No, but ROMs decript just fine as stated by [MENTION=4385555]the Doctor[/MENTION]

TWRP will decrypt keymaster 1 until you flash an 8.1 ROM, then keymaster 3 is there untill you format /data and going back to a 8.0 ROM will lead to TWRP not being able to decrypt. You have to remove PIN and go from there if you need to access your data on TWRP.

It's a workaround many are using, but this in the end could lead to a user getting locked out both on TWRP and Android, probabilities aren't that high for this to happen though.

This is valid both for codeworkx and blu_spark TWRP for the time being.

LOS recently introduced some crypto changes with February security updates, so going there will break TWRP decryption for good until new TWRP updates come through.
[OnePlus 5T  Guides, News, & Discussion] Macusercom:
Okay, thanks. So going from OOS 5 to LineageOS 15.1 will be fine and I'd be using Keymaster3 then. This is the only thing that interests me. I want to upgrade to LineageOS once it's official and I do not want to format anything on the SD card. Once there is a working TWRP, I'm happy. I feared needing to wipe internal storage to use LineageOS 15.1.
[OnePlus 5T  Guides, News, & Discussion] Chaplan:
You don't but then...

Rule of thumb:

An internal storage backup is always advisable.

Nobody needs one until they do.
[OnePlus 5T  Guides, News, & Discussion] Macusercom:
I always have one but it's easier to not have to restore it ;)
[OnePlus 5T  Guides, News, & Discussion] ddaharu:
Isn't it possible to decrypt the 5T by formatting data in twrp?
[OnePlus 5T  Guides, News, & Discussion] the Doctor:
As I say in the OP, I'd prefer this thread not devolve into a discussion about decrypting. There are a couple threads in the How-To section about decrypting if you want to.

Can come back to oos from custom rom without formar data? With bluespark twrp

[OnePlus 5T  Guides, News, & Discussion] djmcnz:
Hmm, FWIW I lost /data and /sdcard reverting from OB4 to OOS 8.0.x using nandroid.

1. Encrypted but no lock screen security I made a nandroid of 8.0 /system /boot /data

2. Upgraded from OOS 8.0 to OB4 using TWRP (dirty flash)

3. Booted to 8.1, everything was fine, all pre-existing apps were fine (except Nova launcher glitch)

4. Eventually rebooted to TWRP and wiped /system /data (not /sdcard)

5. Nandroid restore /system fine

6. Nandroid restore /data failed

7. Reboot to System and /data and /sdcard gone (factory reset) but system is back to 8.0

So I don't think all encrypted users can assume 8.1 -> 8.0 is possible. :(
[OnePlus 5T  Guides, News, & Discussion] Chaplan:
Odd, or maybe not.

I used blu_spark TWRP (latest version)

Removed PIN on 8.1.

Booted TWRP, wiped /data (without wiping /data/media), cache, dalvik/ART and /system.

Flashed 5.0.4 full zip.

Restored Nandroid /data backup. (No error on output, restore was flawless).

Reboot to Android and all is good, internal storage is as it was.

Assuming you didn't format /data, you clearly state you haven't.

Maybe different TWRP, maybe wrong FW (8.1) since you restored system instead of flashing the ROM full zip which will get 5.0.4 FW up and running, from what I can see on your posted workflow.

Set up PIN on 5.0.4 afterwards and TWRP decrypts fine.

Restore works and Keymaster 1 it is.:(

is it still present the issue that TWRP isn't able to decrypt the phone when you come back to OOS after custom rom?

[Wiko Rainbow Questions & Answers] Rem33127:
Hey there

I am trying to factory reset my phone without recovery.

A day I was trying to install TWRP but I forgot to unlock bootloader -_-

So I can't access recovery. But I have downloaded the recovery.img frol the official wiko website, but I don't know how to install it.

Or, if it's possible, making a factory reset without recovery.

I can access to adb, but I think fastboot isn't accessible because when I reboot on bootloader it's blocked on wiko image.

I have root but since I have uninstall SuperSU app accidently I think it's doesn't work, because the deny/allow window respond approximately after 15 seconds but the notification "app has been granted super user permissions" isn't displayed.

At the startup I get a message who say's my phone has an internal problem and he will not work properly if I don't make a factory reset.

