Hi Guys,
a german Forum advised me to ask here because, here are the experts. So sorry for my Basic englisch, but have a big problem.
My problem:
I got a Huawei Nova Youth as a gift. This is explicitly offered in the Chinese market. After some fumbling I have been able to change the language to German. However, the keyboard still partially takes false inputs. In addition, the Play and App store does not work. Of course, many other apps will be blocked, not to mention the Bloodware.
It is the model WAS-AL00. I now know that it is sold here as P10 lite. I did not find out how to install a European OS or a custom OS (Lineage). The support say only blah blah does not work, blah blah license problems ... Can someone please give useful information about my problem?
If more information is needed, I'll give it to you. I have always been Windows Phone users so far. So please apologizes if I do not understand all Android technical Terms.
thx

I tryed to do this.
I entered the developer steeings. 2 points are not present oem unlock and root access are both not seen. I tryed to install app store for twrp but it is blocked. If I try to enter the fastboot option with restart from smartphone, it is blocked. So I think the main problem is to get twrp to load new image. I tryed to install the with apk file directly and via huawei store. Both was not possible. Any Idea? Backup is not necessary. I never worked with the smartphone.
Update:
It was possible to download me.twrp.twrpapp-26.apk and copy on phone. Now he ask for device. Is the P9 plus the best choise?
ok you need first unlock bootloader:
register here with your phone(faster with it) or with email: https://emui.huawei.com/en/plugin/unlock/detail
then:
1º Download serviceRom(b182 or b183) on your pc and extract it, Same thing for oeminfo c432(ds or ss) and twrp.
2º Once you get unlock code open cmd(type cd c: /users/yourname/adb(more or less)), type fastboot oem unlock code , press on the screen and reboot wait to finish.
3º Move twrp image(extract) to c:/adb, type fastboot flash recovery recovery.img, type fastboot reboot and press vol+ till erecovery screen, poweroff and unplug then vol+ and power button(briefly stop pressing power button)
4º insert your sdcard on laptop and create dload folder in it, then copy update.app and folders from dload folder of downloaded service rom.
5º in twrp press backup button select sdcard storage and backup only oeminfo(copy to safe place), with downloaded oeminfo copy and replace oeminfo then restore.
6ºpoweroff and unplug, then press vol+- and power button untill update starts, if all goes ok should reboot.
at first big thanks foliaje. I am very happy for your fast answers. I tryed today the unblock page from hauwei. There was foolowing Problem.
1. I registered an account via Smartphone. Most of informations was chinese.
2. Change lange was not possible - same in PC browser. Seems like fix Region.
3. delete account and create new on PC. Change language to german was possible.
4. Try to login to unblock Website was not possible - Change Password Shows failure Email or account not present ....
Is it necessary to great account on Smartphone with fixed Region again and use this account for unblock?
Further *adb devices* shows an ID and unautorised device. Is that right?

Hi, I have this problem months ago, (I have a Nova Youth as gift too) and I solve it installing this app: gmsinstaller.apk or can use Googleinstaller.apk (just google it) and you dont need the root, it install the play services from Google and then you can install any app from the play store, sorry cause I dont have the apps to share but there is easy to find.
greetings from México!

=Part 2: Deodexing=
Firstly, what is deodex?
From @philo64:
Deodexed ROMs (or APKs) have all their application packages put back together in one place, allowing for easy modification such as theming.
The advantage of .odex file is the faster load time of the app and were supposed to quickly build the dalvik cache, removing them would mean longer initial boot times.
And finally rooting need not necessarily mean your device is deodexed, rather that almost all stock ROMs are odexed to some extent, and usually most custom ROMs are deodexed for easy theming.
For a casual user, the main implication is in theming possibilities. Themes for android come in APKs too, and if you want to modify any of those, you should always choose a dedoexed custom ROM.
In summary to install custom themes, install certain mods, you would need to have a deodexed phone. To check if your phone is deodexed, you can check at system/app/Phone.apk ===>where you will find this together with it ===> system/app/Phone.odex
Locked & Unlocked Bootloader
Required files:
FLASHABLE deodex zip
Link: http://forum.xda-developers.com/showthread.php?t=2690160
Note: Download the file which matches your phones model number. Please transfer this file to somewhere in your phone.
Requirements
Recovery is required for flashing.
Lets get started:
Flash the file
How to: Power off
POwer on phone
When phone vibrates press volume down
It will then enter recovery mode.
Install Deodex file that was downloaded.
Done! As simple as that!
=Part 3 :Unlocking Bootloader=
What does unlocking the bootloader do?
Unlocking the boot loader allows you to put custom ROMs on your device. Also, it allows you to install custom kernels that could potentially improve the performance, battery life and others. However, unlocking the bootloader can potentially brick your device if you do stupid things like cross flashing and others. So be warned, I am not really clear about the warranty status, do it at your own risks. Most probably nothing will happen.
:laugh:
Before unlocking bootloader, please backup TA just for precautions.
To backup TA, please use computer application: backup TA and run it.
Details and download can be found here: http://forum.xda-developers.com/showthread.php?t=2292598
Requirements and Warnings for unlocking bootloader
What you need to do:

To install a custom ROM(OS) on your HTC DESIRE 820

Click to expand...
Click to collapse
To install a custom ROM on your HTC DESIRE 820, here’s a brief tutorial guide:
---------------------------------------------------------------------------------------
Step 1. You will need to first download the custom ROM you want to install. These ROMs come in a “zip” file format (so DO NOT UNZIP them) and usually 1 large file around 200MB to 1GB. Some ROMs may require you to install multiple files.
You can download these zip files straight to your phone or use your computer to download (as downloading on your computer may be more stable/effective/faster) then copy over to your phone’s storage.
Step 1. Once ROM zip files are downloaded/copied to your phone, get into TWRP RECOVERY MODE BY PRESSING volume down+power button together for about 3 seconds to enter bootloader menu.Choose “RECOVERY” using Volume Down key then hit Power button to enter TWRP recovery.
Before installing a ROM, you will want to do a “data wipe/factory reset” by hitting the “Wipe” button. This will erase all your settings, apps, and app data (but not personal photos/videos on your storage). I highly recommend using Titanium Backup app to backup your apps, SMS Backup & Restore app to backup your SMS text messages, and use an online service such as GMail or Facebook to backup your contacts. Most online service providers like GMail or Facebook offer built-in ability to auto backup/restore your contacts.
*Optional – You can try installing a custom ROM without wipe, but this is considered risky and dangerous as sometimes the ROM may not boot. You can make a backup ROM if you are going to try this route so you can restore easily. Also, this can keep your settings, apps, and app data without restoring them.
Step 2. Once wipe is done (or you have decided not to wipe but have backup ROM), simply use the “Install” option in main menu and find the ROM zip file you need to install. If there’s multiple files, simple install them one by one until you are done.
Step 3. Once done installing custom ROM, reboot and cross your fingers your phone will boot. If your phone boots within 5-10 minutes you should be good to go. If not, you can try re-installing ROM, especially if you did not wipe, try re-installing after wiping.
To copy ROM file into SD card:
-------------------------------------
Boot TWRP, then select “Mount”, then select only “Data” and connect your HTC DESIRE 820 to your computer with usb debugging enabled.
Then download fastboot.zip and unzip, you probably will find a new directory called fastboot under your Downloads directory.
Copy the ROM you want to install to the fastboot folder.
Open a command prompt then type:
cd Downloads\fastboot
adb push ROM.zip /sdcard/.
Replace ROM.zip with the ROM filename you copied earlier to fastboot folder.
This will copy your ROM to the internal storage so once it’s done, just use TWRP to install ROM.
To backup the ROM after installing:
----------------------------------------------
Backing up a ROM will backup everything on your phone including your settings, apps, app data, kernel, and the whole ROM. It will not backup your personal photos or videos stored in your internal storage but it will backup everything else.
This can be handy later down the road your HTC DESIRE 820 malfunctions. For example, if your phone stops booting for some reason (due to bad custom ROMs or apps), you can easily restore your phone to a previous state by restoring your ROM.
If you “still” haven’t made a backup ROM, I highly suggest you to follow this tutorial to make a backup ROM.
Step 1. Make sure “Fast boot” is checked OFF under Settings->Power.
Step 2. Power off your HTC DESIRE 820. Then hold down Volume Down and Power buttons together for about 3 seconds to enter bootloader menu.
Step 3. Choose “RECOVERY” using Volume Down key then hit Power button to enter TWRP recovery.
Step 4. Once inside TWRP recovery, you can easily choose “Backup” or “Restore” to backup or restore ROM, it’s that simple.
Step 5. If you are backing up ROM, make sure “Boot”, “Data”, and “System” are checked and swipe to start backup. Backup process should take about 5-10 minutes or longer depending on how many apps you’ve installed on your phone.
Backups are usually large between 1-5GB depending on how many apps you’ve installed. They are stored in your internal storage under TWRP/BACKUP directory. You can easily save space by moving these files to your computer and move them back to the same location when you need to restore your phone.
Step 6. When restoring ROM, you will find your backups organized by folders. You can name your folders while backing up otherwise they will be stored with the timestamp of the time you backed them up.

