HELP! invalid IMEI and cannot boot to download mode - Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin

Hello
I restored factory/data reset on my grand duo gt-9082 and suddenly encountered the following problems
1. Both IMEI shows 'invalid' and the SIM Card in the phone when i did the reset doesn't work with the phone anymore.Unfortunately i do not have an efs backup
2.I cannot boot to download mode so i could use ODIN. voldown+menu+power boots to recovery, volup+menu+power also boots to recovery. I've tried all possible button combo including command/adb in windows no success.
No reliable service center around here, any help would be greatly appreciated.

Failed to mount /efs error

Hi all,
i've search and tried most of the methods on threads with similar issue but to no avail.
So i'm posting my situation here hoping someone with the expertise can help me.
My IMEI became null/null after flashing Criskelo rom. I had previously saved a copy of my efs.img on my PC.
When restoring my EFS backup, it says "/dev/block/mmcblk0p3: write error: No space left on device"
So i used Odin, flash a stock ROM with pit, bootloader, pda, phone and csc.
The flashing was successful with no errors but stuck samsung logo for as long as i can wait.
I then booted to stock recovery and notice it says "E: failed to mount /efs (invalid argument)"
so i did a wipe data/factory reset and wipe cache partition.
Reboot. Still stuck at Samsung logo.
I tried to sideload my efs.img but there is a "E: signature not verified" error
So i thought what the heck and flashed Chenglu's CWM via Odin. Phone successfully boot to CWM
i wiped data/factory reset, cache and dalvik. Reboot and still stuck at Samsung logo.
I then tried flashing CF-Autoroot, it was ok as well with no issues but stuck at Samsung logo again.
Rebooted back to CWM, Tried to mount efs, got an error saying error mounting efs
i flashed various stock rom via Odin, all process PASS with green but mostly stucked at samsung logo...
is my device soft bricked? or is my sd card is dead? or is my efs partition fried?
anyone kind enough to share his complete backup file? my country sells the n7105.
i bought the export n7100 instead so its kinda hard for me to find a friend with the same fone.
i have been flashing roms since the good old Galaxy S and this is the 1st time i cannot revive my phone from past experience...
bump for you, im facing the same error.
Hi mate, im not sure if this would work but have you tried the super wipe mod here http://forum.xda-developers.com/showthread.php?t=1925402.
worth a shot cant make it any worse.
also checkout this for a solution http://forum.xda-developers.com/sitesearch.php?q=E: signature not verified
Hi thanks... sadly links are down. will try the super wipe thing.
i remember doing the wipe in TWRP before flashing Criskelo.
i did get away with the signature thing. its easy. just turn it off in CWM.
i went to my local samsung service center and they rejected my phone as its considered "export" to them
did the super wipe.
Flash stock with Odin.
Still keep getting stuck at samsung logo on boot and recovery still shows : Error: Can't mount /efs
cant you restore it to factory settings and return it to where you bought it from.

mine is under warranty, so I could try to restore to stock rom which gets stuck at the samsung logo.
problem is that going into download mode shows this :
custom binary download : 12
Current binary : samsung official
system status : custom
iv had alook round and cant see anything that will fix it, in odin theres a clear efs button.
edit: just found this info on a usb jig that resets counter to 0
http://forum.xda-developers.com/showthread.php?t=1934771
how do I go about clearing the EFS since it is greyed out.
so there's no work other solution to this, except for getting the jig?

Edit the ini file for Odin and set PhoneEFSClear=1 that'll check the EFS Clear option (even though it remains grey). See if that helps.

same here
Has anyone found a solution to this yet?! I have the exact same issues, phone died, then when powered back on was stuck in a boot loop, returned to stock and got the unable to mount efs invalid argument text, now its still stuck in a boot loop with a flash count of 8 so cant be sent in for repair, any advice is greatly appreciated!
I have the exact same problem
i have the same problem . . and to make matter worse i don't even have any warranty . . :crying: . ..
is there no way to to get the phone to boot in to the OS regardless of any functionality ??
I couldn't find the topic where i learned this info, but it's something like this: if you flashed the modem (i think so) and you have an EFS backup like me, you just need to flash any other thing and restore the EFS backup. But, if you don't, you must stay with the modem.
okay, i just found it: http://forum.xda-developers.com/showthread.php?t=2332913
Good luck. (And press the thanks button if i've helped you :fingers-crossed: )

Seem to have been struck by the same issue and no efs backup prior to this.
Custom binary download: 0
Completely stock Note 2 just got screwed after flashing new 4.4.2 ROM for my country via Odin, the ROM booted fine, transferred contents to PC, factory reset the phone, set google account and reinstalled apps and transferred saved data back. Data, phone calls and everything else was working. The phone got to 10% battery lost network (this is normal lately lol) and shut off when battery died. Phone never rebooted and stuck at Samsung logo. Recovery reports "/efs I/O mount error" tried the guides by ketan and a couple others nothing seems to help
same applies to me. Perhaps some hardware fried is my guess.

