Phone keeps downloading OTA updates -- using lots of Bandwidth

I got message from tmobile saying I had used over 10GB this month, which seemed not right to me.
Looking at my bandwidth usage on tmobile's site I saw lots of 40 MB downloads. So I ran tcpdump on the phone for a while and it looks like maybe my phone keeps downloading an update several times a day from google?
There is a GET /updates/signed-kila-ota-150275.53dde3 to IP of 74.125.47.101 .
I am using a JF build: 1.5 CRB 21 147201 test-keys.
Anyone know why this is happening if what I think is happening is in fact happening Or how I might stop it?
Also, I didn't delete the oacerts or cacerts files:
# ./bash
bash-4.0# cd /system/etc/security/
bash-4.0# ls -l
-rw-r--r-- 1 0 0 47159 Aug 1 2008 cacerts.bks
-rw-r--r-- 1 0 0 1107 Aug 1 2008 otacerts.zip

You could try 1 of 3 of JF's solutions:
1. delete the otacerts.zip file manually. The file is at /system/etc/security/otacerts.zip But keep in mind if you use this method your phone will continuously re-down the OTA and try to verify it, which is bad on your bandwidth usage and your battery life
2. Replace /system/build.prop on your phone with the one from the ADP1 version of JFv1.51
3. chmod 000 the OTA file in /cache (unconfirmed solution, but is likely to work)

[THINKTANK/DEV] using vibrant without the internal sdcard

::::::::::::::::::::::::::::::::::::::::::EDIT::::::::::::::::::::::::::::::::::::::::::
i was out for my job and was busy guys......but im again initiating this discussion.................
now im using a 8 gb external sdcard with 1 gb ext4 partition and 7 gb storage...with offcourse modified vold.fstab.......everything works what should in cm7.....im happy and can live with it ......but im tempted to use gps and also want to get good battery life now
so i installed cm7 partitioned external sd with 1 gb ext4 7 gb fat32 storage then odined to 2.2 rom and changed the vold.fstab file......i get 7 gb storage partition mounted but the 1 gb data partition is not mounted.....i tried converting to jfs also from eugenes kernel but it still does not mounts......anyone know how can we mount /data from the external sd partition?? any help from dev side would be highly appreciated .....im noob at linux.... please share opinions.....
PS:my primary aim is to load a 2.2 rom and use it WITHOUT internal sdcard.....
also since i have /system partition inside phone memory...is it possible for the nand to be damaged?? i guess /system partition and other /cache partitions all are in the nand.....am i correct?? maybe we only messed mbr!!!
ANY OPINIONS ARE WELCOMED

OLD POST:
For the background....my samsung vibrant bootlooped after installing dow kernel....after that I was unable to mount my internal....the 16 gb space disappeared.....however I can boot to eugenes froyo 2e recovery rom....nothing else boots the phone.
.i am not linux guy but have some programming skills....so after reading some threads was able to mount external sd as internal sdcard...im happy that the phone is 70 % working as I can listen to music and click photos and record my jam with voodoo soundfix.ps I flashed deadhorse succesfully.....
Now the thinktank part comes.....
can anyone help me mount /data at the external card. which files do I need to edit...
Where should I start?
also I have a feeling that the movinand cannot be damaged that fast.any way of resetting the memory manually?
give any thoughts but dont say send it to tmobile.....im at the opposite side of the globe from USA.......I need to fix it as far as possible and use it.
For those in same situation here is the file....
copy it to /etc folder either from adb or root explorer
it will mount ur external as internal

tempted to see this. Might be able to add onto it to get External mounting inside the internal for Frost.

Do we have a copy of what the the device mappings *should* look like? Someone commented that what our phones are actually trying to map looks like an I9000 instead of a Vibrant.
My previous android hacking has been with a chinese tablet. I don't know what partition numbers should go where on the Vibrant.
An additional thought for anyone it might help. As I was trying to troubleshoot this mess on my phone I noticed a difference between Eugene's ROM (that will boot) and the other ROMs I tried. May or may not be important but Eugene's ROM is overwriting almost all of the partitions. The other ROMs I've looked at just overwrote two or three. Eugene's doesn't overwrite the Recovery partition.
If this were my tablet I would be looking for a good dd image dump of /dev/block/mmcblk0p4 to also overwrite the Recovery partition. I don't know what that should be on the Vibrant. (I have a dd dump of my system partition from the Vibrant but not the other partitions.)
Anyone got a partition map or chart?

When this happend to me I just went into download mode and flashed a stock kernel with odin. was that just not possible for you?

You got lucky if the same thing happened to you. In most cases the zapped internal SD issue didn't happen when we flashed the DOW. In my case I ran the DOW kernel for a week to ten days. One day my phone was totally unresponsive (black screen, no lights, no response from any buttons including the power button). I pulled the battery and it was fine. It happened again another day. Again, pulled the battery and it was fine.
The third time this crash happened after pulling the battery my phone froze on the bionix robot girl at boot. I tried pulling the battery because nothing else worked. Same thing -- stuck at bionix girl.
I tried to flash a stock kernel. After flashing the stock kernel with Odin (successfully Odin said) my phone would power up to the Vibrant logo then shut off after displaying the vibrant logo for 1 second. If I plugged my phone in the battery logo would loop as though the phone were continually resetting.
I repeated the Odin flash four or five times to stock with the same results. Every time Odin said the flash was successful. I tried a different computer. Same result. I tried a different stock kernel. Same result.
The only ROM I found that will boot my phone is Eugene's. I tried flashing stock after Eugene's Froyo. My phone went right back to the logo/1 second/power off behavior. Flash back to Euguene's Froyo and my phone would boot.
I tried to boot to Recovery. My phone would not boot to Recovery except if I have Eugene's Froyo installed. I tried to ADB to my phone - works under Eugene's Froyo but not under any other ROM I've tried.
With Eugene's Froyo I discovered my phone said it had 0 MB application storage space and was not mounting either internal or external SD card. Each time I reboot my phone it loses my accounts and most settings. Oddly it keeps some settings like the static IP address for my wifi connection -- but not the password for my wifi network.
After further investigation I found my phone recognizes the external SD card but so far I have not found any way to access the internal SD card. My phone does not recognize the internal SD exists.
The trick with changing the vold.fstab to map the external SD to /mnt/sdcard gets the External SD card mounted and tricks the phone some but doesn't get back any application storage.
These symptoms match a whole group of us who installed Team Whiskey's DOW kernel. We've posted on Team Whiskey's forum and last I checked gotten no response. Team Whiskey still had the DOW kernel available for download.
Search XDA for "DOW sd" and you'll find a bunch of related threads.

Hi guys just to let you know......you can flash bionix rom by installing it through cwm recoyery...open the zip file from windows explorer....inside system/etc....replace the vold.fstab with the one above and flash......you will have bionix...tested with 1.2.1 but should work with recent one....running deadhorse kernel with bionix 1.2.1 without /data lol
Also im trying to make a rfs partition in ext sdcard and mount it...but since my work is all hit and trial it who knows........also any guidance on how to mount /data to external sd would be welcomed......i know its logically possible....trying with parted to partition 2 gb sd to 600 mb rfs for /data and rest for /sdcard...any help gentlemen..

Some people are soo foolish and they seem to act so smart...lol...odin with repartition......lol....ive been doing it from 2 weeks....it does not work.....thats why this thread is here morons........and u just pass by and say odin with repartition....and another fool comes in and says +100000 lol.......god have mercy on these two guys....help them...lol
@binary....install twice...maybe 3 time

My advice is to send the phone back to T-Mobile. DOW burned out the internal memory. I am.
And don't mind the wankers... they haven't learned to read threads before replying and looking stupid.

but on the other hand yes some internal sd fail i dont think yours did since u can boot inm to bionix i odnt know im such a noob that it doesent make sense to me that your internal memmory failed but u bootin in to bionix .

Seriously ?
OP already said he's on the other side of the globe. And just like myself and many others, this is more of a hard brick.

Let's stay on topic here people and play nice.

