flashing with older modem.bin crashes app

[Galaxy S6 SM-G920F]

I do not know how to generate a CP_ file like you ask above or where to find it. SamMobile only has tar.md5 files from which I can extract the bin file. I assume a CP_ only contains the modem.bin?

So I used Odin3 v3.10 to flash the modem.bin file from G920FXXU3DPER_G920FOJV3DPE3_G920FXXU3DPF2_HOME.tar.md5 which is dated 2016/06/10. Anyways the flashing was successful but when I execute your app it crashes. I have sent a feedback report via the phone which I think includes logs. I also tried flashing the whole ROM but that doesn't work, it fails at boot.bin so I suspect the bootloader version is different.

It could also be that there is some difference with the S7 modem and the S6 modem comms and that may be why your app crashes. Anyways I hope you can investigate and revert back. Let me know if there is any info I can supply! It would be great if your app can also be used to remove the region lock from S6 devices!
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
The S7 firmware on SamMobile is packaged differently (a single ZIP file containing several tar.md5 files, with one tar containing the modem only.) The S6 seems to be using the old packaging structure. Anyway, flashing the old modem.bin is the goal and should work.

As for the crash, we can see the source of the problem (reading the RIL product code). But we need you to run the following and send back the results to see why the app is unable to read the RIL product code.

getprop | grep -i ril
getprop | grep -i product
[Samsung Galaxy S7 Themes, Apps, and Mods] vmostransistor:
I did a getprop and I assume the product info you want is the ro.product because I don't see any other product info. seems there are some missing ril info on the old modem.

But I also see now that the G920FXXS4DPG3 modem date is before 1 August so shouldn't that have worked then? Maybe that's why the app said that it possibly supports region unlocking but when I ran it it said failed to get lock info.

[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
The app was looking for "ril.product_code" setting value and crashed when it couldn't find it. This entry is not critical and we could easily bypass it. However, there are many other missing RIL properties from your device after flashing the old modem. This suggests that the RILD probably failed to initialize, either due to some incompatibility introduced by Samsung between the old and new firmwares you are mixing or due to incorrect modem bin flashing.

The date 1 August is used as a quick inaccurate check for now; i.e. just a best guess based on a few tested ROMs for S7. The exact modem version where Samsung killed the unlock backdoor used by this app is still not identified exactly. Also, whether the same change was rollout to modem firmwares releases of other devices in the Galaxy family around the same time is just a wild guess and is yet to be verified.

Perhaps you could flash the full old firmware to avoid any incompatibility the RILD might be having? (You mentioned that flashing the old ROM fails at boot.bin. I guess that is probably due to downgrade protection. I'm not very familiar with this area but I believe you might find better directions towards downgrading S6 images in this forum.)
[Samsung Galaxy S7 Themes, Apps, and Mods] technomedico:
Unfortunately it did not work for my Galaxy S7 Edge. I did everything as you mentioned (flashed the older CP via Odin, rooted the phone). Then I purchased "the unlock" via app, then app proceeded with the process and finally showed that the device is region unlocked. But the phone is still unable to search/connect to a network in India.:( What may be the problem?
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
Some networks in India are CDMA and others are GSM. Are you sure there are no incompatibility problems?

If you tried other SIM card and it still didn't work then you can email us and we'd refund you the cost of the unlock.
[Samsung Galaxy S7 Themes, Apps, and Mods] technomedico:
I tried 4 GSM SIMs but none worked. Sir please keep working on it to make it compatible with more devices.
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
The app has successfully been used to unlock SM-G935F Galaxy S7 Edge. Perhaps yours was network carrier locked?

Anyway, please email us the purchase date and transaction number and I'd see that you get refunded the amount you paid.
[Samsung Galaxy S7 Themes, Apps, and Mods] amitdogra:
I'm trying to unlock my Samsung S4 Mini (serranovelte) but I'm getting parsing error. Has anyone attempted this app on S4 Mini. My phone was bought in Denmark and I didn't notice the 5 minute activation thing at that moment. Now I'm trying to make it work in India.
[Samsung Galaxy S7 Themes, Apps, and Mods] cyke0213:
this app not work on me.

already followed all the instruction

Downgrade to the compatible firmware.

and root my phone then run the apps but nothings happen after the pop up Successfully Network unlock

i tried the Changing CSC on ES EXplorer and that method works on me..
[Samsung Galaxy S7 Themes, Apps, and Mods] technomedico:
My phone is not network or carrier locked. However I contacted Samsung UK and they replied saying that the network frequencies are different in India and UK. I am not sure but this may be the cause of the problem.
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
I'm pretty sure it's an incompatibility of some sort as we've seen the same exact model (SM-G935F) getting successfully unlocked through this app before. Anyway, we've sent you a refund. I hope you manage to get your phone working.
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
It didn't work on Galaxy S4 so it'll likely not work on S4 mini. However, you can easily test it. The app will perform a test and notify you of the possibility of unlocking prior to performing the actual unlock.
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
What is the model of your device?

