Hi there, i am trying to help a friend re-flash his Lenovo A7000-A phone back to stock firmware but it after reading about it, i've come to know that the phone has two types of firmware ROW-rest of the world version and one other which is probably chinese. i was wondering if that is true and where i could get the non-ROW version. your help would be much appreciated. thanks
Is there any option to update from S133 to S136 (for example) via SP Flash Tool without wipe any userdata - like OTA update?
NOT GOOD. I have downloaded the Lollipop package from the link in the first post.
1. After applying it as described, the Home and Back button stopped working! Tried eMMC factory reset and did not help.
2. The OS occupied space still reported to be 3.13 GB, exactly the same as in Marshmallow!
Now I am trying to perform OTA update back to Marshmallow to see if the buttons would work again, even though I doubt they would...
BTW, in the Flash Tool >> Options >> Download >> there was just a single checkbox available: "DA DL All with Checksum" (version v5.1436.0, DA_v7.1436.00.000, libflashtool.so vBROM_DLL_v7.1436.01).

Hi friend, thanks for this tutorial.
I did all steps successfully, first as you said tick both options in download and done. But when I turned on phone see a Gary and white screen for a few second and then black, noting happened.
As you reply on another question like me I tried all steps but this time not tick the check box's in option. This time after turned on phone, just black screen. So again I do all steps as you said with tick in option. But again I face gray and white screen and noting loaded.
Can you help me on this ?
Tip: first time try this tutorial a face an error so I searched it and the answer was: first flash the device. So I flashed phone from flash tab in so flash tool then I tried this tutorial.
Thanks a lot for your time.
Thanks.
God Job.
No Problem.
Hi! I succesfully downgraded my phone to android 5.0 lollipop. Everything works fine except my sd card -it says my sd is corrupted but that's not true because on android 6.0 marshmallow that sd worked. I also tried different sd card but nothing changed. I even tried to format sd card but it still doesn't work. Is there some way how to fix it ?

Hello guys,
Here a easy way to fix a bootloop on your rooted Zenfone 2, if you make the error of apply an OTA while being rooted for example.
The only inconvenient of this method is that you will lost your internal data (like SMS, apps, downloads... But not your photos if they were in your SD Card). Another thing, you must have enabled the USB debugging before.
PS : I’m French sorry if my English is not perfect
Step 1
In your Zenfone 2, verify that you can go in fastboot mode : power off your Zenfone. Then, press the Power-On button until the phones vibrates twice. Release it, then go press the Volume+ button until this screen appears :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
If that works, connect your Zenfone to your PC.
Step 2
Now go in Asus Website for download the most recent stock ROM of your Zenfone 2 (size : around 1.1 Go) :
ZE551ML : https://www.asus.com/fr/Phones/ZenFone_2_ZE551ML/HelpDesk_Download/
ZE550ML : https://www.asus.com/fr/Phones/ZenFone_2_ZE550ML/HelpDesk_Download/
ZE550CL : http://www.asus.com/fr/Phones/ZenFone_2_ZE500CL/HelpDesk_Download/
Remove the SD Card of your phone and copy it the zip, you can do it after if your connection is slow.
Step 2.5
I’m not sure if this is mandatory but do it by prevention : install “15 Seconds ADB Installer” : here a guide for intall it :
http://forum.xda-developers.com/showthread.php?t=2588979
Step 3
When this is done, download the folder named : “CWM_Zenfone_2_Intel.zip” :
https://www.mediafire.com/folder/w70w7r1a65840/Zenfone_2
Extract the files, then open the folder :
Step 4
Run “cai_dat_CWM.bat”
Type “ACCEPT” in the command window, in capitals, then press Enter.
Then, if your Zenfone 2 is connect to your PC in fastboot mode and if the script is blue, that’s perfect !
Type “T4”, press Enter, and normally something like this will happen in your Zenfone 2 :
Step 5
Shortly after, your Zenfone will reboot in CWM Recovery Mode
With the buttons, go in :
Install zip > choose zip from external sd card > *name of the stock ROM* > Yes, install
When the installation is done, reboot your device, and normally the bootloop will be fixed ! CONGRATULATIONS :good: :victory:
i tried to wiped cache in recovery mode but before it completes i restarted the phone
so now when i start my phone it just blinks error bot and even when i select recovery mode same thing happens
i also tried to solve it with ADB method but it do not detect my phone
PLZ HEPL ASAP!
Worked! Thanks!
Thank you so much! :good:
It worked for me. Although I had to clear cache and dalvik cache before installing the zip, otherwise my phone would reboot into fastboot when trying to flash the zip.
And best of all: I didn't loose any data!! Just had to root again using method 3 and install busybox.
I edited my build.prop because on the Amazon App Store there is an app (Navigon Europe) that can't be installed because Amazon says my device would be incompatible which it isn't because the Play Store says it's fine. Anyway, upon rebooting I was stuck at the splash screen. Luckily I was still able to get into fastboot...
Thanks again!
Still doesnt boot up
Hi! Thank you for your guide! I ran into a bit of a problem, maybe you will be able to help me out.
I by mistake did an OTA update while rooted, and my phone is now stuck on ASUS logo. I tried to flash different roms from external SD card, but even though they install correctly, phone still does not boot....
Fastboot gives me "permission" problem, ADB says device not found....
Any help would be greatly appreciated, because I am about to give up and go buy another phone.
Thanks a lot in advance

