[Need urgent help] Multiple issues on my Oneplus 3

I got my op3 phone loaded up with twrp version 3.0.2-1 but many errors occurred after I flashed this version.
Current problems on my phone right now:
-"The dm-verity is not started in enforcing mode" occurs every time I turn on the phone.
-Twrp won't read any of my files inside the "sdcard" folder wether it's just regular folder, .zip files, and even .img files.
-It also looks like only 1 version works of twrp works on my phone right now since any twrp versions after 3.1.0 causes the twrp program to froze and doesn't completely move past welcome screen of twrp.

I believe I had the same problem. Contact OnePlus on their support page. In a chat support window, tell the operater about your problem, and ask for an appointment with a level 2 technician. They should schedule you an appointment with a technician who should be able to wipe your phone no matter what state/condition it's in. They fixed my phone in a matter of minutes. But PLEASE, try to remember to be respectful and co-operative, it usually gets you better service no matter who you are dealing with.

For dm - verity problem, it's not a problem tough... Just a security breach as seen by Google.
BTW here is the fix...It's easy , follow the thread :
https://forum.xda-developers.com/oneplus-3/how-to/fix-easy-method-removing-dm-verity-t3544339
Can't comment on twrp as I'm on the 3.0.2-1, haven't tried 3.1. Hope it helps, Thanks!

Use TWRP 3.0.4-1. 3.0.2 can't decrypt internal storage, at least not on mine it couldn't.
Also if you have f2fs file system, TWRP takes a loooooong time to boot. Just wait, even though it seems hung. Takes several minutes. If you have ext4, it's quick. Use the app 'Diskinfo' to check

I had TWRP 3.1 and it would not do OTA of lineage, it would wipe the device when I tried and would not restore backed ROMs, stay away from TWRP 3.1. So, i went back to 3.0.4.1 via fastboot. My suggestion is flash the stock recovery from Oxygen 3.8 marshmallow (this can be found in the archived OnePlus 3 tool kit on XDA) and then sideload the stock marshmallow Oxygen 3.2.8 (download from OnePlus support page) and start all over.

That doesn't make sense..
The latest recovery works fine here, atleast the official one. If you are in F2fs and encrypted keep in mind it takes a long long time since F2fs is really bad at this.. Depending in how full your internal storage is it can take up to 10 minutesm

Twrp 3.0.4.1 or
3.1.0 x v.26 blu_spark.
To get OTA you need to be stock, only Oos official stuff.

I do have my oneplus 3 formatted as f2fs, but it is not encrypted. I don't know what happened to it when I tried to do an update with lineage os it basically factory reset the phone (and no I didn't wipe anything but the cache) and it would not install any zips from my internal sd card. I had to go back to fastboot and reflash TWRP 3.0.4.1 recovery. Then I wiped the device and reinstalled lineage, now it works perfectly fine.
They are lineage nighty OTA updates.

Decrypting the phone and flashing new ROM

Last weekend, I decided to flash a new ROM since the one I have been using is no longer being developed. I flashed a LineageOS nightly build because I used to like Cyanogenmod and heard Lineage is a continuation. I do like the ROM overall, but for some reason it encrypted my phone during install. I did not want it to do this, it just did it without asking me (when I first got my phone, I remember I was having problems with it being encrypted, with my recovery and such).
Is there any way to reinstall LineageOS without it encrypting the phone? If not, how do I decrypt the phone again and get back to basically stock + root? I downloaded the most up-to-date stock 7.1.2 ROM from Google, and was going to just flash that, but it wouldn't let me in TWRP (said the zip was not valid). I also tried rolling back to an older backup (not LineageOS), but the phone never booted.
FYI - I use Linux Mint and have the latest adb/fastboot, and the latest TWRP for Nexus 5x.
Thank you if you can help.

If you want to flash stock rom you have to flash it via fastboot. The instruction is on the Google download side. But if I remember right you have to wipe everything so make a backup of important data.

If I format my "userdata" with fastboot to get rid of the encryption, do you know if it will delete my ROM backups? I think the encryption is why I'm having trouble going to another ROM from LineageOS. I REALLY wish the ROM would simply ask you before deciding to encrypt the phone. I have no reason to encrypt my phone, and I don't want it encrypted.

