ROM: |3/24/2012| |ReloadedROM™| |CM9 Reloaded| |Kindle Fire| [CM9]
This problem also occured on Energy Kang.
Basically, any app that I leave on the sd card before I reboot will be gone after it. App Manager says "couldn't find app," the application size is changed to 0.00bytes, and the application names are the long com.etc ones. The icon remains on the homescreen but gives "App not Installed."
I honestly don't know what's going on. It's driving me crazy. Does anyone have any suggestions? These problems only happen on the ICS based roms. MIUI and CM7 have no issues with it, if that's any hint. I also had to flash ICS Google Apps for the ICS roms.
Google searching and attempting the fixes offered no solution. IT's said that this occurs when you have 50+ applications on the sdcard, but I can't even get ONE to stay on there, so how could I have 50? They just keep disappearing.
You're not the only person it happens to, and it seems to be a known issue on most ICS ROMs. If you really need the extra space for applications, I guess you could repartition the KF...
I don't need to fix it, but curiosity is getting the best of me. I just want to know why it's happening. Any hints would be welcomed, too.
I know that I can just move the apps to the system, by the way. I'm wondering if it's trying to put the applications in the wrong place...Hmm.
I recently rooted/installed CleanROM for my S4, but now I have some basic questions regarding what actually happened in the process and how I could improve it. (First smartphone, first Android).
1. Is flashing the exact equivalent of installing a kernel/ROM/app in a recovery like TeamWin that is zipped in an SD card? All I did was select my zipped file and install--the guide says to use GooManager but I never used it. Also, does updating TWRP, kernel, or ROM (same application/kernel/ROM, but newer version) require that you delete the old ZIP, copy over the new ZIP, then install it? Is there a cleaner method (I feel that since we have to wipe to prevent old files from interfering with new ROM that maybe parts of the old version of a ROM may be redundant or may interfere with the new ROM?
2. Is there a way I can save the phone settings when dealing with one ROM and transferring these settings to another ROM? I really don't want to spend 20 minutes to go through all the settings and change it to my liking every time I install a new ROM.
3. With TWRP I could backup the entire ROM and also be able to install that backup ROM if I don't like the new ROM installed? What does Titanium Backup offer in regards to this aside from backing up app data and the ability freeze/uninstall system apps?
4. Does Titanium Backup leave any residual files? I see other apps designed to uninstall system apps and Titanium Backup seems like an all-in-one jack of all trades.
5. I thought I wiped everything and to me, that sounds like reformatting the entire drive. I only wiped system, boot, and data though (good enough for ROMs, according to what I've read). I was surprised when I saw my videos that I had already backed up to my PC accessible on the phone. Should I just wipe literally everything (I assume it would be cleaner) like cache, preload, EFS, modem, recovery, etc.? Will wiping literally everything be like reformatting my phone (since my phone was not reformatted because my personal videos was still there when I installed my custom ROM? If I were to install completely different ROMs cleanly and wanted to keep my personal files, I would only need to wipe system, data, and boot?
4. Do I have to use CASUAL again to install an updated TWRP?
5. Does backing up a ROM also backup its root? I'm going to assume this is a dumb question and the answer is no. I'm also guessing I have to block OTA updates from AT&T to ensure I keep my root. How would I go about doing this? Also, would my phone be "safe" if I stick to my ROM (no updates or anything) for 4+ years? I'm asking this as an extreme case because I feel like I'm missing out on AT&T security updates that could protect my phone and also I don't think the developer my ROM (CleanROM) will do frequent updates).
6. I had problems with my computer not being able to recognize my phone and my SD card in the phone after I wiped everything and before I installed a ROM. I literally had to take the SD card from the phone and use an SD card reader to transfer my custom ROM/loki then put it back into the phone. Was I missing a driver?
7. What are some must-have apps a newly rooted user would want?
8. I read that you only need 1 EFS backup and you don't need to back it up every time you are going to install a custom ROM. Can I get a confirmation?
