[SM-G550T1] [FIXED] Phones bricked, flashed stock and now cant get any service. - Samsung Galaxy On5 Questions & Answers

I got an error saying Unfortunately context service stopped working. I couldn't click anything so i restarted my phone. Got stuck on a samsung logo loop. Used odin to restore a stock firmware that i downloaded from here. https://forum.xda-developers.com/sa...on5s-sm-g550t-sm-g550t1-stuck-custom-t3647988 . But now i get a "No SIM card l no network connection" when the screen is locked. Under SIM status everything is "not available", and under IMEI everything is unknown.
Edit: I took 2 steps then it worked. not sure if the first one helped.
1) Deleted my EFS file by going to twrp > mount >tick efs> advanced file manager> then delete the whole folder then reboot. (this didnt fix my problem)
2) go to odin use the files from the link above and only used the CP file. REBOOT, FIXED.
Can I delete this post or should I leave it up thank you!

Please leave it up

Help - This morning Moto X Play showing "Start Up Failed"

My Sons Moto X Play (UK sim free XT1562) this morning was showing a bootloader screen with "Start Up Failed" then "Your device didnt start up successfully. Use the Software Repair Assistamt on computer to repair your device". Then further down it says "hab check failed for boot / failed to verify hab image boot / failed to validate boot image". I'm guessing an update occured overnight which failed somehow?
Anyway, found a copy of the image file "X_Play_UK_Retail_XT1562_LPD23.118-10_CFC.xml.zip" and popped it on a SD card. Started boot loader, changed to recovery mode (stock UPD23.118-10), choose "apply update from sdcard" but get the message "Internal and external memory cannot be mounted". Trying it again gives "E:error opening /sdcard: Permission denied". Tried a wipe data/factory reset and wipe cache then repeat, but get the same messages.
I'm at a bit of a loss now. Any help would be much appreciated. Thanks
I would flash stock rom with RSDLite from the computer. If you dont want it to wipe everything make sure to edit the flashfile.xml and servicefile.xml and remove <step operation="erase" partition="userdata"/> and <step operation="getvar" var="max-sparse-size"/>
You will lose root and custom recovery after that though.
This message appears to me once and I reflashed with RSDLite, and until now, everything is ok
Thanks guys. Couldn't get RSDLite to recognise the phone though.
Then noticed that the image I'd downloaded was an older version (5.1.1) of android. Managed to find a new 6.0.1 version here. Still not working with flash from SDcard, but got reading about ADB, installed it and flashed each part of the rom seperately and now it works. Hooray!
Got another problem now - the phone is insisting on using a google account previously used on the phone. I know my sons email address and password which I verified works on the PC, but the phone just loops round and asks for it again each time I enter it. Doesn't seem to be an option to skip for now either - very weird!

Make sure to install the moto x play drivers prior to opening RSDLite. You also have to be in download mode in the recovery options.
https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/88481
Clearly your rom has a problem explaining why the email security loops unless you arent connected to internet...
Did install the moto drivers when I tried RSDLite but no good. Anyway, that's not a problem now since I've got firmware on the phone and it now boots.
The issue with it not accepting the password for the google account has probably been made worse by me. In my frustration, I changed the google password. I've now read that after you do this, you have to wait 72 hours before you can re-auth a phone with that account. Shame. Will now wait and see what happens after that.
Thanks again
Update - after waiting the 72 hours, the phone has now accepted the new google account password so we're back in business.
My son was very happy to get his phone back.
Thanks all

Failed to mount EFS Invalid argument & Dm-Verity verification failed.

I recently purchased a Galaxy Note 4 on EBAY running stock firmware and activated it on my cellular network with no issues. The phone works fine i.e calls, texts, other functions. I am however faced with a Wi-Fi issue. If I ever power off my phone and turn it back on, the Wi-Fi fails to automatically connect. I have to manually reconnect and every time I do so I get a message that says" the phone in in factory mode and wifi is now turning off, change to user mode, "This message does not stay for too long on the screen. I used ODIN to redo the stock firmware. It was during this process that i noticed the messages (mention below) in recovery mode.
E: failed to mount /efs (invalid argument)
dm-verity verification failed...
I still went ahead and re flashed the stock firmware assuming it would fix all issues, but it did not. Not sure if this phone was rooted at sometime or not. Any help would be much appreciated.
I have used ODIN to flash stick US Cellualr ROM, but problem still exists.

Did you have a back uo of your efs files? That contains your imei which if its corrupted is very hard to revive.... and by the sounds of it yours could be corrupted.
Can you get into the phone now will it boot?

I am able to use the phone and have also used it on the cellular network, was wondering how I could resolve the mentioned issue. The phone must have been rooted at some point and it wasn't done by me, so I do not have a back up of the efs folder.

As long as the phone works thats good. Just boot to twrp and back up efs folder just incase. As for your issue i would of thought flashing stock would of fixed it. Have you wiped dalvik and cache?
Try to Make a full backup then flash a stock firmware with pit file of your exactly device

Samsung Galaxy J5 Prime IMEI null with no EFS backup

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!

N910F Stock firmware corrupted.

