[Q] Reflash stock 4.3 without losing data - Samsung Galaxy Nexus

Hey,
my GNex (GSM version) is running very, very slow at the moment. I already tried cleaning the cache and using LagFix, but as fstrim is already included in 4.3, that shouldn't be a problem.
I'm running stock 4.3, rooted but no tweaks or anything applied, root is only for Titanium Backup. My recovery is ClockworkMod 6.0.3.6 non-touch.
So what I'm trying to do is to reflash the stock image as provided by Google, without loosing data, and I'm not sure which steps I should take and before I lose anything I wanted to check back with you if I miss anything.
So, here is how I would do it:
1: Unlock bootloader. It has been unlocked to root the phone, but is locked with the BootUnlocker app. (We don't wanna lose the unlocked bootloader, right?)
2: Nandroid backup. Can't hurt, I guess. Should not really be needed, but better safe than sorry.
3: Run a full Titanium Backup. Store it somewhere safe (not on the phone.)
4: Backup all the data from the device. Problem here is, Windows Explorer crashes if there are many files it should copy, so has anybody a idea how to overcome this?
5: Download factory image and flash it. There are enough tutorials on that around here.
6: Booting the device first time, but let it be offline and not adding a google account. (Is that right?)
7: Reroot the device. Also enough tutorials.
8: Let Titanium Backup work its magic.
9: Restore data to internal storage.
10: Add google-account.
So, is that right, the right order, did I miss anything? Thanks for your thoughts on this!

Total Backup solution needed

I need to do a total backup of my Desire, as I have the Android Market problem, and I have tried everyrthing and I mean everything trying to fix it without having to do a factory reset. So please dont give me tips on how to fix it.
What I do need information on is how I can totaly backup my desire, meaning
contacts
sms
google maps starred loactions
and all downloaded apps with their settign are backed up
I am aware that there are things on the Android market that I can download to backup different bits at a time, but I cant use Android Market app to download anything so I need to get apps that I can put on the desire from my pc.
Any ideas would be very helpful.
My desire is running Android 2.2 and has not been rooted or modded in any way.

Titanium backup is not necessary - after rooting just use Nandroid backup from recovery.
Is there a way of backing up app data without rooting?
i.e. I want to be able to back up Angry Birds data so if I factory reset I can reinstall all my scores

Titanium Backup is a more flexible solution.
I don't see how backing up the whole nandroid and restoring it would fix anything, the phone would be in the exact same state.
Nothing that doesn't involve rooting to save data?
No way to do that. The data is simply saved in a partition that normal users can't access. So root is actually necessary in this case. Pretty easy and harmless, especially since you can unroot if you want to.
I thought so - I also assume to restore backups you'd need to be rooted too - silly - you'd think that some way to backup app data would be fairly common (to non-rooted bog standard users)...

Actually, I wouldnt call it exactly harmless. Depends on how you've gone about rooting it and what precautions you've taken.
If you're a newbie, ensure the following before you root:
Make a goldcard-Absolutely essential if you have an SLCD Desire, since RUUs are dificult to find for unrooting, if you're branded
Ensure that an RUU for your country is available, or a generic one which is sure to work.

There are apps to backup certain things like SMS and Application Installations (without data), which can work without being rooted. If you want the restoration to mimic the previous state of that app with data, then you need to access the system as root.
I backed up using Titanium backup after using unrevoked to root my device.
I now have a problem doing a OTA update from T-mobile/HTC (update 2.12.110.4)
It downloads then asks me to install to which I cay yes, it reboots and just sits at a screen. when I press the power button its shows the clockworkmod recovery v2.5.0.7
and says verfication signature failed and lets me reboot and doesnt install the update.
What is this?

OTA updates dont (usually) work after rooting. In most Rooted ROMs they wont download. In some they do, and wont update. OTA are like RUUs. They try to upgrade the factory version of the software and should be used only on non-rooted Desires. Anyway I dont see why you need them. In case you're rooted, the latest version of your custom ROMs would be better than OTAs..
How would I go back to the standard rom - is it by doing a factory reset?

