Do you think that on P6810 I can do Bluetooth tethering using my Android smartphone?

I will try as soon as I come back to home tonight ... hoping to see soon wifi working ...

thanks locerra!

EDIT: I thought to be in the CM9 dev thread ... anyway: installed CM9, it's super fast, but I wasn't able to get bluetooth tethering, wifi doesn't work ... so I'm going back to HC :(

[Galaxy Tab 7.7 Android Development] Gilbot:
After a bit of searching I figured out why the SCH-i815 CWM will not stick on Stock ROMS after the FD01 update.

The FD01 update places the file "recovery-from.boot.p" in the /system folder which overwrites custom recoveries upon boot. To stop this from occurring, you will need a root-enabled file explorer. Navigate to /system and rename the "recovery-from.boot.p" file to "recovery-from.boot.p.bak" or, alternatively, you can delete the "recovery-from.boot.p" file (renaming it is better in case something goes wrong). You can then flash a custom recovery and it will stick.

EDIT: Be careful, its possible you can run into problems if you use lockscreen security, I suggest making sure your tab is using an unsecure lockscreen: the "swipe screen to unlock" lockscreen before flashing CWM in Odin mode. After flashing CWM through Odin, I suggest making sure your tab does not boot into the stock rom and immediately make a nandroid backup.
[Galaxy Tab 7.7 Android Development] platodd:
Installed and wotking fine. It would be great to have something to flash now, lol.
[Galaxy Tab 7.7 Android Development] rayjr13:
Not sure what happened. I flashed CWM after doing: "recovery-from.boot.p" and rename it to "recovery-from.boot.p.bak" then power down your tab.

Flashed CWM using PC Odin pda with auto reboot, f. reset time. Got PASS.

CWM loaded up but rebooting to stock resulting in a screen stating to "enter your password".

I used adb to restore the file by removing the .bak from the file name. Rebooting into recovery shows Android systen recovery <3e>

The message at the bottom says:

E:failed to mount /data (invalid argument)

#manual mode#

any suggestions on getting booted back to stock ROM. I thought tar from above only flashed the recovery partition any reason why it wouldn't boot back into stock? Or any idea what to enter for the password?

thanks
[Galaxy Tab 7.7 Android Development] Gilbot:
I'm not sure why it would ask for a password. Are you basically getting a passworded lock screen when booting into the stock rom? Maybe the tab needs to have an unsecure lockscreen before attempting this.

At this point I would use electron73's FD01 files to get you back into the stock rom and restore stock recovery (you will lose root but should still keep all your apps and settings, etc..) Please take your time and know that based on the information I know this should work, but know you're taking a risk. Please make sure you are only performing these procedures over your stock rooted rom.

-First load up an external microSD card with the "SCH-I815_FA02c_To_FD01.1.zip" file electron73 hosted here : http://www.mywo.org:88/XDA/sch-i815/index.php. Hopefully you can do this on a PC or push it if you're able to use ADB. Don't flash this file yet, just have it on the external SD card and have the card in your tab.

Make sure your external microSD card is in the tab with the "SCH-I815_FA02c_To_FD01.1.zip" file before you flash with Odin.

-Boot into download mode, load up Odin and Flash CWM again, without auto reboot checked. Once you get a green PASS with Odin, disconnect the tab and hold power until it powers down, but be ready to immediately hold power and volume up to boot into CWM once the tab turns off.

Do not

let it boot into the stock rom.

-At this point you should be booted in CWM. Using CWM, flash the "SCH-I815_FA02c_To_FD01.1.zip" on the external card. It will take a few minutes. This will basically re-flash the FD01 update onto your tab except for the baseband (radio), including the stock e3 recovery. The baseband is not needed at this point if you did the FD01 OTA update anyways.

