[Q] how can i restore system apk.

First off I'd like to start off by saying that I am kind of an idiot...with that said; I like to mess around with important files on my device(Acer a100) even though I have absolutely no clue what I'm doing.
Using titanium backup I uninstalled that download system apk. The one with the green icon and the white arrow pointing down. Now when I try to restore it through tit. Backup it will just freeze and keep saying that it is restoring and I have to finally force close titanium. I have also tried messing around with permissions in root explorer, fixing permissions in rom manager, navigating to system/app and installing it manually through a file explorer( get message install fail), and hard resetting.
The main problem is that everything I download will show in my notification bar and after I close/exit them they come back 5-30 min later. If I click on the download in my notification(not on the x) then my notification bar just closes. I can kinda fix this by turning my notifications off or cleaning data/cache on ?download storage? Apk/app.
Does anyone know of an easy fix for restoring this system apk. For there are no custom roms or recovery sources for this device that I have seen yet.
Thank-you, Robb

PM me with your email address, I'll email you the apk from my A100, I'm still running the stock rom that I pulled it out of the box with.
You can download it straight to your tab from your email, beforee you do, get a file manager (like es file manager) from the market. You will be able to get to your downloads folder from there and install it.
ummmmm............ could you repeat that?

He's got Root Explorer, that should do the trick.
To the OP: You are mounting the system partition R/W in Root Explorer when you try this, aren't you? Hate to ask a dumb question but.....

Yes I am hitting that button up top on root explorer changing it from r/w to r/o but I think some how I just got the wrong apk....after titanium wouldn't restore it I think I remember copying apk. From my phone (g2x) and attempting to restore those...dumb, I know I might of tried changing the names of the apk. Too,..like I say I f*** with s*** I have no business Fu****** with. I will p.m. my email now maybe I can get a screen shot of the system files if anyone feels up to it, so I can cross check proper name and sizes

How about just reinstalling the 3.2.1 update that is in the developer section. There should be no reason to factory reset since it is the same version. I have soft bricked mine a few times and I have just did the update again.
I even upgraded from whatever version the device shipped with to 3.2.1 without wiping the data.

A100 development section??? I see three a100 recovery downloads and one a101 recovery in our development section but when I download them i t says they were corrupted...if those are what your talking about...which one exactly should I use and what do I do with the file after words???
----sorry two that say a101 and two a100
So should I use file Id # 115,116,117,or 109

Use the one in this post. It is already decrypted. The ones in the frist post need to be decrypted using the Acer decryption tool. I have used the one I linked to probably 20 times. Once you run the update you will have to re-root the tablet.

thank-you all..recovered and fixed!!!
I was able to fix my problem by using the recovery update zips. But I want to thank everyone that helped, and remind people from experience to freeze unwanted system apps instead of uninstlling in titanium backup.u
Very important advice also is to search and read before starting new posts. I could have saved some time and headache just by doing that...the answers were just a couple paragraphs away the whole time.

[Q] "No SD Card" error in Chrome

I updated my Vzw GNex to the vzw 4.2.2 ota this afternoon. Everything works fine except when I try to download something from chrome I get a message saying "No SD card" when I click a download link. I can access the sd card just fine with rootexplorer and the stock browser downloads things just fine. I tried clearing cache and data for chrome and even uninstalled and reinstalled it. Anyone else having this issue? Is there a way to fix it?

I am seeing the same issue on my GNex running AOKP mr-1 build 6. I have not found a fix yet.
Of note: I do NOT have this issue on my Xoom running 4.2.2 [baked_wingray_bb-8]

Try making a copy of your sdcard and factory resetting, then copy all the files over using MTP, not ADB.
I get that if i copy files over using ADB.

Mach - Thank you for your response. I have to ask though, is there any other way?
Per your recommendation I began to copy my sdcard but quickly realized that given the amount of data on my phone this would be painful using standard methods. Windows [7] was reporting no progress and seemed as if it was going to take forever to copy the contents and applications like RichCopy and TeraCopy do not see MTP devices
In the end, I simply used 'adb pull' to copy the contents. So, while it's good that I have a copy, I'm not sure how I plan to restore the copy after a factory reset without using 'adb push', which you said sometimes causes the issue. I always thought that using 'adb' was considered more reliable than the MTP interface.
Recommendations?
Thank you.

Hi, if you are running Xprivacy you should check if you have denied the 'Storage' permission for Google Chrome. That was the problem in my case.. :silly:

Hi, sorry it took a long time to reply, I just saw it. Xprivacy is an Xposed mod to manage the permissions for each app. If you haven't installed it then it is not causing you any problems!

