hi all.
As I mentioned in my other post I have been having some serious wifi problems. Basically if I leave the wifi off the phone seems to work fine. When I turn it on however, the phone becomes laggy and it does not work. After turning the wifi on from the settings page, it says it is scanning for networks. After 20-30 seconds a little bubble pops up and says "unable to scan for networks" it will continue to try and scan on and off but never is successful. The phone is better to start up with the wifi off because if on, the phone becomes almost unresponsive and I am assuming it is because it is trying to scan in the background.
I just rebooted into the recovery menu and wiped the cache and device, but no luck. Any other ideas as to why this is happening?
Little update:
I found a few other threads where people complained about the same problem. Their recommended fix involved removing the file "/data/wifi/bcm_supp.conf"
The full thread is here: http://androidforums.com/samsung-moment/46179-unable-scan-networks.html
I tried that and also did a factory reset but unfortunately have not been able to fix the problem. Does anyone else have any other ideas?
hi Scales11
I'm also having the same problem..
did the
1. factory reset
2. new ROMs - Darky 7.01, Cognition 2.3...
3. delete the /data/wifi/bcm_supp.conf file
and still no luck... and realised bluetooth isn't working either..
anyone?? please help?
If you have flashed other ROMs and still the same issue. I would say its a hardware issue.
my fix
Geekboy9:
I meddled it for hours and while others have found various odd reset/rom fixes, I concluded that it was a hardware issue which cannot be fixed.
I flashed it back to a stock rom and went to att. They agreed that it didnt have any water damage and gave me a number to call about getting a replacement. Since the phone was less than a year old and its failure was not due to my use, the replaced it with a refurb. All in all the refurb seems fine, even after I rooted and flashed the cognition rom. I would recommend you do the same.
So, i tried this method shown in this thread: http://forum.xda-developers.com/showthread.php?t=2512981.
Everything went well i can finally share wifi with my phone. I got a problem though, it seems replacing the framework, kind of messed the menu dialogs. For example when opening files instead of ALWAYS and ONCE, i get THE S PEN HAS BEEN DETACHED and GO TO SETTINGS. Is there a way to fix that?
TL;DR - Flashed a ROM designed for N3+ (which is supposed to be same phone) but touch screen is unresponsive now. Need help with SP MDT or editing uboot
EDIT 15. July, 2014.: I've asked a guy from www.NeedRom.com to tell me his LCM driver and touchscreen which are located in factory mode (VOL- + HOME + POWER). He gave me same driver names as mine. LCM driver is RX_5720TM_813a and touchscreen is ili2113a.
I've tried removing the digitizer from my phone (lost warranty, but **** it, i'm not sending it back to china) and when i've entered factory mode again, it said touchscreen: (null).
So it seems that digitizer is properly attached (and should be working?).
Does anybody have a clue what's going on here? I've tried flashing 15 ROMs and NONE fixed the touchscreen. It's fully unresponsive. It doesn't work even if I off/on the screen few times like it worked before.

Hello everyone, like title says I have unresponsive touchscreen on my Star N9800 phone. It's pretty much a new phone, octa core, quad core GPU, 2GB RAM, 16GB storage, etc.
What I've done is I flashed the ROM designed for Star N3+ (which is supposed to be same phone) but my touch screen is unresponsive ever since then. I've googled and read some articles on xda about SP MDT. It's a tool which can help us choose the display driver we want the phone to run with. I actually ran into a problem when i downloaded SP MDT. I can select the database etc, but when i get to scatter file it just doesn't want to load it. Either it's incorrect name or file type. I've downloaded 3 original ROMs from needrom.com and strangely the scatters seem to be different. But none is accepted by SP MDT. I need someone of knowledge who can teach me where to find uboot and how to edit it correctly. I'm not a linux/android programmer and I really don't wanna get involved into much programming. I understand basic stuff, i can find files on the system, i can edit build prop correctly, remove or edit boot_logo, boot anim etc, but this is a bit more than that. 2
Please share some knowledge with me and please don't point me to google. There's no solution there, i've googled for 3 days now. The last resort for me is to make a post here (and hopefully don't get ignored for spamming because this isn't spam).
My email is: [email protected] - you can notify me here if I don't get automatically emailed by xda.
Thanks in advance.
BUMP
Have no solution but would like to learn as well if anyone can help us...
I had the same issue but gave up and flashed another rom instead.
Flashing another ROM didn't help my problem. Well partially it did. I've flashed 2014-1-7 original N9800 ROM and the touchscreen only needs 1 or 2 off/ons till it starts working. I'm kinda fine with it because it was completely unusable. Flashing drivers with SP MDT didn't really help. I've tried flashing RX5720TM_828A (from N3+ ROMs) and LP057APK (default in N9800 ROMs) and RX5720TM_813A (2nd in N9800 ROMs), and so far my touchscreen works only with 813A LCM driver. When i turn off the phone and then hold VOL- & POWER & OFF/ON it goes to factory mode. There i clicked version and it showed that 813A is installed as LCM driver, BUT touchscreen says (null). Could it be that my digitizer is no longer connected or what? Cuz it sometimes works correctly without turning the display off/on at all.

