Good Day,
Let me start by saying that I had tried to post this under a thread in the development section, but was denied as I am a new member.
I require some advice regarding a bricked Samsung Galaxy Tab.
The unit will not boot or enter download mode, only the navigation icons at the base of the device light up and turn off when holding the power button for a short period of time. My PC chimes as though it can see the device, yet does not show up in "my computer".
Odin sees the device, but hangs during flash attempts at "SetupConnection".
After reading the thread regarding unbricking your Galaxy Tab, I was unable to determine the nature of this particular "bricking".
The device entered this state after I had attempted to flash the device with the new Gingerbread update which downloaded from SamFirmware.com. This was not my first flash on this device, as I had the new version of the Overcome ROM installed, and was attempting to bring the device back to stock firmware for my region.
Any help would be greatly appreciated.
Thanks.
Put the tab to the wall socket and charge it for a few hours. Shutdown your pc and unplug it. Once the tab has charged. Connect to the PC and attempt to flash a decent stock firmware like overcome's stock safe. Good luck.

Thank you for the quick reply,
I have had the tab charging via the wall charger for some time now. Will there be an indication as to when it would be advisable to try the flash ie: the device's current boot behavior will change...
And your instruction to shut down my PC and unplug it, unplug the PC?
Can you give me any indication as to what has happened here? For future knowledge... and will my inability to reach download mode restrict my success rate on resurrecting my BRAND NEW TAB ... LOL!!
Thank You DarkPal
Well your bootloaders arent screwed up as the tab is showing signs of life and is detectable in ODIN. Unless in a faaar fetched case of another hardware failure your tab firmware is corrupted. I asked you to unplug the PC to reset the USB host controllers (recommended in case there is a connectivity issue with usb).
Try to put the tab in download mode again after its been sufficiently charged and connect to pc then flash a decent stock firmware like overcome's stock safe.
Did the trick,
Thank you for this. Overcomes stock safe installed and running.
I do have an unrelated question when it comes to modem choice, and noticed that you authored the modem list in the dev section for these devices.
I am having some issue getting 3G connection, and cannot pinpoint if this is a firmware issue or modem issue.
I am in Canada on the Fido network, running GT-P1000
Can you suggest a modem?
Depends on what bands your network supports. I dont reside in Canada so I wouldnt know maybe someone else using fido can help? In most general terms the JPZ modem works for most GSM networks give it a shot first. If fido is an 850 band network consider JJ3 modem.
Thank you
I am very happy to post that I have resolved my issue regarding the lack of connectivity in my region.
It was in fact a modem issue.
I found the solution on this page
http://forum.xda-developers.com/showthread.php?t=847273
I followed the instructions on that thread to test the modem under the ROM prescribed there... it worked on all available bands in my region, and proceeded to use just the modem along with the overcome ROM, and again success.
I am attaching the modem for any other Canadian Fido users encountering this problem. Hope it I can pay it forward.
Thank you again for all you help.
Great support structure here at XDA!!
I had the same problem with only the navigation buttons flashing but i could still get it to connect as a composite device for heimdall after flashing stock safe I can get back to recovery but I get errors nd failures when I try to wipe data/cache its a Verizon grab seven inch black if that matters I got the files from stock safe all but a recovery file and I used my own modem and tried again with one of the stock safe modems is the modem my problem? When I reboot device I go into a boot loop where it says Samsung and it used to say Verizon instead can u help me please?
Which stock safe you are talking about.
I hope not GB stock safe v5 from overcome site. That is a gsm rom, not for cdma.

Yes..... i did.......um can u post a download link to the one I need plz? Like I said before I'm using a regular American Verizon version
Edit: OK I found a heimdall one click method that restored it but it restored it to a 2.2 I was on 2.3.5 and all this started trying to get to 4.0.3 so can I get ice or do I need to stay with gingerbread and if so how do I upgrade back to it if my tab is unlocked?
OK so I found a one click heimdall that restored it to a rooted unlocked 2.2 it was a 2.3.5 but this all started trying to get it to a 4.0.3 any suggestions on doing that?

It sounds like what they have is an sbf to stock 2.3.4. Several people asked how they could flash it without root. I'm going to assume their D3 did not ship with 2.3.4.

according to the posts, they're using Brush to get into the devices somehow? i've seen a few Chinese threads that use this method, but i've never seen it stateside. is anyone familiary with this process?

As far as I got it, this is a dev SBF, which means cannot be flashed on secured device.
Plus I am not 100% convinced XT883 and XT862 are identical hardware wise.. It will certainly help developers though as it may help them understand the structure of code groups/etc and may help them find a weakness that can be exploited to gain root.

