Samsung Proshivka Nand

Since my board is bricked. I inspecting board more for revive it back. Board belongs to UA40D6000.

Powered by Samsung's V-NAND technology, the 850 EVO. Samsung 860 EVO 500GB mSATA Internal SSD (MZ-M6E500BW) by Samsung. $97.99 $ 97 99 $109.99 Prime. Samsung Shows Off A Z-SSD: With New Z-NAND by Ian Cutress on March 17. Samsung has snuck up behind everyone with their new Z-SSD product line. Z-NAND is ultimately still baked in as NAND.

So I identified 2 flash chip at D series HW. One of them is SDIN502-2G Flash which is used in Amazon Kindle. This chip used as main program storage, holds /dev/mmcblk0 device.

And other one is Samsungs Flash NAND chip, KFG1GN6W2D is used for /dev/stl0 device. This devices 12.th partition (/dev/stl/12) mounted as /mtd_rwarea. I needed to change this chip content. Probbly by (un)soldering.

Decode: It's Samsung OneNAND (KF), Single chip (G), 1Gbit (1G), Technology (N), x16 Organization (6),???Volt (W), 2KB Page architecture (2), Version d? (D) -HIB6 = Package format? (H), Industrial Temp (I), Include Bad Block product line (B), 66Mhz (6) Re-programing this chips will solve the my bricked TV problem. If you have any datasheet belong to those chips. I will be happy.

Then our only target is KFG1GN6W2D, since both start.sh and rc.local kept here. Anyone know how could we handle this chips via JTAG. Also heard that soldering BGA's is a problematic due old solders make noise. After removal chips balls became defected. They needed to be re-balled for re-install.

Re-Balling machines are too expensive. But I heard there is another cheap solution for that. And also since this PCB's are lead-free, unsoldering the chips require more heat. This heat also hazardous to chip. I think I let this soldering job to specialist Before I needed to inspect what I could make via JTAG ports. Nobody wrote: Maybe I'm wrong but I see 6 holes oooooo and next to them other 5 holes ooooo.

They look more like I2C EEPROM serial interfaces to me. Both of them. Probably no relation to JTAG and/or OneNAND flash whatsoever. Picture is a little blurry; can you post pin description in text form? I can't post better pictures, I made them in a hurry and I should open the tv to make new ones. They look like i2c bus to me, they have SDL SCL SDA lines labelled.

The jtag picture is also blurry but 'almost readable': Labels should be: PLD_GND PLD_TDO PLD_TCK PLD_TMS PLD_TDI unreadable.
