[Galaxy Tab  Android Development] FredBE:
I had access to a brand new Tab yesterday (Product code: CPW) and it was pre-loaded with PDA JJ3, Phone JID.

Kies proposed an upgrade to PDA JJ7 (Phone & CSC JJ5).

So yes, JJ7 is still the last official firmware in Europe.

PS: Firmwares are all fine till JK5 but I would suggest not to use JM6 which is somewhat 'weird'...
[Galaxy Tab  Android Development] alias_neo:
Do you know or does anyone else know which firmware i can flash to regain Kies update compatibility. Im on JJ7 now but Kies doesn't recognise it as a valid firmware saying that's it can't be updated rather than it is upto date.

Id like to downgrade and get back to JJ7 via Kies.

Any suggestions?

Im on a generic UK Tab (PCWorld)
[Galaxy Tab  Android Development] cezarc1:
Yes,the browser is MUCH smoother. Redesigned readers hub, email, new features in browser. Worth flashing!!!!
[Galaxy Tab  Android Development] clubtech:
JM are usually test firmwares...like the sgs had JM firmwares but I agree the letters don't make much sense.

Anyone here with the at&t tab who flashed this successfully ?
[Galaxy Tab  Android Development] risq:
I just selected the PIT file and started, no other files.

It then came straight back to life ;)
[Galaxy Tab  Android Development] risq:
Ok - Well there are some differences for me, although I'm not sure if there will be for all of you.

I was previously running JK5 which i upgraded to from JJ4. On JK5 i noticed there were hardly any widgets, although they've now returned on JM6 for me....

There's also quite a few new ones....I'll get it back to how it was and let you know if I notice any performance differences.
[Galaxy Tab  Android Development] riz157:
help needed tried to flash this but got stuck and turned phone off now nothing....help. Cant turn on no download mode ..pls help
[Galaxy Tab  Android Development] risq:
Ok - firstly try not to panic.

I take it you see the screen with the caution sign and the computer? First of all, try flashing just the PIT file to the device. Hit start and see if it passes. If you ticked auto-reboot, phone should hopefully start up OK?

If not, re-flash it and make sure everything is set correctly.
[Galaxy Tab  Android Development] risq:
OK - anyone else who has flashed to JM6 - Does Z4root now crash when you try to re-root the Tab?

Just done *#1234# and the It shows up the Phone Version as JM6....but CSC and PDA versions are blank - anyone know why this would be? Not seen that before.....Tablet is functioning perfectly fine and I can make calls.....odd.

Update:

Rooted it with SuperOneClick!

Update 2: For the life of me, I cannot re-flash JJ4 on the device.....it always fails on boot.bin. I've tried a few others too, with no joy. I'm obviously a little mythed as to why CSC and PDA are showing as blank, i literally have no information for those slots at all.

Seems very odd to me. Anyone have any ideas?

I've got a UK Spec Tab from CarphoneWarehouse. Any assistance would be much appreciated.

Anyone on JM6 - Can you tell me what it says for you when you do *#1234#?

Thanks
[Galaxy Tab  Android Development] clubtech:
When you flash back to JJ4, do you select repartition and select the JJ4 PIT file?
[Galaxy Tab  Android Development] risq:
Hi,

Where is this JJ4 PIT file? Can you possibly link me? Thanks
[Galaxy Tab  Android Development] clubtech:
When you downloaded the JJ4 from samfirmware.com and unziped the file - you should the see the PIT file to use along with the other firmware files.
[Galaxy Tab  Android Development] risq:
Yep,

I used the one with the files. P1_no_PIT - which worked fine when I upgraded to JJ4 initially.

However, as soon as I flash now, it checks the MD5's, goes to start flashing and immediately fails on boot.bin.

Could the dbdata.rfs.tar knackered the set-up of the phone if it was originally from a US JJ4 phone? Just seems odd that it's doing this now. Yet it shows the PHONE VERSION but not the PDA or MODEM....

Pretty confused and pretty annoyed right now, as I've done this a thousand times without issue.
[Galaxy Tab  Android Development] risq:
Well it seems like the device isn't booting at all now, just got the Phone ---! -- Computer screen when connected to AC power. But if I try to power on the tab without AC power, screen stays black.

Not sure if something gone horribly wrong inside of the tab, as I say , there's been no issues up till now.

