[Q] Going flash happy on the SGT - Galaxy Tab Q&A, Help & Troubleshooting

Just got my Tmobile SGT last week and wanted to make it different from all my friends that had one. For the moment it was the talk of the crowd when it was running Gingerbread and unlocked to the network and running a bunch of nonsense/useless apps that made people laugh for hours. Well, somehow I ended up bored and ended up flashing it back to stock tmobile. Well, now it does not connect to the carrier and the power button just restarts the whole damn thing. And also it will not go into recovery nor download mode either. Can anyone guide me in the right direction to make it work like how it did before I owned it??? Thanks.

Strange if your tab boots into gui but you cannot go into recovery or dl mode.......

Today again I started tinkering with it and got it back running correctly. I ended up rooting it with z4root then put CWM Recovery to gain back the ability to get into recovery and dl mode. Yay! And so.... I ended up flashing it again, but this time used Overcome-Gingerbread and followed the directions CAREFULLY. Everything turned out just fine and dandy except I still cant connect to the service carrier. I think this happened when I removed the sim network lock thing. Any advice pls?

did you flash the correct modem?

Yup, I used the TMobile US one.

Okay I think I might be wording this wrong...
Noticed in the status screen it shows "T-Mobile" under Network and "In Service" under Service State. Meaning I am connecting to my carrier, correct??? And also TMobile shows up on the top right corner when on the lock screen.
But when I try to browse the Internet it returns with pop up "No network connection Unable to load page. Internet not connected."

Mmmm your APN settings are correct?

Yep! Even try a few different ones also.

In light of this, I would be pointing fingers at the apn settings, that and silly but check to make sure data is turned on in the settings.
Other than that I'm out of ideas

i believe u must flash your old stock rom CSC or replace it via root explorer .. after u did that ... fire up the dialer .. write *#272*IMEI# then choose your country code
or if you are in euro just forget all this steps and do only the *#272*IMEI# STEP and you'll get your 3g up and work

i think i broke my phone :( help needed

hi all
i thought i would attempt to flash my samsung s with the new beta froyo update.
i followed this guys tutorial.
( cant link to it sorry its the noobs guide with detailed instructions through kies and odin)
i used the odin approach
i managed to root the phone.
on reboot it asked for an unlock code (o2 uk) so i went on to try and follow the steps about unlocking it. which neither worked all the way through the steps.
on reboot it appears to have signal and in the about section it says i am onnected to the o2 network but when i try to make a call is says "data network not available with an ok button, which when pressed will return you to the ome screen.
any help would be greatly appreciated thanks
Almost the same problem,
installed 2.2 update successfully, the phone worked for like 3-4 days very well and after that today i discovered "Emergency calls only"
so the question now is did i bought phone which later was reported stolen? or somehow i broke it?
Anyone have any idea?
hmmm, I have the same problem! In the status menu, the number is shown, but the network, says "unknown"
Hi! I have this exact same problem except I was unlocking my phone using this tutorial:
http://forum.xda-developers.com/showthread.php?t=906255
But I didn't back up my Efs folder, now my phone is unlocked but when I put a sim card in it I have very little network and when I try to make a call I get " NO DATA NETWORK AVAILABLE".
I've tried everything but I don't know what to do!
I was thinking of two ways to fix it:
1. Reinstall froyo (not quite sure how using the samsung software as my laptop oesn't recognised the phone as a pone)
2. Downgrade to, get unlock code using market app and then upgrade to froyo again.
I know I messed up but now I really need to fix this.
Can someone PLEASE PLEASE help me out.

might need to change the modem in odin i think. just heard about it
did u try restarting the phone... just a wild guess...
I had the same issue before and was puzzled. Its actually a very simple solution:
1. Re-lock your phone, search through xda there is a code you have to enter
2. Unlock your phone
All done! Surprisingly easy
Try the Odin method in block 2 back to Eclair if ok then upgrade to Froyo .
http://forum.xda-developers.com/showthread.php?t=818556
However your non connection might be due to not flashing a firmware with your network settings in which case manual settings of APN .
If your IMEI has changed due to flashing and you did not back up your EFS folder then little hope but do a google / search of XDA as some have reported success .

