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 220.127.116.11.00. After changing the SIM card, the Airtel E173Bu-1 modem was not asking for an unlock code.
Then I tried to write the unlock code using “Huawei Modem Code Writer V1.0b by Segmaster,” and I have got a failed error.
Before this, I had got success in other modems, so I have tried to write the unlock code in the Airtel Huawei E173BU-1 dongle many times, but the result was the same, fail.

After the various failed to unlock attempts, I decided to try the “CardLock Unlock Tool” to write the unlock code in my Airtel-branded modem. I was shocked as in the only first attempt, and I had the success to write the unlock code.
