So there is this s7 edge (sm-g935FD) and I was tweaking it for a relative yesterday, after rebooting during a system update it asked for a pin number instead of their finger print but they forgot what the pin number was. After a full hour of trying different pins and getting locked out I had to reset the phone to factory default hoping it would fix it as there was nothing important on the phone yet, but I didn't know about this whole frp thing (still using my old note4 so I never really caught up on the new androids or security measures etc), so then it asks for the gmail that was used before but they mistyped the password during registration and didn't bother to add any recovery options for this google account (the phone doesn't even have a sim card yet), so now what can I do? I tried flashing another rom but yeah that didn't fix anything, I seem to be out of options because most methods out there are for the sm-g935F model not the sm-g935FD.
Would there be any problem if I flashed the 6.0.1 rom (of the sm-g935F) on this phone, will all features work fine including dual sim etc?

This is going to be embarrasing story.
I bought new Nexus 6p, and it required Nano Sim card. Being genious me, i've decided to cut my old card and insert it in the sim tray.
It did not work and asked me for sim card's PIN code (which i never set up). Figuring i must have simply broken the card, i decided to boot the phone without any card inside.
Now, when i start the phone, i get the same lockscreen right after Android Logo.
I have tried factory reset, and inserting brand new nano card from different carrier, but none of those it did work.
Using the emergency call dialler I tried entering PUK code *05PUKnewPIN*newPIN# and i recieve "Connection problem or invalid mmi code" error, with or without nano sim card.
Most of the fixes for MMI error are assuming that user can successfuly launch the phone as well.
I have yet to try putting "," or "+" somewhere in the USSD code, this is supposed to "ignore any error messages and perform the code" but i am slightly pessimistic about this.
I thought that maybe the pins were damaged, but they all seem to be allright.
I am a bit conflicted about flashing the image, since i am not sure if unlocking and locking bootloader for flashing will impact my warranty?
I have tried already flashing 6.0.1 stock on top of the stock 6.0.0 the phone came with, but I was still unsuccessful, since i did not enable USB Debugging on the phone and when performing flash-all command in ADB fails due to locked bootloader (that can be unlocked from the settings).
Tried fastboot flash unlock (since fastboot oem unlock did not work at all) as well but it did not work for me.
Based on this, those are the possibilites i consider:
*Try to get MMI error code fixed
*Flash the stock android once i get around locked bootloader
*check the SIM card slot for any dents on pins
*contact carrier and check if maybe it was somehow locked on their side
*Return the phone on warranty and hope that it will be accepted (i expect major hurdles along the way, since the phone was imported to Poland), this would imply that i should not interfere in hardware and software.
I feel that if i get one of mentioned above issues, rest of them should be a walk in the park.
I am really looking for feedback from you guys, since i seem to be unable to deal with on my own.
EDIT: Solved! Found an official google nexus helpline (support.google.com/store/answer/6301411?hl=en) from there someone contacted me and i was given directions on how to solve this issue. If someone finds this thread i needed to do another factory reset
Hi guys
I recently purchased an S4 from an on-line professional seller, the guy apparently owns a physical store but sells some phones on-line
when the phone arrived, I turned it on without the SIM, insert my home's wi-fi connection password, and the phone started to update both apps, and the OS to lollipop
I installed the backup I previously got from my old s3 mini, installed all my apps from playstore, and once I installed whatsapp, I turned the phone off, and than on again, this with my SIM since whatsapp has to confirm my number
The phone accepted my PIN code, whatsapp accepted my number and restored it's backup, but the phone also asked for this SIM network unlock pin
I told the guy what's happening, he told me he would send me a new phone, but I suspect this can go wrong
If that's the case, can anyone here tell me how can I overcome this SIM network unlock pin issue ?
thanks in advance
Regards
Antonio
If the phone were unlocked for use on any carrier, you would never see the SIM unlock pin request screen. Since you are seeing that screen, the phone is not unlocked.
To resolve this, root your phone and downgrade the phone's modem to an Android 4.2.2 version. Find a copy of RegionLock Away on XDA or through Google, copy it to your S4 and install it. Run it. Afterward, upgrade the modem to a more current version, and enjoy.
That's roughly what I had to do when the SIM unlock screen popped up on me.
Which s4 do you have? If it is the i337, region lock away may not work as you may not be able to downgrade the modem.
Hello,
i just got an old a5, the 2015 variant.
I was told it was from an colleague who wanted to throw it away since she wasnt able to surpass her mcafee security stuff and now its mine.
i made a wipe to factory settings and unsurprisingly, i got a clean phone. but it didnt recognize my sim.
so i tried loading the current lineageos on it, su it and everything worked. well..everything except for the sim.
i tried the last two days to get it running but to no avail. tried normal stock rom, older lineage, current lineage, some modem fixes i found here, nothing works. and im nearing the point of just throwing it away^^. samsung phone info leaves most of the csc-code field plank and in settings, i get invalid network mode (-1) in the networks section
Can anyone help me (or the mobile)?
solved it myself. for those who care: i put some ducktape on the back of the nano sim and carefully (theres more pressure on the card and holder) put the whole construction into the sim slot 1.
Even though noone answered id like to thank anyone who cared.
Hello guys. I am not quite new here, but I never registered (or I did but I couldn't find with which email or username).
However, I am having some trouble with Samsung S7 phone.
First of all, the IMEI on the About page is not the same as the IMEI on the back of the phone.
When I enter the IMEI from the back of the phone in IMEI checker, I get the right phone (Samsung S7).
When I enter the IMEI from the About page in IMEI checker, I get some old BLU phone.
Second problem is that I think this phone is not duos, however, whichever firmware I try to flash, I see the SIM card manager in the Settings. Which is weird to me.
Third problem is that the phone won't connect to network. I've tried 3 SIM cards (all 3 of those works on other phones), but this one just won't connect.
It shows full strength of signal, it also shows the phone number of the SIM, however, when I try to make a call, it says "Not registered on network".
The phone should not be locked as my brother said that he used it for some time, then he updated it to the latest OS and then did a factory reset. After that, the phone just stopped working.
Does anyone know what could be the issue? Why the IMEIs are different?
I am quite sure that the phone model is SM-G930F, however, the model number in Settings shows SM-G930FD. Which is again weird to me.
I've looked on the Google to see a picture of the SIM card slot of Samsung S7 duos and mine SIM card slot does not like that. Also, on one slot, it says only "microSD" and on another "SIM". So, I guess it is not a duos phone.
Any advices?
Thank you in advance!
All the best,
Dale
It sounds like somebody has changed the IMEI of the phone and patched the certificate for the IMEI to work.
Once you reset the phone or update the firmware on it, it will remove the patched certificate allowing the changed IMEI.
You will need to look for someone that does IMEI repair / change to get it working for you again I know there is a guy on the forums here that does them for free. Look through the s7 edge sub forums for them.

