No fastboot mode alcatel a5 5085 LED

Good afternoon
My device is the alcatel a5 LED (5085y) which has the MT6753 chip and is running android 6.0 and is network unlocked. I have been trying to unlock my bootloader and have tried the usual way of booting into fastboot but when i attempt "adb reboot bootloader" it reboots the phone back to the normal mode.
I have a little understanding of other android devices but i am fairly new to mediatek devices so my question is do they have a fastboot/bootloader mode and if they do is there any other step i need to do besides setting the allow oem unlock setting in the developer options?
I am trying to unlock the bootloader so i can then try to port twrp and then root my device and the only available online guides all require using fastboot so am at a loss
thank you in advance for any information/help
Is no one able to shed a little light on my problem. I have recently acquired the auth file for my device and scatter file to use with sp flash tool which would I be right in it being able to flash a custom recovery without unlocking the bootloader
wow i cant believe how helpful (sarcasm) the forums have become in my 10 years of being a member, i am more than certain that someone can shed a little light on my issue.

Unfortunately i have had no look as of yet, I know that it should be possible using flashtool to flash a custom recovery, as it has a secure boot/locked bootloader it will require a special DA.BIN file (downloader file for flashtool), i have extracted all the files from the official firmware recovery software and obtained some DA.BIN files but i think that they are wrote some sort of protection to stop them being used in spflashtool, this is something im looking into and if i gain any progress i will write here

System has been destroy + Usb debugging OFF + Bootloader Locked

Hi community
First Thanks to the people who take time to help, and admin that create that forum. Im always glad to see that s there is still people caring about helping each other
I come to you cause I spent the last 2 days trying to fix my brand new phone.
Brand : Xiaomi
Model : Mi ultra
My Computer : MacBook Air
Problem : "The system has been destroy"
Other problem :
- USB debugging OFF (not able to access to the phone in any way)
- Bootloader Locked
How its happen :
After installing an EU Rom, I re locked the boot loader using Adb... And it crashed.
I tried almost everything you find on internet using a Mac and till now nothing worked.
I tried to unlock the boot loader using ADB, which one the only thing who seems to be working and I got an error message saying that the Miunlocktools was too old ... ?
The token was available, as I already unlock it.
Does anyone know how I can switch ON the debugging mode without accessing my phone, or Unlock the boot loader using my Mac.
It seems there is solution possible but using windows computer, and tbh I will not buy a computer just for that.. for the moment
Thanks in advance to everyone
PS : I will offer 50USD straight in BTC to the one who will provide me the solution that will help me to fix it
Locking / unlocking a phone's bootloader is done by means of Fastboot, not ADB.
ADB & Fastboot are 2 completely different things. Don't confuse them.
AFAIK you can't enable ADB ( USB debugging ) from outside, this can only get enabled from inside ( Android Settings -> Developer options ) unless one creates/provides a flashable, properly signed ZIP that contains the code ( read: update-binary script ) to rewrite device's build.prop file entries accordingly.
BTW: A locked bootloader always tries to run device's Stock ROM.
Thanks for your quick answer. In other word, is it possible ? I am looking for what you say.
If I rewrite it, will I be able to switch it ON then ?
Im not at all a professional , that's my first step in this "world". It seems difficult, I will need to read a lot I think
What do you think about the EDL cable also, do you think it can work ?

IDK.
Never have bricked a phone. And I never owned a Xiaomi device.
locking a bootloader (at least in xiaomi phones )results in the phone being reformatted and the stock rom is installed
also try installing the newest version of miunlock https://en.miui.com/unlock/download_en.html
you might have to wait 7 days or less or more or might not have to

Hi
I re locked the boot loader myself so I unlocked it before
Thats the version I have but in the terminal I got a message saying version is too old...

How To Guide WARNING: Read BEFORE Locking Bootloader

DO NOT LOCK THE BOOTLOADER WHILE ROOTED!
When locking the bootloader while rooted, the boot image will fail verification and the system will fail to boot. You cannot flash a stock boot image with a locked bootloader.
Locking the bootloader will not fix most issues. It will allow you to use apps that check for an unlocked bootloader without the need for any additional modification. That is the ONLY benefit.
If you still want to lock your bootloader, make sure you can say yes to each of the following:
1. Have you restored the stock boot.img / vendor_boot.img and the phone functions normally?
Spoiler: Restore Stock Boot
Boot / DTBO Images [Root / Stock] - 5 / Pro / Ultimate (NOT S)
These images are NOT built from source. These are the stock images from the firmware provided by Asus that are extracted with payload dumper and uploaded without modification. 18.0840.2202.231 18.0840.2201.226 18.0840.2112.211...
forum.xda-developers.com
Follow the instructions in the thread above.
Use only the boot and vendor_boot images.
Do NOT flash any images that end with "-magisk.img"
2. Have you made a backup of everything you do not want to lose when wiping the phone?
Spoiler: Make a Backup
The sdcard is part of the internal storage and is cleared by a factory reset
Copy everything you want to keep to a computer or USB-C storage device
Apps and settings can be backed up by enabling the Google Backup option

