Replacement phone via Uh-Oh, Can I use NANDROID backup?

I managed to somehow break my 3 week old HTC 10's rear camera glass so I'm going to get it replaced via the "Uh-Oh Protection" since I bought from HTC directly.
I have the Unlocked US edition, but use it on Verizon. When I get my replacement phone, I'll go through the steps to Unlock via HTC dev, run Sunshine for S-OFF and change the CID/MID to Verizon. At that point, can I just flash a NANDROID backup from my old device onto the new one to get my ROM / Apps / etc. back? Will there be any issues since it'll be different hardware? The NANDROID will contain everything I need so I won't need to first apply the VZW RUU right? I think I've done it before on previous HTC hardware but I want to check if it'll work before I try it. Will encryption be an issue?

Sounds good as long as correct firmware is also flashed

I don't see it being any issue.

So I just got my replacement phone. I followed the exact same steps as I did on my original HTC 10 to get s-off and convert to Verizon (used the same files as well). I made a fresh NANADROID backup on the old phone in TWRP, copied it over to the new phone, and restored it. When I reboot I get stuck on the white splash screen. I tried wiping the cache but I can't progress further.
I was really hoping I'd just be able to use the NANDROID so I don't have to go through the arduous process of backing up all of my apps and settings, and copying them over in TiBu, and having to recustomize everything in VenomHub/Xposed.
What am I doing wrong?

Try dirty flashing ROM

How would changing devices between TWRP backup/restore affect encryption?
EDIT: Since TWRP decrypts now, phone encryption would be a moot point in this context.

I received a replacement Uh-Oh phone from HTC. Unlocked bootloader, installed TWRP and S-Offed. Tried using my Nandroid to restore but TWRP would not see it (file names different, based on S/N). I created a small new backup to create the proper file structure and renamed the old Nandroid backup and placed it in the proper directory. Still would not work so I went to my TiBu backup and reset everything back up.
Here's a strange result though - my fingerprint works fine to unlock the phone but somewhere along the line (perhaps my attempt restoring Nandroid) the pattern lock changed. So now I cannot unlock phone using the pattern and cannot change it. I can use fingerprint so it works for now but I would like to reset the pattern lock - any ideas?

So when you did a restore with TWRP, what was the result? What does "still would not work" mean exactly? What did the log say?

I'll have to dig into the log file but it is my habit to only backup /data. That's what I was trying to restore. I might need to factory reset to get the pin reset I suppose. Was hoping there was a file I could delete to reset the encryption.

Just in case anyone has this issue of losing their pattern lock from a Nandroid restore I found the answer in a different thread. Use a file manager with root access such as Root Explorer, or use TWRP's file manager capability to delete the locksettings.* files in /data/system. Reboot and your device will no longer have a pattern lock. You will need to create a new pattern lock along with new fingerprint unlocks.

Factory reset erases everything, leaving nothing to decrypt.
Your idea of "reset encryption" would make encryption useless if anyone could just remove the lock without the PIN/password.

10. After I restored my Data backup and boot back to Android, I'm entering the correct PIN/password, but it's telling me the password is wrong. What happened, and how do I fix it?
It appears that sometimes after restoring a backup of Data where security was enabled (such as a PIN or password lock), the device does not recognize the correct password. There are two ways to avoid this issue:
Disable security in Android?*before?*making a backup of data.
After restoring Data, while still in TWRP, use the TWRP File Manager to navigate to /data/system and delete all the locksettings.* files (such as locksettings.db, etc). When you reboot, the password will be gone.

Is that referring to unlocking the screen or decrypting the device?
The question was referring to encryption.
When TWRP restores a backup, is it encrypted? (There's a few "it depends" to that question I would think.)

From CM13 back to Viper

Hi guys, first, sry for my bad english.
I have a huge Problem. I did a Twrp Backup from my Viper rom. After Backing up, i installed cm13. After that, i would go back to my backup from Viper. The Problem is, i can restore the Backup but ive got a bootloop. How can i go back to my Backup ?
Next Problem is, everytime i start into twrp i got asked for the Decrypt password. How can i deactivate that ?

