No acccess to system partition? - OnePlus 7T Pro 5G McLaren Questions & Answers

TWRP and other tools cannot mount the system partition like other phones such as Samsung. Is this also the case with pixel and similar phones, or only with OnePlus devices. If the latter, why the h..l did they set it up this way - especially since they allow unlocking bootloaders ?

This is an issue with devices that come with Android 10, not just OnePlus.

Because you're expected to use Magisk instead, which is systemless and does pretty much everything you'd ever modify system for.
Chances are whatever you want to do already has a Magisk module equivalent.

No - want to do a complete ROM backup, and the ability to restore it all or by partitions.

And you can. Everything non-critical is in the super partition. I think system can be backed up individually if you cared enough.
Any backing up and restoring should be done using MSMDownloadTool, that EDL backup tool, or a properly thought out dd.

Backing up without root

My buddy and I are about to start experementing with custom roms on his Droid X. He accepted the update, and I read how to aquire root using a specific sbf [I have it written down] but I don't want to start till we have a backup of his aps. With Cwm or titanium I don't know how to do this.
Can someone give some advice?
Well, if you have cwm, then you can use the "Nandroid" function to make a complete backup of everything on your device (though there may be some exceptions, you should read up on those). If you are rooted right now, then Titanium Backup would backup all your apps+appdata to a specified location (again, read up on exceptions to those).
I would recommend doing both, just to be extra careful, in case something goes really wrong. And again, do as much research as you can.
Edit: If you have none of those, you should use apps like ASTRO, to back up your apps, though the appdata may or may not be backed up with it.
Hope that helps.

I know how to do nandroid backups and I'm very familiar with titanium backup on OTHER devices. Both of those require root. [last I checked]
My understanding is that to root the droid x meaning using fastboot files, which as I understand, will erase your device.

Unfortunately, rooting the device will wipe everything, as you have to flash a whole other rootable firmware.
Search the market for a non root backup app. Any one will do, I recommend trying MyBackup.

How to restore form Google Backup after rooting?

Nexus 7, rooted, back to OEM/Stock~~factory, prior to rooting, read all available documentation regarding backups, said everything was on Google "cloud".....now that I am OEM w/root, how do I get back everything I setup installed and configured for the last week?

If I understand the process correctly - it saves settings regarding Google services. That is apps such as Currents, Play Store, Google Now, etc. It shouldn't backup things such as random app data (IE Angry Birds) - you'll need to use a third party app such as Titanium Backup or App2Zip. For a full system image of apps/settings you'll have to do a nandroid backup through a recovery program (IE ClockworkMod).
Hope that cleared things up a bit. You're gonna be SOL for most of your stuff for this time, but for next time just make sure to double and triple check everything because backups make the going-to-stock process so much nice
Mine did it as soon as I signed into my account on setup.
Some apps had to be installed again from My apps at Google play but the data also was there after they installed. I had some list and such from a notepad app and they were replaced with the app.
So then, the preferred application-procedure is?

So then, to be clear, to have a similar procedure, like iPad/iPhone syncing, there is nothing "built in", and 3rd party applications need to be purchased or obtained free.......so what is the clear winner (easiest, best, most preferred)?
So which process?

Maybe not clear. I already did my N7 and was lost. Wife has hers all tweaked, wants me to root. I just want to restore exactly like an iPad so nothing is lost. Preferred method being search foe. Would like advice.

Google Play can redownload the apps you previously got from them. It will also sync certain (but probably not all) settings, wifi passwords, etc. However, the process of downloading takes around 30-60m and usually app data is not part of this sync.
This, I prefer to use titanium backup to backup all user apps and data (as a rule of thumb, you generally don't want to do the same for system apps/data). The backup is stored on your sd card (so, for example, after wiping data you can restore all your apps within around 15m, asynchronously) and you can also have it backed up to the cloud. Tit backup requires root and the pro version costs around $7.
You can use it to backup system data (your settings and all that) but this is a bad idea when you use custom roms. I usually restore my apps and set the rest manually, the whole process takes around 20m.
I don't know how well itunes backs up app data, so I can't answer the comparison question.
Unlocking is what wipes the data, not rooting. You are already past the point of no return as the restore info you get back from google does not deal with a lot of app data. You could have before unlocking, done a process which would have saved it, but it is not a normal process and certainly not automatic.
you are past that however already.
Now you are rooted, you can use Titanium Backup to do a real backup and you can also do a nandroid backup using Recovery so you don't have to deal with this in the future.
HOWEVER, just doing those backups doesn't guarrantee you can access them if your device is lost/stolen or damage beyond repair. So you need to come up with a method to copy those backup files occasionally to workstation off from time to time so, you have something to restore.
Then if you have to setup a new device, you can unlock, root, load TB, copy the backup files to the device and then restore the system back to where it was when you did the last backup.

You need root (and an app like Titanium Backup) to back up your app data, and you need to have an unlocked bootloader to root. If you didn't already unlock the bootloader on the Nexus 7, then there's nothing you can do to back up all your app data because unlocking the bootloader essentially resets the device. Without a backup program, the most you can do is sync your device with Google Play and have it reinstall your missing apps after you wipe your device (but it won't restore your app data).
But......

But I did "root", and I did lose all my data, like it was OEM out of the box, but rooted....
Unlocking? Why would I 'unlock'? If I only want to use USB memory stick isn't rooting all I want?
Therefore, I'd get which program to root only to preserve everything.
The confusing part is "You need root (and an app like Titanium Backup) to back up your app data"
How can I have Titanium if I don't root, and if I root, I lose everything?
(or did I maybe also unlock mine..... I'm really confused, all I want is a 1-2-3 root app to install the Stick Mount. Period)
Thanks again for the replies, I'm hopefully getting this Android stuff

You need to unlock in order to root (though you can relock it after if you want, I wouldn't recommend it in case you need to do so again) and flash stuff.
If you didn't relock it from earlier (i.e. if you still have that "unlocked" symbol on boot), you'll be able to root again just by flashing the superuser program.

