[Android Q&A, Help & Troubleshooting] ibaitxozk:
Restoring nvram

A simple doubt:

I've read that to be able to use the cu kk-ROM bands in the ap lollipop-ROM i had to copy and restore the nvram, and others said to copy a couple of files from the firmware folder. Which one is correct?

And, if I had to backup the nvram, could I do it with a root browser and copying the files to the computer or it has to be done from the recovery?

If it is, how can you backup your nvram from the recovery?

Thanxx
[Android Q&A, Help & Troubleshooting] ericp2:
Hi, you are confusing 2 things. nvram must be backed-up as a partition as far as i understand. for that, you need to flash first TWRP recovery for CU, do the nvram partition backup, and save to PC.

after flashing the Lollipop S223 WITH FORMATTING, you will need to flash TRWP for AP lollipop (they are different, because phone partition layout is different), and then after copying back the nvram partition backup, restore it in TWRP AP.

the couple of modem files are to account for difference of band support between CU and AP models. Eyren has provided zip update earlier in this post to install it from TWRP. I have a CU converted to AP, and it's absolutely necessary to install the modem files or you will not get one or both sims functionning correctly.

Hope this helps.

Hello

Bro. Can u help me downgrade my phone from lollipop to KitKat ? Lollipop is too slow for me! Pls help.. M rooted on x2 AP n twrp is installed... How can I install d stock rom without losing imei etc stuff?! Pl help
[Android Q&A, Help & Troubleshooting] ericp2:
Hi, i have not done this, because i am happy with lollipop.... so these are unverified steps, do this at your own risks of course!

i assume you want to go back to CU KK from AP Lollipop (otherwise, you only need to flash AP KK, that's all! get it also from needrom!).

You already have an nvram backup, so you will need to

1. flash X2-CU 1520 (you can find it on needrom), using format all option (since file system layout is different!) with flashtool.

2. flash TWRP-CU (download only, select only recovery), also can be found on needrom, but you probably have it already.

3. start you phone, and copy the nvram backup to the phone (which is now completely empty, no images, music, etc...)

4. reboot in recovery, and restore nvram from backup

5. reboot phone.

no need to change modem files, since CU-1520 has the right ones for the CU model.

Modem files

I know that this has been already told in this forum, but I'd like to know which are exactly the modem files that I would have to replace and how I would have to do it.

I just want to know all the steps before starting cause I've upgraded my phone so many times and in all of them I had to go back with a previously done backup.
[Android Q&A, Help & Troubleshooting] ericp2:
Hi, check post #315 in this forum by Eryen. he provides link to TWRP-X2-CU_1520_modemfiles.zip, which you can install through TWRP (AP lollipop of course!). note that he provides 3 files in this update, but one of them does not change (so it does not matter).

I want to do a 100% factory reset with official rom. (VIBEUI_V2.0_11443_5.5.1_ST_X2-CU)

In Smart phone flash tool can i instead of " only format" the "format+download" to choose?

I make so a brick?
[Android Q&A, Help & Troubleshooting] ericp2:
If you started with a CU ROM, you only need "Download only", because the file system layout does not change. if you had installed an AP version, you must "format+download". in the second case, make sure you have backed up your NVRAM, as format will erase absolutely everything, including the NVRAM.
[Android Q&A, Help & Troubleshooting] djapor96:
Thank you!

So from CU to CU rom allow system to format, but unimportant.
[Android Q&A, Help & Troubleshooting] ericp2:
Hi, misunderstanding maybe? phone cannot function properly without a valid NVRAM (wifi, cell, bluetooth...) ! if you choose to format all, you will have to restore NVRAM. just making sure this is clear!

if you just want to clear everything, why not just to a factory reset instead?

Modem still not working!

Hi all,

My phone is still not receiving all the signals I received in the CU ROM.

I have:

-Formated and downloaded the AP lollipop S-223 ROM.

-Installed the OTA.

-Installed the right version of TWRP.

-Restored the NVRAM backup.

