My father brought home a cell phone he found in the woods, and I thought I'd charge it and turn it on to see if I can find out anything about the owner. (Needless to say I got no further than the lock screen.)

The phone is now turned off and plugged in via USB (not connected to the computer, but directly to the electrical outlet). However, the screen now reads "Firmware Update - do not unplug the USB connection until the process is complete", with a progress bar stuck at zero. It also refuses to be turned on again.

What's the best course of action? That is, can I safely unplug the device? I would assume so since it's only connected to the electrical outlet, but who knows what's going on behind the scenes, and unplugging it may leave it in an inconsistent state. I'd also like to avoid connecting it directly to my computer.

I'm probably being overly cautious, but I have no experience with LG devices and it's someone else's to boot, so I'd like to make sure I'm not making any of the stupid mistakes I'm prone to making. Better safe than sorry.

Once when I plugged the LG phone to give it a full charge, it did this firmware update stuck on 0% thing. I fixed it by just holding the power button on the right and the volume up button on the left for a few seconds. It reboots just fine.

Take out the battery while it is plugged into a laptop, computer, or maybe the wall, then leave it out for a few seconds. A battery with a red exclamation point should show up and that is when you insert the battery and turn it back on.

"Firmware Update - do not unplug the USB connection until the process is complete", stuck on 0% while plugged into charger all night long without any progress, no response from any button or button combination; not even 2 minutes of holding down the power button. I have no idea how it got to that state. I think it happened at low battery level.

What worked for me :Remove plastic snap on back cover. Remove the tiny screws and remove the plastic part to get to the battery. The battery didnt appeared to be removable, but at the top left a flat short cable pops out of the battery and its terminal can be unplugged. Just slide your fingernail under and the tiny plug detaches without lots of pulling force. I waited some 10seconds and plugged the battery back in. Et voila the phone screen went straight into normal startup. The battery level at that stage were 11% (so not flat at all)

Roger, this problem seems to be elusive. It does work sometimes, but not at others. This is the configuration file for a GRP2616 that does not have the string in it that is needed.

Roger,

I think you found the problem. I did not create a username/password at all. When I put a setting in there, then the URL will populate. I have not had time to check to see if the phone accepts this setting yet, but I will let you know if this works.

I want to customize the basic features such as Contacts, SMS in such a phone. So I either want a open source code of its firmware that is compatible with one or more of such phones, or I would like to know of a vendor who could sell a cell phone within this cost range along with the source code of the firmware?

I wish there were such a phone. As far as I can tell, no major phone manufacturer provides either the source for their firmware or the specs that you would need to write your own.I think your best bet would be to take a look at open moko: _FreeRunner_GTA02_Hardware

The freerunner is a smartphone that runs at about 400$Since the full hardware spec is available here: _FreeRunner_GTA02_HardwareI think it may be possible to omit many of the parts that drive up the price, and make a derivative design that is simpler and cheaper.eg, drop the wifi, gps, bluetooth, usb, and accelerometer.However, I am not a computer engineer, so I'm not sure how difficult that would be, or if it would even be cheaper.

I looking for any info about creating firmware for button phones and people, who did it. Try to find firmware with open source code, try to find documentation, but no result. I found only Simbian OS from Nokia on github, but dont now how to compile and launch it.

The Phone Administrator initiates the Resync via the Zoom Web Portal. This method is fully described here. Using the Resync method, the provisioning and firmware will be applied to the devices immediately. Therefore, it is suggested to target specific phones or perform this action in batch after working hours so as not to impact the phone user. The Resync action should be viewed as an administration feature for troubleshooting or configuring devices with an immediate need for the update.

The Auto Polling/Pulling mechanism is more passive in nature where the devices will check (Polling/Pulling) for updates on predefined dates/times specified by each device manufacturer. The IP Phone will check with the Zoom Phone service for any new configurations and if there is a new firmware version to apply. If there are any changes, the IP Phone will apply them at that time. This method ensures all the IP phones stay up to date with the settings including device software updates on a regular basis. For guidance purposes, subject to change by the device manufacturer, the polling is typically performed when devices are not in use (For example - weekends/after midnight). This polling/pulling method is the default method for Zoom Phone service.

Maybe yours does too. This just sets the application file to the right name. Again, causing the phone to load the file, reboot, write to flash, and reboot again. Then when it gets to this section, it jumps to GETSET. When you download new firmware, the phone reboots four times as it works through all these files.

When the phone gets to that line in red, it will check against its own internal GROUP variable and jump to BACKUPAPP30 if it matches. Now you can add the firmware version you want in that section by adding the following lines to the file:

hi

I have some doubt about how to upgrade firmware in 9600 series sip phone. I notify one error when plugged in LAN port the sip phone get booting but vlan ID does not take what is the issue of vlan does not take out. Pls reply for this queries.

Sorry to hear it. So the phone is rebooting after partial download? I had a similar problem in an office that had flaky data service. The file is large and the phones probably have very basic timeout/retry/correction capabilities. It may eventually download correctly. You might want to try a different connection or move it to a different office. If the phone keeps rebooting after a full download, it could be logic in the settings file (ha and hb mismatch). Let me know if you figure it out!

There are two files that need to get loaded. If only one is loaded, the phone will reboot cycle. For example, if I set the group to 32 in the phone and include this IF statement:

IF $GROUP SEQ 32 goto BACKUPAPP32

And at this second jump, we give it the application file (ha*). I have fat-fingered this process before, and it causes a reboot cycle where it kept loading alternating hb files. Is that what yours is doing?

Is there a way to change the group value on a SIP phone? Whether I change it in System Manager or Site Administration it will not change in the craft settings? I can change a H.323 group value, but not a SIP one.

Hello Roger, I heard a rumor the 7.0 SIP Firmware resolved this issue but found that to not be true. Not sure about the $MACADDR but I appreciate your help! I am still looking for a work around as well.

Are you using SIP phones on your own network? If you are trying to supply different config based upon IP address ranges, you can use an .htaccess rule in Apache. I had to do this at the last minute when I had a site that had different DHCP settings coming from a router rather than the Windows DHCP server. I had to override the Call Server settings for that site, so I created an .htaccess file to redirect the http request from the phones to a specific file. I can post specifics if you think it would help.

Once you have the web server working, you can change your 46xx settings file to (1) tell the phones to use http and (2) point the phones to your new http server. You can use the GROUP section in the settings file to re-point the phone to the right place. As far as I can tell, you can provide multiple setting parameters to a phone and the most recent setting takes over. For example, if your settings file has a bunch of parameters in it, and then you set some group specific parameters at the bottom, these simply overwrite the settings from above.

Hi Roger am new only on this device can please help me what i need to do if i want to downgrade the version of application of 1608 model, because i want to test the headset since in the old application the quality of voice is good but in the updated version voice was very low quality. Thanks i hope you can help me Thank!

I want to fetch 46xx settings file from new utility server on my phones without upgrading their firmware. I have tried disabling the corresponding firmware on utility server but then it fails to fetch settings file. Is there a way we can set phones to directly fetch 46xxsettings.txt without looking for upgrade (96xx or 96x1Hupgrade.txt)?

This will watch the file for changes, and only display the lines that contain GET. Or, if you know its IP address, you can grep for that too. You can watch it and see what files the phone is trying to GET. If you see it attempting to get [its-mac-address].txt, then you know which file to post.

Typically, the phones are pretty good about displaying the files they are trying to GET and the response code from the web server. You might need to record it with your phone so you can play it back slowly.
