[Q] Doubts about unlocking bootloader and rooting

Hi guys,
I've been playing around with my Nexus S for about 3 weeks and I've decided to root it, but I have some question, I've been searching the answers in older posts but it's not quite clear yet, hope you can help me.
When I unlocked the bootloader, what kind of data will be wiped? It's just the SD card or also all the apps I've already downloaded? what about SMS, pictures and videos?
Is there anyway I can backup that data considering I haven't root it yet???
Thanks in advance.

dont do it man. i just got my phone yesterday at 1 pm and its now 12am and its bricked by lack of support from the cummunity. i studyied and studied 4 around 10 hours. then bricked my device. and i have a good idea i wont be getting a replacement this time

lol what? its nobodys fault but your own. all the resources are available, just because somebody isnt responding to your threads and holding your hand to restore a nandriod backup doesnt make it a "lack of a community".. and your phone isn't bricked, it can be recovered but you are too close-minded and cant install Clockwork Recovery / get drivers working
The data that will be wiped are most likely your SMS/settings/etc. This is standard procedure. And its something you'll go through a lot when you are using custom ROMs.

There are complete instructions for rooting, unrooting and unbricking your phone. It's all here in the forums, and many other places, you just have to look and learn. I read for two weeks before I unlocked and loaded a ROM into my NS.
If you don't have a need to root your phone I wouldn't do it just because you can. I wanted to run the Voodoo app so I had to root and load a ROM. It took a little while but it was painless and I liked learning about the Android system.
You do have to backup your app and your SD, but that was the easy part.

It's close to impossible to brick a nexus device. They purposely come with totally open boot loaders specifically for that purpose!

its not only Nexus devices but like I said people are using the term brick wrong. with these new phones coming out, a lot of them are hard to brick.
if you're phone is able to get into recovery/start/download mode (odin not popular but still an option)/bootloader then its not bricked.
if its unable to start in any form or way.. its considered a brick. please stop using the term in its wrong definition.
"brick" describes a device that cannot function in any capacity (such as a device with damaged firmware)
In the strictest sense of the term, bricking must imply that software error has rendered the device completely unrecoverable without some hardware replacement.

I think guys you have lost focus about my question, it's not about how to root (there is a lot of info about), it's about what kind of data will be wiped and how to back it up

What's the best way to do it? It's there an app or I have to day it by myself?

Make a nandroid backup first and foremost! Use Titanium Backup to make a backup of all your apps. If you want a backup of your sms, go sms pro really does a great job of that. Dont forget your contacts as well! Then copy your sd card and place it on the hard drive of your computer. When you unlock the bootloader, it does wipe your sd card. Once your unlocked and rooted, you should be able to restore everything once you replace the copy of your sd card back on the phone. Coming over from a Vibrant, I was nervous about rooting the phone but its an easy process. Just take your time and do lots of reading! Hope this helps!

Thenx, but I still have one doubt, if I haven't root my phone yet, will nandroid or titanium work?

Woops..yeah, your right there. Too quick to reply. I followed this method here..
http://forum.xda-developers.com/showthread.php?t=895545
and had no problems. Once you get unlocked/rooted and clockwork recovery, then you can make the fore mentioned backups. Export your contacts to the sd card then copy the sd card to the hard drive of your computer before unlocking the boot loader. I do not think apps get affected during the sd wipe unless you have them stored there.

isnt that what we call a brick? ive had issues on a galaxy s with this game issue. htc devices i can fly through the root procedure but i got this 1 rooted, tried reflashing to stock and the phone wont turn on at all.
may i suggest a noob proof guide|? i postted 1 in the htc desire forum and people love it. yesterday i returned a moto xoom because ti was overheating , got a nexus s and 2day il b returning that because it wont turn on. can any1 help me think of a good idea i can tell the future shop return people?

you are forced to lose your data to initially root your device. then after that point, you can always create backups and never lose data again while you switch between ROMs and flashing etc. but i think to initially root, you have to lose everything. not the sd card though.

