[Q] Actually bricked a samsung i500. Help?

So...here's the thing. Supposedly it's impossible to 100% brick an i500. Well I believe I managed it. If not, I would REALLY like to fix it. I use it just for media stuff these days, like reading and music. So...here's what I did. I know it was stupid.
1. Rooted my Samsung Fascinate i500 from Ntelos.
2. Got a bunch of replacement apps, like Go Launcher EX, and pretty much every other thing the GO team came up with.
3. Used Titanium Backup to delete system apps(like the launcher, basic internet, and some other stuff) instead of freezing them. I am an uber noob. It shows, yes?
This was all some time ago, when it was actually connected to a plan and used as a phone. It still worked...most of the time. It would derp and freeze up occasionally, but otherwise worked fine.
4. At some point a few days ago I somehow uninstalled something that caused the wifi to cycle itself back on no matter what I did (including turning on airplane mode, it just turned airplane mode off and cycled the wifi back on) causing battery drain, since it's constantly searching for SVC. So since I couldn't figure out what happened to cause this, I decided it was time to finally get a custom ROM. I used ROM Manager to try and flash a custom rom I cooked in this online kitcheny thing.
It didn't work. Anyway, I went into the recovery and cleared the cache thingies, hoping it would help.
Instead, I no longer have a launcher. Since the default launcher was gone, apparently it won't let me use my Go Launcher EX anymore, or even bring up the menu to set it as a default.
I went through the steps to flash a new ROM or the original I found using ODIN3 and the download screen. I can get to the download screen fine...but ODIN3 won't recognize my phone. At all. Ever. I do have the right drivers, if I'm not mistaken.
Well...at this point, I don't know what the hell to do. I don't have the money for a new one, or I'd get it and start over and do it right this time.
Halp?

This problem is solved.
So...yeah. I forgot I had to use the original cable. My bad. I fixed it. Hooray!

Have you tried accesing the recovery or download mode, by pressing the top/bottom volume? If so, you should be able to just flash a new fimware onto it.

I too am experiencing this with my N8000.
What you should do is when you start or power on the device, Just leave it sit frozen with the writing you too.
Eventually, the device does boot, its like has a corrupt partition, or some type of corrupt memory or drive, or at least thats what I suspect.
Still experimenting and equally frustrated by this.
I also bought a used fully functional N8020 4G version to see if I could replicate or assist trouble shooting.
My efforts show that both S Pens works on the N8020 fine, and both S Pens do not work on the N8000 which has the boot issue too.
Tell me, does your S Pen work fine if and when you get your device booted?
Its really weird but if I dont get it sorted soon, I might just keep the N8020 and ebay off my N8000 which is a shame as both are cool, but I only need one & especially one that works.
Would be keen to hear from other users with similar issues or fixes.
ps:
I have tried a couple of stock roms, and issues (slow boot appears frozen and no S Pen functionality) are the same.
When in recovery, caches cleared and full factory date wipe data and install.
Other symptoms.
After doing the total wipe and reboot, the device still takes it time booting to do the install.
With and without charger inserted, its still the same.
Another point, when you turn off the device, the battery icon appears, it hangs on the battery picture with a little circle on it.
After about 2 minutes, the full battery colour progress icon shows and shows the charge happening.
Hence, suspicions towards potentially corrupt memory or drive, plus maybe cracked circuit board even? I rule nothing out here.
There you have it, appreciate feedback or other recommendations.

after installing a stock rom the tablet starts in bootloop then I discovered that letting the battery becomes exhausted, re-starting recovery screen appeared, I pressed on wipe memory rekindled and tablet restarted without encountering any difficulties.
The s-pen did not work because the csc was unknown, after flashing the right csc the spen has started to work well.
Anyway attentive to the stock rom you have installed I Have flashed a (4 files) from a site very close to samsung and it was fine, another downloaded from another site (1 file) not good.
Excuse for my bad english and I hope to help you

Hi Sirduffy,
Hey, thanks mate.
I only just finished doing some testing and made some progress myself.
It seems that it was one ROM that I seemed to get bogged down on.
Here is what happened for me.
I was using
Australia 2013 February 4.1.2 N8000XXCMB1 N8000XSACMB1
http://www.hotfile.com/dl/197957288/5d7de66/N8000XXCMB1_N8000XSACMB1_XSA.zip.html (GAVE SLOW STARTUP + FREEZING)
I then just installed this, and then did a cache wipe and full wipe reset. Now it boots perfectly every time.
Australia 2013 March 4.1.2 N8000XXCMC4 N8000XSACMB1

Excellent, this is likely exactly the info I am looking for.
Can you tell me, is it possible to update only a CSC file with Odin 3.07 flash??
Or do I need to redo the whole ROM above and also include a individual added CSC file?
If so, where do or can we access these files or choices of files to match my Rom, or country, N8000 model etc etc.
Or where or how did you get your one?

