Where I can get this app "Network"?

Some of those steps are placebo, and unnecessary. That will only get you 1x internet, and dependent on your location you may/may never get 3g to work they've been blocking off more cities from flashed phones from getting 3g..

Lenovo Vibe Shot z90-7 unlock radio bands and improve signal strength

So this is tutorial that i'm putting together after i bricked the signal of my phone. It took me week of digging and learning of usb debugging tens of posts read and I managed to repair it plus additionally unblock various regions in radio settings menu (*#*#4636#*#*).
I should mention that there is no warranty on anything I'm about to write
Step by step:
1) phone has to be rooted and has superSu so flash it with appropriate rom
2) download and install following:
https://mega.nz/#F!RA83UTjA!M4v2djifO27mcL1OSzO9Ew
3) Download and install android SDK package
4) set your phone to USB debugging
5) on your PS go to \Users\(your user name)\AppData\Local\Android\sdk\platform-tools
hold SHIFT+right click--->Open command window here
Have your phones screen on and type in command window on your PC :
adb shell (enter)
su (phone will ask to grant permission)
setprop sys.usb.config diag (enter)
6) Go to device menager--->COM Ports-->Hs lenovo diadnostic click properties and change driver to the one you downloaded. It should come as HTC diagnostic
7) open QXDM Professional (you downloaded) go to Options-->Communication-->target port. Now set the COM port where your phone is installed. Go back to the main window and from "View" dropdown menu select "NV Browser".
8) You will now locate following lines and change their values to the one i provide(remember to backup original values).
8a) Select dual sim and remember to change settings for both sims "subsciption" first 0 then 1
Select item hit "Read" change the value then hit "write":
441: 0x380
946: 0x0FFF
1877: 1970325105345408
2954: 0
6828: 1904863 (experimental LTE band unlock)
You might have some values already on your phone...I messed mine in the first place so I'm not sure which ones are original
9) go to your phone deselect USB debugging then restart now you should have additional menu to change band settings in *#*#4636#*#* phone info.
10) to improve signal strenght edit build.prop on your phone located in /root/system
find line "ro.ril.hsxpa=1" and change the value to 2 then start adding lines as follows:
ro.ril.enable.dtm=0
ro.ril.gprsclass=10
ro.ril.hep=0
ro.ril.enable.3g.prefix=1
ro.ril.hsdpa.category=8
ro.ril.hsupa.category=6
ro.ril.enable.a53=1
Some of it might not work for specific countries/carriers so just experiment

how to root it for z90a40 / international firmware?

Hello Fucpl , you're more able to unlock the band 800 LTE ? I tried to change some items in NVRAM but without success.
It seems instead thah in the Czech model lte 800 functions properly . Look below
Bye!

Hello Fucpl , the guide I tried as well but without result . I think the problem lies in the modem firmware , which probably does not include the band 800 as not used in China . The solution would be to flash the modem of the Czech rom , but we have to find it

Anybody tried this?

There should be a phone software backup in QPST. I havent tried it but this might be a way of ripping the czech rom. Would be nice to try it out....Out of the box question- how is a reception on your vibe shot? Mine is constantly fluctuating in one minute, same spot i can have full bars and then suddenly drops to 1 or none and then call quality becomes rough and choppy.

does this guide really work?
I'm trying to use LTE on 2600 mhz in canada and I am not sure if my phone is on a different LTE band or what.
Has anyone else had success with this guide?

Points 1-5 worked fine, but now at driver changing i have a problem. there is a HS Lenovo but i could not change it to HTC diagnostic, how could i force this win7 64-Bit? Tried to search in folder and picked file manually. Thanks for your help.
edit: think i left test mode after flashing i'll try later again
edit2: tried again, Win 7 64-Bit is still in Testmode but no chance to change the driver to HTC. Win always says driver is already uptodate.
Any idea how i could manage this problem in another way?
i found out some codes for Vibe shot:
*#*#8363#*#* select SGLTE+G/DSDA aso.
*#*#333583#*#* FDD-LTE enable
with these FDD could be enabled and some settings of the band also - but no chance to bring me a working cell back...
Any ideas? Maybe could anybody try these codes and give me the settings?

