11. Inside the NV Browser window,
Scroll down and click on line 01877 (rf_bc_config)
Click the Read button save original value in notepad in case something goes wrong.
Replace Input value with 3460734838925427584
Click on Write button.
12. Inside the NV Browser window,
Scroll down and click on line 00946 (band_pref_16_31);
Click the Read button, save original value in notepad in case something goes wrong.
Replace Input value with 0x0FF8 (please don't be an idiot and don't edit the empty one with "nam" in the name)
Click on Write button.
13. Inside the NV Browser window,
scroll down and click on line 02954 (band_pref_32_63);

click on Write button.
16. Now Close QXDM; Wait 30 seconds,
disable Android Debugging on your phone,
unplug it and reboot your device;
Once it comes back on, it might take a minute or two for it to acquire signal so don't panic.
DO this on your own risk.. No body is responcible for any lost
Conclusion:
The only real way to know if the whole thing got applied is to do steps 1 through 10 again (obviously skipping installations)
and reading all values or if you are in an area where you previously had bad or no reception.
You can see unlocked GSM/UMPTS bands from the *#*#4636#*#* /Phone information /Menu /Select radio band

Don't forget to put check marks on dual sims, and apply all settings to sim0 and sim1 (see attachment). By the way before u messed things up, back up your modemst1, modemst2, fsc, and fsg.
By the way we can also use qxdm to recover lost imei, just go to 0550, and insert your imei for SIM 1 (sim0 in qxdm) and SIM 2 (sim1 in qxdm), for example:
Code:
If your IMEI was: 954091051099226, then the boxes would look like so:
8
9a
45
90
1
15
90
29
62
or also recover lost esn (item no 0 and 5597) or meid (1943 and 5598).

Need help for prevent NV recovery from you all

If it's the same as the 1+1, replacing /system/bin/rmt_storage with a version not locked would prevent nv recovery (do you know if NV values were sticking in an older version? If so, take it's rmt_storage and try to replace current one with older one, I think it's worth trying)

Hmmm, as far as I know, all NV settings, including IMEI, or MEID, ESN, etc, resides in your modemst1 and modemst2 partition. If you don't believe me and eager to try, first make a backup of those two partitions, then format or wipe the two partition inside your phone (use fastboot to do this), I'll bet for your YU, now your IMEI and NV settings are all gone.
To be honest, I just found out from this thread that there is an rmt_storage in CM phones, wkwkwkwkw, . If the rmt_storage function is trough, then CM is locking the phone NV settings from the HLOS side not Non-HLOS side. I'll do some research on this rmt_storage.

Need Help from your side

@tirta.agung
I read your complete Guide regarding unbrick YU
but as that post has multipal guides ... I little confused ..
Sorry I am Xtreme noob for all that
Can you guide me an easy way to connect with QPST for enable LTE band
Can I try
Guide #3. REVIVING YOUR IMEIs (That for 32bit or 64bit)??
for connect QXDM

Hi there, attached is boot.img and a hack rmt_storage for CM 12.1. Just flash the boot.img to your phone and connect it with QXDM. Your phone will be recognized as qualcomm diagnostic port 903A. Copy and paste (you can use TWRP's file manager to do this) the rmt_storage to "/system/bin" and change its permission (chmod) to 0755. This will make your changes stick upon reboot.
By the way, to use all these files, you need to be on stock CM 12.1. I haven't tried it on any other ROM.

Bro...im on cm12.1 ...rooted...I didn't understand the procedure... Pls can u explain step by step ..pls....wats that qxad ..? Is a software...? Wer I get that..,pls reply bro

I have tried doing this on Yureka - CM11 XNPH05Q. Installed all the drivers & softwares successfully. When I startup the QPST config to add a new port,
1. I have to uncheck the "Show serial and USB/QC diag ports only" to make the HTCUSBModem port visible.
2. Although I am able to add the port successfully I am unable to see the phone number, it says "No Phone".
Since it is unable to get the phone details I am unable to proceed further. Nothing is visible/editable QXDM. either.
I have manually edited the build.prop file to make sure USB debugging is enabled but to no avail. Please check the attached files, what is it that I am missing?
P.S - I am able to get my IMEI number using *#06#

Any suggestion Guys???

