[Defy Q&A, Help & Troubleshooting] Eneekay:
Hi!

I've had the same problem. Also on MB525, red lense. I have not managed to make it work either. Preinstalling kernel does not work for me. Formatting does not work either.

However, there is a possible solution, which I have not had the time to try out yet, and was suggested to me in this thread:

http://xdaforums.com/showthread.php?t=1782832&page=132

Simply put, you can try flashing a custom SBF with CM10 pre-loaded on it through RSDLite, and then update to the latest versions. Just head over to this thread over here:

http://xdaforums.com/showthread.php?t=1691901

And try with one of the 2nd boot SBFs. I will also be trying this method out shortly. If you manage to get anything done with this method, please report here, so that I know as well!

[Defy Q&A, Help & Troubleshooting] gyorgyszemok:
are you saying that 2ndboot SBFs exist? where have I been? under a rock? my god..

gonna try it in a few days, but i'm scared about the failure as it never worked before, but now you gave me hope thnx. :good:
[Defy Q&A, Help & Troubleshooting] Eneekay:
Even if you fail, you can always wipe/flash an SBF if necessary and revert to your nandroid backup. I might try it today, if I have enough time, but no promises. When you try, please report here.
[Defy Q&A, Help & Troubleshooting] gyorgyszemok:
It seems I have BL version 5, but from an SBF with a size of ~35mb

Each time my phone went so bad I couldn't get to CWM:

-RSD Lite Flash: Éclair (JORDN_U3_97.21.51.sbf)

-Stock Recovery wipe cache, data

-Root

-install 2nd init

-Restore with cwm backup&restore "2011-06-11.14.14.27" which I downloaded from a guide

-Wipe data, cache, dalvik

-Reboot instantly into Bootloader

-RSD Lite Flash: firmware.sbf with CG31.smg version 5 (downloaded from the same site where "2011-06-11.14.14.27" cwm backup was)

-This flash it fast, cuz the firmware.sbf is ~35mb

-Reboots (via RSD Lite) to Froyo and it's rooted...

So, my BL version is...? 5? How important is this?
[Defy Q&A, Help & Troubleshooting] Eneekay:
I started trying out some of the SBFs. From now on I will be reporting everything on this Thread:

[Defy Q&A, Help & Troubleshooting] gyorgyszemok:
It seems like our phones are more alike then the others. Do you usually recover with the fixed sbf and the 2011. dated nandroid backup? whats your cg version? mine's 5. so it's more likely the cause that we have gingerbread CG version...
[Defy Q&A, Help & Troubleshooting] Eneekay:
Yes, I recover the same way you do, and the CG version is the same... This is what I thought as well, that it is because of the Gigerbread CG. I have no idea about any workarounds though...
[Defy Q&A, Help & Troubleshooting] gyorgyszemok:
-But I don't know if we have the Gingerbread CG like many others, why don't they have this problem? I could guess pretty much people recovered their phone the same way like us...

-It must be something about the kernel the CM10 uses, and the CG version! ...or the drive format (ext3,4)?

-I also read about your failures (in the other topic) flashing modded SBFs, so I definitely won't try them until we have a solution.

-Months earlier I found something about this problem (CMX bootloop), and the user could flash 2nd init CMX, but not 2nd boot. I haven't found that entry since then... And neither did I find 2nd init CMX ROMs.. Quarx must have took it down rendering them useless.

Argh! It's just so annoying! Stuck at ICS, the highest ROM available... And that's so buggy! I use Euroskank CM 7.2 now... But it's ugly (was... I modded it...), and it's like mentally disabled compared to a JB rom...

Are there any other JB defy ROMs out there? Which do not rely upon Quarx's build?
[Defy Q&A, Help & Troubleshooting] z3ro-grav1ty:
CM10 uses ext4, in bootmenu (after you press volume down at the blue led during boot) go to tools and then file systems (something like that) then you can format to ext4 (wipes data and cache).

At the moment that's all I can really help you with because my model (defy+) works differently to yours.

All I can recommend is working from stock. Also isn't there a fix for some MB525 models?

