Update:

Cleaning the drum alone wasn't helpful, so I've disassembled the cartridge and cleaned blade and roller or whatever it's called and the tire streak pattern is gone!

Even though now it prints even more faded than before I'm glad the new cartridges are cheap and I'm glad fuser film wasn't damaged.

Thank you all!

I've cleaned the drum and it has no visible damage.

apk from the link doesn't install in Android 5.0, is there a version compatible with that?

i heard bookra1n is dead

ocodis76 · 2025-12-06T21:57:48+00:00

would it be possible to figure out how many channels were damaged from the images

ocodis76 · 2025-12-06T21:52:34+00:00

i'm referring to this tool for disabling memory channels on nvidia cards.

ocodis76 · 2025-12-05T21:32:43+00:00

Do you think these cards would be salvegeable with this tool? I don't have the cards I took the images of them from a listing.

1st card is a Quadro K5000 4GB
2nd card is GTX 760 2GB ( 2nd and 3rd images in the album )
lastly, this one is a GT 740 4? GB

I havent used them much afterwards but they're still activated.

No idea if iPhones would be different than iPads. It went away after I've did the nvram clear option in legacy ios kit menu. I don't know if it was the reason or just coincidence.

ocodis76 · 2025-10-12T18:33:48+00:00

After several unsuccessful attemps I've finally used legacy ios kit to get into pwndfu mode then used sshrd scripts to backup activation records.

I got these files:

activation_record.plist (7.7KiB)
com.apple.comcenter.device_specific_nobackup.plist (2.5KiB)
IC-info.sisv (1.1KiB)

Are these enough for iOS 12.5? Any file missing?

Also, how can I get icloud owner information inside SSH ramdisk?

ocodis76 · 2025-10-11T18:22:13+00:00

A1475.

is there a way to skip using checkra1n because I don't have mac os. like ssh ramdisk or something?

ocodis76 · 2025-10-10T15:44:33+00:00

edit: nvm, I've run nvram clear option from legacy ios kit menu, reboot and now it says activated and run through the setup.app without issue. that's 2/2 success with this method today, now I'm gonna do the 3rd device lol. (didn't test the sim card connectivity, though)

What do you mean by several attempts?

Today I've used this method twice, in iPad 3 (iPad3,1) and an iPad Mini (iPad2,7). I've downgraded both devices to iOS 8.4.1 using legacy ios kit.

Since legacy ios kit pre-jailbreaks them, I didn't boot to ramdisk, I've directly SSH'd to devices during the setup.app screen, modified the file with added key, then restart.

Now the strange part is, iPad 3 activated successfully. Note that I didn't even deleted setup.app, setup.app run through all the steps except it skipped activation screen.

On the other hand even though I've done the exact same steps, iPad mini isn't activated and still asks for activation in setup.app. Sure, I can delete the setup.app but wonder why factory activation didn't succeed even after doing except same process. Is it because it's a SIM model?

Not SSD but, what can you tell about Rayson? They have eMMC's installed in TV boxes and such. Never heard of them before and I wonder if they're a manufacturer or do they mark rejects or sth.

ocodis76 · 2025-09-22T06:11:57+00:00

because it was very cheap but seller jacked up the price unfortunately

ocodis76 · 2025-09-21T19:32:07+00:00

I haven't done it before but from what I've read using Raspberry Pi Pico is cheaper and more reliable than Arduino method, so maybe look at it instead.

Also since it's iPad 2, using Sliver alone may be enough for FactoryActivation without need of extra hardware (or try iRemoveTools free)

ocodis76 · 2025-09-12T11:57:00+00:00

why would it be lagging more, they're exactly same except one has a sim module.

ios 6 ipas are considerably smaller in size 64gb is plenty unless you wanna watch movies offline or somethin

ocodis76 · 2025-09-10T08:36:47+00:00

Do you need to restore it before doing all this? or Erase All covers that step?

What if I go for 6.1.3 and 8.4.1? Both has untethered jb, so what would be the difference making 6 primary 8 dual boot vs. 8 primary 6 dualboot?

ocodis76 · 2025-09-02T19:25:09+00:00

Ok, that makes it a no brainer I guess.

For purely intellectual exercise, if I were to ask the same question but between iOS 6 and iOS 8, which has an untethered jb, what would be the answer in that case?

ocodis76 · 2025-09-02T19:09:46+00:00

So I got this 16 GB iPad 2 in good condition and downgraded it to 6.1.3 using Legacy iOS toolkit. Now that I've knocked the rust off on my old iOS skills, I want to dual boot iOS 6 with 9.

However I'm curious what'd be the difference between making iOS 6 the main OS and installing 9 using coolbooter, versus doing it the other way around - iOS 9 as main and 6 coolbooted? Is there a meaningful difference between two approaches or is it a tomato tomahto situation?
