Hello
I had my phone on the VNS-L31C113B132 firmware, unlocked, rooted.
Then I got a message about a new update (VNS-L31C113B141), so naturally, I downloaded the update.app and tried to flash it through twrp with no success, so I used the up+down+power method, it worked, and all was well, except i lost root, lost twrp, and the bootloader seemed to be locked again. No data or apps were deleted though. Then I updated to B150 same method.
any idea why root and recovery are gone? and how can I check if my bootloader indeed is relocked?
That is a completely regular behavior. You can check by booting to bootloader (holding up and power button when the phone is turned off), it will show you a white screen with the Android robot and info on bootloader and FRP status. To get everything back, just unlock the BL again, flash TWRP again and root again, no harm will be done, and your root software (e.g. Xposed) will start working again (although for xposed, you'll have only the client, the framework has to be flashed via TWRP once again).

unlocking again may result in factory reset.... or is there another method that keeps everything?

Unfrtunately yes, the phone will be reset. All you can do is to back it up and then restore it. Next time you update firmware, update it with "update.zip" from TWRP, this way, only recovery and root will be removed, but not the BL unlock.
look around, it is a workaround for skip factory reset in unlock/relock procedure.

i have a VNS-L21C185B360,
i unlocked the bootloader then flashed twrp then rooted my phone and it worked for a while,
i wanted to do a factory reset and after i did a factory reset i lost the root so i downloaded `UPDATE-SuperSU-v2.46.zip` and flashed it with TWRP then i get bootloop i went to TWRP and did wiped my phone, and still get bootloop,
so i downloaded `HUAWEI P9 Lite Firmware (VNS-L21, Android6.0, EMUI4.1.1, C185B150).zip` and tried the dload method but i get `software package incompatible`,
so i tried the b370 update `huawei-p9-lite-vns-l21-nougat-b370-update-emui5-dual-simeurope-stable` but still the same message,
i thought if i flashed the stock recovery from the b370 update i can do a factory reset and it might work,
so i want to fastboot but i get frp locked, i tried unlocking the phone again but i get `command not allowed` so i flashed it through twrp and now i cannot access the recovery,
so my current status is:
i have a locked bootloader which i can't unlock because i didn't enable the oem unlock in developer options,
i have no recovery,
i have a locked bootloader and a locked frp
i have eRecovery
i can flash stock roms through 3 buttons mode but every thing i tried so far give me incompatible software
is there is any way to fix my phone ?
i just tried flashing b160 i get it from here update*hicloud*com:8180/TDS/data/files/p3/s15/G1164/g104/v66034/f1/full/update.zip
still won't flash
I was testing messi2050's arm64 TWRP and LOS. i was using it a while, then decided to restore a old backup with arm64 twrp. restored fine, but i locked myself out when my pattern was unrecognized. I pulled battery and attempted to boot into twrp using hard key method. I was unable to do so, each time it would boot back to system. It seems that the white screen prompting to factory reset has dissapeared entirely. The volume keys work fine, so I don't think that's it. I've flashed stock with LG Bridge and LGUP. I've locked and unlocked bootloader. Interestingly, when i flashed stock with LGUP, it didn't factory reset or remove my apps.
Hi,
I Wanted to Install A Custom ROM Into My Oneplus 5 So I Flashed It Via TWRP Recovery And I Alslo Rooted My Phone To Do So, Then After A Few Days I Was Tired Of My Custom ROM And Wanted To Revert Back To The Orignal, So I Flashed My Orignal ROM To My Device And When I Tried To Relock The Bootloader Through Fastboot. Once Done, My device Refuses To Boot And Displays The Following Message: "Your Device Is Corrupt. It Can't Be Trusted And Will Not Boot".
Then I Got Very Scared And Unlocked The Bootloader Again + Wiped Everything (Including System) + Flashed TWRP Recovery + Flashed (Via TWRP Sideload) a Previous Version Of Oxygen OS And The Booted It Once Again Everything Went Fine And When I Tried Relocking The Bootloader The Device Once Again Started To Show The Same Message Again !!
I Have Lost Every Single Hope Of Recovering My Device Except You Guys.
Any Thought On How I Can Resolve?
Thanks!

Why do you want to relock it? Life is better with Magisk and Blu_Spark in my opinion.
If you want your bootloader to be locked I find it easiest to use the MSM tool (hard brick recovery). It'll wipe your phone but restore it to a like new out of the box condition, just choose a firmware.
Cheers!?

How about you try the MSM Tool to start again from scratch.

