Well, I got my tab working, no gapps, 9gb data partition ad cm10. Trying to identify what is making it hang to where I have to hard reset. It seems to happen less frequently as I use it. Once I figured out to navigate to and install fdroid, I was home free... will I get the motherboard? Yes, once I confirm they have the part I need. I Amy take mine apart as the teardown instructions online are for the Verizon version, and I think it's possible the motherboards may be different. We may have a motherboard like the one in the picture. Will let you know when Im comfortable taking my machine apart. Next few days. I also emailed the seller, so when I hear back I'll let ya know!

Thanks for all your help! SO glad to have my tab running again.

URGENT pleasee

please help i'm stuck on this step...

---------- Post added at 11:58 PM ---------- Previous post was at 11:52 PM ----------

that what I've got while working on FACTORYFS

and BTW when I try to install any rom it's freez on FACTORYFS.img on odin :( please help
[Galaxy Tab 7.7 General] Androguide.fr:
Judging from your screenshot you're trying to create a partition were one already exists, that's why mkpartfs tells you it can't find any space to put it.

Simply do "rm 9" while in parted to delete your FACTORYFS partition before attempting to re-create it.

Also there's an other error in your command, you can't directly create ext4 partitions with mkpartfs, you need to do

mkpartfs primary ext2 281 1153

Good luck with your brick, read the OP carefully and you'll revive it ;)
[Galaxy Tab 7.7 General] massdown:
thanx for quick replay :)

I finished everything as u said and when I try to install a firmware using odin its still stuck on FACTORYFS.img :(
[Galaxy Tab 7.7 General] Androguide.fr:
Man... READ the OP and forget about Odin, you'll never be able to use Odin on your tab anymore.

You need to flash using a custom recovery (CWM or TWRP)

By the way you might need to re-partition again as you tried to flash through Odin.
[Galaxy Tab 7.7 General] massdown:
will... i'm not giving up easily , i'll start all over again , hope when i'm finished I can find u online for help :).

really THANK YOU.
[Galaxy Tab 7.7 General] massdown:
here is my partition table

after flashing rom , it's freez on Samsung galaxy tab 7.7 logo for more than 15 min.

I restart it but no use, tried to run e2fsck command for both /data and /system and restarted again...

still freez on that logo :( any help!!
[Galaxy Tab 7.7 General] Androguide.fr:
Which rom did you flash ?

Usually, after a successful flash, the tab gets stuck on the rom's bootanimation, not the Samsung bootscreen

Try to flash a light weight rom (avoid stock-based roms).

Appart from this, if the output of e2fsck is clean on both /data and /system (~ < 5% non-contiguous), and that after getting a clean output you flash a rom through recovery and the flash goes to the end without being stuck then the tab should boot properly

Otherwise, you might need to make clean /data & /system partitions again by removing and re-creating them as before

You can also try to go to recovery/mounts & storage --> mount /cache then run e2fsck on your cache partition (stay in the mounts & storage section of the recovery), it might block boot if the cache partition is "dirty".
[Galaxy Tab 7.7 General] massdown:
paranoid android 2.23

it was 0.2% non-contiguous

I don't have mount /cache on the list ?! only unmount /cache :rolleyes:
[Galaxy Tab 7.7 General] Androguide.fr:
Yeah unmount it, my bad.

Please try with PA v2.50 (latest stable build), can't remember if there were problems with v2.23, built this one a while ago. But I can confirm v2.50 works properly (using it on my (un)bricked tab)

It's late here, gonna go to sleep but I'll be there tomorrow if you're still stuck then.

Good luck
[Galaxy Tab 7.7 General] massdown:
OMG it's WORKING , MY TAB IS ALIIIIIIIIIIIIIIIIVE :D

I used PA v.2.53.

i'll complete your amazing tutorial later , it's 3:35am and I have to sleep now

man really really thank you for your help.
[Galaxy Tab 7.7 General] Androguide.fr:
You're welcome, glad you got it working ;)
[Galaxy Tab 7.7 General] massdown:
now reached 5) Expanding your internal storage

how can i move the end value of the DATAFS while HIDDEN partition starts where DATAFS ends ??
[Galaxy Tab 7.7 General] Androguide.fr:
You can't, that's why it's advised to start trying to recreate the partition from a value closer too the beginning of the original size then to the end.