-Reboot

You should now have stock 3e recovery and should be able to boot into the stock rom. You will not have root access. You can re-root your tab to gain root again.
[Galaxy Tab 7.7 Android Development] rayjr13:
Even in the CWM recovery I get consistent "Can't mount /data"

---------- Post added at 12:27 AM ---------- Previous post was at 12:23 AM ----------

My goal was to do just that but CWM says E: Can't mount /sdcard/

will try loading CWM again not sure what the deal with the CWM and me is right now.

thanks for responding

btw i did have a pattern lock set on my tab. The "lockscreen" was just an all black screen with an android guy wireframe image and and small dialogue box in the center and a android keyboard below. Any password i put in resulted is "sorry, try again"
[Galaxy Tab 7.7 Android Development] rayjr13:
installing SCH-I815_FA02c_To_FD01.1.zip in CWM:

error status 7

failed to stat "/system/app/Gmail.odex": No such file or directory

script aborted:assert failed: apply_patch_check("/system/app/Gmail.odex".

I asssume its because I had market updates of some system apps like gmail integrated to ROM by TiBu. so technically its not still stock fa02c updated to fd01... hitting the hay for now.
[Galaxy Tab 7.7 Android Development] Gilbot:
I think its expecting to find certain things as stock? Not sure man.

I used this exact process on an old stock nandroid and it worked. I never really removed certain apps and changed much within /system. Seeing as how you can boot into CWM and flash the SCH-I815_FA02c_To_FD01.1.zip file, you can more than likely factory reset within, ****ty thing is you're going to lose app data. Sdcard files will remain in tact at least.

or you can restore a nandroid. If you don't have a nandroid backup, you can download the stock nandroid supplied here: http://multiupload.biz/hnk4gmktgmhz/GTab7.7 sch-i815 stock cwm_MultiUpload.biz.7z.html

I would flash that nandroid as a last resort.

I wish someone here with Linux/UNIX and some skills could create an ODIN flashable tar file of a stock CWM image, it sucks having no firmware to fall back on.
[Galaxy Tab 7.7 Android Development] rayjr13:
Most definitely agree with all the above. I'm not really stressing losing my data and such. Benefit of TiBu/dropbox. If I can get back running I can always startover.

Gotta pay to play lol. Anyway I did plan to just stock NANDROID that file. But my REAL QUESTION is why doesn't (or does yours and mine doesn't) CWM 5.5.0.4. successfully mount /data or /sdcard all other partitions claim to mount correctly: efs, cache, system, preload, emmc.

locerra, maybe you can clarify if this is part of the instability or known bugs? If it truly cannot mount data and sdcard are backups and restores completely possible?

Like i said maybe something is borked with mine. md5 on the CWM-20120710-i815.tar was correct and odin3 v 3.07 gave the Green light.

If the file is damage, why don't you try to re-download it?
[Galaxy Tab 7.7 Android Development] rayjr13:
Not sure how file damaged by downloading passes hash check? Am I missing something?
[Galaxy Tab 7.7 Android Development] locerra:
Everything should work, nothing is really unstable in this build, and everything should work (except mounting via USB, which isn't really supported by CWM anymore).
[Galaxy Tab 7.7 Android Development] rayjr13:
good to know. The major hang up for me is that everytime i try to do any backup or restore operation the CWM recovery cannot mount /data

The CWM.tar passed hash so all I'm left with is thinking it was not removing the password.
[Galaxy Tab 7.7 Android Development] locerra:
Try formatting it in recovery? (You will loose any settings, FYI)
[Galaxy Tab 7.7 Android Development] rayjr13:
tried wont format data because it cant mount data...just tried to mount it in adb shell but got invalid argument

#mount dtaa

mounting dev/block/mmcblk0p10 on /data failed: invalid argument

all CWM operations that involve data fail when attempting to manipulate /dataL wipe, format backup or restore.

Next thought is factory reset in stock recovery
[Galaxy Tab 7.7 Android Development] locerra:
You have an I815? If you do, what does

$ adb shell ls /dev/block

(Doesn't matter where you do this, it should be the same regardless of rom/recovery)
[Galaxy Tab 7.7 Android Development] rayjr13:
I'm back up and restored from TiBu using factory wipe in stock recovery. But let me check that. I did a /mount befoer i started and copied it to Gilbots info thread.

