[Q] Wiping methods - Galaxy S I9000 Q&A, Help & Troubleshooting

Hello,
I am flashing a lot of ROMs lately and is there any real difference between these 2 methods:
1) Go to recovery - mounts and storage
format /system, /data, /cache, /sdcard
then flash a new ROM through CWM recovery
and
2) Do the things above (format /system, /data, /cache, /sdcard)
flash a stock ROM via heimdall/odin
flash a CWM compatible kernel
wipe everything again
flash the new CWM ROM
?
Thank you in advance!

I don't see any difference between those methods, just that some rom's require to be on a specific firmware ( JVQ, JVP etc ) in order to flash that rom.
And for the second metond I don't see the point of wiping before flashing a stock rom because if u flash via odin with repartition ticked this will automatically wipe everything .

Converting to ext3

Hello guys, im using cm7 kang build at the moment and i want to try the stock based roms like modaco rom. I understand that i have to convert to ext3 by flashing a zip file called backtoext3, but there are no proper instructions of how to do this, so please correct me if im wrong
1. boot into recovery
2. wipe data
3. wipe cache
4. wipe dalvik cache
5. wipe battery stats
6. flash backtoext3.zip file in clockwork
7. flash rom in clockwork
This should be correct...
No need to wipe

[Q] flash ICs custom rom from GB

I flashed GB rom KJ1 via PC Odin. Everything is fine except the key board saying null null. But that is ok beacuse I am not going stay in GB but planning to flash kingdoird 4.1.1. When I go to recovrey mode I can see all the options, such as wipe data and cashe. Also in advanced option wipe Dalvik cache and mountunt and storage format /cache,format /system,format /data and also the ROM KD 4.1.1 in external SD card. Therefore my question is since all option are avaiable to me in recovery mode and I am in GB rom, can proceed to flash the custom ICS rom, KD v4.1.1. Thanks
.
Custom ROMs usually require root access as well as the option to install a ZIP file from SD card/internal memory. Do you see such option as well? If not, you probably need to download a matching rooted kernel with CMW recovery console pre-installed. See here for a list, choose the one matching KJ1.

I can see the option Install zip from sd card and the rom file in sd card. The Recovery mod is CWM based recovery V5.0.2.7

No problem at all, you can do it but it isn't necessary, you can flash root file, then cwm 5.0.2.6. FIX or you can flash cf-root kernel to get both in one shot
I recommend you do 3 wipes before flash a custom rom and after too to get the cleanest rom as posible (e.g. If you get bootlop, some custom Rom not need it, or you'll get FC, anyway YOU ALWAYS READ THE DEVELOPER INSTRUCCTION TO INSTALL A CUSTOM ROM)
Even if you can restore a backup, do 3 wipes before restoring and then restore it (to avoid boot troubles), you'll get all your last configuration (if then you make 3 wipes you lost all your configuration)
What to do before flashing rom
All u need to know is in this guide, thats all u need to do before flashing a rom, u dont need to partition sd card, do it if rom requires it
IN google type in"how to partition sd card to ext 4 with clockworkmod recovery" and click on the "androidarea51" link

3wipes mean data, cache, dalvic cache or something else ?

Yeah! wipe dalvik cache is in advanced options
Doing a ext4 partition in your sdcard don't get a better performance if your sdcard's class isn't 6 or 10, I think doing a partition isn't a good thing if you use your phone as a normal usage.

Ext4 works fine in GB with a custom kernel and the correct script
If you want to use a ext4 partition you'll need to flash a INT2EXT script, with a custom kernel that support it with his init.d folder
You can flash cf root, battery extender, spacekernel, nims11 whatever you want for STOCK roms and you'll get a init.d folder, then flash init2ext script and done!

