[Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin] naufalhadyan:
I never knew Grand has a carrier-locked variant... Given its target market in developing countries, not US.

Your best bet is to complain to your carrier and claim your warranty, because it seems like they have done lousy modifications to the phone...
[Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin] zelith:
The thing is these phone was purchased from China, didn't know it too that they locked the firmware but after reading from a couple of guys here, it seems it's locked. Battery is draining like crazy , 1% every 20-30 secs. I think it could be firmware but maybe it could be hardware as well
[Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin] naufalhadyan:
This could be a faulty app/firmware---which can be detected by some system monitoring apps on Play Store---a bad kernel or some faulty hardware...

There's no solution for faulty hardware... just dump it if you can't bring it to a service center :D

Can you root and install a custom ROM on a locked firmware? (sorry I've never used a locked phone before) This could be a fix if it's a faulty app/firmware/kernel.
[Galaxy Grand Duos i9082 General] DayWalker:

What is this, Samsung's official firmware? there are dozens of thread in the general section about this.
[Galaxy Grand Duos i9082 General] DayWalker:
Yup..... This is the Official Firmware which samsung released not any custom rom... So have no worries....
[Galaxy Grand Duos i9082 General] vinodr5371@xdaroms.co.in:
Update file is not on the Web site please upload the file I want this firmware please bro
[Galaxy Grand Duos i9082 General] raghavsharmaxda:
The actual thing naufalhadyan wanted to say is that why u sharing a firmware while there's are already hell of forums giving links for proper firmwares with mirrors !!..

If it is a new firmware then that's okay..but if u sharing an old firmware of 4.2.2 than just a duplicate forum is considered as spam on xda...be aware of that !!!.. Sorry if rude..just telling u :)
[Galaxy Grand Duos i9082 General] raghavsharmaxda:
Edit: the latest firmware for galaxy grand is for Egypt,Saudi Arabia...firmware links are i supoose already shared on galazy grand forums...last firmware was of Egypt which was declared laggy by many users.....

Screenshots attached!.
[Galaxy Grand Duos i9082 General] DayWalker:
Guys sorry for the inconvenience i will check on the download link error and let you guys know please bear with me ... Thank you :)

[MENTION=5607633]raghavsharmaxda[/MENTION] please be updated the fact that this aint laggy im currently using it plus their aint a working link which hasnt blovked or removed on 4.2.2 JB update for grand other than custom roms soo please be updated before you say something... Thank you! Have a nice day :)
[Galaxy Grand Duos i9082 General] DayWalker:
The Link is working now!! :)

Wants new on this firmware?
[Galaxy Grand Duos i9082 General] DayWalker:
well you'll notice that your status drop bar have more options than 4.1.2 and when you look around you see settings are arranged into tabs as Connections, My device, Accounts and more even more much faster and does use ram more efficiently plus small amount of enhancement of performance on the device.

[G2 Q&A, Help & Troubleshooting] daniel178:
Hello all,

I have a G2 running that I haven't touched, except for rooting. It's running Android 4.2.2, kernel 3.4.0-perf-g7c2d0a2, build JDQ39B, software version VS98011A. I'm running stock (just as it came), no ROMs, nothing else, TWRP not installed.

If I do the OTA update that started popping up a couple of days ago (I would like to update), will I screw my phone up? Will I screw up my root? I am most worried about losing my tethering....

Thank you for any help :)

Makes an interesting read, although the lack of comments makes it tricky reading, as does the lack of documentation of the stack-frame. Given that you have not provided such information I would assume you do not know, this is reinforced by the fact the say 'This is what is does' and then simply list the assembly rather than a pseudo-code overview - perhaps somebody else has paralleled your research and would be in a better position to provide information on its behaviour?

Meanwhile I'll assume you are still in the exploritory phase of your research and wait for a firmer conclusion - thanks for sharing however.

