IMEI problem on october patch oreo rom (stock moto) - Moto G5 Plus Questions & Answers

Hey guys, I tried flashing the stock moto oreo rom (october patch) through 1. flashing via fastboot and 2. twrp flashable rom.
Both methods worked but I lost my IMEI, regardless of which method I flashed the rom with.
I had made two EFS & Persist backups (one from resurrection remix rom and one from a twrp nougat june patch rom) and tried to restore them after flashing the moto oreo rom, but no success.
Can anyone help me with this? I really want to use the stock oreo rom!

Please help guys!

Do a stock ROM flash using fastboot method, without "erase modest1" and "erase modest2" codes. It has solved my IMEI problem and it may solve yours also....

You probably have a corrupted persist partition. If you flash the soak test 1 firmware (link is in the TWRP flashable Oreo thread) you may get back your signal.

Could you provide a direct link to the ROM you're referring to? I tried searching for it in your thread but couldn't understand which one to download.

yes that's to be flashed with TWRP. Just dirty flash it over the top of your current rom.
All it is is a few partitions from stock oreo - modem, dsp, fsg. These are used in some way for connectivity, so hopefully they fix things up.

Hey just one more thing to add. After flashing the ROM you provided, the audio quality is really bad on music streaming apps except for YouTube. How do I fix this?

Hi, Look, I have a problem with my Moto G5 plus cell phone. I do not have a mobile signal, according to what I have seen and seen on my cell phone, it is because it does not detect any EFS / IMEI partition, I think it would be useful for me to help you with your backup. EFS for me to resture it to see if it works, do not worry about the IMEI I have the original mine please help me with that I would thank you ..... or anyone who can help me ....

Have you ever flashed someone else's persist file?
If yes you're most probably screwed. All this things like persist (incl. IMEI) and efs are unique to every device. You don't write which android version you're on, maybe it could help you what @NZedPred posted above, flashing soak test Oreo 1 via TWRP.

Thanks for your reply ... I have not tried to update another EFS folder from another device ... I currently have the version of Android 8.0 ROM Google experience, but it's the same ... the IMEI comes out but no signal ...
and the file to flash of TWRP does not work ... I tried to make a backup of the EFS folder with an application and it says that "SORRY, WE CAN NOT DETECT ANY EFS/IMEI PARTITION ON YOU DEVICE"
THANKS.

Would not recommend it, since those firmwares appear to be for US, Amazon or G4 Play devices (amz is for Amazon), so you may end up damaging/bricking your device more than it already is.
Besides, the links I've given you in the other post should enable you to pull the modem files from those firmwares and flash them (though I'd recommend doing a full flash).

Did you try flashing the retail stock ROM from here https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 ? This NPJS25.93-14-18 firmware file is the latest stock ROM for retail EU/UK, Brazil and Indian devices (I'm not sure what other ROMs you've been flashing, I'm hoping flashing the incorrect ROM still means it's fixable...)

After flashing the modem, fsg and hw images in step 7, did you re-flash the latest stock ROM? From what I understand, you need to flash the stock ROM over the pushed images to try to re-link your modem/IMEI.
This seems to be one of the issues of downgrading, and perhaps why Motorola doesn't support you if you do downgrade...

What do you mean by 'how bro???' I don't understand what you're asking for in that question.
Hrm, you could have a look at some of the other topics with trying to get the baseband back - maybe you could try to find a India hw, modem and fsg image to try to flash. Here's a topic that's been trying to fix the issue for a while with limited success: https://forum.xda-developers.com/moto-g4-plus/help/moto-g4-pluss-model-changed-to-g4-lost-t3496912
You can also try these images I've pulled from my XT1642 (UK, EMEA baseband), see if they can let you get your India baseband back after a stock ROM flash: https://drive.google.com/open?id=1vQHJB37RV4Iv83jeO5mymw-UNe9KtRNm No guarantees though - seems that the downgrade to Marshmallow corrupted firmware somewhere?
Other than that, I'm not sure of other methods besides getting your motherboard replaced.
Hurray........ Its worked

Baseband Collection/ Switching Guide

I really think there should be a thread on XDA with tested methods to switch baseband as a lot of people face trouble with GPS etc on custom ROMs. Ideally we should be having a collection of TWRP flashable zips instead of having to install stock firmware via tools like Miflash and then doing everything from the beginning.
This zip from Davideavinavil is TWRP flashable and it works perfectly for me. It doesn't improve things drastically from stock Marshmallow Indian ZUI baseband but would be great for if your GPS is not working or something.
To get the baseband from latest Indian ZUI Nougat Beta follow these instructions from zukfans by Magz Heaven. Tested on my own phone which previously had the above Davideavinavil zip flashed and is now on M8996FAAAANAZM-1.76387.1.92759.1. I wiped everything TWRP then flashed this in fastboot and then went back into recovery and flashed ROM + GApps. If you want to run this in Linux open the bat file as text and use the same fastboot commands with those files in your pwd.
1. Will bootloader be locked again after flashing baseband?
2. Do I have to flash ROM after flashing baseband?
3. Does bluetooth connectivity depend on baseband?
Thx

1. Yes its possible that your bootloader gets locked after flashing. If you do it wrong and doesnt check it after first reboot you can brick your device.
2. No you dont.
3. Someone said when you only flash the NON-HELOS.bin file you can get problems with bluetooth. If its right I dont know.

