Same problem here. No solution found on the internet

Code from Ministry of Solutions works on my LDN-L21 !
But, on every reboot/boot you have to press Power button to continue or phone will continue boot after 5 sec.

Root and unlock could be done, twrp almost works. No custom rom yet, but no reason to hate LDN-L21.

Since Y6/Y7 (non)Prime 2018 has Android 8.0 -> support Project Treble +
we know that Y7 has ARM64v8 CPU and since many Treble check apps claim that our devices do not support seemless updates -> slot A only,
I assume that we can install custom ROMs in form of Generic System Image (GSI) made for Treble-supported devices!
For now, there are LineageOS 15.1 and Resurrection Remix 6, made by user phhusson.
- bootloader must be unlocked,
- boot.img remains stock (but patched with/for Magisk)
- recovery.img must remain stock, there are no TWRP or CWM for us.
- system.img can be flashed via fastboot mode (only way for now)
- must use stock erecovery to make clean install -> so backup all before, wipe data and do factory default!
It should (I say "should" because not tested yet) boot to custom OS (LOS or RR).
So, you can try, but I am not responsible for any damage!!! Choose GSI image for AMR64 A-only devices!!!

Did you tried factory reset after flashing system.img?
Custom roms (Lineage, RR, ..) have no /data encryption, also internal sd (/data/media/0), like stock rom does.
Maybe have to format /data as ext4, not f2fs ?
UPDATE:
Since we have 8.0 stock rom, we can flash Lineage 15.1 at most.

Sorry to read that. How did you format /data ? As F2FS or EXT4?
Just theory:
In /vendor, there are 2 fstab files that declare /data as f2fs and encrypted.
Maybe if remove encryption and remain as f2fs, it will work?
So, you could try to flash Force+Encryption_Dm+Verity+Disabler_HuaweiY7Prime2018.zip in twrp,
format(wipe) /data as f2fs,
flash gsi.img from twrp (flash image) or fastboot (fastboot flash system gsi.img)

I had this phone and it was a little tough to root it. However i did. First of all i used my friend's pc and his dongle to read bootloader code. I had a problem for unlocking it just like mentioned above. i resetted my mobile andgo developer option to enable the oem unlocking (internet is needed once to enable oem unlocking after a reset) and runned the command oem unlock xxxxxx again from minimal adb and it worked. NOTE unlocking bootloader is only difficult. after that everything is piece of cake. you can either use flash twrp recovery to flash magisk or super su zip or directly flash a patched boot image of stock rom patched by magisk. Once done reboot and install magisk app to get root access

For some reason no need to oem unlock (bootloader not locked properly??) so have twrp without needing to wipe data, but now remains the encryption problem as this trwp doesn't support it, I have compiled twrp for mtk in the past with encryption support but doubt I can recall what needed to be done
TWRP not working
When I install the TWRP recovery and start the phone with this mode to install the two files
1) no-verity-opt-encrypt-5.1
2) SuperSU-v2.82-201705271822
the phone does not see them and it is impossible to proceed further.
Furthermore, the operating system does not even start, so the original firmware must be replaced with the flash tool.
Has anyone found a solution to this inconvenience?
Thank you

1. Userdata is encrypted, and the TWRP here isn't compiled to be able to decrypt it. So you'll need an sdcard with those zips on it
2. The os won't start if it deems its been altered - that's partly what zip 1 is for.

No custom ROMs - I think there is a clone device [Panasonic Eluga C] so we have another stock ROM from them.
I haven't attempted porting anything yet, let alone building anything from source [a source built twrp should be trivial] - i've lost yet another hard-drive recently so light on diskspace & sdcards so not able to do much atm.
For completeness: stock ROM > http://ulefone.com/download/mix.html [newer than the one on needrom]
OTA > http://hwfotadown.mayitek.com/ota/r...NE_N_V0.6.9.1_S1712221514261911507/update.zip
Is this root method working?
Stock rom is located here Stock Ulefone Mix 4G Rom
when (android 8) Oreo for ulefone mix?
twrp and now?
Hello,
i have an old ulefone mix mt6750t with the screen damaged but still 90% working, i thought i would use it on android auto but i needed rooting.
So I informed myself a bit, go unlocked developer mode and usb, downloaded adb and twrp and magisk etc ...
I unlocked the bootloader from the settings then used adb and installed twrp which starts but asks me for the pass to decrypt, then I swipe and delete the encrypted data.
Then with adb sideload I install magisk 20 and check opt encript, but the phone always goes to twrp, it does not restart ... mmm and the orange mode message comes out but it should be normal ... someone knows how to go on to restart it normally and not with twrp?
Thank you

For some reason on my unlocked nokia 1 it started to ask password after flash and boot and gkeyboard always crashes on boot. So, I thought flashing fresh userdata might help.

