hi friends,
i bought a blackview bv6000s.
It came with android 7.0 nougat.
I wanted to downgrade to 6.0 Marshmallow..
I know that the same gsm was sold with this OS ( marshmallow ) for a while.
So i ran my SP Flash Tool and flashed an official rom found on the blackview website.
I took BV6000s_Blackview_20170930(for MT6737T).
I flashed everything ( even the preloader => it worked last time i did it ).
But when i switched on my phone after having reconnected the battery,
the screen didn't display anything except a black luminous light.
I think i have bricked my phone using an official ROM.
How is it possible?
Thank's a lot for your explainations.

It's ARB --Anti Rollback. Several OEMs use this. Sometimes there are ways around it, sometimes not.
I don't know about this brand specifically, but Motorola prevents you from downgrading firmware unless your bootloader is already unlocked AND you leave gpt.bin off when flashing the earlier firmware. You will brick your phone if you try to install ANY earlier Motorola firmware without those conditions.

it's not due to ARB. i've followed these instructions with the same type of phone:
How to find current rollback index
_ Reboot to fastboot mode
_ Enter the following command: fastboot getvar anti
_ If the output is blank, then anti-rollback has not yet been enabled. If you get a number in the output, then that’s your current rollback index.
and my terminal retuned:
PHP:
$ adb devices
List of devices attached
WKMJKVWG8POB6DKF device
$ adb reboot bootloader
$ fastboot getvar anti
anti:
finished. total time: 0.003s
so there is no rollback index.

i tried to upgrade also and it is the same. i don't know about gpt.bin ( it's not referenced by my scatter file - MTK ) but i've entered the "developer mode" and switched on "unlock oem".
your type of smartphone is not the same as mine.
thank's for your answer anyway.
Why the downgrade Nougat is so much better that marshmallow & Oreo?

No, I have Motorola and LG. But you were asking how it could have happened and I was saying many OEMs put measures into place to prevent downgrading to earlier firmware.

hi hiitsrudd,
Marshmallow is less consumer than nougat ( watt ) because it has a simpler interface.
that's why i want to downgrade.

thank's again ChazzMatt, but i can confirm via fastboot that my phone has not been bricked by ARB because there is no rollback index.
it was anyway a probable cause of my problem.
but if i can't neither upgrade from an official rom, i face a problem totally different.
i'll go to the blackview website too, then i'll go back to tell you how to fix this issue.

Hi all,
I've spent a rather frustrating week or so in the throes of searching Google and XDA to figure out how to get my brand new RS988 upgraded to the 21c software version on Nougat. Here's what I've done so far:
-Check for OTA updates using the OS. No dice...it went from 11a to 11c and will not find any further updates.
-Use LG Bridge to try to update the software. No dice. The software tries to get the current OS version and then says "cannot find operating system version" and won't contact home base to get the new files.
-Reboot into boot loader to install TWRP. No dice...the phone will not reboot into the boot loader for some reason. I've tried using both the ADB method of "adb reboot bootloader" and "adb reboot-bootloader", but both just have it reboot into the full OS. I've also tried powering on the phone while holding the volume down button, to no avail.
-All root and TWRP methods, and even getting the official bootloader unlock require booting into the boot loader
The one thing I *have* been able to get to work was re-flashing a KDZ of the RS98811c software from autoprime's linked repository.
As best as I can tell, I am stuck. Without being able to install TWRP via the boot loader I don't know how to update the software. Please help me figure this out!
Edit: additional device info added
Android version: 6.0.1, 2016-07-01 security patch

Thanks!
Use lg up
It's possible that you have the RS988.BPT version (Brightpoint), which only got updated to 11h, I believe. I sent in a RS988.USA version, and they swapped for a new BPT motherboard. I've since sent it back yet again to get that resolved.
It appears to be a Tracfone Wireless version, according to the box, at least. It was supposed to be new, not refurb, so fingers crossed that's all good as well. Even if it was the Brightpoint version, wouldn't that have been fixed when I flashed the USA stock ROM?
I also don't see how to use LG UP to reboot into boot loader mode. It only shows me the phone, with nothing clickable, and a selection of 4 processes: refurbish, upgrade, phonesetting, and FOTA upgrade. Not wanting to mess up my phone, I am trying to be cautious about just trying either of the latter two options. Especially without a file there. Thoughts?
You did unlock the bootloader am I correct?

Nope. I can't get into the bootloader (unless I've totally missed a method to do that). Even the instructions on LG's website pre-suppose that you can enter the bootloader. Step 9 on their bootloader unlock instructions say:
9. Enter your phone’s unique Device ID. You can view the Device ID by connecting your phone to the PC using a USB cable and entering "adb reboot bootloader" in DOS command window of the folder you created in previous step (for example: C:\tools). Your phone will reboot into the fastboot mode. Enter "fastboot oem device-id" in DOS command window.