Anyway don't bother with this part, your tab will freeze when downloading anything on the emmc.

So we're going to trick the tab into thinking that the external SD is the emmc, so we can get up to 64gb of internal storage and no freezes :)

Here's what you need to do :

- Open a file explorer (adb install if you don't have the gapps installed), and go to /dev/block/vold/

- Note the name of the 2 files (179:25 & 179:24 for me)

Write the following in a new text file (I recommend using your computer for this, android text editors often leave hidden characters)

#!/system/bin/sh

mount -o remount,rw /
mount -t vfat -o umask=0000 /dev/block/vold/179:25 /sdcard
mount -o bind /data /storage/sdcard1
mount -o remount,ro /

Save it and name it something like 99int2sd (don't forget to replace 179:25 with yours if different)

- Put this script in /system/etc/init.d/ and set its permissions to 755

Now, for some reason, the init.d script doesn't do all the work on its own, you'll need to install script manager (I can send you the apk to adb install if you need) and set the script to run "As root" and "At boot".

Now reboot your tab, go to settings/storage and enjoy swapped internal & external sdcards ;)
[Galaxy Tab 7.7 General] Edwrib:
Isn't /data/MEDIA /storage/sdcard1 ?
[Galaxy Tab 7.7 General] massdown:
I don't have any files in vold folder , what is that mean ?
[Galaxy Tab 7.7 General] Androguide.fr:
It's not, binding the whole /data folder works a lot better freeze-wise for me (with only /data/media I still get some freezes at times, and none or at least very rarely with /data)

Are you sure ? seems weird, try to reboot or change file explorer, there should be 2 files there (in /dev/block/vold)
[Galaxy Tab 7.7 General] Edwrib:
Whole /data to /sdcard? So the 'root' of you sdcard will be the root of data folder, not the media folder, the 'real sdcard'?

Never heard this way but ok.

my sim card not working with PA v.2.50 , I tried to install nexness PRO V2 after wipe cashe and dalvik cache, but it hangs on the (X) logo of the nexness pro on start. :(

before I tried the nexness rom I added the gapps folders in it as u mentioned before.

I just have some Questions...

1- can I install any rom ? 2- do I have to wipe only the cashe and dalvik cache before installing another rom ?
[Galaxy Tab 7.7 General] Androguide.fr:
Lol, man, you need to repartition (or at least to have a clean e2fsck for all 3 /system,/data and /cache partitions) every time you want to flash a Rom (or even any flashable thing basically).

Wiping /cache and dalvik is advised, and it shouldn't hurt if your e2fsck is clean.

As you own a p6800, I recommend you use PA v2.55, no issues reported atm, only good feedbacks. (link : http://www.mediafire.com/?cwv4z67n7ilf9rn // I don't take credits, i didn't build this one)
[Galaxy Tab 7.7 General] massdown:
My sim card didn't work with PA v.2.50 and nexness pro V2.

Hope it works with PA 2.55
[Galaxy Tab 7.7 General] massdown:
sim card not working anymore .... any help :(

I think i'll try to change sim card slot
[Galaxy Tab 7.7 General] Androguide.fr:
Simply flash a new baseband and use getRIL app from playstore to update your RIL, should fix your problem ;)

Don't order a sim slot or whatever^^

What does your settings/about device say about Baseband ?
[Galaxy Tab 7.7 General] massdown:
baseband version "Unknown"

sorry for being noob , how to flash a new baseband ??

I downloaded the GetRil app but it says that my device is not supported !!
[Galaxy Tab 7.7 General] Androguide.fr:
Download a stock ics for your region from sammobile and extract the modem.tar (or baseband or radio, can't remember the exact name inside the archive)

Then download and open mobile odin (free on xda, just search for it) and put the file you extracted in the "MODEM" slot of mobile odin, or use the "Open file..." to autodetect if it's a modem file to be sure you don't mess anything up
[Galaxy Tab 7.7 General] massdown:
let me know if I got it right...

