IS WHAT I HAVE SO FAR NOTHING WORKS. I SPENT 600 ON THIS PHONE PLEASE SOMEONE HELP!!!!!!!!

First of all, the rom had it's OWN recovery? That is a rom that should not be flashed. It looks like the rom or recovery completely wiped the partitions on your phone. Have you tried getting into download mode?
Your mistake was factory resetting the phone on a custom rom. Don't EVER factory reset unless it is a STOCK based rom and you're doing it through the phones settings or you are doing it through recovery to flash a new rom.
Maybe try using Google's Android SDK? Maybe there is an issue with Minimal ADB.
I'm just trying to list some options.

Download the stock Firmware for your device, extract the files in your adb/fastboot folder.
Download that file https://drive.google.com/open?id=0B134drJ4-Ed0MHQ5aE1wUmp5eFk
and place it in your adb/fastboot folder. Run the batch fail and wait for complete. If that don't work, your partition table is broken.

yea it has its own recovery like it wasn't twrp when I booted in to recovery it just said recovery on top and said apply update and advanced and that's it. it wasn't twrp at all and ill try the listed options obove and update thread thanks you guys I'm a noobie to this

when I click your link it says url invalid

what is that file u linked in because it will not let me go to that url

Do u need stock firmware for US Addison? I had a tough time finding it but have it in my Dropbox if you need it. Along with fastboot TWRP etc. https://www.dropbox.com/sh/ndo7qz1h41rsv8i/AABeNwCnJojSGQuF4REAOCd3a?dl=0

https://drive.google.com/open?id=0B134drJ4-Ed0MHQ5aE1wUmp5eFk
Sorry copied the wrong link. Now it should work.

bro you are a life saver this twrp was exactly what I needed so I could flash twrp and get stock nougat it still tells me just n/a on the boot up but after 5-10 it boots like normal thanks man

That's a batch file to flash a complete stock firmware file. For me works the Link fine.

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 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.

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
Click to expand...
Click to collapse
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?

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.

[Help needed]

I seem to brick my phone. All I have now is original fastboot. I cannot install TWRP via ADB.
It says:
