Lenovo X2-CU -> EU flash

I have Lenovo X2-CU version.

In my case, it was simply flashing it from the Flash Tool. But the problem is that there is no data connection available. I'm going to try to change the modem files and see if it functions.
[Android Q&A, Help & Troubleshooting] Yoshi_Guy:
File differences

First of all, I would like to thank you IMMENSELY for enlightening me about putting some files into the /system/etc/mddb directory. Previously, I only knew I needed to change the modem file in the firmware directory. This worked, but only gave me 2G STILL after the baseband was recognized. I'm hoping changing these files will work and give me 3G like I had on my X2-CU ROM. Now, to the question: do I need to copy all of the rest of the files in the modemdb folder of the downloaded ROM with similar file names into the mddb folder or just one file?
[Android Q&A, Help & Troubleshooting] eryen:
just because of these are totaly same device you can copy all file in those folders, but basicly changing

/system/etc/firmware/modem_1_lwg_n.img and

/system/etc/firmware/catcher_filter_1_lwg_n.bin

is enogh

These are my test results

EU modem files uses only two frequencies as we compare CU modem is nearly universal :D

CU-1520

EU-S223
[Android Q&A, Help & Troubleshooting] Yoshi_Guy:
So basically I don't need to change any files in the /system/etc/mddb directory? Also, I had previously done the steps you mentioned and only got those two 3g bands recognized from the EU ROM. However, despite using the X2-CU's modem files we STILL can't get the other 3g bands to work? By the away, I read somewhere that restoring the NVRAM (Or something in the NVRAM) of your X2-CU to a X2-EU can unlock the other 3g bands if you have replaced the correct modem files. Is this true?

Rooting EU Lollipop version

A few days ago I changed the CU KitKat ROM I had to the new EU Lollipop ROM posted here, but I had a preblem with the bands received, so I asked here and I was given a solution to the problem. The thing is that I had to have my phone rooted to fix that (I had lost my root permissions when flashing the new ROM), and I didn't succeed to do it, even though I tried with: Kingo Root, Kingroot, iRoot, vRoot, Root Genious and even with MTK Droid Tools. Does someone know how to root it in Lollipop version?

PD: As I didn't succeed in rooting the Lollipop version, I went back to the KitKat CU one with the flashtool and, surprisingly, I was able to root it with KingRoot.

So finally after searching for days on end I have finally found a backup of the Vibe X2-AP ROM. It can be found here with instructions: goo.gl/TxiAa5 I wont be able to test it for the next few days :/ It would be great if somebody else could test it and let us know if it works :)
[Android Q&A, Help & Troubleshooting] ibaitxozk:
Problem with bands

I just changed the ROM from my original CU ROM to the Lollipop EU one, and I have succeeded to root it. The thing is that there is no signal on my SIM card, and I've tried some things like:

-Restoring the two files in the firmware folder (from the CU ROM) that previously in this thread were mentioned.

-Restoring the WHOLE firmware and mddb folder with the files from the CU ROM in which I had vey good signal reception.

-Restoring the NVRAM folder.

Any of these methods worked (I restarted the phone to apply changes every time I did a new method). Could anyone tell me what did I do wrong?

Apart from that, when trying to enter the engineer MTK mode from Mobileuncle Tools, I found that I could only enter the Android mode, in both CU and EU versions. But, I downloaded in an app which sent me directly to the MTK engineer mode and I could enter it.

The problem is that, when I was trying to enter the BandMode, I couldn't see anything in the EU ROM (not in the CU ROM, in that one I can enter normally), I was kind of blocked and I couldn't see if I had those bands.

Hope someone helps me and many other people out.

Thanks in advance,
[Android Q&A, Help & Troubleshooting] Yoshi_Guy:
What you forgot to do was chmod 644 the files you copied over. Without this, the system can't read the files you copied which is why they are not appearing. To chmod the files, install a terminal emulator from the Play Store (Doesn't matter which, just a terminal emulator). Then, attain root permissions by typing "su" (without the quotes) and pressing enter. Then, grant the root permissions.

Next, you need to change to the directory of which the files are stored. The commands for this are:

"cd /system/etc/firmware"

and later:

"cd /system/etc/mddb"

(The cd command stands for change directory fyi)

Once you are in the directory you need and you have root, type "chmod 644 insert_file_name_here" (Replace insert_file_name_here with the name of the files you copied)

Once you have completed this for the firmware directory, exit the app and repeat for the next folder.