Thanks for your response. Only reason i asked about bluetooth is because only ONE custom rom works for me bluetooth wise. I'm unable to connect to my cars headunit with any rom except resurrection rom. Would flashing a modem help this? my modem is 9-00026-M8996FAAAANAZM-1.63821.1

Flashing custom roms shouldnt change the baseband. Does connecting work on rr with this baseband? Do you have problems with other bluetooth devices except your car?

Sorry I probably didn't explain that the best. Flashing ROMs doesn't change my baseband but I'm wondering if changing my baseband will fix my Bluetooth problems. Yes RR works with my current baseband and my Bluetooth works with every device I've tried, on flashing to a different ROM none have worked sadly. I've tried to ask around if other people have issues but they all say their BT is working as it should haha

Lenovo Z2 Plus/ZUK Z2 Plus Baseband Update Guide(Keeping Bootloader Unlocked)

Q. Whats Baseband?
Baseband in laymans terms refers to the radio drivers or blobs of the device.
Many users have complained of their bootloader getting relocked after updating their baseband through a zip file through TWRP or even through fastboot
This guide is for updating the baseband through fastboot WITHOUT RELOCKING THE BOOTLOADER
Using this Method Wont Touch Your Bootloader Keeping it AS IT IS (In the same state as without flashing this baseband)
Many a times after updating baseband or restoring firmware backup through TWRP we cant hear sound or the reciever cant hear us during calls OR sometimes in your custom ROM or sometimes even in latest ZUI you cant get VOLTE working despite all correct APN settings
If you face this problem then updating your Baseband will Solve the Problem Most Of the Times
DO NOT USE THIS ON MARSHMALLOW STOCK ROM OR MARSHMALLOW BASED CUSTOM ROMS IT WILL CAUSE PROBLEMS
USE THIS ON NOUGAT STOCK ROM OR NOUGAT/OREO BASED CUSTOM ROMS
CAN BE USED WITH LOCKED BOOTLOADER ON STOCK ROMS
If TWRP is installed then take a backup of your efs partitiom
Using This Tool Will update the Baseband to M8996FAAAANAZM-1.76387.1.92759.1 (Latest Nougat Baseband)
1.First download the tool from this link https://drive.google.com/file/d/0B2CgYqnPbCh_Q2N0Vmd1d00ySFk/view
2.Download and unpack archive
3.Load the phone into fastboot mode.
4.Connect to PC.
5.In the folder with the unpacked package: Run cmd and then flash_radios.bat - follow instruction on screen.
6.Reboot.
For Installation without PC flash this zip file by davide which i have edited so that it doesnt lock the bootloader or change the splash image, using custom recovery.

If u don't need volte than u can dirty flash baseband on any rom naugat or oreo.
But i think volte is gone because baseband is being flashed with some errors. So it can cause problems like signal fluctuations and wifi instability..
For those who getting volte and calling voice bugs...
Flash deodex zui 2.5 indian ..
How i solve my prob
Basically i try oxygen os marshmallow based rom(which degrade my baseband to a mm one) and then i restore my naugat twrp backup....then the voice bug happen.....
Then i flash the latest indian baseband from zuk fans forum....on my custom naugat rom(viper os)
After flashing voice bugs gone...but my volte stops working....
Then i flash deodex stock zui 2.5 indian and enable volte(volte works at this stage) and then flash my custom naugat again ...and everything is fine

If not then follow step 2
2..Flash stock zui2.5 indian....after zui flashing check everything will be working great ..(don't forget to enable volte in stock)

If you already flashed the baseband then you don't need to flash it again, if volte doesn't work for you then you can flash baseband and clear modemst1 and 2 yourself and clean flash rom/gapps/magisk.

If u don't need volte than u can dirty flash baseband on any rom naugat or oreo.
But i think volte is gone because baseband is being flashed with some errors. So it can cause problems like signal fluctuations and wifi instability..

Thanx, I'll do like you said.
I occasionally loose signal bars, then I can't receive and send calls. It's just for few seconds, but it's still annoying coz I have too much calls with partners on my work.
Works like charm!
I'm running AOSP Extended 5.0 Latest Build by @davidevinavil . I just downloaded, unpacked archive, rebooted phone in fastboot mode, connected to my PC (USB 2.0), and ran .bat file as administrator, disconnected phone and restart. Everything is working. Thank you dev for this guide! :good: PS. Not a Jio user so no idea if VoLTE works. WiFi, 4G, Calls work flawless.