Sorry for my English, I'm french :laugh:

[EDIT 07/01/2018 - 15:39]

I have searched for installing stock recovery.img file via adb, and I found that post : goo.gl/JhmEx4

I have make a factory reset, I'm still waiting for result, I'm blocked at Rainbow LITE 4G image at the moment.

Find the latest .kdz and use LG UP or LG Bridge to install and this will return your G6 yo stock and remove TWRP.

Use lgup and uppercut to flash stock kdz file

If you're wanting to send it in for warranty repair the boot loader will still be unlocked, flashing a stock kdz will not relock it. They may not honor the warranty.

Hey,

I'm currently using DCD's GPS rom along with the 3.27 radio, so most everything hogging memory is killed off, GPS is working and for the most part I haven't changed the Registry or installed many apps.

The problem: When I receive calls from friends they often complain that they have to wait 4-5 rings before I answer. Typically I see the phone call and answer immediately, and even when this happens I get the complaint again: "Why does it take you so long to answer your phone?"

I have created several small, personalized Ring tones, in the memory area of 50-70k. I've heard that full sized mp3's can take a moment to load and subsequently this creates a problem...but in this case I wouldn't expect it to be.

Does anyone have any suggestions or advice? I'm considering calling Verizon, who is my subscription carrier, but I'd prefer to try to figure it out.

Thanks much.
[Mogul, XV6800 General] aatreya:
I have this problem with Sprint too. I agree - it's EXTREMELY frustrating. You can try lowering the Slot Cycle Index (SCI) on your phone, but I already did this and it didn't help much at all.
[Mogul, XV6800 General] friguy33:
I just posted a similar question, do u have data? i noticed if i turn off data, it answers the call much faster, then if i turn it back on, it goes back to the same slow answer problem.
[Mogul, XV6800 General] scotcha12345:
data

This is all the time, not just when I have data. Definitely a bummer.

I haven't heard of the cycle changing you spoke of, how do I go about doing that? Or is it of no real purpose?

from all i know, its mostly all talk...no change with the cycle stuff

I had this problem as well. It was frustrating enough to cause me to hard reset. After the reset, calls answer right away.
[T-Mobile Samsung Galaxy Note 8 Questions & Answers] reukiodo:
I have access to an engineering bootloader for the Tmo Note8 and I would like to know how to test if it is unlocked.

Is there a specific process to determine if the bootloader is locked? Are there steps to permanently unlock the bootloader from an engineering bootloader?

I've searched all the Note8 forums and haven't found any answers.
[T-Mobile Samsung Galaxy Note 8 Questions & Answers] Gizmoe:
Flashing it and then checking if you can unlock it would be how to go about it. Except you can't flash unsigned images without unlocking so it's a catch 22 really. And it may just brick your phone even if you flashed it successfully. No way of knowing if that bootloader will even boot your device or play nice with the other partitions.
[T-Mobile Samsung Galaxy Note 8 Questions & Answers] reukiodo:
The eng bootloader is signed, so there is no problem flashing the eng bootloader. I just do not know how to test if it is unlocked, as I can't find a recovery image to flash, and I do not know how to create one myself.
[T-Mobile Samsung Galaxy Note 8 Questions & Answers] Team DevDigitel:
probably just the combo files that are used for samfail imo. if you want to upload and have me check them lmk but more then likely all you have is the combo firmware we have been using since day one

[T-Mobile Samsung Galaxy Note 8 Questions & Answers] Team DevDigitel:
Do you have the boot.img that matches this?

Unable to check the rest without as it won't boot the combo img.

Yes it is a eng img.

We are on multi csc devices so all are same for flashing sake, as long as it's not the exynos.

Please remove the public link and we can move to pm/telegram and speak further
[T-Mobile Samsung Galaxy Note 8 Questions & Answers] reukiodo:
I disabled the link, though not sure why I should? I haven't gotten telegram yet. I just want to know if it is unlocked for flashing custom recovery such as TWRP.
[T-Mobile Samsung Galaxy Note 8 Questions & Answers] Team DevDigitel:
No one has compiled twrp for snapdragon because we dont have a unlocked bl. Removing link is primarily to avoid people flashing this or reposting it with incorrect info and causing confusion.

