[Q] Telus Note2 Rom,modem,signal SGH-I317M HELP Please.. - AT&T Samsung Galaxy Note II

Hello, well here i have been searching for over a year and reading the forums as well and getting more and more frustrated and need a straight forward answer from some one.
Issue 1 i would like to have a custom rom on my phone BUT and a big but it is, that the signal not be reduced in Any way i would not even settle for 1/2 db loss. from what i have been reading the biggest problem is screwing with roms that change the modem file. (am i right?) basicly what i would like is to have a stock android rom (vanilla) like cleanrom, but have my phone signal absolutely equal to my stock, of course if it got better which i don't expect it to, i wouldn't object to that.
Issue 2 How can i back up my current modem on my phone, i have yet to find any info how to do this step by step, or even find a true stock modem file from telus.
Issue 3 Is there a way that if i screw everything up and get no signal or less signal, a way to truly back up the entire phone so i could revert back to the way i am now 100%? ( an example would be if i had a computer and had made a image and burnt it to a cd if i screwed up the computer i would just reload the image and i would be back with every little crum of data from when i made the image). From what i have been reading it seems like most all backup of the current state of a phone don't include 100% everything, am i right or wrong?
Issue 4 Is there any true stock android (vanilla) rom out there ie. not something that someone other than google has made?
Anyway, accept my appreciation in advance for your help, maby i am just stuck with the stock telus offering but i am hoping for some enlightenment.
Oh and one more thing before i go one of the main things about stock that is really ticking me off is outgoing or incoming mms messages that are just pictures show up as a slide show, from what i have read feature.xml has a setting that i can add to fix this BUT i don't have feature.xml on my phone, do i have to download it somewhere and if so i have seached high and low for it and nothing plus is there a specifically formatted feature.xml for telus I317M?
Once again thanks in advance!

There are numerous custom ROMS that do not touch or include a MODEM, so there is nothing to mess-up as it relates to your signal strength. Your only concern needs to be selecting the correct kernel and ensuring you have your EFS partition (containing your IMEI) backed up.

Using ClockWorkMode to create a NANDroid backup and (if needed) restore using a custom recovery like TWRP or CWM is the process you are asking about. THis will fix a soft-brick.
A hard brick...is another story.

Vanilla, would be something like the "plain/boring" interface that comes with the Nexus4. This would NOT have TouchWiz. Your S-Pen will no longer work as there are no drivers for it in the Vanilla interface. It was Samsung that wrote the drivers for the S-Pen and implemented the functionality for S-note and the gestures. Also, the integrated Wacom screen would be useless in the Vanilla interface until someone adds something to the Vanilla configuration that Google deployed (didn't you say you only wanted Google's version?).

I believe your i317M has it too. Most of the good stuff is tied into your CSC anyway, so it's not worth the effort to mess with that. I'd spend the time to play around with the build.prop instead.

Your easiest option is to simply root your Stock ROM and debloat the carrier bloatware. If anything goes wrong, you can always use ODIN to flash the stock firmware (and not lose anything in the process).

I use Telus Note 2 so I'll answer your questions based on my experience.
1) I don't notice signal differences. I've used stock roms, modded touchwiz roms, vanilla android, and I don't notice a signal difference. That being said, I don't check my signal because it's not as important as you finding it important. I don't think an issue at all.
2) Just make a nandroid backup after rooting your phone. Rooting won't change your modem. In TWRP recovery, you can nandroid backup with the modem. Also, some custom ROM threads, e.g. JEDI or Cleanrom have TELUS modems in the original post. You can flash that if your modem is changed (and as above poster mentioned, a lot of the ROMs don't even touch the modem anyways)
3) Nandroid (after rooting). You could also download the stock rom that you are on at the moment on www.sammobile.com (whether it's 4.1.1 or 4.1.2)
4) I don't know what you exactly want. CM? SlimBean? Clairfy please.
Also, I don't use MMS so I can't tell you. But you could always try a custom ROM to see if that helps. I use CleanRom 5.0 myself right now and it's been working fine.

