Hi people,
this is my first post here
i'm from Mexico and my Razr HD is from Telcel
after flash the Retail Brasilian Firmware I lost my 4G LTE because the firmware has a diferent modem from Brasil LTE
for the people who lost LTE after flashing (like me) I have the solution
I just took the firmware from Rogers Canada and extract the modem_signed file and with this modem I have again my LTE from Telcel
I attached the bat file and fastboot files if somebody need it
i didn't attached the modem_signed file because my internet is very slow but you can download it from here
http://forum.xda-developers.com/showthread.php?t=1943879\\
you just put the modem_signed file in the same folder with the files attached and run the bat file, your phone need to be in fastboot mode

well, with the brazil firmware you will no have any app of Telcel and the performance I feel it a little bit faster but not much, the only thing that will not chance is the Messages icon because its stored in the sim card, if turn on your phone without your sim card you will see the original Message icon (blue) then if you insert your sim card the screen will be flash a little bit and the Message icon will turn orange with white

Ahh ok. Well I've read that removing all telcel's stuff was a huge improvement on the speed/battery life.
Maybe I will try this on the weekend.
Gracias!
Just to let you know, this does not work on CM10. It makes the modem unstable, and can't connect to LTE.
Anyway, thank you for your help.
hey
we can also flash the rogers firm full, just download from firmwares thread and open the firm file with winrar, choose the xml file and edit with notepad, erase the following lines
<step var="max-download-size" operation="getvar"/>

Telstra 4.1.2?
Does it have any bloatware?
I´m having issues with my phone since new. If I have LTE after a call my signal dissapears for a few seconds and then reconnects. This doesn't happens with 3g.
Is there an error with the original modem file from telcel?
My phone is damaged? I'm the only one having this problem?
Saludotes!
Can't get lte working on this thing now m matter what, ClaroPR works with the 700mhz frequency

For my use Iusacell Network, I have preferences to Custom Roms or Cooked (still there for the Razr I) and therefore I did the following:
1. - Unlock Bootloader (Motorola Official Site)
2. - Install CWMR (Clock Work Mod Recovery) and made a backup of the system is Telcel see post of http://forum.xda-developers.com/showthread.php?t=2166646
3. - Download and install RSD Lite 6.1.4 http://www.mediafire.com/?yw9dh89jtqii71e
4. - Download and install a firmware using RSD lite 6.1.4, I chose Brazil Retail (ICS and is used to put a new SIM to exit the menu to enter the unlock code SIM) (It should "just unzip" by rsd lite in the browser and edit the XML file and delete this line <step operation="getvar" var="max-download-size" />
leaves the file saving changes in RSD Lite is sought file you edited and select to trigger the flash, if you choose a firmware starting with CFC this line does not appear, I not flash CFCs.
5. - I got the unlock code by IMEI (unlock code generated must be 16 digits) in http://www.unlockunit.com/es/liberar-motorola/motorola-razr-i-xt890, I want to clarify that the total amount was paid 19.9 USD as the price of 13.9 is on your list of search operator Telcel and when they do not, so it has to build and cost me, 6 USD I made my transaction via PayPal but you can pay online (takes 5 business days)
6. - I put the SIM of Iusacell, asked me the code, I introduced and ready, Razr I working with Iusacell (the Razr I in the HSPA+ Iusacell network is 4G)
Note: You can start from step 3, and not supporting anything and just install a new firmware for you to quit the input menu unlock code SIM: good:
If you unlock the bootloader you can follow this XDA thread http://forum.xda-developers.com/showthread.php?t=1936512 very careful with the steps, you are to read

Almost do not understand what you write (and I quote above) has purchased 4 codes and none has worked for you ......... so far he had not seen it written, but at least many have been served and have their Telcel RAZR I bought running in Iusacell, could not even remotely help you with your case, which is very rare ...... but I would recommend requesting a refund of your money.

THANKS!!
If you are asking about the version that is on your (new) phone. Go to settings / more / about device
You will also see your model number. Just filter your model number and you can download the appropriate official firmware.

I only put error because I don't really know what else to call it. Whenever I use my tablet and I play a game that required me to hold a button down for a period of time, it lets me hold it but then just stops responding to touch until I lift my finger up and place it back down again. Does anyone know why this is happening and if there's something I can do to fix it? If it helps, I'm using the 7 inch version and although I'm running a custom ROM, I've had this problem ever since I got it.
Hey, I just bought this tablet to test my game and I have the same issue. It happens to me with games like "league of evil". I'm touching the move buttons while touching jump or punch and the move buttons stops responding until I lift my finger and press again.
Also I've setted debugging options to see touch presses and the touch is not registering.
Any hint on why this happens or how to solve it?
Hi sorry for my bad english im from México and only speak spanish. I have the same problem , i think is a touchscreen problem.my cuestión is: if a got root and calibrate with an app that can solve my problem? Is a regular problem in this tablet? I have sm t230 wi-fi model ,no root and stock 4.4.2.
Enviado desde mi MotoG3 mediante Tapatalk
I think this problem affects all smt230 but still don't know if it can be fixed. Maybe with the next os update?
Español:
Creo que este problema le afecta a todas las smt230 pero todavía no se si tiene arreglo. Capaz en la próxima actualización del sistema?
Never happend to me in games like modern combat 3,4,5 and order & chaos online, been holding move stick for 15 mins in row and never got timeout for touch. It must be because of app not the tablet, if its tablet try installing other ROM or factory reset.
Hi thelous, I'm interested in what you've responded. You have smt230 wifi only model with stock firmware? I'm downloading order & chaos online to test it.

