Hi all,
Actually I looked around for a while but couldn't find any topic related to this story.
I have bought a Bluebo B9500 chinese phone and been using it for a while now. To be honest, it is not that bad except the fact that some ROM's show a fake hardware config. CPU, board name, resolution, storage capacity and sensors are all fake!! nothing really bad so far but the worst is coming... My real problem is with the RAM. even the RAM was fake! showing 2GB of usable ram when the real hardware is only 512MB.
As a consequence, when the used ram grows bigger than the real (available) physical ram, some apps start crashing, restarting and acting weird.
I downloaded few kernels for this phone and luckily one of them was telling the truth about the RAM but got some troubles with the digitizer.
So..
My idea was to decompress both boot.img files and put the healthy ramdisk and kernel.img parts together and drop the sick ones to get a working boot.img file. I proceeded with my idea and used some tools that i've found here in the forum but when i flashed the .IMG, the phone couldn't start again.
It doesn't even show the boot logo.
Any idea or any useful hint about how to get the correct RAM in my kernel?
Thanks a lot
hi, i have the same problem, how can i fix it ?
thanks.
Hi, have you been able to fix this problem. I'm arguing about RAM and camera resolution with the seller of my B9500. I've also got problems with the touchscreen / digitizer.

Hey guys i think this should be an important challenge to overcome maybe find out where all the ram is going and get it back without reseting our precious moguls. My experience its something that Task manager doesn't show up because when i end task on my DCD 3 1 2 ROM i dont get all of my memory back like right after reset. Also this causes inconvinient problem of starting GPS after few days of RAM going down to 8mb and not having enough to lunch TOMTOM.
Oxios doesn't not regain full mem only one third of it.
Can we some how make a better task manager or maybe purge RAM?
Writing a driver to consider our FLASH cards as constant RAM?
I would gladly sacrifice remove ability of my MicroSD for extra 4 gigs of ram and would let my memory leak on a period of roughly 4 years of constant usage.
Please lets get organized and stop hoping the next ROM upgrade will solve this issue.
This is one of the biggest downfalls of the mogul
I would suggest looking into how RAM works before making this thread.
First off, most of our ram appears to be lost due to memory leaks.
http://en.wikipedia.org/wiki/Memory_leak
And since, at least in my experience, most of the memory leak comes from Windows 6 (and so much worse in 6.1), you can't exactly end the windows task unless you...
restart the Mogul.
So no, an application, or task manager, wont do you any good. Not until they fix windows 6.1 up to not be lord of memory leaks. That is why new roms are often so desired, because only a rom release with some decent version of 6.1 with hopefully some patched memory leak holes could help our problem.
Second, you can't use a flash drive as ram, at least its not reasonable. You think the Mogul slows down now? Wow, just wait to you see it moving at the blistering pace of a microSD card.
Ram is so small, and so expensive, largely due to its speed. Thats why you can buy a 500GB HD for about the cost of 4GB of RAM on your computer.
Also, running from the MicroSD would be similar to the page file on your home computer. It runs from, in most cases, your C drive, its a fairly large file, getting even larger when you run multiple tasks on a low RAM system.
It is slow as a dog, and is one of the worst causes of system slowdowns. I also believe that MicroSD's have a limited number of read/writes. While not an issue so much for everyday use (taking pictures, running an app from time to time), if it were used as a swap file, it would probably wear out that SD card pretty quick.
So no, short of an amazing, simple amazing, piece of software engineering on Microsoft's part on a new Windows Mobile, someone developing some sweet, easy to install ram upgrade, or the new replacement for the Mogul coming out with more ram than we know what to do with.
You will be restarting your Mogul.
It should be possible to wright a Driver to USE RAM for swap file and some of main drivers but MicroSD card to be used to run all the extra features and programs. Also why our team of coders cant plug the memory leaks or find out the runing programs not seen by Task manager and have option to close them?
PS
Thanks for confirming my worst dream about the limits of our mogul. Also I notice that PPC on palm trios seems not to have these memory leaks.
This is maybe possible if we can build a tool that can reboot the shell without rebooting the actual OS. It can be combined with the command to free the memory when the OS is unloaded. This is my theory, i think that we can recover memory like this

