well I got both the device.... (Ipad was a gift...just to specify! lol)

Ipad is going for sale on ebay...

enough said!

for the everyday user Ipad is the way to go...

but if you got some knowledge, well galaxy tab is simply 100 years ahead of every apple stuff!

I remember apple publicity where they advertize the videocall as one of the best feature of the iphone4 and many apple customers think that videocall is an apple innovation when it's there from ages.apple got excellent marketing...but that's all , they can advertize a stone just as a revolution...but again they can hit avarage users...I see no power users/experts going to apple stuff nowaday.

some folks choose apple notebooks just cause they can switch between windows/osx thanks to intel hardware...they stopped to use even their cpu in their apple pc...cause the competition (AMD,INTEL) just was/is years ahead

ipad hardware was just ridiculous when it was launched ....it born obsolete...now is COMPLETELY obsolete...256mb of ram on a custom hummingbird 1ghz cpu...no front camera/****ty rear one...lack of thousand of features (real multitasking lack, most important!) that even a 100$ cell nowaday got.

it's very simple to boost performance on a mobile tab/phone when you don't need to support multitasking...that's why apple chose not to implement multitasking natively...
[Galaxy Tab  Android Development] Super-S:
what? ...IPAD with only 256MB Ram? Its not 512MB?

:cool: not good....
[Galaxy Tab  Android Development] triplex76:
no no, it got two blocks of 128mb each one embeeded in cpu...

http://www.zdnet.com/blog/hardware/ipads-a4-processor-uncovered/7928

just to laugh! lol

"The primary focus of this design was minimizing power consumption and COST rather then developing a revolutionary new CPU"

so Samsung custom cpu and obsolete SGX535!

Just thought **** happens and went for the full version + Pit file... Still stuck at the Samsung logo and looping there :(
[Galaxy Tab  Android Development] triplex76:
flash the dbdata and you should be good to go!

or just flash the full WITHOUT pit ... it worked for me!

[Galaxy Tab  Android Development] Alcibiade:
Flashing without Pit worked for me

Thanks :)
[Galaxy Tab  Android Development] triplex76:
yes, I know...

flashing without pit allow to overwrite just everything,

using pit instead just overwrite only the parts with a different md5.

so for a real full flash No pit is the way to go.
[Galaxy Tab  Android Development] zaoltryence:
Do anyone of you observe that when you are charging your tab the battery indicator is moving but when you check the battery percentage it doesnt move until its fully charge then when you take it out on the charger it goes back to previous so you need to reboot for it to show real percentage, its been like this since i updated my tab to v2 is there any explanation to this, any fixes aside from calibration, tried it but never worked

i have two issues with still remaining(not exactly huge problems, but irritating)..

i still have the voicemail icon even though i obviously cant get voicemails(dont have a sim) - did anyone have a fix for this? i tried clearing the dialer cache, it goes off for a min and then comes back once again. i see that another ROM chef said he fixed it and I just wanted to find out if any ROTO rom users were able to get it working... would be awesome if i could fix this

english dictionary force closes - i cannot un-install it in manage apps section.. the problem being - i installed JMI over an upgrade over JMG so i still have that english dictionary lying around...

i dont have titanium backup so cant really flash JMI all over again, which will problem 2, but not problem 1(tried it already)...

can anyone pls help me out (i am not a regular flasher, so usually if something is fast/stable i will stick with it until the next big thing as i dont have titanium backup to restore back to normal easily, waiting a little before i buy it)

Roto, your ROM flies with the 1.4 Ghz patch :P
[Galaxy Tab  Android Development] p_hsieh:
Hi Alcibiade,

A couple of questions:

1) On the 1.4ghz OC/UV thread, triplex76 stated in #279 that

JK=works great! (data will be 100% there after flashing!)

JM=different issues "use at your own risk"! (data wipe EVER OCCURS! BACKUP NEEDED!)

Since we're running a JMI here, do you have the freezing problem?

2) Are you experiencing any power improvement or no at all?

Thanks!

