How imporant is it? ive been flashing roms back and forth aosp and touchwiz jb and i havent lost my imei should i back it up and if its actully necessary can someone kinda dumb it down a little so i could understand easily
Thank you!!
I would say.. if you can then you should back it up. Reason being.. it seems to be a lot easier than going through the process of putting it back onto your phone when it's missing. That being said, I have done the same thing and have not lost my imei. At the same time, I also know that there's a way to get it back so I do not worry about it. But, you could go here http://forum.xda-developers.com/showthread.php?t=1801997and back it up. to me, it's only as important as you see fit. meaning.. if you think it's more work to fix it after it's gone then back it up now. if not then dont worry about it.
It's like insurance, you only miss it when you need it. It costs nothing to do it and is obnoxiously easy to do so.

I backed mine up right after rooting before I started flashing roms. It only took a few minutes and I've had to restore it once since then, and it was very easy. Back it up and keep it in a couple of places. I have a copy on my laptop and on a usb stick.

Thanks for responding were you as well on aokp 4.1.2 and on ktoonsez kernel while backing it up? do i just download the software and say backup easy as that?
Thank you!
Edit: downloaded software now i need to know how to get on diag mode do i just copy and paste it to a script runner on my phone??
Yes, when I lost it I was on AOKP. Instead of messing with dialog mode to get into the hidden menu, I restored a nandroid of stock that I made right after I rooted. If you have a stock backup, back up your current rom, restore your stock backup and do it that way if you're not comfortable with the dialog. You can then restore your current backup after you get your imei backed up or restored. Hopefully someone can help you out if you don't have a stock backup because I'm not familiar with the other way. Just read through the thread and look for the info you need.
First thing I did after rooting, restored imei twice now. There are a couple or roms that eat imei's and gps.

all went well except that im not sure if i backed up right because the picture isnt a phone and the backups name by default was 00000000_0 cqn i finished at 100 percent and im able to find the backup in the bin folder but i just wanna know if i did it right. can any one confirm i have a screenshot as well
Thank you!
This is my last ditch before I pull my tail between my legs and run off to ATT and concede defeat.
Bought my GS3 from ATT in september and have ran CM10 Nightlies since the first day. No issues and everything worked great. It took me all of 5 hours to begin to hate TouchWiz. Anyway when CM10.1 (4.2) was released I immediately upgraded using the recommended method this thread here. Used TWRP, factory reset, installed the rom and correct 4.2 gapps. Reboot, worked great, fell in love. However, my cell data was nothing (no edge, 3g etc...) at first I thought it was the modem issue being discussed by some ATT users, I flashed a couple modems with absolutely no affect. Entered a whole array of ATT APN's. I fresh reinstalled CM10 using the same process, factory reset, 4.1 gaps. Now I can only get Edge data, again cycled through a whole array of APN's and modems. I reverted back to stock TouchWiz, nothing, still only edge. Somewhere in the mix my IMEI was erased and showed 0. I restored the correct IMEI and it displays correctly. Still only edge, installed CM10.1 again, antenna works, however only in edge, back to CM10, only edge. Now I'm running Unrooted, stock Touchwiz with the flash counter reset. Completely bone stock, no root, 4.1.1 ATT Touchwiz, fixed IMEI.
I'm at a loss guys, I've looked at similar "edge only" ATT threads and nothing helps.
Do you have the right network type set?

It sounds like you lost your IMEI.

IMEI was corrupted however has been restored and is correct.
New symptom. Battery is all over the place, shows sporadic draining, recharging while not being plugged in. Phone will shut off when battery reaches 0. I remove the battery and boot the phone and it has substantially more. This last time it went back to 50%.

I was halfway thinking this. I have absolutely no clue how a flash could have caused this. It has been in a case its entire life and is so far without any significant impacts.

It's nearly impossible to cycle a battery in full now. I get maybe a few minutes of uptime, shows massive drain, reboot and it's back to normal only to recycle its process.
You should just Odin back to stock and start over.

Something similar happened to me. It didn't matter that I had restored what should be the proper IMEI (I hadn't backed it up first, only recovered it). I never could get the phone to do anything past EDGE network. I spent over an hour on the phone with AT&T support trying to get it to work, but couldn't.
That being said, did you make a backup of your IMEI before you began flashing, or did you try (like I did) to restore it after it had been corrupted? From what I know, if you have a backup from before it got corrupted, you should be ok. However, if the IMEI restore was done after it had been corrupted, then it may not ever work.
I eventually had to send my device back and get another one.
Okay, so Ive gone from flashing MyRom, MyRom Mods and then a softbrick.
Ive flashed stock UVTALL8 using odin (a number of times). Maybe once with repartition and once with Nand erase all because I couldnt get the soft brick fixed :/
What got me out of soft brick was when I flashed TWRP via Odin and hence got a working recovery.
I can now boot up the phone. Everything seems to be working.
Except that I have no cell service. IMEI, Baseband and other About Device information is missing.
Ive tried flashing the kernel and modem for UVTALL8. Still no fix.
And my phone internal storage says I have 0.00mb and I get occassional errors of I being full.
The fact I got a working rom gives me hope.
But if anybody awesome could point me in the right direction of full stock and fixing these issues that'd br awesome.
You flashed with Odin and repartitioned...really? Did you really do this? Sounds like you have really screwed the pooch on that one.
I have no Idea where to even begin to help you man, but when flashing in odin to prevent problems like this you ARENT supposed to check that box. That's like the first thing you are supposed to know before even using odin.

Do you suggest I ODIN UVALK8 (which I initially had).
I'm assuming I'd need a PIT file to get my internal storage working again? Right?
And what is this efs thing I keep hearing about?

bro.... honestly, you are basically screwed. no easy way to say it. time to get a new device.
your IMEI is gone. you have no back up, you have flashed an odin image multiple times, wipe your device clean and dry. still no signal, obviously.
this could have been avoided had you been instructed to back up your efs parition, which is where the device ID (IMEI) is stored. this partition, for reason still unknown to me, can become corrupted during flashing of recoveries, ROMs, kernels, whatever... you are not the first person this has happened to, and there is no way to restore a backup of something if it is not backed up. like i said, not your fault, you should have been told from the get-go to back up this vital information as soon as you rooted.
sorry man. like i said, not your fault.
And how is this vitle information backed up?

There are a few ways. The right way is open to debate.
There is an option in twrp. There is an app in themes and apps called Andromizer that also has an option for this. Others slip my mind.
My opinion is to back it up several ways and store the backups in more than a few locations, (SD, pc, Dropbox, other cloud storage, cd etc). The ability to restore this is vital if it gets lost.

There's a number of threads on this topic, but in the case of Qualcomm modem based devices, you need NV item backups, which can be made with some tools you'll be able to find out here. Just backing up /efs isn't enough.

Since you did a NAND erase you basically deleted the partition table and all NV data. I had the same problem and simply flashing things aren't going to work. Here's my thread http://forum.xda-developers.com/showthread.php?p=36010956#post36010956
You can try to flash the pit in heimdall and see what happens. What I ended up doing was restoring everything to stock, using triangle away and sending it into samsung. They replaced the mobo and sent it back to me for free. Good luck bro.
i lost my imei /baseband etc from flashing myrom v2 and i fixed it by going to TWRP and wiping the 4 main things and than flashing cyanogenmod

