I've installed clockworkmod on my phone, however I am cautious about installing a rom that requires a different kernel as I'm unsure how to return to stock kernel for a different rom.
How do you return to the original kernel?
You can download a flashable zip for the stock kernel (sorry I dont have a link atm) and you can install a rom which has the stock kernel included. You can also backup your rom in recovery (make sure you have enough space on your sd card, I recommend about 2Gb because a backup can easily be more or less 1.5 Gb) and restore again if you dont want the custom rom anymore. The backup will include the kernel. Always make sure you use the wipe data button in recovery before you install a rom or restore a backup! Also check if the kernel for CDMA or GSM, Idk which one you have, because installing the wrong one may brick your device

process to flashing a new ROM... follow this religiously and 99% of the time you will have no issues.
wipe data twice
wipe cache twice
(no need to wipe dalvik cache when you wipe data, because dalvik cache is in the /data/ directory, so when you wipe data, you are wiping dalvik cache)
format system through recovery or do what i have always been doing and flash a .zip that formats system, data, cache, all that for you in one move.
the synergy superwipe.zip is a great tool to use, so is virus' infectedwipe tool. either of those.
also, i haven't been using clockwork mod for a while, but if it is able to backup your boot.img separately, back it up. your kernel is packaged in your boot.img so if you flash a completely stock ROM, and back up your boot.img, you have effectively backed up and saved a copy of the stock kernel.
hope that helps.

hi, i wanna ask...if i wanna flash to another devoid.Franco ROM (previously using void.echo) do i still need to dl the Terminal Emulator & Custom Recovery Tool Image and its Flash Image then run the Terminal Emulator & key in the codes then only start flashing another ROM?
i've did tat at the first time i flashed to a void.echo ROM now i wanted to flash to devoid.franco, do i still need to repeat all that step again? or i just enter the "power button, volume down button and home button" mode then wipe then flash will be good?..need advice thanks..
Just wipe and flash..
thanks for quick reply!
another question...how do i know that i already have the ext partition?...after i wipe everything included wipe ext..do i still need to create again?
Wiping doesn't remove partition..
On Mike mod
can we install franco kernel on mike mod 6.5.2
If your from void#echo previously, do these:
1. Backup all your user apps+contacts via Titanium Backup and all SMS via SMS backup
(they're all available free in the market)
2. Turn off phone. Reboot to recovery (hold power button+home+vol down)
3. Wipe user data, .android secure, cache, dalvik-cache, battery stats, and wipe ext.
4. Since your on void#echo already, you don't need to partition your sdcard.
5. Download devoid.franco, use usb-toggle on the recovery menu and copy it from pc to your phone while on the recovery and flash it.
6. Reboot (first boot might take a while)
7. Configure settings, Install titanium backup and sms restore app, Then restore all apps+settings+SMS. Enjoy~
8. Well if you know already what your doing and want some further improvements (completely optional, just do a nandroid backup incase) :
8.1 Reboot to recovery
8.2 Flash the latest kernel version from franco's thread
8.3 Reboot
8.4 Flash the ZRAM module
8.5 Reboot and Enjoy your phone
Thanks Kira.Lawliet!
hmm...i actually partition my sdcard again...yea..i flash before saw your reply ._.
will it harm? i partition my sdcard again....n flash to devoid.franco
You have to partition only if you want apps2sd. Else let it be. You can easily remove the ext partition by partitioning with 0mb ext partition in recovery.

definitely you can. just flash your device with mik_os mod first. then flash the franco kernel (v15 now) and lastly flash the ZRAM initializer.
just make sure you wipe the cache and dalvik cache first before you're flashing.

Ok guys just remember that rom flashing requires you to follow rom partition conditions while kernel flashing may not need to recreate partitions. In my case, I'm using Nessy Hypnos2 and been running with much fluidity after flashing FrancoKernel 14.2. But I did wipe all just to make sure there wont be any conflicts. HYPNOS2 + FRANCOKERNEL 14.2 is like coffee and cream, a perfect match like newlyweds.
Hello!
Today I just wanted to revert back to the newest MIUI weekly (with the stock kernel). It's just suits best for my daily usage. Before that, I've used bunch of Custom ROM's, used Siyah kernel and done some OC.
Now, my question is: Together with the usual things like:
- Wipe data/factory reset
- Wipe cache
- Wipe dalvik cache
Is it good idea to also format partitions under CWM recovery (/system, /data or some others) to get as fresh, clean install as possible (just don't want to have any traces of ROM's, kernels or settings I had before). Didn't find any clear answers about that so that's why I'm posting it here.
Thanks!
I've done it a couple of times, had no problems. Just be sure to have the MIUI (Or whatever ROM you want to use) zip on the SD card.
Hi!
Yes, I do have the MIUI ROM zip on my device. So, to get as fresh install as possible, should I format all those partitions ? (/system, /data, /boot, /cache)?

For best result, install stock ROM & then hard reset . After that you install whatever you want .

Thanks sendhiloo7! I will do it then
Couple questions I have.
What is the correct procedure for flashing ROMS? Heard you have to wipe cache and dalvik cache, where do you go to wipe dalvik cache?
Do you always have to flash a ROM twice?
When flashing zips for ROM fixes, do you have to re-install base ROM then the ROM fix? EX - Running AOKP Milestone 5.2, there is a problem with the Internal storage mounting. Downloaded a fix off jokersaxs website. In CWM I cleared the cache, flashed the ROM twice and the Internal memory still can not be found.
Thank you for the Help!

