You will have to redo the widget again, for sure.

Other cm9 or 4.1.1 buidl will be similar to the one you have now.

If possible, ask someone to help you redo the widget for you.

:)
[Galaxy Tab 7.7 Android Development] carlo67:
lol 50 widgets of them lol and I have the Rain Alarm Pro app , I have LOTS of different settings in Rain Alarm Pro in widgets [I have about 30 widgets ]

no way lol redo again
[Galaxy Tab 7.7 Android Development] daniel_hk:
I do't know if your Tab is software brick. There is some JTAB devices (RIFF & OGT) can reflash the bootloader to Phones. I'm looking for these kind of service now. Hoping you may find such service locally. Will update you later.
[Galaxy Tab 7.7 Android Development] Bthor:
I saw exactly the same symptoms on the tab of a friend. Turned out it had crashed and drained the battery to 3.1V The threshold where the normal (external) psu could charge it is something like 3.7V. A friend of mine hooked up the battery directly to a bench powersupply and force charged to it to just over 3.7V. This brought it back to life. It has been working fine since.

Easy enough to check. Open it up and check the battery voltage. (I don't know if you can measure the batt voltage externaly)
[Galaxy Tab 7.7 Android Development] daniel_hk:
Thanks man!

My battery is ok. Just before reboot, It was fully charged. Even if the battery issue, We still can go to download mode with charger connected.

This time my bootloader is corrupted for sure.

An engineer from the service center wisper to my friend over the phone that the motherboard is ok but their company policy is changing and won't reflash the bootloader.

The board cost over US$200+cheching charges with only one month warranty. And they will keep my "good" motherboard (to rob others I suppose)! That mean they charge me with the board doesn't need to replace and keep mine as spare part! It piss me off!

If I have a JTAB device , I can dump the content and reflash the bootloader. I'm looking for these kind of services. I won't pay Samsung a cent any more for sure!:mad:
[Galaxy Tab 7.7 Android Development] sbalu:
It is outrageous!
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
Entropy512 spoke about mobiletechvideos (or any other JTAG recovery house), and he said that they are able to recover with JTAG.

can't they reflash bootloader if you sent you device to them?
[Galaxy Tab 7.7 Android Development] daniel_hk:
I hink so. These kind of services are we looking for.

I found one workshop here (85km from my place). They said they have a RIFF JTAG which can recover the bootloader. I'll bring the Tab to their workshop early next week.

Thanks man!
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah!

Samsung just continuously release new model and left the old model behind. This way is to force you to keep on buying new models.

I just download the soucre of the JB n7000. Only few changes are there. Don't know why it take so long! :(
[Galaxy Tab 7.7 Android Development] carlo67:

Overclocking Question.

New to P6800.

Overclocking Question.

What kernel is best compatible with Daniel_HK's 2.55 rom?

Also, how do I use this ROM is portrait mode always?
[Galaxy Tab 7.7 Android Development] deani77:
Re: [ROM][p6800/p6810/i815] Jellybean Custom ROMs (17/2/2013 4.2.2r1 update))

Since it was based on CM10 maybe you can try kernel from other CM10 ROM.
[Galaxy Tab 7.7 Android Development] GNUDroid:
I would not follow that advice. Kernels MUST suit to the actual hardware. Do not use a different kernel from another device. Here we do not have a separate list of kernels like on many mobile phones, which you can select and flash to a rom build. - too less developers here. The kernels are bundled to the specific ROMs. But I concerning the ROM for a tab 7.7: I recommend the latest cm.10.1 build from daniel _HK it is much faster than the PA 3 beta builds. - Hopefully Daniel will have enough time to continue both.
[Galaxy Tab 7.7 Android Development] sbalu:
... and a tab.
[Galaxy Tab 7.7 Android Development] deani77:
Re: [ROM][p6800/p6810/i815] Jellybean Custom ROMs (17/2/2013 4.2.2r1 update))