You out there still SirDuffy?
Can you please elaborate a bit more on where to get such csc for the S Pen to work.
My Rom as mentioned boots up fine and shuts down and does everything perfectly except S Pen which does not work.
Or at least when I pull the pen out of the tablet the Shortcut sidebar pops out confirming the pen is in use.
Would really appreciate more info or instruction if you can help.
I read on a few other threads about how to change CSC but I do not know where to get or what I am meant to be changing as yet.
Plus I am wondering why this would even be the issue when the CSC (Consumer Software Customization) denotes to a specific geographical region or carrier. The CSC code contains the info about software packages specific to a particular region, carrier branding and also APN (Access Point Name) settings for data connection. (as written from droid views).
So a little lost in the S Pen department.
Any body else out there got any suggestions to why my S Pen does not work?
I have done some tests as mentioned above previously and any suggestions would be great.

Hi again folks,
Just replying to myself to advise others who may also have similar experiences as this, that I have now fixed my issue with S Pen.
I went back to ICS Stock Samsung 4.0.1 XSA, done a cache clean, then full data/wipe to finish install.
(with the SPen always inserted).
I then updated to JB Stock Samsung 4.1.2 via Kies, which also shows that the Pen is still working.
This is a very weird problem when it happens, how it happens, or why is not exactly known.
But my guess would be a partial corruption at some stage, some where through a process or a combination event that corrupts something obviously.
Anyway, persistence wins the race in the long run.
I have never rooted my device and always installed Stock Sammy Roms which for this model for me there are only 2 (but a 3rd using a different country as I did also use a German JB Rom to also try a CSC change, which also needs to have a cache reset and Data/Wipe type install too. And then when moving back to the Rom of your country of requirements, also do these cache cleans and full Wipes each step of the way which also enables the correct CSC as shown in Recovery Mode.
Eventually its like the device just gives in and surrenders back to S Pen Functionality.
The last thing I am going to say is that my device was or is still under warranty through Kogan.
I told them via email that I had been trying a few ideas from reading this site and they then in some way accused me of flashing with a custom rom which I have not.
---edited---
To this day, my N8000 has had NO Custom Roms on it, and I am totally Sickened by the fact of their reply which still shocks me.
But then, hence my reply.
All the best out there to those with S Pen issues or Bootup Freezing, as XSA through time will help you be persistent and move forward with or without warranty providing you have the patience to succeed.
Cheers~!

I have sent you a private messagge

Guess you'll wait forever.
What a sick advice that was.
Read about flashing with odin in download mode + go to sammobile web page and download a for your device - it's a BASIC knowledge, you must know.
Bootloop does not mean that the internal drive is corrupted; it is the least possible issue which may happen.
Bootloop means that the system files are messed up or kernel is wrong or blah blah blah
Don't think too much about CSC... just flash the full firmware with odin and your device will be working again. Btw, firmwares are described with CSC names: i.e. XEO for Poland, EUR for Greece, etc. Choose one your CSC - or any other you wish (it will work without issues; you will have your language version; some not essential added content may differ only...).
And if after that your device will still refuse to recognize s-pen then it's a good point to admit that it's a hardware issue.
You may want to regulate spen potentiometers hidden under the button, with a knife. But that's the other story.

[Q] Note pro 12.2 keeps rebooting after using facebook app

i just got my note pro 12.2 wifi version (international) a few days ago and already experiencing problems, firstly the wifi was so slow so i updated it OTA to the latest stock firmware i can't remember what it is but it's the latest official 4.4.2 they have and that improved the wifi but now i'm encountering issues of rebooting randomly after using facebook app. it's always after i lock the screen it suddenly reboots after 2 mins or something especially if i have say been using a lot of memory for it.. ie if i scroll down 4000 friends that's when it always reboots once i lock the screen. is this liekly to be hardware or software issue or an app issue?
i have only had it a few days so haven't managed to play with it enough to test it to the max.
just now it rebooted and i played one youtube HD video and used multi window to use the facebook app (old version 7.0 - i like this version).. but i hadn't used the facebook app that much while on, the only thing i did different was i plugged in my samsung s3 charger into the note pro to test how long it would take to charge using a usb 2.0 connection instead. it's official charger official cable, is that likely to cause reboot issues?
previously it was just after using facebook for a long time for a ram intensive amount, i also tested it after reboot and using facebook a bit and locking screen and it didn't reboot so it made me think ok it's just when facebook is being used a lot and all the ram and memory is exhausted caching 4000 friends viewing so i didn't think anything of it.
is this likely to be hardware or software issue? are hardware issues ever the main problem with rebooting?
I know the usual tests, having to use odin to flash official firmware, trying a different facebook version, removing and not using facebook at all and see if it still reboots and lastly factory reset.
ideally i'd like to avoid all of those things as it is a major hassle and i can live with the reboot issue provided it isn't a hardware problem. is there anyway to test it to know for certain it is hardware and not software and the app?
edit: it keeps rebooting even if i dont use the app
seems to happen when i lock the screen sometimes it just reboots randomly.
anyone else have this?

