My Pangolin Trouble is Halfway There but Still Stuck...

I'm seriously over Pangolin and Microbit... Total garbage with outrageous return fees and terrible customer service. My units arrived used, with leftover glue from old stickers and other clear signs of wear. My nightmare isn’t over, just throwing more cash down the drain for absolutely no BTC mining done. Oh, and getting tech support is a joke. You gotta go through Telegram and give them remote access to your computer via TEAMVIEW. Two HUGE security issues right there. Plus, you have to download and learn how to use both programs, and then try to sync up with someone across 12 time zones during THEIR hours. Even then, they just tell you what you already know... THE UNIT IS DEAD, and you have to send the whole thing back. The software/firmware is terrible. They claim there's a low power setting, and there’s an option in the software for it... BUT it’s NOT enabled or supported. Seriously, that was the ONLY reason I bought this junk, for the supposed efficiency. The units that actually work have no fan control, running at full blast all the time, regardless of chip temps. And they overheat quickly, plus they’re SUPER LOUD. They even arrived a week late. Any chance of making a profit is completely gone... I’ll never earn enough to cover the cost of the faulty unit I had to return. They're worse than Bitmain... UPDATE JAN 23rd So I got one unit back, and it’s working as expected. They even covered the shipping cost for the return (actually reimbursed me). But the second unit was found to have a connector board issue. They didn’t offer to send a replacement right away... In fact, they want...

They were removing stickers and leaving glue like that since M3 models. Some people thought it was because they were originally branded as the scam Kodak KashMiner. The real issue may have been from pending litigation with Bitmain over their PSU patent and claims their former engineer, who founded MicroBT, stole designs. That patent was supposedly revoked during litigation, but there was recent news that he was being held by police for new intellectual property infringement claims made by Bitmain involving tens of millions of yuan. They are probably removing the stickers again to avoid units being seized.

I mean if they recycled chassis that's awesome. It's a metal tube might as well recycle it no?

Shitty, sorry to hear about that. I've dodged dead units so far. I had a limpy t9+ so it was an easy decision to not send back the entire machine for a simple repair and hope it came back working. That's always been the biggest BS policy around that you pay the return shipping for this gear when it arrives dead. I got lucky with Pangolin. They tried, but I hated having to be on TG and using Teamviewer to essentially watch them load a couple firmware versions hoping to fix my issue. In the end I was still left with an erratic unit that couldn't handle LP mode very well. So a small loss when compared with shipping costs. My problem was a little different as the unit would run just not as well as it should have, so I made a case for at home repair to try and swap out possible issues like a PSU or a bridge.   Personally I would try and get them to cover half of the return shipping costs or something. Play the you were late card, and the fact that you purchased other units from them. It never hurts to ask in these situations. The glue/sticker issue they have said on telegram was to facilitate smooth shipping and export/import. I guess that's a reason.

I got 1 m3 8 m10 1 m21s 1 m20 1 m10 was a piece of garbage basically an 800 dollar loss. all other gear was okay. although right now 1 m20s is down and i dont know why. i will look at it on friday the 20th what really hurt whatsminer was the really slow shipping for the august purchases.

And now my second M20 died after less than 5 hours. Glad I did not sent it off to host before testing. So almost 5 months since paid for in full..... and I have two useless miners. The first unit (Returned) arrived in Shenzhen 2 days ago but has not been picked-up yet.

to up date my dead pangolin m20s. it fried the psu. not surprised as they really pushed the shit out of it. it drew 3400 watts 24/7/365 out of a rated 3500. it did run from may to dec. it was a beta model. i found a company in north carolina hmtech they sold me a new psu for 275 shipped in two days. the psu frompangolin would have been 150 + 58 = 208 plus some tax maybe 225. so,it did cost more but i got it four or five days faster then pangolin so it earns 40-50 bucks in that time it is breakeven. since my gear was out of warranty and beta.  i had a p20 psu not a p21 i had may firmware for a h6 controller not a h3. so i flashed with pangolin liinked firmware. it did not work spent time on microbt website found h3  and h6 firmware. flashed with h6it took and my m20s is running. lost 17 days of mining and paid 275 for psu. could be worse. i could have your issues which would be more costly.

Over 6 months now and I still have one dead M-20 unit....they have not replied to emails for over 1 month. while on telegram no reply since I notified them the diagnosis and instructed repairs of board replacement did not solve the problem the unit is still defective. 2k U.S. rip off for ZERO return.

That sucks. Bitmain is just as bad for warranty IMO although I've never dealt with them for DOA. My Z11 had the middle hash board fry in less than two weeks. I couldn't even pay them for a replacement board and have been running it with two boards since. The only company I've ever had good luck with sending me replacement parts for free under warranty was Canaan.
