Hello , this method works with sm n910f also ?

The device remains unlocked ?

I have unlocked my device by writing a cert , original efs was deleted form service menu , before writing the cert file . I have flashed multiple stock rooms , including repair firmware .

But my fingerprint sensor don't work anymore, so I'm thinking by your method i will repair it.

I want to mention that , i have no errors when i flash rooms , or factory reset with custom or stock recovery, the only error is when i flash the repair firmware it's fail writing "hidden.img" from csc file , so i must to flash it manually .

My second problem is with the signal , 2g networks don't work , and 3g-4g signals are week .

In a N920T Note 5 dont appear mmcblk0p3 only sda*, is sda3 the same of mmcblk0p3???

The comands can work replacing mmcblk0p3 to sda3 ???

For format efs:

1. mke2fs /dev/block/sda3

2. mount -w -t ext4 /dev/block/sda3

3. reboot

???

Thanks

Can confirm that DRK fix does not work on SM-N910F. Maybe it has something todo that IMEI data (and therefore DRK, too?) are not stored in EFS volume...?

Does anyone have any idea of this works on a 910w8 Canadian variant? My EFS folder has many files none that are listed on this thread.

i have this issue on the 910V ..... youtube videos stutter and when typing some words they keyboard, well all keyboards stutter too... this began to happen when my phone started showing me this message; I could not find 4 file firmware N910V

Hey sir, did you find any solution for it?

[Galaxy Note 4 General] jaazzmangeo:
I solved this problem by replacing the fingerprint sensor. Drk here will not inject
[Galaxy Note 4 General] xdathekilljoy:
I'm not sure where to go. I have the N910c and I did have an EFS backup...which I though I had backed up, but found out too late I didn't. And of course that had to be my random moment of being like...Yeah I should wipe the entire device...Internal and all :eek: :crying: Then came the DRK issue.

On top of that I can't even be fore exact sure which is the true original CSC and have no serial number access due to this being a replacement motherboad. The original all works except for the pen.

I thought since maybe EFS may have been messed up already this wouldnt work, but tried anyway. All went smooth except for the problem remaining still.

I'm having the exact same issues on my N910P from Sprint.

Has anyone tried this fix on Sprint's Note.4 yet?

OP, is there any reason why I shouldn't try it? I've ODIN'd like 4-5 stock ROM's and it still happens. Is there something I can read in buildprop or something that'll verify something is amiss before going through your steps?
[Galaxy Note 4 General] m5james:
Worked on Sprint Note 4 N910P as well!!

My own personal update from a Sprint N910P user...worked awesome!! No more typing lags, delays between button inputs and phone reactions, etc.

I created a folder called "efs.bak", moved everything from the stock efs folder into the backup and powered down the phone. I rebooted into recovery, wiped cache, mounted system (might be unnecessary) and wiped cache again. Rebooted the phone, took a little longer than usual but it came back without issue. After a few minutes I got a popup on my screen saying "Android has successfully updated", a new EFS folder has been created (oddly my .bak is gone) and I can see that most files/folders are created on todays date...and here I am typing without any lags!! Thanks for this!

I've yet to reboot and see if this fixed my DM Verify and/or DRK warnings, but being lagless for daily usage is worth the 2 min this took vs HOURS and multiple times I've flashed different ROM's, kernels, re-setup my phone, etc etc. trying to fix this!!
[Galaxy Note 4 General] cirokv:
m5james, would it be a problem for you to explain part of the part of the procedure that you did? Do I need to have stock rom first? thank you

if the serial no didn't show use the following :

chown -R root:root /efs/FactoryApp/serial_no

and the correct permission for the CSC is :

chmod 664 /efs/imei/mps_code.dat

When i press 112 and call it is just showing emergancy call and keep dialing. Please tell me what i have to check and what i have to do to solve this issue..
[Galaxy Note 4 General] DaRdamnDoG:
Thanks for your files and guide, I managed to reset my Galaxy J2, it was a long night I must admit. I spent about 6 hours trying to figure out everything (first attempt I flashed the files without applying my original CSC & serial number, so it went XXX and 0000000000 on the status, which forced me to re-do it. While all these happened, my PC's registry and environment variables went haywire... Nonetheless, what's important is things get done in the end.

Cheers mate.

I flashed my n910h to air rom and got unknown baseband and imei , then i go back to stockrom, but my baseband keep showing unknown

I've tried step by step using z3x software cracked then my baseband is back but my imei had changed and i cant use network

If i follow this step , can i get my original imei back sir ? Please i need a help
[Galaxy Note 4 General] magix01:
Its been a long time i have been on this thread since i dont have note 4 anymore, there is NO way to get original IMEI back if you dont have backup. Only thing you can do is flash another imei with Z3X.

What if I have both IMEI and SN but Emergency Calls Only ?

I have N910C

I may still have Original Imei and sn backup but with that one it has emergency calls only

I flashed another cert with different IMEI got network but then IMEI is different now I have heard people to change IMEI using hex editor method

I was trying another fix so got drk error too

So you have any suggestions ?