It just the general rule of all companies to void warranty if the user root its device and same goes for HTC also, atleast in my country (India).
Do you have any rom for desire 820u dual sim?
Penish said:
To install a custom ROM on your HTC DESIRE 820, here’s a brief tutorial guide:
---------------------------------------------------------------------------------------
Step 1. You will need to first download the custom ROM you want to install. These ROMs come in a “zip” file format (so DO NOT UNZIP them) and usually 1 large file around 200MB to 1GB. Some ROMs may require you to install multiple files.
You can download these zip files straight to your phone or use your computer to download (as downloading on your computer may be more stable/effective/faster) then copy over to your phone’s storage.
Step 1. Once ROM zip files are downloaded/copied to your phone, get into TWRP RECOVERY MODE BY PRESSING volume down+power button together for about 3 seconds to enter bootloader menu.Choose “RECOVERY” using Volume Down key then hit Power button to enter TWRP recovery.
Before installing a ROM, you will want to do a “data wipe/factory reset” by hitting the “Wipe” button. This will erase all your settings, apps, and app data (but not personal photos/videos on your storage). I highly recommend using Titanium Backup app to backup your apps, SMS Backup & Restore app to backup your SMS text messages, and use an online service such as GMail or Facebook to backup your contacts. Most online service providers like GMail or Facebook offer built-in ability to auto backup/restore your contacts.
*Optional – You can try installing a custom ROM without wipe, but this is considered risky and dangerous as sometimes the ROM may not boot. You can make a backup ROM if you are going to try this route so you can restore easily. Also, this can keep your settings, apps, and app data without restoring them.
Step 2. Once wipe is done (or you have decided not to wipe but have backup ROM), simply use the “Install” option in main menu and find the ROM zip file you need to install. If there’s multiple files, simple install them one by one until you are done.
Step 3. Once done installing custom ROM, reboot and cross your fingers your phone will boot. If your phone boots within 5-10 minutes you should be good to go. If not, you can try re-installing ROM, especially if you did not wipe, try re-installing after wiping.
To copy ROM file into SD card:
-------------------------------------
Boot TWRP, then select “Mount”, then select only “Data” and connect your HTC DESIRE 820 to your computer with usb debugging enabled.
Then download fastboot.zip and unzip, you probably will find a new directory called fastboot under your Downloads directory.
Copy the ROM you want to install to the fastboot folder.
Open a command prompt then type:
cd Downloads\fastboot
adb push ROM.zip /sdcard/.
Replace ROM.zip with the ROM filename you copied earlier to fastboot folder.
This will copy your ROM to the internal storage so once it’s done, just use TWRP to install ROM.
To backup the ROM after installing:
----------------------------------------------
Backing up a ROM will backup everything on your phone including your settings, apps, app data, kernel, and the whole ROM. It will not backup your personal photos or videos stored in your internal storage but it will backup everything else.
This can be handy later down the road your HTC DESIRE 820 malfunctions. For example, if your phone stops booting for some reason (due to bad custom ROMs or apps), you can easily restore your phone to a previous state by restoring your ROM.
If you “still” haven’t made a backup ROM, I highly suggest you to follow this tutorial to make a backup ROM.
Step 1. Make sure “Fast boot” is checked OFF under Settings->Power.
Step 2. Power off your HTC DESIRE 820. Then hold down Volume Down and Power buttons together for about 3 seconds to enter bootloader menu.
Step 3. Choose “RECOVERY” using Volume Down key then hit Power button to enter TWRP recovery.
Step 4. Once inside TWRP recovery, you can easily choose “Backup” or “Restore” to backup or restore ROM, it’s that simple.
Step 5. If you are backing up ROM, make sure “Boot”, “Data”, and “System” are checked and swipe to start backup. Backup process should take about 5-10 minutes or longer depending on how many apps you’ve installed on your phone.
Backups are usually large between 1-5GB depending on how many apps you’ve installed. They are stored in your internal storage under TWRP/BACKUP directory. You can easily save space by moving these files to your computer and move them back to the same location when you need to restore your phone.
Step 6. When restoring ROM, you will find your backups organized by folders. You can name your folders while backing up otherwise they will be stored with the timestamp of the time you backed them up.
Download ROM file from HTC deire 820 android development forum they given your orginal ROM for installing.

