Cannot Delete texts - Hero CDMA Q&A, Help & Troubleshooting

I'm running Fresh 2.1.1 and I have quite a few texts built up on my phone but every time I try to delete a thread it just doesn't. I press delete, the menu disappears, and the thread just stays there. Any thoughts? If I need to put more info I can, or if anybody can tell me where I can go in adb to delete them? Thanks in advance!

this does it. i had to do this to my gf's hero last week
this will make a backup of your texts on your pc before.
Code:
mkdir c:\temp
adb pull /data/data/com.android.providers.telephony/databases/mmssms.db c:\temp (this will backup the database to your computer at c:\temp, just in case)
adb remount
adb shell
rm /data/data/com.android.providers.telephony/databases/mmssms.db
reboot

Thank you very much!

I cleared the ext partition
BUT now when I push them on .. well TRY to ... it starts gets to about 10 of them and then just stops. I have tried to restart and it stops at different places and just doesnt go all the way from start to finish.

yo thanxs bro so did you fix your problem yet?
no .. not yet gonna try some other stuff to see what works.
if you are using windows Strapt and you are typing that long command each time you want to use adb to push or pull... etc. then just so i can sleep better at night and you don't have to type a book every time you want to push or pull a file then add adb.exe and and adbwinapi.dll to your windows/system32/ directory and you can use adb from any dos directory prompt. (got that info from this thread)

Need help with METROPCS FLASH. Talk Text and Web but...

Hey guys I basically did everything that the Cricket how to said, but with the Metropcs logins and passwords. I have flashed several phones before, but not an Android OS. The phone works with internet and picture text coming in, but the apps. like Youtube and Google maps will only work on WIFI and not on the network and MMS out will also not work.
My assumption is that it has to do with this whole autostart file thing. I am so new to this programming stuff that I am not sure what to do when it comes to this.
So I used QPST and CDMAW to program the back end so that is probably why the Internet works. APN and Proxy settings are all correct, but here is the only place I have an error.
These are the directions:
Before starting the next step make sure you have the u2nl file and autostart.sh in this folder c:/android/tools
"Now go to the command prompt on your pc and type the following commands:
cd c:\android\tools
adb remount
adb push c:\android\tools\u2nl /system/bin/u2nl
adb push c:\ android\tools\autostart.sh /data/opt/autostart.sh
Now:
adb shell
chmod 0755 /system/bin/u2nl
chmod 0755 /data/opt/autostart.sh
reboot"
My error begins when I type the adb remount.... it states unable to find device or something like that.
I plugged phone to computer not in Diag mode or any mode, just turned it off then back on and plugged it in. Is there a setting on the phone I need to check?
Then I go ahead and do those push commands just for the hell of it, it just scrolls through this whole display of things.. not sure what its doing.
The adb shell part works and so do those other commands after....
When I am done with the last line that has the autostart.sh and hit enter...
The phone doesn't reboot, I just unplug and then turn off and then back on. I would have thought there would be a script to reboot phone or something...
So what am I missing or is it not even possible to get Google maps and youtube to work on Metroweb... has to be on wifi??? I have seen people say they have done it...
Any help would be appreciated..

Push Phone.apk

Can someone give me the adb command and/or terminal commands to push a custom Phone.apk?
Thanks
adb remount
adb push Phone.apk /system/app/
Been trying to do the same thing since yesterday.
This is what I get with the two commands posted above:
Code:
failed to copy 'Phone.apk' to '/system/app/Phone.apk': Directory not empty
EDIT:
Trying it again now and it seems to just hang there. It's been over 10 minutes and it doesn't seem to be doing anything (Process status: Sleeping).
All my attempts result in the phone freezing. I have to remove the battery in order to reboot it. Thankfully, I haven't managed to brick it yet, though I suspect I'm getting closer to achieving brickdom with every attempt.
do it via recovery?
Worked like a charm. It fails on "remount" while in recovery and I thought I was doing something wrong but apparently it's not required.
EDIT:
Well the copy worked:
Code:
1224 KB/s (835675 bytes in 0.666s)
but I'm not sure if it actually did anything. The new apk is supposed to change the call screen but it doesn't. Also, while in recovery mode if I
Code:
adb shell ls /system
there's only bin/ directory in there (i.e., no app/). Am I doing something wrong?
S_Dot: Sorry for hijacking the thread. At first it was just to clarify one little problem that I assumed you may have had as well but now it's sorta snowballing.
EDIT2:
OK, I found the "mount /system" option in the advanced menu. Thanks for the help and hope this helps someone.
Achilleas you are AWESOME!
I have been looking for ages how to do this since I always got problems. Finally it worked!
Thanks
can anybody shead some light on this problem. I downloaded file Phone.apk
Voicemail fix
Use adb push to replace phone.apk in system/app
adb remount
adb push Phone.apk /system/app/Phone.apk
adb reboot
I used adb.exe from command; everything went successful, But now cant make any calls or go into setting calls. I get for close error, I made a back up of rom so all good. I tried twice. twice no good, this file must not work with the evo. I have an evo 4g
You could try
Code:
adb shell chmod 644 /system/app/Phone.apk
before the reboot.