From a quick google search, just replace "brush" with "flash" as they are flashing the ROM....using a recovery method (recommending wipe partitions, select .zip from sdcard, install, etc...).
I had read all the post in that chinese forum about droid 3 and I'm sure they do NOT have root
they said they can flash verzion machine using "SBF image", which should be leaked from china telecom(you can think as verzion in US), they use RSDLite to flash this, seems this kind of flash method doesn't required root.
and if you flash the "SBF image", it will get you a chinese version 2.3.3 modified by china telecom.
please let me know if you need more info from chinese forum

I commute between Shanghai and New York for work. I just ordered an XT883 unlocked to use on T-Mobile (USA).
Has this device been rooted yet?
Has anyone ported a good version of ICS or Jelly Bean.
With the 3 or 4 versions of this phone worldwide, it is hard to get a clear answer.
thanks.

I think it depends which XT883 ROM your device is running. From memory, some of the earlier versions could be easily rooted.
- Is the XT883 System ROM rootable?
"The SBF is rootable, the OTA update is not, but root can be achived via OTA rootkeeper" - The Solutor
More info: http://forum.xda-developers.com/showthread.php?t=1249720&page=13
There are a few versions of ICS around. None of them offer FULL working options, mainly due to the locked bootloader.
Motorola has recently announced that most of their 2011 phones will be getting official Jelly Bean.
Have to wait and see.
Hello everyone, after reading several posts in the forums I'm still very confused.
This is the problem I got a new Galaxy GT-i9000t that came with version 2.1 update 1 with no root access.
I followed a guide to get root access and then another one to fix the 3 bottoms combo.
Before continuing let me add some info about me and my carrier. I live in Panama and I use CLARO which uses 1900 band, I have chekced several CLARO users and it says 1900.
When I finished the above(rooting and fixing the 3 bottom combo) steps I still had internet from my data plan. But after following a guide like this one:
http://forum.xda-developers.com/showthread.php?t=1431596&page=2
I lost my ability to use my internet data plan , I can receive calls and make calls but I can’t surf the web .
I know my problem is the modem( that’s the only thing i have figure it out). Now my real question is what modem do I need to use. I’m looking at this post:
http://forum.xda-developers.com/showthread.php?t=876391
But don’t have a single idea of which one should I use. Also checking this guide in case I decide to flash the modem: http://www.darkyrom.com/community/i...nstalling-a-new-modem-gingerbread-froyo.1960/
This are my current settings :
Firmware 2.3.6
Baseband Version I9000xxjvu
Kernel Version 2.6.35.7-i9000xxjvu-cl851880 se.infraei-22 #2
Build number gingerbread.xxjvu
Am I missing something?

Your right, what a newbie I am in this things , I haven't updated the APN's. after doing it I got my internet back. But some how the "modem" I'm using is not so good.
You must check
Settings - Wireless - Mobile networks - Access Point Names
If blank: find settings at your carrier and add (menu - New apn)
If existing: tick to enable
Can also check your CSC: *#1234#
Alternatively:
MultiCSC OXA in your ROM is for Europe. Take a peek at samfirmware.com to find CSC for Panama, download and flash CSC using Odin/Heimdall.
Changing CSC WILL FACTORY RESET phone.
Smart to have backup of /efs (your IMEI) before flashing. Many guides to do this is available in XDA.

Hi, I posted about this on another thread, but was then told that there is a forum for the S3. I would like to root my S3 mini GT-18190N, running 4.1.2. Its still under guarantee so it needs to be able to unroot.
Somebody mentioned CydiaImpactor, as it would be the easiest. So I installed to my mac, ticked both usb debugging and accept unknown sources, and ran the program. Within seconds I got an error, 'Error signature bugs unavailable'.......which I posted to the thread, and heard nothing from there and still havent about what that meant. I eventually found out that it means the bug has been fixed. But that is all I got.
I just wondered, what does that mean, does it affect any other ways of rooting? I found another rooting program on here, was given the the stock firmware for my phone but that needs to be unlocked. I did ask about whether the same problem would affect that firmware, but no answer. It seems the advice given on the first thread I started, about taking this to the correct forums needs to be done, which is why I am asking here. Sorry for multiple posting its not spam, its on advice from members on here.
I am a complete novice, never rooted before. So could anybody show me a root system that works for my phone.
Thank you