Hello. I believe I did the same exact thing . Did you by chance ever get back into Recover y mode or get the PC to recognize your phone. I'm a total novice with this, and very lost. Thank you.
Yesterday I did it too. Follow this guide http://valuestuffz.blogspot.com/201...uck-in-recovery-wipe-cache-partition.html?m=1
i was hope ... but
Hi! there.
i spend last to days literelly trying to fix my zf2 ZE551ml, it gets frozen when i wipe cache so i force power off... what a mistake.
i was trying to fix it, and i got it worst. i think i erase recovery menu, so i can't adb sideload, fastboot saids that can not load image system.img, asus flash tool said "flash image failure (failed with error #1), xFSTK works to bring fastboot menu, but since i don't have the file to put on OS dns space, it didn't work, but, after hours and hours, in my last try of a long nigth, i did this guide.
when i see a cwm icon, i can't believe it!! almost made my entire two days, but suddenly, it was all sad, when i tried to install from external sd card it says that there is an error. And the problem still there. here is an option to install zip by sideload, but in de pc said not device detectec.
i really don't know what to do, i'm really tired, and my options are getting over...
any ideas??
Thank you all!!

Thank you for suggesting this guide! It did help me to get back into the recovery mode, however, after following the steps within the guide very diligently. I am still unable to get past the initial loading screen. . I received the permissions denied error just as the post suggested I would. I wiped the cache partition at the end of following the steps as suggested. Still. It will not load to the Welcome screen .
So I downloaded a 16mb OTA update and let the tablet do its thing without touching it. I waited for the tablet to boot up, but it was stuck in a black screen for about 12 minutes until I decided to turn it off and on. It didn't work, so I went to the recovery to do a factory reset and clear the cache, but it still didn't work. I later went to this Russian forum here from this thread. I downloaded a lollipop rom and proceeded to flash it using Phone Flash Tool Ver. 5.2. It went well until 16% in where it failed. Unfortunately, I don't have a screenshot of this.

After all this happened, I tried to start it up but I got the message "Boot Failed. EFI Hard Drive. Boot Successful - Enter Setup"
And now it won't go into recovery mode, but it does go into fastboot and bios setup.
Since it does go into fastboot, I tried to use a tool from this thread (Temp recovery) to use a temporary cwm recovery to hopefully be able to at least boot into that, but that didn't end up working.
I got another rom from the same Russian site that had differently packaged files but still the same stock lollipop rom.
I tried to just use the recovery from there to manually flash it using fastboot, but it still failed.
I later found this thread with these instructions for this problem.
1. download and extract this file someplace on your pc
2. uninstall your existing Phone Flash Tool and from the drivers folder install both files (Intel Phone Flash Tool and Android Driver accepting defaults) reboot pc when finished
3. place your tab in DNX mode (from power off press and hold both volume keys then press pwr to start, in a few you screen will show "Fastboot starting..." message and hang on that. you must get that message on your tab screen, restart from power off until you have it)
4. start the installed Phone Flash Tool and load flash.xml from the extracted YT2-830L... folder then Start Flashing, it will reboot when done

