Hey everyone,
So, I'm pretty new to Android having had the past two iterations of the Nexus 7 and decided to take the leap from an iPhone (which I had jailbroken) to a Samsung Galaxy S4 GT-I9505 LTE, which I bought unlocked and outright.
I ran stock TouchWiz for a while and then wanted to play, so installed FoxHound 3.2. This worked fine for some time, but then I started getting random reboots which seemed to coincide with listening to music on the device. After a while the reboots suddenly became more regular and it got so I couldn't even open WhatsApp without it either restarting or going into a bootloop. Usually, if it went into a bootloop and I tried starting the phone straight away it would fail, but if I left it off for some time it would start up okay, only to reboot again later if I used it for anything. I also noticed the battery draining quickly.
I tried flashing the device with various other ROMs - PACMan, Google AOKP, etc. - but got the same issue. Many times, the system would crash just when I first started to setup the phone. I finally determined the reason it was crashing at the initial startup was that it was when WiFi was being enabled. So, I ended up following a fruitless several hours of attempting to fix the WiFi using files provided on this page: http://forum.xda-developers.com/showthread.php?t=2192025. I tried XXUDMH8, XXUEMJ7 and XXUEMK8 all to no avail - I installed both the firmware and the WiFi fix files using Odin and thought I had it cracked, only for my phone to eventually reboot again whilst WiFi was not even enabled - it did take a bit longer this time though, admittedly, but it still rebooted and went into a bootloop.
So, I finally followed this page: http://galaxys4root.com/galaxy-s4-tutorials/how-to-unroot-galaxy-s4-and-remove-root-completely/ to completely return my device to stock TouchWiz, but still no joy.
I have tried factory resetting the device and wiping all cache from the stock recovery and from Philz CWM (which I had while using the custom ROMs), but this does nothing.
I tried connecting my device to Kies now that I have the stock TouchWiz ROM back on the device, but it is now rebooting even more frequently and I can't get in long enough to run the emergency firmware recovery. It used to stay up longer (sometimes indefinitely) when connected to the PC via the Samsung factory cable or to a power supply with the Samsung charger, but now it is even rebooting when plugged in.
I am extremely worried that my device that cost me nearly £600 a few months ago is bricked for good. I did (understandably) think that returning it to default would've resolved the issue, but even this has failed.
Is there ANYTHING else I can try that I have not already........?

Hi and thanks for your reply,
I can boot into download mode - one of the only things I can do! - and it says 0x1 under KNOX WARRANTY VOID, so yes it is showing Knox void.
Just in case you need it, the full information shown on the screen in download mode is as follows:
ODIN MODE
PRODUCT NAME: GT-I9505
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
KNOX KERNEL LOCK: 0x0
KNOX WARRANTY VOID: 0x1
CSB-CONFIG-LSB: 0x30
WRITE PROTECTION: Enable
eMMC BURST MODE enabled
Thanks again..

Hey Repulsa,
Thanks again. Unfortunately, this is what I did. I signed up at samfirmware and downloaded the file: I9505XXUEMK8_I9505BTUEMK5_BTU.zip
The only thing I did different was that I used Odin 3.07 and flashed using the PDA option, but I'm presuming this is the same thing..? After the bootloop, I went into recovery and factory reset, but still the bootloop occurs.
I have since managed to get into my phone after leaving it off for a couple of hours again and looking through the settings it says I have "Samsung" as the secure boot status and "Official" as the device status. The build number is showing up as JSS15J.I9505XXUEMK8 on Android 4.3.
Should I try anything else that you can think of?
Thanks again for the reply.

Yes, I'm afraid it does, and I have already done the wipe cache and factory reset, but no joy. I did it again anyway and on reboot it went back into the bootloop again, I'm afraid..

Ah FFS. My battery serial does start with BD and I was wondering if it was a battery issue, but didn't want to replace it if the fault was wider spread. I guess I may have to try this then..
I'm just flashing to MJ7 right now, but if it reboots again I will see about a new battery from where I bought it on Monday
And, as I forgot to say in the last post: thanks for your reply. If this fixes it, much kudos, my friend..
Yep. The flashing of MJ7 did not work. Maybe my battery is a dud as it went straight back into a bootloop at the Samsung logo.
Carphone Warehouse visit on Monday methinks..

you can get passed the samsung logo if you boot while your charger is connected to the phone, the battery might swell as well or is already bigger then it originally was
My phone has been randomly shutting down over the past couple of days and the only way I can get it to boot is to connect a charger/cable to pc. I've tried different ROMs and returning to stock. No joy.
I guess my battery could well be the problem