If you mean you want to take your phone back to what it was when you first got it..This is called reverting to Stock
If you have rooted since you got the phone, and have not put on a custom ROM like Cyanogen, Aurax or LeeDroid, your phone is now basically Rooted Stock..In this case, if you just want to remove all the custom apps and data, you can do a factory reset..This does not remove the rooting. The app Superuser Manager will still be in your phone menu, and Recovery ROM-Clockworkmod/Amon Ra will still be on the phone. In brief, the rooting process is apparent to service engineers.
If you have put on a custom ROM like Cyanogen, Aurax or LeeDroid after rooting, if you just want to get your phone to the HTC look, you can flash a Stock based ROM-Froyo or Non Froyo (Just search for "Stock rooted ROM"). This will get you the HTC sense interface.
But if your purpose is to take phone back for warranty purpose and don't want them to know you've rooted it, you need to flash an RUU over your current setup. This will remove rooting process and get it back to factory setup.

So doing a factory reset wont remove the clockworkmod from my phone then?
How would I go about doing a RUU as I dont really need my phone rooted generally, and really only needed it for the Titanium backup?
Speaking of Titanium backup once I do the RUU I'm guessing I wont be able to restore my titanium backup bits, as I wont have root access anymore?

You just got your wish answered! Check out this thread. Apparently Titanium can be run in a Temporary Root mode, thus allowing us to restore items even after unrooting!
So doing a factory reset wont remove the clockworkmod from my phone then? No, it wont!

[Q] ESPRIMG.zip update in the Bootloader wipes phone?

I'm about to finish this rooting process to put a custom rom on my brothers phone, but I want to be sure he won't lose all of his data if I do the ESPRIMG.zip update...I'm just trying to play it safe before he hates me for losing all his data
If anyone can verify this for me, I'd greatly appreciate it. I don't want to mess this up if I can avoid it.
Using the exploid method, I got to the part where you get the # in the adb shell, indicating root. However, titanium backup and such apps would not yet run, so I had to continue to make the root permanent with full access(or so I understand), and have now found myself at this step. If this zip only enables us to flash clockwork without wiping all the data on the phone, that would be awesome. I just want to make sure that is true...I haven't seen the answer anywhere else. Thanks for the help guys!
I wouldn't think anything would be wiped until you flash a new rom or do a wipe yourself... but don't quote me on that... I've only rooted 3 devices and the Slide was back in December, haha. D:
Which leads me to a kind of on-topic question... How do people back up their stuff the first time around if they're not rooted? I'm sure it's something simple. I just kinda made a list of the stuff I had.
If it's something extraordinarily obvious, I'm sorry it's 5AM anddd... I should probably know anyways. xD

This is what I'm wondering. I've rooted a G1, G2, and nook color before (although the NC is completely automated and required no work really, as there was nothing to back up the first time around). On the G1, it was my first device obviously and I lost all my data when wiping and flashing a custom rom. In the G2 process, I was able to get apps like Ti Backup to run on the stock rom, so I was able to back up all my apps and data.
On this one, it's a bit different (at least for now), I want to know if performing that update in the bootloader will put an entirely different image on my phone, meaning I'd lose all the data that's currently on there.
It's not so much the apps, but all the application data that I'm worried about losing without warning him first...I don't want him to have to repeat all his work to get to the same spot he's currently at in angry birds or something
Its going to wipe the phone. How to back up data? Idk.

I just did this myself, so take a noob's word for what it's worth.
Yes it will wipe the phone IF you tell it to do the update. If you want to back up your phone you first need to put ClockworkMod Recovery on your SD card and name it simply update.zip. When you load into the boot loader (Vol down + Power) select "Recovery" then something about "Apply from SD: Update.zip" and you will get into ClockworkMod Recovery where you can then do a Nandroid back up of your phone.

It completely wipes the phone. It REPLACES SPL, radio, recovery, rom, etc with the factory spec so the phone will be exactly as it was when first pulled out of the box.
Contacts, calendar, etc should be backed up to google. Apps can be downloaded again from the market and should be auto restored on sign-in to google.
Personal settings and data like texts, call logs, etc are gone though unless you use a program like Titanium Backup to save them.
The other thing you could do is root the stock rom, make a nandroid backup before flashing a custom rom and then if he wants to go back all he has to do is restore the nandroid backup and unroot with all his data preserved.
All right this is what i was suspecting. Is there any way to run titanium backup on the stock rom without wiping it first?

