[Galaxy S 4 Q&A, Help & Troubleshooting] sbushnak:
Hello all, I need some help in regards to my Samsung GS4 I9505. Sorry for the long post!

I bought this phone off eBay about a month ago and only did a quick test to make sure it was working. It is a used phone but in excellent condition to replace my old 9505.

Now 2 days ago I had some free time and wanted to check the phone more thoroughly before I transfer my data from my iPhone to the new to me 9505.

The phone had the stock ROM from Hong Kong (TGY). I9505ZHUFNL1 I think if I’m not mistaken.

I realized a few weird things in this phone.

1.	First it had the AT&T ringtones installed, and 2 AT&T bloatware apps installed. I thought maybe the seller put them their thinking that I had AT&T.

2.	Second, in the ABOUT PHONE, Model # shows as I9505 but the build number shows as I337UCUFNB1

Now I wanted to install a new stock ROM and root, process has failed in ODIN. (PS) I have flashed and customized my old 9505 a lot and have some idea on what I'm doing. I am still a newb though!

Currently I can get into Recovery and Download Mode but my S4 does not boot up. It gets stuck on the logo “SAMSUNG GALAXY S4” As you can see from the pictures below it shows PRODUCT NAME as I337 in DOWNLOAD MODE and shows kot49h.i337ucufnb1 in Recovery.

I am trying to flash stock ROM but ODIN has failed. Tried TGY, DBT and even AT&T ROMs and nothing is working. Tried to use KIES and nothing, went into recovery and deleted everything. Still the phone is not working.

I also got this AT&T message about “System software not authorized by AT&T” but that message is gone now after I flashed AT&T I337 Stock Recovery.

I have searched all over the net and these forums to try to get the phone back up, so far nothing is working on my phone.

Attached are pictures showing model #s and an error I got while trying to flash stock ROM.

Any ideas or suggestions on what to do next? Thanks in advance
[Galaxy S 4 Q&A, Help & Troubleshooting] Joku1981:
I think is a refurbished device. But try to download, unrar and flash this firmware via ODIN: HERE. This is the STOCK firmware for your i337 (in theory). Tell me how it went and good luck :).
[Galaxy S 4 Q&A, Help & Troubleshooting] sbushnak:
Thank you. Downloading it right now. Which Android version is this?
[Galaxy S 4 Q&A, Help & Troubleshooting] Joku1981:
It's android 4.4.2. We gona confirm that you have a refurbished device or no. Tell me too what errors appears in ODIN in case you have them. Dial *#1234# when the process of installation finish and tell me if all go ok.
[Galaxy S 4 Q&A, Help & Troubleshooting] sbushnak:
Thank you soo much!

Some good news. I flashed the file and now device is up and running with the AT&T ROM. No errors.

AP: I337UCUFNB1

CP: I337UCUFNB1

CSC: I337ATTFNB1

Even phone model shows as I337
[Galaxy S 4 Q&A, Help & Troubleshooting] Joku1981:
Be relaxed then. You own a SGH-i337, no a GT-i9505. The previous owner was flashing wrong firmware for sure. Enjoy your "machine" and Merry Xmas. :highfive:
[Galaxy S 4 Q&A, Help & Troubleshooting] sbushnak:
Thanks mans for your help and Merry Christmas. Well I am not relaxed since I need a I9505 not AT&T. I'll be moving to the Middle East soon and so the AT&T will work there but I cannot use 4G LTE.

So he most likely even replaced the sticker under the battery to show I9505. I checked the IMEI under the cover and using *#06# and it matched. I checked IMEI online and it shows the model as I9505.

What the heck did the seller do to this phone? Salvaged some parts from AT&T model and installed it?

Just to do a small experiment, I'll get my friend's AT&T SIM card which have LTE and tested it on this phone to see if I get LTE or not.
[Galaxy S 4 Q&A, Help & Troubleshooting] Joku1981:
1. I was telling you before is a refurbished device. They mix parts of differents models for create one new monster, like Frankestein :D.

2. I checked the original SGH-i337 and it has LTE. Take a look for yourself: HERE
[Galaxy S 4 Q&A, Help & Troubleshooting] sbushnak:
I'm such an idiot! I missed the part about you saying it is a refurbished model. Well this is first for me knowing that they can build Frankenstein S4s! This particular phone is quite misleading.

Also yes you are right SGH-I337 has LTE but will not work in Middle East since we use different LTE frequencies there.

I'll get back to you after I do this small test just so I can feel a little better!
[Galaxy S 4 Q&A, Help & Troubleshooting] sbushnak:
Joku1981,

I just used my friend's ATT SIM card and it connected to ATT's LTE network. Pic attached.

Thanks for your help. I'll contact the eBay seller and see what he can do. Worst case scenario I'll try to sell it on eBay.

and Merry Christmas!
[Galaxy S 4 Q&A, Help & Troubleshooting] Strephon Alkhalikoi:
How much did you purchase it for off eBay?
[Galaxy S 4 Q&A, Help & Troubleshooting] sbushnak:
Bought it for $250. came with 9505 box, original charger, usb cable(looks non-oem), manual and headphones. It is also unlocked. Tried a SIM from T-Mobile and it worked.

Hello everybody,

I'm not sure if this is the right section which i'm posting in, but as i couldn't find a more suitable place I'll ask my question here.

2 Weeks ago i acquired a Samsung GT-I9301I Phone, i'm completely new to Android as my Company phone is a BlackBerry. The Phone itself seems really good but the whole Software Bundle (Bloat-Ware) that come with Samsung Devices were pretty annoying. So i started some research on the Internet concerning Custom ROM's and found a Thread here with CyanogenMod 11 suitable for my Device. So i flashed it onto my Phone, and i'm quite impressed of the work [MENTION=4947931]Rox[/MENTION] has done.

Yesterday i had a conversation with a Friend of mine in Germany who works for Samsung Mobile, especially the Cellphone Repair Section. I told him what I've done. And he told me that sooner or later my Wi-Fi Module will stop working because the CyanogenMod will Damage/Destroy it. He told me that they receive lots of Devices with this problem and that it is definitely a problem caused by that Mod.

ACTUAL QUESTION:

Has anyone encountered such problems or heard of it before? Would be nice to collect information on this, if it's really caused by the CyanogenMod. And if, then maybe we together can relay the information we gather to the CyanogenMod Team for further discussion and problem solving...

Thx ahead, Steve

Whelp, I've used CM on my old HTC Sensation for years, never encountered any problem with the modules for sure :/

Is your buddy really serious? Because I haven't heard about a device damaged by that
[Off-topic] SKolberg:
Hi,

indeed he's serious he won't make jokes on that.

Before me posting here and opening this thread I've also done intensive search on the internet, but i couldn't find anything concerning the mentioned problem.

So the question now is: WTH did screwed those devices he's talking about. And if you're saying that you also never heard of something like that and you're using CM yourself for several years, then it brings me to only one answer.

Rookies with no experience are flashing their devices and that maybe because of missing knowledge/understanding something gone wrong during their attempt's to flash the Custom ROM's...?!?
[Off-topic] karandpr:
WiFi Modules need to be compiled with kernel.

If those aren't flashed after flashing a mod or custom kernel, WiFi won't work.

If a rookie won't flash kernel modules then it's his mistake.
[Off-topic] SKolberg:
Hi..

That's maybe really the reason. I'm using CM since 3 day's now and haven't encountered any Wi-Fi problems except a maybe weaker signal strength.

OK 3 day's isn't that long so I'll keep my eyes and ears open, and will follow this "Rumor". As anything happens I'll report it here.

Everyone a Merry Xmas!
[Off-topic] hanisod:
I don't believe you'll encounter any problems, it's just important to flash the right files, is all

And no, signal is not weaker, AOSP has different parameters for measuring signal strength, and I believe it's more accurate than manufacturers ROMs (saw this info somewhere on the forum, don't remember where)

And merry Christmas you good XDA user
[Off-topic] Planterz:
How can software physically damage hardware? The only way I can think of actually damaging the wifi module is if the phone is dropped, gotten wet, or run so much that heat fries.
[Off-topic] SKolberg:
I'm thinking the same concerning the Overstress / Overheating otherwise no idea. Working in IT business myself and that's the only reasonable explanation for Hardware damage.