I wrote in the instructions...
If you get a password just enter a random one, then it will ask you to wipe the device, click ok and it will reboot to recovery and then wipe userdata and boot fine.
just make sure you flash the recovery.bin and not twrp before you wipe

Same happened to me. I solved it by a hard reset via the stock recovery.
Make sure you flash the recovery.bin like Sooti said.
Wiping through twrp doesn't work.
Nice, working twrp for Nokia 1.
I buyed this phone today. Waiting for customs
A little warning.
It looks like the recovery.bin I took from another nokia 1 device doesn't match the checksum check which causes a failed during ota updates, please only flash this rom if you soft bricked your device.
If anyone can get me TA-1060 stock recovery image that should solve it. for now you can't update the phone until a fix is found
I have Nokia Ta 1066. Will this rom work on mine? Also I read somewhere Ta 1060 is single sim variant. What about the second sim?
Has anyone with TA 1066 tried it?
Thanks. Both methods work fine. Don't ask how I found out.....
Can you share how you managed to backup stock recovery file. Maybe after all the steps above we can flash our own device recovery to make ota work again...

Hey guys i have a TA-1056 and after unlocking bootloader and flashing TWRP it booted to recovery and came up encrypted, after looking around the only solution was to format data, afterwards when rebooting it always boots to recovery, i tried flashing this zip and i get the same issue and i can't find the stock ROM for the 1056 anywhere online, can anyone help me out? i really appreciate it

bootloader enter your imei it will give a key following all instructions precisely. it tells you the rxact command to use for unlocking the bootloader. after its unlocked, open your command prompt in your adb /fastboot folder. then adb reboot bootloader. after reboot phone will be blank screen. you have to download twrp 3.3.0.0 .img its the most updated. do that before the adb thing. then after adb thing, when you are booted into bootloader.....fastboot boot twrpxxxxx.img
this will boot into recovery. make sure you have magisk 19.zip doenloaded to your phone. then just flash magisk from the recovery, after reboot install magisk apk. there you go. sorry all of this is not in order. ive done it so many times im skipping ahead. i can give a better detailed and precise instructions if needed, litterally walk you thru it, if you need it. but the instructions provided by all the download sites are great. its easy peasy. if you need bettrr instructions youre more than welcome to get in contact with me.

you can keep the stock rom fyi. and theres an updated android 9.0 pie stock rom floating around too. im using it, no problems. you have to use xperifirm and flashtool to flash it tho. its simple unless its your first time doing, after you do it once youll ask yourself why it seemed so hard to get to that point. also, fyi, this particular is almost brick proof not saying it cant be bricked because, i did, several times boot looped it, everything, **** right now i dont even have a stock recovery because of some errors i made learning how to do all of this, but its up and running, its not buggy, magisk works great, stock android 9.0 firmware, just no recovery, but good ole twrp works just fine when you boot it for recovery. great phone to learn how to do all of this on. like i said its almost brick proof.

thanks Luk1337 for your work.
A) I get a stuck boot on SONY white screen when trying to reboot after a boot to twrp using fastboot (swipe to allow modifications and nothing else). Fastboot boot to TWRP was after a clean installation of Android Pie.
B) I even made a TWRP backup of the Android Pie rom but restoring backup runs into same issue of stuck on SONY logo). (well if just a twrp boot to resulted in a stuck boot (as in A) rebooting after a twrp backup restore would not have a chance either but just mentioning)
I am guessing we need a disable verity to avoid this?

[Solved][PX5 GS] Can not use custom recovery

I would like to flash custom recovery -> in order to use custom ROM -> in order to gain split screen in my 7" device (ehhh)
I have root, adb, access to bootloader (everything what I need..) but it does not work in default way.. - I mean flashing just by fastboot flash recovery TWRP.img
I have checked those TWRP builds
https://twrpbuilder.github.io/downloads/twrp/ (type px5)
Flashing worked fine (no error, success message)
But after rebooting to recovery I still have original recovery. Note: I have to reboot to system, and then to recovery by adb command. There is no reset button on my device, I can only enter bootloader by long pressing volume button while booting.
I saw `backup` partition in my device. Is it possible that system is reverting recovery partition? How to fix that so I can use TWRP

Good luck!
Please inform me if you will succeed.
Have you first tried to boot TWRP without flashing? I'd most certianly want to try that before flashing something.
Did that work?
This might sound super silly, but did you also unlock the bootloader first? (Sorry, I'm not familiar with your specific device so this may or may not apply in your situation)

Any advice is welcome thanks
But without unlocking bootloader I would not be able to go to bootloader and use fastboot tool right? So I concluded it is already unlocked.
I tried
fastboot boot TWRP.img
Image was downloaded and booted (success message was printed in console), I lost connection with device so it went in some other mode then bootloader, but after 30 seconds of black screen I have switch power off and back on to restart.