Which TWRP version are you currently on? Sounds asbif it is an older one. If so, try the latest 3.0.2-6 and report back.

hi, im on 3.0.2-6.
Now i restored my Viper backup. It Boots normaly.
Then i have type my Pin, that works. But after that, i have to unlock the Pattern lock. But it says my Code is Wrong.
I know it is the right code. I can try 1000000 different times, i cant unlock

adb into the phone via TWRP or live system and rm -rf /system/data/*.key and locksettings* this will reset the security. no one currently knows why twrp is doing this but it seems to only happen to me when flashing a different rom then going back. it does NOT does this if restoring a previous backup of my current rom.

really the only file you need to delete is the locksettings.db file. I've never had issues deleting just that one.

I also tried this way to delete the locksetting.db and can bypass the suck lockscreen!
BTW, highly recommend you that in addition to whole system backup in TWRP, also use Titanium Backup to backup all user apps. In case of restore failure, you still can preserve your user apps and restore in newly installed system.

[root] [ZS570KL] Asus Zenfone 3 Deluxe fast rooting method. Despite TWRP

Not tested on nougat.
I use adb and fastboot , twrp, supersu.
Files We need:
TWRP: It's bogus, in my phone the screen flips upsidedown: Connect a mouse thru female usb or try to figure out how to tap in a rotated screen with a non rotated touch panel.
TWRP Download -> https://drive.google.com/file/d/0B0XMYw0cbs_cdm5FZW1DQXl4MFU/view
SuperSU file - > https://download.chainfire.eu/1021/SuperSU/SR3-SuperSU-v2.79-SR3-20170114223742.zip?retrieve_file=1
For ADB access thru MAC:
1.- First of all we have to get open USB debug mode to get adb acces to the phone by going to Settings -> About -> Software Information -> Tap 7 times over Build number.
2.- After we get Developer options available we have to put the phone on usb debugging by goig to "Settings-> Developer Options" Activate USB Debugging.
3.- Install android platform-tools on your PC/Linux/MAC , in my case had work on MAC and no devices acces thru ADB on PC :silly: .
platform-tools -> http://www.androidpolice.com/2017/0...ble-without-full-sdk-android-studio-download/
Here you have the 3 options to download ADB and FASTBOOT
4.- Connect your phone to the PC (USB) and copy SuperSu to the root of your phone, a place that its easy too acces, cause TWRP, for the moment flips the screen.
5.- Copy TWRP3.0.XXX.zip to the folder where you have platform-tools installed.
6.- Reboot your phone to bootloader and in Linux could work too:
./adb reboot bootloader [./ is placed cause I don't put platform-tools on the my PATH]
After the boot, then we have to boot on TWRP
./fastboot boot twrp-3.0xxxx.zip (you don't flash anything) If you want to flash TWRP, at your awn risk, ./fastboot flash recovery twrp-3.0xxxx.zip".
Well, now you have to see TRWP on your phone screen.
My recomendation is to play a little bit with the flipped screen if you don't have a female USB to plug a mouse.
7.- Trying to make a complete backup of the phone could be a good practice to move on TWRP with the flipped screen . Tap backup option and make a Backup. Always recomended!
8.- After Backup, you can go to INSTALL SuperSU.zip file. "Install -> look for your SuperSU.zip file "
9.- Go to Playstore and install supersu app.
Now you can test your root, after reboot for example tryin to install some APP that requires root. Fast move:
./adb shell
su root
It has to appear a screen to grant root access to the phone.
10. Done!
Well I think thats my second post at all, hope can help someone to root the phone.
I placed In Questions and Answers cause XDA says want to protect us from SPAM.
Feel free to correct me anything.

You can also substitute Magisk instead of Supersu if you need to use any of the pay apps or have root sensitive apps...