Even if i boot into recovery, screen doesn't react to touches.

Apparently it's the calibration which ****ed up my phone. I'm now trying to figure out how to calibrate the screen through CWM.
ever find a solution?
i have a star n9800 too. suddenly i have been having all of the same issues, but here is the kicker: i never flashed anything but the stock rom that came with my phone, which was the same as kitkat version available on needrom.com. i have tried full factory resets, i have restored my original backup, none of it has fixed my phone. in factory mode, everything tests fine, but even when i launch in to TWRP, about 75% of the time, my touch doesn't work. i am wondering if one of the cables inside has come loose or something, but it is so intermittent that i find it doubtful.
hopefully you have found a solution that you can share with me.
Touch screen sometimes not react

Touchscreen - hardware failure
Hi,
I am wondering if you may have experience and be able to help me with my Star N9008 phone which has has had its touch screen stop working while I had it in storage for about 3 months.
Very well stored, no shock, no humidity. I keep it with my laptop backpack as a spare in case my everyday phone fails.
Today I powered it up to make sure battery was good (found it good at 95%) and update applications, etc. Basically, just checking it was still good to serve as a backup should I need it.
Thing is, I found the touch screen is completely unresponsive. Connected a mouse to it and verified all was working good, did up the updates, etc.. using the mouse. Reboot and boot into service mode and restore menu. Also, no touchscreen response (I use TWRP). Thus, it must be hardware failure.
From experience, would you know what would cause this, and how to resolve?
Thank you.
So, its been a while.
So, it's been a while. I still have the phone in storage and pity it doesn't work...
I haven't bothered opening up the phone if I don't know what to really try and also risk damaging it.
Also didn't bother ordering a new digitizer to replace as it's economically unviable.... the phone is now really getting behind as new tech is further evolving, so I do unfortunately see it going in the rubbish soon (along with two brand new batteries I had purchased for it just before it died).
Has anyone been successful at finding the culprit?
In my case, it was fine and very well stored... so I don't really have an explanation other than the phone possibly having a 'countdown timer' to break it... (yeah, a bit too conspiratorial, lol)
I did not find a solution yet , phone still sits in storage
I feel a bit odd admitting to this, but i am stumped - i bought a shield portable, am running through the setup and the keyboard will not appear when i need to type in my wifi password. I've tried skipping that stage, and the keyboard won't pop up for anything else either.
The system was rooted and had supersu(?) on it when i bought it, i unrooted it through that or thought i did, but no difference except supers is no longer present. I've factory reset, nothing.
Is there something in the settings that could be causing this, or anything else anyone can think of? I've even tried getting the recovery images off nvidia but the windows ones won't work, i downloaded the linux version and managed to extract that through cygwin as according to one youtube video i found that would give me what i needed, but the extracted files are nowhere to be found.
I feel very tired, and very stupid right now.
HELP?
Hey everyone.
I can't believe I did something so stupid, but you live and learn, and while this is not the end of the world, if anyone has a solution that would be great.
I've been using this nifty little program to record conference calls and I am usually pretty good at uploading them to my Dropbox but I got lazy and removed my root yesterday so I could upgrade to Lollipop on my Note 3. The unroot process went fine until I got stuck in a boot loop so of course I did a factory reset.
Keep in mind, prior to doing this upgrade, I did a backup with TWRP and I also had a backup with Titanium. Low and behold when I hit the home screen, all the recorded files were gone. I was puzzled because I thought for sure my precautionary measures would restore those audio recordings. Nope.
I attempted to reinstall the custom ROM I had prior and no dice on that either. I am guessing its gone, but I am throwing this out to the forums in the event someone has a solution. Thanks in advance.
I would try to extract the files from the backup. Just check here http://forum.xda-developers.com/showthread.php?t=1808486
No dice. Apparently TWRP and TiBu doesn't save certain files at the local level., including .wav files from the recording software. I've yet to find a backup online that works. I'd even be willing to pay. Lost my screen shots too. This is a hard pill to swallow because I honestly believed I did everything right until I realized I did it all wrong.
