Hi,
I was reviewing the ubuntu thing I mentioned here:
http://forum.xda-developers.com/showthread.php?t=908502
and I was TRYING to be careful, but I messed up.
What happened was I was looking at the "unionfs" file that came as part of that, and I mistakenly thought that it was an executable, so I figured I could get some help if I did "unionfs -?". It was originally in /sdcard/ubuntu, but I couldn't run it there, so I copied it to /data/local/bin, which is in PATH, then I did "unionfs".
I got some errors, which kind of indicated that it was some kind of script, so I looked at it:
Code:
busybox insmod unionfs
mount -t unionfs -o dirs=$mnt/etc=rw:/etc=ro unionfs /etc
mount -o remount,rw /
ln -s $mnt/lib /
for x in \
bin boot home media mnt \
opt selinux srv usr var
do
ln -s $mnt/$x /
done
rmdir /root
ln -s $mnt/root /
mount -o remount,ro /
mount -t unionfs -o dirs=$mnt/sbin=rw:/sbin=ro unionfs /sbin
mount -t unionfs -o dirs=$mnt/dev=rw:/dev=rw unionfs /dev
mount -t devpts devpts /dev/pts
I haven't gone in detail to figure out exactly what that did, but I think it might've rm'ed /root plus maybe /data, and I think that that really messed up my Gtab, because after that, I keep getting the process.acore FC popups !!
I found this thread:
http://forum.xda-developers.com/showthread.php?t=886972
I have the TNT 3452 update.zip, so I copied that over to /sdcard, created the /recovery/command, and did a stock recovery, which seemed to go ok, BUT, even after that, it's still giving the same FCs on process.acore ...
Like that thread, I can't get into Settings, and get the process.acore FC when I try, so I can't try to clear the Contacts data.
So, I figured I'd better stop at this point (yes, I know, I should have stopped way earlier ), and get some advice about how to proceed.
My goal is to try to get back to stock 3452 again, obviously, without the FCs.
So... What to do at this point???
FYI, I have adb access, and I think that I have a working nvflash executable on one of laptops. Is there any way to fix this, i.e., maybe extract some stuff from somewhere and "adb push" it over to the Gtab?
Or, is a full nvflash the only way, and, if so, can you point me to exactly which thread, etc., so I don't mess this up anymore?
Thanks!
Jim
FYI, folks on the IRC helped me get things back.
I had to install CWM 0.8, repartition, then re-install CWM, then flash 3452. It's all back again now.
Later,
Jim

I seem to be frequently flashing or messing up my G1 so I decided to write some shell scripts to help out but they seem to only half work if at all. Actually I'm not sure what they did because they displayed no output.
This script is supposed to backup the default init.rc and mountd.conf files then replace the existing ones with the modified ones.
Though it does not work.
Code:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
mkdir /system/sd
busybox cp -a /system/etc/mountd.conf /sdcard/recovery/mountd.conf.bak
busybox cp -a /system/init.rc /sdcard/recovery/init.rc.bak
busybox cp -a /sdcard/recovery/mountd.conf /system/etc/mountd.conf
busybox cp -a /sdcard/recovery/init.rc /system/init.rc
then this is the next set to move the apks and the program caches which doesn't work.
Code:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
busybox cp -a /data/app /system/sd
rm -r /data/app
ln -s /system/sd/app /data/app
busybox cp -a /data/app-private /system/sd/app-private
rm -r /data/app-private
ln -s /system/sd/app-private /data/app-private
rm -R /data/data/com.android.browser/cache/webviewCache
ln -s /sdcard/cache/webviewCache /data/data/com.android.browser/cache/webviewCache
rm -R /data/data/com.android.vending/cache
ln -s /sdcard/cache/marketCache /data/data/com.android.vending/cache
rm -R /data/data/com.google.android.street/cache
ln -s /sdcard/cache/streetCache /data/data/com.google.android.street/cache
reboot
Plus both run and output no errors either. Who knows what problems I'll run into because I have no idea what they actually did.
Anyone see anything wrong here?
Well I'll help you.
1-) After you back up the mount and stuff and put the other back, you MUST reboot before keep going.
2-)After boot then you can copy the files or make the symlink. I suggest you dont copy the app to the sdcard on teh scrip since they should be there already. so do that manually once then the script just delete the folders and then crate the symlinmks.
I have a menu that does that and I have got some experience as why it works one day and not the other.

