[NEED HELP] KATE Device but need to use KENZO modem - Xiaomi Redmi Note 3 Questions & Answers

[NEED HELP] KATE Device but need to use KENZO modem - Xiaomi Redmi Note 3 Questions & Answers

Hi all
Im owning Kate device, certified by xiaomi it a KATE device as i check online by IMEI and SN
However when i flash official miui for Kate through EDL method, 'clean all', my phone will have signal issue, i check inside settings, the radio service is not turning on, IMEI still intact, Simcard is detected however still no signal
I need to fix it by flashing KENZO modem or kenzo rom to fix the issue.
May i know how to fix this
is it gonna be an issue if im using kate but flash kenzo rom/modem , as for my checking there some issue with 4g turn to 3g frequently. :crying:

Would not advise it, "kenzo" modem firmware has drivers for other sensors than just the connectivity, ie fingerprint etc.
I would advise to search for another solution if possible for your problem. Maybe check the APN settings are correct for your provider!

added apn setting as suggested by telco, still the same no line
in Kate modem/rom if i accces #*#*4636$#*#* i can see radio signal is turn off. cannot turn on even press and wait many times
if i flash kenzo modem, i can set on and off the signal.
anyone know any related fix.

No Mobile Network Connection

Hi;
actually I´m having an issue with a Kenzo device.
If unlocked the bootloader (unoffically), flashed TWRP and Ressurrection Nougat. With this ROM I did not get a GPS fix or Mobile Network Connection. SIMs were detected and PIN coud be entered.
I went back to Stock Marshmallow and lost baseband and IMEI but I could recover it by installing modems and IMEI.
GPS is working now (but not with CM based ROMs), SIM is detected but there is no connection to Network: Wifi is working fine. Manual and automatic search for Networks are not working?

I think you need to unlock it unofficially using MIUI8, are you unlocking via flashing MIUI7?
http://en.miui.com/thread-345728-1-1.html

unofficially. But I guess I have just found the problem. It´s not Kenzo but Kate. How can I fix this?

Radio off. No service. But sim is detected. Help needed

I had been using RR ROM. After flashing back to miui lost IMEI. It was recovered back by restoring with qpst. But now it shows the sim to be detected and there is no signal coming. I checked phone information *#*#4636#*#* and it shows that radio is off . When I try to turn it on it doesn't. Also the phone shows to be in airplane mode when I try to make a call.Even though when I checked the settings it is not in airplane mode. Could anyone help me out with this?

Extract non-hlos from official rom and flash it in fastboot mode using adb

is your imei turn back? try to restart modem using dfs ..

i own redmi note 3 3gb 32gb KATE device, having the same radio turn off issue
my fix is i flash modem from kenzo into my kate, you can try that vice versa.

[GUIDE] Restore baseband - K6 Note - when no IMEI/no outgoing calls/WiFi or BT issues