Using the miflash tool I flashed stock firmware (some version of android 8) after previously having a custom ROM installed. Everything worked fine until I rebooted after updating to the latest version using OTA.
My phone never got past the android one screen where it would freeze part way through, and after removing my sim card I could get to the pin unlock screen before the lock screen but after inputting the correct pin it would reboot and ask me for it again and again. I can get into fastboot fine but since usb debugging wasn't enabled and my bootloader is locked I can't reflash.
Booting into recovery also only brings me to a screen where the android mascot has a red triangle with an exclamation mark and a message saying "No command", so I can't factory reset.
Is there anything I can do to unlock the bootloader in this state or factory reset? (all flash tools and fastbooting into TWRP require the bootloader to be unlocked which in turn requires usb debugging to be activated)
Thanks for your time.
Update: I messed around with stuff on the cli based tissot tool and used option 2 to boot me into TWRP. It didn't do that but brought me into android where a system process kept repeatedly closing until a random factory reset happened.
I then got into normal android for a bit before I had to reboot (did remember to unlock the bootloader this time). I can now install twrp fine but every time I install the stock rom using miflash or try to install resurrection remix through twrp I get the same bootloop issue.
For some reason also my internal storage is completely empty no matter what i do so i need to sideload roms via sd card. And sometimes twrp gives me the error "failed to mount /system"
Trying the latest version of LineageOS next.
Update 2: if you have the same issue I had, the only working fix I've found is this restore point for twrp. Have not tried to update yet in case it breaks again but will make a final update with how that goes.
[SOLVED] Mi A1 BOOTLOOP
THIS PROBLEM IS VERY ANNOYING!! (The reason is because i didn't backup EFS before i flash Custom ROM) And I would like to share how to RESOLVE it. **your phone must be Unlocked Bootloader. Search Google how to do it. (Quick tip: in Fastboot...

Seems I found a way to semi brick my SM-T500. I was attempting to install the LOS 18.1 ROM just posted in the guide section. Some how I got the "can only install official" error message on my download screen after flashing TWRP. Made the mistake of flashing only the stock AP without BL or CSC and now I can't get into either recovery or download modes. Holding vol up and down and plugging in USB cable does nothing. Same with holding power button and either vol up or down. Blank screen. Can only power on and boot to system.
Did you install twrp and can you get into recovery. I had similar problem but was still able to get into download mode from power off. However to do so I had to boot into twrp and select reboot and power off... from that menu you can also boot directly to download mode... I know that doesnt halp much if you hadnt installed twrp yet... but thought I would throw that out there...

I can't boot TWRP or download. The only thing that will boot is system. Can't even get to the lock/unlock screen.
can you connect to adb shell? and try #reboot download
or #reboot twrp. I figure if you get to download you can reflash stock and start over.
Also when your trying to boot into recovery try not being plugged in. Not sure about this device but a lot of older Samsung's that I had would not let me get into recovery if I was plugged in during boot.
Locked oem mode
Locked download mode
Locked wipe factory
Locked update from sd card
Recycling item...
Need factory reset
I saw alot of issues with twrp so I tried Magick for first time ever on my SM-T500 and had a minor hiccup bc I wasn't paying attention to firmware and installed an old AP with newer firmware but ended up just reflashing the whole tablet with the same firmware as the AP that is required for Root and presto it worked! AND HEY IM DEF A NEWBIE!

Yeah I've run into the same thing, I originally missed the step to run Magisk after I flashed the patched tar and rebooted into the System and it triggered the "Prenormal KG state" problems. Finally I managed to flash stock ROM back and got to exactly where you are now.
I was able to just flash the patched Magisk AP without CSC and BL, and now it will only go to stock recovery and was able to get TWRP to work once but couldn't factory reset or wipe cache due to (which I assume was) a ton of mounting failures when it loaded.
Anyone else have suggestions to get this thing stable so I can flash LOS? I can get to Download mode.
hello, I post this because it's seems the same subject. I have to password protected (forget password) original rom tablet (non root). For me the datas are not important , I just want to remove the password or reflash with original rom. I downloaded Odin , usb driver and correct firmware. I select AP firmware with Odin, I see the connexion (COM3 green) and it's stuck to "setup connexion".
My problem is that it's impossible to enter in download mode.
When I try to shutdown the tablet, it ask me for a password.
When I press for seconds the power button , after few second I see the Samsung Logo and the tablet restarts.
I try to press volume up, volume up and volume down etc...but each combinaison...no recover, no download mode, nothing and impossible to flash . is it normal ? how to do to unsticked SetupConnetion ?
regards
bruno

This is not the same as my problem. My problem is that I flashed AP without BL and the two don't match. It isn't that things are locked but that I can't boot to anything but system. Can't boot recovery or download so I can't flash ANYTHING. Not even stock.