Lost my modem
Hi
I flew off half cocked. I flashed something on ODIN that gave me root but it appears I no longer have mobile data. Ok - it's been fun but where might be the original file for my phone?
i317m from bell. I am downloading the firmware from SAMmobile now - will that be all I need? Aw heck I am dangerous.

Mobile data? Have you checked you apn settings?
Sent from my phone

I live in the sticks, haven't touched my modem files at all (running ProBam) but I recently noticed that while I can send pix as attachments to texts, I cannot receive them. If someone tries to send me a pic, nothing happens. I have tried probably a hundred different APN name settings, nothing seems to make a difference one way or another. There are approximately seven trillion results if you do a Google search on the subject, with just under seven trillion different 'answers'.
As for the modem files themselves, I have never touched mine (other than to back them up) and I am running the MA3 modem on my Telus phone. One thing I have noticed is that I never get LTE, not even when I go to the city where it is, but... Otherwise, I can't complain about the speed. I would be more curious about battery life and wi-fi speeds when it came to modem files, there is a chance that the older modem would work better for people in the sticks.

stock, rooted, that's it.
I am posting this becuase people kind of asked for it, although not so politely.
It's stock with root, therefore i will not be supporting it. I've done nothing to it.
It is not deodexed, or zipaligned, or anything else.
Flash in heimdall and wipe after, as usual.
Enjoy.

After you have downloaded the zip, extract it into it's separate files. Then use Heimdall 1.1.1 (frontend) and put the individual files in the right boxes. Put your tab in download mode (volume down/power on) and flash.
If you want to add dsb9938's overclocked kernel to this, download his Galaxy Cubed 3 ROM on this thread and flash just the kernel. If you want his CWM recovery, flash that too. But don't flash the other files if you want to keep the stock EI04.
You will end up with a stock, rooted ROM with an overclocked (1.6) kernel and a CWM recovery to do nandroid backups and flash mods. Sweet.
D, you are awesome! Thank you.
CW Recovery
Tried flashing (with heimdall) your kernel & recovery from Cubed 3 onto this stock/rooted but I bootlooped - is there something I'm doing wrong?
Also, assuming I'm able to get at least the clockwork recovery flashed, is there a way i can get the CW App you have on the Cubed Roms?
Thanks as always for the great support -

Far as I know it should work. Might have to wipe. I know people have donew the kernel, can't see why recovery would be an issue. Maybe a bad flash?
As for the app, it was made by chainfire, search for it.

Thanks - I'll give it another shot - and yes, I know, google is my friend ...
To verify,
In FactoryFS I place system.rfs
In Kernal (zImage) I place zImage
In Param.lfs I place Param.lfs
Leave Primary and secondary bootloader slots empty.
In cache I place chache.rfs
Leave database, modem and recovery empty.
Correct? Or does recovery get a copy of system.rfs?
---------- Post added at 06:38 PM ---------- Previous post was at 06:34 PM ----------
Note that my goal is to get back to stock so that I can exchange this. I rooted and changed ROM because of the FCs I was getting in machine gun speed since I did the 2.3 OTA. I tried flashing Cubed 3 in hopes that I could get out of my issue, but there seems to be more going on here than a software issue.
I need to get pure stock, and complete a waranty exchange.