The other question is if it's software related than it's only possible as mentioned before, that the module driver isn't correctly compiled / implemented into the kernel. And therefore the module just isn't working instead of destroyed.

As those devices aren't being repaired by my friend cause of void warranty, it's still an open question if the modules Hardware damaged or just aren't working...
[Off-topic] BlackSoulxxx:
Well, unless your friend is completely a idiot (no offense...) software can't do harm to hardware...Overheating may cause real issue but in reality I have owned dozen of devices from old HD2 to new Z3, all run custom ROM but never encounter single hardware error, only some minor button damage....

[G 2014 Q&A, Help & Troubleshooting] ramiwi:
I assumed that Moto G 2014 global gsm model is XT1063 but my phone which was ordered from amazon (http://www.amazon.com/Motorola-Moto-2nd-generation-Unlocked/dp/B00MWI4HW0) as global gsm has xt1064 label on its back. Google play devices also identify it as xt1064.

The box has the 2 following sticker labels:

One label says: "B00MWI4HW0 Global GSM Unlocked"

and the other: "XT1064(MOTO G) (2nd generation) Model: 00503NARTL"

So it seems to be a global gsm XT1064.

Is this normal? Can I manually update to lollipop with the xt1064 ota files?

I think this is the US version and not the Global version.

The global version is "retuglb" instead of "retuaws"
[8525, TyTN, MDA Vario II, JasJam General] SneezyRobot:
Hi all, this is my first post on this forum but I've been reading for a while to educate myself.

I've got a Herm200 that I've been trying to troubleshoot but to no avail. I'm fairly certain that it has a hardware problem but I haven't been able to isolate anything.

Here's whats happening:

Occasionally the screen will come out of stand-by all white. This will also happen randomly if i touch the screen to perform a command. While the screen is operating, sometimes the buttons on the face will stop working, however the buttons across both sides will continue working just fine.

When the screen turns all white a soft, hard, or stand-by cycle will not always bring it back to life. The fact that the hard reset wont always fix the problem makes me think it's a hardware issue since the phone will boot-up with the the all-white screen.

This is incredibly frustrating especially since HTC wont accept any warranty claims in the USA on the Tytn.

At first I thought this might be a problem with the ribon connection between the screen and the base but i haven't been able to confirm or discount anything at this point. I have yet to find a way to consistently reproduce or rectify the problem so it's very hard to troubleshoot.

I pretty much have to take a second phone with me everywhere right now just incase i need to make a call. Please help! Has anyone ever encountered such a problem?

Thank you in advance!
[8525, TyTN, MDA Vario II, JasJam General] barncourt:
Hi. This sounds very similar to a problem that I experienced with a HERMES100. I bought the phone off someone on Ebay recently - someone had obviously scrambled the radio on it. I re-flashed it, and it sprang to life. However, after a couple of days, I experienced a problem where occasionally the LCD would stop refreshing, all the pixels faded away leaving only a white screen. Under these circumstances, some of the buttons on the phone stopped working. Turning phone on/off sometimes cured the problem, or it would require the occasional hard reset. This would happen once or twice a day and I suspect thats why someone tried to re-flash the phone.

In the end, out of curiosity I took the entire phone apart, put it all back together again and now there are no more problems!! Totally fixed!

My suspicion is that it was one of the ribbon cable push connectors on the mainboard - possibly not seated properly, or a bit of dirt contaminating the connection. Obviously when I took the phone apart I must have re-seated it.

If you are planning to take your phone apart, please exercise considerable care because some of the parts are very small and easily damaged. I would recommend buying a proper kit to take it apart. I bought mine for about £5 off ebay. Particularly useful are the plastic spoon "wedges" used to gently prise open the case after removing the screens. Don't use a screwdriver - you will scratch the case.

Good luck.
[8525, TyTN, MDA Vario II, JasJam General] SneezyRobot:
wow... that sounds like exactly what's going on here, I actually even tried to disassemble it lastnight but didnt have the right driver set. thank you for the advice!