I took the reboot out after the mountd.conf and init.rc did not appear to copy due to the lack of /dev/mmcblk0p2 hoping to see some sort of output why it did not run. Unfortunately it runs and backs up the files but does not replace them with the modded ones.

Not copying the apps is a good idea, modified the script to not do so.

Does Android require that you do a chmod on all shell scripts first?
On Debian I usually just use sudo sh ./ and it runs the script w/o changing anything on the file permissions so I figured Android would be similar if I just ran them as root. Still I see a lot of people requiring a chmod 777 on any guide referring to running shell scripts.
I will try that and report back with my findings. Thanks for replying.
Does Android require that you do a chmod on all shell scripts first? I just have to type m oon anywhere in the androud shell and my scripts run, for that i put it on /system/bin and do a chmod 4755 to the file. it is still needed to type su before you run the script.
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
mkdir /system/sd
cp /sdcard/media/Data/mountd.conf /system/etc/mountd.conf
cp /sdcard/media/Data/init.rc /system/init.rc
Thats my code for copying the modified files to the right place. So maybe you should try that.
Oh for androoid you dont unless you put it on /system/bin then you will have to use sude and sometiems it still wont run due to lack or permisions so is better to do a chmod 4755
Well I made the changes suggested and did a chmod on all the files prior to running but with no luck.
The odd thing is if I use the shell scripts as a guide list it works perfectly but if I try to launch them as a shell script all sorts of strange undesirable things happen to my phone.
The time consumed trying to use the scripts and recover from what happens from what they do out weight the effects of typing everything in.

you can only run the script once .. when the "ln -s" has already been done it has to be undone before trying to run the script again .. otherwise you would be copying the files onto themselves .. not sure if you've tried running it more than once

These scripts were intended for my usage after a system restore from a update.zip file which wipes /system in the process.
My intentions were to:
1. remount the fs rw
2. copy the original init and mountd files to the sd then copy the modified to their respective places in the system folders then reboot
3. reboot then create the sym links appropriately then move my caches too
Well unfortunately the only thing that works is the backing up of the original init and mountd files.

yes .. but you can't create the sym links when they already exist .. running the update.zip only wipes the /system .. not /data .. if the links were there before the update.zip they will be there after
I am going to bring this up to the group. I am looking for the method to block the OTA updates. I enjoy my rooted Evo phones. It is a freedom I enjoy and plan to protect.
I am getting tired of pressing cancel every day. If I want to update, I want to be the one to control it.
I have been looking for a method to disable the OTA update prompts. From the board, I was able to find this.

Anyone know why otacerts.zip is in use and cannot be renamed. I did some different methods, but no luck.
Has someone done this before or knows of a better method of blocking the OTA updates from Sprint. I am open for a solution.
check with chuckhriczko, he successfully completed what you are trying to do. Also check out his ROM...it already has this action implemented into the ROM

I am assuming you are in the system when doing this? If so, you need to back out into recovery and do it. We currently don't have write access to the system partition while Android is running. Only in recovery. Highly recommend you look up Rom Manager on the market and use that to install the "fake-flash" recovery. It's truly the best recovery we have atm.
But you are doing it correctly except you wrote cd /etc/security. It should be /system/etc/security. The following is all you need.
Code:
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
cd /system/etc/security
mv otacerts.zip otacerts.zip.bak
You can ls to make sure it worked but that should do it. Reboot and voila. Never press cancel again.

from my brief experience last night with this, /etc is a symlink to /system, so /etc or /system/etc is the exact same thing, doesn't matter.
i took the build.prop in the PC36IMG.zip which shows itself with test-keys, removed those and used release-keys, and the OTA appeared when it hadn't before!
now it downloaded the OTA but verification failed. i had to copy over ota-certs.zip from a stock EVO and those allowed the OTA update to pass verification.
if you wanted to reverse the process and prevent OTA updates from downloading, you can manually change your build.prop to show you as already having .6 software package loaded and it won't show any OTA available anymore.
it might be better to actually load the .6 software though which will adjust the build.prop, but thats my personal recommendation and not related to your request. im also running PC36IMG.zip on .1 software and also get the OTA update prompt but i plan on loading .6 software soon.
another factor to consider is the radio version also ...

