Memory or memory controller broken? - Nexus 10 Q&A, Help & Troubleshooting

Hello,
I have suddenly a boot loop on my Nexus 10 with unlocked bootloader. That happend without any new ROMs or similar things during the last days.
I was one time able to get to the TWRP (this is difficult because of timing with battery capacity, access to memory, cpu temprature and/or what the hell).
For me the error messages I get when trying to mount the memory seams for me that the memory or memory controller is broken.
Anyone else had this?
Some idea how to try to fix that?
Any possibility to recover data (without a specialized company) by myself?

Strange issue

About a week or so I've been experiencing a new problem: the SD card becomes inaccessible and none of the applications installed on the SD able start (obviously). Soft resetting my HD solves the problem, but only temporarily for a few minutes. It really let me down a couple of times when I needed my SatNav app the most.
I'm using Laurentius26's v4 custom ROM. All I can think of is formatting an SD card. Any other thoughts?
Try some recovery software on your PC to get off as many files as possible then re-format. They can become corrupted over time. You might want to get another card though, as they only have a limited read/write cycle and sounds like yours could be slowly dying if it's been used a fair bit. If fairly new then if it was me I wouldn't trust it with my data and I'd buy a new one.

Apps2SD Nexus One and Battery Performance

Don'y know if anyone observed this or not:
My N1 with a2sd enabled consumes more power than without. This shouldn't come as a surprise to anyone as need to access SD requires additional power.
Anyone observed similar pattern with a2sd?
What does it have to do with app2sd?
That just points out what applications you can move to the sd-card.
You can do that without app2sd too...
Mod edit: Let's keep it friendly here, guys.
LOL I have not notice but I have notice a crazy lag to load icon stored on the sd card maybe I need a better class. I been doing ok on battery so far down clocking to 700mhz and flashing it to MIUI but I wouldn't doubt my app2sd drains battery since is probably always scanning to free cache.
Let's keep it friendly in here, guys.
Personally I haven't noticed any battery drain with the Froyo / Gingerbread Apps 2 SD / Apps 2 USB Storage. While that's a little different than the Apps 2 EXT, but I would imagine them both to not use much power at all. Both internal memory and USB storage use NAND flash memory, and it would be reasonable to assume that they use similar amounts of power.
Spx2000, you could have some issue in your particular installation. Perhaps try wiping cache and Dalvik cache and/or do a full wipe and reinstall your ROM.
I think there is a problem with App2SD that seems to have started with an update a few weeks back. In fact, until I started reading the comments here, I had no idea that it might be the cause. My Nexus One has had extremely slow performance and a slow battery constantly for the last month or so. It all started at once. It was around the same time as the 2.2.2 upgrade, but I swore it started a little earlier. Today I went and turned off the option to check downloaded apps in Apps2SD and it seems that my Nexus is back to its old form. Something must be wrong with the App2SD feature that scans downloads. It doesn't show up as the App2SD process slowing down the phone, but you see system load from processes such as init. If you have the problem, I recommend turning off the App2SD option which checks downloads to see if that eliminates the problem.
it is true that if I use the app in SDCard consume more battery?

[Q] phone storage problem

hey, i have an unrooted mt4g about a week ago i had to do a hard reset on it to fix a market problem but i was able to recover most of my apps and was going from there with little problem until a few days the "low internal storage" message started showing in my notifications. since seeing it, i have looked through my apps and realize there is no possible way they can take up that much space by themselves (though i deleted some i didnt use oping to abate the problem). right now, im trying to go phone storage to see if anything unnecessary is lurking there but im having trouble deciphering the files
im sure its not becaause of apps because before the initial reset, i had even more apps than currently without this problem. its like it materialized out of nowhere
i still have the low storage problem and im wonderiung of its due to something like an error stacking log or temp files. or maybe an app i installed did something to the phone memory. is there anyway to fix this and be certain of the problem or will another reset be necessary

My firsts issues with the Note 3

My Note 3 has uploaded all the software that was previously installed on my Note 2.
2 issues at this stage :
- time to time, the messages regarding Internal or External memory usage, saying that there was 1,30 Mb free ... But there's 22 Gb free on internal storage etn 6 Gb free in external SD card
- after un reboot, the phone went on reboot loop. I had to wipe data and user conf and install it from the start.
Since then, the phone needs to reboot 2 or 3 times before being ready to use !!!
Another small issue in Lock screen : the ink effect does not apply color changes ...
And at last, Wifi seems to be pretty weak hanging out several times ...

Did you root your phone or install any mods? Was the phone rebooting on its own before the reboot loop, or did you reset the phone and that kicked off the loop? Was there a particular app that seemed like it was causing a problem?
No my phone is not rooted.
Once reset, the phone is good. Issue appears after having installed my apps from Google Play.
I fought it was due to one of my apps but i think it's weird that just an app can force loop reboot.
And one thing fishy is the message about internal ou external storage being insufficient and still having so much storage left ...
One thing that surprised me is that the booting time is very short.
Lockscreen appears almost 10 secondes after the Samsung logo.
This is a problem with memory. Eject your external micro sd card. Save all the information then format it with your phone. Turn off auto update from google play. Then try to install one of that applications which caused reboot. Worked for me, i had the same issue...
Which app did u find to be the problem?

