Question for anybody... I went ahead and took the chance on my Jolla phone, (Sailfish OS). No problem finding guide to access diag mode and install drivers. Followed op step-by-step, and no errors, no issues. Reboot phone, and no network connection. Sim is recognized, and network is recognized, but attempts to connect fail, (perpetual spinner). Ofono log app shows vague general messages like "... null, null, ...

I'm going to mess around some more, but wondering:

- I see that there are some device-specific instructions here; is that just for setting up, diag drivers, etc, or is there some devices that need different rv_nv value/settings? If so, what is a good way to try to figure that out?

- My main goal isn't even so much to enable global functionality, but to enable additional 3g/4g bands to be able to get 3g or 4g on my phone, which does support 3g/4g, but not compatible with the specific bands my carrier suppports. Am I totally barking up the wrong tree, or could this guide do what I'm trying to do?

- Any other ideas/input...

Thanks

Thanks
[Sony Cross-Device General] dennis5pia:
Did your phone only connect to 2G prior you followed the guide and now it doesn't?

Did you save your phone original values?
[Sony Cross-Device General] levone1:
Yes, with this carrier, only 2g, now nothing. I am not at pc now, but I left everything open, with original values in notepad. I realized I didn't save before I left, but hopefully still there...
[Sony Cross-Device General] dennis5pia:
You should have saved it. How did you calculate the bands you were adding?
[Sony Cross-Device General] levone1:
I just followed op. It said to check all gsm and wcdma.
[Sony Cross-Device General] levone1:
Info is saved, and I restored back to oruginal, and working fine again on 2g. Think there's any chance of doing what I'm trying to do?
[Sony Cross-Device General] dennis5pia:
Well, bands are hardware/software combination. If your mobile phone doesn't have the necessary hardware to work with certain band, it won't work if the band is enable in the NV.

What bands are you trying to activate and what are your device original values?
[Sony Cross-Device General] levone1:
current values are in screenshot 1; screenshot 2 shows a chart of supported bands from my carrier. I'm hoping to find a way to make 3g data work on my phone...
[Sony Cross-Device General] levone1:
Added bit 25 and 26, which seem to match up to carrier chart, bit still 2g only...
[Sony Cross-Device General] dennis5pia:
From what country is this phone?
[Sony Cross-Device General] Zacharee1:
What phone is this?
[Sony Cross-Device General] dennis5pia:
LTE bands are not supported on mzTool, you can use a NV Calculator from Google play to mess with LTE.

---------- Post added at 05:19 AM ---------- Previous post was at 05:16 AM ----------

What decimal values you set with 1877 NV field?

And what country/carrier are those bands for?
[Sony Cross-Device General] levone1:
Made in China

Jolla phone (jp-1301)

currently 844,425,130,934,400 - which is the same as in the screenshot in my last post, but with 2 others added, 'WCDMA Band I - EUROPE JAPAN & CHINA IMT 2100 band', and 'US PCS 1900 band'
[Sony Cross-Device General] dennis5pia:
I though your carrier 3G band was AWS.
[Sony Cross-Device General] levone1:
Don't know much about this stuff ... I posted a screenshot of a chart I got from their website. It doesn't say anything about AWS.
[Sony Cross-Device General] levone1:
So, I used QXDM, and a guide on XDA to enable LTE on band 2, band 4, and band 14, (the ones listed in my carrier chart as supported). Now, 2g still works the same, and when I switch preferred to 4g, it cuts in and out, trying to connect. Any ideas about that? Do you think if I disabled certain bands, maybe even the particular ones that were enabled originally, it might connect? (I'll probably try anyway, but just wondering what you think)
[Sony Cross-Device General] dennis5pia:
Yes it does, according to your screenshot, your carrier 3G band is band 4 1700/2100.

---------- Post added at 04:48 PM ---------- Previous post was at 04:45 PM ----------

I googled your device, and it seems to be from 2013, I doubt you can enable any band in it.

Next time, you can use NV Calculator from Google play, to calculate 3G and LTE bands.
[Sony Cross-Device General] levone1:
Yes, you're right... I didn't look closely last time.

Ok, thanks. Something definitely changed when I switched the lte data, but still doesn't connect - it just acts like it's trying to. Before, it would never do anything, no matter which preference setting i set...

