Hello, I've managed to flash the wrong bootloader (for et7000/et7500) and I don't find the one for my box... ET7100 V2
I found the name of the file, but that's it.. Xtrend-ET7x00-CFE-20170517.zip
Does anybody still have this saved ?!

I’ll do my best to find the bootloader for the et7x00 for you.
Please wait a moment. I’ll check.
Edit: I found one but this one is older. Don’t know whether it will work on the 7100.

Mijn schotel is een T90 met 10 LNB's. Daarnaast voor de fun nog een draaibaar systeem met een Triax TD 78.
Dreamboxen heb ik niet meer echt actief. Verder heb ik ook nog een een VU+ duo2 met 500Gb harddisk + een VU+ Uno, Zero, Solo 4K, Ultimo 4K, Zero 4K, Uno 4Kse. + ook nog een Xtrend ET7x00. Daarnaast heb ik ook nog diverse andere modellen w.o. een Formuler F4, ET8500, ET7500, Mut@nt 2400HD, Xsarius Fusion HD se en verder nog wel het e.e.a. waarmee op verzoek vanalles wordt getest. Iemand moet het tenslotte doen. 
Los van de eerder genoemde modellen heb ik nog wel een rits aan testsamples als Mut@nt 2400HD, HD60, GB UE4K, GB Trio4K, Maxitec Multibox combo en Twin, Octagon sf8008, sf8008 mini en last but nog least enkele modellen van het Grieks Duitse Edision.
Voor centrale opslag van media gebruik ik een Qnap 219P met tweemaal 2 Tb harddisks + een Synology DS414 met 12 Tb Totale opslag.

That is the false file I flashed... it's for 7000/7500

Thanks, but also not there...

Why did you flash the bootloader?
I don't think there was ever a bootloader update for et7100 v2 for it to be released.
When I get mine, I can try to read the bootloader if it's possible and post it here.

USB flash wasn't working, and also it didn't booted when a flash was inserted (even a empty one)...
I've tried the Serial debugging and always when a flash stick was inserted in one of the USB ports it will throw an exception and say "rebooting" but stuck there...
I thought reflashing the bootloader would solve that, didn't paid enough attention though... and it is bricked now, the bootloader doesn't seem to exist anywhere no more...

Same problem with the Qviart Dual 4K. Small USB devices work, but with larger ones, or a USB disk, it hangs in a boot loop.
I wouldn't be surprised of the ET7100v2 is from the same OEM manufacturer, given the fact Xtrend went bankrupt quite a long time ago.
Currently in use: VU+ Duo 4K (2xFBC S2), VU+ Solo 4K (1xFBC S2), uClan Usytm 4K Pro (S2+T2), Octagon SF8008 (S2+T2), Zgemma H9.2H (S2+T2)
Due to my bad health, I will not be very active at times and may be slow to respond. I will not read the forum or PM on a regular basis.

ET7100v2 should be the same as Octagon SF138.
Try this CFE.
If you run out of options use at your own risk.
Not tested this!

If your box is bricked and you find a nice time to invest in a new hobby.
You can try bringing it back to life again with Broadcom Broadband Studio.
And perhaps with onboard jtag serial connection if present.
Or else buy a new one.

I got the box. If somebody could guide me how to dump the bootloader, I will gladly post it here. The seller told me that the bootloader on the box is the latest one and that he doesn't have the latest bootloader.

But the question is, how to find that out?
I can log in with telnet and I see different mtd parts but I don't know which is for bootloader.

I was sent this version of the ET7100 v2 bootloader by a friendly guy from ellano.sk. Beware, I haven't tested it myself.

It looks ok to flash together with the OATV firmware files.
