[Q] how to update a rom?

i looked through the forum and didn't find this exact question so i'm sorry if it's been posted before.
basically what i'm wondering is if i have a ROM installed, let's just say one of the new ICS ones, and a new release of that ROM comes out, is there a way to upgrade to the newer version without having to install all my apps and stuff again through titanium backup? i hope that makes sense. in other words, is installing a new version of a ROM that you are already using going to be the same process as flashing a new ROM entirely? that could get annoying with newer versions of ICS seemingly coming out twice a week.
thanks in advance!

It's recommended to wipe and reflash, but I just flash over top and if there's problems I resort to wiping. Clear cache and dalvik and just flash over top, your apps will still be there. But if you do it this way, you should not report any problems

Probably could have used search to find this. But typically, unless the dev say to full wipe, when an update comes out for the rom you are using you can flash the update over the older version without a full wipe. You are still required to clear cache/dalvik to do this. If anything that was working before does not work anymore after you have flashed the update over the older version, then you should go back and do a full wipe and flash the new version. I personally always full wipe when flashing a newer version.

It all depends on the ROM and what is updated. Seriously you have to go by what the DEV says in his thread. Some you can update without wiping and some you have to wipe. Others will automatically wipe for you. Best advice is to read the DEV's thread. They should all give you this info. And if you looked over the first few posts of his thread you really wouldn't be asking this question here.

Some mods have the cache/dalvik wipe built in, so just make sure you read through the thread for whatever mod you're trying. Wiping it twice won't hurt, but just wastes a little time.

I know that we have different method for rom installation but do you have any idea about RunnyDrOiD
Thanks

really? man. I'll make this very simple for you.
1. put rom on root of sdcard
2. boot into recovery
3. wipe data, cache, dalvik cache
4. install from sdcard the zip file
5. reboot.
almost all ROMs except for the PD98IMG.zip stock ROMs are flashed with the above method. Not all ROMs require a full wipe (data, cache, dalvik cahce) when upgrading within the same ROM but it is recommended to do so to avoid any issues. If you're switching between different ROMs, it is required to do a full wipe. Search my good man.

Nexus S 4G Root issues?

I've been playing around with a Nexus S 4G that I have lying around and never used, and I've ran into a few problems, but you've all been helpful. I rooted all my old EVO 4G's without any problem, but the other day I rooted my NS4G using a one click/simple root and downloaded ClockWorkMod etc. But now for some reason It seems like I've almost lost my root? Is that possible? I still have the little unlocked symbol when booting up.
I've searched this forum and Google and haven't found anything, which could possibly be because I don't know what to look for. I've never had this happen :/
Currently running the stock 2.3.7

Nobody? I just need a little help.

Did you flash a superuser.zip after you installed clockworkmod?

Yes, it did. Thank you!
Now I just need to re figure out how to backup my stock rom on rom manager. I need to do that if I'm going to flash a custom rom onto my NS4G correct? I've never actually gone that far with my phones lol.

Okay lol hold on so just go make sure you
1. Unlocked the bootloader right?
2. Flashed a custom recovery (clockworkmod)?
3. Flashed superuser for root access?
4. Now you have a stock rooted ROM?
If you have/did all that then yeah you could backup your stock rooted ROM, you don't need to back it up but its helpful just incase you mess something you could always restore it to start all over
And you could backup any ROM you install incase you didn't know, just remember when you install different ROMS make sure to do a proper full wipe which includes data/factory reset/wiping DALVIK cache, and formatting system and boot in the "mount" option in CWM. And now I think your good lol

Unlocked Bootloader? If I boot in fastboot it says Unlocked. Is this what you mean?
I have ClockWorkMod, but I haven't done anything with it.
I have superuser from the root
and I was working with a stock ROM the whole time....
I think I'm ok lol
So I'll back up my ROM, and flash a Nightly CM9? And back that up as well? Just perform a factory data reset before doing so, right?

Yeah if it says unlocked your good to go. The super user.zip you first flashed won't be needed once you flash different ROMS, it was only needed for stock because you didn't install a ROM you just unlocked the boot loader and super user just gave you root access that didn't come with stock.
Yeah backup your stock ROM JUST in case you encounter a boot loop so you can just restore and start over, you don't need to back up CM9 that's completely your choice if you want . Its convenient though if you like CM9 but still like to flash other ROMS that way you can just go back if you miss CM9 without doing the whole setup process.
And a full wipe is
Data/factory reset
Then wipe dalvik under "advanced"
Then wipe system and boot under the "mount" option in CWM

I'm not sure if I'm supposed to post links to videos or not. But I'm in love with some of the features this guy has on his NS4G
https://www.youtube.com/watch?v=IKdyAm3CgHc
He said it was a nightly etc.
The hidden status bar and bottom menu hidden is amazing. I also like the inverted G-Mail and Facebook. Is this all separate from the Nightly ROM?

