[Q] Would this be a hardware problem? T210R hangs, reboots - Galaxy Tab 3 Q&A, Help & Troubleshooting

On my stock T210R I experienced the system freeze and reboot just a few seconds after power up, it was all stock.
I installed TWRP 2.7.1.0, then wiped it off. Installed gr8nole's ROM (Nov '13 deodexed, rooted). After doing so, there was a Kernel Panic on boot, so I installed Blackhawk kernel 2.1.
After doing all of the above, it still boots up, comes to the initial setup page, runs a few seconds, freezes and reboots.
Do you think this is a hardware problem?
Any suggestions before I sell it for parts on ebay?
Thanks in advance

logs?

does it stay long enough to get logs? even if you have to boot a few times to get them onto your pc and check them out from there?
also with twrp there's some unexplained issue of /data getting corrupted on flashes, the only remedy for which seems to be using the format data option.

Sometimes it goes for several minutes before it freezes, especially if the battery is full, even then apps just randomly close without a notification... Maybe storage related?
Care to share how to gather logs?
Thanks

I would use ODIN or KYES to flash it back to OEM stock firmware. Also remove the micro SD card if you have one in there, sometimes corrupt cards can cause boot loop.

fyi- you can get a lot of different info from files that have info to give with
cat /directory/file > /sdcard/output.file
mostly from /proc and digging through /sys
when you get something crazy looking that goes on forever press ctrl then c to stop.

The tablet did the same without the sdcard, and I tried a couple times to do a factory reset with no luck.
The fact that it does the same with a different ROM and kernel is what makes me think it's hardware related

Cool, i'll get syslog installed and see if I can find anything.

Weird thing... It's been up for a day now, I have catlog running and recording; the only different thing is that I enabled battery saving mode, and batt is 94%; I have not used any apps other than checking battery and running catlog, but I did not have to use it for it to freeze and reboot...
If it is still running by this evening, I'll enable one thing at a time (GPS, sound, etc...)
Thanks @moonbutt74 and @dsilx

awesome

Awesome to hear sounds like @moonbutt74 was right
Hope it keeps working have fun

Ok, it seems to be hardware, as soon as I disable Power Saving mode, the tablet freezes and reboots.
As I understand, power saving mode limits the CPU to a lower performance tier; so I think the CPU is having troubles.
Oh well, as long as I don't try to mine bitcoins with the tablet, I should be good to go.

I'm running rooted deodexed stock ROM with Blackhawk 2.1 kernel.
But as I mentioned in the OP, the problem was there with the full stock device, the new ROM and kernel were installed after the problem started.

ouch
i think you pegged it right with internal storage being damaged.
only thing i can think of besides getting your money back is do a full data partition wipe and format
and a full system wipe and format
either way that has to suck. sorry i couldn't help.

Constant Reboots!! PLEASE HELP!!!!

Hi guys,
I am using a Sony Ericsson Xperia Arc and am having a lot of trouble with the device constantly crashing and rebooting.
when this first happened these are the steps i took.
i completely wiped the device (factory reset, wipe dalvik cache, wipe cache partition, format system)
i then flashed Baseband 77 using flashtool
i then flashed fxp149 using flashtool
i then flashed Baseband 77 libs using CWM
i then flashed AOKP JB M1-R1 ROM using CWM
i then flashed gapps using CWM
i the reloaded all apps from the market and not applied any backups and yet it still rebooted all the time.
Since then i have tried using
Fusion 3.8
Fusion 3.9
Fusion 4.0
FXP 148
FXP 150
Stock Kernel inside ROM .zip file.
I have also tried putting it back to Baseband 72 but it made no difference.
None of these make any difference to my issue and yet before i had the issue, I had used all of these kernels except FXP 150 and they all worked fine with no issues at all.
I then decided to go all the way back to stock firmware as it is out of the box.
so I used flashtool and flashed LT18i_4.1.B.0.587_(1254-2716).ftf
I reloaded my applications and monitored the device only to see that by the next day, the problem had returned.
I am now at the end of my tether and do not know what else i can possibly do to figure out the issue.
the device has not been dropped or damaged in any way so there is no reason for a hardware fault.
i desperately NEED this device to be working as i use it on a daily basis for my business and cannot live with out it.
IF THERE IS ANYONE OUT THERE THAT COULD PLEASE PLEASE PLEASE HELP I WOULD BE FOREVER IN YOUR DEBT!!!!!!!
i also have a logcat that i was running in the background when one of the reboots happened
not sure if that can tell anyone anything but i have it if it does
First flash stock kernel (587), after flash the rom compatible with kernel. Remember full wipe before
have you tried not to restore your apps? Maybe one of them causes the problem. I'd try to stick with the clean (stock) rom an check if it still reboots. If it does I guess your device is ready for ebay
Could be a loose battery, try a bit of paper between the battery and the cover and see if that helps.

