[Q] COMPLETE wipe not using CWM / .md5 ROM files

I have figured out that there is something wrong with my phone only when I have CWM5/6 flashed. So this leads me to believe that I need to clean out anything at all that is being left behind after certain flashes. (I get past my unbootable pixelated screen with one ROM that uses the original recovery)
So my question is how can I totally obliterate any and all files left behind or that were damaged by something from a custom flashed ROM?
On top of this question, I am wondering what ROMs are out there in the .tar.md5 file format so that I could use Download Mode to flash another ROM and at least have a working phone??
I find all the ROMs available but only in .zip format.

Sammy firmwares and use Odin.

Return phone to LITERAL factory state
I guess I should have been more clear.
What I mean that I would like to do, is to wipe out ANYTHING on the phone. Completely blank it as if it just rolled off the line. Then install the entire hidden partitions that samsung would do plus then add a new firmware.
The reason is that I cannot use CWM6 and my phone is an expensive paper weight right now. The problem arises from the fact that there has only been one ROM that actually worked for me from the beginning. That is the Bio360, and well originally the factory setup. Since I cannot use CWM and cannot flash a zip which Bio360 comes in. I have no way to enjoy the ROM or my phone for that matter. I have spent about a 100 hours flashing in all sorts of order and arrangements of kernels, ROMS and recovery files using every odin program I could find. Plus I have done about an equal amount of searching in between trying to figure out what has caused the issue. However, since my issue is localized then I would like to return my phone to LITERAL factory state.
Is it possible to format EVERYTHING and rewrite all of the necessary files? THAT would be a complete wipe by my definition.
Thanks for any help people.

I repeat Sammy firmwares had the stock files for you to flash via Odin. It is what you are asking for. Flash one of those roms then do a factory reset or format all partitions. Should be all nice and clean.

Take a backup of \efs before attempting to format everything.

Thanks for the reply. I already have all of the stock firmwares, but the thing is that that only flashes the actual software that a user uses daily. There is still boot software, recovery files and others within the hidden partition. A bit like a laptop keeps a partition or seperate small hard drive specifically just for a recovery and wipe clean of everything.
I was hoping that perhaps there is a possibility of startin with a clean slate, then re-writing all pertinent information back into the device, then putting the stock ROM etc back.
Again, the reason that I was thinking this would be my last hope is that everytime I use the CWM or anything other than a single ICS with a particular order of flashing the Cranium kernel without Auto-Reboot and then using the NAND Erase All and the other two checked can I get a ROM to work. The challenge is that now after I have got the phone back up and running without the CWM and with ICS is that it will not read a SIM card. I was thinking it was a hardware issue until after another 10 hours of trying various arrangements of flashable files, I finally got the device to not only boot into ICS, but after leaving it for 6 hours I 'awoke' it and it had loaded all the files and I got past the, black screen with pull down menu. I finally had a ROM that worked again even after my green and red pixelated screen issue. That leads me to believe again that it must be a software issue again. Not a hardware.
Thus leading me to think about any other options to literally start the device from scratch. Boot loading files, hidden files, etc etc. Literally EVERYTHING.

Excuse me, this might be a silly question, but as I've read no mention of it: Have you tried KIES?
Many a borked phone has been saved by an emergency recovery through KIES, or so I've been lead to believe. Perhaps it can help you in some way?
Seeing how you're the only one reporting this problem it seems far more likely to be a hardware issue. Maybe your internal drive is damaged? But I do hope I'm wrong in that regard. Anyway, if you haven't already, give KIES a try. It seems impossible to make things worse than they already are.
Good luck!
PS: You could also try the ICS-Leak, as it's a one-click executable containing bootloaders. Might fix whatever's messed up...?

I borked my Glide trying different ROMs a little while back and Kies is what brought it back to life. There is an option for firmware updates right below the emergency recovery option that asks you for the model and serial number of your phone. Takes a while but I watched it repartition and flash the hidden partition during the process. Brought the software back to out of the box. HTH.

I have the freeze problem, i try a lot of think (kies doesnt even start to flash), maybe is because the storage from rogers is only 4gb and the rom try to access like a 8gb storage, i dont know, when i flash GB, in the recovery menu, i see a meesage that cant access something. I hope someone can help us. Only ICS works, but, without root or any custom recovery.
I think that it need a clean install, atotal wipe.
THe Kies Give me this error, so i cant try if that can fix the problems

Lost IMEI, service, etc, issues - working on a fix. Need some input

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.
Sent from my SGH-T889 using Tapatalk 2

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.

