Lexar SD 256gb Not initialized give cmd8 no answer in sd card adapter

Hello. It must be SM2704-based SD card with BGA-132/BGA-152 inside. We recommend you to do a chip off. For such cards we even have a good translator which will allow us to build a good image with File Structure.

can you guide me what to select from these as it is give me error i make chip off and inserted in adapter 152

[d_d_recovery]

Could be the wrong adapter, a bad chip, or its not been cleaned enough.
We need a lot more information to be able to help you.

[deyaa2012]

these adapter i used and shape of chip after desoldering and cleaning kindly have alook and advise

[d_d_recovery]

You might want to smooth those pads a little more.
And move the chip in the reader slightly each time you try to read it as these are not automatically centered.

This NAND is BGA-132, which is thinner than BGA-152, so you should place it directly in the middle of the adapter, it's important for a good contacts. In case of any troubles - please contact ACE Lab TS dpt. We will guide you with recovery steps: ts.acelab.eu.com

It's reading now. New generation of Micron NAND with 2.45V VCC and 1.8V VCCq

Controller is SM2704

Case was solved in PC-3000 Flash 9.0.21

i have same problem with
Pen drive Philips 128gb
Controller IS918
Chip: PF667-25AR
cleaned perfectly, I insert it into the BGA-152 reader, but it only gives me the incorrect ID 0x0000, is the chip burned or do I have to set the power?

[Roman_TS]

Hello. You should try to set 2.45V during the ID reading and check. After that, most likely you will need to adopt chip ID parameters for this NAND and set 2.45V inside.

Anyway, better to ask such questions in ACELab TS

Thanks Roman, i have update for u, nand read 2.000 V and CQ 1.800 id 2C2CD31C 32C60000

[Roman_TS]

Yeah, it's the new Intel/Micron low voltage chips. With a very bad quality...