Without the right Twrp, many benefits to rooting are missing such as removing stock rom applications. Seems without being able to boot to a recovery, even Titanium cannot remove apps because it needs to clean the dalvic.. Can't do it without a recovery

You should change your title !!

Very nice guide, Thank you. Could you please provide updated links to both TWRP and SuperSU. I am currently using TWRP 3.1.1-0 and it functions properly after hanging for approximately 45 seconds on boot. This may be due to the fact my phone is encrypted. I initially rooted without installing TWRP (fastboot boot twrp.img) but have since flashed it. Both ways work well. The posted version of SuperSU did result in root but caused me to lose cell service! The phone could "see" the sim card but not use it. Updating to SuperSU 2.82 solved that issue. This was all done on my finally rooted ZenFone 3 Deluxe Special Edition (Z016D)!!!

I unfortunately figured something out the other day. Using TWRP 3.1.1-0 I am able to install zip files, complete wipes, make & restore backups. The issues only arise after you restore your nandroid image. Everything works except for two things.
1. The ability to hear audio during phone calls. The phone is actually able to place calls but you are unable to hear or record any phone audio. Oddly enough I was able to play music and use voice dictation. It was only in-call audio that seemed to be affected.
2. If you have a pin set when you create your nandroid image your pin will no longer work once restored. You will be locked out of your own phone!!
Fortunately both are fairly easily resolved and keep TWRP relatively useful, although a bit bothersome!
To resolve the pin issue it is necessary to use the TWRP file manager or ADB to delete 5 files (listed below) and regain entrance to your phone. Once deleted simply reboot the phone and reset your pin. If you remove your pin before creating a backup this issue is averted completely.
/data/system/gatekeeper.pattern.key
/data/system/gatekeeper.password.key
/data/system/locksettings.db
/data/system/locksettings.db-wal
/data/system/locksettings.db-shm
To re-enable call audio use TWRP (install zip) to reflash the same version firmware from the Asus website over your current install without wiping. This will restore any system apps you may have removed but you should still have root and can easily remove them again. There will be two errors when performing the flash, which is why I believe root is retained but the system image will be reflashed. Reboot and enjoy
I sincerely hope I have not caused anyone any issues! Or that someone else finds this information useful. I have tested everything in this post at least three times. All testing was done on the most recent Android 7 firmware on my ZenFone 3 Deluxe Special Edition (SnapDragon 821/6/256).

The second issue happens in all the phones/twrp.
It's possible to install the firmware from asus website with twrp?? To update i flash the stock recovery, install the firmware, then reflash twrp and supersu. Didn't know that! It updates successfully with twrp??

Thank you Ryder for confirming my suspicion that the pin issue may have been a more common one with TWRP. This is the first phone I actually cared enough about to use a pin. I was thrown for a loop when I first booted my fresh nandroid restore and the pin I know I've been using was incorrect!
As for installing firmware, with the two errors that occurred during I don't know that you would be able to do full scale upgrade to a higher version. To reinstall the system partition however it does seem to work quite well. I tested this part four times. To do so download the correct device/version firmware to the phones storage, click install, and select that file. After it completes I like to wipe both the cache and the dalvik cache before restarting the phone. The audio issue was unfortunately easily reproduced on my phone, but thankfully equally easy to resolve. This worked for me each time without fail.

You said that the two issues occurred when you restored the nandroid backup and to fix one of them by installing the zip firmware from asus website with twrp... I don't understand. I can install zip firmware with twrp or i have to flash the stock recovery and install with it? Errors may occur using the twrp? Sorry

Everything done in my post so far has been in TWRP. Honestly I didn't even back up the recovery image. TWRP seemed to work flawlessly so I bit bullet and flashed it.
On a sidenote I am currently testing the usability of FlahFire on this device. It appears to create a very nice fastboot installable recovery image! I have yet to restore the image however. I will post my findings here once I have thoroughly tested it.