[How To] Remove WebTopMod without root! [How To]

Since I was looking to be able to update my phone, I had to remove the WebtopMod. Since the previous instructions required me to root my phone to remove it, which was counterproductive because it would mean loosing the ability to update anyway. I looked through the WebtopMod installation scripts and came up with this guide to remove it:
View attachment WebtopModRemoveGuideNoRoot.txt
Note: I've attached the guide in a separate file, because the forum is stupid and thinks that exe, bak, odex, apk, and dex are valid TLD's and says I can't post external links. If I ever get "approximately eight" posts I'll put it in this post.
If you don't have the original backup files, look in page 3 of the howto post for removing it with root. (Thanks, MotoAtrixFan for posting it and twoeleven99 for alerting me to this)
Happy Updating!

you can update even if you are rooted you cant update only when you modify the /system or some apps
went step by step through your guide and I still cannot update - the apply_patch_check still fails at DockProvider.apk - aside from reflashing the stock SBF, what do you recommend?
Try this
Try setting the phone to usb mass storage mode and replacing the files in the WebtopModBackup folder on the sd/media area with these: View attachment WebtopModBackup.zip
The files in the archive worked for me, not sure why it wouldn't work. If those don't work for you, please post the console log.

Thanks, but something appears to be totally screwed up on my DockProvider and DockService applications on Titanium Backup - they are listed at the bottom with grey slashes through them. The crazy part is.... it works with the webtop hack, but the update doesn't see the correct files, so something is obviously messed up.
Now, by putting the files from the WebtopModBackup on the phone, shouldn't that fix the issue? Then perform the steps in your text doc? I can't believe I'll have to SBF stock in order to fix the stupid DockProvider and DockService!!
What I meant was, replace the files in the WebtopModBackup folder with the stuff in the archive, then re-do the instruction in the text file.
I'm sorry but your instructions aren't working for me. I've followed your instructions very carefully but when I get to the command
cd /mnt/sdcard/WebtopModBackup
I get a directory not found error.
I can change to /mnt/sdcard but when I type 'ls' nothing appears. The directory is empty.
What am I doing wrong?
One thing I've noticed is that when I enter the 'adb.exe shell ./data/local/tmp/psneuter' command, the phone appears to dismount and remount and then when I go into the shell the '/mnt/sdcard' directory is empty.
Yeah I'm also having that problem....I'm trying to push the backup files into the correct folder. However, when I get a read-only error, so from what I read I'm supposed to reboot into recovery mode. When I try to do this the recovery console says e: can't open/cache/recovery/command and I can't connect to my phone. Any help?
To start I want to say Thank you to the OP for posting this. But there are a few errors, so I hope I can help.
To anyone having issues with this, there are a few things that you must have to make this work.
Note this only works for AT&T Atrix as I do not have a Bell Atrix
#1; THE 1st PART DOES NOT WORK if you performed the update. You should be rooted. You can check to see if you updated by pressing menu --> settings --> about phone and your Build version says something like OLYFR_U4_1.5.7 it will not work, you need to skip down to my next post of my coding since you should already be rooted. The 1st part of this uses the method that made rooting possible, since that was removed with the update, it no longer applies. So if you are updated, you should already be rooted and can skip a few steps
#2; You must have a folder called WebTopModBackup with the .bak files in it on the internal memory (not your memory card but the fake internal one). Open the app called Files, select Internal phone storage, select the WebTopModBackup folder and make sure you see the following files, if not you need to get them
Code:
DockProvider.apk.bak
DockProvider.odex.bak
DockService.apk.bak
DockService.odex.bak
PortalApp.apk.bak
PortalApp.odex.bak
#3; Do not mount your sdcard. When you plug in your USB cable to the compter, pull down the drop menu, select the USB connection and make sure None is selected; then press ok. If one of the other options are selected, select None press ok and wait for 30 seconds for the internal and external cards to mount. @Phazoni more than likely this is your issue
#4; USB debugging must be turned on. Press menu --> settings --> applications --> development --> and check USB debugging if not checked