There is no need to do 3 wipes, its completely pointless, by wipe, they just mean factory reset via cwm, you should also wipe ext4 partition, and dalvik cache
If you are upgrading to a higher android version, then you do not need to wipe if you would like you keep all your apps. If you are going to a lower version, wipe the phone AFTER you have installed the rom, but if you dont wanna keep your apps after upgrading, wipe straight after installing the rom
i hope i made sense

3 wipes mean doing Wipe data/ factory reset, Wipe cache partition and Advanced> Wipe dalvik cache from CWM. Make sure to backup your data before you do it. I highly recommend you do this along with Mounts & Storage> Format /system & Format /sd-ext (if you have an ext partition on your SD Card) from CWM before you install another rom inorder to have a clean installation as possible. Hope I Helped

It is not at all pointless. Usually when you install a rom through CWM, all files inside this rom zip will be copied to your phone replacing the apps and other files there. But one thing that still remains there is the residual files from the previous rom. It is neither deleted or replaced after the flashing. Now certain system apps read from such residual files as long as its there (if its not there it will generate it again, this being the main reason why your first boot is always the longest). Since the residual files that it is accessing belongs to another rom, it can cause all kinds of error leading to lags and crashes and you might even end up getting a bootloop. Wiping before installing a rom is recommended to remove such residual files and prevent bootloops. The only exception is when flashing updates of the same rom assuming that the rom didn't undergo any change in the system level (just addition of new apps, files, etc). In such cases you don't have to wipe but if the update has made the rom undergo changes at system level like featuring a new kernel, etc, then you might have to wipe. So its always better to follows the installation instruction from the developer of the rom. Always make sure to backup your data before you do wipes, so that you can restore it when you install a new rom. Long story short, if you installing a rom different from your current rom or an upgrade of your current rom that involves changes at the system level, then perform wipe before the installation. Hope I Helped
Correct me if I m wrong...
If u flash clockworkmod(cwm) recovery over official stock(gb) firmware, then avoid formatting ur stock rom via cwm, it'll result in bootloop.
& it's not necessary to format data/cache/dalvik AFTER flashing a new rom. Some roms contain /data folder which means that u shouldn't format data after flashing.
For newbies: U can check what folders ur rom has by using "root explorer" app:sly:

Questions on how to do a complete, 100% wipe

There have been several threads about this in the past, but I couldn't find one which is actually up-to-date.
I have been flashing my N7000 for years now. I've been using several custom recovery menu's and ROMS and re-partitioned my internal storage as suggested here. I currently have the following installed on my phone:
NightOwl 20151030
PhilZ Touch 6.59.0
ClockworkMod v6.0.5.1 (as shown in PhilZ)
What I would like to do is perform a full, 100% wipe of my phone before re-flashing the same ROM I currently have installed, perhaps even update my recovery or whatnot in case my phone would benefit from it (suggestions are welcome).
The original instructions from the NightOwl thread mention the following when you want to manually update:
1. Copy Rom to your sdcard.
2. Boot into recovery
3. Flash the Rom (in current versions you dont need to reflash the gapps)
4. Wipe dalvik-cache and format the /cache partition (This will not delete your apps or data)
5. Reboot
Click to expand...
Click to collapse
As mentioned these steps will not remove your apps or data. I understand that a "factory reset" does. However, I still wonder if this (including a factory reset) will actually wipe my phone 100% clean before flashing a new ROM.
That would be the following options in recovery
Factory reset to wipe data and cache
Format system
And if you want to wipe internal memory then format sdcard0.
Be careful of where you have the zip file of rom to flash again.
In CWM, go to "Mounts and Storage" section and there you'll find options to wipe totally everything.

If you are using twrp from this thread, it's mentioned on the 3rd post

FAQ / Further reading
Q: TWRP can't mount data partition, what to do?
A: Make sure you formatted data partition.
Q: Why do i need to format data partition?
A: Because old rom encrypted your data partition and new rom can't decrypt and use that content / root needs access to data partition to place misc files / phone not booting after flashing root until data partition gets formatted.

or maybe try to disable data encryption which is mentioned on the 1st post

You need to format /data with the "yes" confirmation.
The stock ROM will survive, because it's on /system and /preload.
After that you need to flash a fully patched kernel with removed forced encryption (like a2n kernel) before you reboot to the system. Otherwise the stock kernel will encrypt the /data partition once again.

i know i tried this but mine stock rom installed after flashing with odin (turkey) and after apply twrp format data stock rom are very different. the second i said seems like global rom. it contains weird settings and apps I will do what you say and take a screenshot,1 2 hours later you will understand me better.
