The first step is to replace the faulty stock ICS kernel.

If you are not in stock ICS or you have already installed a custom kernel, you don't have to flash twice.

I don't know which stock ICS is good or bad. Just don't want to risk.

Factory reset usually wipe /data & /cache

PA or CM rom will write to /system & /boot

stock rom will write to /modem & other partitions too.

standard stock rom is in .tar.md5 format. and each partition is an image which will replace the whole partitions.

if you are in boot loop and can't be fixed by factory reset. There may be something wrong with other partiition(s). By installing stock rom will probably reset it.

As I mentioned before, pa & cm (and most of other custom roms) only touch /system & /boot. When to do factory reset, wiping caches doesn't matter. You may also redo it after rom boot and no need to re-flash rom/gapps.

Although this is not a good pratice, I sometime don't do factory reset when flash new rom. If something goes wrong, I can redo it. When I go from CM10.1 to PA2.99, I didn't do a factory reset. Found out that everything is preserved.

If you don't know what you are doing, play by the book is always the secure way.

A backup in recovery is a MUST if you flash alot.

Where can we find birck safe ICS kernel?My stock ICS is P6810XXLPM_P6810OXXLP1_AUT.zip, that I use to flash.Its from samfirmware.com.May be its kernel is safe, because there was no problem with it, so far.I am an average user, thats why I try to keep what it is in written.Whether what cause bootloops in PA roms?I made TWRP backup, other method was not sucessfully as we discussed it before.I just hope it will work for restore when I need it.

It is worrisome that even such an expert like you can make brick.Sure accidents everytime happen.Do you know already what was led to brick for your tab?
[Galaxy Tab 7.7 Android Development] Alcibiade:
This ROM looks tempting... :)

Anyone cn comment about the battery life vs a Stock ROM?
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
CM 10 and CM10.1 always scores 30% less performance in all the Benchmarks i have tried. and also if you can't achieve the required performance that means you use more battery to achieve the same processing amount.

also, the main advantage in JB is its smoothness and this requires Battery smooth to fully work. and so far it's not achieved

Also as tried as i know cm 10 doesn't use hw decoding when playing videos.

the changes in the Sammy's kernel i have noticed is in some drivers, i didn't look at all the code.

you can use "beyond compare" tool to compare code files.

if you can boot it up with the platform compiled, then you can later add modules from other tablets like multi window, page buddy, smart stay ... etc.

The modification in the Kernel to get it work is just some driver configuration and dpi changes, and it's minor not a lot.

It requires trials and patience and i'm sure you can get it work.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Don't know which benchmarks are you used? 30%!?

I got 98xx in antutu for cm10.1 & 93xx in cm10 & pa2.55. With the same Antutu 3.1.2 & 3.2. I got 79xx in stock4.0.4 82xx in stock 3.2. But after using an oc ICS kernel which can be boosted to 87xx. The results may vary and I always test it 2 or 3 times right after flashing with no other apps but gapps. May be other apps in stock rom decrease the performance but I don't think it is significant. I'm quite sure that stock JB is faster the ICS. May be someone have a N7000 tell us the differences.

I'm looking at the XXLSZ and ZSLL4 source from opensource.samsung. I don't know which source you are looking at. Can you give me the link?

I observe some changes in the source but it is mainly for passing the build of 4.1.2. These changes are already done in CM's kernels. The only new thing is mali video driver 3p1 (also include in CM's kernel now) which is not working on p6800 yet.

Even so, the drivers are working fine in CM10 & pa255. The only thing left is built-in wifi tethering. I have already look at the wifi part in the source. There are some differences but not related to tethering in my knowledge.

The other thing is hw decode for audio. Video has hw decode in CM10. I've test several players, MX, Dice, Mobo... Yes, some might need to turn off hw decode for audio. Again, I found no observable issue for replay.

For those proprietory apps from Samsung. I'm not quite interested but someone in our local forum said he can make multi-window works on CM10. And I think it is possible.

I might look into it when I have time but really no motivation now. If you are interested, you can PM me. I'll tell you what I know to start with.

phone and BT doesn't work, and i rely on the tab as phone sadly.

so waiting for phone to work.
[Galaxy Tab 7.7 Android Development] daniel_hk:
In case someone else also interested, I repeat it here.

Firstofall, you need to know how to build an AOSP rom.The following is a good place to start.

http://source.android.com/source/initializing.html

Going through the getting start part

Form

Initializing the Build Environment

To:

Building Kernels

I've tried Ubuntu 12.04 and 12.10. Both work properly but I use Ubuntu 12.04 most of the time.