#5; Make sure you have at least 50% battery, just in case
#6; During the steps you mount (make it editable) the /system folder where the files are, if you get a read-only error you did not do step
mount -o rw,remount /dev/block/mmcblk0p12 /system
correctly or your phone is somehow not rooted.
Click to expand...
Click to collapse
Ok now let's look at the code in the OP
Code:
adb.exe push psneuter /data/local/tmp
adb.exe shell chmod 755 /data/local/tmp/psneuter
adb.exe shell ./data/local/tmp/psneuter
adb.exe shell
adb.exe push is the command to copy a file to your phone; so we are making a copy of psneuter and putting it on the phone.
adb.exe shell chmod 755 this gives premission to the phone to use the psneuter file
adb.exe shell ./ this makes the psneuter file run and creates a fake root
adb.exe shell this should really be typed as adb shell but whatever. This takes you into the phone's system to edit the files. While in adb, the line should start with a # if it is a $ then psneuter did not work. Just to try, type su and see if the $ changes to a # if it does continue
Code:
cd /mnt/sdcard/WebtopModBackup
This command takes you to the location of your backup, remeber step 2 & 3, if this folder is empty and you cannot get to it, you have an issue there
Code:
mv DockProvider.apk.bak DockProvider.apk
mv DockProvider.odex.bak DockProvider.odex
mv DockService.apk.bak DockService.apk
mv DockService.odex.bak DockService.odex
mv PortalApp.apk.bak PortalApp.apk
mv PortalApp.odex.bak PortalApp.odex
Personally this is not the best way to do this (rename the files by making copies and then making more copies), but not my code. The mv command moves a file. In this case you are only using it to rename the files removing the .bak from the end. See my code at the bottom
Code:
mount -o rw,remount /dev/block/mmcblk0p12 /system
This mounts the /system folder so you can edit the system files
Code:
cp DockProvider.apk /system/app/
cp DockProvider.odex /system/app/
cp DockService.apk /system/app/
cp DockService.odex /system/app/
cp PortalApp.apk /system/app/
cp PortalApp.odex /system/app/
This code copies the files into the original locations as the correct name. This assumes you are still in the folder where the backups are. If this fails, the /system folder is not mounted, the files are missing or you are in a different folder. This is also missing the chmod /system/app/* coding. I will cover that below
Code:
rm /data/dalvik-cache/[email protected]*.dex
rm /data/dalvik-cache/[email protected]*.dex
rm /data/dalvik-cache/[email protected]*.odex
rm /data/dalvik-cache/[email protected]*.odex
rm is the command to remove/delete a file, running these 4 commands will remove the system cache and will most likely cause your phone to reboot before the next step; that is ok.
Code:
reboot now
This reboots the phone and removes the temp root.

Click to collapse
NOW for my recommended coding
After you follow my 6 steps above do the following
#1. on your compter press start --> run --> Type cmd this will open the command prompt for windows. Then navigate to the folder where the original WebTopMod files are located.
#2a. If are rooted jump down to step 4
#2. If you are not rooted and have not updated your phone type the following letter for letter
Code:
adb push psneuter /data/local/tmp
adb shell
You will now be in the ADB shell.
#3. You should see a $ so type the following
Code:
chmod 755 /data/local/tmp/psneuter
./data/local/tmp/psneuter
#4 This will kick you out of ADB, wait for it and when it does count to 30 for adb to reset. Now type the following:
Code:
adb shell
#5. You should see the # sign, if you see $ type su to change it since you should be rooted either by rooting the phone or using steps 1-3 above for pre-update.
Code:
mount -o rw,remount /dev/block/mmcblk0p12 /system
cp /mnt/sdcard/WebtopModBackupDockProvider.apk.bak /system/app/DockProvider.apk
cp /mnt/sdcard/WebtopModBackupDockProvider.odex.bak /system/app/DockProvider.odex
cp /mnt/sdcard/WebtopModBackupDockService.apk.bak /system/app/DockService.apk
cp /mnt/sdcard/WebtopModBackupDockService.odex.bak /system/app/DockService.odex
cp /mnt/sdcard/WebtopModBackupPortalApp.apk.bak /system/app/PortalApp.apk
cp /mnt/sdcard/WebtopModBackupPortalApp.odex.bak /system/app/PortalApp.odex
chmod 644 /system/app/*
rm /data/dalvik-cache/[email protected]*.dex
rm /data/dalvik-cache/[email protected]*.dex
rm /data/dalvik-cache/[email protected]*.odex
rm /data/dalvik-cache/[email protected]*.odex
reboot now
This
1. mounts the /system folder so you can replace the files then
2. renames nd copies the back-up files to the original locations in one step
3. Then the chmod 644 command sets the correct premissions for the files so they work,
4. clears the cache and
5. reboots the phone.