I'll look for one of those sets but what would you search for if i needed to find it?
[8525, TyTN, MDA Vario II, JasJam General] SneezyRobot:
Thanks again, I just got a set off of Ebay. Hopefully it'll be here next week :)

With any luck it'll be a connection issue.
[8525, TyTN, MDA Vario II, JasJam General] thewall:
I have had the exact same problem. Because I got the Tytn through work I made our IT department handle the issue and I am currently waiting for a replacement and to find out what happened.
[8525, TyTN, MDA Vario II, JasJam General] mattytj:
Yep, it looks like the problems the OP is having are very similar to the problems we've been having over in this thread:

http://xdaforums.com/showthread.php?t=291027

I'm beginning to think it's a hardware problem as well but not entirely sure.

People in the above thread mentioned that using the scroll wheel a while then moving back to use the D pad fixed the problem (very briefly in my case.) Once I use the center D pad button again it locks the hardware buttons under the screen until I make my device sleep and resume.

Somtimes rather than making all the front hardware buttons unresponsive the issue is that once I use the Down Dpad button I can't use the up button. Pressing up will make it go down, as will pressing down (at least that's working :p).

Regarding the white screen - this sometimes also occurs. I can force it to white screen by putting a little pressure on the silver panel surrounding the top, right and bottom of the screen (I have an imate jasjam). Randomly when there's no pressure on the rim and I wake it out of standby, it has a white screen that can only be fixed by turning the screen off and on again.

Finally, the LED indicator seems screwy. Sometimes it never flashes. Other times it flashes sporadically (uneven intervals - we're talking maybe a minute between one flash then seconds before another). When I charge it sometimes the LED doesn't come on but nevertheless it charges. Sometimes if the LED is on it never turns green to indicate a full charge. Yet other times it comes on orange, turns green, then never switches off!

Is it possible that

a) The hardware button problems.

b) The white screen problem.

c) The LED problem.

are all related to some kind of connection going loose? Why would the hardware button problem be temporarily fixable with use of the scroll wheel if this were the case?

The other thread has fallen silent. I'm hoping that some of the gurus in here can offer some input here, even if they don't know the answer but can formulate an opinion. I know very little about these devices. :(

Thanks in advance guys!

PS - don't really know if I should start another thread, I've posted here as it seems like very much the same issue.

Anybody any idea? advice?
[8525, TyTN, MDA Vario II, JasJam General] klasikahl:
I had a similar problem with my HERM100. I didn't mess around with it too much, I just had Cingular replace it out of warranty exchange (thank god those original ROMs are on the wiki :)). I did notice however that after doing a master reset, the screen would function again although I haven't messed around with it too much. I got so frustrated with removing the battery for 5 minutes and STILL powering on with a white screen that I just threw it in my back seat until the new one arrived.
[8525, TyTN, MDA Vario II, JasJam General] dmxl:
I don't have these screen issues. I only have hardware button problems. It's so damn frustrating! I already own a replacement.

I just received a call from my girlfriend. I wasn't able to answer the phone with the buttons, only with a screentap. I also wasn't able to close the call with the hardware button. Since the side buttons work, I went to settings -> phone, closed it, and there we go. The hardware buttons worked again.

Why the heck is this? I truly hope for some wizz out there with some advice, since HTC would only tell me to send it back after replacing it with a new TyTN with same issues.

Regards,

DM.

HELP!!!!

This is my first post as I've so far managed to cure all my issues from just reading the forum. However, I am now having a similar problem with the white screen.

I have a cingular 8525. It fell and the following day the call and end buttons remained lit and wouldn't turn off and they also wouldn't work.

I soft reset, nothing, I then removed the battery and when I turned it back on, there was a white screen and the buttons below still don't work.

I have read the other posts on this issue, but I need help on exactly what kit to buy to reconnect the screen cable and instructions on how to do it as I've never taken apart a phone before, although I have dabbled with other electronic devices.

Your help would be much appreciated, as I am in Jamaica and there are no technicians here who I trust to help.

Thanks in advance.

Below are links to 2 kits I'm thinking of getting. Is either one better than the other?

