Suggestions which FLASH programmer to buy...
Hello,
I need to buy a USB FLASH programmer to erase, program and test 4GB (32Gbx1) K9GAG08U0E-PCB0 TSOP48 NAND FLASH chips and 512KB (4Mbx1) MX25L4006EM1I-12G serial FLASH 8pin SOP chips. Most of all I need comprehensive testing of these chips so I can manage which ones are bad. I have hundreds of these chips removed from bad tablet mainboards...
I found this cheap programmer on ebay:
http://www.ebay.com/itm/171341819315...%3AMEBIDX%3AIT
What do you think of it? Is this programmer and it's software capable of testing/programming my chips, especially 4GB NAND flash TSOP48??
Any help and suggestion is more than welcome.
Thanks!
Cheers,

Following this guide (https://www.reddit.com/r/thinkpad/co...g_and_flashing) i re-flashed my t480s BIOS using an external (CH341A) programmer. The flash didnt work, so i reverted back to my BIOS backup successfully. The BIOS in the chip and the BIOS backup file are identical according to windows' file compare. The revert, however, didnt work: the only thing the computer does is flash the power button 3 times when AC power is connected. I've tried unplugging the CMOS battery, holding the reset button and holding down the power button- no signs of life.... -
I'm looking to upgrade several 8GB 820-00850 boards to 16GB or 32GB for personal use. I am curious what the best practice and process is for sourcing new replacement chips, and what vendor(s) you guys prefer? Another question is, how do I find compatible chips and their corresponding part/model numbers? For example, in the 820-00850 schematic, the DDR chip U2600 model listed (EDFB232A1MA) corresponds to 1x32GB chip. Of course, I would need 4x8GB chips to replace the 4x2GB chips currently on the board. How do I find compatible 8GB chips? Is it as simple as searching "BGA178 8GB 2133"... -
Hi all,
I’m trying to recover a Lenovo Yoga Slim 7-14ARE05 with board DA0LS3MBAF0 Rev:F. I’ve run into an unusual issue where USB-C PD is stuck at 4.7–5V and the system won’t boot (keyboard lights flash briefly, then nothing).
🔥 The Problem Started After Suspected ESD/PD Fault
I experienced a power issue or ESD event through a USB-C charger
After that, the NX20P5090 power switch was visibly burned and was replaced
Now the PD controller always negotiates 5V @ 2A, even with known-good chargers
🧠 What I’ve Done So Far

Hello, I'm stuck in troubleshooting…
The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.
In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
When I press the flash button, it's detected by the system, flash icon appear on LDC display.... -
Hi, everyone!
I've recently acquired two brand new SPI chips to replace the one currently in my Acer A514-54G laptop MB (FH5AT LA-K092P). The reason why I'm replacing the current SPI chip is because I had some difficulties with a third-party IT assistant who pretty much lacked the soldering skills and ended up destroying the current SPI chip soldered to my MB from factory.
I've decided to do this on my own because I spent the past month or so learning some soldering skills and BIOS modding through Badcaps and WinRaid forums, hence the attempt. I've also chosen to buy...
