[Q] Change Default USB mode - Android Q&A, Help & Troubleshooting

I'm posting here as the forum specific to my device doesn't seem to have enough exposure and I don't think the solution I'm seeking is device specific as such. I had posted this without any replies.
I would like to know where the configuration for the default USB connection mode is stored. Ever since I started using an SD card, connecting the phone to a PC would always start mass storage mode, making many apps unusable.
Running a Custom ROM variation of the stock Huawei P7 -L10 on android 4.4.2 (EMUI 2.3).
Phone is rooted.
Many thanks!

Go to Settings > Applications > Manage Applications
Find that application and uninstall it
Or if you want to wipe the phone clean (Make it like you bought it) go to Settings > Privacy and touch Factory Data Reset
Thanks for replay, but I can't open settings or anything else becouse it is freezing. It's not phone but media player (device for watching movies surfing the web etc.)
It has android 2.2

[Q] Can not connect phone to PC when ActiveSync is configured- any work around?

Hi,
When I configure active sync account on my phone, the active sync requests to be (one of) the device administrator(s), I understand this and it happens in all the phones I had, but with SGSIII it asks permission for much more things, the one that I don't like as its not practical is that the phone (both internal memory and external) will not be seen by the PC when connected. Is there a modified Email.apk with these security settings removed? I searched the forum and didn't find anything useful, I'm running (odexed) stock ROM 4.1.2 rooted.
any advice is welcome

[Q] Android Data Recovery

Hello
I have accidently overwritten some photos on my Google Nexus 7 and would love to get them back. I`ve tried various recovery programs on Windows but none of them can read my tablet in MTP mode and I can`t connect it in mass storage mode. I have read that one way is to make a VHD image via RAW of the hard drive onto the pc, where the recovery programs can access it. The trouble is I I think have to root the tablet which i don`t really want to do
1) Is there a way of creating this file without rooting?
2) Does anyone know of a recovery program that uses MTP?
3) If I really HAVE to root, whats the least destructive way of doing this?
Any help would be greatly appreciated!!
Android operating system has changed the entire concept of smart phones and given it a new dimension. Now people know, how different is to use an Android smart phones than any other smart phones. With so many exciting new apps being developed every now and then, it is really very hard to lash yourself to use only one or two. Now, your Android phone is turned more like a storage device with lots of snapped pictures, audio & video files, latest exciting apps, mails, messages and so on. In situations like this, losing or accidentally deleting file is a common issue that most of the Android users face.
I used an app called Undelete once at it worked well.

[Q] bootloader unlock password- Huawei G630-U00

hello,
I couldn't find any other forum to discuss about this version of Huawei mobile phone. I really need help since the last legitimate EMU update ruined the whole system and now my new mobile phone that I have never had a chance to use it is like a trash device... I hope someone here can help me to recover it since i tried all ways I found on internet.
I bought this mobile from China and bring it to Europe. Since I wanted to remove some chinese default software (that wasn't basic software but really annoying), I used an app and rooted the mobile phone. so I removed some of chinese stuff and installed some of good software. Everything worked fine and I tested skype and I had high resolution picture with 8 Mega pixel camera. I tested all its functionality and it was really good...
I noticed that there is a new legitimate update for this OS, since I still didn't have any sd memory, I couldn't have a backup of this old system and this was a big mistake...
anyway... I let it do the legitimate update for EMU... but immediately after reboot, I noticed that Camera and bluetooth are out of functions... so I first thought the problem is with bluetooth configuration but I was wrong since the internal memory was read only and no longer available.
I formatted the internal memory via computer (the part which was available) but no luck... I bought a sd card and changed the storage from internal to external but this didn't help to function bluetooth and camera...
I had a back up from /system/apps and then removed manually the bluetooth.apk and also its odex file. then restarted the system, clear dev cache and tried to install bluetooth.apk again. but I received error message and couldnt' do that. so again I copied those file back to its location.
So bluetooth turns on now, can send signal but for receiving or sending file, it fails, It can also pairs with other device.. So I thought it should be something related to permissions. I again checked the bluetooth permissioin on /etc/permissions/platform.xml and notice they are ok.
I changed the permission of storage and added the external storage to the list and added group storage_rw.
but this also didn't solve the problem with camera and bluetooth.
several times reset to factory mode didn't solve the problem...
I tried to hack the bootloader but I could not unlock it... I sent all information to [email protected] and asked them to send me bootloader password and provide them with all detail information about the device and accepted that the device is out of warrant but I received no response...
I installed "safe system remover apps" and after having backup of Gallery2.apk, I uninstalled it (it is related to camera and all gallery information)... but with no luck I could install it again...
So, I am really hopeless now since I don't know whatelse I can to do... the system doesn't functioning and I need to load on it the custom ROM but the device only can go to fastboot and cannot load the recovery mode anymore and factory reset from the UI is only reset the mobile to fastboot without doing anything else.
I tried to run the factorymode.sh from the device but I receive error messages to access some files such as bluetooth parameters/power
I couldn't myself find this file on the directory that it looks for.
I would really appreciate it if you can tell me any way that I can unlock the bootloader from the device (because outside of the device I tried different applications but with no luck...)
I have a cutom ROM for G630-U20 (not exact version for this device but almost similar) and if I can have a bootloader password I can try this one or any other customized ROM.
I would appreciate any way that you can show me to solve the problem.... either by changing permissions to solve this problem.
Thank you.