Actually, this sounds like a classic case of overheating thus----heat damage
All need to remember that a minor loss of insulation results in brownout in electronic devices. Or better put, 4 or 5 molecules of insulation
Either way return it or buy a new board.

I checked. No brown on my board, yet I have the same exact issues.

it's init.rc i believe, should see something like this:
"mount rfs /dev/block/mmcblk0p2 /data nosuid nodev check=no"
i'd avoid using a FAT formatted partition, since pulling the card in the middle of a write could result in data loss.

[Kernel/Initramfs]Tab 7.7 Githubs

These are git repos for the initramfs that I pulled from the Austria Firmware and the Kernel Source downloaded and reuploaded to github. I'm going to fork and start working on a kernel for when I get the 7.7 myself, but if anyone else wants to start working on it and use them, feel free.
Kernel is still uploading, mistakenly reuploaded the initramfs twice. (Facepalm)

Enjoy guys!

I have a 6800 device imported from Hong Kong and have been trying to figure out how to port CWM recovery to it. I work as a developer but I haven't looked at this before as I haven't needed to
So far I have rooted the device and had a dig around the filesystem. The partitioning looks similar to the 7 plus:-
179 1 20480 mmcblk0p1 /efs
179 2 1280 mmcblk0p2 /boot
179 3 1280 mmcblk0p3 /mnt/.lfs
179 4 8192 mmcblk0p4
179 5 8192 mmcblk0p5
179 6 8192 mmcblk0p6 / recovery
179 7 204800 mmcblk0p7 /cache
179 8 16384 mmcblk0p8 <radio/modem>
179 9 851968 mmcblk0p9 /system
179 10 13791232 mmcblk0p10 /data
179 11 458752 mmcblk0p11 /preload
179 12 8192 mmcblk0p12
I'm trying to figure out what's in 4,5 and 12.
I have the kernel source code downloaded and buildig and I'm now looking at where to go next. If anyone can post any links to resources on the web which might speed up the process then it would be most appreciated. I don't have a lot of time to spend on this.

Could you "if dd" them and send me a link? I'll be able to find out which is the recovery.img. ;-)

Thanks - that helps confirm what I had found by digging around and completes the list of partitions.
I have now extracted initramfs from both the runtime and recovery kernels.
Now I need to find time to do some reading on how to port CWM recovery.
Anyone know whats in the param partition?

A quick update....
The partitioning for the 7.7 is very similar to the 7plus.
I have been in contact with the garyd9 who ported CWM to the 7plus and he has given us a few pointers including his github username.
See:-
http://forum.xda-developers.com/showthread.php?p=21717604#post21717604
Interestingly he says that it's likely that the samsung's kernel source release will not have the correct defconfig so we are going to need to tweak it.
The recovery binary gets compiled from the Cyanogenmod sources which are easily obtained.
Unfortunately I'm going to be tied up with my day job for most of this week but will try and look at this again on Friday.
Is there anyone that can keep the ball rolling while I'm busy?
Thanks

I'm getting this one and selling my Note. I'm so excited to see you guys working out of something for P6800 here.
Thanks to all devs in advance!

Anybody want to buy my outdated,used Note?
Hehehe.. well, at least I just *seconds ago* ordered my Tab 7.7 from ebay uk.
Let the modding and ROM flashing begin!

@Lucid what's wrong with your Note..?

There is nothing wrong with my Note, it is the best phone I've ever had.
So I went ahead and bought the 7.7 to see if that one is even better. Needs to arrive still.
I intend to use it as a daily phone and will keep it to my ear if needed,
no matter the reactions of other people.
Gadgetwise, I live for myself, not the general public.
I might sell on of them, but history shows I keep all my "old" phones.

I use my galaxy nexus for day to day but since finding out about phoneleash i dont really touch my phone anymore.. check out phone leash if you have two SIMs.. although i guess it can work with GV also..

Tab 7.7

I placed my 7.7 next to my Titan, Sensation and the Galaxy Note today to see how it fares, no way is it practical to put to the ear and it is pretty ridiculous to carry. It's a compact device but not THAT compact. My Kindle Fire was more handy. The bezel is too large.
However, the phone functionality is superb and if one can find an unobtrusive way to carry it, we could finally unify our communication requirements in one device.