When did you attempt to unlock?
[Samsung Galaxy S7 Themes, Apps, and Mods] technomedico:
I think you are right, it is most likely an incompatibility of network frequencies. But thanks really for your time and effort.

As for my phone now I am thinking of 2 options

1. Selling it at ebay or Olx

2. Buy a new phone online and then exchange my unit with the new one (you know what!)

SM-G930FD From Philippines GLOBE network LOCK

i try to attempt to unlock October 19.

see on page 1 i already comment their.

downgraded my S7 to APEQ firmware and Root my device. Brick my warranty to make UNLOCK by your apps.

but it's failed.
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
I couldn't find an unlock operation from your country on that date. Are you sure you went through the unlock steps till the end?

Is it possible that you might have only passed the unlock test successfully but haven't performed the unlock operation itself?
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
Good luck.

Do i need to try again the unlock process using your apps?

is your apps supported my country for unlock now?

Thanks for your reply.
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
The app is not restricted and should work in all countries.

The app is not compatible with Galaxy S4.
[Samsung Galaxy S7 Themes, Apps, and Mods] dtriguero:
Thanks for the the quick reply I know it's not compatible at this time but do u plan on possibly supporting it in the future if not no biggy the original by chainfire still worked for me just had to flash back to an old stock rom

sent from my SGH-M919 BadAss TinkerToy
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
There's currently no intention to make it work on the S4 and other relatively old devices. It's great that you can get the original to work on these devices.
[Samsung Galaxy S7 Themes, Apps, and Mods] lloman.br:
Thanks, I followed your instructions and the app worked perfectly.

Galaxy S7 edge.

I´d like to know - is this unlock forever? Can I install another ROM?

Thanks,
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
Congratulations!

This unlock will survive updates, upgrades, flashing new custom/official ROMs, and even factory resets.

This unlock method involves modifying data in the NV Data file that is specific to your phone (contains unique things like IMEI, serial number, locks). Such unique information are not supposed to be touched upon upgrades/updates of any sort.

We can't however guarantee it will remain like that forever because we don't know what Samsung would implement in its future ROMs.

So for now I'd say you can safely install the desired ROM and enjoy using your phone :)
[Samsung Galaxy S7 Themes, Apps, and Mods] vladmir:
Great news! Thanks for your work!

Any news for unrooted devices?!

Enviado do meu SM-G930F através de Tapatalk
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
You are welcome! :)

Unfortunately the demand for the unrooted devices support is too little to justify the time that will be taken to release this function. So we have this a low priority.
[Samsung Galaxy S7 Themes, Apps, and Mods] DefinitelyUnreal:
This feature requires billing, which is not working with your device.

what does it mean?
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
The app is free but there's a minimal fee requested to support the development whenever you use it to unlock a device.

The message above is shown when the app fails to forward you to Google Play payment due to some error. This may happen for example if there was no Google account associated with your Android device. There can also be other reasons for this failure, but it is difficult for us to guess/troubleshoot since this payment operation is handled entirely by Android and Google.

I suggest you try the unlock operation again and also see if you can start a purchase of any other app on Google Play (you may only need to try initiating the purchase and see if it works before you can cancel the payment on the credit card screen).

Please let us know if you didn't find anything wrong with your device yet the problem persisted.
[Samsung Galaxy S7 Themes, Apps, and Mods] DefinitelyUnreal:
Thanks, It's alright now, so happy that I purchased the IAP. cheers.

not working on kp3 latest firmware

yep sent report
[Samsung Galaxy S7 Themes, Apps, and Mods] Cid_BR:
There's anything else to do than the root on the phone? There's a tutorial for doing this, because i never rooted a phone.
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
We had plans to release a non-root version but unfortunately we postponed the plans since there was no heavy demand.

