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.
hi there, i have a big problem, my n7105T from telstra australia is not working. it happned after i flashed it into a different firmware, and the pc suddenly shutdown. the imei is now showing null and baseband unknown, ive tried each and every steps i found here but nothing seems to work. cant even generate a dummy imei. (was not able to back it up)
steps tried;
reflashing it back to stock rom
tried the 9 steps process
also 3 technicians tried to fix it using different boxes, octopus, spt, nspro and dont know what other boxes they have tried. my phone stayed even for 2 weeks to one of the techs since he was really challenged on fixing my phone. but still no avail.
my efs is all empty regardless what rom your going to flash it to.
pls help, willing to pay if needed.

Hi,
I recently, flashed a bunch of different ROMS and modems to try to fix my original service issues on my T999L.
Being a noob that I am, I went from 4.2 and numerous other versions, and a couple ROMs had service, but most didn't. I thought I could fix it with flashing a new modem but that killed my service completely (IMEI null/No SIM card)!
SInce then, I flashed back to Stock ROM (using ODIN) and regained SIM recognition, but now my service sends the same text over 10 times, and I keep receiving the same texts messages. Even on wifi, I noticed that I am having issues (when I download apps it only gets to 90% and never finishes).
Does this mean I may have screwed up my EFS files? I never backed them up, and now I am in stock ROM with really strange service issues.
Will flashing a new modem help, or is this how I reached this point in the first place?
Any help would be greatly appreciated! Thanks in advance!
Okay so i have the T-Mobile Galaxy s3. It has been rooted for a while with zero problems. I got tired of the older android on it and decided to install a rom. I installed Cyanogenmod 13.0-20151208-unofficial-d2tmo running android 6.0.1. When i first got it all booted and loaded with gapps, i noticed that it recognized my sim and that i had a signal but i couldn't use any LTE or just all around data. basically i couldn't go online (in case i just didn't explain that well enough. Phone service is a mystery to me). I did some searching online and found a lot of people saying that i needed to update my baseband. i found a baseband for my model (T999) and tried to flash it in TWRM. Once i rebooted, it said "No SIM card - No service." in the upper left-hand side. i have tried flashing multiple different basebands the same way with no luck. i tried backing up my EFS folder and the restoring it because someone said to do that and that just... just no... it didn't do anything. even Odin 3 said it was a "FAIL!". So here i am with this android equivalent to an Ipod and i hate this. Everything else in this ROM works perfectly aside from this but this is a super big problem. PLEASE HELP!!!! A phone isn't a phone if you cant even send a text.
Did you update the phone's bootloader and modem to the latest version before flashing CM?