Reserved for QA information
I don't want to spread false information here, but here is a question post I created recently with two replies showing me contacting the help center (two different agents) confirming that I can use the app more than once to unlock the device's bootloader: https://forum.xda-developers.com/t/...nlock-relock-for-asus-rog-phone-5-5s.4367047/ . @Andrologic also confirms the case there for global (EU) version. I have a feeling that for the Tencent version it is because the sellers lock it on a wrong official ROM, or wrong ROM in general, e.g. global ROM, and therefore it confuses the unlock app. I am surprised the device did not even get hard bricked from locking on not the original ROM. By the way, I have contacted the help center of the US store, but I have a feeling it should work on the global (EU) version as well.

Based on new information, it does seem possible to repair the issues caused by converting.
That said, this guide is still quite relevant. After all, most of the issues people were having were caused by unlocking the bootloader, converting, rooting, and locking the bootloader. The warning for possibility of not being able to unlock have been removed, but the info about restoring to stock before locking has been left.
I send mine in for a motherboard repair I was rooted and everything I unrooted installed stock firmware and locked the bootloader again once I got the phone back I unlocked the bootloader once again and I am rooted again

@chairman011 what variant of the phone it is (e.g. CN or WW or US, ...etc.)? Also, when they returned it to you and you were able to unlock it again, was it on the original firmware (or any version in its lineage (i.e. not a ROM that's not original))?
If by using ASUS unlock utility one was able to oneself unlock the boot-loader once, then is it safe to say that (after relocking it) it'd be possible to unlock it again?

Some people have reported that you can't unlock the bootloader again after relocking, using the official "Unlock Device App", but I suspect it is an OS mismatch. This issue has only been observed on Tencent (CN) version with global ROM. Have anyone been able to unlock->relock->unlock on the same version of the phone, but not relocking while on the global ROM (i.e. relocking while on stock CN ROM)?
I am surprised the phone did not hard brick. Usually, and this is a general case in almost all Android phones with bootloader unlock capability, when you relock on a different ROM your phone hard bricks. Always restore to original ROM before relocking. Can people with Tencent (CN) phones with global ROM and locked bootloader flash the original CN ROM without unlocking the bootloader? If so, can you test the "Unlock Device App" to see if it works while on the CN (official) ROM? I gotta a feeling it might work in that situation.

It's an identification mismatch. It's similar to when you throw your SIM card in a different phone and your carrier lists you as having a different phone. Based on the information that has been discovered, it would appear that CN to WW conversions were wiping out the stuff that makes your device your device.

So, basically the bootloader unlock for tencent devices will always locked unless asus uodate their unlock app or has their been another way around it yet?
The unlock app should unlock the bootloader at least once. Unlocking it a second time has mixed results.
Hi there, can you guys help me? I'm one of those unlucky ones who got my phone corrupted and won't boot anymore due to the boot loader. is there a way to fix this?? I've got an ROG phone 5s 16/512 on android12.
Hope you guys can help me! I know you guys have amazing brain cells than me when it comes to these things lol
Oh! and my rog is not the china version thanks

TYou should be able to RAW flash yourself out of it if a factory reset doesn't work. This does happen when re-locking the WW.

Below post from the help guide (credits to the contributors) has links to RAW firmware packages. You just need any one of the WW packages. Download it and with your device in bootloader mode, run one of the .bat flash scripts that you'll find in the RAW package. The version doesn't matter, you can simply update to the latest firmware once you're back up.