Hi friends We often suffer hard brick in our devices .
Even after flashing stock recovery . IMEI is not recovered
its easy to recover imei in MTK based devices but when it comes to qualcomm based devices
it is a big mess

Just reinstall your rom by wiping internal storage also. Then let the phone boot. Don't install gapps for quicker bootup. Then after restoring imei flash the rom of your choice. Try cm nightly first for recovering imei.

I was on cm13 unofficial build. I tried qxdm professional but there was this write protected error. I connected my device in fastboot mode and erased system. Then hotbooted TWRP (latest) and flashed the same rom again after wiping data and internal storage using rm rf. Then i let the rom boot up. (Without Gapps). Then i again tried the same steps as mentioned above. And after i got imei back, i rolled to my favourite rom. Hope you get back your imei soon.

Programming modem with QPST/QXDM on Boost Desire 626S

Hello everyone. It's been heavily requested that I create a guide on how to program the values I provided in one of the posts on my previous boot image thread into the Boost Desire 626S modem so I decided to take the job into my own hands for your convenience.
First you will need QPST, QXDM, and the modem diag usb driver if it is not already installed on your computer. Here are the links:
QPST:
https://www.sendspace.com/filegroup/XynIcslf8H6Qm2TsJ5z4ZEocT85CdvbS
QXDM:
https://www.sendspace.com/filegroup/XynIcslf8H6Qm2TsJ5z4ZEocT85CdvbS
DIAG DRIVER:
https://www.sendspace.com/filegroup/XynIcslf8H6Qm2TsJ5z4ZEocT85CdvbS
1 --- INSTALLING SOFTWARE / DRIVERS
Run QPST.2.7.425 from the QPST folder in the QPST.zip archive and install it by clicking next through the dialog box at each step.
Run QXDMInstaller from the QXDM folder in the QXDM.zip archive and install it by clicking next at each step as well.
Run HTC CDMA LTE DIAG Modem Driver v3.0.2.0 from the inside the DIAGDRIVER.zip archive and you've got everything you need to now program the Boost Desire 626S modem.
2 --- SETTING UP USB DEBUGGING
---First you will need to enable usb debugging.
---Connect your Desire 626S to a usb port on your computer.
---Open the settings app and scroll to about and select it.
---Next, select software information then select more and tap on build number 7 times.
---This will enable access to Developer Options in the settings app.
---Tap back three times and you will now see developers options as selectable in the settings app.
---Tap on developer options and scroll down a bit to USB debugging option.
---Make sure it has a blue checkmark next to it so it is enabled.
3 --- SETTING UP DIAG USB ACCESS
---Now we will enable usb diag access to allow communications with QPST/QXDM.
---On your computer with the phone still connected, open a command prompt as administrator and type adb shell then hit enter.
---Or if you are using minimal adb and fastboot installation, open the shortcut for it as administrator and type adb shell then hit enter.
---On your phone, tick the box next to always allow and tap ok.
---You might have to type in adb shell again and hit enter.
---Do so and you will see [email protected]_a32ewhl:/ $ at the prompt which means you have shell access.
---Now we need root shell access.
---With the shell access, type in su and hit enter.
---Allow the root access for adb shell in the supersu prompt that pops up on your phone.
---You will now see [email protected]_a32ewhl:/ # in the command prompt window.
---Congrats you now have root access.
---With root shell access type this in and hit enter in the command prompt window:
echo 1 > /sys/devices/virtual/android_usb/android0/f_diag/func_en
---You might hear a ding and you have now enabled diag access to use QPST/QXDM in order to program the modem.
4 --- SETTING UP MODEM DIAG COMMUNICATION
---To open QXDM, click the orb in the bottom left hand corner to open the start menu and then click all programs.
---Scroll to QXDM Professional and click it and then click the next QXDM Professional shortcut under it.
---QXDM will now open so now it's time to access the diag port to the modem.