1- I've a stock rom from samfirmware ,i'll extract and take the file "modem.bin"

2- flash the modem on mobile odin "phone button" ONLY

3- do a repartition again and flash the rom.
[Galaxy Tab 7.7 General] Androguide.fr:
Hmm I'd more do it like :

1- same

2- load the modem in the Modem partition slot (don't put anything else in any other slot) and flash it

3- Reboot to see if your tab still boots or needs a repartition

4a) The tab boots --> check if your sim is recognized again

4b) the tab doesn't boot --> you know what you have to do ^^

But yeah mainly it's like you said^^
[Galaxy Tab 7.7 General] massdown:
I was lucky , I just flashed the "modem.bin" and it's working :)

u saved me again :D THANK YOU
[Galaxy Tab 7.7 General] Androguide.fr:
Lol you're welcome, glad you got it sorted out :good:
[Galaxy Tab 7.7 General] dfkt_:
Thank you very much for this thread, Androguide. While my P6810 wasn't bricked, it suffered from weird sudden reboots when accessing System>Storage or System>Apps (full description of the problem here). Running your e2fsck lines over /system and /data partitions fixed the reboot problem for good. :)
[Galaxy Tab 7.7 General] mitoradeS:
Excellent thread and I believe that will help me... but what if I have access only to download mode (and not to recover mode)?
[Galaxy Tab 7.7 General] massdown:
connect your tab while on download mode and open odin on your pc

flash the pit file "P6800_ATO_PIT.pit" , then flash the "CWM 6.0.1.1" with odin too

now you can start your tab on recovery mode :good:

if u need any help or more details .. just ask , I've done that more than 10 times :D thanks to Androguide.fr :highfive:
[Galaxy Tab 7.7 General] Finovsk:

[Galaxy Tab 7.7 General] mitoradeS:
Wow, a big thank you is not enough, as a paper weight in my office has transformed into something more useful!!!

There are two more things though that I would like to ask:

1) Although the OP states that stock rom cannot be installed, has anyone did that successfuly?

2) I have some issues in transferring files to both external and internal sd card? Are these CM related or is it because of the repartition?
[Galaxy Tab 7.7 General] massdown:
1- i didn't try this

2- what app u use to transfer files ?

I'm using AndroXplorer and i can transfer files without any errors
[Galaxy Tab 7.7 General] mitoradeS:
Windows 7, with the tab connected as media device
[Galaxy Tab 7.7 General] massdown:
yes I have same issues while transfer files to external memory Only , so I have to remove it and connect it with a micro reader
[Galaxy Tab 7.7 General] edan1979:
i have issue to transfer as well but its only when the device screen turn off... when i make it stay awake... dont have the problem...

Hello.. can someone please help...

I had ICS then used this thread to go to PA255

http://xdaforums.com/showthread.php?t=2032473

So I though I messed it up, because it never rebooted..

Finally it did and I decided to goback to ICS,,

that's when things got borked..

Now all i get is the

"Samsung Galaxy Tab

7.7"

screen comes on for a while...30 seconds or so..... then goes dark..

then comes back on....over and over again.

It wont even shut off.

I can still get into D/L and recovery...., so..

I went to page one of this thread here & did the steps

- Flash the latest cwm with ODIN

- Do NOT wipe anything ***** ***** except I mis-read this and DID wipe*****

- Flash the custom rom of your choice

- Reboot recovery

- Wipe what you need to wipe

- Re-flash the custom rom

- flash the gapps or whatever

- Reboot, done.

Now Im stuck at the Samsung Galaxy Tab 7.7 coming and going.

that's the extent of my experience is with Odin and Recovery only..

Please help.. as my tab is still cycling the GST7.7 over and over again.

thanks alot for all your help.

PS.. I can still get to Download and Recovery Modes..

Is there no hope for my brick???

thanks again

one more item that may have some importance

Now when I hook the USB to the computer (while the SGT7.7 is cycling)..

then hold the power button to turn it off......

I get this weird smaller all white battery charging icon.. not the typical bigger blue one
[Galaxy Tab 7.7 General] edan1979:
flash cwm and then wipe your data/cache/dalvik in recovery...
[Galaxy Tab 7.7 General] jimmbomb:
Thanks Edan... yes.. I have done that... at least 3 or 4 times now already...