Do keep in mind, we don't have an i9020 or an i9023, we have an i9020A So the instruction out there all need to take that into considerations. I rooted mine fine with no "Bricking" I had to follow the instruction for the i9023, but it worked. I figure it took me all of 1 minute to root my phone. Admitedly, the "One click root" for the Galaxy series was easier.
I try to make it a point to never be the "First" person to do something on their phone. Much safer that way.
I also find it very unusual that you've managed to brick two phones, I've also had the pleasure of owning the telus fascinate, and not once did i get it bricked, I tried Bionics, CM7, Darky's and a bunch of other ones. Just never mess with the boot loader. When you went back to stock, did you make sure it was a stock ROM for the I9020A?
Have you tried connecting the USB to a computer, holding the volume up (or in the case of the galaxy, both up and down) While powering on the device? I've had to use that a few times to recover my galaxy (Thank you odin!!).
Now in regards to the OP, I would recommend using a program like Ti to back everything up, unlock the bootloader then restore from Ti, it's a little more hassel, but you can pretty much keep your settings and data. Personally, i rooted my phone before configuring a single thing on it.

there is no way to make a good backup without rooting.
basically yes, you will lose all your settings
there are a few apps you can use to backup your apk before unlocing/rooting the phone.
look for App admin on market https://market.android.com/details?id=az.mecid.appadmin&feature=search_result
the stuff backed to SD does not get wiped
only the internal storage stuff

i took about 12 minutes total to unlock my bootloader, flash clockwork, and flash a custom rom. its not difficult if you pay attention to what you read. youre phone is not bricked. btw, i read your threads. if you werent so demanding, i would have helped. use the pdanet website the next time you need to install the proper driver, and follow the directions that they give you.

When I unlocked I used Astro to back up my apps, I turned on the Google data sync to back up my contacts and I did a back up of my SD on my computer.
When the unlock and recovery was done NS asked for my Google account then it restored all my contacts, Astro restored all my apps and I restored my files from my computer. A few steps but not difficult at all.
You will have to redo your accounts and data, and maybe an app or two won't load but the market will show them installed, just reinstall any that didn't.
Make sure you follow the directions properly in the forum. I had to use two computers to get it to work, but it did work and nothing was damaged.
With all that said.... This was the first time I have ever owned or altered an Android phone. Sure I was nervous... Now I'm hooked.. haha
I wound up using NSCollab .17 so far so good..

First thing I did when I got my phone was fastboot oem unlock.
Even if you don't want to root, use another ROM. Fastboot unlock it so your data doesn't get wiped.
If your hardware and everything seems okay, then flash Clockwork Recovery and do a nandroid backup so you can restore to pre-flashing point if you need it for OEM purposes.
Afterwards, go crazy and flash like theres no tomorrow and find something that you'll like.
And agreed with simms. You've made so made so many threads about this. I would help you step by step but I've been busy so I can't do that anymore. But if you search, you'll find about two or three threads where I did help somebody get their phone to a working state.
The basic idea is... if your phone doesn't boot but you can get to recovery.
- Download a ROM or Nandroid backup
- Install USB drivers
- Fastboot oem unlock (if you haven't)
- fastboot flash recovery recovery.img (or whatever the recovery.img is named) should be in /sdk/tools
- reboot into recovery (adb reboot recovery)
- mount and storage: mount USB, put the nandroid backup or ROM onto phone
- nandroid restore or flash a ROM (wipe factory,dalvik,cache --> flash ROM (if its CM7.. flash gapps afterwards)
- reboot
your phone boots. alternatively, you can use Odin but thats not a popular method but the choice is available if you wish to go towards that approach

in the worse worse possible case scenario there is always ODIN to the rescue

Why did you guys wait at all?
Once i got the phone i immediately plugged it into my computer and rooted it.