Well, I already flashed the firmware multiple times with different basebands and versions of the firmware as I thought that the firmware is wrong. Also tried to flash the firmware with Phone EFS Clear option checked in Odin.
Everything else on the phone works.
Sorry that this isnt help but you not alone, I unbricked a Samsung S7 (SM-G930F) after it suddenly just bricked (hard brick/soft brick - same thing). Eventually when I installed nougat on it, and finally wanted to use the phone, i tried a simcard and noticed how it would load all saved contacts but whatever I dailed, it responded "Not registered to network". Checking the model number it is now SM-G930FD but i am unable to verify the imei becuase of missing box. I tried many firmwares (even those that specify its for SM-G930F) but the model number remains SM-G930FD.
could any help plz be posted...
It can be done by repair IMEI, i would like to help you if you'r interested

Hi all long time user of the site but never been registered as never run into issues such as this below.
Recently family member took out sim of their locked three IE phone and tried to put another sim in into samsung j3 2016 sm-320FN model, one thing lead to another got message promoting for pin, even when original sim was put back in which never had pin lock on it and tried different pins which propably triggered some sort of lock on the phone but original sim works fine in any other unlocked phone.
When i took hold of phone i tried to root it and got hit with frp lock, eventually untied it from google account and managed to get lineage room onto it v14- no backup was made of original firmware my naive thinking on this part .
i used odin v3 with twrp 3 wiped cache david data and systems before hand. got it rooted with SUroot, and after then installed latest twrp to get other rooms onto phone.
Now strangest issue is that original sim works fine on any other unlocked phone but putting it into J3 i get hit with network unlock code PUK, at first tried support from three Ireland they thought it was sim blocked after numerous different codes it would return same message network unlock failed, eventually got hold of network unlock code, but entering it in lineage room OS it would say network unlock was successful but there would be no bars on sim, checking reception and signal it would show as none towers discovered and no signal received, following that every time phone is reboot it still promts for same code, figured it might caused issue with current room and downgraded to lineage v13 but still wouldnt see any reception the signal bar appears grey, final conclusion was maybe wrong unlock code was sent so requested another one which came back same as previous from mobile provider.And all repeats if entering code says unlock is successful but no mobile signal detected, tried 3 different roms and always keep getting greyd out signal icon and promt to enter puc unlock code.
In the process managed to wipe completely all rooms from the phone and did DBA backup restore via cmd and managed to get different room running on it RR-OS but same happens each time phone powered up inserting any sim including original network sim promts for code, after entering it, says successful and no bars or signal.
phone is only good to use for wifi browsing now, and im out of options to figure out whats the main reason also cant find original firmware.
Spent 2 days flashing rooms and unbricking phone but seems mobile signal and network unlock fails for unknown reasons to me. tried to list every step ive taken and software used.
If anyone has any idea whats causing this would appreciate any help, even thou phone is old by now but still enough for person that uses it.