Thanks! Will check it out.
[Defy Q&A, Help & Troubleshooting] gyorgyszemok:
I know how to format, but thanks for answering.

It seems the root of the problem comes from the fixed sbf (so called firmware.sbf) with the CG version 5, which does something about downgrading. As stated in the other link we should upgrade to BL7 with a Defy + SBF, but I don't want to make that risk...

SO: The problem, why we can't make CM10 works is that our Defy MB525 has CG31.smg version of 5 from the downgrading fixed SBF!

How to fix that? Should I really upgrade to BL version 7? What can it do with my device?
[Defy Q&A, Help & Troubleshooting] Eneekay:

It seems to me that our beloved Defy is not much worth the trouble anymore... I am staying on CM7 which is amazingly fast and stable, and thinking about grabbing a new Android headset soon...
[Defy Q&A, Help & Troubleshooting] thekguy:
If you've got a red lens, you can upgrade boot loader version, and you'll have to flash a battery fix for gb and ics roms, and jb will work fine without it. If you have a green lens, then you will not be able to use camera with stock. It will work with jb roms though
[Defy Q&A, Help & Troubleshooting] Eneekay:
Bootloader? Could you point us to the right direction?
[Defy Q&A, Help & Troubleshooting] pradeeppk:
You mentioned that the flashing is fast. So i think it may not flash properly. So flash 2 or 3 times with same rom. This happend to my old captivate. Captivate devs suggesting a second flash for their roms. (Only formating was occur during first flash in some devices. Thats why they suggest second flash)

Thanks

If posting an answer, please show features, pros, and cons.

For instance, the cutting solution

-Features: Power cycle to switch between cards

-Pros: Fits two sims into a one sim device

-Cons: Only supports two sims, not all sims can be cut, cutting sims can possible damage card.

I downloaded Easy Installer, got the apk and installed the package. After Go Launcher installs nothing happens. The option to "open" is geryed-out, my only choice is to click "done". After that, Go Launcher doesn't appear in my app list.
[7" Kindle Fire HD Q&A, Help & Troubleshooting] seokhun:
Then that launcher isn't compatible with Android 4.0, or at least with Amazon's OS. Apex, Nova, and ADW works fine.
[7" Kindle Fire HD Q&A, Help & Troubleshooting] zenusr:
I just wanted to confirm that this method creates an icon where I actually boot the launcher? I've considered the non-root methods to install an alternate launcher but it looks like they all are kind of a "soft" install where hitting the home button actually takes you back to the Amazon OS (requiring you to re-open the alt. launcher.)
[7" Kindle Fire HD Q&A, Help & Troubleshooting] seokhun:
You can set it inside the launchers. Nova, for example, allows you to change the function of the home button, when you press it, it asks what launcher is your main one, and when you select Nova, every time you hit the home it will return to Nova.

And yes, it does create an icon in your app drawer.

Hi All

after upgarde from GB to JB (either LEAK / Official), JB seemed Slow. whether to change the partitions on a flash PIT file MB2 / 4 can increase the RAM capacity in JB.

I found a thread where we can change it by using the application PIT "PIT_Magic".

1 GB? ~768MB is enough for me. Though i really think that it can't go over 700+MB.
[Galaxy Ace II Q&A, Help & Troubleshooting] veaceslav:
1 Gb? WTF?

Our device doesn't have true ram? I thought that we have some sort of LDDR2 ram and it's quite different from it's flash NAND.

I think you can't go over installed 768 mb and you can't even reach this number because gpu also use the same ram.

I hope Samsung didn't put the ram on storage because it will wear out like hell. NAND it's not fast, not even prone to multiple write cycles.

Even if you're successful in increasing you ram, you will make something like swap partition on linux. But I highly doubt it will work.

