Developer Mode not starting (N9)
 

So, this has been talked about twice in the forums but with no conclusion.
here:
http://talk.maemo.org/showthread.php...developer+mode
and here:
http://talk.maemo.org/showthread.php...developer+mode


I share this problem, so I thought a detailed walk-through of the error might be useful for solving it.

First time I powered on my N9, I was on PR 1.0, and enabled Developer mode successfully, but after the next restart, the Developer mode was disabled and trying to enable it again would result in the error:


I thought updating might solve the problem.

I flashed fiasco up to PR 1.1, didn't help.

I tried installing manually, using the files from http://harmattan-dev.nokia.com/pool/...eveloper-mode/ , but installing them results in an error saying that the dependencies could not be resolved.

I reflashed, both fiasco and mmc. Again no use.

Does anybody have any idea what to do?

:?

Re: Developer Mode not starting (N9)
 

i had this same issue but a simple reflash solved the issue

good luck

Re: Developer Mode not starting (N9)
 

You can use "dpkg -l <package name>" or "dpkg -l | grep <package name>" (the "-l" is a small L) to see if it is installed. Installed indicates with a "ii" and uninstalled with "un" infront of package. No need for devel-su. If the output is empty then it doesn't exist in the repo and need to be installed through the browser.

To see dependancies you can use "apt-cache showpkg <package name>"

Re: Developer Mode not starting (N9)
 

same issue here as he has linked to my thread.

i have been able to force the installation and get it to allow dev mode....BUT

i cannot root the device.

after entering devel-su/rootme this is my output:

Re: Developer Mode not starting (N9)
 

That sounds like an aegis error.. Do you have all the necessary packages installed?

Re: Developer Mode not starting (N9)
 

thanks to rainisto for helping, i was not able to get devel-su working, but opensh still gives me root!

here is the link he gave me to dl the opensh.deb file.

after you install it, open terminal and type

and it will give you root access.

Re: Developer Mode not starting (N9)
 

guys,

i reflashed my n9 and now i can not get developer mode to install,

help please!

Re: Developer Mode not starting (N9)
 

I had this problem after flashing phone including emmc.So I flashed it again and same problem.So I now cleared the device and flashed fully again.this time I decided to use gprs connection instead of my broadband and this time it worked!

So I'm not sure if it was clearing the device and flashing or using a different internet connection!

I love this phone by the way

just seen this

Re: Developer Mode not starting (N9)
 

Up it goes.
Flashed 1.2 with NSU and all is well except this. I was running the store I think and that might have screwed with installing this (even though nothing was installing IIRC.)
Each time I try now though, it just starts installing but says it is interrupted each time.
Does anyone know all the packages included with it? I know they're in /var/cache/apt and I think if I just delete them and try again, it should work.

If not, anybody have a better idea? Reboots also didn't work.

Re: Developer Mode not starting (N9)
 

"FTR: After a factory reset of a N9 I got "Installatoin interrupted" errors when reactivating developer tools. Package "sdk-connectivity-tool" was broken. Fixed it by going to http://harmattan-dev.nokia.com/pool/...an-beta2/free/ and installing from there packages develsh, openssh and meego-terminal. After a reboot I could use the meego terminal to "ssh root@localhost" and "apt-get reinstall sdk-connectiy-tool", after that enabling developer thru the GUI"

All credit goes to clbr on an IRC. http://mg.pov.lt/harmattan-irclog/%2...10-26.log.html

I ended up hard resetting thinking it since I couldn't seem to resolve some repo settings or something I guess.
Either way, I think I might have been successful if I had downloaded on the mobile network (like I did after the hard reset) and manually installing the apps like he said. I tried but it always said it couldn't get the dependencies.

Re: Developer Mode not starting (N9)
 

hallo , I solved same problem now with a total flash (legay+mmc) but I'm sure that mmc flash is not strickly necessary

Re: Developer Mode not starting (N9)
 

I know it's an old thread but in case someone ends up here from Google as I did, this is what worked for me as well after installing PR 1.3 on my N950.

I couldn't enable developer mode - it always failed with the "installation package not found" error. Reflashed 3 times using different parameters to try and see if it would make a difference, to no avail.

Ended up setting up a 3G access point and connecting via 3G instead of wifi, and, lo and behold, it just worked! This is really weird as the wifi connection worked just fine for everything else on the device (and on every other device I have). And it's a 76Mb/s fibre optic connection from BT - nothing dodgy there.

Re: Developer Mode not starting (N9)
 

It's happened to me too many times..
I found 2 solutions for myself:
1. Like you, using 3g instead home network
2. Edit my home network by adding parameters in "Advanced setting", only iIP and DNS sections. And it started to work with wifi too.

It's weird, but after the last reflash it worked for me on wifi without this setting.. Can't explain why...

Re: Developer Mode not starting (N9)
 

Usually the reason is that devel-mode can only be enabled when you have set date to corrent one. Usually after reflash you have old date from factory image and most of the people forget to set the date/time before enabling devel mode. And if you enable 3G you usually get date/time automaticly updated from the operator and devel-mode install starts to work ;)

Longer explanation: devel-mode package signature is 6 months newer than default date on factory image, and if you try to install it without setting the right date after reflash, you run into dpkg/aegis signature error, and UI just says not found :)

Re: Developer Mode not starting (N9)
 

I'm a newbie with this kind of tuning. I would like to test a new keyboard (an unfinished .deb file), but its installation fails (unlike the keyboards from Nokia Store). And the manual installation with terminal fails, because I cannot do it as a root: my N9 does not find su, sudo nor devel-su. Therefore, my quetion is: Are there any straightforward instructions of how to add all the additional files to N9 for operations as a superuser?
This looked promising:
... but the link does not work any more.

Re: Developer Mode not starting (N9)
 

Hi,
would you more explain about what you've done in your home network? ADSL modem you mean? firewall rules you added? I'm somehow confused about what you wrote but have the same exact problem
Thanks a bunch

Re: Developer Mode not starting (N9)
 

Please I need your help...:(

Re: Developer Mode not starting (N9)
 

What about reading ???

Re: Developer Mode not starting (N9)
 

Had to flash N9 after bootloop. Installing applications is pain... as I am not too familiar with all those repos and dependencies. But how could I now enable developer mode?

"Installation failed, package not found" (or something similar)

Re: Developer Mode not starting (N9)
 

You have installed Ancelad's repomirror? https://openrepos.net/content/ancelad/n9-repomirror

Re: Developer Mode not starting (N9)
 

Oh dear(s),

how often are we supposed to point to that link?
Enable third-party app installation, download the package and tap it in the transfer window.

Thank you for helping.