What do you mean? Titanium Backup requires root. You can use it in your custom rom to backup everything you want, then restore, reroot, then download titanium backup again and restore the data from your sdcard. If that doesn't answer your question please elaborate on what you are trying to accomplish so that I can help.
Where are you now? What steps did you take to get there? Where are you trying to get to and why?
EDIT - I've had an mt3g and an mt4g but never an espresso so i'm slightly out of my element. I reread the first post and it appears you have root but for whatever reason titanium isn't granted root access. Do you have superuser permissions installed? It can be installed from the market as long as you have root access.
Once you have clockwork (or amon ra) recovery installed you can make a nandroid backup of his stock rom without rooting it, but carrying all the data over to the new rom will require an app such as titanium or mybackup (free 30 day trial) from the market.
Hope that helps.
I guess it WILL then!
Yeah, this was the first device I rooted, so I just sorta flew through it. I was glad that it got rooted and I could put a rom on, so the loss of data wasn't TOO big to me.
And I've lost Angry Birds like... 4 times now, haha.

I am aware of all of that.
What I've done is use the exploid method to root until you get to the "#" prompt in the adb shell, after toggling wifi and running ./exploid twice. Then to continue in order to flash a custom rom, I've got to perform the update from the bootloader with ESPRIMG.zip. All I'm asking is that since I do have root through the exploid method, can I run Titanium Backup BEFORE I flash a custom rom, since technically it is possible to gain root access before flashing custom roms. I tried installing the app but it could not properly gain the access it needed. I think this probably has something to do with no superuser app being installed either.
Does it make sense what I'm asking? Thanks guys.

Yeah I think so. I'll take a look at the root guide but if you have # in Terminal then you should have root. Try installing superuser and see what happens. Do you have a custom recovery installed yet? I think you'll need that to install superuser.
Why didn't you just try SuperOneClick? Much easier than all this.

The # in terminal disappears as soon as I try to exit, and whatever work you've done resets upon a reboot.
I don't have clockwork installed as of yet, because the guide says I've got to update the ESPRIMG.zip through the bootloader before I can do that. I'll try flashing clockwork first and installing superuser before I do anything else.
Does a one click root exist for the slide? I thought that it wasn't possible at this time. If that's the case I'm interested as long as it allows me to run Ti Backup and such and flash clockwork with s-off to do some backups before I go ahead and flash cyanogenmod. Thanks.
EDIT: As expected, can't flash clockwork update without flashing the ESPRIMG.zip update. If I can't run Titanium, it'd be nice to get a couple files out of /data/data before doing the wipe. I tried an adb pull which would not work from the /data partition. With the # prompt in terminal, I wanted to copy some of these files, but the "cp" command doesn't seem to work in terminal, but "mv" and "rm" do. Any way to copy files from within the adb shell? If I could move them to the SD card it would be nice.

are you rooted? if not...
http://www.jonamerica.com/technology/updated-root-the-htc-droid-incredible/
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.

Best way to unroot and restore to stock to get OTA updates?