UPDATE. I'm using Vodafone (Mumbai Suburbs) and after updating baseband, I'm getting faster webpage loading speeds than before.
This can be flashed on locked bootloader of nougat stock roms?
For Changing Baseband Without PC Flash this zip by davide which I have edited so that it wont relock the bootloader or change the splash image. Baseband version 2.0
https://drive.google.com/file/d/1mHdf2kc0ARpRO6kxAKiI3dotAVY0TJdM/view?usp=drivesdk
calling issues: receiver cant able to hear me properly
First i flashed stock (nougat) ZUI_2.5.104_ST (Indian) volte was working fine calling was perfect on both sims.
Then i flashed aex 4.6 i checked the baseband it was version 1.7 (previously it was 1.6).
Volte is not showing then i have to manually add the apn then volte was there.
But sim1 voice clarity is not perfect receiver cant able to hear me....sim2 working loud & clear
Please suggest to me some method to resolve this

VoLTE Fix For Problems On Custom & Stock Roms [Z2 Plus]

Volte or Voice Over LTE is a feature of LTE(4G) networks which allows the voice and sms to be carried over the mobile network just as data packets unlike older networks which requires a dedicated voice channel.
It needs to be supported by both the carrier and the device to work.
Jio is an Indian Mobile Carrier with solely uses Volte for calling and messaging
In case of our device (Z2Plus) the efs partition contains all details of the modem including the right configuration for using volte and also mac addresses of bluetooth and wifi. Only stock rom has exclusive rights to modify some parts of it.
Custom roms dont tamper with it as it also contains the valuable imei and mac addresses info which needs to be preserved.
If the efs partition is somehow corruped then the phone would be unable to connect to any kind of network
As efs partition contains the volte details and cant be edited by custom roms so it has be carried over from stock rom after volte details are lodged into it. The efs partition if doesnt contain the volte details from stock rom will not give any volte details to the custom rom making volte unable to work on custom roms
So for making volte work you have to first use volte on stock and then move to custom so that the details are carried over
If you have your TWRP efs backup from your phone when volte was working then restoring it might help in regaining the volte functionality on custom roms.
For restoring stock rom of 7.0 nougat follow this guide(recommended) https://forum.xda-developers.com/le...lenovo-zuk-z2-plus-2132-indian-t3678826/page5
If volte doesnt comeback even after installation of qpst stock rom then you need a baseband update on your stock rom, Boot to fastboot mode & then follow this guide. Use the pc tool to flash baseband.

Some users claim that flashing a stockrom throught twrp also works but I have not tested it. If you wanna try this simpler method use this guide https://forum.xda-developers.com/le...xed-z2-plus-nougat-2-5-334-st-t3594483/page55
Also remember if you mess up with your efs partition it would not be repaired by just flashing stock rom!
Is you have somehow messed up with your efs partition(eg. Restoring efs from another z2 plus) then here is the guide to repair it https://forum.xda-developers.com/le...de-restore-lost-imeis-repair-network-t3635734 always remember to take backup of efs partition in recovery

U r asking the network ??? Ok for this flash the zui2.5 firmware through twrp , it would lock your phone's bootloader ,then unlock your phone bootloader with two commands the 1.the unlock bootloader one and 2.the oem unlock one and then Ur phone will boot to twrp ( Ur data and everything will be safe n Ur ROM will be as it was earlier).Now boot to Ur ROM and then again to down the phone unlocking commands here.
1.fastboot -i 0x2b4c flash unlock unlock_bootloader.img (This the first command)
2.fastboot -i 0x2b4c oem unlock-go (second one)
Pls do find out the Indian firmware on XDA it is easier to find,(2.5 firmware,which is twrp flashable)
Also the reset modem commands.
Thnx.

Qfil is different method and the one that I have told u is different method. Remember her that stock zui2.5 firmware only contain the modem partitions , which means it is not the ROM. It's size is around only 25MB or something like this.

I have gone through those tutorials, but I have a bit different problem.
Purchased this phone last year, unlocked BL, & made backup via twrp.
Since then never updated my phone & used various other roms.
Now I want to flash latest stock firmware but facing problem like version mismatch as my previous backup was of stoneage & twrp cannot flash stock firmware.
Asus flash tool is also not helping.

Do not restore your old backup, it won't work. Just forget it. Also, no need to use AFT.
Try this method instead: https://forum.xda-developers.com/as...ow-to/guide-revert-to-stock-rom-lock-t3798420
I use that method for 3 times already and always ended up with success. Just make sure you follow the instructions very carefully. Good luck!
