[compu829]

Fresh from the Windows Central forums, I present you the Lumia 820 Engineering ROM! http://forums.windowscentral.com/nokia-lumia-820/350899-[825]-engineering-recovery-ffu.html

Direct download is at: Http://mega.nz/#!k5xShaDK!YHr1p6a3yeH53jt3-58lbuCE4QiSH_rz9qfGeQK3HBg

Have fun!

*edit*

After finally digging into the FFU and checking things, this really IS a true engineering ROM and NOT a developer ROM.

This is Lumia 820's FFU not Lumia 825 which is even not existing.

Also in text he said Engineering Rom and in Tittle he said Developer !
as I remember Engineering Roms are much different as developer one

@ngame @djtonka sorry for all the confusion! you guys are correct. This is for RM-825 devices, which is a specific variant of the Lumia 820. I was on mobile yesterday when I saw it, and wanted to post if quickly in case it magically disappeared. I think you are also correct in saying that it is a "Developer" rom and not an "Engineering" ROM based on the name of the tar.gz file. I will analyze it today or tomorrow and post back.

Yes, It is a Developer ROM. (WP 8.0 GDR 1)
But not useful until it's "OEM DEVELOPER UNLOCK".
No MS Apps nor developer app's like diagnostic tools.
No special drivers/services. Very simple ROM

@djamol @ngame @djtonka

After digging into it some more, I can confirm this is a REAL Engineering ROM and not a Developer ROM like I thought earlier. Sorry for all the confusion!

@compu829 Don't mind, if I'm wrong. It's pure dev rom. There is also mentioned that version "Developer5". And so why it is signed ffu. ? Engg. Roms are like a more custom ROM'S.
@ngame you will find out more info in "OEM Device Platform Info" package's.
I've one question, what is a use of this ROM if we don't have an OEM unlock or Interop Unlocked.?
How we can use this as a REAL DEV ROM ?

Edit: At least can enable Mass Storage Mode ?

I want to see differences between these roms .
specially registry differences .
Developer signed Roms are flashable .
maybe I have to flash my phone from w10 back to 8.1 in these days and surely I will first try a dev rom to see if anything more presents or not
If we can enable mass storage mode all the things will solved as I know
because system files are not running so technically replacement of all files are allowed . (but where there's no sign check)

Even though it says "Developer5" it is really an engineering ROM. That threw me off, too. When I started looking at the "Platform ID", I discovered that it is for an engineering-only device.

I've tried flashing engineering rom on my Lumia 820 using windows phone image designer. It failed to install because of some security errors. So, I used thor2, disabled security check and was successful in flashing the rom. After flashing the phone is not booting anymore. It just vibrates and that's it. Not even Nokia logo is shown. I tried connecting phone to PC. But my PC is not even detecting the phone (in any mode, like QHSUSB_DLOAD). So, it is dead. Is there any way to recover the phone?
