RGH Question about creating a retail nand in jrunner

[bruno_rv]

Does making a retail nand with jrunner and flashing it to the nand increase ldv value or just flashing original downloaded firmware from xbox web or xbl does that?
Im asking because i have a non booting corona with red dot after 25-30 seconds with error code 0022,and i readed here that it can be also cause by wrong ldv or wrong nand backup. I I got one in that state,with original nand backup and cr rev c that stopped working after a month. No green dbg led anymore,no video/audio signal. I replaced cr,still the same problem. The guy cannot say what happened,and his son cannot confirm if he tried an update or similar.So i flashed original backup and got red dot. Increased ldv value with glitch nand ,again red dot. Then i tried making latest retail nand with jrunner,still red dot.
So i wanted to know if i can downgrade or something similar,or can i boot to xell with dgx even if LDV values are messed up. (Assuming that its not a hardware problem). I checked the soldering points,all look ok. I measured cpu_rst lines,all are ok.

RGH consoles don't belong on XBL, as far as the console quit working, you might want to provide pictures for better answers. Also break out your trusty multimeter to check for continuity as lead-free solder deteriorates across weak points over time(not in a month of course).

If all else fails, installing a DGX will enable you to get the cpukey and correct ldv.

Provided you have the CPU key, you don't need the DGX.

Read my LDV sticky.

Did you happen to read the nand that was on the box when you got it back (before you wrote back the backup)? Any changes?

 

[bruno_rv]

Thank you all for answers. Unfortunately i didnt read the nand,as i assumed that an rgh console with proper dashlaunch settings cannot go to xbl and be updated. After i wrote original nand back and was not working, the guy said maybe his son tried an update.Hm.

@Martin C

I read that sticky before making this thread but i didnt see if it is the same if i flash official fw from web and a jrunner made retail. A assume its the same thing.
I also see that more than 20 seconds can be wrong nand written or cpu/gpu problem.( i get about 28 seconds). I dont think that can be a wrong nand problem because they dont have the tools for nand writing. So maybe I should try a reflow? I dont think it can boot to xell because no cr glitches on this console.

"I dont think it can boot to xell because no cr glitches on this console."

Then you've damaged the CPU. You need to either ditch the board or replace the CPU.

 

[bruno_rv]

It came to me like that. As i said in the first post, it just stopped glitching after one month,as the guy told me. I just tried flashing nands.
What do you mean by "ditch"? Thank you.

I'm assuming that since you're not posting any images, everything on the board itself is perfect.

ditch = throw it away.

should ALWAYS read the nand before you start working on a console, gives you something to go back to...this should be standard practice (you have have got no idea what that person has done since they have got it)
and you are getting paid for this ????

Reflowed the cpu/gpu , soldered new kynar wire on postout pin (its a v3 corona) put new arctic silver paste and console is working now. Retail and glitch. It seems that the postout pin on the cpu was bad soldered or making short. Thank you all.