You could try to remove that facebook app and see if that fixes the problem.

does anyone know what is causing this?? is it hardware?
i've factory reset removed all apps, then added one app at a time then added about 6gb of videos and added wakelock detector. all seemed fine
then i tried to unmount the sd card and then it rebooted.. why is it doing this??

Could it be a bad sector on the SD card? I'd long format it using a pc to be sure.

it's not the faceboook k app i've realised now it just coincidentally seemed to be that as it is ram intensive.
i factory reseted and then put the app back on but didn't log in. 3 times it has rebooted by itself over different scenarios.. 1 plugging in a samsung usb 2.0 charger from a samsung s3, 2 when unmounting sd card, 3 when closing the screen when any ram intensive app is in the background (there's still like 500mb of ram left!! i dont know why it's rebooting like this.
i can't figure it out. is anyone else having these issues? im not sure if it's a kitkat 4.4.2 issue.. reading forums from other users with different devices i'm seeing the reboot issue coming up alot especially on the s4.
http://forum.xda-developers.com/xposed/modules/samsung-kitkat-systemserver-crash-fix-t2806046/page22
but i dont know for certain if it's a hardware issue.
my next steps which i really want to avoid is to factory reset AGAIN and not load any apps (the problem with this is it requires a certain amount of ram intensity to be used before it randomly happens.. if i dont add any apps like instagram or facebook or tumblr i can't get it back to the state where it reboots randomly)
i've also enabled all apps (i usually disable all the bloatware i can without being rooted) but it does bring up errors of android.core.process has stopped etc and some gapps errors (im hoping this is the cause of the reboot) and see if it reboots. it's difficult recreating the scenario consistently.
i udnerstand it might reboot if you've overused the memory but it clearly shows lots is free so i can't figure out what is causing it?
my next step after all this is to flash the latest version of stock so i can't put it down to the OTA updates that is causing it. if that fails i revert to odin to flash the original 4.4.2 it came with.. and failing that i'll have to return it
does anyone have any ideas whether it is hardware (maybe the power button is slightly off so when you press down it in a certain angle it triggers a restart?)
or is the motherboard or corrupted sector of the memory which when it writes over it causes the reboot?
i always assumed reboot issues were normally always firmware issues and not hardware.. surely samsungs quality control is a bit better than that??

If it were me I would yank the microsd card out, factory reset, set up just my gmail without allowing auto backup/restore and apply all updates. I'd then let the tablet run for a full day and use it just for web browsing and Youtube to see if the problem is still there. I would not install anything for at least a day, including the microsd card. This would be as stock as one could get and rule out the possibility of it being any software that I installed or the microsd that I was using.
I suspect it's software but the only way to know is to be patient and test it out for sure.

Hi,
same tablet, bought there is 3 weeks. I installed the latest firmware update (XXUANI1)
I rooted the tablet (to allow sd-card writing).
and that's it.
like some of you, I have random reboot.
I can't remember if it happened before the root or not. I think that yes, but I am not 100% sure.
I don't see anyone reported that the root cause random reboot...
it is really random. sometime, the tablet stay one night without reboot, sometime, I can have 3 reboot in one hour.
I don't find what kind of application is causing that issue.
I really believe that it is software. before the firmware update, I stayed 2 weeks without any issue.
I tried to reboot in recovery mode, and wipe the cache, without success.
I will probably try to do a factory reset...

Assuming you have custom recovery installed as well; have you tried wiping dalvic? It will force applications to recompile and possibly fix a corrupted application or its associated files.

Hi,
I just checke.…
I was thinking that the root method was not setting the knox flag, so i was thinking there is no recovery in the file flashed… .
I was wrong.
My waranty is void, knox is set. I still have no custom recovery : in the file provided by chainfire, there is a recovery which is probably coming from samsunG…
So i will install a new recovery and try to wipe all caches dalvik.etc.