This is FABULOUS - Now My GTab is a Useful Tool, Not Just a Plaything
Thanks, dsb9938, for your time and energy put into this Stock+Root Vanilla for Verizon CDMA GTabs! I'm not into playing with different ROMs, and am limited by where I live to Verizon as my carrier, so I was thrilled to find this thread - Root without the learning curve of a different ROM.
Thanks also, to leapinlar for his input - after the holidays, maybe I'll play with overclocking. And, I sent thanks to Glass Echidna for Heimdall and their helpful instructions; this was my first Root (although I'd purchased a rooted cheapie prior to the GTab), but I felt very confident.
I did the Root last night, using Hiemdall 1.1.1 Suite, and it went without a hitch. I was so excited that I stayed up all night, getting Titanium Back-Up Pro wrapped around all my precious apps and data, re-installing, etc.
It's great to know that I can go back to "stock stock" if needed but, in the meantime, get rid of piles of bloatware. I'm an old "mainframe dinosaur" - it's good to get system-level control of my technology, once again. My main thrill, so far, is that I've been able to freeze the stock calendar & contacts in favour of useful ones - eliminating redundancy. Oh - and being able to back up data with apks is a huge relief....
The point of my Thanks to you? I did not WANT "bells & whistles" - just a streamlined machine - and that's exactly what you have given me. I sure hope that you will be creating vanilla stock+roots for many future versions. In just 24 hours, you've had a most positive effect on the efficiency of both my personal and business lives, and I wanted to let you know.
"There is No Free Lunch": I sent a donation (not nearly enough to cover the benefits I received, ) to acknowledge your excellent work. I hope that everyone who benefits from your work does the same....
Can it be used on Sprint Galaxy Tab?
Thanks.

Finaly, I flashed this Rom to my sch-I800. Works fine, everything is ok for me. Intresting thing, the quadrant scoore is lower with this Rom than the stock vzw Rom, but the Tab speed is faster and faster

*HELP*Corrupted Galaxy S II Software?!?!?

Hi Guys. I started a new thread about a week ago but no one has answered in a while and i'm really desperate, confused, and fear for the life of my phone. I had BeastMOD ROM II v3.0 for about a month and one night i turned it off for a minute and turned it back on and i had lost network, i checked and i had no IMEI or Baseband version. I tried a method from another user that is supposed to restore to stock and remove root and it did but it didn't fix the network problem and it would reboot my phone constantly. When i try to do a restore of my very first backup before installing any ROM it gives me a "MD5 mismatch!" error and am very confused. i would really appreciate if someone with free time stayed in contact with me to fix this until it is fixed and give some suggestions.
Did you ODIN back to stock? Or cwm back to stock?
Sent From My Herculean Wizard
I had the exact same problem with my co-workers phone. Since the unlock/efs files have been stashed away in our phone there is no hope in restoring the backups that the device automagically creates.
Your phone is a pricey media player. You need to explore your replacement options or seek a Samsung repair center to have the baseband fixed.

so are you saying that "I" can't fix it and that i should just give up or what could i do to fix it?
Isn't there any way to fix the baseband or IMEI problem, is this a problem with my radio?
The files that control your baseband/radio have become corrupt. It seems to happen at random. You didn't happen to be messing with heimdial(sp?) were you?
There is no way that you can fix your phone unless you go into a Samsung service center, steal their equipment, and learn how to use it.
Flash back to stock, unroot, and ______________. I work for T-Mobile so I'll let you fill that blank in yourself lolol.

Even if you ODIN back to stock the files in your efs directory do not get modified (hence why you keep your IMEI between roms.)

at random? so that means it wasn't my fault? bkz i rooted, flashed the ROM all correctly and was perfect for about a month and it just suddenly happened out of nowhere. I'm on a tight budget and just wanna get this nightmare over with. so do you have any method to return to stock and get rid of any evidence and then get it fixed by warranty? or is this good: http://galaxys2root.com/t-mobile-galaxy-s2/how-to-unroot-t-mobile-galaxy-s2-sgh-t989/

[Q] No data/services after kernel flashing

Hello guys, I'm pretty new to cellphone ROM flashing and modifying.
I successfully flashed the Jedi X7.2 on to my Mobilicity Note 2 T889V, and with a little effort I even flashed the Rogers modem on to it and fully enabled 4G/LTE service since I use Fido, they pretty much share the same frequency.
Then I tried the Bullet Kernel 1.9.01b made by cmenard on top of the Jedi x7.2, which then I lost my data, no 2G, 3G, 4G at all.
So I went ahead and tried to flash back to Jedi with all the wipe data/factory restore and everything, still no luck.
I also formatted the entire sdcard directory, trying to start from fresh, with some other types of ROMs such as MyRom and so on. Now my phone even keeps restarting every minute or so.
After a while I started to become frustrated, it was perfect if I've stopped when I got the 4G, any suggestions? I really really appreciate any input on this problem. Thanks a ton

OMFG, punctuate. My crypto devices can't decipher the longest run-on sentence in history!
To the OP, I would odin the original stock image back onto your phone. Then, update to the latest update via keis or OTA. At this point, you are at least functioning again. THEN, maybe try out Jedi.
Side note, why did you try the new kernal in the first place?