Will have to take it back to Carphonewarehouse tomorrow if need be....the only kick in the teeth? My 7-day refund expired yesterday - so hopefully they'll change it for me.....who knows?
[Galaxy Tab  Android Development] clubtech:
The Phone ---! -- Computer is solveable.

There is a way to get it back to download mode.

Try turning off your Tab.

Then press the vol down + power until you see that "Phone ---! -- Computer " and keep pressing both buttons while you see it. i think at some point it should switch to download mode.
[Galaxy Tab  Android Development] clubtech:
1st post updated with the latest info i gathered on this rom.
[Galaxy Tab  Android Development] antz88c:
Flashed it successfully
[Galaxy Tab  Android Development] rgbc:
clubtech did you flash this rom, I wasn't sure from your updated post. It seems like the bricked tabs have been north american, and the successful flashes european.
[Galaxy Tab  Android Development] clubtech:
I have flashed this successfully on my at&t tab.
[Galaxy Tab  Android Development] clubtech:
How did you flash this please?

Step by step if you can (as you seem to be the only one who got a displaying CSC and modem).

Please note your device model, the firmware you flashed form and how did you flash with details.

This will help everyone.
[Galaxy Tab  Android Development] geek78:
My unlocked European tab is now totally bricked : black screen even plugged ..

I have used the last odin, no répartition, no pit...
[Galaxy Tab  Android Development] antz88c:
Im using APAC SGTab and official DXJK2 (updated via Kies).

I did a hard reset first before i flashed to JM6, after ODIN my SGT went back to download mode, i just entered recovery mode and it booted normally.

After, installed CSC XEU. Done.
[Galaxy Tab  Android Development] rotohammer:
The display timeout works fine on my two Tabs in JM6. But I know someone else who had the same problem, so there must be an underlying cause. I'd try performing a factory reset to see if that clears up the problem.
[Galaxy Tab  Android Development] Handymeister:
Ok, what about my CSC-Problem? Can I use the Tab without, when I won't use a SIM-Card?

Thanx

Handymeister
[Galaxy Tab  Android Development] FredBE:
Well, in fact I wanted to do the same and I ended up bricking my Tab but that's my fault.

I have a full dump of that brand new Tab JJ3 firmware (I followed the method the US people did to make a stock firmware in another thread here).

With that dump I made a first .tar including only cache.rfs, dbdata.rfs, factoryfs.rfs, param.lfs and zImage.

I flashed that on my "JJK5" Tab without repartition, just as a simple PDA file: it worked all fine. I had the new UK applis installed after which I never saw before.

But then, I went overconfident and was also working on 2 computers at the same time.

I thought it was not possible to brick a Tab if you didn't re-partition but yes you can...

I didn't try Kies first to see if it was back to 'upgradable mode' :(

After the initial success I wanted to directly flash more of that original firmware and added, I think (not even sure...) boot.bin, modem.bin and Sbl.bin in the .tar and just re-did a simple PDA only flash.

Odin 1.7 succeeded to flash that but the Tab never booted again, not even in recovery or firmware download mode.

I would have posted a back to Stock firmware yesterday like the US people did but... I messed up as you can see.

Still, that first flash I did was maybe enough to put it back in Stock mode but I will probably never know.

I don't really want to take the risk to post those files and have people bricking their Tab... it's tricky as you can guess.
[Galaxy Tab  Android Development] rotohammer:
Try it! I have no interest in carrier customizations, so the fact that this firmware has none at all suits me perfectly.

Having no CSC isn't a "problem", its just not having a CSC :)
[Galaxy Tab  Android Development] rotohammer:
Never mess around with boot.bin & Sbl.bin (boot loaders). I always remove them before flashing any firmware just to be safe, and I would never distribute a firmware with those files present.

Unless someone tells you definitively that a firmware requires a particular boot loader, there is absolutely no sane reason for flashing it!

A failed bootloader flash is the ONLY way to permenently brick your device!
[Galaxy Tab  Android Development] Handymeister:
I tried and everythink works fine (without the display-timeout), only the market can't find some some apps, but this is not a problem for me.

My english isn't so good, so pleas explain what do you mean with "so the fact that this firmware has none at all suits me perfectly"?!

Thanks

Handymeister
[Galaxy Tab  Android Development] Volker1:
I've been using my tab with "missing" CSC with SIM and Wifi and have not found any problem due to this. You can only lose with carrier customizations.... :D
[Galaxy Tab  Android Development] Volker1:
"Die Tatsache das diese Firmware keine [Netzwerkbetreiber veraenderungen] hat passt mir ausgezeichnet!"
[Galaxy Tab  Android Development] tw1nz:
Works fine for me!

