Need help, messed my g930f modem, odin won't reflash, need files!

Hello,

I'm running Nougat on my s7 g930f it's using the tgp rom. In preparation for an oreo upgrade I atempted to flash an odin-zip file I found on LightRom's page, thinking it would give me a modem update. This was an extremely bad idea. Now my system does still boot, but I have no signal at all, my phone number, base band, IMEI, mobile network, etc all show as unknown under settings, about phone and the various status checks. Now when I atempt to go in to odin again to flash another modem update now I'm told that the atempt has failed. I'd appreciate some help. What file do I need to get the bl and the cp file? I'm running twrp 3.2.3, and i'd like my signal back.

I just ran phoneinfo and found out my original and active csc codes are both the same as TMB, my country code is TMB-USA. I hope this helps. The filename I atempted to flash, which reported as success and I wish I had found this forum first, is an all-in-one bootloader/modem called:

BL_G930FXXS4ESAE_CL14843133_QB21796491_REV00_user_low_ship.tar.md5

I believe from reading posting 1 in this forum that this xxs has branded my phone something, which was not my intention, it's an international unlocked s7 g930f, and I need to fix this. I'm thinking to now flash via twrp, which I've got version 3.2.3 installed. I'd appreciate any suggestions as to how to unblock this failure now of odin to flash files, so I can flash via odin the file I just got from this forum which is:

CP_G930FXXU2DRB6_CL648265_QB8952207_SIGNED.tar (1).md5

or where to get the right zip file to flash in twrp to get this fixed.

Some urgency!

Thanks.

Dave.

Do you have a Nandroid including the EFS?

You said that your device no longer Boots - So I'm curious as to how you know that the baseband is "unknown"?

My first suggestion would be to Restore your last Nandroid including the Modem & EFS.

If you want to update the Modem (what I would do) Is Download the Stock Samsung Firmware for your device to your computer & then Extract the Modem & Flash it with either TWRP as a zip - Or Flash the tar file with Odin (my first choice).

You should always have the latest Stock Samsung Firmware on your computer for the "just in case" moments...

Hopefully these initial questions & suggestions will be of help ?

follow up to boot loader and modem, s7

[MENTION=4351374]shaggyskunk[/MENTION] Thanks for your reply. My phone does in fact now boot that's how I know that base band IMEI, and the other referenced information is unknown.

I do not have a nandroid backup. What I do have is an efs taken about a year or so ago with a program called efsbackup I believe it was made by an arab xda-developer. It made two .tar.gz files one called efs and a date.tar.gz the other radio and a date.tar.gz. Unfortunately, I have not been able to get it to restore, that was my first thought.

I can't get odin to flash, that was my first thought as well, it's looking at me and seeing failed something .bin file. That's why I was asking about how to flash these files in twrp as I do have that and it is working. Could you tell me how to acquire or make the needed twrp-flashable bootloader and modem zip files?

Thanks.

Dave.

---------- Post added at 04:16 PM ---------- Previous post was at 03:30 PM ----------

Adding to my previous messages I've got my efs backup tar.gz files they are .img files when extracted. I've got a file efs.img and a file radio.img can I flash these with twrp?

making progress but still have sick phone

Hello,

I've got a very sick s7 g930f, it's an international unlocked version. I'm in the US and using tmobile as the cell carrier. In preparation for an oreo upgrade I'm running a rooted nougat rom tgp with twrp 3.2.3, I decided to update my modem and bootloader. Well, very very bad idea, lost signal, can't dial, no IMEI number, no mobile network, no phone number, all of that is showing as unknown. I had a backup of my efs partition, I took it about a year ago and it made two files one efs date.tar.gz and radio date.tar.gz, extracting both of those revealed a efs.img and a radio.img file.

I atempted first to reflash a known stock modem and bootloader, these failed, until I restore the efs.img image to the efs partition. I did it like:

dd if=/external_sd/efs.img of=/dev/block/platform/155a0000.ufs/by-name/EFS

that worked, in and of I could now flash the stock nougat modem, this went without a problem. The problem now is the bootloader that was flashed it's bl_xxs which means my phone now thinks it's branded, which is probably why it isn't working. I need to flash a bl_xxu unbranded image and hopefully things will work. where do I get an unbranded bl_xxu nougat img file and how do I flash it when I do to the boot partition? And how do I flash that radio.img file and to which partition? Help appreciated.

