Re: LENOVO L14S G2 Where is point to connect?
There is no programmer that supports this chip yet,as you`ve already been told https://www.badcaps.net/forum/showthread.php?p=1108743 .To find the pinout you need the schematic.Comment

Re: mec 16xx dump with info block
Hello, password on T590. I have Vertyanov, read mec1663 epprom area 2kb and write edited bin with same FF inside. Now laptop show me messages like this. Invalid RFID Configuration Area etc. I can't enter to bios settings... Do you have mec 2kb bin without password?Comment

Re: mec 16xx dump with info block
P52 has mec1653, jtag pins are same as other thinkpads.
did put the pull up resistor for reset , but Vertyanov_JIG gives error.
did anyone managed to read the eprom from P52Attached FilesComment

Re: mec 16xx dump with info block
I was wondering if it was possible to use rt809h bga63 adapter to read/erase/write mec1663 offlineComment

Re: mec 16xx dump with info block
Assuming everything is OK, I suggest to take a look at motherboard schematic, check JTAG interface, you will see each signal has a PULL-UP resistor which are not populated in motherboard.
Now check the programmer to see if it has these PULL-UP resistors on JTAG signals.
You may have to add these PULL-UP resistors to motherboard JTAG signals for programmer to work… worth a try.Comment

Re: mec 16xx dump with info block
You don't need a resistor, just jump and read it, if you couldn't read it, you can extract the EC from the original file and then just flash the MEC16xx, nothing more than that. After the procedure you will have to write all the machine information such as the serial number of the machine board and a few more things. Some machines can't read the MEC16xx just write, I had this same experience on a T14 thinkpad, I discovered it after 3 weeks of attempts, so I just wrote it I used the same way I described it above and then I was successful.Last edited by 69d0b913; 04-09-2022, 03:03 PM.Comment

Re: mec 16xx dump with info block
Ok, going deeper in the rabbithole of lenovo Maintenance Utilities.))
My laptop is P14s gen1. EC Flashed with rt809f, no problem, same resistor for jtag reset and the same jtag pinout as showed earlier in the topic. Now we need to write serials back, and here is the problem!
Googling this problem lead me to this video https://www.youtube.com/watch?v=U30H3_iNM3k
I am using ThinkPad maintenance utilities 1.11(x64) blabla august.12.2020. First time I didnt have planar service option in the forst menu at all. Ok, I found two files - plnsrv.ini and tpconfig.ini with the utility. but plnsrv.ini doesnt have P14s entry for the model! Ok, notepad and lets add this entry manually. Copied two files on the flash drive in the same folder with boot64.efi and planar service option appeared. But anyway - i am introducing all info - c0, model, kb language, uuid, and after restart - the same 2202 Product name...
Now I am thinking that this utility is too outdated for the p14s... And it looks to me that I am out of options... Maybe somebody have any thoughts? Will be very gratefull....Comment

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:

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"? -
Hi everyone,
Iām looking for a 2 MB BIOS dump for a Lenovo IdeaPad 5 16ARH7H / Legion 5 with mainboard NM-E471 Rev. 2.0.
The BIOS chip is a Winbond W25Q16FW (1.8V, 2MB) and it's completely unresponsive / bricked. I tried recovery via USB but no success. Now I want to reflash it externally using a CH341A programmer.
I already found 32MB dumps (e.g. from Vinafix and Badcaps), but they are too large for the chip ā and the last 2MB in those files are just FF FF FF....
ā What I need:- A working 2MB BIOS dump
- Matching NM-E471 Rev. 2.0, e.g. JY575

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...
