How to unlock: Huawei E3531s-2 O2 Prepaid

[Drachenorden]

Hello,

I recently bought 7 credits to unlock my Huawei Mobile Boradband O2 Prepaid-Surfstick.

The following tutorail doesn't work for the Huawei E3531s-2 (HiLink) > modem not found?!

Any ideas?!

Thanks!

Maybe you use this modem for internet connection at detect time? Modem can not be used at detect time. Is web-ui closed at detect time?

The HiLink Web-Ui ist closd at detect time - doesn't worked with the tutorial: https://www.dc-unlocker.com/HiLink_m...nlock_tutorial

I solved the problem otherwise: only a simple Firmware-Flash with 22.318.05.00.00 Universal > ++++++++++++++++++++++++
22.x = HiLink; 21.x = non-HiLink

After that E3531s-2 already unlocked (!)

Therefore, could you refund the credits (7 €), please? PN sent.

Thanks.
