[Q] Star N9800 unresponsive touchscreen - General Questions and Answers

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.

EDIT 15. July, 2014.

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

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

TC camara problem

Hi,
I tried to search the forum, I googled around, but I seem to be the only one with this problem:
sometimes (I can't specify it anymore, there is not routine in this problem!) when I open my camera the screen stays black, as if the camara was covered with something (which it isn't, of course!)
I already hard resetted my Crouise, problem was fixed for like 2 weeks, but today, problem turned up again.
Soft reset does not help... any ideas except throwing it at some hard wall?
Edit: Phone is really slow when this problem come up and the only way to leave camera mode is to press the red phone button or do a soft reset
Sounds quite bad, may be a hardware fault...
One hard reset temporarily solved the problem, if you did the hard reset again would it again solve the problem (for a while?). Backup all your files and give it a try.
If not then it may be a hardware problem, in that case I would recommend you send it back to HTC or O2.
If it temporarily solves the problem then it is probably a software issue - I would recommend you try flashing a new ROM, or flash the original ROM.
Just a suggestion...
I did a hard reset again today, backing up my Files via Spite Backup, but after reseting, Camera still isn't working...
Recovering the backuped files didn't help either...
F**k, I really don't want to sent the phone in, because I only have this one, and I sure it's gonna take some weeks to get a replacement...
Is there any way of reinstalling the camera...*hoping for hope*
I have exactly the same problem and i haven't find annything to fix this.
Need some help please
I've got the same problem, I have only find (for my case) some situations...
If you turn on the pda, it works.
if you wait for a while, it works again.
if you wait for some hours, it stop working...
then, if you regular turn off and on the pda, is not secure that it works.
If you soft-reset, it works.
If you keep the pda connected via usb or ac cable, it works everytime (I'm testing it now and it's from this morning that the cam works perfectly).
So I think is a only software problem, exactly I think is apmd error.
Power saving shut down cam device, and when you click camera.exe, the os is not so quickly to return on the device...
I ask to the experts (not me, obviously) if it can be a possibility...
Also can I set, only for cam device, the power saving disabled? So I can test my consideration better?
Thanks

fuze video pop up issue

been flashing roms for a while now and everything was great until recently. i have this annoying video pop up problem that i cant seem to figure out if its the phone or what. what happens is randomly the tv/video out pops up and the screen turns to landscape mode. then all sound is lost. ive flashed original stock rom but the problem still happens even running stock. i cant figure out if its the phone and i need to do a warrenty exchange or if its something else. i am hard spld and security unlocked. if anybody else has this problem or had this problem and know of a solution id greatly appreciate it. i dont think its the way i flash roms. i flash with sd card thats formatted fat 32. sim card out and hard reset after first boot.
Sounds like you are describing the TVOUTPopup feature.
Usually, the TVOUTPopup only appears when the A/V Cable (extra cable) is physically connected to the device.
At first guess, I would be inclined towards a faulty USB connector.
yes it is the tv out pop feature. whats wierd is that its the new look from a different rom build. whatever rom i run (right now stock). when the screen comes up it turns landscape and has 4 colorful icons to choose from. internet,youtube,photos,and powerpoint office. once i hit the x button or hit close then it will keep repeating and keep the screen in landscape even though i havent slid out the keyboard. after multiple times closing the app it will stop doing it for a bit but then do it again few hours later.
Since you've tried different ROMs and are seeing the same behavior, I'm inclined to think it's hardware related. Assuming you have nothing connected to the device at the moment except for the SIM, examine the USB connector very closely for signs of damage.
If all looks ok, perform a hard reset and flash the Official HTC 5.05.405.1 ROM/Radio (should eliminate possibility of garbage in ROM) to the device and confirm that the behavior still occurs. If the problem persists, that would confirm it to be hardware.
HTH,
well i flashed the new att fuze rom. so far so good. no popup yet. this happened before though when i thought i fixed the problem. but after running a new rom for about 4 days it came back. if it is a hardware issue then my fuze needs to be exchanged right? thanks for all your help.
I have same issue with my FUZE (constant "Video Out" pop-up message, often switches to landscape mode, sound is off). Have you found any solution to this?
P.S. ...

[Q] stock i9001 with broken touchpad

Hello!
A few days ago my phone got wet.
After that I can no longer use the touchscreen. Everything else works fine, including unlocking it using facial recognition.
The phone is a Samsung Galaxy S Plus (i9001), with a replaced screen (Crushed it 6 months ago..).
The phone has been dropped many times, but it always worked fine afterwards.
I've already decided i'm buying a new phone, but I still want to try to recover all my data on the phone (messages and appdata is important to me).
So my question is: Is there some way I can access my files? The wifi is off, and so is 3G. usb is set to mass storage mode, so I can't use kies.
Maybe I can upgrade the rom with something that automatically activates some form of filesharing?
Thanks in advance for any ideas.
Also: Do you think there is still hope to get the screen working? When It is unlocked I see that one of my apps is "selected" so it would seem the touchscreen is frozen - not necessarily defective.
I've read that a factory reset can help with this kind of trouble, but I don't want to do that before I have my files..

Need serious help please!