Is there any solution for boot loop in gt-i9192?

Is there any solution for boot loop in gt-i9192?
My phone was rooted. I was using s5 rom proyect and my recovery was Philz Touch Recovery. I was happily using this rom for arround 8 months. Recently my phone was responding slow and my storage was almost full. One day while watching youtube videos my phone got hang! I just removed the battery and tried to restart. But there was a failure and no vibration. The phone is simply dead. I connected my charger and of :crying:course there was no indication. Later I went through several post to learn how to revive my phone from hard brick. I downloaded debrick.img file and made a bootable memory card. This time I was able to switch on my phone but it went through bootloop. The recovery mode takes too long to load and wiping cache and dalvik cache or even reset was not possible because of some error like E: failed to mount ......
Then I went into the download mode. and installed a firmware from sam mobile. Later I flashed CWM recovery through odin successfully.
But this bootloop still exists. Whenever I try to go into recovery mode it still takes a long time. And istead of loading CWM recovery it loads philz recovery mode that was previously installed
Please help I am tired

Dude,
I am also having a bootloop problem on my S4 Mini GT-I9192...
My TWRP recovery was working, I was using version 3.0.0.0 for serrano3gxx, but when I tried installing a custom rom, the right rom for gt-i9192!!!! for some stupid reason the twrp recovery keeps thinking that my phone is gt-i9190 !!!! it is so stupid!!!
for this stupid reason I couldn't install the ROM !!!
I decided to install the right recovery for my gt-i9192, so I downloaded openrecovery-twrp-2.8.7.0-serranodsxx-STABLE-signed
now, there was a warning to not install the zip using the recovery, but how could I install the recovery if I am unable to install anything with Odin!!!!
Nothing at all!!! I can't install anything with Odin, it just gets stuck!!!! So frustrating!!!!
And now afer I installed it said the installation completed successfully, but..... I can not even get the phone in recovery mode!!!!
What happened??? can anyone please help!!!
I am stuck in this stupid bootloop problem, and now on top of it I can't even go to recovery mode!!!! Nothing!!!
It is useless to do anything with Odin either, it recognises the phone, it says Added! but cannot install anything, it just gets stuck
WHAT CAN I DO?????
PLEASE HELP IF YOU CAN.
Check out
You can try this:
1. Download this file: openrecovery-twrp-3.0.0-0-serranodsxx-STABLE-signed.zip and copy the file in sd card
2. Then go to recovery mood.
3. Install the zip file from sd card.
4. hope you will be able to install the correct recovery mood.

I think you didn't understand... My phone is not going into recovery at all!!!
I had this problem once when I flashed an incompatible kernel, but I forgot how I got out of it. Best suggestion I have is take out the battery and put it back.
The "hard brick" you suffer the first time was likely a dead battery. The phone looks hard bricked when a battery is below critical energy, and not enough power is available to charge it with an USB. At that point, you had to wait for the energy in the battery to store up again, and then plug it into the USB to charge. Just a little power was necessary to get it charged again.
If you can still access download mode, flash the stock ROM baseband of your phone (you should know what this is). Your data will be wipe but at least you will be able to use the phone again.

Bro hard brick was not a low battery case. I kept it connected to the charger for almost a day. Can you please just say how to solve the problem. I am totally disappointed.

Bootloop - No Custom OS - No USB Debugging

Hello All,
I am using Samsung Note 3 Neo, unfortunately I have struck up with bootloop. I have read around and tried all the bootloop fixes but they all require the phone to have USB Debugging enabled prior for the fixes to work. Sadly for me, I didn't have the prior knowledge that that was available so I am stuck with a soft bricked phone with no work around.
Any help on issue is greatly appreciated.
Thanks in Advance
You can still access download mode (volume down+home+lock), right? Try flashing TWRP using odin ( i don't think you need to have usb debugging enabled) and then wipe everything and flash stock rom. Or if instaling TWRP does not work, flash directly stock rom using Odin. Hope that helps

I am not able to access download mode, I tried using volume down+home+lock button, Its not getting into Custom OS mode. Just black screen blinks and same samsung logo will come for thrice it will blink and then goes into bootloop
Hmm.. Can you access your stock recovery (home+lock+vol. up)? If you can, try doing factory reset and reboot. Not being able to enter download mode is really rare

Is your phone a Note 3 or a Note 3 Neo? These phones are two different variants.
Can you access download mode? (Phone off, press volume minus + home key + power at the same time until you see the phone starting to ask you if you want to procceed to access to download mode)
If yes, your model number is written at the top, download the latest firmware available for your phone model on samfirmware and flash it using odin, follow a tutorial if you are unsure cause you don't wana mess your phone up more that it already is.
If it cannot access download mode, this is gonna be a bit more complicated :/

Phone stuck in Bootloop! Can access Philz Recovery, but cant take backup!