So it really wasn't lost, it was just not displaying and registering the data
So, over the past, well I don't know how long... ever since I started using my galaxy s III back in July, I have seen these threads pop up, and more so recently (to be quite honest this is a disheartening thing to see, and can easily be prevented, but we'll get into that) that say "hAlp ma service is teh failll I kant haz no moAr IMEI!!!" -__-
What is lacking in most of these threads, situations, occurrences, whatever you wanna call them - user error, lack of responsibility on this forum of the developers around here (myself included) to instruct people from step 1... BACK UP YOUR EFS PARTITION! There are many ways to do this, terminal emulator, the andromizer app, some handy tool I have seen floating around here where you connect your device to your computer, open it up, so on so forth. Everybody should be doing this. Everyone. But that is hardly the issue, nor the point of this thread - (pointing fingers).
Last night after seeing ANOTHER one of these threads where somebody had lost service to their device, costing them a good amount of $$$ now, it dawned on me that maybe, just maybe, the issue isn't that the partition is actually being corrupted, but maybe there is a problem occurring where the device doesn't actually read it - some type of failure or registry during booting. All of these instances have had one thing in common - the IMEI mysteriously disappearing and no service issue happen after boot up. And not necessarily after doing any 1 particular thing... granted yes, flashing a ROM, but that should have nothing to do with your IMEI not registering on a network unless said ROM has some kind of issue/bug whatever where it is simply not displaying such information in the status bar (unlikely, but who knows at this point, right?)....
Again, back to last night... I was curious to see if I could duplicate this issue that a user reported where they had flashed a kernel and their IMEI had disappeared. So, I picked some random kernel from asylum that carried the same 7500 device ID that my currently running kernel has of his (running asylumcore)...
Downloaded it, flashed it through cwm, booted up, BOOM! No IMEI. No service. Interesting. Didn't restore my backup of the efs partition which I had made a month ago, for obvious reasons stated - wanted to see if the partition was indeed corrupted, or if there was simply some kind of disk read error.
So I booted back into cwm, flashed back to my other kernel, booted up, and wouldn't you know it, IMEI and service was restored. So what does this mean... this means that the IMEI isn't, hasn't, never was, "lost" per say - there is simply an issue causing it not to be read properly.
So to troubleshoot this issue properly, I need people to pipe in who have "lost" (not really lost) their IMEI's. This is what I need to know:
what version of recovery were you using?
what ROM and kernel were you running right before this happened? Need the revision, android build (jelly bean, AOSP, whatever), everything, details please.
what did you flash or do to the device right before it was gone?
were you able to fix it? - a backup, reboot, reverted back to previous firmware? what?
This will help quite a bit. So far I have been able to duplicate a "lost" IMEI on my own device 4 times in a row, and been able to get it back without any kind of back up. I need some more information from some of you, however, to say 100% what is causing the issue.
Also, since we are already here. I will simply say that developers around here need to take more responsibility in their little "disclaimers"... seriously. If we all know that this is an issue, then we should be instructing people in our ROM threads to take measures to prevent this kind of thing from happening. Especially since at the moment it appears to be random, and especially since there are plenty of methods to be prepared for it. Just sayin.
Something as simple as this:
"Warning, certain users have an anomalous issue of losing their cell signal and having their IMEI not registering. It is highly recommended that if you intend on flashing ANYTHING to your device, that you read threads regarding this issue and furthermore that you make a backup of your EFS partition on your device to prevent permanent cell signal failure - in the event this anomaly happens to you, you will not be without a working device and out $600. Developers are looking into this issue and working on a fix, but as of yet, there is not definite fix. MAKE A BACKUP!"
Then how about a link to that thread for the andromizer app that is not stickied, not looked at ever? Not too hard to do. And would have been nice for those who were suddenly caught off guard by their device turning into a paperweight. Here is the link:

I am working on a write up right now to fix IMEI issues.
Sticky this. Excellent work and ingenuity. Im subscribing to this thread.