[Sony Cross-Device General] levone1:
Do you, (or anyone), know the calculation formula for the NV items in nv calculator? I've been testing with it, but the numbers don't work in QPST. At least one of them is rejected as 'bad value' or 'bad parameter'. Usually either 0441 or 0946. I think I've tried every possible combination of bands, and it always rejects either one or the other. I've read some posts questioning it's accuracy. Is there a way to manually calculate?
[Sony Cross-Device General] dennis5pia:
You can use MzTool too. But I think that only 1877 has to be set anyway. Check if QPST is using decimal or binary.

The calculation is, 1 if the band would be on and 0 if the band would be off, then you gonna have a binary number

hello guys,

so i just enabled band 40 in my note 3 (N9005). band 40 is there "B40: TDD 2300"

i locked it using network signal guru app to band 40, so that it can only use band 40. but it is not getting any type of signal.

what should i do now. should i disable any other LTE band, so that B40 can work ??

additionally there were some settings related to VOIP in NvBrowser. they were all "0", so as disabled. I enabled them ALL. any info on this is appreciated. voip is volte ? right ?

i am on aryamod note 7 port 2.1 android 6.0.1

[Sony Cross-Device General] palmbeach05:
Actually i think its more along the lines of why do we old schoolers still get out for the daily grind but the noob generation wants all the answers without putting in the grunt work.

[Sony Cross-Device General] x2bc4:
I guess in part it's because of manufacturers enforcing restrictions on recent devices and the lack of information on how to circumvent those restrictions. They started to take a lot of measures to avoid people modifying their phones.

I have a SMG note 3 (n9006) this model is from china and have 2 LTE bands (band 4 and 13) but these bands are not available in my country so I can't pick up 4G with this phone! So I want to ask you if there is a tweak or flashable file which can permit me to have LTE band of Samsung n9005 ( band 3 or band 20)because these bands work perfectly in my country

I try ti edit nv but i faild can you help me

I tried to edit nv but i faild
[Sony Cross-Device General] palmbeach05:
You can always find the firmware from another country that has the note 3 working on those bands and flash that modem to your device. I haven't messed with the method in this thread since 2015, so idk how it works now
[Sony Cross-Device General] Rvrjei:
If i do this, can i get my device GSM Network Unlocked? I mean, use it in another carrier?

Unlock bands and test with a sim from the desired carrier prior to purchasing a plan. Best advice.

No. It doesn't unlock sim card, but bands.

Quick question, just modified some of the NV memory on a dual sim phone (Xiaomi MI5S) , and in result my first sim does not work anymore (found out almost a year later when trying out two sims at once).

Stupidly enough cannot find the backup I made before editing.

Trying to figure out if this is reversible damage or hardware damage: I've tried flashing stock firmware, stock rom, but the issue didn't change: Sim 1 has an IMEI in the settings, but no other sim info can be seen.

However, does this actually change the NV configuration, or is this memory only editable using QXDM, and is otherwise factory-set/not affected by firmware/rom installs?

[Sony Cross-Device General] tonyM_75:
Hello everyone,

I want to activate LTE900MHz (Band-8) on Sony LT25i (Qualcomm MSM8960). This LTE-band isn't found in standard configuration. But Band-8 is found in standard configuration for GSM and WCDMA.

I have TEMS-phone of this model (Android.4.0.4, ver.9.0.1.D.0.10-TEMS).

The phone was rooted successfully by towelroot, installed SuperSU. Qualcomm drivers installed: in Diag-Mode LT25i detects as several USB-devices (diag, modem, serial, adb) with VID_0FCE&PID_5146, and drivers found at LT18i-driver pack.

Diag-port (USB-dev=VID_0FCE&PID_5146&MI_04) activated:

adb shell

su

setprop persist.usb.eng 1

But QPST can't find any phone behind diag-port. I tried everiting, but without success: port is open/visible, but no active phone at this port.

I don't know what is the problem with diag-port:

- drivers

- forbidden access to modem at TEMS-firmware

With modem, found as USB-dev=VID_0FCE&PID_5146&MI_02, no problem with communication (WindowsDeviceManager->ModemProperties->Diagnostics->QueryModem).

I don't have standard LT25i to check.

I checked on standard LT18i (ArcS) and standard D2303 (M2)- they are visible by QPST through diag-port (NV-memory is accessed).

Do you have experience on this topic ? Any ideas/help how to access NV-memory in order to change LTE bands ?

Regards,
[Sony Cross-Device General] tonyM_75:
I just found, that probably the process "tems-server" intercepts the DIAG port.

When I kill the process "/system/bin/tems-server", it appears again with new PID.

Attached you can find this file (and some other files from /system/bin/, which I found useful).

Also the root processes and listing of /system/bin/.