Ok. I'm interested in flashing zip firmware to update. Never tried that. I thought that firmware can be installed only with stock recovery. The stock recovery can be downloaded in an asus forum website

This is the first time I have flashed anything in almost a year. I got to thinking and this is the most success I have had was flashing a stock image with TWRP! I doubt it will perform a full flash. I believe the errors are most likely for the boot and recovery partitions. As a save my butt reflash the system partition it does work. It sounds like it's time to find some TWRP changelogs!

I don't care about stock images... If i can't flash the zip with twrp to update successfully then i reflash the stock recovery and after the update root again with twrp and supersu. By the way, the zip firmare contains factory images? I thought it contains different kind of files

I lack the knowledge to answer that with enough certainty to even call it an answer! This is my foray into the insides of this phone and I don't want to start posting my hunches.
What I do know is you can flash the system partition using TWRP. I have done it several times. Asus's zips run as a script based zip install. You are offered no options during install. When the script runs you will see two errors quickly scroll past.

When I update my rom, i get locked out then data is wiped

on my oneplus 3 - I just updated my rom from a previous build to the latest, and when it finishes and boots up it locked me out of my phone saying wrong pattern and then I rebooted back to recovery and deleted theses files:
password.key
pattern.key
locksettings.db-wal
locksettings.db-shm
locksettings.db
and after booting up it goes to the setup screen and none of my apps are installed and all my settings are gone. Ive had this happen every time i do these steps with any 7.x.x roms
the current rom im using is RR-remix rom
it doesnt really seem to matter what rom i use, it will do this on any updates.
i need answers on how to prevent this from happening again and/or why this happens, thanks.

To me it looks like a perfectly functioning system. It is protecting your apps and data from a possible thief.
Never happened to me on simply updating, but before you flash anything, try removing all security first (fingerprints, PIN, all of it), flash the ROM and set it all up again.

Before you update the rom do a backup in recovery. Select only DATA. After upgrade restore the backup DATA in recovery.
This too might not work do the changes in the rom security, base.
Why buy S8 ?!? I'll buy OnePlus 5.

Mi A2 Lite bricked?

Hi guys,
I'm having trouble with my A2 Lite. Right after unboxing the phone I installed Magisk as described in the guide (https://forum.xda-developers.com/mi-a2-lite/how-to/guide-install-magisk-device-t3825626), which worked like a charm. Today, I wanted to install a OTA security update. After the update was downloaded I got an error and I remembered that I had to "uninstall" Magisk, as described in "step a" of the guide. So I did exactly as described in the guide. After Magisk was "uninstalled" I closed the app and tried again to install the OTA security ("step b") update. Unfortunately I got the same error message again ("Can't install update"). So I thought f*** it - I skipped "step b" and proceeded to "step c" and installed Magisk into an empty slot. After that I hit "reboot" and now my phone's in a bootloop :-/
bootloader is unlocked, oem unlock and debug usb are activated. I'm able to enter fastboot, but no recovery, whatsoever.
Is there any way to fix this?

just letting you guys know that "fastboot set_active b" did the trick. I don't know what the hell went wrong though. I did everything according to the guide, except for trying to update the ota update (and failing) before uninstalling Magisk.
Now, the phone is booting correctly, but I still can't install the ota update. it says "Couldn't update" and "Installation problem". What the heck...

This is probably due to the root as it modified the system partition. Check the thread regarding on how to update without losing root.

Please go see my guide, I just added a troubleshooting section that you should check:
https://forum.xda-developers.com/mi-a2-lite/how-to/guide-install-magisk-proper-support-ota-t3836952
Your feedback could improve it further.
No, flashing boot.img will not erase any data on the phone. But you must remove any PIN, password or screenlock before proceeding, or you could not access your data anymore (because of encryption).

