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.
This thread seems like it may contain your answer: http://forum.xda-developers.com/showthread.php?t=699792
I also highly recommend heading to following link, it has tons of guides and will answer most of your questions: http://forum.xda-developers.com/showpost.php?p=6738713&postcount=1
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
Hey folks, so here's a basic summary of what I've done up to now...
Rooted... have Rom Manager, etc...
Flashed JH7 OTA with Clockwork. Worked nicely. Set some things up, happy at this stage so I made a backup.
Decided to try Cognition, was 2.1.4. Had some trouble with a few things.
Disabled lagfix, simple enough.
Flashed to a backup made when I was on regular JH7.
So to the question... when I go to About in Settings, my Kernel still says
[email protected] #Voodoo_lagfix_3.0_v1.9.
Shouldn't the Kernel have converted back when I restored/flashed my backup?
Clockwork won't reflash your kernel (unless it's a package with included kernel) however the voodoo kernel you currently have on your phone operates the same as a stock kernel until you remove the disable-lagfix folder. Cognition 2.1.4 does utilize that version of the kernel to enable init.d scripts for things like MobileAP to function
You just have all the answers don't ya?
Thanks again, really appreciate it.

Can this new recovery be used to flash CyanogenMod 6.1.1??? I just got the new recovery update on rom manager and was going to flash cyanogenmod 6.1.1 and just checking. I thought the new recovery was for flashing Gingerbread roms?? Any help would be appreciated.
Thanks,
Vinny
I don't see why not. You can try and if it don't work you can flash an older version in ROM Manager

I am not sure about that. But one thing for sure is it is not good for MM's CM7. I have loop-reboot problem with this. I cannot even restore to any custom roms except my froyo stock. :-( Now, I have to downgrade to 2.5.x.x to see if my custom roms work again.
See development section.
EDIT: I successfully restore other custom roms using lower version of Clockworkmod. But the loop-reboot problem of MM's CM7 remains the same.
I guess I won't find out until I try. Newly rooted and going to give CyanogenMod a try. Know I am going to be happy as hell with it.
Thanks
The new recovery should be fine with flashing any roms. As for any standing problems with it, im am uncertain. You may want to wait 2 weeks or so to see if their are any problems from people using it. Personally I like Amon ra so i cant say.

A full wipe is necessary to upgrade to gingerbread roms from any lower android versions. Did u full wipe? + Dalvik cache wipe?

I used it to flash and install tonight's build successfully...
I have a "side question".
To flash any GingerBread flavor, do we need 3.x.x.x ou 2.5.x.x is working?
I haven't give CM7 a try yet, but I'm not sure if I need/want to upgrade to 3.x.x.x, 2.5.1.4 work well for me.

I got it too. No more crazy rebooting. I solve it by reformatting my SD card and recreating ext3. I guess 3.0.0.5 recovery messed up my ext3 partition. Now, MM CM14 is working pretty well. FYI, I am using 2.5.1.4 recovery.
Yeah it was working good till I try to do a restore, lets just say I;m up all night trying to restore my phone. I think my EXT partition messed up too as DTa2sd is giving me all kinda of headache.
doesn't work with MIUI for me!
don't understand that, but luckily its not a big deal flashing older versions!

I hear you there! That was me last night! DON'T USE 3.0.0.5! The only fix I found to actually work was to completely format my SD card and then re-partition it, then use RA and a fresh install. What a pain in the arse!
Same thing here. Switched to 3.0.0.5, and the next thing, my ext was fried and I had to reformat the entire card. Could be coincidence, but...

Hi All,
Just joined the forums today after a few weeks browsing. I must say I am very impressed with the level of knowledge here and how helpful people are to others, especially noobs like me
Anyway, I got a nook color, but I am in Ireland, so I can't register it, that didn't worry me too much, because I wanted to root it, and after much reading on these forums I decided to use CM7.
My build at the moment is as follows, built with Clockwork,
CM7 RC4,
Dalingrins's OC kernel emmc 0413A,
Alsa 041411
First thanks to all the people who made the mods/ kernels etc Your work is really appreciated I am loving the nook color now with the mods.
I just have a few very basic questions, lol and I am still getting to grips with the right terminology
1. Does it matter which way I install mods/kernels etc? I understood that you had to install the CM7 mod first, but, for Dalingrin's OC kernel and Alsa, I installed the kernel first than Alsa, or does it matter?
2. If a new kernel comes out, or an update to Alsa, do I have to uninstall the old one? Or can I just boot into recovery mode wipe the caches and install the updates?
3. Same question for the CM7 mod, If I want to try some of the nightlies, can I just put the nightly on an SD card, wipe caches and install it the same way I did the RC4 version? will I have to reinstall the other kernels if I do this?
4. What happens my data and apps if I do update CM7?
5. I made a backup on the SD card using clockwork. Is this just a backup of the system files? or is it a backup of data and apps as well?
6. I am trying to learn more about this, in performance settings there is a thing called VM heapsize. Is there a recommended value for this?
7. And in the CPU settings there are a number of options available under "available governors" what are govenors? and which one is best? Is there an explaination available for each one?
That's all the questions I have for now. Very sorry if these have been answered a million times already!!