[ROM][9.0][UNOFFICIAL] XenonHD

Another nice (treble) ROM for Oneplus5 (cheeseburger).
No fancy intro, no long list of features...just try it for a couple of days and if you don't like it - toss it and restore your previous rom!
ROM: https://androidfilehost.com/?fid=11410963190603857500
built using
- ROM source: https://github.com/TeamHorizon
- Krieg kernel: https://github.com/Krieg-Kernel
- GZOSP: https://github.com/GZOSP-Devices
It's still in its early 9.0 stage, not many settings are implemented yet. I can only promise to post a fresh build as the dev.team adds new features.
Tried & tested on my own OP5 (decrypted) after having installed OB19 firmware (tried also 5.1.5 and it's ok, too).
IF YOUR device satisfies those conditions then, installation is straightforward:
1. In TWRP wipe dalvik/cache/system/data/vendor
2. In TWRP -> install ROM and (if you wish) opengapps/magisk
3. add noverity
4. flash
5. reboot
6. enjoy your new ROM

sha fa ！chinese man will try

Excellent new rom and like the mantainer (you other roms)
All is fine, there already all the stuff for a daily usage, really (AOD, AudioFX, QS Columns/Rows numbers, etc)
Just a little thing for me is essential for keep this rom :
- Disable / Enable HW Buttons & Backlight
- Button Mapper
Good job mate, for sure i will try the others builds

Hello
It's looking a good base with stable kernel, but need to fix :
- battery menu crashes
- no traffic in/out visible after activation
- notification slider button on side left are not working
Can you check?
Thanks

Try
I'd try it later.

I tried to 'fix' the slider but it doesn't work as it should
The phone reacts to the notif.switch but stays at 'mute' when you go back to the bottom position.

Noob question, but in TWRP what partitions do you need to backup (treble rom) in order to restore it, should you not like the new rom you've just flashed (so to speak)
As I'm using the latest Blu_Spark TWRP, but a little unsure of what to back up... some info here, but to be honest it not really that clear (unless i'm misreading it) : https://forum.xda-developers.com/pr...o-choose-nandroid-backup-twrp-please-t3839546

The ones that are selected as default are enough. I have the latest twrp from codeworx and on backup, the selected partitions are: boot/system/data. In previous versions of twrp (from codeworkx) there was also vendor partition. Here's also a pic of my twrp screen when i do backup.

Yes it's the vendor partition that's a grey area for me. As I know the vendor partition is for treble enabled roms (I believe).
So if I was to backup Boot, System and Data (like your photo), then backed that backup to a PC (not forgetting the contents of the SD card folder), did a Format data, flashed a new rom and disliked it (as I do flashing between roms). All I would need to do it copy the TWRP backup back onto the phone, and restore that backup via the TWRP. I know it's pretty simple, but always best to be sure.

You dont have to format data if switching between custom roms. Do a backup of your current rom (if your twrp version has also a "vendor" partition selected then leave that, too). Then just follow the standard procedure: wipe system/data/cache/dalvik, flash the new rom and your twrp backup(s) will still be there. But if you FORMAT data, as you said, then of course you need to first save the twrp backups to your pc.

LG V500 Tablet - Nougat Upgrade Problem (Lineage File)

First off I'm no tech guru, so please provide as much detail as possible if you can so I can follow along... TIA!!
I am trying to upgrade my old LG V500 from KitKat 4.4.2 to Nougat.
I followed details in a video, by downloading the necessary files....
-Latest TWRP App (the APK)
https://dl.twrp.me/twrpapp/
-Latest TWRP Recovery for the v500
https://dl.twrp.me/v500/
-Stump Root
https://forum.xda-developers.com/lg-g...
-LineageOS build for the v500
lineage-14.1-20180909-nightly-v500-signed.zip
I hit Install and selected the above Lineage file and swiped to confirm the flash in TWRP.
What I got was this error...
https://drive.google.com/file/d/12ZY3y9pNaRJxqWHuCJSEmyl5Xmn3CtXq/view?usp=sharing
Now I am confused on what to do. I don't want to lose my old 4.4.2 build since this upgrade didn't work.
I could really use some serious help on what steps I should take. My preference would be to upgrade this tablet, but if I have to revert back then so be it (but don't even know how to do that). Wondering if I did something wrong or this .zip file is just outdated, not sure what else 'Error 7' refers to, other than Error installing .zip file.
Any help would be appreciated!