Swap system is not used on mobile devices because NAND wears up too fast.
[Galaxy Ace II Q&A, Help & Troubleshooting] arroyo:
According to this:

http://xdaforums.com/showpost.php?p=35222874&postcount=14

...we do not have LDDR2. There is only 4GB chip named UME300 (IC-NAND Flash Memory, 4 GB, SDIN5D2-4G-944L, BGA, P/N: 1107-002091)

It may be true regarding memory size of ACE 2:

system 1,2 + USB 1,1 + 0,768 + spare for dead cells = 4GB

SIII Mini for example have 1GB RAM and I/O and RAM operations are much much faster. Also there are no 768MB LDDR2 chips on market. Using emmc as low speed LDDR2 substitute is quite common in Samsung devices.
[Galaxy Ace II Q&A, Help & Troubleshooting] pijen:
I thought this was a joke at first when rozyid said we can increase our RAM

so it was 601MB system + 302MB cache + 1,2GB data + 1,1GB usb = ~3,2GB

It will make sense if the remaining is our "RAM"

if somehow someone able to increase this by resizing other partition (/cache maybe?) it would be really nice

And btw, what is the function of /cache? When I checked it using link2sd it wasn't used

But hey, didn't we used another partition /preload in JB? If I'm not wrong it was about 200MB, right? So then it be more than 4GB if we add it to previous calculation

[Galaxy Ace II Q&A, Help & Troubleshooting] veaceslav:
I was very confused when you wrote this. It's absolute non-sense to use NAND as RAM. It will wear in only one month.

They should have at least the most creepy ram, cache or something else that it can be re-writable.

You can have smooth gui with no RAM installed. It's impossible. You can't draw 20000 triangles per frame and having decent framerates without having a ram that it's capable of speed near 1 Gb/s ...

Also usually memory came in banks, 256 Mb banks were usual in the past, so puting 3 banks can give you 768 MB.

@Jamielawther

I would love that fact to be truth, but this diagram is not hardware schematic. It is logical diagram how things push data between elements. Move couple pages further and try to find element for LP-DDR2 on PCB. I did not found one. Also in document 05-GT-I8160-EPLIS-11.pdf you have the list of electrical parts. I did not found SEC Code for anything that could be LP-DDR2.

@veaceslaw

Take a look at PCB in 08-GT-I8160-TSHOO-7.pdf. There are no 3 ram chips there. In fact there is only one 4GB. If they used emmc as a RAM, it won't die in one month. Probably it last for 2 years or more ... after warranty it may die.

In my PC, SSD disk is used as TEMP and cache memory for last 2 years. Still running flawlessly. Every ROM chip has some space left for spare blocks to be used as a replacement for died blocks.

Tough it would be nice to increase ram but it seems impossible

If we have 768mb of ram, it is shared with gpu and other system use

I've read on xda (forgot which thread it was) that gb and ics/jb is handling the ram usage in different approach, in gb the hardware and system reserved ram usage isn't exposed to user, but in ics/jb some of them are moved so looks that the ram looks bigger

In ics/jb ram looks bigger but it is system reserved so we can't use them

My previous phone, xperia ray, it have ~351mb ram in ics/jb (cm10), but the fxp team removed the ability to record video at 720p (video encoding) because it was choppy and then we have 361mb ram in exchange

You can bring a lot images with tear-downs and stuff but I can tell you one thing: We are not back in 2000 when screens were 240x160 max and with no 3D apps.

Let's assume that your CPU can work with slow HDD like emmc, but GPU can't. It's internal cache of 256Kb is not enough for amount of textures and data to store. GPU is the most RAM dependent part. And can't perform without RAM, ever. In every build from the beginning of computers, GPU relied on the fastest RAM possible to increase performance.

The fact that you can see the chip, doesn't mean it doesn't exist. I see Samsung can pack SLC and MLC memory in one package, probably they did it with RAM as well.

I googled RAM as emmc and didn't find any relevant search entry on this topic, because it's an utter non-sense.

http://elinux.org/images/4/41/Linux_on_eMMC-_Optimizing_For_Performance.pdf

RAM do a lot of writes, as I told you before, eMMC is bad with writes, and also 200 IOPs are pathetic.

Other thing is that RAM should be volatile, because it store you personal data and passwords. eMMC is not volatile and it's hundred times slower than usual RAM.

I recommend you to read "Computer Organization and Design" and "Operating Systems Concept" books if you want to understand how it works so you won't came up with crazy concepts.
