Hi Andi, In stalled todays Rom with your suggestion of FOrmat data instead of advance wipe....No reboot since 3 hours. Working everything..... Thanks,,, after so many weeks this is most stable and i think you found the problem...Thanks a lot...let you know if anything found...

Hi,

The latest build is a non starter for me.It just reboots the moment the initial screen appears,Even if I managed to get past the initial screen the Google login wouldn't get past checking (no matter how long I leave it ) !

I also did the above without much of a result,finally had to revert to older builds.

[MENTION=5153662]Android-Andi[/MENTION] this time not much of "!" ,So can you please answer or will you ignore like you have done in the past ??

Hello, I've installed this ROM cyano v12.1 on my tab p3110... It works perfectly, just only one problem: when I watch a basketball game on the official NBA app audio it's faster (only a few tenth of a second) than the video, they're not synchronized. On the youtube app or every other app audio-video sync works perfectly...

On my previous Rom (SlimKat 4.4) there wasn't this problem, what can I do?

Wipe cache/dalvik doesn't do anything

I've been reading a lot (just read the latest 30 pages of comments) just to know how to get rid of constant reboots as soon as a heavy opens like Chrome, Facebook, etc.

I got no solution except to uninstall Facebook. Am I missing something?

Flashed to the 09/19 build too. Still reboots are constant.

(Update: Seems fine after Facebook uninstall. Is there any remedy for this?)
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Android-Andi:
[MENTION=5329504]feverhotsam[/MENTION] to update to twrp just flash the twrp zip for your device inside philz touch.

About FB: use Facebook lite ;)

Thanks Andi but still reboots are happening. There is no Facebook at all. This issue suddenly came in after 2 months. Yes, II was using a 2 month old build.

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] ASHURiCAN:
One of my tabs is like killed. Firstly, it bootloops, it finally boots after a hard reboot. When booted, all apps and system apps constantly force close. The device is impossible to use. Booting to recovery works but all functions (formatting, flashing, backuping and recovering) are like placebo, I mean they do the jobs but nothing is really done, when I reboot to system, it's exactly same, it's untouched and all the apps still there. Nothing has been done. Even flashing another recovery version lets the recovery untouched. Very strange situation. Deleting directories same. It's like all is read-only but then I don't understand why all the jobs are shown as done without errors. There is worse, flashing Stock ROM from SAMMY or anything else in Fastboot/Download mode via PC ODIN runs until the end (green PASS after more than 1 hour) but after reboot, nothing has been modified, system and apps untouched, CM12.1 still there and unusable, all force closing [emoji33]

Device is P3110.

CM ROM is the one just before the last.

Recovery is TWRP 2.8.7.1 (the one you themed [MENTION=5153662]Android-Andi[/MENTION])

I'm lost, I tried all, even Fix Permissions and Heimstall. Please [MENTION=5153662]Android-Andi[/MENTION], tell me what's going wrong? Is my tab died? Is it possible to recover it? Are there log files I could post that may help to understand what's wrong?

Thanks for any help. I like your ROM Andi and it works very well on my P3113 (was working very well on my P3110 also).

Cause of soft reboots

Even after a clean install I incurred continuous unusable reboots. It seemed to be because of Music player and suspected corrupt Media Storage. I had faced media storage related issues since the begining of CM 12 like multiple entry of same songs etc.

After I managed to reach the application settings , I disabled Music . I have not had any reboots till now.

You happen to have a link [MENTION=5153662]Android-Andi[/MENTION]? I'd like to give that a try (I do have the required equipment and tools to JTAG a device).

Reason: Friend of mine was running your CM12.1/TWRP on his 3110 - somehow he flashed back to stock 4.2.2 (don't ask me why, I only get to deal with the outcome of uneducated brainfarts once things are broken - usual fate of techs) and now the device behaves like a eMMC brick, though it was in flawless working order before the "back to stock" flash... the stock recovery claims a "Failed" on the wipes, system boots and crashes on the lockscreen. As much as I can tell the NAND is read-only though the chip (8GB model) isn't really known to be affected by the "eMMC brick bug" (at least the model of the chip was never listed in the posts you made about it) - hence why I can't either flash a custom recovery.