Hi there, I did follow and did the raw setup it did got me through the boot loop. However, its stuck on the system start up updating screen and stays in 0%.
Darn i thought im already dead! i didn't even know how i fixed it hahahaha! but its working now successfully downgraded to android 11 because its the only firmware i found and managed to make it work again combination of alot of research in google and here xda. working 100% imei two of them, finger print and sn are all intact. thanks guys
For these few reasons I have to give up root & lock the boot-loader: 1. Financial apps stop working from time to time causing much grief; 2. I've used root functionality precisely for nothing for a year I've had it; 3. It was getting all too complicated to keep up with it all.
(The original intention for unlocking/rooting was to get some sort of unofficial VoLTE and VoWiFi for the mobile operator of my choice; however, it didn't help. Then a newer firmware implemented VoLTE and VoWiFi! So my impatience, admittedly couldn't be known at that point in time, backfired.)
I've nothing to preserve on the phone, due to having a Moto G 5G backup phone. I only had it working with adb & fastboot in my Linux laptop (up to date Fedora 36). I had no working Windows laptop then. But I do now. However, adb on Windows says the device is "unauthorised" (as expected); fastboot in it doesn't list the device. So I might be limited to my Linux laptop only. The phone was previously working on the last A11 WW firmware fine.
I've tried to follow the steps from the original post of this thread. First one worked with vendor_boot, dtbo & boot images (used only 18.0840.2202.231 versions of them). Second N/A. With third step, flash_raw_and_wipe_data.sh fails by core dumping.
Right now, the phone boots to fastbootd & not further. Any help is much appreciated.
(I think I'm inching towards fully bricking this phone. I'm not there yet, but getting closer . It'd be nice to get it working again without root & with locked boot loader. Any help is much appreciated.)
This is where I'm at while executing step 3 of the initial guide in this post:
When powered on, in the usual boot loader unlocked warning page, it prompts for power key to be pressed to continue.
(Here if power switch is not pressed within 30 odd seconds, phone powers down automatically.)
Once power key is pressed, it lands in boot loader. Selecting Start, it goes back to boot loader. I think this is called a boot loop.
While in boot loader, selecting "Recovery mode", it progresses to "Android Recovery". Here selecting "Enter fastboot" appears to take it furthest in the booting process of landing at "Android Fastboot".
(The version info showed in Fastboot -- 18.0840.2202.231-0 -- matches with the last A11 update I downloaded from Asus website & had it installed late March this year.)
I don't think it can boot any further at the state that it's in now.
I think this is where it needs a raw firmware to be flashed. This step keeps core-dumping in my Linux laptop when trying to use WW_ZS673KS_18.0840.2106.83_M3.13.24.40-ASUS_1.1.92_Phone-user.raw file that was linked in the original post. This version appears to be quite old. Could the version mismatch between what the phone was running recently (18.0840.2202.231) and the raw file (18.0840.2106.83) cause the core-dump issue? IOW, would somebody have a link for 18.0840.2202.231 raw file please?
I couldn't use my work Windows laptop due to an issue I cannot overcome (installation of driver needed for the phone is somehow blocked in it). So, soon I'll try it from a personal Windows laptop of my neighbor. Let's see if it can progress any further with the help of Windows platform.
In the meantime, I can appreciate to be informed about any tips and tricks such as if this is something that the phone cannot be recovered from. Or even somebody highly skilled would like to help me to achieve a fully functional phone (with bootloader locked please) for a fair compensation. Please let me know. Thanks for any guidance.

Confirm that you can send fastboot commands to the device. It's a prerequisite for flashing the original boot img back or doing a RAW flash if boot looped. That's the very first step you need sorted and confirmed. Sounds like you may not be in the right Fastboot mode. The RAW version doesn't matter too much as long as it's in line with your device version, you just need it to get back up and can upgrade normally to other versions.

You can use the patched odin to flash any A12 FW with a matching binary, but it won't affect your ability to unlock the bootloader. The most likely option is to use the EDL method by pulling the back encasing from your phone and using a paperclip or pair of tweezers to short the EDL pin while plugging into your PC. EDL is kind of a secondary bootloader that will allow you to run a variety of functions. Since the A12 is a MediaTek processor, I've tried using the MTKClient exploit through EDL mode to force unlock the bootloader, but so far I haven't seemed to get it working.