Hi all,
I just wanted to share what I did when I had a few problems with my Lenovo K6 Note - karatep.
What did I do which ruined my phone?
I unlocked my bootloader, still on stock ROM, haven't installed TWRP yet.
Since then no calls on non-VoLTE network like Vodafone/Airtel/BSNL.
Primary SIM doesn't connect to any other network than 4G.
I had installed CM15.1 ROM with TWRP and Magisk root and I had the same network issues.
When should you follow this guide?
You have problems with network connectivity where you can't make calls on 3G or 2G network.
Primary (data) slot doesn't connect to 3G or 2G.
No signal on either one slot or both the slots.
IMEI shown as null or 0.
WiFi and Bluetooth address either different or shown as unavailable.
Rebooting to fastboot and performing "fastboot erase modemst1; fastboot erase modemst2" didn't work for you and lost your IMEI and/or WiFi and Bluetooth address.
Do not reboot to fastboot and execute "fastboot erase modemst1; fastboot erase modemst2". I lost my IMEI and MAC because of this.
Requirements:
1. Your phone needs to have root access.
2. Your original IMEI numbers and WiFi address, you can find them from your phone's packaging box.
If you don't have your IMEI, better use an IMEI from an old/dead phone of yours. Don't google this up, there can be blacklisted IMEIs.
Steps:
Preparing the .QCN file for restoration
Download and install UltraEdit (you can google up this for the link)
Download and install Qualcomm QPST/QFIL downloader (google it again)
Download IMEI Converter (find it in the attachments below)
Download .QCN file (find it in attachments, this is for Lenovo K6 Note - karatep)
Get your IMEI (for both the slots), WiFi and Bluetooth addresses
Open IMEI Converter and type your IMEI. You will get the hexcode for your IMEI, get the hexcode for both of your IMEIs. Copy the hexcodes.
Open the .QCN file with UltraEdit and search for "08 8A 11 11 11 11 11 11 11" (without the quotes). This is the dummy IMEI in the file, you have to replace it with your phone's IMEI.
In UltraEdit, goto find and replace, search for 08 8A 11 11 11 11 11 11 11 and replace it with your IMEI's hexcode. You have to replace the first hexcode with the hexcode for your second slot's IMEI and the second hexcode with the hexcode for your first slot's IMEI.
Search for AA AA AA AA AA AA and replace it with your WiFi MAC address, this has to update your Bluetooth address as well, there are four places where you have to replace it with your WiFi MAC address.
Save the .QCN file and close UltraEdit.
Enabling DIAG COM port on your phone to download .QCN to your phone
Execute in command prompt.
adb shell
su
setprop sys.usb.config diag,adb
Click to expand...
Click to collapse
This will enable the diagnostic port on your phone.
Restoring .QCN to your phone
Open QFIL as administrator.
Connect your phone to your computer, keep your phone powered on with DIAG port enabled.
Goto Tools -> QCN Backup Restore
Browse your edited .QCN file
Don't change SPC code - leave it as such.
Select Enable Multi-SIM.
Click on Restore QCN.
This will take some time, once done, restart your phone.
Voila! Your IMEI, WiFi and Bluetooth addresses should be updated and network should be able to receive signal and place calls.
Please feel free to reach me if you run into any issues, I'll try my best to help you!
Thanks,
tfr!

No it will not. Flashing stock firmware even with QFIL will not fix baseband issue.

Hello,
Sorry for the late reply, we have a bad network connection here due to the lockdown.
Coming to your problem, karatep simply refers to K6 Note, so you have done the right procedure hopefully.
Can you see the IMEI when you enter *#06# in the Dialer?
You're on stock ROM right? Where did you get it from? You did a full flash with QFIL or a ROM flash only? Please note that ROM flashes can be dirty.
If you can see your IMEI, please try the following in the order I've mentioned below.
1. Check the network settings and select the proper network type. Especially if you are on Jio, set it to LTE only, make sure that the non-Jio SIM is set to GSM only. This is the most common problem.
2. Perform a full system reset from recovery, must solve the problem usually.
3. Try lineage 15.1 or 16.0, you'll be able to find the links here, they are really stable and worth upgrading.
4. Full factory flash with QFIL, you should be able to find videos on YouTube, else let me know, I'll be happy to help!
Let me know the results.
Happy to help!

Thank you for the reply,
i do see my imei when i enter the code, Its the sn number that has been changed..
and about the stock rom part, I didn't do it by myself, i had given the phone to a repair shop earlier to fix the issue, this was before i flashed the QCN myself,
i flashed the qcn from a youtube video and all that guy had told was to have stock rom marshmallow, the repair shop had flashed a marshmallow rom so i figured it would do.. but i dont know what tool they used to flash it..
i used QFIL to flash the QCN though..
Let me try the factory reset solution and if that dont work i ll try to flash stock rom again...
for the other two,
1. The network settings are inaccessible for me(i tried to attach screenshots but its asking for URLs)
3. I really dont want to use lineage OS if i dont have to..
let me try the other solutions and i ll let you know..
thank you so much for helping me..

Hello,
You cannot do anything about the serial number, there is currently no way to restore it, it should not limit the functionality of the device.
Is your phone rooted now? Do you have TWRP installed? Try resetting the phone from TWRP. If it doesn't work, restore stock rom with QFIL. Restoring with QFIL will reprogram your eMMC chip and revert it to stock, TWRP will be removed. This will give you the cleanest possible install.
For flashing QCN, you don't need stock Marshmallow. I'm on Lineage 16.0 and I keep changing my MAC address with QFIL, that is not a problem at all.
I'd like to see the screenshots, you can add them as attachments... Use the paper clip icon above, else upload the image to Google Drive and put the URL here.
Happy to help!

And no my phone is not rooted and nor is TWRP installed..i was planning on rooting it as a last resort..
I m now currently downloading the stock rom file..its nearly completed..

