[Q] Intermittent signal on UCLE2 - Phone unusable - AT&T Samsung Galaxy Note I717

Hey folks,
Would appreciate any help here. Had T-Mo and flashed a couple of ICS modems and they sort-of worked (forced it to the AWS band). Moved to StraightTalk and have been having problems since. Tried flashing several modems (pretty much everyone of the ones from the blaze, the SII (989) and the T-Mobile Note leaks as well as the UCLD3 and UCLE2 modems. They either don't work or drop the signal so frequently that the phone is useless.
Running flapjaxx's CM9 RC right now (not that any ICS ROM has made a difference).... I thought that flashing UCLE2 would bring it back to "stock" AT&T but clearly something is messed up. Any help? Please!

Forgot to mention that it isn't that it shows no service but rather the signal drops completely but the data connection is "maintained" (you'll see an H or 3G but in reality you can't make call or use data). Also, I'm using StraightTalk but.on the AT&T frequencies so UCLE2 shouldn't be a problem? (Maybe something stuck from the T-Mo leaks???)

Factory reset. You can do it from the recovery menu or from Settings>Privacy>Factory Reset.

Thanks for the suggestion. Just did a factory reset (twice). That didn't help :-(

Anyone else? Please?

Calling all Canadians! Bell Telus and Rogers users.

Alright so ill start this of by saying, Picked up my note today and loving it so far. Got it rooted thanks to Da G and getting ready to get into roms.
Anyway im making this thread to see if anyone else has tried anything out on the non-AT&T notes(i.e I717M and what not). So far from what i have read people are developing mostly for the AT&T model and saying its not for bell rogers or telus. Now I have been in the samsung world for a while and when it comes to my galaxy there was always ways around this.
For instance most of my ROMs were made for the international version not my bell version. But as long as I kept a copy of the bell modem on my phone i could just flash that and the ROM worked great. So does anyone have a copy of the bell telus or rogers modem for the note? or know if there all the same?
Another example in the galaxy s world was the captivate(Same soft keys as our phones). A person with a captivate could flash an international ROM as long they made a soft key fix when they developed the ROM.
One of the main reasons I ask all of this is because i see so many N7000 ROMs up and running and am wondering what will and wont work.
Look forward to hearing from you all

Bell note here. Been. The at & t roms with no problem.
The only issue that I have is the Yellow Pages crap that appears in my contact list as well as at& t bloat depending on the rom. Easy enough to deal with though.
Aside from that, it's been perfect.
Currently on Team Perfection 4.0.4.

The N7000 ROMs can hard brick your phone since the hardware if the two models are completely different. AS Far as ROMs go, most are based off the AT&T software simply because that's the only ICS leak we have available. But you can use any ROM for the i717 on your Bell Note. I have a Bell Note and flashed almost every ROM and never ran into any problems. Also, Ruth the help ofa lot of people on this sure, I've made stock images of the Bell, Telus, and Rogers Notes so we can always go back. Best if luck and don't hesitate to ask anything.
Thanks for the info, I get mine today and was wondering the same thing.
Yesterday I flashed my Rogers Branded Galaxy i717 with Bell Rom and Kernel and have not 1 issue. I chose to flash the rogers i717 with Bell because I use bell mobiletv and this was the only way to get this particular app to work. Again not 1 issue with data or anything else.
No Rooted device either. Just flashed using ODIN.
I'm currently running the UCLE2 Rom on my Rogers i717. I've noticed that I am not getting LTE where I should be. And GPS connectivity is shoddy at best.
I have a second i717 which is stock that is with me to compare (family member).
I am going to flash the Rogers modem to hopefully correct atleast the LTE issue. Anyone know if this would improve my GPS connectivity as well?
For a number of years I have been buying Canadian phones to use on ATT. Canadain ROMs have less restrictions than ATT. For instance tethering and NFC are not locked. Also after rooting my Roger's Note it took under a minute to remove the Rogers branding. (all except splash screen) I was left with a fully optioned unbranded ROM.
I did want to try the stock UCLE2 ROM out of curiosity but I thought it would not install because my phone was not an ATT I717. How did you install it eugenekim618? Personally I would rather wait for the Rogers ICS version. Keep checking everyday to see if it is available.
I have tried quite of a few of the ROMS on here with my Bell i717M, no problems at all so far, other than the "android.phone has stopped working" at startup, I don't know the cause but it only happens at boot.
DO NOT use N7000 roms! But all of the AT&T stuff has worked great for me.

I followed the posts in the Dev section to Root the phone.
Then installed CWM.
The picked a ROM I thought was good and followed the instructions in it's respective post to install.
I've done a lot of ROM installs for the Dell Streak I used to have and for a Sony Xperia X10.
So I am not totally unfamiliar with the process. Just a matter of getting used to the delivery method for each manufacturer. And then, dealing with the quirks of a ROM that is not 100% for your carrier. Goes with the territory, right?
I tried to read all the posts in a given thread as much as I can.
So you are saying you didn't install the one click odin stock UCLE2 ROM?

No, that doesn't work for non AT&T phones I believe. I tried it, and ODIN recognized the COM, but failed to install. From my readings, can't do the one click install on Rogers since it's not a Rogers ROM.
all custom roms should work no problem, ive flashed tons on my unlocked bell note.
its the stock odin files when you want to make sure you get the proper device.
Hey guys Ive flashed pretty much all the roms I can and some I cant lol. So far my experiances have encountered a few setbacks but nothing substantial and allot if not most of the bugs and glitchs occurring in the first & second gen of roms have been fixed or patched.
As far as roms go as was already mentioned as long as you stay away from n7000 model roms and stick to i727 youll be ok. With at&t roms I always seem to have signal and gps issues. Generally tho I find my signal problem will clear itself up on its own and I believe is actually just just caused by the fresh software 'settling in', even though my signal appears low or fluctuating speed testing always shows Im getting peak d/l & u/l speeds. If the signal doesnt seem to improve flashing the Bell stock modem via cwm always does the trick. Gps usually works great, very fast & accurate, when Im having location issues I use the 'faster fix' app from the market, I dont know about anyone elses experiance but allot of the times theres a problem the gps server isnt set to the normal 'north america pool' but servers Ive never seen before or set to an 'international pool'.
All in all besides signal headaches the only other recurring problems are the inherent and unpredictable random force closing of system apps. It can be pretty random but I find a few constant trouble makers to be at&t software update, android phone. At&t update can be disabled easily under applications in the main settings or I was able to actually remove it using 'rom toolbox's app manager but strangely not with root toolboxs remove system apps. For pretty much all other f/c problems the remedy is a running of 'fix permissions', there are a bunch of ways/apps to do it and Ive found using 'rom manager' works the best meanwhile rebooting into recovery and fixing permissions from there will actually cause more problems.
Ok so those are the most recurring and annoying issues Ive had to name a few but the list is too big to write merely because Ive tried just about every rom right from the sketchiest unstable first releases and everything in between lol so feel free to drop me line if your stuck on a problem cause I might be able to help.
But before I end this novel here lol I just flashed the new 'OnlyOne Beta2' rom from the development section and it runs great. The rom is super stable, very fast and features both fully functional S Voice app and fully functional S Notes app. If you havnt tried S Notes yet its awesome the new functions and abilities totally blew me away so I highly recommend you give this rom a try!

If you had LTE before and lost it through flashing a custom ROM or whatever then try changing your APN to your Carrier LTE network. If you never had LTE when you bought your phone, probably the seller gave you a wrong sim. tell her to give you a 403 LTE capable sim, the 401 is only 4G.

Thanks for the tip. But I got everything running again. I did have LTE to start, and have a LTE sim card. The *#2263* certainly helped. And Flapjaxxx's GPS tools in his ROM helped me get the GPS back up to par.

ok now I just lost my LTE after flashing new ROM from Seraphim Stratosphere. How did you get it back. I factory wipe everything and flash Rogers modem and it doesn't work. How did you manage to get LTE back? btw I have a Canadian Note with Rogers. the Saurom ROM was canadian and I had LTE too.

Try *#2263#
Then force select LTE, and select ALL. That should force the LTE connection. So watch the connection bars. You should see a loss of connection, then reconnect on LTE. Once that is established, do the code again, and just select automatic.

When I try dialing it, it says error can't find USSP or something like that... What does this mean?
Just to be clear that im doing the right thing. I go to the dialer and punch the code *#2263#. How do I "force select LTE"? will something popup for me to select it or should I go to settings/ wireless and networks... I don't have those options in "wireless settings", I only have APN settings...

[Q] 3G not working anymore please help :(

Hey guys I'm on Homebase 4.1 ROM. Phone is unlocked and rooted, android version 2.3.4. I haven't been on these forums for a while since everything has been working great until now. I didn't miss not having 4G data due to being unlocked, but recently Sprint started working on upgraded their towers in my area. We lost 3G data connection for a while and this was supposed to be normal due to the upgrading going on. The problem is that the upgrade is over and everyone else in my family has 3G working again on their non rooted crappy phones, but my 3G never kicked back in. Before I factory reset everything and start messing around with different ROMS i just wanted to see if anybody could point me in the right direction on what I could do or what the problem might be?

try dialing *228 and see if that helps. also try dialing *#*#info#*#* in the dialer and go to phone information. scroll down to the drop down menu and trying putting it into EVDO only mode. see if it picks it up.
Did you have 3G on this rom before the upgrades? Some roms were having 3G problems over the last couple of weeks, but new versions have fixed it.
If that is not the issue then you can try ##DATA#

It was definitely the first ROM i was using being broken. Moved to MOF locked version and everything works fine. 4G is nice too. Setting up all my home screens the way i like it again was a little tedious but oh well.

SGH-i717D Fido Netowork/Modem issues - How to dump NVRAM/force Qualcomm USB Settings?

Hey guys... I just picked up a
SGH-i717
v 4.0.4
Black Star V LF6
LTE Sim, LTE phone, downtown Toronto
I just picked the phone up on the weekend.... It's my first unlocked phone and my first rooted phone. I can't seem to get a network connection (I'm with Fido).... initially I tried a number of APN settings as I browsed through various threads on APN settings for Fido, Android and Galaxy Notes. Over the weekend I had connection of approx 1 to 2 bars, and was at least pulling light bandwidth off the edge network. I called Fido last night to have my network settings reset, and since them I haven't been able to get on my network. It seems to jog between no connection, 1 bar and 2 bar signal strength. Where before it said it was on the edge network it now does not connect to a network.
Calls to Fido show that everything is set up ok from their end; they can't support a non-Fido phone, and they say that they can't guarantee I'll get more than 2 bars connection on any non-fido phone. I was making calls & texts from the phone on the weekend whereas now, following the network reset from Fido, I have no connection. Yet when I Reset to Default the APN settings it populates the fido LTE apn without issue.
I'm lost... could someone please help me out here? I have no experience with either rooted phones or unlocked ones... and my furious googling and thread browsing just seems to be hitting the same recycled threads.
'
Where I'm left is now it's saying 'Not Registered On Network' regardless of the APN setting I use.
You need to check your baseband, or modem. And verify you have the correct one for the fido network.
I Dont know which radio image is going to work for you, but it sounds like the rest of the device is fine.
Check in the general section, and open the "super everything" thread.. There you will find many solution threads, and possibly the correct radio image to get your device running properly.
Radio images are almost always a .zip file that is flashed in recovery. and they are very easy to use. You simply download the image you want to try, and place it on your SD card. then boot into recovery and flash the file....reboot, and test.
You should read up on the flashing method too, and ensure that you understand exactly what you are doing "before" making internal changes to your device.
Additionally, you should make a nandroid backup of your current rom, just in case something goes wrong. then you have the ability to restore the old build and get the phone running again.
read, read, read....it's the only way to grasp this information...
good luck.....g
Thanks gregsarg, that's a great start for me. I will throw myself into that direction. Thanks again for your help.

Well, a slow evening with little progress. After reading much, I ran a backup and tried installing a radio...no error message, just says installation aborted... not sure what tdsp is but I tried downloading and installing goo manager as I read where CWM (which is what I.assume I have now) doesn't work that might, but the installer which was supposed to have rebooted my phone and installed, it did not. This was a good 3 hrs and I was spent for the night. Guess I'll keep plowing away tomorrow.
I created a TWRP backup and have begun flashing different radios/modems... When I try to access mobile networks with the different radios installed none seem to work... .... so far I've tried:
Blaze_4g_LB7_radio_ATTNOTE
icsblaze
ROGERS_MODEM-CWMXLA2
UVLG3modemfori717
VK1_Test
KID_TEST
I've always wiped the dalvik/cache before flashing a new radio. My baseband was i717UCLF6, but after I restored it's now T879UVLG3, which is wierd because UVLG3 was the last radio I installed before I restored. I assume the radio didn't restore and I'm now using a T879 radio as opposed to an i717 radio, but it does not prompt me for a sim card after the restore. I can select a preferred band using the *#2263# command, but none seem to drive a better signal - I'm still idling somewhere between a no-signal and unknown network (most of the time) and 1 to 2 bars. Some of the above recognized my sim and suggested either HSPA, GSM, etc on the *#2263# command, others showed nothing when I did that.
Am I correct in assuming I just need to keep doing this until I find a compatible radio and upon flashing and rebooting it will simply connect with a solid signal? Is there any more specific versions of radios I should be targeting?
Re: SGH-i717 No network connectivity
The modem isn't changed or restored when you restore a nandroid or flash a rom.
If your goal is t-mobile or wind or simplemobile. You have the correct modem installed.
Just go to settings and input your APN and save it. Not every rom has the apn's , and not every carrier automatically sends the apn settings.
Thanks Ranger... my goal is to get it working with Fido... but I'm not sure if that's synonymous with T-mobile or Wind yet
and ngretud
Anyone else have any input on Fido radios? I can seem to find one that works for Ontario....
consistent tomsisu
I've now tried the following radios:
ICS Kid
ICS Telus
ICS.zip
ICSblaze
Kid_Test
UVLG3modem
VK1_Test
Every single one upon reboot leaves me with no connection.,, I don't get what I'm doing wrong here... frustrating. Only way I can get any kind of connection after flashing radios for hours is to flash my restore, which brings me back to the edge2 network. I've tried the Good Blaze ICS newamss and the UVLG3modelfori717...n7005amss too, and while I do get a connection it's virtually the same as the existing crappy 0 to 1 bar, or none with a no-connection symbol.
Any help guys?
Anyone at all? I get weak to no.reception in most places and when I leave the city I have no.connection at all. If it was the radios then why wouldn't trying all those radios show improvement? At this rate I am considering just scrapping the whole thing and getting a phone tats locked to Fido if this is the best there is.
Is this the right forum for this?
Re: SGH-i717D Radio/Modem for Fido - help!
There is no such thing as a Fido radio. You flash a T-Mobile compatible radio (recognizes and uses the two bands/frequencies AWS), verify the baseband in phone settings is the radio you flashed, input the correct APN settings for Fido.
Things to check: your sim works with data in another phone, data is enabled in phone settings.

Thx... SIM works fine, data is enabled. Phone always says unknown under the baseband on phone settings. Pretty confident APN settings are fine, I had them confirmed with Fido. Is it just I haven't found the right modem/radio?
I tried the ones I've found most common in threads: iceblaze, KID, VK1 and even an UVDLE from an S2 thread.... still getting the same low, low signal, 0 to 2 bars with intermittent EDGE:2 signal.
Re: SGH-i717D Radio/Modem for Fido - help!
Ok, so you are sending/receiving data. But is that only using EDGE network or have you connected to 3G data network?
And if you don't have a baseband, the usual remedy is to return to stock at&t ICS rom and reflash your preferred modem.
Have you had better data strength with another device? Maybe two bars is all your location gets.

I know we are conversing privately but I'll continue the responses here in case it benefits someone else. I haven't been able to connect to a 3g data network yet.... Because my unit is an i717D (Telus), do I need to flash to the stock Telus ICS rom or do I need to use the AT&T rom?
I was using an HTC One S, same network but locked to Fido, default OS, same SIM card, and was getting perfect signal and data speeds. I can't see how a place like downtown Toronto would yield any signal issues... like you said it seems like it's a radio/modem issue.
Re: SGH-i717D Radio/Modem for Fido - help!
I hate to suggest it, but one old dependable T-Mobile compatible modem:
http://bayfiles.com/file/6FwV/WrxD5a/Blaze_4G_LB7_radio_ATTNOTE.zip
Its been modified and many have had success with it.
So I have flashed a stock Telus ICS ROM, and along with a stock Rogers radio am getting a baseband I717RUXLF4, Edge:2 signal, and even Fido under network. Getting 1-3 bars signal strength, but still no data.
I tried flashing like 5-7 ICS radios and all of them produced a 'no sim' on reboot. I had to re-flash the stock Telus ICS rom and the rogers radio to get it to read a SIM again...
Super frustrating as I feel like I'm going around in circles never solving the issue here...
Does anyone have experience with Fido modems in Toronto or Ontario? Everything I seen to find.is either for.Telus, Rogers, Wind or Bell...
Sent from my SGH-I717D using xda app-developers app
Another update for no one to read....
Tried flashing the Perfection ICS ROM... got same signal issues, installed the Rogers radio that seemed to work incrementally better with the stock Telus Rom... still floating around the issue of low signal...
There is a shockingly little amount of documentation on Fido setups here... most everything is either Bell, Rogers or Telus, with some Wind and Mobilicity.
Can ANYONE please provide me with some direction here? I think I've done my due diligence and respected the process for new people that these forums demand in terms of reading, research and such... I haven't spammed my issues anywhere else, and clearly seem to be stuck on this issue....
Ok, you need a modem that is 850/1900. at&t is 900/1900. So thats why you get 2G because in some areas you connect with a weak signal.
The Canadian stock rom and the Canadian stock modem for Rogers should work.
In network settings you may be able to select network frequencies. If so, select WCDMA only so your phone stays on 1900.
If that doesn't work, dial *#2263# and find the band selector, and select 850.

[Q] Verizon NC5 rooted to work with T-Mobile SIM

hello, I'm hoping someone might be able to help me with my issue. I was given a Verizon Galaxy S4 that had stock NC5 on it. I have T-Mobile as a carrier. I successfully downgraded/upgraded back to NC5 rooted. Everything seems to be working properly on the phone. Now, I'm trying to get my T-Mobile service working and am having issues. My only options are Global, CDMA/LTE, GSM/UMTS. No matter which I pick I get nothing. I can get into service mode, under UMTS, and bunch of menus down, Network selection, and I can choose GSM/LTE, but when I reboot it doesn't stick. If I choose it and don't reboot I get good GSM, but my data is very sketchy. It jumps from H to H+ to 4GLTE. When I do a speedtest I can get up to 1.5mb/s but it gets stuck when doing the upload speed, and it just seems to be not working right. Although speedtest says I'm getting 1.5mb/s when I do any browsing it seems like the internet is dropping in and out. Is there another rom I need to jump to or something I can flash or change in the build.prop to make this work stable on T-Mobile, hopefully sticking through a phone reboot. This phone was going to be my wife's but I can't give it to her not working "normal".
also, I think I have went through every thread concerning this subject and get any of the suggestions to work, I'm thinking maybe it's because this rom is NC5 and maybe those threads were written for previous versions like MK2, etc.
any suggestions would be greatly appreciated.
thanks!

Modem/Radio resets after phone calls.

Hey guys, tried searching everywhere for this answer. After every phone call my radio resets each time. Started happening on CM11,then on ART MOD rom, and so on. Even tried flashing Stock LG ATT 4.1. I tried flashing different modems, stock att, hybrid , lte hybrid and so on. Any other ideas?
Thanks!
AT&T doesn't support voice over LTE. Every time you make a call, it switches to H+. Its supposed to switch back to LTE after hanging up. I had issues with it under artmod and the other kitkat stock bases.

My question to all the developer here... can anyone help me please? i have LG Optimus G E970 at&t and having serious issue as it is not detecting sim network, everything is running fine except sim network. I was on stock and all things running fine but i installed 4.4 kitkat rom from this link: https://yadi.sk/d/F7yqEV7yaFk8V
then my network not worked, i restore back to stock 4.1.2 but still same problem, no sim detected, i showed it to market developer and they said it is hardware issue while i told them its happened due to installing rom and one have tried on it all things as he was software engineer but no luck, then i gave it to repair shop and they changed its sim jack and insert everything perfectly, but still no network! though one changed in that now when i put sim its not showing but when i eject sim from the jack while phone on the message comes "Phone will restart to use GSM network" and then phone is restarting but same problem , no sim.....!
can anyone tell me exact solution for this? is it really hardware issue or software related? i m stuck up and spent heavy amount on it and still on risk.... i will appreciate your kind cooperation.... thanks in advance..
I have a temperary solution.. hopr it help
I have the same problem and tried everything I could...
If you are in a city area just flash .48 or .54 nexus 4 radio. You get your sim working and can call...
But this will have bad signal strength in Idea 2g network. All the best.
i'm also having the same problem. after every single phone call, the modem resets and the only option is to reboot it. downloaded the latest nightly and did a factory reset and flashed it but it still was re-setting. going to go back to stock.