As far as everything I've tested so far...
Attempted to downgrade A11 to A10 (can't do it because of incompatible FW binaries)
Flashed several different model FWs & various other CSCs... the model I'm using is SM-A125U (AT&T). Currently the FW running on it is for SM-A125U1 (the carrier unlocked model) but of course still no "OEM Unlock" option in dev settings.
After I tried a few dozen builds I looked into EDL/BROM flashing, since EDL works as a ground zero primary boot interface and seems to work as a recovery/fastboot hybrud allowing both flashing & a CMD interface vs a separated Samsung "Download Mode" and Fastboot mode.
I haven't really spent much time scouring the web for different exploits (that aren't paid services) but I did come across "MTKClient" (https://github.com/bkerler/mtkclient), which I was able to successfully run. I tried using the "unlock bootloader" command, at which point it was a "success" and resulted in the device obviously being wiped, but after the following boot there still was no "OEM Unlock" option in the dev menu. Afterwards I tried flashing a custom boot.img built with Magisk, but even using EDL mode to flash, the device wouldn't boot and just gave the basic "this isn't an approved FW" error, so I had to flash the original boot back.

You can't downgrade from Android 11 to 10, because Android 10 has a lower SW_REV value. OEM unlocking shouldn't matter if you can force the PBL to be unlocked by a exploit. You can play with date and time settings in the OS and OEM unlocking may come back, as explained here:

You can try editing fimware files if you can't find a exploit for downgradeing SW_REV, or you can try from booting in to PRELOADER and with SP_FLASH_TOOL flash Android 10 scattar fimware. This phone is very new so it may be more difficult for finding exploits, you can play with crossflashing fimware and PRELOADER mode. Another thing is that EDL mode is only for snapdragon chipsets.
And try disabeling thoes security locks:
MTK "secure" boot -use mtksecbypass to disable
"Secure" downloads - try MTKClient

You can try editing fimware files if you can't find a exploit for downgradeing SW_REV, or you can try from booting in to PRELOADER and with SP_FLASH_TOOL flash Android 10 scattar fimware. This phone is very new so it may be more difficult for finding exploits, you can play with crossflashing fimware and PRELOADER mode. Another thing is that EDL mode is only for snapdragon chipsets.

I just tried flashing twrp lol, obviously didn't work. So with the a125, it runs on a mediatek processor (MT6765) which has the EDL mode if you short the internal pin. I've tested a couple different exploits which "unlock" it, but after flashing anything custom it always boots with "you can't have custom...". So right now I'm just going around in circles
Edit: Right now I'm playing around with Miracle Box to see what all I can accomplish. I'll update if anything new comes along.

Ok, good luck with Miracle Box, hope you got the one that isn't backdoored...
EDL mode should be only for Snapdragon, mediatek has it's own PRELOADER mode, as I know of it. Some phones have META-MODE. Could be miscommunication bettwen us.

Yeah, I've pretty much gone around and around in circles with this. The thing that makes it curious though is after running adb shell getprop and looking through the build, I noticed most of the properties relating to oem unlocking were actually set to allow, the one outlier was sys.oem_unlock_allowed. Which kinda pushes me back towards the KG/RMM. Athough, I'm not sure if that's because I have the unlocked U1 FW flashed (it's actually an a125u), or if its the same on both. Either way, running an MTK exploit to unlock the bootloader (which I've done) doesn't actually contribute anything to whether or not OEM Unlocking is visible in dev settings, which is the primary prereq for unlocking the bootloader.
I did consider trying to update the sys.oem within build.prop in /system, but obviously without a root it's impossible, which lead me to possibly unpacking the stock FW super.img and trying to pre-edit the build within so I could re-pack and flash using the MTK Bypass exploit, but those necessary oem properties aren't even listed on either of the build files I did manage to find.
So as of now I've got one more test I'm going to try before I give up. All things considered, the most likely issue is the KG/RMM state, so I'm going to test a few different methods to try and circumnavigate those and possibly unlock the missing OEM Unlock option.
I can at least say that it's likely not an issue of manufacturer locked loaders, considering that's primarily a snapdragon issue, whereas the A12 runs on MediaTek, so fingers crossed.

If you were able to see the settings are enabled through ADB that is the same as it showing in settings. KG/RMM state could also be the factor of why it isn't beeing shown as of what you have said. Samsung has came a long way with these dumb knox securities which just makes everything worse, you might be able to find a clue for this within their KNOX documents ( I sent a link in a post above). Maybe you can find a profesional, a person that has worked for samsung and can maybe help you with this. It just gets too complicated at one point. If you have telegram or something were we can talk further about this it would be nice because some exploits and stuff if you mention can violate xda rules... So I don't know what else to tell you, I never really was in a situation where I was required to do these type of stuff, only if I had to because of some problems I had. Maybe you can find answers for all of this on some really old forums where people use to do everything to brake apart samsungs and mediateks security locks but still dout it.
For now, hope you learned something and dm me if you want to chat on telegram or etc about this. Don't think something is impossible because you can't find a answer for it, everything is possible.

