This is my first post, so apologies if this is in the wrong place or has been asked before (I have searched and found some answers, but none of these worked)
Basically, last night whenever I tried to use an application on my HTC HD2 I was getting the following error message:
"The file xxx cannot be opened. Either it is not signed with a trusted certificate, or one if its components cannot be found. If the problem persists, try reinstalling or restoring this file."
In searching for the solution, a lot of people are saying that I need to edit the reistry. (Specifiaclly HKEY_LOCAL_MACHINE\Security\Policies\Policies DWord = 0000101a - Change value from 0 to 1)
I have tried downloading the recommended registry editors on the forums (Resco Explorer etc.) but am unable to install because the "program is from an unknown publisher." I click yes to get pass this initial message, like I always have done in the past, and the following is displayed:
Installation was unseccessful. The program or setting cannot be installed beacause it is not digitally signed with a trusted certificate."
I have also tried using a program recommended called CeRegistryEditor and using my PC via ActiveSync to edit the registry, but am getting an error message "Access Denied!".
Does anybody know any other way of editing the registry? Am I actually doing the right thing? Are there any security settings that I need to disable to allow CeReistryEditor to edit the registry?
This is really bugging me, I have only been without my apps for about 12 hours throughout the night but it is hard to live without them!! I REALLY don't want to perform a hard reset and will do anything to avoid this!
When I get this I just remove evertyhing to do with it on the phone and re download it (the cab file usually) and it seems to work.
thanks for your reply. I have tried this but when I try and reinstall I am getting the message: Installation was unseccessful. The program or setting cannot be installed beacause it is not digitally signed with a trusted certificate.
I think that the security settings have been changed, but I cant see how to change them with editing the registry which I am struggling to do
Can I ask what app you are trying to install? Or is it any app?
Multiple Apps that were running OK yesterday, but not today. I think it is all the apps that I have downloaded from Omarket.... Omarket isnt working either!
Hi,
Any luck on this. I m also facing similar issue after installing Android on my HD2.
I have the exact same issue after running Android from SD card. No application (non-stock ones) are working anymore. Like 3rd party certificates are being blocked or something...
For everyone with this problem, download Mobile Registry Editor and connect your phone to your PC via USB, then start the Editor and go to "HKEY_LOCAL_MACHINE\Security\Policies\Policies" and search for the DWord "0000101a" and change the decimal to "1", that will fix your problem. This problem happens to me if I "reboot" while in Android instead of turning the phone completely off and then back on.
Edit: Added link to download.
As a side note, I always did this to mine while running Windows Mobile, then booted Android after fixing the registry.
and when this is not possible

Hi,
I also have the same issue after loading android from the sd-card. I have also re-installed the stock rom and the problem still persists. Im also unable to install any reg editors as keep getting the "not signed with a trusted certificate".
I read that a cooked rom may be a solution around this but I liked the set up I had and wanted to keep my original rom so any other suggestions would be appreciated.
Thanks
Lee
Exactly the same problem.
Non-stock programs not working after failed boot of android from SD card, and I'm unable to change any registry entries either. Practically I'm locked out of my phone, just the basic functions working. Any help would be greatly appreciated!
if forget where I originally found this link (its on xda some place)
http://www.internet-tools.co.uk/blog/wp-content/uploads/2008/11/sda_unlock.zip
but run this first and you no longer get the access denied when using the mobile registry editor , hope it helps.
I have the same problem, just remove the program that was not working, pull out your memory card , then delete the files in the sd card except the application installer, hard reset your phone, and remember to go to SETTINGS-UPDATES&FEEDBACK-ERROR REPORTING-DISABLE ERROR REPORTING, and turn off your phone, put in the memory card and turn your phone on and install the application one by one, the application installed will work as normal, Good Luck, remember to back up your data before hard reset

Hi All,
New to the forums and have been doing a bit of modifications to my Settings.apk and settings.db files thanks to all the very helpful people in the forum but I'm stuck in changing the default setting for the screen lock.
Essentially I want to stop the Swipe to unlock screen from appearing after a device restart. I have stopped the display from sleeping by modifying the "screen_off_timeout" value in the settings.db file, but that doesn't stop the lock screen from appearing after a restart.
Does anyone know where this setting would be stored? I tried changing "lockscreen.disabled" in the "secure" table to "1" but it seemed to default back to "0" after a reboot. Is this what I should be changing but am doing something wrong?
I am using a generic chinese Allwinner A31s tablet with Android 4.2.2.
Thanks in advance for any help offered.
Hi ,
I was trying to install certain application, but I couldn't because of my android version, so then I rooted my device and I edited configuration file (system/build.prop) with system variables such as API version, android version, name of device etc. First I changed only my android version from 4.3 to 5.1 and I rebooted my tablet and my system was fine, but my application still doesn't open. Then I thought that API version could cause the program to start, so I changed it from 18 to 24, I rebooted tablet and every Google Service was crashing with message "Unfortunately, Google XXX services has stopped"
I was trying to open configuration file again, but it's impossible, because of error messages.
I did force restore android system, but it doesn't restore system configuration files
And I installed app with gives access for editing system files again (i got apk file by usb), but I can't open it.
My tablet: Huawei Mediapad t1 8.0
Thank you for help
Hello Everyone. (Assalamualaikum)
This is my first thread on XDA.
Here is the problem - i just flash https://forum.xda-developers.com/galaxy-star/development/port-resurrection-remix-t3429810 this rom yesterday. And now, i can't save my BUILD.PROP (in stock rom, file saved without any problems). ALSO i can't install most of my favorite apps as - Gboard, kiwi, xposed etc.
This is what shown, when i try to save modified build.prop --> java.io.IOException: error after write by shell
So, is this problem to the rom only or there is any other way to solve this two problems???
1. build.prop showing - java.io.IOException: error after write by shell
2. can not install some apps which i could in stock rom
Walikum-usalam
This can happen if your phone does not enough permissions to change it and of the apps they are not installing because the apps are not supported by the ROM
If you want to change the build.prop and install apps you can install Teamviewer in your computer and tell me the partner ID and password
I will connect to your computer and fix it
Assalamualaikum everyone and resurrecting this thread again lol. But im kinda having a issue which is kinda similar, where if i change my build prop to pixel 5 my gboard creates a gap in the bottom area which mimics the 16:9 ratio display but my phone doesn't have a 16:9 display. So any possible fix to this as i want to get rid of this odd blank space while typing? thank you
