[Q] Restore to Stock

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.

[Q] Nandroid backup

Hi all
Is Nandroid backing up all the apps I've got at that moment? Or it just saves system files?
Like a complete and exact "photo" or are there things that I should do on my own if I mean to recover exactly as it was...
I assume that no wipe is necessary...
Thanks!

What's the truth about Nandroid backup?!
i guess there's no need to open a new topic, because i got kinda the same question
before you guys start to redirect me to the "search" function, i want to assure you that i have been using it, but i have found myself in a very strange situation, one question, two different answers... and because i'm new to the whole root stuff, i want to learn everything correctly before starting to make modifications to my phone
The question is: Nandroid backup, does it also back up the kernel or not?
I mean, if i root and install a custom rom that also comes with a custom kernel, will i be able to use my previous Nandroid backup to restore my phone to the old rom & kernel?
Searching the forums, i have found 2 totally different answers!
Answer 1: Nandroid does not backup the kernel: http://forum.xda-developers.com/showthread.php?t=806340
Answer 2: Nandroid does backup the kernel: http://forum.xda-developers.com/showthread.php?t=844352
So, please make me and all of us root noobs understand once and for all, does it backup the kernel or not?, will we be able to restore from a custom rom+kernel in case we need to?

and does it backup apps?

OK...As I understand it....
What does Nandroid Backup?
The ROM Itself..Obviously.
All your system settings, emails, SMSes, etc
All the Apps you have installed, so no need for TB
The Kernel you have installed (though there is controversy about this, and to be honest, I have never restored a nandroid backup when I had a different kernel already installed...however it really doesn't matter since kernels are easy to flash)
What does Nandroid NOT backup - This is VERY IMPORTANT
The modem (not a big deal)
The File System setting (A BIG DEAL)
This I think is where the confusion arises concerning the kernel being included in the nandroid backup. For many people the kernel is all about the lagfix. If you have installed a lagfix on your phone via the kernel, say changing the file system to Ext4, and then flash a Nandroid backup that includes a stock kernel or other kernel that does NOT support Ext4, you are in for a world of hurt...and in this case hurt means endless bootloops.
The way you avoid this is, if you need to flash a Nandroid with a kernel that does not support your lagfix...go into recovery, disable whatever lagfix, tell it when it asks that you wish to REBOOT INTO RECOVERY after the change....then flash the nandroid you wish.
This is why it is very important to keep regular nandroid backups, and to wait and see if a ROM/Kernel are stable for you before applying lagfixes or other tweaks.

So, let me see if i got this right, Nandroid does backup up my current kernel along with my rom, but if i apply any changes (lagfix) to my kernel afterwards or change it with a custom one with lagfix, nandroid won't be able to restore it anymore...
so the whole problem here is that nandroid is not able to backup / restore The File System setting, this being the rfs / ext4 transition
If this is the case, it seems that the Nandroid type backup is not as powerful as i thought, you can't really change from one rom to another in just a few clicks, but then again i guess that all the customs roms already come with some type of lagfix and you can make a nandroid restore between them, the problem would be when you want to revert back to a stock kernel, then you'll have to disable the lagfixes or simply flash a stock kernel and then restore the stock nandroid backup
so, i got this right guys?

Yes as I understand it.
You see Nandroid can't convert your file system or change anything, all it can do is flash a disc image onto your phone. If that image can work with your file system, you are golden. If not, it is like flashing a Mac OS image onto a Windows machine....nothing will work right.
However the good news is that most custom kernels support Ext4...so really the only problem comes when you try to flash back to a stock image...or vice versa.

got it then, thanks for your answers
and, if i still got your attention, maybe one more question
i just downloaded a stock firmware from samfirmwares.com, and all i got is a .tar file, can i use it somehow to flash just the kernel from it or i have to flash the whole firmware?
if i flash the whole firmware, will it also change my PHONE and CSC?, because the .tar file must be put just in the PDA section in odin

Yes, it will flash the PDA, csc, modem and kernel...the whole shooting match. The single file firmwares are designed like that to avoid mismatches and issues. Once you flash it, flash a kernel that supports cwm (I suggest speedmod or something by CHAINFIRE) via odin, then flash a new csc and modem if you wish from recovery.
Remember that installing a new csc will do a factory reset so do it before reinstalling apps.

