That means the drivers on your PC might not be properly installed to communicated with the tab under download mode... try re-installing them and also switch to another USM Port if you have more than one. Sometime that solves it...
[Galaxy Tab  Android Development] VeEuzUKY:
Yeah, I will do that too but for now the 1.4GHz Kernel is still very buggy so, I want to wait till the bugs are out and then try it.
[Galaxy Tab  Android Development] :
what drivers should i reinstall?

And why is the tab stuck whit picture of a phone and computer? Cant do nothing whit the tab
[Galaxy Tab  Android Development] mifran:
hi this happened to me i cured it by pressing and holding down the power button then the volume down button let go of the power button then press and hold again eventually it will go to the download screen you can then use odin to flash the rom again

despite the stupied picture, I seem to be in download mode. Flashing rotos jmi v2 Right now, hope it works.

if it works you should make another attempt at EXT4? or is there something I should do differently if I want ext4.

Edit:

Happy happy time, its alive, =)

Did one more try whit ext4, Why dosent it work for me?

hmm. Can it be the file that we downloaded that it's the problem. But Its seems to work for everybody else. Why can't we get it to work.

You guys who get it to work. Did you add a file in the PIT field?
[Galaxy Tab  Android Development] gizzo:
Had de same problem, it was a corrupt p1000-mck-r3-ext4-cwm.tar file. For some reason, when I was downloading it with Internet Explorer, I was getting a much smaller file (under 1 mega). Then I redownloaded with Chrome, and I realised it was 6.5 megas, flash with Odin again, and everything went smooth.
[Galaxy Tab  Android Development] :
Ran into the same thing.

But I have now figured out what was wrong. It was so that my Samsung Galaxy Tab had "Signed / protected" bootloader and that was why it did not work.

followed this guide and now it went just fine to fix EXT4.

Shame on what? I posted the instructions on how to convert EXT4 files. Since when or where I claimed I invented anything or that is exclusive info? The same info is available on several sites and posts, I merely compilated infor I have gathered. If you have seen any claim here I exclusively "invented" ETX4 conversion please point out, otherwise, get a life!

Since i had to get my tab sent to samsung and they are sending a new one can i use this firmware..im sure they put the updated restrictions on the tab.
[Galaxy Tab  Android Development] p_hsieh:
I had similar failures yesterday, was able to flash back Roto JMI 2 Full version. You need to use the SGT-Bootloader-Patch-v1.00.apk in the first post of

http://xdaforums.com/showthread.php?t=888071 to 'unprotect' your bootloader. Afterwards, thinks should be fine.

BTW, after flashing to ext4 with Odin with success, it DOESN"T reboot normally, I waited for 20 minutes and nothing happened. I carefully read the beginning of the ext4 thread, and realized that you have to start manually the tab in Recovery mode, let your tab do it's backup and restore for the EXT4 conversion process, and things fly from there.

Hi,

I like the work done in the roto JMI v2 rom and I think its time that my tab lost its virginity...:-) couple of questions though -

1. Is the phone function enabled in the rom by default?

2. There is local app from samsung called "Ag Indian newspapers ". Anyway to back this up or copy it so that I can still have it after changing rom's?
[Galaxy Tab  Android Development] thenewak:
Not sure bout your first ? i was wanting to know the samething and yes you can back up ur apps. if your tab is rooted you can find the .apk save it and reload it when your done flashing.

Thanks for the tool list, I am going to check those. And App Launcher Pro. Is there a way to migrate the screen configurations? Or do I need to move all the app icons again?

But I think it is not the launcher itself causing the lag, but some background process. I also have numerous FC crashes...
[Galaxy Tab  Android Development] rangercaptain:
that is another screen for download mode. Just reconnect tab to pc, check your settings in Odin, and reflash. Good luck.

Hi all,

Am thinking of flashing the roto ROM over my stock...was wondering, do you folks think its okay to flash the Modaco ext4 kernel along with it? Or does roto provide that already?

