I want to make some kind of secure android device for myself.
First: I want to remove gsm, bluetooth, gps, nfc device drivers and just leave with wi-fi.
Second: Want to remove all the apps that produce internet traffic and send data to internet except app that i use.
What i have done: I have rooted my ZTE Blade X3 (T620) and with root explorer started to remove files from /dev/ directory, but in fact i do not know what files i have to delete get my phone work after reboot. I use Titanium Backup to remove the apps, but deleting some apps make phone not starting, so i need to go back to TWRP and recover from backup to do everything from the begining.
Can anyone point me from where i have to start learning things to do all the stuff?
What have i need to do? Build kernel or build my own ROM, just remove apps or what?

Sorry for having to ask this, but Im a real novice when it comes to android (after being a windows mobile junkie for so long)...
What is the best way to backup all my settings/apps before rooting/unlocking, (things such as installed apps, email/facebook/twitter/etc account info, home screen customizations/widgets) and then restore them after the upgrade?
I am use to using UC on the windows side of things and it was quite involved. I am about to do the whole rooting thing (for the first time with an android device) and I am just trying to have all my bases covered.
Thanks in advance
[App] Es File manager
If you want to back up your apps before you root or upgrade I suggest you save the folders on your SD card. You can also backup your stuff on a cloud data base. Also ES file manager allows you to back up your apps. If you want to back up everything then use titanium backup but it requires root. Im unsure of your situation so I stated all the methods.

Huawei Prism U 8651T running Android 2.3.6
1. Yes I have read similar threads -they are about adding stuff or running new ROMS - I want to remove stuff and run stock ROM
2. Somewhat familiar with Linux . not so much android even tho linux based. Took the test and yes I think it's do able.
3. Yes found rootuing howto on my device on these forums
some questions before I root. all files on my Linux box are readable whether roor or not. Just can't modify unless root. I was reading files on android and they are locked down with encrypted looking stuff like when reading Windows files.
1. Will I be able to remove/disable factory installed google and t-mobile stuff or do they have it lockd down to where even if I'm root I can't do it.
2. howto says phone must be unlocked first - other s say no
3.Some howtos claim rooting should be done with non-active sim card - true?
** I understand that many services rely on google and tmobile apps but they are killing my battery and I can't force stop them ( they just relaunch in a few minutes - and I don't want or need all that cloud syncing junk***
Thanks for any help
Well, you do know what you want, so rooting is probably your thing, and yes you can delete T-Mobile apps and services and other things you might want to remove, including Google apps. Just be careful and don't delete google services like GmsCore.apk, Contacts etc. Maps, Google+ and all that stuff are safe to remove.
Most apps are located in /system/apps, but there are also some apps in /data/apps. Be careful when you delete system apps, so you might want to install Recovery while you're at it so you can make a NAND backup (backup of your ROM) in case something goes wrong, or you want to return to stock once you're on a custom ROM.
I can't give you an answer on the rest of the questions, since some of them might be device specific things, so i don't want to tell you something wrong.

Well not sure EXACTLY what I want but basically I want a phone that acts lke a phone and not all the social media cruft and "ALWAYS ON" junk running in the background. And if I do need it I will turn it on and off myself.
Thanks for the tips. I will begin posting oin the appropriate forum.
Please forgive my ignorance.
There are 2 questions here
===================
1. can I damage the ROM files if I have root access on an android device?
Or ... in other words, if I delete apps that I don't want in the system/apps folder then am I also deleting them from the rom?
I would like to know ......... if I make a mistake and delete an app from that folder that stops the phone working, or even booting, will a hard reset restore the phone, or will it not be able to because the rom will now be missing essential files?
2. Can I backup this version of the OS that I have made, the actual one running, including the deletions and customization or does a backup of the rom only backup the unchanged rom that came with the phone (and, in the process, throw away the changes I have made)
I have searched for answers to these basic questions but to no avail. Perhaps the answers are too self-evident to developers or the search terms are not definitive enough.
I will make great strides once I clear up this confusion.
Thank you.
You can use TWRP to make a nandroid backup which will backup your system AS IT IS. The whole thing, rom, kernel, apps... everything.

1. If you don't know what you're deleting, yes. It's like clearing files up on "windows" folder on a windows pc.
2.You can use either a custom recovery (e.g. c.w.m., t.w.r.p.) to backup the entire phone as it is, or use an app like the titanium backup, which does practically the same thing.
3. Don't ask for forgiveness. That's what xda is for. Learn more about phones and tablets so you can get the most out of your ones.
A system file is the rom. Reset will not fix. Use Titanium Backup.
Hello, let me explain my situation
I am using Lenovo a850
I've rooted my phone, granted supersu access to root explorer, be file explorer, and a few of other apps and still, can't delete bloatware. I need to do this, because my phone came with 30 useless Chinese apps, they are taking about 350mb of my internal storage. Same thing happened when I tried to change Boot logo.
When apps that require root asked me for access, I granted it, but when I tried modifying files, an error occurred.
I need to delete these apps, because they are taking a lot of my internal storage.

Just to be clear, I tried many other apps like Root browser etc. but same thing happens
I guess that I've made some kind of mistake that I'm not aware of.
Thanks for futher assistance!
Hi
Thanks for writing to us at XDA Assist. Have you tried using an app like Titanium Backup to remove the unwanted apps?
Thank you for your reply
I've tried that, but same thing, app is "deleted" until I exit titanium backup, when I come back in it, apps are back there. I've tried removing them with recovery exploit, but after reboot, nothing changes, app is still there.

Ok. It might be a good idea to ask the A850 community to see if anyone who is experienced with the device can help you. You can find the A850 device forum here:
Lenovo A850
And within it there's a q&a section here:
A850 Q&A, Help & Troubleshooting
Go ahead and ask your question there.
Good luck!

Hi, so it has been a long time since I have worked with custom ROMs or root access on an android device (back when the Nexus 2 released) so I don't really remember anything and know nothing about how the android environment has changed.
The reason for my problem is that I was "hiding" sentimental/sensitive material in a folder associated with the Google Drive application using a file manager app (cut and paste into Drive folder) so that it wouldn't appear in Gallery scans, and when my drive app wasn't working as expected I (stupidly) uninstalled the update (can't actually uninstall the app on stock ROM) causing the folder to be wiped. Now I'm trying to find a way to recover the files but all the solutions recommended by a google search that I've tried require root and from what I know, correct me if I'm wrong, unlocking my bootloader to gain root access will wipe my internal storage which would probably defeat the whole purpose(?) of trying to recover information as it will overwrite the sectors. So does anyone know of anyway that I can recover this data from my device? I am willing to root as long as it will yield results.
tl;dr - need to recover files on stock P20 Pro (locked bootloader, no root), please help I am lost and noob now
Thanks in advance!