Unfortunately, issuing that command simply reboots the phone without a bootloader in sight. Any commands issued by fastboot after the "adb reboot bootloader" command just sit there saying "waiting for device". I think if I could get this far, the excellent instructions elsewhere on these forums would have me sorted the rest of the way, since then I could use TWRP to flash a more recent OS version. Thus far, it's only LG UP which works, which also requires a .KDZ file, but I can't find one for any version > 11c.
One further edit - I re-read autoprime's instructions and was at least able to get the phone to boot into recovery mode. (I can't tell whether the grey or white highlight is the "active" selection, so I haven't tried selecting one since I'd rather not wipe my device unnecessarily.) But in that mode it won't connect to my Win10 machine for adb or fastboot to do anything. Still can't get it into fastboot mode using "adb reboot bootloader". What am I missing? Feel free to be super-basic, since it's probably something of that sort.

Simple answer is "You can't". I am in the same boat, stuck on 11c with no OTAs in sight. The ability to boot into the bootloader wasn't added until a later version (11h, I think?) So until/unless LG releases a KDZ of one of the later versions, you (and I) are out of luck.
Further futile time spent with LG revealed one more issue: the phone apparently was originally for Tracfone. (Never mind that I bought something specified as RS988.AUSATN and not as RS988.ATFNTN.) LG claims they have no say in the operating system or updates (even before they determined it was Tracfone) and now Tracfone says LG is solely responsible for the OS.
What is going on with these jokers?

Hey AdamDG, were you able to solve your issue? I am stuck with the same situation and asinine LG folks won't help me out because Total Wireless/Tracfone are supposed to take care of the matter. But the latter are not responsible for software updates because they are MVNOs and don't (need to) care.
Truly jokers, but more importantly, taking customers for a s(laughter) ride!
Hello friends of XDA, I have a big problem between hands, I have a MOTO Z and I had it in android 7.0 since last year the update to andorid 7.1.1 did not arrive and I felt that with android 7 the battery was consumed very quickly, so I tried to find the update to flash it and just about 3 days ago I found it, I proceeded to download it and flash it in fastboot and adb.
The thing is that a few months ago, browsing through my phone (I had already rotated it, and unlocked the bottloader, I decided to re-block the bootloader, and remove the root, which never worked at 100) I got into the developer options, and I saw an option that until then I didn't know about its "OEM Unlock"function, as it was turned on and deactivated because I thought it didn't work.
Returning to the update flashing I proceeded as usual, with the commands, I proceed to restart the device and show the image of the boot of motrola but then it shows me a message in red letters.
"Startup Failed"
"failed to pass validation, backup to fastboot.
I thought it was a compatibility problem with the downloaded version of 7.1.1 so again I decided to flash the stock rom 7.0 but when I finished and restart the same message appeared.
I started to investigate and it seems that the OEM blockade is responsible for not being able to install any Stock Rom, or anything, and now I have a nice brick with Moto mods and I can't use it.
I wanted to unlock OEM in fastboot but nothing. sends message from "ALLOW OEM UNLOCK IN SETTINGS"
There is way to unlock the OEM from pc or fastboot without needing to be unlocked from the android settings, as in my case it is impossible for me,
I'd be very grateful for your help friends, I know it's a bit tedious to read but it's the only phone I have and I feel weird without it on the street.:bueno::bueno::llorando:
I'm with same problem here!

Try to boot in Fastboot flash twrp and flash ressurection remix rom. It's great rom. Forget about locking. I had the same problem like you as I was trying to flash stock ROM and lock bootloader.
I gave up on this.

Well, when the root didn't work properly, I flashed the phone again and blocked the bootloader. Will I still be able to install TWPR or should I lose my phone?

What do you mean with "I blocked my bootloader"?
Twrp is easy to flash. Root is integrated in ressurection remix rom. And this rom is great. Just try to flash twrp in Fastboot and than ressurection remix with twrp.
Can you boot in Fastboot?
Do you remember what build of 7.1.1 you had on your device before downgrading to 7.0?
If so, I would suggest finding that firmware (the full stock firmware, not OTA updates) or newer if you can, and try to flash that. Since your bootloader is still likely from the 7.1.1 build, a locked bootloader will only permit files matching the same patch level (i.e. from the exact same stock ROM as that bootloader patch) to boot.
If not, then unfortunately there's not a lot we can do. You could wait for a newer firmware to get leaked, but as your device is unable to boot (due to failing the bootloader checks) and you cannot toggle OEM unlocking because you cannot boot, it's a nasty vicious circle that is difficult to get out of. You may have to consider sending your device for service and pay for an expensive motherboard replacement otherwise, since Motorola have a record of your device being unlocked. Your service centre experience may vary.
Only lock a bootloader after ensuring you've flashed all the stock firmware and it is all the same patch level as your bootloader. Hopefully you'll find newer firmware that you can repair with.