You should be able to find a rooting tutorial on XDA developers for you specific phone model, together with links to tools used. The steps for rooting are pretty straightforward but you have to be very careful and follow the steps exactly and use a rooting package exactly matching your phone model or you'll risk messing up your phone. Also note that rooting your phone will likely void your phone warranty.
[Samsung Galaxy S7 Themes, Apps, and Mods] Cid_BR:
Yeah. I've searched a lot of tutorial to root my phone, but I still have questions about, but I'm not gonna bother you with it. My real question is: after root the phone, I download the app and just execute it? Simple as that?

By the way, thanks for replying.
[Samsung Galaxy S7 Themes, Apps, and Mods] tmc8713:
I have tried to unlock my Samsung Galaxy S7 Edge but it failed. The message came out was "Operation failed: Failed to get lock level".

Software version: G935FXXU1BPLB

Modem version: G935FXXU1BPJJ

There's a notice beside the modem version saying " This modem firmware version likely has region unlocking disabled. Only expect product code changing to work".

So what should I do to proceed?

Thank you
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
You're welcome. We're excited to talk to people who find this app useful.

Yes, the app will guide you. But note that, depending on your phone firmware version, you may need to downgrade your phone modem Software to an old version that supports the unlock method implemented in this app. You should also know that after the unlocking possibility is verified, you'll need to perform an in-app-purchase of about $3.5 to proceed with the unlocking. You may freely use the app though to change the product code free of charge.

If you'd tell me the exact model number and firmware version on your phone, I could check the compatibility first and tell you what to expect before you'd go through the rooting hassle.
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
Unlocking G935F is supported and other users have unlocked it successfully using this app. The version of your modem was compiled in October 2016 though. Unfortunately Samsung has removed the unlock method we use from modem firmware released on/after August 2016. So it will likely not work directly.

You may try to unlock, but if it doesn't work directly (expected), all you need to do is to temporarily flash an older version of the modem and then the ability to unlock your phone through this app should be regained.

You can find all the old official stock firmware releases for you phone here:

https://www.sammobile.com/firmwares/database/SM-G935F/
[Samsung Galaxy S7 Themes, Apps, and Mods] Cid_BR:
I'll be much appreciated. But I don't have the phone right now with me, it's with my fianceé. I'll get the phone this weekend and send you the Model number and Firmware version. Thanks a lot.
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
You are welcome. Anytime.
[Samsung Galaxy S7 Themes, Apps, and Mods] Cid_BR:
Hey Zigbrick, I have the phone now. The phone model is SM-G930F and the version is: G930FXXU1BPJJ
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
Your phone should be compatible and can be region unlocked using this app.

You can try this firmware:

https://www.sammobile.com/firmwares/download/66759/G930FXXU1APB4_G930FZTO1APB5_ZTO/

It is the earliest one for Brazil and it should likely have the unlock capability enabled.

Alternatively, if your phone is from the UK, and you prefer to keep the UK firmware, then you can try this one:

https://www.sammobile.com/firmwares/download/66525/G930FXXU1APAW_G930FOXA1APBA_BTU/

You don't have to flash the whole firmware. Only the modem part is needed. You still need to download the whole firmware but you should be able to easily extract the modem part. I believe you can find details on that up this thread. Let me know if you need more directions.
[Samsung Galaxy S7 Themes, Apps, and Mods] Cid_BR:
I'll try the Brazil one. Since Sammobile limits the download bandwith, I'm downloading the file right now. After that I'll flash only the modem (which is the CP, right?), root it and then try the app?

Thanks for the help.
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
Yes, flash the extracted CP tar, then root, then run the app. You are welcome.
[Samsung Galaxy S7 Themes, Apps, and Mods] Cid_BR:
Alright. The phone is flashed and rooted. The app is downloaded, so I just put in the SIM Card and press that key button on lower right?

Booom!!! Worked!!! Thanks a lot ZigBrick, sorry if I annoyed you!!
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
Not at all. Glad you find the app useful.
[Samsung Galaxy S7 Themes, Apps, and Mods] un-droid:
How to make the in app purchase?
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
When you try to unlock, the app first tests the unlocking possibility. If the test is successful, then you are asked whether you want to proceed and then the in app purchase dialog appears.
[Samsung Galaxy S7 Themes, Apps, and Mods] bse4792:
any change it could be updated to work on all samsung devices like J200gu?
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
Unfortunately it's not possible to get it to work on all devices. Samsung makes changes frequently and this unlock method works only on the most recent devices. Also, it is very difficult to test it on the various devices to ensure full compatibility and avoid side effects (e.g. bricking devices).

