Hi Guys i have a few question on Flashing. I have been reading a lot from this site but i still have a few doubts before i can flash without question.
I own a I9100G and i flashed supermatos kernel using Odian as a result i got CWM, using recovery mode of this cwm i installed super Rom (http://forum.xda-developers.com/showthread.php?t=1374135) (zip) from sd card.
My questions
1)If now i wnt to go back to a completely stock ROM do i need to use Odian only or i can use CWM?
2)Flashing custom ROM using CWM do i always need to wipe data/factory reset and in mount & storage always select format /system partision?
3)Once during flashing I did make a backup using CWM and wanted to flash a new Custom ROM so i wipe data/factory reset and also chose format/system partision and when i went to chose the zip from sd card to my surprise neither was the zip there nor was my previous backup. why did this happen?
I knw they are a lot of noob questions but i need to clear them to flash more comfortably

ODIN
2)Flashing custom ROM using CWM do i always need to wipe data/factory reset and in mount & storage always select format /system partision?
No just follow the roms instructions
3)Once during flashing I did make a backup using CWM and wanted to flash a new Custom ROM so i wipe data/factory reset and also chose format/system partision and when i went to chose the zip from sd card to my surprise neither was the zip there nor was my previous backup. why did this happen?
You formatted the sd card .
You can always copy the clockwork mod folder to your external sd card or PC .

Thanks a lot for the answers. i just have one last doubt in what cases do we
1) wipe data factory reset
2)wipe cache partition
3)mount storage partision ( in this the formating option)
I read in a few threads tat we need to wipe data/factory reset for complete instalation of Custom ROM is this true?

Thanks for the info. Also i did a search and i guess more or less i now have better clarity
Hi
When you want to do a clean install of Windows OS, you all know that the right way to go is to format the primary partition first..
I was wondering: why can't we do the "same" in Android?
I've noticed that in CWM recovery there are many format options in addition to just doing Wipes...
So what if instead of doing the old Wipe data/cache and factory reset before flashing new rom, especially when migrating from Sammy to AOSP, we use the FORMAT function of the CWM recovery console?
So this bring up my new line of questions:
Which Formats are safe (as in terms of not bricking only, since we all know that we must backup first)?
Is Format data safe and recommended before flashing?
Is Format system safe and recommended before flashing?
Is Format SD card safe and recommended before flashing?
Does Format system erases the entire OS, meaning the ROM with it's kernel? If kernel is wiped does it mean that CWM will be lost upon next boot?
Same goes for Format SDCARD. Will this erase the entire internal memory? So the new ROM.ZIP should be placed in the external SD first?
I'd really appreciate if someone could answer all of the above questions
Many thanks

If you don't have bad chip then all are safe. If you have bad chip then make sure you have safe kernel.
General steps before flashing a new ROM.
1. Backup your present ROM just incase
1. Wipe data/ factory reset
2. Wipe cache partition
3. Wipe dalvik cache (under advanced)
4. Format /system (under mount)
5. Flash your desired Rom/zips
6. Fix permissions (under advanced)
Notes:
- If you are moving from from an AOSP ROM to Samsung (vice versa), perform all the steps above.
- If you are upgrading / downgrading from one android version to another e.g ICS to jellybean or 4.0.3 to 4.0.4, also perform all the steps above.
- If you are upgrading from a Samsung ROM to another wipe the same android version, you may skip step 1.
- if you are upgrading your Aosp/aokp Rom with another with the same android version e.g 4.0.4 Aosp to 4.0.4 aokp, you may also skip step 1.
*******Important******
If you are presently running a Samsung based 4.0.4 Rom that is using Samsung based kernel e.g CF-ROOT or stock kernel, please flash Siyah kernel before performing any of the above steps. You will end up with ash unusable device if you don't adhere to this important information.

Just 2 more questions:
1. what about format Format SDcard (internal)? Is it also safe/recommended? What does it do exactly?
2. can any of the the above formats delete the IMIE? Where i it stored? On internal SDcard? Will formatting it delete it?
Thanks

Formatting the Internal Sd card wipes all your data (music, photos, videos) on the internal memory of the phone.
Doing all those wipes doesnt affect the IMEI as far as I know...

1. You're first question has been answered in the post before mine.
2. About IMEI:
-Your IMEI is stored in your root folder /efs inn your system reserved partition.
-Flashing Roms and kernel shouldn't mess with this folder but sometimes it happens.
-most of the Roms Agnes kernels made by recognized developers will backup your efs folder before flashing.
-too be on a safer side though, you can visit the thread below to backup your efs (imei) folder yourself before messing with your phone.

