It would help to get more info on what you flashed and how you flashed it. Perhaps it's one of those wipe things or what not? Or restoring an app?
I get 'baseband unknown' on a few ROMs that I test flashed. I got it on JMT when I flashed it recently.
So you have to restore from the NAND backup just to get the phone working?
Hello,
I'm having a lot of difficulty getting my Note II (SGH T889V) in working order . I'll try to explain the situation in an organized way. Thank you for your time and kind help!
Background
I have a Note 2 from Wind Mobile in Canada - SGH T889V. I got it 2.5 months ago. It was rooted, was running TWRP and I only loaded one ROM, flashed once, on it - 4.1.2 modified touchwiz ROM. Never once had an issue. The ROM was super stable and in great working order.
I got it unlocked about 2 weeks ago because I was visiting the states. When I got to the states, I put in a T-Mobile sim card which was working great for a few days. One afternoon during my vacation I was having slow data issues, so I thought to change the modem/radio from a Wind Mobile radio to a T-Mobile radio. That gave me 4G data speeds but killed my calls. So I tried to go back to the Wind Radio and that had my phone complaining that there was no SIM card. I went back to the T-Mobile radio and I got calling back but only 2G data.
My IMEI was corrupted - it showed up as zero. I left the T-Mobile radio on the phone when I got back. My home network wouldn't recognize me and thought I was still roaming.
Attempted Fixes
Tried a basic factory reset. Tried a different ROM. Tried wiping all internal data.
I got home and tried to flash to stock ROMs found on XDA for Wind Mobile phones. That didn't solve the issue. The IMEI remained null. The phone would reboot automatically every few minutes unless I turned Airplane Mode on. I figure the phone was looking for a signal and couldn't because of the IMEI problem.
So I looked around on the net and found a link about injecting the IMEI back using QPST (http://forum.xda-developers.com/showthread.php?t=1206275) but I couldn't get the program to detect my phone so I gave up and thought I could just get my binary count to 0 and stock and I'll just take it back for warranty.
I tried Triangle Away but I couldn't get the counter to go to 0 even with stock ROM and recovery. So I thought I would take it to a cell repair shop locally. I took it there and all they did was cause an issue on the phone to make it appear that KIES firmware upgrade failed so that it would be repaired under warranty. You would see a emergency firmware upgrade error the minute you turned the phone on. However, download mode still showed the custom binary count at 1, they didn't get it down to 0.
I spoke with my carrier and with Samsung anonymously, they said the counter would be an issue if I sent it in.
I came back home and tried doing the following, with the hopes of trying Triangle Away again:
1. Installed TWRP via ODIN and ran the restore on the backup I created in TWRP when I first got the phone. I restored everything including EFS. Phone boots to the stock samsung rom but it would restart automatically every few minutes. Even with Airplane mode on, it would still reboot on it's own.
The KIES error message doesn't appear anymore.
2. Went back to ODIN. It was getting stuck on SYSTEM in ODIN version 3.07 when flashing a stock rom. So I switched the USB port on my computer and used ODIN 3.04 then the flashes went through properly with no hang ups.
So I tried to flash a prerooted (http://forum.xda-developers.com/showthread.php?t=1975560&highlight=wind) stock ROM
and
also a basic stock ROM (http://forum.xda-developers.com/showthread.php?t=2061031), along with a stock recovery
Both just get stuck in a bootloop. I tried going to the stock recovery and wiping data, cache, factory reset several times. No luck - still boot loops. Wont go into the ROM.
I did not try "Re-partition" in ODIN. I'm not sure if that'll hard brick the device but maybe that way I can repair all of the partitions? - http://forum.xda-developers.com/showthread.php?t=860432&page=2
__________
Im hoping to get back into a prerooted ROM or stock ROM to try this Triangle Away Method - http://forum.xda-developers.com/showthread.php?t=2272966 to get the custom binary down to zero.
I tried to use the Triangle Away ODIN method but it doesnt go through in ODIN, it just gets stuck.
If I can get into the ROM without it boot looping or rebooting automatically- I think I can fix my IMEI like this person did - http://forum.xda-developers.com/showthread.php?t=2145967
Outcomes Im hoping for
To stop the bootlooping/ automatic reboots, then
1. To get the custom Binary count to 0 so I can send it back in for warranty to Samsung or my carrier, Wind Mobile. The binary says Samsung Official. - http://forum.xda-developers.com/showthread.php?t=2068156
or
2. To get the phone to working order so I can try this persons method - http://forum.xda-developers.com/showthread.php?t=2145967
The phone is still responding and it's still working with ODIN. It makes me think the issue is software or partition related and not hardware related per se. If it is hardware, I just want to get this phone back to Samsung but I need to unroot/clear the binary counter.
The phone has never been dropped or damaged physically. I've really babied the phone. This is my third Samsung Galaxy phone (I've had a Vibrant and S2x before this one.)
This has really ruined my week. I need my phone for work. I greatly appreciate any kind help or guidance. I know the collective genius here at XDA will be able to find a solution.
Thank you so much!
If you have flashed the tmobile modem you will now have to keep the tmobile one in order to get your phone to boot. Flashing a t889v modem will cause loops. Dont know of any way to get back to t889v modems.
Hey, don't worry, you aren't the first to experience this problem. Many users have reported that the T889V will bootloop with the T889V modem after flashing another modem. Many have also restored IMEI and service to their phones, so there is a solution. I don't have the specifics, but there are many threads about this problem with solutions. I have quickly searched for one and I believe it has everything you need to fix it.