Root by Superoneclick - And works just fine.

- My problem is now, that i dont have the Samsung keyboard with Danish.

how can i get that?
[Galaxy Tab  Android Development] rotohammer:
I prefer not to have carrier customizations. You should too. If you do no't know what a CSC is, then Google it, or try to find somebody that likes having a particular CSC on their device.

Just because something is missing does not mean it is bad! I'm missing a brain tumor as well and I'm quite happy about it!
[Galaxy Tab  Android Development] alias_neo:
Bit of a serious way to put it :eek:
[Galaxy Tab  Android Development] hartyshow:
Hi,

I have a big problem ! After flashing, all preccess of application crash !!

Any idea ?
[Galaxy Tab  Android Development] Mr.Kakarot:
I removed the apps and reinstalled them, worked so far... I did not wipe or factory reset... which we probably should?

Also, if turned off my wifi with my rogers sim card in it... I can still make calls and whatnot, but I do not see 3g... How do I access data off my rogers sim?

thx
[Galaxy Tab  Android Development] rotohammer:
Crashing problems are usually solved with a "Factory data reset" in Settings->Privacy.

If not, then try the Roto-JM6 firmware listed in my signature.
[Galaxy Tab  Android Development] hartyshow:
@Mr.Kakarot Thanks for your quick answer. I have made a factory reset and now it works better ;-) I just need re-install all my application...
[Galaxy Tab  Android Development] Handymeister:
:-) Thanks

For some reason MMS is not working on ATT.
[Galaxy Tab  Android Development] swgamez:
After flashing my GT the phone audio is low everything else is fine, any help would be appreciated.

Thanks
[Galaxy Tab  Android Development] clubtech:
I noticed this as well if u use the bell radio.

It only affects the speaker phone sound level. Normal audio is fine and Bluetooth volume is fine.

If u must use speaker phone make sure you turn the volume all the way up - then it will be louder.
[Galaxy Tab  Android Development] swgamez:
ok thanks for the help:D
[Galaxy Tab  Android Development] clubtech:
Sorry I had a typo in my last reply .

I meant to say turn the volume NOT all the way up.

Turn it all the to one level before the max it can go. You will notice the volume for some strange reason is louder when not turned all the way to the Max.

It is related to the Bell radio. If you flash the original jm6 radio the problem will go away.

The bell radio also causes the GPS to be not as reliable.

I have no fix for that yet.
[Galaxy Tab  Android Development] slaia:
Everything is working except Google Maps

Thanks to this forum I could flash my GTab successfully. The only mistake I did was I forgot to do factory data reset. So almost all apps crashed. But after I did the factory data reset, reinstalled all apps, restarted, and everything is fine.

The only problem I have now (I've just found out) Google Maps crashes everytime I run it. I've browsed this forum for maps , but it seems that nobody else has got the problem. Any idea?

Thanks in advance.
[Galaxy Tab  Android Development] tomhster:
Had the same problem. Go to downloadsection in Market, uninstall updates, then reinstall. Problem fixed.

For those who lost dolphin multi-touch (Pinch to zoom)

For those of us who like the dolphin browser and was a bit disappointed at losing the pinch to zoom feature. Here is a little light. Dolphin are making a much faster lighter version with plenty of great features including gestures, pinch to zoom etc and it all works on my JM6 Galaxy Tab. Pinch to zoom etc and is very fast. Now those who like dolphin can now appreciate this rom.

Here is the link: http://blog.dolphin-browser.com/201...r-mini-preview2-for-android-faster-than-ever/

Don't know if final product is free or not. And dont know if there is an expiry date on this preview. But it works and i'll def buy the final release.

Hope this helps

Phil
[Galaxy Tab  Android Development] Croak:
I've been using Mini for a few days now, off and on. Doesn't suit my needs the way the full HD did, takes a lot more taps to do basic functions, doesn't have plugins, etc.

It's a great little browser if you're using a Hero or Eris or some other underpowered Android device, but it doesn't hold a candle to the extra functionality of Dolphin HD (and how well HD works as a tablet browser). And on the Tab, it's not really any faster than HD was, so even the "speed advantages" aren't there.