You should be able to upgrade with CWR. I have CM7 on a SD card and just add the new kernel and boot into recovery mode.

Since the nightly has its own kernel, you will need to reinstall the OC kernel.

They shouldn't be affected.

So i got a samsung galaxy ace, it's rooted and with b84 CF-Root kernel.
1) The thing is sometimes, I press Wi-Fi button or Bluetooth, and in the Wifi it says Error and on bluetooth just won't conect. I don't know what the problem is, and the only solution is to reboot the phone. Is this a problem? Can it be fixed? If It can, how? If not, please read point number 2.
2) If its not fixable, what ROM you advice me to reinstall? I have s5830XWKS2, some people say the DDxxx8(or something like that) is better don't know why I'm no programmer...
2.1) If I really have to have to reinstall it in order to fix it, how can I do it? Can you point out the thread for it?
3) I run a small business, and I use Tasker for all my stuff. together with other 60+ apps I need to keep, i'm using SD card with ext partition with Link2SD. And the thing i'm most afraid of, is loosing all the data. I came from a Nokia 5800XM, and I flashed it some times, backups are easy to do. Now here on Android becomes a bit complicated. Maybe never someone cleared me enough about it. So what can I do to sucessfully restore all data on the new ROM? I got Titanium backups, and CWM..Will that backup even my dictionary saved words?
4) Thanks, and please, again, make notice that I can't loose anything due to my business, but I can't work with phone needing to reboot at random times cause of wifi or bluetooh beeing bricked.
First of all. There is no such things as urgent situation here. You should remember that.
Second thing. You should post questions in Q&A sub-section. General is for sharing and discussions.
Third thing. There is a adb logcat thingie, which allows to understand a root of your problem more than 'Help me. Something doesn't work'
I remain this thread open but move to correct section.

Yes I experienced the same problem,could be software bugs problem so I think you can reinstall your software for the better.
I prefer cm mod7/8 for ace as it is much faster so you can try Google cyanogenmod for ace. They have all the tutorial you need.
As for your Apps, titanium backup will do fine. Its the best backup so far. Your dictionary words is the default system one? I recommend you smart keyboard pro as it has the function to backup all your words
So in short, backup your EVERYTHING with titanium backup, rmb your contacts too, and install cyannogen mod 7 or 8 whichever you prefer! Hope this helps!

There's no such thing as cyanogen mod 8...only unofficial cm 7.1 kang and official cm 7.2...
Nunopitbull, wifi & bluetooth problems that you experience are caused by the kernel, not the firmware or rom...so my suggestion is to use a kernel that is not based on cf root or use a stock kernel (the one that came with your phone)...just root your phone with the update zip method will do, and for cwm flash the zip for it...the newest version for sga is 5.0.2.6...there's no need to flash a custom kernel...
About cwm backups, it backups your whole system and data partition and also your boot.img (kernel related)...so yes, it is quite safe to say that your whole phone is backup-ed...but keep in mind that stock roms use .rfs format for the partitions...new custom roms use .ext4 format...so to flash a backup of a stock rom, first flash a fresh stock firmware with ODIN and the cooper.pit file...then re-root and re-flash cwm to restore your phone...
And fyi, link2sd uses a second partition right? The apps inside the second partition can be relinked if you reset the phone...as long as you don't format the second partition...but personally I suggest you to use DTa2sd or amarulzz script as it saves more internal space...check it out...
Hope that all the above helps...
So you're saying my problem of wi-fi/bluetooth is because of kernel? Can you help me by PM how to get it working again? I wanted a custom kernel don't remember already why, but I think was for the custom speeds of CPU, so I could have low ones..
Just want this bug to disapear of bluetooth and wifi!

So far I haven't seen a custom kernel for sga that works flawlessly...especially the ones with oc function...only stock kernels work with the least problems...since you want to underclock, just use the stock kernel and set it to the lowest value with an app like set cpu...it shall do you fine...

Chill please...don't shoot questions in here...if you want quick answers, please search about it (e.g. go to the cf-root thread and read about the features, I don't memorise them, but I believe you want the overclock and a2sd features)...If you want direct answers, you will have to wait...
I understand that you need your phone for your business, it's very important to you...I'm trying my best to help out here ok? To get a stock kernel, just flash a stock firmware via ODIN...but you will have to re-root and re-flash cwm...any stock kernel will do, as long as it is with the firmware you flashed...

Try flashing a new kernel, this is NOT a rom issue, just a kernel issue.
