Downgrade 7 -> 6 FAILED Do not allow to flash Bootloader image on Unlock device

edit: DO NOT DOWNGRADE THE STOCK ROM IF THE BOOTLOADER IS UNLOCKED.
Started with an unlocked and unmodified and unrooted Android 7 Stock ROM. Wanted to downgrade to Android 6 Stock Rom for Xposed. I used this guide. I get the error "FAILED (remote: Do not allow to flash Bootloader image on Unlock device)" after typing flashall.bat . How it is possible to downgrade with the unlocked stock bootloader?

Click to expand...
Click to collapse
It fails at flashing fastboot, but it looks to have stopped without progressing further? Try making a separate BAT file and adding:
Note: I haven't tested this for downgrading, only for resetting.
Code:
fastboot flash partition gpt_both0.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash dsp adspso.bin
fastboot flash system systemchunk0.img
fastboot flash system systemchunk1.img
fastboot flash system systemchunk2.img
fastboot flash system systemchunk3.img
fastboot flash system systemchunk4.img
fastboot flash system systemchunk5.img
fastboot flash system systemchunk6.img
fastboot flash system systemchunk7.img
fastboot flash system systemchunk8.img
fastboot flash system systemchunk9.img
fastboot flash system systemchunk10.img
fastboot flash system systemchunk11.img
fastboot flash system systemchunk12.img
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
pause
Then run the BAT file. Lenovo themselves have likely disabled fastboot flashing and re-locking.

At the moment I can not recommend to downgrade an unlocked P2 with Android 7. Found your Post and created a Batch file. It failes in createing and ereasing some steps. But the phone is starting with Android 6, now. I'll investigate the modem functions within the next days and post the results. Maybe QPST-Images are required for correct downgrading.

I have soft brick my modem after I erased the modem partitions.
Since you can't flash NON-HLOS.bin after unlocking the bootloader, it's dangerous to downgrade.
But I can confirm (I did it many times before unlocking the bootloader and after) that you can downgrade for 7 to 6. The system is working fine and you can still install the OTA.
If you find a solution for the modem part, please post the solution

Thanks but I already did that.
After doing it, the sim card was successfully detected but after a few second the signal is lost (like I'm in a no signal zone) and I can't connect to my operator's access point.
I maybe have a wrong baseband driver or something like that, I'm not sure.

At the moment I can not recommend to downgrade an unlocked P2 with Android 7. Found your Post and created a Batch file. It failes in createing and ereasing some steps. But the phone is starting with Android 6, now. I'll investigate the modem functions within the next days and post the results. Maybe QPST-Images are required for correct downgrading.

I have soft brick my modem after I erased the modem partitions.
Since you can't flash NON-HLOS.bin after unlocking the bootloader, it's dangerous to downgrade.
But I can confirm (I did it many times before unlocking the bootloader and after) that you can downgrade for 7 to 6. The system is working fine and you can still install the OTA.
If you find a solution for the modem part, please post the solution

hi !
can you please confirm that before flashing your phone was bootloader unlocked or locked ! and how you sure that the soft bricking of your modem occured only for erasing the modem partitions ? do you think, it's completely safe to downgrade from stock nougat to stock marshmallow for an locked bootloader ??

@mishua0 If the bootloader is locked your your warranty is not void. It is as risky as doing an upgrade from marshmallow to nougat.
@[email protected] please stop spamming the P2-Forum with your modem issue. You created already a thread + posted the problem in other threads, too. As you see bootloader and modem partition are somehow write protected in the stock recovery. Lenovo might had a reason to lock it. QPST-Factory-Images for Recovery are not available at the moment. Example Lenovo K910
I can confirm after downgrading an unlocked but not modified and not rooted Stock P2 with the instructions from Post #2 that the modem is NOT working. This is not supprising as the modem partion is write protected for unlocked bootloaders and contains the updated Nougat code. But I could NOT fix it through an update from Android 6 back to Android 7. The modem is still not working. No SIM Card is recognized. I did a factory reset but that didn't help.

@Kontex : I didn't created any thread and linked my problem to barely two thread at this time. It's hardly spam. But it would be nice to create a thread for this specific problem.
By the way, have you tried to format the modem partition ? see -> https://forum.xda-developers.com/showpost.php?p=71966113&postcount=43
@mishua0: I agree with Kontex -> if your bootloader is locked there is no real risk at downgrading or upgrading through fastboot (I did it 2 or 3 time without any problem).

