Everybody should stay away from Innosilicon, due to it's long bad reputation, and extremely POOR quality of the chips and miners.

Below is a proof of their earlier unfair & lier behaviour.  

Look at bitmine.ch stolen technology, insolvency of bitmine.ch years ago, due to scams from Innosilicon:

Innosilicon. The company that we engaged for the development of our A1 CoinCraft chip ended up in being BITMINE’s biggest failure. We engaged this company with a regular contract and entitled them to develop our 28nm ASIC based on our know-how and instructions, along with the full turnkey process of creating the mask, wafers and IC packaging. We had signed a contract that was expecting to guarantee us a one year exclusivity on the chip, however at a later stage we received proof that Innosilicon was plainly violating the contract from day zero and selling our own A1 chips to whoever inquired them directly. Once we pointed this out, they simply stopped answering our enquiries and disappeared, putting us in obvious panic because we had an extremely tight schedule and obligation to deliver the miners on time and they knew that perfectly. So, once they knew how attractive the market we were into was, they forced us into signing an amendment to the contract where we allowed them to sell the A1 chips to third parties. Additionally, they even forced us to write formal excuse letters for the “false” accusations under the threat that if we hadn’t signed them, they would just delay the supply of the A1 chips so long that they would be worthless.
Once the first production lot of chips, with a delay of nearly two months and a performance 50% worse than promised was delivered to us, the issue of “yield” popped up. Innosilicon repeatedly delivered us broken chips or “junk grade” ones as part of the purchased (and paid for) lots, forcing us to place ever bigger and bigger orders in order to fulfill our customers’ orders and eventually draining out most of the company’s money. Out of all the ordered chips, a huge part of them were simply not working and could only be thrown away in the garbage bin. Here you will see for yourself the pictures of the piles of tens of thousands of worthless junk grade chips still sealed in their original packages. When asked about clarifications, they claimed this was “normal production yield” but failed to provide any relevant document that could certify it. It is also worth mentioning that while we were struggling with thousands of junk chips, the A-grade ones could at all time be purchased in Hong Kong directly from their Chinese resellers, at some point even at lower prices than what we ourselves paid for.
At the end of this horrific experience, we had paid to Innosilicon in 2013 and 2014 a total of more than 8 million CHF but received only a small amount of usable A1 chips, causing us a huge financial loss. Therefore, we enquired two different lawyers in order to evaluate legal actions against them, but ended up with answers that more or less said that the chances of getting our rights respected from a Chinese court against a local Chinese company were close to zero. We only later found out this is a common practice from Chinese companies, regardless of the written agreements you make with them. (http://en.wikipedia.org/wiki/Intellectual_property_in_China)

I am afraid your hopes are worthless.   Innosilicon is EXTREMELY BAD COMPANY.  Their miners are catching FIRE all over the world, and they are reluctant to compensate the burnt miners.

My mistake, they issue so many updates that I can't seem to catch up!
I updated mine 3 days ago with the latest version released earlier this month.
Didn't realize it had an update already.

Update from 29.01.2018. Today 29.01.2018.

Are you shure, that your asic running for 3 days, sinse update?

I've installed the update. Can't see any noticeable difference when it comes to hash rate or temperature.
It's been running it for 3 days with no issues.

Anybody have install new update from 29.01.18?

How your asics feel himself after that?

So I managed to do the mandatory hardware update that Innosilicon released. I thought I would share my experience here.
First, I tried to remove the capacitor with a soldering iron. It didn't work out at all.
This time I tried with a unsoldering air heat gun and had somewhat better luck.

The capacitors on the first two has boards did not come off how I had imagined they would. They literally turned to dust after putting the hot air on it and trying to remove it with tweezers. I ended up scraping them off the board with a pin.

The capacitor on the last hash board actually came off in one piece, after a lot of heat and wiggling. Heating it to 380 from 1 cm away for 30 seconds is what the update documentation recommends, but in my experience it was not nearly enough to loosen the capacitor. It takes much more convincing unfortunately.

I think that unless you have VERY good eyes, a steady hand, and a good unsoldering air heat gun, I would not recommend trying this as a DIY type fix.
I consider myself quite lucky to have accomplished this without causing harm to any other components. The capacitor in the images is really really tiny, and is in a very awkward spot which makes it hard to get at. There is also a large heat sink in the way that makes it even more difficult.

Here are some images I managed to snap in the process.
The before and after photo is not the exact same hash board, but you get the idea.