1) Depends on what you are flashing. Before flashing the file you will want to read up on it first. Usually there are guidelines in the OP. If you are not sure than best to ask first and make sure you have a backup created. It is a good idea to wipe cache/dalvik several times before flashing. This can be done via your recovery (in CWM dalvik is located under "Advanced" menu) or there are zip files you can flash which will do the wiping for you. I usually do both.
2) No. But with certain roms it is recommended to help prevent issues. Usually if it is needed it will be stated somewhere in the thread.
3) Should not have to but here again it depends on the type of file/fix and if it is necessary should be listed in the OP. Usually just the fix can be flashed otherwise it would be easier for the dev to post an updated rom version to flash.
Hey guys,
Just installed my first rom and my head is spinning at the unanswered questions i have.
my first question is regarding clockworkmod
if i go into "apply update from .zip..." theres an option that says "apply /sdcard/update.zip". That option was there even before i loaded a custom rom. If i clicked on that when I have a custom rom running, what exactly does it do. My understanding is that "update.zip" is from the original rom. Is that correct?
Second question
What is the difference between doing a wipe data/factory reset from CWM when compared to doing it through the settings menu?
I never make a back up because I have no issues starting over but i just realized that some roms require you to install it with a "stock device." If a rom requires a stock start, does that mean you have to odin and wipe it to the stock rom before installing that specific rom?
If a rom doesn't require you to have the stock rom, does that mean you can just flash over custom rom after custom rom?
In those situations, do you move the rom.zip to the root folder THEN go into CWM and wipe dalvik THEN choose "install zip" or is it another order?
Under mounts and storage, what does "format/system" do? is that the same as "wipe data/factory reset"?
maybe i should just go back to iphone. this is just a cluster**** of info.
Update.zip is old stuff, as you suspected its to do with official updates. Cwm works across many devices that's why it's still there.
Your phone is divided into several partitions. They are prefixed with a / because the Linux convention treats partitions exactly the same as directories. Unless you have been living under a rock you probably know android is a fork of Linux.
/boot contains the Linux kernel
/recovery contains the recovery mode software, in your v case cwm.
/system holds the system apps and files.
/cache is similar to the swap file on a Windows pc or the /tmp directory on Linux. Dalvik cache is stored here as well although I'm not 100% site how that works. It's something to do with the java runtime.
/data is all your user settings and apps.
Factory reset wipes /data and /cache thus removing all installed apps and your account settings etc. A factory reset achieves the same thing regardless if you launch it in cwm or from the settings menu.
When changing roms you don't need to go back to stock first, it's just the way some devs have written their instructions. You should however always wipe /cache when changing roms. A full wipe is not usually required unless you are changing to a completely new base e.g. upgrading from an xxalf Rom to xxlfb you shouldn't need full wipe or going from one xxlfb Rom to another shouldn't need wipe. Changing from a Samsung based Rom to something like Cyanogenmod you should always full wipe.
Always wipe before flashing as some roms modify /data.

thank you for taking the time out to write that.
What is the difference between advanced restore and advanced back up against regular restore and back up (in CWM).
Also, which exactly do i have to wipe. Which cache? There are three different options i think.
Lastly, if i made a nandroid backup of the rooted stock rom in its stock form with no mods, do i still have to wipe the cache when i install a new rom?

Advanced backup and restore lets you choose which partitions to backup or restore, vs the standard option which backs up everything.
As I mentioned earlier you only need to wipe the cache. Dalvik cache is a sub directory of /cache so wiping /cache will wipe that also.
You should always wipe /cache when installing a new Rom. It doesn't affect anything from the user perspective except that first boot will be long while android rebuilds the cache. It probably isn't strictly necessary when moving to roms with the same base but can't hurt since it has no negative impact. Even factory updates wipe the cache automatically for you. Some custom roms do as well but better safe than sorry since most don't tell you either way in the description.

Hi, I'm not exactly new to XDA, however my Note is my first real Android phone. My question is this: If I want to make a backup of the entire phone, so that I can install a new ROM, then restore the phone to exactly the way it was before I installed said ROM, what do I need to select to back up in TWRP? I'm wanting to play with the Lolipop build for i717. I already have a good EFS backup stored separately just in case, so I need to select System, Data, and Boot, and this will save the kernel and the ROM contents, correct? ...and when I restore this backup it will be just like I left it, right?
Also, what do I need to select to Wipe to perform a 'Full Wipe' as is recommended before install?
Thanks for your time.

Use gimmeitorilltell's version of twrp as some specifics have not made it to official version. I've had great results using 2.8.0.0 though I believe some newer versions are working now as well. I backup android secure as well. Not sure if this is necessary, it was the default setting. Wipe is generally accepted as factory reset usually followed by going to advanced wipe and checking cache, and dalvik cache and wiping these again. Then install your new rom zip, gapps zip if required, wipe cache and dalvik cache and reboot. First boot will take a long time. Possibly as long as 5 minutes or more. Once booted let rom settle for at least 10 minutes before adjusting any settings. Good luck.
Edit: Your backed up rom system will restore everything back to the way it was if you desire to go back (installed apps and settings as well).