@[email protected] Including this thread you posted the problem in 3 threads. Yes, you should have opened a separate thread. Why should I format the modem partition? It didn't fix your problem so it won't fix mine. Let's face the ugly fact. The modem code is broken somehow and it is not possible to fix it without a working QPST-File. I read all your posts. You tried a lot of things.
I'll send my phone back to the seller and hope he will replace it with a new one that has an Android 6 Firmware. Than I do not upgrade it and I can use Xposed again. So far I'm happy with my Lenovo ZUK Z1 and don't need the Lenovo P2 immediatly.

So ? A few post is hardly spam on this small P2 forum...
And if I find a solution, I'll follow by the rules and create a specific topic for this specific problem.
By the way, regarding your problem: I myself didn't fully restored the modem part yet, but it seems that Bardales did.

Hi Kontex !
I'm so pleased to see your reply. I want to downgrade my bootloader locked Lenovo P2 from Stock Nougat to Stock Marshmallow. Actually I applied to unlock already, but I have 2 more days to finish my 14 days period. So, I think even after my 14 days period, if I don't unlock the OEM through fastboot mode, my bootloader would still be locked. Am I right ? It's just for talking. but I want to downgrade to marshmallow by tomorrow before ending my 14 days period. Please clear me which commands I should flash through fastboot. should I flash the following commands along with the systemchunk0-12 ?
fastboot flash partition gpt_both0.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash dsp adspso.bin
fastboot flash modem NON-HLOS.bin
should I erase the following commands, (specially what about modemst1 & modemst2 ? is there any risk to erase them?)
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
I don't want to create a bat file. I want to type the command one by one though that's lengthy and boring ! Is it possible ? and after finishing the last command (fastboot erase clogo), then what should I do with the command window ? please please help me to describe each & every step as you are expert to doing so and I'm totally new and I love my phone very much ! thanks a lot ...... waiting for your kind reply !

@mishua You should be able to use the flash.bat because your phone is locked. And you shouldn't type the commands one by one as you don't know what you are doing. Try the batch file first. As Itchi wrote if you like to play with different firmware images you can go forth and back anyway. Check the guide. The Bootloader is locked as long as you don't unlock it. It does not happen automatically after 14 days. After 14 days you have to enter the unlock menue again while being connected to the lenovo server. If you don't do this your phone is locked past this 14 days.
@[email protected]
edit: I couldn't resist and it didn't work:
fastboot erase modemst1
fastboot erase modemst2
After that. The SIM card is detected but the modem loses its connection within a minute as you already described in your posts.
edit:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2

Has the same effect as above. SIM Card is detected now, but doesn't get a signal.

Can somebody try the Device Rescue function of "Lenovo Smart Assistant"?
edit: I know I talking to myself. Anyway "Device Rescue" is not available for the P2 at the moment. Downloads only exist for other models like the P1.
edit2: To me to remember: Guide IMEI EFS Qualcom Reset , Qualcomm QPST Flash, Qualcom Lenovo Tools, Fastboot Images for Lenovo P2
edit3: Find someone who can make a full backup with QFIL QPST. It is decribed here.

Hi, I'm on same wave, but qpst look like (I want say solution try. Can anybody with functional modem make backup? Thanks for all brickers
I can try it in work, but up to two days, so maybe someone can be faster.

qcn backup
Hi here is qcn backup from working phone. To go to engeneering mode you have to press ####8899#. Smaller is from qfil tool, bigger is from qpst tool (software download). When I restored, I am back on internet 4G, can make or receive calls, BUT NO SOUND from speaker and MIC not working so. Any idea?

Newly bought Lenovo P2C72 issues.

