[Q] Question|root and new ROM and apps

If I root my desire and flash a custom ROM will all the apps I have installed now
would be gone?
And if I bought an app, will I have to buy it again after rooting and a new ROM?
thanks
oh and im sorry if this is in the wrong section

For the first question, I think all your apps will be deleted just if you want. In doc kitchen, are two versions of rom, with wipe and no wipe, but the recomanded version is that which will wipe all your data. You can backup all your apps before that.

You can just back up all the apps via Titanium backup from the market. It will also backup your user data.
So you should go:
1) root & install custom recovery (usually part of rooting process)
2) install Ti Backup and run a batch backup of all user apps and data
3) make sure all your contacts are google contacts! Then they will just be re-imported when you register your google account on your new rom
4) pick your rom and download its zip file - copy this to the root of your sd card.
5) boot into recovery and factory reset i.e. wipe everything
6) still in recovery, select "install from zip" and pick the zip file above
7) reboot and wait (can be slow the first time), then run a batch restore from Ti backup and you are done!

Thank you very much its very helpful.
Do paid apps stay as well?

Yep they will all be backed up.
I forgot a step too - you should always do a nandroid backup (this is done in recovery) before wiping and flashing rom in case something screws up.
This way you can restore what you previously had through recovery.

When you paid an app on the Market, the info is attached to your Google account. So when you configure a new rom with your Google account, you see in the Market those apps are paid and you can download them again for free.

How do I change to a different ROM?

A total noob question but that's because I'm a noob. Anyway I'm currently using CynogenMod7, but I want to try a diffrent ROM. What do I have to do?

All the info you need to do that is here

Okay but would I have to format my SD card or partition it?
How would I keep my old apps and app data?
Thanks

You dont need to format SD Card (some ROM's require EXT partition, if you dont have it then you might need to repartition it), to keep apps and app data use Titanium Backup.

Backup apps using Titanium Backup
Backup contacts
Boot into recovery
Perform Nandroid backup
Wipe/factory reset
Install new ROM from zip

some basic things before flashing ROMs
Depends on what ROM you're trying to flash. Some ROMs don't require partitioning your SD card. However, ROMs that feature A2SD+, Data2SD, Data2Whatever or Data2Ext will require that you make 2 or 3 partitions. Those 4 scripts are for people who have tons of apps and cannot be served by the stock phone memory.
Safest way to enjoy flashing ROMs is to:
a) save all the stuff in your SD Card onto your computer or another storage device
b) sync all your contacts into a Google account. If you don't have one, make one. You'll find it very convenient to sync back all contacts everytime you flash a new ROM
c) use MyBackup Root or Titanium Backup; they can both save apps for later reinstatement, include settings and data, like your Angry Birds score. Personally, Titanium Backup is much better than MyBackup Root. Go buy the pro version, it works even better.
d) remember to make a Nandroid backup in recovery. Be aware, though, that when you make a Nandroid backup in ClockworkMod and in the future decide to flash Amon_Ra or another recovery, those cannot restore the nandroid backup that CWM did. Amon_Ra nandroid backup can only be restored by Amon_Ra recovery, likewise with other recoveries. So the first step to do after flashing a new recovery is to make another nandroid backup, in case of trouble.
e) remember the golden rule of safe flashing: always wear a condom. Ooops. I meant, wipe data, cache and Dalvik-cache. Many problems with hanging or bootloops can be traced to not doing the 3 wipes.

Alright thanks everyone!

Go into recovery, full wipe/factory reset + dalvik cache wipe and flash new ROM.
When you flash CM7 dont forget to also flash google apps (look in first post)

Upgrading to GB on the DInc

Hey guys, so I'm a noob and need a little bit of help. I just downloaded this:
http://forum.xda-developers.com/showthread.php?t=1219407
Now, what do I do with it? Also, will I lose all of my data by flashing this onto my phone? (ie: my texts and my homescreens, etc?)
Thanks!

are you rooted? if not...

once you have clockwork recovery and all that, boot into recovery, 'flash rom from sd card' (after putting the zip file on ur sd) and ur good.
If you dont want to lose everything, after root, download titanium backup and run that. you will be able to apply most of your stuff back on once you flash a new rom.

howbout some thnx -.-'

I'll give you some thanks for that succinct explanation of steps to take.
I'm ready to root with unrevoked - guessing I should use the "flash and recover" version instead of their "forever" one?
I installed Titanium backup, which I'll use after rooting to backup pretty much everything that it can grab.
Then, I'll use the SD card-based install that you mentioned.
I've read that I should do a full wipe before installing the OTA ROMs being offered - is another tool needed for that, please?
- ooofest

You've got it. The newest version of Unrevoked has made the "forever" one obsolete.
You will be able to perform all the wipes required from within Clockwork Recovery.
Also, make a clockwork backup (nandroid) as soon as you have root, so if you run into any problems flashing roms you have something to restore.