will i have an issue with getting it repaired since i have unlocked my bootloader, flashed different kernels and roms and rooted the device?
if so, is there any way i can get it back to official "out of the box" state?

i have come across something quite interesting.
i had someone look at the logcat i had running live when i had a reboot and it showed that the last thing to function before the reboot was wifi scanning. they suggested i try turning off wifi and running the live logcat again to see if any reboots occured.
it has now been just over 48 hours and i have not had a reboot at all. i know is because my terminal session is still running the live logcat.
is there anyone that could suggest why this may be happening?
i mean, i know its wifi that is causing the problem, but would that be a hardware issue that could be fixed under warranty? or something else?
any suggestions are appreciated as always

i don't think i can help, i just wanna say that i had (have) the same problem. I said had/have because probably I still have the issue, but i don't notice it that often. Before, I had my phone set to ask for pin code, but now I have removed it to avoid being unreachable if a restart occurs. I have raised the issue long time ago, but really didn't find any answer. Other ppl had same problem with their phone (look at the thread i started about this issue http://forum.xda-developers.com/showthread.php?t=1765537)
I also have HTC desire in daily use with CM7.2, that also reboots quite often. So I don't think the phones are broken. More likely it's kenel or rom or app issue, or some combination of those.
If you can tell me how to monitor things, I can do it on both phones, maybe we will figure out what's going on.

if you open a terminal session and type:
su
cd sdcard
logcat >> logcat.txt
it will create a .txt file and put the live logcat info into it.
you need to leave the terminal running in the background to make sure it continues to update
then when you see a reboot just get the logcat.txt file from the sd card and open it in wordpad or something. (notepad doesnt display properly)
have a look at the last thing that happened before the reboot and see what it tells you
mine had info about wifi scanning and showed that it had seen ssids
next step was to turn wifi off to see if the problem stayed or resolved.
good luck!! id love to hear how it goes

Anyone have this issue?

So last night, I guess my phone was trying to download and install security update from samsung and failed. My battery died later cause it was low and after I recharged my phone and turned it on, my phone literally took a crap. Everything crashes even settings. Cant send a text out. Bluetooth wont turn on etc.
Now after I back up my photos somehow, what would be the best way to restore to keep root and CWM?
Settings-restore?
dl note 3 os then flash with CWM?
Thanks guys.
Hmmmm

It's possible during your update critical files were missed do to power loss and were replaced on reboot? I unfortunately was not able to get passed the bootscreen to recovery or the system itself. So i was forced to divert back to stock firmware and start from the beggining. So if you run into any more issues you might start there. If you kept root all should be well i believe. :good:

Don't needed. You can root the normal cf-auto-root with latest sock without problem.
After we pm chat last days about rollback to T900UEUAND4 as unique possibility for rooting, i decided to do a last try before that, and luckily works perfect:
-just did a factory reset to restore from B3 recovery i been trying to prev installed T900UEUANI1 stock, wipe caché with stock recovery, odined cf-auto-root and voilá, just rooted!
No need to do the old B3-rollback-prior-D4 method now. Just a normal auto-root with no hassling.
temp maybe?