A better PC is essential. My dual core E2140 3G ram system required 3hrs.+ for a clean build! I really need an upgrade!

Try building an existing device first. You'll get the idea how it work. For device not supported by AOSP is quite difficult.

With the source of N7000 from samsung, you can only do it seperately. The otapackage may not apply here.

Follow the README's inside the source. It give you a brief idea but the output will not boot.

1. kernel

To build a bootable kernel for p6800, many tutorials but this one actually work for us:

http://xdaforums.com/showthread.php?t=1846916

but you don't have to follow everything.

You have built an AOSP rom so you already have the building environment and cross compiler.

to config p6800, use:

make p8_defconfig

Build the kernel first. It won't boot, don't bother to try. A boot.img require kernel+initramfs.

Now is the harder part, build your own initramfs for JB. You can start with the one in ICS. You can unpack it from the existing ICS kernel. I suggest you unpack the initramfs from N7000 JB too. You can compare the files and try to make a workable one for p6800 JB.

You need to modify the init.rc and/or other *.rc files.

After that, rebuit the kernel with the initramfs path added in .config and the modules placed in lib/modules. Now you have a kernel and hope it may boot. You may need to rebuild it after the platform is built.

2. Platform

replace the corresponding projects/files of AOSP source with the one form samsung's source. Now you build the platform again. Hopefully, everything go well but you will not get a rom. You will get some directories in the out path. Now you may work with those files in /system. which is the core you may find in any rom.

The make file samsung give do not use neon which is much faster. You may need to change it afterward.

the out/root directory is actually the initramfs but the content is for an emulator. You can study them when building your own initramfs.

Together with the kernel, you can write an (or better modify an existing) update-script for rom installation. Pack it with the kernel and you are ready to flash.

possible problems:

1) if the rom stuck at Samsung Logo. -> kernel not decompressed or run properly.

2) Stuck at black screen after Samsung Logo disappeared. -> kernel is running but with driver or other issues. You may probably connect to adb if your *.rc is config properly.

3) Stuck at boot animation.(even the emulator has a boot animation of the letters "android") -> This is the best scenario, your kernel is boot but stuck at framework. Your real work starts now.

This is a hell of jobs that really needs patience.

Goodluck!

AW: [ROM][p6800/p6810/i815] (11/3/2013 cm10.1 update) Jellybean Custom ROMs & CWM

First of all I'd like to say THANK YOU to daniel_hk and Iocerra for doing all the hard (and successful) work for keeping our (especially my ;) ) great GT-P6800 alive.

I am very happy that I can use Google Now! now ;) and that it runs VERY STABLE. I am running lots of business Apps with it (e.g. Exchange, Citrix, etc.).

The only thing I am missing is BT so that I cant use my Wedge keyboard and mouse and that the original Samsung keyboard dock isnt working correctly without external keyboard helper (I need the german layout) anymore. But thats OK for me.

BTW - my Quadrant Score is 3339.

regards

Is voice search broken in CM10.1? Using 3/3 build
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah! Just check. Same happen to sound recording.

Audio service can't start properly. Never change that part, may be cause by Bluetooth. This may also cause the phone apk FC. Will definitely look into it later.

Thanks!
[Galaxy Tab 7.7 Android Development] wintermute000:
No big deal Daniel this ROM is already good enough for daily driver :good:

It still has the wifi sleep of death but UNLIKE 2.55 you can work around it by telling wifi to sleep when idling (i.e. keep connection never), then it behaves properly - in 2.55 the sleep of death would hit whether you turned off wifi on idle or not. So I'm more than happy thanks to your hard work!!!

(but lord the phablet layout is annoying!!! lol)
[Galaxy Tab 7.7 Android Development] Sab3elbromba:
Which ROM would you guys recommend, here's what I need:

1. Working Phone is a must, my P6800 is my one and only phone

2. Working Wifi Tethering is preferred

3. Phablet layout is preferred

I'm currently using 2.55cm but I'm missing the wifi tethering, even with PA.apk file the adhoc wireless network created is not visible from other android phones :(

[Galaxy Tab 7.7 Android Development] Sab3elbromba:
Isn't that using a tablet UI instead of Phablet UI, meaning the notification bar is at the bottom not at the top ?

Is there a ParaAnrdoid ICS ROM available ?

Tablet UI notification will be at bottom and phablet UI notification will be on top.

For Tab 7.7 there is no paranoid ICS. Only JB
[Galaxy Tab 7.7 Android Development] Sab3elbromba:
Not too critical, just phone numbers and emails and a few pics, but why ?

