Galaxy TAB 7.7 / P6800 memory failure? - Android Q&A, Help & Troubleshooting

Hello people.
I have a problem device and I have post this under Tab 7.7 section, yet still no reply until today, and i decided to post here, in case anyone of you hv any idea on this.
Device : TAB 7.7 P6800
ROM : Carbon ROM build 12/12/14
ROOTED
CWM 6.0.3
Ok so I woke up few days ago to found out that my Whatsapp suddenly fc. And when i open it back, it shows that my chat backup are messed up and i need to restore it.
And while doing that, it started to reboot by itself.
I thought it will be okay after that.
It not.
It keeps rebooting, then Dropbox fc. Few seconds after that, reboot again.
power on, another apps fc. after few seconds, reboot again.
It keeps rebooting into the same state when i woke up that morning. Wifi turned on, few notifications on panel, (thou i keep clearing it everytime when it power on)
Now ive tried wipe data , wipe cache, everything in CWM. but it keeps rebooting into the same state!
Ive also tried flash with stock rom via ODIN.
Guess what?
It appear PASS on ODIN, but when the tab powered on, is still went back to the previous same state.
Ive google around and some said it is the sign of memory flash fail or smthing.
anyone maybe could tell me what am i dealing with here?
im on dead end.
THANKS

[Q] Phone completely freezes after ICS update. HELP!!!

Hi guys,
I have a huge problem. I had a stock GB firmware customized by Optus (carrier in Australia) on my S2 I then decided to change to the new ICS 4.0.4. I downloaded the stock unbranded firmware from SamMobile (Australia 2012 September 4.0.4 I9100XWLPW, I9100XSALP6, XSA) I updated using Odin. Before I did the update I reset the phone, did the update, it all went smoothly. After the update I reset the phone again and then proceeded to reinstall all my apps and restore my contacts, sms, etc.
The phone works and all functions on it work, however now very randomly the phone would totally freeze. The phone would be in standby, the screen would come on and it would be frozen. The screen stay on all the time and it does not respond at all. It will stay frozen until I restart the phone by pressing Home+power buttons to restart it.
After restart it all works fine for a few hours, sometimes a day and would just lock up again. The phone is not rooted and as I said i just changed the firmware from the Optus branded GB 2.3.6 to unbranded stock ICS 4.0.4 by using Odin.
Is there a way to find out what is causing the phone to lock up like that? Any suggestions would be helpful.
and then proceeded to reinstall all my apps and restore my contacts, sms, etc.

I hope you haven't restored any data app?