What you can suggest as next step?
[Sony Cross-Device General] tonyM_75:
I get the same info from my stock Xperia M2 (D2303, MSM8926)- see attachment.

And I think that immortal process "tems-server" is a kernel-one.

If it couldn't be stopped, may be I have to flash stock kernel in order to have DIAG-port working. What do you think?

[Sony Cross-Device General] Androidonis:
Hello everybody. I got a refurbished Z3Compact from China. It reports as D5803, but only LTE 1,3,19,21 supported. It seems that it can also receive 20, maybe because it is very similar to 19. But reception is always at minimum strength. Will it be possible with this method to activate B20 and use it better?
[Sony Cross-Device General] dennis5pia:
If you got reception on B20 even with poor signal it means B20 is activated within your device, so the poor signal issue is something else.

Enabling bands with this method is not guarantee and it can damage your modem leaving your device with no reception at all.

Hey guys in own an LG V50 ThinQ with model SKT_KR on GSMarena I see a LTE support for 3 and 8 the reason I got the phone and I noticed LG enforces some support of carrier restrictions (don't know if the Korean variant applies too) I've been tryna get band 3 and 8 working but to no avail I need this for VOLTE was wondering if this could help me
[Sony Cross-Device General] maryo_mariux:
Hi All,

I have a Xiaomi Mi10s and I want to unlock LTE B20. Following some tutorials from internet, I managed to Root the phone, to put it in diag mode, to be accessible by Qualcomm Product Configuration Assistant Tool and also QPST and try to modify the NV values. Some values can be accessed and some others not.

To put the phone in diag mode i used the following commands:

adb shell

su

setprop sys.usb.config diag,adb

or

adb shell

su

setprop persist.vendor.usb.config diag,diag_mdm,qdss,qdss_mdm,serial_cdev,dpl,rmnet,adb

setprop sys.usb.config diag,diag_mdm,qdss,qdss_mdm,serial_cdev,dpl,rmnet,adb

After the commands were entered, SDX55M was recognized and accessible.

I was trying to read exactly the value LTE 6828 or 6829 and it says NVITEM INACTIVE.

Other NV Items for example MCS 67295 it says NVITEM READ COMPLETED and it can be accessed.

I also managed to access NV/EFS config tool straight from Rueban (MTB)V2.4 using secret code explorer app accessing 663368378.

I believe that using this tool i can edit the NV Memory values without Qualcomm Product Configuration Assistant Tool and also QPST.

Kindly advise how to unlock band b20 because I am not sure if this method of changing the NV values 6828 or 6829 can still be applied to unlock LTE Bands.

Thank you,

download the file from #1, unzip it and open htcdiagdriver folder, choose x64 and open htc.....inf using notepad or notepad++ and change the ids according to your device.... @all I'm tired of the question like "Can it works on xxx?". The simply answer is: Try it, change the driver to use with your device, and play with it. Not just with QPST configuration, also service programming, EFSEditior, bla bla bla. You can play with gps, display, sound, wifi, all of the setting in your phone that's hardcode on software.....

Yes, by allowing non-signed drivers

No, it is okay, the only strange behavior is the connecting and reconnecting sound from windows.

I have run both of these together. Had real slow downs with WAD, Phone Alarm and several other Desktop stuff on one Desktop. But using WAD allows multiple desktops so in the end I only put one heavy memory app on each desktop and it worked fairly well with little slow down except on the desktop with Phone Alarm. Now I do not run Phone Alarm (too many slow downs) but I would not live without WAD. There are those around though that say Phone Alarm is only slow if you have not gone into all the menu items setting them up just right for the device, so I'm prepared to believe it wasn't slow, I was!!!

[Galaxy Note II Q&A, Help & Troubleshooting] soleil0524:
I have a sprint galaxy note 2 lte 4g. I needed to get it to work for pageplus, so i did everything needed and got it working. I decided to try and install a new rom so i could get rid of the sprint activation screen. So i downloaded the rom and cleared cache and reset in recovery mode. Now I am stuck on the bootscreen. I tried about 15 different roms and they are all the same. Either i have a bootloop or it just sits at the bootscreen. I was told from a friend that i am probably installing roms for the wrong build, but i dont know my build. I didnt do a back up( i know that was stupid of me). So all i know is that my phone is Sph-L900 because that is what it says under the battery. If any one could help me i really would appreciate it. Like i said i tried so many roms and they installed fine via recovery but wont go to homescreen, i already searched for hours on this and nothing is working. thank you ahead of time to everyone