After making custom Boot Animation, Black Screen [FIXED]

I WROTE THE FOLLOWING WHILE TRYING TO TROUBLESHOOT/DOCUMENT MY OWN STEPS BUT I HAVE FOUND A SOLUTION. I HAVE POSTED THIS IN CASE SOMEONE ELSE MAY FIND THE INFORMATION USEFUL.
Is that appropriate? Move/delete this if you see fit.
I have an AT&T Moto X running 4.2.2 rooted with PwnMyMoto. Since it is with ATT, it has a locked bootloader.
[PROBLEM]
After putting a custom bootanimation.zip in the /system/media directory, device boots/"works" but display is black.
[HOW IT HAPPENED]
Using ES File Explorer, I turned on the /system r/w, copied the bootanimation.zip from the (internal) sdcard, and then overwrote the original boot animation (I do have a backup).
However, after booting the phone now, there is only a black screen. It seems to be working, there's just nothing displayed.
[WHAT I CAN DO/HAVE DONE]
ADB debugging has already been enabled
ADB shell has already been granted superuser permissions (Using SuperSU, unsure if solution works if this hasn't been done?)
It vibrates sometimes as though I have an email, notification, or whatever
I can access storage with usb cable,
adb get-state returns device,
I CAN get into fastboot (screen displays normally here), however PwnMyMoto overwrites recovery,
when rebooting the phone, the motorola power down animation is displayed
I tried to put back the original with
adb push bootanimation.zip /system/media
but get 'permission denied' (you may be able to use method this on a different device/carrier/ROM)
adb shell getprop ro.boot.write_protect returns 0
in adb shell
mv /sdcard/download/bootanimation.zip /system/media/ returns failed - cross-device link (googled this, seems normal, but I'm unsure how else to copy it back)
su
mount -o remount,rw /system
doesn't return anything but I am unsure where to go from there.
cannot run adb as root, as the phone is not a dev model
[RELATED POSTS]
http://forum.xda-developers.com/showthread.php?t=2249659
[HOW I FIXED IT]
start adb
ensure that 'adb shell getprop ro.boot.write_protect' returns 0 (if not, reboot into recovery)
start phone in recovery mode with
adb reboot recovery
then
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
mount -o remount,rw /system (not sure which one of these ended up being 'correct' but it didn't hurt to do both)
cp /sdcard/download/bootanimation.zip /system/media/ (copy <src> <dest>, src is wherever the backup zip is located, if you are unsure of where the files are, use the 'ls' command to navigate the directories)
adb reboot
After doing this, the screen started displaying as normal.
Apologies for the lack of technicality, not much a dev myself. Just glad to have it working again.

I wrote down the steps I took to fix it at the end of the post. You'll have to restore the old boot animation file with ADB. Hopefully, ADB shell was already given root permissions on your phone, otherwise I'd be unsure of how to fix it.

If you're unsure how to start ADB, I'd think that you've never used it before, and in that case I'd be entirely unsure if that method would work.
That said, you should find adb.exe in the sdk/platform-tools folder. If you shift+right-click this folder you can quickly open a command prompt there to start using the commands (each line in the instructions is a separate command). If you're unsure how exactly to use adb, I'm sure there are youtube videos or other forum posts documenting the basics (try searching for beginner's guide to adb on xda).
YES!!!