I mean kernel from locerra/aorth CM10, not from other device. I think everybody knows that when deal with custom ROM
[Galaxy Tab 7.7 Android Development] carlo67:
did you got your tab back yet?
[Galaxy Tab 7.7 Android Development] daniel_hk:
Re: [ROM][p6800/p6810/i815] Jellybean Custom ROMs (17/2/2013 4.2.2r1 update))

Yes, I got it back but not fix yet..
[Galaxy Tab 7.7 Android Development] carlo67:
what wrong with it?
[Galaxy Tab 7.7 Android Development] daniel_hk:
The bootloader corrupted. Can't turn on. Already said it many time, don't want to repeat...:(

I went to a workshop this morning but I don't think they know how to fix it. I don't want to left it to them. I took a freelance job. Need a few days to finish. I will try another workshop this week end.

Please be patient, at least you got a working tab to play with, just relax and enjoy it for the time being.

Even though I have a tab, I can only try to see if anything can be restored from /data to get the widgets back. No garrentee it will work for all/any widget.

As I said before, if we are in the same city, I can help you redo all the widgets. Helping a disable is what everyone should do.

I seldom break a promise but I got much bigger issue to deal with now...:(
[Galaxy Tab 7.7 Android Development] carlo67:
it is cool, i just asking.

I have not experience with bootloader. can you go to download mode?

actually I have 2 tab 7 7 tabs

ok thanks
[Galaxy Tab 7.7 Android Development] daniel_hk:
No download mode, not even the battery icons when charing...:(

Don't worry, I believe there is always a way for anything...;)
[Galaxy Tab 7.7 Android Development] FernandoMiguel:
wiped and flashed PA beta3 but it was missing several features from CM10.1 (and the wonderful cronus widget), so wiped caches and flashed your CM10.1 on top.

everything working wonderfully on both ROMs.

Thank you for your work!!
[Galaxy Tab 7.7 Android Development] Gilbot:
Hello daniel, any plans to drop any cm 10.1 builds that include the recent mali gpu fixes? I'd love to try em out.

Alternatively, I am setting up my macbook to build from source for my i815 following this guide: http://xdaforums.com/showthread.php?t=2087318. I am nearly done syncing the repo. At this point I assume i need to edit/create the local mainfest that pertains to the i815. Most of these command lines are alien to me, but I want to learn how to build for myself to test out stuff.

Any help is appreciated.
[Galaxy Tab 7.7 Android Development] carlo67:
I have a question

I got 2 p6800 tablets. But one of tablet is running slow. I got same cm9 on both of tablets. I don't know why it is slow

and I get lot of WAIT and FORCE CLOSES and slow to load apps
[Galaxy Tab 7.7 Android Development] daniel_hk:
I have tried it. Stuggling for a while and change a few things before it can be compiled. The kernel become dirty (shown in the info) and fail to boot.

I think you better wait for a few days before all the kernel updates become stable. I'll try again after finishing my jobs in hand..

I haven't touch Mac OS for 2 years... Just take a look at the guide for mac-os, seems quite similar to linux.

To build CM10.1 for i815, you may need the following projects:

<project name="TheMuppets/proprietary_vendor_samsung" path="vendor/samsung" remote="github" revision="cm-10.1"/>

<project name="ohanar/android_device_samsung_i815" path="device/samsung/i815" remote="github" revision="cm-10.1"/>

<project name="ohanar/android_device_samsung_smdk4210-tab" path="device/samsung/smdk4210-tab" remote="github" revision="cm-10.1"/>

You may also use alanorth to replace ohanar. Both are good to go.

The reset just follow that guild:

P.S.

after "lunch or brunch" the following projects will be added automatically to ./repo/local_manifest.xml or ./repo/local_manifest/roomservice.xml in your working directory:

android_kernel_samsung_smdk4210

android_hardware_samsung

android_hardware_atheros_wlan

Goodluck !
[Galaxy Tab 7.7 Android Development] SolusCado:
I realize this probably isn't the appropriate location to post this, but it seems like the GTab 7.7 forums have become a bit of a mess, and I cannot find what I need...