My phone has randomly started shutting down over the past couple of days and the only way I can get it to boot is to connect charger/cable to pc. When it dies, it also loses all of my wifi passwords. It's a bit of a head scratcher. Any help appreciated
Definately the battery, dude
I was experiencing the same problems, and I observed that the battery swollen. So I replaced it and now the phone is functioning properly. Do not wait for the battery to modify its volume because you are risking to put pressure on the display and crack it. Beware.
Was, indeed, the battery
Hey everyone,
Just to let you know that I went back to Phones4u with the receipt from September (when I bought the new phone) and they filled out a form to request a new battery from Samsung and replaced mine their and then in the shop with a new battery from another Samsung Galaxy S4.
My old battery did, indeed, have a serial number that started with BD and the new one starts with AA so hopefully I am now sorted.
Massive thanks to everyone who replied and hopefully this thread will save someone else the time and lost data that flashing ROMs can incur.
Cheers,
A very happy Steve :laugh:
Note 4 Stuck in Boot Loop - Help
I have a Note 4 SM-N910F, never been rooted, stock rom upgraded to 5.1.1 back in October, working fine until yesterday when it got stuck in a Boot loop.
Not sure what caused it but before it got stuck I was messing around with Google Photos which was running a bit slow.
Also I put it on the Qi Charger just before the loop started. It has an aftermarket Fone charger stuck to the battery. I’ve had this and the Qi Charger for 6mths with no problems before now.
It gets to the Samsung page waits a couple of seconds then boots again.
Here’s what I’ve tried - unsuccessfully - to fix the boot loop:
1: recovery mode.
I can get the little recovery text to appear in the top left but after a few seconds it boots again.
2: volume down, home
This gets me to the screen with up/down for continue/cancel.
This is the _only_ screen I can get to stay up without rebooting. It sits there waiting for input.
- Cancel, causes restart, of course, but back into the bootloop
3: Mashing on power button. Banging it, wiggling it, blowing on it.
I read somewhere this could cause a boot loop, but I doubt it is my case because
a. I’ve never had problems with the power button before
b: When I take out the battery and put it back in, it does NOT turn on. If I do the same holding the power button, it powers into the boot loop. So if the button were jammed on I would expect it to never remain off with the battery in.
3: flashing stock rom
I’m not 100% sure what build I had before. I know it was stock 5.1.1 OTA, and I’m pretty sure it was unlocked (my wife bought the phone and i inserted my old sim, but she may have bought it from my carrier and can’t remember)
So anyway I tried all three versions of TPH (unlocked) 5.1.1 from Sammobile.
Installed Odin 3.10.7 and flashed them.
It reboots to recovery but immediately boot loops again.
I doubt its to do with the version of the rom anyway since the symptoms are identical after flashing. Only now the boot loop always shows the little ‘recovery booting...’ text in the top left.
Here’s what I have NOT tried but am thinking about:
A: Re-partition option in Odin
B: Nand Erase All option in Odin
C: Buying a new battery.
On A/B: as far as I can tell what I have done so far should have left the data intact. I’m prepared to wipe all my data if it fixes my phone (no lectures about backups please!) and I’m tempted to do one of these on the off chance that the problem is caused by data or the “disk" problems.
But I don’t want to brick it. Can someone recommend how likely these are to help
And what they actually do?
(Please refrain from responses I see elsewhere like “this will brick your phone if you don’t know what you’re doing”. I don’t know what I’m doing, thats why I’m asking - just the facts please)
On C: the battery seems ok in that the power is solid even after not being plugged in for a long time, but since it was on the Qi Charger with that aftermarket thing stuck to it when it happened, I’m suspicious. Can any one say if this is a likely cause?
If so, it might be worth waiting till I get a new batter before doing A or B (can I wait days for Amazon!?)
[UPDATE] Got a new (genuine) battery at a local electronics store. No dice. Same problem, so it's not the battery. Shall I go ahead and re-partition.
[UPDATE] Got a PIT file from another forum, and flashed again with re-partition checked and PIT loaded. same results.
Is Nand-rease worth trying?
The phone is still under warranty so maybe I can return it.
But in that case I want to erase what's on it first.
thanks for any help