The file he linked in his post (ionioni ) was gone but I still tried to do this with the roms I had. And guess what? It still didn't work. The instructions said to place the tablet in DNX mode (meaning fastboot), which I did do...only when I put it into fastboot, it was set to DNX_OS which came to say "Wrong device state" in Phone Flash Tool.
I've tried what I could, but failed. Anyone have any suggestions?

Hi folks,
had the exact same issue and indeed the 1st link offered (https://drive.google.com/file/d/0B1LaMEhefCBgYzNTOUxJZmtWQ0E/view) worked like a charm.
The second link is to download the "Intel platform flash tool lite", but I used my existing version of the Intel Phone Flash Tool (5.2.1-0) which worked fine with the image.
In other words, Corasman, it appears you have saved 2 people's life (or at least tablets) with your solution, so Thanks ! :good:
Regards.
Make that 3 people! Thank you so much corasman - your post has finally fixed my yoga 2 tablet, which I was sure would be going in the bin. Can't overstate how grateful I am - Cheers!
update 830f with 1050f rom?
updating 830f with 1050 rom? does it work?
hello. I have the same problem. I update OTA to lolipop. Since the table is slow, i tried flashing some ROM (which i cannot recall) and the tablet stopped working. Now, I am trying to flash the link you provided and it succeed. However after that i get blank Screen. what Could be wrong. My table is YT2 830LC. Please help
I am typing this all over again after my full report vanished. Do not have the patience of typing all that again. Suffice to say I had a similar situation with the boot failed EFI Hard Drive. Boot Successful - Enter Setup" message on my 830LC.
I had even found the bios restore tool for moving back from lollipop to kitkat but it too would hang. And attempts to flash lollipop would fail immediately with the same message as the OP, wrong device state.
So, in spite of it seeming completely counter-intuitive, I flashed the 1050F rom in the link shared by Corasman. Strange as it may seem, my tablet is now alive and working. No calling function, but it is working and calling itself a 1050F.
Now my research has to shift to whether the 830 LC rom can be flashed now.
i have a same problem with yoga 2 pro 1380f mr corasmancan help me

Hi there ! Hope you're doing all right
I had a lot of issues recently with my phone : Crosscall Trekker M1
It all begin when I started to remove entirely Google from the phone.
I rooted it and took the liberty to delete all that mention google.
I unfortunately delete a system file and that how my problems began.
(I called couple of times the Technique Assistance from Crosscall's Website but they weren't able to help me and I had the same story with the SAV --> the after selling's services. I gave up about asking them help and I decided to solve the issue by my own.)
So for now the phone start on bootloop, (I cannot use the OS anymore) so I can launch it in Recovery mod only.
After days of researchs I found the original stock rom for the Trekker M1 !!
On the recovery : After I wiped data and cache of course :
I tried to install the Rom with the option : "Apply update from sd card" but it didn't worked.
So I tried to install differents Custom Recovery like CWM and even renamed them update.zip but I had the exact same issue:
"E : failed to verify whole-file signature
E : signature verification failed
Installation aborted."
I also wanted to try Odin but apparently Crosscall's phones doesn't have a recuperation mod (I dream that someone got me wrong on this :crying: )
I've got a few clues about all this :
I guess the Debugging USB Mod isn't enable anymore on the phone
Maybe the versions of ClockWorkMod weren't compatible at all with my phone.
All I know is that the phone is rooted;
The recovery's version is : "Android system recovery <3e> LMY47V release-keys"
So know you know everything
Does someone think, he or she can help me with this ?
Thank you for your attention !

