entt2 - Easy Nand Tiny Tools

[u666sa]

I am creating this topic because @radeko asked me, what is entt2?

Easy
Nand
Tiny
Tools

There is version 3 out by the way, so entt3, lul

If we draw hierarchy of nand and emmc programmers known to men at the very top is UFPI with black licensing, right underneath it is entt2 or (entt3 now), and then we have T56. Now, T56 is no bueno when it comes to doing TV work, because you'd have your chip support, and the chip will be listed as supported, but it does not know how to work with keys, so its work is hit and miss. Both ennt2 and ufpi know how to work with keys so they are super popular in the tv and car ECU repair community.

Another thing is support, TL, T48, T56 have chinese forums, you post there and good luck. Your interaction ends with you posting a question and nobody answering. Your job and your customer at that point are walking out on you, going to your competition and pointing fingers at you.
Both ufpi and ennt2 have normal support forums which are pretty popular, an actual human being answers your noob questions in a timely fashion.

Now it's one of those unobnanium tools because of sanctions. But only if you don't know what you doing. You have to realize that you can't pay for them using swift systems, only mir, which you don't have in the west, unless you are able to open bank account in countries like Kazakstan or Armenia. The other option is to use bitcoin. As far as shipping, I do believe it goes just fine with the snail mail, at least I did send packages to the USA via the snail mail, 3 weeks.

Website is forums, it is here - https://www-ejtag-ru.translate.goog/viewtopic.php?f=8&t=343&_x_tr_sl=ru&_x_tr_tl=en&_x_tr_hl=ru&_x_tr_pto=wapp

Now, another good one, and this one is available for everybody, Z3x Easy jtag, it's pretty much excellent for EMMC. If we compare Z3x to UFPI here is a good quote of user that has them both -- UFPI with both nand and emmc, often reads crap, but at that it sometimes reads, when Z3x does not read. However ,, when Z3x does not read the contents are often crap to begin with."

So to summarize, TL, T48, T56 are excellent relatively inexpensive programmers with which you will have some problmes with certain nand and emmc chips.
UFPI is great and will read it all.
ennt2 is cheaper than ufpi, but is just as good.
Z3x is an excellent choice for emmc.

I am new to tv repair. And i want to know how to move keys from one tv mmc to new one  to make netflix to work without problems.
DRM Keys are in RPMB partition? And i need to clone RPMB partition? Probably is it possible to read RPMB without RPMB Key.
To write to RPMB partition KEY is needed. But this key is somewhere on USER partition and is unable to find it easy.
Solution is to generate new key on new emmc chip with 0 RPMB counter. or to write new firmware to old EMMC chip. Writing new FW erases RMPB write counter to 0.
Easy JTAG programmer is capable to dump and write FW to EMMC
UFPI is capable to write FW only to samsung EMMC chips. I find it in manual.