Well after trial and error, I finally got it. I had to hunt down an Android 10 firmware with a matching binary to allow a downgrade, and after a couple of tries, using the auto-date/time method, OEM unlocking finally decided to show itself in dev settings. Specifically, I used this FW, flashed with Odin https://samfw.com/firmware/SM-A125U/USC/A125USQS2AUF3

Well, you couldev done that allready out of the start. But even do you got OEM_UNLOCKING shown doesn't really mean anything on U model, unless you have exploits and methods for unlocking PBL. Which as said wasn't very sucessful at all for you. I recomend to you that you check our DMs. mtkclient has some bugs which are on the way to be fixed.
I've been working with mtkclient for months, before it even unlocked bootloaders, I was the first to unlock the stylo 6 bootloader and I had a bit of a hand in working out some of the bugs with the tool, I'm doing a full backup of the A125U model right now with mtkclient and after it's done I plan to try the unlock without having oem unlock option in dev options, but first I'll check to see what binary version I'm on, not sure if it's on android 10 or 11 right now. But I will sheet the backup
I finally finished my tutorial for the stylo 6 bootloader unlock and root so now I'm working with the A125U. I'm on 2nd binary and i think i got the bootloader unlocked, but if I flash the patched boot.img it won't boot. I'm gonna try a few ideas i have, so far no luck but I'm not gonna give up, I may crossflash, but I'm trying to find the easiest way to do this.

Question OEM Unlock missing on SM-A326U

Hi guys,
Man oh man this phone...
So basically I'm trying to unlock my bootloader without waiting the 7 days, since I simply don't trust this phone to give me the OEM Unlock option after 7 days...
Before I decided to unlock my bootloader I had been using this phone for about 2 months like normal, sure I uninstalled a ton of bloatware and system apps that I didn't need which MIGHT have been the reason it didn't show the OEM Unlock after months, but the battery life was amazing.
But recently I've been considering rooting my phone, and before I started factory resetting and trying many different things to show the OEM Unlock option, keep in mind I've bee using this phone normally for a couple months, I checked the developer options and not a surprise, OEM Unlock wasn't there.
So ever since, I've tried sooo many things to show the OEM Unlock:
( I reflashed the stock firmware with Odin in between all these methods I've tried )
Also before I list everything I've tried heres the full specs of this phone and the drivers I've installed on my Windows 10
Samsung Galaxy A32 5G (SM-A326U)
T-Mobile, MTK, Network locked, No SIM, NOT Snapdragon
Drivers I've installed on my PC: Google USB Driver, ADB Interface, Samsung Android USB Driver, MTK Driver, USBDk and a few more can't remember the names...
1. Changing date, checking for an update and changing the date back, tried restarting the phone in between, tried turning wifi on and off in between.
2. Combination firmware, got unauthorized error on the download mode screen talking about the pit file.
3. Tried running:
adb reboot bootloader
fastboot devices (It successfully recognized my phone)
fastboot oem unlock: Unknown command
Didn't even run the command...
4. Since its a MTK CPU I had hope for mtkclient https://github.com/bkerler/mtkclient
It just kept asking to connect my phone, tried connecting with recovery mode, download mode and fastboot mode, none of them were recognized
The reason I need a quick way to unlock the bootloader, is cause I will be doing stuff with this phone that might result in me having to reflash the firmware which I can't risk it relocking and have to wait 7 days each time something goes wrong.
I heard that T-Mobile phones bootloader's are impossible to unlock, someone please tell me that is not true...
So basically,
Is there any way to unlock the bootloader? If not why and if yeah, what have I been doing wrong and how?
Thanks guys
7 days what? Tmo A326U doesnt have the option to unlock the bootloader, you need to pay the people here that provide the service. They are the only ones that seemingly know how to get it unlocked, and I can vouch for it.
Seriously... So there's no way to unlock for free, or by waiting...?
Not a bootloader unlock. Its not just Tmo that are locking these down tighter.
You can unlock it for free if you can figure out whatever they do ;-)
Nah idc about a network unlock since I don't have service for this phone, I just wanna know if its possible to unlock the bootloader... I've tried everything

You said not a "bootloader unlock" so I was assuming you're talking about network unlock... Sorry, but should I just give up, there's seemingly NO WAYY to unlock the bootloader of a T-Sh*t phone.
Oh just misunderstanding my bad. I meant you cant wait for a bootloader unlock, but you can wait and maybe they would carrier unlock it later... but thats not what you want anyways.