---Click on options in the bar towards the top of the window and then click on communications.
---Under target port, click on the box that says disconnect and click on the available COM port whether it might be COM1-5 then click ok.
5 --- PROGRAMMING MODEM NV ITEM VALUES
---Now we are down to the nitty gritty, actually programming the values for the bands in the modem. It is actually quite easy to do if you figure out what needs to be done.
---Click on the box next to view on the second bar down and click on the NV browser option to open it.
---In the NV browser window you will see some of the first typical NV items that might be included in a modem firmware but we are looking for the certain ones we want to edit to change bands and functionality.
---Left click the up and down arrows on the scroll bar and hold the left mouse button to slowly scroll from item value to item value if you need to, and slowly drag the knob on the scroll bar up and down if you require quicker navigation through the NV items.
---Once you reach an NV item you want to change, for instance, item 1877, click it and in the box under fields section you will see the input field used to change the following value field are both 0, followed by the respective nv items true name.
---To retrieve the content of each field for item 1877 or any nv item, click the read button in the bottom right hand side of the nv browser window, and you will be presented with the fields contents.
---For example NV item 1877 has a default value field content of 78135687 on my Boost Desire 626S so input field is also the same but this input field is what we change.
---Click the value under input once to select it then click it again and it will be editable with the caret blinking and 78135687 highlighted.
---Type in or copy and paste the value you wish to use for the value field in this input field once it is highlighted then hit enter on the keyboard and click write in the bottom right hand side of the window to make the new value stick.
---Congrats you have changed the value for an NV item.
---After writing new values, click offline in the bottom right hand side of the nv browser and wait 5 seconds.
---You will see the signal bar on your phone go blank.
---Click reset and the signal on your phone will be restored.
---Follow these last few steps when writing new values to ensure they stick.
---Reboot your phone and the values will stick.
6 --- GETTING MSL/SPC CODE FOR YOUR PHONE
---Scroll to item ID 00085 with description security code and click it to select it then click read in the bottom right hand side of the NV browser window
---In the input and value fields you will be presented with the MSL/SPC for your phone.
---Use this MSL/SPC code to program/edit the modem nv item values in EPST menus accessed by using ##3282# in the dialer.
---Also type in spc ****** in the text field in the command bar below the view bar in the QXDM window and hit enter, the six stars being the six digits of your MSL/SPC.
---Enter the MSL/SPC in the latter manner before writing new values to the modem for safe measure to ensure they stick.
---Quick note, enter *#*#4636#*#* in the dialer to open the testing menu, and tap phone information then scroll down to set preferred network type, and tap the down arrow to the right then scroll to and tap the network type you would like to use.

I meant how do I use d softwares to edit LTE bands

Thanks a lot man. I've successfully programmed the values and although I have a Sprint version and the LTE bands are different in my country, I was able to get the values from NV calculator on play store. I've not had time to check if they work albeit I programmed 3g bands a while back and band 2100 which works in my country failed to work, I hope the LTE works. Thanks once again

Great work !!
Do you have any reference to other commands for switching the download / service modes?
To flash boot-loaders and such !!
I have the board support package for the msm8909 chipset and I am working on building the required programmers.
Just need to write my partition.xml ( I have the GPT info. )
My plan is to make a Qfil flashable Service Rom.

