If you install cwm and then do a repartition,does that nuke whatever rom you are using thus requiring a reinstall?
Hi,
If you follow the normal instructions (make sure it's CWM .8, and not CW Recovery or whatever it's called) to re-partition system and swap wth CWM, I believe that the "system" means the "/system" partition, where all the apps, etc. are stored, so "yes", using CWM to re-partition "system" and "swap" (to 2048/0) effectively wipes out most of the ROM.
Since the re-partition only changes (re-partitions) those two partitions, it doesn't touch the other partitions (there are a bunch), such as the recovery partition (where the stock recovery or CWM live), the boot partition (where the kernel lives), etc., but when you then flash a new ROM after doing the CWM re-partition, that replaces all of those, plus puts the new stuff from the new ROM/flash into /system.
NOTE that apparently SOME (not all) of the stock TNT firmwares (e.g., TNT 3452) include the recovery partition, whereas some others (the earlier TNT firmwares) didn't, so, if you flash 3452 using CWM, it replaces CWM (again, which is in the recovery partition) with the stock recovery. So, for those TNT firmwares that include the stock recovery, you'll need to re-install CWM .8 AFTER flashng those stock TNT firmwares (again, not all of them do that).

Is it simply wipe /data /system or do we have to do something like on the captivate and return to stock first?
How about if we switch kernels etc - does the process change?
Thanks

When switching ROMs, the easiest way is to do it with ClockworkMod Recovery. You download the .zip of the ROM you want to your SD card, boot to recovery, wipe data, cache (this step is only necessary when going from one ROM to another, not if you're just updating a ROM), and dalvik cache, choose install zip from SD card, point to the .zip you downloaded and install. If you have a kernel you want to install, then you boot after you flash the ROM, reboot to recovery, and flash the kernel .zip from cwm recovery
Ok, with all of the talk about making sure folks do a full wipe before installing ICS, I would like to get some clarification on all of the different wiping methods and which is the best way...
I know of these ways:
1. Via custom recovery - you can wipe data, system, cache, etc.. individually.
2. Via holding Power+VolumeDown until bootloader text appears,, then wait until menu appears and select the Wipe Data option (instead of the cold boot option).
3. Via AARD SuperWipe full script
And then of course, there is the "Reset to factory defaults" in the OS itself...
Which is the best to use? I would assume the AARD SuperWipe full would be the most thorough as it recreates the partitions and everything (instead of just formatting them).
FOr users that have the ability, would an NVFlash of the OS be "more thorough" than CWM method?
Opinions/Experiences?
Thanks!
Don't use super wipe script. A lot of people reported having problems of some ROMs not flashing correctly after using it. There is no reason to use the "full" version anyway. It formats the /media partition(your internal storage partition) which you don't want to nor need to format.
Wipe Data in your #2 does pretty much the same thing as "Reset to factory defaults". They both wipe /data and /cache but do not touch /system.
The most thorough way of wiping that I use is via CWM.
I do all of this within CWM if I want to ensure a clean install of a new ROM and it has never failed.
- wipe data/factory reset
- wipe cache partition
- advanced / Wipe Dalvik Cache
- Mounts and Storage / format /system
I am not sure how NVFlashing a ROM does a clean install? As far as I know, it just flashes whatever it's told to flash. It wouldn't even touch /data if you were just flashing a ROM with it.

I've tried ALL of the above methods - all with the exact same results, to be honest...
Even if I revert back to honeycomb (even after a full wipe), I STILL exhibit the reboot issues (it's not just me - look around). This was NOT happening before with the exact same version of Revolver. This tells me that there is still yet something else that was changed during the ICS updates. We know the bootloader was updated - i'm now testing ICS with the old bootloader.
Other than the bootloader, what else could have changed?? Unless they upgraded the firmware on a particular device during the ICS update (wifi chip, bluetooth chip, etc). Other than that, I just can't come up with an explanation as to why Honeycomb won't even run properly anymore!

If you use the --create flag, nvflash will format ALL the partitions and then flash them. If you use the --download flag, it will just overwrite the partitions you send it.
That being said, I agree at your wiping method is more than enough. Most times, I don't bother wiping, especially data.

