Any recommendations for non root android recovery

BloodBlade · Mar 26, 2019

Hi

I changed my lock screen password and I forgot it. Now it says unable to use fingerprints enter password. My phone is a boost mobile lg stylo 3. I called my local boost mobile store and they said to call boost mobile customer service and boost mobile said to call google so they could help with getting in thru my google account. I tried their number menu and I eventually was disconnected. Is there a good data recovery for android that doesn’t require root that I can use after factory reset? I ask cause I don’t think I have a google account that has my android data backup. If it’s recommended and doesn’t require root I’d be willing to pay for the full version. Can anyone please help. Thanks in advance.

I don't think anyone can. The internal storage is AES256 encrypted, and if the phone is factory reset, the decryption key is erased, and any data is just white noise and unrecoverable, unless you got a supercomputer and 100,000 years to spare

There's no backdoors in, because that would defeat the purpose of putting a password on it in the first place.

But isn’t there a way to recover data through google’s apps after factory reset?

Only if there's any data on Google's servers, in the cloud. But you said you didn't have a Google account that was linked to this phone?

Trying data recovery software on the phone itself after a factory reset and the decryption key erased, will not work. That's one of the premises of having securely encrypted storage. Any recovery software will just see digital white noise.

I wasn’t sure if I did and I don’t know how to find out to be sure.

I see all these data recovery apps for android but require root. Some claim u don’t need root. I looked and I don’t think my lg stylo 3 supports root.

Oh ok. That’s unfortunate. Well can u tell me what to do to use google for recovery? Or a link. I checked and I do have a google account according to my password manager. I’m not positive it’s linked to my cell

Let's hope it was your registration account because otherwise you're out of luck. First thing you want to do is log into your Google account from a PC. Since you have it in your password manager, I would assume you can login without resetting the password. If you can help it, don't reset the password because that creates additional problems when trying to access your phone.

Once logged in you will want to check gmail, contacts and photos. If they are there, then you can restore them if you reset your phone. You will lose your text messages, unless you specifically backed them up off the phone.

Once you've got access to your Google account, you can check to see if there are any device backups at https://drive.google.com/drive/backups. If so, they'll be available to restore your apps and data when you set up the phone again.

I wouldn't waste any time on any Android recovery software. They're ineffective (at best) and outright scams (at worst - and, if I'm honest, that's the case for most of them). Like @mikedt said, all of the data on the phone is encrypted specifically to avoid an unauthorized user from gaining access to your personal data - and at this point, you are that unauthorized user.

Whether you're phone was rooted or not rooted is irrelevant when it comes to trying to bypass its lock screen. Even if it was rooted, that wouldn't allow you to bypass the lock screen anyway.
But the bottom line is if you're not even sure that your own Google account is what is used as the authenticating Google account on this phone, who does this phone belong to? If you log into your Google account on computer, is this phone listed in your device manager?

Hey guys. Thanks for the help so far. The LG stylo 3 is my phone and that’s what turned up at that link. I was able to turn off 2step verification so I was able to get into my gmail accounts on my computer. I did a google back up of photos contacts and so far on the google + or drive. Anyway now that I have that backed up am I ready to do that factory reset? Or is there anything else I should do?

You can backup app data on Google drive, as well as having apps re-installed upon recovery. [This is based on the idea of doing these things before disaster.] I also recommend running a regular backup (at least every other day) on your SD card. I run a (overwriting) backup to my SD card regularly and send copy to my gdrive when done. It has saved once when facing the issue you're dealing with.

While TWRP is not available for the LG Stylo 3 (because of the bootloader being unsupported for unlocking), root can certainly be attained on the LS777 (Boost, Virgin, Sprint) model, but not systemless root as you would expect on a device running Android Nougat. Again, due to the locked bootloader, Magisk systemless root isn't an option. In order to root the LS777, you must use LG-UP for store Dev Edition to dump your /system partition. Once dumped, change the file extension to .img to convert to a system.img file. Next, an Android kitchen can be used to decompile the system image and inject root binaries to /system/xbin/su (I used dsiXDA's Android kitchen which utilizes SuperSU 2.82-SR5 to inject root system-wide.) Once root is in place, the system directory is recompiled into system.img format. Now return to LG-UP Dev Edition and use the "DL" option to flash the patched system image to the LS777 /system partition. (NOTE: DO NOT attempt to root with systemless Magisk or otherwise attempt to modify the boot image in any way. Android Verified Boot (AVB ,1.0) along with LG's notorious secure bootchain feature will result in a boot loop with a "SECURE BOOT" error message during the boot process.) Once the rooted system image has been flashed with LG-UP, boot the device into the Android OS. Open the SuperSU root management app and follow any prompts to update the root binaries (using the "Normal" option.) You are now fully rooted with /system mounted R/W.
Here is a link to my stock firmware thread over at XDA for the LS777 model. I used LG-UP Dev Edition to make a complete and unmodified dump of all device partitions in .img format. I archived the images and uploaded the .zip to cloud storage to host it: https://forum.xda-developers.com/t/...77-boost-mobile-sprint-virgin-mobile.3958553/ The system.img from this firmware archive can be used to inject root. It is very likely that this system image root injection method will work to root other variants of the LG Stylo 3 as well, but this is pure conjecture. The only model I can confirm is the LS777 Sprint compatible CDMA/LTE variant, using the firmware build that I linked above.