I regret the jump to JM6 just for losing the PtZ on Dolphin HD. Sadly, I'm one of the early "repartition" JM6 adopters and can't roll back.
[Galaxy Tab  Android Development] deekdeek:
Thanks for this roto just flashed my rogers tab so far so good, just testing it out now.

thanks for the simple directions, these are hard to come by. especially for a newbie into the Samsung devices.
[Galaxy Tab  Android Development] clubtech:
I think you can try and roll back but don't select repartition.
[Galaxy Tab  Android Development] mlaccetti:
Threw this on my Rogers branded Tab, and it works like a charm. Got full connectivity and a working phone - stellar!
[Galaxy Tab  Android Development] xoltrix2000:
Question: Why did we have to use CSC file P1000OXAJM6? I'm just curious because at the Samfirmware.com site it only notes to use the PIT file only if flashing other stuff with it. Is the CSC file necessary?

Reason I'm asking is because I was thinking of downgrading to another regions firmware (arabic) and it's a bit older then it.
[Galaxy Tab  Android Development] kingskidd268:
My God you save my Tab, I was looking all over for this.
[Galaxy Tab  Android Development] beemerTPPC:
Upgraded without issues in my european JI4 Galaxy tab.

I've unninstalled all apps ad installed again. No need for a full reset.
[Galaxy Tab  Android Development] bradlaue:
Hi roto,

Can this ROM be flashed on top of any pre-existing version, or does the Russian ROM (JJ4) need to be applied first?

Thanks in advance!
[Galaxy Tab  Android Development] rotohammer:
Yes, I've got reports that It successfully was flashed over stock T-Mobile firmware even. Thats was the whole point of me making the modified package.
[Galaxy Tab  Android Development] Freak:
Roto, Is MMS working on your ATT Tab?
[Galaxy Tab  Android Development] soli128:
I have the same problem, but my solution was to make a APN, the settings got I from here

samfirmware.com / apnsettings.htm

Perhaps there was a APN before I flash with JM6, but when I make one manually 3G is working, so I am happy now, but next time there come a new firmware I will wait a while :)

/soli
[Galaxy Tab  Android Development] rotohammer:
It was until I cancelled AT&T service on Saturday. Any issued with internet access, text or mms not working is simply a matter of setting a new APN in

Settings->Wireless->Mobile Networks->Access Point Names

This ROM doesn't have every APN in its database, and you can't expect any one firmware to have every APN for the whole world unless someone maintains the data file.

This isn't a quality issue with the firmware, its a matter of practicality. Someone should start a thread called "APNs From Around The World"
[Galaxy Tab  Android Development] Freak:
Thanks, just wanted to make sure it was the APN and not the rom. Cause everything else works.

Question on enabling 3g for Tmobile tablet

I have a Galaxy Tab for the UK which works perfect with Tmobile...except for 3g. I understand the radio hardware is different.

I also have a Tmobile GT...rooted. Now comes the typical question.

So I can flash the tmobile GS and hopefully (by following instructions) it will work to make phone calls. I can also somehow flash it to have the Euro rom...correct?

On this post you mention no 3g onn Tmobile flash but, on ATT flash (for the ATT GT) you can have 2g and 3g.

Will there or is there at this moment a way to flash the Tmobile GT to work on 3g and make phone calls?

thank you

============================================================
[Galaxy Tab  Android Development] rotohammer:
So what you're asking is can I somehow rephrase what I wrote in that post that you quoted, in such a way, that its even more clear than it already is? No.
[Galaxy Tab  Android Development] flo7002:
So I flash my ATT tab with this firmware and the Bell modem, data/phone works fine, although my data speeds are really bad for some reason.

My other concern is that my ipad's sim with the unlimited data doesn't work anymore. It was working great before the flash. Is there any fix for this? cause I would like to keep using that, or should I just go back to the stock ATT firmware? I wanted to flash the euro version cause people have been saying it's running smoother, etc. Thanks!
[Galaxy Tab  Android Development] Kardiobc:
T-Mobile Tab flash

Rotohammer....smiling....thank you for making the obvious even more clear and sorry for the redundant question.

There is a "rumor" that Tmobile may be rolling out the phone capability in Jan. of 2011. We shall see. At the moment I am using the Euro tab and it is working great. I am a complete newb that is slowly trying to learn the ways of flashing ROM.

Once again thank you for your help.
[Galaxy Tab  Android Development] mywingtophone:
is this jm6 older than the deviant jm5-beta2 ?
[Galaxy Tab  Android Development] PrinceOD:
Roto, you are a champion among men! I just made my first successful call with my Bell Galaxy Tab (after a successful backup per the instructions in your sig).