Wug's root toolkit has a backup/restore option.
In general, however, the answer is yes. You are not able to (at least without expertise) backup data from prior to your first unlock. That's why it's recommended to unlock your device asap if you decide to do so.
(The OEMs wipe everything upon unlock for security reasons - the only way to get around this is to use an exploit rather than the "fastboot oem unlock" command, but the discovery of such exploits is unpredictable.)
OK, here I go

Thanks for the attention to detail, I appreciate it.
I just install cm10 and I noticed that the settings such as wifi passwords etc have not been restored. Any ideas on how to restore them? I'd post on their thread but they don't have one for the N7 and I still don't have the privileges.

N9 Nandroid Backup

I'm looking for a replacement for the Online Nandroid Backup app... an app which allows the user to create a nandroid without having to boot recovery to run a backup. The app's author appears to have abandoned it, and a "Onandroid" script is required for the program to work properly with new devices. There is no script yet for the N9 or N6, so the backups complete normally, but will not restore. I've tried selecting the script for similar devices and have not had a successful restore yet on either the N9 or N6. I don't know anything about Onandroid scripts, and have reached out to the dev, @ameer1234567890, but have not heard anything back. I've also provided feedback from within the app for both devices. In the best case, maybe someone help me with editing an existing Onandroid script, else I'm looking for another app with the same functionality. Here is a link to the dev's thread:

Yes, I can continue to use TWRP, but for me backing up online is faster and more efficient... running the backup in the background while using the phone/tablet at the same time. The combination of Online Nandroid Backup (ONB) and Nandroid Manager was excellent. Still use it on the N7/N5. Just looking to get some script help so I can use on the N9/N6 (or similar alternative app). Thanks.

Nexus Imprint doesn't work after TWRP restore

I have a 64GB Nexus 6P and am upgrading to 128GB. I backed up and restored via TWRP. I removed security before the backup. However, when I restore, I can't add a Nexus Imprint - it keeps saying enrollment was unsuccessful before it even lets me try to read my fingerprint. However, if I do a clean wipe & install, the fingerprint reader works fine.
Any suggestions?
seems to me something i borked in your backup. probably just going to have to start fresh. unless... of course... your backup contains a probram or xposed module that could be causing the problem. then it would just be a process of elimination to determine which one.

I've tried it twice (full cycle, backup, wipe, restore) with the same issue. I haven't installed Xposed yet.
I don't think this can be a program issue, I think Google added something at the OS level.
I hate starting fresh. Even with Titanium Backup, it takes forever.
That happened to me as well. Only way that worked was a complete clean flash for me.

I don't know if it's just my experience, but TiBu takes for-EVAR to restore APKs (not data, thats fast). Just forget it for any sizable app like Chrome or Facebook. So, I started using another app called AppWererabbit strictly for purposes of backing up/restoring APKs. With root privileges, it'll batch install over 100 apps fast. Then for a subset of apps that are non-trivial to set back up, i'll use TiBu to restore the data. Unfortunately AppWererabbit seems broken on Marshmallow for me. Also, Pro key is needed to do anything worthwhile.
I've looked into using TiBu's feature for creating flashable zip's to skip all that but it has yet to work for me a single time. I have, however, had promising results with some modest testing of this app called ZipMe that is in beta (also, tested on a Nook HD+ not Nexus6P)
Also, am I to understand you are trying to restore a nandroid for one device onto another?

Thanks for the app recommendations. I tried ZipMe, it didn't work. Or at least I couldn't tell that it worked... It processed for hours but there wasn't an output zip.
Yeah, not impressed with Titanium Backup right now, either. Pretty frustrating experience overall.

It's a bug with TWRP and the 6p, after restore in TWRP, use the TWRP file manager navigate to /data/system and delete locksettings.db file. Reboot and the secured lockscreen will be gone, just set up a pattern lock again and the secured lockscreen will work as normal with your saved fingerprints.

For this problem deleting locksettings.db is not working. This is different problem than you talked about.
It's been discovered in other threads that there is a hardware key associated with the fingerprint scanner. Which means you can't restore a TWRP data backup from one device to another. That sucks bc this is my main motivation for keep a TWRP backup. Hopefully, a solution will be found.

I don't know about transferring devices but restoring a backup and then using the twrp built in file manager to delete locksettings.db is what I do with my backups. And it works every time.
Right, that works for restoring TWRP backup to same device. But if you get another 6p for any reason, and then restore this same backup to it, the fingerprint scanner will not work.

How do I go about creating a full backup image if I'm unrooted?

Normally I'd use TWRP to create a full backup image but since I'm unrooted I'm not sure how to get this done.

Hi, if you have a Samsung and you don't have root, I don't recommend backing up via ADB because Google doesn't support this anymore, it's more recommended to use Google One or on a Samsung you can use this guide which should also help you.
Don't use SmartSwitch.
First redundantly back up all critical data to at least 2 hdds that are physically and electronically isolated from each other and the PC.
Hand load everything; copy/paste, verify size and if readable. Any apps like Poweramp or ColorNote that allow for backup import/export do so. Organize your critical data; have a plan.
If you have a SD card it is your data drive; all critical data goes here including installable copies of all your apps. A full restore should be able to be done with the data on the SD card.
A clean load can last for years if you don't muck with the firmware ie upgrades/updates. Think it through and do it right the first time. If you do it right it won't need to be done again for years... that's what Android is capable of.
you can't create a full backup as you can't access the needed devices... the only thing you can backup is your sdcard,data and probably efs with system shell exploit
