[Q] Reversing Gingerbread Baseband Flash or Correct Baseband for my Provider

Good Morning,
After flashing the Gingerbread Baseband I no longer am able to register on the network for my provider.
The device is from Rogers but unlocked and being used on the Bell network.
After flashing I realized there may be a different baseband for me to use in Canada (just North of Toronto).
I require some help in locating a Gingerbread baseband that would work or provide me with instructions on how to return to the original baseband.
Any help is appreciated!
Thank you kindly,
- Audi2Audi

Did you set the APN manually? You have to do that.

Hello!
APN in Menu|Settings|Wireless & Networks|Mobile Networks|Access Point Names ?
I have set that to: pda.bell.ca
Is there other steps required though?
Thank you for the response!

apn settings is for internet. phone must tower of sim. may be flashing baseband again will soveit because i am tower getting for my country

If you're wanting to go back to stock froyo first you need to visit here to get your original rom... these will also flash the baseband back too
http://forum.xda-developers.com/showthread.php?t=1246678
or here http://forum.xda-developers.com/showthread.php?t=1155874
then you will need to follow this turtorial in order to flash the stock rom back on (go down to second post that one is in English )
http://forum.xda-developers.com/showthread.php?t=1244490
Although it is a possibility that the BB hasn't flashed correctly, might be worth trying it again... might also be worth trying a froyo rom to see if you get a signal then, because if you do you still have the froyo baseband on...

Thanks adixtra i always forget about the tutorial of yours

You can flash a .Bin File for Your P920 or P920H.

Ok, now this is getting bizarre hah.
I reflashed the baseband again and everything went normal as it did before.
This time I searched for networks and selected my provider. After about 5 minutes of the device trying to register on the network an error was received that said it was unable to register on this network.
However, when I got to my home screen I was registered on the network. I tested a voice call and it worked. I have tested data as well.
BUT! This is where it gets even more bizarre...The device cycles from 4 signal bars to 2 signal bars to none to 3G (from H) followed by not being registered on the network. Then a few minutes later (sometimes only after a reboot) it returns to 4 bars and begins the cycle again.
Has anyone seen anything like this before?
Thank you again for your help!

Good Evening,
Would you be able to upload the KDZ file from your update?
I am having problems with the LG Phone Recovery indicating that I have the most up to date software and halting the recovery process.
Thank you!
- Audi2Audi

Hello,
I flashed an earlier KDZ which allowed me to use the LG Update tool to restore my stock rom.
Thank you everyone for your help and advice.
- Audi2Audi.

it will tell you that but if you use recovery mode and it will download the file then you will have to unplug the phone from usb hold vol+ power then plug it back into the usb and it should download. like i said i used similiar method to flashing baseband

On my windows 7 not detect omap 4 and i can't flash baseband,what can i do?

[Q] No Sim card shows phone number

With sim card, phone activates with correct phone number but Network shows Unknown and can not use verizon network. With no sim card phone number shows 000-000-9xxx. I am not showing the last 3 digits on purpose. My wife's phone does not show a phone number with no sim card.
I reloaded factory image and did factory update via wifi and still have the problem.
Problem started when I loaded an updated custom binary. I have been using custom binaries for three months with out issue.
I have done a complete wipe. Is there an area of the phone the still needs to be wiped?

You most likely lost you imei/min or something, you can check in settings>about phone>status. Easy way to correct it is to flash a older stock ICS image and use the reprovision code. Flash this in odin then type this in the dialer *2767*3855# and that should fix ya back up. Flashing anything carries a risk of dropping your imei but it happens much more on AOSP roms.

dialing *2767*3855#
auto message from this call just says your are being transferred to an external operator.

[Q] Reverse Flashed Galaxy S3 from Cricket back to Verizon

I made the mistake of not meeting at the Verizon store and bought a Galaxy S3 off Craigslist. It has a clean esn but it won't read the 4G sim card. I found out it was flashed to Cricket so I used Odin to flash it back to the original rom that came with the version of the phone which changed it to Baseband version: I535VRLEC but this still won't work it still has the same problem reading the Verizon 4G Sim.
I guess my question is... if there is a different rom I should flash it too? Or is it that once it has been flashed from Verizon to Cricket it can't flashed back to be used on Verizon again?

