[Q] How to format /system without Custom Recovery?? - Galaxy S III Q&A, Help & Troubleshooting

Hi there,
Now my device has the ELLA rom flashed (anyway, I'm thinking about flash the recent ELLC spanish rom)
I have rooted by CF-Root (not CF Auto root) so my counter is not zero , and the red mark is there.
I want to be "official" so my idea is not to flash a custom recovery.
I am going to use Triangle Away and to flash again the Rom with Odin.
Then I will root with CF-Autoroot.
Now, here is my problem: how to make the things that I made with a Custom Recovery, without a Custom Recovery.
- Flash .zip files -> I think I can use Mobile Odin
- Backup / restore -> Maybe Titanium Backup would help
- Wipe Data and wipe Cache -> Stock recovery is ok for this.
- Wipe Dalvik and format /system -> Any suggestions??
I am thinking about non-permanent custom recoveries, or even in a Custom Recovery that does not increase the counter...does it exist?
Many thanks for your help!!

Stock recovery can't replace a custom one.
You can't flash zips with Odin. AFAIK you can't wipe cache from stock recovery.
The only way to have the counter at zero is not to change anything

I thought that stock recovery allows to wipe data and wipe cache (cache , not dalvik)
Then .. Is there NO way to format /system without change stock recovery?
Thanks

Why do you need to wipe system?

Yeah, a data wipe is basically a system format.
Aside that, there is no such thing as a system wipe unless you want to delete your efs and all important files.

I think it is the best way to have a really clean Rom, without stuff from the oldest rom.
When I dont format /system sometimes I can find apps and stuff from the oldest rom, so I think that the new rom is not really fresh.
Thank you

Data wipe does not format /system
And formatting /system does not wipe Efs ...

You can't wipe system from stock recovery. Here's your answer

The solution would be to wipe /system from CWM, then flash flash a stock ROM with stock recovery

Yes, I am pretty sure. It is not possible from stock recovery.
But I was wondering if I can format /system with an alternative method like ADB, non permanent recovery, etc.
Thanks , and please excuse me if I am stubborn

Best way to flash back to stock rom?

What would be the best way to go from any custom rom back to a stock rom. Wipe data, cache, dalvik cache in recovery, the shut down phone and flash stock rom via odin? Or should I also wipe system before flashing?
Thanks!

You don't need to do any wipes through CWM if you are going to be flashing a stock Odin rom, odin automatically takes care of all that stuff. You can just boot your phone into download mode as is and flash the odin rom.

Btw, your title is a bit misleading/ confusing? Aha, you ask "best way to flash back to custom rom" ??
Yes that was indeed a bit misleading, corrected!

[Q] How to remove a ROM so I can flash with a different ROM?

I flashed my S2 yesterday with CheckROM and I like it and everything but I'd like to try MIUI today but I'm not sure how I would go about this? I think I may have to wipe my phone (already have a backup from before I flashed with CheckROM) and then just install MIUI like I did CheckROM? Correct me if there is another way or I'm wrong.
Just go into clock work recovery, wipe data cache, flash miui.

By formats system do you mean wipes everything or just cache?
Let's see.......
You wipe data, cache but your phone can boot, because the OS remains.
You wipe system OS got removed, you can't boot phone.
Wiping system is the cleanest flash you can do.

[Q] How to make a clean install?

I wanted to flash a new ROM by wiping everything. But since I dont have an ext sd card I can't use the scripts provided here because it would end up deleting the other ROM I want to flash.

If I am not wrong, you can also use mega wipe (the script your mentioned I guess) with Odin and flash your ROM that way.
Simple Mounts and Storage.
Format cache system data sdcard preload = empty phone zero left .
Requires boot to download mode and flash rom.

Ahh but correct me if I'm wrong, wouldn't just flashing with Odin remove all the files and since the ROM I have downloaded i.e Omega Rom, would be in the .zip format right? But Odin only recoginses the .tar format. How do I go about it?

I typically delete cache, dalvik cache and format system, you can try to keep (user) data, but I experienced problem with once...
If you using custom roms with gapps, dont forget to flash again gapps after the rom...

I think better to use odin if you want to flash stock rom, oherwise is suggest using custom recovery and delete system / data cache what you actually need. then flash the new rom from zip.
For example: i using AOKP and always flashing from csutom recovery, but the baseband version stays the old that i used previously on stock samsung rom, even if i delete system and cache and datas...

No, see the thing is that i'm having weird issues with my phone and i want to start afresh but with omega ROM. This is the reason I want to wipe everything off my phone including the user data.

I suggest to revert back to stock samsung from ODIN, then put a custom recovery via odin, and from your custom recovery: delete system, cache, dalvik cache, userdata. Then flash omega and gapps if you need from sdcard.. I think people mostly doing the same.
If you go back to stock samsung, all teh modem version will be stock.
sorry if I dont have right. I did never tried Omega, but with aokp the same was working good to me.

Sorry, its may bad, I jsut see now you cant use SD card. Dont worry: Once you have stock via Odin, nothing can make harm for the next Custom Rom (Omega)

Then follow my instructions and flash stock rom then root then custom rom .
OR do not format SDCARD and flash zip from sdcard BUT its not a 100% clean wipe .

Sorry I don't know about conversion between those two, but Im not sure if you really wipe "everything" you will have modem/radio drivers in omega. I think in aokp we don't have.. So I always have the last modem version that I used with stock samsung rom, no matters which another rom I using...
May I ask what kind of issues you have? Why do you want completely wipe your device?

Yes but to convert a custom zip to a flashable tar is not just convert .
Images need to be built boot.img cache.img hidden.img recovery .img system .img
100% the correct files otherwise 100% brick .

1 Stock ROM from ODIN: depends on in which ROM you are, you you are in any other tom than official than you need to wipe after flashing else you will be stuck in bootloop
2 Stock ROM from ODIN with PIT repartition: wipes everything because you are re-partitioning the internal memory.
3 Wipe Data/Cache: will wipe you data and cache both
4 Custom Recovery (CWM/TWRP?) if you mean flashing custom recovery than the answer is no, it won't wipe anything..
5 Custom Kernel: It too wont wipe anything..
I hope you have got all of your answers..

Depends if u are on stock or custom recovery. The stock recovery will delete everything. Custom recoveries will not delete ur music, dcim, pictures, download folders.

Thats strange, did you flash anything else with the ROM ? Any mods etc ?
Are you sure your data, cache & system partitions are in ext4 filesystems ?
earlier i flashed blu spark kernel and converted data and cache to f2fs.
but now i installed stock recovery and flashed only stock rom nothing else.

Can you post screenshots of your data, system & cache being ext4 ?
Also, when you're flashing this ROM, dont flash anything else, Nothing at all, only this 800MB zip package.
Edit - Use TWRP for all this.
