Hey, urm new to the rooting business so please bare with my newbness. (i have tried searching)
Can someone quickly run me through updating a rom..
i.e Cyans just released an update, i understand i need to download and flash. But do i need to wipe before flashing? do i need to then re-flash my theme after flashing the new rom? So, does flashing an updated rom loose you all your data?
Thanks, love you guys.
If you're going from one Google based ROM (Cyanogen, JF) then you shouldn't need to wipe. If it's a HTC based ROM, then you would need to wipe.
So go ahead and flash, you shouldn't have any problems. If you find that you get stuck in a bootloop, just boot in to recovery then wipe and reflash.
If you dont have apps2sd and you wipe, you will loose them. If they're on your ext partition they will remain there.

Is it 100% neccessary to wipe before updating a rom if its the same rom just a different version? Like I have cyans 3.6.8.1 and want to go to cyans 4.0.1
I'm just looking for some clarification on this matter. I know when you switch roms you want to but I haven't really seen anything concrete on upgrading roms. Any help would be appreciated
No, no, no.... you need to wipe when you use a bathroom, not when you flash software
People will hate me for this but... here it goes
We wipe to avoid problems with the new rom. We DO NOT know if we will have problems, good chance that we will NOT. I never wipe untill something goes wrong, and I was just fine for last 14-15 flashes.
Here's another way to think about it.... do OTA updates wipe your phone? Didn't think so.
Flash away. If you have problems then, and only then, nand back to your previous configuration, wipe, reflash. Don't wipe after flash... Cyan's roms don't like that AFAIK.
Good luck.

I heard somewhere that it's best to wipe when going from HTC rom to Google rom and vice versa. I know that for cyan's roms that if you rarely have to wipe (I had to wipe when trying out 3.9.11.*), but for the most part you won't have to (went from 3.4.6 to each update until 4.0.1 without wipe)

At this point..the only HTC roms we have are Hero and that's a whole another story. Not only you have to wipe but also reformat your sd. Big mess... not worth it IMHO. Your mileage may vary.
Thanks for ppointing this out though...
Personally, I wipe, then repair ext filesystems before I flash a new ROM. The only time I don't is when I'm updating a ROM that I have, cm x.x.x to cm x.x.x, in hich case I'll just repair ext's then flash. But, when in doubt...
Original question(s) seem to be solved.
Closing thread
after rooting and flashing ROMS, im confused on somethings. When flashing a new ROM do you ALWAYS have to wipe? Also, when you make a Nandroid back up, wipe and flash a new ROM, can you restore from that backup so you dont have to download all your apps//set up your screens all over again? Please help.
If you are switching to a completely new rom, then yes, you have to do a complete wipe. If you are upgrading a rom, adding mods or something similar then you don't need to do a data wipe. If you are switching from a rom that uses apps2sd from one that uses it you should probably wipe your ext partition as well.
To answer your second question, a nandroid backup backs up EVERYTHING on your phone, so using a nandroid restore will knock out your new rom and put everything back the way it was, including apps and settings. If you nandroid back from your new rom (lets say your phone gets stuck in a boot-loop or something...) you should do a data wipe and wipe ext partition, then nandroid.

I want to use stock Android 2.1 ROM but want to use SetCPU to overclock. I tried flashing this kernel: http://forum.xda-developers.com/showthread.php?t=690238 but was stuck on the white/green HTC Screen. I then tried this kernel: http://forum.androidcentral.com/162759-post49.html and it got rid of super user permission so I couldnt use SetCPU. Is there another kernel I can use? If so can you PLEASE provide download link? One more thing, how do I compile this: http://forum.xda-developers.com/show...ghlight=kernel

It has your apps2sd info in it, hence wiping before changing roms because most use different versions of a2sd.

Ok... I'll give you what info I can, but I'm somewhat new to this myself... the first kernel you tried to flash has to be used in tandem with the rom listed at the top of the thread (darchdroid...) the second needs to be used with damage control's rom. I don't understand why you lost su permissions by flashing the second one, but again I'm new to this.
I hope you made a nandroid backup (always do this, otherwise some people around here will flame you...) I would restore, try installing the rom for the kernel you want to use and then re-flash it.
Something you might like is freshtoast (check: http://geekfor.me/new-release/fresh-toast-v21/) it has a stable rom (fresh 2.1.x) and all the overclocking goodies you're looking for. That way you won't break your phone / lose root in the process.
P.S. your link is broken for your last question, so I can't answer it

I don't want to use a rom. I was told I can overclock if I use a custom kernel. Which kernel should I download from the second link and heres the last link: http://forum.xda-developers.com/showthread.php?t=684838&highlight=kernel
Sorry for the delay... long day(s) at work!
For your kernel problems, please read this guide: http://forum.xda-developers.com/showthread.php?t=622916
It gives you step by step instructions on how to compile and install (probably the wrong term, but whatever...) the kernel you want.
In order to use setCPU you'll need a custom kernel, the CDMA Hero doesn't support it straight out of root.

