For those who already have a QUALCOMM BOOTLOADER

1. Enter OSBL MODE.

WARNING: IF YOU GET FORMAT DISK MESSAGE IN WINDOWS - ALWAYS CLICK CANCEL.

2.Switch off the phone.
3. Press Volume UP and Power Key and wait for the short buzz abd release both butons. (To boot into NAND disk mode).

WARNING: IF YOU GET FORMAT DISK MESSAGE IN WINDOWS - ALWAYS CLICK CANCEL.

3. Run the oneClick DOWNLOADER (comes with the latest firmwares)
4. Choose the ROM. FLASH.
5. Once complete take the battery out; Re-Assemble, Switch on :)

OTHERS follow the following POST


NOTE: I do not take credit for any of the work by respective developers. I'm a lame user and that's my best quality. I would prefer things to be simple enough, if not I find one.

So for those who have been looking around for a Nokia Lumia 710 FULL UNLOCK and are jumbled with programs X, Y and Z and files A, B, C; everything seems right when your are following some steps and then, at some point of time, unfortunately for some it stuck and sucks. I've tried many things and the following is the one I like the most and find the easiest. Best of all, you don't have to worry about the DLOAD.

NOTE: One small mistake and you might brick the phone, so be careful.. I or the developers nor the forum is anyway responsible for your loss. But if you be careful, you won't have to worry.

READ the entire post and understand BEFORE you TRY

Step 1:
Download the required softwares.
( All required files are hyper-linked below )
i)> NSS PRO 0.48 or NSS PRO 0.51
ii)> QUALCOMM BOOTLOADER for Lumia 710
iii)> Depending on your system configuration, Windows USB Drivers either x86 or x64

iv)> Any one of your desired Custom ROM :

NOTE: You need only one ROM. so pick any. I've been using RATAPLAN's ROM.

Do Not Forget to thanks the Developer, whose ROM you are using.


Step 2:
Once you have all the files with you do prepare the program files for the FLASH.
a. Install the USB driver as per your system.
b. Extract the bootloader to a folder. You will get the following two files
RM803_12w07_prod_generic_nokia_osbl.esco
RM803_11w48_prod_raw_nokia_osbl.bin​
c. Extract the NSS to a folder
Now copy the two bootloader files to the following folder within NSS folder
loaders\special\wp7
Extract the Custom ROM to a folder. You should get a .nb file. If not, try another ROM​

IF you did the steps as stated, you are all ready.
Now before proceeding, make sure you have Enough battery back up on your phone and for the PC/Laptop (in case there is a powercut and you don't have enough backup, you won't have to but another paperweight.).


Step 3:
Flash your phone:
Did I Miss Something. No. You don't have to check for DLOAD. Not for Lumia 710. I already made it clear.
a. Connect your phone to PC. You don't have to do any button pressing or have to go to recovery mode.
b. Launch the NssPro.exe from the NSS folder in admin mode. Grant all the permissions the application asks for, if any.
When the allpication window is launched, make sure you know what is where. Use the snap for reference


Make sure, you select the USB port from port selection and alllow the application to detect the phone.
Once the application detects the phone it will show "Nokia USB connectivity.
Change the application mode to FLASHING
On the right side select WP7 Tools. You will get the Bootloader tools.​
.

c. Now refer the following screenshot and proceed.


i. In Advance Connectivity section select NORMAL Mode and then WP7 Qualcomm, if it does not detect automatically.
ii. In Bootloader tool select the OS file and locate your CUSTOM ROM to it.

Once you proceed further there is no going back. So be careful. Make sure that you have all the files in place as stated earlier and also you have installed all the drivers. Use CUSTOM ROMs for Lumia 710 only (Either your own or reliable developers). When Windows asks for format, ignore it. Do not respond to any pop up from any application other than the NSS. You should not leave the PC unattended for whatsoever reason. NEVER choose YES for FORMAT, simply close it.
iii. Hit the install. When asks for confirmation, select yes.
Wait for a while. Do Not Panic. Phone will go blank and will start in NAND DISK mode in a while. The connectivity mode will switch to NAND DISK DRIVE mode.​
. If Format option pop-ups, Select NO.
iv. Check the advance connectivity mode, and set as stated earlier to NORMAL and WP7 Qualcomm.
v. Hit the Write OS in the Bootloader tools. Wait for a while (usually 5 to 10 mins) Be patient. NSS will ask to restart the phone.
You cannot restart the phone. Take the battery out. Then again put it back and boot the phone.​
Close the NSS tool and any other pop-ups.