[General Topics] tweakradje:
I use this KEY (not a dword value guys, please read first post) for over a year now withoiut any bad side effects. I have 55 MB memory free (hard reset) and after the usual apps and data still about 35 Megs free. So I can hardly tell if it is of any use. Perhaps you guys with a lotta less memory free can tell us more here about the effects of the key.

So please share your findings. That gives resluts. I you don't wanna test fine, If you do even better.

[General Topics] boboki:
Tweak, I think the problem is your lack of providing anything to the poeple here besides a key and a VERY generic explination.

But, to show that even a rude person giving a tweak is a tweak, I am testing it now.

Mem free: 23 before reg hack

Mem free: 24.6 after reg entry

I loaded fresh from soft reboot... opened my reg program and added the entry. Then I checked memory.

I rebooted from soft boot and opened program, followed steps down to where it was, then exited. So there was a jump in ram by 1.6 meg. Thats a successful tweak if you ask me.
[General Topics] thaihugo:
Also, I'm not losing my memory when using some programs and closing them. For example, a session with egress would make me lose 3 or 4 meg after closing the prog. It seems that I come back to the same ram value everytime now. must be testing longer to confirm.
[General Topics] tweakradje:
I am a technical guy. Communicating is not my strongest point (call it rude or whatever). I think my attitude towards innovation and tweaking is more solid and thus I am not afraid to test anything if it seems feasable or likely. I cannot speak for others. There are too many of them ;O)

Take the information as you wanna take it. Use it or not. I only wanna share and carry on with my life. A lot of things still have to be discovered or understood. Life is too short you know..

[General Topics] oltp:
Very hard to tell whether this key is improving anything. I still loose tiny bit of memory (eg. 180KB on opening & closing PIE).

I'll keep it for a while & my expectations are adapted somewhat.

Regards, M
[General Topics] boboki:
Further testing.

Perhaps this hack is a little better than I originally thought. After heavy usage, all day, I usually have about 19 meg free. Well i used it pretty heavy yesterday, and its still running pretty hard at a little over 20 meg.

While this is no huge difference, I am still showing one meg savings.

*edit* Just looked, oops I had 4 emails and 2 text messages in the queue. After closing those, I now have 21.9meg ram free, as apposed to my typical 19.3ish.
[General Topics] thaihugo:
Maybe native english speaker could explain me the real sens of Dork? I thought it was a kind of insult? Or does it mean dull?
[General Topics] madkat:
The text "Dork" is not found anywhere in the whole of the Windows Mobile 5.0 PocketPC Device Emulator ROM image.

It IS found in the PocketPC 2003 Emulator ROM image.

I guess that to "Dork" the memory in 2003 is to adjust based on storage use - as you would manually with the sliding bar in the Memory settings. This sliding bar is missing in WM 5, and memory doesn't seem to adjust itself, so it's likely that WM 5 doesn't "Dork". Did anyone check changes in the storage space with the "hack" disabled?

New Oxford dictonary of English says:

dork

noun, informal: a contemptible, socially inept person.

N. Amer. vulgar slang: the penis.

ORIGIN: 1960s (originally US): perhaps a variant of DIRK, influenced by ****.
[General Topics] boboki:
Well.... it IS a whale penis....

But in America, to dork something up, means to mess it all up. Also you can call someone a dork, meaning they are nerds, very pocket protector thick glasses etcetc.

In this example never dork memeory, that means it never lets the memory get all messed up.

Do not read too much into the name for it...... but it IS odd they used a colorful metaphore for it.

Another update, not doing anything else, when I got to work the ram showed 21.9 meg free... up from the 20 earlier reported. I can also see the memory return when I close programs, almost within 1-2 seconds.
[General Topics] madkat:
I have a hunch that normally WM2003 will try to keep the available memory the same, so when you close an app, you don't "lose" that memory - the boundary is just moved so that it becomes storage memory instead.
[General Topics] thaihugo:
My theory would be the following, if the parrameter actually work: If you close a program using the memory pannel, it will close nicelly, giving back it's memory, except maybe a few leaks.