I solved it, I finally flashed the stock rom to my phone and it works.
Apparently my pc was not flashing the stock rom in adb, and the phone turned off when loading the software. I did it 3 times until I load correctly and start well.
if you have the same problem apparently then OEM Blocking is not responsible. You have to flash the most current rom or the one that you had by default when the brick happened to you, you flash it in a normal way with commands of adb and ready, I would have to come back to life.
download from firmware center MotoZ Griffin the most current rom stock at 7.1.1

Thanks for your help friend, I finally flashed it with a recent android 7.1.1 update. Apparently the OEM lockout was not the culprit, but it was an interrupted flash of android 7.1.1 at some point when loading the software to the phone, it would shut down on its own and not complete the installation, which showed me the mentioned message. I didn't realize that and thought it was the OEM blockade.
I finally did it on another pc and it worked. the phone came back to life.
I have one Moto Z2 Force (XT1789-05), bought from coolicool.com, I didn't know device came Unlocked Bootloader, Device rom had problem with many apps, I googled and found one topic in XDA developer to Install Stock Rom, I downloaded and Installed India Rom, it's worked somehow fine, but still had problem, I downloaded Verizon Rom, Android 8, after Installed Android 8 Verizon Rom, Locked device bootloader immediately, now device stuck at Welcome Wizard in Android 8, after select language I got this message: (Please wait, this may take a few minutes) this is proof video (http://ahmn.co/Upload/IMG_0161.MOV), after this issue, device already locked, I can't unlock, because need to go to the Developer Option in Setting, I stucked in Welcome Wizard, there isn't any bypass, So, I start to search in Google, XDA-Forum, Android Central and more, I created many threads, many requests, no one can't help me, I tried to reach google developer support to the tell to me how can I bypass Android 8 Welcome Wizard, there is must be a way, but I can't find it, now I can access to Android Recovery and Bootloader

You can find his post here explaining the process more in detail: https:// lgk20.com/root-lg-k40-lm-x420-bootloader-unlock-twrp/
MODEL #: LM-X420MM
Any help is appreciated,
Thanks in advance.
im having the same problem. i must have a proclivity towards phones with what seems impossible rooting methods. the first was the samsung j7 prime and now the lg k40 lmx420mm. ive gotten as for as adb reboot-bootloader, just restarts device, fastboot commands are either not recognized or i receive "waiting on device". Ive updated drivers, followed a diff. method found on reddit posted by jamesrascal (i cant post url here because of my newb status). Phone just stays stuck in firmware update. i feel as if ive exhausted all resources, any direction or help would be appreciated, im not educated on rooting ive been successful a few times on other phones and jailbroken some iphones, im mostly doing this to learn and teach myself so it isnt urgent but i need help to continue any further. thank you
Same problem for me. Because the device has good value for the money it would be nice someone can help us here.
Further this device seems to be full android treble conform I like to know how benefit from this circomstance.
I have LG K40 LM-X420EMW with dualsim.
Thanks for every hint!
@blanksus
IIRC an Android user can not unlock the bootloader without first OEM unlocking, because without this process the device will not accept the bootloader unlocking command.

OK, but it is not possible to get into fastboot mode to enable the OEM unlocking. I marked the slider in developer option butz still there is no chance to get in fastboot mode.
After command "adb reboot bootloader" the device always reboots in normal system mode.
@baerenbisch
Once you enabled the OEM unlock on your Android, the “unlock ability” flag is set to 1, which allows you to use the
Code:
fastboot flashing unlock
command what unlocks device's bootloader.
BTW: Once you have enabled OEM unlock, it stays on. Even if you do a factory reset, it stays unlocked until the setting is manually altered again by going into the Developer options section.

Hm,
may be it is "allowed" to unlock but in the "LG K40 (LM-X420EMW) real world" it is not possible.
You dont reach fastboot mode which could enable using the order you proposed.
Device reboots into standard mode instead of wanted fastboot mode after sending "adb reboot bootloader"
I think thats the problem.

I wrote a guide as part of my porting of postmarketOS to my K40.