So it appear that the Crosscall M1 got an emergency mode. I can launch it by pressing Vol + and Vol - when I'm plugging the phone to a computer by USB.
At this moment a message show up :
"Authority indentification not found !"
"Long press power key to continue ..."
and if I do it :
No update file in TFcard!
X
Update failed!
Long press power key to power off.
If I start the phone on Emergency Mode with QFIL working (what I need to do) nothing happen.
I still have the message No Port Available on the top of QFIL.
So I'm wondering,
Do you think I can fix in some ways that problem of unrecognized device ?
or
Is there a way that I can install the Rom by choosing to install it as an update with the Emergency Mode. The Rom files would be the update that i put before in a "TFcard" in some format ?

Hi, Here's the list of all the drivers I installed :
Qualcomm_USB_Driver_V1.0
MTK_USB_All_V1.0.8
ADBDriverInstaller
I also installed :
Android-sdk
Java SE Development Kit
After a lot of research my device still isn't showing on QFIL.
But for a time he showed up on "ADB Driver installer". I plugged the phone by USB and started it with a special combinaison (almost like the Emergency Mode's combinaison) that I'm still trying to remember.
There is also another a new thing. If I start my device that I plug before by USB and only with the power button :
My computer recognize it and the Driver Software Installation try to install MTP USB Device.
The operation failed everytime but for now I'm happy that the device is recognize.

wait you said that adb works, if you can find the file system from an exact phone uploaded or you know that its common you can push it using adb if you are rooted

Hello,
A friend give to me his Yoga2 1050F Tab, because it's bricked...
"After a kind of upgrade he said"
So, here's the situation,
Tab is really bricked, stuck on Lenovo Android Screen.
I've tried to factory restore, no success.
I've searched all the web after factory image to flash, I've found 3 of them... But nothing works !!
The 1st one, the only we can still found here, is a factory image from 2015. And the result is, no more lenovo android screen, i'm stuck on a kind of Bios (?) And can't do anything more...
2nd one, (YT2-1050F_S100196_151123_ROW-fastboot), best result, back to an android boot, but stuck on recovery screen, without any possibility to boot...
3rd one (YT2-1050F_S0198_150422_ROW) impossible to flash, it's always failed at "flash easyimage.zip" step.
Other thing, I don't know what xml file I need to use (flash, flash-blankphone, flash-factory ... )
Here, i'm totally lost. Tab is stuck, And I've no idea what can I do next...
Maybe here anyone can help me ?
Many Many thanks !
Hello,
It seem's i got the same problem.
The tablet downloaded an upgrade by it's own.
The tablet rebooted alone and the try to apply the upgrade but never success.
Now i'm booting on a BIOS type screen.
"VALLEYVIEW C0 PLATFORM"
I can access to different options but the tablet is not reconized by my PC anymore.
I can flash anything on it.
If someone have a solution, it would be great !
Hey @NeedaVirus,
Sorry to hear that the device is bricked. Just this past weekend, I've been sifting through all my old resources because a recent OTA (Yep, a 2020 update!) left both me and my partner's 1050F devices in an unbootable state. You can see we're not alone by checking out the thread on the Lenovo forums (https://forums.lenovo.com/t5/Androi...Tablet-2-1050f-system-update-2020/m-p/5007166). Unfortunately a large number of the very helpful resources on xda seem to have been redacted/removed over the past few years, which leaves a few people scratching their heads (I was for a while too).
Basically, the way I've always done this on the 1050F (and what worked yesterday again), is as follows:
1. Install the "IntelAndroidDrvSetup1.10.0". Google will find this easy enough.
2. Install the flash tool. Nowadays, "Intel Platform Flash Tool Lite 5.8.4.0" (might also be called Phone Flash Tool Lite v5.8.4.0 and again google will find this for you) seems to come bundled with all required drivers, so it's a simple process to install.
3. Plug the device in and put it in DNX mode. This mode is achieved by holding vol up + vol down and pressing the power button until the device vibrates. When you feel the buzz, let go of power but hold the other two until you see a "Fastboot starting..." message on a black screen. This is DNX mode.
4. Restore stock KitKat bios using the "restore-kitkat-bios-830-1050-v2" tool. This one might take a little finding and I'm not sure if sharing it here is acceptable any more. Provided the device is plugged in and in DNX mode (and you have the Intel Platform Flash Tool closed too), it's just a matter of running the bios restore tool and following the prompts. Make sure the flash tool is running on your local drive (usually C).
5. Once the bios is pushed, we need to restore the stock KitKat ROM using the platform flash tool.
First we need to set up the Platform Flash Tool, so open that and select "File" -> "Options". Under "Flash options" tick the "Force fastboot sparsing" option and select "500MB" for the size.
6. Now, we want to use the "YT2-1050F_S0198_150422_ROW" image and you'll need to extract it first. It sounds like you already have the right archive file for this, which is good because I'm not sure if a copy still exists here still.
In the Platform Flash Tool, hit "Browse" and the file we're looking for is "target_bin\flash.xml". Select that. (Side note: I suspect that if your device has been updated to Lollipop in the past, you wouldn't have had any luck flashing this rom without rolling the bios back first).
7. Put the device into DNX mode again, and the Platform Flash Tool should see it (a "Baytrail" device is listed).
Now it's just a matter of starting the flash process by clicking the button.
8. Once the device is flashed, you'll need to reboot it (via the device) but wait for the flash process to report 100% first. Hitting the device power button is the way to confirm this reboot btw. It might take a few mins to get into Android here. This is normal.
9. Now, the device will boot into stock KitKat. We need to set the region though:
Open contacts, add new contact (only if you have none, we just need one).
Now, using the contact search, enter ####6020# and you'll be prompted to select your region. The device will reboot and you'll need to set a few things up again.
10. Run all the OTA updates to get right up to date. Just do this via android itself.
Optional: Do any other crazy bootloader unlocks, roots as desired. A lot of the original resources have been removed for these processes, but where there's a will, there's a way.
I'm sure there are other shortcuts to this process too. I think tontonfraguer was able to just flash a newer rom directly to resolve his bootloop, judging by his forum post over on the Lenovo thread. This is just the process I use, any feedback/improvements are most welcome!
Hopefully it helps someone being hit by the recent bootloops.
Cheers
OMG ! OMG ! OMG !!!
Man, you're THE MAN !!!
I've followed all your explanations, and... IT WORKS !!!
Yes it was hard to find again the "restore-kitkat-bios-830-1050-v2" (China links to Russian Servers...) But I've finded it !
Many many MAAAAANYYYY Thanks my friend !!!
Thanks a lot !
And thanks a lot to All XDA DEV !