hi bro, maybe i will buy this s3mini because i notice that it cost only 114.50 euro in my country, more than 50% less than the official price
so...
about root:
you can root the s3mini flashing the firmware with odin
else you can use cydia impactor(be sure to download the latest version from official websites)
i notice that samsung patched the masterkey bug exploited by cydiaimpactor in other galaxy phone but i dont know about s3mini 18190
however i rooted an s3mini of one of my friend s1 months ago, he has never made a firmware update and after he enabled debug usb and installed driver it work! and got root access on his phone, after root you CAN'T do ota update! you an use odin however maybe samsung upgrade to kitkat android 4.4
did you do some firmware update?
-Install TWRP (this video might be of help)
-enter recovery mode and reboot. TWRP will ask you whether you want to root or not
Hi, before I did anything I took a copy of the phone which I have stored on the laptop, windows 7. Then with CWM rooted the phone, and installed a ROM I found. The first time it didnt work, so I had to find another ROM, and install that. This ROM works but its not from my Carrier, which is EE/Orange. The Base version ends in AMJ2, which I dont seem to be able to find to get the correct ROM. The Build Number I have which is the ROM is DMod v6. It works, but its causing problems with Samsung. I have given hope of getting back to the original, but if I could get it to work with EE, it would be better. DModv6 is a US based ROM.
I hope I have explained it ok, its the first time I have done this, so not sure. Please ask for more details.
Sorry it took me so long to answer, have not been very well.
Thank you for your help

As I have already mentioned, its a US based ROM, which only recognises T-Mobile UK. My phone keeps loosing the connection all the time. and I have to reconnect. T-Mobile UK is the US version of T-Mobile even though we have T-Mobile in the country, but without the UK at the end of it. And believe me it is not working properly. The phone itself does work, its faster, the battery life is much longer than when it was on EE. But I am also now having problems with Samsung, they have stopped me from using their software, because they say my phone is not using the correct software.
My first try, I did get Kit Kat running, but without the CAMERA, it wouldnt work. But there again, it was on a US based ROM, and had problems keeping the connection going. That was awesome but without the Camera, it was a bit useless. If I could get a ROM thet had either EE or Orange,