I would just get a new sim card from Verizon, that may resolve your issues. A few questions:
1) Does it still make calls and texts? The main issue is it doesn't connect to LTE? Maybe I'm not understanding your issue entirely.
2) Does the phone have your phone number and matching IMEI (labeled on the retail box) listed in Settings/About Phone?
You could Odin the stock image VRALF2, VRALEC was a pre-release image. Do not accept the OTA then dial *2767*3855# to reprovision the sim card. Maybe see if this resolves your issues.

Well when I brought the phone in the first time to get it activated I was switching from a Droid X so they gave me a new 4G Sim card. But yeah it won't make calls or texts and it won't connect to there 4G data network or pick up the sim.
So are you saying changing it from VRALEC to VRALF2 might fix it?

Oh yeah and I don't have the box it came in but my phone number did show up in the Settings/About Phone
And at the store they told me it was picking up the Verizon network it just wasn't connecting I guess? so it wouldn't get on the internet or make calls or texts

What I was saying is that normally people Odin to VRALF2 or VRALG1 then reprovision their sim card. That code will work on VRALEC but I was just trying to put you on a common starting point since we here don't really use the VRALEC stock tar in Odin. Primarily what you'll find in the stickies are VRALF2 and newer images. VRALF2 was the "store bought" earliest software version of the Verizon GSIII from the summer. Its worth a try but consider the following first.
Since you said it doesn't call/text then I think you lost your IMEI. Could you check for me under Settings/About Phone? It should be 15 random numerical digits if I'm not mistaken. If its not 15 digits, it will be 0 or several 0's. Don't post the exact number if it is 15 digits, but tell me what you see.

No I didn't lose the IMEI it's still there, all 15 digits.
So is it possible to flash a Galaxy S3 from Verizon to Cricket. Then back to Verizon? Is it just a matter of changing to the right software?

Honestly I know nothing about flashing to another carrier. It's not something that I have a reason to research so I'm not knowledgeable in that area. My suggestion still is to run that reprovision code since you've already Odin flashed to VRALEC.
EDIT: To clarify, my suggestion is Odin VRALF2 then run the dialer code.
Just as a precaution, you should write down your IMEI, ERI, and maybe even your MIN and PRL version and store them somewhere on your computer. Since you don't actually have the retail box, this should be kept safe if we can't get this current situation straightened out. My reasoning is if you do somehow lose these before you're 100% fixed, having them written down may help you if you need to use one of the IMEI or ERI tools in the dev section.

Let's see what happens when you follow section 5 of this thread:

Use the official VRALG1 4.0.4 firmware, don't accept the OTA prompt, then try the reprovision code.

Ahh, great! When you do just make sure to root, unlock your bootloader, make a nandroid backup in CWM or TWRP recovery, then use the "Comprehensive IMEI /EFS Backup" thread to properly backup your IMEI.
I encourage you to flash roms until you find something you like. I'll suggest that you stay with touchwiz roms then see whether sticking with Samsung's software in its various forms is good enough for you. If not, there's plenty of AOSP to go around!

So you just followed step 5 on the link above and it worked? (flashing with 4.0.4 ROM)
I'm going through a similar issue and been having a hell of a time getting mine to work. Mine was flashed to work on nTelos which is a CDMA provider in my area. I have flashed to just about everything possible (except 4.0.4) and haven't had any luck.
I went to the Verizon store and they tried to activate the phone but they couldn't but game me a sim to use and told me to call back if and when I could get it flashed back.
I tried at one point to take a working sim from another phone but it will not activate..... will not make calls, will not get data etc etc. when I dial 611 it still goes to ntelos.
Someone suggested putting Phone info on and setting the Phone to RUIM but I could not find that setting in Phone Info (even on the correct phone info, after time I found out the original phone info was pulled from the play store and I had to manually download it.
Anyway with the SIM I have and following section 5 as suggested mine does not give the option to accept or deny the OTA so I can try to enter the re-provision code. Should I get hold of the known working SIM to attempt this?