I don't think that the Samsung service center will accept cuz u have unofficiall custom
Simple Go to ur any nearby SOFTWARE ENGINEER may be he will help u out
Even I had the same problem with my NOTE 4 EDGE
Try downloading and flashing any "COJ5" build of 5.1.1 from sammobile. Samsung has recently issued a new update "COJ5" it basically locks down the bootloader and will not allow the device to run any previous builds.....Maybe your phone updated to COJ5 in the background and then it started messing around because the phone is rooted. Flashing "COJ5" will lock your bootloader and you will not be able to flash 4.4.4 or 5.0.2 but there is nothing to lose when your phone is already pretty much dead?.....ORRR if this is not a software issue then it could be related to hardware maybe the memory of your phone is done. I am not an expert on this but this is just an advice.....i have told you what will happen if u flash coj5 build now its up to you to decide. I would suggest you wait and wait if you are lucky to get a response from an expert and do what they say .......if not then give this a try!
**EDIT** another idea....First flash a custom recovery such as TWRP....see if it lets you boot into recovery and if it does then perform all sorts of formats.....and factory resets in there see if it works....if its still rebooting after format then flash the coj5 build of 5.1.1....note that you "MUST" format it with TWRP first and then check if its working because once you have coj5...it might not let you flash custom recoveries.

You can flash TWRP through ODIN while on COJ5 bootloader. It's locked but you still can flash recoveries and kernel and 5.1.1 ROMS
I am very interested in this thread. I have the EXACT same problem as you have after installing SimplRom, which was a ROM prior to COJ5. It could indeed be that our bootloaders are locked now?
I am using the N910F and just like you, installing any ROM/Custom Recovery/Bootloader/Kernel doesn't help. Perhaps installing a COJ5 ROM might help. I will give that a try, but I've recently used Kies to install the latest official firmware, but it didn't fix the issue.
I will report back here and we'll work on this together to make our phones work again!

Thanks to you and dork97 for the ideas. First some notes:
- I have never flashed a custom ROM, nor ROOTed this Note 4. The recent upgrade to 5.1.1 was official.
the first upgrade to 5.0.1 was automatic and after that I turned off automatic upgrades and upgraded to 5.1.1. manually. So I dont think it was an upgrade that caused it and it certainly was NOT a custom ROM or ROOT. I was doing nothing at all when the boot loop started.
- I'm not sure what ROM I had, but when I went looking for the available Portugal unlocked ROM, which _should_ be what I had, the latest were CJ03 (3, not 5) and before that CH03, CI03. Presumably I had one of those (my last update was October, so probably CH03).
I have tried all 3 of these, but the symptoms are the same.
I'm tempted to try the TWRP option - but would like some more details on what is and what it does, or what problem I might have that it would fix.
However I am probably still in time for a warranty repair - especially since I didnt actually do anything for this to happen. I would like to avoid losing that chance.
If I do take it in for warranty, I'd like to wipe the memory first though. How can I do that?
Finally can anyone actually tell me if the NAND ERASE is likely to help? How does flashing TWRP compare?
I get the feeling in fact, that I have a hardware problem. Especially given there were not software system changes around the time it happened, and given that it loops while trying to boot into recovery mode. In fact the only mode that doesnt constantly cycle is download mode. (Even holding the power button in dl mode does nothing which makes me suspect that, but pulling the battery out and replacing it leaves it off until I press the power button so perhaps not)
Thanks for the replies so far. Any more ideas, details?

I have the exact same as you. I did install a custom recovery (multiple) and still get the bootloop. From my tries yesterday, I indeed also suspect it may be a hardware issue. Perhaps to do with the battery/charging port. When I have my device unplugged and try to start in recovery/normalboot, it does not have a bootloop but simply turns off (and then doesn't respond until I pull the battery out). I think a NAND erase wouldn't do anything as I've personally tried that already.
Have you prior (upto a week) before you got the issues had your phone in a moist environment (bathroom while showering for example). I got my problems a week after I accidentally left my phone in the bathroom and installed custom ROM (which was done earlier and had no issues).
I've read online that it may have caused oxidation on the inside and may need some cleaning/drying with alcohol.
I still hold hope that we just have a software issue as download mode is working fine (apart from the Power off not working unless we pull out the battery).
Anybody have any experience with oxidation on their phone? Perhaps have had a similar bootloop due to hardware failure?