Unable to download twrp recovery.zip please help me..
Be carefull of links which state there is 5.0 available for our device
drsobhan -
Please refrain from using or downloading ROM or any other files from other websites. The website you listed did not look genuine.
- HTC should provide us the with an update and source code will be available
- Cynaogen or other third party would provide us with an update
- XDA senior developers can provide link
One CM launches the rom there could be other providers like MIUI etc... but till the time please refrain from such websites

htc 820q root
I'm following this instruction and could not root my device,
My HTC 820q is unlock but when I want read SuperU.zip from Sd card at fastboot>recovery my mobile goes to restart and procedures been uncompleted.
Please help me, is this instruction only for HTC 820?
How we can root HTC 820q?
1. Go to secret menu of your phone (*#546368#*850#)
2. Tap SVC menu, then Version Info.
3. In Version info find NT Code.
4. Change wbatever code you have there to "1","FFF,FFF,FFFFFFFF,FFFFFFFF,11" - that is open europe.
After pasting the above code, the NT Code should display something like code write done, or similar, instead of your old NT Code.
This info is from MrBeem, he sent to me. I have this error but it did not work for me, i get Write Error maybe because i I dont have root. If you are rooted can work for you.
I get write error too. I think you have to have root to make this work.
Talking of which, has anyone got root on 7.0 yet?

From Mrbeem:
Hello. Got an update on the version error you have/had.
1. yes, you do have to be rooted, to get root u must het twrp-3.2.0-1-beta1-H850.img and SuperSu2.78 SR4. You flash twrp via minimal adb and fastboot, instructions on XDA forum, after flash, pull battery out, back in and you MUST get to recovery by Vol Down+POWER combination and you only get 1 try. If you don't manage to get to recovery and your system starts booting, you must flash twrp all over again. Once in TWRP, press skip if it prompts for password, enable read/write by swiping right, and install SuperSu zip file you have to have on your external sd card. With all that done, reboot and voila, you're rooted.
2. After boot, go to hidden menu, to ntcode. In the ntcode put "1","FFF,FFF,FFFFFFFF,FFFFFFFF,FF" notice, last 2 are FF, not 11. you should get NTCODE WRITE OK
3. with root acces granted go to cust folder and enable R/W option. I recommend using root explorer 4.0.4
4. Check subfolder list in cust folder. You will have folders like VDF_OP, EUR_OP or something like that. Pick any and memorize its name. this will become your soft ver. after you finish.
5. Find file named cust_path_mapping.cfg and open it with TEXT EDITOR!
6. at the end of the document, add a following line: FFFFFF,FF=/cust/name of subfolder in cust folder you memorized in step 4
7. save file, close it and reopen to check if your added line sticks. if it doesn't you haven't pressed "mount R/W" button in root explorer. Press "mount R/W" and repeat steps 5 to 7 .
8. Reboot, and now you should get your system branded (if you chose a specific carrier subfolder in /cust) or no brand and no version error (if you chose open europe in /cust).

