yeah i set frequency to 600 MHz while mounting the system partition. Bdw its fine. Something may happen with the ROM. NO PROBLEM DUE TO KERNEL. check above post, i attached recovery log.

And how can we know accurately that there is any bad block or not. I used recovery log but it not shows in detail.
[HTC Pico (Explorer)] cute_prince:
Reboot your ROM. Once rebooted get me a dmesg.
[HTC Pico (Explorer)] @rcane:
hmm i reflashed other ROM in hurry.. So can't get u a full dmesg but i had took one i am uploading here. Hope it have the information that u need.
[HTC Pico (Explorer)] ateeq72:
bro.. i followed all the steps again but it still didnt work!..

and strange this is i followed this guide with 2.6.x kernel on minimilised rom (cm9) and it booted properly i.e it actually used both the partitions as intented but this never happens with 3.0.x kernel! it always ends up with 'htc' flash screen cycle!

can you please upload your working .config file? :)
[HTC Pico (Explorer)] cute_prince:
Oh man, you are mounting the system partition as writable from the booting process itself :eek:

[ 7.480834] yaffs: dev is 32505859 name is "mtdblock3" [COLOR="Red"]rw[/COLOR]

Find that line mount yaffs2 mtd@system /system rw remount in init.rc and change it to mount yaffs2 mtd@system /system ro remount
[HTC Pico (Explorer)] @rcane:
ohhh.. :crying:

so it cause the problem. Thanx a lot for quick help quick reply.

AND ONE SUGGESTION ADD THIS THING IN OP SO OTHER PEOPLE DONT HAVE PROBLEM. i check inti.rc its by default mounted as rw. changing it. and yeah i revived my partitions. Only DATA partition hve bad blocks. System partion is safe.

[MENTION=4649424]cute_prince[/MENTION]

Can we hack the mtd driver or I/O scheduler to disable the oc when there is some write request to nand and restore it when the request is completed? Or will this degrade performance due to the 50 microsecond delay udelay(50) when switching pll?
[HTC Pico (Explorer)] cute_prince:
Sure :) Download the attachment. Rename pico_defconfig.txt to pico_defconfig and compile.
[HTC Pico (Explorer)] cute_prince:
If SD-DATA got bad blocks, be sure to format that partition before re-use.
[HTC Pico (Explorer)] cute_prince:
Sounds good :) Let's see if we can implement that. I dont think there will be any noticeable performance degradation.

[MENTION=793709]cuteprince[/MENTION] i'm trying to implement this in sense 4.But the ROM never boots please take a look at the following

Logcat:http://pastebin.com/UVuksC3H

My init.rc:http://www.mediafire.com/view/bd6xq4xdrv3wb8z/init.rc

Also attached the screenshots of the partitions..
[HTC Pico (Explorer)] Saumitra Yadav:
Bro Actually The partitions in this pic contains three partitions:-

1. Sd-Ext:- to store the system apps of sense4.1(Yoy Dont need to create it when using AOSP roms)

2. SD-DATA:- This is the partition Which will be mounted as your internal memory(nand)

3. SD-CACHE- To store the cache of apps in Sdcard

[MENTION=4649424]cute_prince[/MENTION]: plz specify in the pic that the extra Sd-Ext is for sense roms only :) If i am Wrong Then Correct me :)

[MENTION=4787368]ramprasad5394[/MENTION] [MENTION=4406555]ateeq72[/MENTION] : Bro Make The Partition in This Order Sdcard(Fat 32)>SD-DATA(ext4)>SD-CACHE(ext4) AGAIN :p

Now While Flashing The Rom:(Follow This Procedure)

1. DONT DO A FACTORY RESET

2. Goto mounts and storage and format everything except Sdcard and and SD-ext :)

3. Wipe Dalvik cache.

4. Then Flash Rom,flash gapps, flash kernel :) Reboot the phone after first boot :)

Note: I followed the above method on a classs4 Sdcard 4 gb and the rom booted in first try :)

Ps:- I am using 878MHz oc Since yesterday not even a single reboot on cm10.1(class 4, 4 gb sdcard) :p

[HTC Pico (Explorer)] cute_prince:
Checked your init.rc. Derefas is mounting and using partitions in different way. You can see the script right inside his init.rc ##############SUPER SD-EXT SCRIPT BY DEREFAS##########

# Linking app_s to system

mount -o remount,rw /system

if [ ! -d "/system/app" ];

then

mkdir /system/app

chmod 755 /system/app

chown root.root /system/app

fi;

chmod 755 /sd-ext/app_s

chown root.root /sd-ext/app_s

mount -o bind /sd-ext/app_s /system/app

Derefas ROM needs many changes to work with my procedure.
[HTC Pico (Explorer)] abhinavthms:
The intention is to just link /system/app to sd-ext/app...

Can you provide a script for doing that.. i don't think any other modification is necessary.

Also that sd-ext script was copied from init.d to init.rc by me....
[HTC Pico (Explorer)] cute_prince:
No need of init.d script. I do that via the updater-script while flashing itself:

ui_print("Linking /sd-ext contents to /system");

ui_print("-----------------------------------");

symlink("/sd-ext/app", "/system/app");
[HTC Pico (Explorer)] abhinavthms:
okay so in my case : i type

symlink("/sd-ext/app_s", "/system/app");

Right?...
[HTC Pico (Explorer)] cute_prince:
Yes.
[HTC Pico (Explorer)] ateeq72:
thanks bro :) gona compile now .. and i will report you soon! :P

edit:

bro when compiling using this config i get this error :(
[HTC Pico (Explorer)] @rcane:
I changed as u said. but still system partition is mounting as RW. Here is the dmesg.