Hope this helps, but as far as more in-depth kernel questions, you'll need to find someone else to ask, I'm all out of ideas
I was hoping to flash Paragon tonight, but it said to flash to stock first and I had a few questions.
Why do some ROMs have you flash to stock while others you can just flash through ROM Manager?
Is the Stock backup I made through ROM Manager sufficient as a subsitute for an Odin flash?
If not, are there any Mac alternatives out there?
I'm trying to get a good understanding of what I'm tooling around with so I don't brick my phone.
Thanks for the answers
I wish I could answer all your questions, I'm guessing it's because the recovery uses a zip file and it does not update everything that odin would. Anyways, if you need any help flashing to stock I know that the FAQ page of the cognition rom found here has directions.
cognition.theidiotshideout.net/mw/index.php?title=ODIN#One-Click_JF6
It is not needed but many think it is best. Depending on the rom you are on you have a cocktail of lag fixes and kernels. Flashing stock gives a clear slate.
You can disable lag fix, delete davlik cache, clear cache. You should be fine but you may run into issues. May.
What are you running?
It's some sort of ancient lore past down from priests of captivate forum antiquity.
As for 'cocktails of lag fixes and kernels,' there is no reason your cwm install can't format those partitions, particularly in light of the fact that it has built-in support for ext4. I don't know why people think the stock flash functions are particularly better at dealing with it.
Do yourself a favor, make sure you have a working download mode combo, purge your mind of the flash to stock FUD and obliviously commence to flashing one froyo ROM right over another. You'll be glad you did.
So if I'm hearing you correctly, it's more of a this will make sure you have no issues and are starting from a clean slate. It's not 100% neccessary to flash to stock before flashing a new rom?
Meanwhile, I was furiously trying to get Odin to work on an old laptop I scrounged up to no avail. Sometimes my need to tinker creates so many problems.
Thanks, guys!

It is like a default disclaimer to flash stock. If you flash the rom and have an issue, one if the first things they will ask is did you flash stock. As mentioned almost all lag fixes use some form of ext 4 filing and most clockwork recoveries can now handle ext 4.
So in summation you do not need to, if you flash and get stuck in a boot loop you need to. I would make sure you can get odin up and running, and recognizing your phone in either case just so you know you can use it if needed
Absolutely no need at all to flash to stock
Would you install Vista in order to install Win7?
As long as you format everything in CWM before you flash a new ROM, then everything is a clean slate. It'll wipe your stock install, so why install stock first?
This and the 're-calibrating' your battery are the two biggest FUDs about Android.
Let's say i have gignerDX5 installed and want to update to v6. Do I have to backup all my apps and data (sms, phonebook) again?
Simple answer is no, you can just upgrade and it will keep all user data.
You should however make a backup in Xrecovery just in case something goes wrong, if all goes well then either move the backup to PC for later or just delete.
I updated from Froyobread to GingerDX and still kept my data and apps.
I make somethimes fullfactory in Xrecovery,if I switched to new room.It´s not bat to make back up in Xrec.of old room.It´s your game,wher you have back up.I use Titanum backup pro and my acount for phonebook and calendar.I do´nt need anything else for change the room.
Hi...
I have a question, and I didn't wanna create new thread, cuz its related to title
When I flash a new rom, its recommended to do a Full Wipe... Do I have to do that before or after flashing a Rom?
You don't need to do a full wipe when you update GingerDX. Just install it and reboot. I didn't have any bugs by not making a full wipe.

If you're coming from 2.1 to DX do a wipe, I tried first time yesterday installing rom and got stuck on cyanogen mod boot screen. Did a wipe, reinstaled and worked.
So do wipe if coming from other rom
Hey guys,
Sorry if this seems really noobish, but I seem be to kinda lost in all of this ROM'ing goodness.
I have read up on installing custom roms and plan on doing so but I have a couple of questions first before I take that last step (already unlocked and rooted on my One) - note: I have read through the guides but I still seem a little confused as to what exactly changes.
I notice that all tuts mention that you will lose all data on your phone. Does this include installed apps or are we just talking system files needed for the new rom? I have my phone setup already and have my apps backing up with Helium (Carbon) but this is something I seem to be a little confused with
Secondly, using something like CWM (Premium), can I update my ROM quickly and easily without losing any data?
I know that unlocking my bootloader will not get me OTA's so I am looking forward to using many of the awesome ROMs here on the site!
1) When you flash a rom, you need to do a full wipe in aroma.
Full wipe will erase all but not the sd, so your app in home, your background, your account will be erased.
2) You can upgrade your rom with CWM if is the same rom and the base isn't different.
If the base is different you have to do a full wipe.
One more
How likely is base to change for a ROM package? And if I have to flash that new ROM package instead of doing the update through CWM, am I back at square one again with my apps and data or is it just updating what it needs to?
Thanks again for the help!
Then:
Now, all the rom is based on 1.29.401.13.
When it will change (it depens from htc) and you will flash the latest update of rom, you have to do a full wipe, and you will lose all file, settings and other.
Instead, if you have to flash an update like: you're on 2.5 to 2.6, you can flash the rom with only dalvik cache and cache wipe.
But it depens, you always have to read in thread rom
I guess its not so big of a deal considering I can backup most of my apps using Helium and the rest of the apps can just be redownloaded if I keep a list. Configurations should be backed up anyways.
Thanks for the help!
If you're rooted and you will restore your app after a full wipe, i advise you titanium backup.
With this you can do a flashable zip with all your apps and data
Thanks!
I will take a look at Titanium backup and see what it can do! It would only make sense that someone would invent a way to backup all your apps and data (no matter what) to be able to restore them after a ROM update that wipes the phone completely!
Titanium backup can do this
However, only data app, not system app.
If you backupping system app too, you can have issue with new update of rom
