[Q] Flashed stock rom, now no network?

Hi there, new to the forums posting but I read here constantly. I have an sm-900w8 note from Telus in Canada. I was running a custom rom before and decided I wanted to go back to stock before the Kitkat release. Anyway, I flashed the rom from sammobile.com that was for my phone (the link said it was for telus and the file even ends in TLS). So I flash it using odin and everything is perfect, the phone reboots and odin is finished. After that I decided I wanted to clear all my data and apps off the phone as well so I did a factory reset. The next time I turn the phone on everything is working (wifi gps ect) but I can't get on the network and it says I don't have a valid SIM. Also I notice the app packages from telus are not the correct ones and one of them is labelled Bell. So I am guessing the site has the bell firmware for telus as well? This doesn't matter to me but I do need my network running. Do you think it would just be a modem problem? Any information would be GREATLY appreciated guys!

The first and most important question: Do you have a backup of your EFS folder?
If so, you'll be happy. If not, prepare for the worst case scenario.

Seems you have installed a carrier FW on your device and it has SIM LOCKED it. try flashing another.
EDIT: @donalgodon - it's only really EFS when it boot loops and shows Android process not responding etc :good:

Well, that's not exactly accurate. The phone can boot with a corrupted EFS, but you will get no network access (and no IMEI number.)
It's happened to me, so I know it's possible. It's a common symptom of the OP's issues on Samsung devices.

Yeah I am sure I'm not in dire straights yet and lucily I have my backup phone to use for now. I am wondering though, sammobile is the most legit source for stock firmware around, do you guys have any suggestions? Or can I possibly even try just flashing a new modem through odin? (I have never done this but seems easy enough)

True, however, OP states that it was Telus FW that was downloaded and flashed...but it's showing BELL.settings, So the probability of it being EFS is low, it's sim locked the device via the BELL firmware more than likely. Reflashing the correct or unbranded firmware will indeed fix it

Well Sammobile isn't immune to mistakes, but it's rare it happens, they're genuine enough.. You could try the modem, first thing I'd do is test the back up and see if it's the downloaded ROM that has cause the issue.
And yes, you can flash the modem via Odin.

Hey guys... update :
Used #*272 and changed csc from bell to Telus. Fixed instantly!
Thanks for your help guys.

I thought this doesn't work in changing csc code. What's the full numbers you have to input, is it #*272*IMEI# ?

Firmware Cross-compatibility

was just wondering... since G900I and G900F have the same specs would it work if i flash the G900I firmware onto a G900F handset? just asking because i live in australia and i have the european handset G900F

im just a little worried if anything could go wrong. i mean i have backed up everything... EFS, nandroid backup etc.
So worst case scenario it just wont boot yeh? i can install a G900F stock rom back on through odin and everything will be ok?

You will never know mate. The worst case is your device will be bricked ? it all depends on your nerve mate. There are still chances you could restore your bricked phone to normal by using odin, make sure you have a back up of your stock rom
My advice is to use custom rom

only thing that is pissing me off is that I think my handset got shipped with a faulty gps module and now that my knox counter is 1 my warranty is void. so basically everything on my phone works except for gps
Sent from my SM-G900F using Tapatalk

That sucks. I feel for you bro. But just to make sure it is defective. Flash the original region of your phone brand to test before jumping to that unfortunate conclusion

I live in australia and I bought a g900f which I believe is for uk or europe. For australia its g900i and I cannot install the firmware onto g900f. But when I installed gps toolbox it didn't even give me anything. I can understand its one thing to take a long time to get a lock but not seeing any satellites at all is another thing. Ive tried around 10 different gps.conf files designed for australia satellites

Ok, you can do it.
I intended to test it myself first coz I wanted to flash G900F on my G900I in reverse.
Now it's impossible for me coz unfortunately I have been ended up with downloading corrupted firmware due to unreliable internet connection (5 times 2day so far)
If you're desparate to flash G900I, you MUST back up your current firmware PIT file. In case you fail to flash G900I firmware, that PIT file will be used along with your stock firmware to recover your phone to its pristine state.
To do it, please follow this guide , if you're using G900I 16Gb, you could download the PIT file from the OP immediately.
Hope it could help you, please let me know with your attempt. I'd like to help you out in case any thing goes wrong with your phone

ok, so here is the update. since installing G900I firmware failed through odin due to bootloader incompatibility i managed to install it through mobile odin. worked like a charm and even had the telstra bootanimation lol. wifi, bluetooth and everything seemed to be working fine. however my gps is still not working and the G900I seems to have the same gps.conf file as the euro version. i definately believe my gps module is either faulty or not connected to the board properly. is there any app that can tell if the gps module is even there or turned on as no one else is having this problem.

I think you should send your phone to your carrier customer service, they will sort out your gps issue

they said i couldnt anyway because i bought phone from kogan. they said i have to go through kogan.
i can't remember if gps was working before i rooted phone. couldn't have been because everyone else running alliance rom said they havent got problems with gps so it must be a fault unit. im going to take it to a phone repair shop and see if they can fix the gps module.

[Q] Reinstall bloatware before update

Hi my i9505 is rooted and I deleted the Vodafone bloat ware from it, my question is this,.......how do I reinstall the bloat ware before I update to 4.4 or don't I need too (I read it's dangerous to update if you have removed bloat ware from your phone, or is this untrue, any help would be greatly appreciated.
Kinds Regards
PS Before I forget how come some firmware from some sites say 4.4 Vodafone Australia, and some just say 4.4 Australia, does this means it will work with any i9505 or is it just they forgot to put in the carrier ??, my phone isn't locked but had some of the Vodafone bloat ware on it before I rooted and removed it.