How to do nandroid like backup on a unrooted stock phone?

My phone went through the boot loop and I had to factory reset and lose everything this morning. OK, my bad for not backing up, though I did back up some things like photos.
I want to ensure my other phone doesn't have this issue -- and the only 'full backup' I'm aware of (nandroid) requires the unlocked bootloader which this phone does not have. So what is the best way for me to back up this phone PRIOR to unlocking bootloader and forcing a factory refresh?
I know I can back up photos and other stuff relatively easy, but these things I had to restore on my phone manually:
Texts (Use SMS Backup and Restore, I know, but hadn't run it recently)
Custom Ringtones (Not sure how to do this other than manually)
Application Data (since some apps do store the data locally)
Is there anything proactive I can do or any magical non-root stock supported app to back up this phone 'just in case'?
Thanks.

Well you can unlock it yourself. To do nandroid backup you need custom recovery. To get custom recovery you need unlocked bootloader.

Helium, by ClockWorkMod, will do what you want, I think, and doesn't require root (although it will use it if available). It's in the Google Play Store. I'm not sure what the down side of rooting is, though.

Hi.
Had the same problem as you until i unlocked, i did a full backup using this method.
http://omegavesko.github.io/SimpleADBBackup/
With this method you don't have to unlock or root for just making a backup, i am restoring my backup from before unlocking and rooting as i write this so i hope it did its job.
The backupfile was 8 gb so it must have produced something
I will give you a report as soon as it have restored everything.
Best regards
Mackis

Ok, so the backup was rolling during the night, but i can warn others that my method described above did not work. Maybe i did something wrong but no pictures, no music and no apps did get restored after the backup.
The positive is that im now unlocked, rooted and installed twrp now checking for wich kernel and image to use, i have to read up a bit before next step.

Is it worth rooting the OnePlus 7?

Hi All.
I've got a OP 7 Pro which for the most part, am loving it, except the camera (Messing with GCam ports atm).
I usually root my handsets for the usual de-bloat / custom rom reasons. The last OnePlus I had, I rooted and installed TWRP. Didn't have much success with custom roms so ended up running pretty much stock (but could no longer update OTA for some reason). Since OP don't put loads of bloatware on, I din't mind so much, although I do like to mess around. I really want to be able to do full nand backup which requires unlocked bootloader = all data gone. I can handle reinstalling apps etc but loosing Google Authenticator is a pain in he ass. Do you guys think it is worth rooting at all? Is there a full backup technique that doesn't rquire unlocking bootloader / loosing current data?
I'm not particualrtly hopeful but any suggestions would be appreciaed.
Thanks.

Root is a good way to start the new year on XDA! ??

Love root!!!

Short answer, yes

I have lived fine without rooting for years.
Have not bricked my device once since I stopped rooting, but why ask here ? People come here just to root devices, try ROMs, Kernels, Mods ....... This place is biased and they will tell you rooting in great everytime

I read the thread you linked to. Nowhere do I see it discussing:
What all will be LOST by rooting besides Netflix 720P. (ie google pay etc and yes I know magisk has a "hide" feature but it fails on several common apps)
How the root can be accomplished without losing data or with a method to restore data lost from bootloader unlock.
Both questions were asked by the op in the original post.

Would like to know this too. I haven't rooted a device for many years, because I need the use of banking apps and Google Pay is my main (sometimes only) method of payment.
How reliable is custom kernels from hiding root?

I have my OnePlus 7 Pro rooted just following the guides on here and my phone still has functioning Google Pay and full quality Netflix.
Pokemon Go was trickier to get it to not recognize the root, I had to setup Magisk Manager a specific way besides just hiding root from the app but other than that everything works great.

Whoops. Didn't realize this was such a big problem. I assumed it was in full quality as I only tested it, but don't regularly use Netflix on my phone. After digging into the app it says I have Widevine L3 and can use only SD with no HDR.