That's kinda sad, I think I'm gonna just give up, but thanks for the information... Hopefully something happens in the future that allows it to be unlocked soon... Thanks man
I doubt they'll bring it back. OEM unlock that is. My phone is over 7 days old and I did the factory reset by holding the volume down and power buttons and then the volume up and power button and did the full factory reset. OEM unlock is still gone. Yes I got the developer options turned on. I rooted a couple of Nexus 6p's which of course are obsolete now since they were 3G and there is no backward capability. At least I got them used, replaced the batteries myself and can use them as WiFi phones with Talkatone through my WiFi. Read some blurbs about Kingo root working but I'd like to see that someone has pulled it off with the A32. Am under a 2 year obligation but I bought a second one to experiment on. I did that before I found out there was no OEM unlock. Well, if I break one, I'll have a backup. Except the phone is tied to the SIMM and I'd have to bring the backup in to have it reprogrammed.

There was a similar procedure to unlock bootloader on a samsung mtk (A125U) same carrier as yours (T-Mobile TMB and the same applies to MetroPCS TMB) basicaly, you had to flash BL files from the A125W (canadian version) then unlocking bootloader using testpoint (bootrom mode) then using any paid or free app (in my case i use a paid one because i run a repair shop). even if you unlock bootloader using paid tools, it gets locked again when it turns on. (i tested it without flashing BL files)
sadly, i dont have a A326U lying arround to test said procedure.

Locking/Unlocking the Bootloader​bookmark_border
On this page
Unlocking the bootloader
Locking the bootloader
Setting lock/unlock properties
Protecting critical sections
By default, most Android devices ship with a locked bootloader, meaning that users can't flash the bootloader or device partitions. If needed, you (and device users with Developer options enabled) can unlock the bootloader to flash new images.
Unlocking the bootloader​To unlock the bootloader and enable partitions to be reflashed, run the fastboot flashing unlock command on the device. After setting, the unlock mode persists across reboots.
Devices should deny the fastboot flashing unlock command unless the get_unlock_ability is set to 1. If set to 0, the user needs to boot to the home screen, open the Settings > System > Developer options menu and enable the OEM unlocking option (which sets the get_unlock_ability to 1). After setting, this mode persists across reboots and factory data resets.
When the fastboot flashing unlock command is sent, the device should prompt users to warn them that they might encounter problems with unofficial images. After the user acknowledges the warning, the device should perform a factory data reset to prevent unauthorized data access. The bootloader should reset the device even if it can't reformat it properly. Only after a reset can the persistent flag be set so that the device can be reflashed.
All RAM not already overwritten should be reset during the fastboot flashing unlock process. This measure prevents attacks that read leftover RAM contents from the previous boot. Similarly, unlocked devices should clear RAM at every boot (unless this creates an unacceptable delay), but should leave the region used for the kernel's ramoops.
Locking the bootloader​To lock the bootloader and reset the device, run the fastboot flashing lock command on the device. Devices intended for retail should be shipped in the locked state (with get_unlock_ability returning 0) to ensure that attackers can't compromise the device by installing a new system or boot image.
Setting lock/unlock properties​The ro.oem_unlock_supported property should be set at build time based on whether the device supports flashing unlock.
If the device supports flashing unlock, set ro.oem_unlock_supported to 1.
If the device doesn't support flashing unlock, set ro.oem_unlock_supported to 0.
If the device supports flashing unlock, then the bootloader should indicate the lock status by setting the kernel command line variable androidboot.flash.locked to 1 if locked or to 0 if unlocked. This variable must be set in bootconfig instead of in the kernel command line in Android 12.
For devices that support dm-verity, use ro.boot.verifiedbootstate to set the value of ro.boot.flash.locked to 0; this unlocks the bootloader if the verified boot state is orange.
I have the A32 5G (64Gb Int. Stg.) & it's the Tracfone Only version or SM-S326DL. After recently receiving word that Android 13 was awaiting us, I quickly allowed my device to receive this very kool OTA operating system update. I mention this, because a week earlier I received an email from my prepaid wireless provider instructing me in detail how to manually unlock my A32 5G handset. So, to be clear, Tracfone notified me in their email how to unlock my device, but whan
this happens to often, to write this off as an app-mishap xda...why?!
(pls. explain this to me, what is really going on)?