You can flash your countries Rom, not EU
I've installed TWRP ans SuperSU as shown above, but I still get Write Error.
Looking in the SuperSU app, it says under "Install SuperSU into /system" - "Not (currently) available in system-less mode".
How can I fix the SuperSU issue, as I'm guessing that's why I haven't got write access to the NTT code?
Hi. What exactly do you get in your ntcode error? Mine was FFFFFF,FF is not a proper code or something like that. Now, if your error is something else but not '0', you can just do the following:
1. Memorize or write down your error code ( in my case it was FFFFFF,FF)
2. go to /cust folder, mount it as R/W
3. Check what carrier subfolders folders you have in your cust solder (i had OPEN_EU, P4P_PL and a couple more)
4. Open file cust_path_mapping.cfg with TEXT EDITOR
5. Change the number/letter string before = of your desired carrier in the above mentioned cfg file to whatever it says in your ntcode error (my error message said FFFFFF,FF, i wanted the P4P_PL to be my carrier so i changed 26006,06=/cust/P4P_PL to FFFFFF,FF=/cust/P4P_PL).
6. Save changes, close, reopen the cfg file to check if your changes stick (if not, make sure you've enabled the R/W option in your cust folder).
7. Reboot
This should fix your problem. I tried this on 5 different devices and always worked.

The NT code showing for me on my LG G5 H850 from the SVC menu is
"3","234,30F,

28000000,FFFFFFFF,FF","234,33F,
28000000,FFFFFFFF,FF"
(I'm on UK Virgin I believe - 234,38) and my stock Android 7.0 Rom is H85020k_00_VMC_GB_OP_0501.kdz Now,
I want to update to Oreo using the open EU oreo kdz H85030a_00_OPEN_EU_OP_0910.kdz as an upgrade file is not yet available for my phone but I get the customer not found errors on boot even if I first flash the phone using the original stock open EU Android 7.0 file H85020a_00_OPEN_EU_OP_1030.kdz.
I have my phone unlock code so if I unlock the bootloader will that allow me to enter a new NT code in the SVC menu to stop the customer error message without me having to root the phone and edit the root CUST folder? Thanks in anticipation.

Just wondered if you got any further with this? Oreo is now released for VM branded G5, but I'm wanting to use my VM branded phone on Three with WiFi calling. I was thinking about changing 1 of the 3 NT Codes (30,33,38) to 20 for Three but not sure if that's the best path forwards.
No progress with changing NT code

Sorry - I wasn't able to resolve that issue but as you say the G5 has now received its Oreo upgrade which is really all I wanted. Good luck anyway

Did anyone work out how to change the NT Code via the hidden menu? I tried downgrading to Marshmallow but still get a write error.
Thanks
This is a solution that worked for me, on a Wind branded phone with an OPEN_EU rom (root required):
go to /cust/ folder and edit cust_path_mapping.cfg, adding a new line with the code you see in the NTCODE error (22288,FF in my case), pointing it to the OPEN_COM folder:
22288,FF=/cust/OPEN_COM
Then do the same with open_path_mapping.cfg, but here you should put OPEN_EU instead of OPEN_COM:
22288,FF=OPEN_EU
Then, after saving both files, reboot the phone, and the NTCODE error will be gone.
Greetings to all.
I have a Redmi 2 Prime, I'm in Spain and I'm using Vodafone 4G network. Everything was working fine, but I couldn't use the Netflix app, so I had to update.
I used the Updater (that's the OTA update I think). It didn't install, so I downloaded the "fastboot" rom and installed it. After the install, the phone booted and it asked me for the PIN of the SIM card, then the configuration process started as if it was new (I chose clean install). The problem is that it doesn't connect to the Vodafone network.
I read similar problems in the past, so I though that going back to an older ROM will solve the problem, even if I couldn't use the Netflix app. So, I installed an old ROM V7.5.2.0.LHJMIDE. No luck neither.
Can you tell me how to solve this issue? What ROM should I install, even if it's and old one?
Thanks in advance.
Flash miui zip again try and send review
Exact model is: 2014813 TD-LTE
I've been trying for days now. I've got it running again but on an english ROM and my wife can't understand english. I can't find a Global ROM to install from fastboot, since OTA ROMs won't install. Need spanish language.
I had to change the modem file on the fastboot image. What a joke this Xiaomi updates...