Just bought a P3A, do I update prior to rooting

I will take delivery of a new Pixel 3a later this week. I will thoroughly read through “How to root the Pixel 3a with or without twrp & take OTA updates once rooted” and “How to Root Your Pixel 3a and Install Magisk (on Pie & Q) with or without TWRP”. But before unlocking bootloader and rooting should I accept all updates first during the initial setup?

Oh, i forgot as i dont use TWRP anymore.
Yes TWRP only works on Android 9.
However you can't install it like in the past time. You can only boot it via fastboot. You need to do this everytime you want to use TWRP. However when i tried it in past times it did not work well afaik, a full backup did not work at all.
So yeah try it with Android 9 first.
But with all the google backups nowadays i dont have the need for a nandroid (twrp backup)...
Especially as you can just reflash the stock image with deleting /data.
Here is the main thread, i think it will be more helpfull than i am https://forum.xda-developers.com/pixel-3a/development/twrp-3-3-1-pixel-3a-t3943413

The very first thing to do is minimal setup so you can enable developer settings and allow bootloader unlocking. That's a sticky setting, so then you can update, factory reset, etc. before actually unlocking the bootloader and rooting. Especially important if you're US/Verizon (don't put your SIM in until bootloader unlocking is enabled).

Thanks. So I read the two rooting threads I referenced above. I have always used TWRP in the past, but seeing it not supported in Android 10, I am considering skipping that. Do you think TWRP will support Android 10 in the future? I am a little nervous making changes without a backup. My plan would be to stick with a rooted stock at first than consider migrating to a custom ROM. Any recommendations are appreciated. Phone will be delivered tomorrow.

No , I think most people use a TWRP backup because it restores you to a specifiic point with all your apps, user settings and your data in those apps.
Thats why i used it in the past times. Setiing up a phone in the past could be really time consuming and frustrating.
But nowadays, if you use the google backup (in Settings > System > Backup) (and the whatsapp one for messages - thtas the only messenger i use, but every other popular messager has a backup feature now) setting up the phone takes maybe 10 mins when i flash the factory image, it even gets my homescreen layout and my wallpaper back, also my settings. Apps which support that also keep their settings.
In the past i allways had a custom rom, because stock rom sucked. But with the Pixel theres no reason for me to use a custom rom anymore.
About root, i rooted my phone since i first used android, ca. 2010. But now I really dont need it anymore, so i just keep things stock.

I dont think TWRP will be supported in the futur on A10. Google locked up /system and some other partitions the TWRP team needs to find new solutions but there id not much hope.
Did you buy your phone unlocked? If yes, the worst part you should be worried about is losing you app data from some apps. You cant really brick your phone. In the worst case you just need to flash a factory image.
You should know that rooting your phone will probably break google pay and banking apps. May i ask what did you want use root for?
I dunno, I really like Lineage OS, but it just feels like a downgraded stock rom.. (I used it before all the time on all phones before getting a pixel).
Also, for every update (monthly) you need to patch your boot.img, flash it, and the apply the update. Its some work which i dont think is worth it anymore.

Thanks for the detailed reply. I am coming from a MotoG3 (rooted stock), a 2015 era phone. So a lot has changed. I really have not seen a mid range phone I really liked, so I jumped on the P3a when I heard the news they were being discontinued.
I use root mainly for Adfree, SD-Maid, and Titanium Backup. I used to use Cerberus until the developer reneged on a lifetime subscription. I don't mess with the system apps much, but I do keep a few apps frozen except for the times when I seldom need them.

Magisk is the best way to root your phone as it still passes the SafetyNet check and google pay and banking apps continue to work. There is an excellent thread here on how to do it.
[Guide] How to root the Pixel 3a with or without twrp & take OTA updates once rooted
Every month, I "uninstall" magisk (which really just restores the original boot files) and sideload the latest update, then I install the magisk-patched boot.img and my phone is rooted again.
To be honest, I don't miss twrp at all. adb and fastboot are all that's needed. The backup in android 10 is perfectly sufficient.
This phone is practically impossible to brick. I love my Pixel 3a, except for the one problem I had when the bottom speaker died and I had to have it repaired under warranty at the local ubreakifix in less than an hour.