Peter
[Galaxy Tab  Android Development] bdl1969:
The data wipe depends on what commands are in the CSC cache.rfs command file. For JMI the commands are:

--update_package=CACHE:recovery/sec_csc.zip

--wipe_cache

--wipe_data

--emmc_check

Which mean that data will be wiped! If you open up the cache.rfs and look in the command file with a text editor you can check for yourself before flashing. Personally I prefer using the CSC from JMG with the JMI PDA as there isn't a --wipe_data command in the JMG CSC.
[Galaxy Tab  Android Development] thegrau:
I've installed this ROM and it works really well.

I do have a strange issue, though : Maps keep on crashing if I change the pixel density. Is it related to the ROM itself, considering I never had this problem with other ROMs ? Is anyone experiencing the same issue ?

[Galaxy Tab  Android Development] raaleck:
Tabing, at first how do you uninstall it? And what is the name of the app you uninstall?

You need to uninstall it via Titanium App and the app you will remove is " English Dictionary"

If you removed another one, try to change to the native keyboard if you are using other wich is Samsung Keyboard. Try to download Titanium and make a backup of the apps. And you reflash the ROM to fix the problem.

This is just in case you removed other dictionary app. When you reflash it go to markwt and download titanium to remove English Dictionary App.

I hope this help, If isnt your case I hope rhis help someone else with this issue.
[Galaxy Tab  Android Development] Jade Eyed Wolf:
To upgrade, or not to upgrade...

As I've mentioned earlier in this thread (at least I think it was this thread :P), I am currently running JMEv4 on an AT&T Tab (carrier unlocked and GPS fixed). Everything, and I do mean EVERYTHING, works exactly as I would expect. Swype is full screen in landscape, as it should be, for example. My only little niggle with the whole device is performance related. The whole experience isn't quite as snappy or as responsive as I would like it to be overall.

So here's the question:

I know JMIv2 fixes a lot of the performance issues, but at what cost when compared to JMEv4? In other words, what's NOT working (properly) in JMIv2, that WAS working (properly) in JMEv4?

And here's another question:

Since JMEv4's only issue (for me anyway) is performance, can someone please direct me to a link with a detailed how-to for converting to ext4? I'm assuming that simply performaing a file system conversion to aleviate the performance issues a little bit, will leave all my current system funtionality in tact as I know it now. Correct?

Please help!

raaleck I uninstalled the English Dictionary app from applications it was some 23MB file. But i still see the Eng. Dict. in task manager which is 8.25MB file. Now i see what's the problem. I will try to uninstall it from Titanium backup now. So now i already removed the Eng. Dict. app from application do i need to flash it again. What if i leave it like that would there be any problem? BTW +2 for your help.
[Galaxy Tab  Android Development] godwinvandamme:
I think he wants the 1.4ghz oc patch
[Galaxy Tab  Android Development] raaleck:
Tabing if it doesnt fc's after you uninstall the EngDic is ok, but in some cases if you try to use other keyboard it could fc the new keyboard since you removed the wrong app. But if its working well you dont need to reflash. It was just in case for dont get fcs in a future.

Again if its working well try leaving it without reflashing the original ROM.

Ext4 improves sdcard io perf. Mostly noticeable with angry bird loading time, other apps like titanium backup showed improvement as well. It works pretty good with roto jmev4. Just follow the first post of modaco kernel.

V12 was a no go for me on Roto's JMI v2, no problems so far using V10, this on USA T-mobile
[Galaxy Tab  Android Development] VeEuzUKY:
I have 2 questions:

- I actually had just flashed Roto JME Pre-Rooted Firmware v4 and now realize this V2 is newer (I naturally though 4 is higher than 2 so Im just extremelly confused as to how these ROMs are named). Anyway, what are the basic differences between these 2 ROMs and should I keep v4 or immediatly go for v2? So far v4 seems to work very well so Id like to understand if and why I should upgrade or just wait for yet another release...

- Is there a way to get rid of the useless STK Service? It pop-ups everytime the phone starts and bugs the living hell out of me. I know if I remove it with an app like SYSTEM APP REMOVER, I get into errors and crashes when making calls (at least it was so with the Samsung Stock ROM)

Thanks!