If I can get the boot.img as well that is compiled for this bootloader I can get a running system and see if it can be unlocked. Otherwise without it there's no way to determine some of the important factors here. Just flashing against device to test is quite risky.

The bl is compatible with all snapdragon and does install correctly but it won't boot with the combo imgs we use for samfail or a stock img.

Link is still active fyi and I've sent you a pm with telegram info. It's a group for us and a few other devs that can work with us to get things sorted.
[T-Mobile Samsung Galaxy Note 8 Questions & Answers] DroidisLINUX:
I used the engineering bootloader with Odin, after it flashed showed it as an eng boot loader not user, says Samsung official and is still locked. I booted with a binary .img booted and oem option from the settings was there, showed the same unlocked img on boot as samfail also. But I didn't do much other than check those things. I tried to load samfail system but it didn't load I figured as much seeing samfail boot.img is user-test not user-release and has custom binary but I don't know that much

I am wondering if we don't have to leave the eng boot loader on and oem toggled for a week like exyos versions before we can flash custom binary
[T-Mobile Samsung Galaxy Note 8 Questions & Answers] Eudeferrer:
I'm wondering if after flashing this engineering bootloader we can root phone just by simply using command prompt and sideloading root files. Any ideas? I don't know enough to do this.
[T-Mobile Samsung Galaxy Note 8 Questions & Answers] DroidisLINUX:
I don't believe so, until we can get it unlocked, when in download mode it says the boot loader is still locked and says system secure in red and official binaries but if we can get the boot loader to say unlocked then I believe it will probably be possible. At least it says eng boot loader and tells us it's locked and that means it can be unlocked it's just a matter of time until someone gets it unlocked now

I am glad I haven't updated to boot loader 3 now, this is bootloader 2 so if you go to oreo you won't be able to use this when and if it's unlocked
[T-Mobile Samsung Galaxy Note 8 Questions & Answers] Eudeferrer:
Has anyone tried the same procedure/comands used to unlock the Pixel XL? Would they even work I this phone if it had this eng bootloader? I wish I knew enough about this stuff to try it out or even know if it would work.
[T-Mobile Samsung Galaxy Note 8 Questions & Answers] Team DevDigitel:
you could test,

but if you look under the info on the boot up screen, secure boot is still set to : enabled

IE: each and every boot it checks for a modified boot.img and if found it fails secure check.

I never tested the oem unlock options etc, or waiting any time frame, just mostly seeing what we could use with it.

The phone wont boot a modified system as well. has to be unrooted stock system + stock boot.img to boot with the eng bootloader.

Unfortunately i havent heard anything back, was hoping we could get the boot.img that is ENG so we can boot the entire setup and go.

Trying to test the feature before I go overseas. Wifi calling is enabled, HD voice/advanced calling enabled. When I check the hidden menu in *#*#4636#*#* everything is checked.

Had same problem with Verizon Wifi calling, fixed it

I had the same problem on my OG 2016 Pixel (rooted) running stock 7.1.2 ROM on VZW, but now fixed - here are the steps:

1. Open Testing Menu (dial *#*#4636#*#* on dialpad).

2. tap the "Phone information" menu.

3. Toggle on the "VoLTE Provisioned" slider (this was toggled off by default on mine). (Also make sure "Wifi Calling Provisioned" is toggled on.)

4. Using the Quicksettings dropdown menu, toggle Airplane Mode.

5. IMPORTANT NOTE - When I tried the 1st time it didn't work because entering Airplane Mode greyed out Wifi icon and disabled all Wifi connections (and data icon showed "no service"), even though Wifi was previously toggled on.

6. To remedy this, drop down your Quicksettings menu again and simply touch the Wifi connections shortcut, wait a couple seconds and all Wifi connections will repopulate, and default Wifi connection should re-connect.

7. Now hit the back button to the Quicksettings dropdown menu, wait another couple seconds and the data icon should change to "Verizon Wireless Wi-Fi Calling" - Wifi calling should now work
[Google Pixel Questions & Answers] Celeras:
I appreciate the suggestion. I had tried toggling all those options previously but I did it again per your instructions. It did not work.