Yes I have i815 here is what i get in shell:

[Galaxy Tab 7.7 Android Development] locerra:
Ok, try this while you device is in recovery:

$ adb shell mke2fs -T ext4 /dev/block/mmcblk0p10

Follow that with a wipe/factory reset, hopefully that will fix you issue with it not wanting to mount.

This will delete everything from the data partition, including everything from the virtual internal sdcard, be warned.

[Galaxy Tab 7.7 Android Development] HapaBiH:
I have a big problem on my p6800 after instaling ICS for the first time. I got the Encryption Unsuccessful message and that is all. I found out that the problem is that sdcard can't mount and the system thinks that it is encrypted. My tab is probably lost and I'm trying quide for partitioning ext sdcard for system to use as a internal memory. Problem is that the CWM after selecting Partition SD does not partition external sd but tries to partition internal sd. Is it even possible to boot from sd card or to partition from cwm on this device?

EDIT: Fixed it, stock recovery did the trick, tab now works again :)

CWM6 Getting Stuck

Hi

I am seeing that CWM6 is getting stuck when doing a backup. I tried backing up to internal memory and the sd card with the same result. It seems to get stuck trying to backup the file "full_model.bin". It has happened twice. I was hoping that CWM6 would fix the issue I was having with 5.5.0.4. In that version, CWM would get stuck on the file "uncompress". I am trying to backup the stock ICS rom. Shouldn't be a problem right?
[Galaxy Tab 7.7 Android Development] locerra:
Well there a bug with CWM6 with nandroid that causes more or less what you are experiencing -- however, it wasn't in older versions of CWM (CWM6 has a completely new nandroid, backups are tiny in comparison to old backups). This was fixed while I was away camping, I'm hoping to get a new build up with the fix, as well as a few other small changes in the next couple of days.
[Galaxy Tab 7.7 Android Development] markadan:
Thank you for the confirmation of the issue. Looking forward to the next version.
[Galaxy Tab 7.7 Android Development] zorbakun:
Can your new recovery be based on custom Kernels instead of official ICS kernel? Like ezynow's new custom kernel? it has the MMC_CAP_ERASE disabled in it, so possibly a bug free kernel at last. Thanks
[Galaxy Tab 7.7 Android Development] locerra:
All my recoveries have been based on the CM9 kernel, which have always had MMC_CAP_ERASE disabled. Also I've configured it do that software doesn't even try to do a secure wipe either, so this CWM should be double insured against the brick bug.

so external sd is.....? :D

can i restore a nandroid backup from 5.5.0.4 with the 6.0.1.0 version?

i tried some different 5.5.0.4 cwm versions and the one from this thread adds some additional files, with other 5.5.0.4 cwm versions i can't restore them.

5.5.0.4 backup from here :

e.g.

system.ext4.tar > 0kb

system.ext4.tar.a > 732.485 kb

another cwm backup only produces

system.ext4.tar > 732.485 kb (without the 0kb file)

We will not get official support from CM?
[Galaxy Tab 7.7 Android Development] locerra:
We might, I keep bothering the people who must ok it, so we'll see. What I meant is that the only way that I know of making a touch recovery is to use Koush's Recovery Builder -- which runs on the CM build cluster. Unfortunately, for reasons that I have been unable to figure out, our tablet doesn't like Android's boot magic, so we can't use the standard build system (which Koush's Recovery Builder uses). I have a hunch that the Builder will use the device configuration I have made for CM if it lived on the build cluster, which will only happen once my port is granted official status.
[Galaxy Tab 7.7 Android Development] platodd:
How did you get back to stock recovery????
[Galaxy Tab 7.7 Android Development] rayjr13:
I never loaded another ROM so I reverted back the .bak file I made on i815 /system folder

Locate the file "recovery-from.boot.p" and rename it to "recovery-from.boot.p.bak