Most likely that is the case, rom file is two years older than the recovery. You can either:
1. Install newer version of Lineage with that recovery: https://www.los-legacy.de/v500
2. Flash older version of TWRP first and then install that older Lineage, or some other rom (for example I have TWRP version 3.3.1-0 and Resurrection Remix N 5.8.5 FINAL which works flawlessly https://forum.xda-developers.com/lg-g-pad-83/development/testing-resurrection-remix-n-5-8-3-oms-t3601456)

Thx Indie Zex for the options.
My dilemma now is, how would I install this new Lineage with the recovery file, since I am still in TWRP?
Need help on what steps I need to follow to either exit out of TWRP to get the newer Lineage file.
I assume you can't load anything from the link you provided while I'm in TWRP....am I correct?
If I exit out of TWRP now, will I completely lose my original 4.4.2 (KitKat) build?

If I understand correctly, you are still in TWRP on your tablet right? If you performed full wipe of Dalvik Cache/Cache/System/Data (like you always should do before installing a new rom) then you can kiss your KitKat goodbye forever! If for some reason you didn't wipe anything, then in the main menu of TWRP you can select Reboot, then System and your tablet should (luckily) boot into KitKat. But lets say your tablet is wiped and you now have to install new rom:
1. On your computer download https://www.los-legacy.de/v500 and open gapps https://opengapps.org/ (ARM, 7.1, pico)
2. Connect your tablet with computer via usb cable and copy both rom and gapps to internal storage (Windows should see your tablet as a mass storage device no problem even if you're in TWRP and you have proper LG drivers installed)
3. Now on your tablet: from main menu go into Wipe, then Advanced Wipe, then on Select Partitions to Wipe page tick Dalvik Cache/Cache/System/Data and Swipe to Wipe
4. Back to main menu and select Install, then find rom from the internal storage, then Add more zips and find gapps and finally Swipe to confirm Flash
5. Once that's finished press Wipe Dalvik Cache/Cache and then Reboot
That should hopefully be it.

TY Indie Zex,
You understood correctly, and I did a full wipe of Dalvik Cache/Cache/System/Data. I was afraid you would say I lost my old 4.4.2., but I really just wanted some insurance to go back if things got messed up, which they did!
For the legacy OS, I assume I should be going with the very latest lineage file (2020-09-05 date)?
Question about Nougat vs Q or Pie - If I pick Nougat, is there a compatibility upgrade/update path via Nougat OS to get to Pie or Q, easily within the software just by selecting 'Update' option in the 'Settings'?
or if I ever want to add the latest Android OS like Pie or Q, I would have to again go thru the full swipe and re-load another ROM and the specific gapps for either Pie or Q.
I assume Q is still quite new and maybe buggy, but is Pie now very stable or still some unresolved issues? I know it might be difficult to answer, as there are always bugs in firmware version. Just trying to get a gauge for which would be safer to go with if I need to upgrade.
TY you again for being patient with a newbie

You always flash custom roms the same way in TWRP, you can not just update unfortunately. The next thing to pay attention to is to download correct version of gapps for Oreo or Pie roms (there are no Q roms for our tablet). You have probably seen this tutorial here for Pie https://forum.xda-developers.com/lg-g-pad-83/general/guide-tutorial-howto-lg-gpad-8-3-v500-t3967069. I have tried it as well as https://forum.xda-developers.com/lg-g-pad-83/development/rom-crdroid-android-t3772076 but they both have broken camera unfortunately. Everything else is basically fine, with Oreo having better performance.

Rhetorical questions.
What's wrong with pressing the THANKS icon under Indie Zex's answers instead of writing "TY"?
.
Besides, if you were advised to install a very stable Nougat, why don't you try it first, before thinking about P and Q?