Your posts are really really bad. Not to insult you. But ive read some of them and also you give bad advice and frequently dont really know what you are doing yet you give advice to people. ...this is not good.
OP you lost your data possibly because you did not remove the t889 modem from the firmware that you flashed? Does jedi come with the t889 modem....or t889v modem? What about imei number....do you still have that?
Sent from my GT-N7105 using Tapatalk 2
I'm pretty sure that Jedi X has the saber kernal built in...no need to flash a kernel. The developer is packing it with the ROM because it is not ready to be a stand alone kernel in his opinion (last i read anyways)
I'm on Jedi X and I didnt have to do anything to the kernel and my data works fine (minus MMS)
Hes using CANADIAN T889V
dont you think that has something to do with it?
Sent from my GT-N7105 using Tapatalk 2
Thanks guys for the advice. The Jedi was actually working great, and the Bullet kernel is nothing wrong either, it's just the Bullet kernel I added in on top of the Jedi that screw things up.
Mine is the T889V, the Canadian version of T889, so according to some posts the developers made here the only difference is the modem, and that's why the Jedi ROM has a T889V modem patch.
However, as I mentioned, I unlocked the phone and I'm with Fido right now, and Fido uses Rogers' transmitting towers so I flashed the modem of SGH-i317M to get the 4G LTE frequency for Fido and I actually succeeded.
I'll try something out, thanks guys again.
Any other suggestions are very very welcomed!
I got your PM, but this sort of question is better discussed in-thread.
Let's backtrack a little here...
So you've got a T889V flashed with an I317M modem, on Fido, does service work on it currently? What about your IMEI?
Are your drivers correct? You should be seeing one and probably two serial ports appear in the Windows device manager.
Did you try disconnecting and reconnecting the USB cable after changing to DM mode?

Thanking for getting back to me, really appreciated.
To answer your questions:
- Yes the I317M Rogers' modem did work until I flashed a custom kernel on top of the Jedi ROM
- After the kernel flashing my mobile data was gone, and the IMEI became 0
- My drivers are the newest samsung 1.5.9.0 USB Driver for Mobile Phones
- Yes I did disconnect the device before changing it to the DM+MODEM+ADB mode.

your issues is running a modem that is not compatible with the modules you flashed when you flashed the kernel.
this is why it is a good idea to just run things that are built for your device and your device only. you might have to odin back to stock to get your device working again. you should check your settings>about device> and see if your IMEI is still there.... i would suggest sticking with t mo builds in the future if you are not quite sure what you are doing. blindly flashing things without doing some careful reading can be a recipe for a bricked device or permanently lost data/device ID

- Yes the I317M Rogers' modem did work until I flashed a custom kernel on top of the Jedi ROM
- After the kernel flashing my mobile data was gone, and the IMEI became 0
- My drivers are the newest samsung 1.5.9.0 USB Driver for Mobile Phones
- Yes I did disconnect the device before changing it to the DM+MODEM+ADB mode.

to be honest, that really sucks. not sure what to tell you.
Can you see the serial port show up in Device Manager?

Yes I can, and it can connect too with QPST, just thar it will show "No Phone" and not be able to read/write anything to the phone.
Try rndis + dm + modem, and make sure Kies isn't interfering?
Beyond that I'm not too sure. What exact drivers load for the ports?

[solved] Does T999UVDMD5 lag on your phone?