Update: Bands were successfully programmed as I stated earlier but sadly, they don't work. I just hope and pray someone somewhere is making a from scratch custom kernel for this device

@doyin116
Did that for Lollipop ( Completed ) For Marshmallow they didn't release the source yet.
I don't think it will be a problem to use the CAF source. ( Will Find out soon. )
Here is my kernel.
http://forum.xda-developers.com/desire-626/development/kernel-wip-port-lollipop-5-1-source-t3470476
Here's my source.
https://github.com/Bigcountry907/kernel_htc_a32eul
I just synced the CAF Android 7.0 source.
It's gonna be a wile cause I been developing this by my self but it is in the works.
I have built the UBERTC cortex a9 toolchains and compiled the kernel inline with the recovery both in omnirom 6.0 and omnirom7.0.
Omnirom 7.0 uses Ninja for building. https://ninja-build.org/
I didn't know if this would cause a problem but it didn't. None I couldn't fix anyway.
So I have used the 5.1 kernel source and built it successfully in newer android versions.
It could be the combination of ninja and the UBERTC toolchain that make it work. IDK.
What do you need in the kernel? I might have it built.

Came across your kernel but from my understanding, it was meant for the METRO PCs version of 626s while mine is the Sprint version. I also tried to downgrade from marshmallow to lollipop but wasn't successful because it seemed the tutorial again was for METRO PCs. As to what I need in the kernel, I heard Qualcomm has an anti-tamper settings or so that prevents flashed bands from working but can be by passed by a built from scratch kernel.
My questions now are: can I flash your kernel on my 626s albeit the Sprint version and if yes, how do I downgrade to 5.1 on my Sprint version. If no, could you please create a custom kernel for the Sprint version? Thanks

I got my hands on a RUU for sprint lolipop.
I will upload when I get a chance.
Right now i'm in kernel mode so you might get lucky.
Hopefully I can add the sprint config to my tree and build it.
I'm trying that with the vzw 526. So if all goes well........
After I make recovery for 526 I will compile you a kernel.

I'm glad. Is there a time frame for all of this to be done?

I will upload this ruu tonight. Over the weekend I will put together the kernel over the weekend.
You will have to test it. I don't think I can flash sprint to my device. It's metro. But I am s-off.

@doyin116n116
Here is the 5.1 ruu for sprint.
https://drive.google.com/open?id=0B8jitdIyh2NtUHQ2YWd5T2RCUFk
Download it and rename the file 0PM9IMG.zip.
See the downgrade post for metro pcs and edit the mainver in the misc partition as shown there.
You can just flash the misc.img that is posted on that thread.
Copy the 0PM9IMG.zip to your sdcard.
Boot the phone into download mode.
It will ask you if you want to install the ruu.
Hit the vol up key to install it.
If it reboots the first time back to download mode then hit vol up again.
It will flash for sure.
And don't worry.....it is easier to go back to MM than it is to go to LP.

@BigCountry907 I'm having issues flashing the misc.img. I flashed through adb fastboot flash misc.img and it said unknown partition 'misc.img' error: cannot determine image file name for 'misc.img'. I flashed through twrp and it said could not find meta-inf/com/Google/Android/update-binary in the zip file. Through adb I did adb push misc.img /sdcard/".
"adb shell"
"su"
"dd if=/sdcard/misc.img of=/dev/block/bootdevice/by-name/misc" and it succeeded but when I flashed the 5.1 ruu it said ru_zip_error.
Could it be that the downgrading process is for metro PCs/ do I have to be unrooted or can I get detailed process of flashing it if I did it wrong. Alternatively, is there a tool I can use to access the misc.img partition and edit it myself?

How do we request a moderator to do that?

Old thread on old phone, I realize... but hoping someone might catch this & assist me. Having issues with gather SPC using QXDM 03.14.594 on 626s 0PM92 - Sprint MM ROM running on I-Wireless [T-Mobile].
While attempting READ on 00085, response is: "No DIAG response received".
Concerned about programming NV values in EPST w/o it. Any thoughts?
Update: After upgrading both qxdm/qpst, I'm getting a return on read from phone. Has it possibly been set as: 000000?