Ddraig - I have been trying to get this get up and running.
So far I have managed to compile a zImage (recovery.img) using pretty much with the default config. Flashed through heimdall
I have used garyd9 recovery_initramfs, used his /sbin folder as is. The rest of the files are taken from the stock gt-6800 ramdisk inc modules. Where necessary make changes to partition entrys.
It boots in to clockworkmod recovery fine. It can mount all partitions but not /cache partition properly. I have checked the path and it seems correct ??
(I can mount via adb but cwm says it cant find it)
I will try building recovery binary at some point but will be busy for some days now.
I can you sent you some of my config files / recovery.img if it helps.

Sounds like you have made some progress with custom recovery, you need to be careful if you are using garyd9 recovery_initramfs on your device, note one i think this for a wifi device being p6210 if you device is a p6800 check all the mounting points as there are some slight differences between wifi and 3g devices. how did you compile your source and make compatible odin file. i'm on a mac and so far i can't get heimdall to work with p6810.

After 2 days of kernel building and insmod, I've finally got a P6810 module to insmod successfully into my stock device. This is the config. It comes from the samsung source (GT-P6810_HC_Opensource) download with some DEBUG params turned off, and the local version set for the Australian DTKL5 firmware. I hope it can help someone avoid some trial and error pain. The p6800 guys may be able to turn off similar debugs and get theirs working. This is not fully tested, if you find other params that need changing please advise.
EDIT: I flashed this kernel to my device and it worked.
Here is more information on the environment.
CodeSourcery toolchain arm-2009q3-67-arm-none-linux-gnueabi.bin
Change the supplied Makefile CROSS_COMPILE to point to installed toolchain (eg, /home/davp/toolchains/arm-2009q3/bin/arm-none-linux-gnueabi-)
Copy the supplied file to .config in the directory where you unpacked the kernel source, then run make
Links http://forum.xda-developers.com/showpost.php?p=21870378&postcount=23 for how to do a basic initramfs to go with the new kernel (the result of this is running a command like: make -j5 CONFIG_INITRAMFS_SOURCE=initramfs_root, and then tar and flash the zImage).
Copy of the .config file (from the kernel directory):

Can you confirm you have suscessfully compiled and flashed a working kernel?
I want to have a crack at custom recovery for the p6810, i'm pretty confident we can getting going using a blend of sources from https://github.com/garyd9/initramfs_recovery_GT-P6210 and our kernel stuff.

Oh great - the 7.7 also has binary-only modules?
Freaking Samsung, I thought they were making progress with the I9100/I777 (100% open-source kernels, no proprietary modules).
Good luck bedwa - feel free to browse my github for Exynos tips (although much of it will not directly patch onto HC kernels), garyd9 knows what he's doing too.