It all started here:
http://support.t-mobile.com/thread/44716
I griped on the T-Mobile forums about the struggle I've had in finding a smooth ROM for my T999. And I made an off-handed comment in another thread that got me pointed in the right direction hopefully. I'm looking for other T999 owners that have this problem.
The problem on DMD5 is all related to (apparently) intensive tasks. Playing games, mostly. Temple Run 2 and Fruit Ninja, neither of which are all that intensive, were nigh-on unplayable. Other games like Scramble with Friends would lag and stutter a bit, too. So after a lot of searching, I reverted to a pre-rooted T999UVDLJC with the matching baseband, so that way my phone doesn't try to update itself OTA. And performance is pretty good. But I'd like to think that I'm not alone, and I found I'm not alone in this thread:
http://forum.xda-developers.com/showthread.php?t=2326763&page=33
At the bottom of this page and the top of the next one, I found at least one kindred spirit that has a rev0 phone and has the same issue with DMD5.
NO other ROM has this issue. I've tried all of the official Samsung ROMs and I have tried official CM10.1 nightlies and the official 10.1 stable release and performance is very good on all of them. But it took a huge serious nosedive on T999UVDMD5.
So I'm curious about two things:
Does DMD5 run well on your phone? Particularly with games - that's where it was most notable, but even TWLauncher is laggy for me.
How old is your phone? According to the box for my phone it was built 6/30/2012.
If you are affected, could you help us all out on the T-Mobile support forum, and post a message in my thread at the top of the page? If we can get T-Mo and/or Samsung to look into it maybe we won't get left behind. I plan on using this phone for another year or more and I'd rather get the official updates in the future, too.
Update July 6, 2013: I found out thanks to help from people in this thread that I can run mismatched modem firmware/ROM and with the JLC modem on MD5 ROM, my phone runs fantastic. Or at least it has for about 2 hours - usually issues have shown themselves by now, and since they haven't cropped up I'm calling this resolved.
When you were on MD5, how did you update to it? OTA? Odin? Recovery flashable ROM?
And how much data have you been carrying over? (When did you last wipe data/factory reset, without restoring backups?)

Btw, I'm on MD5, completely stock right now. Hw is Rev. 0
I get very little lag, if any, ever. Simple games or even intensive games run very fluidly for me.
For example, I just got Man of Steel when it went on sale and it works almost perfectly. Disney, Gameloft, EA games have all worked just fine.
The only MD5 issues I've seen around here seem to occur when someone is using a mixed build with the MD5 radio. And then its only been reports of heat issues and slight battery issues. Haven't seen much of anything regarding poor performance.

I've tried all of the above. I even let Kies install it once. I've used TriangleAway and Odin to install 4.0.4 and let it do all the OTAs. Iv'e done factory resets and I've told setup not to restore my data to the phone and started from scratch. I used a flashable ZIP with the pre-rooted ROM, and when I did that I also got the DMD5 modem flashable ZIP to go along with it. I've tried not rooted. I've tried custom kernels, and I've tried stock. Odin completely stock and flashable zip totally customized. I've played with custom DMD5-based ROMs with the v6 script and I've tried not. I'm way out of ideas right now.
Sorry, @kennyglass123, I didn't realize I'd checked that box.
Starting to think all of them have "rev 0" for the CPU identifier, so that may not be the way to tell who has what.
Just to be clear, did you ever Factory Reset, then Odin flash MD5 (not mobile odin btw), and factory reset again to ensure internal sd was cleaned out too? If for MD5, you only flashed the Rom and Modem, you would have been on a mixed build. Also, many devs suggest waiting an hour before starting with any testing or reconfiguring. I'm not convinced this is always necessary, but they do usually kno more than me!
Don't get me wrong. I'm not trying to argue against your point, just to make sure not only that you've covered all angles, but that anyone who wants to back up your claim has also done the same.
As for the revision number, it may still be relevant as mine would have been among the first built too. We would need to find at least several others with the same, and different, to know for sure if it matters here.
Its always possible too that you got the unlucky pick of the hardware. (Just as possible though that I got a lucky pick)
Anyway, if you really are having that bad of problems with it, you may want to check if its still under warranty. I don't believe its the norm though.