@da20valve
Lol. No one forgot to put the carrier. Some firmwares are unbranded and some are branded.
The branded ones work with the carrier locked phones.
Unbranded ones work with the unlocked ones i.e. those who dont have a carrier locking
And it is safe to flash even if you have removed the bloat as when you flash a new firmware everything will return.
And yes. Backup the EFS folder (use the play store to download a efs backup software with highest rating) before you flash even the Official Firmwares.
"If someone helps, never forget to hit thanks ? "

So does that mean since mine is now unlocked even though it was from Vodafone originally I can use the unbranded ones ? (and if its the wrong one will it hurt the phone), also I just downloaded and Jwarriors EFS Backup Tool and saved it to my SD card, thanks for your help, I hit the thanks button.
Cheers

No need to reload bloatware , you can use any stock firmware in your phone as long as is for your S4 model (i9505)

hi mate
This is the latest for Optus
http://www.sammobile.com/firmwares/download/37801/I9505XXUGNH6_I9505OPSGNH2_OPS.zip/
Instructions
Extract (unzip) the firmware file
Download Odin v3.09
Extract Odin zip-file
Open Odin v3.09
Reboot phone in Download Mode (press and hold Home + Power + Volume Down buttons)
Connect phone and wait until you get a blue sign in Odin
Add the firmware file to AP / PDA
Make sure re-partition is NOT ticked
Click the start button, sit back and wait a few minutes
I would do a backup first of your efs folder , any thing important and do a factory reset first.

MAX 404 said:
hi mate
Should I use the Optus one or the one that just says Australia ?, as mine phone was originally Vodafone would it really matter, if it doesn't why do they bother branding them. why don't they just build one for the 4 main carriers, or does the one that says Australia for all carriers.

IMHO you should flash a non branded one.
Why flash the optus one? Just because youre using optus (guessed) does not mean you have to flash that.
And firmwares are branded because they carry specific modem reqirements for the carriers

You need to do a factory reset and if that doesn't sort it try a different firmware.

S7 edge / s7 edge Dual sim G935FD = same firmware ???

I have the G935FD from UAE.
I have searched firmwares on sammobile but I think this is the same of G935F.
Could you confirm me ?

Yes it is. I even use DBT firmware for 935F in Germany, where no 935FD is on the market.
*SM-G935FD*

my battery life is not very good. i would like to update to the last firmware... and it's a little bit warm...

Which firmware are you using? I had very bad battery for the first 2 charges, barely 3 h SOT, third charge gave me good 7h SOT, so be patient and do use the app package disabler for samsung where you could disable services that only root can disable but without the need to root !!!

Now the firmware contains 5 files inside.
The question is how the CSC file, what use?
With "HOME" in the name or the other?

I have used the normal CSC (including PIT-file?) and not the Home-CSC (excluding PIT-file?) and everything works like a charm.

If you root, you trigger knox -> No fingerprint, no KNOX security, no Samsung Pay...and it's permanent.
Samsung has implemented region restriction to almost all newer galaxies. If you are gonna buy from UAE and use it elsewhere, make sure you make/receive call for cumulative duration of at least 15 minutes using the middle eastern SIM card to remove the restriction. It's just a measure by Samsung to prevent grey market.

[INSTALLED] SM-G935U over SM-G935T Firmware? What's so good about Un

Hello XDA Family
I recently flashed G935U Firmware *4API3 over G935T *4APIA, last night to be precise and right off the bat I must say that INDEED IT IS AND FEELS FASTER THAN STOCK *4APIA. You can just UNINSTALL instead of DISABLING bloat apps.
But other than the debloated firmware, what can we get about this Unlocked version? What is so good about it? Why SM-G935U over SM-G935T Firmware?
Pros & cons? Would you go back to stock?
Running September patch.

I'm still on APG1. Do you think it's safe to flash the API3 U firmware over it without taking t-mobiles PIA OTA?

I believe you would get the whitepages and tethering functions back.

No question is dumb my friend.
I downloaded the SM-G935U TMO ....the one for T-Mobile as there is an UNLOCKED version for every US Carrier.
I heard AT&T and T-Mobile are so far the best firmwares of them all.
Try downlading the SM-G935U(ending with *4API3*)
1. Make sure you use the LATEST ODIN VERSION (3.12.3)
2. Latest SAMSUNG USB DRIVERS (v15.61)

You have to FLASH ALL 4 FILES MY FRIEND.
AP, BL, CP, CSC ALL THE WAY!

Make sure you do a backup of what yoh currenty have, flash the G935U Firmware with ALL THE 4 FILES IN THEIR SLOTS.
After that, make sure to boot into recovery mode menu, wipe cache + data...reboot.
Try it.

I may try it again over the weekend.. So far since going back to the tm firmware ,my battery drain is gone.. battery life is superb once again. Thx for that info.. i flashed all 4 accordingly. Did not wipe cache + data.. that may have been the culprit.. we shall See..

im sorry for the confusion i flashed all the files i thought i implied that just tried to paraphrase but yes i flashed all 4 files over my September install without factory reset and i did not go into setting and wipe dalvik cache either but the system did that automatically anyway IYO what should i do now i don't want to start all over again ( re flash tmb firmware then factory reset then flash U software Then set up again ) what should i do you think?

If u had an iphone before u have to unlink ur phone number from imessage. Something like that happened to me that was not getting messages and that was the reason

Installed CSC as XAA variant, so far so good isnt laggy as tmo stock will report battery life after few days, text messages, data and calls are working fine.
Thank you OP

Maybe add the correct APN? for msg?