Thanks
[Galaxy Tab  Android Development] rangercaptain:
The Roto rom will replace your stock, because you will need to do the full install. The ext4 rom will reformat your internal memory to the ext4 system and replace the Roto rom.
[Galaxy Tab  Android Development] codington:
If you really want EXT4 format, just flash MCR kernel and ROM together - they are made to work together. What you are trying to do will probably work, but there will not be a lot of members in the community able to support you if you run into problems. I tried MCR JMI ROM with EXT4 kernel and came back to Roto that same day. It is a rather an involved process if you ever want to switch back to Roto ROM (or non EXT4).

I've never run Quadrant or Linpack as I don't need software to tell me if the ROM is performing better. Sticking with Roto JMI v2 with CF Root 2.3 - as I have yet to find anything better. Of course YMMV. Good luck.

1.) you can either flash v2 which is without the dictionary or remove the dictionary yourself with a program such as root uninstaller. I did the later and it worked fine.

2.) Are you sure you did set it up correctly? It works fine for me.

You simply have to

- flash Firmware JMI (PIT, PDA, MODEM, CSC) with Re-Partition in Odin

- then, re-flash Roto's ROM without the .PIT (and without Re-Partition)

That worked for me :)

Strange thing i found out after installing this rom.

1. The touchwiz orientation is always upside down and i can't control it. I am not sure if this has something to do with Modaco Kernel or just because i calibrate the display and messed up the default calibration.

2. if i do Adb install packagename i got issue with pm not found but i did a manual amendment to the /system/bin/pm and got it working again.

If anyone knows solution to the first issue, please let me know. Thanks.

I think you can do a roto backup and get the modem.bin for flashing. It works for me.

HI all,

I've just bought a SGT Asian version (Vietnam) with the original ROM: P1000DXJK2.

I did flashed to Roto JMI v2 successfully. After that, I follow the instructions from here to convert filesystem to EXT4 http://xdaforums.com/showthread.php?t=957855. My SGT worked smooth after that.

Then I just wanted to test to re-flash my SGT back to original ROM and I succeeded.

However, I love the performance of Roto ROM so again I re-flash to Roto JMI v2.

The problem is: after successfully re-flash back to Roto JMI v2, I cannot convert the filesystem to EXT4 as I did before. My ODIN 1.7 FAIL and my SGT showed the screen with a phone connection to a computer.

Does anyone have the same problem? Is there any resolve?

Thanks.

Hi rotohammer

can I mix and match zimage factoryfs cache dbdata modem param from various devices?

my objective is to create a CLEAN fresh rom for Hong Kong ZHJJ1/ZHJK1

i.e.

factoryfs.rfs from my ZHJK1 - settle the language issue

modem.bin from my ZHJK1 - settle the telco

cache.rfs from rotoJMIv2 - clean

dbdata.rfs from rotoJMIv2 - clean

param.lfs from rotoJMIv2 - clean

zimage from koxudaxi's hktw_2_3 being greedy wanting 1.4Ghz

is it OK or SIN?

and to TAR them, can I just lazily move them in and out using winrar over some other TAR file?

or must TAR be created from the command you provided?

or simply do them over using Heimdall, no need TAR at all.

thanks thanks thanks for your help ? :)

for some reason with this rom I am noticing an issue with market apps, I have installed/upgraded a bunch of apps, Google Maps, Chase, Google voice.

For some reason the market installs them but then does not know that they are installed, showing up with the "Free" button to install them again.

I am wondering if its something with my efs folder.

I gotta hand it to you Roto, this rom is wicked fast.

However my tab refuses to pair with my BT headset now. Should I look at factory resetting? I've already cleared the cache.

Before people say use search, I've already tried and it's currently broken, even tried googling through the thread without much luck. I pretty much live off this headset and I'd be crushed if I had to revert to JMC in order for it to be usable.

You need to do a factory reset to get it to work again.

Is there a way to flash back to the stock rom if I want, or there is no way back?

Depending on the firmwares involved, a lot of the time you can mix and match pieces, but theres only one way to know for sure, try it.