Hey!
So I have been using an android phone from 3 years now and I have been stuck in an huge problem! And I need your help in order to solve this problem. Here is the problem so basically I have a Freetel nico (Japanese brand) which is about 3 to 4 years now running on top of stock kitkat rom or in other words the same rom when I unboxed it. After few months my screen cracked on the bottom near the capacitive touch keys. After the crack the home buttom stopped working! I was all okay with that and the next day my notification panel started glitching and stopped showing any notifications which was really annoying. Now I knew that there some serious problem, so I taught of resetting the phone so I went in the setting and tried factory reset. After few minutes it didn't go to system recovery but the phone just restarted itself. I tried it once again and got the same problem, next step I had was to hard reset it by going into the recovery. When I hold the button and let go it didn't take me to the recovery this time also. So in conclusion I came to know that there was no recovery inside the phone (I did erase the phone through recover about 2 times before this incident everything went well during that time). Moving on I rooted the phone and installed SuperSU and other softwares that could install recovery mode to the phone. I got the same result this time also, I also tried installing a different rom through the stock system update app same result.... After a year of all this work I taught it would be best just giving it to the company service center but I came to know that the company had no longer selling this device and there is no service available .
After all of that tries above I still continued to solve this problem I tried ADB resetting it through pc no luck here also! So if you guys could recommend me some apps or softwares I could try in order to reset my phone please do let me know in the comments. Or you could also ask any scripts that you want to know from the phone which could solve the problem I can do that also!
Thank you

P3100 16GB - bricked or emmc bug? what to do next?

Greetings xda-developers,
I own a galaxy tab 2 P3100 16GB model since march 2013 (pretty old yeah, but i like it, its my first tab ) It is running everything stock (recovery plus OS, JB 4.1.2).
It was working all good and serving good for my browsing, whatsapp, mails, youtube, hotstar etc etc. (heavy user of tab) Suddenly on one fine Sunday morning it restarted by itself. I thought this to be normal but it wasn't. After every 10 to 20 seconds I could hear the starting tone. When i looked to the tab, it was pretty warm on the left side where it usually does when used heavily, but it was acting strange.
The tab was restarting by itself! The home screen appears, i could start an app and suddenly it restarts and this continues every 20 seconds until the battery goes low.
I thought two new installed apps would e problem so i removed them and to my surprise(!), they were back again after next 'auto restart'. The 'auto restart' stuff happened back in January this year (after my nephew installed many games on it) but was solved when I did factory reset from settings menu.
But this time nothing successful. Neither factory reset from settings menu nor from recovery. I have tried using twrp and CM11 last year but returned to stock after few months.
I tried flashing twrp, cwm recoveries but after every boot it returns to stock. Even flashing OS didn't helped.
My problem is similar to these:
https://forum.xda-developers.com/showthread.php?t=2641158
and
https://forum.xda-developers.com/showthread.php?t=2627490
and
https://forum.xda-developers.com/galaxy-tab-2/help/unable-to-install-twrp-t3696545
Also the stock recovery screen shows the following at bottom:
# Manual Mode #
-- Appling Multi-CSC...
did not match sized '/system/csc/common/system/csc/default_workspace.xml'(No data available)
(I wanted to attach image to this post but could not find an option.)
From all my readings on this forum, I can conclude (?) that its an emmc issue (end of life?).
Need your help guys.
The tab is in excellent condition except this issue. Can this be solved?
I am from electronics and embedded system (microcontrollers) profession and hobbyist. I know replacing emmc or motherboard (or scrapping the tab, NO! i don't want to though i now own the Lenovo tab 4 8 plus 3GB RAM+16GB version ) is an obvious solution.
A (may be obvious) possibility came in my mind if external memory card could be used for booting and I (and many others) could bring their tab to use (instead of making it a paperweight )
I though this to be possible solution: https://forum.xda-developers.com/galaxy-tab-2/general/discussion-alternative-tab-2-emmc-bug-t3306862
but i am not able to understand the instructions and the links posted by OP are not functional.
Can this be a solution:
https://forum.xda-developers.com/showthread.php?t=1866675
OR
I am thinking of this:
I got schematics and service manual for p3100 from internet. I looked the datasheet for OMAP4430. I am thinking whether the boot sequence can be changed (or may be no need to change the sequence) and we can boot from external micro SD card
or something like
https://forum.xda-developers.com/showthread.php?t=1312391
or can https://forum.xda-developers.com/showthread.php?t=2109044 be used?
But whenever i plugged my tab in windows without battery or with battery, initially i could see new device found 'OMAP....' something but immediately after 2 or so seconds it shows device unplugged.
Any comments guys?
Thanks for reading patiently the long write up...
You can't boot from external SD because you aren't able to flash a high modified boot.img if your emmc got read only.
You'll need to replace the emmc or find someone who can flash an updated emmc firmware via isp (but the issue might come back in short time after firmware update).
Thanks for reply.
Well i have to search someone from my nearby city for such service.
Is it not possible booting from external even if the boot sequence is changed, i mean if hardware is modded to change boot sequence?
Humm but it will require the primary and secondary bootloaders then...
The pandaboard has increased by curiosity of such possibility. I think i need to study more...