In regards to my aforementioned issue.
"Cannot download due to SD card missing" Error.
Simply open a terminal emulator and type in the following.
su
restorecon -FR /data/media/0
Reboot and it should work thereafter.
wrong thread, genius, sorry.
(that is the solution though )

I had the problem with my Galaxy S3 running Lineage OS 14.1. This helped, Thanks!

I have just found another and simply solution in no rooted devices. Just open file manager and rename 'Download' folder to 'Download2' and then the system will automatically recreate 'Download' folder. Now, you are able to download.

[Q] Help me with media issue?

So i was on g2 apps v5.5 rom for some time when all of a sudden my media stopped scanning, i wasnt sure why, rescan media apps werent working either, so i decided to flash a new rom and i chose candykat, since then all of my files that i used to have, pictures, videos, etc have completely vanished. i cant locate the files in 7 zipper, es file explorer, and media scan apps still bring me nothing. Yet my internal storage still has the same amount of space used that it did before, and also when i go into CWM and choose install a zip it shows all the folders and things that i am missing, but that is the only place i see the folders but i dont have access to my files from cwm. Also i have noticed that when i am on 7zipper looking through files my internal storage says storage/emoulated/0 and i have no idea what the emulated is about, if anyone has any info or knows what im talking about please to help, Im not too great with phone stuff but i am okay, so if anyone has any simplified steps to give me on how to fix this issue it would be appriciated, thank you.

No answers anyone?

Just do some searching mate. And use ROOT EXPLORER and give it access.

The way Kitkat makes the "SDcard"/"Internal Storage" directory is different from how it was on Jelly bean. <--EDIT: By this, I mean that the directory path is different.
The card is reading that X amount of data is on the card, yet you can't see it because your files are technically still there, but under the old directory path.
There are a couple of ways to fix this, but the EASIEST (IMO) way is to first restore a JB Nandroid backup (you can backup your KK ROM first if desired). First thing you'll notice is that the files will be there again. Now, plug your phone into your computer and copy all the files to it.
Reboot into recovery and format the internal SD. It's best to do it from within recovery, because otherwise, JB will just recreate the JB file structure and immediately start saving stuff to it. So when you get to KK, there will once again be the old structure hidden and with some files taking up space.
Now either reflash your KK rom or restore your KK backup.
Boot it up and copy your files back to the phone.
*I ran into this same issue after flashing KK for the first time. This is the exact process I did to resolve it.
Another way is to use a root file browser and locate the old directory and copy everything over to the new one. However, I think this might take quite a long time since the phone can do this only so fast.

[Q] Unable to connect to PC properly after rooting

Hello,
I have had my HTC One M8 for a while now but I wasn't really happy with the soundquality while playing through my headphones, so I looked for ways to improve it. I found a few methods and finally decided to give it a try. These methods require a root so yesterday I have rooted my phone for the first time. Unfortunately I am experiencing some problems now.
The rooting process went without too much trouble. I used hasoon2000's toolkit and have TWRP version 2.7.0.2 installed as recovery and used it to install the provided SuperSU, which didn't work at first. On the forums I found a newer version and installed that one, updated it and got it to work.
Now this is where I think I messed up: I read somewhere that when rooted, you are able to delete pre-installed apps from the phone. I downloaded SD maid and deleted Kid Mode, Zoe and 7digital. When I deleted Kid Mode I got an error saying it has crashed. I tapped away the error but from this point I couldn't go back to my homescreen anymore because my launcher kept crashing (com.htc.launcher crashed). I rebooted the phone and the launcher worked again, but the phone still seemed to be buggy.
After this I tried to install the snapdragon audio+ (this was my first choice for an equalizer). I downloaded the apk and moved it to the system folder using ES file manager. I installed but when I tried to use it (through settings in google play music app) my phone would crash. I uninstalled it and tried again, but when I tried to move the apk to the system map like before, my phone would crash everytime. I then found out the file I used doesn't work for lollipop so I figured that's what caused the crashes.
My next move was to try and install viper4android. I downloaded it from the Play Store and opened it. It told me it needed an installation of BusyBox so I downloaded that too. But when I opened the BusyBox app and clicked install my phone would crash again. After some searching I found that the HTC One M8 requires BusyBox to be flashed manually so I downloaded the file but when I tried to load it onto my phone I noticed this wasn't possible anymore.
Now when I connect my phone to my PC the PC recognizes it, but when I open the map in Windows Explorer it only shows three maps; .showme, _nero_sync and Ringtones. I know there should be more as they were there before. It also shows my phone's capacity as a total of 10GB (shouldn't this be 16GB?). Also when I try to connect it with Sync Manager it gives me an error everytime I reconnect the phone; Device unavailable. Please reconnect your device [4].
I have tried to reset the phone through settings, wipe with TWRP and fix permissions with TWRP. I also tried reinstalling Sync Manager and the drivers on my PC. What I'm thinking now is I maybe have done something wrong in the ES file explorer that would make the folders unaccessible.
My phone is running stock android 5.0.1 and my PC Windows 7 64-bit.
I hope someone can help me, Thanks.
P.S: Sorry for the long post, I figured I'd give as much info as possible.