9. What does Goo Manager do and would I want it?
10. Is it essential that I keep up to date with news about my custom ROM/phone to ensure my phone is secured?
**Not Root/ROM related--Is swiping an app away from the Recent Apps List (long-press home button) the equivalent of killing an app? I use the Recent Apps List often but I don't want to go about swiping apps away if means it is killing it, since I read that killing apps are bad and actually drains battery life. Also, is there a mod that lets you access the Recent Apps List by long-pressing the menu one? I only see a mod that kills the app if you long-press it.
Also, any ROMs you guys can recommend me that is like CleanROM? It has to be TW-based because I use multi-windows. Basically, I want a stable, popular (popular ones tend to be more frequently updated, which is important because there are often bugs in custom ROMs), and optimized/debloated ROM (as debloated as possible, I rather use my own large list of apps than pre-installed ones). I was looking at GoldenEye but I'm not sure.
Thanks. I'm hoping for many responses as I have more questions to ask but not a lot of free time (I will check back on this thread every several hours until there are no more responses on the thread.
Hey there! Here is my take on at least some of your questions. I am not a super pro, but I will try not to give you any wrong info.
1. The zip files that are still out on your SD card are just the install files for whatever you are flashing. They won't be cleaned up automatically and you will need to delete them yourself if you want them gone. That being said I would recommend leaving the previous version's zip out there in case you need to back out of the new version.
2. If by phone settings you mean all of the settings in the various option menus baked into the ROM it is best to redo those when switching between ROMs. Many ROMs add and take away options and add whole new option sections so you will want to go through those and set things to your liking. Another option is to use a launcher like Nova Launcher that lets you back up its settings and restore them which is a big chunk of the things I change when going to a new ROM. Some people may have a different opinion on this one.
3. Yes if you make a backup in a recovery like TWRP and then restore from it it will be like you never flashed the other ROM. Titanium backup does what you say and also can backup individual Apps themselves and restore them.
4. Once you have a recovery installed you should not have to go through the hoops you went through to get it there to update it. Check the thread for the recovery for upgrade instructions.
5. Your SD card will not be wiped when you wipe system or data. There is also the internal "sdcard" that if I recall is not wiped when you do a standard wipe which will keep things like pics and videos between flashes.
6. So you were trying to access the phone storage/SD card while it was in recovery? I have never had much luck with that. I always just make sure I have all of the files I will need to install the new ROM moved over before I wipe it. That being said if you have the right driver it might be possible.
7. Titanium Backup, a file explorer that can leverage Root access like Root Explorer, maybe something like Greenify (I think it takes Root). Other than that check out the thread in the Apps/Themes subforum where people list their top 5 apps.
8. Pass (but I think what you heard/read is right)
9. Goo Manager can let you know if there is updated version of your ROM or what other ROMs are available for your device and download them. It can also be used to install a recovery. Personally I don't use it and just check ROM threads for updates if the ROM doesn't offer OTA updates.
10. I rarely see mention of security fixes/features in custom ROMs so I don't think you need to stay on top of threads for that reason. With that said, if security is crazy super important to you then a custom ROM might not be your best bet. Even though source code is available for most if not all of them that doesn't mean someone has gone through the code looking for security flaws (or even malicious code).
11. You can test this yourself. Go into the "Apps" section of the options and look at what Apps are running then swipe one away and check again. Personally I would go ahead and swipe away Apps as needed since that is a core Android feature. I haven't seen a mod for what you are asking.
12. The other two TW-based ROMs I have used are Goldeneye and Alpha. Both are good, but I am using Alpha now due to its higher degree of customization. Goldeneye hasn't been updated in a month or so, Alpha is being updated regularly at the moment.

