Moto G4 Plus's Model changed to G4,lost one imei and finger print.

[Soureen]

I have switched to a new device and no longer use this phone but i see many others facing this issue as well so I am keeping this thread open, please do not message me regarding the solution to this issue cause all i did to get out of this mess was getting a new phone.




Hello !

Due to some error while flashing stock rom on Moto G4 Plus XT-1643 my Moto G4 Plus has changed into Moto G4 but the model no shown in the "About Phone" section is correct.
I have lost one Imei no. fingerprint option is no where sim or mobile network doesn't work other than that the phone is fully functional(WiFi,Camers,Audio etc)
There are multiple threads on the same issue but no solution is available I would be highly grateful if anyone could find out any solution to this issue.

P.S : I have tried flashing multiple ROMs available on the forum specific to XT-1643 i.e Indian Version

Also I flashed the OTA file for the Android 7.0 Soak Test due to which I cannot relock the bootloader.

I am currently on Stock Marshmallow 6.0.1 139-63 Rooted&TWRP installed

The phone is basically an iPod without fingerprint sensor

I had the same issue. I relocked the bootloader and sent to service center. They flashed the original firmware. Stock roms roaming here are not exactly stock roms.

this happened to my phone (1640 - brazilian moto g 4 plus), and I tried every single rom out there for moto g 4 plus, and it is only identified as Moto G 4, without fingerprint or any modem activity.

i still cannot recover previous bootloader, because it don't downgrade bootloader version. nothing worked for me so far.

i'll be watching this thread to see if anyone comes with any alternative.

Umm, so according to you too it's a software issue and not a hardware one right ?

The first thing that I do when I boot in TWRP, I do a full backup of all the phone's partitions, and save a copy on my PC, so I can restore the phone in cases like this.

if you flashed android 7.0 and then downgraded to android 6.0.1 then expect some bugs because your bootloader gets updated you have to do clean flash but you cannot actually completely downgrade to android 6.0.1 after you updated to 7.0 soak test bootloader still remains updated and your phone will brick when you click update after you receive 7.0 official OTA i warned you this happened to lot of moto x users do some research before you do anything if the phone is your primary device

I think so. May be if we flash a wrong modem, the right one never flashes correctly. I don't know how do they managed to flash it correctly.

For me its a software issue... looks like it messed with the bootloader, and since you cannot rollback to an older bootloader, the phone works like an iPod Touch. haha

I hope that when Motorola releases the final 7.0 version for 1640, I'll be able to flash again the right bootloader and that will fix the phone.

I did a full flash of an older 6.0.1 ROM, and it still doesn't work. Since the only thing that I couldn't flash is the bootloader, and the phone identify itself as Moto G 4 (and not Moto G 4 Plus) my guess is that the problem is with the bootloader.

I guess i'll have to wait for the official 7.0 for my specific phone (1640) to fully replace this broken bootloader.

 

[SoNic67]

Yeah, that's why I didn't upgrade to the N yet, I was sure that the bootloader will be different.
I also have saved the partitions with Partitions Backup & Restore app, after rooting.

Did you try the ElementalX kernel?

I was also having same issue,got my bootloader locked and went to service center and they replaced the motherboard for free????

 

[SoNic67]

Lucky you

Has anyone found a solution to get the plus (fingerprint) back to the phone?

 

[Soureen]

Nope funny thing no one knows anything ??

I am waiting for the Android 7.0 official update so that I can relock my bootloader and send it for service.

 

[benedictusg]

That's a bummer but there might be some solution. The phone version number shouldn't be that hard to find if you'd knew witch file that flashes it.

How do you do these backups for they don't look at all as twrp backups so I guess twrp is second best to something. But what?

What is the different with 7.0 coming up? Can't you just relock a backup?

I have the same issue, I have seen people with XT1643 having athene_f in build fingerprint but I have only athene. Which one is correct, could this be the issue?

Managed to solve the issue at least to get the signal. This is what I have done
- Restore my first TWRP backup.
- Booted directly into bootloader and NOT system, flashed modem for the build.
- Rebooted and I am getting the signal!!!

Radio is working after TWRP backup + modem flash. Still fingerprint is not working and it is pointing out as athene not as athene_f

(bootloader) ro.build.fingerprint[0]: motorola/athene/athene:6.0.1/MPJ24
(bootloader) ro.build.fingerprint[1]: .139-63/64:user/release-keys

I have spent 1 whole week to get the signal working, at least be glad that you can now use your phone and press thanks if I helped. Regarding athene in build fingerprint you can easily change that in build.prop but it won't help. I think fingerprint service is disabled because ROM thinks that our phone is G4 and not G4 plus. I have tried few things to enable it but not getting it to work, will update if any of my experiment is successful.

I found this trick early and I am using it now. I thought you cracked the last part (fingerprint sensor) which my post was about. I think that the issue is with gpt bin as I tried different bootloader versions along with all possible combinations. Gud to see someone else is working on the same. Will update if found any.

find the correct firmware for the device and flash it else it would lead to such errors