@Steef076 First update recovery to the latest one (2.8.6.0)
Second if you go and delete vital or integrated parts of the stock rom you will get a lot of bugs. Third, viper4android requires to write system and you can't write system with the stock kernel, you need an unsecured kernel or unsecure it yourself.
10GB is right since 6 is eaten by android. At this point I would just revert to a backup or install any custom rom around here. Most are close to stock and with no bloatware and come with root. You can even clean them further using a tool called ROM Cleaner. It will most likely solve all your problems

Did the deleted system apps reappear after reboot, or do they remain "uninstalled"? If the system is write protected like TempestZ states, any deleted system apps should reappear after a reboot.
Revert your nandroid to restore the system apps. And you didn't make a nandroid, you really should before making any system modifications for the very reason that it allows you to revert if you run into problems.
Another good practice, is if you don't know what effect deleting a system app will have (such as "safe to delete" lists that can sometimes be found on XDA) you should first freeze the app with Titanium Backup. If freezing doesn't cause any issues, then go ahead and delete. If you do have issues, just unfreeze the app.

No, Windows will never show 16 GB. It only shows "internal storage" partition, or the user accessible portion of the storage. A good chunk is reserved for the OS.
Does what is shown in Windows differ from what is shown in ES if you browse to internal storage?

Thanks for the replies. @TempestZ @redpoint73
First of all I managed to update twrp to 2.8.6.0 using adb/fastboot.
To answer your question @redpoint73 the system apps I had deleted indeed reappeared after reboot. Also I didn't make a nandroid before I deleted the files, as I did not even know this was possible. Now I have made a nandroid of my stock ROM that is working decently, except for the TV app keeps crashing (I'm not opening it) and the connection to the PC is not working properly (not sure if this is ROM based?). I have noticed when the phone is in recovery I CAN see the folders through windows explorer. HTC sync manager still doesn't find it though. I am working on finding a proper stock ROM or maybe flash a custom one to see if that will fix it.
I understand now that the OS is taking up the storage space. The space windows is showing is the same as ES file manager so I guess this is fine.

HTC Sync is a hot mess. It often causes more troubles than it solves.
One thing you can try (to see if it fixes the USB connectivity) is uninstall HTC Sync and all HTC drivers. Than connect the phone. Don't let it install HTC Sync. Go to Windows Device Manager, find the device. Then pick the option to manually select the drivers, and pick the generic "Android MTP device" (or something to that effect) drivers.
This doesn't work for everyone. But it worked for me to be able to "see" the internal storage of my M8 on my home PC (Win 7). Annoyingly, it seems to vary from one PC to another. My work laptop (also Win 7) works fine with HTC Sync.

Steef076 said:
So if I understand correctly, 'version-main' is the same as 'firmware' and 'software number' (found in settings)? If so, my current firmware seems to be 4.19.114.2.
Now, what you're saying is I should do an OTA but this isn't possible because I have a custom recovery right?
Also, when I want to flash stock rom and stock recovery or do a nand don't I need the files that fit my cidnum? How would your file work for me?

If yours already on 4.19.114.2 then no need to do OTA as that the latest.
and my backup will bring back your device back to stock as you first bought it when restore with a full wipe.
Try to solve your problem first, only when you really need the backup then only I will upload ... let me know

Hello, sorry for the late reply.
I have decided to give a custom ROM a try. I now have ARHD 41.0 installed and it seems this took care of my problems. All the maps are showing in windows explorer and HTC sync manager is connecting properly with my phone again. Also no more crashing apps. Your backup would still be of much use for me as I am not sure I want to stick with a custom ROM and therefore would like to have a stock ROM backup.
Thanks in advance.
