Hello everyone, I hope you can help me I have this SSD drive, however, when we short the SSD it cannot access Safemode, perhaps we are getting confused about short points, any clue will be of great help. Kind Regards

Did you do any basic testing (PMIC, polyfuse) before you started looking for safe mode test points?

Also check the input and output voltages at the load switch (?).

Hello fzabkar, thanks for responding. I attach the images with the voltages, also indicating that none of the inductors have continuity to ground in case it is of any use. In addition to this, could you tell me how to measure the PMIC? Kind regards Fernando

Those voltages seem OK to me. The PS6103-29 PMIC has 2 x bucks and 1 x LDO regulator. Therefore, in addition to 0.94V and 1.2V, there should be a third voltage near the IC. If you test the other capacitors, you should find this voltage.

Thanks for the guidance, and is there any clue for the cut lines to enter safemode? |

Maybe you could locate the Ready/Busy* pin within the unpopulated NANDs and short this pin to ground during power on? |

| Post subject: | Re: TEAMGROUP MODEL TM8FPD512G0C101 |
I'm going to try it, although I see it as complicated as it is not pins but pads, but I am going to look for documentation on the NAND chips to see if it is possible and I will indicate if I achieved something to help everyone. I appreciate your time, if you have PATREON leave it, this is the third time you have responded to me and your guidance is very useful, I would be happy to be your subscriber. Kind regards Fernando |

Looks like BGA 152 https://media-www.micron.com/-/media/cl ... 2-gold.pdf http://www.flash-extractor.com/manual/adapter_bga_152/ https://support.rusolut.com/portal/en/k ... bga132-152 |

Some SanDisk SSDs use the R/B* pin of the NAND as a Safe Mode jumper. It is electrically safe to short this pin to ground as it is open drain. https://www.hddoracle.com/viewtopic.php?p=22764#p22764 https://media-www.micron.com/-/media/client/onfi/specs/onfi_5_0_gold.pdf (page 28) Edit: I see @Lardman beat me to it.

Wow, thanks fzabkar and Lardman, so I guess I should extract the chips, locate the line of these pads, make the short and solder it again? |

| Author: | fzabkar [ February 16th, 2024, 13:08 ] |
| Post subject: | Re: TEAMGROUP MODEL TM8FPD512G0C101 |
Just use the unpopulated pads. No need to remove any chips. |

Hello, I am writing to update the result, unfortunately the SSD does not enter safe mode so I assume that the problem could be the controller chip since I cannot find any short circuit or components in poor condition in the electronics and I am already out of ideas, If anyone has one, I'd be happy to try it and provide the results. Kind regards Fernando

02/20/2024 PC-3000 core - Fixed a bug that resulted in drives on the PS5013 controller not being ready in safe mode. update the version and check |

Hello, thanks for the idea, I just updated it and the problem persists. |

Try connecting the drive via an PC-3000 Portable Adapter SSD PCIe x16. |

I don't understand, the unit is an M.2, what does it tell me is to use an M.2 to X16 adapter and connect the adapter to the X 16 adapter of the PC3000 portable? |

Do it this way.

Hello Agrail. Unfortunately it didn't work, but thanks for trying to help me. |
