[Q] Low level format internal memory

---

For some reason my flexrom partition got corrupted and I would like to low level format, a normal format in cwm can't repair it. Currently I can only install rom that do not touch flexrom. Is this even possible? Any help would be greatly appreciated.

If you have your cuid number, you can go to the ics recovery thread, and nvflash the patched ics boot loader and recovery. I believe this will format all partitions and wipe the tablet clean leaving only the ics patched boot loader and cwm recovery.

Had to do it on mine yesterday as the leaked 501 updates fubarred all internal memory. No biggie.

Thanks for replying again moscow, I tried this method:

I think that's the one you were talking about. I don't know why but my tab doesn't wake in "download mode" as specified. I do put it in apx with the reset/power combination but nothing happen when I enter my sbk. Strangely I can use apx with timmydean's 3.2.1 EEUs tool without problem but I can't with nflash...I succesfuly used nflash before to patch the bootloader and flash cwm when I tried the leak back then but it doesn't work anymore.

Something other than flexrom must be wrong...cmw always give me an error when formating flexrom though. At least the ICS rom that shall not be named work fine at least. As I said in my other thread, all leak based rom fail to boot...even the new cm9, probably because it use stock ics kernel. I hope the official ota update will fix it, but I doubt it because even the update.zip with stock recovery failed to boot. Thanks again for your assistance Moscow!

Well, when I fubarred my blocks, it took me a couple times till I figured out to nvflash from a normal windows cmd window, and not through adb!

Also, although my cuid numbers are different, they output the same sequence through vach's site.

Have you toggled data/media in cwm to completely format the tab?

Still I would try the nvflash for the patched boot loader. That should wipe that puppy clean.

Ok I finally got it to enter download mode (I had some missing files) and start the flashing procedure but again with errors. I removed the CLS from the run.bat, so here is the ouput:

Generate your SBK with your CPUID from here : http://vache-android.com/v1/index.

Enter your SBK:0x97D71E00 0xD423C006 0x3B6A2404 0x027A2103

So if im right partition 4 is bootloader, hope that helps..Thanks!

I don't know. But clearly something is amiss. When you converted your UID on Vache's site, the new ICS UID converted number, should have been the same as your original UID number. Can you verify? (the 2 UID numbers have the same output)

Example;
0x038061c7409fa617 (HC)

0x79531F00 0xBB680C01 0xFB22E803 0x8ADE2003

38061c7409fa617 (ICS)

0x79531F00 0xBB680C01 0xFB22E803 0x8ADE2003

For some reason, mine stayed the same.

Best bet, run this by Drellisdee on his RA Recovery thread. He;s the master of this, and maybe he has some insight.