Yes, I did see the Pie tutorial and did read through it, the non-working camera was certainly something I did not want. Good to know you have Oreo running on yours, and better performance.
So do you suggest I load Oreo vs Nougat?
For Oreo would I select v8 or v8.1? and what variant?
I found this info...I was thinking of Micro or Mini, thoughts? Can the V500 handle the memory requirements for these?
Variant:
Aroma: Graphical installer of the super package while in recovery menu, it allows user to select which applications to install.
Super: Includes all Google Apps that were ever shipped on a Google device.
Stock: Recommended package that contains all Google Apps that come standard on latest Nexus/Pixel phone.
Full : Very similar to Stock version.
Mini : Smaller set of popular Google Apps with extra functionality.
Micro: Limited set of Google Apps with Gmail, Calendar Google Now with extra functionality.
Nano : Minimal installation with extra functionality.
Pico : Minimum with Google Play functionality. (Each package varies with file sizes and included Google Apps)
TY again, much appreciated!

Since you already have latest TWRP version installed, I suggest you go with latest lineage rom (2020-09-05) with gapps of your choice. For Oreo and other older roms you need to flash older TWRP version, such as above mentioned 3.3.1-0 (and please do not ask how ).

Camera (and everything else) works on all Nougat (and earlier) roms. Differences between them come down to customization: for example Resurrection Remix N 5.8.5 FINAL and crDroid Android 4.7 offer more customization options compared to LineageOs, but are two years old. Latest Lineage, on the other hand, has literally last month security patches. And I suggest you install them all, one at a time

Hm, the error suggests that you have 6.0.1 rom which you tried to flash with 7.1 gapps. Just in case, download older version twrp-3.3.1-0-v500.img and flash it in TWRP:
1. Copy twrp-3.3.1-0-v500.img from computer to internal storage of a tablet
2. In main menu of TWRP select Install, then Install Image
3. Choose twrp-3.3.1-0-v500.img and flash it (IMPORTANT: do not reboot right away!)
4. Go back to main menu then press Reboot and select Recovery
5. You will boot to recovery again, now the older version
6. Now flash rom ONLY (whichever Nougat variant you want) with standard described procedure (with wipe and everything) and reboot
7. Once you are in system, check it out and come back later into TWRP to install correct gapps (yes, you can use micro)

Hi Indie Zex,
I read your above instructions, but somewhat confused.
I looked for twrp-3.3.1-0-v500.img but can't seem to find it, has the file name changed?
I went to the link page you provided (below) for your Resurrection Remix build, and the Rom available there was RR-N-v5.8.5-20171001-v500-Final.zip
2. Flash older version of TWRP first and then install that older Lineage, or some other rom (for example I have TWRP version 3.3.1-0 and Resurrection Remix N 5.8.5 FINAL which works flawlessly https://forum.xda-developers.com/lg-...3-oms-t3601456)

Yep, that is the "newest" one which I have installed. If download link is broken, you can get rom from here https://androidfilehost.com/?fid=4349826312261778561

Before I try to flash my tablet with twrp-3.3.1-0-v500.img, what do I need to do with the lineage-14.1-20200905-UNOFFICIAL-v500.zip that I ran and is still in Internal storage. Can I just delete via my computer, or do I need to remove it thru TWRP?

If you don't need it anymore, you can delete it via computer. It doesn't really matter when you install .img file. When you select install image in main menu of TWRP you won't see any other files except for .img ones. Just make sure to reboot to recovery instead of reboot to system to continue with installing rom.

Great TY.
So from yesterday when my install failed, I just need some direction on what do I do to get out of this screen, please.
I have the option button to Wipe Cache/Dalvik or Reboot System.
Do I need to hit the Wipe button to remove the lineage-14.1-20200905-UNOFFICIAL-v500.zip? Or Wipe anything else?
Or do I just go back to the main menu for TWRP and install the twrp-3.3.1-0-v500.img and follow the rest of your instructions?
TY again.

Full Nandroid Backup Solution for LineageOS 17??

I got Lineage 17 w/ Magisk root running now neat and great and I want to perform a full NANDroid Backup.
After some research it seems crucial to have a custom recovery like TWRP for that. There is the online nandroid thing - but I would need CWM or anything like this to restore?!
So my question is
a) is there another custom recovery (compatible with Pixel 3a XL w/ lineage 17 based on android 10) I can install and perform Nandroid backup with?
b) any other solution to perform this backup and restore? I heard there are cmd commands for that as well , but I'm a noobie not so sure to do that.
of course there are several apps out there to backup data.. but I don't trust ''any'' app to get root permission. In F Droid I couldn't find what I was looking for. Suggestion?
thank you for help!