Thanks.

Dave.

930F Modem on 930W8

Hi everyone, I just want to know if it's possible to flash a 930F modem on a 930W8 device. They have exactly the same hardware and I tried with odin but it didn't work... Do you have a solution ?
[Samsung Galaxy S7 Guides, News, & Discussion] shaggyskunk:
Not exactly sure why you would want to - Possible explanation might be if you are residing in the EU - But still I wouldn't expect to see any real benefit & more likely to experience issues with VoLTE - WiFi Calling etc - I wouldn't do it ?

Sent from my SM-G965W ??
[Samsung Galaxy S7 Guides, News, & Discussion] P0st00:
The explanation is that my phone is a 930W8 and i want it to be 930F. I succed to change the CSC on a custom rom so i'm able to make some calls and have network but it's really low network and sometimes it cuts... I think it's an issue with the modem that is still canadian (930W8). Do you have any idea how I could change it ?
[Samsung Galaxy S7 Guides, News, & Discussion] shaggyskunk:
First of all - Where are you using the phone - ie: What country or region?

Regardless I can take my Canadian SM-G965W and use it perfectly well pretty much anywhere that the SM-G965F is available - So your explanation still doesn't make sense - At least from the information you have provided to date.
[Samsung Galaxy S7 Guides, News, & Discussion] P0st00:
I'm from France and with the stock ROM of my SM-930W8 I couldn't have network at all. As I explaied to you, I succeeded to Flash a custom ROM and get the right CSC file. BUT, my network is still low, and I think it's due to my CP file (modem). So I would like to change it to a 930F CP file.
[Samsung Galaxy S7 Guides, News, & Discussion] shaggyskunk:
That's strange - I've been through most of Europe - The US & Asia with my Canadian devices & never had any issues with connectivity... I guess (hope) that if you're living in France that you have a French Carrier & you're using the APN for your Carrier?

There's no reason why you need to Flash the F variant Modem in order to get Voice or Data!

If you're determined to potentially mess up your phone - You can try using Patched Odin to flash the F Modem in Download Mode...

I know quite a few people in North America who have purchased various F variants beck of the Unlocked Bootloader & Didn't have issues (other than with VoLTE & WiFi Calling which is expected) Without Flashing the North American Modems.... I suggest that you purchase the F variant if you are planning on staying in France & are hell bent on the F Modem....
[Samsung Galaxy S7 Guides, News, & Discussion] P0st00:
I use the right APN, I succeded to change my CSC file on a stock ROM but still have low network i don't understand. I'll try with patched odin to see.
[Samsung Galaxy S7 Guides, News, & Discussion] shaggyskunk:
Be careful with Patched Odin - It's designed to let you Flash files that are not necessarily Safe! ?
[Samsung Galaxy S7 Guides, News, & Discussion] P0st00:
I tried with patched Odin and it fails... I can't flash 930F files into my 930W8 phone..

Help me if you know please

Hi, I just got an S7 g930f off of ebay Im currently in the united States of America. The international unlocked version does not have firmware for the united states. The firmware that came on the phone was Arab Emirates or Sadi arabia something like that. If I have to I have a stock back up I can go back to. Im under the impression that I can flash any country firmware for my model. Im thinking the United kingdom BTU version is the best option. Am I correct that I can flash an Oreo United kingdom version.? And is that what you guys would recommend? I only bought the phone to root and mod play around with theres no sim card going into it for now anyway. I rooted and flashed twrp after it charged right out of the box im currently on Light Rom pie. I just wanted to make sure im on the best firmware for english and rooting purposes. Thanks also what bootloader and modem?
[Samsung Galaxy S7 Guides, News, & Discussion] redjamesg:
I would recommend to use BTU, if you are planing on using it with developer ROMs then make sure only to flash modem and boot loader, otherwise you could end up erasing TWRP especialy if you flash AP.