Greetings all, I have come to ask for advice on how to debrick my lg v60 version V600TM20n. First, how I ended up in this situation.
To begin, I followed this guide to unlock bootloader and root my phone then I followed this guide in an attempt to install a custom rom however, i did not get too far.
I tried to remove vbmeta verity as per the requirements of the form and in doing so input this line into my bootloader fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img with the file provided by this form I think this is where the issue I have is comming from but moving on.
I then attempted to download lineage os following the guide but it did not work and I was fed up by this point to I began the process of reverting everything I did. I downloaded SuperSu to deroot my device. After derooting my device I went to the bootloader and typed in fastboot oem lock, locking my device and dooming me.
In my attempts to escape from the hell I am currently in I downloaded LGUP v1.16.03 and v1.14 (I tried them both deleting the previous one before installing the new one) yet each time I was stuck with the this error code Error Code = 0x2000, Invalid command response when the progress bar reach 9%.
The dll i used is version 0.0.3.23 and the one provided by LGUP v.1.16.03, and the firmware I attempted to download was V600TM20n_02_TMO_US_OP_0111.kdz on LGUP it says V600TM20n oh and also I did try UPPERCUT, no resuts
Currently on my phone's download mode screen at the bottom in red it says Modified / E / L / RO / id : 3(NA2_US) I have also tried LGUP Cmd but same results
I have tried LG bridge but it says connecting and then no device found :/
I wish i could say i tried lg flash tool but i have no idea on how to use it
Possibly another big mistake (idk what im doin) I used the QFIL and restore the abl_a and abl_b to their original versions after locking the bootloader.
Please tell me if there is anything else I can do or if I now own a $300 brick. If I do have a $300 brick is there any value I can get from it to fund my walmart flip phone that I will have to buy?

I wish i could say i tried lg flash tool but i have no idea on how to use it
Possibly another big mistake (idk what im doin) I used the QFIL and restore the abl_a and abl_b to their original versions after locking the bootloader.
Please tell me if there is anything else I can do or if I now own a $300 brick. If I do have a $300 brick is there any value I can get from it to fund my walmart flip phone that I will have to buy?

try
C:\ADB >fastboot devices
C:\ADB >fastboot OEM device-info
etc
replacing
C:\ADB with where ever you fastboot file is located
I too am having the same issue.
I recently wanted to try Android 12, I took a chinnese version of it and my phone is unusable, literally all chinnese.
I want to downgrade, I enabled Debugging and Oeam Unlock in Dev options but I get the ''remote: 'Flashing Unlock is not allowed"" when I try to fastboot oem unlock, I tried different USB ports, I keep updating all my drivers for ADB but nothing is working. I'm panicking a bit cause I don't have a phone to use, and not many people work with ONEPLUS in my country.
If someone has an answer, please save me lol

have you tried the code above ??
cant you just download the official original firmware and flash that ? im not familiar with the oneplus flashing techniques, ive always had samsungs except for the htc evo 3d back in the day
I tried them all, nothing seems to work
I'm stuck at 'Flashing unlock is not allowed'. I've set up everything I need to in Developer Options, I made sure they're all enabled.
It's really weird, could it potentially be a software issue? The software itself will not allow me to unlock OEM even though the check is turned on?

how does the one plus flash firmware ? for samsung we use a tool called odin, do you not have a similar tool for your device ?
I don't recall having any toolkit like that, but in order for the toolkit to work.. do you need to have an unlocked bootloader?
Cause the main issue is that I can't unlock it.
i dont think so, if your flashing an official firmware, but for your device i cant be sure of that
?
did you try running your commands as an su , is your device rooted ? you could try sideloading an update.zip maybe
what does it say when you flash this command ? true, true false ?
C:\ADB>fastboot OEM device-info
maybe this will help https://forum.xda-developers.com/t/...us-2-back-to-stock-100.3269543/#post-64279667

OK try
c:\adb
Adb fastboot oem device-info
Replacing
C:\adb
With where ever your fastboot is located
Just to check if your device is showing is oem locked or unlocked, it will display with a true or false option. I can't really advise to much as I don't have experience with that device
You could also try
fastboot oem unlock_critical
Not sure if that will work for your device though
Idk what else to recommend, are you stuck at boot ? Can u boot into recovery mode ? Do u have an ext sd card slot

Have youlooked at that
if you can confirm your phone has a mtk chipset use mtkclient to bootloader unlock it https://github.com/bkerler/mtkclient
otherwise youre out of luck

im not stuck at boot, i want to flash gsi but it says device is in locked state even with oem unlocked in dev options, adb debugging enabled etc , and just wont let me flash.. its starts flashing and then fails due to locked state

If the flashing starts, and fails, the os would be overwritten and you wouldn't be able to boot. So what you mean is the process trys to start but fails, right yh then I don't know what else I can say to try and help, let's hope mtkclient is an avenue you can pursue