Yeah, I had that phone too It was pretty good for its time. I even replaced the screen once, but its really complicated on that phone... To your needs:
Adfree: you can setup a custom DNS server (i think it was adguards one) in the settings menu which will block all ads, so no real need anymore for adaway or root for this. Just google a bit.
Titanium backup: I does not work so well is what i heard and like said nowadays most apps backup over Google backup. With Android11 it will get even harder as /data partition is even more protected now. Not really worth it imho.
Froze system apps: Pixel Android is really barebones. The few apps which i dont need (like Google Music/Video PixelBuds app etc) you can just disable them in the settings. This will freeze them, its like uninstalling them, they wont show up at all.
SD Maid is great but only rooting it for using it, is not worth it. You can clear the cache of the apps which hoard a lot of data by yourself. Also, when you uninatll an app, it asks you if you want to delete your userdata as well. The phone takes care of the rest.
Cerberus: If you keep your bootloader locked, when your phone gets stolen, nobody can access your phone. Even if they reflash it, on first boot it will ask to login to the gmail last time set up. Theres no workaroud. Google aslo has a find my device thingy, wher you can track or delete your device remotly.
I would suggest to use your phone unrooted for some time, and if you really need to root it for something, you can still do it.
Welcome to team Pixel, mate!
(sorry my grammer im to lazy to double check it...)

@bejunk Just a not to say thanks again. I took your advice and did not root. However, I did flash with GrapheneOS and then re-locked the bootloader. Time will tell if I like it.

How can i recover my phone photos

I installed new soft to my phone and i lost some of photos, screenshot
If I rooted my phone, can I recover my data that was lost after the software update? Can I unroot it later without any effects or issues with banking apps and financial services?
Also, I hope there is a way to retrieve photos and files without rooting the phone because I have tried several methods on both the phone and PC, but they are not recognizing the device even though it appears on the Explorer.

Short answer:
1. A stable wired / wíreless ADB must be given
2. The partition that holds the data in question must be decrypted
3. The phone must be rooted
4. The partition in question must get dumped to PC
5. An external forensic software is needed to read the dumped partition / fles in question

To root your phone, you'll need to unlock the bootloader first.
If you unlock the bootloader, it will erase your internal storage and all files will be lost.
Is your bootloader unlocked as of now?

To keep you updated:
You are able to root Android without unlocking the bootloader, keyword: temporary root.
Even though it is possible in some cases to obtain root access without an unlocked bootloader, unlocking the bootloader is required to permanently root a device.

What are the uses of temporary root?
This post says it is not possible in Android 6 and newer.

I know that people around here who claim a temporary ROOT isn't possible at newer Android versions. That this still happens / happened here at XDA doesn't make things true.

I'm interested to know if it can be used to debloat the system without tripping Knox or other disadvantages of an unlocked bootloader.

Activating that option is just the first step. There are other things to do to unlock the bootloader.
Since your bootloader is locked as I expected, rooting to recover files is out of question now. That's because if you follow steps to unlock the bootloader, it will wipe everything on your phone. The question of recovery won't arise.

To keep you updated:
You are able to root Android without unlocking the bootloader, keyword: temporary root.
Even though it is possible in some cases to obtain root access without an unlocked bootloader, unlocking the bootloader is required to permanently root a device.

If you root the phone, will this cause a problem with banking financial applications?
is it possible to completely remove the root after that without any problem or I will need to make a new software?

As I can see you've no idea what rooting Android means: it's simply spoken adding SU binary to Android's
filesystem - preferredly put it into RW-mounted /data/local/tmp directory. My recommendation: Become familiar with this, e.g. look inside here.

