I got problem when I flashed my ps3 and turn on it beeps twice then Turn off automatically.
I am using TEENSY++2.0 NANDway Guide. using PS3 Downgrade Tool v1.3
to clarify my setup :

i am using Teensy ++2.0 with tsop48 and off board chip the mobo is COK-002 and Flash0 is near to cpu/gpu and the other is Flash1(just to make sure)

i have dumped both nands and checked with every PS3 Dump Checker and everything seems to be working nothing wrong with my dumps.I patched with nor patcher 4.78 used for 3.55,and also for the latest CFW /
I double checked my solder pins everything seems to be ok

I just want does this problem occur due bad solder pins or due to patching process? I have done with more than ps3s and same thing
Thanks
 
i did try that flashing back the original dump again same thing .

i have tried so far 4 ps3 with the same results not sure it is my patching process or its the way i solder but i checked all solders nothing wrong with it .
 
I have no experience with NAND downgrading, maybe [MENTION=29]Joonie[/MENTION] or [MENTION=48]littlebalup[/MENTION] can help here. But because of not working original dump is probably soldering or hardware issue. But wait for other answers.

Validating flash dumps - PS3 Developer wiki

If you've already broken FOUR ps3's by flashing them incorrectly, PLEASE STOP DESTROYING CONSOLES!!!!
Included is a link to validating flash dumps, i'd read it over, watch a few more youtube videos, something...
whatever you are doing is NOT working.

At this point, i'd recommend a NAND flashing service on ebay or through one of the console mod sites, someone trustworthy of course.
Have a nice day! :)

1. Try dumping the whole nand dump after flashing, and compare the dumps with what you flashed, if they match 100%, then you have a hardware issue unless your dump was corrupted [which I doubt]

Yes diffwrite often malfunction and corrupts DATA when power feeding is instable.

Ohh OK well power is stable but do you think i should wirte the whole flash instead of diffwrite ?
 
Thanks dude i will try to dump again and compare it to the flash that i patched .

and another question by looking to my screen shot above do you think that is a bad dump ? because according to PS3 Dump Checker the flash is OK ?

yea i already checked that and here is the screen shots :

for Flash0:attached screen

but for Flash1 i got ecc error :

Code: 
Bad Blocks
----------
None found!

ECC Errors
----------
Offset: 0x015DEC80 (Block: 169 / 0x0A9)
Offset: 0x0277C500 (Block: 306 / 0x132)
Offset: 0x0277C700 (Block: 306 / 0x132)
Offset: 0x0277C900 (Block: 306 / 0x132)
Offset: 0x0277CB00 (Block: 306 / 0x132)

thats mean my nand dumps were bad right ? so in this case i may need to check for ecc errors on my other consoles that i have dumped

this checks were before patches .

ok so far 3 consoles one of them are no bad block or ecc error checked with norpatcher latest version 4.78.1

i will process with the other working console.

and is there anyway to fix those ecc error with the other two consoles ?
 
Edited :i have dumped the flashed one and compare it to the flashed i have written and they are not identical.?

then what caused this error ? it is the patching process ? if yes what is your recommended software for downgrading like FlowRebuilder 5 or Playstation 3 Downgrade Tool v4.0 ? because when i patch the nands with those software and compare them they are not identical is that a software issue ? for Playstation 3 Downgrade tool i use Automatic patch the nands .

in my case, if I get 1-2 bad ecc on my E01, I always get YLOD...

Some modders have experienced where they had BAD ECC still the system was able to downgrade and boot, but in your case, that maybe the problem..
 
well [MENTION=29]Joonie[/MENTION] i have no errors with the ecc anymore my dumps are fine but i think its the patching process i get it wrong because when i use two different software for patching like flowrebuilder and PS3 PlayStation 3 Flash Tool v4.0 Public Release i dont get identical patches (using Automatic patch raw nand flash using PlayStation 3 Flash Tool v4.0 Public Release) , but only if i used PlayStation 3 Flash Tool v4.0 Public Release Unscramble and then Scramble i get identical flashes compared to other software (Flowrebuilder).

and what if you i send my dumps you can verify and patch them for me if you dont mind .