I had a continuous boot loop problem after installing a few apps. It freaked me out as I spent a long time getting everything looking good on the phone. I thought it was going to be a case of hard resetting.
I removed the SD card and suddenly all was OK! I had been using the card in a different phone. So I removed any system folders from the card and everything worked fine. That is until I reinstalled some other things and the problem came back. So I reformatted the card in the phone and now it all seems to be working.
I also had problems with changes not sticking on the lock screen. They too are now working after I did the above.
I do however still occasionally get a pop up dialog saying internal memory is 1.90Mb or similar small amount. Does not seem to affect anything but the fact it appears is a concern.
Hope this helps.
Thanks for your help !
I will try to format my SD Card (a Samsung one). I have to backup media content before.
I let you know if it works and if the popup dialog is still here (I had 2 popups : one for internal storage and one for external).
I hope Samsung will provide soon an update or a patch.
Even without the SD Card inserted, the phone needs at list one reboot to be ready ... So weird !
UPDATE:
I found what is responsible for the boot loops. On the SD card the hidden folder " .android_secure " I had 3 " .ASEC " files belonging to 3 apps I had installed:
Nodebeat
Argos
Maps With Me
Removing these .ASEC files stopped the loop but obviously means the aforementioned apps will no longer run! So I have fixed one problem and in order to use the apps I have to re-install them without the SD card present.
I've checked the hidden directory : no file in here.
I decided to remove the SD Card and hard reset my phone.
After hard reset and phone configuration, the phone reboots with no problem. Still the ink effect does not apply color change (stuck on "no color").
I started to install my apps (still no SD card in it) and rebooted the phone.
Loop started again ... The phone needs to reboot 1 or 2 times before being able to get to touchwiz.
I think only a patch or firmware update will fix this issue ...
Anyway thanks for you help and your time
Oh ! I found something weird but good to know !
I have put back the SD card, install all the apps ... Still loop rebooting ... But ...
I put my phone in "Plane mode" and reboot : no loop ! i've tested this twice ....
Something going on with the phone trying to reach the network ...

For the ink effect, it only applies if you choose Ripples for the effect. Not working on Watercolor.
Also, try to use S Pen when unlocking the screen

Indeed i was already using Ripples for effect but the ink is only applied when using S Pen .. Makes sense in a way !

I thought that the problem could be connected to one of my application.
So I did a Secured Mode boot (in order to only run the system apps) and the problem is still here.
So one of preloaded apps, after an update, could be the cause on my loop reboot.
You're absolutely right. I have the same issue with the Samsung logo showing up shortly after booting. Restarted the phone while in airplane mode and the issue goes away.

I'am at least reassured not to be the only one facing this reboot problem !
Just a thought

I don't know if the OP or the other poster are still having issues, but the fact that the reboot is affected by airplane mode brings the SIM cars under suspicion. I would get a new SIM provisioned by your carrier, and if the issue persists I would be getting a replacement device pronto. There is absolutely NO reason a new device, right after resetting should be anything but perfect. Accepting anything else is at your own peril. If you had attempted or performed root, or any other type of unlocking attempts I would wonder, but you state that you haven't.
The most important thing is to prove if it is the device, the cards or software. For me, AT&T would be shipping a new phone overnight just in case Theres no way I would take a chance on the presence of a defect at the price we pay for these.
Yes I confirm device is untouched (not rooted).
I don't think it's a SIM card issue as i have tried with another one. One other thing is that the phone works nicely from fresh start. It's after having updated the preinstalled apps, installed Samsung Hub and installed my apps that device goes on loop after reboot.
I think it's more a firmware thing, like the handwritting input mode not working on some device (I never have this problem but just in case i installed the OTA update provided by Samsung thru Google Play today).
Let me conclude to the post.. one of my friend bought this phone after the launch day it was a 64 GB Snapdragon 800 and the device over heated like **** and he had to return it the next day after paying 800$ upfront or more!!! I don't know what's happening to samsung..., I guess we should go for nexus 5!

But was it just because of the indexing service indexing a large SD, or even lots of files on the internal SD, or even a large dropbox account?

Help! Note 4 freezing, crashing and constantly rebooting.

Its been a long time since iv been this stumped, about a week ago my phone started acting very strangely, laggy performance, freezing randomly and occasionally rebooting itself, now its getting worse, getting to a point where the phone is probably rebooting itself 5-6 times a day, iv uninstalled every app, iv factory reset it, wiped cache, replaced battery, removed the SD card (in case of file system corruption) using Samsung Smart Switch did an emergency flash back to original Rom, installed every troubleshooting app out there, monitored RAM and CPU usage, all i can see is that the CPU suddenly spikes to 100% with no real reason, i cant link any particular app or process thats causing this, all of the cores on the processor appear to be coping with no faults.
The only thing i can think of thats causing this issue is either iv got a pending hardware failure on the board, or possibly bad blocks on the nand memory, however i cant see any simple way of determining this without rooting and using the likes of ODIN or other 3rd parties etc - linux commands etc.
I dont want to root it particularly if i can help it as i was thinking about selling it on to mazuma or the like and let them sort it out instead, but i think i might have to bite the bullet and try it.
Can anyone suggest anything that i might have missed?
Actually iv seen an existing thread which appears to match my issues, so iv installed wakelock on the phone for now which seems to be helping a bit, time will tell, however this isnt a solution but more of a work around, but im still thinking this could be a motherboard issue myself, however, as i think this phone is over 2 years old, i doubt samsung will replace the component, nor would they necessarily believe me if i turn around to them and say its the board that needs replacing!