[Q] I did something bad in ICS

I thought I could flash a theme to the stock ICS leak. But apparently that doesn't work because it's not de-odexed. Is there a way to de-odex the stock ROM on my phone? If not, is there a way to undo my theme flash (I forgot to make a backup ). Or, can I go back to stock ICS by just flashing the Odin one click ICS leak?

If you're not worried about losing anything try factory reset. Sometimes themes will stick, if it does just flash through Odin and your good to go.

Yeah, I tried the factory reset. It didn't do anything. I'm not worried about losing data though. I have everything backed up with Titanium. So, I can flash directly from Odin without clearing cache, etc through CWM?

Themes do not work on odexed . Period. Flash one of the custom . Deodexed ics roms if u wsnt a theme
If u flash the collective ics rom . You will not loose data or anything. Just download and flash. It will sort out your issue. And give u a good rom check it out here. http://forum.xda-developers.com/showthread.php?goto=newpost&t=1548469
Its the 4.0.3 ics rom at the bottom of the op

I'm a little confused. Do I just flash it in CWM without wiping anything, or do I follow these instructions?
1. Make a nandroid backup, it is always a good idea
2. Have your apps backed-up with titanium
3. Downloadrom, and place onsd card
4. Shutdown, and boot to cwm recovery
5. Wipe data, wipe cache
6. Select mounts/storage, and choose format system
7. Flash rom
8. Fix permissions
9. Reboot.
10. Enjoy

[Q] Question about updating roms.

This a general question about apdating custom roms...
In cwm there is an option 'Update from sd' or something like that... What does it do?
Plus, If i have a rom installed into my phone, like for example a Version 1 of the rom. Do I have to wipe everything before installing version 1.1 or can I just flash it unto the other rom without wiping everything?Do I have to wipe only when a version 2 of the rom comes out? Ask the developer? EX. Real ics 5 to 5.1, to 5.2....
I have the same question for FXP cyanogen mod. If I have FXP149, Do I have to wipe everything before installing FXP150?
THANK YOU!

Depends what the instructions in the ROM/Kernel/Theme/ thread says.

Use the "install from sd card" and choose the updated file for your custom rom then install after install just wipe cache & dalvik cache then reboot

A small question Flashing rom/mods.

When we flash a mod or zip file [for eg. DSP manager] through CWM. And if it is not working on the rom how do we revert back to the stock rooted rom?
1. Just go into CWM recovery and restore Nand backup [no wiping anything]
2. Wiping dalvik & cache and reboot phone [no need to restore via backup]
3. Wiping AND Restoring via CWM
4. Or any other way to remove the mod [flashed zip] without restoring nand backup.
Please specify which things we have to wipe .
I am asking this question coz its really a pain to restore backup all the time if the mod [zip file] doesnt work with the rom. Thanks!

Can you try this one?
See the folders in that zip file you flashed. See the paths of different files inside it and delete it.
Like if you flashed dsp manager. It has dspmaneger.apk in that file under system/app folder and other updater scripts.
So you can just delete dspmaneger.apk from system/app from root of your device's storage. Same with other files too.

Thanks for ur reply..But i was later going to flash ACID mod...So the dev told me to get back to stock and then flash it.
If i could just remove the DSP manager like u said and flash acid rom..Then why is the dev of acid mod asking me to get back to stock?
If I have already installed Acid Audio Engine, should I just flash your mod over it, or should I go back to stock and then flash it?
Go back to stock and flash. Never mix soundmods

anyone?

Hey sorry for not replying.
There is no system where you uninstall the mods unlike you do with apps.
The method i stated above should work after clearing cache etc. But if the auther of the mod instruct you to use that on stock rom then please follow his instuctions
______________________________________

Mods are different and I don't know about what you installed, but it's certainly safest to restore to stock and then try the different one - that way you don't have unexpected "pieces" hanging around that may conflict with the new one.
When I restore a backup, I treat it like a completely new ROM, I wipe everything (after all, it's going to restore everything) and then hit "restore".
