Glad to find custom ROM for 7.7 (and dev by a HK person \^o^/). Have a try but encounter some problems

P6800 HK version, Android 4.0.4, ZSLP7, Rooted

Use the stock 3e recovery to flash both CM and PA, but it stops with the following error statements...

E:failed to verify whole-file signature

E:signature verification failed

Any recommendation to me?
[Galaxy Tab 7.7 Android Development] daniel_hk:
You have to use a custom recovery, CWM or TWRP to flash custom roms.

A link to the latest CWM6.0.3.0 is on the post.

Be careful, don't wipe anything on a stock ICS kernel.

Do follow the step in post#2:)

Good luck!

I just realised why my voice input in google search and at other voice typo did not work..

Eager to see this audio issue is resolved soon..
[Galaxy Tab 7.7 Android Development] fshek:
Thanks for the instruction. Just flashed the 28 Mar pre-rel version, looking very good
[Galaxy Tab 7.7 Android Development] daniel_hk:
The external sd not mount on pa3.15b1. Fixing it now...

Don't use the phone yet. If you try it, turn the tab off. The transmitter may not shut down properly and will drain the battery.
[Galaxy Tab 7.7 Android Development] fshek:
Tried the phone before reading your post and the device's gone crazy... Wahahahaha

Looking forward to having the phone, SD mount and other tiny bugs fixed... 加油... 努力!!!!

The opensource tiyalsa audio input is not working. When you open it once, the audio in/out will be stop. The audio output will work again after you reset.

Good luck!
[Galaxy Tab 7.7 Android Development] daniel_hk:
It's ok. It was not shown in Media Storage first. After I select it once with ES, it shows in the Media Storage.

1. Settings > Sound > Default notification sound

2. ES (just once) location the file

3. Settings > Sound > Default notification sound

4. Media Storage

I include the screen shots.
[Galaxy Tab 7.7 Android Development] wintermute000:
Hate to report this dAniel but I think your latest 26/3 CM10.1 build has some of the same 'lag' issue as your PA build. Its lagging more than the 3/3 build esp. when changing applications or starting them, screen rotation, etc.
[Galaxy Tab 7.7 Android Development] daniel_hk:
I think the kernel need to update. Working on the new video driver now...
[Galaxy Tab 7.7 Android Development] himadri:
very interesting

Very nice work. As soon as you post a stable build I shall give it a try and give feedback. Thanks for developing for our beloved tablet.:highfive:

Re: [ROM][p6800/p6810/i815] (1/4/2013 CM10.1) Jellybean Custom ROMs & CWM

Skype voice and video calling still not working....
[Galaxy Tab 7.7 Android Development] daniel_hk:
Skype has issue in JB4.2.x . You can't login microsoft account with JB4.2.x

I don't know which version of Skype you test. I've tested both voice and video call with my phone a few times before posting. It works.

My Skype version is 3.1.0.6458

Make sure you download the 2013/4/1 ROM.

Edit:

Sorry, the kernel changes not covering p6810 & i815, redo it and will upload again asap.

Thanks for you report!!

Hi, just did a quick check of 1/4/2013 and I can confirm hat Google voice search and Skype (voice and video) are working without any issues. Many thanks and regards, Trashx
[Galaxy Tab 7.7 Android Development] lomniom:
Got my tab back from repair, thank you for all your effort!
[Galaxy Tab 7.7 Android Development] cymagnus:
Tested out the 1/4/2013 release for P6800. Stock browser is not working correctly for me.

Got FC out when I navigate Google.com, browser will also FC when I do a double tap (to auto fit web page).

Not sure you buus got this problem.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah, something like that not FC just quit. No error in log??:confused:

I seldom use this browser so didn't test it. Chrome & Firefox look ok.

Only related change is the graphic driver. Will try it on PA to see if the new graphic driver cause it.

Thanks for you report.