Your phone is now unlocked and loaded with a custom ROM

Step 4.
REACTIVATION of phone.
Your phone is ready to be used if you have used a correct ROM.

Sometimes, if you install a locked ROM or on on a Locked phone, your phone will be locked for LIVE ID usage. you'll have to ACTIVATE the phone to use LIVE login. You can still use other features though. Do not worry, as activation is as simple as chatting with a buddy. Just CLICK HERE and use chat and ask the customer care executive for activation code. They will need few of the details of the phone, and they will give the code. use this code to unlock LIVE usage.

Once again, I take no credit for the work. I'm just sharing the info in a clean manner. I use the method and works for me. Your Phone Your responsibility.

All links were alive when posting. If any link is dead, PM me. Response will not be prompt, but I'll make sure I respond to your requests.

Check prerequisite files.

Hi,

If the first part went right, you should have no problem for the second part. First part is the critical part here.
(Even I Had faced the same problem many times. Downloading and replacing the files should do it.)

Here are the possibilities:

If the first part went right; the phone will go to service mode; the USB should disconnect and reconnect automatically. You'll get the FORMAT disk message and you should select NO or simply close it.
If you accidentally click on YES, your phone is a gonner

If everything is correct, NOKIA USB CONNECTIVITY should change to NAND DISK. And you can p[roceed with second part.

NOTE
1. If first part is not pass, the second part cannot be initiated.
2. If first part is pass, the second part MUST be completed.

Hmmmm... Just the UNLOCK....

Well, That is completely upto you. But consider the following scenarios, b'cause I have no idea what your UNLOCK mode means.

Case 1: If phone software is not hacked, you cannot install YOUR own softwares without having to purchase from the MarketPlace. You'll have to install applications only through MarketPlace.
Case 2: If you think, installing the Qualcomm bootloader will unlock your phone, then you are mistaking; it will only enable your phone to install any firmware on it (simply saying it will be a dumb rock until you install a firmware).

Case 3: If your phone is carrier locked, and you want to use it on any other network: Simply insert the new SIM card and follow the LAST LINK IN THE ORIGINAL POST. But use it only after a fresh ROM installation or Phone Hard Reset.

Phone Detect

thanks for the tutorial

Howver for some reason NSS Pro doesnt detect my phone, (RUN as Administrator)

Hi,

Have you downloaded and installed all the files as needed. (All the required files are hyperlinked within the description).

It works for me on Win7, both 32 and 64 bit.

Make sure you have installed the proper USB driver for your system (from Step 1 / sub step iii). This is mainly the reason for phone detection.

Check if it helps.

Carrier Unlock

thnx for ur reply i understand it..and mine is case 3 i just want to unlock the carrier locked phone i have two phones with me but i dont have clear tutorial to unlock it if you know please guide me thnx in adv.
Installing the custom rom should debrand the phone.... Nothing more to be done.

Else use NSS PRO 0.51 in original post. There is a section to unlock the SIM.

Phenominal post!

I've successfully unlocked my Lumia 710 and flashed Rataplan V6.0 to my phone! Everything's working great, except I need to figure out my APN settings to get MMS working again. :L

The only suggestion I'd make for your Layman's guide is to make sure to let everyone know that they will lose anything that isn't backed up! Pictures, SMS, some contacts that aren't on your SIM etc. It may be common knowledge to some, but I didn't know. It's no big deal for me though.

Anyways, thanks a bunch! Great post!

Hi at all,
I have a Lumia 710 with DLOAD bootloader version 7.33.0 and OS version 7.10.8862.144.
Can I install a Custom ROM (Rataplan V7.0) with this method?