I know that people around here who claim a temporary ROOT isn't possible at newer Android versions. That this still happens / happened here at XDA doesn't make things true.

So why not just teach us ignorant noobs and grab the cash?
I didn't even exclude exploits (such as mtk-su) in my bounty, I just limited to a real android device phone or tablet

@shadyhoo if you factory resetted the device during update, your data is already lost.
You can root your phone after bootloader is unlocked. There might be a way to cheat bootloader and root with Magisk, but still the chances to recover any data is very low to zero. On flash memory the data is discarded right on deletion, recovery tools on file system level won't work because only the emmc flash memory controller (which runs it's own proprietary firmware) knows where the data is located. Only data that isn't discarded yet might be recoverable if it's not too long ago deleted.
It would be possible to get a dump of /dev/block/dm-0 and run extundelete if custom recovery were previously installed. Unfortunately the TWRP for Sony Xperia xz1 compact AFAIR requires custom kernel that supports FOTAKernel partition, boot image must include ramdisk extraction utility extract_elf_ramdisk for installing custom recovery. So this is a showstopper even on cheated bootloader lock.
you can however try to flash magisk patched boot image in EDL mode and see if that passes locked bootloader anyway, if the boot.img is properly AVB signed. if phone is rooted you can dump /dev/block/dm-0 during runtime.
But first clarify how the data was deleted. If a factory reset during the update occured it's absolutely pointless, because once the disk encryption key has changed the data is 100 % unrecoverable.

That's what happened to me an error occurred and the phone froze and then rebooted continuously, it never works, I tried to turn it on for a whole day uselessly bootloop continuously ,
I connected the phone. With a pc using sony companion pc program to repair software, app tell me will erase every thing while installing a new software and erased everything, and the phone appeared as a completely new object
through Google backup downloaded applications, messages, etc.,
but personal photos and files do not exist, and this is what I'm looking for
Do I have any chance to get my photos back or is there no chance ?

This counts as factory reset, therefore no chance sorry.

I'm sad to see so many people get into this position.
Backing up the data to MyMegaApp can be complicated because some of that is stored in /data/data/com.mymegaapp/...
Some of that is stored in /sdcard/Android/data/com.mymegaapp/...
Photos are generally stored in /sdcard/DCIM/Camera and that is trivial to backup.
Photos are probably the most valuable thing you have on your phone.
For Windows user, you can use my adbsync.exe in my sig.
Here is one line out of my "sync" script (actually a makefile):
Code:
adbsync /hscu /s C:\Handy\MotoG storage/emulated/0/DCIM/Camera
So at the same time I make sure that all my books and guitar transcriptions are on my device I also backup all the photos.
This probably happens multiple times a week.
And of course I backup my desktop too.

This. Or just do not care attitude. I still had that when the 1st mSD died. 2nd was bad, about half year of photos and such went. Still hoping to recover it somehow. Then 3rd one went not so long ago. Windows "fixed" it, but now it has some folder added, with files that I don't what they all are... less than a month of damage this time...
So, like Renate said, take backups and take them often.
Adbsync is really good indeed.
Although the usage instructions might need some more details/examples like above...
(Just like some of Renate's other progs - might... )
edit a typo

Mmm, probably guilty. You can always ask though.
I always say that I wouldn't cry if a truck ran over my Android.
That is, as long as at the time the device wasn't in my pocket.

That's not how it works... people just don't realize the potential of your programs that way..
Probably i'm not any better in that though.. lol.

Yeah, I probably should add some examples to some things.
Edit: I added some examples and stuff. Happy(er)?

I was looking in the previous days to recover data from the phone and found a lot of programs, most of which require root for mobile and are not free, meaning that if I want to restore some files, I have to root and also format the phone!! And you all say that it is almost impossible to return files after formatting, so what do all these programs that require rooting the phone do?! I do not understand the usefulness of such programs