My quicksettings text goes from "Verizon Wireless" to "Airplane mode" when it is enabled. Then when I put WiFi back on it goes BLANK. It does not say "Verizon Wireless WiFi Calling" like yours did. Any ideas?
[Google Pixel Questions & Answers] baknblack:
I don't understand. I have a cellular signal and my wifi calling just stays on. All I did was change 2 values in the Database.
[Google Pixel Questions & Answers] Celeras:
Yes thanks, I already established I am not trying to get it to stay on all the time.
[Google Pixel Questions & Answers] baknblack:
I guess I never caught that fact. Mine doesn't stay on all the time. But, as soon as I walk in my house it pops on. My wife has an S7 and I can't get hers to work unless I turn the cellular off. Evidently Samsung does not have the same settings database.
[Google Pixel Questions & Answers] Preterist:
Perhaps a local router misconfiguration?

I've heard that a local Wi-Fi router mis-configuration may be the reason Wi-fi calling fails in some instances.

I would test it out on a different router, or have someone with a known good Wi-fi calling phone setup test on your router to eliminate that possibility.

I've also heard that Wi-fi calling breaks when upgrading to Oreo for some folks. Curious what Android version you're running?
[Google Pixel Questions & Answers] Celeras:
Hmm, I will give that a shot next time I can. All my tests have been on my home wifi.

I ran into the same issue, possibly after Magisk install on custom RR Rom (Marlin/Latest April Oreo build). It had worked one time but I guess installing Magisk was the most recent change I could think of after which it stopped working with the error message reported by OP. Anyways the only thing that worked was to do a "Network Setting Reset" , then setup Wifi (Airplane mode on) again and Wifi Calling settings back to On with Wi-Fi preferred.

Note: Also in "Mobile Network" in Settings, need to ensure "Roaming/Connect to data services when roaming" option is selected for the "Wifi Preferred" option to stick.

It was my router - when i turned off QoS (Quality of Service) in which I had a few rules set up, the problem went away immediately without rebooting anything. So for all u reading this, it might be your own equipment, not your phone at all! After three days of going way too deep in my phone, I'm just relieved that I can text and call via wifi again.
[Google Pixel Questions & Answers] arbarpixel:
same problem!

Hi. I have the same exact problem. I have a (temporary) fix though. I get the same error. I thought I was crazy when I went in to the Verizon store, and it suddenly worked. I even reset network settings as per the tech coach, which created a huge amount of work for me. However, once I got home, it stopped working.

In the end, after working with my employer's IT team (I was convinced it was their wifi and infrastructure problem), and connecting to a number of different wifi servers (with varying security levels), I figured out that I can force wifi calling to work by setting everything up, connecting to Wifi, getting in airplane mode (with wifi on), and resetting my phone. It worked for calling and texting. However, once I lose that Wifi signal or move to another wifi, or turn wifi off, and then back on, I immediately get the error that you do. Then, when I restart the phone, it works seamlessly, until there is some change in wifi signal.

Clearly, this is a problem where the prior setting is locked in place. This doesn't impact using data in any other way besides android messages and the phone app. I can use WhatsApp, no problem, as that is a simply data issue, just like using Chrome.

So, thinking I was brilliant, I went to the Verizon store today, and I recreated the problem, both for me, and for the rep. He told me I needed a new phone first, but I showed him how it even happened on his phone. Then, he couldn't figure it out (wasn't too technical, actually), and the manager came over. She proceeded to make a ridiculous move, which simply wasn't sustainable. She turned off my mobile data settings. After that, things worked. She claimed that was the solution. Oddly, she couldn't seem to understand that this inhibited me from using mobile data without turning that toggle back on. She was convinced that this was part of the wifi calling menu, which it isn't (wifi calling is a submenu of mobile data, under advanced). Either way, she was really nasty, so I stormed out, left to desperately search the web for an answer.

If the restart and mobile data tricks trigger any thoughts from anyone out there, please help. This is incredibly annoying. I need to have wifi capable text and calling for work, as we have no usable Verizon signal in my building, and I depend on this for communicating with my colleagues.
[Google Pixel Questions & Answers] post-mortem:
What if you connect to the WiFi network first, then turn on WiFi calling, will it work? When you want to leave, turn WiFi calling off first, then disconnect from the WiFi network, connect to next WiFi network, then turn WiFi calling on again. If that tedious process works, you may be able to enable WiFi calling via a script.

Also, see this post, and the linked thread, especially the line

settings put global wfc_ims_mode 2
