I started with a fresh non altered I747m. The first thing I had to do was carrier unlock (PetroCAN sim) and then rooted the phone.
I pretty sure i did a cfroot and installed the newest pacman rom and all worked- just no internet ( the phone and texting worked) so I played with the APN for a while then decided to try a couple of MODEM zips (Rogers and AT&T) and flashed those in CWM.
Downhill fro there- No more SIM, no baseband- no IMEI no APN- could not even create an APN.
Tried diferent 511 ROMS (DU).
so then I did the even more stupid thing and retored the original NANDroid backup and now it is really bad- stuck on the samsung logo.
I did write down the IEMI number and I did check the baseband version (i did the check in like a dos screen on the phone) I747mluf0b1
What should I do now>?? i would be happy to return it all back to stock I really screwed this phone up bad
note: I did do a full nandroid backup before updated to 511 but i saw that there was no EFS folder (an this was when everything was working correctly)
So i think i the phone is toast..
Are you running the latest modem and bootloader?
I suggest you use Odin to flash the latest stock rom for your phone from sammobile.com to see of them either comes back.
I downloaded the correct i747m bell stock version that matches the buildprop I747MVLUFOB1
It is now in a softloop 'SAMSUNG' and sits.
it just came back up
Did you get the phone working?
That got it!!! YEAH!! I been working on this phone for days. All of a sudden the STOCK ROM is the best rom ever!!! hehe
If you have to restore to stock in the future, it is best to uncheck auto reboot in Odin. When you see the word reset in the status window, remove the usb cable, remove battery, replace batter, boot into stock recovery, and perform a full wipe. This helps to prevent the boot loop.

Hi everyone, this is somewhat complicated and il try my best to describe what happened.
My device is a i747m (rogers).
I was running CM10.1 (running gapps-jb-20130812 and CWM recovery 6.0.4.3) for a long time, tried to update to 10.2.
(i messed up on 2 things.I don't think i cleared neither of the cache or data and also didn't have proper gapps which would be 20130813).
After installing 10.2 through recovery, it would just stay in the boot Cynogen booting logo.
i restarted into recovery, since my old CM10.1 zip was still there, i installed that instead, but same thing happened, it would just stay at booting logo.
I had made a nandroid back up from before all of this, and so i wiped data, dalvik cache, cache, formatted system, and i recovered into that, which was a stock 4.1.2 rooted (rogers).
However, nothing worked, only WiFi. I couldn't make any phone calls, send/receive messages, or get data.
I then used ODIN 3.07 to flash the new stock 4.3 rooted (rogers). WiFi worked as before, but i still couldn't make any phone calls, send/receive messages, or get data.
i then re-installed the latest recover 6.0.4.5, and installed paranoid android 4.4.2 and gapps for this version. But still nothing, so i went back to the stock 4.3 rooted.
4 months ago, when i made the nandroid back up, i also made an IMEI back up as well (i did not do a full imei/NV/EFS/IMSI/data backup) , i only had my IMEI backup, so i wrote using "NV items reader writer" the IMEI back onto my phone, and now i can recieve/send messages, and get phone calls and make phone calls. wifi also works.
But my data is stuck in Edge, its extremely slow, takes 10min to download a 15mb file.
so far:
-The APN settings are correct
-my IMEI number in settings menu, matches the one on the back of my phone.
-network mode is GSM/HSPA/LTE
-i have installed the latest modem for i747m through CWM recovery and also tried slightly older versions.
i am pretty much lost and i dont know what i should do.
-rogers has told me to use kies and perform backup and then recovery, apparently that will factory reset my phone.
-should i simply use kies to install the latest 4.3?
-does anyone have the imei/NV/EFS/IMSI/data files? or the full NV file?
-should i install CWM recovery and wipe everything that i can? and re-install stock rooted 4.3?
-should i use QPST to fix my IMEI? <-- dont know anything about this, noticed a few threads.
i have used these threads in all my rooting and so forth.