From what I've gathered by reading here, lost IMEI issues due to kernel or ROM flashing can indeed be resolved by flashing back to whatever was working in the first place.
In the case of modem cross-flashing however, things aren't as cut and dry. I pulled an NV items backup (with NV_reader_writer) from my phone prior to restoring it to service with a backup from a working phone, and NV item 550 was returned as inactive, along with a bunch of others that shouldn't have been.
Very interesting write up here. I did actually had this happend to me on my GS3, that I purchased new from T-Mobile back in November. The first night I had it, my flashaholic itch kicked in. Before I knew it I was in the process of rooting the GS3....but all hell broke loose once I rooted. The Root kit at the time had a earlier version of CWM and it caused me to lose the IMEI# when flashing a CM10 rom.
So I did the whole process of reinjecting the IMEI# bla bla bla, I was able to retrieve data and IMEI. No issues what so ever after that. I even just in case did the whole QPST tool of backing up the IMEI# for just in case purposes.
Well a week ago, I was planning a installing a theme over the current Wicked Rom on my GS3. So I did the steps going into recovery, Wipe the caches and went to install the theme when I realized that out of my stupidness I never downloaded the theme. So I just did a simple reboot from TWRP 2.3.3.2 I believe if not it was 2.3.3.1. And once the my phone booted back to my home screen I had zero data.
So at that point I was utterly confused in what had happened. All I did was wipe the caches, I had no clue that the caches have ties with the EFS partion. Still till this day I have no Idea what happened.
I want to try other roms but I just so scared for this to happen to me again. What should I do to stop from having this happening to me again?
Thanks
So I knew the first thing to do is another reboot just to see if something might of hiccuped during the booting up process. But once it booted up again and back to the home screen still no data. Not even Edge, Had the Cancel symbol over my bars on the status bar. So I knew to check the IMEI# under phone status and sure enough it was not there just displayed Zero.
I knew I had a back up of the IMEI# so I tried to just reinject it, Since I knew it was basically a painless process. After doing so, Still no data, even though the IMEI# is showing CORRECTLY under phone status it still would not kick in even Edge. Eventually Edge would connect but it would be like Dial Up speeds.
So I Odin'd back to a Root66 stock rom and checked the status of the data and still no go. Everything is still showing under phone status at this point, so no loss of the IMEI# but no data at all.
So I Odin'd back to the T-Mobile Stock Firmware and same results and just for kicks I tried to reinject it once again and still nothing.
Ended up conducting the triangle away process, got it back to Samsung Official everything and even the Modified Status was set back to Normal status. Everything was back to stock at this point, Kernel, Modem, Rom, Bootloader, just everything was stock as if I just bought it. Still no data.
Conclusion I did a warranty exchange, got the new GS3 fully working ofcourse, gave it to the wife and bought me the N2.
Now I am terrified to do anything to this phone. I'm currently running MyRom Rev V2 and have a nandroid of the Stock firmware.
Sounds like the issue may have something to do with recoveries
same here !
My galaxy note 2 . I root the phone and put room T889_N7105ZHALJ4 it work fine for awhile but It have robot voice when calling .
and I try to boot another rom PhoeniX.ROM.v4.0.by.tamirda-signed this is big problem .
This rom make phone unable to connect network . after that I try to flash back old rom . It same thing . Make phone able to connect network .
My phone is now dead . only connect wifi . Try to call customer service . And now they have to send me another phone .
No idea after what 4 years of hacking android phones not once had that happened. Now I feel like a complete amateur because of that.
I'm literally terrified to do any thing else with my phone and I'm not at all that satisfied with the choice of rom I've selected either but it'll do till there is an answer for all the random issues people having with this generation of "Galaxy" series phones.

At this point I performed nandroid backup and efs backup and attempted to flash jedi x. As soon as I did this I lost service...it has bars but no voice calls and no 4g. My IMEI still shows however. I ve tried everything from stock factory restore through ODIN to restoring efs, flashing stock radios/kernels restoring nandroid still cant get service, defintely need some step by step advice on how to get back my service.

I paid full price for my phone so.. no insurance, and even if I could what if I experience the same problem with another Note 2? Then I just lost more money and time. I followed all steps correctly for T889, I feel like this should be reversable if I have nandroid backup and EFS backup. Hopefully developers can help us out with this to figure why this issue is occuring in some Note 2's and not in others.
Yes please trt figure out how to fix this issue yes I also notice people are hav8ng lost service or instability data due to this problem with flashing. I encounter this problem I and lucky fof me tmobile sent me a new phone due to claim it was defective.