I tried using A8 roms but I can not flash it with original recovery.. It requires device name be PX5 (I have rk3368). If I remove checking from rom updater script, signature verification fails.
I have tried recovery from Malaysk pack (extracted from update.zip), tried RecoveryInstaller from malaysk, lot of TWRP which I have found in web.
Nothing worked.
However as a last chance I used bootable SD from Malaysk - recovery (for android 8) successfully installed, Malyask rom installed. Im happy now
BTW. If you want you system to not revert recovery - you need to remove "/system/recovery-from-boot.p"

By this you mean that you no longer need TWRP for android 8 ?

I mean I already have Recovery v8. So I was been able to flash custom A8 ROM.
However if you would implement TWRP please message me It is always better.

Except if you ever want to update your unit or MCU, then it's pretty much useless.

Maybe you are right. But at least it is easier to backup / restore whole device with TWRP.

Help With Lineage OS 18.1 Install -- stuck at first step(!)

Greetings,
Recently picked up this Pixel 3 and I like it hardware-wise but want to degoogle as much as I can (only want the bare minimum Play store to ensure I can use all my usual apps [nothing from Google - let me know if you need a list]).
Think that means I'll want to end up with Lineage OS 18.1 (Android 11?) + OpenGApps (Pico) + Magisk (for root?) does this seem correct?
Been reading a mishmash of this: https://forum.xda-developers.com/t/the-complete-pixel-3-how-to-guide-newbie-friendly.3922269/page-2 and other guides and I'm a bit confused.
I've rooted and imaged my previous Moto phone but it's been a while. From what I gather so far, the general plan for this Pixel is: oem unlock, usb debugging, unlock bootloader, boot recovery, install recovery, install lineage, install opengapps, install magisk, ????, profit.
However in the guide I linked, I see that the TWRP section is all red and strikethrough. And have read (perhaps old info?) that Android 10 and up TWRP doesn't work/support?
Yet every guide I've seen says to install TWRP and also the date on this OP is updated November 2020...? Plus, there are notes on the twrp page that just say mtp isn't working but otherwise that means it should work, right?: (https://twrp.me/google/googlepixel3.html)
I've unlocked the bootloader oem unlock, got the USB drivers and platform-tools installed (via most up-to-date Android Studio), see my device (Google Pixel 3) with adb devices, and can issue commands like adb reboot fastboot... I have everything this guide mentions ready to go, but I am stuck at temporarily booting recovery image:
Error output:
C:\Users\Nate\AppData\Local\Android\Sdk\platform-tools>fastboot boot twrp-3.3.0-0-blueline.img
Sending 'boot.img' (65536 KB) OKAY [ 0.232s]
Booting FAILED (remote: 'Unrecognized command boot')
fastboot: error: Command failed
C:\Users\Nate\AppData\Local\Android\Sdk\platform-tools>fastboot boot twrp-3.3.0-0-blueline.img
Sending 'boot.img' (65536 KB) OKAY [ 0.263s]
Booting FAILED (remote: 'Error verifying the received boot.img: Invalid Parameter')
fastboot: error: Command failed
The first command I realized failed because it was in 'fastbootd'... so I made sure to have it on the 'regular' fastboot, and get the second error. Invalid parameter... what's invalid?
This is what my screen looks like which makes me believe I've done right so far (attachments).
Feel incredibly humbled to be stuck at the first stage
Can anyone please tell me what I'm doing wrong or what I missed? Your assistance is much appreciated.
Thank you in advance.
TWRP has not worked on the Pixel 3 for a couple of years. I have not tried installing Lineage on my Pixel 3, but the process described at https://wiki.lineageos.org/devices/blueline/install should work. Basically use Lineage Recovery instead of TWRP.

Ok, thank you for the reply. I will go ahead and use the Lineage Built in recovery.
I wanted to use TWRP since before I actually start changing things, wanted to do a full and complete backup, basically a complete image of all files and partitions as is before I start changing things. I'll check the lineage wiki, but to your knowledge can you do a complete backup from lineage recovery?

Sorry, I have not used Lineage Recovery, so I don't know what backup capability it has.
Lineage recovery is just a modified stock recovery, it has no backup ability, only what is in stock.

Roger that. Thanks to dcarvil's guidance (pointing me to the correct instructions) I was able to successfully install and root.
I have some follow up questions, probably best suited for another thread. But while I have your attention, could you tell me where to report bugs or get general usage support? There's a few things that I don't think are working the way they're supposed to or features that seem missing. If you don't know, I respect that and a mod can close this thread.
Thanks again!