Got efs back for both certs

One IMEI intact no network

Two IMEI different but with network

The Z3x version I have doesn't support IMEI rewrite option since I don't own a box can't have other versions

mke2fs /dev/block/mmcblk0p3 not found in twrp even after mounting efs and system

[MENTION=5639429]magix01[/MENTION]

Some how I managed to get to step 3 where we get imei back with network

the problem is my EFS was fine with IMEI and SN just Emergency Calls Only

after formatting efs part with different IMEI network comes back for few seconds on every boot and then its gone again

anyways I went and restored IMEI using ADB commands in step 3 but after restoring original IMEI back to Emergency Calls only I am guessing my IMEI back up is missing smth for the radio is there a way to fix that?

as in my previous post flashing a different cert does fix the problem but with different IMEI

or is there a way to apply original IMEI on different cert box is no help smth I could do?

Fix drk on galaxy note 5

Sir i shall be thankful if you tell me how i can fix drk on my galaxy note 5 sm-N920C .

This happened when i was using a custom rom but before installing the custom rom i made a backup of my efs,system,boot and all other options which were available in twrp...

After some time i wanted to revert back to stock so i simply installed the backup through twrp. But after installing that backup, device got stuck on samsung logo and finally i decided to flash stock rom thorugh odin but all in vain, after installing the stock rom the phone started showing drk error in stock recovery mode and now it won't goes beyond the logo. The recovery mode opens after the logo and shows drk error.

Any help will be highly appreciated

Hi

I've recently had a root, unroot, 2 custom roms and back to stock.on a 910F.

I got the DRK error at the end of the Odin flash to stock, but it's booted fine and seems to be OK, although I've not really used it and have left it to settle down.

If it's working, do I need to worry about the DRK error?
[Galaxy S 5 Q&A, Help & Troubleshooting] PsyCLown89:
Hi All,

So I have an issue with my S5's GPS... I now suspect it is due to the antenna however would like some feedback and assistance.

I downloaded the "GPS Status" app to try and trobuleshoot a bit. When I open the app with my location on and set to any of the 3 accuracies (GPS only, Power Saving, High Accuracy) and very quickly it manages to find satellites, at the moment 26 of them.

However it is unable to connect / fix to any of them, so it is displaying 0/26.

So since it is finding the satellites but unable to fix/ connect to them I am hoping that my GPS chip is still fine but the antenna is the issue - what do you think?

If you think it is the antenna, how can I go about fixing it? Is there somewhere I can open up the phone and resit a ribbon or connector or anything of that sort? If so please can you assist me with how to go about doing this.

Thanks!

Psy

Nice one, yea it didn't sound like hardware, seeing the sats showed the antenna/GPS chip were fine

Long story short, woke up with my N6 stuck at the bootloader screen and cannot do anything at it. I can only see my serial number and if I try anything else, it reloads bootloader. I am trying to flash back to a stock 6.0.1 image, however I keep getting this error while trying to do so.

I have tried Nexus Root Toolkit, tried flashing all and tried flashing each image one by one but I still get this "(bootloader) Failed to flash partition FAILED (remote failure)" on all attempts. Phone does show up if I try fastboot devices, and I have tried this on two different computers. Device is also unlocked as well, and I even tried flashing older versions of Lolipop but they all give me the same error. Drivers work fine, and I have everything up to date in terms of bootloader and Andriod SDK. I am starting to think that there is physical damage inside the phone, however I do not know how or why this occurred randomly. Any help would be awesome, as I am very new to flashing images onto my phone and frankly I am 99% sure that my warranty is out, and I really don't want to pay $175 cost :(.

Any image I even try to flash I get the error with, no matter what order or which one I pick. I redownloaded the image again and still nothing, so I don't think it's a corrupt download. What is the unlock command? Sorry for being a noob, never heard of it since all my knowledge is from reading tons of flashing guides on the internet lol.

Alright, I downloaded the OTA file and got the process to about 47% when suddenly I keep running into the error of "E:Can't open /cache/recovery/log" then followed by more things it can't open. I tried the OTA twice and it gets stuck on that same exact spot. I tried the wipe data/factory reset option from the recovery mode and I get a similar error of "Can't mount", "Can't open", "failed to mount" the recovery log. It seems like there is a problem with the recovery log files (or the folder) on my phone, but I have no idea what that means. I will mess around with some more and try Googling the source of error, but thank you for the help.

Oh yes, my device has already been unlocked from the start so that wasn't a problem. I still get the same error when I try to flash anything, including TWRP which means I have to install the OTA. The problem is a get a separate error when I try to install the OTA, which the only solution being to flash my device (or at least that is what most people have been saying when I googled the can't open cache recovery error) so this is a giant goose chase which leads me back to the start :/.

I don't know the commands to erase everything from the bootloader but I would try this:

Flash latest twrp and boot into recovery.

Assuming you don't care about anything that's on the phone, go to advance wipe and wipe EVERYTHING lol... reboot into bootloader and try to flash everything from scratch. If this doesn't work, I'll guess your phone have problems.
[Nexus 6 Q&A, Help & Troubleshooting] xKizume:
I get the same failure error while trying to format and erase, so I am guessing something is really wrong with my phone or the bootloader is messed up beyond repair. I guess it could be the cable I am using as well, that is one thing I did not take into factor so I will try with another cable if I find a spare. Flashing might be beyond my solution at this rate though... Thanks anyways for the help.

Yes try another cable, if it stops at 47%, the Bootloader should be replaced. May try everything without simcard, don't ask me why, i read something similiar in a Moto forum
