If someone is having problems with NVRAM error in wifi section after installing custom rom and then reverting to original one then this thread is for you.
Disclaimer: I am not responsible for any damage done to your device.
With this out of the we can start. First of all you will need Sp flash tool an a copy of original firmware and working brain. First you will ned to extract your firmware zip that you can download HERE. After extracting firmware files you will need to edit Android_scatter.txt file under NVRAM section.

"lightbox_next": "Next",

}
In file_name you have to change NONE to nvram.bin and is_download to true. After that it should be looking something like that.
Now save and exit notepad text editor. After that you need to copy nvram.bin file that you can download here: NVRAM.bin and move it to extracted firmware folder. If you have any problems with error checksum mismatch you have to delate Checksum.ini in your firmware folder. If everything was done correctly you should be able to see nvram option in download tab.
Deselect everything expect for nvram and then click download button. After completion reboot to system. Now this error should be no more. This method should work for all mtk devices but you will need to extract nvram.bin file from normally working device you can follow this Youtube Tutorial.

Hi
I would be very happy if someone could tell me how to re-sign the ROM after I add and delete stuff to /system/app? what do I need?
thanks
edit: I read this but the link is dead, can't download.

Don't bother. If your recovery is set to check signatures, your rom will fail unless it is signed by the device manufacturer.
It would sort of defeat the whole purpose of signatures if you could just change something and re-sign it with the original signature.
Dont ask me to ever explain the math behind the crypto, but I can link a wikipedia page

There are a few ways to resign your changes to a custom ROM but you may not need to resign if your custom recovery doesn't check or if you use something like 7zip to open the zip but not actually extract it while making your changes. If you do need/want to resign, there are a few possibilities. A couple android apps can sign files on your phone itself: Signapktic or ZipSigner. There are also tools for your computer floating around xda to sign zip and apk files. I have a droplet called Android-sign(mac-only) to use every now and then. Also, there's always the testsign.jar method from the command line.
Code:
java -classpath /PATH/TO/testsign.jar testsign update.zip update-signed.zip
Hello guys,
I actually own a windows ce 6 device called "Zune HD". There's an application made for it that allows to run cab files from windows mobile, but you have first to get some libraries.
So here's my problem: I tried to install Opera mini 10.3, but a DLL named "Cellcore.dll" is missing in order to run it.
So you guys have two options:
Give me a download link to cellcore.dll
Create me a dummy DLL with empty functions to pretend to be cellcore.dll
Thank you very much!
try these
(one of them is from my rom kitchen but dont know how to convert it into full .dll)
the other is a blank/dummy .dll
Rn
found this also so might be worth looking into these registries:
[HKEY_LOCAL_MACHINE\COMM\DTPT]
"dtpt_controller_dll"="cellcore.dll"
"use_dtpt_for_process"="UseDTPTForProcess"
Thanks for the fast answer!
So I'll first try your DLLs and I'll give you the result ASAP
Update: I put your dummy DLL in the installation directory of my game and it still does'nt work... :S Bizarre...
duno then dude
good luck
had a thought..
download HTCRIE
this displays the contents of a rom, eg:
1) a whole rom is a .NBH file, a rom has parts, which are .NB files

go into *OS and save your .dll file

Click to expand...
Click to collapse
Open the md5 using 7zip and extract the files to a folder.

Hi everyone, I'm having a couple of problems flashing the required Rom's Bootloader & Modem (XXU1COI3 & COI3) for my phone (N910G - 32Gb).
So the problem look like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I had also try to extract the pit file from the phone using terminal emulator on Android. Used that pit file along with the flashing of Bootloader & Model. This is what it shows:
I have previous problem similar to this before. But it seems to work when I used the PDA tab while flashing both the Bootloader and Modem as a single tar.md5 (or tar file can't remember exactly).
I would be very appreciated if someone could merge the 2 file together (so I can give a try) or come to a solution for those problems.
Cheers!
untick autoreboot
Second this.... also unticking AR did not help.
Don't use Re-partition !
And don't forget to power off the phone (minimum 15 seconds) and start in download mode directly before flashing BL and CP
Hi guys,
I get this SM-A310F(310Fxxu4crg2, this string i grabbed from my recovery) phone for testing purposes and now I want to go back to stock rom, but it's my first expierience with Odin/Heimdall and I really don't know what I done, my bootloader seems to be working, i mean it boots successfuly into download mode, there I tried to flash with Odin BL, AP, CP, CSC with these files https://sfirmware.com/downloads-file/26048/SM-A310F_1_20180814174814_3yq6smui2j_fac
The ZIP provides 4 files:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
these files I selected in Odin:
but like you see in this picture from Odin it does fail, and I really don't know anymore how to get back to stock.
I also try it with Heimdall under Linux and extract the tar files from my first picture and selected them manually, with hidden partition gets the hidden.img and so on, but there I get also a error something like a protocol error. I also have a pit file I created with Heimdall, before I mumbled around, if it's needed.
Windows 10 Pro, Odin 3.14, Samsung driver installed
Archlinux with latest kernel, latest libmtp & Heimdall
I hope someone can help me