great stuff man
finally i got enough info and i can start my root & flash procedure, guess i'll also learn a few other tricks along the way, this community is definetly the place to be if you want to learn how to "really use" your device
the whole info about the issues with the Nandroid type backup should be integrated in one of those massive info topics, so the root noobs like me know what they're dealing with

Hey guys i actually used the search button (yay) and this is definitely the most informative one regarding the topic.
However i still have one more question: does it backup files and folders as well? Ie. my Nexus S storage is mainly used up by my videos and music (about 7-10GB) which are in their own folders and not tied to any apps in particular. Hence if it does include those i wouldn't have enough storage space to create a nandroid backup am i right?
Edit: thanks to the search button i didn't realise that i posted on a Galaxy S forum please forgive me, the question should still be relevant to the topic though

As I understand it, it does save folders and files, so yes if you have large data folders on your internal SD it will make GIGANTIC nandroid backups. You may want to store such files one your external SD.
I know that there is a version of CWM that does not backup /data/media in Nandroid on the Galaxy Tab 10.1...perhaps there is something similar that I don't know about for Galaxy phones. Does anyone know?

Flashing over a rom?

So im wondering, what is the standard practise, or based on your own experiences. What is the best way to flash over an existing rom using CWM? What do you do to prepare the fone for new rom, wipe user data, dalvik cache, before or after flashing. Just trying to get a good idea of how to do it.
Sent from my SAMSUNG-SGH-I897 using XDA App

going from rom to rom:
put rom.zip on /sdcard/
reboot to recovery
install zip from sdcard
point to rom.zip
flash
reboot
any rom that has been properly done will wipe user data and dalvik cache for you. no need to do it manually

i always flash back to eclair and master clear with odin one click to make sure all files from previous roms are gone then CWM flash new ROM

lets look at the master clear function shall we?
when you flash to stock...your entire / is stock (RFS, eclair 2.1, /data /system, etc)
essentially, you have just reformatted your root, think of it like formatting your C drive and your sdcard is like a secondary internal drive that contains storage
master clear at this point will only delete items off your /sdcard
roms dont care about your /sdcard, master clear is worthless when you are stock
there was a time where it was necessary to flash to stock to reset the filesystem and then flash the rom. it has not been needed in months, but it continues to get preached as gospel.
even flashing to stock isnt necessary unless you are trying to come from CM7 or MIUI....or if something goes horribly wrong

Thx for info guys, I have flashed a few times and it seemed like now and then my fone must became bogged down and needed to be fully wiped, sound didnt work or lagfix folders bunch of text docs, just seemed cluttered. So if wanted to really clear out junk what would be a good way without having to flash back to stock?
Sent from my SAMSUNG-SGH-I897 using XDA App

Just flash. If you have a problem then back to stock Ans a MC. I have flashed hundreds of time back to stock once.

I would definitely agree. I have also seen people say to disable lagfix before flashing. I have not done that either and never had any problem.

Would just like to amend the advice already given with the following:
Pre-flashing:
1. Titanium Backup of apps and data
2. Nandroid backup in case something goes boom.
Post-flashing (assuming success):
TB restore of user apps/data only. NEVER RESTORE SYSTEM FILES.
They may not apply to some people, but I feel those are necessary steps for anyone that actually uses their phone daily.

why not restore system files? Does this apply if coming from flashing back to stock first, or just flashing from one rom to another?
Glad to hear the advice about not flashing back to stock, that's been one of the major reasons I haven't flashed quite as many rom's as I want, too time consuming.........not to say that i'm not flashing a couple rom's a week, but there's just so many options to try

Making "search" a standard practice would be very helpful.
Restoring system is known to mess up ROMs in all cases. Though may not be mandatory, but make it a standard practice to flash stock. Takes hardly 10 mins, and helps save big headaches later.

Incompatibilities across rom versions, mostly. As the guy above me said, restoring system files tends to mess up a rom because you are overwriting part of it with files from a different rom.
There is one caveat, however. If you're flashing back to a rom you originally performed the backup on, you can safely restore system files. For example, if you were running Cog 4.3 and did a full TB backup, then decided to flash Serendipity 6.3, you would want to restore only your user apps and user data. However, if you decided to flash back to Cog 4.3 at some point, you could do a full TB restore without worrying about incompatibilities.

