i can't get 4g speed in my kenzo? - Xiaomi Redmi Note 3 Questions & Answers

I'm using kenzo from two years.
Recently I flashed miui9 official beta ROM.after that next day I can't get even 2g speed (around 80-90kbps). I tried lot of roms,patches, even flashed the modem via adb method and flashed latest firmwares, and I also downgraded to the older miui versions ? but nothing worked. I used my sim card in my friend's mobile (yeah kenzo) and he got perfect speed.
So ,if there any possible solutions please let me know and kindly help me.

Unable to Register On network

Hi this is starting to really bug me now Im unable to register on a network I get signal bars but only get emergency calls only tried dfferent sim cards and reverted back to latest official stock to no avail any suggestions please
As per multiple identical posts .
First is your IMEI correct
Are your mobile network settings correct
sim card correct and tested
correct modem and csc.
jje
Check your IMEI number. Sometimes, when we flash custom ROM, the phone looses its IMEI number. If it's true, you must use an EFS backup to restore it.
Second solution : your mobile phone was blacklisted (if it was considered as stollen).
Network
Hi thanks for the reply I have been searching I've checked my imei in status and it matches details under battery compartment i'm still paying for the phone (pay weekly) so no reason it would be blacklisted ok just tried another different sim card on Vodafone official s3 stock rom and it registered hmmm im on talktalk which uses voda I know this sim works but i'll get them to send me a new one thanks for your time guys

Unlocked i527, IMEI Unknown? How Do I Recover?

I recently rooted my i527 then unlocked it for use on T-Mobile, And it was working just fine, Getting Signal and EDGE, So earlier this morning I took out my sim card and rebooted the phone a few times, Changing the APN from epc.tmobile.com to fast.tmobile.com thinking that was going to get me from going from EDGE to 4G or LTE... Yeah Right! Little did I know, It requires a lot more than just changing the APN.. But thats beside the point.
Anyway, While I was taking my sim out and rebooting, After once or twice of doing this, The phone would not come up with T-Mobile signal AT ALL. After a while of just blankness it would pick up What Im guessing is WCDMA signal or something, But not T-Mobile Active signal like it was doing just fine before. So after 20 or so reboots (thinking that was the problem), And looking around, I noticed that the phone is not issuing a IMEI number. Not in settings, and not *#06# either. The IMEI number has been lost. When I go to settings to view it in About Device it just says "Unknown". I'm assuming this is my problem, Once I get the phones IMEI number back, It will pick up T-Mobile signal again.
At the beginning of this, I was simply trying to get high speed data on the device.. Now I can't even make and receive phone calls. :crying: Any help on how to recover the IMEI would be great, and highly appreciated.
Thanks

If you still have the unlock code try reseting the phone using kies... then see if your imei comes back..
Used ODIN to install correct ROM. This might help.
Get your officla ROM from http://www.sammobile.com/

SamMobile still doesn't have AT&T sgh-i527 firmware. Use kies to recover your phone or odin with the posted firmware on this forum. Kies would be the safest.

[Q] Need Help With Mega Please

Ok,
Rooted and unlocked the mega now no service. Searched for 16 hours on how to fix the network. I have a friend who forwarded me both the nvm and also a clean efs file. No matter what i do i can not get service. It shows service and 4g lte then when you dial the phone number and press dial it drops to 4g then the signal bars, and then the no service signal. I have checked the imei and its clean. Also the imei is NOT null or 0 out. If anyone can help it would be very much appreciated.
Also i have already tried to reflash the firmware and that did not work either.
I read in another forum alot of people had success with a good qcn file from rekamyenoM but i could never find the file. I did download some other qcn files but they did not work. It was working fine on att before i tried to unlock it.
Again any help would be appreciated.

No Service After Unbricking D620

A few days ago LG G2 Mini LTE D620FR was suddendly bricked. After I searched on the internet, I found a solution how to unbrick it. Although I flashed the certain kdz file according to its IMEI number, I have no service on it.
My IMEI indicates that my product comes from France but I'm using it in another country (Greece) so also flashed the greek rom but nothing changed.
Sim cards from various carriers are detected (Cosmote and Vodafone) but it shows zero signal.
Also before the brick the phone worked fine (cellular network) and it wasn't rooted.
I have been searching for days in order to find a solution, so I really appreciate if any of you have a clue about how to overcome this problem.
Thanx in advance
The problem might be on the EFS partition.
I think that's how it's called.
It contains information required to connect to the network.
I'm not sure how to fix it. Look it up online.

[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!

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!

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
