ok .. so i have a perma rooted phone .. but still get some errors when running terminal . so i want to try the secondary method of rooting .. thats they why

I have 4 specific questions if you dont mind

1) when i run the SECOND line of code in adb .. and i do it in ADB shell .. it says "permission denied". hell i do this in "su" and it looks like it runs fine. not sure which way is right really

2) also .. another question .. when is says to copy the misc.img file to the comp .. are we to leave the original on the SD card or remove the misc.img from the card?

3) when we edit the misc.img and save it as miscnew.img .. we are supposed to move it back to the root of the SD card right? even though it doesnt say what to do with it after editing the file.

4) Finally when i boot into Hboot ... it scans and says "loading .. no image"... or something like that a few times in a row and then just gives me the standard fastboot options

- yes i have tried to remove the .zip at the end of if already, and the rest is spelled right.

also the wording with the mount and unmount seems to be very unclear to me .. i dont know if it means mount sd card to the comp to tran files or mount sd card to the phone or unmount sd card from the phone ... help with this too would be great

and maybe a re-done tutorial with the changes would be nice as well thanks

any help on this would be appreciated greatly

do you already have the OTA? are you running version 2.2.1 that is... ??? if so this is gonna downgrade your phone and then you will have to follow my instructions in the other post about forcing update and rerooting... you're better off not doing any off this and running fix permissions on clockwork, because this process is gonna take an hour or so of your life and the second half of my post might be good enough... or running recovery... just something to think about... basically what I'm saying is I don't think this is the post you think it is
[myTouch 4G Android Development] Strapt:
yes sorry .. i forgot to say that i have the 2.2.1 .. i know its a downgrade .. but then i will follow that how to force the OTA and then re-root using the new method .. i am currently trying to figure out either .. A) how to get this to work right or B) re-do what i did to my bootloader .. now no matter what it does that damn no image file even after setting the misc.img back to the right nubers and then reversing the second code line.

I have ran the fix permissions previously .. i will try it again .. but in terminal i cant get free to work . says permission denied .. so something is not right . that is why i was wanting to start over and do it again
[myTouch 4G Android Development] Strapt:
question . what exactly does these codes do? i know that after i run the first one i see the misc.img ..

is it creating the image there .. or did it pull it off out of the phone somewhere?

then the second line of code .. is it pushing the miscnew.img into the phone?

do we leave any of the .img files on the sdcard when rebooting?

i get the .img file .. i edit the numbers in a hex editor... i save it as miscnew.img and leave the original misc.img off the phone, then i place a copy of miscnew.img back on the sdcard and the orig on the desktop, then attempt to run the code below.

this command here as it says should be done thru the adb shell .. but when i do it in adb shell at the $ .. i get permissin denied. but if i do it at SU then it looks like it goes thru .. not sure if that makes a difference.

mine does not find it .. i have removed the .zip at the end and nothing .. it just scans for it and then takes me to the standard fastboot options.

im really not sure what is goin on .. any help would be great thank you
[myTouch 4G Android Development] slhpss:
the first one writes the contents of /dev/block/mmcblk0p17 to misc.img and the second one writes the contents of miscnew.img back to that same device
[myTouch 4G Android Development] Strapt:
ok cool .. i thought thats what was going on .. i got a question then

I tried to push the original img numbers back into the device to reset what i changed... so i just replaced the miscnew in the code and did that .. looked like it ran

so after i rebooted and then i pulled it from the phone using the same first code ... when i open up the .img file .. its still the manipulated numbers of the miscnew.img file

any idea why that would not push it back to the phone if thats what it is supposed to be doing?

and any reason why it wouldnt be finding that PD15IMG.zip file?

thanks again
[myTouch 4G Android Development] slhpss:
it's not moving the file... it's more like a low level copy
[myTouch 4G Android Development] Strapt:
So any ideas as to why it won't find that .zip file? It never asks me to flash it ...why does it have to be done from fastboot and not just flashed liked a regular one in recovery?
[myTouch 4G Android Development] Strapt:
dd if=/sdcard/miscnew.img of=/dev/block/mmcblk0p17

when i run that code i am getting a "cannot open for read: permission denied" when i run it thru adb shell and the sdcard is mounted as a disk drive on the phone

now when i run the same code as above but this time the card mounted as charge only on the phone i get the same response as above

but when i type in "su"

i run it thru with the charge only and it transfers information and it says 262144 bytes tran in .168 secs

then i run it while mounted as disk drive and run it

i get the error "cannot open for read: no such file or directory

so wit this being said .. the instructinos say to run that code thru ADB SHELL and i cannot get it to work in adb shell only in SU and when in charge only modeis this right?

and if so then why is it still not finding the update when i boot into the fastboot??

NOTE **

i check the system info in fastboot and it shows the 1.14.531.1 as it says in the guide so i guess that works.

so something must be wrong with the update then .. or this guide
[myTouch 4G Android Development] Kline:
Guide is fine; used it multiple times. Check you are doing things exactly. If adb shell will not let you SU, then you need to fix your superuser apk perms. If you can't do it via adb shell, it works just fine via Terminal Emulator directly on the phone. Shell is just easier as your PC has a full keyboard vs the softkey.
[myTouch 4G Android Development] Strapt:
i can get su permission just fine thru the terminal .. the OS version of the phone shows the downgraded version that i altered witht he hex .. but it just will not find the PD15IMG.zip and ask me to flash it during the boot in fastboot is the problem
[myTouch 4G Android Development] Kline:
Verify you named the file correctly. If you are using any version of windows from about 98 and onward, it is the default behavior to "hide known file extensions". So your file is probably named "PD15IMG.zip.zip". Verify the name of the file using a file manager directly on your phone, unless you know how to disable the "hide known file extensions" in Windows (Google it).
[myTouch 4G Android Development] Strapt:
Ya I have gone back and fourth with that hide/show known extension types in windows ... I Even still removed the .zip and it just showed up as file on the phone ... Hell even tried .zip.zip too ...and nothing has worked.

Which is really weird. Im pretty sure everything else went right since the software version in fastboot shows the downgraded version that I had to edit with the hex editor.

But in the phone under settings it shows up as 1.17. Not sure if that was supposed to change too or if only matters what it shows in fastboot under the OS version.

This stuff right here is exactly why I want to undo the root and try the other method and it doesn't seem like I can for some reason.
[myTouch 4G Android Development] s10shane:
hey has anyone yet to receive the 2.2.1 ota update yet? jw
[myTouch 4G Android Development] Strapt:
question .. so .. after having all the issues with the permissions .. which i found today do NOT exist when i am in ADB in recovery .. I can run "free" in shell and work fine .. but with the phone on .. i get permissin denied ...

question 1) anyone know why that would be happening above like that?

question 2) even though i have done the downgrade properly in adb it still will not find that damn PD15IMG.zip file ... so does this really need to be flashed there in fastboot/hboot screen or can it be done thru recovery and then flashed like any other update? ... or thru adb?

question 3) if its not findidng the PD15IMG.zip in Hboot .. does that mean that the sdcard is not mounted or something causing it to not find it?

Can I do this without ADB

I do not have access to ADB, everything I have done was through the terminal. I want to go back to stock rom unrooted and everything but I dont know how. Can I do this without ADB.
[myTouch 4G Android Development] slhpss:
you should be able to, but if you have a typo in your dd commands it could really screw things up...
[myTouch 4G Android Development] rllong1:
Ok, long story short. I do not have access to adb because my pc will not let me run anything from the command prompt because I am not the administrator. Is there another way. Thanks though.
[myTouch 4G Android Development] slhpss:
like I said it should work in terminal, but be careful not to mistype anything
[myTouch 4G Android Development] jessicamartoranA:
Not to be stupid but can I used clockwork to flash this Rom to stock Rom cause I'm on a custom Rom now and need to send my phone back to t-mobile
[myTouch 4G Android Development] slhpss:
just follow the instructions...
[myTouch 4G Android Development] likeitnot:
So I have to send my device back and it was rooted so I just went ahead and did this so I'm guessing I should be okay. I just hope so lol. BTW this works without a hitch, thanks again!

