[Q] Cyanogenmod (official) OTA update failing - root possibly lost?

Hi

I've been prompted in the last few days to install an OTA cyanogenmod update.

When I accept the installation, the phone reboots.

About 1/5 of the way through the progressbar, the installation halts and I come to a screen headed "Root access possibly lost. Fix? THIS CANNOT BE UNDONE".

Various 'no' options, then 'yes - fix root (/system/xbin/su). Regardless of whether I select yes/no, the installation seems to fail and I reboot into my current version.

Lower on the screen, after the heading "Installing update...." is the error code "assert failred: apply_patch_check("/system/xbin/su", [hexcodes], [hexcodes]) E:Error in /cache/cm-maguro-[hex]-signed-1.zip" (Status 7) Installation aborted.

Any views as to how I can get past this and get the update installed?

Many thanks

i have a similar problem with the latest CM update. it goes into recovery to do the update and fails, but it immediately reboots the phone into the old version, so i am unable to see the error message.

does anyone know where the error log of the cm recovery is located?

i fixed it by doing the following:

- go into recovery mode (shutdown, then press vol-up, vol-down and power, press vol-up (to select recovery), press power)
- wipe cache partition
- wipe dalvik cache (under advanced)
- reboot

it then downloads the update again and this time it worked

I'm using omnimetal rom, but also come across with the root access may be lost problem. Every time after I flashing a new kernel in cwm, and pressed reboot the system, the message pops up. I choose "yes,fix it" every time. But the message still exist. I clear cache and dalvik cache when I flash a new kernel. So, clearing cache and dalvik cache does not fix the root access problem.

could you elaborate how you did it? when did you go into recovery mode? before CM installer? or after when it's done asking if you want to fix root?

I did it twice. I said Yes, fix root. Didn't work. So I didn't fix root second time. Didn't work also.