It would be interessting to try and see if the chip(s) really turn bad that blazing fast (~2/2.5 years old)... I mean... I have a old, modded, ASUS EeePC 701 4G sitting around that has a 4GB on-board eMMC (running Android-x86 4.4.4) which is still working perfectly fine... if the chips really turn bad that fast then it would seem the parts Samsung chooses are "Shenzen market crap" grade.

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] BoneWithABeagle:
Well, while that thread wasn't particularly helpful I managed to get it back to work... seems the scatter-list of the eMMC (M8G2FB, 0x000015, just for reference) was shot. Cleared the eMMC (total erase), re-partitioned, re-flashed and it's back up and kicking - though I can "kill" it again by simply flashing 4.2.2 (Samsung's firmware, not "MicroDelta") instead of 4.1.2.

That being said... resurrecting dead M8G2FA's (or any of the other chips known to be affected by the Brick/SuperBrick Bug) could turn out to be a futile attempt. From what I gathered there's a beyond-slim chance to maybe get them back to work by clearing the eMMC and repartitioning afterwards... and even if you manage to get it successfully done at the JTAG level there's still a rather good chance that the device either won't come on at all (no download mode because the eMMC failed initialization) or comes on and fails flashing (ODIN error while trying to write the firmware). I think it is pretty safe to suggest to put bricked devices to rest. Replacing the motherboard is not a economically viable repair, given you get a spanking new tablet for the money having more "oomph" than the Tab 2.

In short: spare yourself the money unless you have a _real use_ for a JTAG box (like the famous RIFFbox).

Glad you resurrected yours. I think the emmc on mine maybe dead. I asked in q&a forum here:

http://xdaforums.com/galaxy-tab-2/help/firmware-upgrade-encountered-issue-help-t3196706

But got no comments. There are similar threads all with no positive outcomes but as I said q&a seems very quiet now.

I know this is a dev thread but thought it worth a final ask. As I don't have access to a JTAG box and as you say it would be cheaper to eBay another tab2 than buy a JTAG box I think it is time to dump it!?

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Android-Andi:
thx for your feedback. Does tab2 have M8G2FB emmc? 16 GB models all seem to have MAG2GA, so not sure what's placed in the 8 GB models
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] BoneWithABeagle:
[MENTION=4305518]blackkj[/MENTION]: I replied to your question in your thread to keep this dev thread somewhat tidy.

The P3110 I dealt with _is_ a 8GB model... eMMC is a M8G2FB part, device seems to have been made late 2012 (bought around March 2013).

The MAG2GA is listed in the CM Wiki as "TRIM bug", leading to "device brick" (how surprising). I think there's a good chance to JTAG them back to life as that doesn't look like a severe problem (at least it's not the dreaded "secure erase" bug where chances of getting it back to life are near zero - or 50:50 at best depending on humidity, air temperature, stellar constellations and sun flares. For as long as you can dump the contents of some of the required partitions (userdata, SBL, ... everything not inside the standard firmware update file from Samsung) to then NULL the eMMC to re-partition (accordingly to the corresponding PIT structure) and re-flash it should be doable... given you can inject a "non-TRIM" kernel and recovery so you don't power back up with faulty software again.

Keep in mind that this requires either a JTAG box (they aren't cheap, Andi!) or you having some knowledge about electronics and Linux in which case you can get away with something like a Raspberry Pi or BeagleBone (any ARM board having customizable GPIO pins you can turn into a JTAG connection along with the jtag toolchains) or simple "protocol converters" like the Bus Pirate which you can set to talk "JTAG" given you run Linux and have the tools compiled up.

EDIT: Like I wrote in my reply to blackkj: I'm pretty sure the problem with the tablet wasn't the eMMC... I'd dare to place a bet on something being very wrong with the CSD in Samsung's 4.2.2 firmware package as it either "kills" the tablet again right after resurrection (AOSP recovery fails wipes) or after a few reboots (system boot-loops due to read-only NAND).