Hi,
since my knox is set now :
I tried to install TWRP recovery, which allow me to do a wipe of the cache AND dalvik Cache.
it did not resolved anything. the tablet still reboots randomly.
then, I decided to restart from scratch :
I flashed the same firmware I had, using ODIN, and do not root it.
this is this firmware : http://www.sammobile.com/firmwares/database/SM-P900/XEF/
I will keep you updated if it solve the reboot issue or not.
thanks

Hi
I had the same problem and also thought it was the power button that was faulty but then I flashed the previous firmware then tried to use it a bit and no reboots since so I guess samsung released a new firmware that solved the slow wifi problem but then boosted it a little too much or so it seems judging by the reboots whenever there's too much overload.
So I guess for now I will stick with an older firmware

oops... it rebooted while I was surfing the play store so I guess I spoke too soon

[q] Phone is constantly getting problems

A while a go I have bought my girlfriend a Jiayu G4 for her birthday but it has constantly problems like freezing while using, not responding in sleep mode (both are only solvable by getting the battery out and restart it that way), deleting things off the SD card, apps not working correctly etc.
I have tried 5-6 different roms from Needrom and the problems didn't go away but with every rom I experience other troubles with the phone. So it depends on te rom which of the named problems occur. I have also tried 3 different SD cars with no succes and I'm about to give up on the phone.
I wanted to know if you guys have things I could ccheck or the sollution for me.
Thanks!

For the purpose of troubleshooting, I would root the device and install Logcat Xtreme and Bootlog Uptime. Run them once to set then up first. You can always un-root after troubleshooting if desired.
If you can re-create the freezing, use Logcat Xtreme to capture the log of the failure snd submit it in the ROM thread for your device.
Boot log uptime will allow you to export the kernel last_kmsg, Also for submitting in the ROM thread for your device.
Investigate whether the system and data partitions are full or close to it as well. That can cause all kinds of issues.

Looking to Undo Root and All Customization, Need Help to do So

Ok, so as the title says, I'm looking to completely undo having rooted my tablet, and all the customization I did to it, but I'm having a bit of trouble.
According to multiple apps my tablet is no longer rooted, and I got the stock rom from Sammobile flashed on it, and I have the stock recovery back, but I seem to be suffering from the wifi problem that CM suffers, I know this as I can connect to my 5G wifi as well, which I'm never able to do when the tablets wifi is working correctly, and also even connected I barely have any speed, if even any.
Now I know of the wifi fix you can flash through TWRP, but as I said, no more TWRP, and I don't want to reinstall it, I want everything back to stock.
Now, I know of Wifi Fix's for other tablets, like the Galaxy S4, that you can flash on with Odin, but I can't seem to find one like that for the Note Pro 12.2. So if anyone can send me a link I'd really appreciate it.
And also, I can't remember, but did the Note Pro 12.2 ever get anything higher then Android 5.0.2? Because I try to update it, and it says because my tablet was modified I can't do so. Plus Sammobile doesn't have higher then 5.0.2 but I read somewhere that it got 5.1.1 so I really don't know, any help on that front as well would be great.
Now, you may be wondering why I want to do this, in truth I'd rather have my tablet rooted, I save so much battery life getting rid of all the bloatware. But no matter what I do, there always ends up being a problem with my tablet.
I follow all the instructions given, I do exactly what everyone else does, even having someone walk me through it step by step once, and always it goes horribly wrong.
The first time my Nova Launcher would crash constantly, and then everything else would start crashing with it. Then the second time all my videos would play stuttering and jerky, and the audio would be out of sync horribly, and nothing I did would fix it. And now most recently, even though the tablet it connected to the computer, the drivers always fail installation, and even when they are successful, I'm still unable to actually access the tablet from my pc.
I read somewhere that it may be because I disabled Media Storage, but with Media Storage I have just as many problems, it drains my battery like crazy, it causes things to load up extremely slow when accessed through the computer, if a folder has a hundred files for example, it will take almost twenty minutes for them all to load up, and you can't do anything until they do, and if you try copying something into a folder without going into it you'll just be stuck in an endless loop of copying that never ends.
But without Media Storage everything loads up just as quickly as say an SD Card, so said 100 files only takes a few seconds.
And worse thing it caused, which troubled me for a long time before I found out what caused it, at random the media storage would decide to claim 20gb's of space, saying it was all taken up, when it isn't. And it would keep happening at random times, and at random sizes. Near the end it had taken up every bit of free space I had and didn't change back even after several days which is what led me to looking up what was causing that in the first place.
So as you can see, leaving Media Storage enabled is a big no for me. So as such I'm unable to root and customize my tablet for that reason as well.
Now, before you say how weird it is that I have such trouble, and how you have no idea why it would happen, there is a very key reason, Technology HATES me. Trust me, more often then not when I try to do something that works for literally everyone else it fails for me, like say connecting an Xbox controller and getting it to work on my pc. Yeah, never works even after almost 5 hours of trying. So yeah, technology hates, maybe even dispises me.
So anyway, if you can help me fix the wifi, and the update problem if that's possible, I'd really appreciate it.

Are you able to get it connected to a PC?
There are tutorials on how to go back to complete stock if you haven't tried Knox I might search for what people have done before they take the their device back to the carrier. Many people want to un-root before they give up their old devices.