On the other side, using a close button, either spb pocket plus or any free alternative, usually leave a lot of memory out of the loop, making huge system memory consumption. I guess this paramter is dealing differently with memory in this case, and reclaim it in a way it doesn't leave all this chunk unmannaged.

Of course, this is what I "feel" by doing my everyday actions. It could also be because I've installed a new version fo softick card export or pocket informant, and those are not blocking memory program anymore. But I still think the parameter is playing a role. We need more confirmation out there.

BTW thanks for the explaination about dork.
[General Topics] tweakradje:
Thanks for all the feedback and explanation of dorking. Realy useful.

- The key comes from any wm2003/se OS.

- I think now, as said before, that it locks the memory slider in place

If the key is not set at least 2 functions are called from shell32.exe

that have to do with setting the memory division Storage<>RAM:

GetSystemMemoryDivision and SetSystemMemoryDivision

Thanks again for hunting this down with me.

The easiest way of finding keys like this is to get a util

from www.sysinternals.com called STRINGS.EXE.

usage: STRINGS.EXE -u shell32.exe > shell32.exe.txt

-u stands for Unicode (strings like 00 52 00 52 00 62 00 00)

The normal Find.exe won't look for these unicode strings.

Cheers
[General Topics] ZeBoxx:
I just use Total Commander and use its regex search ;)

Problem is, even when you know an app is accessing a particular key, it might not even be in the app's files in a unicode way as the exe/dll/whatever may be compressed. poo on that :)
[General Topics] madkat:
I used a Hex editor which has Unicode search functionality. Searched in both files in both ASCII and Unicode. Your code with MemoryDivision calls made me think it must have something to do with that slider, and that was confirmed by the call missing in Windows Mobile 5 :-)
[General Topics] tweakradje:
Absolutely right. But the presence of a key or value is a start.

I use IDA (demo mode) for decompiling the file in question to get more info. It is still a pitty that sysinternals don't do regmon for CE. I've asked them on some occasions but the answer was now every time.

A unicode string search can be a good start.

From shell32.exe:

PowrPass

ControlPanel\Owner

HHTaskBar

ulacky.dll

IgnoreExternal

Software\Microsoft\Bluetooth\Settings

Software\Microsoft\Shell\NeverDorkMemory

I also use it for Windows dll's and exe's to get more info.

Or for this:

More updates....

I have now been using my mda now for ..... all daypretty much with up to like 6 programs open at once....

After closding them, I still maintain about 23-26! meg free.... which is much better than the usual 19 I get without this key.

Not sure if it is supposed to have this effect, but it very much has thus far on my mda wizard. Combine that with sktools free ram and I have about 27 meg free.

I also found that taking the device lock today icon off, saves almost 2 meg ram.... anyone know why?
[General Topics] madkat:
Read some of my posts further up this page - see if you can understand what it's actually doing. (BTW, I was completely right.)

It's to do with automatic allocation of memory between storage & program memory. The amount of memory you have free is largely immaterial to how well your device runs, and provided you have free storage space, your program memory will actually *increase* on its own when it starts to run low, *UNLESS* you've implemented this "hack" (with - as stated - a DWORD value of 1)

If you implemented it and it has no value (or 0,) you're simply experiencing the Placebo effect.

To my regret I can confirm BtT's post. I do have a WM2K3 device & the memory slider is completely frozen when this key is present. I noticed it this weekend, when I had serious program memory pressure, while there was plenty storage ram left. All programs just freezed, till I managed to move the slider a little to gain more program ram. Now I deleted the key the slider automatically adjusts again & the device remains usable.

Judge for yourselfs, but I'm convinced. This tweak: not on my device.

[General Topics] levenum:
I wasn't paying much attention to this thread until I saw BeyondtheTech's post on what the key actually does. As a WM 2003 user, and a device that is a bit short in memory department (only 32 MB) this is great for me as I had memory heavy programs crash many times (some times causing the device to lock up) not because there wasn't enough memory, but because the system allocated to much for storage.

