Boulder police, along with district attorney investigators and members of the Colorado Bureau of Investigation, have been scruntinizing the home since Monday and may be in the home for up to a week. Chertezhi modelej tanov iz dereva. (AP Photo/David Zalubowski) 2016-06-05 06:39:36.

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

• • • Flash memory is an () medium that can be electrically erased and reprogrammed. Developed flash memory from (electrically erasable programmable read-only memory) in the early 1980s and introduced it to the market in 1984.

[ ] The two main types of flash memory are named after the. The individual flash memory cells exhibit internal characteristics similar to those of the corresponding gates. While had to be completely erased before being rewritten, NAND-type flash memory may be written and read in blocks (or pages) which are generally much smaller than the entire device. NOR-type flash allows a single (byte) to be written – to an erased location – or read independently. The NAND type is found primarily in,, (those produced in 2009 or later), and similar products, for general storage and transfer of data. NAND or NOR flash memory is also often used to store configuration data in numerous digital products, a task previously made possible by EEPROM or battery-powered.

One key disadvantage of flash memory is that it can only endure a relatively small number of write cycles in a specific block. Example applications of both types of flash memory include personal computers,, digital audio players,, mobile phones, synthesizers, video games,,,. In addition to being non-volatile, flash memory offers fast read, although not as fast as static RAM or ROM. Its mechanical shock resistance helps explain its popularity over in portable devices, as does its high durability, ability to withstand high pressure, temperature and immersion in water, etc. [ ] Although flash memory is technically a type of EEPROM, the term 'EEPROM' is generally used to refer specifically to non-flash EEPROM which is erasable in small blocks, typically bytes. [ ] Because erase cycles are slow, the large block sizes used in flash memory erasing give it a significant speed advantage over non-flash EEPROM when writing large amounts of data. As of 2013, flash memory costs much less than byte-programmable EEPROM and had become the dominant memory type wherever a system required a significant amount of non-volatile.
