For the moment I've gone back to CM7, because it's the most stable and functional of all the ROM's I've tried. Earlier experiments to install it failed, and I assumed that was because it hadn't been modified to run on an sdcard as if it was internal storage. I've been reading up on this topic, and the impression I got was that a ROM can be made to run by modifying vold.fstab. I had a look at the original vold.fstab again, and it looks like this:

# internal sdcard
dev_mount emmc /mnt/sdcard/external_sd 1 /devices/platform/s3c-sdhci.0/mmc_host/mmc0

# external sdcard
dev_mount sdcard /mnt/sdcard auto /devices/platform/s3c-sdhci.2/mmc_host/mmc1 /devices/platform/s3c-sdhci.2/mmc_host/mmc2

If I understand correctly, this means that external storage is mounted as internal, and internal as external, so both storages are already swapped! This seemed familiar, I recall this was done by Samsung for one reason or another, and to restore common sense CM decided to undo the swap in build.prop, that's why it has the following setting:

persist.sys.vold.switchexternal=1

This swap/unswap business works, but because I actually wanted to swap storage locations, I decided not to modify vold.fstab as it was correct as it was. Instead I just opened the ZIP with the CM7 ROM, and modified build.prop in the ZIP by changing the setting to:

persist.sys.vold.switchexternal=0

This way I don't have to change anything during or after installation. I had stumbled upon this with CM10, but I assumed the reason I could install CM10 while CM7 failed was because jt1134 did some magic which was activated by putting a file called activate_data_on_sdcard on the sdcard.

I changed the setting in build.prop and saved the modified ZIP. First I placed the ZIP and GB gapps on the sdcard, I flashed the Overcome kernel, rebooted into CWM, and finally I installed the ZIP and gapps. I rebooted, and somewhat to my surprise it booted into CM7!

If the internal storage is broken, I think an unmodified ROM will install straight away if you've removed it before installation. This doesn't work in my particular case however, because although the internal storage is broken, as I haven't removed it, it's present and detected. That's why I have to swap the storage locations.

And all of this assumes you have partitioned the external sdcard to function as the internal storage location, of course.

Post the modified zip? You did not removed the chip inside the tab at all?
[Galaxy Tab General] ableeker:
The Tab hasn't been modified at all, the internal storage chip hasn't been touched.

I use a build I've compiled myself, but you can download the latest official unofficial build here, created by the man who ported it to the Tab himself: Technomancer.

Open the ZIP, (best not to unpack it, just open it), edit /system/build.prop, change switchexternal to 0, save build.prop, update the ZIP, and put the modified ZIP on the sdcard.

Actually, you can even install the unmodified file, at least it works for me. If you do that, after it has rebooted into CM7 the first time, use a root file editor to change switchexternal to 0 in /system/build.prop, and reboot again. Modifying the ZIP before you install it just saves a reboot and allows you to install the ZIP without having to modify build.prop every time you reinstall it.
[Galaxy Tab General] vampir4997:
I have a copy of 9.1.0,can you specify what line tue edit is in im having trouble finding it. You link doesnt work for cm7.
[Galaxy Tab General] ableeker:
When you open the ZIP in for instance 7-zip, you see two folders, one of which is system. Open folder system, and you'll see more folders, and file build.prop. Open that, and look for the line that reads

persist.sys.vold.switchexternal=1

Change it to

persist.sys.vold.switchexternal=0

The file can be downloaded at the following address: http://gtab7.nexus-lab.com/cm7sgt/cm-7-20120805-UNOFFICIAL-galaxytab.zip. I thinks that's the same address, maybe the site is a bit temperamental.

What u sure !:eek:

i tear up my device the internal was glued with super glue ! i used knife an exacto knife and small screwdriver made some scratch on the board cut my hand few times:crying: but when i cleared the internal drive went to download mode felt good i hope i'm doing right

anyway i'm still noob on this i bought 16 gig class10

fcc model : A3LGTP1000

lMEl 353954****** (middle east version)

sorry guys i couldn't keep up whats CM7~10 and how to ABD command

what rom should i pick for GB ICS JB

my original rom was froyo 2.2
[Galaxy Tab General] ableeker:
That's probably the best way to bring the Tab back to life after the internal storage has stopped working. I believe that if you're willing, and able to hack the hardware, this is the better solution. Sometimes for instance my Tab doesn't boot, maybe because the internal storage sometimes is detected and it wants to boot from it and of course is unable to. In these cases I reboot until it starts, but this may take quite a few tries. If the internal storage is actually physically missing, you won't have this hassle.

As a matter of fact I'm not even sure CM10, and CM7 can be installed unmodified on a sdcard when internal storage is broken on all Tabs. It works on mine, I've have been running CM10 and CM7 on it, but I have only the one, and mine may be a special case, it may fail on other Tabs.