So my question now is for the stock ICS ROM for the 7.7, is it using tablet notification at the bottom or phablet notification at the top ?
[Galaxy Tab 7.7 Android Development] sas_sas:

Do you think it is a good idea to flash with CROSSBREEDER or install SEEDER to run the Tablet faster ?.

I only tried Pimp My Rom before. A little but observable gain in speed in some area. Never try those you mentioned. If there is way to revert, seems no harm to try.

used seeder before, never heard from crossbreeder. but it is working fine with daniels nice cm10.1 builds. thanks for the hint to that mod!

still hopeing to see somewhen in the next momth new governors for the kernel, pretty shire that would be lead to a high lag reduction (interactive or smartassv2).

but daniel has not time for everything, therefore i'mpatient and pleased with the actual state. :)

I just finished my jobs in hand earlier this week. After a long sleep, I stuck in the manuals and codes again...:cyclops:

I'm working on the major issues bluetooth & phone now. It is a major operation on framework. After studying for sometime, I'm trying two approaches. Both requires a lot of changes in framework. Some progress to report:

1. can start the bluetooth service,

2. can scan devices

3. can pairing devices

but still need a lot of work to make it work. :eek:

4. Phone FC at start after changes in bluetooth. They are inseparably related. Hoping it will work when bluetooth is ok.

Kernel will be my next move. Waiting for the kernel codes becoming stable. New graphic driver and governors are on the list...

If anyone want to help working on the kernel, please let me know...

thanks for the pre-release, will try the bluetooth with my devices, it's the only thing I really need to use this rom as a daily engine, I can't use the jack anymore as it is partly defective.

Btw box.com already says the bandwidth is exceeded, doesn't seem to allow many downloads. On the other hand I love mega its really easy to get the link and it downloads very very fast.
[Galaxy Tab 7.7 Android Development] daniel_hk:
I don't know if it's your case. The sound file will be listed on the native sound picker after I selected it once with a 3rd party app.

I think it will only be shown when it is registered.

Good luck !
[Galaxy Tab 7.7 Android Development] 11nn93n9:
bluetooth headset is indeed not been able to connect. Maybe the default pin is incorrect since the Tab is not asking for a pin.

I also noticed that the phone profile is uncheckable. Only the audio profile can be checked or unchecked.

I make a phone call immediately after booting. After the call, the screen becomes black and I had to press the power button long time to reboot it.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah, I don't know why the service can't bind to headset(report fail in logcat). That's why I upload to pre-release to ask for second opinion...:confused:

BTW. You may have pair it before. It will ask for pin if you unpair it.

Phone is not yet fixed, please don't border to test. I think the audio driver for input is not working. Searching for the manual from ALSA & YAMAHA now.:eek:

However, I can only test a Sudio Vogue speaker phone and a Jabra BT2035 headset. Both pair automatically with no problems, but after accepting a call on both and then hanging up, there is still the old phone problem (I know your are still working on this Daniel). Also you cannot disconnect or unpair from BT until after a reboot.

don'nt know if it just for me, but since the build before this new nightly, the battelife increased a lot. so daniels work on the powersave had been working good! :)

for all, who might want to try to get a little bit more responsiness/lag reduction:for me the combi of adjusting govenor up-threshold to 75, down differential to 10 and flashing the mod crossbreeder bring some gain..... but somewhen this might not be necessary any more...

I flashed with 25.03 bt version a couple of days ago. If you kindly accept the following my comments,

What I have observed that it was very fast but consumes more battery than PA 2.55 even in sleep mode. As per my experience v 2.55 consumes noting if airplane mod. Do you agree?

İ had to return to my favorite version PA 2.55 14.01 and took sometime reorginizing file structure of int memory. No complain at all. I was informed before.

I have to tell that after using PA 2.55 very happly I did not like 4.2.2 with less options on settings. Even I did not find Tablet Ui mod and did not find the status bar to bring beside nav soft buttons at bottom of tablet screen. Was there solution for that, is it manageble to turn to tablet mod? Was it my mistake?

One other issue is DPİ change setting should be added IMO.

Thanks again to Chef Daniel for such valuable efforts..

As soon as I see that there is Tablet mod and DPİ options I will reflash it..
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah, I think it also cause Phone FC.

Something wrong in the tinyalsa driver. pcm input channel can not open. Anyone has any idea?
[Galaxy Tab 7.7 Android Development] daniel_hk:
Most of these settings are PA features...

I think power is consumed by the Phone.apk. Whenever you make/receive a call, the transmitter is not off. You have to turn off the tab to cut it off. p6810 & i815 most likely don't have this issue.

I'm working on the bluetooth of PA3. Harder than I thought. Hoping to upload it tomorrow.