The CSC in the package I posted is the JMG one which doesn't have a wipe data command and when I upgraded my Tab, all my data was still present. I can't comment on 1.4ghz OC/UV as I have no experience with it.
[Galaxy Tab  Android Development] luisfer691:
Thanks for your rom Roto. i just intalled it on a P1000L/N Latin TAB. What I did was to replace in your TAR file the JM9 modem.bin, param.lfs and zImage. I also restored my Titanium backup and all apps are running fine.

So far so good. Also before flashing your custom ROM I flashed the original JMI following the same procedure.

Hi Folks someone has their tab with EXT4 and running @ 1.4 and using JMI?
[Galaxy Tab  Android Development] 09CarreraS:
I am having a issue with wifi on JMI. I noticed that at home I connect to WIFI just fine. If the TAb goes dormant for several hours I loose connection to WIFI. The only way to re-connect is to turn WIFI off and then turn it back on. The other issue is at work. I cannot keep a stable connection at all. My Iphone works just fine at work. Any ideas? I noticed that ROTO JMI uses the CSC from JMG. The JMG firmware had major WIFI issues. What does the CSC actually do?is there some coincidence?
[Galaxy Tab  Android Development] :
Fixed.,...
[Galaxy Tab  Android Development] VeEuzUKY:
I have a sinmple question I dont seem to find an answer for.

I just converted my tab with Roto JMI v2 ROM to EXT4 file system. I have to say performance increase is truly great.

Now, in the future when I change or update my current ROM, will the file system stay the same or its gets reverted back to the native RFS and then Ill have to reconvert it again to EXT4?

Thanks for the answer if anyone knows:)
[Galaxy Tab  Android Development] zyborg:
How did you convert it to ext4?
[Galaxy Tab  Android Development] VeEuzUKY:
OK, here goes, step-by-step (I'd love to learn in exchange how to install a ModaCo kernel becaus I have no idea how to do it... plus my question wasnt answered but... its OK). Anyway:

- Make sure you have an miniSD Card in with plenty of available space (it will be used automatically to backup your system during the conversion process)

- Get p1000-mck-r3-ext4-cwm.tar (the EXT4 Convertion Kernel)

- Connect the Tab in Downloading Mode to your PC via USB, start Odin3 1.7 and load the Kernel (click on the PDA button and select the p1000-mck-r3-ext4-cwm.tar and make sure PDA stays ticked after selecting the file).

- UNTICK Re-Partition check box and make sure the only boxes ticked are:

Auto Reboot

F. Reset Time

The PDA tickbox

- Click start and wait for PASS! (it will show highlighted green or Yellow on Odin)

- Now the Tab will restart and get stuck on the Samsung loading screen. This is normal. Turn it off by holding the power button for 5 seconds.

- Turn on the Tab again on into RECOVERY mode (Press Volume UP and Power On at the same time) and the EXT4 conversion will start automatically. The process will take up to one hour depending on how much stuff you have on your Tab. It took about 10 minutes on mine because I have a fresh install of Roto JMI v2.

- Once finished, click "Reboot System Now" (by pressing the power button).

- The reboot may take a while first time so be patient! Then, enjoy the speed:)

I went from quadrant 951 to 1665. Im thrilled! Best thing Ive done on the Tab yet:)
[Galaxy Tab  Android Development] Magaboo:

@rotohammer and ROM users

I have been watching and reading the GT threads for a little while. You have stood out as the man that should be able to help me out. I know you probably get a million PMs a day about stupid stuff so if you delete this I understand.

I am a techie. I currently have an HD2. I wiped winmo and flashed magldr and cwm. It currently runs a mytouch 4g rom that I love. I say this so that you know I understand flashing, cwm, etc....however I am no programmer.

I have a Tmobile galaxy tab. I LOVE IT. It runs great. I did root it. I have tried setcpu and it actually made my tab run like crap. I am hesitant to flash anything because I love my tab so much and it runs great. I am not interested in making calls from it so that is out, but I am a bit curious about your tweaked roms. The tab flashing process seems very involved and complicated compared to a phone.