thank you for reading this long and complicated problem.
same problem, ive spent every minute working on it for a week
Hi folks. Admitted Noob here asking for help.
[backstory]
After many years resistance I finally decided to get a phone. Freedompop's free plan was enough to push me over the fence. Found a nice S3 (L710VPUDOH1) on ebay and bought it. Everything was fine...except the stock rom had so much crap in it I was about to have a seizure. Back in the day I had put CM on a nookcolor so I thought that was the way to go. I consulted with a friend who assured me that CM played nicely with freedompop so down the rabbit hole I went.
[the first sign of trouble]
Installing CM went fine. Odin. Heimdall. I installed the latest clockwork mod touch recovery (6.0.4.5). Then I installed the latest CM snapshot (cm-12.1-20151117-SNAPSHOT-YOG7DAO1K7-d2spr.zip) and the appropriate gapps. Worked great. Nice and fast, good configuration options, no bloat....but it couldn't connect up to the 3g/4g network. Freedompop worked as long as WiFi was on and would not otherwise. Crap. What's the point of a cell phone if I have to have a WiFi hotspot???
Some googling revealed that the APNs were wrong so I tried that route. I was able to get LTE working but never got 3G. I live out in the boonies, so 3G is kinda important. Also found that CM breaks Sprint's PRL auto update which doesn't seem too happy.
[^H^H^H^H^H]
So, I decided to go back to the factory ROM and see how FP worked as I dutifully made a backup before installing CM. Now the SHTF. When I restore from backup in CWM (followed by a factory wipe data and cache to avoid the boot loop) the ROM cannot connect to Sprint's network. Doesn't know its IEMI or much of anything. It does connect up to wifi, log into my google account, get my paid apps, etc....but still no phone.
I installed Kies and attempted to restore/upgrade firmware (non-emergency mode). Kies got to about 66% and said there was an unexpected error. I'm guessing it didn't like the custom recovery and just plain quit on me. Was worried that I'd made a brick but alas I could still get to download mode. </bullet dodged>
I would like to put the phone back to stock (including recovery) but I have no factory recovery image. Does anyone have a recovery image for L710VPUDOH1? Alternatively, is there any harm in flashing the full ND8 onto the phone even though it had OH1 running before? I seem to remember reading things about bricking phones when trying to downgrade....which is in effect what I would be doing.
Any other suggestions about how to get back to stock would be most appreciated.
TIA
You can flash nd8. Nj2 is newer though. I don't think anyone has captured the oh1 tar yet. The only thing you should not do is flash anything before nd8 (pre Knox) like mk3 or older. Which is jellybean anyways so....
Hope this helps.
Yes, thank you; that was exactly what I needed to know.
I have a working phone at the moment so stock is not necessary required. For others that may be interested I flashed in Wicked X 8.2. From there the phone once again knew its IMEI and I was able to carrier reset and get it activated with Freedom Pop.
I recently installed cm14.1 on a Rogers d2can phone and I got unknown baseband and sim card stopped working. I tried flashing different modems which made the situation worse as now even old cm11 roms show unknown baseband.
Can someone please tell me where I can download modem zip file that works for Rogers and for cm14.1?
I recommend flashing the latest KK stock ROM from sammobile.com which will restore your phone back to stock and ensure the bootloader and modem/baseband are matched. After flashing stock and confirming that the imei is correct, then flash twrp, cm14.1, and gapps.
I was downloading from sammobile.com very slow and the download was interrupted in the middle. I will try again later.
Is there a better site to download firmware from?
So I downloaded it and flashed using odin. Flashing took a while but it passed. The phone got stuck on bootloop though.
So I booted to stock recovery and performed a factory reset. Booted again. Now it works!
I'm going to stay on Touchwiz 4.4.2 for a while.
Glad you got it working.
I would not call "staying on Touchwiz 4.4.2", "working" more like opening yourself to a long list of known exploits.
Others are having the same issue (cyanogenmod is dead so I removed the link, hope LineageOS fixes the issue some day.)
Using the last good CM-13 build is probably the best for now.
sim not provision ed MM#2...... easiest fix ....please n thanks;;;;
We'll need more information in order to help solve the sim problem like model #, ROM, etc.
First things first.. DO NOT TINKER WITH YOUR PHONE AT 3AM... sleep is gooooood!
Secondly..
I was stuck Crdroid with "Unknown baseband/imei" (flashing any other rom same issue)
Sim Status (everything was UNKNOWN)
Imei Information (Unknown)
Could not find a modem flash for D852 for the life of me, then stupid me remember DENEROM, and his "Canadian Post of all his workings" ( THANK YOU BY THE WAY DENE)
Now im running nougat so didnt even dawn on me to try flashing a LP modem..
But thats what fixed my issue ( like i said sleep is good )
Just flashing the modem for bell (since bell and rogers use the same crap) (overtop of nougat 7.1.1 cm 14.1) and restarted phone and voila!!
( yes every knowledgeable person is going to be like (duh no ****), but i like to break my phone just to fix it.. as simple as it was either way))
To everyone who tried to help thanks. :highfive: i can breathe now and will be keeping a backup of that modem file just for this issue in the future ( my problem had NOTHING to do with the EFS backup as i had tried 2-3 backups from previous working backups.)
i noticed i did not have the option to backup MODEM (need to find a modded twrp i guess to get that) as 3.0.0.0 does not have the modem backup option (least for me)
Just for anyone who has the same issue with their D852
Here is the link to XDA post by DENE (again all thanks goes to his post)

Now I know this is a huge touchy subject, so feel free to PM me so as this doesn't get misconstrued by any means.
I had my D852 working fine, made the full backup with TWRP, i have all the EFS and all of that.
I flashed a rom, and somehow my IMEI is unknown.. even flashing the (which was working fine) recovery it still has the no sim card / no imei issue.
Now my IMEI is on the sticker on phone underneath battery... is there any possibly way to get this going again. Would PC SUITE work? (typing in my IMEI number on the phone? ) And when i do this do i just have it running normally in the OS or in firmware update mode?
again really sorry for the question.. i just dont want to have the phone without the modem/imei problem not solved.

What ROM do you use?
This happened after flashing Crdroid 1.8/1.9/2.0.
after clean installing from Cm 14.1 (dec 25th).
Im currently attempting to LG flash to stock to no avail.
Did you try to restore just the EFS partition?
Hi all, I have a note 2 shg-i317 that was originally on Bell in Canada. It was unlocked and the aws mod done to it, I use freedom mobile, aka T-mobile in the states.
I was running a Rom for the past 3 years Slimfast 4.4 and liked it. I had tried Nugat on another phone, thought I would try the [ROM][7.1.2][OFFICIAL] LineageOS for N7105
I did the upgrade, broke the root, could not get a few things working, so I decided to restore the Slimfast backup I had just made (complete including modem etc) and everything works except the GPS.
GPS for me is huge, I use it a lot. I cannot lock on to 1 satellite now. Before i was able to lock onto a minimum of 16 in about 30-45 seconds, if outside.
I really dont care if I can get to 7.1 at the moment. I need my GPS back - any troublshooting for getting GPS to work on this phone?
James
I would try to flash the original stock for your phone and country from sammobile. com
Gps should work normaly then. If not your hardware is broken. If it works you can always flash your data back from your Slimfast rom.

Crap, I am posting here, because I did it again. Again not sure how. I tried to run Reserection, and I guess that messed up the GPS.
To put the original stock rom on.. I have to do that through ODIN? I dont remember how I fixed this last year.. Sorry.
Hope somone can help I need the GPS.
James
ps. Used odin 3.09 to flash the original rom... still no GPS
You flashed the latest 4.4.2 room?

The Rom that I flashed to try and restore the GPS was I317MVLUDNF1_I317MOYADNF1_BMC (mine was an originally BELL phone)
But that did not repair the GPS from me flashing resurection.. I THINK did it. I flashed an android 6 and an android 7 rom. (Mokee) but tried to go back to my Slimfast.. and the GPS was now broken.
Basically what I did a year ago.. somehow I fixed it then.. but cannot remember at all how I did it.
James
The note 2 sold by Rogers, Bell, and Telus are exactly the same model and stock roms from these carriers can be cross flashed.
Try flashing the stock ROM twice in Odin with a factory reset in between each flash.

Do you mean boot up the rom.. run the reset in the rom? or flash.. - load TWRP back in.. WIPE.. then FLASH again with odin?
Thanks for helping btw.
James
I have backups (complete all partitions) of my rom.. Slimfast 4.4 from 2-3 days ago.. when I tried this. SO.. if I can get the Factory rom to restore the GPS.. how can I restore the backup.. I saw somewhere that the EFS partition could be left out and that might help? dont restore the modem? how??
James
I meant flash with Odin, boot into stock recovery, factory reset, flash again with Odin, boot into stock recovery, factory reset, and boot into the stock ROM.
Nope, still no GPS lock.. I have the flashing circle (always had) and it will not lock.. I read about where people go into a service mode and rebuild the NV? .. I assume this is something that Mokee or Reserection did.. not sure how.
Any other ideas?
James
what about using Odin or TWRP to put different modems in? does the modem effect the GPS?
tried this.. does not seem to. grrrrr wish I knew how I fixed this.
James
I assume there are no loose wires. Does it get a lock when using wifi? Not sure what else to suggest.
Not sure about rebuilding NV.
No.. I broke it with playing with custom roms.. Liniage was last year.. I did not try that this year.. but tried both android 6 reserection and android 7 Mokee.. and I am pretty sure they messed it up.. I am also pretty sure there was something I did .. easy like load an old STOCK rom and it fixed it.. I was then able to put my slimfast 4.4 back over it and it was fine. Unfortunatly .. not enough people still using this device.. I will have to have patience I guess.
James
So I have tried differenct stock roms, but I think the issue is ODIN will not restore code from a rom image that is HARDWARE based. I wanted to use Samsung smartswitch but they disabled the part of it that allowed you to factory reset the phone, this seemed to work for several people. Many have also reported entering a code and going into a service mode.. there you can do to a menu that will rebuild hardware modules back to default. But I have not been able to get into that mode because it seems to be a touchwiz only option, and I cannot find a factory rom that is touchwiz based for this model.
What needs to be done is a true FACTORY ROM image.. that would revert all software and hardware back to original, but I cannot seem to find that anywhere.
James
The only factory roms that I know of come from places like sammobile.com and they are all based on TouchWiz which is Samsung's launcher.
So guess what? put Ressurection back on.. and the GPS is back.
I cannot get it to work in any KitKat based rom.. but now anything Marshmellow up.. works.. HMMMMMM