-Flashed the flashable zip containing the modem files.

And I still don't get the signal I had in the CU version.

If someone knows how to do it right, please tell me.

Found root method !!

Good Day to Everyone !! I have successfully root my device after research until i slept in front of my laptop.. Haha.. So now I'm going to share the method with you.. This works on VIBE X2-AP version and VIBE X2-EU version.. Actually the tutorial is for X2-EU version, but I risk my device by push it to my X2-AP version which is not in the original russian tutorial actually..

I have Lenovo X2-AP, Indian version.

I followed this procedure and successfully rooted my device. BUT.....

Now second SIM card is not getting detected :( Baseband 2 is dead. I think this kernel is for Single SIM devices. Any idea where to get kernel for Dual SIM Lenovo X2-AP?
[Android Q&A, Help & Troubleshooting] BardP780:
Ok, thanks for the bugs feedback.. Im currently using single sim on my X2-AP device, thats y i didnt notice that.. Yes, that possible to happened bcoz as i mention above, this tutorial is actually meant for X2-EU device which is Single Sim while our X2-AP is Dual Sim.. Unfortunately, there is no OFFICIAL STOCK ROM for X2-AP in any web at this moment.. In needrom.com also you will only found 3 stock rom for X2 which is X2-CU, X2-EU, X2-T0.. This meant that we the X2-AP user must live with this situation which is rooted device with only single sim support until Developers uploaded Kernel with Shell-Root for X2-AP.. However, you can try to find any custom Rom for X2-AP if available in order to get your Sim 2 working again.. And since u have root access, now u are able to Use MTK Droid Tools to backup your current rom before try to flash any custom rom.. Otherwise, if your phone bricked during Custom Rom installation, you will be not able to Recover back your device.. Congratulations anyway for your rooted device.. :D For me, I can live with single sim active.. ;)

Ouch.... you have bought the wrong device... X2-T0 is meant to be use only in China.. the 3G/4G network is based in China and only available in China..

Hi, there. This is no quite the place for my issue but it's somewhat related.

I am from Europe and bought VibeX2 CU version, i wanted the dual sim option. However i find the ROM despicable but that's in general.

I have the fallowing issues the theme center and few other places have connection to some Chinese servers and the third party widgets stop updating after few minutes. I assume that both issue are in due of the ROM is there a possibility to connect for instance the "Theme center" app on my CU version to the European one or i have to flash a different ROM. And for the second am i the only one experiencing this?

Apologies for the sorta of topic issues.

I guess it's because of locality of the existing (chinese ) rom.

So I have a Vibe X2 - CU (i live in canada and only poor cheap prepaid 2g so even one sim would have been ok for me).

I haven't been successfull to root the CU with your method.

First, i should learn how to read as i hadn't used the sp flash tool 5.1436 you recommended and in fact nothing happened (but something must have happened because i had to hold the power button 15 seconds in order to have the vibe x2 to boot again :D ).

Then I used the 1436. My phone was detected fine but i had this error message :

brom error s_ft_da_init_sync_error (4004)

fail to send sync data to da in initialization stage

I had again to hold the power button 15 seconds for the x2 to boot normally.

I have tried in admin mode, on windows 7 et 8 (x64), usb 3 and usb 2, with universal mtk drivers or not.

Too bad for me... luckily i bought the X2 because it's so beautiful (grey and white one) but battery life is abysmal to say the least. I saw on a russian forum that i have an updated rom for the CU but i won't try that as I have the french language and i don't want to have english or chinese only (but i have some menus items in english or chinese, it's kind of cute :P )

Try this:

-Open Windows Device Manager

-Plug your phone into your computer while it's on

-Power off your phone while it's plugged in

-See if you notice a device appear called something like "MediaTek USB VCom" or maybe "MediaTek Preloader Device"

-If there is a little orange exclamation symbol by it, quickly right click on it! Then, proceed to install the MediaTek USB Vcom Drivers to that device by selecting to manually search computer for the MediaTek USB VCom Drivers.