You're done. ;)

Ap devices has different scatter file. For example in eu rom, system partiton located in mmcblk0p14 but in ap version it is located at mmcblk0p6 or 7. So update script can not mount system,data and preloader partitions properly.

Unless we have a correct ap scatter file you can not convert your device to ap %100. You can only update via modified update scripts. Ota will never work properly.

Rooting is simple, because of unlocked bootloader.

Flash TWRP recovery, after that supersu. Thats all.

ATM, there is no custom rom for Vibe X2, because of there is no too many MT6595 devices at market (Middle=>High spects). If somebody have skill and time can port Meizu MX4 (Flyme OS) rom, which uses same chip, basicly it would be simple to convert, but should be tested properly.

[Android Q&A, Help & Troubleshooting] t3ntacle:
Yes, you can install X2-AP on CU, but you have to full-format the device, so first you have to backup your nvram partition (otherwise you loose the IMEI and other hardware identities), then flash with SPtool.

After that restore the nvram, and you have to use the modem firmware (copy from CU rom /system/etc/firmware/dsp_1_ltg_n.bin to dsp_1_lwg_n.bin, and catcher_filter_1_ltg_n.bin to catcher_filter_1_lwg_n.bin) for mobile network get working.

Then your phone will be a X2-AP device, and OTA updates will work too.
[Android Q&A, Help & Troubleshooting] eryen:
Modem files replacement is not necessary if your operator uses 800,850,900,2000 mhz 3g network.

I have also a CU device, and fully converted to AP rom.

There is no problem with our operators in my country. All of them uses 2000mhz 3G network, so did not touch to any other files after installing AP rom.

Just dont forget to backup your nvram partition as t3ntacle mentioned, or you will loose imei and all other hardware related configurations.

About rooting.

yes you can easly root your device after you flashed twrp recovery.

even you need to flash twrp recovery before flashing AP rom to backup your nvram, and flashing twrp to restore your nvram on your device.

while you are at twrp recovery, you can install supersu binaries easly.

I've specially checked twice if, this rom is ota suitable. Even i have updated to lollipop via ota files as official way.

Install the USB drivers for your Lenovo phone from here: http://www.mediafire.com/download/krejvwb0oap26nv/LenovoUsbDriver_autorun_1.0.15.exe

Then, plug your phone into your computer and see if you see any files.

---------- Post added at 08:04 PM ---------- Previous post was at 07:56 PM ----------

What t3ntacle says is partially true. You do have to copy the files and full format your device, but you do not need to copy THOSE files. As I live in the U.S., I need the CU model's modem because my carrier uses the 850 and 1900 mhz 3g bands. The ONLY files you need to copy are the modem_1_lwg_n.img file (located in the /system/etc/firmware directory) and the catcher_filter_1_lwg_n.bin file (located in the same place.) If you copy or replace any of the other files you will not get the Modem change to work. (Trust me on this, I have done it 10 times wrong by copying different files, THOSE ARE DEFINITELY the ONLY files you should copy.) After you have copied the files and backed up your NVRAM, then install the ROM and restore the NVRAM and the files from TWRP. After you replace the files, be sure to run the command "chmod 644" onto the files you copied. (You can do this from TWRP by using the file manager again and then tapping on each of the files. There is an option to chmod 644 there. Do that.) Hope this helps. I converted my X2-CU to X2-AP for a full English translation and I changed the modem files because the X2-AP version modem does not have the 1900 mhz 3g band, which my carrier uses (like I said. :)

Hope this helps and is informative!

Download the Smartphone FlashTool from this link: http://www.mediafire.com/?u69gmmt8u4zjfi3

- Open Flashtool and select the MT6595_Android_scatter.txt file ( in the folder after you extract the zip with TWRP in it) under the button that says scatter loading

- Wait for the file to be added into Flash Tool

- Open in Flash tool the Options / Options / Download and select DA DL All with Checksum

- Turn off your phone.

- have to set " "Download only", but do not use "Format All + Download", because you will lose the IMEI

- Press Download

- connect your phone into the computer via USB data cable.

- install the MediaTek USB vcom driver if you haven't done this before (Let me know if you haven't installed those drivers, they're different than the ones I sent you)

- The process will start and a red progress bar will appear after, yellow, grey and green circles display

- Finish !