Managed to sort it out - many thanks for your guide. One thing to note is the Kitkit restore file needs to be in the root of the C drive and also the file for the flash in my case was the flash.xml file
Glad the post helped you guys out and that you were able to get back up and running. If the post was helpful, why not click the 'thank' button under my post
Hi Hi Hiiii
For those who need the famous "restore-kitkat-bios-830-1050-v2"
HERE'S THE LINK (Personal re-upload) : https://drive.google.com/file/d/13vV6fpNAbWWZUk9_fzmJpMAMax2tlyyB/view?usp=sharing
Be aware that you probably need to do this if your OTA updates Fails :
If system update fails do the following:
1. Flash stock firmware
2. Optionally you can wipe user data (I never did that) from DROIDBOOT
3. Go to contacts manager. Create some dummy contact if list is empty.
4. Go to Search / Find Contacts and enter ####6020#. It will ask you to select country code (first two latin letters, ignore Chinese).
5. Select what you want, then reboot.
6. Go to System Update
7. Install OTA update

Thanks - when setting the country code if you get the 'ERROR : could not read factory ota patch from sd card,or the patch is not correct.' then you need to take the easyimage.zip from the extracted rom folder and copy it on the sdcard (on the root of it not in some folder) then try again (with at least 30% battery level).
Guys,
If someone wants to ROOT his tablet, I can write the procedure. (Many try for me before it really works...)
See ya !