Nice post, very good help...serious...
Incredibly helpful, thanks. I will post more questions if I have here, kind of busy at the moment.
Question:
What is the best way to detect whether a third-party app has a keylogger? I read from an article that it is incredibly easy for someone to put a keylogger on an app. Is Avast Mobile Security and Antivirus capable/overkill for this job? Also, I was worried that Avast may actually be bad because it would deteriorate (wear and tear on the SSD of the phone) through all the scannings? Or am I completely wrong? If I am wrong, I'm guessing it's because an antivirus only reads your files and therefore does not wear down a SSD (I'm not even sure if this is right).

You can read a SSD all day long, that doesn't wear it out. Writing to a SSD will cause wear, not reading. I'm thinking that most antivirus apps can find that kind of stuff, but don't download from unknown sources or those you don't trust. Even Google Play has some shady stuff. I would recommend researching an app on Google if you have any doubts about it. I'm sure it can be done, but I really doubt any of your friends know how to reprogram one of your apps to have a keylogger, plus I wouldn't let them use my phone in the first place.
To answer your questions:
1. Antivirus doesn't wear anything out, it just puts load on your system.
2. Most antivirus apps should detect apps like the ones your talking about.

Thanks for the confirmation.
Another question for anyone:
Clean Master found the folder of an app that I installed on a precious ROM, so I not wipe the device cleanly. I though wiping system, boot, and data was enough--what was I missing, or should I have checked everything to be wiped on TeamWin Recovery?
Are you sure its not coming from your SD card?

First of all, thanks a lot to Cpasjuste for making the working gapps flashble zip, here's a link to that. I take no responsibility for doing this, all credit goes to Cpasjuste. Also I do not know a lot about deving myself but i've had two android devices before this and have been avid in modding them, just thought i'd put that out there.
So, first thing I did was get root, factory reset and get safestrap recovery. then I made a backup of my stock ROM, kept it on my kindle, and moved it to a safe spot in my computer (I recommend everyone does this, no matter if they choose to follow this setup or not.) I created a new ROM slot with default partitions, and restored my stock ROM to it (you do this in case any thing happens you have your stock ROM to fall back on). I tried flashing Cpasjuste's gapps rom, but for some reason there were multiple issues with it so instead, i restored to stock, on ROM slot 1, and flashed his gapps zip mentioned earlier. Rebooted and everything (well almost everything) worked perfectly. playstore works and only app that I have discovered to be incompatible is instagram for some reason, but i found a apk download online that installed perfectly to replace it. I installed a app from play store called recent apps quick button, which basically activates android's recent apps, then I installed a app from play store called Home2 shortcut. this lets me assign the resent apps quick button to double tapping the home button so now when i double tap the home button it brings me to recent apps. It's really nice since kindles default Rom doesn't have a recent apps button! Right now I am working on blocking updates from amazon to prevent losing root or bricking, using the tutorial found at the end of the root link. Let me know what you guys have done to make your kindle fire HDX experince better, or any questions you have.
Also, I forgot to mention that using the gapps flashable zip broke my amazon appstore and most amazon services, except video it seams like, but since we have safestrap recovery this isn't a big deal to me because i can always get it back, and im sure it will be fixed in future. Have fun and be safe while experimenting with your kindle.
I TAKE NO RESPONSIBILITY FOR DAMAGE DONE TO YOUR DEVICE, KNOW WHAT YOUR DOING BEFORE YOU DO IT!!!!!!!
Ah! Thats what I missed, I didnt realise I could use restore on a different ROM slot! Thanks for that, going to try it later!:good:

No problem! Also if I were you I would delete most of the user apps on your stock ROM, Idk if you did what I said and factory reset before you got safestrap (I would not try it if you already safestrap since you will lose safestrap and possible break you device!) but if you didnt I would just go back and delete most user apps and data off stock ROM and then redo the backup and restore with that. because you most likely wont be using the stock ROM (you don't want to alter it since you want to have a safe spot to restore to) you want it to take up as little storage as possible. My advice, pretend that you don't have root and don't do anything with it, like editing parts of system, or flashing mod packages, etc... (only exception is having super user and safe strap app installed.) Let me know if any part of this was to confusing. Hope this helped!
Haha, I saw your reply about 2 minutes after starting up the factory rest. I can, however, confirm that safestrap is still installed between the boot and IS load, so I'm actually in a perfect position. Have taken a new backup of pure stock rom!
Happy days!
I got a copy of my Stock ROM installed into ROM slot 1 and then added the gapps package, it worked beautifully!
I now have a tablet with all the google features on and have no issues so far.
except...
when I boot to ROM slot 1, I get a message saying "Kindle is Updating/Upgrading". It doesn't do anything and it only takes a few seconds before it gives up. I was just wondering if there was a way of getting rid of this??
As someone who hasn't had any prior experience with Android (although a fair share of experience with GNU/Linux), I appreciate a thread like this.
I also rooted the device (works well from GNU/Linux), installed SuperSU and some essential apps to make the stock OS usable (busybox and a terminal emulator, of course; and also a lightweight file browser that doesn't take much space and does exactly that, lets me browse local files). Then installed SafeStrap and backed everything up to both the Kindle and the PC (the backup is accessible via MTP, in the internal storage, so you can just connect the USB cable and copy the TWRP directory – at least in KDE).
Now I'm going to try the new AOSP ROM. Though since I'm new to the whole Android business, the partition sizes have me a bit confused. I'd want to have three slots – the stock ROM (obviously), the stock FireOS (one that I can modify) and AOSP. What partition sizes for the two slots would be the best, if it's the 16GB HDX? Also, say I download a PDF file; would both FireOS and AOSP see the file if I put it in internal storage, or would I have to manually copy it over to the other slot through my PC?
@GreatEmerald, whats AOSP? I'm thinking of playing around a bit more. I want to try out some more ROMs.
I put my first ROM slot (Stock with gapps added and amazon crap removed) on Flight Mode and now when I try and put it on wireless it restarts....

AOSP = Android Open Source Project
Many other devices have an AOSP build and is typically a very nice build to flash if you like the core android feel with some extra very nice features.

Yea, as mentioned, AOSP is a ROM for stock Android 4.2.2, pretty much the only big ROM available for the HDX7 right now: http://forum.xda-developers.com/showthread.php?t=2607185
It works pretty well as it is, I'm impressed it's as good already given how new the project is. Though it still has some issues for normal use. Aside from the bugs mentioned in the post, Chrome crashes as soon as it's launched (but you can use Firefox instead), as does the Kindle app (which is mainly what is stopping me from using it, because the point of a Kindle is the integration with Amazon services...). Also, the Facebook app fails to install for some reason.
Everything else I tried works fine. I installed F-Droid, a file manager, Busybox and a terminal, then the Amazon app and some of the Amazon cloud apps, and finally Skype. All of them work very nicely on AOSP. Even tested a video call on Skype and it worked without any problems (including the camera working correctly).
As someone new to Android and from a GNU/Linux background, I'm really happy that F-Droid exists. It's an app store/package manager that offers only free and open source software. For regular users that might sound as not a big deal, but actually filtering software by license is more powerful than one would think. You're guaranteed to have only apps that have no spyware and adware, because you can't hide them in open code. And those who make apps without publishing their code obviously have something to hide. So much like in GNU/Linux, the first place to check for new apps for me is F-Droid, and after that the main store of the OS (be it Google Play or Amazon Store), and only then 1Mobile market.
I still would like to know more about that partitioning, though. I figured out that the emulated SD card is shared between ROMs (I uploaded F-Droid to the Downloads directory on FireOS, and could see it on AOSP just as well), but I still don't know what exactly the two partitions you have to make to set up a ROM slot are and how much space should be allocated to them.