AW: [ROM][p6800/p6810/i815] (1/4/2013 CM10.1) Jellybean Custom ROMs & CWM

I can confirm that but I never use the default browser. I prefer dolphin beta on my SGT7.7

regards, TrashX
[Galaxy Tab 7.7 Android Development] jchenny:
Thanks for checking this out, and when do you think it will be updated? since Skype is the most important function for me on my SGT 7.7...
[Galaxy Tab 7.7 Android Development] daniel_hk:
Just test the new build of PA with the same kernel. Stock browser is ok. I think the recent changes in CM's browser cause it. It will most likely be fixed in the next update.

Hi friends,

Is this ROM working well with Tab 7.7 now? please let me know which version is good? Thank you very much.

Kind regards!
[Galaxy Tab 7.7 Android Development] daniel_hk:
You better wait for a while. Just fixed the phone issue and will upload to pre-release soon.
[Galaxy Tab 7.7 Android Development] johnnobts:
very excited man, can't wait to have working phone with your rom. hoping i can get the internal/external sd swap script to play nice with it this time as well. keep up the good work. btw, read that the 7.7 jelly bean update is still coming but has been delayed to may/june (sigh).... Am being tempted by the Note 8.0 and her wacom stylus to go with my Note 10.1. Still, there is just not beating AMOLED.

For the skype conference call, Is there anyway to switch the speaker from the ear speaker at the top of the screen to the loud speaker at the bottomof the screen?
[Galaxy Tab 7.7 Android Development] daniel_hk:
Don't know p6810 but my p6800 will use the bottom speak. Ringing is at the top speaker.

I just use Echo/testing to test it.

May be it is the patch in AudioFlinger when I fixed the phone in p6800.

l'll upload the 3/4/2013 build for p6810 & i815 when they are ready.
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
Wooow, you actually got the phone working without the tablet hanging ans freezing, that's amazing.

Thanks, I will test it next Friday.

[Galaxy Tab 7.7 Android Development] GNUDroid:
Hi Daniel!

If I'm right, it could be that a dream comes true: I was reading in the i9100 corner: If not the developer Kroz did this (normally he uses stock CM kernel) it seems that newest CM kernel sources are containing the very very nice CPU govenor "pegasuq"!!!! This should remove all up-scaling lag we still sometimes have on the 7.7! :D

to cite from the the recent finding:

...

android_kernel_samsung_smdk4210

Merge "i777, i9100, n7000: enable pegasusq gov" into cm-10.1

Merge "mali: 3-step gpu DVFS control" into cm-10.1

Merge "block: add row io scheduler" into cm-10.1...

see http://xdaforums.com/showthread.php?t=1806401&page=772

can you confirm, the CM sources now contain a more modern scheduler?

Best regards from europe,

GNUDroid
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah, I notice that. Seems doable in our tab. I'll try it after the relesaing the new PA.

Keep reminding me if something like that coming up! Thnaks.:good:
[Galaxy Tab 7.7 Android Development] pillarama:
Hi Daniel, I've been following your progress here for a while now and I'm seriously impressed! Well done man! :highfive: I really thought bluedroid was going to be the end of the game for our Tabs...

I've been testing every one of your builds as soon as I can get my hands on them and there is obvious progress with each one.which is seriously exciting!

I've compiled a report of my tests today from your 2013-04-03 build using:

- a bluetooth headset (a knock-off Nokia BH-503) (HFP / A2DP / AVRCP)

- a Bury CC9060 car hands free (HFP / A2DP / AVRCP / PBAP / BMAP)

- and some other non-audio related peripherals (Apple Bluetooth Keyboard / Apple Magic Mouse / SGSII running CM10.1 nightly).

Let me know if you would like me to post the results for you.

Thanks once again for all of your hard work!!
[Galaxy Tab 7.7 Android Development] FernandoMiguel:
I flashed the latest test build on P6800 this morning.

the browser FC is fixed.

sound recording is working as it was in the previous build.

