Galaxy S 4 SCH-R970X (C Spire) - Official 4.3 MK6 RESTORE - Galaxy S 4 Q&A, Help & Troubleshooting

As many of you know 4.3 just released on the CSPIRE variant device. I have went through currently 2 phones because they messed up after messing around a bit with kies and "other things". It's like it doesn't want to read from the sim card anymore and refuses to program itself. So with that said here is the stock 4.3 Full restore from sammobile.com so you can hopefully either fix yours or take it to the store.
P.S. They cannot fix it
This will change the Samsung Software to : Official
As well as Recovery, etc, to Official

I got no sim inserted on a loop on my 2nd phone. It would try to activate then kick off and go to no signal and say no sim, then try all again. Go claim the warranty on it! Just as long as you use this file and odin it should go samsung official. They cant say nothing to you for their crappy programming. Because as far as im concerned im not touching it again, and gonna hope they come out with kit kat soon.

Cheers I will do thanks

Getting this thread bumped back to the top, people are looking for it. If anyone has any information as of why the CSpire variant keeps losing its cell data completely. Please help us get a fix going! Thanks

Anyone figure out a reason why the phone would forget the network and not activate??? Causing a useless phone.

[Q] Speaking Of Possibled bricked phones

I may have soft bricked my S4. I was trying to unlock the SIM for it yesterday and stopped due to a problem with getting the MSL so i just continued to use my phone as normal after following these galaxys4root(.)com/galaxy-s4-tutorials/how-to-unlock-sim-on-sprint-galaxy-s4/instructions I got to step 11 and gave up for the day.
I tried to load a different MDL and i kept getting a fail. Now i cant even boot my phone up to the OS.
Any thoughts of even just pointing me in the right direction :|

Sounds like your on 4.3 if that's the case there is no downgrading to anything lower. In case your going to just have to Odin a 4.3 firmware..

If you were on 4.3 already than even Best Buy won't be able to install 4.2.2. I would save my self the hassle and just odin the MK2 tar file from here: http://forum.xda-developers.com/showthread.php?t=2601443 it is the fastest download speed. Then when you go to do the sim unlock, autoprime's thread has a link to an MDC modem only file to flash for the downgrade. You can not downgrade the whole firmware, but you can downgrade just the modem to accomplish the unlock.

No data after flashing update to stock kit kat 4.4.2!

Have a D802 on three uk. Like others went down the route of rooting and flashing cm 11 on my device. All quite straight forward, never had a problem... decide to purchase an s5 so now need to sell my lg. Originally flashed a stock Rom through TWRP and now unable to receive data. Though it was a problem with the rom so I flashed LG firmware through update tool. And have three UK firmware on but same problem!! All toggles selected..data,3G, airplane mode on off, reboot. ..nothing. my 3 UK sim works fine on my s5 so not that. I can get signal fine but no data. Would really appreciate some help as I cannot understand what's the problem. Especially as I can get signal but no data and works fine in my s5 ?

I suspect you didn't do a FULL wipe before flashing....
Suggest you try that first as the APNs for 3UK may be corrupt.
You could try manually setting the APNs but honestly, the Factory Reset option and reflash is easier and fully effective.

Check to see if you still have your imei or not... That's probably the reason, you lost your efs/imei...
If that's the case then if your made a efs backup like you should have,restore it. If not, try flashing stock.

Did you test your sim card and make sure it is ok? Try to out this sim card into another phone and make sure it works? Put another gud sim card into your Note 3 and check if the problem still persist?
Dial *#0011# and check for the RX, TX value? Can you post this screenshot here?

Here the screenshoot
Anybody please
No Network neither
Hi everyone,
i got almost the same problem. My SM-N9005 was on the Standard TouchWiz Rom (4.3, rooted) when i updated to 4.4.2 via Kies and rooted it again.
Now my Phone shows me signal bars but tells me "Emergency calls only". I still have my IMIE.
I reflashed the stock ROM but that did not fix my problem sadly.
Hope you can help me!
UPDATE:
I reflashed the stock recovery once again and factory reset/wiped the data and now it somehow works again. Maybe that helps
UPDATE 2:
It seems like that was just working for a short moment, now after flashing the X-Note ROM (and Kernel) the "not registered in Network" message comes again though i got like 4 bars. The bars just are random somehow and jump up and down every few seconds.
Another Update:
While charging the phone (via PC or via the original Charger) i get a Message that it stopped charging because the battery temperature is too low. I Hope nothing went physically wrong?
your note 3 seems to be unlocked by SPT box or BST dongle
select wcdma/gsm or 3g/2g in mobile network and your network will connect
hope this helps:fingers-crossed:
Thanks for the reply, but my I bought my note 3 unlocked and new from my carrier and havent changed anything regarding the IMIE.
I was thinking about the modem beeing broke down while i updated to kitkat, and therefore flashing a new one. Any ideas on that?

If everything else fails try to write in Odin (or better yet in Mobile Odin Pro) just the modem - and aim for an older version, something like MI6 (present in MI7 firmware) or MJ1. With Mobile Odin Pro you MUST be on stock recovery and it will work perfectly first time, with normal Odin there are some reports that you might need to write it twice or something like that - search around.

Tried that, had the same problems with the MI6, and with the MJ1 it got stock when i tried to unlock it...I was on the Xnote ROM though, Ill once again will try flashing the stock rom...
did you try another sim card ?
Sadly, the sim card works in my Note 2 without any problems... I think its sth that got physically destroyed somehow. When i plug it into the charger is says "stopped charging battery too cold"

[Q] SM-N900V Demo unit or "4G Test Device" Help with Rooting and installing a ROM

[Q] SM-N900V Demo unit or "4G Test Device" Help with Rooting and installing a ROM
This is back story if you want to get to the meat of the problem you can skip this paragraph:
Ok so I've done ROOTING and ROMing a few times now, with my first phone being the Samsung intercept, then the HTC EVO 4G, then it was a Nook color, then the Galaxy SII, and then I bought a Nexus and loved its Vanilla Android goodness.... but that was too small so I got myself a Note 3... I work at Verizon retailer (I'm sorry in advance) since I did a good job last month and the new Note4 came out, the owner gave me the Demo unit of the Samsung Note 3... it has never been updated because the Verizon servers does not see it as a Note 3, they see it as a "4G Test Device" even getting it turned on was a hassle since the system did not detect it as a phone more like a Jetpack I had to start up my servace with my Nexus, but the strange thing is Straight Talk (At&T) saw it fine as a Note 3... Verizon has total control of its updates and pushes them to phones as needed... mine will not update since the server does not know its a Note... SOoo I've gone back in forth from Verizon to Samsung and one just keeps pointing the finger at the other blaming each other saying that the other one is the one that needs to fix it in their system... I'm 90% sure its Samsung since they report the devices as they are made... but I digress the MAIN reason I wanted the update was for the firmware updates, but I have seen them KILL some of the V Notes signals, so maybe this is a blessing... I DO want to put a new ROM on this phone, but I'm a little worried that maybe its "different" then the other Verizon Note 3's and I could brick the device... yet I'd like to try since I am stuck with stock 4.3 and REALLY REALLY want a Google play edition type ROM on my device, something that is totaly Vanilla (GOD Verion has a ton of crapware) with some pen features of course
So since this is a Demo unit or "4G Test device" I wanted to throw out all the numbers here and have some of you check them, and or tell me if you have ever rooted and ROMed one of these... I'm guessing its the same device with some beta firmware or maybe just launch firmware. About phone goes as follows:
Device name: SM-N900v
Model number: SM-N900V
ANDROID VERSION: 4.3
BASEBAND VERSION: N900VVRUBMHV
KERNEL VERSION: 3.4.0 [email protected] #1 TUE Sep 3 23:50:17 KST 2013
BUILD NUMBER: JSS15J.N900VVRUBMHV
SELinux status: Enforcing
HARDWARE VERSION: N900V.07
What I am looking to do is Root then install the closest 5.0 or 4.4.4 ROM to stock as possible without loosing the PEN and remote apps... The google play store has NOTHING good for IR remote apps, but I can live without that... I can't live without using my sPEN... anyway if someone with more knowhow can check these numbers and get back to me that would be AWESOME I'd like to do this right away...
maybe a link or two would be awesome if its a standard Note 3 I'm not asking for a step by step here if its not needed...

I would bet, if you're at a Verizon company store...the dude in the back could flash it for you. Or you could flash it yourself via Odin or Kies. But first, I would simply try a factory reset on it.

I work for an inderect premium retailer and I'm the guy who flahses phones but even kies is not showing an update... That's why I wanted someone with the same phone to check the numbers and see if they differ... Mainly for root and custom ROM and we all know kies and Verizon software won't do that... I can follow one of the many posts on this site to do all this but I'm a bit scared that my phone is different in some way...

Other than the firmware/ROM it's not different. Use Odin to flash to a a release ROM but NOT to the latest NJ6. I would suggest NC4 and then use Towelroot to root.
As usual, it is up to YOU what you do to your phone and if anything goes wrong..no one but you is responsible.
All the info you need is in this thread

Yes, the bootloader is locked. No, you can't use Safestrap until you're rooted. You shouldn't root until you get on a stock release ROM...again, NC4 is your best bet.

If your afraid of bricking learn how to get out of a brick and all recovery info beforehand if that's too much of a hassle don't bother. Honestly you can't get 5.0 or 4.4.4. On note 3 there are no such roms. 4.4.4 is said to be unrootable. There are good vanilla roms but do research beforehand because with you saying you think it needs safe strap tells us you aren't 100 percent sure with what your doing. Yes you need busy box and safe strap and towel root is your easiest way to root and safest. Your numbers are the same don't know why you would think there not? Just be careful. You don't need a paperweight just because you want stock android.

Like I said I've done this a bunch of times, but I was asking since my firmware was A BETA unit and I wanted to make sure it was compatible with the same methods shown on this site. When I wrote this I did not read anything about the Note 3 yet and thats where the safe strap question came from... I wasnt going to read all the forms on it to find out I needed something totally different in the way of rooting or files.
As for making it a paperweight YES it would be a BETTER paperweight then full of Verizon Bloatware I refuse to use a phone with verizon software on it since I do work for Verizon and I have seen what this software is really for. Thanks for the concern but its SUPER easy, I ask all the questions so I don't get hit with anything later I did not plan on, I have never bricked a device yet, not even a soft brick... and I don't plan to.

Perfectly good S4 (GT-I9500) rarely connects to cell service after OTA upgrade. Help!

Hi all, I have a GT-I9500 GSM (Iraqi firmware I9500XXUHPB3, 5.0.1) Galaxy S4 which I am using in the US on AT&T's network. Bought the phone secondhand and have been using it for years - worked absolutely perfect. A while back received an OTA upgrade notification and allowed it. Starting immediately afterwards, phone will rarely connect to the cell phone network (not even talking about data here, phone calls/SMS aren't working!). Once every few minutes to every few hours and shortly after reboot it will pick up the signal, but then within seconds it's back to no network connection.
The update installation was pretty quick so I'm not sure what actually got upgraded - I'm wondering if it was the modem? Anyway my question is: what would you suggest to a newbie when it comes to phones (with plenty IT experience in PCs) as a way to try fixing it? I'm perfectly fine with attempting to flash/root it, though I've never done it before, it seems like a straightforward enough process. However there doesn't seem to be a US firmware for this phone. I'm thinking Canadian firmware/modem might be the best way to go? Should I try the modem first, or firmware? I'd love to not have to replace this perfectly functioning (hardware-wise) phone if I can avoid it - don't have the funds for a replacement right now. Many thanks in advance for any suggestions!
Phone details:
Bootloader/PDA: I9500XXUHPB3
CSC: I9500OJVHPB1
Baseband: I9500XXUHPB1
Update: solved ?
(No, not solved. It looked optimistic for a while, but still no signal)
I followed instructions you will find by searching Google for:
"Update Galaxy S4 GT-I9500 with Android 5.0.1 Lollipop Official Firmware" on HowToRootMobile
(I'm a new user here so it won't let me post a link)
to flash a Russian 5.0.1 firmware.
After a reasonable signal for a short while, I'm now back to looking at the circle with a line across it (no signal).
I have the same case but my s4 is I9505 and i did not do anything to the phone not even root it just stopped working

I am becoming increasingly convinced that this is planned obsolescence. Your phone may have installed the same update without prompting. Needless to say my next phone will not be a Samsung.