I can't believe all these pple are saying help me help me.
The OP has been kind enough to risk his note 2 and lose imei intentionally to try to find the cause and a fix.
He clearly says, to do this I need everyone's help who's lost imei (I need as much detail as possible. Rom, kernal, modem, version of jelly bean, version of twrp. Flash anything before lose? Mods,tweaks, themes, scripts if so what?)
That's all OP is asking for and not one person has been specific
And I don't think OP has replied to anyone. Who knows probably gave up trying to find a fix.
Haven't given up. Just don't have enough data to conclude what the issue is. All I know for certain is that when it is "lost" it isn't really lost, just not registering the info or reading it.
But yeah, not a whole lot of input.
Hey guys just fyi to let you know what I found with this issue. Just giving my input.
Well it looks like my imei is populating but my note 2 no longer gets service. Im probably going to warranty it so I can get service again I spent all of my weekend trying to fix. I think this issue may be related to something within the modem or radio being flash incorrectly and somehow corrupting the efs files. I searched forums about efs corruption and I think maybe it has something to do with a nv_data file missing? Not sure if that applies for sgn2 but I couldnt find or maybe I dont know WHERE to find it in root explorer. Maybe if we compare a working sgn2's efs file with a NON WORKING sgn2's efs file maybe that would help? I followed the steps in the t889 root guide step by step... and then as soon as I flashed Jedi X9 through cwm recovery BAAM...service was gone.
I tried reflashing, I tried reflashing stock modem\kernel and reverting back to stock via odin but no go.I did notice it was able to connect to tmobile for one to two sec because it would actually sync the time and date after turning on for the first time. But never again after that. My Imei and bars are showing ..but when I make a call it says "not registered on network" and no 4g either. I think this may be because the rom had included a different radio not sure which one defintely wasnt the canada ver. Flashing this rom somehow made my phone stop receiving service...Does restoring efs backup a guaranteed fix the lost imei/ service issues? Can flashing using earlier version of odin cause an issue? I used 1.84. Everything passed successfully however. Just throwing ideas to help. I definitely want to try to avoid the issue when get my note 2 back from repair.
Before I had this issue I had the latest stock firmware from tmobile the 889VALL4 modem and kernel 4.1.1 jellybean. No problem rooting the phone and still had service after root with chainfire method.
My guess is the phone doesnt have true root towards the efs/modem/nv levels with the current custom recoveries available... its like twrp and cwm arent messing with those files but when flashing certain roms those files are being mishandled.... therefore creating the restore ineptitude
Ultimately I have only used well known roms and kernals that others have tested without hitches (for all my android devices) like CM or Jedi... those "third party" roms arent trustworthy in my mind as to some devs "open source" often translates into "cut and paste" which can be problematic to say the least
With the GNII, i have used CWM (not sure on build but I can find out) and TWRP (only 2.3.3.2 never 2.3.2 or whatever was before)... and like I said "well tested roms/kernals" so cf_auto_root, then Teshxx lk8 stock, then Teshxx ll4 stock, then Jedi 9 with saber_7+, then Jedi Master 9 with Saber 10.2, and finally switched to the Perseus kernal 3.0.36 alpha 32...
Never any issues with connectivity, imei, anything...
Hope this helps and more importantly you find what is lacking and get the info to CWM and TWRP for updating (id say let the rom devs know too but by bettering the Custom recoveries, roms like all other devices, wont affect those files

I will add no roms were ever flashed through CWM... only had it because I was use to it and new to TWRP... my Bro in law made the suggestion and it looks like its the best advise he could have given me to this point... that and my overall patience to not jump the flash gun... again I cant stress this enough, only use well tested roms/kernals/etc... I know CWM came by surprise as we all have grown to love it but its not perfect and even other recoveries were there before (RA, etc) and it wont be the last (TWRP)

Anything you have to do differently trying to do this for the GNII?

I "lost" IMEI lastnight, Just got the phone rooted with Exynosabuse. Then i Flashed CF-Auto root with mobile odin. Then I flashed Note2Core 7105 with Mobile odin.
When i woke up in the morning I noticed no signal, Baseband is unknown and so is IMIE. And I didn't back up EFS. :crying:
I booted into recovery and wiped still the same. I also re flashed the kernel.
Downloading stock rom hoping that will work :fingers-crossed: This is a N7105T ( I know this is a T-mobile thread)
Follow this guy he fix his lost imei and baseband I dunno it might work