I agree with everyone else. Flashing over another rom seldom causes issues. I make s nandroid backup of my favorite rom with everything setup the way i like it. then flash away trying different roms. When i am done, i just restore my backup and all is good!

I have done a search, couldn't find the specific answer I needed, hence my asking. Could be I wasn't phrasing the search correctly......but here I am.....
To clarify, what do you dpo to get your system settings back after flashing a new rom? I flashed to serendipty 6.4 last night, as per the advice, I didn't restore system files, just apps and data, but that didn't work so well for me. I lost my data connection, could only use my wifi, and had no contacts, or any sms msgs. I don't know what else was missing, but I then went and restored system files, everything came back as needed, and there seems to be no issue......
How do I get my info setting back, or do I just need to manually re-set everything after flashing? Apart from wireless info, msgs and contacts, what else do you lose by not restoring?
Appreciate your help

havent flashed a new rom in a while and forgot if anything extra was needed when flashing a rom over a rom
thx!

[Q] Help with stock Milestone 2.2.1 from Germany

Hi everyone,
I know this will make me sound like a complete noob but it doesnt matter. Any help or any pointing in the right direction would be greatly appreciated.
I have a stock motorola milestone 2.2.1. I hate it and have read how stable some of the roms are and I would love to experiment with them. However, never having a windows phone or an HTC before I have no idea how to do this with minimizing the risk.
So I have rooted my phone with universalandroot and have installed rom manager and titanium backup. Unfortunately, I read that rom manager wont work with the Milestone.
All of the threads on boot recovery and other methods seem to differentiate from one another. Is there a safeR method. I know no method is safe. What programs do I need to install on my computer and or my phone for this to work?
I know this a lot and I truly appreciate any help and support from this forum.
Thanks

First of all, ROM Manager does not work with the milestone. So please remove it and dont ever install Clockworkmod recovery on the milestone.
Second, What ROM do you want to install?
You need Androidiani Openrecovery for all your flashing needs of customs ROMS. You will need rsdlite to flash sbf files and offcourse the Moto usb drivers. Check the sticky threads in the development section. There are many tutorials.

This is easily one of the best ways to get everything done in the way of flashing a custom ROM.
http://forum.xda-developers.com/showthread.php?t=983516
Depending on which ROM you want to install, it will determine what you need to download.
After rooting the phone, you will want to flash a vulnerable recovery sbf via RSD Lite, as shown in that thread the VR you should use will depend on your bootloader version. If you are running 90.78, then you can flash this VR: http://android.doshaska.net/rootable
After that happens, you can create a backup of all of your apps using TitaniumBackup.
Once you do that you want to place OpenRecovery(AOR) on your SD Card. Follow the steps from the first link I posted to get that on. You will want to place the custom ROM that you want into OpenRecovery/updates. If you are planning on using CM7, you will also need to download google apps from the CM7 thread here.
Once that is on, you will want to boot into recovery(power+x, see the Moto M logo, then release and push camera button+volume up), apply update.zip.
From there you want to select the Nandroid menu with the d-pad. Create a nandroid backup of what you want.
Now is the crucial step. You need to wipe the caches and ALL data. Choose wipe dalvik cache, wipe cache partition and wipe data/factory reset.
Now is time to apply your custom ROM!
It is recommended to create a nandroid backup everytime you flash a custom ROM, in case of anything going wrong.
Navigate to apply update in AOR, select the ROM that you want, select yes. Once it is done installing, wipe the caches and data AGAIN.
If you are installing the google apps, you will want to wipe the caches, flash the google apps, then wipe the caches again.
You will probably have to apply the baseband for your carrier, so you will need to navigate to change baseband, and apply the baseband for your carrier.
If you followed those steps, you should have a brand spanking new custom ROM on your phone.
Hope this helps.

Before you start reading, please make sure, you are 100% sure of ur answers, and that you have TIME to answer them ALL with clarification
Really thanks for ur time and help!
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!

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 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...

What are the other advntages with the CF Root kernel? I can't remmeber why I puted it, but I think they were another reason behind it...
Where I can get teh stock kernel? Or which one you advise?

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...

Really thanks for ur time and help!
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.

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