[HOWTO] Root the Galaxy Tab 2 7" without flashing the bootloader

Hi,
Here's a method based on a security hole to gain root on the Galaxy Tab 2 7" without heavy flashing by Odin. I've successfuly tested this method on my GT-P3110 running stock Android 4.0.3 on kernel 3.0.8-379370, version IML74K.P3110XXALD4.
The original post by Miloj :good: can be viewed here :
http://forum.xda-developers.com/showthread.php?t=1704209
I've only "translated" the trick from TF300T to our Galaxy Tab. I guess it should work for other devices too... To make short, the goal here is to create a symbolic link from the famous /data/local/tmp to the block device on which /system is mounted. The mount command runned in an ADB shell can give the required information :
$ mount
rootfs / rootfs ro,relatime 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,mode=755 0 0
devpts /dev/pts devpts rw,relatime,mode=600 0 0
proc /proc proc rw,relatime 0 0
sysfs /sys sysfs rw,relatime 0 0
none /acct cgroup rw,relatime,cpuacct 0 0
tmpfs /mnt/asec tmpfs rw,relatime,mode=755,gid=1000 0 0
tmpfs /mnt/obb tmpfs rw,relatime,mode=755,gid=1000 0 0
none /dev/cpuctl cgroup rw,relatime,cpu 0 0
/dev/block/platform/omap/omap_hsmmc.1/by-name/FACTORYFS /system ext4 ro,relatime,barrier=1,data=ordered 0 0
/dev/block/platform/omap/omap_hsmmc.1/by-name/DATAFS /data ext4 rw,nosuid,nodev,noatime,barrier=1,data=ordered,noauto_da_alloc,discard 0 0
/dev/block/platform/omap/omap_hsmmc.1/by-name/CACHE /cache ext4 rw,nosuid,nodev,noatime,barrier=1,nomblk_io_submit,data=ordered 0 0
/dev/block/platform/omap/omap_hsmmc.1/by-name/EFS /efs ext4 rw,relatime,barrier=1,data=ordered 0 0
/sys/kernel/debug /sys/kernel/debug debugfs rw,relatime 0 0
After identifying the block device, refer to the well-explained Miloj post and consider :
Code:
[COLOR="Red"]FOR SAMSUNG GALAXY TAB 2 7" ONLY:[/COLOR]
Code:
$ ln -s /dev/block/platform/omap/omap_hsmmc.1/by-name/FACTORYFS tmp
$ exit
Hope it will help !

Well, you must follow Miloj's tutorial http://forum.xda-developers.com/showthread.php?t=1704209 from the start : push the binaries downloaded from http://db.tt/FBUNeVmo to /data/local, run an ADB shell and change directory to /data/local, move tmp to tmp.back then create the symbolic link to the block device with the ln command given in my post for the Galaxy Tab and type (or copy / paste) all the following commands (reboot, shell, clean-up, dirty work, ...) given by Miloj.
I know it's a little rough, I'll try to find some time to script all the stuff or adapt the one click tool quoted in Miloj's post.
Good luck !

yes it worked .awesome man thank you you rock ,now i have root in stock with binary counter value 0

The automated tool
Sparkym3 provides an automated tool for rooting the Transformer TF300T with Miloj method :
http://forum.xda-developers.com/showthread.php?t=1706588
I've modded the tool for the Samsung Galaxy Tab 2 7" (see attached file). Check the link above for the instructions and run the modded version called RootDebugfs_n95.bat instead of the original RootDebugfs.bat.
The original tool includes the Asus USB drivers... I failed to join the Samsung ones to the attached zip, maybe due to an excessive weight (near 19 Mo).
Happy rooting !

Gee, it's already been impossible with ICS4.0.4
Wish I hadn't upraded...

Thanks Nesquick95, I've updated my topic with your informations.

If the security hole is patched in the 4.0.4 release, you'll get an "access denied" error while executing the "debugfs -w /data/local/tmp" command.
If it's the case, we must look for another rooting trick
Can you please tell which kind of error you get and if it's not the "access denied" one, post the result of a "mount" of your tablet (adb shell mount) ?

First,great job,thank you for your work,now we don't need to worry about warranity.Second,maybe you can help us again,can you please tell us how do we keep root,when upgrading 4.0.4? I know that Transformer tabs have some kind of app,named Root Keeper ,if you flash OTA update,and want to keep root.Maybe we can try something similar for our tab ,or using Mobile Odin maybe?
Thanks again!
Best Regards!

Yep,the whole point of this root method it's not to flash unofficial kernel using Odin,because it triggers the counter ,and it will void your warranity.If you root without Odin,than you can use Mobile Odin to flash roms,and you'll have the counter 0 ,so you'll keep your warranity. intact.
Cheers

Yes, because this root method exploits a security hole of the tab's software integration and thus doesn't need Odin.
But I'd like to say that this kind of rooting method isn't better or worst than recovery flash...
Recovery flash causes warranty to be broken but is nearly granted to work.
Tricky methods keep warranty alive but have short lifetimes, like the one discussed here that seems to work only on 4.0.3, since providers like Samsung can't leave security holes on their systems and apply patches so the work (find a new trick or write an OTA-rootkeeper) must be done each time an update is released.

