Root formatting system?

[New Rising]

I have never done this before flashing a rom, should i be? I've read that you should format your system in cwr before flashing a rom. I just do the usual wipe data/cache/dalvik in safestrap and have never had any problems. What does formatting do?

Thanks

Every developer states to format /system from the 'mounts & storage' section of recovery. If you choose to ignore this expert advice, please don't come back with complaints about the rom. Formatting /system clears out the existing operating system so that there are no remnants remaining when the new operating system is put into place.

Not every developer states to do this in there install instructions.

It's a good thing to do especially if the developer tells you to in there install instructions but I think most developers have the rom wipe system as part of the install. I always do it whenever I install a new rom just to be on the safe side.

I have done format system and reboot afterwards, but now my ZTE Blade just has initial logo on for a long time and does not start up. I think it was wrong to reboot (the package that I tried to load failed), but what can I do now? Thank you very much!

It really depends on the ROM. On the CM9 and AOKP builds from dhacker, you shouldn't wipe system. It has a special script that saves the GApps and restores them.

When you're going to a new ROM, you need to wipe nearly everything, including system, data, cache, dalvik.

But the problem right now is, that I cannot boot up my phone - it just shows the logo. Could you please tell me, how to get back in? (The ROM that I was unsuccessfully trying to use was CM9 - according to these instructions - http://www.modaco.com/topic/351670-ics-cm9-404-coldfusionx-for-the-zte-blade-rom-updated-2806/)

Thanks a lot, again

Easiest thing to do would be to restore a nandroid backup in safestrap or flash a different ROM.

Also, since you're using safestrap why not just toggle safe mode in CWM?

Did you flash the ROM from that page? Because that's for the Blade, not the Bionic.

He said he had a blade in his first post. He probably did a search just looking for help since he wiped his system and this thread came up in the search.

Jaanbi I don't know much about the Blade but your probably going to need some sort of recovery software (if ones available for the blade) if your phone won't boot and you can't get back into cwr.
Did you flash the ROM after you formatted system or did you just format and reboot?

Its ok, mine is a Blade - the user New Rising has a Bionic.

I cannot go to safestrap, is it possible, that I have installed that apk? When I turn on the phone and press "menu" button, the bootup logo stays displayed forever. If so, is there something further that can be done?

Kind regards,

If you are speaking of the Bionic try using Sanuri's House of Bionic software to restore the phone.
