      also posts #46 saying the some mainboard RST pin 7 is empty solder pad then add 10 k resister there and my mainboard pin 7 is not connected to resister as well

      also can it be a issue of RT809H Drivers ?
      choose MEC1653#ISP from menu, duble click on it. Told you before, READ ALL posts from this topic, users are willing to share infos but you also have to work a little bit. Look at the pins of your picture, I marked them with what wires you have to connect. TMS to pin 1 of programmer, TDO to pin 2, GND to pin 4 TDI to pin 5 TCK to pin 6. If it doesn't work you have to add 10k pull up resistors between pins and 3.3V or you have a problem with motherboard, I see there is a problem around pin 6 where is 3.3V. Check if you have resistors R8257 to R8530.

        Thanks, I solved almost all errors, only 2202:Product Name is Invalid. I did look in all menus of LMU and still didn't figure out what to do. Please help!

              Re: mec 16xx dump with info block

              Hi People,
              I have an X13 YOGA Type 20SY.

              I read the Flash from the "MX25L25673GM2I-08G" IC, resulting in a 32MB big file. Unfortunately, the Lenovo Auto Patcher does not seem to work in my Case.

              So I wanted to ask if the Vertyanov Device is the way to go for me!

              Any help would be greatly appreciated.

              Regards

                Re: mec 16xx dump with info block

                Hello All,

                Iam trying to repair T460 NM-A581,probably,with bad EC FW.
                I bought/have a RT809H.

                1. How max. long can be debug cable(prog.device-MB)
                2. Maybe someone know where is JTAG_Enable resistor?
                Debug/JAG connector is J9(I hope),also there is some Test Points near CPU(TDO,TMS and so on)

                Thanks

                      No PULL-UP resistors to JTAG signals needed or 3.3v power suply as pin 6 has 3.3v only connect direct to svod3 all 6 jtag pins.
                      PULL-UP Resitor must move to PULL-DOWN like attached photo and put back after every step.
                      Thank you for all the information, it is GREAT!!! I am able to read MEC1663 & get the 256KB file which I attached. Kindly inform me now from where will I get an unlocked file (Without password as mine has a password), or someone can kindly auto patch this file for me, I would appreciate. Mine is a Lenovo Thinkpad T490 (Motherboard NM-B901 Rev:1.0). Thanks in advance.

                        If you were able to read MEC1633L chip, the next step is to ERASE it and then to PROGRAMM it with the file that you saved. The master password is not stored in this file that you saved, but in an EEPROM area on MEC chip as far as I know, so when you erase MEC chip the EEPROM contents get erased too! Then you will have to use Lenovo Maintenance Utility to type the missing information (model, serial number, etc.).

                        As far as I know some JTAG EC/KBC programmers can access the EEPROM directly and clean it removing the Supervisor Password, without having to save any file and later needing to use utility to type the laptop missing information.

                          Thanks so much "AAAC"., I will do what you informed me, I will use Lenovo Maintenance Utility instead. Just one more thing, have I got the correct size of the file??? 'cause I was reading the thread that the file can also be 290KB., Just wondering whether my file size 256K is the right one? I would appreciate if I can rectify this confusion. Thanks

                            Please ignore Post #252... I programmed the copied BIN files to the EEPRom & all is working fine without the PASSWORD. I can now edit the date & time. But no information about the Serial #, etc. To update this info I need Lenovo Maintenance Utility. Where about is this tools to put in all the data for Thinkpad T490?? If anyone can give me this info. Thanks

                              The missing information is printed on stickers fixed to the motherboard, make sure you have all the information so you do this procedure at once, instead of leaving empty fields and having to come back to complete them.

                                  Yes, there may be another sticker in the memory slots area too.

                                    Thanks for all the information "AAAC". Now all is set & no errors at all. Only in the BIOS I see "ASSET Tag Invalid". No errors though, but how will add the info of ASSET Tag?

                                      You may need to use another utility, as I don’t remember seeing that field while using the Lenovo Maintenance Utility.

                                        Yes I saw the "Write Asset Tag" in another Lenovo Maintenance Utility, I will make the changes booting from that software. Thanks for all the help.

                                          the solution presented in this topic only works for intel models, right?

                                            I need a BIOS dump for the Samsung S49CG934SU monitor
                                            by Habble7
                                            The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

                                            Suspected Cause:
                                            I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

                                            Troubleshooting Attempts:

                                            DUMP DVR HIKVISION DS-7208HGHI-K1 (80389 Rev 1.3 Firmware)
                                            by Mephysis
                                            Hello guys i really need help, i recently updated my DS-7208HGHI-K1 and it somehow got bricked, I've got it up and working now by flashing a new dump file i found but the serial number is really wrong and the uploader of the dump file probably intentionally did it.

                                            I still have the bricked dump file is it possible to transfer the serial number of the "bricked dump" to the "working dump"?

                                            Power supply Manson NTP-5561 (5661) LCD controller dead - PIC18F87K90 HEX dump required

                                            Hello!

                                            i got a damaged Manson NTP-5561 (60V, 1,6A DC output) and and the main issue is that the controler IC for the LCD display has a short. The controler IC PIC18F87K90 is mounted on the back of the back of the LCD. Vss-Vdd = 3 Ohm. The 5V and 3,3V power line was killed as well, but that is not a problem. A new LDO 3,3V and 5V 7805 is already ordered.
                                            Replacing the PIC18F87K90 is necessary but that makes no sense without having the HEX dump of the new controler.

                                            Does anybody have such a power supply and could do a HEX dump of the Flash and EEPROM memory?

                                            Hello all, as the title says, I'm very much in need of a valid firmware dump of a Anycubic Photon 5.5 3D resin printer. It's stored in a Winbond 25Q32, so it's 4Mbyte.

                                            Here's a little background for my request. A few weeks ago I bought this 3D printer from a guy who had moved on to a PLA printer. I got it at a vey reasonable price, as it was in a defective state. The seller told me that he had experienced a power failure during a firmware upgrade, after which the printer appeared to be dead. He thought the firmware was corrupted in such a way that the printer was now bricked. As he...

                                            Hi Everyone,

                                            I'm facing a problem with a locked bios with a password and i can't find how to remove it...

                                            The small computer is only booting on a M2 ssd Windows partition and i get a "signed partition error" if i try to boot on the same SSD with another Os (linux for example).

                                            the Computer is a Unowhy small pc

                                            After failling trying to boot on other "none Windows" partition, i wanted to try to remove the bios password.

                                            My first attempt was to get the bios dump from windows...