Oh I didn't know about the symlink. Good call.
Good point. I forgot to mention I did change the build number in the build.prop to be .6 instead of .1 so maybe that helps.
chuckhriczko,
I first tried it in system and no luck, then I went to recovery. I figured the active system partition was the issue.
Now I know I was in the wrong place. I will get Rom Manager and take a look at your customized ROM.
Nice job on the ROM. Love to say goodbye to those Sprint Apps.
Thanks for the quick response.

How about:
adb shell
su
pm disable com.google.android.gsf/com.google.android.gsf.update.SystemUpdateActivity
pm disable com.google.android.gsf/com.google.android.gsf.update.SystemUpdateService
pm disable com.google.android.gsf/com.google.android.gsf.update.SystemUpdateService\$Receiver
This should disable the OTA updates without removing any files from system.
Hey guys,
Loaded BAMF 1.5 yesterday and have been enjoying the ROM thus far. However, I've been trying to push my custom widget.txt to the \system\customize\ folder so I can have my own power controls in the notifcation bar. I have tried the Mount rw/ro app from the Market, and have also tried mounting rw using adb (mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system).
Each time, when I use the command: adb push widget.txt /system/customize/ I get the error: failed to copy 'widget.txt' to '\system\customize\': Read-only file system
Where am I going wrong?

I'm pretty sure the TB is using EXT3, not YAFFS2.
Try
Code:
mount -o remount,rw -t ext3 /dev/block/mtdblock3 /system
Even easier, assuming you have busybox. busybox mount isn't as lame as the standard mount which is provided, so you don't have to tell it as much, it can figure things out on its own:
busybox mount -o remount,rw /system
busybox mount -o remount,ro /system
Click to expand...
Click to collapse
even easier.
sysrw
sysro
Doesn't anyone ever read the first post of my rom?
I'm an idiot. Thanks for the ext3 vs yaffs2 reminder.
I'll try busybox at some point also to check
And to Adrynalyne, apparently I didn't read the first post...my bad. Thanks for reading mine, though. I'll pay closer attention in the future.

On my previous HTC phones, I was able to mount an ext4 partition simply by doing:
Code:
mount -o remount,rw /
mkdir /storage/sdcard3
mount -o remount,ro /
mount -t ext4 /dev/block/mmcblk1p2 /storage/sdcard3
Problem is, I can only see the files in terminal. None of the other apps can see anything, even with root access. Anyone been able to do this successfully on this phone?
Bump. From the terminal, I see no reason why this shouldn't work. I've mounted with the same options as other partitions, and even used chmod and chown to modify permissions to be identical to those in other mounts. I'm not sure if this is a KitKat issue, or something HTC has done to the ROM itself.
I've been able to do this on both my Incredible and Rezound, both with stock and AOSP ROMs. I'm really stumped why I can't get this working on my M8.
Back in 5.1.1, I was able to mount the system partition.
Now in 7.0, I couldn't mount it anymore without making my phone crash
I've tried different methods...
Code:
mount -o rw,remount -t ext4 /system
This crashes my phone
Code:
mount -o rw,remount,rw -t ext4 /system
This reports back "...Device or Resource busy"
So then I was thinking that something might be using that directory so I tried to make a system mount point in /mnt, thinking as processes depend on /system, I must make another mount point
So I did, this time, "mount" says system is mounted with "ro,seclabel,relatime,norecovery" as it's option. so when I changed it to "rw,seclabel,relatime,norecovery", it doesn't mount, with no errors
So I tried, with system mounted on /mnt/system,
Code:
# mount -o rw,remount -t ext4 /dev/block/sda18 /mnt/system
(don't worry I know you can do ".../platform/xxxxxxxx.ufs/by-name")
This ALSO crashes my phone
So I pretty much gave up, and looked online, and all I found was the same process, but nothing on "this crashes my phone" or any other.
Agreed
I had the same problem. Hard lock up of phone.