Phone app does startup, but every attempted i made to dial resulted in error 408 timeout

Thank you so much for your hard work.

I'll make a donation when i come back from my trip!!
[Galaxy Tab 7.7 Android Development] daniel_hk:
Sure! every bit of information helps.

As I mentioned before, it's a team work now.:)
[Galaxy Tab 7.7 Android Development] daniel_hk:
Don't know why you can't make phone call but 408 seems related to the sim card. Make sure you can connect to data first. See if you can get the setting like call waiting in the setup of phone. If everything is ok, I think you can make calls.

Good luck ！
[Galaxy Tab 7.7 Android Development] jacky169:
Thanks Daniel for SUPPORT OF 7.7 I flash it today its mark faster than Samsung 404 HK ROM.

Thanks again

---------- Post added at 02:08 PM ---------- Previous post was at 01:29 PM ----------

Hi daniel , one more question why not much custom kernel for 7.7 ? If one kernel can be contain deep idel and a bit oc (1.6GHz) preferred .(or any kernel support that CM10.1 rom)

Thanks
[Galaxy Tab 7.7 Android Development] daniel_hk:
What we are having now is the only CM kernel which is modified from the stock source. The main source is still from samsung's kernel source. The CM team pick drivers here and there from other devices which have the same chipset for some part. Most of the changes in our kernel are copied from SII kernels. People working hard on it should take the credits.:good:

My next step is the kernel. Gathering info. now. Will start after fixing the bluetooth headset.
[Galaxy Tab 7.7 Android Development] currway:
Daniel, great to see the new breakthrough for phone app !

Btw , do you mind clarifying if these limitations are still true for your 3 Apr 2013 build ?

- wifi: won't connect to hidden ssids

- wifi: will only connect to 5GHz networks when immediately adjacent to the router

- wifi: built-in wifi-tethering doesn't work
[Galaxy Tab 7.7 Android Development] daniel_hk:
The latest version is 04APR2013. uploading to pre-release now.

Yeah, those issues are still there! I haven't touch that part yet. Don't know how for the time being...I don't have a 5G router too:o but I'll take a look when dealing with the kernel later.
[Galaxy Tab 7.7 Android Development] jacky169:
Hi daniel ,

if I upgrade from 1/4 to your lastest verion 4/4 CM 10.1 , is needed to flash gaapps again ?

thanks again and support

Cheers!!!
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah, you need to flash gapps again.
[Galaxy Tab 7.7 Android Development] daniel_hk:
It is a detail and professional review! :good:

Will following it to see if anything can be done.

Thanks
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
Downloading and going to use it as a daily driver from now on, but please is the phone functionality is fully working?

i use this tab as a phone 24 hours :)

Thanks Daniel for your great work, I really miss CM10.1 very much, really thanks :)
[Galaxy Tab 7.7 Android Development] daniel_hk:
It's OK if you don't use bluetooth headset. You better try it yourself.

BTW, PA3 has similar issue but phone also work.

Good luck !
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
yes, but the earpiece is fine, right?

i can hold the tab to my ears and make phone calls?
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah，both earpiece and speaker handsfree are ok.
[Galaxy Tab 7.7 Android Development] sbkoh-xda:
I can connect to 5GHz wifi networks without needing to be immediately adjacent to the router. On 20130325 build. Daniel can remove this item from the list. :victory:
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
After couple hours of using, it's amazing, I stopped cm10.1 from a while because the Vsync and phone problems were very annoying,

but both problems seems to be solved on this rom.

I will start to use as a daily driver, and will write a review after couple of days.

anyway there's a minor complain about the default screen rotation should be portrait.

i read the alan orth (aorth) fixed that for tab 7 plus which is the same as our in the common smdk4210 .

https://plus.google.com/101880444013156960674/posts/4PRoqfaKLqx

if you can merge this fix, it will be perfect :)

I will try to contact him and get you a batch or something.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Thanks for your report!