All those functions give me a success .

She just won't reboot fully after that.. stumped
[Galaxy Tab 7.7 General] edan1979:
ok... you need to do the long way... flash honeycomb...
[Galaxy Tab 7.7 General] Kralik:
Quick question (I hope...)

What are the symptoms of superbrick? As I understand it, there can be corruption of your system/data partitions. Is it possible to have a seemingly working system with damaged eMMC? I ask because I recently flashed to the i815 LP10 and experienced serious instability (every app FCed at once when installing updates from Google Play, Tab took about five tries to reboot without hanging on splash screen).

I ran a eMMC check program and it didn't report any errors... but if there was a good way to know for sure I would appreciate it.
[Galaxy Tab 7.7 General] edan1979:
yes you can check using the same guide on the first page... but just use the 3rd step where e2fsck command is use on both of your system and data partition.
[Galaxy Tab 7.7 General] jimmbomb:
thanks Edan1979 (my first Harley was a 79 low rider)

..

I've done that twice with 2 different versions that i got from sammobile...

same result...

She just won't reboot no further than the

Samsub Galaxy Tab 7.7 screen.. then it cycles off and on..

I can't even get to the splash screen..

right now. my last Odin flash was stock Samsung HC.....

please continue to suggest stuff..

I have a useless tab right now.

thanks again
[Galaxy Tab 7.7 General] jimmbomb:
you know... it just dawned on me that I might be flashing the stock HC with Odin wrong.....

I put the zip in the PDA file slkt and tick only the PDA box... right?

Also the only other box that is ticked.. is the auto- reboot... correct?

that a how I have been doing it... and it just will not get passed the Samsung Galaxy Tab 7.7 screen...

maybe

I should flash all or any other choices..

ie: PIT,BOOTLOADER,PHONE,CSC?

thanks for any and all help... I'm still stuck.. no splash.. no tab
[Galaxy Tab 7.7 General] Androguide.fr:
Just forget about ODIN man, you'll never be able to use it with your 7.7 anymore.

Go to the development forum, pick a rom you want to use (if you want to stay stock then pick a custom rom based on stock - but really, touchwiz sucks), then follow the guide in the OP carefully, and when you got your repartitioning done, flash that rom through recovery - again, this is explained in the tut - (use cwm or twrp, never ever use the stock recovery) and you'll be good to go, with a revived tab ;)
[Galaxy Tab 7.7 General] Kralik:
Thanks for the tip. I got (0.3% non-contiguous) on data and something like 1% on system, so I'm guessing my woes were completely unrelated. I've never wiped with stock recovery before, though I did with TWRP.
[Galaxy Tab 7.7 General] jimmbomb:
well.. thanks guys for the answers..

This once nice Tab just isnt responding..

I have CWM 6.0.2.3 on my ext SD and choose it in recovery..

Now Im on CWM 6023 and install zip from ext sd

CM_10.1_20130105_Nightly_p6800,zip

everything goes smooth this far.. everything has a sucess notice..

then I go and wipe cache partition/delvic cache

then wipe date fr///

then go back and install the CM10.1 again.

then do the wipes again...

(sucess again) and then finally reboot..

and stuck at the Samsung Galaxy Tab 7.7 screen.... for about 20 seconds... then goes dark...

then back again for another 20-30 seconds.... dark....

over and over again....

This wont even shut down....

I can force a shut down by plugging into a power charge cable and holding down the power button till a weird battery icon comes on,

Im close guys, I can feel it.. c'mon.. we're almost there.. the Tab is still doorstop....

stay with me... thank you all...

[Galaxy Tab 7.7 General] edan1979:
that why i ask you to manually check the partition of the /system and /data

i believe there's a corruption somewhere... i only see that error shown on your other thread when the partition is corrupted.
[Galaxy Tab 7.7 General] jimmbomb:
yes thanks edan...

I was wondering about 'androguide.fr's' statement a few replies ago..

in part "" and when you got your repartitioning done, flash that rom through recovery -""

Now I thought that meant to wipe 'cache partitions'..

So I did do that..