I'm stuck at the first step! How do you root this phone?? Please help =(

i found an easy way to fix broken radio after *#*#4636#*#* and Band set to USA-Band.
Do the points like fucpl wrote to point "adb shell" and "su"

hold SHIFT+right click--->Open command window here
Have your phones screen on and type in command window on your PC :

Click to expand...
Click to collapse
Then enter:
1. Start background prozess to sdm0:
cat /dev/smd0 &
2. Have a look at your band settings:
echo -e 'AT$QCBANDPREF?\r' > /dev/smd0
my settings were wrong:
$QCBANDPREF:
"24.GSM_850"
"26.GSM_PCS_1900"
"28.WCDMA_II_PCS_1900"
"31.WCDMA_V_850"
3. Change the settings (have a look at the list, DO NOT take this settings "8,9"):
echo -e 'AT$QCBANDPREF=1,"8,9"\r' > /dev/smd0
("8,9" are the settings from the list, this command writes directly
to NVRAM, so you don't have to do anything else after that)
4. Then "OK" should appear:
[email protected]_row:/ # AT$QCBANDPREF=1,"8,9"
OK
5. if nothing appears in terminal you could hit "Return".
Your Lenovo Z90-7 should now be back with connection and your settings.
to test just enter:
echo -e 'AT$QCBANDPREF?\r' > /dev/smd0
$QCBANDPREF:
"8.GSM_DCS_1800"
"9.GSM_EGSM_900"
Have fun
This was tested with S208 ROOT.
Maybe we have a chance to activate Band 20 with AT commands. I'll check this out these days.
The mainreason for this was fixing my broken radioband
Another example, this command sets the following Bands:
[email protected]_row:/ # AT$QCBANDPREF=1,"8,9,10,24,25,26,27,28,31,34,38,43"
OK
AT$QCBANDPREF?

lenovo network problem
hi everyone,
i am a new member i signed up to get spme advice. few weeks ago i bought a lenovo vibe shot which had a rom with baidu and the other rubbish installed and to get rid of them i flashed the 5.1 rom successfully. However i was not happy with the strength of signals it was getting and i tried some things i found on this website to unlock radio bands. unfortunately i was not successful with that and now it does not make or receive call. it shows one max two bars network and still shows the name t-mobile which is wrong from the beginning as it should show ee because im on 4g. but the calls not connecting for some reason. i tried following the steps mentioned here but because i am just simply not good enough to solve the issue. well, would anyone be so kind and write the procedure down in the simplest the very simplest way to a beginner? please i would appreciate the help. i would love to use the phone again as it is much nicer then my moto x 2nd. just one more thing is the a chance a marshmallow update is out for the vibe shot? thanks again and sorry for the trouble

Did you try the above version with AT commands?
You need Root S208 and Terminal app from google play,
it is the minimum

Is there a way to unlock 5.1.1. OH1?

I already have root and have tried idones app to unlock, but for some reason, the unlock seems not to be working. The app says the phone is unlocked but when I insert a GSM sim card into the phone, it doesn't get any signal and the hands free activation loops. I was advised to go into settings -> mobile networks -> GSM, but the mobile networks setting disappears when I put in a GSM sim. It comes back if I put my Sprint sim is put back in. I also select GSM on that while my Sprint sim is in but when I take it out, that menu disappears. Is my phone unlocked or is it still locked? If its still locked, what steps can I take to unlock it given my current build and android version?

Idone should b able to help . Go to dialer, dial *#0011# ,
then in service mode press menu > back , then press menu > key input and type "Q" and press enter.
Then press menu > key input and type "0000" thats zero , 4 times .
The rest im copy n pasting from "jayfi" post iver at the us cellular forum
* - UE Settings & Info
- Settings
- Protocol
- NAS
- Network Control
- Band Selection
* Make these selections above
* *Make sure you use the more button in the upper right corner to go back if needed(Back Key on phone will exit menu)
* Choose choice 7 “LTE/GSM MODE ONLY”
* Reboot
* Go to settings/Wireless & networks/more and it will allow you to add the correct APN
* Change preferred network type to LTE
Let me know if you need clarification. I don’t have the phone in front of me currently but am pretty certain that is everything.
^^ after ding this itll go straigbg to gsm connection and bypass the cdma network. Let me know if you need help.