Emergency calls only
I had a custom rom that was giving that to me too. I think it means that you can access a network different from your sim (because usually emerg calls can be made from any phone I think?).
I'd try and find a rom that is optimized for your carrier or at least a modem file from a stock rom that is for your carrier. You may also need to reselect the APN settings (or enter them for your carrier). Its under settings/wireless and network/Mobile networks/access point names (use the menu button to add an APN).
you could also try re downloading and flashing the rom to make sure that is the issue. Mine said it installed OK but never booted up, redownloaded and reflashed and then it was fine but the install screens looked identical.

Hi! Thank you so much for everyone's replies!
My IMEI isn't changed and someone helped me check my efs files and they are all ok. I'm going to try and reflash froyo through the samsung software to see if the network lock comes back and then try to unlock again. For this I'm going to unroot the phone and follow samsungs' instructions.
I'm afraid to relock the phone as there are reports that say it completely messes everything up!
But I'll keep you guys posted! Wish me luck!!!!
PS. Any other suggestions are more than welcome!
So, a quick update on my situation.
I uninstalled busybox and unrooted my phone using the oneclick root tool.
Did a factory format and, surprise surprise, my phone now works perfectly!
Apart from the fact that it doesn't connect to kies, but that's a whole another issue!
Tank you so much to all of you who answered my cry for help!

gingerbread att tab

Just flashed the new gingerbread rom. Works great but it doenst recognize my sim card or network. I have att tab. Any help to restore it?
Did you remember to download the Modem package too? That's what I'm guessing.
sent from my Galaxy Tab using Cerebral up-link
Did you flash the version with the bootloader? Any whiteline issue on boot?
No I didn't download or flash a modem do I need to? I flashed the one with the bootloader. No whiteline I noticed.
I flashed with bootloader, tried 2 different modems, and no network. wifi works. tried flashing back to stock and everything went crazy. While I was using Odin, I STUPIDLY, plugged in my Captivate to charge without thinking, causing Odin to fail and I got the "phone - ! - PC" Icon.......talked about scared! Ended up using Roto's ATT stock image and Odin to get it back running again,barely. Now I get CRAZY lines when I boot (like if you tweaked the cable to an LCD screen), can't see Recovery screen....total craziness. Still no data. so I flashed back to OverCome Gingerbread ROM following his instructions, still no data
UNTIL
I swapped the SIM card with my phone. I suddenly got data on my Tab, but data would not function on my phone. Seems like the problem follows my SIM. Background: I also had a weird issue before hand where I couldn't open the Market on Cellular data without killing the data connection on Stock Rooted.
Thought I'd share.
EDIT: oh, and I can send text messages without issue.
Go to Settings, Wireless & Network, Mobile Networks, Access Point names and make sure you have one called Broadband (assuming you are on the ATT monthly data only plan)
If you dont, create a new APN and name it Broadband & make the APN Broadband as well. Just leave the other options and save it & select it.
I think by default it comes up with the ATT wap.cingular APN with doesnt work with the Tab Data plan.

Gingerbread 2.3.3 installed modem does not work
AT&T monthly pay as you go. What modem.bin do I load? Where can I get it. Is there any additional setup instructions?
Follow my instructions above and flash the JK3 modem fromt this thread.
http://forum.xda-developers.com/showthread.php?t=1069727
Mine keeps saying insert sim card to access. So how do I get it to recognize the sim?
Please anyone with some help? Can I store back to original att froyo and just wait for official upgrade?
Have you guys entered in your APN settings for ATT Broadband?
I am also having a strange radio issue. I am using an ATT Tab with Overcome v2.0 Beta 2 and the JK3 modem. 3G data works great until I try to access the Google Android Market. As soon as I do it drops the 3G connection and wont come back until I reboot it. If I dont go to the market or only go to the market on WiFi it works just fine. I also verified that the same behavior happens with the JPZ modem..
My theory is somehow ATT is blocking Gingerbread Tabs from going to the market using their SIM card. Therefore I think maybe I need to edit my build.prop to spoof them. Can anyone recommend which values should be changed? Can anyone think of anything else that could cause this? Can anyone reproduce this issue on their ATT tab?