4. Restore stock KitKat bios using the "restore-kitkat-bios-830-1050-v2" tool. This one might take a little finding and I'm not sure if sharing it here is acceptable any more. Provided the device is plugged in and in DNX mode (and you have the Intel Platform Flash Tool closed too), it's just a matter of running the bios restore tool and following the prompts. Make sure the flash tool is running on your local drive (usually C).
5. Once the bios is pushed, we need to restore the stock KitKat ROM using the platform flash tool.
First we need to set up the Platform Flash Tool, so open that and select "File" -> "Options". Under "Flash options" tick the "Force fastboot sparsing" option and select "500MB" for the size.
6. Now, we want to use the "YT2-1050F_S0198_150422_ROW" image and you'll need to extract it first. It sounds like you already have the right archive file for this, which is good because I'm not sure if a copy still exists here still.
In the Platform Flash Tool, hit "Browse" and the file we're looking for is "target_bin\flash.xml". Select that. (Side note: I suspect that if your device has been updated to Lollipop in the past, you wouldn't have had any luck flashing this rom without rolling the bios back first).
7. Put the device into DNX mode again, and the Platform Flash Tool should see it (a "Baytrail" device is listed).
Now it's just a matter of starting the flash process by clicking the button.
8. Once the device is flashed, you'll need to reboot it (via the device) but wait for the flash process to report 100% first. Hitting the device power button is the way to confirm this reboot btw. It might take a few mins to get into Android here. This is normal.
9. Now, the device will boot into stock KitKat. We need to set the region though:
Open contacts, add new contact (only if you have none, we just need one).
Now, using the contact search, enter ####6020# and you'll be prompted to select your region. The device will reboot and you'll need to set a few things up again.
10. Run all the OTA updates to get right up to date. Just do this via android itself.
Optional: Do any other crazy bootloader unlocks, roots as desired. A lot of the original resources have been removed for these processes, but where there's a will, there's a way.
I'm sure there are other shortcuts to this process too. I think tontonfraguer was able to just flash a newer rom directly to resolve his bootloop, judging by his forum post over on the Lenovo thread. This is just the process I use, any feedback/improvements are most welcome!
Hopefully it helps someone being hit by the recent bootloops.
Cheers

on your screen, attached, at device manager, i can see the driver for intel adb fastboot blabla is not correctly installed, try:
1. restarting windows while holding SHIFT button till it restarts
2. go through advanced restart option and select startup settings
3. when it reboots and offers to select in black-white options 1-8, select wit button F7 the "driver signature.." part
( you are now allowing to installing unsigned drivers )
4. wehn it reboots, INSTALL intel plattform flash tool.exe again and re-install everyting, this time u will see windows pop-ups in red notifiying you installing unsigned extra extra drama drivers, say yes to all of them
5. flash again, using above instructions, make sure to change intel plattform flash tool settings to force flash 500MB
6. go everyting that is instructed above - step by step - through and report, i had exact same problem and solved it remembering the driver-stuffs weirdness on windows, still not a problem at all, just anoying extra steps

Hello,
A friend give to me his Yoga2 1050F Tab, because it's bricked...
"After a kind of upgrade he said"
So, here's the situation,
Tab is really bricked, stuck on Lenovo Android Screen.
I've tried to factory restore, no success.
I've searched all the web after factory image to flash, I've found 3 of them... But nothing works !!
The 1st one, the only we can still found here, is a factory image from 2015. And the result is, no more lenovo android screen, i'm stuck on a kind of Bios (?) And can't do anything more...
2nd one, (YT2-1050F_S100196_151123_ROW-fastboot), best result, back to an android boot, but stuck on recovery screen, without any possibility to boot...
3rd one (YT2-1050F_S0198_150422_ROW) impossible to flash, it's always failed at "flash easyimage.zip" step.
Other thing, I don't know what xml file I need to use (flash, flash-blankphone, flash-factory ... )
Here, i'm totally lost. Tab is stuck, And I've no idea what can I do next...
Maybe here anyone can help me ?
Many Many thanks !