I am actually an update freak! lol. I love messing and tweaking my phones, etc. My fiance says I spend more time messing with my electronics than I do with her. I would really appreciate your take on a custom Tab rom.

Thanks for your time

What modem (PHONE) are you using? I am at P1000XXJMA. And I get connection errors too that I did not see with orignal ROM, at least I do not remember that I got those errors. So might this be related to PHONE version and if so, is there any better/newer PHONE ROM?

Ext4 conversion

ok, I did the Ext4 conversion. It was very simple. Did it as described by VeEuzUKY, took approx 5 min for Backup and 15 min for conversion (I have a good 100 apps installed plus some pics etc). Reboots afterwards as usually. So far so good, it runs buttery smooth. I have yet to check what ext4 makes up for a difference in day to day usage. But without I got unresponsiveness from time to time with the stock launcher, or the keyboard which was pretty annoying.
[Galaxy Tab  Android Development] VeEuzUKY:
Good job:) The biggest improvement with EXT4 file system is I/O operations as it supports multithreading. Starting up applications, moving files around and any tasks involving read/writes are greatly improved. If you have some time you can read details about it here:

http://en.wikipedia.org/wiki/Ext4

As for your stock launcher (whatever phone you are running in with), replace it with LauncherPro. After being frustrated from day 1 with Android's stock launcher, I tried all laternatives out there. LauncherPro is the best by far... its like having a new phone. Try it:)
[Galaxy Tab  Android Development] Magaboo:
Thanks for your report

Hi pibach and thanks for your report. I would appreciate another report from you in a few days on the performance of your Tab. I'm still hesitant to convert my Tab to Ext4 until I'm sure that the conversion is really worth it because I really like Roto's JMI-v2.

Thanks

I am using Gt from europe. Right now i have the jmi and baseband P1000xxjmf

wondering if this is the rigt modem for europe.
[Galaxy Tab  Android Development] pibach:
I am using Samsung's launcher "Startseite". I have tried other launchers but did not see much of a difference, including performance. Or what does Laucher Pro do better than Samsung's launcher? Only sometimes I can see some lag, mostly after switching on from standby. Probably the tilt sensor tries to rotate the display forth and back? Or some other processes blocking resources? Java garbage collection? This may need in depth investigation to really figure out.

So far my Galaxy Tab seems to be less lag-prone with the ext4, however I still wouldn't deem it completely lag-free. The actual gain is hard to tell and would need a direct comparison. Anyway the ext4 conversion is risk free and very simple, so should be recommended to everybody, I think.
[Galaxy Tab  Android Development] Magaboo:
JMI -v2 and Ext4

Converted the Kernel only to Ext4 without any problem. Didn't loose any Apps or settings. My 'Quadrant Standard' before conversion: 1024; after: 1743! Looks very impressive, but I'm hard pressed to notice any gain in performance. At least now I can make Nandroid backups of my system.
[Galaxy Tab  Android Development] VeEuzUKY:
LauncherPro makes your "startseite" be much smoother and work infinitely better. There are many options to tweak speed, timings and the way things work. Its one of the best apps for Android and you should try it. You'll see Im right! The stock Andoid launcher is horrible.

As for your Galaxy still having lags, that means you have too many things running in the backgound you dont need and/or apps susing CPU cycles without reason. I suggest 4 programs that will solve all your problems. You need to have it rooted for all this:

- Task Manager 1.0.7 (let it run on background and configure apps you want to be auto-killed or ignored so that you only have running what you need)

- Startup Auditor 2.3.2 (disable all uncessary apps that start automatically every time you re-start your phone so you dont have excess apps running that you will not need to be started automtically)

- SystemApp Remover 4.12 (BE VERY CAREFUL AND DONT REMOVE ROM APPS YOU WILL NEED, however, disable whatever you dont need including system apps and services)

- CPU Usage Timeliness Free 1.7.1.0 (use it to see EXACTELY which applications are using your CPU and how much so you know exactely where your problems come from and which programs are interfering with good performance)

Macht das alles und die Tab wird perfekt sein! Viele Grüße:)