I finally figured out how to root my phone (thank Sithis)
I just flashed TWRP and SuperSU. Sadly I was only able to recover a handful of photos from my whack phone factory resetting itself. (my only reasoning for rooting, to use data recovery. I only found DiskDigger. didn't do that great sadly)
I think I MIGHT have picked up some sort of malware or virus; not entirely positive but since rooting, my phones camera flash randomly goes off as if something is taking pictures. I have GO Security and 360 Security downloaded and it didn't find anything. I don't know how thorough those apps are but hopefully they would have picked up any malicious thing invading my phone.
I know there is an unrooting option through the SuperSU app. Again, I don't know how "complete" of an unrooting that'd be.
I honestly wish I had the links I used to download TWRP and SuperSU. Maybe to see if anyone could figure out if they were legit.
I want to unroot, then factory reset. Would I have to flash a stock ROM before hitting the 'unroot' button? How would all this work? Anyone figure out how to get OTA updates after a complete unroot?
If anyone could point me in the correct direction I'd be thankful. I just don't want to deal with the security risks of a rooted phone and would like it back to stock. If I could do that without flashing a ROM to my phone that'd be great.
Since I couldn't find anything of the sorts for my N910PVPS4DPE2.
[edit: please delete post and redirect me if already asked and solved (within 2016)]
You could press that un-root button now but most likely you cannot take the next OTA without flashing the stock tar in Odin. Modifying some partitions will break OTA updates. Having custom recovery won't work.
I don't think it's ever been established as fact but in theory, you could root a stock phone with Chainfire's CF AutoRoot for Note 4 in Odin. Leaving as that root installer rooted, you could un-root later for OTA update within SuperSU application. It would prompt you to restore both kernel and recovery with the original stock ones and then reboot. *But* if Samsung flags modified read only partitions as being modified, even if modified temporarily, OTA would still be denied for modified status trip. Dunno if anyone has confirmed the theory on our phone or not.
To answer your question, I think you'll have to flash the stock tar in Odin to restore your OTA capability. I would recommend you press the full un-root. You can restore the original kernel, if it was stock, at prompt. But most likely you cannot restore the original recovery if flashed manually. You'll need to flash the stock tar again to both restore read only partitions and stock recovery. If you forget to to perform full un-root, I think factory reset will be enough to clear root and remnants with a stock tar flash. (Stock tar flash should wipe internal memory but to be sure, you could wipe that too).
It's up to you, you could wait until the next OTA to flash the stock tar.
For your camera issue, it might just be enough to factory reset for now.
Have you considered Titanium Backup to backup and restore applications? A lot of rooted users use that. I'm not sure copying and restoring a disk would mesh with Android package id used to link data to original application with proper linking and ownership. I do know that Titanium Backup complies with that. If the package id gets skewed, restoring data may not work as expected. Something to check or confirm beforehand. Just a suggestion.

Thanks for the reply man!
Looking over it, it seems like a true hassle to go through finding the stock ROM for my phone and unrooting and that whole process. I think I'll stick with the root for now. I have a couple more questions if you don't mind:
1) If I kept root, could I perform a factory reset without it screwing up the root? I think there's a 'factory reset' option when I boot into TWRP. I would just like to know if it'd remove TWRP/SuperSU. I have heard a lot about Titanium Backup so I will be giving that a try before doing so!
2) Any chance you'd know if when the new OTA comes out, they will have it flashable for my N910PVPS4DPE2? I'm relatively new to all of this and I know if I flashed something not meant for my exact device; I might as well slap some cement on my new Brick Note 4. I've never seen any ROMs/Mods that say 'For N910PVPS4DPE2' specifically. Maybe I'm being overly cautious and don't have all the new lingo down. So, are there ROMs and mods for my phone that I'm just completely overlooking?
Thanks again for helpin a newbie out!
Stock tars are here:

A stock ROM with system based root that isn't easily wiped or lost is here:
http://forum.xda-developers.com/showpost.php?p=63028063&postcount=1
I believe factory reset still un-roots systemless root. There was a script that you may have been prompted to install to keep root but I'm not familiar with its retention capability because I use and prefer system based root in the ROM above. You can factory reset the ROM above without losing root.
You would need root for titanium backup. I would recommend factory reset and install the beta 3 ROM. You may not like the missing voicemail app. I use the long press of 1 key in dialer for voicemail. You could just save the apk and install with apk installer by tapping its file with root browser or MyFiles and install. But extract or copy and paste with root browser from current ROM.
OTA's can be expected nearly monthly now. Tars release a bit behind the OTA.