I know most people have WM5 these days, but if there are some folks out there who think it might be a good idea to add a setting item that will control this option, PM me. If I get a dozen requests or so I will write it and post here. (I wanted to try writing a cpl for a while so this is a excuse)

If you run out of memory (I have in the past) just go & adjust the slider. If you fix the slider in place with NeverDorkMemory, you'll only find yourself running out sooner.

Now the official explanation to how it works in Windows Mobile 5 8)
[General Topics] tweakradje:
The Key is not present in the SHELL32.EXE from Wm2005 (as told).

But has anybody tried to find all the strings in the SHELL32.EXE (or .dll?) for WM2005?

Perhaps some likewise jewels (or many others) are there to be discovered. Anybody working on this?

If anyone can post a ZIP with that file from WM2005 I will take a look into it.

(funny that there are still things to discover / undocumented in MicroSoft software ;O)

Cheers
[General Topics] levenum:
Actually, on my device (HP iPaq 1710) the slider is useless under normal conditions (I've seen this behavior on other WM 2003 devices). Couple of seconds after I adjust it, the system resets it to half the memory between storage and program. Even if I don't click ok on the dialog it still returns to the original values before I can launch any program.

With the key the slider is

not

locked, I can move it as I please and the system doesn't touch it.
[General Topics] Rudegar:
the fact that a key is missing in windows dont mean that it will not be used and work if you put it in yourself using the correct name and type
[General Topics] tweakradje:
This is common. Don't set it too much to the left. When set too much to the left it will jump back. Also there seems to be a 3 or 4 seconds time window in which you can set it. If you are not in sync with that than it also fails.

Ofcourse the NEVERDORKMEMORY avoids the system to fiddle with it.

Cheers
[General Topics] oltp:
My problem with it is that usually I want more ram for the programs, sometimes when I take some snapshots I need more storage ram cause it's simply the fastest type of memory available. Since I don't likevthe move the slider each time, I will forget it too you know ;-), I want it to adjust itself & that's default.

Okay

So far what is known and what was given is an explanantion of what it does & how it operates in WM2003...

There is no facts on how this key interacts with the WM05 OS because the big shots dissmiss the issue all together.

I would like to know if the key causes ANY effect on the system, causing it todo anything. Does it call the WM05 system to "look" or refresh or do anything in the process?

This has not been answered. Only a statement that ideally , it should not do anything in WM05.

Thats like saying, OK I can put any key from 2003OS into my WM05 OS and nothing will happen :p

We all now that messing with the registry can cause problems, so actually we could have worsened effects if this was a critical key!

I would hope that the 05 OS does not have any undesirable lingering 03 behaviors to the updated memory architecture.

I'm only complaining on how little validity and weight the key was given by the "experts" who dismissed it without actually checking it out any interactions. Why do we have todo all the checking?

The past posts in this thread so far proves that there is too much going on in this OS for us to pinpoint causes with this memory usage.

:?

EdIT: I would embrace placebo effect scenario if it was looked into. :shock:

IT DOES NOTHING ON WM5

THERE IS NO CODE IN WINDOWS MOBILE 5 THAT EVEN LOOKS AT THIS REGISTRY KEY

You're welcome to get the ROM yourself and poke around in it for values, but I've already done that. There's no more to investigate.

This seems to be a typical reaction amongst non-techies. They seem to thing we just dismiss things after a quick glance and spend the rest of our time sat on our backsides doing nothing. Had it not occurred to you that some of us are actually good enough at this stuff to come to such conclusions after a couple of hours, rather than a couple of weeks?
[General Topics] Goldry:
For what it's worth...

I tried my Himalaya (running TofClock's 2.01.64WWE) for a week with NeverDorkMemory. As far as I could tell it made no difference at all to the running of WM5. There was no appreciable change in speed or memory available - but on the positive side it didn't make the device crash.

So, based on my limited experience of it, I'd concur with what others in this thread have said: it makes no difference at all if you're running WM5.