Thank you. I'm going to give that a shot. I'll install CWM then install a T889 TMobile Radio to see if it boots.
I'll report back. Fingers crossed.
I had same issue... this is how I fixed it

Thank you all!
I got the boot loops to stop by flashing CWM recovery, then flashing a TMobile Radio.
From there, I followed the QPST instructions of installing a QCN file on the phone to reenable the AWS spectrum. Then I used the IMEI creator and NV Writer programs and I was back.
Data seems alright, getting alright speeds on Wind right now. I just found my bluetooth a little hard to hear in the car this morning.
So with this process, I should stick with a Tmobile radio from now on right? If I flash a Wind/ T889V modem it'll boot loop?
Have you guys noticed any signal or performance issues after restoring the phone this way? I'm wondering if it's worth the trouble to get the custom binary counter to clear and return this phone for warranty. Seems to be working for the most part so far.
Thank you so much again! I thought I was going to have to pay $100 to get it JTAGed.
Glad to here your back and running.
I have a t889v using it on telus, and since I am stuck on tmobile modem I get lower phone signal but never loose signal. On a plus I now get lte speeds.
First day back it seems good for the most part.
Only issue I had was Bluetooth in my car would cut out at a high rate of speed (when I was on the highway). It worked really well while I was on local roads but once I hit the highway I couldn't hear the other side at all pretty much. I had to put them on speaker to hear them. They could hear me really well, better than before when I was driving on local roads.
Never occurred in the past. Could it be a radio issue? Signal seemed okay and I was able to continue the conversation over the phone speaker on the highway.

The bluetooth issue doesn't seem to be a problem anymore. Disappeared on it's own.

I noticed I have serious data issues when the network goes into HSPA+ mode. I get really good data for a minute then it'll cut out totally for like an hour. I tried rebooting, tried battery pulling. It seems the T-Mobile radio doesn't interface well with Wind's HSPA+ . I had full bars but the internet wouldn't load. It was pretty non-functional for most of the day.
It works decently when it's not on HSPA+
Tried switching to a Wind modem, went into boot loops. Went back to T-Mobile radio. Should I try a different T-Mobile radio?
how to fix your T889v if you accidentally overwrite the radio
If you get stuck with no IMEI, in my case, flashed omnirom 4.4.1 t0ltetmo, which uses Tmobile radio... it killed the Wind Mobile radio... restoring form nandroid did not help.
solution:
flash omnirom t0lte (not t0ltetmo) and your problems are gone!

A few days ago I purchased a Verizon Galaxy Note 2 off of Craigslist. When the guy brought it to me I was able to test the phone with my 4G chip. It was able to make calls and access the internet. Once I got home I noticed that the phone would constantly go into a Demo mode and erase any changes that I had made to the phone. Instead of calling the guy that sold me the phone I decided I would just go ahead and root it.
The first attempt at rooting the phone ended up as a disaster. It was constantly rebooting after the splash screen. I later found that this was an easy fix. I had decided to "Nand erase All" and then it would not even boot. I finally found a Root66, the phone came up fine but I had no connection to Verizon with or without the 4g chip. I looked through the phone settings and found that under the "Baseband Version" it said unknown. Since then I have tried flashing in with other roms. Right now its flashed with KIES_HOME_I605VRAMC3_I605VZWAMC3_1098177_REV04_user_low_ship.tar.
Its still says the Baseband Version is Unknown and the only thing that works is the wifi.
Please HELP!!!

I think your EFS has been messed up..what you should do is backup your current EFS even though it's highly damaged.... find a way to recover your EFS search on XDA ..EFS repair or EFS recover if all fails flash a genuine stock ROM and retry the repair or rebuild of the EFS... also as it's a demo phone...there could be other complications..I'm not sure.
seems like damaged efs.. if you had backed up the efs,just try flashing older modem. but if you never back up the efs,it will be very difficult..i suggest you to read all the threads about restoring efs and hope you can fix it.

http://forum.xda-developers.com/showthread.php?t=2392632 This thread should definitely help you. There are all possible ways you can restore your EFS done by @tamirda . I just got my baseband version back on my Note II International GT 7100.
so here's the deal:
my phone no longer recognizes my sim card. at first i thought it was an OS problem. but i flashed the stock. and nothing happened.
i tried re-rooting. but nothing happened.
i searched about it and found out that a lot of people have been dealing with this problem and might be a hardware fault. so i bought a replacement and had it replaced. (redundant) haha.
so anyway after getting it back. trying multiple other sim cards. it still isnt working. and right now im flashing it back again to a stock rom.
if anyone has any ideas. any at all. please. post them. one is better than none.
Check your Imei no. By dialing *#06#.
Does it show your real imei no.?
If no, corrupt efs could be the reason for not showing the network

it still shows the imei.
Update:
so i tried rooting. and flashing new modems? still doesnt work. also please note that it seems super SU isnt working either. i do have the philz custom recovery working. i used the philz recovery to root it then Dr.ketans multitool to flash philz and TWRP to root it. but it seems that it isnt working right.
Background:
I lost MEID then I did full restore with L710VPALEN_L710SPRALEN to get my MEID but asking to insert sim card. After trying to get around it, I gave up and flashed L710VPUDNJ2 without knowing the risk.
Problem:
Since I flashed L710VPUDNJ2 I get 1x on my data. Internet is super slow.
I rooted the phone and flash other modems. Every time I flashed modems, I have no signal, MEID Unknown, Baseband Unknown.
I tried flashed older stock rom (Full restore) Just found out I might brick my phone already.
I went to recovery mode then I see dead robot right away.
Please also see the pictures below because I could not explained it in word.