Since you can get into download mode I'd flash firmware through ODIN again after verifying it's correct.
I'm seeing off the sammobile site for the 910F not all are the COJ5 locked bootloader.
Since you did update in Oct you may be on the COJ3. I'd try one of those and see if it works.
If it doesn't work and stops on the sboot.bin file then you have the COJ5

i am sorry i don't know any way to remove personal data other than doing it via recovery. There is an option of "nand erase" in odin it is used while flashing firmware and it wipes everything on the phone but i have never used it (and also don't know whether it can help you or not) ... Senior members kindly help us with this.
Any update to your situation?
very interested as I am in the same situation as you are. Download mode works, recovery+normal boot not. No matter what ROMs/recoveries I install
Same issue I think
I am also in the same situation, although I can enter the recovery mode - home power and volume up - I have tried the wipe cache and then factory wipe to no avail - I have also entered download mode and flashed the stock recovery and even though Odin says pass, it is still in a boot loop. Also when I go to the download screen it has a line saying knox warranty void 0x1(4) does this mean I have voided the warranty even though I only used Odin to flash stock recovery?
Did anyone found a solution
Did anyone ever found a solution to this problem I'm having the exact same issue on a note 4 smn910a
I have a slightly different issue with my Note 4 SM-N910G, wherein am not able to start the phone at all, it is completely dead, if i put the cell phone on charge then also there is no LED on the top but if i connect the device to the PC it does make the connected sound on the PC but Odin is still not able to recognize the device neither kies. I tried draining the power by removing the battery, connected the device to PC without battery and then inserting it but the same problem. Please suggest me any resolution for this dead body am carrying from past few weeks.
hi Op,
did you find any solution for this issue?
Hello all. This is advice to use as a very last resort if you are experiencing the recovery bootloop issue AND you don't have the emmc failure bug. I had the recovery reboot, sudden shutdown with no warning, etc. issue for the past two weeks. I tried everything on Google and Youtube to fix my problem with no success. I flashed multiple stock ROMS and recovery tars (stock and TWRP) via ODIN, but nothing worked. Oddly enough, I never received the emmc error that I have read about. Also, in the few times that my phone booted normally, I even loaded the Wakelock Power Manager app, set it to partial wakelock and my phone STILL continued to bootloop. As a last resort, I bought a new battery, but the reboot problems continued in Android 4.4.4 Kitkat, 6.0 Marshmallow, 7.1 Nougat and 8.1 Oreo ROMS. Well, here is what finally helped me to get my phone back operational. I had a backup ROM from a previous install and a TWRP flashable version of the same ROM on my SD card (in case the phone did not stay on for the full restore). I put the phone into a ziplock bag into a freezer for about 20 min. (thankfully this time TWRP stayed on long enough for me to do the following):
1) copy all the files I wanted to save from internal storage to a computer.
2) performed a full wipe (Dalvic, Cache, System, etc. Like when flashing a ROM, but this time also internal storage. Note: Please do not wipe both internal and SD card, as you may have a difficult time trying to load the ROM file back on the sd card (assuming you don't have a card reader).
3) After wiping, I was able to restore my stock ROM backup (or you can just flash the stock ROM).
I can't be 100% sure, but I think my wiping internal and then flashing the stock ROM finally did the trick. Since this morning, the phone has been pretty much back to as it was before. In either case, I'm sharing this with the hope that it helps someone else.

The device is untouched in terms of modifications since purchase, so unrooted stock rom. I can get into download mode, and occasionally, recovery mode. I wiped the cache as my first attempted fix - no change. Then did a factory reset - no change. I then thought I'd try loading twrp so I could flash a custom rom, but Odin was unable to flash it due to FRP Lock blocking it. I then downloaded the latest stock rom from sammobile, and was able to flash this via Odin. On first boot the device did start to load, and reached 10/19 in optimising the apps, before starting the boot loop again. I am kinda out of ideas now. Any help would be greatly appreciated.

Go into settings>developer's options and ENABLE OEM UNLOCK then
go into settings>general management>reset>factory data reset and
reset the phone.
Once you have done that the phone will work properly without rebooting
provided that you have successfully odin flashed the official samsung
G935F S7 Edge firmware prior to doing a factory data reset.
Good luck, have a great day!
Thanks for replying. Unfortunately I can't get into the phone at all. Only screen I have access to a recovery and downloader.
So I left the phone alone for a while and tried booting into safemode. This time it worked - sort of. It is asking me for a password, but I have never set one. I only ever set a pin and fingerprints. But since wiping everything that doesn't seem to apply anymore. What is the default password? I am referring to the phone password, rather than a google account obviously. I am not at that stage of the boot up.
Update: found the password (default_password), still boot looping on the optimising apps screen.
If you still can't get into the phone like the person above said, I would use Oden to reparation and reflash your stock rom. If it still gives you issues, I'd suspect hardware fault.

