[HELP][SOLVED!] Cannot restore IMEI after downgrading

Hi guys, as I explained in the related thread, after downgrading from ICS to GB my O3D p920 thanks to berni's guide, I'm now having troubles fixing my IMEI.
I followed this guide http://forum.xda-developers.com/showthread.php?t=1734330 without success.
After a short conversation with Pesach85 I noticed that, when connecting the phone to my PC in debug mode it normally detects and installs all the new hardware. But, after dialing 3845#*920# and selecting "CP Download image" from "Port settings", it seems to DISCONNECT ALL THE PREVIOUSLY DETECTED HARDWARE, and installs a new device (Intel(R) flash loader utility).
If someone tells me how to let all the hardware stay connected to my PC, I would be able to fix my IMEI with tutty.
if there's another method to fix the IMEI please write it here.
PLEASE HEEEELP!!

I've been in the same position for a while. Make sure to try the LG Support Tool recovery in S/W mode. (Remove battery, unplug USB, press vol UP, plugin USB - Power + Vol UP. It should show S/W mode. Depending on which loader it should show some korean text).
If you enter your IMEI number to repair the phone it should fix it all. Tho if you came from ICS you might need to do a factory reset after that when the phone boots (it will nag about no space available).

^ +1 This works. It will unroot your phone, but it will restore your IMEI.

Restoring IMEI
1.Connect phone by USB
2.Activate USB debug mode
3.Enter 3845#*920# in dialer if that doesn’t work try 3845#*925# or 3845#*720# if device is SU760
4.Select Port Settings -> Select CP Image Download
5.A new device should appear at let it install
6.Open Tutty (or hyperterminal) and select serial protocol. Click on open
7.Type AT if response is not OK, change port number (it is possible that when typing you don’t see any letters)
8.Type at%imei, it should display a dummy IMEI
9.Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x where x,x,x... is your orginal IMEI number (found under the battery of your phone). It should response IMEI WRITE OK
10.Reboot phone

But little changing in the above,
step 3 depend on your phone model or rom in it like for SU760 code it 3845#*760# and for P920 it is 3845#*920#
in step 4 I selected CP USB instead of CP Image Download or CP Reset
Final I was unable to get it to work in Windows 7 so I tried on Windows XP in my office and method magically worked and my imei is restored. I can make call and so on now

hey
I not have the SU760 for the long time and was not visiting the forum much, sorry for not replying earlier but it may help other if your problem is already solved
Hopefully your problem is already solved if not, after step 5 check the device manager what your phone is assigned com port com4, com5 or whatever com"xyz" xyz is a some number then in the hyperterminal in All Programs -> Accessories -> Commincation -> Hyper Terminal and in new connection select the com port your phone is assigned whatever that xyz was and start the connection and proceed.

Using LG G4 H810 (MSM8994) on QPST 2.7.425 for IMEI Repair/Replacement

Hello fellow android users, I am trying to use QPST to repair a bad IMEI on a LG G4 H810. Stock rom, no root.
After alot of trial and error i've (almost) done it. QPST reads the device as a phone (MSM8994). I am able to backup the QCN file without any errors. Then I am able to use Ultra Edit to change the IMEI in the correct flipped format. Afterwards when i try to use QPST to restore the QCN file it gets to 23% then says its unable to write to device.
I am reaching out on this forum for help. Any and all would be much appreciated.
UPDATE: I know it has to be an issue with the device not allowing QPST to write. I read somewhere you have to switch the phone into DIAG mode to allow QPST to write. There isn't a DIAG mode on the G4. Not even in the hidden menu from what i can see. Thank you all for any help!

Try download mode?

Upload the qcin file

have you solved? can you explain the exact procedure to follow? i have the same issue

enabling diag mode

Is it fixable? Bricked S6 won't boot or accept ROM flashes.

Previously, I've talked about how I bricked my G920T by using an apk to try to root my phone.
Then I tried to do a factory reset with the stock recovery but it wouldn't even go into the stock recovery. So I flashed TWRP and wiped the whole phone including the system partition.
Then I tried to flash a stock 6.0.1 firmware to the phone but doing so did not improve the situation as my phone still won't boot. Even worse, when I power my phone, all I see is the blue LED indicator, no Samsung logo, nothing.
Then I tried to flash a custom ROM like XtreStoLite but that didn't fix anything either.
When I use TWRP or the stock recovery, the error "failed to mount /efs (invalid argument)" comes up on the log. I tried using the ADB method to fix it but my phone would not get recognized by ADB probably because USB debugging isn't on by default.
I cannot shut down the phone without having it charged to a power source then holding down PWR+DOWN VOLUME+HOME until the screen shuts off.
When I enter download mode, I don't see the warning screen, I enter the download mode directly.

It will warm you when you enter download. Or use TWRP and reboot into Download.Once in download flash the ROM using Odin. Get the latest one from SamFirm.
P.S. Next time root using CF Auto Root

It doesn't warn me when I enter download mode, that's one of the problems.
I tried flashing the official ROM using ODIN, it still won't boot because of the efs error.