I think it should be mount yaffs2 mtd@system /system ro
[HTC Pico (Explorer)] abhinavthms:
You were right bro no need of that init.d script... i booted sense 4 without that init.d script..:good:

Next trying to implement your procedure in this rom...
[HTC Pico (Explorer)] <JohnCarter>:
DO these steps--

-Open the defconfig

-search for cable

-make the next few lines like this

# CONFIG_CABLE_DETECT_8X55 is not set
# CONFIG_CABLE_DETECT_ACCESSORY is not set
# CONFIG_CABLE_DETECT_ACCESSORY_BY_ADC is not set

-save the defconfig and you're good to go

[HTC Pico (Explorer)] abhinavthms:
[MENTION=793709]cuteprince[/MENTION] if we can symlink anything from the updater script then why do we need memory scripts?.....

I have now symlinked /data/app and /data/dalvik-cache to sd-ext and the rom is running fine....:highfive:

Just cut out a lot of loss in boot.So then why can't we just symlink everything, instead of using memory scripts...
[HTC Pico (Explorer)] cute_prince:
That is what I have done in my Sense 4.1 ROM. I symlinked everything from updater-script itself. No need to use memory script ****s.

Dude I am using cm10 at 872mhz in performance mode for almost 3 days. I have made ext2 partition(class 4) and I m using it as data along with phones internal data(int2ext). Didn't find anything to be lagging. Is it necessary to follow your steps?
[HTC Pico (Explorer)] cute_prince:
Yes. If you are using phones internal data ( the userdata partition in NAND ) along with ext2 partition, then your NAND is already burned. Your are not noticing the effect because of ext2 partition. Just take a look at kernel dmesg and you can see a list of Bad Block messages in it. Also, if you have not created a dedicated cache partition in SDcard, then your cache partition in NAND is also damaged (burned). Soon your NAND will be irrecoveribly damaged. Either revert OCing or use a dedicated partition for storing userdata and cache in SDcard as I have suggested.

This guide is for devices with unlocked bootloaders
[HTC Pico (Explorer)] cute_prince:
[MENTION=5048809]artistaditya[/MENTION]

LBDAF => Large Block Device And Files. This configuration is required for mounting more than one ext2/3/4 partitions from SDcard. Without this option, you can mount only the very first ext2/3/4 partition (mmcblk0p2).

To disable GPU OC, open devices-msm7x27a.c and locate the structure static struct kgsl_device_platform_data kgsl_3d0_pdata = { and delete the structure and its body completely. Now add following code there:

static struct kgsl_device_platform_data kgsl_3d0_pdata = {
.pwrlevel = {
{
.gpu_freq = 245760000,
.bus_freq = 200000000,

No. The RamDisk used in Build#2 and Build#1 are different. If you want OC, then unpack boot.img from Build#1 and replace its zImage with zImage from Build#2. Now repack and flash it. Also, make the required 3 partitions in SDcard.
[HTC Pico (Explorer)] wmapt:
Why not use same ext partition for data, cache and sd-ext mounting in different dir?

Or 1 ext part. for data & cache and 2'th partition for sd-ext or.. different combination.

Then we don't need:

- different partition scheme for sense based rom and cm based rom's;

- different recovery.

Maybe I am wrong
[HTC Pico (Explorer)] IronFistYo:
It is not an option provided in Linux kernel. Only the partitions can be mounted, not the directories.

A possibility maybe making a small 2nd and 3rd partition and symlinking it with the first partition. (Maybe)

this method has saved mass of space of internal memory,so why spare the saved space to enlarge the cache partion in the nand,

then we just need to make a data partion in addition from sdcard without partioning cache-ext.

It is clearly mentioned that the nand burns when the data and cache partitions are mounted as writable.

Epic Bump :P

Now, if you'd see, since CM10.2, the system apps' dalvik-cache became somewhat small to fit into /cache partition. This was the major cause of FC's. Until someone (idk if it was joilaroi, or sakindia123) decided to move this into /data.

This is done using this line, in build.prop:

dalvik.vm.dexopt-data-only=1

So, whatever files are created, are created *only* in /data, and /cache partition is totally unused.

So therefore, we needn't be worrying about frying the /cache partition (it wouldn't happen as we ain't reading it?). Hence, just reverse-mounting the /data partition (using scripts like "int2ext" (not "int2ext+")) is enough. Also, to *not* worry about the /cache partition, we could mount it as RO, by adding a few lines to script ;)

I like Ram stuff, but the only mount they have that works with the LGOG looks like it would stick out in front of the screen, and possibly press the side buttons... there's a really nice form-fitting mount for the Nexus 4, but nothing for the LGOG specifically.

Are there any generic holders that people really like? Money isn't much of a deciding factor, I want something slim, that won't allow the phone to wiggle around (even off-road).

Thanks!

GM everybody,

I cannot post yet in the development forum so I have to make it here in the Q&A section.

I've installed the CM10.1 TWRP and, with the exception of the known issues, the ROM works (quite) perfectly.

Some people complains that screen auto-rotation often stops working for some reason and a reset is necessary. I never met such issue till last sunday when I've downloaded and installed from Play Google Maps with Navigator.

Once installed and started maps and/or Navigator, after a while autorotation freezes in portrait or Landscape mode depending on the latest usage for the application. To fix that you must restart the device, I haven't been able to reset the accelerometer in other ways.

Yesterday, after the n-th hang for autorotation I tried cleaning the Dalvik-Cache and system cache from TWRP but again using Maps for a hilw autorotation stopped to work again.

The only way to fix it has been to remove Maps from the device...probably it is enough to do not open it at all.

Did somebody else experience the same issue?
[Galaxy Tab Q&A, Help & Troubleshooting] albe1974:
Wow, 183 reads and no answer.

Btw, the ptoblem looks to be Google Maps.

No idea on why it males rotation stuck.
