at first attempt the step 1 works perfectly
then I followed the step 2, after few progress it finised with error

then I tried to repair it one more time by restarting the windows, restarting the ZTEQMF90BoltWriter_V8, unplug and turn on mf90

this is the main tab result

Let us know what you get now when you press Unlock button in Unlock tab now while only diagnostics port visible of your device, monitor device manager during this, if any changes make screenshot and attach it to your post.

Seems then problem is that your modem is stuck in download mode, even though it shows diagnostics port. Maybe you have original MF90 bolt firmware updater and could launch it to see if device will be brough back to normal mode? If you do not have updater try to download one from their website here http://www.boltsuper4g.com/ayo-updat...e-wifi-mu.html
