Forget all that I said ….
After a couple of configurations, the system took the 2 SIM, they must leave the SIM 1 and ISP.
Works well …. will report any errors
Thank you !!!
So… The slowness problem is fixed?
If I understood well, just one sim (sim2) working properly? Did you tried to restore the modem.img from your X2-CU version?
It must fix sim problems
Hi,
I've the same issue, I lost my SIM-1 IMEI, But SIM-2 Working fine.I don't know what to do, Can you help me on this Please.?
Hola Sergio, como te puedo contactar, no puedo con mi vibe x2, y quiero actualizarlo..
it don't want download in my phone!!
The best rom that X2 CU phones ever had.
I can't understand why lenovo created CU version.
Thanks alot Eryen for uploading this rom.
Great work eryen.
Thank you for being such a great helper.
I'd like to make sure that the dual-sim functionality will be kept on my Vibe X2-CU after installing this ROM. As the pictures attached to your post show only one mobile network instead of two.
Also, how can i backup a real nvram file and how to restore after to keep my imei information?
Thank you for your help.
I generally use my device with one sim. But tested with second one, both of them worked.
Forgot mention about nvram. Install twrp recovery before install this rom. Backup nvram in twrp. copy backup file to your computer. Install this rom.
Insstall twrp again, restore nvram again. Wipe data.
Thats all.
Thank you eryen for your prompt reply.
I need to know how can i backup a real nvram file and how to restore it after installing the ROM in order to keep my imei information?
Thanks in advance.
Sorry for repeating the question. Didn't see your answer before posting it for the second time.
Thanks again.
I've uploaded a new image, that show two sims activated and voice,sms,data dedicated to sim 2. I hope this will ne enough.
Best regards
Thank you for your dedication.
But as I'm new to this, where can I find twrp?
it seems there's a special version of it for each phone model.
Hello everyone
First of all, I want to thank Master Eyren.
Install the version Vibe X2 AP today: 21/6 at 08:00 am and until 21:06 the room runs stably finally dual sim works seamlessly, GPS, Bluetooth, updates, all in perfect condition; The only problem I have is that the wifi signal does not connect well (I have the modem to 2 meters away), I think it is a lesser evil, comparing and worked the phone.
Dear Eyren, you did a great job !!!!
Anyone know how I can improve the WiFi signal ???
Thank
Esta en perfecto español!!!!
Some time ago, I flashed my current custom ROM into my x2-CU phone. I was very careful to select "Firmware Upgrade" or "Download only" not "Format All + Download" to avoid losing my IMEI and MAC.
Will this be enough when flashing this eryen's AP ROM to x2-CU? Or I'll still need to use twrp to backup nvram and restore it after installing the ROM?
Anyone who has tried this successfully can tell us.
By the way, I've failed to boot in recovery, although I've installed and run twrp successfully. It said that i had a secured boot.img.
Any suggestions?
To convert CU device to AP/EU device you need to backup nvram partition, copy to computer.
Flash EU/AP firmware with Format All option. (This will wipe all your internal storage too, so backup them too)
Flash TWRP recovery again.
Boot into TWRP recovery directly, Your pc will recognize device as MTP storage as well. Copy your NVRAM backup to device.
Restore nvram again. (You can also flash supersu here to root)
Boot as normally.
Best regards
I’m test
This firmware for x2-cu
First I’m not los imei and wifi no error
But sim no detect network
So I’m reinstall this firmware with format+down load
Yes I know I will lose imei
I want that
When finish install firmware
And restor NVRAM
I Think sim can detect network
But noooooo work
Any body have solve this problem tell me ptell
Note
When lose NVRAM and restor within recovery
May be lose again when format device
If you want dont lose NVRAM AGAIN
FIRST ( this method for any device mtk )
Take bake up from nvram from any recovery before do any thing
Second if any firmware you like it restore NVRAM IN anew firmware
Three use tools Maui 3g for support your devices
To Prove NVRAM
Usally use thus methold
Lenovo p780
Lenovo S850
Lenovi S650
Lenovo A369i
Lenovo Vibe xs960
And more not remember now
Trust me this perfect and best to prove any NVRAM
MEAN Don’t worry if you will lose imei
You can restored and reflah any firmware
This is not a custom rom, official rom. So if you have some problems with network, that depens on your device/sim card, or even missplaced simcard in tray.
I have attached images, that shows both of my sim cards active in same time.
Sorry I forgot something
About NVRAM ( BACK UP OR RESTOR )
YOU Can make this
Mtk droid tools or any recovery
But mtk driod tools no support x2-cu
So I’m use recovery
Thankssssss
Thanks ah_es_2000 for your reply.
What recovery app did you use to backup and restore nvram for x2-cu phone?