Hi BubuXP
I followed your troubleshooting guide and flashed the boot.img as instructed. Flashing the boot.img didn't do the trick so I continued with flashing the system.img. I checked for the correct build no. of course and for both boot.img and system.img the active slot "b" was chosen. After flashing the system.img I got stuck at a bootloop. I tried to set the active slot to "a", but that didn't help either: Now it wasn't in a bootloop anymore, but it was stuck at the boot animation (horizontal beam) loading forever. After 10 minutes I tried to restart - still the same problem.
What's going on here??
edit:
I flashed daisy_global_images_V9.6.4.0.ODLMIFF_20180724.0000.00_8.1_4afd3431a2 using MiFlash and the "Save user data" option. It was flashed successfully. However, when I start the phone it askes for a password and won't boot up into android if not entered. What the hell...? I deactivated my screenlock pin before I started all this. Is there a default password or what's the problem here?

I checked for the correct build no. of course and for both boot.img and system.img the active slot "b" was chosen. After flashing the system.img I got stuck at a bootloop. I tried to set the active slot to "a", but that didn't help either: Now it wasn't in a bootloop anymore, but it was stuck at the boot animation (horizontal beam) loading forever. After 10 minutes I tried to restart - still the same problem.
What's going on here??
edit:
I flashed daisy_global_images_V9.6.4.0.ODLMIFF_20180724.0000.00_8.1_4afd3431a2 using MiFlash and the "Save user data" option. It was flashed successfully. However, when I start the phone it askes for a password and won't boot up into android if not entered. What the hell...? I deactivated my screenlock pin before I started all this. Is there a default password or what's the problem here?
regards

Sorry, but I don't know anything about that. It's an encryption problem, and that's why I hate data encryption on the phone: my data is not so important to be protected when some hackers physically stole my phone, it's only a nuisance when things like this happens.
I can only suggest to change the active slot, maybe with this you can resolve.
I will also update my troubleshooting section of the rooting guide to make the data backup as the first option to be safe.
If you can sacrifice the data, you can simply format the data partition via fastboot or reflash using the flash_all.bat script.

I also thought that it had something to do with encryption. In the security menu, where I turned off the display lock, it said that the phone is encrypted. However neither pin nor fingerprint could unlock the phone.
I had to go for ultima ratio and flash my device with the newest fastboot image and miflash (save user data option didn't work either, btw.).
I lost all data on the device, but now everything works fine and the OTA update also ran through without any issues.
Now, I'm not sure if I will fiddle with magisk again. I really don't have no clue about what went wrong at all...
Thanks

Thanks for sharing.
Maybe something to try for next time to restore data, I don't know.
I haven't tested yet but I did make a backup using the method explained here
https://9to5google.com/2017/11/04/how-to-backup-restore-android-device-data-android-basics/
I have yet to try (or need) the restore function but running that backup created a 6gb file. My understanding is this is the majority of your apps, data, messages, etc
Without twrp I was hesitant to root but with the bit of knowledge and files shared here so far I have moved forward and glad I did. I haven't had to flash the stock image yet but hopefully this backup helps ease the pain. It is nice to be able to modify at will

Please go see my guide, I just added a troubleshooting section that you should check:

Your feedback could improve it further.
No, flashing boot.img will not erase any data on the phone. But you must remove any PIN, password or screenlock before proceeding, or you could not access your data anymore (because of encryption).

Had the same problem. I tried to install the OTA of March, followed the guide to install OTA with Magisk, but after unistalling Magisk, i tried to install the OTA but it gave me this message "installazione riprenderà automaticamente quanto il dispositivo non sarà attivo";
I looked for some help online, but didn't find anything, so skipped to the point c, and i got this bootloop now.
I tried the "set_active b" command, but I'm still in bootloop. I tried to flash the stock rom but apparentrly it's impossible to do it without recovery (which I'm unable to open), so... Help?
EDIT: By using miFlash and using the flash_all command I flashed the most updated ROM I found on MIUI.en, which is the january's one. It worked, even if the build version (10.0.3) is different from the one I had previously (10.0.4). The system says that there's an available update, but i'm too afraid to try it. Suggestion are accepted!