Anyway, while I love this ROM, the lack of Bluetooth is a bit of a deal-breaker for me. I realize that it is because Bluetooth doesn't work in CM10.1, and it has been this way for a while - so I'm doubting that will change in the near future. (Or will it? Does anyone here know something I don't?) Assuming Bluetooth support ISN'T on the horizon, can someone recommend a ROM for the i815 (Verizon Wireless version) that does support Bluetooth, and is running a recent build of Android? (All I can find are stock ROMs...)

it is working great for me. :)
[Galaxy Tab 7.7 Android Development] daniel_hk:
Did you try pa2.55? It's 4.1.2 and bluetooth is working.

I have never tested it in an i815. Really need someone to report any issue.

Goodluck!
[Galaxy Tab 7.7 Android Development] SolusCado:
I'm pretty sure that's what I was using before, and bluetooth didn't work on it either - but I'm downloading now to double-check.

Actually, scratch that - I cannot find a download link for 2.55. Do you have one handy?
[Galaxy Tab 7.7 Android Development] daniel_hk:
The latest version is Jan14. Bluetooth works fine on P6800 and P6810. I assume that it work for i815 too.

Wipe data/Factory reset is required. Please let me know the result.

[Galaxy Tab 7.7 Android Development] daniel_hk:
If you have seen post #145 on my pa3.0 thread, you can have a better understanding of my situation.

Up to this moment, baidu is the only place I can upload faster and can share the whole folder. If anyone has other alternative, I would love to try.

Which model you have? If you really can't download it, I might try uploading that particular file to other host....:eek:

Bug on P6800 CM10.1-20130302:

Brightness settings under `quick settings bar` (status bar) not responding.

To adjust brightness, have to go to the main `Settings`. Or via `Power Widget`
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah, confirmed by my friend. But I never touch that part and PA3.1 is ok. Seems cause by the recent update from CM...

Thanks for your report! ;)

6810 on CM10.1-20130302: Thank you daniel for the latest build!

1_No bugs at the moment:

The build is running fine for me on 6810! Was not able to find a obvious bug at the moment. Did not tired the brightness toggle, but nevertheless even the slider/swipe in the notification bar works; I use this method for brightness control.

2_Performance:

The build is fast. Compared to last CM10.1 build, I don't feel much difference. Also PA got fast since your 3.1 build (3.0 betas had lags). I carefully took a look at the CPU loads whilst doing things. Nevertheless I try build.prop tweaks, adjusting the ondemand governor settings (sampling rate, up-threshold) or using the quite good seeder-app: No chance to remove some lags in the very beginning of all scrolling/animation.

Did anybody respond to my request in the S2 forum, to maybe help you how to apply the available kernel governor patches to our devices? Something faster-scaling than the neat ondemand would boost the device for sure.

Thanks again for your great effort!
[Galaxy Tab 7.7 Android Development] sas_sas:
Ths for all Daniel_hk..

After flashing the below if we need to return to PA v2.55 14.01.2013 is it possible and easy ?

Sorry, I could not find the download link of built for P6800 below,

"5/3/2013:

Working on the kernel for the whole weekend. Hoping to identify the problem of bluetooth and Telephony. Stuck in the latest kernel source! It fail to boot and required a lot of changes. With my friend's tab in hand, I finally managered to correct all the errors and build it out but waste the whole weekend! The lastest cm10.1 builds with the new kernel and other updates from CM is uploaded to the pre-release area. Please test and report."

Or is not it CyanogenMod 10.1 (4.2.2r1) ?

or is not it for P6800 ?
[Galaxy Tab 7.7 Android Development] daniel_hk:
If you are from 4.1.x, move to 4.2.x is straght forward. However, you need a little bit more effort to switch back to 4.1.x from 4.2.x. The content of the sdcard is moved from /sdcard to /sdcard/0. You need you manually move the contents back to /sdcard.

