[Q] N900 often can't make call/sms/browsing/chat/online game

hello.
my N900 often can't make call/sms/browsing/chat/online game while data connection (E/H/H+) was ON and signal bar full.
i try to turn off data connection, then turn it on again, the bar was full again. but it still can't make call/sms/browsing/chat/online game.
the only way to fix it is by restart the phone. i can restart my phone five to six times a day. This problem came before i installed customed rom.
anyone can help?

Redmi 3s Prime data speed dropping to E and G

Hi all,
I have bought a Redmi 3s Prime last week. One problem I am facing is that if you turn on data services, if it is idling, speed drops to E and even G. The only way to get it back is to manually change network preference type from settings. What could be the problem? Is it a hardware issue?
Android version 6.0.1
MIUI version 8.2.5.0 (MALMIDL)
Please help.

This is a known issue.
Is you have root, try to install Networl Signal Guru, then disable Edge (2g) frequencies.
Some people solve it using a second sim...

Second SIM even if dummy one will solve this problem, I'm using this option and managing my 32GB wisely as you will lose your sdcard slot. Nothing terrible for me as I need it the 2nd SIM anyways.
slds,

Your problem is well known, but still no solution from xiaomi.
Best i can suggest is that u check which frequencies your carrier uses.
If u got root, install Network Signal Guru.
Try disabling one of used WCDMA frequencies and then force 3G. if it doesnt work, try to disable the other frequencies
IT WORKED FOR ME D

Switch to global dev rom you will get the latest one. Miui 9 v 7.9.8
Better you make clean install with MiFlashTool via EDL.

How to modify LTE Carrier Aggregation and enable 256QAM/64QAM on Xperia XZ and XZs

Mostly Sony XZ-series phones have limited LTE Carrier Aggregation bands on per country / provider. You can check here more information about that: https://forum.xda-developers.com/xperia-xz/how-to/lte-carrier-aggregation-combinations-t3577544
I made step by step instruction how to modify on Sony XZ, Sony XZs, Sony XZ Premium and Sony XZ1 LTE Carrier Combinations. Rooted phone required. This instruction should working also with Dual SIM models.
Sony XZ Premium after Android 9 PIE does not work anymore
You can check this on my blog site: https://mt-tech.fi/en/modify-sony-xz-xzs-xz-premium-and-xz1-lte-a-band-combos/
Make sure you make full modem backup and backup all config files to your computer, if need restore configuration.

To try this mod, it should be supported by the carrier also! Is there a way to find out in which countries it's rolling?

Did you mean LTE Carrier Aggregation support? You just should check what band your provider support and then find possible combos on our Google sheets (link on first post).
Many providers also support well 256QAM/64QAM but not every provider yet. There is no list yet.

That's my point... There is no "list". You just try it and see if it's working. But I'm not brave enough to try it -and IF it goes smoothly- see no result because my provider being ambitious in saving money than QoS :/

That should ask from local provider customer service.
When know local LTE bands then know possible CA-combinations.

hi,
i try your LTE mod but from the last update .192 i don't have 4x F8311 (Sony XZ) undefined device, I get 3 and not MI_04. What do you think about that and how could i unlock LTE ?
thanks

Maybe you have driver already installed? Open QPST App and see your phone already added automatically?

yes it's that
Thanks you a lot

@olkitu QPST on xz1/xz premium with Android Pie works using the magisk module that you can find here: https://forum.xda-developers.com/showpost.php?p=78919730&postcount=119. No need to install custom driver, you can use the driver from windows update. I'm saying it to you also because your tutorial is among the first results on Google
Edit: It seems to not work on XZ premium. I was wrong

Thanks for sharing this! I have to put test this Magisk module and then update my blog posts.
This driver is Qualcomm official driver for Xiaomi but yes if you can find it from Windows Update that is good.

On oreo using the driver for xiaomi I had to manually insert the "COM" port, now with the drivers downloaded by windows the phone is autodetected*.
The device used by QPST is "USB\VID_05C6&PID_9091&REV_0404&MI_00". Sometimes with the module enabled the phone says "no service", to solve the problem just enable and disable the "Airplane mode", note that this does not interfere in any way with QPST/QXDM. Obviously you should disable the module after finishing the work.
And thak you very much for your work I still have some doubts about the lte_category file. Analyzing the firmware of many smartphones I understand how the files disable_cap_ies (disable 64qam/256qam capabilities), rrc_capable_plmn_list (limit the plmn that have capabilities not disabled) and the carrierpolicy works, but I found anything about lte_category :/
*In my case qpst is running in windows 7 compatibility mode

I can't get it to work on XZP Pie. Phone shows up in QPST, but as Unknown (No ESN). Same thing without the mod, but by running setprop commands from the shell. Used to work fine on Oreo.