Im having the same issues with no service. I have a t889 and a original sim card which was cut to microsim form. I had no trouble getting service. I rooted successfully and still had service. 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 feel like I followed all the appropriate steps to flash the room.

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)

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)

[Q] I am willing to be a test subject for I747 with IMEI, S/N issues

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.

[Q] Wifi/4g problems

I rooted my SGH-I317 awhile ago using galaxynote2root method. I have CWM recovery v6.0.1.4. I have flashed multiple roms including JellyThunder, Diaphanes and now I'm running Clean Rom.
I dont believe it's rom related because its happened on multiple roms but my problem started on Diaphanes and has continued on Clean Rom. When I am connected to wifi I am almost always not in service and I cannot send or receive messages. I know that I am in an area where I usually get excellent service so I'm not sure what is causing this problem.
I am still learning but I've come a long way thanks to some of you guys and any help would be awesome!

Have you done a full device wipe and restore to stock at any point to test ?
The symptoms you describe sound like something is missing. ..
It's too early to assume a hardware issue. ..
And a stock rom restore that includes the files known to function properly would be a good idea.
I suggest a full wipe, and an Odin restore of a rooted stock build. ...then report the findings. ..g

Could you point me in the right direction for such tasks?
All I found was Imnuts guide for such a thing but that is for SGH-I605 I believe.

So maybe my brain was malfunctioning...
Are you saying that I just need to flash a stock rom as I found here...http://forum.xda-developers.com/showthread.php?t=1986556
I thought you meant back to an unrooted version but then I reread it.
I always do a full wipe when I flash roms, so I'd just do that like normal?

What Modem you running? You might not have to flash back to stock.
Try flashing a different modem like the MC3, thats the latest one

I've never messed with my modem so I'd assume its as its always been. Can you link me to it? Is it the same as flashing a rom? Does it matter what rom im on?
Edit: I believe I found the download for mc3. So I just dl, reboot to recovery and flash it?

Yes, just reboot to recovery and flash it. There have been some significant improvements for some people after they upgraded to the newest modem. My data speeds over LTE almost doubled after the update.
Hope you get it working.

Very sorry for the late response ...
The thread link you posted is very old ....as we have much newer versions of rooted stock roms.
The latest is UCAMC3....and is available in the development section in several different configurations.
In an attempt to simplify the return to stock, look at the web site in the link you posted. "Scottsroms.com" is found in the developers signature line.
The site contains a rooted, deodexed stock rom that is flashable from recovery, and will produce the desired results while side stepping the need to use Odin.
Simply download the rom to your SD card, then boot to your recovery.
Wipe data/factory reset the device, and flash the new build.
Your original radio image will remain untouched, and once booted, the device will be clean and ready to be set the way you wish.
Ultimately, a simple fresh start is the logical next step....g

You are likely missing the correct APN settings. ..
Not all roms contain the pre-loaded configuration. ..
Check them in your network settings and enter then save the correct entries. ..
The APN lists can be found in the development section. ...g

New Modem...
Alright guys I tried to take the easy way out and simply flashed the CM3 modem. It has failed me. I've been on it for a few days now and run in to the same problems and maybe even worse.
I just flashed the CA4 modem to try that out (mainly because I have to go to work and dont have time to try a permanent fix right now), so I'll see how it goes. Other than that I believe I will be hitting up scottsrom.com and doing what you mentioned to side step a few of the steps for returning to stock.
I do have 1 question.....I'm on Clean Rom 4.8 and I am aware that there is an updated 4.9. Does it come with a modem? Even if not is it possible that updating would help my problem?
I appreciate the help.

4.9 does not contain a modem...
None of the roms do...with the exception of stock Odin builds...
Seriously. ..I would consider an Odin restore to stock...
You'll get all of the needed files. ..and the issues may resolve. ...g

Constant Rebooting

So my friends Boss' son tried to be all "l33t h4x3r" and mess with his S6(sm-g920p). First he ruined his EFS section of the phone, the Baseband is Unknown, no IMEI number, Software Version is Unknown, and his radio wasn't working. I think he then tried to do some crazy **** in ODIN, "No Clue he doesn't remember". Well i've never ran into a constant reboot issue with any Android phones i've owned. I've had bootloops but this is throwing me for a loop. I've tried:
Loading TWRP wiping everything and trying a Custom ROM
Using Odin to Recover back to Stock
Honestly im not sure whats up anymore or if his phone is even fixable at this time.

