[MENTION=5018170]p0nc[/MENTION] now the experimental part, not sure if it works and what will happen

- maybe a not booting device, but you told it's not booting anyway

- maybe it won't change anything

If you like to test follow next steps:

##### Run Parted from ADB Shell

adb shell
parted /dev/block/mmcblk0
u s
p

##### Delete and re-create FACTORYFS (/system) - we don't change the size, we will use same start and endpoint

rm 9
p
mkpart 9 1581056 4448255
p
name 9 FACTORYFS
p

##### Delete and re-create DATAFS (/data) - we don't change the size, we will use same start and endpoint

(parted) rm 10
p
mkpart 10 4448256 29728733
p
name 10 DATAFS
p

##### exit parted

q

##### create ext4 filesystem

You can use adb shell to do, but much more simple:

In recovery now "format /system" and "format /data and data/media".

Please try if you now can flash and boot a rom - don't flash anything else.

Would be great if you can share the terminal output and tell your experience.

The hidden partition has a different file format (ext4 instead of ext2 in your case). Does that have to do with anything?

[MENTION=220904]andi[/MENTION],

Same is the problem with my tab. I cannot rm any partition.

I tried to format it with ext4 anyway but parted version was not supporting ext4 fs.

Tried to update parted with latest one, did not work.

Tried to tune2fs /system & /data. All parameters are fine. Changing fs features was not needed.

Tried to dd new recovery, it was successful but not booting in new recovery. I can see all recovery version that I have installed in ROM Manager. I get enough time to select new recovery & reboot in recovery before tab reboots on its own. But still it goes in older recovery.

Though I tried almost all mkfs possibilities, I feel mkfs.ext4 is much needed but not sure how to get that in busybox.

"prdepune You have installed cwm 6.02.7 ? That means you have never installed a KitKat or lollipop based rom until the brick appeared? This information is important."

As I stated earlier, I have not flashed anything beyond JB. This issue started on its own. I did not provoke it brick itself! :D

Any thought?
[Galaxy Tab 2 Q&A, Help & Troubleshooting] tetakpatak:
Samsung seems to feature faulty chipsets systematically to ensure survival of its service.

As the lifetime of the flash memory is also limited, it is hard to say which of both causes the problem.

If it happens with my P5110, I will probably send it to the service to replace the motherboard if they can ensure me I won't get MAG2GA chip anymore.

[Galaxy Tab 2 Q&A, Help & Troubleshooting] fredy66:
You have never installed an other android version based on android 4.3 like cm 10.2?

Hmm did you use tools like fstrim?

If not this brick was not the mag2ga trim bug.

This bug happend one year ago with some nook HD tabs. But one year is gone.

A lot of p3100 got this bug. But no p3110. But more p3110 were sold.

I think we don't have a problem with trim.

[MENTION=5153662]Android-Andi[/MENTION] and [MENTION=5117218]tuxafgmur[/MENTION] maybe the p3100 versions are writing more datas to emmc during normal use of the tablet. What do you think? We should make a kernel with the possibility to boot from sd card. (mounting system data cache) If emmc dies we could prepare a SD card and the tablet could be used without the onboard emmc .
[Galaxy Tab 2 Q&A, Help & Troubleshooting] prdepune:
Well, that sounds good to me!

But is there any solution to that? All symptoms are similar to TRIM.

BTW, I had flashed some custom ROM which was running good for a year. Upon the brick, I flashed to JB Stock ROM.

Let me know if you have any suggestions!

How to swap if you can't flash a new boot.img?

Maybe we need a modified bootloader to get back rw access...

Yes sure it's not possible for the already bricked tabs. But for the still working ones.

Only an idea because like you've said emmc will not life forever.

If the emmc is write protected from the chip design its also not possible to flash a bootloader.

Attaching dmesg upon normal reboot in recovery from ROM ... log1.txt

dmesg upon crashed reboot ... log2.txt

I dont see much there .. could someone have a look & see what is crashing/rebooting the tab?

Update

Brought my Tab 2 to the Samsung Service Center last week. They said my internal memory had corrupted and the solution is to replace the mainboard:eek::eek: Then I decided not to replace the mainboard since the cost is very high. So my Tab 2 is become unuseable now, I'm going to make this device as an experiment device since I have bought a new phone. I'm open to any solution and willing to try everything so you can fix the eMMC TRIM bug :D:D
[Galaxy Tab 2 Q&A, Help & Troubleshooting] SirKunon:
If nand is in read only mode you can't flash anything through tab hardware or/and software layer. Maybe connecting manually via so called spider directly to nand module on the mainboard will allow flashing anything. But if some cells of nand are faulty you need to bypass them building a device (faulty nand) dependent partitions information table (pit file).

Long time ago flashing dead PC BIOS module was performed that way. You should ask in private service centers. I don't think they will know how to build a new pit but if they have needed hardware to connect with nand than you can deliver a proper pit and PDA.

I don't know this nand are BGA type, if so then you need to find service specialized with removing ball grid array electronic parts. I think it's not even worth to try. It will be to expensive.

Can you please share, how much did service want to charge?

In Indonesia, replacing main board price might be vary depend on the location of ssc. However most of them charge around 100-120 USD.

Replacement of emmc chips with some Chinese emmc (V3W00M type) cost 60-70 USD for 16gb and 120 USD for 32gb type (no one reported for this 32gb type actually) .

Edit:replacing emmc were done by local phone services
[Galaxy Tab 2 Q&A, Help & Troubleshooting] Sabhastar:
[MENTION=6064460]jak978[/MENTION] that's right, thanks for your answer. Does it work when you replace the eMMC that done by local phone services? How long it will last after you replacing the eMMC?
[Galaxy Tab 2 Q&A, Help & Troubleshooting] jak978:
[MENTION=6386420]Sabhastar[/MENTION]

Yes, everything works fine, as reported. Some using dualboot normally.

They provide 1 or 2 month warranty, no one reported broken emmc yet after replacement.

an example of local service is http://emmc.unbrickandroid.com/index.php?dir=SAMSUNG/P3100/

I had the same problem with my P3100. even after you remove the data or flashing new roms via recovery or odin. after reboot it will return to its state condition. just like frozen. Actually on several discussion forums in mind that this is most likely caused by a write protected at EMMC (cmiiw) or several bug on emmc listed by CM teams ( http://wiki.cyanogenmod.org/w/EMMC_Bugs ) . I am not an experienced person, but I find some of the threats that related to this problems and might help. but I can not do it myself due inability me in terms of programming.

Hope it usefull:

In my stupid opinion, after successfully unlock write protected on emmc, then we can remove all the data and re-flash the kernel with some patches that have been done by samsung. I'm using stock rom 4.1.2