ALSO I planned on flashing this back and then turning S back to On but I see flashing this automatically turns S back to ON so I guess all I had to do was this woohoo.
[myTouch 4G Android Development] slhpss:
FYI - it only turns S=on if you haven't done the radio S=Off if anyone else is reading this.
[myTouch 4G Android Development] likeitnot:
Oh okay my bad. Yeah I just did the S-OFF original thread not the new one even after permaroot. Thx though because I forgot that that was something people might have done!
[myTouch 4G Android Development] sheek360:
Can you post a link to that thread ?

I successfully downgraded but hboot is still 86.0

Is that what its supposed to say?
[myTouch 4G Android Development] XxKOLOHExX:
The only numbers I have in my misc is 2.09.1800.1 , Do I change that?
[myTouch 4G Android Development] nafeasonto:
Guys does ANYONE have an updated link for the stock rom PLEASE. ALL THE LINKS are dead, IN EVERY GUIDE. IT's annoying the crap out of me. Since Megaupload has been taken down, I would like to downgrade my device so I can root this thing

[myTouch 4G Android Development] :
Hi ,I use your downgrade thread and for reason clockwork Rom manger is not able to flash recovery .imgs ,or list what Rom I'm on and Rom manger can't determine my device. once I downgrade is there away to revert back or delete miscnew.img so I'm able to use clockwork Rom manger
[myTouch 4G Android Development] mikeschevelle:
thanks :)
[Galaxy Tab General] thefoss:
it's been brought up in other threads, but I'll get right down to the meat of it: Are the US variant tabs capable of sending and receiving cellular voice calls and texts, hardware wise? In other words, is the hardware there and just disabled by software, or are they physically incapable of this function?

Im on Sprint now, but my goal is to switch to T-Mobile or ATT so I can swap sim cards from my phone to a Tab at will. (yes, I know the tab takes a micro sim, but there are adapters). If the cellular radio is left intact, then rooting and flashing new firmware could enable it. Am I right?
[Galaxy Tab General] foxmeister:
I don't think anyone truly knows if the phone functionality can be re-enabled on the US Tab, but are you sure the US Tab uses micro-SIMs, because the European one just uses standard ones?

Regards,

Dave
[Galaxy Tab General] Step666:
Engadget reported that some T-Mobile US customer have been sent microSIMs recently, which lead to a spate of rumours about the iPhone4 but it was supposedly then confirmed that the microSIMs are to do with the Tab instead.
[Galaxy Tab General] jdmadonna:
I spoke with T-Mobile tech support early this morning... the tech said according to the trouble shooting guides that they have to use... the hardware is there, but voice has been disabled due to software restrictions. If you look on the product page on the T-Mobile website, the specs listed have all 4 gsm radio frequencies as well as 2 aws 3g radios. The display pic even shows 4 full bars of cellular reception. The tech said voice was not supported at launch... however if the phone was "hacked" (his words) technically it could be used for voice and data. He also said that the data plan for the tab is the android smartphone plan, so if you do flash a new rom and have the unlimited plan... you should be gravy for voice and data!! I hope that all of this turns out to be true... we shall see in the next 2 days.
[Galaxy Tab General] hoolagen1:
thanks for the info, im already a tmobile customer and want to do the same thing, flash cyanogen to the tab. I have a nexus one and this would rule. my only other question is...can i use my full upgrade on the tablet? i spoke to a 2nd lev tech support and he said i might have a problem doing that because its tech. not a phone. the regular rep couldnt help me at all, she had no info until launch....didnt even know launch date. again can i use my tmobile upgrade for the tab....
[Galaxy Tab General] Alcibiade:
Sounds good :)
[Galaxy Tab General] shollywood:
IF this were true, and the hardware is all the same, then that would also lead us to believe that the EUR version should have 850 3G capabilities too then, should it not?

I find it hard to believe it is a software limitation. I HOPE it is but highly doubt it.....fingers crossed
[Galaxy Tab General] Step666:
No.

Rumours are that the T-Mobile US model uses a microSIM.

If that's true, then there must be some sort of difference in hardware between it and the EU models.
[Galaxy Tab General] foxmeister:
Not necessarily - the Telus Desire and "regular" Desire are essentially the same but have different radios to support different bands.