Anyone has issue in 5G?

I'll remove it tomorrow if no one report fail.:fingers-crossed:
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
The phone app force to go to landscape mode, i think it might be related to the idea the tab default orientation is landscape.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Already reported by others. I repeat once more. That is the behavior of the Phone app. AOSP & CM share the similar codes. Seems portriat is not handled inside. I'll look into it again to verify.
[Galaxy Tab 7.7 Android Development] cymagnus:

[Galaxy Tab 7.7 Android Development] Mike02z:
Hi have been using this ROM since I purchased my i815 about a month ago. My only issue is BT. I can connect to BT receivers but cannot stream music or Navigation. This is a major issue for me as I built my i815 into one of my cars to use to stream music and Nav to the HU. Until the last release, it would not even see the HU. Now it sees it, will pair but will not send output via BT. it even says it is outputting to BT.

I finally had to go back to stock 4.0.4 and the BT is working as it should. As soon as you get this working Daniel, I'll be back. Thanks again for keeping dev for the 7.7 going!
[Galaxy Tab 7.7 Android Development] lomniom:
I think i left it too long it finished the battery. Now it is not even charging anymore.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Don't worry, just leave it charging for a few hours. It will most likely be coming back.:fingers-crossed:
[Galaxy Tab 7.7 Android Development] lomniom:
Yup, that was what I did. Very glad it came back alive. Thank you for developing for us! Your ROM is nearing perfectness.
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
Sadly The Vsync is broken, I can bear the butter smooth is broken, but Vsync cauzes tearing and glitches all the time.

I noticed it when scrolling in Facebook app, notification center menu, settings menu ....etc

also if you can notice vertical lines when you pull down the notification and dimming effect is taking place.

If you can fix it, it will be nice.

Is it broken for the rest of Exynos devices?
[Galaxy Tab 7.7 Android Development] daniel_hk:
The video driver we are using is from Samsung Note8 almost identical to N7000 from samsung's opensource.

I don't know how to change it...You better switch back to stock rom.
[Galaxy Tab 7.7 Android Development] lomniom:
Daniel, do you succeed in your Bluetooth issues?
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
No switch back until Samsung release jb rom for the tab +the rom is amazing in every way.

What i'm complaining about is minor bugs.

So let me understand it, you using the driver as a binary blob, but you can't access the code inside it to see the interfaces?
[Galaxy Tab 7.7 Android Development] daniel_hk:
No, it is the source from Samsung but I don't know how... I think I need a lot of reading for the chipset specification before I can do anything. It is inside the kernel. Almost 20M of texts! I don't think I can do a better job than the experient Samsung engineer.

The new source also has improvements so no way to switch back to the old one.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Haven't find where goes wrong yet so I proceed to the kernel to clear my mine for a few days. I need to borrow some other bluetooth headsets to test and make sure what goes wrong.

I'll continue after the kernel...
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
mmm, 20M of code!! That's a lot !!

alright, thanks anyway this so far better than CM10 benchmarks, it scored almost the same as stock roms which is really amazing.

Thanks for your work and for CM too.
[Galaxy Tab 7.7 Android Development] currway:
Daniel, any chances of referencing subforums of other devices that shares the same exynos A9 SoC with Mali? Most probably those devices would have got it butter smooth.
[Galaxy Tab 7.7 Android Development] Gilbot:
i815 most recent build has aosp browser crash, how can I get this fixed? I tried uninstalling and reinstalling browser to no avail :(
[Galaxy Tab 7.7 Android Development] daniel_hk:
This Mali driver from other device. Which is already the latest version of our 4210 board from the latest JB 4.1.2 source from Samsung.
[Galaxy Tab 7.7 Android Development] daniel_hk:
The new CM source will fix it. I want to finish the kernel before posting new version. In a few days...:cyclops:
[Galaxy Tab 7.7 Android Development] grazy:
Thanks Daniel for bring us overclocking feature. Testing the latest pre-release built now. Will report if got any issue. Cheers.
[Galaxy Tab 7.7 Android Development] currway:
Daniel, any chance for getting in hotplug, interactivex governors as well?
[Galaxy Tab 7.7 Android Development] daniel_hk:
If there is one in other kernel, would not be hard to include. Do you have any link?
[Galaxy Tab 7.7 Android Development] jacky169:
THanks for supporting the OC kernel update .