Man so no method like this forv4.04

Haven't got 4.0.4 myself so it's hard for me to say...
An unsuccessful try on 4.0.4 is reported here and hole patching by Samsung is strongly suspected.
Well, it's always the same never-ending rooting story : flashing & losing warranty or waiting for a rooting exploit that may never be found & keeping warranty alive.
May I ask how 4.0.4 comes to our tabs ? Is it regular OTA or alternative ROM flashing ? I'm on stock 4.0.3, rooted but not unlocked and have no signs of an OTA update coming.

4.0.4 is available from kies only [p3100] No OTA update

Since your alrdy rooted u can flash a recovery via mobile Odin or desktop Odin of your not worried about flash counter. If u guys have a link for your 4.0.4 update ill root and de odex for ya. Or let me know what region the 4.0.4 update is for ill try and find it on samsung firm

Is it possible to sideload apps to the Galaxy Watch 3>

I see that the question has been asked, but no one has answered it. I need to sideload an app to the watch, but all the guides I find are written for the 4 and 5, not the 3 since it still uses Tizen no WearOS. If someone could point me in the right direction for a guide, I would appreciate it!

How to sideload apps into gw3
Hi. So i've been searching for hours and nothing is working. I'm trying to sideload modded aps onto my gw3. So far I've gone through: https://forum.xda-developers.com/t/app-mod-spotify-lite-scaled-for-standalone-use-on-wear-os.3815680/...
forum.xda-developers.com
You use "adb sideload" to move contents into the watch. If you don't know on how to use it, research for the answer. You can mess up the device.

First time writing here, just wan't to clear things up, because i have been doing some research now for a while...
First off all adb is for "normal" android devices (like most phones), you should use sdb because its specifically designed for use with Tizen Os devices (just as they are saying at the thread Maxninja linked, ehm ehm), including Galaxy Wearables, like documented here: sdb - tizen reference
(working with it is very similiar as with adb though)
To sideload apps there is already a very good tutorial in this forum here:
howto-sign-and-sideload-tizen-applications-to-the-gear-fit2-from-windows
-->Important: stick with java version 15, i had 17 installed and got IllegalAccessExceptions due to some linkage Error caused by newer Java versions. Just install an "Amazon corretti" msi (google it), and it should work.
I think the more important question also is where to get .tpk files...
Simplest way is to temporarily link your galaxy watch 3 with a samsung phone, download all the wanted apps, and then do the following
- enable developer mode,
- with
Code:
sdb pull
download the WHOLE folder, where your app is stored (something like /opt/usr/apps/URI_NAME_OF_APP or opt/usr/globalapps/URI_NAME_OF_APP) to your disk.
--> a tpk file has a structure like this, within the galaxy watch: (example)
com.samsung.d-calculator-wc1 : FOLDER
Code:
lrwxrwxrwx 1 app_fw app_fw 69 May 18 16:15 author-signature.xml -> /opt/usr/globalapps/com.samsung.d-calculator-wc1/author-signature.xml
lrwxrwxrwx 1 app_fw app_fw 52 May 18 16:15 bin -> /opt/usr/globalapps/com.samsung.d-calculator-wc1/bin
d????????? ? ? ? ? ? cache
d????????? ? ? ? ? ? data
lrwxrwxrwx 1 app_fw app_fw 52 May 18 16:15 lib -> /opt/usr/globalapps/com.samsung.d-calculator-wc1/lib
lrwxrwxrwx 1 app_fw app_fw 52 May 18 16:15 res -> /opt/usr/globalapps/com.samsung.d-calculator-wc1/res
drwxr-xr-x 3 owner users 4096 May 18 16:15 shared
lrwxrwxrwx 1 app_fw app_fw 67 May 18 16:15 tizen-manifest.xml -> /opt/usr/globalapps/com.samsung.d-calculator-wc1/tizen-manifest.xml
- if it didn't work, try to pull them independently without cache and data folders (or with the calculator example from "globalapps" instead of "apps"
- setup your galaxy watch to your actual phone (therefore factory resetting it)
- follow the signing procedure linked at the top of my post, for each app
- install them via
Code:
sdb install
Hope this helps!