Actually, I still am mystified by the way the Tab boots. If the internal storage is missing, where does it boot from? External storage? Is that even possible, I didn't have to make the sdcard bootable? A third kind of storage? Are CM7 and 10 ROM's prepared for installation on broken internal storage? I have read about other devices with damaged internal storage where people had to modify the kernel or at least vold.fstab of a ROM before it would start up again. That's not needed with CM7 and 10 on my Tab at least, but that may be because the awesome CM wizards created the ROM's this way? Someone did an incredible job anyhow!

Anyway, CM 7.2, CM 9, CM 10, and CM 10.1 are modified versions of the original Android source created by Google. CM, Cyanogen Mod, has been made to be portable, and even has been ported to devices that won't ever see official versions, like the Galaxy Tab 7. CM 7.2 is created from the Gingerbread source, CM 9 is ICS code, CM 10 is Jelly Bean, and CM 10.1 is Jelly Bean 4.2. CM7 is most stable and just about everything works. CM9, and 10 are more modern and they look very nice indeed, but they seem less stable. CM 10.1 isn't official yet, and drains the battery faster because it seems to have trouble getting to deep sleep.
[Galaxy Tab General] priyana:
There are 2 internal storage in P1000

OneNAND, SLC, 512MB which is faster,

and MoviNAND, MLC, 8/16GB (32GB?) which is slower.

I believe the bootloader, modem, and all are in OneNAND, which is still good. It is your MoviNAND that is broken. and this is the one glued to the board.

I think the /data and /cache is in MoviNAND.

Remember in CM10 there was a new MTD layout that at one point the /data was moved to OneNAND to get more speed but you can't install too many stuff in it?

Eventually it was only /data/data that was put in OneNAND in final layout.
[Galaxy Tab General] galaxytap:
tnx guys 4 responding

so I can't do this tut if my MoviNAND is broken ?

if I can what mod i should use original or or cm cuz i want it to support Arabic language

i made the partitions all primary 500mb ex4 500mb ex4 13gb fat32

but icant find the fat32 it must be formatted windows cant read ex4 do u think i must start with fat32 then the other EX4s ?

all i hav to do now is download a rom and make some adjustment to it

switch to download mode then run it on odin

any advice pls if there is any links
[Galaxy Tab General] ong14:
First of all, CM10 archive need to be modified on *nix or *nux. If you repacked it under Windows, it will mess up.

I put CM10 on my SCH-I800 with this method;

0. Prepare partition on uSD as

0.1 First partition ext4 512MB for /cache

0.2 Second partition ext4 2GB for /data

0.3 Third partition FAT32 the rest as /sdcard

I did this with Sandisk 8GB Class4, CM10 runs very smooth.

1. Prepare CM10 archive (I did this with Ubuntu on VMWare)

1.1 Extract updater.sh from original CM10 archive

1.2 Replace the line with "SD_PART='/dev/block/mmcblk*p1'" to "SD_PART='/dev/block/mmcblk0p3'"

1.3 Save updater.sh and move it back to original CM10 archive

2. Flash my TAB with "boot.img" extract from CM10 archive using Heimdall. (This can be done under Windows, just choose Kernel (zImage))

3. Enter Recovery mode with these steps

3.1 Power off

3.1 Holding Vol+ and Press Power button

4. Wipe data and Factory reset

5. Connect USB cable

6. From recovery menu choose "Install from sideload"

7. On your Windows command promt, run this command

adb sideload [CM10 modified.zip]

8. Repeat step 7 with gapps

Hope this will help.
[Galaxy Tab General] vampir4997:
Thanks,ill look again but i didnt see it
[Galaxy Tab General] galaxytap:
searched for cm10 found this ver

adjust "SD_PART='/dev/block/mmcblk0p3'"

when i browse for the frameware in heimdall it give me this message ''Tar header contained invalid file size''

how to to flash with boot.img ?

since i remove the internal memory i cant go to recovery mode and i cant see the battery charge it only show battery with freezing process

i only can enter the download mode
[Galaxy Tab General] ableeker:
Thanks for the info, priyana, that makes a lot of sense! One of the symptoms of a broken internal storage is the error in recovery mode saying cache can't be mounted, so I'm fairly confident /cache is housed in MoviNAND indeed.

And yes, I do remember the move quite well!

galaxytap, this means that you CAN do the tutorial because even though MoviNAND is broken and has possibly been removed, OneNAND is still working.

I'm not sure about the partitioning, but I have no such problems and the first partition on my sdcard is indeed FAT32.