I have flashed stock rom (initially the version that matches my carrier, although my phone was bought sim free and unlocked, and then the version for unlocked phones (BTU in sammobile I think)) but it still just boot loops. The phone can remain in download mode as long as it wants, and previously, when it was asking for the password, it was able to remain on that screen indefinitely. I would have thought if it was a hardware problem the boot looping would happen regardless of the action on screen. Immediately after flashing the stock rom, it did start to load before ooting. Now it just boots immediately at the Samsung Logo.

Just to be clear, do you mean repartition here? I have not checked that option before, will try it.
Even without the PIT file. Flashing stock rom should have fixed you... which carrier do you have? If Verizon, they have a recovery assistant software that works in these situations. Or if not try "samsung kies". If all else fails I'd give Sammy a call.

I am in the UK, and my carrier is Three, although the phone was purchased sim free. I tried samsung kies (phone not compatible apparently), samsung switch (phone does not support initialization). I may have to call Samsung, but I purchased the phone on eBay, so no warranty (never doing that again!), so I guess it'll be expensive to get them to sort it. I've taken it to a phone repair shop this afternoon and the guy reckoned he could fix it based on what I said. We shall see. I don't have to pay unless he fixes it, so worth a shot.
You can wipe your phone by entering recovery. Default recovery has the wipe option.

Was the first thing I tried. Didn't help.
I got the bootloop thingy and was the cache, I wiped and the phone booted up

Hope all goes well, let us know if you get it sorted out.
Hi
Just curious...why do u say u don't have warranty just because u brought from eBay?
Surely it doesn't matter where u brought it and it still has warranty.
Have u tried contacting Samsung?

Pretty much all warranties (including Samsung - I checked) are contracts with the original purchaser only. Even if you have proof of purchase, you then need to match the records they have of the identity of the original purchaser. Whilst some manufacturers will be more lenient, others will follow the official policy strictly. Speaking from experience here.

For those perhaps in similar situation in the future, Samsung didn't care that it was purchased second hand, despite what the fine print says. They just looked at the serial number. In the course of trying my own repairs I flashed a custom rom, which of course tripped the knox warranty void bit. When I took it into the service centre they saw this and then wanted to charge £225 for an out of warranty repair. I refused at the time. I later called Samsung support and explained the situation (I said a phone repair shop must have done the flashing). Again on the phone I was told it would be an out of warranty repair, and this time I agreed. They collected my phone and returned it to me today however, with no invoice or mention of charges, so it looks like they just did the repair no questions asked.
I have the same issues, so far I'm getting by with flashing a stock rom with pit file and doing repartition and nand erase, normal cache/ factory reset doesn't help, it sometimes even boot loops while in twrp.
Somehow Odin flashing helps for a random amount of time, but it has thus far, crashed after a month, or a couple weeks since the last flash, etc. So far it's been my 5th boot loop event in the last 6 months
It sucks but as I got mine from another country (/win), didn't get the warranty ;( plus I tripped Knox by rooting.
sounds hardware related to me..
i had a friend with a note 4 who had similar problems it would hardly ever boot sometimes boot straight into download mode..
if by chance it did boot it would boot once the device was locked for a short time it would reboot and start over again bootlooping..
it was the emmc flash memory that was failing...
a workaround i found for this was the first thing i did when finally getting it to boot was install "Wake Lock - CPU Awake" and set it to never let the device sleep and to startup on boot...
this "fixed" it as long as your phone does not turn off... he had insurance though and sent it off and they sent him a new refirb
again this note 4 was untouched never rooted or anything