Yes, that device is china model. You cant install rom global version. Try flash 8.5.1.0 china rom.
Thanks for the comment.
Why would I install a chinese ROM if I won't understand anything?
I already solved the problem downloading a ROM from the Xiaomi.eu site and changing the modem file.
Such a crappy way to update a phone. 2 days (+10 hours) investigating and working on the phone to update it.
suggestion:
1)Backup all partitions via TWRP, in case anything goes wrong.
2)Go to page http://en.miui.com/a-234.html , download "☆ Redmi 2 Prime Latest Global Stable Version Fastboot File Download"
3)Go to page http://en.miui.com/download-261.html#441 , download full rom (stable rom, Redmi 2 Prime Global)
4)Go to page http://en.miui.com/download-261.html#442 , download full rom (stable rom, Redmi 2 Prime China)
5)"Extract files..." via 7zip the file downloaded in step 2. You'll get a folder named "wt88047_pro_global_images_V8.1.3.0.LHJMIDI_20161230.0000.00_5.1_global_23ac47dab8". Shorten the folder name. Inside the folder is another file "wt88047_pro_global_images_V8.1.3.0.LHJMIDI_20161230.0000.00_5.1_global_23ac47dab8.tar". "Extract files..." via 7zip this file. Shorten the folder name. Inside the folder is another folder named "wt88047_pro_global_images_V8.1.3.0.LHJMIDI_20161230.0000.00_5.1_global". Shorten the folder name. Inside this folder is your workplace. Copy your adb and fastboot files and folders here.
6). Copy the file downloaded in step 3 ("miui_HM2XWCProGlobal_V8.5.1.0.LHJMIED_447abeac98_5.1.zip") to your phone's external memory.
7) Extract the file downloaded in step 4 and go inside the folder named "firmware-update". Copy the file named "NON-HLOS.bin" into your workplace(remember?step5).
8)Get ready for the flashing job. Charge you battery. Ensure you have backed up all personal files from your internal storage. Ensure you have your apps data like Whatsapp media backed up. Take a cloud backup. Now get into your workplace, Shift+right-click and select "open command window here". Connect your phone in fastboot mode to the PC. type "flash_all"(without quotes) in the command prompt and press Enter. Let the job proceed. Lastly your phone will reboot. It'll take some time until setup screen is shown. Don't bother. Just skip all details and go to home screen. Go to updater and select updater package in your external memory(remember?step6). Your phone will go into recovery mode to apply the update and it'll reboot. Again wait a few minutes for setup screen to appear. Don't proceed. Switch off.
7)Swith on into fastboot mode. Open command window inside your workplace. Ensure your phone is connected to your PC. Type "fastboot flash modem NON-HLOS.bin" (without quotes). After the flashing has been done, type "fastboot reboot". That's it.
8) Any future updates as a zip file will replace the modem. You can only flash in fastboot mode (after replacing modem file). It is a difficult process to unpack a zip, change it and repack with proper signing and/or checksum so that the stock recovery accepts it.
9) I don't know whether other firmware files also need replacing, but I don't think so.
And FYI, Chinese ROMs also have English language, what they don't have is gapps, and opengapps cannot be installed.
Hi,
So many of us are not happy with the oreo rom of Honor 8 Pro (C675). Those who looking forward to downgrade from Oreo to nougat just follow the steps. (This method is tested and is working. I just finished downgrading and is working perfectly fine. I just want to share this method with you guys. Also this i my first post in the forum. Some steps have been copied from a previous post by xfact)
Things you might need :-
>>A computer
