Keeps downloading image even when already downloaded

My girlfriend has downloaded an image from internet by long pressing the image and then selecting "save image" on her Wildfire S with stock Android 2.3.3.
The problem is that the phone keeps downloading this image over and over again even when it is already downloaded. It tries to download the image about every sync action for over a week already.
Before i just delete the whole history i thought maybe someone here knows the answer to this problem, so she can avoid it in the future.
Many thanks for your help!

Hi, I have similar problem, but with applications. Sometimes phone starts downloading already installed app. Even if I set all apps to manual update only.
This behavior is really killing my data plan limit!
My friend with the same phone has this problem too.
Anyone have similar problem or solution to fix it?

The same with me. Does anybody know how to fix it?

Same here. Must be something specific to the wildfire S

I've got the same issue. I guess it'll go away once I can flash a CyanogenMod or MIUI ROM

Works for me alright

It's worth completely removing the offending application and then reinstalling it. I had the download issue with 'LED Light'. Removed it and reinstalled it and problem resolved.
I now have the same issue with another appl - will try the same solutoin
It seems to happen when you do an update which is interrupted partway

We ported this rom on the Aria and had the same issue. I replaced the DownloadProvider.apk and DownloadProviderUI.apk with the ones in CM7 and it now works fine.

Can you offer this for us?

Here are the apps. You need to delete them from your current rom and replace them for these.

How do I delete them without root access? My Wildfire S is not and can not be rooted at the moment

I assumed the Wildfire S was "rootable". That's a very goo question. You can try something but I have absolutely no guaranties it is going to work because I personally never tried it. Either way, it's your call.
**Make sure you back-up your phone to the Google Server because this will wipe all the data in your phone.**
1- Run the RUU for your phone. This will extract the rom to the temp folder of your computer. For me it's under C:\Documents and Settings\username\Local Settings\Temp\. An easy way to find it is to clear that folder prior to running the RUU. This way, it should be the only thing in there.
2- Enter the folder and look for a zip file called rom.zip
3- Open the zip file using 7-zip or Winzip. DO NO EXTRACT THE FILES ON YOUR COMPUTER TO REPACKAGE AFTER. THIS WILL SCREW UP THE ROM. You really want to make any addition or subtraction from the archiving utility.
4- Extract the system.img file. Now the challenge is to find a way to edit the content of that file. I personally have no idea how to but I'm sure there must be some tools to do that.
5- Once you've managed to open the .img file, under system/app, there should be DownloadProvider.apk and DownloadProviderUI.apk. Delete those and replace them with the ones I sent in my previous post.
6- Close the .img file.
7- From 7-zip, delete the system.img file and replace it with the one you edited.
8- Close 7-zip and follow the rest of the instructions from the RUU.
Again, no idea if any of this will work because I've never been in the situation to make changes on an unrooted phone. Your biggest challenge is step 4. If you cannot get in that .img file, then I guess you'll have to wait to get root access to your phone. My guess is that it shouldn't be too long since HTC agreed to unlock the HBoot.
Good Luck!

And is it possible to change this files in a "running" ROM Image (rooted, without flashing)?

I think so. Like I said, I never tried it so it's all speculation here. How about you try to install the apk on top of the ones you currently have, i.e. without deleting them? You do have the ablility to install from Unknown Sources correct?

Yes i have. But I'm new to Android, so I want to be careful.
I replaced both in system\app folder (without installing) and after that my market doesn't work anymore.
So I had to flash my ROM cause the Backup files didn't work too.
Was a lot of work, making all new (but at least Titanium Backup works ).
Maybe somebody other knows more?

I am a bit confused here. What do you mean by you replaced in system/app without installing? Also,you said you used Titanium Backup. I thought this app only worked on rooted phone
Unfortunately, I cannot be of much help because I really have an Aria with a ported rom from Wildfire S. I personally fixed the download issue by deleting and reinstalling these apps, but in reality, I have no idea if that would work on the actual Wildfire S. Sorry that I cannot be of any help.

My phone is rooted.
I mean I changed the apk files in folder system/app with those from you (using Root Explorer). Before I deleted them I made a backup of the original ones.

Ok, so try this then. Delete the apk and don't replace them. Flash the Rom and boot the phone. Then install the apk from ur original Rom, i.e. not the ones I provided, but the ones u originally deleted.