However, since the J2 is recent enough, you might want to try it at your own risk and let us know if it works. Just make sure to make full backup, especially for your EFS before trying.
[Samsung Galaxy S7 Themes, Apps, and Mods] bse4792:
i tried already, but it failed.
[Samsung Galaxy S7 Themes, Apps, and Mods] ffonegod:
phone is rooted but when clicked on key..app saying need root
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
This is strange error that wasn't reported previously. Please first double check it's not a broken root issue before we investigate the problem in the app:

Make sure your root is working. (Root check)

Make sure you granted the app root permission when asked by Super SU.

Let us know if the problem persists. To investigate further, we'll need information such as device model, Android version/build.
[Samsung Galaxy S7 Themes, Apps, and Mods] xloku:
Thumbs up for this! But is it applicable to S7 duos version (G930FD)?
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
The G930FD is very similar to the G930F. So yes, it should likely work.
[Samsung Galaxy S7 Themes, Apps, and Mods] saiditec:
hi, does it work for G930FXXU1DQB1

if not do you have any suggestions

thx
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
Unfortunately it doesn't. You need to flash an old modem before August 2016 to get it to work. Please check the thread for more details on where to download the old stock firmware and which specific component you need to flash exactly. Please let me know if you don't find answers to your questions or have different enquiries.

Strange. Do you have busybox installed?
[Samsung Galaxy S7 Themes, Apps, and Mods] saiditec:
Yes, i have BusyBox Installed

Is there any specified cmd to look for ?
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
The check consists of running "su" and then executing "id".. the expected result string should contain the string "root". Please let me know what happens in your case. Perhaps it can't find su or returns a different string?
[Samsung Galaxy S7 Themes, Apps, and Mods] saiditec:
id returns uid=0 gid=0

no root string
[Samsung Galaxy S7 Themes, Apps, and Mods] ferndezmond:
I am getting the same error. I ran id and got uid=0(root) gid=0(root) groups=0(root)
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
It seems like a universal problem.

I have just released v1.0.8. It fixes the problem you were seeing (failure to detect root). It also provides non-root support. Please let me know if you face any problems.
[Samsung Galaxy S7 Themes, Apps, and Mods] ferndezmond:
It says that unlock is possible but the play store crashes when I click the prompt to go to the play store
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
Whoops. Will work on a fix very soon.. Stay tuned.
[Samsung Galaxy S7 Themes, Apps, and Mods] ferndezmond:
Thank you. Really looking forward to using my 935F!
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
V1.0.9 was published. Please check if that fixes your problem.
[Samsung Galaxy S7 Themes, Apps, and Mods] saiditec:
Hi, thankyou for the quick update but this version doesn't detect root at all , prompt me the non root method and get "failed to get lock level" after script starts and puting phone ip

ps : i managed to bypass the root verification in the previous version by tricking the app but stuck in "preparing to backup ........"
[Samsung Galaxy S7 Themes, Apps, and Mods] ferndezmond:
I am not seeing this version in the play store
[Samsung Galaxy S7 Themes, Apps, and Mods] ferndezmond:
Worked like a charm. Thank you so much for this!!!
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
Great news! Please consider adding an app review on Google Play together with your device info so that others can refer to and check compatibility.
[Samsung Galaxy S7 Themes, Apps, and Mods] ferndezmond:
Thanks. I will. Will this also survive flashing a custom ROM?
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
Yes, it should.
[Samsung Galaxy S7 Themes, Apps, and Mods] ferndezmond:
Flashed supermanrom and it doesnt seem to be working. I will restore to the previous state and see what I get

Edit: Restored to the previous state and it is still not working. To add to this I have tried to redo the unlock procedure with no luck. It comes up with a vector of all 0s. I have also tried reflashing everything to stock and starting over and I still get all 0s and no connection. Any insight/advice?
[Samsung Galaxy S7 Themes, Apps, and Mods] ZigBrick:
It is stuck in preparing to backup most probably because backup requires root permissions. Are you sure you granted the app superSU permissions?
[Samsung Galaxy S7 Themes, Apps, and Mods] saiditec:
i have attached the screenshot from supersu

ps: busybox installed from recovery and tested