Yeah I'm pretty sure, but I'm willing to do anything at this point. I'll do it again. I've stashed the Odin tar.md5 file on my backup hard drive, so I'll back up my working config and flash it again. Worst case scenario is that I re-root it, re-install recovery, and then restore my backup. Should take an hour max.
Use the root66 version of the firmware. Its pre rooted and is what I am running right now. Root alone won't have any negative effect, but will allow for much better troubleshooting.
Aside from that, keep it as clean from restored data as possible. Even a single corrupted contact entry can cause services to hang and eat up resources. I wouldn't even flash a recovery until you're ready to restore something.
(I use Mobile Odin Pro and it almost completely replaces the need for cwm or twrp. The only thing it can't do yet is make a nandroid backup.)

So the root66 is an Odin image? I assume you're talking about this: http://forum.xda-developers.com/showthread.php?t=1771687
I've got it downloading now. Thanks for all your suggestions. I've not heard of Mobile Odin Pro, is it a custom recovery?
Whoops - found the Mobile Odin thread on XDA and got the lite version and the T999 flashing kernel. I'll give it a go.
Regarding The AOSP MD5 issues: the same thing is happening to me on stock. Have to use LJC or the battery sucks. What are your reboot habits like?

Yes, root66 is basically just 100% stock firmware, only rooted. Itll download as a .7z file. Just extract it and use the .tar.md5. You have the correct thread.
Mobile Odin is one of my all time favorite apps. Its from Chainfire if you are familiar with him. (SuperSU)
Its not a recovery exactly. What it does is reboots using what's called a flash kernel. This allows it to flash firmware like PC Odin, but also can flash roms that are made for recovery flashing. It doesn't replace the stock recovery like cwm/twrp either, so it also won't trip the flash counter. (I know that doesn't really matter with Triangle Away available (also by Chainfire)).
The only two drawbacks, (minor imo) are that it can't create nandroids, and it doesn't flash the FULL firmware (this is by design though).
I wouldn't bother with it right now, but definitely check it out after testing all this. Theres a free, lite, version here on xda. Ill send more info from my computer later.

OK awesome, I will check it out. I think what I'm going to do right now is just reset the flash counter, flash the Odin image, and then factory reset and set it up as a new phone. Does that sound reasonable? If I reboot into CWM after triangle away, it trips the flash counter again, at least that's what it seems to do, so I can't do anything other than reboot to download after Triangle Away.

I don't reboot unless the battery dies, or I was rebooting a lot when I was on MD5 trying to get stuff to work well. Generally I try not to mess with a good thing.

That sounds fine. Remember, if you factory reset with stock recovery installed, it will wipe internal sdcard.
As long as you have cwm or twrp, the flash counter will always be at 1. I wouldn't worry about that for now though. It won't affect overall operation.

OK, I won't mess with it too much then. I've backed up my internal storage already and I've backed up my SMS using SMS Backup and Restore. That thing has been very handy keeping copies of my texts while I screw with this.
Cool, sounds like you're good to go! Good luck! And let us know how things seem to be acting after flashing.
Don't forget to factory reset after flashing md5.

OK I got as far as the factory reset and then it was time to paint. My daughter's bedroom wasn't going to paint itself. I finally came back to the phone and it was patiently waiting for me to log in. I logged in and installed just a couple apps while I ate lunch, and then it sat until we were done painting and cleaning up. Logged into Facebook and Twitter, set up Google Now and updated Samsung apps. Once all that was done, I fired up Temple Run 2 and it was OK at first, but within 3-4 minutes it was choppy and laggy again. The phone never got warm to the touch. It just ran poorly. I exited out and killed all apps with the built-in task manager, and went back to the game. Not really any better. It's just super choppy. I even turned down all the graphics options in the settings for the game and that made zero difference.
Eventually I gave up. Restored my 4.1.1 backup, fired up some stuff, performance was great. It's just the combination of my phone and that software. No idea what it is at this point. I do appreciate all the assistance you guys have lent me.
Right now I'm on T-mo and was waiting out the 60 days before I ported my wife's number in to my account. Now that that's over, I'll eventually port in her number. She's extremely happy with her iPhone 4s and insists she's not interested in an iPhone 5, so what I'll probably do is use the ability to get new hardware as an excuse to get a Galaxy S4. WHen I first came to T-mo I just got a SIM and bought the phone used - found out later on that I should have just bought a phone through T-mo because I can't get a new phone on a payment plan for a year unless it's as part of a new line. She'll be a new line, so I'll get a phone.
This hasn't put me off on Samsung or even on the GS3 - it's just my phone has a weird issue of some sort. And the people here have been super awesome. Thanks tons for all your advice. In the meantime I'll run JLC and leave well enough alone.