I need some serious help here! I own a sim unlocked i317 (I bought it second hand and it was already unlocked-1 year back). It was working fine (except it used to get restarted itelf 4-5 times a day since past month) and then last night after completing charging it was working fine and I slept then. When I woke up, to my horror, the phone was stuck at "Samsung Galaxy Note II" screen. I tried after removing SIM and mSD, and then restarting it but to no avail!
So the phone is stuck in Bootloop, it had latest jellybean rom from AT&T that had been sim unlocked. Recovery menu shows Philz Touch 6 with some errors like:
​"Can't mount system/recovery"
​"Cant load system/command" etc.
I am here seeking help in retrieving my stuff on internal memory and, if possible, all app and phone data before I try a factory reset or install fresh rom!
Any kind of help would be highly appreciated! Thank You!
PS: I'm not a proper programmer as my field is DBMS, but since I have basic know how of programming, I would manage to try your suggestions!
ok this should be a fairly easy fix. I would stop using Philz recovery as a first step. You should be able to flash the newest version of TWRP without losing any internal data or storage. go here to get twrp and flash in ODIN. https://twrp.me/devices/samsunggalaxynote2att.html
Once you have this one your device boot into recovery and you can use the file manager to move and folders you want to save to an external Sd card. You may also be able to get a computer to recognize the device and copy your files that way.

Note SM-N930F boot loop Hydrarom

Hi All,
Sorry for my English, it's not my language.
I need your help because I think I have bricked my Note 7 after trying to install the last Hydra rom 1.3.5.
I explain you the situation:
I have installed custom TWRP => it was good
Then I have rooted with superU => it was good
Then I have tried to install hydra rom => the installation was OK
The phone reboot at the end of installation => phone stay on start screen "Hydra rom" and reboot (loop infinite)
I cannot power OFF the phone.
I cannot go to the recovery menu.
I can only go to the download mode.
So I have tried to re-install TWRP with ODIN but it was not working. Ondin detects my phone and when I click on start, I have the message "Fail" on ODIN and the phone reboot.
Do you have any ideas to help me?
Thanks.
Note 7 Problem - please help if you can, please
Hello
I am newbie here with no proper experience [ I flashed mobile with success once but it was years ago with NOKIA e90!]
I have Note 7 exynos UK VODAFONE and I did flashed it with older OEM firmware [ to bring it back to 100% battery], I downloaded from sammobile than recent one on my mobile [ limited 60% battery]
I unchecked re-partition
I used AP file there
all went fine with ODIN v3.11.1 all pass !
but once mobile started I have big message on my screen which does not disappear [ see attached photo]
unfortunately, the process
com.android.phone stopped
I can click/press OK on screen below that message, but it reappears again and again
I tried to flash it again but now ODIN says fail and something about PIT
I would appreciate some help or tell me what steps I should take [ apart of surrendering phone to place I bought it from!!!]
regards
M.
What I did to make this work:
1 install TWRP
2 whipe format data "yes" x3
3 advanced format everything except external storage
4 reboot to download mode
5 open Odin on pc flash BL/CP provided in original Post of HydraRom
6 install HydraRom via TWRP
7 follow direction installation process
8 wait 5 mins boom!
Never fails for me.
I did that. I have already did that several time before. But I think I have understood the problem. My BL file is corrupt (may be during the download from the server)!
So I think the boot loader not working correctly! I have tried to reload one but without success. Directly Odin write "FAIL"...
Able to access Download mode only after Hydra flash. Solution?
Did this issue ever get a solution? I am having the same issue. I can enter into download mode only after the attempted hydra flash. Now it's stuck on "Hydra N7" boot screen. I had N930F flashed and running with twrp. When I attempted hydra I believe that the full rom did not flash, only 40 MB or so. To make matters worse I can't find where I jotted down my baseband, etc. It was originally N930X (live demo model). Now I get fails in odin. What can I do to remedy my situation. I read that I should flash BPH6 base files, but here it says AGO or AG2 BL. Which is it? How do I wipe the cache and data since I can only access Odin mode? I believe my BL is corrupted. Please help. I was going to trade my Note 7 in but my imei is all zeros and the boot loop. I'm not sure that they will refund or exchange in this condition. Although, they should since I doubt Samsung wants the liability of having these devices out there. Any thoughts on the matter?
Any insight and guidance is greatly appreciated!