The system partition only needs to be as big as the Rom or backup you flash is, the data partition I typically make as big as possible (4000 mb) since this is what your Rom will consider internal storage. This is where apps and app data will be downloaded onto, where the rest of the data on your ad card is shared and is used for music, videos and lots of other custom stuff you can add. As for the cache I leave it at the default, this is where temporary data for apps is stored ( for example when you play a youtube video, it is temporarily stored on this partition.

Ah, that's good to know. It makes me wonder, though – can I resize partitions in some way? Say, I created a smallish partition setup for ROM slot 1, then another one for ROM slot 2, and then have a bit spare; can I allocate the whole space to ROM slot 1 if I no longer need ROM slot 2? Or to do a backup, clear the partition setup, then restore the backup into newly sized partitions?

safestrap not working on my kindle hdx 7"
Hi my kindle is already rooted and I used towelroot. I have supersu installed too. I'm currently on the step of where I should install safestrap, but it seems safestrap is not working on my tablet. I tried 3.65, 3.72, 3.75 version of safestrap but it does not work. It always restart normally. Not in recovery. Pls help. 13.3.2.8 version. Thank u in advance.

Have you blocked OTA with HDX Toolkit? If not your device will likely brick if Amazon attempts to push an update. At present the blocker in HDX toolkit is the only one that works on 3.2.8.
Your attention should be focused on this task; can deal with safestrap once OTA block is in place.
ya I had to learn about that the hard way
I'm curious if this is possible with the stock rom any of my current attempts seems to fail with apps not being able to load properly.
I'm assuming there are some dependencies and it's not possible to remove all the gapps from the stock rom only to replace them with the apps from opengapps.
main reason is I don't want things like google movies / chrome / the google app and most things that you can get from the app store I rather just install the app store version but I'm thinking that might not be possible or it would be a bad idea to try this on a stock rom. Even if it is rooted.
Why you don’t Just disable this app.
If you are rooted there is a debloater app for stock OOS. You flash it in TWRP, an Aroma installer comes up and you can pick which Google and OP system apps and some non essential services that you would like to uninstall. It works very well.
https://forum.xda-developers.com/oneplus-5/themes/aroma-oos-debloater-1-0-t3630135/page7
Aroma debloater seems to have been removed but thanks for the link. I'll check around in that forum.

I already have a lot of the gapps disabled but on my previous phone I was on a custom rom and I prefered just not having the app entirely.
Hello new here and while I have done some searches I am not quite finding what I am looking for which is maybe because I am not asking the right questions or searching for the right terms so hopefully someone can direct me to the right place!
I have an old Galaxy Grand Prime Sm-G530W running Android 5.1.1. It has 8gb storage and I would like to maybe remove some of the apps that I wont use, are not useful or are just bloatware.
However I am not sure what apps are what and which one I should avoid removing?
The phone will be used primary to make calls, will not be on a data and only use free wifi hotspot and the wife from my home.
I would like to maybe keep some kind of google maps ability, I do not want chrome but rather would use firefox along with ad blockers etc I know work well for me on FF.
I have have done some research but not a phone expert by far so I am not sure I want to root my phone, install custom roms. I read something about remove bloatware via "remove the pre installed apps using ADB commands" however figured I get some tips advice from people that know what they are talking about.
Ideally it would be great if there was some kind of program I can just plug into from my PC or some such that allows me to then simply remove the samsung and google bloat or unwanted programs so I could gain more room for apps I do want.
Right now after factory reset it uses like 3.50GB out of 8gb.
is there any Debloat program I can use on it out there?

Hello member of this small community, well the best way to remove bloatware is by root, the process is relatively simple.
1) Download the twrp recovery (.tar) belonging to the model you have.
2) Install it through Odin
3) Install Magisk Manager
With this done you can use applications such as root uninstaller, another alternative is to look if there is a custom rom for your model, but do not expect much as many roms have been abandoned and only a new project is kept alive, if the current rom does not present problems in performance, I recommend you leave it alone and start removing junk apps, another recommendation is to install SD maid, a great app for cleaning junk content of the phone.