Are you using a typec cable? Are you using the com port of the device "Qualcomm HS-USB Diagnostics 9091" ? Can you tell me if QPST see the device for few seconds during the boot?

Better buy device from France to support bands and carrier aggregation combinations used in France.

Thank you very much for your response, Olkitu. I am trying to enter qualcomm diagnostic mode, and I cannot. I have done everything you describe in your blog and nothing shows up in QPST. I even tried with the command (setprop sys.usb.config diag,adb), and I can't enter the diagnostic mode either. Do you know how to fix it? Thanks you

olkitu , little bit off topic but at what extent can be done with Qualcomm software to unlock the full potentioal of any phone? Im not talking about LTE and 5G, I mean Bluetooth, GNSS, Wifi, NFC, codecs. Because of the lack of tutorials on how to edit NV items EFS mods its a dangerous game.

Hi xavinaz.. I'm in the same situation as you. Have a docomo xz1 compact and need 20 band.
Have you found any solution ?
Right now I have Havoc 4.13 but I coudn't access the modem. But rolling back the phone to android 8 with the stock rom and using the temp root exploit you can access the modem as described in the tutorial.
But then I'm not be able to unlock the 20 band. So I go back to android 9 and now on havoc

Hello Bob, I have not been able to enable the band 20LTE. I have reviewed many blog and websites, and it is impossible.... I have not found the solution.

I know this is late but I found a solution. This requires NO ROOT and NO Mobile data. You will need a device that supports Bluetooth or Bluetooth tethering, I used my other phone. So what I did was I downloaded an app called Share it and I sent it to my Asus phone. I mainly used that app to transfer apps to my Asus since I was unable to use the internet but the solution Im about to show you, I found accidentally. So what I did was, I went on share it on my Asus phone then I clicked the Send button. I choosed the application and it then prompted me to turn on my WiFi and GPS location in order to send the file. I turned on my WiFi from the app itself and it enabled the WiFi for my phone In which I used to connect to my router. Once this app is running in the background,the WiFi will most likely stay on. I heard that once you update the phone to android 8, the issue will be fixed and I'm currently doing that to see if they were right. I'll update you right after it is finished. I might also make a separate thread about this
Update: The WiFi issue is fixed when upgrading to android 8 so use the method above to upgrade your Asus without having to pay for mobile data or root

no bro atleast thanks for reply bro:angel::angel::angel:

Oxygen OS 11 - No PDC and QPST connection

Hi,
After successful update to Android 11 on Oneplus 8 Pro, I cannot find the modem in PDC tool or QPST as before.
The device was described in Windows devices list as IN2012 without any drivers so I installed manually latest Qualcomm drivers and chose Android Modem 9020 which was recommended by some guys using beta. Unfortunately, I still cannot change modem settings via PDC.
I don't have a root on my phone and would like to stay that way.
Do you have any new guide for Android 11 how to acquire that functionality for changing modem in PDC? Thanks

Hi PDC does not detect my oneplus8 pro running android 11 .. everyone seems in this case, and no solution has been found yet
Envoyé de mon IN2023 en utilisant Tapatalk

That is true I have oneplus 8 pro IN2020, i used to have access to full-port switch and rndis,diag switch before oxygenos 11, now after updating to oxygenos 11, no longer i can access it my computer won't detect it anymore via PDC tool or QPST.

Maybe this isn't what you're talking about, but works fine here (stable 11.0.0).
*#801# to enable full-port switch.
Edit: tested PDC, also working.
Edit2: Missed that no root part. I am rooted and have engineermode enabled, that would probably be the difference.

Same for the IN2020 model that I am using.
Seems like Android 11 or OnePlus themselves are blocking the QPST port, and the only solution so far needs the device rooted.

But after using this, with root, i want to unroot and close the Bootlader ... will the changes stay in place?

Absolutely not. The only solution to relock the bootloader is to use the MSM tool. This will cause data to be erased and the bootloader to be locked. Your Oneplus will be reset to factory configuration.
