Hello and thanks for your time. I'll try to be as brief as possible:
I bought my gf a Polaroid 7" tablet running Jellybean 4.1.1, after a while, the tablet started freezing at times, and one time it just froze completely. I pushed the physical RESET button it has (since the battery cannot be removed) and that's where it all started. Of course, all data was lost, but it kept randomly freezing and rebooting, and after each reboot every configuration was lost again (as a factory reset).
It now shows 2 internal storages: The first says it's a total 0.0B but has 114MB data used, and the other shows a 4,3GB total and 1MB used. I cannot install/updat anything. There is no support whatsoever for this tablet (even the model is very rare PMID702DC). It is not rooted, it cannot be turned off (it just reboots automatically), I've tried going to recovery mode through ADB but it just reboots as normal... any ideas on how to fix this? My gf only used it for fb and a couple games (since it has a low 512 RAM). Thanks in advance!
Bump, sorry, this is driving me crazy. It's been a couple days and I just can't find a proper solution. Some mention something about busybox, but the device is not rooted :/ don't know what to do.

Hey there!
The last time I powered up the display of my RAZR HD and unlocked it a lot of messages about processes and apps (I can just remember a lot of Google apps and services but I am not sure if there was anything else as well) which stopped working/running popped up (I hope I translated that correctly from German). So I thought it would be better to restart the phone. I turned it off and after a few minutes I tried to power it back on. But it got stuck right at the beginning where the red/white Motorola logo shows up. It never started pulsating. I tried to start it serveral times but it was the same every time. So I laid it down for a few days to make sure the battery is totally empty and after that I tried to start it again but it got stuck at the logo again. The only solution which I found is to reset the phone but I really need the data from the internal storage. My phone is completely stock JB 4.1.2 and was never rooted or unlocked. How can I save my data? If there is a way I would love to hear about it even if it kills my phone.
need to flash stock without erasing data, you can manage that via editing the xml file.
Hi all. 1st post here.
I've been having a lot of trouble with my Galaxy Tab 2 lately. I rooted it a long time ago. Never had trouble with it. A few days ago, after charging it, I tried to start it, but when it starter, after a minute or so, it restarted. Normally the tablet only did that when it was froze due to many apps or processes being used at the same time. The problem is that the tablet never started properly after that one time. It's on some type of infinite loop. It starts, stays on for 1 or 2 minutes and then freezes and restarts. Well, i thought what most people would think at the moment: "I need to reset the tablet". I went to Recovery mod, made the format, but when the tablet rebooted, everything was untouched. No format. Odd to me. I then tried to return to stock. If it after that the problem was still there, at least I could be able to call for warranty. Odin gave me a lot of failed errors when I was trying but there was once that it said "Pass". Rebooted, still the same. Updated the recovery, tried to format, still the same. I'm running out of options right now. I don't really know what can be the problem and how can I fix it. I thought that if there was a way to format it like in recovery but using my PC it would do something (or not)
I appreciate any type of help.
Hello,
I'm having a serious issue with my oneplus one (I bought it in November, no serious issue so far).
However, A lot of issues showed up suddenly overnight (without me installing or modifying ANYTHING at all).
Here's how it goes : after a few minutes of using apps, these apps either crash, or freeze, then the phone reboots.
I've tried factory reset, wiping dalvik cache etc... but the problem is not going away.
I even flashed the stock rom XNPH05Q 64GB, but it didn't help, I still had the same problem afterwards.
So I flashed back the original rom XNPH33R 64GB, but still nothing.
I've also tried the command make_ext4fs /dev/block/mmcblk0p15 to no avail.
I really don't know what to do anymore...
I have made a logfile during which the phone freezed, then crashed a few seconds after I launched an app called "Summoner War" (which works perfectly fine on my other phone).
I am putting the logfile here in case it can help... (the crash is most likely in part2)
Any apps seem to trigger this crash (even settings triggers it sometimes)....
Should I consider sending my phone back to Oneplus for repairs?
Any help/advice would be greatly appreciated
Sincerely
Hi, I'll explain my problem quick. a week ago my Nexus 5 rebooted for no reason, upon rebooting I noticed something weird: app data configurations (app data not belonging to the user accesible memory) were all reset, it was like all apps had been freshly installed but left my pictures music and those things untouched. Wifi was working perfectly fine at this point, some form of data corruption I guess. Upon manually rebooting hoping it would come back to normal I found out wifi was behaving strangely, it would take a couple of seconds to turn on and off. After further reboots it stayed greyed out and didn't respond anymore.
So I began reading about the many possible causes and fixes. Tried reinstalling rom, reflashing kernel, going back to stock through flashing stock images through fastboot, rebooting, different radios. Nothing helped, so I decided to go a bit further and mess with the persist folder, first I checked permissions were ok and reset them anyway, then I wiped manually through a file explorer, finally I decided to do what was suggested here https://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576 with some success. Wifi was still greyed out after a fresh rom install but after some reboots it would pick up and work perfectly, until the next reboot. Then it didn't work anymore. I should note I backed up the files in persist through a file explorer and then manually pasted and set permissions (didn't know you could make an .img file of it) dunno if that has anything to do. They aren't corrupted it seems.
Unplugging the battery briefly fixed it for a day, then the next day the same problem came back without me doing anything.
Some more info:
-I have a working original EFS backup from before it crashed.
-Phone was rooted running CM11 when it happened, been using that rom for 2 years with EX kernel.
-It was a bit low on space (about 400mb left) when it happened, about 300mb were freed after it crashed. I have a hard time believing this could have caused it but maybe?
-It's global D821 16gb version
-GPS has always been wonky (if that has anything to do with it)
-IMEI and IMEID haven't changed.
-Calls and data work fine.
-When either wifi or bt work they show their correct, original addresses, only once wifi showed 02:00:00:00:00:00.
-Rebooting changes little, but powering off then waiting a few seconds and turning it on sometimes brings bt back.
-Leaving the battery unplugged almost fixed it, brought it back for some hours, went to sleep and when I woke up it was gone again.
-When performing the "e2fsck /dev/block/..." command above I wasn't prompted to fix any errors I think, output was "clean, 31/1024 files, 1125/4096 blocks" and the "make_ext4fs /dev/block/..." command reformats it without issue.
So yeah, I've tried everything save baking the mobo cause I'd rather be able to sell a semi working device than a bricked one
Any other thing I could try? Or way to check if it is indeed a hardware issue? im attaching a Liveboot log if it's of any use. Thanks beforehand.
uh I can't find the way to upload the log
how is one supposed to attach a file? im on my desktop with latest chrome
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:

and

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...