Download Lenovo's official "Rescue and Smart Assistant" it reflashes stock rom for you.
Disclaimer
While I will assist with any issues resulting from this guide, I disclaim all responsibility and cannot be held accountable for any consequences caused by the use or misuse of this tool or process. This method also will wipe your phone, so please back up your data. I also will disclaim any understanding as to why exactly this works, since this method was developed by someone else, I am just listing the instructions on how to use it. With that being said, understand your personal limits and read this entire guide before starting.
Thanks to the attributed users at the end of this post, to find this method we are waiting for years...
METHOD 1:
Part 1: Requirements:
• To follow this guide you will need
A Windows PC
• Latest MsmDownloadTool for Oneplus IN2017 - Link
• Latest version of platform-tools - Link
• The bootloader unlock.ops file - Link
Plug your phone into your PC using a USB 2.0 port (this is important, USB 3.0 has given me a lot of issues and just doesn’t seem to work all the time) and ensure USB debugging is enabled.
Extract the downloaded platform-tools zip and open the platform-tools folder in a command prompt, and Run adb devices and makes sure your device appears in the list.
Next, extract the instantnoodlet_15_O.16_201001.zip and open up the MsmDownloadTool V4.0.exe inside the instantnoodlet_15_O.16_201001 folder.
When the application opens, select “Others” under the User type dropdown and hit next. Leave this window and the platform-tools command prompt open.
Part II: Entering Qualcomm EDL mode and installing correct QDLoader Driver
Part III: Flash Stock Firmware
In this section, we will flash the stock IN2017 Android 10 firmware.
Click the “Start” button in Msmtool. This will flash the stock firmware, wiping your data. Make sure you have backed your data up at this point. It will take a few minutes, usually ~300 seconds. Once it completes, it will reboot into factory default android 10.
Close MsmDownloadertool and once you are back to android, unplug your phone and power it off.
Part IV: Unlock the bootloader
In this section, we will flash the unlockable firmware and unlock the device for good.
1. Inside the directory with MsmDownloaderTool V4.0.exe, there should be a file called “instantnoodlet_15_O.16_201001.ops”. Remove it from the directory, either by deleting it or moving it to another folder. Then take the unlock.ops file downloaded earlier, and drag it into the directory and rename it to instantnoodlet_15_O.16_201001.ops . It should be in the same folder as MsmDownloaderTool.
2. Reopen MsmDownloaderTool V4.0.exe and like before, select “Others” in the drop down, and click next. Leave the window open.
3. Hold in the Volume up and down buttons, then plug your phone back in. Keep holding the buttons until your phone connects to your PC as "Qualcomm HS-USB QDLoader 9008", like before. Check device manager to ensure that it’s connected correctly as a COM port. If it boots to android, power it off and try again.
4. Return to MsmDownloaderTool. Make sure the phone is still displayed in the list under the associated COM Port.
5. Click start. The flashing should take about 15 seconds, and when complete, your phone should restart. It will display a message at boot saying “<!> The device is corrupt..” Do not panic, this is normal.
6. Unplug your phone and hold Volume Up, Volume Down and Power until the device reboots and let go once it shows the OnePlus Logo and “Fastboot Mode”. You should arrive at a screen that has “Start” in big green letters at the top, and “Fastboot mode” below it, with the very last item saying “Device state - Locked” in red text.
Plug your phone back into your computer.
7. Return to your command prompt window open in platform-tools, and run fastboot devices and ensure your device is in the list.
8. Finally, run the command "fastboot flashing unlock", it should prompt you to confirm unlocking the bootloader. Once complete, it should reboot into Android.
9. Shut the phone off again, and then Hold Volume Up, Volume Down, and Power and let go when the OnePlus logo and “Fastboot mode” shows up on screen. If the final item in the list says “Device State - Unlocked”, Congrats! You have successfully unlocked your bootloader. You can follow your custom OS’s installation guide from here.
If you want to flash back to stock firmware again (relock bootloader), you have to first flash this file (stock.ops) and then flash the bundled stock firmware. It will give a mismatch error if you do not.
So this is essentially the same as the IN2019 guide, just with the IN2017? Sounds neat.

yes. it works after I check allow oem unlocking before flashing the unlock.ops.
and dual sim works on oxygen 11, confirmed using my op 8 pro sim tray.
I see to prevent breaking the dual sim functionality, I have to use custom rom with magisk dual sim patch. But I see the custom roms are now based on oos 12. Can I flash oos 12 first and then to custom rom? will it break dual sim function?