I have done all the steps up to 0000
After all those steps, the Service Mode Menu still looks the same, how do I get to the "UE Settings and Info"? It's not in my settings menu

Sent you a shortcut in pm . Let me know if u need help .

Can this work for the l720

Fix for VS986 dropping down from 4G LTE to 3G/H+

I've been working on a fix since a long time now. If you are in SD community then you prolly know me. Anyway I was able to fix this on two of my phones and it's now working fine. I tested for 12 hours now. I'll also tell you in the end what problems I'm seeing. I'm also working on a fix for that.
I noticed that a service is started when the fallback happens but if I kill that service the network also dies. But if you follow the below method it safely starts a new service which kills the one that's responsible for killing the 4G/LTE
1. Upgrade your phone to 13B firmware
2. Root 13B
3. Now download Shortcut Master lite app from play store.
4. Now add these shortcuts to your favorites in the "Shortcut Master lite app". You can search for "LTE" and click on search button
LTEBandSelection
LTETestMain
LTE System Selection
CDMAPreference
5. Now click on "LTEBandSelection" and enable all the bands
6. Save and reboot
7. You now need to enable your data and turn off your wifi. Make sure your phone is in Global mode (in settings >> Mobile networks >> System select)
8. After your phone is rebooted open "Shortcut Master lite" app.
9. Now tap on LTETestMain
10. Select Click on CDMA preference.
Now choose Band preference and select "any"
P_REV_Preference ---> "MOB_P_REV 3
This is important.. EVDO Revision --> Rev A
11. "LTE Connect w/o IMS PDN" must be checked
12. Now go back to your main menu in shortcut master lit app
13. This step is very important. Changing the timeout is important. Tap on LTE System Selection
Except "Scan duration" add a couple zeros to all the other timers. For eg: T_mpsr timer (Min) is 200
The fallback timer will reset itself after reboot. But don't worry the configuration is already updated with the new value. For some reasons the shortcut master lite app is not picking it up.
14. Now finally click on "CDMA preference" in the main menu and make sure it has the value you set in Step 10
At step 10 or 13 your network should go away and your phone should complain about "no network". That's fine. just ignore the message.
Now finally reboot your phone. That's it. You should now have 4G LTE and it won't fallback to 3G or H+
The only problem is when I'm on a call my 4G LTE is dropped to 3G/H+. But after I hang up it goes back to 4G LTE after 12 seconds. I don't know if it's an expected behavior. But I'm trying to see if there is a fix for that.
I tested this with Tmobile. Make sure your APN settings are correct.

Thanks @motorhead_biker., you rock!!!
I am on rooted 11a, flashing stock back and then will go to 13b to try this out. Was waiting for this.....

Isn't this thread a duplicate of http://forum.xda-developers.com/verizon-g4/general/guide-fix-vs986-dropping-to-3g-h-4g-lte-t3272434? Can they be consolidated?

Thread closed as there is already a copy in General and that is where it belongs.

Unlock network bands, enable voLTE and 5G on nonsupported countries

Hi,
Other phone models can use EFS Tool, QPST tool to do all the mentioned tasks.
And some phones to do that requires rooting phone since they dont have Engineering mode, and some with Engineering mode support doesnt need rooting to use the mentioned tools for example OnePlus phone.
So my question, does LG phone also has this thing called Engineering mode? since LG wing is not supported for bootloader unlocking by LG yet.
Anyone has more experience with LG phone and perhaps the mentioned tool can shed some lights on the concern? Thanks.

