ANSWERED RGH- RROD 0022 problem

[Martin C]

if you want to be 100% sure about the size of the NAND, read the HYNIX number off the NAND and look it up.

If you really did have a BB Jasper and only dumped 16MB, you wouldn't be able to open the NAND in 360 Flash Dump Tool.


Does your LDV in XeLL match that of your created image?

well..i just checked
HY27US08281A
[FONT=Arial, Helvetica]"The HYNIX HY27US08281A series is a 16Mx8bit with spare 4M bit capacity.[/FONT][FONT=Arial, Helvetica]The device contains 1024 ([/FONT][FONT=Arial, Helvetica]16Kbyte)[/FONT][FONT=Arial, Helvetica] blocks, composed by 32 pages consisting in two NAND structures of 16 series connected Flash cells."
so it's 100% 16 jasper but it has BB controller..right ?

and yes both LDV are 8..as the pic
and thanx martin as usual


oh..btw...the pll bypass to GND resistance measure 9.6K when no power and reduced to almost 6K when power cable connected

Yep, it's 16MB

So try this:

Make a retail NAND from your current dump and CPU key. Then use this as the base NAND for your glitch image.

well..i give up
i think this is one @#$ box that refuse to glitch in an operable way
before i try MARTIN C last's advice isaid let's try it another time ( it has been powered of for a long time now since i was busy to do anything with it) and guess what...it worked from the first glitch !!!!!
i powered it down..and tried it again...and it worked again almost first time also
so...soldering is fine and the hacked image has no problem
then one more and u know what...no go ( I didn't even move a muscle) no re-routing ..no nothing
tried long-short. cpu_rst wires
tried inline capacitor for cpu_rst wire...still no way to boot again
i tried the alt. 3.3V...it booted once then no way in 15 times
so i wrote the original nand and it's working now...
i will leave it this way till someone finds out what is wrong with some jaspers
thanx for everyone who tried to help..
and big thanx to Martin C for his dedication
i hoped to be one of ur success threads

mine had a long silver screw pinching the green cable