I recently lost my IMEI and didn't have a backup. Stupid move on my part. Now I know I need to do a backup before flashing ROMs. Anyways, I just got off the phone with AT&T and I will have a replacement here in 2-3 days. As I'm sure most of you know I'll have 10 days to send my old one back. Before I return it to stock and send it back I am willing to help in the research of this problem and a potential solution. I have done a lot of searching on this forum and I haven't found a solid solution. If anyone has some theories they would like to try you have a few days to let me know and I'll see if I can be of help.
Here is the history of the phone as best I can remember:
-Bought brand new December 7, 2012
-Updated to Jelly Bean 4.1.1 through Kies. No noticeable problems
-Rooted with Odin v3.04 Team Epic Root from Recovery with CWM v5.0.4 and Super User I kept the stock ROM for awhile before flashing anything else (Made a Nandroid of this ROM) No noticeable problems.
-Flashed Drew Garen's Serenity 1.2 No noticeable problems
-Flashed Pure Motive's Galaxy Mod Rls 14.1 No noticeable problems
-Flashed Pure Motive's Galaxy Mod Rls15 (This is where the problems began) Did a full wipe (data, cache, dalvik) like I always did. Rebooted after flash and noticed that my service sucked and my data wouldn't connect. I checked the APN's and they were wrong. Changed the APN's and the data would connect but I still had poor service. The phone wouldn't even make a call. It took me a little while to figure out that the IMEI was missing. It just read 0. After some searching I found a method of injecting the IMEI: http://forum.xda-developers.com/showthread.php?t=1804117 I used this method and put the original IMEI back in. Of course that didn't fix my data or poor service issues.
-Then I tried Peoplearmy's method: http://forum.xda-developers.com/showthread.php?t=1801997 Actually I only did the make a backup part with QPST. I couldn't use the QCN Generator app because I only had Windows XP and the app requires Windows 7.
-I flashed my Nandroid backup. No help.
-Flashed Stock Jelly Bean I747UCDLK3. No help.
-Rooted the phone again, using the same method as above.
-At this point I became desperate (stupid) and tried a method for the GT-i9300: http://forum.xda-developers.com/showthread.php?p=30773406 This definitely didn't work and now I lost my serial number.
-Last night: Finally got access to a Windows 7 computer. Tried The SGS3 QCN Generator app. This time it worked and made a QCN. I injected it into the phone. No help. The QCN data I used was from after I lost IMEI and had manually put it in. I'm not sure if this is part of the problem of why it didn't work or not. The way I understood things it was supposed to repair the other parts of the QCN data. Someone please correct me if I'm wrong.
-I actually made an EFS backup on Galaxy Mod Rls14.1 using the Aroma installer. From what I've read this wouldn't necessarily help anyways because it doesn't contain all of the data needed to do a complete backup which is kind of beside the point because it's in tar format not in zip and it's a tiny file. 58 Bytes.
-I have installed Root Explorer and looked in the EFS folder and it doesn't contain any nv_data files.
I have already installed Triangle Away and cleared my flash counter.
So, if anybody who actually knows what they're doing (cause I obviously don't) would like to help, especially if my situation can be used to fix/prevent this from happening, and wants to use me and my I747 as a Guinea Pig let me know.
-Right as I was getting ready to post this I scrolled through settings>about device>status, and my correct Serial Number was back. What the ....? The only thing I've done to the phone is toggle airplane mode a few times, turn it off and on a few times, used wifi to get online, pulled the battery, booted up in CWM recovery. I haven't flashed anything to the phone. This is odd. Any help or feedback would be greatly appreciated.
Huh? There's a perfectly good solution and a fix. Not sure why itnwouldnt work for you. It works for everyone else.

I tried that. Exactly step by step. I still don't have reliable data. It either doesn't connect or stays on Edge. Also the service sucks. Everyone else around me will have 3-4 bars and I'll have 1.

Changing your modem can fix that.
I was thinking of that but I read on here somewhere that someone had tried it without results. I am willing to try it though. Which modem would you recommend? I already have i747UCLG1 modem on my memory card, ready to flash.

I can't really recommend a modem as they act completely different with your area/phone.
The only suggestion I can make is to use one from your carrier (AT&T). But it doesn't mean another one won't work better.
OK. I'll give that a shot and post the results in a few minutes.
Yeah I've used the IMEI injection tool to full effect. I have full data back. Using any other method to try to fix it would be just plain stupid. There is nothing else to test.

Did you get all the missing files back in your EFS folder?
Maybe I messed up somewhere. I don't have my full data or service back yet. I'm trying a few different modems to see what that does. It really doesn't matter if I get this fixed or not. I've already got a replacement on the way. I was just hoping that it could help somebody else out and I kinda like fixing things. The 2 modems I've tried so far aren't having any better results. I've got a couple more to try.
Would it be worth a try to redo the entire QPST, QCN Generator process?
I received my new Galaxy S3 today. That was Fast!! Lol Anyways, my research proved to be right. There's more going on than meets the eye when you loose and restore your IMEI. The original phone lost signal and would hardly ever connect to HSPA, only UMTS. The replacement phone automatically connected to HSPA as soon as I had it setup. I read on here somewhere that a lot of people were having the same problem when they re-injected their IMEI. I used the SGS3 QCN GEnerator app and still couldn't get good data connection. Actually I hardly had any connection at all. It would hardly pic up incoming calls and texts were sometimes an hour or more behind coming in. Flashing different modems didn't help either.
I'm going to do the proper backups this time before doing any flashing and if I have any more problems of this nature I'll have a good backup to fall back on.