I already flashed my Phone with original ROM and it works again, but the bug is again there.
The point is, I dont want to flash my ROM every week so I hoped there is a solution to change without flashing again.
Otherwise I will wait, my there will be a fix from HTC.
But I wanna say thank you, for your help and your patience with me!

I'm with you on the flashing. I'm not sure HTC will release a fix for this though. However, what u can do is return ur phone and get another one. It seems not everybody has this issue. I'm personally glad I could resolve it on my phone.
Good luck!

Remove Bloatware from T-Mobile Note 2

I searched many various sites including this one to try and find the best and safest way to uninstall bloatware. I tried Titanium Pro and when I tried to Backup/Restore and selected an app to delete it then rebooted my Note 2. I looked back into B/R and found the item was still there. There was a message indicating that it may take 2 or 3 reboots to complete the uninstall.
I am looking for an app that will run and unistall all bloatware that is safe to use or gives you the option to select apps to unistall. I did download one which looked very good and even listed the apps it would uninstall. It was SuperNote2 DeBloatware which was a zip file. It would not unzip and I could not get it to unzip after numerous downloads.
Anyone have a suggestion? Thanks in advance.

I did find that posting yesterday and downloaded mrRobinson_Note_II_De_Bloater.v1.00.zip to my PC. When I unzipped this file I saw folders:
apps
assets
meta-inf
These folders dated back to 2/28/2008. So, I was very unsure to use this.
When I opened:
apps it contained: GoogleQuickSearchBox.apk
Assets contained; common, fonts, icons, langs and themes.
Meta-inf contained: Com, Cert, Cert and manifest.
This just did not look right for what this was suppose to do. So, I left it.
Your opinion?

You are using a custom recovery, aren't you? CWM or TWRP ... Just follow the instructions in the 1st post. Boot into recovery and select that file and click custom and either run the program or just look through the files that you can remove and exit if you don't want to use the program.
Or, you could just install a custom ROM and not have to worry about this?

That thread is quite old and if you noticed, somewhat inactive with some issues reported. I always use Titanium Backup to "freeze" apps - this usually removes them from being active (and thus saving CPU and battery) but they still remain should you want them. It's a simple and painless process as you are not really deleting them and they do not use much memory anyway.
Here's a great list for the Samsung Galaxy line of devices from Android Forums: http://androidforums.com/metropcs-cdma-galaxy-s3-all-things-root/695070-safe-apps-remove.html

I honestly suggest using a custom rom instead... there are lists out there of apps to remove but it is more based on whats safe to remove vs not safe... ultimately its all user dependant (ie what apps do you use vs what someone else uses)... for me, I love to just install either CM (as reliable and "bare" as any of the roms come) or Jedi roms via aroma (if you still want to hang on to the TouchWiz side of things)... Aroma installs allow you to choose the bloatware you want to have and disregard the ones you dont want... there are tons of tutorials online that take you step by step... make sure you follow the directions (completely) and happy flashing!!

Dont know if you are still in need of help trying to figure out how to flash roms but, you would first need to install a custom recovery. The two major recoveries are TWRP and CWM. They're on par. I used CWM for years but switched to TWRP. From there you first want to make a backup of your original rom and flash as many roms you want to try out. If you dont like the rom, just restore. I dont know how familiar you are with flashing roms but it takes like one try and you pretty much do the same thing over and over.

MTP USB Device?
I thought I was doing great after uninstalling bloatware. However, when I tried to connect my Note 2 to my PC via USB I received the error that MTP USB Device driver could not be loaded. Apparently I must have uninstalled something on my Note 2 that is not allowing me to connect to the PC via USB. I have been searching all day, downloading various Driver apps to no avail. I even downloaded and installed Samsung Drivers which also did not work.
It never ends. Fix one thing and then another pops up. LOL
What else can I say except - H-E-L-P.
I still can use my USB plug from NOTE 2 to my Flash Drive to get stuff transfered to/from Note2/PC.

ps this is why its so important to make a backup in twrp or cwm....google it or find it here! they also call it a nandroid backup...VERY IMPORTANT for issues like this. As previsouly stated you should be able to put the stock rom (check out sammobile's web page for official f.w) on the sd card and from there you can boot into recovery mode and install it from there. I believe. If that don't work look into mobile odin which I have never used. sorry for he typos lazy!