while every single statement you say is true, your only wrong about how long ti takes to wear out a flash device. According to Toshiba, the inventor of Flash memory and one of the top suppliers of Flash memory chips, the 10,000 cycles of MLC [Multi-Level Cell] NAND is more than sufficient for a wide range of consumer applications, from storing documents to digital photos. For example, if a 256-MB MLC NAND Flash-based card can typically store 250 pictures from a 4-megapixel camera (a conservative estimate), its 10,000 write/erase cycles, combined with wear-leveling algorithms in the controller, will enable the user to store and/or view approximately 2.5 million pictures within the expected useful life of the card.
For USB flash drives, Toshiba calculated that a 10,000 write cycle endurance would enable customers to completely write and erase the entire contents once per day for 27 years, well beyond the life of the hardware.
take into note that is only 10,000 write cycles. 100,000 which is common for most flash drive now a days. so no, he wont even be around to see the day his flash drive even wears out. LOL.
Glad to see this post picking up some steam But lets Try and focus on making A solution rather than discussin known facts
the known facts have already pointed out the problem (memory leaks in the OS) and the only solution we have without the source code (restart the OS by rebooting the phone) so what else is there to discuss?
oh yeah, we can talk about ways to get the source code so we can fix it.
well i posted one idea:

Hi all. Today i have disassemled my Diamond2 (I have looking for reason why it have 288mb of RAM)
And found interesting thing:
Diamond2 have only 1module of memory, it's Samsung (I have recorded markers on the chip but have lost the papper.. ****)
i have COMPLETELY disassemled the phone, i found only ONE module of ram (For example my previous phone had two pieces)
So i think HTC did this:
They merged nonvolatile slow 1024mb module for:
1)512mb for internal storage
2)288mb for RAM
3)Anoter 224mb has been hidden
Its explains how HTC got 288mb for RAM, also explains why Diamond2 3(!)times slower than SE X1 in memory bandwith benchmark (nonvolatile memory not so fast as traditional RAM module).
So i think its possible to get more RAM by editing rom's memory mapping. Actually i can't do it by myself, but is there someone who can do it? I can test "New gen roms" in my spare time
P.S. Eventually we can just pump some MB from Storage (Are you need so much?) to RAM (You definitely need it, especially when use rom with Manila2.5)
P.P.S. Why i think its 1024mb module? Because i never ever seen memory chips like 768mb
good idea.
sadly that I don't know any thing about technics.
looking forward that some guys will make it.
BUMP.
I would love to see this come about!
The module is:
SAMSUNG 967 KBY00N00HM-A448 GML215A7.
Checked with google, didnt find how large it are, but its really nonvolatile memory, also very cheap
Interesting
+1
I always wondered about this. Would be nice if someone could pull this off. Mine starts up with only about 70mb free (uggggh) and slowly but surely goes down to around 58 where it finally seems to stable out at.
Interressed too !
that's quite some smarts digging this up!
will keep checking here for the holy grail of more memory...
I only wish that its possible to do it.
we all are much interessted , but search the developer... i dont know it if works, I mean the topaz is already 1year old , i can't believe that nobody have try this already...
but i hope =D
maybe a radio update will do the trick, like it did on the HD2
Possible beginning of a solution
If it is a 1024MB chip then maybe they simply laser cut a connection somewhere giving access to the rest of the available memory.... Like AMD did on the old Athlon chips to lock the multiplier.
If this is the case then all that's needed is a graphite pencil and the location of the cut connection and we're in business!
except that AMD CPU was on a large peace of PCB, and the connection was easily in sight, while here we're talking about a possible 65 nm technology memory chip completely encapsulated. good luck using a pencil on that. sorry I'm such a show stopper, but it's gotta be somewhere else.
This is a memory module, not an old athlon CPU
Have found a little guide from Loox device:
1) Patch nk.exe ("ulRAMEnd" must read value from ROMHDR, not an constant)
2) Patch nk.exe (Dont let "IPM-functions" in nk.exe rewrite registers in memory controller and activte additional RAM partitions.
3) Change "ulRAMEnd" in ROMHDR, XIP partitions.
4) Edit "OEMAddressTable" in nk.exe.
Just realized, we can try to change "MainMemoryEndAddress" in nk.exe (S000 file). It works for Kaiser/Polaris/Niki, gains 16mb of RAM
This is Great!!! If there is a possible way to do this then our TD2's will run much better and faster
and then if only we can overclock damn processor...
Have checked situation about HD2 hidden ram and found that it actually same with D2 - HD2 also have only one memory module, it doesnt have real RAM memory too.
So it was possible to resize RAM partition by flashing new rom and radio(?).
So i 100% sure it can be done on topaz.
(By the way i think Diamond, TP and Rhodium affected too cause they all got very slow RAM with strange size)
I dont have PC so i cant do it by myself
So our hope is cookers only, or someone like Olinex
P.S. Can someone send me nk.exe from HD2 original and new (With unlocked RAM) roms?
Interesting find! I'm following this with excitement hopefully someone can do something about this... but then thinking about it isn't some of this extra RAM saved for hard resetting by the bootloader?? Getting rid of this will stop that or am I confusing this with the ROM space?