My note 4, randomly crashed, running completely stock.
Began bootlooping and hasn't stopped.
Have downloaded firmwares from Samsung-Firmware . org, as SamMobile will literally not allow me to download anything for free??
No firmware has worked on the device, Have tried numerous PDA versions as I am unsure which the phone originally is.
The first firmware gave the error "dm-verity verification failed" in the recovery menu.
Have wiped cache and data.
Note: This is actually the second N910F which had corrupted itself and stopped working.
Help! :angel:
Do you want to recover some data from it?
If Not than you can try factory reset from Recovery menu.
Other than that it might be memory corrupted or your battery.
Try to change the battery.

New battery: Allowed the phone to boot past the first "Samsung Note 4" screen to : "Samsung" logo, but the phone made a loud beep/screech.
If you want to reflash the Stock ROM search for a version on https://updato.com
I just reflashed mine (g910f) even twice as I had an Infini-Boot, too. After cleaning Dalvik/Cache and formatting data, taking out the battery, after some time it suddenly displayed that it's going to setup apps and it works since then ...
So maybe just be patient.

to get the latest stock rom for your device, free and fast
look what you have to do:
download this (windows ) application and install it on your windows pc.
This is the aplication that will allow you to search and download the latest stock rom for your phone.
It connect to Samsung servers and in very little time you will have a new stock rom on your pc.
choose samfirm 3.06
extract it on a folder on your PC and run samfirm.exe
in the opening menu type
SM-N910F(or T/V/W etc your phones model)
REGION..... xxx (your region code)
these 2 you can find in a sticker under your battery if you open the phone and take off the battery
tick '' BINARY NATURE''
(If you dont tick BINARY...'' you will get the whole stock rom in one file xxxx.tar.md5 to flash it in the oding using the AP tab)
CHECK UPDATES>DOWNLOAD
THIS WAY YOU WILL GET THE LATEST STOCK ROM FOR YOUR PHONE/REGION
Binary nature means the rom split in 4 files
1. BL- bootloader
2.AP - rom
3. CP - modem
4. CSC - Customer support code(region/country)
This is what a stock rom is consist of
this kind of rom is also called REPAIR ROM, because you can use it to repair your phone.
If you look in odin you will find exactly these 4 entries.
So you can put each in the appropriate box and flash them all and so have a stock rom.
push start
Wait until rom flashes and phone reboots.
Hopefully it will solve your problem and everything will go as we all wish to.
BUT, from what you are describing, i am afraid for 2 things:
1. Your battery is almost dead, thats the good scenario .
With 20 $ you will solve it.
So new battery, new rom> problem solved, or
2. You are starting to have the emmc failure on your phone.
Thats a tough one.
Lets hope its not the case.
Just in case

SM-J730G(M): No idea what I did to the OS

Hey! Newbie here in need of some help... (sorry for the poor formatting)
So about two years ago i got a J7 Pro (box says SM-J730G/DS, which is important for later) from my carrier (IUS) (MX), and I tried to root it. Apparently it didn't go well or something, I honestly have no recollection, and then because of external forces I had to change to iPhone.
The only thing I remeber before I stopped using it is that the settings app was kinda messed up (eg. there were two "Battery" settings, there was a new option called "Service provider" which had the options "KT twophone service", which apparently is Korean, and "My Wi-Fi home settings", etc.) Also, I got a "Processing failed" error message when wanting to check for updates.
Now yesterday I decided to unearth it again and of couse everything was the same, so I investigated how to return to stock firmware. The Smart Switch option isn't possible anymore; the only viable way (atm) for me is via Odin. The phone also somehow does not boot into recovery mode by Volume Down + Power.
I downloaded the firmware, and this is where everything gets messy. It seems the firmware I had flashed previously was SM-J730GM, which is still the only one I can find for my carrier and region. It is the firmware too that I flashed today (J730GMUBU2AQI3 and J730GMUBU2AQF3) through Odin, however I was not able to flash the BL, CP and CSC, because I would get a myriad of errors (one run I would get "repartition operation failed", on another, "cm.bin fail", or fail on the "set .pit file", and so on).
Remember when I said the box info was important? Yeah, the app Phone Info *Samsung* says both the bootloader and the broadband version are J730GUBU1AQF3, not J730GMUBU2AQF3. However, Sammobile says that for my region/carrier (MX/IUS), it is GM, not G. The back of my phone, however, says J730G/DS
I am at a loss. I read that one possibility is to use the Re-partition and NAND Erase options in Odin, but since I don't know whether my phone is J730G or J730GM, and I don't have a way to backup my EFS folder, I don't feel like doing that.
Could someone please explain to me what I can do to fix this?

Again, I'm really sorry for the formatting.

1. Try heimdall instead of odin
2. Try with pc, adb fastboot wipe commands

Okay so,
1. What is the current state of your phone(is it bricked or working)?
2. What version of Android do you have( 7.0 Nougat ) or ?
If your phone is NOT bricked, I recommend first to go to developer settings and do OEM unlock
(you can enable developer settings by tapping the field Build Number fast multiple times in About phone information)
then, you can download stock firmware for J730G( not J730GM) and it doesn't have to be from your carrier or country.
After that, you can either use your stock rom or flash recovery and then flash custom ROM.