When I try to start Loader Octoplus Samsung.exe - nothing happens.
According to Windows Defender, unins000.exe has Virus/Win32/Sality.AT

After Flashing the EFS file you provided, I've lost my IMEI as well.
Of course the repair network option completed successfully. But it didn't fix the no network problem. It just created one more problem and my IMEI is now generic.

Please turn off your virus gurd first

[Guide] Restore Lost IMEIs / Repair Network or Radio Issues

I accidentally restored TWRP backup of another Zuk Z2 phone on my new pgone and in this process over-wrote the EFS partition. This left me with a phone having no IMEI, no mac for Wifi and Bluetooth. Effectively No Network on phone.
Worried, I searched across internet to find out ways to restore IMEIs and get my phone working again. The way out was to restore xqcn file and use it to get back IMEIs, mac address etc. But there were various posts and mixed feedbacks. Even when I restored modified xqcn and got IMEIs back, it had only one sim actually working and other had no signal.
I spent many hours searching for finding right steps. It was a long tiring process wherein close to 2 days were gone trying multiple methods, flashing QPST roms around 10 times to observe network in Stock ROM , in Custom ROMs and after reflashing etc etc etc . Shouts go out to Akrapovic & Nordicus for their detailed posts which helped me in understanding lot many things and also finalizing key steps to restore IMEIs, MAC etc and getting phone working
Pre-requisites:
1) QPST installed on PC; Download v 2.7.453 from here or elsewhere if you know of
2) ADB / Fastboot installed
3) Drivers Installed for Zuk Z2
4) Hex Editor to edit xcqn file
5) WriteDualIMEI_W_G_eMMC - to write IMEIs once xqcn has been restored
6) Zuk Z2 rooted with ADB enabled through developer options and connected to computer
For points 2 and 5, pls refer here to download the files and tools.
So the solution which worked for me, and one which has been tried and tested is following:
1) First check the IMEIs dialing *#06#.
If you see IMEI and matching with that on your box, there is no issue and you should stop.
If you see blank / error, process further
2) The EFS is corrupt and hence we don't see IMEIs. Follow this paget and get the EFS partition wiped out to properly prepare EFS for restore of xqcn in next steps.
I had restored xqcn file without wiping EFS partition and later on had issues. But all these issues were gone when first wiped EFS and then restored xqcn. So will suggest doing same.
3) Get the xqcn for our phone Zuk Z2 from here original credits to 唐大土土 and Nordicus who shared it here
Use HexEditor to search below default values and replace them with your devices value. IMEIs / MEID is available on box. MAC can be assumed suitably
MEID: 22 22 22 22 22 22 22
IMEI1: 33 33 33 33 33 33 33 33
IMEI2: 44 44 44 44 44 44 44 44
WIFIMAC: 55 55 55 55 55 55
BTMAC: 66 66 66 66 66 66
4) To be on safer side and avoid other variabilities, it is suggested to first flash QPST rom to ensure that apart from EFS all other partitions are fine. This is optional.
5) Now with rooted phone connected to PC, open command prompt on PC and go to adb folder. From there type these commands
Code:
adb shell
su (looking at the phone screen, as during this second command you need to grant root rights)
setprop sys.usb.config diag
Once done you will see in device manager 3 new com ports are open. If some errors or no success in getting com ports opened you can try following too
Code:
adb shell
su (looking at the phone screen, as during this second command you need to grant root rights)
setprop sys.usb.config diag,rmnet,adb
setprop sys.usb.config diag,acm_smd,acm_tty,rmnet_bam,mass_storage,adb
6) In Device Manager, you will see a com port title Qualcomm Android Diagnosis etc, note the com no.
7) Open QPST, click "Add new port" and enter the port in both places (Port and Port Label), which is written in the device manager.
Next Click Start Client -> Software download. Go to Restore tab, and use the modified xqcn file which you saved in step 2 and press Start.
If any error, tick the check box "Allow phone/file ESN mismatch" and press Start
8) Once restore is 100% done, close the QPST and open the WriteDualIMEI_W_G_eMMC, and put in the IMEIs and flash. You should see Green Pass.
9) Reboot phone and dial *#06# - the IMEIs should be seen. Bingo, job done... give me thanks. Just put in SIM and network should be back.
For Step 7, if more details required, pls refer this post with step by step details
Hope this helps !! I will be extremely happy if this guide helps you in restoring IMEIs, repairing lost network and radio issues.