If you've removed the chip, I think you can install any ROM. CM works for me, and I can see a language that looks rather Arabic to me, but not being able to read or write Arabic I have no idea if it will work.

That ROM is pretty old, better get a nightly from get.cm/?device=p1.

vampir4997, I think that setting is only available in CM ROMs, Overcome for instance doesn't have it. You mention CM9, puzzling really, because CM7, 9, 10 and 10.1 all have the setting, I've just checked... If it isn't available you can take a look at vold.fstab, and check if the storages have been switched there. If so you don't have to do anything. If it hasn't been switched, you'll have to modify vold.fstab to switch them.

ong14, that looks good to me.
[Galaxy Tab General] galaxytap:
tnx for the site i got the last cm10 and adjust the code in 3 spot :

# Check if we're in CDMA or GSM mode

# GSM mode

# Check if this is a CDMA device with no eMMC

u think i hav to change it all or just the first one?

about the partitions i use mini tool partition wizard i can't start with fat32 it must has the rest of sd maybe after u flash it

it appear in windows ? and wat is best partition for 16 gig sd ?

what's the next step how to flash. hope it didn't require recovery mode cuz i only got download mode!!

i cant open the rom in heimdal the same message ''Tar header contained invalid file size''

sorry guys for may many questions
[Galaxy Tab General] ong14:
Do as ChrisCTX said, but you can change all of them.

To get a recovery mode, try flashing CWM 5.0.2.7 via download mode first.

You can get Heimhall for Windows and CWM5.0.2.7 if you search on this community.

Just flash only [zImage] and [recovery.bin] with Heimhall, then you can enter recovery mode.

I also use Mini Tool Partition Wizard, because it is a lot easier for me than Gparted.

i fixed the CAMERA Problem by using this simple method.

i forget which root browser i downloaded to make this work.

i think i may have tried numerous ones. ASTRO/rootbrowser lite/ESfile explorer,...etc...i think it might've worked with "root browser lite"which is found in the GOOGLE PLAY store for free.

make sure you allow the new "SDCARDFolder/external folder that you created to have all PERMISSIONS. to do this.

*hold your finger on the folder of "SDCARD" (its the only black folder if youre using rootbrowserlite), and hit "permissions" then check every box under the fields of "READ/WRITE/EXECUTE" once thats done, go into SDCARD & create a new folder called DCIM, then go into the new DCIM folder and create another folder called "Camera"

it should look like this /SDCARD/DCIM/camera

then restart the phone and try entering "gallery" to see your pictures or try taking a picture. it should work fine.

sometimes it crashes on me, unsure why, maybe thats just the rom. if it says not responding "wait or exit/cancel" click on wait. its cause of the microsdcard not being fast enough. thats all. if you click wait. your application will load fine.

make sure you get a buy a fast microsdcard of CLASS 10 or better if they make one. i tried a class 4, and it was super slow. it wouldnt even load the GPS. class 10 loads fine.

i have the galaxy tab p1000 gsm. i use it as a smartphone with a simple mobile simcard. i get texts/calls/data with no issues

im on CM 9.1.0 stable. this method works with any CM or other rom. i tried it. cm10 is better, but crashes way too much. so if i were you, i would definitely go to cm9 on this Phablet until they make a CM10 Stable version. i dont even hook it up to the computer to install the rom or do ADB shell. it installs fine just by entering recovery and installing the zip.

after removing the internal mem - got battery sensor problems

Hi,

After i removed the internal memory and reassembling, i started to get battery temperature sensor warnings on the screen while charging

(see pic and description here: http://xdaforums.com/showthread.php?t=2133928)

Has anyone got this too ? any ideas how to fix it ? maybe i just didn't reassemble it correctly and the batt sensor wasn't placed well ?

Thanks

[Galaxy Tab General] thedrs:
Yeeeeha ! it works !

Success story:

What: Managed to install CM10 latest official nightly + gapps on a P1000 with malfunctioning internal memory.

On: Galaxy Tab 7 P1000 GSM version (Israel - had originally froyo 2.2)

Details:

1. Did surgery procedure and removed the internal mem chip physically

2. Partitioned a fast class 10 sandisk 16GB flash microsd to 7.6GB Fat32, 3.5GB Ext4, 3.5GB Ext4 (in that order - Fat32 first - using the windows tool proposed) [ the numbers are not exact - i just did 1/2 + 1/4 + 1/4 of what i had available ]

3. downloaded and copied to the Fat32 paritition:

a. latest official CM10 (nightly) for p1 (p1000) at : http://get.cm/?device=p1&type=nightly [i used cm-10-20130210-NIGHTLY-p1.zip ] [this is 4.1.2]

b. latest official gapps at : http://goo.im/gapps/ [ i used the last one for JB 4.1.2 which was: gapps-jb-20121011-signed.zip [newer JB versions are for 4.2.X and up]

2. booted into CWM - power on + volume up

3. from CWM: installed from sd card CM10 zip

4. from CWM: installed from sd card gapps zip

5. from CWM: reset factory settings

6. boot

7. went through the wizard initial setup steps

All seems to work (downloaded apps from store), except for a message in the camera app "no external storage available" - not sure but i think this is the external sd issue that was mentioned previously in this thread... i will try the solution proposed there and update later.