Question about a full backup and rooting

Hi,
I recently tried a custom rom on my old phone and it worked pretty well. I liked the OS and now want to also do that on my current phone. But i do still have a few questions i hope you can help me with.
- Can i make a full backup of my phone (with app data) to my PC or maybe to my old phone? I am currently not rooted and tried helium backup but saw that sadly not all apps allow a backup.
- I know about titanium backup. Is there some way (if the above cant be done) i can root my phone without wiping the phone? So i can then use titanium backup to make a proper backup with data, then install the custom rom and after restore the apps+data.
In short: I hope i can somehow make a full backup with app data so i can install the custom rom and restore my app data again.
Looking forward to your replies.
Thanks in advance.
Nothing? No one ? =(
To root you need to unlock the bootloader, which wipes all user data. So you can't use root to backup your data. This is why I unlock the bootloader immediately after getting a phone.
You can try an adb backup though.

Thank you for your reply and thx for the tip. Ill be doing that too from now on when i get a phone.
As long as i can make a full backup with abd (with app data), Im fine with wiping to root it. But just wanted to make sure i can get app data back after the root process.
Do you happen to have a link to a proper backup using abd guide?
Thanks
no

Well with a few side searches i was able to open the cmd (admin), do a adb devices (which found a device) and then run the app + data command.
('adb backup -apk -shared -all -system -f C:\backup.ab')
I saw the screen on my phone to start it, which i did but it stays on Shared Storage (where before this mentioned the apk's that were being backed up). This is taking pretty long (as in hours). Is this normal or did something went wrong and is it stuck on that part?
Edit (Update): I stopped the whole thing and tried again. Now it finished in about 10 - 15 min. I did get a message "backup finished". However in the folder i gave up, there is nothing to see. folder is still empty
Edit2 (update): Found the backup.ab file. Apparently it was in a different folder i thought it would be. So if i then also make a copy of the internal storage and do this command, i should be good right? After doing that, unlock and root, i can use the 'adb restore C:\backup.ab' and have all apps + app data back as it was before the unlock/root ?
no

In a sense. Yes, but you might wanna read some threads about that first.. Otherwise. No one would wanna go back after unlocking his phone. Since restoring a backup from a locked phone on an unlocked phone can cause some issues.

I'm not really sure what you mean though.
If i unlock my phone with my code and then make the backup with adb and just in case, a copy of my internal storage, can't i use restore on the unlocked/rooted phone to have the apps + their data back and use them again ?
no

No you can't. It will brick your device. The backup can only be used when your phone is still locked. So it is basically not needed at all.

So you are saying that there is no possibility to backup my apps+data, unlock/root/custom rom, and then restore my apps+data at all?
That was some what the question of my first post.
So its either, fully wipe with everything lost, then root etc. etc. or just keep it the way i have it now?
no

The normal procedure is as follows:
After an unlock.- your data always gets formatted. So a backup is totally wasted time.
The backup isn't wasted time - if it is done after unlocking your phone, while it still has stock rom.
In case flashing goes wrong, make the backup while not having flashed twro etc at all.
You don't have to wipe anything if you just want root, since the phone will reset-wipe your data on its very own.
Just unlock it, let it reboot, Flash twrp, install root zip file. Reboot
In case of flashing a custom rom. Flash twrp, boot to twrp. Use the Reboot menu and reboot again into recovery
Reboot->Recovery (in twrp menu).
Then Wipe-> Factory Reset
Wipe-> Advanced Wipe-> Wipe System partition only
Wipe-> Advanced wipe-> select Data partition-> Change file system to ext4
Reboot Menu in TWRP->Recovery
Wipe Dalvik and Cache
Flash Rom
Flash Gapps if not stated otherwise in Instructions of Rom Thread
Flash Magisk or SUperSu , depends if you want root or not. If you don'T want encryption on older Roms, flash one of the two.
Encryption will later on be optional through Phone Security Options.
Wipe dalvik and cache.
Reboot.
Wait a bit.
Setup phone, done.

Yes but as you mentioned, unlocking means a full wipe. And i cant restore apps + their data from a stock phone backup to an unlocked phone as it can cause issues.
In my very first post i asked if i could make a backup of the apps + their data to restore them after unlocking/rooting/custom rom or whatever. Simple answer then is no.
So i either have to just wipe my phone and basically start all over, only unlock/root etc etc first.
Or just keep my phone stock like how it is now and just do nothing and wait until i get a new phone (which will be in a long time still)
