Unlock/Root/Custom Rom warranty question

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.

[Q] How to update rooted Galaxy Note 2 while keeping all installed apps

Hello.
If I have a T-Mobile Samsung Galaxy Note 2 that is rooted and have CWM and have some apps installed on it, How can I update it's official firmware while keeping it rooted and keeping all of my apps the way it was before?
Sorry if question is easy or repetitive. I couldn't find the answer.
Thank you.

rooting or unrooting doesn't modify your apps, but if you're worried, while you're still rooted, I would backup all your apps using Titanium Backup. Then if something does happen you can restore it back. That is of course, once you unroot, update, and reroot again.

Download full rom here http://www.sammobile.com/firmware/?page=3&model=SGH-T889&pcode=0&os=1&type=1#firmware then use mobile odin to install it, injecting root at the same time.

I have no problem retaining ALL data after updated with Kies. Regaining root is no sweat as well.
But remember to use Triangle Away to reset flash counter.

I would like to try doing this will mobile odin. Could you provide a little more detail. Did you put file the internal sdcard? Also did you do a wipe of any partition? Does wiping data and cache option also wipe internal sdcard.
Thanks!

In mobile odin you have the option of wiping dalvik and cache, it wont wipe anything else. I had an external sd card that I always put it on. Very easy to do and it works perfectly. Just make sure you check mark to install ever root, super su and mobile odin.

used mobile odin pro

Used mobile odin pro. Worked like a charm! Recovered root, all downloaded apps and settings were intact via Titanium Backup. One thing, if you want to restore the state of a rom specific app (like the calendar), Titanium will warn you that you could have errors because you have a different rom. For this case I restored data and then calander showed all appointments so good to go here. Also, I had used the xposed installer to modify multiview such that I could run all apps in multiview. Worked fine with this rom. One curious thing, if I now check for device software updates I no longer get the message that my device is "modified" and am ineligible for updates. This is nice! had thought that you couldn't avoid this even if you used triangle away. Thanks again!

How do I re-root my Tmo Note 2 using heimdall? I was rooted, then updated to 4.3 via Kies. I lost root, and do not know if I am supposed to follow the same steps when I rooted my Note 2 while it was running 4.1.2. Any help will be greatly appreciated. Thanks!

[Q] Possible to flash only kernel without wiping?

Is it possible to unlock the phone and flash only the kernel without wiping any data?
I would like to have benefits of the better performance from the new kernels but to not to have to reinstall everything.

From my knowledge, I don't think it's possible. An unlock requires a factory reset.

I think its not possible to unlock the phone without deleting data partition (for security reasons). How ever you can still backup all your apps+data with apps like Go Backup Pro(its free from market), but not sure if it will require rooting.
Other option: backup your data with adb pull/push commands
if you run out of options: try flashing unlocktoken from RUU mode(it avoids the warning screen, but I think it will still delete the data)

Well that is a shame.
I really wanted to make this as easy as possible.

You can try the app called carbon. Its free and does not require root. After the backup unlock the bootloader and restore the backup. Then you are able to flash different kernels.

Root/unlock bootloader without losing data

Hi there
I'm stuck with this o2 UK M8 4.4.2 for a while, with none of my old backed up apps or data on it (need root for that). I need to unlock the bootloader and then root to restore... Easy enough. But I cannot afford a full wipe at present. All the data, settings and apps are too crucial
Is there any way to unlock the bootloader (root) without losing my data?
Or any workaround?
Thanks in advance!

Try to backup with the app called helium. Then unlock and root, restore backup if there are things missing.

[Q] Questions on after rooting

Ok so I decided to root my VS985 G3. Mainly for better battery as of right now and to run some root apps. Running Lollipop 5.0.1. So far I have userSU and TitaniumBackup installed. I know the greatest thing with root is custom ROMs, but I'm not at that point yet. With just root here are some question I have as far as a noob with this goes.
1. Do I just do back ups with TI or do I still use the stock LG backup app?
2. In the event that I need to do a system restore. Do I need to uninstall root with userSU first then do a regular system restore with the power/vol down button or can I do it with the root still enabled?
3. Until I get comfortable being rooted and how things work I'm not going to do a custom ROM. However being a 25 yr exp computer tech tinkering is in my blood so I know at some point I will do it. With just root do I need to do a TWRP nandroid backup now or wait till I get ready for a custom ROM?
Thanks for helping guys! I am a IOS convert and am loving the Droid life.

1. Backup with Titanium Backup. It does a more thorough job
2. I dont get your question. Under what circumstance do you want to do a system restore? If you make a system backup while rooted when you restore the backup you will still be rooted?
3. You only make a backup of your system using TWRP or Nandroid Backup if you are going to be playing around with the system folder or if you are install custom rom
Oh yeah and by the way once you root they will know that you rooted your phone regardless of whether supersu is present on the phone. They do this by looking at the LG RCT menu in service settings

So annoying that warranty is void when rooting. Oh well, if I have an issue down the road, hopefully my carrier doesn't look at that menu.
(though, aside from an issue with the internal storage on a Galaxy S i9000m, I've never had to send in a phone for warranty)

Actually, removing root and bringing the device to original state is as easy as flashing an official rom. No traces of root left.

My question there was looking at "IF" I wanted to do a system restore would I need to unroot first or restore as normal then re root. Thinking I loose root when I do a factory restore. Just didn't know if I needed to unroot or not before doing the restore. With my VS985 it will have a few kninks every now and then that doing a restore seems to help fix. Maybe a hardware defect, but nothing that I would send back for a replacement for. Some of those kinks maybe verizon problems too, but restore seems to fix them for a time for me.

If what you mean "restore" is to wipe Data/Cache/Dalvik, then you don't need to unroot. After the wipe, you will lose all your installed app, but you start with a clean slate. The root is still there, and you can install SuperSU to get access to it.
To install a custom ROM, you need to install TWRP first. However, you cannot do it from L. You need to first downgrade it back to 10b using the TOT flash. Stomp root it and install TWRP manager from Play store. From TWRP manager you can install TWRP to your VS985. After that, you can flash custom ROM from TWRP.