BUT you said to

" i ask you to manually check the partition of the /system and /data"

Now admitedtly, I did miss that in your earlier post..

Can you please explain that & how to go about doing that move?

Remember, I can only get into recovery and D/L..

So I you can guide me thru that manuever... then we're alomst home!!

Cool... please help me a bit more....

We are--this-close!!

thanks again....

*** Ok. here is step 3 in the first post on page 1..

"3) Meet another good friend : e2fsck

Now we've done our fresh and clean partitions, you must be thinking we're done, but we're not ^^

In fact the two partitions we made are using ext2 filesystem, but the /system partition's filesystem should be ext4 (like it was at the beginning).

There are two ways of converting an ext2 filesystem to ext4 that I know of :

- Simply formatting /system in cwm recovery will convert the filesystem to ext4. To do this, just head to "mounts & storages" and select "format /system".

If it gets stuck while formatting, reboot your recovery by pressing the power+volume-up buttons for about 15 seconds, and head to the next part, you have to do something before you can try to format it again.""

So.. all I do is that step 3 only?

That's it??

Sounds simple enough.... please confirm that this is my next step and that I dont have to do the prior steps 1 & 2... as they are very french to me and I'd probally need a bit of hand-holding thru those...

thanks to all for your help.....

So.. again... is this my next move?? Step 3 ??

boot to CWM...... mounts & storage....select format/system??

thanks alot!
[Galaxy Tab 7.7 General] edan1979:
yup.. only do part 3 from this section

3) Meet another good friend : e2fsck

Now we are going to use e2fsck to check our new partitions for errors, but not only, it also fixes some erros and it will even for example create lost & found in /data

1. you need to be in recovery mode aka CWM.

2. must have adb in your pc and you know how to enter adb shell (which i believe you do)

3. just runt he checkup using the guide.
[Galaxy Tab 7.7 General] jimmbomb:
Thank you edan 1979 but,,, sadly.. I do not have adb on my pc and I do not know how to enter adb shell.....

sh*t...

can you please point me to a thread on how to do this... or shoot me a PM....

Im afraid some one 2 1 help is going to be neeeded for this....

dammn almost there though.... it's been a week since Ive got to use this tab.. and I am sorely missing it bad...

thanks.......up-date..

ive downloaded and installed

adt-bundle-windows-64

and ran Eclipse.

And now I have found the platform tools and adb.exe..

I guess Im ready for the next steps.....??

[Eee Pad Transformer Q&A, Help & Troubleshooting] iLearner:
Hi all!

Was about to purchase a Nexus 7 when I saw a huge discount on the Asus TF101 and decided to take it. How I have a it in front of me proudly informing it has the firmware revision IML74K.WW_epad-9.2.1.27-20120615. BTW, the s/n starts with B50 if it matters.

And now what? Wait for the official JB or root it right now? I usually root all my devices at least to have nandroid + TiBu, even if I don't plan to install any alternative FW.

The problem is it's an ICS 4.0.3 with the problem to enter into recovery mode and I have only a Mac computer, no Windows and no Linux machines around. I read the threads and see every time the Windows tools, nothing for Mac. No root from SD card neither.

Any advice how to root using the Transformer itself or my Mac? And any advice regarding best JB ROM or at least best kernel for stock 4.0.3 ROM with exFAT support? I don't use NTFS because my Macs can't write on and old FAT16 has the famous 4 Gb limit, not good for the movies.

Many thanks in advance.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Shmi117:
You could try and install Windows on your Mac to essentially have a dual boot of both OS's. Or you could use something like VMWare (I think that's what it is but I'm like 5% sure) which allows you to run windows without necessarily installing it. Anyway, I suggest, if you can, to go ahead and root your device and install a JB ROM like EOS or CM10 or something.
[Eee Pad Transformer Q&A, Help & Troubleshooting] WCL1990:
If it's not possible to do Android modifications on a Macintosh it looks like your only option would be to setup a dual boot with Linux to do your Android Rooting and ROM flashing since I would imagine you would want to avoid having to use Windows for this It would be better to avoid virtual machines to do device modifications and just stick to the dual boot option since support for USB devices is iffy in virtual machines.