[8525, TyTN, MDA Vario II, JasJam General] MikeChannon:
Both kits look ok. PDA one tells you a little more but the basics appear to be in both.

I'm curious though you soft reset and took the battery out, but have you done a HARD reset? I would always try this first before dismantling.

Mike
[8525, TyTN, MDA Vario II, JasJam General] dmxl:
In my case, they also are always lit up when the screen is also active.

And no matter what ROM version, they occasionally stop responding. Side buttons keep working.
[8525, TyTN, MDA Vario II, JasJam General] CINGULAR IN JA:
Thanks for the response.

I couldn't do a hard reset because the buttons weren't working.

I have made some progress with the phone now. Found a tech guy who looked at it for me. The white screen is gone, but the buttons still stop working from time to time.

All the connections seem ok.

Is there anything else that could cause the buttons to malfunction?
[8525, TyTN, MDA Vario II, JasJam General] MikeChannon:
Nothing obvious.

Have you got applications installed that you have loaded - could be one thats playing up.

Have you now been able to do a hard reset?

If taking device apart and reassembling improved things it does suggest hardware though and might be worth double checking all those multi-connector blocks for good connections - i.e. take them out and in a few times to ensure any oxidation on contacts is removed.

Mike
[8525, TyTN, MDA Vario II, JasJam General] CINGULAR IN JA:
Thanks Mike.

I will give that a shot.

I haven't installed any new applications recently, so I don't think it is a software issue.

Thanks again.
[8525, TyTN, MDA Vario II, JasJam General] dmxl:
If it wouldn't be a software issue, why is it, in my case, instantly resolved when going to settings -> phone with the side buttons?
[8525, TyTN, MDA Vario II, JasJam General] rosery_82:
i had this problem i took it to a guy who fixed the problem he said it was a very small tear in the flex cable which causes this white screen every now ant then and the buton problem , sorry to say its the cable problem and u need a very capable person to fix it or replace it with a new one . its very common problem baised on the guy who fixed it .
[8525, TyTN, MDA Vario II, JasJam General] abufijli:
Exactly what is happening to me, no white screen issues, just screen taps and answering calls, I also have another problem where the PDA will not allow me to open anything, be it the start menu or contacts, it will open and quickly close again. I have had mine swapped through Telstra in Sydney, it worked fine for a while and then the same crap again. These problems started before I even touched the OS, so it must be a build problem. Maybe we should write a joint letter to HTC letting them know that there is a serious problem with their machine.
[8525, TyTN, MDA Vario II, JasJam General] thewall:
I have had the same problem, got my Tytn through work so we sent it back to the company that supplied it to us. Got it back yesterday and they had replaced the "switchboard". Not sure what it is but there was the problem. Had white screen and buttons not working.
[8525, TyTN, MDA Vario II, JasJam General] dmxl:
This is so frustrating.

Now besides the hardware buttons on the front, my sidewheel also stopped working as well at least 2 times a day. A softreset temporary solves the problem.

Also, the green and red phone buttons at the front always stay lit up when the screen is also on. I don't know if this is standard.

They already swapped my phone for a new one. This is the new one.

HTC really has quite some issues.
[8525, TyTN, MDA Vario II, JasJam General] MikeChannon:
That is standard.

Mike
[8525, TyTN, MDA Vario II, JasJam General] mattytj:
An update

Well, I recently dropped my Jasjam and the problems I've been having have reduced noticeably.

I could normally replicate the problem by placing the phone in standby, waking it, pressing the green button or center button, then trying to scroll down then up using the dpad. This would result in my not being able to scroll up, and the left, right and up dpad buttons would only rapidly scroll downwards in whatever screen happened to be open. After returning to the home screen none of the front hardware buttons would work.

Now it's more random. The problem remains but isn't as frequent, and I can't always replicate it.

So, um, hooray for throwing my very expensive PDA phone around! Maybe this will help others? ;)

In all seriousness I'm thinking this confirms a hardware issue, probably something loose that got knocked a little more into place but could quiet easily come loose again.

I'm thinking I want a replacement, I've still got 18 months or so on my warranty. Any suggestions as to how to get a replacement rather than them trying to repair it? I'd rather start from scratch.
