Nexus 4 rooting without data wiping - Android Q&A, Help & Troubleshooting

Hello all, I am a new subscriber, so I don't know if I am writing in the right place.
I have an LGE Nexus 4 device installing Android 5.1.1, build LMY48T.
I need access the files in the internal system memory of my phone, in order to try to find and restore some records deleted from an SQLite database (they are a bunch of Google Keep notes that have been accidentally erased). To do so, I must necessarily root my phone.
Is somebody capable to suggest me a rooting way of my phone, obviously without wiping my data? I am just interested in rooting my phone and keeping my data, nothing else.
Thanks in advance for any eventual help.

Possible to recover deleted files after unlocking bootloader / rooting?

I stupidly trusted the "transfer to SD card" function and now my Z5 Compact has moved a big chunk of my photos from internal storage to… nowhere. They've been deleted and I'm not sure if I can get them back. I've managed to recover the thumbnails using FonePaw so I'm assuming the original full resolution files are still hanging around somewhere in the internal storage.
All the "recovery" tools I've found require your phone to be rooted in order to recover the deleted files from the internal storage. I'm aware that, in order to root the phone, the bootloader needs to be unlocked but that there are issues with losing DRM keys and the impact of that on some of the phone’s functions (specifically a number of the camera features). Given the camera was the primary reason I purchased this phone, I am reluctant to do something that messes with that, especially since this is the second handset as the first one was replaced under warranty after only three months (and this one still has 4 months of warranty left and has been having intermittent issues). There is also the issue that unlocking the bootloader factory resets the phone and therefore wipes all the data.
I know there is a bit of a workaround in that I can downgrade the firmware from Marshmallow to Lollipop and temporarily root the phone in order to backup the TA partition so I can restore the DRM keys et al after unlocking the bootloader and rooting the phone. Again, as I understand it the firmware downgrade will wipe my phone.
Normally wiping my phone wouldn’t bother me beyond being a pain to reinstall apps etc. What concerns me is that, given my missing files are likely floating somewhere in the internal storage ether, would a factory reset completely wipe those files from the phone permanently? Or would I likely still be able to recover them using appropriate software even after the reset, downgrade, unlocking of bootloader, and rooting?
I don't know much about it (and I’m willing to find out more for myself) but Is it possible to use something like adb backup to back up the whole phone and restore that to the phone after rooting in order to recover the missing files? Or will that also only work on a rooted phone?
If it's unlikely that my missing files would survive the repeated resets during the rooting process then I will probably just take this as a lesson learned the hard way and not bother trying to recover the files. Given the way my luck has been going, this handset will also fail before 12 months and I’ll have no warranty – and still no files!
Thank you in advance for any light you can help shed on this dilemma

Data recovery

A family friend has given me his Xperia Z5C (running 7.1.1.) as he's accidentally deleted some photos and wanted me to take a look at recovery.
We all know that to get the necessary access the device needs to be rooted, but this also requires wiping the device. My question then is how secure is the wipe / erase when rooting, is it a full overwrite (in which case there's little point trying) or is there a chance that some data might be present at the block level after rooting?
I'm not inclined to go through the process of rooting if it's futile, but if there's a chance there may be some files still recoverable, he'd probably want me to try.
Thanks for your help.

Can we restore/extract Photos/Datas from Fully Formatted OP3T Unrooted Phone ?

Hello there,
I recently lost my mobile and when i found the phone the next day , the person who took it had already fully formatted it.My phone is One Plus 3T and it was unrooted before.I tried many ways and apps but all says I need to root my phone now to get the photos n datas back.Could you please suggest me any ways to get my datas without rooting.And shall i get all my datas 100% back if i root it now though?Since i have found my mobile ,i haven't use its storage so that its previous data print don't get overlap.Please suggest me effective way to get my photos n datas back without rooting if possible or if not than by rooting process.And if rooting is a must than suggest me a link of rooting OP3T,i am new to it.
Thanks.
You can try different software but you will not be able to get everything back. The best you will be able to hope for is maybe 25% of the photos but that is all you will get back.
could you please suggest me different softwares for recovery of photos without rooting?..
Without knowing the pocess used to format the device, and any subsequent use, it would be impossible to tell how much of your data still resides on your device. Any guess made on this would be frivolous. If the data is extremly important, forensic techniques could be applied to retrieve the data. This would require proffesional forensic software such as XRY to aquire an image, and analyse it. This software is extremly expensive, and not designed for end users, but is deployed by some data recovery firms.
It boils down to the depths of your pockets, and the importance of the data lost.

Recovering deleted media on my Mate 10 Lite

Hey there, its my first post over here as it's obvious, i know my question might fit better under the dev section but it wont let me create a thread there, so bare with me.
Anyway, the problem is that i accidently deleted some media files from my Huawei Mate 10 lite (Images & Videos) and since then i spent like over a week googling trying to find a way to recover them without a clue. All the android data recovery apps require Root access to be able to do its magic, then again as i heard it's not possible to root Huawei phones on Android 8 with the latest security patches since its not possible to unlock the bootloader in order to install a custom one to flash whatever is needed to root the device, so that's a dead end at least to my knowledge.
The question is, Is there any way at all to recover those deleted files without the need to root the device ? if root is required, is there any safe way to accomplish this nowadays ?
Thanks in advance,

Unfortunately, there's no way to recover deleted media files . I had the same problem on rooted phone. I have tried several programs without success.
(If you store some new data in your memory then there is a big chance that the data get stored over the deleted data. So no chance of recovery after overwriting a humongous amount of data.)

Without root? Probably not.

Android OS doesn't have a Recycle Bin as that's the case with for example Windows OS, unless you install such an extension.

That is true, but, deleted data doesn't truly get wiped/removed unless the data is overwritten. When a file is deleted, it doesn't get deleted, it just gets marked by the system to be ignored until the next time the system needs to write data, at such times, it will write the new data over the data that has been marked.
Data recovery software does have the ability to find this data that has been marked for deletion and recover that data. But it requires root.

Most of the recently released higher-end Android devices running Android Lollipop or higher come with data encryption enabled out-of-the-box - in order to be more resistant to government snooping.
IMO even if it may be true that a data recovery software can find and recover deleted data, these data are encrypted and therefore without any use of all, unless you have appropriate forensic tools.
If I'm mistaken then please tell me the data recovery software that can bring back deleted data in decrypted way.
Data recovery software works for you, but all require the phone to be rooted, so you will need to do that first to your device. With root access, it can scan the files that would normally be inaccessible.
It can be recovered back with some data recovery software?If the.zip is too large,i tink it will be difficult to recover back.

I Do not mind rooting now, but !! my understanding is that if I root the device now., It will wipe off all my data in my phone, coz rooting the phone is another way of flashing?? It will be more hard to recover file if my phone is wiped out.

My file is hardly 150MB zip file. Not of huge size.

Yes, but, only if the rooting method requires unlocking your bootloader because unlocking the bootloader formats the data partition. But, if you can find a way of rooting without having to unlock the bootloader or flashing a custom recovery, it won't format your data partition.
Honestly though, your chances of rooting without unlocking bootloader or flashing custom recovery , aren't very good. To do so would require finding an app or PC program that is a "universal rooting tool" and it would require the tool having an exploit that works on your device.
Or, you could do a Google search for:
"Recover data android no root"
Then try the various tools and methods that finds, if you can find videos in that search, it may help you further.