[MENTION=4664705]redjamesg[/MENTION] I want to update my modem. I have a SM-G930F with Lineage 14.1 and live in Germany (DBT). The last unbranded modem I could find is from 01/2019 (G930FXXU3ESA3), later releases are all branded if I understand your first post correctly (G930FXXS...)

I plan to upgrade my S7 to Android 8, maybe even Android 9. Can I use the modem from Android 8 for Android 9 ?

Can you attach the files for the latest unbranded BL/CP for SM-G930F DBT ?

Thank you very much.
[Samsung Galaxy S7 Guides, News, & Discussion] rho-bot:
Latest DBT FW can be found here: https://www.sammobile.com/samsung/galaxy-s7/firmware/SM-G930F/DBT/

BL_G930FXXS7ESL9 / CP_G930FXXS7ESLA

There is no branding on Bootloader or Modem FW

Yes, you can use this combo with LOS 16 or 17.

Disclaimer:

If you decide to update to the upper one, you cannot downgrade later, as the Binary Level of the upper BL is "7" . Therefore, keep the factory recovery image (in case it's needed later).

The Binary Level topic is generic & everybody should be aware of this limitation

Hi! [MENTION=4664705]redjamesg[/MENTION]

What happens if you cross-flash Bootloaders and Modems? For Example what If I have the FD ( Duos ) Variant and I flash the G930F Bootloader/Modem? Would that make a difference?

Thanks all! I was just curious about this since my friend has the Duos Variant and he also wants to install roms :)
[Samsung Galaxy S7 Guides, News, & Discussion] ChristopherXDA:
I've flashed regular s7 firmwares and the modem/bootloader mentioned in this thread on my s7 duos. The only issue I had was Samsung Pay broke after flashing these modem files. To fix that, I just reflashed the latest Germany (DBT) firmware, using the Home_csc file. Didn't lose any settings and s pay started working again.
[Samsung Galaxy S7 Guides, News, & Discussion] redjamesg:
As mentioned by [MENTION=5232198]ChristopherXDA[/MENTION] it is piossible to flash these modems and bootloaders on the FD version.

Although I wouldn't do it on a whim, there could be an issue with a particular modem or bootloader, so I would keep a copy of the latest working ready to flash just in case something was wrong.

Keeping this in mind, TWRP suooorts FD version and several custom ROMs suooorts it aswell, so I don't see any oribkemsvin yiur friend venturing into flashing a custom rom on his FD.

Very strange but, after the flash is complete and Odin reports "PASS!", nothing happens to the phone, it still shows "Downloading..... do not turn off target" and can not be reboot except the same way (download mode). Flashing of different bootloaders (i mean older versions of same) or flashing twice at a time does not change everything. Does anyone know what can be done?..

Upd: had to re-flash completely - through Odin, with an official 5-file ROM, nothing else helped. Very strange.

The provider specific details are held in the CSC file, so it shouldn't matter.

How ever there are specific bands being used depending on where you live, since it seems the modem is supporting all of them I wouldn't worry it's only in case of lost signal a flash of you region specific release would be advisable.

Were you guys able to get by it?

Just wanted to confirm if its possible to flash the modem alone by selecting CP only in Odin?

I have G930FD with Baseband(G930FXXU1BPH1 ) and Bootloader(G930FXXU1BPH7)

Not happy with the modem because of signals and cell standby draining too much battery.

Please help.

[Samsung Galaxy S7 Guides, News, & Discussion] redjamesg:
I have a similar issue, when ever I update my bootloader, I need to refresh my ROM, otherwise my phone will only boot into recovery.

But since I try a lot of different ROMs and configurations I don't find it to be that big a deal.
[Samsung Galaxy S7 Guides, News, & Discussion] redjamesg:
Yes you can flash the modem alone, or boot loader as the only one.

How ever sometimes the changes in the boot loader are so drastic that the ROM base and modem is depending on those, which is why you might run into boot issues when updating just one or the other.

Can you get it to biot into TWRP at all?

When using the non EU branded versions you can encounter a boot loader that will trigger security password on boot, usually default_password will work, if you do experience a situation where it isn't working, then revert to the original stock firmware your phone came with, and start your rooting/custom ROM/boot loader/modem upgrade from scratch.