When putting the tablet into sleep mode, it will automatically shut itself down. When I try to turn it back on, the tablet will only do so after I plugged in the charger. The battery itself is fully charged.
I've updated to the latest available firmware version that's available to me. I couldn't find any list of known issues, so I'm wondering if this is a common problem and if I should return my tablet?

Same here. It seems that the problem maybe is temperature: after some time charging it gets really hot and maybe can't awake from that and need rebooting.
I've disabled the magnet sensor vía 3rd app to off the close-lid functionality but don't improve the problem.
Here in summer the room gets to +30°c and the Tab ups to almost 65°c when it gets hot!
Maybe it just reach the temp threshold and self shutdown, or intend that not letting awake.
Perhaps CM11 build here charges battery too fast, with higher voltage than allowed and provoque overheating. I mean, i really feels that it's charging real fast..
Well currently its winter and cold. My tab was cool but it does not respond after deep sleep unless i reboot. Dev said he will look into it and i will wait. Not sure if temp is cause as mine was not definitely not hot.

Posted update last night, check it out
Thanks, btw, i was able to use ODIN to get a good version of TWRP and the ROM installed smoothly. I have encountered a few small bugs but nothing to report that is new. I noticed the "sleep of death" I think you are referring to, deep sleep resulting in a manual reboot to wake up. I have noticed my bluetooth disconnects and reconnects every few minutes during deep sleep..not sure why. will report back. Thanks SO SO much for the development, i love it, so sick of the green and blue and the settings tabs on this stock OS disgust me. I am curious tho, am I the only one who noticed significant slowdown and lag compared to stock? I do not put a lot of stock in benchmarks (skewed toward uncle sammy) but they also showed big slowdown....just my very humble and grateful early experiences. Thanks again.

Well there's a problem right now, seems that this rom prevent to enter recovery.., this is what happen to me:
Reboot from Android with 'reboot to recovery' option and when the TWRP splash logo shows it enter in a bootloop always to this instance that TWRP logo appears.
Then i just installed the good old UAND4 rom and it works fine.
Maybe i shouldn't go to recovery direct from android to prevent bootloop happen and try to go the normal way from boot.
Don't know, maybe I'll try some day.., or maybe better wait to Android L comes to us.
Please advice all that stuff in the respective threads, i can't.., cause' these 'noobs-wait-to-10-posting-before' rules..

1. You can "dirty"-flash (install w/o wiping) the new ROM over the old one - nothing to re-install - if you wish you could extract the kernel (boot.img) and flash it by Flashify
2. There haven't been reported any SOD issues after flashing chhaggerty's latest ROM version
3. I have had no issues with with TWRP after having flashed the KOT49H.T900UEUANI1 - I just assume that some parts of the Firmware, not touched by cm, has been improved (but since this is WIFI only, it might not be the case for a non phone device) why I preferred to make the update.

The changes done between the two versions (99% sure) was only some modifications in the kernel-code. Why flashing the kernel only should be fine, it will resolve the SOD and also make it run cooler. But if you wish you can also dirty-flash. However, cover your bases with a full back-up.
No issues at all with the reboot to recovery option

HERE it is
unzip the downloaded file
place boot.img on your SD
use Flashify to flash the kernel
after this I believe flashify will boot you up in recovery, just reboot and you should be good to go.
Just remember to make a back-up for just in case...

Installed boot.img and works flawlessly. Now i can back using lid cover again and no more hangs.
I hope they can solve the auto-rotate thing next time.

I have twrp 2.8, v2 of our Cyanogenmod, set processor to on demand as suggested...
Still when I play games like CoC and others, if I am not plugged in even with a lot of bat% left, I get a flashing screen and occasionally my tab just decides it needs to shut off.
Any thoughts on what to do? I have greenify and Xposed installed too...
It pretty frustrating.