I just rooted my girlfriend's Reef in about 2 mins. I haven't yet messed with roms or recoveries yet, however, that will be a project for tomorrow. It's a pretty simple procedure, make sure your phone is set to allow apps from unknown sources, Google "Framaroot 1.4.1" from your phone's browser, then download the apk. Also make sure that if you have anti-virus on your phone, clear the defaults, as the apk will not install if you have it set to autoscan before install. Click the download in the notification bar when it is done, then install with "package installer". When done, open the program, install with "Superuser" (which is the default option at the top). My phone rooted with the "Gandalf" exploit. Reboot your device. Verify that "Superuser" shows in the app drawer, I also verify root with "Root Checker" by joeykrim.

Security update with root

So, I'm new to rooting and this is my first Nexus device.
I'm loving it and all the options but now I'm getting a notification to update.
I see all the forums about hooking it up to a computer and using commands to do it all and then rerooting.
I was looking for an easier way.
I bought a Nexus 5 to play with because I liked this one so much and when OTAs came up, it would let me download them and reboot into CWM recovery and ask if I want to flash the ZIP.
This one just boots into TWRP (No CWM for 5x) and does nothing.
I found the update as a zip here:
<https://gist.github.com/jduck/744a6c8a9042e9c792b7>
My question is: can I just download it and use TWRP to flash it or is the sequence of commands on a computer the only way to do it?
Thank you in advance for your help and I apologize for my ignorance.
Gotta start somewhere though, right?

Hi !
I personnaly use NRT from Wugfresh for my Nexus 5x and my Nexus 7 2013, both rooted.
In "model type", select Nexus 5x and your build.
In "Restore/upgrade/downgrade", select "device is on/normal", then click "Flash stock+ unroot".
Select the build you want to install, it can dl and extract it for you, and select "No Wipe Mode" in order to keep your data and apps. (don't try to put your ota file here)
Go through the steps, and in the end, hit "Root" to root again.
I know there are others methods to apply just the OTA with command lines, but I never did it cause I never took the time to learn. I should do it, maybe it's faster with command lines.
Anyway this works, even if it takes a little time, and it is kind of automatic. But I strongly recommend you try both method to find what suits you most. Or wait for someone else to reply so you'll have more points of view !
Have fun with your N5x !

I like the idea of that.
Does it reinstall the superuser app automatically?
If so, which one?
And does it redo custom recovery?
And which one for that?
Sorry for all the questions but I purchased SuperSU and I don't want it to automatically download a different one and have to go through the steps to change a superuser app.

Are you using flashfire v0.28?
Xposed modifies the system so while you maybe able to get the ota it can prevent you from installing them even with flashfire.
Go to the flashfire thread and see if this is a problem with the app or because or xposed (most likely answer).
Otherwise find the ota threads and see if you can flash it through recovery (not the N version)

Yeah, it's that version of Flashfire.
I have the update zip but I'm afraid to just flash it.

Worth it just to add it to the queue to save the time.
Everything else seems to be working fine thus far.
A few settings are changed (TinyCore was turned off and hidden apps in Smart Launcher 3 were unhidden) but that's nothing big.

That is the same manipulation I explained in post 2, but with Flashfire, without using a computer. And full automated, where with nrt you have to factory reset and root later. I'll try it next time ! And yeah, the version of SuperSu is always the latest, and if it is not, it will update via play store (I bought it as well ^^)

This one didn't unroot. Just uninstalled Xposed. Kept all my data and stuff. Apps stayed signed in even. I was afraid because I heard "factory reset" in yours. Or something to that nature. The only thing I'm having problems with now is Tapatalk told me to check my adblock settings and won't load anything. I'll have to look up what's wrong with it. Other than that, it's doing all right.

You are right and wrong, it unroots but reroots in the process. Same I did when I used nrt. And as i didn't wipe data, apps stayed sign in as Well.
But i tried flashfire on my nexus 7 and I it is way more useful and faster than nrt. I am adopting it !

Can you access TWRP? If so, just download and install the Xposed framework disabler/uninstaller (available in the official Xposed thread). In my experience on various devices, this is the best universal method to deal with offending modules (incompatible or misconfigured). Otherwise, you can use the file manager or terminal in TWRP, if that's your preference, and if you know exactly what you want to do...
