[Sony Cross-Device General] TheDrive:
Original file is named Unlock_bands_of_your_qualcomm_device!.zip

It has size 23.61MB (24759994 bytes) and MD5 Sum: b3d396d9d015aa3e3a51204a6d7d0d51

Now Dev-Host (d-h.st) experiences some strange 'problems'. They ban AdBlockers (ask to remove - this manner is against AdBlock rules) and show HTTP Internal Server Error 500 instead of file downloading. On other hand they 'offer' 'Premium service' at the 'reasonable price'.

It seems guys have collected a bunch of the unique free files and try to sell them.

Money is a devil's matter. Are you so greedy getting tons of bucks from ads? We'll find what we need for free and make the mirror links.

Original file contains the following parts:

1. QPST 2.7 build 411 (This one contains RF_NV_Item_Manager utility) to perform NVRAM read/write operations.

(You can get various versions of the QPST here: https://androidmtk.com/download-qpst-flash-tool )

2. mzTool 1.2.1a utility by Hwang Minjae

This util required to build channel map binary masks, then convert them to the single number to write the value to the NVRAM.

(Perviously hosted here: https://sourceforge.net/projects/mztool/ Now forbidden)

3. Modified HTC Diag Port Driver

Qualcomm devices mostly oprated through virtual Diagnostics COM port.

This port is hidden in the default user-level USB composition in the most of devices.

That's why you should type in the 'secret code' and set eng mode by the variable changing? as stated in the manual.

All these files except modded driver, you can directly download from this japanses page:

If you have QPST already installed you' re not required to download it again.

corpcz have published Google Drive (and Mega) link above.

His archive. named 'all you need.7z' contains the following parts:

1. QPST 2.7 build 460 (0day one, doesn't include NV_RF_ITEM_Manager)

2. NV_RF_ITEM_Manager (RF_NV_Manager) from some previous QPST Build 2012.

3. MZTOOL-1.2.1a.zip (includes req'd dll)

4. HTC_BMP_USB_Driver_x64_1.0.5375.msi

5. Xperia Z3 Rooting Package .291.zip

6. Modified HTCDiagDriver.zip (same as in original package)

7. QXDM-3.12.714.rar (2013, what for?)

8. QPST-2.7.374.rar (2011, what for?)

Please NOTE! RF_NV_ITEM_Manager is an obsolete Qualcomm utility to edit NVRAM driectly in the phone. In many situations it does definitely damage NVRAM contents. Firthermore these damages in the variious practices often stay hidden and not easly discoverable. Device may lead into the strange and occasional network-related problems without any clear signs on what is going on. Also, in no case does RF_NV_Item_Manager support secondary SIM NV-data in dual SIM phones. Many people including official developers have had expreienced serious problems with this util. That's why Qualcomm decided to fully remove it from the latest builds (since 415 or 420) even though it required for old school 2000's obsolete Qualcomm chipset devices (e.g. Seimens/Benq).

The official way to edit NRAM and/or QCN backups is to use sepcial features of QXDM or use QRCT utility of the QDART package. I've tryed some command line qmsl_nvtool_msvc10r.exe of QDART to convert between QCN and plain text XML and it doesn't support dual SIM configuration (ignores and loose SIM1 structures of the NVRAM). OEM's customize Qualcomm reference software as they want. So...

The correct way to fix variable is to backup whole NVRAM contents using QPST->Software Download->Backup to the .QCN file, binary patch it with some HexEditor, then Restore patched .QCN backup back to the phone. This way should quarantee correct NVRAM maintenance for most modern Qualcomm-based phones.

If you are 'afraid of hex' and you would like to escape and hide as soon as you listen this word with your ears:

At least!!! Please make a QCN backup before trying to use RF_NV_Item_Manager to edit NVRAM directly in the phone!!! In case of any troubles (including ghost-related :)) you will be able on the safe side and able to fully recover your original NVRAM contents!

For the guaranteed accessibility I've attached all the required files to the message body.

Rename all .rar.zip files to .rar (remove .zip extension) and unpack with Rar-supporting archiver. Files renamed to overcome strange forum limitation when attached .zip files could be 20MB long and .rar files are limited to the only 8MB. 4 parts contain QPST installation package in one 61MB file as got from androidmtk.com .