You used the bootloader patch app, right?
Reinstall the stock 2.3, then the root, then overcome. Follow the overcome guide, this time put the modem.bin in the phone slot in odin. There is no other fox for the wiggly lines. If you don't reflash everything, you can't get into recovery mode.
i cant get into the network settings as it tells me to insert a sim. I tried to flash the modem as well with no luck.
ok so I turned on my tab to play with it a bit and I had data! It was an H and seemed to work. When I restarted the tab it stopped working and said no sim again.
1) The Gingerbread rom has a modem with it that works fine on AT&T.
2) Did you leave your sim card in while flashing?
i did leave my sim in while flashing. Should I have it out? It seems the tab only recognizes the sim card every so often. Not all the time. Any way to flash the sim recognition part?
Could you please post how you flashed your att tab so I can follow it? Thanks.

[Q] Unlock and Radio Issue, Please Help

I am deployed to Afghanistan right now. I ordered a brand new XT862, rooted it, and installed safestrap 2.10 and cm-9-20120815-UNOFFICIAL-solana.zip. That worked beautifully.
Unfortunately I am having problems getting the radio to work. I would set an APN but then sometimes it would just not appear in the list. I would set it again and again, then sometimes all of the APNs would appear in my list until the radio failed. After flashing, formatting, and reflashing several times and having the default Verizion access points finally pop up out of nowhere in my APN list, I realized I never "unlocked" the phone. I am using a Roshan SIM.
The weird part is the radio would work for a period of time. First for several hours, then it would start failing more and more frequently.
I found the XT862-5.7.906-SAFE and flashed it, hoping it would ask me for an unlock code upon booting, but no dice. It just went into "Global" mode. I am testing right now to see if the radio stays stable.
So, I am wondering if these instructions:
Guide - Unlock XT862 for T-mobile/ATT
http://forum.xda-developers.com/showthread.php?t=1406812
will get me to the unlock code screen, and once unlocked, will my radio problem disappear when I reflash CM9? My Internet connection is painfully slow here in Afghanistan so I only want to download what I know will work.
I do have a second XT862 that I had unlocked, then rooted and flashed CM9 to and it is working very well on Roshan out here.
Thanks for your help!
While running the XT862-5.7.906-SAFE, the radio cut out and I got a BP paniced message. I couldn't remember all of it before it crashed completely, but it asked to connect the USB for debugging. While the screen was flickering, a window popped up asking if I wanted to switch to GSM.
The radio doesn't seem to be stable even with this firmware.
Any suggestions or help would be greatly appreciated.
The radio cut out again, so I tried switching it from global to CDMA and then to GSM to see if I could get it to reset.
It told me there were no GSM networks available, and then asked to switch to Global.
I hit ok, then it told me that the SIM was invalid...
I'm a noob to this phone stuff, but this just seems crazy.
It seems it's definately the phone, because I swapped the SIMs in my two phones and the problems persist with the new one. My functioning phone continues to work fine on the chip designated for the problem phone.

No, I haven't yet because I didn't know if that was going to solve my problem or not. Downloading is a challenge for me right now, too.
I don't know if not unlocking the phone before flashing CM9 caused the problem or if it's something else entirely that I am missing. I will want to have the phone usable in the states again. Will flashing the 883 radio give me any difficulties there?
I've went back though the steps that I did on my other, working phone and [edit] not unlocking is [/edit] pretty much the only difference.
I'm probably going to try to download the 883 radio stuff tonight when I get home from work and give it a try.

Unlocking the phone MUST be done on stock firmware. The XT883 radio is only required for using US GSM networks, such as AT&T and T-Mobile. The stock XT862 radio (after unlock) supports foreign SIM cards (and of course Verizon's Vodafone SIM).
As I recall, CM9/10 normally has issues with the GSM radio, if you need your phone, I suggest flashing a ROM based on a stock GB system, such as Maverick (4.0 version, 4.5 has a battery drain issue with an overclock script) which is based on 906. I tend to keep the phone on GSM/UMTS mode, as "Global" also turns on the CDMA radio, which utilizes more battery. The APN only matters for Data/MMS without the proper APN, you should still get talk/text/signal (no EDGE or 3G icons, which indicate data connection).