HELP FROM DEV, bad virus/rat

(Im new to XDA and initially posted this in the wrong place and do not know how to delete the last one. If admin deletes one because of multi posting, please keep this one up) my phone is infected with a virus that has imbedded itself in my system settings, any anti malware apps used do not detect it. when plugging my phone into my computer (for developer access) it began to install the device driver. once the "device driver" installed it took all administrative use away from me and locked all drives. I do not have ABD access or any computer access at this point. this phone has killed 3 laptops and a desktop. the only way ive been able to partially stop the virus is using a firewall to block it. since my phone is NOT rooted I cannot delete system files containing the virus. I noticed the virus will edit apps and system functions to try and hide itself (Google play services) for example. someone is using a form of remote access to control things and change settings. it is possible that someone (close family or friend) may have gotten their hands on it to install the virus. factory reset does nothing as the virus is stored in system settings. phone cannot be hooked to Pc without severe repercussions. I cannot gain root access through any rooting apps for some reason. only tried to access system settings. I HAVE TRIED EVERYTHING.

First of all, you should disable autostart on your laptop/PC ( on Windows 10 press [WINDOWS] + "Setup"). There you can config autostart/actions for sd-card, mobile memory and your phone (scroll down on this page). No auto play or sync (fotos/media) for ALL devices is recommend. Don't log in your PC as admin, use a non-admin-account for testing with your phone.
Take a fresh sd card, copy the virustotal scanner on it (take it from the attachment at that post: https://forum.xda-developers.com/showpost.php?p=77053739&postcount=11), switch the sd-card to "read only" (https://www.youtube.com/watch?v=SgguVeKWCTw), put it in your phone, install the virustotal app from the sd-card, go online and let it run. So we figure (hopefull) out, which malware it is and where it is located. Write down the findings (name, location, how much scanner find it) and post it here...
Are you shure, that your ADB-SW/Drivers for the PC/Laptop are okay and clean? Plz post additional Infos about your phone...
I think, someone may have taken my phone, rooted it, and installed or is possibly using Samsung KNOX? If this were the case is there a way to break Knox without a PC? I don't want access to anything in it, just to destroy it. If this is part of the problem, just a quick theory and question I will get back to you with more information. Thank you

There are malware in the wild, which can root you phone (like "Dvmap"). In this case you only have one chance about the complete flashing of the device with a clean rom. This type of malware also infects system files, so it cannot be quarantined and removed. At the moment I don't understand why the computers you used for flashing don't work anymore. if the drivers / software are OK (do you have the right versions for windows7/8/10 and e.g. 32/64 Bit) this should not happen? Does this work with other smartphones? Normally the phone is switched off for flashing, so Android is not running. Also autostart should not work then.... that would be completely new behavior.....