Awesome stuff, love this thing more and more every day I have it!

Clean upgrade through JM6

Just to add to the list of experiences here, I upgrade from a stock Rogers GT, performed a factory wipe from the recovery mode and installed JJ4, JK5 and JM6 in succession. This went very smoothly and at the end, I ended up with full phone and 3G, without installing the the Bell modem file.

I am curious whether the current posted ROM, actually includes the Bell modem components.

Either way, I am getting an "H" or "3G" status for data transfers and a tablet that is no longer crippled.

Thanks to all at XDA that contributed to these instructions.
[Galaxy Tab  Android Development] STEEPSIDE:
Do you still have 850 band, on my I9000 if I flashed all european firmware I would lose this band and have terriable service in fringe areas. I did the same as you with my GT but flashed the Bell modem and I have the 850 band 5 even with Telus after using Rotohammers procedure for unlocking the tab. Just a thought?
[Galaxy Tab  Android Development] PrinceOD:
Just a follow up, I'm finding that the phone is working great, but the people I've spoken with are complaining that I sound too loud, I also get some pretty bad echoing from their phones. Also, I checked battery usage in Spare Parts and noticed that this revision appears to have a buggy version of the Gallery app which starts using the sensor and won't let go (I only checked that because I'm coming from a Galaxy S, where I had some pretty bad battery life issues because of that).

Any ideas on either of those issues? I'm going to do some of my own investigation and if I find any answers, I'll post back here!
[Galaxy Tab  Android Development] daniel.weck:
This issue is not specific to the Tab or the JM6 ROM.

Use Number22's custom Gallery3D.apk build (do a search on XDA), and you'll get the sensor bug fixed as well as many other improvements.
[Galaxy Tab  Android Development] PrinceOD:
Awesome, just installed it and it seems to have done the trick! Now on to the call quality... I was reading that bluetooth is an issue for some models, is that at a hardware limitation or software that this has solved? (I'd just investigate via trial and error, but my headset is out in the car, which is under 3' of snow right now because we've had a freak 3 day blizzard)
[Galaxy Tab  Android Development] kingskidd268:
Thank you my friend this help me with my T-mo tab. this need to be posted up.
[Galaxy Tab  Android Development] dubmusic:
Checking which UMTS bands are supported...

How can you tell if the 850 band is still supported in the currently installed ROM?
[Galaxy Tab  Android Development] jay_jay_n:
Same here lol, it helped on the different file names where exactly they go in odin
[Galaxy Tab  Android Development] STEEPSIDE:
From phone menu type *#0011# and the screen that pops up will tell you what band you are on, best thing is to try the tab in a few spots and it should switch from 1900 to 850 depending on signal strength. Try walking around your place or inside and outside. Mine switches regularly depending what room I am in.
[Galaxy Tab  Android Development] dubmusic:
I have now tested this and have confirmed that my GT will switch to 850 when required.

No Bell modem file

Very cool.
[Galaxy Tab  Android Development] grellanl:
Good results here, definitely feels much smoother all round, particularly when launching/closing the browser, and don't see as much stuttering while Gmail updates in the background as before. Did select repartition, unlike with previous versions.

Euro/UK model unlocked Tab.

Had to wipe /data from recovery after flashing due to all apps FC'ing, as expected. Just restored using TiB once this was done.
[Galaxy Tab  Android Development] Croak:
Anyone have a handy copy of the JK5 or JM6 modem.bin?
[Galaxy Tab  Android Development] Alcibiade:
Would be worth being put on the first page, much clearer than anything else found in the thread (At least for AT&T users like me)

So, this way we don't need to go through the Russian version flashing ? Just your firmware + the modem, right ? (Seems to have worked for me)

two quick questions:

1. I noticed that when I boot I now get a black screen with... an ugly vertical white bar on the right of the screen... Am I the only one experimenting this ? (Yes I went to settings, Privacy Factory reset)

2. After booting it seems I need to switch on and then off in order to access my main screen (otherwise the screen remains black). I kind of recall someone mentioning this in one thread but just can't get old of it...

*** Edit *** OK found the post related to this and it seems I cannot go straight to rotohammer version from my AT&T fresh ROM (At least since the problem seems to be the same as the one experienced by users flashing directly Clubtech ROM, I assume it's the same issue and this answers my very first question...