I have bought a Lenovo P2C72 4GB/64GB..
Opened it then it prompted for an update (no sim yet).
Build Number: V3.5_1652_5.1342.1_ST_P2c72
After update I plugged in Sim card..
Some say If I plugged in Sim card it will auto configure to P2a42. It didnt for me.
I found out that there is no google play.
There were numerouse Chinese Play stores and bloatwares. I want to get rid of it.
How can I transfer to P2A42? I cant unlock bootloader.. I think it needs Chinese number.
-What are my options to get to a Global Rom?
I have downloaded a ZIP file for P2a42 Nougat Update (1.9GB). Can I just use this for update?
[Update]
Please correct me if what I'm planning to do wrong and I'll raise some questions about my plans aswell.
1. I downloading the fastboot files for P2a42. Q> Can I fastboot even if my bootloader is locked?
2. I'll flash all execpt the bootloader.img (because of modem issues). Q> Is bootloader.img different from boot.img?
3. After flashing via fastboot (if I get to this part without issues) Can I go to Nougat Update through OTA zip file?
3.1 If not How can I update to Nougat?
[Update2]
1. Flashed via Fastboot (https://www.getdroidtips.com/install-official-stock-rom-for-lenovo-p2-p2a42/) Skipped bootloader.img
Problem.. Im stuck at Lenovo Opening White Screen already performed fastboot erase userdata

[Update3]
Nothing seems to work. Stuck in White screen booting. PLEASE HELP!
[UPDATE 4: Its Working Now with P2a42]
Using this guide. (https://www.getdroidtips.com/install-official-stock-rom-for-lenovo-p2-p2a42/)
Flashed this via Fastboot (https://mega.nz/#!3hhhhRYC!bDbs1VGHA7s0n-uH-B30fVDsulFRVw-ZbYTvheS9m8I/)
Note:
I excluded/removed (bootloader.img) from fastboot folder
then used the existing flashall.bat file included in the zip file
Code:
C:\Program Files (x86)\Minimal ADB Tool>flashall
I got bootlooped probably because I used the answer by Undesirable. Made my own bat file.
(Dont get me wrong though, its good answer just not for me atm)

I have bought a Lenovo P2C72 4GB/64GB..
Opened it then it prompted for an update (no sim yet).
After update I plugged in Simcard..
However i found out that there is no google play.
There were numerouse Chinese Play stores and bloatwares. I want to get rid of it.
How can I transfer to P2A42? I cant unlock bootloader.. I think it needs Chinese number.

it's a diffrent device, you can't just "change to p2a42"

You should be able to put the row rom on it but it'll still be a p2c72 hardware wise (They don't have some 4g bands etc.)

I have a P2C72 as well, tried your method and it is working 100% first time, no boot loop!

Can someone please provide me a link to download the P2C72 Nougat Rom Chinese Version?
Thanks in Advance

Help. I'm way out of my depth. Moto G5s XT1797

Firstly I will apologise for my lack of knowledge. I had no prior knowledge of how android works, and I have been learning as I go.
Here is my situation: I wanted to remove guest mode from my Moto G5s Xt1797 so I decided to root it. I followed the following process:
Test everything on my old Moto G. Succeed and try the same with the Moto G5s
Attempt to use KingRoot. Fail
Unlock Bootloader
Flash TWRP
Install SuperSu
Install Root Check
Rootchecker says "Device is not rooted"
Reinstall SuperSu. Same result
Attempt to install Magisk. Fail because SuperSu is installed
Attempt to uninstall SuperSu. Fail because phone doesn't think it is installed
Give up and try KingoRoot. After two hours it reached 39% and I stopped it and went to bed
Check Root Check. It says "Device is rooted"
Remove guest mode using BuildProp Editor
Success!
Check Root Check. It says "Device is NOT rooted"
At this point I left it because I had accomplished my goal. However, a few day later I noticed a problem
...
Realised my camera doesn't work
Do some research, find that the kernel is the most likely problem
Install this kernel. (I didn't realise it was incorrect)
Now camera and wifi don't work
Try flashing another incorrect kernel. Fail to install
Give up on the whole thing and try to restore to stock rom using this guide. Fail at "mfastboot flash partition gpt.bin"
Accidentally wipe phone. Can't access wifi to reinstall anything
Give up on that
Create backup using TWRP
Install Lineage 14.1. Camera and wifi work, but I have no idea how to transfer personal information across. I can't even call my wife because I haven't memorised her number.
Realise that Lineage has guest mode, the very thing I was trying to remove
Restore Backup
Try to reinstall stock ROM using .bat file as in this guide
Failure. Receive "(bootloader) image size exeeded partition limits" ("exeeded" spelled incorrectly).
Camera and wifi still don't work
Remove SIM to put in old phone, realise SIM card is wrong size, replace in Moto G5s
Now the camera, wifi and SIM don't work
Start losing sleep over it all
Give up
Write this post
In a nutshell:
MotoG5s
Bootloader unlocked
TWRP installed
SuperSu semi-successfully installed
Wrong kernel installed
Camera, wifi and SIM reader not working
I would like to just completely return to stock, albeit with guest mode still disabled. I don't care about removing bloatware at this point, I just need to repair my phone. Please help. I'm sorry that I have nothing to offer in return, except my love.