I made sure that I didn't restore any data apps. The only apps that got restored are the ones that get automatically restored by Play store.
I have disabled the live wallpaper that I had and it seems to have stopped the freezing for the moment. I will report on what I find out.
In the mean time if anyone else has a similar issue or has a definite solution please let me know.
Thanks
i know this is a resurrection, but don't see it has been resolved.
also found same/similar problem on another topic, but no resolution either.
couldn't find any resolution anywhere on the net, but possibly i'm just missing it (searching for wrong parameters?)
anyway, a friend of mine bought second-hand (third or even fourth hand to be precise) i9100 with 2.3.6 (stock KI3) on it. the guy who sold it to him said something like: "it works best on 2.3, on 4.x it's buggy".
it was working fine, but friend wanted newer OS, so we tried update. it didn't work, and i found out CSC was broken/missing. somehow i managed to repair it, and update was finally working, but was unable to find any for our location.
so next step was to find stock rom that would work on the device, and then i tried four different 4.1.2 stock roms from this topic.
after flashing it through odin, every one was acting fine, until couple of minutes after it started freezing or rebooting randomly.
then i tried flashing CWM, and flashing from sd card, but it was all the same.
wiping data, cache and dalvik cache, prior to flashing. wiping data after flashing...
nothing seemed to work.
GB works rock solid, ICS works better than JB, but stills it freezes or restarts randomly.
tried CM10, but all the same, except it works a bit faster then official JB. but who cares about speed if it freezes/restarts constantly?
back to who knows which build... freeze... samsung galaxy s2 - i9100... with yellow triangle... booting stopped.
so i decided to dig deeper, trying to find hungarian stock build (country we were told the phone came from) not being sure that KI3 is what the phone came actually with. i found 4.0.3, put it on SD card, wiped data, cache, flashed CWM, wiped data, cache, dalvik cache, flashed 4.0.3 from sd, wiped data, booted, entered location for updates - hungary. update found, hooray... downloading... installing... rebooting... working?
nope... it's worse than ever. trying to log onto google account. typing in email add.... freeze... switching phone on - freeze... thinking about... freeze.
i couldn't sit still. yellow triangle, all those reboots/freezes... at least i wanted that triangle gone, and without a JIG, there was only solution for me was to try triangle away. it wasn't available for download in my country from play store, so luckily xda was there.
somehow i managed to download it from the device, install it, click remove the triangle... it did it's magic, rebooted... and miracle happened!
no more freezes.
so i started torturing poor phone, benchmarking, playing games, listening to music.... it seemed stable for about an hour.
so i said to myself:
- it's possible that previous owners tried to upgrade it to newer firmware, and somehow screwed up the bootloader, which was fixed by this app? maybe that was all there was from the beginning? why not try putting 4.1.2?
and i did... took 4.1.2 spanish build from already mentioned page above, flashed it... and voila. working JB... torturing the phone... playing with it... hour passes, another hour...
friend wakes up... takes his phone in awe, starts playing with it.. we talk a bit... and then that look it just froze again!
from that moment on, the phone again starts restarting or freezing randomly...
and, yes, i still have no clue what could be the cause. it doesn't matter if wifi is on or off, if you're talking on the phone or not, bluetooth and gps are always off. only thing that he noticed is that it usually happens while he's using the phone (meaning: operating the digitizer or buttons). if he starts music playback and not touching buttons or screen, it will probably play for hours.
one more thing, but i doubt it would be the case. the battery in the phone is not original one that was shipped with it, but a quality replacement.
it doesn't feel as if the phone is overheating... so i don't know what else i could do with it.
for now, it's back to 2.3.6.
we both lost a week, torturing ourselves with this problem.
i don't know is there anything i could add more?
all suggestions are welcome.
cheers
Maybe try kernel cleaning script and try philz or siyah kernels.
You shouldn't have to flash a custom kernel so your phone won't freeze, but yes, you could run a nuke script in order to wipe clean all custom ROM's leftovers.
Try flashin' jb via mobile odin, see if it keeps freezing up on you. If so, nuke it up.
Sent from the little guy
i'll try them out.
probably for the weekend, if not sooner. will report back here with info.
any other suggestions are also welcome.
thanks a lot.
cheers
ok, so here are some updates.
i finally got my hands back on my friends phone, and tried nuking remains of older flashes.
following that, i flashed stock spanish rom from above mentioned page, updated after installation to spanish update... and after a few minutes, sudden reboot...
so, went back to nuking, and flashed stock hungarian 4.0.3 i found elsewhere (mentioned in my earlier post. don't remember origin... if i find the link on another computer where i downloaded it on, i'll post the link). tried updating, says no updates found.
started torturing the device. it seemed solid, but battery reported it level was low, so hooked it up onto charger and all seemed well. but phone seemed a bit too hot.
after few minutes (this was all about half an hour to hour after flashing to 4.0.3), again freeze.
after rebooting the phone, battery was at 9%, as if processes were draining battery faster than charger recharged it.
so, i figured i gotta try original battery. so i switched his battery with genuine from my phone.
phone seems stable and less hot, for now.
still checking if it is going to freeze or reboot again.
it's about one hour since battery change. still on charger and using wifi and playing around with apps.
i'll check in with news later.
cheers
I have the same issue.but my battery is original.
What I noticed that the phone stuck when I receive an update notification.
Can I stop softwsre to ask for updates? ???
Sent from my GT-I9100G using xda app-developers app
^go to settings, about device, software update and detick auto update. that should stop it from trying to self-update.
ok, so here is an update to my friend's phone status.
currently on hungarian 4.0.3. about 3-4 freezes/reboots a day. sporadic connection breakups during calls. also, when we talk i can hear myself back. this brings me to conclusion it has to do with modem firmware. i found this topic, so i'll try putting that and see what will happen.
if that doesn't solve anything, my question is this: is there any way of knowing which firmware/rom was originally put on the device, since i don't know the real background of the device? i.e. some way of entering IMEI and finding out what should be on it?
cheers
EDIT: tried KH3 modem, no changes... i could still hear myself while talking to my friend on that device. also, it froze couple minutes later. going back to 2.3.5-2.3.6 for now.
so after couple of months, i finally got my hands back onto this phone...
gave my friend my phone, so i could play a bit with this faulty one.
i have played with it for a couple of days now, and here are things i've tried.
i received it from a friend with 2.3.5 on it which had triggered custom binary counter. he's been using it for couple months without any problems.
so i rooted it and installed triangle away again... reset counter, cleared and flashed hungarian stock (telenor) 4.1.2... random freezes again.
tried several stock roms, mostly hungarian ones (4.0.3, 4.1.2). even reformatted with .pit file... random freezes.
reformatted again with .pit and put XXLSJ, installed stability test and let it run...
cpu stability test 15.5 hours no problems, no freezes. then i realized it didn't have a sim card, so i rebooted phone and installed sim card. let it test cpu+gpu for 9 hours... no errors, no problems, no freezes.
so i thought, maybe it's all fine? but it wasn't! as soon as i took phone into my hands and started going through menus it froze!
so i tried SGII_repair, rooted and did "repair"... but nothing changed... still random freezes.
if i just let it do the stability test, it'll probably work forever.
things i've noticed:
- serial number is wrong format (14 hex digits instead of 11 alphanumeric)
- during stability test, cpu frequency dropped from 1200 to 800 mhz (maybe because it was getting warmer? 42-43C during cpu only+charging battery, and about 39-40 during cpu+gpu test)
i tried to find out which firmware is latest according to serial number via kies, but it gave me error.
i know it's from hungarian market, but don't know which exact part of it (branded or not).
don't know what previous owners did to it, and don't have backups of original efs or anything original.
i just want to make it work, don't care much about custom firmwares. i'd be happy even with unrooted stock... just for it to work!
i have no ideas what else to do.
anyone?
finally, as i couldn't resolve the problem, i returned phone to 2.3.5 and sold it as is.
thanks to all people who tried to help.
cheers