Regards,

Dave
[Galaxy Tab General] jdmadonna:
Just came back from demoing the Tab at my local tmobile store. It does use a standard sim. However the update is this: in the apps management screen, it seems that the only thing missing is the actual phone apk. The phone utility apk is there and the contacts apk is there. It looks like we just need the phone apk and then possibly the contacts merge apk to get voice enabled. Anyhow, the phone is being released at 11am pst tomorrow in my town, mine is on reserve so I will have it by 11:05am pst. anyone who wants to guide me into activating voice on this baby, send me a message and i will be happy to assist with trying some methods out.

I will need to try the following apk's from the euro version:

phone.apk

contactsmerge.apk

oh, the local reps looked on the computer and said that this device WILL require a webconnect data plan, not the unlimited android. There is a work around though... with voice enabled, you can call tmobile and ask for a tech support supervisor, open a trouble ticket and request an engineer to change your device ip range to that of a smartphone... then data and voice should work together. I had this problem on my aws version of the dell streak and it fixed it using unlimited voice and unlimited android data plans.
[Galaxy Tab General] shollywood:
So how are they 'essentially" the same then? Different radios means different hardware....

This is my point, the US versions are not going to contain the same hardware, hence it will not be a simple software fix. I HOPE I'm wrong, but I don't see it happening.
[Galaxy Tab General] Step666:
Because it's one tiny chip that's different, that's all.

The CPU, RAM, camera, display, OS, everything else is the same - hence essentially the same.

As foxmeister has pointed out, most of the hardware will be the same, so if it's as simple as just the 3G chip being different then it's possible that yes it may only require a simple software fix to enable voice calling.

The units don't to be 100% identical for it to just be a software matter.

However, until someone gives it a go there's no way of being sure.
[Galaxy Tab General] amdivoff:
the microsims are for iphone user that have unlocked their phones and port them over to t-mobile (makes it easier then cutting).

as for the plan. webconnect and regualr cellphone plans are two different animals... one customer having a mobile and a data stick will have two accounts. the webconnect plan is actually just data, no voice options. so really the only way for you to use this device as a phone is if you buy it full price and try your android device sim card on there. THEN theoretically it should work.
[Galaxy Tab General] Alcibiade:
Yes that's the plan. Paying the full price and if possible enable phone capabilities using a regular smartphone plan
[Galaxy Tab General] shollywood:
So why wouldn't ANYONE just flash the EUR firmware then and have everything enabled? You don't think they thought of that???
[Galaxy Tab General] Alcibiade:
I bet we'll know within a week whether it can make calls or not. And if I have to take a bet I'll say... it can
[Galaxy Tab General] shollywood:
I have never wanted to be more wrong on something...but I'll take that bet.
[Galaxy Tab General] shollywood:
Interesting logic....

So the Wave and the Galaxy S are "essentially" the same then....you cannot just throw Android on it and away you go...your logic would say otherwise.

The Wave too has the same CPU, RAM, Camera...etc. as the Galaxy S
[Galaxy Tab General] xexes:
Mine is onhold and waiting for me... I have a friend who knows Android tweaks inside and out ready to help me in the morning... hopefully we will know soon.
[Galaxy Tab General] Step666:
The same logic applies to locked and unlocked handsets, quite often it's just software 'so why wouldn't anyone just flash the generic firmware?'

It's a risk, that's why people don't do it.

However, in this case there may be something to be gained from taking that risk.

Unfortunately, we won't know for sure one way or the other until some intrepid soul takes that risk.

But the fact still remains, the vast majority of the hardware (ie basically everything but the radio) will be the same as the EU model and that means there is the possibility that all the T-Mobile US Tab (or perhaps an AT&T one) needs is a re-flash to activate calling.

At least I'm using some.

Now you're just being absurd.

The two situations are not comparable.

In the case of the Tab we're talking two versions of the same device just with different frequencies supported, both are still the Galaxy Tab, both are still the P1000, it is essentially the same device.

In the situation you have, for reasons unknown, chosen to highlight, they are two different handsets completely - they are different models, they have different model numbers, they just happen to have similar specs.