Hey mate,
Try to use Maclaw's Recovery and KitKat ROM. They work perfectly! Flash Maclaw's recovery first (TWRP) and then wipe cache and dalvik and then flash the kitkat ROM (CM 11).
find them all here: maclaw.pl/downloads/ (stupid 10 post rule for new accounts doesn't let me post the link to HELP the user (johnmwc2)
---------- Post added at 06:32 PM ---------- Previous post was at 06:28 PM ----------
Also the reason that your phone has gone all crazy is because of the ROM you flashed (US version) probably only supports the US frequencies which is why you only get t-mobile network (in some places) as the frequencies change in each location as the phone masts give out different frequencies in different locations according to their surroundings (some frequencies penetrate walls much easier but may not go as far and vice versa).
Im 70% sure the ROM is the problem. the other 30% is me thinking maybe the ROM might not have anything to do with allowing the phone to receive phone signal ( in terms of SOFTWARE not hardware - before anyone tries flaming me). My other instinct tells me maybe its the baseband/modem version thats incompatible witht the US ROM?
just use Maclaws KitKat and TWRP!
They work a treat! :laugh:
Okay, I just got through doing this myself and it seemed that nowhere was this all said at once, or at all. So I thought I'd whip up a quick tutorial concerning how to Domestic Unlock the Samsung Galaxy S4 on any of the newer bootloaders/firmwares/modems. (Knox-enabled)
I did this on both a 4.4.1 galaxy and a 4.3 galaxy- one one NAE and one on MK2
First, for anything to work your modem must be an older one, like version MDL. Download the file SPH-L720_MDC_Modem.exe which is a one-click
Odin .exe that will flash ONLY your modem to MDL.
Steps- put into download mode by taking the battery out and putting it back in. Hold the volume down button, the home buttone and then press the power button. When it vibrates, let go. Press volume up.
Run the SPH-L720_MDC_Modem.exe odin one-click installer.
Connect the usb to computer from phone
when com[24] or whatever shows up, press start.
Now, for the domestic lock to work you first need to do the international unlock @ http://forum.xda-developers.com/showthread.php?t=2415587
It's real easy and explained well at the link above, but I'll run through it quickly anyways.
Download the s4unlocker installer from the post linked above.
Put your phone into diag mode by dialing ##3424#. Press Qualcom button and select the bottom selection.
connect (if it wasn't already) usb from phone to PC
You already installed the proper samsung drivers, right? If not, you'd better do that now.
Okay, now run the s4unlocker and press the scan and unlock button, then wait for the phone to reboot.
Now for the Domestic Unlock part.
Follow the directions at http://forum.xda-developers.com/showthread.php?t=2530610
I'll run through it real quick, too because there were a few things I wanted to mention.
dial *#0011# (or #*0011#, I can't remember)
when it comes up "No service", press the menu key on the bottom left of your phone. This brings up a menu (wow!), on which you should press "back"
Now press the menu key again and in the menu select "key input" A box will open up asking for you to type in something- enter a "1" and then press the enter key BEFORE hitting the OK button. Mine would not work unless I did this.
Now wait, sometimes it takes a good couple of seconds to give you the menu. Follow the rest of the directions from the above link, setting all the settings to what is stated. EXCEPT where he says to set all the preferences to WCDMA ALL, GSM ALL and LTE ALL. When I selected one, however, an asterisk appeared after my selection leading me to believe that you can only select one of these and so I set mine to GSM ALL and left the others alone. This worked for me, so I thought I'd mention it.
Now that you've manually rebooted after following the directions, you still have to edit your build prop to allow you to edit the apn settings. To edit your build.prop you must be rooted so root with CF auto-root http://autoroot.chainfire.eu/ download the proper one for the galaxy s4.
It's just an odin flash, so enter download mode
load up odin 3.x
hit the pda button and select the cf auto root tar
hit start.
After rooting I found that one time I had to do some of the service mode settings again and one time I did not, so I mention it here even though I think I had to because of some other error I had made at the time.
Go to play store and download build.prop editor and APN settings Shortcut
Load the build.prop editor and add these two lines to the end of the file
ril.sales_code=LOL
ro.csc.sales_code=LOL
Now reboot manually
add the apn settings widgit to the main screen and open it
click on menu and add an apn
Enter the apn settings for your carrier here. They're all different,(the carriers) but you can find them(the apn settings) easily with google, since they (carriers) all post their apn settings on their webpages.
Don't forget to save the apn settings.
Now select it.
Now reboot, since it couldn't hurt, right?
If you've done everything right you should now have an domestic and international unlocked Sprint galaxy s4. Enjoy.
I suppose you could now reflash the new modem back onto the phone, but I don't have firsthand knowledge whether this works or not- I've only read that others have said that it works. Remember, ONLY FLASH THE MODEM, the rest isn't necessary and will probably knox you all up
All I did was list these things- credit goes to all those who were linked in the above post. Thanks for all you do.
On stock 4.3 and higher you can go into settings and change your APN, so there's no reason to root and mess around with build.prop editor.
Every time i try this i cant get my wifi back up when i flash back to the nae modem. If i could get pass that then I'll definetly be do that.

I have read that the modem itself cannot be downgraded. You can run older android versions and such on the newer modems, but the modem itself cannot be rolled back. I believe it has been like that since MJA.
You can downgrade modem, but can not downgrade bootloader (aboot)

I completed both the international & domestic unlock. I believe I was successful in each. I have a T-Mo sim card inserted but am not getting a mobile data connection. I do have 2 bars of service though. So I have gotten past the red X on the bars.
I am on 4.4.2 with the MDC modem. I did not do the build.prop stuff, instead opted to just access the APN's from the default menu.
A few things in my menu were different than the OP (probably because of 4.4) such as:
I dont have any roaming menu options
I dont have WCDMA.. just CDMA and LTE/CDMA. I currently have it set to LTE/CDMA
In my APN edit info there was not a place to put in MMS protocol: WAP 2.0
Also under About Device "my phone number" is wrong.
Am I missing something to get this t-mo working?

You didn't unlock it. If you were on NAE modem while unlocking then you failed miserably because you're not able to get into the most important part of the unlock...The service menu. If you did indeed downgrade the modem then you're going to need to follow the domestic unlock guide again. If it's showing CDMA/LTE you didn't do it right. It should show WCDMA only and WCDMA only isn't an option you can just select. It gets put there by the service menu.

I said I wasn't on NAE, I am on MDC. I did get into the service menu. I did everything in the process without issues. My service menu did NOT have a WCDMA only option. It had LTE/WCDMA and that's what i chose. I just went to the t-mobile store and they verified my APN settings were correct. I am unsure of what to do at this point other than just start all over and do it again.
Anyone else?

I apologize. Long work day. Follow the guide. When it comes to where it says select LTE, GSM, and WCDMA all, ONLY select WCDMA all. At no point should you see your Sprint phone number in about phone. Also you should see IMEISV in about phone as well if you've successfully unlocked it. It'll help if you posted the steps you've gone through. Otherwise were just shooting in the dark.