You should also post this in the HD2 ROM Development thread, hopefully someone will send you the files.
Also, this thread is getting more and more interesting! I hope you can come up with something!
Best regards

Nope, hard-reset will just delete all files on main storage that doesnt have "ROM" marker. Its the only thing it does and doesnt requires extra ram. (I think so, may be i wrong )
Hello
sorry for bad English speaking
I have a strange problem with my smartphone!
My smart phone have MTK Quad core 1.3Ghz CPU and 1 GB of RAM , that made by Unknown mobile company.
glxphone.ir/en/?portfolio_page=glx-g5
My smart phone have so much lag Even in simple process like scrolling pages despite of Rather good hardware
a group of people whom use this model have similar problem too While others have no problem.
benchmark of normal phones is about 17000
but Troubled phones is about 8000 and CPU Multitasking is poor.
I flash the normal phones firmware on my phone but no change Occurred.
next I flash a custom ROM of G,FIVE G9 phone on my phone then The problem is almost solved and benchmark increased to 14000
but this custom ROM have many bug and isn,t Useful.
Now i want to know how I can solve the Problem in original rom .
Please help me...
thanx
no any idea ?!
can any one tell me how I can change CPU settings (which files)in ROM?
thanks for no reply
Hello XDA, I use an itel it506 android phone which has less than 512mb of RAM and exact 5.5gb of internal storage. Of course anyone seeing this should know how slow the phone can be when it comes to multitasking and playing of some good quality games. I did a research on google on how to increase the RAM of an android phone and got introduced to the app called RAM EXPANDER developed by ROEHSOFT (which increases the ram virtually not physically but using a part of the sdcard as RAM) but after following the tutorials, not just in a particular site but also tutorials from other sites I have no luck , the worse part of it is this, I introduced this same solution to a friend of mine that has the same problem on his tecno phone and it solved his problem making his phone 70% faster according to him. The question is why doesn't it work for my itel? Is it that it doesn't support itel phones or what? Cos I have tried it on my first itel 1501 of the same category of RAM size with this it1506 and no luck also, or is it something I am doing wrong. Please help

This is the wrong subforum, You will need to post in the "other Android devices" subforum to recieve help (I forget the exact name of the subforum, sorry about that).
This subforum is strictly about the Exodus custom ROM, not about miscellanious issues on any device's stock ROM.
OK thanks.. I was even also confused on where to put it cos I didn't see a particular sub forum for posting problems

No problem, perhaps the XDA Assist threads will help you, it's under the General Discussions subforum.
OK thanks a lot, I'll do just that.

Is it still possible to increase the RAM size of the Poco F1? I have the 6gb/128gb variant and I want to have maybe 2 to 4gb more RAM. I read around that it can be done with a swap file on older phones but I already tried that and even added up to 6gb but it doesn't seem to get used. Is there a custom ROM or magisk zip that can be used for that? My phone currently runs on Corvus with NGK.
The reason why I want more RAM? Egg NS. My phone frequently runs out of RAM and the game force closes.
Thanks!

What are these apps and games you use?
How do you fill the entire memory?
I switched to LineageOS + NGK because it's more stable. So far I only have DamonPS2 and Egg NS installed after flashing the ROM. Had no problems with DamonsPS2 even with stock ROM. Anyway, I said before the app in question is Egg NS, a switch emulator. The app needs 8gb RAM so the Poco F1 is short of 2gb that's why it force closes randomly. I get smoother framerates compared to stock but then I still run out of RAM.
Well, short of swapping the DRAM modules for bigger ones it would be impossible, and even then who knows if it would work?
Although now that you've posted this question, I'm left wondering if anyone has successfully done this… I know that Scotty from Strange Parts (and others) have swapped NANDs for bigger storage, but RAM I've never seen.
I think ram is included in the SOC, which means cpu, gpu, controllers, everything else will be also replaced if someone were to upgrade ram, basically changing the core of the phone.
I'm trying to make it work like this one. A really old post from 2012 so I doubt it'll still work for Android 10.

In that case why don't you try zRAM instead? Depending on the kernel your zRAM (or swap, for that matter) capabilities may differ, but give it a go!
IDK about other kernel utility apps, but EX Manager has the options.
Ok I'll give that one a try. Just tried Roehsoft RAM expander and it still works but the game runs really slow when it's already using the swap memory. At least it doesn't force close now. lol