I didn't update the radio on my working phone to 883. It has been doing just fine on Roshan Afghanistan and AIS in Thailand. In the states I use Verizon, so I don't think GSM is a biggie.
So, I have to get back to stock and unlock, then go through the hack process again. I figured I probably did. So before I try to download this file, do you think the 1-click SBF here:
[xt862] .906 1-click-sbf.exe + tools [10-8-2012]
http://forum.xda-developers.com/showthread.php?t=1686911
will do the job? If not, do you know what will? I'm still running XT862-5.7.906-SAFE. I do have Blur_Version.5.6.890.XT862.Verizon.en.US.zip but I don't know how to install it. I'm still learning all of this stuff. Would RSDLite do it?
I wasn't very specific when I talked about the radio, sorry. More or less the voice connection would stop along with the data. It was just weird that sometimes the APNs would show up in the list and sometimes they wouldn't. When they did, it showed multiple from when I tried entering them several times. I don't know why it would write the changes but not read the list.
When about five Verizon APNs showed up and none of my Afghan APNs showed up, I realized I must have needed to unlock the phone. When I hacked it I just assumed it wouldn't have to be unlocked. I figured I WAS unlocking it. LOL!
Thanks everyone for your help.

If you were on the 906 OTA, the one click EXE would work, no programs required. Connect phone in bootloader > run the exe > The phone will flash. In Global mode, when you check the APNs, only the Verizon ones will show, you MUST be in GSM/UMTS mode for your own APNs to show up. Also, if it's occasionally in and out, I wonder if the connection between the SIM and phone are bad, like a shake or movement will break the contact. (Which when a SIM is not present, only the Verizon APNs will show as well and would prompt for global mode)
Try taking the SIM out, cleaning the contacts, and placing it back in. If the sim seems loose, try slipping a single thin piece of paper behind it to make sure it's getting full contact. Otherwise, it might be a hardware fault.

XT862 5.7.906 Update FXZ DST
http://forum.xda-developers.com/showthread.php?t=1554916
It doesn't say that it's an OTA. I'm still running safestrap 2.10 with it. That's why I was curious if that might work. I also have that full BLUR download already. I tried installing it using safestrap, but that didn't work. I'm assuming because it's not supposed to. If I can get that installed and it works I'd be happy. I have to remote into my server at home, download there, and then FTP over here at like 6k/sec. Am I correct in assuming I'd install that full BLUR image with RSDLite?
I haven't had any issues with the SIM from the bad phone in my good phone, and everything feels tight when I put the SIM in. I've tried cleaning the contacts a bit. I haven't tried putting something in there to hold it tighter yet, though.

The Droid 3 does not require RSDLite, as it has fastboot. Which is able to flash certain parts alone instead of the whole system (or the whole thing together) it's easier than RSDLite and can make modifications without losing everything. That's how the XT883 radio is flashed without modifying the system.
The one click method would fully flash it as if you used an SBF in RSDLite. If you have safestrap enabled on safe; make a full backup with recovery, then disable safe-mode. You'll then reboot into your stock system, unlock there, then enable the safe boot again, restore your backup.
SIM unlocking is for good, no amount of flashing, updating, etc will revert it. If the phone DOES get service with the sim, then it's already unlocked.. if it's occasionally cutting out, that's a different issue.