Thanks.
[Galaxy Tab 7.7 Android Development] rebornsoul89:
Hi guys, my device always lags badly a few days after installing the cm10.1 rom. The first few days are perfect, but after that the device lags badly, and everything force closes. I have to wipe device and cache and dalvic then reflash the rom to remove the lag. Can anyone help me on this?

I have tried multiple builds of the rom but the result is the same. Device lags badly after a few days or when i dont use it for long periods(one day). Rebooting doesnt solve the problem too, only reflashing will solve the problem.
[Galaxy Tab 7.7 Android Development] ZhenMing:
Hi Daniel,

Any where to just pack the OC/UV kernel only for CM10.1? so that this can be shared among PA3.15 and CM10.1.

Thanks.
[Galaxy Tab 7.7 Android Development] GNUDroid:
first 20 minutes impression

Hurray! The playground is opened! - Thank you so much Daniel!

I didn’t had really time to test and validate my findings, because I was on the rush to office.

Played around with the new governors and overclocking: Found some things which I (or somebody else should validate). I have the impression, that there MIGHT be some bugs. – But as I said I’m not sure at the moment. I’ll test by time.

1)	Tested pegasusq governor:

Everything seems to be right. Scales over whole MHz range. From GUI experience, it seems not to bring the boost as expected. Also lowered the values for up-threshold and lowered sampling rates (app trickster mod). At my launcher, I still experiences some lags in animations.

2)	Tested also the interactive:

Also here I lowered up threshold to 75% and slightly decreased sampling rates. HERE: System tuner (maybe it is just a failure of this app) shows, that CPU up-scaling seems to stick at 500 MHz. I tried to set 16000 MHz and 14000 MHz under performance control and also with the app trickster mod. Both the same.

GUI experience was very laggy, therefore values of system tuner MIGHT be right.

Had one crash at switching from pegasusq to interactive (had load on the CPU whilst doing this)

>> ALL my findings are preliminary, had just 20 minutes for testing. But if somebody wants to play: please also test and give Daniel input. To summarize: Pure Android GUI and launcher speed: quite similar to my tuned last Cm10.1 build from Daniel (with ondemand tuned and crossbreeder) , but 3d intensive google earth seems to be faster with the new build.

Nevertheless: Daniel did the breakthrough for us!!! Now we definitely will have the chance to get a tab which knocks out many other tabs by fluidness. I’m pretty sure, now Daniel is much more experienced with android, kernel and the whole system internals.

So much effort for us, DANIEL, THANK YOU SOOOOO MUCH!

:) <<

3)	Two things want to mention:

Because I had good experiences with the crossbreeder mod here from xda on the older roms, I also had this installed on daniel’s new build. Maybe it is too much and could affect daniel’s new kernel. … I will test without that mod by time…

And one additional thing: Because with the new interactive and also pegasusq (both can be configured a little bit more aggressive by everyone), we can be shure, that CPU-scaling should be fast enough. But: I did not investigate the frequencies and scaling behavior of the GPU. I’ll test by time, if the “mali status” app, I use on my s2 can bring us some information about min/max frequencies and the scaling speed…. Maybe someone can give me a hint, if he knows other apps, which can monitor somehow the GPU-frequencies.

4)	Apps I used:

- Crossbreeder mod (xda; flash through recovery increases seeder entropy; brought some response improvements on older kernels with the ondemand)

- System tuner (watch CPU frequencies, tune)

- Trickster mod (tune govenor parameters, frequencies)

- build-in android Performance control