My problem is that I keep thinking in MS Windows terms.. I was sure that "Format SDCARD" is the parallel to formatting the entire "Hard drive", just like to delete the system partition..
Know let me see if I got everything right:
Format system is like deleting the Windows folder - no more OS (ROM)
Format data is like deleting all user account = deleting the "Programs data" folder in Windows - no more app data
Formatting SDCARD is like deleting the "Users" folder including "my documents" - no more user private data
So by using the 3 above formats, there is no need to do a Factory reset. But what about Wipe cache and Dalvik? shouldn't System format take care of those two caches? Or perhaps Cache and Dalvik are to separate partitions?
And for the few last question, so I can finally declare myself an Android expert :
(1) Format boot is a very bad idea right? It will delete the bootloader, meaning one must flash a rom that includes one of it's own?
(2) Are all roms intended for CWM flashing come with their own boot partition?
(3) So if Format boot is risky, I can conclude that the CWM recovery must be part of the boot partition right?
Many thanks for all the help. Once I get all of this right, I will feel confidant to start flashing roms on my own for the first time (I already got my phone rooted and CWMed by flashing Siyah kernel using Odin

1) As far as I know, the boot partition is reserved for kernel. So, if you format it, phone won't be able to boot further than the initial Sgs2 logo. But it will still be flashable in Download mode.
2) If kernel is a part of boot partition, and most roms come with their own kernels, the you could say that the come with their own boot data.
3) If you format boot, you will also loose Cwm as it is a part of the kernel. Download mode would be still accessible as it is a part of the (secondary) bootloader which can be only overriden with Odin.
But again, I'm not 100% sure about this.

You saved a noob a whole lot of troble:cyclops:
I want to erase all my previous data in internal storage. More specifically, erase the OS and data (app data, user data, media, etc), then I'm gonna flash new ROM.
But of course, I don't want to erase boot system and recovery system.
1. Can I do above by using CWM - Mounts : format /sdcard ?
2. Does format /sdcard include format /system, /data, /cache, and wipe dalvik cache?
3. Is format /sdcard safe to do?
The answer !!!

Now we know what to wipe or format (and what to not format)

To install a new rom, you don't have to wipe the internal sdcard, just wipe data & cache and navigate to advanced and wipe dalvik cache, and then to mount and format system, then flash your rom, or use TWRP it's easier, press wipe then advanced wipe and mark (data, cache, dalvik cache, system) and swipe to wipe, then flash your rom.
Ps: all app data is removed from internal storage (data in sdcard\android) when you wipe data, so you don't have to wipe internal storage

2.Flash the Kernel in FastBoot and reboot into CWM Recovery.
Then follow the below Steps
*make sure you've the downloaded rom on your sd card
*always do a full CWM backup of your current rom
*reboot into recovery
*wipe data/factory reset, wipe cache partition, wipe dalvik cache & wipe battery stats
*mount & storage > mount data & system (it will change from "mount /data" to "unmount /data")
*format cache, data & system
*install custom zip > choose the main rom
*reboot into phone, skip setup (next, next & next)
*reboot the phone again
*for neo user only: flash the patch in -=codename_ei8ht_final=- folder
*hit the 'thanks' button

Just to confirm, you did a factory reset after flashing, right?

YES
and a full format and wipe because you are coming from a different rom?
From the neatrom thread
1- Copy all the files that you want to save to an sdcard or a computer;
2- Reboot phone into recovery;
3- Go to Mounts and Mass Storage;
4 - Format /emmc;
5- Install NeatRom;
6- Enjoy this fine ROM with a clean install;
- format /sdcard
- format /sd-ext
- format /cache
- format /system
- format /data
- format /preload
- format /emmc
This will stop and corruption from previous roms

I even flashed a clean ICS with APBOOT file and repartitioned it like new.. And no I didnt wipe Emmc, it's a memory card how could it affect anything.
I have the towers connection now, and experienced a new weird thing..:
Phone can't go Idle.. It just fakes it and turns screen blank.. Even if I put a password it doesn't apply it when turning screen on, not even slide!

For a start you shouldn't be repartitioning anything. That was a bit silly.

Emmc is not a memory card as such....it is one of the phones memory partitions......
If a dev says 'wipe it' he aint just blowin smoke out of his a**

Lol seriously? So I wipe the SD card and everything??? From where do I install the Rom then!! I wouldn\t have it in my memory no more!
Lol,not only should you read the 1st post in a rom thread,you should be reading the next 2000+ posts after it,and the 3000+ posts from the discussion thread;if there is one.
Then you can see any issues others have.
Lol
Anyways I tried EVERYTHING and still have this problem

Go into recovery and format system, data,preload,cache, and dalvik cache in advanced. Flash you're rom/gapps from int sd and reboot. Also have a copy of the rom/gapps on you're ext sd too. Have you lost any memory?
Hi mates i made a flashable.zip for CWM recovery based of the ISR/ISRAEL V20A firmware
It has all the same things of the KDZ file i just extracted a rooted it.
INSTALLATION:
MAKE A NANDROID BACKUP OF YOUR CURRENT ROM AND APPS,RECOVERY,TITANIUM BACKUP ETC
Go into CWM recovery
then go to :
Mounts and Storage
mount /data
mount /sdcard
mount /system
under that options select this ones:
format /cache
format /data
format /system
go back to the main menu
then wipe Cache partition
after that go to advanced and wipe dalvik cache
go back to main menu then
wipe data/factory reset
Install Rom from SDCARD
after installation its completed wipe cache and dalvik cache again
Restart the phone.
Go to superSU app
it will show a warning telling you that something its wrong with the SU access.
Reboot into CWM and flash the SuperSU providen by chainfire.
http://download.chainfire.eu/396/SuperSU/
Reboot the phone then superSU app should be gone from the app drawer,just reinstall it from google play and update the binaries via normal mode.
Reboot the phone again ,now you wil have complete root access
