Hello,
I am about to install CM7. I currently Have Nookie Froyo 0.6.8 with CWM 3.0.0.5. I believe I need to update to CWM 3.0.1.0 first. Do I need to wipe / format the boot partition first or will the update to CWM / CM7 do that? What data lives in boot curerntly and what would be a situation / reason for wiping the boot partitition? When is it ever done?
Thanks in advance!

you should not wipe boot when installing cm7

OK. thank you, but what would be a situation / reason for wiping the boot partitition? When is it ever done? I'm trying to learn about all aspects of rooting / cwm.
Thank you

Not needed,running cwm will handle everything. Also the boot should stay so that SD keeps priority for recovery reasons.
There is a ROM Manager option to wipe data/cache, this should be done if changing rom types (ex nookie to CM7) but isn't usually needed between minor versions of the same rom unless issues arise.
It wipes the boot sequence, doesn't matter what rom you're going too, you need the boot data.
I've wiped it twice. Both times required I restored to stock before moving to a custom rom. Just wipe data and cache, and you'll be fine.
when going from nookie Froyo to CM7, you are changing the file system from EXT-3 to EXT-4. Remember to format /system /data /chache, and wipe Dalvik-cache within CWM 3.0.1.0 before installing the CM7 rom. By formating the three partitions in CWM 3.0.1.0 you upgrade the file system.
There is almost never a reason to format /boot. You will only cause problems that are annoying to fix.
Remember to do a backup in CWM before you format and flash CM7. You never know.
Hi Everyone,
I wanted to experience ICS, but after much reading on the EMMC Bug, I wanted to hold off until the situation was resolved to some extend, in terms of custom-kernals. Whereby, the EMMC erase commands are "disabled'.
So, I think it's time for me to experience ICS on my GT-N7000.
Presently, I have the following:
Builder Number: CheckROM Revo NoteHD V5
Android Version: 2.3.6
Baseband: N7000XXLA4
Kernal Version: 2.6.35.14-ver.4.2
[email protected] #3
I would like to do a "clean-factory-install" (meaning, erase everything, start from scratch, factory settings - no Titanium Backup, SMS Backup, etc.) to "Rocket ROM V10"
So, can anyone confirm if the following steps is what I need to do (I kind of mapped it, using extra precaution):
1. Boot into CWM (currenty has: RedPill Touch Recovery by AF974, CWM v5.5.0.4)
2. From CWM Main Menu, access Wipe Menu, then:
3. Wipe Data / Factory Reset
4. Wipe Cache
5. Wipe Dalvik Cache
6. Wipe Voltage Control Settings
7. Wipe Battery Stats
Afterwards, Go Back To CWM Main Menu:
8. Go to Install Menu
9. Select "Choose ZIP From SD Card"
10.. Select The: AbyssNote 4.2 Kernel (posted within the RocketROM thread)
Afterwards, Go Back to Main CWM Menu:
Repeat Steps 2 thru 7 *again* - - - just to make sure after installing AbyssNote 4.2 Kernel
11. From the Main CWM Menu, go to Reboot Menu
12. Select Reboot Recovery
13. Now I should be under the AbyssNote 4.2 CWM Recovery
14. Do All The Wipe(s) Again: Data/Factory Reset, Cache, Dalvik Cache, Voltage Control Settings (if applicable), Battery Stats, etc.
15. Install The ROM - by going to Install Menu & Select "Choose ZIP From SD Card" - point to RocketROM V10 zip file.
16. Reboot To System
17. Let The ROM settle down
18. Reboot Phone back into CWM (AbyssNote 4.2 CWM Recovery)
19. Install NoteCore / SpeedMOD Kernal (by choosing to Install From ZIP)
20. Do All The Wipe(s) Again: Data/Factory Reset, Cache, Dalvik Cache, Voltage Control Settings (if applicable), Battery Stats, etc.
21. Reboot!!!
22. DONE!
23. Enjoy ICS ...
Since you are already on GB kernel so it is safe to flash ICS rom, you can skip step 10-14, After flashin ROM you won't be able to re-boot in AbyssNote 4.2 CWM Recovery as it will be replaced by new recovery from the kernel included in new rom. Better to reboot normally and then flash another kernel using cwm recovery.

Hey jeetu1981,
I'll try what you have mentioned, and report back.
Thanks! (I'll click on the Thanks! Button Too...)
jeetu is right
at point 17 you will already be on NOtecore kernel so no need for step 19.
check your root status first after booting into new rom.

Hi Again,
Sorry just been really busy, I finally going to be having time to do this. Quick Question: Copy the RocketROM zip to internal sd card or external sd card, I am siding with external card, since the internal one is going to be deleted when I go through format/system, etc., right?
You can copy it to internal sd card
The data on the internal sdcard will not be wiped
If u want to wipe the data on the sdcard, in cwm>mount and storage>format sdcard

i am in the same boat. I have CheckROM V6 and looking for ICS update.
Can i ask why you need to do a full wipe? Why not just install the ROM on top and keep all the same settings?
Or reload it back with Titanium?

GB and ICS uses different settings and framework so restoring and using same settings OR flashing without full wipe is a no go I believe. same goes for ICS roms with different base like CM, TW, AOKP or MIUI.
You can flash rom without full wipe if the base is same (TW to TW etc) but then you will have lot of performance issues and FCs.
You can restore apps and data using TB but settings is still not possible.
hello every one

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.

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:
