[Q] Poor cellular signal - AT&T Samsung Galaxy Note I717

Hey, everyone.
My friend and I unlocked his Note and he switched to T-Mobile. We played around with flashing different radios and ended up with one that gets decent signal, but nothing that's satisfactory. Are there other radios that work on this phone? Can it be any T-Mobile radio?

have you tried different modems? from what I have read, many times that has more to do with it than radio

well I am definitely no kind of master of everything here. I think usually, I may bring up something somebody didn't think of and it will spark the correct answer from somebody else. but I think many times I am on the right path.

What is the difference between modems and radios?

The difference is that one is spelled "modem", and the other is spelled "radio". And I think you already knew that captain

Charging flex cable
Hello, I purchased a i717 off eBay and my luck i figured out after I got it and had no cell signal accept in a few real good hot spots. I figured out the seller replaced the charging port flex cable... I read that the part numbers matter a lot on this phone andhe don't have the original now.... I am trying to get this figured out it as on the case v0.3 so I'm guessing the one I needed is a rev 3.0 and I can't find it anywhere or a rev 2.0 for that matter... So does anyone have any idea how to tell which one i need and do they actually say rev 2, or just the second numbers are different but it says rev1 in the top line.....I've checked the antenna cable and it charges fine..... Please help........:crying: I sold my iPhone 5 and found this amazing phone that I can't use :crying:

Figures I get 1 reply on my first post and its someone just out to make someone feal bad...have you ever had this issue? I joined this forum looking for help not to be made fun of thanks. if I was unclear I'm sorry let me clarify....
There are 2 sets of numbers on the charging port flex cable.... I find a bunch of rev 1.0 cables with a few having different numbers for the second set of numbers on the cable. I read there are 3 revisions of this cable rev 1.0 rev 2.0 and rev 3.0.... So how can you tell which rev it is will it say rev 2 or 3 in the first set of numbers or is the second number how you tell?
So in short 1. How can you tell which rev the cable is?
2. How can you tell which rev the phone should have if you don't have the original part?
3. Where can you buy th part you need if it's rev 2 or rev 3 ?

If in doubt, buy the latest revision. It should be backwards compatible. To know for sure, contact a samsung service center and ask them.

JTAG PINS for vibrant

It's what you use to fix/base flash bricked phones.

Doubt it is bricked. Maybe hardware dead, but not bricked.
Unless he tested something for you that you were not willing to test.

Nice. Please do. Then we can finally settle what chip is running and if there is FM hardware or not. Hope you have a nice camera! I want HUGE and close pics
BTW, what you think the odds are the usb doubles as jtag? Briefly going through all the code, I could have sworn I saw stuff related to ttyS0, baud rates and all. Maybe just need the right pinout.

Would be interesting. Im going to take the pics as soon as i can. its weekend. prob monday or tuesday.
if you think it works as TTY. Its possible. I dont see any pins on the boards. Thats why i asked.
JTAG and serial console are different things. jtag won't show in the kernel, it is a physical set of pins for direct access to the cpu and/or flash.
The serial console might be available via usb (eg on the g1 it is, with a custom cable) but it is only helpful for kernel debugging - if a kernel is broken, but not too broken, you can get logs out of it while it starts up..
Ok. I made an attempt at taking the pics. This is my first time to do macro shots
If anyone can give me suggestions to make better. Let me know.

Indeed. But seeing the tty stuff in the kernel just made me think that if the usb can double as a serial port, it might also double (triple?) as an easy to reach jtag port. Then again, I dunno how many cables a jtag needs. iirc, microusb has 5.

[Q] Which revision of USB flex cable should I use?

A very small amount of water got onto my charging port, and now it won't charge at all - the phone itself works fine, but it won't charge via cable or even recognize the phone when i plug in the USB->PC cable.
I'm thinking of replacing the USB flex cable, but I've read many posts on here about people having signal problems after installing theirs - and I see there's various different revisions being sold on ebay (revision 1.3, 2.0, 2.1, 2.2 etc etc)
I've seen some people saying that even installing a new usb flex cable that has exactly the same revision number printed on it, gave them issues.
Can anybody please help shed some light on this for me?? Is there a 'best' revision, and if not, how do I know which I should buy? I really don't want to buy one, install it, and have problems.
Thank you so much..
I got the 2.2 version as that was the same as my phone originally had.

So that worked fine, and you didn't have any signal problems?
I'd really rather not open my phone just to see what revision number it has inside it.
You should buy the ones that people said have worked.Some of the posts have sellers name from eBay.

Thanks, but surely there's a reason for the various revision numbers? How do I know which to use? I would normally assume that later revision is better, but this doesn't seem to be the case...?

2) If ur reluctant with the above then go with what other users have already done and wrk'ng fine for them

Thank you. I guess 1) is the best option, it's just that I've read posts from other people experiencing issues with the signal becoming weak, even after replacing the board with exactly the same revision.
Thats not right pal.If you have read several threads(like Ive done),youll see people have bought the same revision as they have and its still faulty/doesnt work.
Some have bought blue boards instead of green and used different revision numbers.
Some sellers sell ones that work,and others dont.
The most common thing is this:
Peoples phone doesnt charge,so they buy new board and have signal problem.They put old board back in and signal back to normal....but no charging obviously.

Yes, exactly. So I want to know why people still experience problems even when they use exactly the same revision number. Obviously I don't want any issues, so I want to buy the right version.

[Q] Signal Problems. Caused by hardware problem?

Dear Forum members,
I know this is a very common problem/ question. But looking through the forum I was not able to sovle this problem myself.
So the problem is I have no reception neither in my flat nor at work. This makes my phone kind of useless.
I recently tried out several modems but could not achieve anything with that.
My gf has a I9100 as well with the same provider (O2, Germany). She has pretty good signal quality in our flat while my cell has none (even with exact same baseband phones next to each other).
So I can only guess that it is a hardware issue. What do you think?
Btw, outdoors of our building I have 100% signal H+ (I'm living kind of in the middle of Berlin).
Your help is very appreciated here. Cheers,
lennart
I have a I9100 with
CM 10.1

Seriously, this issue started when? It's just weird that you don't get any signal indoors, but your girl, with the same device as you, does.
If warranty isn't voided...I'd pay the store a visit.
Could there be a problem with the antenna? Would be worth the try to buy a new one?

Is your warranty voided? How long has it been since you got any signal at your place/work?
Did you change some part recently, like speaker/usb flex? Did you try to use the external antenna?
Don't even dream of messing with the antenna unless you're absolutely certain your warranty is no good (damage to the phone caused by normal use/misuse or warranty period expired).
If your warranty is good, use it.

Okay, full story: I bought the phone used 2 weeks ago from some guy. I tested it with him outside. Worked great Took it home and recognized that signal quality is bad. No warrenty at all. And I found that 1 of the 7 screws was missing. So I'm not the first who opened it I guess.
Maybe something was exchanged but I don't know. Think it would be of any good to exchange speaker/usb flex?
New ones are below 10€ so I could give it a try.
Thanks for your replies!

Is My SII a Prototype or a Fake Phone?

Hi guys I was having issues connecting my new SII to my att network. I checked the imei using the *#06# and it came back with the generic samsung imei of 00499010640000. When I went to check behind the battery cover it also showed the same imei printed there.
This seems shady as I know that imei is the generic samsung imei when the efs folder gets corrupted. It is worrysome to see the same imei on the back of the phone as I think this means this phone is fake or a prototype.
I bought the phone on ebay from a chinese seller and I've already been refunded my money and told to keep the device by ebay since it doesn't work and they also believe it is fake.
What are your thoughts? The phone never connects to 3g but it will connect over gprs and load pages. However it won't make calls. Very strange. By the way I've flashed stock gb ics and jb and they all work with exception of the modem.
Thanks

It doesn't have to be a knock-off... But it could be some sort of a prototype or a development model. There is no way in hell this phone is from a regular production run - not with the IMEI sticker like this. And the hardware design differences are quite significant from a standard i9100. True, all manufacturers always leave their options open to change the specs or design without notice, but how many people have actually seen this variant IRL or even on the photos? "Fake" or not, this is definitely an oddball...
Could this be the chinese variant of the gt i 9100?

You could but you won't, it's not strictly legal.
You've been refunded so keep that device and do whatever you want with it, who knows, maybe you'll need some parts one day.
Now focus on getting an I9100, the real thing
You could also contact samsung and see what they have to say about a what-is-seems-to-be legit I9100 with a generic IMEI (Branded under the battery).