Should I re-flash the MD5 modem?
I'd flash the LJC firmware, Third firmware link in my sig. LJC link is buried in the OP.

OK I see it there. So I should use the LJC modem/firmware with the DMD5 debloat ROM you're going to PM the link for to me? Will they work if they're mismatched? I assumed (not that I'd bothered asking before) that they'd all have to be the same.

boot loop, freedompop s3

Started out with having problems with freedompop, it suddenly started using up all my data for texts and calls, even though I'm on unlimited calls and texts. Tried to root the phone and bricked it.
Then I managed to unbrick with Odin reloading TWRP recovery.
Have now tried 3 or 4 ROMs and they all boot loop. I also upgraded the bootloader because I read you have to have a bootloader that can handle later android like 4.4 or 5.1. Now someone told me they never bothered with that and had no problem, so maybe the new bootloader is causing my boot loop problem? I've tried 2 bootloaders that can handle 4.4 and still get boot loop.
At this stage I'd be happy just to go back to 4.3 stock if it would get my phone working again.
I did notice that it didn't seem to be able to find any checksums when it was flashing, and just bypassed them. could that be it?

Unless you downloaded an md5 file separately, then it will skip the checksum, because you didn't provide one. No big deal, as long as you checked it yourself.
Stop changing bootloaders or you will brick. Nj2 is fine for all current roms. By boot loop you mean it stayed in boot animation? Because lollipop roms do that. Sometimes if it stays for a loooong time, I boot to recovery then straight back to system and it starts optimizing right away. But you may just have to be patient.
(I can't seem to log back on with my other account and it made me start a new account using google....)
I've tried these roms:
aicp_d2spr_lp-10.0-NIGHTLY-20151210.zip
ND8_STOCK_ODEX_ROOTED.zip
and these bootloaders:
L710-ND8-Bootloader.tar
KT747-TW-KK-4.4-SPR-05-13-2014.zip
Is this the info you asked for? I don't know what reg s3 triband is.
I've gone back and forth between the above bootloaders but I think they are the same level bootloaders and the phone hasn't bricked so hopefully that's not the problem. someone else said I needn't have changed the original bootloader to try higher roms like 4.4 or 5.1, but I don't know.

KT747-TW-KK-4.4-SPR-05-13-2014.zip is the bootloader that is currently loaded, should I just leave that one?
the rom that's loaded now is supposed to be stock 4.4. It does the fancy sprint splash screen, then the word SAMSUNG appears and just stays there forever, with a blue shadow fading in and out.
Maybe I should try a different ROM? The other one I tried is aicp_d2spr_lp-10.0-NIGHTLY-20151210.zip, that also boot loops with a spinning pattern with icy android robot.

Well kt747 is not a bootloader, its a kernel. And it's a kernel for stock 4.4.2. Stop flashing random things or you will destroy your phone. The difference between regular and triband s3 is big. Regular is sph-l710, the triband is sph-L710t. That little t makes all the difference. You need to check your model number.
Use odin to flash nj2 stock .tar and start fresh.
Get it here
You will also need the freedompop messaging app for your phone to work.
Got it back again with the nj2 stock.tar! Many thanks
Can't get freedompop messager because google play thinks it's already installed.
Mine says SPH -L710 on label behind battery, so I guess it's not triband?
CAn I now root and install a custom rom eg with android 5.1 and is it worth the trouble?

It is not a triband. Congrats on fixing it. Yes you can now easily root, using odin to flash the most recent twrp tar file for d2spr (our s3's codename).
5.1.1 roms were (are) worth it for me, but everyone's taste is different. I'm actually running aicp 11 (marshmallow 6.0.1) right now!
