Today, I will talk about two Huawei modem code writer software which I have already introduced in the previous posts. Both, “Huawei Modem Code Writer Tool” and “CardLock Unlock Tool” are  great but I want to highlight something with you. Yesterday, I was unlocking one stubborn Huawei E173bu-1 modem. I flashed it properly and there was no error. After flashing the Huawei Airtel, my modem firmware was 11.126.15.0.00. After changing the SIM card, Airtel E173Bu-1 modem was not asking for any unlock code.

Then I tried to write the unlock code using “Huawei Modem Code Writer V1.0b by Segmaster” and I have got failed error.

Before this, I had got success in other modems, so I have tried to write the unlock code in Airtel Huawei E173BU-1 dongle many times, but the result was same, fail.

After the various failure unlocking attempts, I decided to try “CardLock Unlock Tool” to write the unlock code in my Airtel-branded modem. I was totally surprised as in only first attempt I had got the success in writing the unlock code.