It would be like saying the Desire and the Trophy are the same just because they have the same CPU, RAM and camera and that you can just 'throw' the OS of one onto the other. It just doesn't work like that.

Or maybe you'd like to lend your expertise to the teams of people around here working tirelessly to port OSs between various handsets? Clearly they've missed a trick with this 'throwing' business you speak of(!)
[Galaxy Tab General] Alcibiade:
Not anyone flashes their phone, or overclock their CPU, etc, etc...

People here are a tiny minority. I doubt Sammy (or other phone makers) would care to make specific change son the hardware (=extra cost for them) in order to avoid a few people taking the risk to flash their phone (and void their guarantee). And again Samsung doesnt really care if you flash your phone, only the operators do...

On top of that lots of people will probably buy the tab on a plan (Or just the wifi tab) and will anyway be stuck for 2 years on a plan on which they anyway won''t be able to use voice. So anyway good operation for the operators who will have sold their 2 year plan (Then if someone is happy to flash the phone and go on another plan with their flashed phone... fair enough it's just extra money for the phone operator)

So... I think it won't be a different hardware because the upside vs the cost is probably not worth it

And I hope i am right
[Galaxy Tab General] mormegil83:
I really hope the T-Mobile version can allow voice calling. I went from DroidX to Epic 4g and am really beginning to miss that .3" on the screen and have been contemplating now whether or not to switch to the 5" streak but don't really wanna go back to ATT (had the original iPhone for years...) I would switch to TMo for the Tab if it can make voice calls, in a heartbeat!!! Anyone here see a problem with getting the Vibrant on Amazon for $.01 and selling it on ebay to put towards the Tab and using the Sim/ phone+data plan on the Tab?

Edit: Oh snap! now the vibrant is $99 on contract... the captivate is still $.01... Darn was kinda thinking of switching to the vibrant either way if it wasn't going to cost me anything...
[Galaxy Tab General] Paten:
What about the Wi-Fi only models? I wonder if they will be the same hardware with the 3g and phone capabilities turned off by software. I doubt it but I can still dream about it.
[Galaxy Tab General] foxmeister:
I would imagine at the very least that the WiFi only models don't have a SIM card slot, though of course it could just be hidden!

Regards,

Dave
[Galaxy Tab General] dliao:
Just got the T-mobile Tab. I haven't open it up yet, but I was messing with the demo unit with the sales, and we were making phone calls with the skype that was installed it. We managed to do the Skype-Out call from the demo unit (with the acct tmo_####) and was talking through the mic on the side of the Tab, and voice coming out from the bottom. So it does look like US version of Tab (at least t-mobile) has the necessary mic for voice ?
[Galaxy Tab General] Alcibiade:
Doesn't have the radio for 3G communication, forget about it
[Galaxy Tab General] LordLugard:
The Sprint version definitely does SMS. How do we know that? The 29.99 data plan option gives 1gb data and SMS. As for voice, no dice there.
[Galaxy Tab General] Shagman68:
Can you install Google Voice and use your Google phone number on it?

Sent from my Vibrant using the XDA app.
[Galaxy Tab General] tycon:
The contacts only register numbers as text. T-mobile includes unlimited text and mms. So installing google voice isn't working as there is no dialing sub system.
[Galaxy Tab General] shollywood:
It's not gonna work...sorry guys and gals!!!
[Galaxy Tab General] rpmbnsf:
...And you

know

this for a fact because....?
[Galaxy Tab General] Paten:
No, I don't think I will. Not until I see a teardown video that shows the radio isn't there. Until then, I will continue to dream.:p
[Galaxy Tab General] Jyveafk:
I'm rummaging around, finding tons of stuff listing GSM, there's phone settings, or rather it actually calls them Tablet settings, but the screen showing the phone number/connectivity is there.

It /looks/ like it's all there, just.... no phone app.

If it doesn't have the hardware, I'd have thought it'd be popping up error messages. That it CAN send/receive txt messages and has 3g shows it's got most of the hardware for connecting up and sending/receiving data.

I'm still thinking someone's going to get it working. If it means a flash of a euro rom, so be it, but I think it's some setting somewhere that's not been found. Flick the switch, load phone.apk, and we should be great.