im having pretty much the exact same problem except ive been unsuccesful at flashing the stock firmware for my galaxy s7 active (SM-G891A). the active series isnt the most saute after, so finding the right firmware is alil more difficult. which im pretty sure is how i got into this situation! my question is what exacly does checking the "reparation" option do. i read to leave to leave it unchecked/unticked. maybe thats why ive been unsuccessful. and someone told me awhile ago not to fill in the "bt" box becuz i have a locked bootloader. this correct or no?
Hi everyone,
Google messed up ! I received the OTA for the 7.1.2 uptdate last thursday. After it my phone was unable to detect my SIM card, my IMEI number disappeared, neither base band.
The first thing i've tried is to get a new SIM card, with no result, then I tried a soft reset, an hard reset (factory reset+wipe data), and wiping the cache without any positive result either. I've contacted Google, the phone was from Google Store and my 1 year warranty expired on 25/03/17 (the update was installed on 05/04/17, exactly two week later), they refused to take it back, nor RMA, a shame! I think it will be the last Google phone I buy!
I've tried to flash the full factory image of 7.1.1. but nothing positive from it. I think the OTA corrupted my EFS data files but no idea on how to fix it. The thing is when i'm going to the bootloader, under barcodes menu i still find an IMEI number.
I don't know what to do now, I'm little bit desperate, if anyone have an advice here.:crying::crying:
Thank you in advance.

Hello...
Unless you have a TWRP EFS backup, there's not much you can do...
I already saw some people saying that a restore from someone else EFS backup solved the problem and their proper IMEI, etc were back. I never had the issue, so I can't confirm it really works.
Now you need to find someone who can give it to you.
Otherwise you can RMA...
Good luck...
Is there any personal info in the efs backup? I would be happy to help but am not going to jeopardize privacy...

Hello...
Since his IMEI disappeared, there must be infos about it somewhere in the EFS. I don't know what else...

I think giving someone a copy of your efs partition essentially gives them the information needed to clone your phone, so it's not something you would want to do for a stranger.

Several people have been able to recover from this by wiping both the EFS partitions, but because your bootloader is locked (and USB debugging probably not enabled), I don't believe there is any way forward.

Hi Guys
This is my first post on xda even after using these forums for years. But today I cant find a solution on here or anywhere for that fact, and was literally hoping that I've missed something somewhere.
So to start. I have a Samsung Galaxy J5 Prime (SM-G570F). The other day I was flashing a custom rom when something went wrong during the flashing process and left me with a bricked device. Now I did do a full backup before flashing as I've learned the hard way how important this is. During the flashing it also asked me for a full wipe and to backup the EFS. Even though I did do all the backups and wiped everything< I've ticked both boxes and proceeded with the installation. Everything seemed fine but on 99.9% it froze. Not wanting to do anything I left it until it rebooted the phone by itself, where I was greeted with the download/flash screen. Didn't even give the warning about installing custom software and asked to continue. It just booted straight to the download screen. Tried getting back into recovery only to be greeted with download screen. No matter what I did it just kept booting into download mode. So I then re-flashed TWRP. Getting into the recovery I was able to mount EFS, System, Data, etc. Bu all showed 0mb of 0mb available. I then went to restore everything only to find that the SD Card was also wiped by the process. Thinking that maybe the recovery isn't reading everything correctly, I found the SD Card empty in windows also. No call me names or whatever, (I know my own stupidity) but I never backed up my backups on my PC. So I just proceeded flashing stock firmware as to start from scratch. Everything went as planned until the device got reset by odin. I was greeted with a screen saying "installing system update", but as soon as it reach 32% it changes to "erasing" and then "error" with the "DRK Missing" error. Then it boots to recovery where an error message is saying "unable to mount: EFS (Device or Recourse busy). I cleared cache and did a factory reset and it booted the system (Though mount error still appears in recovery even in custom TWRP/CWM recoveries also). Now I have a 00000..... IMEI number and no network connection. I've spent the last week on the web trying to find a solution with no luck. I'm tired AF because I didn't sleep trying to solve this. I tried flashing stock and custom roms, recovery's, boot-loaders, modems. Tried different software's like Samsung Tool, IMEI repair tool, Strings of adb commands, xposed modules, apps, terminals, etc. I even flashed factory binaries with no luck as to how to change it back.
So in short.
My EFS got wiped.
I lost my IMEI.
I don't have any backups.
Been awake for a week searching for solutions with no luck.
So please if anyone knows of a way to change the IMEI, please help me. I know It's illegal to change IMEI (though not in my country). But I down't want to change it for all the wrong reasons. I just want to change it back to the original found on the back of the phone and on the box. This can't do any harm can it? Please I just want my phone back please!

If this problem is still open, then on Your Phone box is writen imei, or take battery out and under serial number there will be your imei, root your device and use IMEI changer grant root access and type your imei in it, after that reboot and your imei should pop up! I had same issue and this steps made my day! THIS WORKS ONLY ON YOUR IMEI, YOU CAN'T CRACK, STEAL IMEI By this method, don't believe those Dumb ****'s from YouTube!
May I help You!
