Jt, I followed your instructions. It gets past optimizing apps, but then the google services framework fc's and it reboots. I've tried wiping data/factory reset, etc. Partitions are 24gb fat32 / 5gb ext4 / 35mb ext4 with activate text file at the root of the sdcard. Any suggestions?

Edit: I figured it out. Setup a 24gb fat32/4gb ext4/100mb fat32 partition configuration.

Have you removed your internal SD? Curious if it works in all configurations as I obviously can't test it all.

It works without removing the internal memory, but is incredibly slow to boot, install, or load apps. Once the app loads (angry birds star wars), it works fine... Samsung wants $107 to replace the system board. Currently looking for a tab with a broken screen to swap parts. Couldn't find the system board on eBay.

Hi ! Thanks a lot for the tutorial, it's very helpful. I do have an issue, though, maybe someone can explain...

I'm in the middle of doing the procedure: I just closed back the device (after almost destroying it for good, but it does seem to start up) and modified my ROM.

Now I need to connect it to adb, but I'm new to all this... I found a few tutorials explaining how to setup adb and fastboot, but as it happens, it doesn't detect my device in download mode as an "adb device". On all of these tutorials regarding driver issues, it was always mentionned that the device needs to be in "debug mode". The thing is: the reason I'm doing this whole thing is that my device (SCH-i800) bootloops on the VZW logo, so there is no way I can access the "debug mode". Is the download mode supposed to be enough to do this?

I've tried a few things on my windows 7, now I'm going to try it with ubuntu...

If anyone can give me a hand, that'd be great. Thanks again for this tutorial, and excuse me for my dodgy english.

I hope someone is still watching this thread...

I have a SGT SCH-i800 that exhibits the problem described in the OP. I successfully got CM10.1 nightly to boot from SD card using the instructions in a later post. But I would like to be able to flash other ICS ROMs as well, so I am trying to follow the steps in the OP to be able to do that. I partitioned the SD card and modified the ROM I want to install etc.

But when I get to this part, I run into problems:
Loading the Modded ROM to the SD:

[background=rgb(245, 245, 245)]Because we messed with the SD Cards, CWM will have a bit of trouble finding the external SD Card (until we flash our ROM).[/background]

[background=rgb(245, 245, 245)]Go ahead and connect your device to your computer and ADB the following command:[/background]

adb shell "echo /dev/block/mmcblk0p3 > /sys/devices/platform/usb_mass_storage/lun0/file"

[background=rgb(245, 245, 245)]That will allow you to access your SD Card from your PC, just copy your modded ROM to it.[/background]

[background=rgb(245, 245, 245)]Now, issude the following command:[/background]

adb shell mount /dev/block/mmcblk0p3 /sdcard

[background=rgb(245, 245, 245)]This will allow you to install the .zip file from CWM, go ahead and do it. [/background]

[background=rgb(245, 245, 245)]It appears as though I get access to the SD card from adb and I can drag/drop the modded ROM into the SD partition, but when I try to adb shell mount... so I can flash the zip I get an error that the directory is busy. I can't do anything at that point so I boot back into CM10 and start over. When I go back into CWM and start over it appears as though the modded ROM I had previously put in is no longer there. [/background]

[background=rgb(245, 245, 245)]Any thoughts?[/background]

on my Sprint Gtab, the relevant device names are /dev/block/mmcblk1p3, etc.

Also I have better luck with the CM10.1 ROMs than the CM10...

Thanks for the reply. How did you know that the "mmcblk1p3" was different than in the OP instructions? How do I find this out for my Tab?

you can see device names with the mount command in the terminal window, or adb shell mount.

Happy to report that all previous problems I had, particularly with CWM being trashed, etc are resolved in the newest CM10.1+Humberos+TWRP ROM.
It uses TWRP recovery instead of CWM, and it works great and still remains after CM10.1 is loaded.

I'll also warn anyone trying to do this on a Class 2 microSD card: Don't, way too slow. Consider Class 4 to be the minimum for acceptable performance.

And as far as partition sizes, I ended up using a 16GB card and did 14GB FAT32 (/storage/sdcard0), 900MB EXT4 (/data) and the remainder (about 200MB for /cache). It fits well without a lot of waste. The Windows program MiniTool Partition is indeed a very good utility for this purpose.

Maybe someone can help me, i am having a little difficulty getting this to run off the sd card, and i think the recovery i have on the device is too old. It is a verizon version of the tablet, SCH-I800 The recovery that i have installed is CWM-based Recovery v4.0.1.5 which i was able to flash to the device via Heimhall. That recovery came as a bin file. i believe i may have to have CWM-based recovey 5.0.x.x but i am having difficulty locating the bin, and a zip install of the recovery from get.cm freezes mid-install and when i reboot device, the 4.0.1.5 is still there. I tried the adb method and i am able to send to it, and to mount. Also, with an 8gb class 4 sd, partition is laid out 5.5gb fat32, 2gb ext4, 500mb ext4. When i put the zip of android on the sd card i should put it on the first partition along with the data_sd file, right? Any advice on getting a newer recovery and cyanogenmod working ,I am trying to get this device working for my girlfriend to us for school, and any help would be appreciated.

Hey all!

I've been following this guide in an attempt to fix my Verizon tab 7, and I've gotten everything to function except the installation of the Rom.

I've re partitioned the external sd card with 3 partitions, 2 ext4 500mb and 1 fat32 with the rest of the storage.
I can mount the sd card using the adb command, but when I try to install it using CWM 5.0.2.7, I get:

Installing: /sdcard/cm-9.0.0-p1c.zip

finding update package...
Opening update package...
Installing update...
Installation aborted.

I'm fairly new at this, so It's entirely possible that I've screwed up something very simple.

Thank you.

 

[Lafein]

An update!

I got the Nightly 10.1 to install after some tinkering and just general patience.

All is well with the exception of SD storage. I can't use the Camera or any app that requires external storage.
The FAT32 partition is 1g, ext3 14g, and the ext4 is 100mb.

 

[nybs31]

Has anyone gotten this to work recently? Downloaded newest CM 10.1 nightlyfrom the link JT provided in an earlier post. I tried JT's way first. I created 3 partitions; a 27 GB fat32, a 4 GB ext4, and a 100 MB ext4. The fat32 partition was first, then the 4 GB ext4, then the 100 MB ext4. I also created a file called activate_data_on_sdcard and put it on the root of the fat32 partition. I was able to get the tab to boot, but stuck at spinning circle boot ani. Then I disassembled the tab, chipped off the nand flash, and reassembled the tab. That was a tough task. I did break off a few of the tiny things surrounding the internal nand flash. I hope that didn't affect anything. Now when I boot into recovery, I am unable to mount sdcard to flash anything. Where do I go from here?

Edit: the activate_data_on_sdcard file I created was a text file. I just right clicked the sdcard and placed a new text file and renamed it to activate_data_on_sdcard. Is that correct?

I had to partition my SDcard differently from what the guide suggests. I'll grab my Tablet, and let you know.

Also, what I found was when I was installing the ROM, I had to make sure the screen stayed awake, I don't know if this had to do with using the external SD card or not, but it would interrupt the installation and fail if I let the screen sleep.

So what did you partition the SD card to? I have a 32GB SD card. What should my partitions be? I'm ready to partition now. Thanks for replying and thanks for your help.

Please help,after done removing internal sd, my phone can boot to download/recovery. problem now, can't connect using adb. adb devices, device not found. any other way to make changes to the system folder, to apply the changes? thanks in advanced

 

[tinpanalley]

Question, will this work with the stock recovery version 3e? If not, is there something I can do?

no you have to have a custom recovery.