My guess is that gaming need more power, why I would stop greeify and reset the governor to interactive while gaming. But other than that I have no ideas, as I haven't heard of this problem before.
This ROM is fantastic! Smooth, fast, responsive and just as described...big thanks.

Still when I play games like CoC and others, if I am not plugged in even with a lot of bat% left, I get a flashing screen and occasionally my tab just decides it needs to shut off.
Any thoughts on what to do? I have greenify and Xposed installed too...
It pretty frustrating.
THANKS GUYS!!

I don't know if you noticed, but chhaggerty just released a version 3, maybe this will work as there has been some work on the governors.

Can i use the 4.4.4 GAPPS instead of 4.4.3 you are posting?

Thanks for another quality update, notably when reading how other cm11 exynos versions always seems to break something. With your T-900 cm11, I have never had any issues. The latest version is still running smooth, the changes in the CPU governor will probably allow for better battery life with the added conservative setting. However, I don't know what trade-off this will have on performance.

Maybe they start to use the big.LITTLE behavior of the Exynos, instead of ever using just the full power a15 cluster (battery eater).
I've haven't tried it but since it's a 4.4.4 rom they should work fine.
Error flashing ROM
Hi guys,
I get this error message when I try to flash CM11:
"Can't install this package on top of incompatible data. Please try another package or run a factory reset"
This is a brand new rooted SMT-900 Tab Pro 12.2". Here's some notes:
- I received the error using V1, V2, and V3, all receive the error message
- I downloaded two copies of v3 from two separate mirrors (CA and AZ), both receive the error message
- I did a factory reset and still received the error message
- Wiped davlik/cache/system partitions
- Tried on TWRP 2.7 and 2.8, both receive same error message
- All I have done to this tablet is root it, install TWRP, and create one backup
Any thoughts? I can try using CWM if someone can give me a quick overview of how to install it and remove TWRP (or keep TWRP).

Phone shuts down abnormally.

Guys I don't know if there's something wrong with my phone or not. Whichever rom or kernel I try, there is an abnormal shut down of my device. Like I'm using it and I leave it for a few minutes or so and it shuts down. I'm not sure if it had something to do with deep sleep or anything, but I need help. Please guys anyone
on custom kernel, random reboots may happend when
1. trying disconnecting whatsapp call
2. trying disconnecting gsm call
can you plug in audio jack to earphone and notice the device? (a strange excersize but worth trying)

Yes, When audio jack is plugged in I did notice a reboot, however, noticed a reboot without it being plugged as well.
Nothing with calls.
I just let my phone sit for a while and it shuts down. I have to power it up again. When I'm using it continuously it doesn't do that. That is why I'm skeptical if it is related to deep sleep somehow.

lets step back for a moment
if you are on MIUI10, or Miui 9.6.x
do you experience the same with your phone? if yes then you should take it up to the dealer and have it replaced. if such doesnt happen on MIUI then its some APP conflicting with your rom or kernel. try to list / think all such apps which may have given root access indefinately.
whatsapp on custom rom makes device act funny ( I experienced it many time) so does few repost apps (instagram)

Actually I'm not using miui since I unlocked my BL and it had been months since I've been using custom non miui roms. This just started recently. I get what you're hinting at, but I don't think there's something wrong w the hardware but I can't be too sure.
Anyway, yes about the apps, it did occur to me that this might be the case. So I simple wiped my device internal(don't use sd card) and wiped all system, data and everything to install a new custom rom. After setting it up, I left it for a few moments and it shut down again (had not yet installed any of my personal apps, just the regular gapps

Has been an entire day since it happened again, I've turned on 'Always on display' to just keep a lil activity on device so that it does not shut off, maybe that did it. I'll try one entire day without always on display

Thanks for all your effort, the problem seems to have resolved on its own. I'm not sure what it was.
now it's happening to me but it's much more severe. First it started slowly now it's so frequent that the phone might shut down even on boot. This is really frustrating.
I had the same problem with my redmi note 7, flashed stock rom with MI flash tool, fixed everything for me