[Q] Phone Freezes

Hi to everyone..well..as the title says my phone keeps freezing after seconds it boots. i was on PA v3.6 and decided to flash the newest release so i did.. after that it's been only problems. i did the wipes, but it constantly freezes.. so i decided to go back to stock and try again.. so i did with odin, but it keeps freezing even when the first settings pops out. i don't even install any apps. it just freeze, even if i reboot the phone and leave it to deep sleep i find myself with the same problem. i've been flashing custom roms since i bought the galaxy s1 and i never had any problems. i tried the dummy file thing but it keeps happening. does anybody knows how can i fix this?
Freezing is usually the memory controller working around bad memory blocks. Try reading the 'unusual freezing' thread in the general forum.

Bricked rooted Galaxy SII without CWM

Hello, let me describe my problem.
Some months ago i rooted my SGSII with stock rom to remove facebook and other unnecessary apps, but I didn't installed CWM. Yesterday I had a small accident. I dropped my phone on the wet floor and two problems occured. Power button didn't work and phone couldn't connect with network. After having dissasemblied and dried it inside, power button started working, but phone still couldn't connect. So I decided to make a full wipe. And here's come my problem. After wipe my Android 4.1.2 is able to go through initialisation process (language selection, wifi password etc.)
but after this it gets stuck and bootloop occur.
I tried to fix the phone using Odin, but after connecting to computer, it shows that device is unknown and Odin don't see it. I also tried to find way to install CWM via stock recovery, but it's propbably not possible.
Please, help me

Encryption unsuccessful random! Need help. Galaxy S3 CM 12.1

Sup guys, so i just had a really strange problem that popped out randomly, i was watching a youtube video and i had to help a person quickly and when i came back just a minute later i saw my phone showing encryption unsuccessfull when i pressed the power button to turn my screen on. Well it said to factory reset my phone, i don't store any important data on my phone anyways so i just went for it, and it restarted went to my TWRP recovery and tried factory reseting it, to no success. It basically failed to access /data/ and other directories and i can't see any files in them through recovery. And so i can't even factory reset it, i can't install a ROM cause the partition is corrupt i assume. How can i "unbrick" this? I was running the good old Temaseks CM 12.1 ROM, has been working fine for a looong time. My PC recognizes the phone but i can't access any data, it just shows that it's connected, odin doesn't recognize it.
Can somebody help me please ? I use my phone alot and it's really important.

What could be wrong with this phone?(Freezing, restarting, doesn't detect carrier)

Ok hello i'm pretty new to this, but I have looked around quite a bit and nothing seems to help. So my friend gave me this Galaxy S6 edge(more specifically the SM-G925I - TCE Mexico (Telcel)). The issue with this phone is that it freezes then restarts randomly and it also doesn't recognize the carrier. It recognizes that theres a sim but the carrier is not recognized and I don't have access to mobile data. The bigger issue at the moment is the crashes though. I already tried resetting to factory defaults, booting in safe mode, wiping the cache and wiping all the data/ factory reset from the recovery menu. I thought it was the OS or something so I installed twrp wiped EVERYTHING(pretty sure I did since when I rebooted twrp told me if I was sure since I had no os installed) and installed the official 7.0 firmware update from sammobile. It was previously 6.0.1 and I thought having a different version might fix the issue. Yet the issue remains, within a few minutes of me using it it freezes, turns off, and reboots. At this stage I might you might think its a hardware issue but when i'm in recovery or download mode it doesn't turn off. Also I decided to leave it charging when I left for work and when I came back it hadn't turned off at all. I checked the uptime and it was at 7 hours and yet within a few minutes of me checking the settings it froze and turned off. I'm not really sure what to do anymore i'll probably take it to a service center to see whats up but I wanted your opinions first. Thanks.