THANK YOU SO MUCH!!
The key to this however is to have a working SIM (the only one in our workplace was from an iPhone 5), I fashioned a nano SIM to mini SIM adapter and got the info on to the phone then my phone could finally be activated however the nano SIM I used got tied to my phone and couldn't be put back to the iPhone 5 it came from lmao... so I had to run to the Verizon store to get my co-workers phone re-activated.
But going down to the 4.0.4 and VRLEC modem then inserting the active sim, reprovision once it activates (it didnt give me the option to not allow it to do anything), then insert the mini sim, call Verizon they got it activated, I just now updated back to 4.1.1 (need to get 4.1.2) and everything is working wonderfully!!

All of this info is extremely refreshing to hear since I have the same problem with one exception. My s3 has a bad charger port. Sent it in for warranty repair and Samsung said it was moisture damaged and corroded and is not covered under warranty (lies). But that is beside the point and another subject.
My question is, can all of this stuff be done through the sd card and not through the USB? I know it is a long shot but any help would be greatly appreciated.
Thanks!

I know this thread is a little old but I just wanted to say thanks, the exact same thing happened to me (phone was previously flashed to cricket but i was unaware until AFTER purchasing and trying to activate)
ODIN Flashing the OMBINATION_I535VRALG1_I535VZWALG1_743127_REV09_user_low_ship.tar.zip package then reprovisioning with the *2767*3855# worked like a charm, I was sweating for a while as the deal was from craigslist
So far as i can tell to do this you NEED to use the VRAL as I tried a few other (newer) stock files and this was the only one that worked
THANKS AGAIN!

[Q] Box requesting network unlock code won't appear. How do I access it?

Hello,
I am new to the forum and very much a noob. I had bought my SkyRocket in Miami nearly 2 years ago and it came unlocked (i believe the original carrier was AT&T since there was AT&T bloatware, even though there is no ATT logo on top of the screen, it has a Samsung one instead), however i never even had the original carrier's sim chip. It worked fine with two different SIM chips from different carriers until last saturday when I flashed a ROM update (updated to Jelly Bean 4.1.2 Stock) via Odin.
However, whenever i insert my SIM (which was previously working), instead of popping a box/window to request me a code, it forces me to reboot saying there is no valid SIM (print below).
edit: as a new user I cant post the print screen. it basically is a popup where the Title says: "SIM Card Removed", the content says: "The mobile Network will be unavailable until you restart with a valid SIM card inserted", below that there is a button called "Restart", which reboots my system. Whenever i boot my phone with SIM inside this message appearst and I cant close it, the only thing I can do is restart and remove the SIM if I intend to do anything on the phone.
Anyway, I would very much appreciate your help in trying to get that box requesting network unlock code to pop-up, does anybody know how to do it?
ps: service mode runs extremely slow and does not respond to most commands
pps: already tried typing different combinations of the *7465625*638*# codes and the phone does not respond to such commands (i.e., i insert the code but it doesn't display any alert or enter another screen, it just allows me to keep typing)
ppps: I'm also looking for an ICS stock rom to see if I can unlock it using an older firmware, but i can't find an an odin-flashable stock ics for download anywhere
pppps: I've already wiped cache and partition a few times, to no avail.
I know this is a long post, but I really appreciate and thank you in advance for your help.

need to be on stock to enter code, try jb stock
read the 1stop sticky(link in my sig) for all your needs todo so, theres even a free method to unlock sim if ur code fails

The problem started exactly when I flashed the update to Jelly Bean 4.1.2 Stock.

if u read the 1stop sticky, i know its long, u wouldve found a rogers ics for odin, a flashable stock att ics for recovery, and a free method to unlock sim.
what do u mean problems started after updating to jb, was it unlocked b4, if so updating shouldnt have reverted the unlock
edit: reread ur 1st post i think the problem is ur radio(jb radio) for the carrier u r trying to connect to, read the radio section in the 1 stop sticky