In settings->storage i see:

internal storage: 3.65GB

SD Card: 7.39GB

Note: I did not edit any zip file, i just installed them as they are (i saw the CM10 had partition 1 as its sdcard in the fstab and i knew my fat32 was the first partition so no reason to change anything...)

Thanks a million !

UPDATE [9-mar-13]: cm10 gave me problems after some time left alone the tab wouldn't "wake up" from sleep (it would flash the button lights but wouldn't open the screen) - i was annoyed by this so i tried CM9 but then the wifi stopped working .... still trying to find a good solution for my tab ... sorry.
[Galaxy Tab General] vampir4997:
Could you please post a pic of your computer screen when your partitioning the sd? I have my tab running but cannot get clockwork to see anything. Im pretty sure its because i cannot get the partitions correct. Thank you
[Galaxy Tab General] thedrs:
After flashing to cm10 this id no longer is a problem

when the tablet is on and the OS is running

- charging is normal.

But when the tablet is off this still happens.

I assume i have somehow flashed previously a bad version to some special boot partition and that is causing the problems.

I had already had cm9 installed when i did the hardware mod i just had alot of force closes and could not do anything with the tab. Im assuming you have no rom installed. In that case i would try to get a rom installed via odin or hemdall. After that make sure you have at least an ext and a fat partition on your sd.

I haven't visited back here in a while to see what changes have been made but I see some official CM10 images for the p1c now but as it sits you cant or at least I cant use the automatic updater because of either the way I have my partition layout on the SD or because recovery cannot mount the non-standard sd/external sd to flash the ROMs.. I'm not quite sure which is at fault. Can anyone answer this dilemma?
[Galaxy Tab General] Kemotar:
Hi, noobie here!

I've got a Galaxy Tab which seems to be having issues with the SD card, but I'm not sure the problem I'm having is the one described here. the symptoms I'm experiencing is that everything seems to work OK... installing apps, flashing roms etc EXCEPT when I boot up the Tab, the apps say there's no SD card. In other words, when I open the camera, it says "Insert Memory card to use camera", and other apps give similar messages when they need to access the SD card. Some apps work if I insert an external card, but others don't.

I'd be open to trying the repair in this thread, but just not sure if that's what I need!

Thanks!
[Galaxy Tab General] vampir4997:
You dont need the repair described in the op. It is for tabs that the internal memory gets locked and you cannot remove data from it. You should try a different sd card or maybe the rom your running has a bug.
[Galaxy Tab General] Kemotar:
Sorry should have made it more clear... it is actually the internal SD that seems to have the problem. I can put in an external SD and some apps will then work, but others won't (I assume because they are configured to only use the internal SD.) I'm guessing that somehow this has to do with partitioning. From what I've picked up, I have a hazy notion that the internal SD is supposed to be partitioned with one partition being used for the system and another being used for the user files. It seems that the system files are fine... apps install and the OS works, but there is no space for user files.

So, if the above guesses are correct, it would seem that I somehow need to fix the partitioning or something. I've played with the partition feature in CWM but so far no luck. Of course I had no idea what I was doing so that's not too surprising!

If anyone can correct my guesses or give me insight into how to fix this it would be great!
[Galaxy Tab General] vampir4997:
http://xdaforums.com/showthread.php?t=1275031

This thread would be helpful to you then. As far as partitioning in clockwork that is for the external sd not the internal. The internal should already be set up and should not need bothered at all. Have you data reset your tab at all? I asked becaus that is where this thread comes to play. Some of the tabs internal memory goes bad and will not delete anything thats why it needs to be removed physically. If it goes had some off the app gets left behind and when it boots you cannot install,unistall or really do anything with it.
[Galaxy Tab General] Kemotar:
I've done a couple factory resets, and also flashed a rooted kernel. All that seemed to work fine but didn't fix the problem, and like I said, installing apps seems to work fine. In fact everything seems to work fine until an app tries to save a file to the internal SD, or I try to browse the internal SD files. It seems that the app data works... just not the user files (the stuff you'd normally see in a file browser, or that would mount as USB storage)

I wouldn't really worry about it, since I can install and external SD and make most things work, but I'd like to sell the thing and if there's a reasonably easy fix, I could probably get more for it!
