[Motorola Droid RAZR] Ohmster:
thomasmolover and others, I would like to help you but I am not an expert at all things phone, tablet, and Android. For me, I wanted root. Found that with root I could pretty much run all over the phone, nothing was off limits, and this would certainly have some kind of benefits that others with stock firmware from Verizon or other carriers do not have. So root was my first, big quest. I learned a lot by doing that. Installing drivers, using cables to connect to laptop or PC, using programs like Oden to push roms and data onto the device and install it. My favorite is Linux because drivers are never an issue, the phones and devices natively connect to Linux as if they were part of the system. Windows was a different story. The samsung Keis driver would not install properly at all, the Motorola drivers did install if I got the right ones, but they often installed things I did not want like MotoCast and other junk software that I do not need at all. Dropbox automatically uploads pictures and video, what do I need Motocast for? Syncing music to the device maybe, but if I wanted a music player, I would have bought a music player, this is a super cool smart phone, not an mp3 player. I think I got lucky the first few times with my Droid X by installing superuser or root apk files and installed them, but that did not last long.

Verizon, Sprint, AT&T, or ANY carriers DO NOT WANT YOU TO ROOT THE PHONE! So, they make the process very difficult or impossible if they can. Many computer and device owners are not exactly brilliant people. They do what the device offers, enjoy it for what it is, and pay extra money to turn on "cool services" that they want like Mobile hot spot. For Verizon, that is $20/Mo whether you use it or not. They fill it with bloatware or "junk" like VZ Navigator that will be a GPS unit for your car to get you to your destination, for about $4 each time you use it. Why in hell would I want to do that when Google Maps does the very same thing, is MUCH more updated and accurate, and are free? With a rooted phone, you can turn on the mobil hot spot, use it to your hearts content, and cannot be billed for it because the phone company has not idea that you are doing this or any way to track usage for billing.

I make friends here and on other forums. We talked. They loved to talk about the newest or coolest ROM they installed to change the phone and how much better it was. They sent screenshots. The phone was cool alright and all that junk/pay software from Motorola, Verizon, or anyone else was gone. Good riddance, not only less useless clutter but more free card space. It took me a while to build up the balls to ROM my phone or tablet. I think I did the tablet first because I need my phone for work and daily use. If I mess up the tablet and have to try again, not a big deal.

You will be able to tell who is experienced and very good at this by their member status and by the way they talk. Try to make good friends with one or two of them. Let them show you some of the ROMS they installed and courage them to talk about what is good about it. People love to talk so if given the opportunity and an audience, they will talk. I cannot believe that some of these ROMS will turn your beautiful Android phone into an iPhone. If I wanted and iPhone I would have bought one. So make friends, talk to them. Learn from them.

The tablet I have, Samsung Galaxy Tab 2 10.1 I rooted of course, then tried CyanogenMod ROM on because their seemed to be a LOT of support for it and development work going on. Now that my devices are rooted, I installed and purchased Titanium Backup and ClockworkMod ROM Manager. Both essential, both free, but the small amount you pay for a lifetime license is well worth it. With ROM Manager, you can totally backup your entire device, play with it, change it, mess it up, and always restore your backup to "put it back right". WOW! Same thing worked on the Droid X, but not the Razr Maxx, you must use Safe Strap for that.

Now that I have the confidence to change the entire operating system and if I don't like it or mess it up, I can easily restore it, I can start experimenting with ROMS. The Tablet was first, it does not have a "radio" in it because it runs on WiFi, has no carrier or monthly bill. The phone was a little more scary because I read in these ROMS that some of them have problems with "the radio" (The part of the phone that connects you to your service) so I stayed away from those. I finally installed CM10.1 on the phone and it wall worked great. I now have Jelly Bean, it is smoother, nicer, slicker, and works better if you do not get a buggy or beading edge ROM. And holy crap, you can customize just about *anything* on these ROMS, not like stock "Stock is frequently called blur" firmware or ROMs.

Now I want CM10.2 on the phone and Tab to get Android 4.3.1. I now use Safe Strap instead of ClockworkMod ROM Manager on the Razr Maxx because CWM will semi-brick the phone and it will never boot again unless you reinstall the entire ROM from a computer. Safe Strap does away with all that by letting you flash the ROM and gapps zip files at boot time. I heard talk that the radio and phone service did not work on the CyanogenMod ROMS anymore because they do not work on CDMA base radio anymore and that is what the Droid Razr Maxx uses for the phone. I installed it and the gapps with Safe Strap, keeping my original rooted stock blur ROM available and during the setup process, had to turn on the wifi right away and get it connected or the setup could not continue. Uh oh, looks like I will not have a working phone if I do this and for sure, data only, no more phone. I wiped CM10.1 off the phone and went back to rooted stock. But I did ask about CM10.2 on this phone and not being able to use it as a phone anymore. Being nice here paid off. Someone told me that of course it works, but you must change the radio settings under the settings menu.

/System Settings/More/Mobile Networks/Network Mode/ and choose CDMA + LTE/EvDo.

I did this, got back my signal strength bars, but no more 3G or 4G indicators anymore.It now also says LTE over the bars and works just fine. I did not have to reboot or anything, just make the change and try it out. Works great! I love CM10.2 because now you can get a free CyanogenMod account and get updates OTA just like the old days. These ROM updates are rooted so you never have to worry about losing root, and are slick as hell. But to get this stuff, you must use the NIGHTLIES builds, not the stable ones. I would swtich back to stock blur for daily use and then reboot to CM10.2 for a while until I became comfortable enough with it to try using it all the time. I had some issues, apps would stop, it would get stuck once in a while, but for the most part, all was well. But there now were updates in the System menu, I applied them and the phone only gets better. I am happy.

This is how I got my introduction to rooting, ROMMing, and customizing my devices. I know nothing about China Telecom, what exact type of device you are using. (Mine is a Motorola Droid Razr Mazz model XT912) Chances are that you will not get much help in this discussion because it is very specific to China and China Telecom. I would recommend that you make a new post, explain your situation best as you can, give exact brand, make, and model number of your phone, and the service provider you use. A couple of screenshots of the About Phone section always helps. CM ROMS offer the option for screenshots in the power press menu. Take some shots and post them so others can see what you are working on and with. They may ask you to go to different screens and take more shots to share. I attached a couple of screenshots of About Phone from 10.1 I have laying around to show you how to attach screenshots.

My best advice to you my new friend is to start a new post specific to your particular issue. Include important information in the title such as "China Telecom Razr Mazz XT912 with CM102" or whatever your ROM, model, and issue is to attract the attention of those that can help you. It is not likely that someone with a Chinatelecom issue will wander into this post and have the answer you want, but stranger things have happened. Make your own post, include all of the details that matter, and find people that who have been there, done that, and can really help you.

If you find this answer really did help you, please click the big "THANKS" button under my name. Good luck, this CM10.2 is good stuff, even though I have already updated it twice already. :fingers-crossed:
