Unlock/Root/Custom Rom warranty question

Unlock/Root/Custom Rom warranty question - Samsung Galaxy Nexus

I know it says unlocking my device will void the warranty, but is there any way I can re-lock it later on so I could send it in for repairs or something in the event I have to do that? Would they be able to tell if I had previously unlocked it?

Yes...you can simply restore the device and relock the bootloader. The toolkit in the stickies in Verizon galaxy nexus development makes all that very easy.

Awesome, just needed confirmation I could do that if I had any problems. Thanks!

You can flash the stock images and relock the bootloader, and they can't tell.

One more question. I have CWM installed and made a backup in it (plus an apps backup in Titanium)
If I, say, install CM9 and something weird happens (for instance, the radio magically stops working), will restoring from that CWM backup restore stuff like the radio and such (in addition to my stock 4.0.2 ROM, etc)??
EDIT: So I've backed up my apps with Titanium, but now the guide I am using says to wipe my device in CWM before installing a new ROM. If I do that, won't it also wipe the backup I just made?

CWM backs up your ROM, kernel, recovery and data. Not your radio or bootloader. But all the radios are available in the radio thread and all the boot loaders are available in the bootloader thread

No, a wipe in CWM will not wipe /sdcard.

HELP NEEDED with CWM "error while restoring /data!"

Hey guys,
I have kind of a serious issue right now. I used Touch Recovery 5.8.0.2 and made a full backup today of my whole ROM (2.5GB) before trying out some mods which eventually didn't work. So I decided to wipe and restore the backup I made. No matter what I do I cannot get it to restore my data partition properly. I keep getting "Error while restoring /data!" message, however it does the boot image and system fine but doesn't continue to cache and sd-ext because of the failed data. Whenever I boot it up, some of my apps are missing from the home screen and practically all of them are not working when I launch them (force close). I also get boot up error of Google+ force close, among a bunch of other issues. This is happening even when I try to restore an older backup as well. My device is not working state right now and although I can just restore the stock images to get it working again, it is urgent that I restore my data ASAP! I tried wiping several times and even using the non-touch 5.5.0.4 recovery to restore and same thing keeps happening.
Any help would be highly appreciated!
Please don't tell me my backup is corrupt
Update 1: Eventually I gave up and started from scratch but I have confirmed already this happened on a fresh backup as well, at this time we are trying to figure out what is causing this so I can go back to safely backing up and restoring backups.
Update 2: We have test builds of TWRP Recovery that may have resolved this issue! We need testers!
Please see this post: Link Here
Update 3: We have test builds of ClockworkMod Recovery 6 that may have resolved this issue as well! We need testers!
Please see this post: Link Here

Unfortunately I also have the same error today!

is your phone encrypted?
are you running stock recovery?
are you running a stock Rom?
have you done a factory reset yet?

Hi Spectre85,
My phone did fine yesterday, I was running AOPK Milestone 3 with FAUX123 kernel.
But when I woke up, my phone looked like it's battery was emtpy.
- When I plugged the phone with the charger, I started the phone again.
- Unfortunately my phone keep looping at the Google screen over and over.
So I pulled the battery and put the battery back again in the phone.
- I went to the bootloader and went to CWM recovery.
Deleted Data, Cache and Dalvike cache.
- Tried to retrieve my backup rom, but keep getting this "Error while restoring /data!" message.
I've tried to install other roms as well, but I still keep getting the bootloop at the Google screen.
Have you guys have any advice for me?

For me, no, no (CWM Touch 5.8.0.2), yes (stock rooted 4.0.4), no but my goal is to restore my data not erase it.

I had this happen to me before, what I did was flash a factory image through fast boot and it was fine after.

Thanks guys..I flashed the factory image through Fastboot mode and the phone works perfectly again! Too bad I lost all my data, but I'm happier that I have my phone fully functional again

You can't access your backup right? There's no way you can copy the file to your desktop?

I did copy it. I have full access to the file. Also, just fyi my goal here is not just to get to working state (I'm aware of the stock images) but to actually recover my data. My phone is currently on stock images completely blank and working now.

Fast boot flash the nand images just like u did the stock ones.

Nanadroid files can be flashed in fastboot? Are you sure? First time I'm hearing this. Doesn't fastboot need .img files? These are .tar files.

Open it up and see if its image...sorry all my recoveries use images.

I guess it depends on the recovery version you use. I remember older versions actually had .img files. However 5.5.0.4 and Touch 5.8.0.2 both have ext4.tar files.
Which version of recovery do you use?

If you have root, you can restore your data partition using Titanium Backup. Use "Export from Nandroid Backup" within TB, select the nandroid backup and then select all apps that you want to restore

Yes. Titanium Backup can restore all your system apps as well as downloaded apps from a nandroid backup. Not as clean as a nandroid restore from CWM but essentially the same thing. But try to see if Titanium Backup can extract your nandroid backup. It all depends on what exactly went wrong with your nandroid backup to begin with. I don't think it restores cache. So not sure about wallpaper.

You're right. This works great for restore data to select apps (got my notes and game saves back). I think the icon layout is held in the launcher settings, I'm about to try and restore the data to the launcher app and see what happens. I'm making a CWM backup of first of my current state (that's assuming this backup will actually work).
EDIT: Yes! That did it! Widgets position weren't saved but it's ok I only had a few so I manually put them back. Thank you! I never knew TB had the ability to work with nandroid backups.

I guess this now just leaves me figuring out what went wrong with the CWM backup. It happened twice (I have two backups from the same day that won't restore). Does anyone else use CWM Touch 5.8.0.2 and have successful backups? I would experiment to see if it works now but I don't want to end up with a corrupt backup and redo everything again.

Yes with me its the same thing my data its corrupt is even worse every time I do a nanobackup and restarted my phone the phone freezes on the boot logo and I have to go back to recovery trying to use my backups but I can't so I have to flash a new from again and start from the beginning again!!!! Anybody here has the same experience with that ???

So AGAIN, I'm having the same issue. This time on a recovery 5.5.0.4 that used to work for me when I originally got my phone. I think either my data partition might be too big or something but this really needs to fixed pronto. Anyone know how to contact Koush directly in regards to this matter?

Installing CM10 on Galaxy S3...first timer

This is my first custom flash off stock. I have actually had some experience flashing due to accidently flashing from LH9 to LG1, which doesn't work. So I had to install TWRP, do a factory reset, root it, and install LH9 from there.
But I plan on trying out CM10 and I have a few question.
A) Can I just flash CM10 in ROM Manager since it is built in?
B) How can I keep my apps, app data, account data, folders,settings...etc? I have both CWM Pro and Titanium Backup Pro installed.
C) Is there anything that is worse in CM10 than Touchwiz?
D) If I don't like CM10, I can go into CWM ROM Manager and just restore my Backup, correct?

To be honest you need to flash it and give a shot and see what you think, everybody loves something different.
Download from the cm10 build from the link in the xda thread and also get the 10/12 gapps.
Boot to recovery and make a NANDROID BACKUP!
When you install, you will need to do a full wipe.(Wipe Data/Wipe Cache/Wipe Dalvik/Format System in that order to be safe
Flash the cm10 rom and the flash the 10/12 gapps.
Then Reboot!
And enjoy the goodness!
I love CM10 or AOKP much better than TW, just my opinion.
Hope this helps!:cyclops:

QnA bud. Good to see you're starting to flash tho.

I've tried many, many ROMs on my S3 but I keep going back to CM10. Even though it's not a stable release for my model it's still awesome

Couldn't I just use ROM Manager since CM10 in on there and wipe data and cache?
Isn't the CWM ROM Manager backup a Nandroid?
How could I keep my apps and most my data...etc?
I appreciate your help, but I was knew how to do it in that way

Use Titanium to backup all your apps & data, boot to CWM recovery take a backup and install CM10 then restore your apps from Titanium, should be that easy!

Yeah, perhaps you guys don't use it, but my question remains. I've backed up using ROM Manager and transferred that image to my PC for an external copy. Couldn't I just install CM10 using ROM Manger as it is supported? Isn't that backup a NANdroid?
Or is it just not preferable?

Thanks for any help guys/

Can someone please answer my questions?

rom manager simply boots into recovery for you and makes the backup itself, etc. however, if you want to do more (wipe /system, etc) you need to go into recovery manually and do it.

So basically I should can ROM Manager to upgrade CM10 or restore, but not flash new ROMS?

i'm confused by your wording, sorry. rom manager would be suitable to your needs. it can install a rom for you, but it will only wipe data/factory reset. it will not wipe /system or dalvik cache like so many installation instructions say to do. rom manager can backup your rom and restore your backup.
so yes, you can use it if you choose to, but learning to use cwm would probably be easier in the long run than needing to rely on an app.

they are either on the internal sd card or one that you inserted into your phone. you won't lose any data on those.

Upgrading OS, do I need to Re-Root?

HI, this question is for the SGH-T989 specific, so some of the other answers I saw for other devices didn't really help me..
I recently just Rooted my phone!! Yay...I know, it's about time...Well, I'm trying to understand this stuff as I go about this journey...Basically I bought this phone once it came out..(Oct. 2011) I had the original Gingerbread 2.3.6 on it.. periodically getting the updates and installing them till I was on the ICS 4.0? whatever one came out in Aug-Sept 2012. With that said, I had some issues and wanted to go backwards, which I did successfully using ODIN..that's where I stayed for the last 5 months or so....
I actually had a hard time trying to get the super user 3.0.7 installed, so I had to use an older CWM (recovery-cmw-hercules.tar) which allowed me to install the SU...
I guess I needed to be on ICS in order for the latest one's to work. I now want to install ICS (the latest one) in order to try out some ROM's and was wondering:
1. Once I upgrade to ICS from GB, will I have to Root all over again?
2. Will my Nandroid back up still work if I restore it from back up in the Recovery Area? reinstalling all my apps and data for apps?
3. I'm using Titanium Back up too, so does this mean, that once I Nandroid back up, I can wipe it as many times as I want, I can just restore all my stuff using the Nandroid back up/ Restore?
I was going to use the last 2 of the followling: ClockworkMod Recovery 6.0.2.7 or ClockworkMod Touch Recovery 6.0.2.7 or TWRP Touch Recovery 2.4.1.0 again, as I tried them before, the Super User didn't work..But understand that these 2 will, when I update...
Basically, I don't want to loose all my Data and apps, but if I need to back them up, I will, just in case...

1. I'm 99% sure u will lose root. BUT that's my opinion and you need the fact so wait till someone else answers. However I don't see the harm in re-rooting. As stated before - quite simple.
2. No if u restore a nandroid back up u would undo ur progress and go back to gingerbread - the exact state in which you created the backup.
3. If you are using Titanium and all u need backed up is ur apps and data then ur set. Doing a nandroid backup is just a safety net in case ur update to ICS goes wrong. If your update goes well then that backup is now useless. If it goes wrong then u restore your backup to gingerbread and try the whole process again. So in summary - Nandroid for system backup , Titanium for apps and data. Also, as long as you don't wipe ur internal storage or SD card u will always have ur titanium back ups saved and therefore can wipe in recovery as much as u want since it only effects the system partition.
I see your confusion lies in differentiating between a nandroid backup and apps/data backup and what each one is for. Hope I cleared it up. Good luck

bootloop recovery from twrp backup?

Hi all,
So I've gotten myself into a bootloop by messing with permissions/ownership in the /data/ directory. I would like to recover by losing as little data/settings as possible (I only rooted with chainfire AutoRoot anyway, so stock, rooted, ROM).
1) I have a few months-old TWRP backup, is it possible to extract what I need from this?
2) If not, what rom is my best bet to flash to recover a stock, rooted ROM, with my old data? I tried re-flashing CF-AutoRoot, but it didn't do anything...
Thanks for any help

Well first things first.
1. Did you install a custom ROM?
2.or backup your rooted stock?
3. Did you already do a full wipe
(Data/factory reset)
4. If you didn't do step 3 but you did step 1...I would advise a dirty flash of the custom ROM that you had
4. If only step two is applicable I only see two possible routes
4.1a. Use Odin to update twrp or download a new custom stock ROM and flash that so you can boot...then try and update twrp to the newest version and then try to flash your backup to see if it was a version problem
OR
4.1b. Start from scratch but I would advise using cwm from now on. twrp to my knowledge isn't updated as frequently as cwm
Hope that helps. Feel free to pm

Hi! Thanks for the reply!
I have not done a data wipe, and I would like not to...
I used CF-AutoRoot, I'm not 100% sure if this counts as flashing a custom ROM or not, it's supposed to keep stock ROM but give you SU. I have tried repeating CF-AutoRoot again, but it doesn't seem to fix the problem...
The only backup I have is of the full phone image, which I don't want to restore since it is months old and I would lose data... Is there a way to only restore selected files from the backup? So far I have restored CWM and can access an adb shell...
Thanks

OK so basically as far as I know you are Sol on your original rom ....that's why I always flash a custom ROM but the data stored should still be on your internal (pictures, videos, things of that nature). your app data and accounts however is not...for example games and such...I would advise titanium backup and do a backup of all your app data at least once a week from now on
Sent from my GT-N7105 using Tapatalk

Agreed ...you are going to lose data in this case ...as you will need a restore of your old backup ..or fresh install of a new rom ...
Backups are king when playing with device roms and recoveries etcetera ..g

Backup

Hey there!
I have a question? What's the best option for backing up my whole device? I want to flash CM 12.1 but I need TWRP for that, and for TWRP, I need to unlock my bootloader, which (according to people here) means to wipe my data and apps.
If I use the Backup app pre installed in my phone, will I be able to restore if say... I re-flash my stock ASUS ZenUI ROM again?

Yes you can restore from the backup using the stock Asus backup app if you decide to go back too stock. If you stick with cm12.1 then I would use titanium backup from the play store to backup and restore apps from a custom rom. However titanium backup also works with the stock rom but if it restores stock apps on a custom rom they will likely crash like mad.
Fun note when I unlocked my bootloader using the unofficial method it didn't wipe my data so I didn't need to restore any app backups. As always backup anything you might need just in case something goes wrong and you need to restore anything.
Pro tip, when doing backups on a phone like that zenfone 2 if you can backup to a removable sdcard cause if something goes wrong and you cant power on your phone you will always be able to access the backups using a sdcard reader.