Goid app. Well made

on LM-F100EMW,
1) use dialer code #*462633*#100#
2) go to Field Test > LTE Data Test > Tethering Mode, and select QMICM
3) go all the way back to first menu and go to SVC Menu> Port Check Test> Port Check Test and select enable
after that I am able to connect QPST. I used EFS explorer to fix CA-combos and carrier policy for my region/provider.
After doing your work, revert the changes to have a regular USB connection!!

for VOLTE first try to
1) make a new file or folder with name "enable_ue" (without quotes) on your phone's internal storage.
2) use dialer code #*462633*#100#
3) go to Field Test> Universal Enabler > Create New Config , enable VoLTE and confirm.
to add VOLTE indicator next to battery and signal strength on notification bar
1) use dialer code #*462633*#100#
2) go to Field Test > GPRI VoLTE/VoWiFi > IMS> select Sim Slot > Registration > VoLTE > and enable VoLTE Indication.
after all these
1) use dialer code #*462633*#100#
2) go to Field Test> IMS Settings> select Sim Slot > Test > Restart IMS process > select Yes
now you should have VoLTE enabled with notification bar indication

This is a good write up!Thanks for this!But,what modifications are you making in EFS Explorer to fix CA-combos and the carrier policies?I have a T-Mobile branded Wing,and I'm trying to enable VoLTE AND VoWifi for AT&T since this 3g shutdown went in effect?Mostly conerned with the VoLTE part because I can't make voice calls without it.Thanks for your help.

For volte i didnt change anything from EFS.
The changes i did in EFS was to add 5G for any carrier, because my carrier was not supported, and also to take the CA string from another phone's firmware, that my carrier has good support, and paste it where the outdated ca string was inside my wing's EFS.

I'm on T-Mobile firmware,and I have tried and no go.If you extract modem_a or modem_b from the firmware it has all the carriers listed.

Hi. I have LG wing unlocked dual sim. But not getting volte. Tried the hidden menu option. It is showing in settings but looks ims not registered. Can you tell if you were able to get Volte on LG Wing without mbn loading. Also if mbn loading is needed, what is the process and where do you find the files for LG wing Malaysia carriers that I can use. I have another Samsung phone and that is fully volte supported. Can I copy something from it?

Hi,
Other phone models can use EFS Tool, QPST tool to do all the mentioned tasks.
And some phones to do that requires rooting phone since they dont have Engineering mode, and some with Engineering mode support doesnt need rooting to use the mentioned tools for example OnePlus phone.
So my question, does LG phone also has this thing called Engineering mode? since LG wing is not supported for bootloader unlocking by LG yet.
Anyone has more experience with LG phone and perhaps the mentioned tool can shed some lights on the concern? Thanks.

for VOLTE first try to
1) make a new file or folder with name "enable_ue" (without quotes) on your phone's internal storage.
2) use dialer code #*462633*#100#
3) go to Field Test> Universal Enabler > Create New Config , enable VoLTE and confirm.
to add VOLTE indicator next to battery and signal strength on notification bar
1) use dialer code #*462633*#100#
2) go to Field Test > GPRI VoLTE/VoWiFi > IMS> select Sim Slot > Registration > VoLTE > and enable VoLTE Indication.
after all these
1) use dialer code #*462633*#100#
2) go to Field Test> IMS Settings> select Sim Slot > Test > Restart IMS process > select Yes
now you should have VoLTE enabled with notification bar indication

When i go to field test and click on ims settings it is showing not supported. I formated my phone and it became like this. Before formatting it used to work and I could see ims settings. My phone I bought from a shop and the shop keeper sent it rooted. Thatd when IMS settings were working..but after I did a reset saying not supported. How to bring it back?

Where are you located and what condition is your phone in? I've got an AT&T branded phone but I'm on TMO...maybe we can switch!

When I go to field menu in my Lg Wing, I go to IMS settings, it is completely blank. Someone please help me in registering the Volte in my Lg Wing. I am already rooted by able to patch the stock boot.img using magisk. My phone came with an unlocked bootloader and its the European firmware. I am trying to use this phone in Asia (Malaysia). Surprisingly, when I got the phone from the seller, it was not enabled volte but IMS settings in field menu would also show up (unlike now when I go there and it is blank), and also surprisingly, my volte worked also but by mistake I formatted my phone and after that it never worked. I then tried to flash the stock firmware and did root, installed voenabler but nothing seems to be helping.
I even tried loading mbn files of different carriers via PDC but no help. IMS settings always stay blank and volte doesn't get activated. Such a good phone but not able to work because my carrier here only supports volte.
If someone has an interest in helping, will be great.
