To Upgrade Rom..Question

Please forgive the noobish question..this is my 1st android product and I am still learning...
I am currently using Task650's rom version 5 along with the current pershoot kernal....If I want to move to Version 6
1. do i only wipe the delvrik cache,then flash version 6?
2. do I need to reflash the kernal after flashing version 6
3. what is the easiest way to backup all my apps if i have to wipe everything and then put them back?
i am using a rooted 10.6 wifi only...just really trying to get the hang of if there is an order to flashing roms and kernals like if i install a new rom or even update if i have to reflash kernal and reset setcpu?..thanks in advance.

Please Anyone... I really wanna do this...

1. Most scripts wipe dalvik cache when install or upgrading a ROM. Check with rom author if your not sure. With V. 6 from V. 5 its not necessary.
2. Yes, V. 6 will flash stock kernel. Unless noted in original post from ROM creator, custom ROMs "generally" have stock kernel. Other forums this is not true. You will need to setup SetCPU again after flashing.
3. Titanium Backup, it's a very powerful tool for backing up data apps. Rule of thumb, DO NOT backup and restore system apps, you can put your device in a bootloop or other bad things like applications that force close all the time.

Just a FYI: no need to boot the rom first though. Flash ROM, directly flash Kernel and then boot up. Good luck!

I've seen it recommended to reboot between the ROM install and kernel install. Though I can't say that there is harm that I am aware of.

for #1, task650 said: "You only need to wipe dalvich and cache to upgrade from V5"
for #2, havent tried to flash the kernel yet but will give a shoot asap
Any advice how to do it is more welcomed
for #3, titanium backup ftw

Ways to go back to Stock from PA?

Hi,
I am about to flash the PA rom on my N4 but before doing that I need to know how easier I can come back to my stock setup.
I have made a complete nandroid backup but I am not sure if that will work. My baseband and bootloader are already latest versions so that's that.
Actually I'm not sure if flashing the stock rom back is the only way so need to confirm that.
Thanks!

You can either go back to stock by flashing the stock nexus 4 images, or by restoring your nandroid backup that you created while you are on stock ROM.

Or you can simply download the deodexed stock 4.2.2 ROM and flash it via recovery. Just wipe cache and dalvik cache.

But it isn't really stock because he won't get OTA's if the rom is deodexed, right?

If you flash a stock ROM from XDA whether its deodexed or odexed it won't install ota because its signed differently

Thank you so much for your helpful responses, I was able to "test" and successfully restore my previous setup using a nandroid backup so no need to flash stock images/firmwares
So, we have two options when we want to go back to previous rom:
1. Either flash a factory image as mentioned (which erases all the system data etc etc)
2. Make a nandroid backup before installing a custom rom and restore the backup if youre not happy with it
Cheers and Thanks again! :good:

Steps to follow before flashing a new rom

Hey guys, im currently on paranoid android and want to try the xenon hd rom, i read it's recommended to do a full wipe before installing a rom if your running a different rom. Is there any steps I have to do other than a reset, flashing the rom and the gapps, plus the wiping of the cache and the delvik cache?
Regards.

its always recommended to make a backup(nandroid) of your current rom before flashing anything, just in case. backup, wipe data, flash the rom, flash the gapps or kernel if needed, reboot and profit. you dont have to wipe the dalvik/cache because when you flash a rom it automatically wipes it anyways.

One little thing to add to what simms wrote, whether it's recommended or not in the corresponding thread, when you move from one rom to another a full wipe should be a golden rule.

Omega rom upgrading questions

I have couple questions about upgrading omega rom.
1. Should I do factory reset, wipe cache and wipe dalvik when upgrading from 9 to 10?
2. Why should we flash modem seperate than rom ?
3. Which kernel will be included in omega 10?

Its up to you, you can try a "dirty" flash and not wipe and see how it goes, If there are problems then do a wipe.... If you don't want to set up your phone again then make sure you have a nandroid backup and stay on the older version.
Some people need a different modem because their reception is no good with the new modem or it causes battery drain. This would be the reason you would flash a new modem. Easier to leave a lone and see what happens, you can flash a modem.bin file later if needed through ODIN or, my preference, Mobile ODIN....
Read the changelog in the thread to see what kernel is included...

1. Should I do factory reset, wipe cache and wipe dalvik when upgrading from 9 to 10?
You should full wipe when flashing a new rom, but wiping cache and dalvik cache will wokr fine too
2. Why should we flash modem seperate than rom ?
Because each modem works different from other in your region
3. Which kernel will be included in omega 10?
Modified kernel based on stock one

U don't need to do a factory reset specially upgrading from 9 to 10 cause both 9/10 are 4.2.2 based Roms and moreover they are from the same developer.... As for wipe/dalvic cache, the installer does it itself...
Simply go into recovery and flash the file... U should be good to go...
Good luck!

Sorry to hijack this thread but do we need to change gsm and lte modems if getting poor reception after installing omega (I have installed omega 19 and getting poor recption ever since)
Thanks

Those aren't zips...
To the OP, OTA updates don't wipe your internal storage. Just install 4.4 stock and wait for those.

stock file
As far as I've been able to research it... Installing the stock 4.4.x from a 4.3 rom will require a complete erasure of the data on your internal storage.
My choice is a Titanium backup and transferring the files to a safe place. Followed by a nandroid backup - again stored off-phone it is perhaps belt and suspenders level, but when it hits the fan.. that is when you will be really happy you made the effort.
I did the factory rom 4.41 using fastboot.. and waited for the OTA to 4.4.2 --(file from https://developers.google.com/android/nexus/images‎)

Coming from a custom rom, it would probably be a good idea to do a system data wipe. Otherwise, on stock 4.3, you could just dirty flash and wipe the dalvik cache.
