[Q] Where is the OS version number stored?

Hello, I have a Samsung Taylor (developer device) stuck in version 7003, and I'm trying to force-update it.
So far, I have patched ChevronWP7.Updater to apply the update if it detects that the phone version is 7.0.7003.0 (by default it only works if version is 7.0.7004.0). Everything works well, the program says the device was updated successfully, but when it reboots, it's still stuck in 7003.
So, I was hoping if anyone knows the registry key/system file where the current OS version is stored, to try and change the value there.
Sorry, there is literally NO WAY to update the Taylor or the Panther. Changing the OS version, unbranding or even changing the model number (i've changed mine from GW910 to LG-C900) through the registry won't force the update.
But to answer your question the key is "ROMVersion" (string) which is located in
Code:
HKEY_LOCAL_MACHINE\System\Platform\DeviceTargetingInfo

Does anyone know if it's possible to change the version number in the registry to force an update? I'm stuck on 7003 on a Samsung Focus and want to try anything that will remotely give me a chance to upgrade this phone.
I've googled all over the place but haven't found a dump of hklm\system\platform\devicetargetinginfo or any other relevant areas of the registry. Hard with the SamsungRegistry app too, as you can only find/write to keys that you know the path to.

I found the WP7 Root Tools app, and I'm using that now to poke around the registry.
I gave up on this last night after poking around in the registry for 2-3 hours. There was nothing that specifically identified my OS version as 7003.
your in the wrong section , go to the developers section and look around there , no need to google, all the info you need is in there!good luck!

[Q] Keeping browser alive in memory on stock firmware

I am on 4.04 stock, rooted. I am using Opera Mobile and want to make it stick in memory by decreasing the oom value. Can you give me advice how to do it? So far I tried editing build.prop adding 'sys.keep_app_1=com.opera.browser', which didn't work (the line was added, I restarted and nothing). I tried running a an old holdapp.sh script via terminal, got an error that 'nohup' doesnt work. Auto memory manager can change the value but it doesnt stick.
Please help. Thanks

you could try installing es file explorer, open the app, go to its settings, then to root settings and check all 4 boxes. next go into the root directory and find the system folder. there you should find the build.prop file. open it using the es file editor. look for the lcd density line and you can change the value. try lowering the number by a quarter. see if that helps.
hope that this wasn't too confusing.

You could use root explorer...
Procedure is same only you have to open build.prop in edit text mode and resize the value...
If you are using a 4.3 inch smart phone then it would be 240, change by 10 or whatever you like...
Just don't change it to very low value or there will be problem...
Reboot the device and see the change...

[Q] HTC One S and wifi channels 12-14

Hi.
I have found that my rooted HTC One S 4.1.1 doesn't recognize Wi-Fi channels 12 and 13 (14th channel too, but it's not a problem for me).
I've red about fixing the Regulatory domain on other threads, even found the solution to change it with the help of SQLite Editor: I've edited the /data/data/com.android.providers.settings/databases/settings.db, table "secure", field "wifi_country_code" and changed value from "ru" to "eu", but it haven't changed anything. Also, after reboot it returned to old value "ru".
I've also tried to do this with sqlite3 - with the same ending and no result.
Does anyone have the fix for this problem?
P.S. I also tried WIFICodes from here: http://forum.xda-developers.com/showthread.php?t=1982149

Hello,
I am curious what rom you are running, If you are running stock JB 4.1.1 then the system partition has write protection. Any thing that you do the it will be undon upon a reboot. there are modded kernels in the cevelopment section that have gotten around this write protection. You might want to check out this thread, but only if you have a S4 model http://forum.xda-developers.com/showthread.php?t=2083229. Hope that helps.

I have a stock 4.1.1 rom, but I installed a kernel patch so I can save changes on /system partition. It was checked during su, busibox and sqlite3 instalations. Patch was also found on this subforum.
I'll check now if /data partition is write-protected.
Added later:
Ofcourse /data is not write-protected. I checked it by creating a new folder and new file in it. Also, in sqlite database mentioned before there is parameter called "wifi_on" and it saves the value during reboot.
So, it's not a problem of a privileges and write protection.

Emergency call only.

Hi all, I have the title problem, mi nexus 5 won't take signal with my Wind (ita) sim. I have tried two device, galaxy ace plus and galaxy S5 and they can take signal using same APN and located on the same desk in my house.
I've searched a lot on XDA and other forums to get a solution, but I can't find anything that's can help me. I can't seen it to Google because I can't find his original box and the original receipt.
My phone can take signal only using "xTraSmooth" rom, but is very old and I want to use Pure Nexus.
I've added this string to my build.prop it was posted as a potential solution:
"#settings
telephony.lteOnGsmDevice=1"
And I've changed *#*#4637#*#* option to LTE/GSM/wcdma auto (prl)
But at every reboot it set itself on LTE/GSM, with or without the build.prop string.
I know that is a common problem, but no one found a real solution.
Thanks in advance.
If everything works on a stock rom, you need to use a different custom ROM.

Today I will try to flash xtrasmooth or a stock factory image, thanks for the tip
----\\\UPDATE///----
Flashed same xtrasmooth, inserted string in build.prop and i do the trick with *#*#4636#*#* and the phone set itself to LTE/GSM auto (prl).
I wanto to use my nexus, why this phone have a lot of problems?
----\\\UPDATE 2///----
Flashed miui 8 global by Dio_S used the build.prop string and now work, i have to be lucky with a rom now? i don't like miui, and i will test other rom, i hope in a normal rom...
----\\\UPDATE 3///----
(i hope last update)
I've searched a lot to reach the best solution with this phone.
Now im using DarkRom and i've found a solution! Or something like a solution, hahaha.
I've downloaded "Nexus5 field test"
Give root permissions (magisk or super su, think doesn't matter)
Select three dot
Hit "Root Settings"
Select three dot
Hit "Settings (view)"
Hit LTE
Hit edit
Write your service code (id you dont have this code use this guide to get it using adb https://forum.xda-developers.com/go...radio-enable-lte-band-3-nexus-5-d820-t2928561 )
Use these settings:
Lte Enable/Disable (enable)
Band26 (disable)
Band41 (enable)
Band25 Proirity (1)
Band26 Proirity (1)
Band41 Proirity (0)
hit back to reboot and now should work, if not i don't know.
You have to reboot every time you select Airplane Mode and it will work!
Good Luck!
Can i up this post? If someone would to test my solution i will be very happy!
