So, prior to my stupidity, I made a system.img dump via dd

However, after my stupidity (tried flashing some lib files....), I am now stuck with only stock recovery mode, or download mode.

How can I flash back my system.img? I tried in download mode with heimdall... but it fails with

root@o7thDev:/media/MediaTwo/MyRom# heimdall flash --verbose --no-reboot --SYSTEM system.img
Heimdall v1.4.0

so I tried creating an update.zip that I could sideload flash in stock recovery, but that fails as well with

E: footer is wrong
E: signature verification failed

If I could get into adb shell, I'd be set... all I'd have to do is dd the system.img back (been there done that in SafeStrap), but when I try adb shell in stock recovery I just get "error: device not found", and in sideload mode, I get

error: closed

Please help? :crying:

  • Heimdall is not designed for flashing images backed up with dd. It's a tool for flashing specifically crafted firmware images. I would suggest flashing a custom recovery via Heimdall in download mode. – Chahk Jul 1 '14 at 17:23
  • As far as I know the only custom recovery I can have on this beast is SafeStrap 3.72, which was installed (but of course I can't even get that far). I'll see if I can find a Heimdall flashable version of it though... I'm on the NC1 locked bootloader... – Kevin Jul 1 '14 at 17:24
  • Is it possible for you to mount your dd image on a Linux PC and create an update.zip from the contents? – aureljared Apr 20 '15 at 0:35
  • Seems u need to use ODIN to get back your phone, You will lose all your data though – user52093 Jul 9 '15 at 5:57

Try disabling verification, via safestrap, and try both methods + Sideload again.

I should ask, why heimdall and safestrap? Use Clockworkmod recovery instead of safestrap and ODIN over heimdall. Yes, they require you to get your stuff online beforehand, but clockworkmod has got me out of a lot of soft-bricks

If I was boring, everyone I know would not bother with me :(

  • had no choice but to use safestrap on my AT&T S4 :), but I've since dumped it for a N900T anyways ;) – Kevin Jul 23 '15 at 13:16
