Hello everyone,
So recently, I had my laptop's motherboard repaired. The problem was that there was no display on the screen, even though the laptop's blue light was on. My laptop was out of warranty so I went to acer support store and they said that they cannot repair but only replace the whole motherboard with a new one and that was gonna be costly.. since the processor and everything comes inbuilt so it would cost very much. But they advised if I could get the motherboard repaired from somewhere else, like some friend. So, my uncle had this friend and he fixed the problem. He said that he put a new IC in the motherboard and that costed 1/4 th of what it would have cost total if I would have had to purchase a new motherboard.
So everything was fine, but then after the laptop was delivered by my uncle, we tried to boot the already installed OS i.e Windows 10 pro x64, but it showed some error so we formatted the partitions and everything and then created the partitions again and then installed windows 8.1 on c drive. We installed windows 8.1 because it's what we had at that moment. All other OSes iso files were in my pc which was also to be repaired (same IC problem).
Now, the os installed successfully, all drivers were getting installed (used ethernet cable to download drivers), but my wifi driver first had this yellow exclamation mark in device manager (Network Controller was the name with yellow exclamation mark). I have tried all the tricks, all the known and discoverable things or left no stone unturned to solve this problem but damn, everytime the BSOD flashes up when I try to install the wifi driver.
So, my wifi driver details are: - QCNFA435 (the sticker underneath laptop had this name i.e "this laptop has come with bluetooth and wifi....." message)
QCNFA435 i.e Qualcomm Atheros QCA9377 Wireless Network Adapter
I've tried to disable to wifi driver and install driver successfully in safe mode, but when I enable the driver, the BSOD reminds me that my life is still a disappointment, I've tried the killer gaming driver, drivers from acer's site, used many softwares, even purchased a external wifi usb and that gives a BSOD, too.
Also, I cannot install any of the Linux distro I've tried till now i.e Linux Mint, + I cannot install Windows 10 (it gets stuck at devices getting ready 12%), I did leave the laptop for 6 to 7 hours but nothing happened, I tried installing windows 10 and when it gets stuck at 12% devices getting ready, I rebooted the setup to repair computer --> Advanced options --> command prompt and then c: -- cd windows/system32/drivers and then del QCAmain10x64.sys.. but after reboot the setup shows files missing/ damaged and tells to reinstall windows 10. So yea, this method, too. I even tried Britec's method of slipstreaming drivers, but it cannot delete the default network driver in DISM GUI. It is locked.
So yes, believe me when I tell you, I've tried it all and now only thing that can help me is the original wifi driver that my laptop came with pre-installed. I googled and many people say that the default driver version was 4.0.1.137... that's when everything was working fine.
So I google this driver's name with QCA9377 name but there is no way available to download this driver.
So my request to you, if anyone (or your friend) has the same laptop or network card/ wifi adapter, please let me know. Please help me get the default OEM driver for this QCA9377/ QCNFA435 wifi adapter.