I updated to JB using one of the instructions I found on this forum ([HOWTO] NEWB GUIDES To | RESTORE TO STOCK | USE/T.S. ODIN | INSTALL TWRP/CWM | ROOT - thanks for the response here and the tutorial there, by the way). It was unlocked before, but I assume it had something to do with the previous firmware, because the sim unlock stopped working after I flashed JB through Odin.
ps: as I said I already bougght it unlocked and assumed it was from ATT given the bloatware, however my GF just pointed out the rogers logo on the back, therefore i think the hardware is from them instead. I'm downloading their rom and will reflash it and hope it works, i'll update the status here as soon as I make any progress

Hi, i just flashed a rogers rom and it worked. I'm sorry for the inconvenience. But wow, it runs much smoother than it did when running the wrong firmware. Idk why but whoever sold this to me had installed at&t firmware (it was always very glithcy, but i just assumed it was down to the hardware), i know that now because i see that rogers has a diferent intro than att app had either on gingerbread or jellybean.
Anyway, thanks for the help and - again - sorry for taking your time needlessly, i should've paid more attention to my own phone.

[Completed] [Q] Unable to read NV data on Galaxy S2 after rooting

Hello All,
I am new to rooting phones and recently tried something on a galaxy S2. I had a korean version of S2 model SHW-250s which was locked. I lost my new phone so tried unlocking this myself...looked at some youtube videos some blogs and finally decided to use this method posted by someone:
1)Flash these two files using ODIN to convert the korean model into international version :
GTI9100_ext4.pit
9100XWLPW_I9100ODDLPC_I9100DDLPB_HOME.tar.md5 (stock ICS firmware for my country).
This successfully converted my phone to S2i9100.
2)Then to unlock I used a siyah kernel as posted by a developer :: Siyah-v3.2b8
This successfully installed SU and i checked using RootChecker apps that there is root access.
3)Then to unlock my phone i used GalaxSimUnlock app (did rooting as this app required root access)
This successfully unlocked my phone. I was able to call receive messages with new carrier.
I installed some more general apps used it for 5 days.
Sudddenly i started facing network issues. I was not able to make or receive calls. Strangely, I was getting data connection from network but not able to make or receive calls. I could not register on any network.
I tried running GalxSimUnlock app again and it said Unable to read NV data.Since I was naive i tried reinstalling the stock ROM and SIYAH kernel to see if it helps. It didnt.
When i researched further i came to know there's probably something wrong in the NV_data.bin file in EFS . But i hadnt taken backup of EFS previously. Now can anythng be done to restore the EFS and make the phone work? Please help me....
When i run GalaxSimUnlock app it shows everything in green except IMEI number which it blinks in red. But I am able to see a IMEI number and it doesnt look like something default. I am getting everything else MAC id, baseband version etc.
Thanks everybody...please forgive my language if not upto the mark as i am pretty naive about this stuff.

Please Review this thread [GUIDE] Recover your IMEI in 9 steps.
If you have specific question on the process, you can post this thread as well.
If that does not work and you need further help, please post in Galaxy S II Q&A, Help & Troubleshooting

Hey Buddy....Thanks for replying....i just saw you have written you flashed the original ROM on your device again...but as I wrote I have flashed another ROM and didnt take back up of original one and cannot find the SKT korea S2 ROm for this one...Is it ok if i employ the procedure told by you without flashing original ROM...what is CSC? Is there anything else you wanna tell me before i start the process? please forgive for my ignorance Im quite new to all this...

You will have to ask on the thread I linked regarding the Rom. You will have the right experts for your device there.
CSC is sales code., you can check your ROM CSC by dialling *#1234# . First two digits represents country and last three represents release time.

ok thanks...i will post the question there

Per Suggestion from my Collegue @It_ler,
The kernel you have is older. Latest SiyahKernel for the stock JB ROM he has on his device is SiyahKernel S2-v5.0.1.
If you have questions about the kernel, then use the [KERNEL][REF][Q&A] Siyah 5.0+[ICS/CM10] 6.0b5+[JB/CM10.1] +DISCUSSION+. NON-DEV!!! (SiyahKernel discussion) thread.