There's are a few threads with how to return to stock, but it mainly describes how to install stock rom.
Whenever I flash a new rom, the files in the "download" directory remains untouched and it looks like other files elsewhere doesn't get touched.
Is there a way to return the unit to absolute original stock condition (not just ROM). That is everything in the unit?
I've been having some issues and installed various roms and such and I wonder if that's why it's acting up.
Thanks!
Power off the device then ,Power and volume down do factory wipe or reset i forget. That should clear the internal memory and put all settings back to original
I do the factory wipe when installing a new rom, but the files in the "download" directory and other previously created directories for other apps like "zinio" or "perfectviewer" seem to remain untouched. So I wonder if there are other stuff that is not returned to 'stock'?
Well you should be able to delete anything on /sdcard the most it would do is break apps you installed and your pictures and what not. If im not mistaken /sdcard is your internal memory and /removable/microsd is the external. So if you delete the contents of /sdcard then flash stock rom and do wipe you should be back to stock. I did a factory reset and it did clear everything in /sdcard.
When you do a factory reset in CWM or TWRP, they format all of /data except /data/media/, which is where /sdcard is mounted.
You will need to flash the stock ROM, which should install the stock recovery also (if not, find the stock recovery image, and flash it). Then, like the previous poster said, boot into the bootloader and do a factory reset from there. The stock recovery will erase everything in /data, including /data/media, and it will erase your internal storage.
Do you also need to do this before flashing a new kernel via CWM? Or is this only needed when you flash a new rom? And another question: what is the fastest and most stable kernel for Gingerbread Galaxy S Plus Stock Rom? And if I do everything like the guide, is there no risk? Thanks in advance:
Do this every time before flashing a stock- or custom-rom!
Attention!
You will delete everything on your phone! Your phone will not even be able to boot! Only Clockworkmod and the Download-Mode will be left! (Your SIM-Card will be untouched)
Please make sure that you saved only your backups on another device before formatting your phone (like on your computer)
This is the best method for using the full experience of every custom rom! I recommend this method because in the past a lot of users had issues with custom roms. They had installed a lot of different custom roms before and they didn´t format their phone correctly before flashing the new rom. This caused a lot of problems
Enter in the Clockworkmod
Choose "advanced"
Choose "Wipe Dalvik Cache"
Go back to the main-menu by pressing the back button
Choose “Mounts and storage”
Select all after all
Format /system
Format /cache
Format /data
(Format /emmc)
(Format /sdcard)
Formating "emmc" and "sdcard" is not a duty! You will need it if you installed a mod on your internal or in your external card
Hello
First of all, I'd like to excuse myself because of my lack of knowledge in all that android stuff and also in english. I got my phone rooted just by following tutorials on internet.
I have a Huawei Ascend Mate 7 MT7-L09. Probalby half a year ago, I have unlocked bootloader and installed CWM-based Recovery v6.0.5.1 and got it rooted.
Not long ago, Huawei released a new version of the EMUI, wich I guess is the Android 6.0 marshmallow thing (logically, I was using the previous version). After downloading, I tried to install it but it would reboot to the CWM everytime I was trying. And then, after booting, the phone would tell me the update failed. It's normal, I know. I needed to install it manualy and etc
BUT instead, by pure ''I don't give a crap what may happend'', I did some big crap.
First of all, in the phone's settings, I did a factory reset. I made a backup of all my files and data before (not in the CWM, but in the phone's tools). After the reset, the phone booted in an old-fashioned android version.There wasn't any keys to go home/back on the bottom of the screen. Because of this, the phone was almost unusable because I had to reboot the phone to leave an app and select another.
I raged and booted to the CWM by pressing the + button and the lock phone button.
I went to Mounts and Storage Menu and did all of this
format /boot
format /system
format /cache
format /data
format /storage/sdcard1
format /data and/data/media (/sdcard)
I did the wipe data/factory reset
I also went to Backup and Restore
I made the
delete from /sdcard
delete from /storage/sdcard1
free unused backup data
choose default backup format
I went in Advenced Menu aswell
I chose
wipe dalvik cache
I think that's it. No wonder why it doesn't work well now LOL...
Later on, I thought I may try to fix it. After reading some stuff, I downloaded a package from the official Huawei website, I think it was with the 5.5.3 EMUI or some sort of. After mounting USB storage to my pc, I put the zip file, wich was not really a zip file because it had a .tar format, it would show me by going to the install zip: Impossible to read format lol. Then I found a package of a rom wich was zip. After putting on the phones storage this zip it would start to install and show installing update and then show me: Installation aborted. Then i gave up and decided to ask some help from pros.
So..... What should I do?
I know my explications are weird, but this is the only way I can describe my problem.
Thank you for reading this long story, and even a bigger one if you help me.
hi,
i don't know cwm recovery.
I suggest you install TWRP recovery , then flash the rom image found here.
(i have installed B571 by this way)

tar is another compression format like rar and zip.
If you have the software installed to use terminal commands (ADB) to connect to your phone when it is in so called 'recovery'or 'fastboot' mode you should flash the TWRP recovery image for Mate 7 posted somewhere on the forum for better compatibility. It is basically similar as CWM (clockworkmod) but newer.
In another post here there is a summary of firmwares and in that list is also the 'Twrp Backup' of a fresh installation. That should be downloaded, unpacked and placed in the folder where other/previous backups are stored. To find out where that it is you can create a backup yourself in recovery but only select the 'boot' so the backup is done immediately (and useless) and you can browse your phone to see where to put the downloaded recovery backup.
Next is restoring that backup within recovery.
Personally I would also do a factory reset after that but you should be ready to go after that.
