For those with bootloops after flashing a modem
I just wanted to post this in order to help a few lonely souls out there with bootloops after flashing a modem and unable to access recovery (TWRP or CWM) and not even able to flash in ODIN... (as it happened to me, lol)
If you are in bootloops...
Flash this CWM from the N7100 Forum... (Flash it thru ODIN)
and you will then be able to access recovery (by pressing and keep holding volume up + home button as soon as it restarts) and restore/flash older working modem in order to solve the issue... and unbrick the Note 2
hope this help some of you guys...
Just click thanks! lol

I believe he can access CWM or TWRP. The problem is (also my problem) he cannot flash his original t889v modem without it going into boot loop. The only way for him not to boot loop is his installing a tmobile modem which he has to do from CWM or TWRP. He wishes to keep his counter to zero he doesn't want to install cwm or twrp as it will increase his counter.
Has this issue been fixed yet? And I havent rooted/flashed any roms yet can I extract the modem and then simply flash it ontop later? Or unpack the rom ans replace it from the start?
I'm not aware of anyone fixing the T889V LJ4 modem-related bootloops.
My T889V still works with the I317M LJ2 modem (I did have to repair my IMEI) which is OK in my current situation (I'm on VMC and got the T889V because: I also use T-Mobile USA sometimes, it was available for cheaper than the I317M).
I however doubt that HSPA AWS would work in this configuration, which does little good for Videotron, Mobilicity, Wind and T-Mobile USA users.
MCRHAZ, since you haven't touched your GN2 yet, could you look at this thread and attach a full NV T889V stock NV backup? Don't forget to remove your IMEI from the output text file. (That'd be item 550)

okay I will do that...I'm just waiting for my exams to be done and over with so I could finally look more into these things with the intent of doing it then and not later on lol.
So my exams are done by the 16th, hopefully I can be of help after that date, but I want to know what good that would do, by uploading the stock rom, if its possible. What I mean is what purpose would that serve? for people to flash back to stock? or for modem extraction? or to use as a base? or all of the above. If it's such an important thing than how come no one thought to do this before? or if they did what stopped them from doing it?
There's no huge rush as far as I am concerned, my phone works quite well with the 317M modem in the meantime and I don't need AWS HSPA for the foreseeable future.
We already have the stock ROM and modem on hand.
The backup I'm talking about is going to be a 3MB or so .txt file. The NV items (NV as in non-volatile, afaik) are a database of sorts for modem settings, not unlike the Windows registry. It's a Qualcomm thing and they've been using them for many, many years. Most settings are not readily editable other than with specialized, leaked software: QPST and QXDM. The thread I've linked has a freeware tool to do it instead.
As far as not having thought of doing it before: a lot of people (myself included) thought that just copying the /efs partition was enough to recover the IMEI on this device. I had done this before modifying anything on mine. It's not. Misleadingly, it is adequate on many other recent, non-LTE Samsung phones (incl. GT-I9300 and GT-N7100) that use Samsung's RIL and have no Qualcomm radio hardware.
Another poster (deeznutz1977) kindly sent me his backup the other day, but his device is a T-Mobile T889 which may have some differences compared to the T889V. This is what I'm trying to check with your backup (or anyone's who'd beat you to the punch, really).
My working assumption is that restoring those NV settings might enable re-flashing the stock 889V modem and solve the bootloop problem a few posters have encountered.

You may well be right. However, there may be truth in peoples claim for the reason that, this modem may be from a MCT rom or for the MCT variant. I say this because people reported that they were not able to flash the MCT stock rom onto their Wind Mobile phones, it resulted in a bootloop. I was always under the impression that MCT and wind where the same devices and thus firmware would be exactly the same but I guess its not. Therefore the modem you kindly posted was for the MCT variant devices and not wind mobile ones. I could be totally wrong, as I have little to no knowledge on these things, just trying to bring light as to why this modem is bringing havoc upon some wind mobile variant devices.
okay, thank you for reply. I have another question though, is there a way i can just extract the modem from my phone (unrooted stock)? And use it to flash it compounded with your MW rom? Just to be one the safe side.

DO NOT INSTALL ANY MODEMS ON A WIND MOBILE PHONE. PERIOD.. IF YOU DO YOU WILL CURRUPT IMEI 100%.there is no fix for us with wind phones I had to send mine to the states to Jtag repairs for it to get fixed.. I tried everything to fix the imei.. but none of the solutions that work for other models of the phone would work for out t889v models.. please do not install any modems on your phone or your phone will be an expensive paperweight. .