Hey um sorry if i got your hopes up with this reply as I can't actually help much and am also not very informed on android phones and tech etc but am learning as I go. I just wanted to ask, for my own phone issues I'm trying to resolve: is your phone a motog5s or a mota g5s plus? Where did you fin the download for LineageOS for a motog5s and could I please have a link? If it's only for a g5s plus, can I have your opinion on if you think this would be compatible with the motog5s?

I have the Moto G5s. NOT plus.
I found the LineageOS download on this G5s forum. https://forum.xda-developers.com/moto-g5s/development/rom-lineageos-14-1-t3727918.
It worked fine for me. The only issue I noted was full screen video tended to glitch non stop

What error are you getting when flashing stock ROM? Did you install Moto drivers?
Replace "mfastboot" with "fastboot" in every command and try again.

Yes, Moto drivers are installed
Using the fastboot method I receive the error: "error: cannot load 'gpt.bin': No such file or directory"
gpt.bin is definitely in the folder, but fastboot can't find it
Using the .bat method I get much further before I receive: "(bootloader) Image size exeeded partition limits

I have the Moto G5s. NOT plus.
I found the LineageOS download on this G5s forum. https://forum.xda-developers.com/moto-g5s/development/rom-lineageos-14-1-t3727918.
It worked fine for me. The only issue I noted was full screen video tended to glitch non stop

Hmm okay thank you for this. And good luck with your phone!

Take your phone to the nearest service centre. Since your bootloader is unlocked, they might not help you but, I've got my Samsung and Vivo phones reflashed after I unlocked and bricked phones. You might have to request them a little.

Unfortunately, the nearest service centre is 900km away, so that won't be an option unless I get desperate. I have sent an email to Motorola support, so I'll see if they have anything helpful to say

Good news! I installed Resurrection Remix and now everything works. My only gripe is that it has guest mode. Does anyone know if I can remove it using build.prop like on stock Android?

Glad to hear your phone is working again. No idea about the guest mode.

just a question, why do you hate guest mode so much?

Wait for next security patch what was your old security patch is it April patch the gpt.bin doesn't flash because if we flash the old security patch

I am not able to relock!!!

I recently unlocked my bootloader and now i want to relock it.
I used this thread for relocking:
https://forum.xda-developers.com/moto-z-play/how-to/guide-relock-bootloader-to-lasted-stock-t3718190
But now at the end it says
still need signed boot.img.
Please help me.

Why do you want to relock the bootloader?

Well, i am selling this phone, so i want to relock the bootloader.

Ok, first of all, never EVER post anything that's longer than a few lines, especially no logs! just write them in a text file and attach it or at least put it on pastebin and look it here!
Second, did you try to flash latest ROM first? I can see a Security version downgrade there which looks like the bootloader of the ROM you try to flash is older than your current one. Are you sure you downloaded NPNS26.118-22-2-12 (or newer of you already got February patch)?

Look at https://forum.xda-developers.com/moto-z-play/how-to/mini-guide-bricked-special-case-attempt-t3812530
You could try to flash rafikowy's oreo stock signed with RSDlite, but if that throws an error, use the "alternative" method with either that rom or a 7.x stock rom, depending on whether your target is 8 or 7.
Do not go back to a 6.x rom!!!!!!!!!!!

Already try, adb gives me an error, but in rsd lite i instal any Stock ROM, but the z play wont charge.... Only charge when i turn off...

did you follow the instructions of "alternative" exactly - what error did adb give?
what rom did you use?

I use NPNS26.118-22-1_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
Adb give me a error in "write OEM"
And stop in sparsechunk 10

I thought you just gave me a log of where it didn't???

in the link rom that you passed me all the adb commands passed ... everything ok .... when I plugged the cell phone into the charger, it does not show the ray design on the battery indicating that it is charging, but the charge goes up slowly, and It also does not stay off, it keeps restarting ...

I am running rafikowy's stock signed upgraded to June.
power phone off.
Either with wall wart, or plugged in to computer, I get
flash symbol for a few seconds, circle showing (84%) battery status for 10-20 secs - at about 23 seconds it goes to blank..
check your cables/wall warts.