1) Download the latest SmartSwitch
2) Click on more -> Emergency software recovery and initialization
3) Go into Device initialization, enter your model name, search for it and proceed as advised by the assistant
That should fix everything, otherwise:
1) Download the latest official firmware for your model, the 4-File (or 3-File) Version
2) Use latest ODIN, check repartition in options
3) Select all the files and flash it

If EFS or DRK is corrupted, flashing roms, custom or not won`t help, it can be fixed via repair box maybe (Octoplus/Z3X)
Try to flash CF auto root for your model, if it still won`t boot, then find someone with a box to try to help you remotely or not.
But Smart Switch emergency initialization with phone sn would be the first thing I would try.

Which mode should I be in when using SmartSwitch? No devices are shown when I have it plugged in during the bootup, and is so too in download mode but shows a not supported message.

Well if you know someone who have a box, it doesn`t have to be remotely.
If not, it is possible to fix it remotely, with help of usb hub (FlexiHub or similar), tunneling (TeamViewer or similar) and box software (you connect phone to your computer, the other guy connects box to his computer, both of you are connected through a gateway to a wonderfull thing called internet, and everybody is happy ) .
Same as on site, just with few more things in between the phone, and the box.

The S/N sticker on the back of the phone is long gone, is there any other way I can find it besides from going into settings because I can't do that?
EDIT: I am able to borrow a friend's serial and got the firmware installed.
The Samsung boot logo is back now, however, the device still won't boot. The efs error is still there but the download mode warning sign came back.
EDIT #2: Okay, I flashed TWRP now and ADB is working once again. Can I utilize this to fix the efs error?

"Custom Binary blocked by FRP lock" & Odin/PC won't recognize the device

"Custom Binary blocked by FRP lock" & Odin/PC won't recognize the device
Okay so,
My phone has been rooted for a year, I disabled OEM Unlock by accident, my antivirus was always telling me its unsecure with this feature on and to 'click here' to disable it.. I forgot how important this was to have enabled while rooted and ended disabled it and that night rebooting my device.
I get this error when trying to boot my device:
"Custom Binary blocked by FRP lock"
I have the original stock firmware, and Odin and want to reset the phone but when I plug this device in ( while in download mode ) > the windows PC doesn't recognize it (no new device sound or any change in devicemanager) and therefore odin isn't recognizing anything either - - I can grab my other 2nd-device and boot it into download mode, plug it into the same setup and boom > recognized and 'Ready!' Status in odin almost immediately so I don't think it's my PC or the cables -- I don't think 1st-device has usb debugging enabled either and I'm not sure how to proceed ...
any help is much appreciated ...

Try to use Smart Switch (from Samsung website), which also has the latest drivers, to recover your phone. (Google "how to recover with smart switch")

Alright,
Forgot to mention I tried Samsung Kies but cannot find the serial number on the device, I'll give Smart Switch a try this evening on my other PC and report back... hopefully that PC recognizes it, my tablet connects to this laptop but not the phone.. could USB debugging being disable cause this?
How close to bricked is this?
I'm such a fool!
Thanks for the feedback so far..

Hi boot tar flash odin frp lock of after stock rom flash

I went through this a few weeks back. I found my serial number (was a sticker originally on back of phone) and used smart switch to recover firmware. Then enabled developer options, oem unlock, flash TWRP thru ODIN etc etc.

So if I find the serial number, I save it .. good to know, thanks!

Hey man, im having the exact same issue with my S7 edge.
So I got my IMEI number, and with my number I went to imei. info / and I got my serial number through a warranty check through the site, you have to register to do it.
I used Smart Switch and I get an error when trying to use the emergency recovery "Model number cannot be initialized"
I'm also getting the error on my PC when trying to connect my device to odin saying that "USB device cannot recognize" and with that I cannot flash the stock firmware on the device.
So if you have gotten any solution to the FRP lock please let me know.

Serial number is engraved on back cover next to the imei number -,- @samuraichick0n about "Model number cannot be initialized" try to write it in diffrent forms eg. G935f or SM-G935f uppercase or lowercase.

PC doesnt want to recognize my device, so Odin doesn't pick it up.

Try it with other usb cable. What is given together with the charger is incongruent, it happened to me, the same problem. (galaxy s6, s7)
And you need the newest odin. Excuse me my crappy English.

Hello, after exhausting all options I had to take the device to Samsung themselves - eventually they had to replace the motherboard on the phone to fix it.
So check if your phone is under warranty and take it in.

I fixed this when I first rooted by flashing the stock bootloader, firmware etc everything through odin

Thanks

OPPO A3s - user password removal

I have OPPO A3s need to remove user password somehow, even in recovery mode phone asking for locks creen password to factory reset or flash, phone goes in Emergency Download Mode (EDL) if open recovery, connect USB cable to PC and click on Build number 3 times.
So far i can think of two solutions:
1. Mount Filesystem (this guide) with Qualcomm Flash Image Loader (QFIL), phone is detected in QFIL as HS-USB QDLoader 9008 once in EDL mode, but then what, i dont have MBN file required to mount filesystem can someone help?
2. Flash stock firmware, i can download two, from official website in CPH1853_11_A.31.qzip which i can extract, but then what?
Other firmware is unofficial in Oppo_A3S_CPH1853_11_A.21.ofp format this cannot be flashed by any tool i know of, there is info online that OFP file can be converted to proper format for QFIL (with scatter file and xml) by software+usb dongle (Miracle Box, UFI Box), but they are not free.
P.S. I am noob please help.

Hello

hello , does anyone have oppo a3s download certificate, that the only thing standing between me and unlocking it