>>At least 8GB memory card.
>>An unlocked bootloader. (you can relock it later)
>>Download the necessary files here :- [The Dload file was previously shared in this forum by xfact, but the link is not working now. Fortunately, I downloaded the file while it was available and I am providing the link to the google drive backup.]
REMOVE THE *** IN BETWEEN THE URL'S
(a) Dload File --- https***://***drive.google.com/open?id=1ZpOoPZ3dEn86lEh0PwlZP0W2LShM-BnT
(b) Recovery File --- https***://***drive.google.com/file/d/1qiP4k5HtJ3VR5l9ac8FnpxrwryIxu-pV/view?usp=sharing
(c) ADB platform tools --- https***://***drive.google.com/open?id=1vu-awRNjH3B9os5MuHGSlu-ca6zNv10V
>>Unzip the above-mentioned Dload file, then go to the folder, then software>dload folder and unzip the 'SDupdate_Package.tar.gz' with 7-Zip. It will extract another archived file called 'SDupdate_Package.tar'. Now unzip that too with 7-Zip and you will get a folder called 'dload' again.
>>Now take an SD card with at least 8 Gb of space, format it to exFAT. Paste the last 'dload' folder and all its contents at the root directory of that SD card. Put it into your phone.
>>To unlock the bootloader, just log into---- https***://***bit.ly/2uEEvdj
This is their chinese website, use translator in chrome to read in english.
Fill up the necessary details and you will get an unlock code for your device.
>>Follow the necessary steps to unlock your bootloader from here :- https***://***bit.ly/2uEM1F8
>>After unlocking the bootloader, your phone will be factory reset. When the phone boots up again, go to settings and enable USB Debugging from devoloper options.
>>Unzip the platform tools zip file and copy the Recovery file into that folder.( you have to unzip the platform tools file while unlocking the bootloader. Just copy the recovery image to that folder)
>>Holding the SHIFT key, right click any empty spaces in the folder and from the menu that appears, select "Open command window here"
>>Connect your handset. Ensure USB debugging prompt appeared as seen in the bootloader unlocking tutorial.
>>In the command window type the following commands :-
1. adb devices
(this is to make sure your device is connected properly)
2.adb reboot bootloader
(to put your device into fastboot mode)
3.fastboot flash recovery_ramdisk DUK-RECOVERY_RAMDISK_NoCheck.img
(to flash the recovery image)
4. fastboot reboot
>>When the device boots up, go to the dialer, type *#*#2846579#*#*
->Click on Software Upgrade -> SDcard upgrade->confirm.
Your phone will recognise the memory card with dload file in it. It will flash the rom. It will get stuck at 99% and shows error. Dont worry, just select reboot system option that appears on the screen.
You will be on the Nougat Rom
To relock the bootloader--
>>Again you have to enable USB debugging from devoloper options>>open command window from the platform tools folder>> execute the commands 1 and 2.
Then type the following command :-
fastboot oem relock *unlock key*
(replace *unlock key* with your unlock key used for bootloader unlock)
YOUR DEVICE WILL BE ON NOUGAT ROM WITH LOCKED BOOTLOADER
As this is my first post, kindly ignore the errors. Sorry if this lengthy post made any confusion. Hope this is helpful to all of you.

>>Unzip the above-mentioned Dload file, then go to the folder, then software>dload folder and unzip the 'SDupdate_Package.tar.gz' with 7-Zip. It will extract another archived file called 'SDupdate_Package.tar'. Now unzip that too with 7-Zip and you will get a folder called 'dload' again.
>>Now take an SD card with at least 8 Gb of space, format it to exFAT. Paste the last 'dload' folder and all its contents at the root directory of that SD card. Put it into your phone.