My advice is making a backup in recovery first. After restoring the 4.1.x system and reboot, use a root browser to move everything (there might be some hidden folders) from /sdcard/0 to /sdcard, merging folders and overwriting files if required. You may delete the empty /sdcard/0 folder afterward. Then you'll be back to your original 4.1.x. It take some time but not difficult.

The latest build is in the pre-release area for testing. There are 2 sites or pre-releases and 6 files are inside each site now.

Goodluck !

I come from 2.53, do I simply flash 2.55 under cwm recovery and then wipe data/cache?
[Galaxy Tab 7.7 Android Development] daniel_hk:
If you're from pa2.53, you probably don't required to wipe data.

If and only if you encounter hardware issuess, may redo wipe data later.

Just flash over the 2.53 with 2.55 and gapps will do.

Aroma version is the better choice. You don't need to download and flash gapps seperately with the Aroma version.

glad to see that your tab back to normal... need to send mine for repairs... change of battery actually...
[Galaxy Tab 7.7 Android Development] 11nn93n9:
Nice to know your Tab is back. How do you JTAG it? Any special equipment?
[Galaxy Tab 7.7 Android Development] daniel_hk:
Yeah. There is a special board connect between the tab and a PC. After the back cover is removed, There is metal shield covering the cpu board. Below the shield are two connectors. The workshop has the right adapter to plug in. (there are many different type of adapters for different phones.)

The battery is disconnected first. When a usb cable is plug to the tab, Tab is power on automatically. The PC act like a console to the tab's cpu. After that we can upload/download data to a specific address.

Not a difficult task but require the right equipment. The owner said, a set of these type of equipment and adapters cost about US$250. He charge me US$25 which is very reasonable. The checking charge for Samsung is already US$20! Just pressing the buttons for a while and said the mainboard need to be replaced!:mad:
[Galaxy Tab 7.7 Android Development] sbalu:

[Galaxy Tab 7.7 Android Development] bassem.mohsen:
if we flashed Galaxy Note 1 Rom on our tab, why it will not boot up or work?

theoretically it should work, i mean the two devices are the same chip set and target processor is the same, same Partitions.

I want a scientific reply if anybody knows, why it will not boot up practically ?
[Galaxy Tab 7.7 Android Development] daniel_hk:
I try to list it in points and only list a few major issues:'

1. The partition table is different:

n7000: kernel,reovery,system,data in partition 6,7,10,11

p6800: kernel,reovery,system,data in partition 5,6,9,10

If directly flash the stock rom with Odin, a new PIT file must be included to re-partition the p6800 in order to pass the flash! Everything will be gone and most likely not work!

For custom stock roms, we may change the installer-script and repack the kernel with different mount points. Needs a lots of sweaty works...again most likely not work!

2. modem is different.

May use the original modem from p6800.

As a result, no way to flash n7000 rom directly without any modification.

3. Hardware differences: wifi and bluetooth.

The stock roms include those drivers as modules in kernel.

Stock kernel also has different graphic buffer sizes. Don't know if it also work for p6800.

The new 3.xp1 Mali driver doesn't work on p6800. Don't know why yet.

We may replace the drivers. Either in kernel modules or push the driver out to /system/lib.

As a result, the stock n7000 kernel is surely not boot if we don't rebuild it.

Even if we use the stock ICS or CM10 kernel dircetly. It will probably boot and stuck at bootanimation.

Hope you know what I mean.

Coincidently, I'm studying the possibility of building the 'stock' JB rom for p6800 with the n7000 source now...:cyclops:
[Galaxy Tab 7.7 Android Development] bassem.mohsen:
1. I think this the hardest problem, if you can solve it, i think we can make initial release with Wifi/BT and modem doesn't work, and then think in work around for the rest.

2. easy for you as i think, or even you can remove the modem section from the img and leave the modem partition as it is.

3. The WiFI/ BT driver exists in this path "Kernel\drivers\net\wireless\ath\ath6kl" in the JB kernel source code.

if you can modify the code to use this driver instead of the GNote I driver, then you will be good to go.

if it's that easy, why Samsung is delaying us like this !!!