Hi, you certainly have a challenge there. It sounds like you need to restore both the partitions and the stock OS.
If the phone is a 32 GB model, please see the whole thread at http://forum.xda-developers.com/sprint-galaxy-s6/help/operating-smg920p-t3263325
There is a PIT file linked at post 16, instructions for using it at post 22. Also a link for the latest stock TAR file.
Again, this would be for 32 GB model, but you want to flash first the PIT and then the TAR.

I think I may have done that already too but I'll look again once in home and see if maybe I did it in the wrong order. Thanks for the quick reply friend. ?

Well i did as instructed but Baseband is still unknown and it is still rebooting over and over :/

If he messed up the efs partition, like it's empty, without a backup. I'm pretty sure the phone is done.

I recommend he brings it to Sprint, after they "diagnose" it and declear its broken they should be able to replace it. Just make sure its as close to stock as possible that way it does not seem rooted.

That is about the only option left. There are other options to restore the efs (pretty much rebuild it from scratch) but that is not something an every day user can do. I had an efs issue on my S4. I was tinkering with things I shouldn't have, forget exactly what I was doing, it was on T-Mobile so I think I was trying to remove the data cap (was on prepaid). Was pretty much in the same boat as OP but was able to completely from scratch rebuild the stuff that belongs in the efs directory. Some stuff I never restored but didn't seem to affect the device.

This was many many years ago. What saved me was the fact that Notepad++ keeps a copy of the file you have open even when you close the program. I just had to remember what things needed to be reverted back and the edits undone. I guess I didn't really rebuild it from scratch lol.

Yeah sadly I have no idea how the efs is populated. The second instance I get a new phone, dd is done on the efs partition and created into a .img file.

Koop's firmware didn't work with my phone either. This version of it fixed mine for some reason. Try flashing it to yours
mediafire.com/download/c55xaeb7geq0i2d/G920PVPU3BOJ7_G920PSPT3BOJ7_SPR.zip

Now i got same issue i accidently restored efs and ah man ive tried every thing it reboots after 2 or 3 mins no matter what rom back up i have and i have efs and radio with all my back ups ive restored it also no luck. Guess im going to the sprint store tomorrow even after i flashed stock 6.0.1 i can get to about half way through wifi setup before it reboots no matter what 2-3 minutes phone reboots unless in twrp

Still no luck becareful and dont try to restore efs i suppose in twrp. Your phone may never stop rebooting ive flashed 2 different 6.0.1 builds one was the revo other was from sammobil both @koop1955 has them PB6 6.0.1 odin doesnt fix this.

YOYOYO
Well wtf or omg it completely died left it for a day. Now its working so far it hasnt rebooted in 30 mins LOL but dude sucks going to a phone with kitkat after using marshmallow and one of the fastest phones made for awhile. I did pull the sim card out and try it in a old boost maybe that reset something idk its working though.My problems were Rebooting constantly after 2-3 mins no matter what rom i had even stock.

BEcareful if u restore that efs. i backed up too but once in twrp. Now all i did was check restore efs by accident just tried restoring a renegade rom system,boot, and data. Tell you what i wont be rushing through crap and am fine with stock for awhile. Probably will still take the replacement when it comes its white the black one i got is too blue.

Hey needless to say im researching full partition backups did you use a app by wanam partitions back up and restore? Or just simple adb commands. Last used adb on a moto e 2nd with success on unlocking. Once i got a new harddrive haven't needed it.

Theres similar issues happening on sprint note 5s as well and has a couple threads currently speaking about this problem. Strange strange. It happened to me after updating to mm and then rooting.

Well i did try the note rom right before and when i did hit restore efs it after wiping system data boot from moar MM rom phone rebooted for days then after few resets and odin flashes i let it die then a day later it worked.

Correct but have always preferred the 925p roms.

Well i helped another with the rebooting issue on any rom.
He tried everything then but let it die after battery died plug it in and bingo his worked to
IF CONSTANT REBOOTING.
LET THE BATTERY COMPLETLY DRAIN.
AFTER FLASHING STOCK.
