SM-G900H Clone Null IMEI, ROM, CWM Recovery - Miscellaneous Android Development

Hi.
I have a BIG problem in my hands, ok but i smile anyway .
O spent a lot of days looking for a solution to fix my Null IMEI but no chance.
The phone is a CLONE Samsung S5 SM-G900H with real MT6572 (MT6589 is fake), we can see on image the MTK Droid tools diagnost.

Well, i flash one Rom before a backup de NVRAM and i lost the "/efs" directory so, i don't have the ".nv_data.bak e .nv_data.bak.md5" files.
Anyone can say me where can i find the solution? I tried almost everything, the IMEI can't be written always.
I guess i need the original Ubifis ROM for this phone, to restore "/efs" directory or the NVRAM/IMEI backup for this one.
I tried flash some Roms but no one works because of blocks, partitions or something.
Some correct ROM to flash with SP Flash, already rooted with CWM Recovery and /efs is the perfection .
Thank you in advance!

[Q] My Galaxy Nexus Sprint Mount partition

A years ago I messed my galaxy nexus sprint,
After trying this and that, I dumbly restore EFS partition with samsung galaxy S EFS (i'm forget, but it is obviously another phone EFS, not galaxy nexus).After that, my phone bricked so hard. Luckily I can restore my phone with USB jig (to enter the OS in my phone) and OMAP method: http://forum.xda-developers.com/galaxy-nexus/help/galaxy-nexus-bricked-omap-flash-kinda-t2148093
Now, my phone works like wonder, everything is good except I can't make a call nor SMS, the signal logo is empty (no bar), but it work perfectly with WI-FI, and everything goes unknown (like baseband, network, IMEI, MEID, etc)
Now, I found this thread about the phone folder structure from here: http://forum.xda-developers.com/showthread.php?t=888193
I tried the code and here's the result:
{
"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_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
All i want to do now is to flashing my friend's Galaxy nexus EFS backup, but i got confused with the folder structure. Does anyone knows about this folder structure or even experience this problem before?

[MT6592] Full dump rom with a big FAT adress for SP flashtool.

Hi,
I have a Jiayu S2 16GB with a MT6592.
I'm looking for a way to make a full backup of my ROM (system + userdata).
Unfortunately, I found only both solutions.
First with MTK droid tools ( it requires to have the phone turned on then I think it isn't able to make a FULL backup) and it requires a root device.
Second, use SP flash tool and the "Readback" Tab but I need to get the end adress and I don't have it.
Some tuto said to get the inital adress of the "FAT" part but the size of the "full" backup is only 300MB.. ( The system partition on the setting shows more than 3GB)
EDIT : I found why ...

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Then I can write the right adress... In SP flashtool, we have to remove two "0" but there is only one...
Help me plz ...
I really want to make a kind of "iso" of my whole phone. (system partition and userdata with internal fake "SD" partition)
Thank you very much for helping.

Hi, everyone. I have just install the CM11 for my Samsung Galaxy Ace 2 (i8160-TGY) : http://forum.xda-developers.com/showthread.php?t=2555021

I have tried a few things before I came here:
1. Use EPS Professional to make backup of EFS and restore.
2. Tried to access the service mode but it failed.
3. Change the access permission of the EFS folder.
However, if I flash my stock rom (Hong Kong, 2.3.6 Gingerbread) back, everything is normal.
I would like to ask if there is any way to deal with this, thanks!!!
Is there any people?
Hi there,
The best place to receive an relevant answer is in the dedicated thread for that ROM from here: [Q&A] [ROM][4.4.4][TeamCanjica] CyanogenMod 11.0
For any other question please use this thread: Q And A for Ace II
Good luck

How to install LineageOS/ResurrectionRemix Roms for P900 to P901/P902

As i told before you can install P900 LineageOS or ResurrectionRemix Roms on P901 or P902 devices. Difference between P900 devices and p901/p902 is only P901 and p902 has modem (mobile data) on it. Other specs are similar.
So here is how to install P900 roms.
1. First extract downloaded rom.
{
"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"
}
2. Go to \META-INF\com\google\android and Edit updater-script
3. Delete the line which checks product name.
it is usualy on first line. Try to fine something like "getprop("ro.build.product") == "v1awifi" || abort("E3004: This package is for device: v1awifi; this device is "... and delete this whole line
Save and close.
4 Repack all extracted files as .zip format
Finally copy your device the zip file and flash it.
If it gives error while flashing try to wipe system partition and try again. Dont forget to flash Gaps after rom. Good Luck
Do everything with your own risk.
thanks a lot
@[email protected] does anyone test it? I'm a little bit scare cause I already brick a phone while I'm trying to flash new rom @[email protected]

[HELP] Realme 8i RMX3151. Touch Panel issue. Missing Driver?

Hello Guys.
Since few days I'm fighting with my phone. One day I decided to Root my Realme 8i (RMX3151) and install Any different ROM. I did it and At First Look it was done well. But I realized that My IMS, Carrier don't Work. IMEI was corrupt. I repaired My IMEI etc. System
I was receiving a notification from the system "SIM 1 not provisioned":
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

It was hard fight.
When I Wiped my Data/Dalvik/Cache and after boot I can see that my phone is Connected with SIM Provider.
SO one problem is gone but new appear.
TOUCH is not working. Cant click on anything. OTG on that stage is not working too. Only in TWRP.