It is unsafe to perform backups while booted into Android, as files may be changed/added/removed while the backup is taking place.
This is why it tends to be a feature of custom recoveries.
Titanium Backup is good. It doesn't support split APKs like YouTube but the data restore works flawlessly. This is an old utility app so you can trust it with root. You can find Titanium Backup on the play store, it is the one with the star and "root required".
If you want to perform full backups of your PHONE you will want TWRP. If you want to perform full backups of your APPS then you will want to use an app like Titanium Backup (however Titanium Backup is not updated for split APKs, like I said above), which will allow you to transfer your backups to a new phone and fully restore all apps & data (as long as both phones have root).

Sure problem is I want to perform a full backup of my phone, but TWRP ist not available. What are my options?

Does TWRP for Pixel 3a XL not work for you? All you have to do is download the "twrp-installer-3.4.0-0-bonito.zip", install it as a Magisk module, then direct install Magisk again, then reboot into recovery and you'll have TWRP.
When accepting OTAs, you will want to use the "TWRP A/B retention script" before you install Magisk to the inactive slot. The script is available as part of the Magisk modules repository, so you should be able to install it directly from within Magisk Manager.

TWRP doesnt work for me, see here what user 41rw4lk wrote, too..
Is there a tutorial on how to install twrp as a masgisk module?
Also, how else can I perform a backup img for my phone?
thank you

Benn trying to get this to work for a little bit now and no luck at all....
Let me start by saying i an NOT running LOS so that might be the whole issue...
I have tried with pure stock and stock with ex kernel
Same results for each
1) TWRP loads as the recovery and can be booted into, BUT the rom is now soft bricked and wont boot at all
2) Even when in twrp I cannot flash anything, cannot see sdcard and cannot backup data partition (the data partition shows as 0 space)
Perhaps the LOS kernel or rom adds something thats missing in my two setups?
The sample video is for another phone. My recolection is that twrp and pixels on android 10 or 11 wont work. Lineageos 17.1 is android 10 based. I think it worked on that other phone as it was not a pixel.
Can anyone confirm or deny if this works in any configuration of android 10 or 11 on our phones?

Huh, that's weird... I apologize, I'm not very good at supporting devices I don't own. I'm not running Lineage either, I'm running stock plus mods.
It's possible that it doesn't work on your phone for whatever reason. There are a couple ways to install TWRP nowadays, check them out maybe? I promise TWRP is what you want for backups.

Agreed but twrp simply doesnt work on our phones, or even any pixel 3 or above. It can't read the partitions correctly. Just trying to keep people from soft bricking their phone. Something about andriod 10 and 11 and the phones a/b partition configuration

Where did you hear this? I'll admit, I haven't heard about TWRP not working on Pixels, but it's relevant and it would be good to know if I ever help another Pixel user in the future.

That's interesting, because my OnePlus 7 Pro runs Android 10 with an A/B configuration and TWRP works just fine. Haven't found a single feature that didn't work. Flashing custom ROMs, changing boot slots, etc. all work fine. So it can't be the A/B configuration.

No method I have tried results in anything but an unusable twrp or a boot loop. Cant even fastboot boot current version. All about dynamic partitions and lzma compression as I guess the partition isnt big enough. But bottom line is I have yet to find anyone including myself who can get twrp to in any way shape or form be usable on our phones for android 10 or newer.
this is what command prompt gives with fastboot boot
Sending 'boot.img' (65536 KB) OKAY [ 1.509s]
Booting FAILED (remote: 'Error verifying the received boot.img: Invalid Parameter')
This is likely due to the kernels I use likely not having lzma. Checking into it.
fastboot: error: Command failed

I'm not sure how reliable is that. I just did a backup of Lineage 17 in TWRP, System and Data, restored it a few hours later through OTG and it got stuck on a google boot screen... Now I installed the LOS 17 ROM again (which I had in internal storage) but restored only Data (excl. storage).
It boots up now, but most apps are corrupted - if I open them they crash ('App ... keeps stopping').
I wouldn't count on it. TWRP nandroid backup is very unreliable.