Yes, that will help in future. Also should take backup of xqcn file using QPST.

I had the lost IMEI problem before, but I did not need rooted phone to solve it. Just turn off the phone, then press Volume (-), and finally connect at the same time the usb cable (make sure drivers were installed before!). You will see 3 new devices, the important is the diagnostics one. Take note of the COM port, and you can use QFIL to backup/flash the qcn. All without root

I think is not EDL mode, because usb vendor and product ids are different. When I had the IMEI problem, I tried to restore qcn from EDL mode to no avail. After that, I found the suggestion of using Vol(-) and it worked, but it is a diffrent mode, because screen is not black in this one, it shows some options instead (sdcard flash, qcn restore, etc).

MEID: 22 22 22 22 22 22 22
WIFIMAC: 55 55 55 55 55 55
BTMAC: 66 66 66 66 66 66
!!! Please, notice, that Wi-Fi MAC, that you can see in menu of phone is shown as "54 55 55 55 55 55", but in editor it will be found as "55 55 55 55 55 55" and even in three places. I've changed in all three, because edition of one only doesn't change MAC after reboot.
3) Check after reboot:
- Wi-Fi and Bluetooth MACs are native
- MEID has changed, but it become upside down by group consist of 2 digits (first two digits are now in the end and so on). Problem was solved by "MEID/ESN Tool".
Press "Volume -" and "Power On/Off" (release Power after vibration) until you see "Menu from 0 to 5" (SD update...GetInfo). Connect phone to PC. Launch "MEID/ESN Tool", press "Initialize" (COM-port will be shown), then press button "MEID" and set checkbox "do MEID", enter native MEID (it is like IMEI w/o last digit; it is shown on the box and on the film from the back of the phone), press "Write".
!!! I've tried to change MEID in "MEID/ESN Tool" before QCN was edited, but this was unsuccessful, MEID didn't changed. MEID become native after I've edited QCN in hex-editor and then used "MEID/ESN Tool" as mentioned above.
4) The last one - recover native IMEIs. IMEIs were changed via programm "WriteDualIMEI(W+G_eMMC)". Press "Volume -" and "Power On/Off" (release Power after vibration) until you see "Menu from 0 to 5" (SD update...GetInfo). Connect phone to PC. Launch "WriteDualIMEI(W+G_eMMC)" and enter native IMEIs, press "Start". After reboot you will get native IMEIs.
!!! I've tried to edit IMEIs in hex-editor. But QCN include IMEIs consist of 16 digits, but regular IMEI consist of 15. I've replaced last (useless) number by pressing "space" on keyboard and after reboot there wasn't network. I've supposed that I need to put not a "space", but something like "leave an empty cell" in hex-editor. I haven't tried to do this because I have "WriteDualIMEI(W+G_eMMC)".

@sergsinger don't know why it's strange.. we can give back to xda community only by sharing our knowledge!
Since you had learnt and done it yourself, why not to share the same.

I had the lost IMEI problem before, but I did not need rooted phone to solve it. Just turn off the phone, then press Volume (-), and finally connect at the same time the usb cable (make sure drivers were installed before!). You will see 3 new devices, the important is the diagnostics one. Take note of the COM port, and you can use QFIL to backup/flash the qcn. All without root

It is shown on the box & film from the back of the phone. Usually it is like first IMEI w/o last digit.
In hex-editor MEID which comes with QCN will be simply found by typing "22 22 22 22 22 22 22" in search bar.