Holy shinto! I didn't know it saved that! I figured it was gone!
So I disabled safestrap, then it kept telling me com.android.phone had stopped. I'd force close and it would say it again. I went back into safestrap, did a factory wipe, rebooted and now it is connected in "Global" mode again on the stock 5.6.890.XT862.Verizon.en.US. It was looking good for a while, until the phone just rebooted itself.
I put my other SIM in the phone, booted back up and it worked for a while until the signal dropped and the phone gave me an invalid SIM error again. So, it's given me an invalid SIM on two different SIMs now in stock and flashed ROMs.
The SIM is in there tight. I couldn't get a piece of paper in there. I cleaned the contacts again, but they don't look dirty at all.
I put the original SIM back in there, it booted up, never got signal, and rebooted itself again. It doesn't have signal now, and I assume it's just about to reboot itself again.
You think I got a bum phone? I didn't test it at all before I started hacking it.
Also, if I do the *#*#4636#*#* while it has no signal it tells me my IMEI number is unknown, if that helps. If press the turn off radio button, it does nothing.
[edit]It also tells me pretty much everything (MEID, IMEI SV, SIM ID, ect...) is unknown if I go into About Phone>Status[/edit]

That happens if either; Airplane mode is on, or you have an incorrect build.prop, have you modified it in any way? Also have you tried making a backup and turning safe boot off?
Also; If the zips are still on your SDCard, try reflashing your rom to make sure you have the correct build.prop.

I have safestrap turned off and it appears I am running on stock? It says I am running 5.7.890 and not 5.7.906. There is a Superuser icon in the all apps, but I think that is from where I rooted it.
I rebooted and all the numbers came back... for now.
I don't have airplane mode on. I tried to turn it on after reading your post. It caused the phone to reboot. Once rebooted, it came back up in airplane mode. I turned it off and it is connected again, for now.
I haven't messed with the build.prop that I know of. I only rooted, installed CM9 several times, formatted everything several times in-between those installs, and most recently flashed that XT862-5.7.906-SAFE.zip.
And before I even finished this post it rebooted itself on me again...

And before I even finished this post it rebooted itself on me again...

Alright, did you put the sim in and get the unlock screen to put in the unlock code? 890 is alright to be on, that's what my stock system is. I would suggest staying away from CM9/CM10 as they are unstable when using GSM networks. Either stay stock or flash a ROM based on Blur (I suggest MavRom 4.0).

It never asked me for an unlock. It just immediately put the phone in world mode.
I literally did this with the phone.
1. open factory sealed box
2. root the phone
3. install safestrap
4. format all partitions
5. install CM9
6. install SIM
7. repeat 4 and 5 serveral times
8. install 5.7.906 hoping to get an unlock screen in order to possibly fix radio issue
9. start this thread.
Now, I did steps 4 and 5 over and over again over about 2 weeks off and on while I tried to figure out what was going wrong. Like I said, I am running CM9 very successfully here since August on a different XT862 that I did unlock before rooting. I installed a KANG build, not a KEXEC.
The amount of times your device seems to be rebooting makes me think there is something wrong with it.

Hm... while in unsafe (stock) the unlock screen should have come up. It will not on other roms, as for global mode, that is a default setting, without unlock, will only work with the verizon vodafone sim that came with the phone. Reboots can be either hardware, rom, or app problem. You can try a factory wipe and see if that helps the reboots. Trying to find solutions without you having to download more.

I was kind of worried that was the case. I just ordered a refurb unit just in case.

[Q] many problems now no network

I have a p925g rogers canada. It had a problem while updating and was bricked, no lg logo, no vibrate, nothing.
I managed to revive it a month later using Smartflashtool and lgp925_ap.bin and lgp925_CP.fls and that got me the logo back but the phone would reboot in less than one second of logo appearing.
So I then used LG mobile support tool and did a recovery, it recognized the imei in download mode and now the phone is up and running on 4.0.4. with baseband omap4430/xmm6260 and build number is ICS and software version is p925g30c
This phone is unlocked. I put in a koodo sim card and no luck. I get "No service"
Under phone identity i get the imei, the imei sv, they are all there but my phone number is "unknown" and I can never connect to the mobile network.
I've read many threads on here, about 12 hours now, and I'm seeing "flash baseband" etc. I dont even know how to do that with an LG. I've done many sammy's and used odin and cwm/twrp so I do have some experience with the process.
I'd appreciate any help with this. Please don't point me to a tread that just says "flash a new baseband" I don't know how lol.
sorry in advance.
Did you set up your APN? How to do that and how to flash

