Some E3's can be difficult to flash, use a 2gb micro sd card formatted to FAT32 and extract the firmware onto the root of the micro sd card, move jumper over as-per bitmain instructions.

Honestly?

there is a file located located in root called "core" which I am told is just a core dump file and taking up a ton of space which is preventing the firmware update from installing, I just ssh to the miner, locate the file in "/" and remove it with "rm core" then exit and run the firmware upgrade from the web gui without issue, it was really easy.

But to be honest, its not really worth your time, the e3's no longer mine ETC and ETH days are numbers, any other mine able coin has no profit unless you have free power

3 chains gone here as well.

Followed all instructions provided by the Bitmain Support page to upgrade to latest firmware with SD flashing, but i wasn't able to flash the E3 somehow even i made it step by step as suggested.

Can someone that managed the flashing through SD card make a guide/tutorial step by step? Pretty sure the Bitmain guide misses something or it would have worked out, not?

Thx in advance.

It just does not work. Even Bitmain said, it does not work. The E3 was the worst miner so far.

So nobody managed to flash the SD card so far? Seriously?

I have flashed from SD yesterday.
1.Unzip and copy T9+ firmware fails to SD. https://file11.bitmain.com/shop-product/firmware/t9%2B%20-SD%20Tools.zip
2. Insert SD and move jumper.
3. Switch miner on and wait 30 sec till blinking of both status lights simultaneously.
4. Power miner off, remove SD and move jumper to its original location.
Now you have fully functional T9+ control board which can be flashed by the E3 firmware.
5. Download E3 Firmware : https://file11.bitmain.com/shop-product/firmware/Antminer%20E3/Firmware/0072018071812344880187tM1RPd0668/Antminer-E3-20180806.tar.gz
6. Power miner up.
7. In Upgrade page select downloaded E3 firmware for flashing, uncheck "Keep settings" checkbox and flash firmware.

I’ve recently had the dreaded “socket error: connection refused” error. I’ve tried everything, finally got a board from eBay that already has the T9+ firmware on it. I can’t get it to flash to the E3’s. I’ve tried this and the new version, but I keep getting an error saying “cannot find signature”. Any help would be greatly appreciated!!

There seems to be a new firmware file. Did anyone try it? Or is it the same old one but renamed and without comments on the Bitmain page?

I have an E3 on nanopool, its mining fine (showing right calculated hash rate) but the reported hash rate is zero, does anyone know why this is?

Thanks

Has anyone found a solution to Request Entity Too Large problem or BB and CC ASIC status?

Hello,

I tried to update the firmware to fix the "BB' problem on chain#13 (like suggested by bitmain support), result: it change nothing, I still have the "BB" status.

To fix the "Request Entity Too Large problem" problem when upload firmware on web insterface:

Connect in SSH to miner, and add on /etc/lighttpd.conf:

Quote

server.max-request-size = 1000000
server.network-backend = "writev"
server.upload-dirs=("/mnt/tmp")

Commands:

Code:

$ ssh [email protected]
$ echo 'server.max-request-size = 1000000' >> /etc/lighttpd.conf
$ echo 'server.network-backend = "writev"' >> /etc/lighttpd.conf
$ echo 'server.upload-dirs=("/mnt/tmp")' >> /etc/lighttpd.conf

So are they worth buying? It seems like the cheapest way to add 180-190 Mhashes to my setup.

Guys, now these are available relatively cheaply, would you buy one or two over a gpu rig? How long is it until the DAG is too big for E3 to mine ETH? There will be other options then anyway right?

Cheers

The E3 will last until the DAG exceeds 4GB

My 2 miners missing 1 chain. I try to upgrade firmware with SD card but it didn't work.
The red and green light didn't blink. Have anyone help everybody with youtube step by step.
It's very helpful for friends. Bitmain said not clear about power on control board , plug or unplug
cable with hashboard, offline or online with Lan.

send back to them the hashboard for repair.

How to run this miner with only 2 hashboards? since one was sent for repair. It keep looping "error" msg on mining status and wont hashing only using 2 hashboards. I cant update the firmware too (via WEB and SD card).

Hey guys, thought I’d give my thoughts.
Ever since updating to Geth 1.18.14/15 on all of my nodes, the E3 miners on my pool dropped as much as 15% in hashrate. This seems to be associated with the miner update interval, which is now set at 3s by default, and does not respond well to update interval variables above 10s.

This means block templates are sent to the miner at an alarmingly fast rate.
Symptoms include high load averages (2+), and hashrate variation between 18-22MH.
More than a few miners have lost chains.
Pretty shitty.

6. Power miner up.
7. In Upgrade page select downloaded E3 firmware for flashing, uncheck "Keep settings" checkbox and flash firmware.

So we need to use T9+ firmware first via SD card (flashed), then use E3 firmware on web?

Anyone has experience by updating the E3 firmware, it can fix the missing chain? i just dont get it. I think the hashboard has the problem (same as D3, missing chain cannot be fixed with updating the firmware).

I tried it, didn't work for me. Even the T9+ SD didn't work as the status lights just don't blink. Somethning just isn't working as it should. I have flashed a lot of Baikals so far, so flashing isn't something new to me, but with that E3 i just don't manage to flash the control panel successfullly....

how you sent the board for repair? 1 hashboard has 6 asics boards on it (3 chains number ie 1,2,3 or 8,9,10 or 11,12,13). Mine is chain 11 is missing. One chain has 2 asics boards, so did you send whole 1 hashboard (6 asic boards)?

Yes, I sent the whole hashboard, you can know which chain in which hashboard by following their guide.
