[GUIDE] HTC Desire 626s Sprint - Sim Unlocking for GSM / LTE Band Unlocking

I successfully sim unlocked | unlocked LTE/GSM bands on the HTC Desire 626s Sprint variant using info from guides by [MENTION=5901467]be free[/MENTION] and [MENTION=2116175]dr.faramroze[/MENTION]. A big thanks to these fellas! You won't know it is unlocked until you put an active GSM Sim Card in. When trying a non active GSM sim it doesn't register correctly. I am unsure of why this occurs right now. When i get more time for this handset I will figure it out. I would recommend flashing the Unbranded MM 6.0 Stock Debloated Rom before doing these steps. It's much better and lacks all the extra garbage not needed. If you want to here is the download link - https://drive.google.com/file/d/1ZaQMcUMoGoKuZ781AJIKOrjubpx6frpK/view?usp=sharing

Instructions:

1a. Start by downloading all of the files attached to this thread. If they do not download you can download them from [https://www.androidfilehost.com/?fid=11410963190603843197] alternatively.

2a. Install HTC Drivers. If you do not already have them they can be downloaded from here - https://drive.google.com/file/d/0B3KA7QCJCJgwTzlfd0N6a3RXWVU/view?usp=sharing

3a. Run the application named "Basic-Flasher" that you downloaded in step 1a. If it fails to launch this is because you don't have the required run times installed. Goto microsoft.com and download the latest packages. If it still errors just click "continue" and then click scan, select your port # then click connect. Next to Method in the drop down box select [HTC]. Now click Read SPC and your MSL/SPC should appear. Copy this to notepad, piece of paper etc.

4a. Dial ##3424# in your dialer and input your MSL/SPC you got in step 3. Now Choose [DM ON] and activate it. IF it is already activated simply deactivate then reactivate it. Goto search or run and type in "compmgmt.msc" and goto device manager. You should see the HTC diag port under Com Ports. Now you know it is open.

5a. Run the application named "NV Items Reader and Writer". Click [Port] in the top left and select your phone serial port #. Make sure both boxes in the top bar are checked and input your SPC/MSL in the box replacing 000000. Click [Connect] then click [Read]. If all goes well at the bottom of the application you will see in the logs "SPC is correct. Phone Unlocked". Make a backup of ALL your current NV Items by selecting 0-65535 after Range (Dec) and clicking [Read]. Save this and name it "nv_items_complete_original_backup.txt". Keep somewhere safe that you will remember.

6a. Now in Range (Dec) input 30159-30159 and click [Read] and save this with the filename "nv_item_30159_original_backup.txt" and save somewhere safe. Now click [Write] and select the file you downloaded in Step 1 named "unlock.txt". Write the file. Now goto [Mode] in the top bar and click [Reboot].

You're now SIM UNLOCKED! -

Try your active GSM SimCard now. I'm testing with ATT getting HSPA+ and loving my horrible 3G data speeds! But hey what can you expect. =]

Now to enable LTE Bands if you must (Not everyone will be supported). This mod enables obtaining LTE - bands 2,3,5,13,17,25,26 after making changes to NV Item values. Band 5 is reported to be excellent with great coverage. Making these changes will not damage your Modem / IMEI / Hardware.