Imeisv visible, definitely unlocked as i can make calls texts and use edge data on redpocket mobile (att mvno)
But in phone number I still see my sprint number and I can't get hspa (picking the wcdma all gives me red x no bars, picking gsm all gives me full bars and edge data)

From the S5 thread and now here we meet again in a revisit in time. Since I know you own and understand the L720 more than I do, could you please explain to me if this will work on a 4.4.2 NAE rom? I picked up an L720 (bad esn) for $100 and its in pretty great shape. Now I'm looking to unlock it but my experience with Samsung devices are very mild. It came on CM10.2 (4.3.1) and ive slowly caught up with things. So i understand that sadly there is no such thing as downgrading from KK to JB, I was trying to get it stock on JB with no cigar. Elsewhere I found out that you must flash something identical or above. So im planning on flashing an NAE 4.4.2 stock rom (custom recovery flashable) I found in order to attempt to unlock it cause I can't seem to find a 4.4.1 as mentioned in the OP. I flashed the MDC modem and it stuck, so with little knowledge I am assuming that it will stick once I flash this new rom? Correct me if I am going down the wrong path...
EDIT: Great nobody ever mentioned anywhere that the software used on the international unlock is for 64bit only...

The software works on 32 bit too. Actually you can even perform the international unlock WITHOUT the tool if you know how to use QPST or DFS. Anyway...
Flash full NAE. Flash MDC modem. International unlock. Domestic unlock. Win.

Must be an issue with my PC, nothing new...
And I know a thing or two about QPST. I still have it on my computer from a few days ago from when I was fixing a horribly corrupted IMEI on a G2 a friend of mine bought. I'm assuming I have to use a NAE stock tar with ODIN, because I tried a ROM of it and it lags and stays on black screens for seconds and WiFi doesn't work im sure because of the fact that the modem is older than the rom. Let's see if that works cause ive been trying to flash back to any stock ROM since I got this thing yesterday.
(Almost there...)
NEVER MIND. Got the international part working perfectly by using the Windows Vista partition on my PC. Now reading on, OP mentions that next the domestic unlock must be done, a link is provided there to another thread with domestic unlock instructions. Heres the question. The OP in the other thread mentions to hop onto 4.3 via odin. How can I get to 4.3 to domestic unlock if Odin doesnt let you downgrade?

Read the specifics. You cannot downgrade boot loaders but you CAN downgrade modems.
Unlock just requires MDC or MDL modem.

Yeah I remember that part but from what I was understanding, that's for the international. Domestic requires messing with some files and done. I already got the international part by tossing CM10.2 along with the MDC modem because stock Touch wiz would cause lag and reboots and non working wifi I'm assuming because of the mismatched combo. I DO know that obviously we need a TW rom in order to unlock domestic.
EDIT: I finally got the hint and got it to work. But I only get Edge instead of 3G. Does anyone know where I may be able to find that T-Mobile rom made for us? When I Google it I end up on the T-Mobile side.

I downgraded from latest bootloader on 4.4.2 or was it 4.4.4? Down to 4.3 which is the absolute best ROM version for service mode menu. It got me into service mode menu on first try by selecting menu back and input of 1. What I did was first install cf autoroot to root then cwm and used cwm to flash the 4.3 stock deodexed, I only used Odin for flashing modem. Odin gave me an error when flashing modem and phone got stuck in kies mode but i got it to get unstuck by just flashing cf auto root again to make the kies mode error thingy think odin flash has went well. Turns out MDC modem flashed despite odin error.
Anyways. While on 4.3 and MDC modem I noticed no WiFi but I had sound. I followed the international and domestic unlock instructions and WiFi was still broke when I got back to 4.4.2 but I had unlock and sim card working and got bars. I am on aosp 4.4.4 now and the nae modem I finally flashed works well with this ROM but soon I gotta go to touchwhiz 4.4.4. If I go to 4.4.4 touch whiz WiFi and all else will work fine just as they do on slim aosp . 4.4.2 touchwhiz is still not giving me wifi on NAE modem. Update NAE 4.4.2 stock deodexed rooted rom i got from xda android thread did the trick and all works well now. All is perfectly working after i flashed it in cwm.
For aosp lovers. aosp requires additional things to do so aosp dialer can make and receive calls fine. I can call but there are issues until I follow another guide on xda that resolves those issues on aosp ROMs using sprint s4.

If you see system slow, no wifi, no audio and lockscreen being nearly impossible to unlock, its due to you being on a higher ROM than the modem was meant for.