would you believe that I re-did all the apn and after about an hour, it started working,
Couldn't have done it without XDA
PS I hate cellphones.
Which is why I love them.
lol
Hmm sometimes rebooting a few times after an update helps things work better. Well, good it works.
still wont do messaging, and drops the network alot, also getting "Reorganizing internal processes" when I try to call but it goes thru after a few tries. I may try a custom rom if I can ever get into recovery mode (it wont let me)
correction, mms is working sometimes just like calls. Factory reset a few times. no difference.
edit - no data whatsoever. All apn setting correct, all settings rechecked. network unavailable.
no IMEI & no SIGNAL (network)
Could someone help me?
I flashed my LG THRILL 4G (AT&T) with official stock P925 V30B rom (with SMARTFLASH) but lost the IMEI and no NETWORK. :crying:
What can I do now?
Thanks!!
Use Flash Tool. See link above.

No network connection stuck in airplane mode

I have a Note 8 N950U that was originally on ATT. It was bootlooping and I got it to work somewhat by flashing the ATT_N950USQS4CRE1_ODIN firmware using the moded odin file. The phone will boot and all seems to work but it will not work on a cellular network. It shows the "no network connection" error and the airplane mode switch is highlighted as if its on but it is not on. I've tried resetting the network settings, reboot with airplane mode on, etc. I also have tried several different working sim cards and all do the same. The phone does recognize the sim because it sees my phone number in the settings.
I recently reflashed the device using the N950USQS5CRG9 firmware, and still have the same issue. the device boots and all seems to work except the cellular network. I also tried different APN settings as well.
I seem to be having trouble with other firmwares because odin will just error out on me. These are the only 2 firmwares that I was able to get to flash. So is this a firmware issue or a hardware issue? I would really like to get this device to work if at all possible. So, any and all help is greatly appreciated.
TIA to all!!!

What version of the bootloader are you currently on now? And did you flash a CSC file from AT&T and then do a factory reset in recovery mode?

I am currently on N950USQS5CRG9 bootloader. And yes, i flashed this CSC file, CSC_OYN_N950UOYN5CRG9_CL13949550_QB19107689_REV00_user_low_ship_MULTI_CERT, which I believe is an ATT file. I did not do a factory reset in recovery mode after the firmware flashing. The device was factory restored prior to flashing though. THanks for the help, I've been messing with this for a week now...Thanks again.

Try going from CRG9 to N950USQU5CRIA because that could fix the problems.. Download the update.zip from the website put it on your SD card and then boot into recovery mode and select flash update from SD card and let it do its thing after you select the update file.. You have CRG9 still and you'll be able to flash back to it too if you have to for some reason.. The website is here put your model of phone in from the dropdown menu(Note 8) and then the next dropdown menu select your CRG9 firmware and it will give you some updates but take the latest version that's N950USQU5CRIA not the old ones after it flashes try a factory reset again!!

OK, went through and did exactly what you said do...the update went through and finished, the phone rebooted, and then I restarted phone and did factory reset, and I went thru the setup and the update did take, but still same issue. Tried 2 different sim cards that work in other devices and still no network connection and airplane mode is still highlighted as if its on. No signal bars just a 0 with a / slash through it.
Any other ideas? Really do appreciate the help. TIA!!

Try this.. From the home screen, tap the settings icon, scroll down until you see General and select it, scroll down until you see the reset option. Select reset. You will be taken to the reset screen. Select Reset Network Settings, if your phone is password protected, enter your code. You will be taken to a new screen confirming your selection.
And the last idea I have is that you have a hardware issue if the above didn't work and there's something broken internally and you need to go to AT&T immediately and have them either replace that phone or call Samsung because there is a 1 year warranty on the phone for free from Samsung and they'll fix it and return it so long as it's not from something you caused, like water or dropping it and breaking it.. Also, where did you get that phone from? Is the IMEI clear?

That's one of the 1st thing i've tried before anything else. It says it resets successfully, but does not fix issue.
Unfortunately, I got this second hand...It worked great until it started boot looping, so returning it, isn't an option. I guess the baseband chip
got messed up some how. Anyways, thanks a million for the help...it was much appreciated.