Lost sd card storage after updating to Jelly Bean

Sorry to bother u guys, I am no expert at all this root and recovery stuff, but I took on the risk of updating my Samsung Galaxy Nexus GSM version 4.04 yakju to Jelly Beans without making proper research and got myself into a bit of trouble.
So I read some random tutorials that I found on the internet and combined with previous flawed experience, I attempted to update my phone
I did something like what this tutorial said:
Step 1: Unlock bootloader of and root your Galaxy Nexus. Additionally, flash ClockworkMod Recovery.
Step 2: Go to Settings > About on your Galaxy Nexus and note the Android version and build number.
Now, with that information in hand and knowing whether your GSM Galaxy Nexus is a yakju or takju variant*, go the following thread over on [XDA-Developers ] forum and download the appropriate .zip file to update to Android 4.1.1 Jelly Bean (Build: JRO03C).
Step 3: Transfer the .zip file to the root of the /sdcard directory on your Galaxy Nexus.
Step 4: Now reboot into ClockworkMod (CWM) Recovery.
Step 5: Take a nandroid backup.
Step 6: Choose install zip from sdcard > choose zip from sdcard > [file you downloaded in Step 2]. This will flash the Jelly Bean update on your Galaxy Nexus.
Step 7: Once flashing process is complete, select reboot system now from CWM’s main menu.
I'm still not quite sure where I got it so wrong, but after updating to JB, the phone will not recognise my SD card anymore
So if I went into Settings>> Storage, it will say that I only have 80mb of internal storage. (Should be 13.3GB)
When I connected it to my computer and updated my driver, it also only showed 80mb of internal storage.
Basically I panicked and restored my nandroid backup
Can anyone tell me what I did wrong?
There were a few tutorials online that also said updating from 4.0.4 to 4.1 will not wipe out any data. At least now I can prove that bit wrong hahaha

I'm not sure if you were prompted to wipe the phone or if it did it automatically, but the first time you unlock and root your phone it will need to be wiped.
I'm not sure what went wrong but the first time I attempted to root my gnex it failed and I wasn't sure what went wrong. Tried again and it worked fine.
Also, once you root/unlock, I would install titanium backup to keep your apps and data when you flash. Without TB (or other backup), I think the only way to keep data through an update is through the official OTA. But as always, someone on here has likely run into the same problem...

It happened to me so I just used titanium backup to backup my apps, flashed to stock 4.0.4, downloaded the ota file on my PC and flashed it through fast boot temp cmw recovery. Then you can root it and restore your app and settings.

thanks for ur response！
you see, my phone was already rooted and unlocked ages ago, so i basically ignored the first step and jumped straight into recovery mode to install OTA from zip file……
I know everyone tells me to backup using titanium, but i dont really know how to use it, it seems slow and just stops now and then…… i will give it another try……sigh
Sent from my Galaxy Nexus using xda app-developers app

For best results you should do a full system wipe before flashing a new ROM. Titanium is only needed if you want to backup your apps. Having a nandroid is what's really important. So between running a nandroid and updating to the JB .zip, do a full system wipe and try it if you really want JB.

[Q] Downgrading via CWM

Hi, maybe a stupid question.. If I update my phone to 4.2 and then I want to come back, is restoring a CWM backup after a full wipe enough? Or do I need to flash a Google image from scratch?
Thank you for your time.

Are you on the latest version of CWM? The reason I ask is because the earlier versions are incompatible with Android 4.2.
Anyways, you should be able to restore a nandroid backup of 4.1.2 (or earlier version) after wiping your system/data/cache.

I recommend that you switch from CWM to the latest TWRP because when I upgraded to 4.2 with CWM I faced the sdcard/0/ issue so CWM could no longer find the nandroid backup to restore it. I have no idea if this has been fixed in CWM but it is working fine in the latest TWRP recovery which I am using now.
Take note that CWM backup is not compatible with TWRP backup so you have to make a TWRP backup to restore it later.
If you would like to have TWRP then you have to do the following assuming you are already rooted:
1- Download GooManager from the Play Store
2- Open it then install the TWRP recovery
3- Switch off the phone then go into TWRP recovery
4- Make a backup using TWRP
5- Do whatever you want now but remember that if you are wiping everything then you will have to install TWRP recovery again (either via fastboot or by rooting then downloading GooManager to install it) after starting the new ROM in order to restore your nandroid backup because wiping everything will wipe the recovery as well.
I hope that is clear
