Hi and greetings all my first post

I recently reinstalled windows, went fine. Then downloaded a bunch of drivers from the support.dell.com site for my alienware.

One of them flashed the firware for my bd rom and now it reads as a CD rom in windows explorer.

Running the bd firmware, it just says it keeps updating but never does.

How can I restore it to a BD drive?

In explorer it says CD drive it is actually a BD drive, pushing eject does nothing, if I hit eject via right click in windows explorer it says device not ready.

My Computer is an Alienware Area-51 ALX

Processor: I7-975

Ram: 12 gb

Video: dual amd 4gb sapphire 6990 (total of four gpus)

When updating it says the drive is a SATA PLDS DVDRWBD 0d111 (this is wrong)

The drive should be a HLDS BH20N SATA HH 6x BD-RE which I read is really a LG BH08NS20 clone

any help is appreciated.

I have the correct firmware but it does not flash it just updates forever instead of actually flashing.

It does not read any discs and hitting eject does nothing, I need it to be able to do startup repair with the disc but I cant get it to read the disc.

Uh oh - You might need an external BD drive as this one might be toast.

If there is no jumper on the device to reset it back to factory, (probably not) - you are screwed.

There are 3 sets of 2 pin holes but no pin thing can I bridge them to restore the default?

these holes are located to the left of where something is plugged in maybe the power or data I do not know which.

I dont know about the jumper - find out who actually made the drive & see if you can find some tech papers on it.

Why dont you want a system change ? You get a brand new computer replacement for free!

If its because you dont want to start over -then clone your HDD, give them the PC, and when you get the replacement - upload your backed up image and you're ready to go.

my bd drive is a LG BH08NS20 clone trying to do some reasearch

I dont want a system exchange because they dont ahve this chassis available anymore and the aurora can not run these powerful cards.

If that's a hang-up for you, can you ask Dell to keep the chassis you have now and just put the replacement parts in there?

EDIT: Have you tried anything on this page? If not, I don't think it would hurt.

The holes are typically for the emergency eject mechanisms - nothing to do with firmware.

Best bet be to find a command line flashing tool for the drive (the LG version would probably be best) and hope it has a "force" option, in that it will attempt to flash the drive and disregard any errors.

You can't reset firmware chips, much like if you flash the wrong BIOS on a motherboard or graphics card they stop functioning. Its not like BIOS settings where its stored on volatile memory that has to be powered to store the settings.

Firmware sits between the software and the hardware telling the device what to do, if you have flashed it with a different model then the firmware is telling the drive to do something it can't do due to missing or different hardware in the device.

Once you have flashed it, that's it, it's done usually rendering the device inoperable, if its not detected by windows and its not ejecting it means the drive is dead, you can't bring it back to life without either replacing the firmware chip or replacing the full PCB with an exactly the same make and model PCB.

      "it opens up new doors for people who prefer using Edge, but cannot be bothered to configure a Microsoft account" You already have a Microsoft account if you are using Windows 11, because you can't set it up without one.
    • This is how much iPhone 18 Pro could cost after Apple's price hike confirmed

      By Hamid Ganji · Posted

      This is how much iPhone 18 Pro could cost after Apple's price hike confirmed by Hamid Ganji Image via Apple Apple CEO Tim Cook confirmed in a recent interview that the company may have to raise prices on some of its products due to the ongoing memory shortage. While he did not elaborate on the scale of the price hikes, new estimates suggest that Pro iPhone models could become significantly more expensive this fall. The Wall Street Journal and research firm TechInsights have come up with an educated estimate of how much the upcoming iPhone 18 Pro could cost after its launch in September. The estimate is based on current increases in memory and storage chip prices. For starters, the iPhone 18 Pro base model is expected to feature 12GB of RAM and 256GB of internal storage. According to TechInsights estimates, 12GB of DRAM for the iPhone 17 Pro cost Apple $39 last year. However, for the iPhone 18 Pro, the cost of the same amount of DRAM could soar to $145. Likewise, 256GB of flash storage that previously cost $13 could now cost around $51. Producing a base iPhone 17 Pro reportedly cost Apple around $582, but TechInsights estimates that the production cost of the iPhone 18 Pro could rise to $726. If Apple wants to maintain the roughly 47% profit margin it enjoys on the iPhone 17 Pro, the base price of the iPhone 18 Pro would need to reach $1,371. After standard pricing adjustments, customers could end up paying around $1,299 for the base model. However, that may not be the end of the story. As we previously reported, the iPhone 18 Pro is said to feature a variable-aperture lens, which could cost Apple at least 50% more than the current camera system. The estimated $1,299 price tag does not include the additional cost of this upgraded camera hardware. Once that expense is factored in, the base model could cost at least $1,399. A $1,399 price tag for the base iPhone 18 Pro would represent a significant increase over the current $1,099 starting price of the iPhone 17 Pro. If Apple wants to keep its upcoming iPhones competitive, it may need to accept lower profit margins.

    • Google Gemini co-lead Noam Shazeer is leaving for OpenAI

      By pradeepviswav · Posted

      Google Gemini co-lead Noam Shazeer is leaving for OpenAI by Pradeep Viswanathan Noam Shazeer is best known as one of the co-authors of the 2017 “Attention Is All You Need” paper, which introduced the Transformer architecture that now powers most large language models. He also worked on several major Google AI projects, including LaMDA, before leaving the company in 2021 to co-found Character.AI. He also authored the Sparsely-gated Mixture of Experts (2016) paper, which is popular among the AI community. After falling behind OpenAI and Anthropic a couple of years ago, Google brought Shazeer back in 2024 as part of a major deal with Character.AI. Through this deal, along with Noam, several other researchers returned to Google DeepMind. More recently, he was a vice president of engineering at Google and a technical co-lead for Gemini. Today, Noam Shazeer announced on X that he is leaving Google and joining OpenAI. In his post, Shazeer said it was a difficult decision to move on, adding that he was proud of the Google team and what it had built together. OpenAI CEO Sam Altman welcomed the move with a post of his own, saying Shazeer was one of the people he had most wanted to work with since OpenAI’s early days. Google has made strong progress with Gemini over the past year, closing the gap with OpenAI in several areas. But losing Noam Shazeer is a major talent setback for them, especially after bringing him back less than two years ago by spending a fortune. For OpenAI, the hire adds one of the industry’s most experienced language model researchers to a team that is already pushing ahead with ChatGPT, Codex, and its next generation of frontier models.