I have heard some bad news when it come from Innosilicon, it seems that they are lacking heavily on the customer support side of things. I think that this company does have a shot at beating out Bitmain, which has been synonymous with the ASIC mining world. I just hope that they can get their customer support and pricing under better control, I have bought miners from Bitmain at or around the 1400-1800 mark but it seems Innosilicons are quite higher on average. I wish there was more open innovation when it comes to miner design, be it hardware, cases, thermal... or what have you. I know that there are some bright minded individuals that would hopefully love that concept. I have been thinking about starting an open consortium on this issue alone, whats everyone else s thoughts? 

Poor one out for the fallen A5's
They're bursting up in flames.

In classical Innosilicon fashion instead of addressing the issue head on, they decided that they were in no way responsible for what happened because they feel like they somehow address this issue by simply releasing their "mandatory hardware update" and expecting everybody to be able to fit it themselves.

An analogy would be:
"Hey we know we sold you a new car that is still under warranty, but instead of recalling it because it might catch on fire, how about you void your warranty, take it apart and fuck with very intricate/delicate components or pay somebody and hope they can fix it for you?"

I mean, how irresponsible or naive can they possibly be? The thing that gets me is that they don't see anything wrong with this! They did at least offer to help to address Giga Watt's issues.. by telling them to contact their support email. But as we all know, that's not saying much because of how unresponsive their support staff has been in the past.

Anyways, here are some images of some A5's looking extra crispy. Not for the faint of heart:

i bougth 8 miners  and i have some money leave but nobody anwer my emais about this money ,
Hello,

We are asking about the PSU because it's free PSU for you.
The price for 8 units of A5 is 79,992USD. Shipping fee for 8 untis without PSU is 428USD.  Shipping fee with PSU is 604USD.
You paid 83663.66USD.

Hello,

today i tried to connect my a5 dashmasters.

I plugged in miners,and im using mobile brodband 4g lte router.

All red lights are flashing right, miners seems to work nice,but it doens't start to mine ( hash ).I updated to last firmware ( 2018.01.05 )


I tried diff pools zpool,nicehash,miningpoolhub, but nothing works.

Also miner is plugged into power extender, can problem be there ?

If i run debug through telnet, I can't see chip temperature and in the end it writes something like voltage rumble/problem something like this...

Anyone can help?

Hi, I've a A5, can you upload the PDF! I don't recive that mail. Thanks

Innosilicon is really BAD BAD BAD. I hope that no one here will be their future victims.

It's tragic but hilarious. Can you imagine Samsung saying "yeah, that galaxy note thing can catch fire, here is how you repair it yourself"

For anybody curious about the newest mandatory hardware fix to avoid overheating the A5, I took it apart to see whether or not it would be something I would be able to do. Turns out it is not something I can do with standard soldering equipment. The capacitor is microscopic. I took some pictures that might help to scale what Innosilicon is actually recommending that everybody does to their A5. The fact that Innosilicon is not offering to cover this mandatory fix under warranty speaks volumes about what type of company they are.

These guys have been around for a while though. People have always been saying shit about them (and rightfully so). Yet there are still some who buy from them. I knew mining was a sellers market, but this is crazy.

Wow. There's got to be legal action that we could be taking when it comes to things like this. They can't just guarantee a warranty and back out when anybody goes needs it.

I've actually never tested my PSU that came with it because I already had a APW3++ on hand that I'm using for the A5.. I wonder if mine works!

Even the last update should be covered under warranty seeing as it's mandatory. I bet that now that we open up our miners (those of us that have sealed warranty stickers) to do the latest hardware update, then they are going to start saying that we voided our warranty because the seals are broken.

I've never heard of a company that blatantly treats their customers so badly. Maybe it's because they usually don't last long enough for word to get around...

For me, I've struggled to even receive compensation for a PSU that was dead on arrival in November 2017. Of course, I promptly bought a new one on Amazon to get the A5 operational for $190.

They only want to send me a coupon for $60 as they clearly do not stand behind any "warranty" that they list on their website. Considering how much money I've spent on the A5, the idea that they wouldn't offer full compensation for the whole PSU or a ship a new unit is beyond amazing. Add to that all of the issues with the actual miner, I hope no one else is foolish enough to send this company another penny. Bitmain 100% from here on out. They are not perfect, but they are MUCH better than Innosilicon.

I seriously lost it when I saw the email. I will never buy from them again.