Hi.
Sorry for my bad English, it's not my native language.
Ask for their help to know more about the 3G and 4G connection bands.
Buy a lenovo z6 pro, the 8gb / 128gb version, bring the bands B1, B3, B5 and B7. In my country (Mexico) the operators use the B2 and B4, but in some regions they are testing the B7. I decided to buy it because where I live my Xiaomi connects to the B7 but now that I have the Lenovo it seems as if it could only connect to the 3G. An operator (At & t) also uses the B5 for 4G but does not connect to it, only 3G.
There have also been many problems with the roms of the Lenovo team since they sell a version as global but it is not, it is only a hybrid version with deleted Chinese applications. Therefore it follows that there is no global version. I don't know if these problems have to do with connections.
Annex two images where I show the Xiaomi that connects to the B7 and what an application of the Lenovo tells me.

My phone is with CN 11.0.575 and parched with the ZaZz version (The .bat 00_flashrom.bat anywhere), i already have TWRP Recovery and now is rooted with Magisk.

I dont know, but i want to try with that ROM. I just can with the CN 11.0.575 ROM, i areally want to try with ROW, im using QFIL 2.0.1.9 .
Hello
I have very similar problem in fact the same I believe
When I start or recieve a call my current 4G full signal strength connection drops immediately 3G and the signal strenght become very poor. On the other hand while surfing on the internet there is no quality drop.
I have run a diagnistic test to my sim card and I get an error. I hope you have any information about it.
I am currently using 11.0.325 ST Global ROW. But on official stock rom the situation was the same.
It seem you have the Volte option not activated.
Check in your setting or maybe not activated by your operator ( turkcell by your mcc)
But i cant read turkey , i let you check that.
It's not a band issu, because you have 4g before call.

I've got the same problem in Russia. If the 4g is strong enough, then, the incoming call is OK. If the 4g signal is poor, or there is 3G or 2G signal, then when I answer phone the other side does not hear me, because my phone's microphone doesn't work. The problem is in the proximity sensor. To solve the problem you need to use to install Truephone app, and switch off the pre-installed google phone. Truephone does not switch off the screen. Another solution is to install 575 CN firmware.
Hi. Do you have the VoLTE function active? You can see it with the menu on call (*#*#4636#*#*). What ROM are they using?
I am from Mexico and in the network provider I am only receiving H+ (It is 3G but faster). My problem is about the bands. Because if my previous cell phone connected to the
Band 7 in 4G, this does not.
And I haven't had the problems they mention. If I have little signal, the call fails me; but if I am with 3 or more signal intent stripes, it works perfectly. I have the ROM 11.0.325 ST

Try to use Signal Network Guru app. There is an option to activate\deactuvate the bands manually.

I also have problems with 4g connection (it always stays at two bars of H+, Vodafone network,EU), can anyone post a tutorial how to solve this ?!? Also the person I'm talking to WITHOUT headphones hears me really bad.

Hello everyone.
I bought a chip that uses band 2 for 4G and I bring 2 chips. Since I have one of them when it warms up, an x begins to appear in the signal and does not recover until I get into airplane mode or restart it. But the strangest thing is that when I play and the cell warms up, they both start to fail, as well as Wi-Fi, they turn off and turn on, until it appears to me in the bar as if I didn't have a SIM and the Wi-Fi also turns off. when I had a chip that never happened to me.
Do you have any idea why it is? And why when the cell phone heats up does that happen or will it be the other SIM Does anyone else happen to this?

I applied your solution it helped thank you. But it is not fully solved. I tried all roms ( official, Zaza version, global version) but the problem always exist. Can we fix this sensor or the problem is about the antenna?

Yes, we (4PDA Russian community) are close to solve it. We found that the problem is in EFS partition. That partition contains the info about all kinds of phone's networks and IMEI also, and we have an opinion that only 575 CN firmware is totally ok for the sensors and antennas. So it is a great idea, but it has not been tested yet. For the first you need to install 575 CN via QFIL, 2nd - to install TWRP, 3rd - to backup the EFS partition via TWRP. To save that backup on SD-card. Then install the global firmware (the latest 375, for example)? TWRP again to restore the EFS from backup. It has not been tested yet.
