Boot Error

Hi;

My Tab 2 froze doing an update and now will not get past the Samsung boot logo.

I have tried the factory reset (factory wipe, delete all data, delete cache) but still have the same problem. I assume there is a problem with the Android iOS itself.

I am relatively new to this, but am thinking I need to flash a new iOS to the device. Never done it, any help would be appreciated. I am sure I am not the first to have this issue and the answer is buried somewhere in the forum.

Thanks!

Which ROM did you try to install? Tab model No, recovery type and version would also be helpful to know. For installing Android versions >4.3 formatting of /system is also very important.

But it could also be a chipset brickbug, for which I hope it isn't the case.

Hello everyone, I have a problem, that my P3110 won't be recognized by any PC. I tried a Win10 and Win7 Computer, but neither even finds the Tablet when I use Kies. And of course they also don't recognize the tablet when it is in download mode (tried Odin3 and Heimdall). Do you have any suggestions, what I might do to change that? Charging works at different USB ports...

Thank you!

Galaxy Tab 2 p3100 Crash all apps

Hey, Im new here hope someone can help me with my huge huge issue, first i want to say ty if you want to help.

The issue is when I turn on my tab all apps start crashing (system apps and download apps), my tab is rooted with CyanogenMod 10.1.2 stable, I tried to flash from recovery using .zip and adb from my computer, didnt work.

I wiped off all system/ data/ cache/ dalvink/, nothing happend.

I tried to install another recovery using odin, but changes arent save.

Unistalling some apps and then reboot, changes arent save apps are there.

I cant copy new files to my tab card, I cant delete any file on my tab.

It seems all files are locked.

PLEASE HELP ME I LOVE MY TAB :crying:
[Galaxy Tab 2 Q&A, Help & Troubleshooting] tetakpatak:
Take it easy, mate- we need a bit more precised information what exactly you did. So what did you try to flash, what did happen and which recovery and version do you use?

??

As you have CWM already, you can use zip files to flash an updated recovery version, then reboot recovery after that.

I want to have my tablet run without any google apps,and that respects my freedom,which means no google analytics in settings, no sketchy connections at kernel level etc.

So far I am on official cyanogenmod 5.0.4, but sometimes it slows down and is unresponsive. And generally slow. But the battery lasts weeks (i am not exaggerating!!) if I am not using it.

Maybe it has to do with the memory leak in 5.0 lollipop?

if I were to use a ROM that respects my freedom, what would you suggest me?

There's a slight way to get rid of google:

Don't setup a g+ account

Don't flash gapps, use f-droid instead for example https://f-droid.org/

Disable some google settings (like access on location)

I am not sure if "Freecygn" still is worked on, googleing it won't hurt... Well... Better use i different search engine like https://startpage.com/

I'm already using startpage.com and fennec fox on it [a fork of Firefox for android with telemetry removed].

Freecygn doesn't work anymore with cyanogenmod, and even if it did, cyanogemod is a lost cause:

Hi all,

I have already stated my concerns at http://xdaforums.com/galaxy-tab-2/help/solution-gt-p3100-firmware-upgrade-t3246212 without success. So I am coming here with the same hope to get some guides to hopefully revive my GT-P3100.

[Galaxy Tab 2 Q&A, Help & Troubleshooting] BoredDude:
Hi there guys, i was running andi's omni build rom, but then the tab just went plain unusable performance-wise, i thought it was the rom so i changed it to aosp, but i have noticed it's very laggy and performance is not actually good.

I use my device mostly for reading purposes, using dropbox for sync.

I found this http://xdaforums.com/showpost.php?p=63877240&postcount=2 TL;DR version says performance was nuked by the Trim bug.

So, i have the following doubts:

Is that actually right?

The only way to recover performance is installing stock rom without moddifications?

Would performance return with a modded stock rom like Galaxy project?

Also, i really hope this tab can make it to marshmallow so we can have doze and fix lollipop bugs, and related to this problem...

I assume Andi is waiting for CM13 to release officially so he can start building, If we ever get to see 6.0, would it have the same performance issues because of trimm?

This tablet is old but i can never thank enough to wonderfull developers like you Andi, that make this thing still viable, you're the man.

Yes, Samsung USB drivers are installed and i've tried kies too, currently i'm running stock jelly bean 4.1.2, cwm version 6.0.2.7, when i said that i could access recovery i meant that every option in the recovery doesn't work, for example if I wipe all data/factory reset it says that wiping is successful but when i reboot i can still see all the old files and apps, and then it starts to bootloop again, and the same happens with every other option, i've tried to flash a custom ROM from external SD card but the dame thing happens
[Galaxy Tab 2 Q&A, Help & Troubleshooting] tetakpatak:
Ever more people have been reporting recently that their internal memory got corrupted.

CWM version 6.0.2.7 is outdated and it cannot flash any ROMs newer than Jelly Bean, so the suggestion is: updating recovery, downloading some nice custom ROM (for example: SlimKat 4.4.4 with Slim Addons for 4.4.4), then fully wipe the tab (system, data, cache, dalvik) and try to flash the new ROM with Gapps.

My P5110 had BTW quite similar problems when I installed once for few hours stock 4.1.2 just out of couriosity. However, it was without bootloops, but stock 4.1.2 managed to corrupt my tab's data partition then.

Good luck!

[Galaxy Tab 2 Q&A, Help & Troubleshooting] tetakpatak:
Your recovery can flash all ROMs previous to KitKat (4.4.x)

You don't need Odin to update the recovery, copy flashable zip of the recovery (not *tar.md5) to your external SD card, insert it then into your tab and install zip, reboot recovery.

Logcat & dmesg would show what's wrong,

But i think your internal storage is broken. Samsung uses known faulty MAG2GA emmc on 16 gb tab 2. From kernel source they released it's not fixed kernel side as far as i can tell.

Your only way might be someone with a jtag who can update your emmc firmware, else replace the emmc (but not sure if it isn't to expensive).

It sounds to me very much like the faulty chipset MAG2GA has given up the service. Maybe [MENTION=5153662]Android-Andi[/MENTION] can briefly check your post and confirm.

If so, it would be a hardware problem so only service could replace it.

I have no idea if it was Samsung's hidden "strategy" to sell more devices, but that brand has been using faulty chips quite systematically:

except in Tab 2 (both P31xx and P51xx) also their flagship phones like the Galaxy 2, Galaxy 3, Note 1, Note 2 etc had faulty chips with an eMMC brickbug, or even SDS (sudden death syndrom), check Google search.