You don't have to root if you're flashing with QFIL.
How did you flash the QCN without root anyways?
Again, what network are you in?

i followed this youtube video..
https://www.youtube.com/watch?v=1-4tmWvTGiI
i remember reading about it somewhere.. you only need to enable diagnostic mode to flash QCN, and many phones require root to enable this port, and some other need root to unlock to bootloader..
but k53a48 phones have unlocked bootloader and diagnostic mode port can be enabled easily like the guy in the youtube video..
(power off and press power button and volume up till a screen comes on and then connecting the USB, the PC installs the diagnostic port..
this is what i think happened.. i had zero errors during qcn flashing and i hope i didn't do it wrong?
I Have idea network if that is what you asked
The ROM download is complete..so i ll start flashing then?

It's correct that you have to enable only the diagnostic port to download QCN, but I'm not sure of the procedure that you describe here....
K6 Note doesn't come with an unlocked bootloader by default, you'll have to manually unlock.
I'm not sure of the technique that is shown in the video, the general procedure to open the diagnostic port is through adb. But if you are sure that the IMEI is flashed correctly, then there's nothing to worry about I guess.
Again, you're going to flash the S223 ROM using QFIL right?
Your network is fine, it's non-VoLTE, so calls should work if you have restored the QCN properly.

I m downloading the rom from a link in the description of a video..there were multiple stock files and i asked the youtuber and he told me download this one..
Lenovo_K6_Note_K53A48_K53_USR_S306_1709051329_Q00440_POLK_QPST
This is the one that i downloaded.. why are there so many stock files anyway? Is this right? Else
Would flashing stock using lenovo moto assistant application work?
Some people in xda had success using lenovo moto assistant..but the application asks for HW code and I cannot find my HW code from my sn number- HNB1GDX3 ,
No calls are not working, even ussd codes arent working..does that mean that even the qcn flash was done wrong ?:crying:

Hello,
The file seems to be correct. You should install QPST and use it to flash the ROM file.
Lenovo moto assistant might work, I had no success with that though.
The QCN that you used might be probably dirty, I'd suggest you to reflash with QPST and try burning the QCN again. Generate a new QCN before you do.

Sir, I Did custom ROM flash for lenovo K6 note, with twrp and lineage OS 16, after completion of ROM flash, although I have IMEI number, wifi MAC address in about phone section
My problems to FIX:
------------------------
1) Need Volte support(VOLTE not supporting for my JIO SIM)
2) *#06# IMEI code not working(IT shows "Connection problem or invalid MMI code." although the IMEI numbers are available in About phone category under settings)
3) In settings Bluetooth address "Unavailable"

Hey FayazD,
What you've mentioned seems to be a common problem and I couldn't really find a fix.
1). VoLTE doesn't seem to work. Before writing this post (restoring the baseband), no other calls except VoLTE ones worked for me. After restoring the baseband, 3G/2G calls work and VoLTE doesn't work. I'm not sure if there is a fix for that.
2). This could probably be an issue with the ROM itself. Try to flash a different ROM, I recommend AEX, which I'm currently using and is very stable.
3). The Bluetooth address issue again is something which I observed in Lineage 16. It shouldn't affect the functionality, except for the changing Bluetooth address on every reboot. Not sure if it is an issue with the ROM itself, try AEX, this issue isn't present there. Again note that the Bluetooth address could be shown as "Unavailable" when Bluetooth is turned off.
Will update if there is a solution for the VoLTE thingy.

In AEX the VOLTE will work or not, if you give me the assurance i'll flash with AEX

IMEI trouble with redmi 5 plus

Hi guys, my uncle has given me his redmi 5 plus (Vince) for tinkering around or to fix, to say.
It was dead after minor ingress of water droplets. And person who my uncle gave phone to, recovered the mobile but it's IMEI numbers are lost.
So it's not getting any network.
So far I tried to flash lot many ROMs on it, developer global, global stable, China stable but condition is same.
Strange thing I observed is, in fastboot mode miflashtool gives error for all the ROMs...
Modem error.
And I can flash successfully only in edl model with testpoint method.
Btw mobile is stock, i.e bootloader is locked and it's not rooted. Has stock recovery as well.
And I can't unlock bootloader without Sims functioning based on requirements of xioami.

I could re instate imei numbers finally with one desktop app and opening diag port with ussd code but still mobile isn't getting any network (with back cover opened. I haven't installed it back yet since it's too hard to remove it if required. Don't know whether it has something to do with network reception.)
Don't know what's the reason as I am not aware of telecom technicalities like baseband etc.
So any inputs are welcome and appreciated.

Question I can't get the LTE and IMEI to work again on custom ROM after a Format All + Download and a restoration of IMEI 2 and LTE on engineer firmware

Update :
By flashing only the IMEI 2 I can make the LTE work on the engineer firmware but when I flash a custom ROM PE, EvoX, LineageOS (after a flash of the latest global firmware):
If I manually flash the modem firmware MOLY.LR13.R2.MP.V16.P21 the SIM is not reconized and IMEI 1 and 2 are unknown.
If I leave the modem done for the ROM the SIM is recognized but no LTE, phone call, etc
So... it's still not really solved, I found this solution on treads for the redmi note 9 https://forum.xda-developers.com/t/...nally-first-method-to-fix-1-slot-imei.4258977 and https://forum.xda-developers.com/t/...-in-merlin-redmi-note-9-redmi-10x-4g.4258779/
The PE Rom of the redmi note 9 is visibly compatible with the engineer modem and that's probably why it works with this phone but not the redmi note 11S.
Original Post :
Summary:
I can't get LTE or 3G to work, I tried with several SIM cards that work on other phones.
The problem happened after a formatting and then a complete Flash of the phone with SP Flash Tool to get out of a Hard-Brick.
Issue:
With the Miui ROM, the phone starts directly in recovery and displays nvdata corrupted (doing a "Wipe data" doesn't change anything).
I tried to flash the nvdata,nvcfg,nvram,proinfo,persiste,protect1,protect2 of another Redmi note 11s with mtkclient I manage to start but the SIM card is not recognized and the modem is in unknown version.
On the engineer rom by not flashing nvdata, nvram, etc the modem is in the right version but there is no IMEI and I have no access to the internet and can neither make nor receive calls and SMS.
On the engineer firmware with Modem meta I can flash the original IMEI and the calibration parameters of LTE, WCDMA and GSM retrieved by myself from a redmi note 11s on which the network works with the engineer firmware as with MIUI and after all that I can receive calls but not make any, I can have EDGE but not more and the settings continue to mark "no service" and "radio off", the IMEI and correctly displayed in the settings and when I accept a call the HD logo is displayed, the VOWIFI works and allows to make, receive calls and SMS, note that the serial number displayed in the settings does not seem to be the right one, Everything else works.
On a custom ROM it is identical to the engineer rom.
Context:
My phone ended up in a Hard-Brick following a problem in the unofficiall pixel experience custom recovery (impossible to access fastboot, recovery and system after an "adb reboot fastboot" but Brom mode is accessible).
I used mtkclient to disable the Brom mode protections, I then flashed the firmware V13.0.3.0.SKEEUXM with SP Flash Tool but by ignorance of the software I used the "format All + Download" mode (which has the effect of formatting all the partitions including nvdata, nvcfg, nvram, proinfo, persist, protect1, protect2).
Then I was able to boot but the phone enters directly in a bootloop with nvdata corrupted which is displayed in the recovery, I tried a data wipe but it does not change anything, I used mtkclient to reunlock the bootloader and make the tests that I described in the problem part.
The phone is under warranty but I had unlocked the bootloader, the problem being due to this unlocking, the phone will certainly be considered out of warranty and if they follow their policy in french they will not repair it and the shipping will be at my expense.

After unlocking the bootloader with mtkclient:
I flashed V13.0.7.0.SKEMIXM, flash the unofficial custom rom of Pixel experience 13 with its boot.img, reflash the nvram, nvdata, nvcfg, proinfo, protect1, protect2 from my phone when there was "corrupted nv data" and wipe data with custom recovery.
Pixel Experience works really well, The SIM card is recognized, it shows my operator, baseband version but there is no 4G, SMS and IMEI, IMEI SV is unknown.

There is no way to do it without hardware tool ?
and I don't really understand what you are talking about, can you give me more detail ?

@tutibreaker I updated the original post you could read, even after flashing the IMEI with modem meta there is still no 4G volte and SMS whether on the engineer firmware or the firmware V13.0.7.0. SKEMIXM with pixel experience, SIM and operator detection, baseband version, IMEI, phone number works as it should.
I don't know enough about meta modem to know which option/procedure would make 4G, volte and SMS work again.
nvram, nvdata, nvcfg... from my friends redmi note 11s still doesn't detect the sim card and meta modem can't connect with.
I really need some help please.

I updated the original post again (and again), If someone could help me it would be really nice.
To summarize now I managed to restore the LTE on engineer firmware but not on custom ROM (PE, EvoX, LineageOS)

I have the same problem you can flash gsi but use gsi is sucks

Did you manage to fix it?