Galaxy S9 reboots every 1 min 48 seconds. Fine in Recovery mode

I tried factory reset, removed the memory card, no joy. It does it with battery in any charge state including fully charged. It stays on long enough to check a few things, but since it doesn't reboot while in recovery mode, it seems there is a problem in the software. Running Android 10. Any ideas?
Does it do it in safe mode?
If not it's a 3rd party app.
Stock launcher, right?
By watching running services you might see the cause list before it reboots.
Otherwise reflash it; possibly corrupted or bad firmware.
Use known good rom.

Yes, it does it in safe mode as well.
Yes, everything is stock.
Sorry, I'm a noob, so I don't know how to watch the running services.
I will try a reflash. Any suggestions on where to find a good rom? Does it have to be a samsung rom?
Thanks!!

Try clearing the system cache.
Doesn't have to be the stock rom but it would make troubleshooting easier probably.
A Samsung Experience Center at Best Buys can also run advanced diagnostics on it and reflash it.

Running services shows that the settings app is using 160M of ram on average out of about 1.5G. Everything else is much lower.. i think bc the phone is working on updates after factory reset.. It stays around that level and then the phone freezes before rebooting. It is always 1min 48 seconds.
I would love to try replacing the stock rom. Is that available from Samsung perhaps? If all else fails I will check with best buy...good to know! Thanks again.

Disable updates. Try disabling the internet at start up... see if that helps.

Tried disabling internet at startup so no updates and same issue. Then tried just leaving it at the let's get started screen and still reboots. I'm guessing reflashing is next. I found instructions on youtube, do you suggest using Odin3? Also do you know of a safe place to download the stock rom? If not I guess another rom will suffice.

I never had to reflash any of my phones. I'm far from the ideal mentor for how to do a reflash, lol nothing bricked yet.
If you look around on XDA you can find links. Get the exact stock rom needed for that device.
You can use a custom rom but it may end up being a Pandora's box of trouble. I run stock for a number of reasons.
Using the same rom be preferably first to ensure it was a corrupted rom.
Normally they don't become corrupted. Using a different rom introduces more variables. It could be a mobo failure in which case a custom rom might give you a work around for it or not depending what failed. It be nice to know the hardware is good from a troubleshooting prospective... and save you needless hair pulling.
A Samsung Experience Center at Best Buy might be a better option as they can reflash it to the original stock rom.
Hey, just thought I'd let you know that I found the stock rom and was able to flash it using Odin. Unfortunately, it didn't help, but something did change. Now the phone reboots every 30 seconds rather than every 1 min 48. That doesn't eliminate a firmware problem, but it also still could be hardware. Bummer. Thanks for your help and maybe I will try a non factory rom since I've got nothing to lose.

Developer options>running services, ram usage
Watch what ram memory is doing. If it dies at the same amount in use regardless of the rom version loaded, you got a bad ram chipset.
It may be a corruption of the bootloader files allocating memory, I don't know as it's beyond my knowledge base.
This sounds a lot like a memory issue though.

Good point about the rom usage with the new vs. original rom load. Unfortunately, I didn't write down the memory usage before flashing. Now it uses about 1.8G of ram on average. The screen locks up just before the reboot so I don't see any memory spikes. Settings is using about 150M and one UI about 200

Try opening some memory intensive apps and see that kills it quicker.
If you got a bad mobo better to known sooner than latter.
Good idea. I tried a few times but since the phone is fresh, there aren't many apps. I'll have to play around with it some more tomorrow. Have a good evening!

I think you're right about the memory. It works fine in recovery mode, which probably uses minimal memory. And the build I flashed is UI 2.5 whereas I think the old one was 2.0. I would imagine 2.5 is more memory intensive.

My only question if so, is could the bootloader have become corrupted and is somehow causing this rather than the hardware?
Just a guess... if it has basis in fact I don't know.
