[Q] Questions about unlocking, rooting and modems. - RAZR HD Q&A, Help & Troubleshooting

I'm sorry if this questions have been asked before. I read through many pages on the Q&A section of this phone and didn't come with clear answers to my questions.
This is the first time I will attempt to unlock, root and flash a ROM on an Android phone.
First of all, I've read and I still don't know if I can flash a custom ROM, or one of those Brazil/Orange JB images available and be able to have the phone unlocked to use with different carriers. Jelly Bean hasn't been released to this phone here in Mexico yet.
1.- I don't mind unlocking the bootloader with Motorola solution. Is this the best way to unlock it?
2.- Flashing a custom ROM or a stock one makes the phone unlocked so I can use it with different carriers?. If the answer is yes, what ROM do you recommend. Are those Brazil/Orange images good for any user or its better to stick with third-party ROMs?
3.- If the answer to number 2 is NO, what should I do in order to unlock the phone? I need to be able to use in Mexico (the phone if from Telcel) and also use it on the United States (with AT&T). I've read about modem files that had to do with carriers but I'm not sure if I need special files to unlock this phone? If this is needed, where do I start or where do I find this files?
4.- If there is something else I need to know (and I didn't asked here) about unlocking the phone and flashing a stock or third-party ROM and have it unlocked to work with other carriers, please let me know by replying.
What are you guys using to backup the factory image? I haven't fiddled with Android for a while after flashing a Kindle Fire many times. I got a Nexus 7 and I haven't needed to root, unlock or try third party ROMs. The last time I used TWRP to backup the image of the Kindle Fire I think.
Thanks in advance

Unlocking BL doesn't change the unlocked status of the phone for carriers. If you want to unlock it to use with different carriers you'll have to pay the unlock fee to whoever you choose to unlock with.
1. Answered above.
2. Custom ROMs or ROMs from different carriers won't unlock the carrier.
3. I believe there is some sort of file modification to have it unlocked. Not sure what you have to do but if I remember correctly its risky and affects IMEI.

I know the bootloader won't change the locked status. As this is the first time flashing a phone, not a tablet, I thought that using a custom ROM or one from different carrier would work for this.
I've tried other SIMs on the phone (it's my sister's, not mine) but the phone didn't asks for a code when a SIM from a different carrier is inserted. I haven't bought any code because of this.
Anyone has a suggestion on what to do to have the phone unlocked to use with different carriers?

How do I prepare my phone for roms?

I need to root, unlock, and install CWM right? How exactly do I do this? I tried to locate a how to without any luck.
The dev section is filled with all the info you need to know.
Also, not trying to be a **** but saying you searched when it is obvious that you didn't will get you nowhere.
OK I've read some more and had a couple more questions...
I noticed that the roms I've looked at don't require an unlocked phone. What's the point of unlocking the phone then? Can I just root and install CWM?
Some roms say "needs the 1.85 base." What does this mean and how do I get it before flashing a rom?
Thanks!

Some of the roms, prior to the unlock discovery, were executable as an RUU. All the updated versions require recovery which you need the bootloader unlocked to get in to. It's a painless process and there's even a 1-Click script method for those who dont want to take chances.
Will I be able to get the phone back to COMPLETELY stock should I decide to sell it in the future?
From what I know it will say relocked or tampered but maybe I'm wrong

After unlocking your phone, there will be no way to get back to 100% stock unless we can get S-OFF (which hopefully may be in the near future due to a few devices already being S-OFF).
However, you can root your device and not unlock it (1.82 and prior as of now) and still be able to revert to 100% stock as if it came right out of the box.
Most of the ROMs currently do not require an unlocked bootloader.
However, this will definitely change as we begin to see custom kernels (hopefully soon with the release of the source by HTC Dev) and more complex ROMs (such as those based on AOSP, such as CM9 and AOKP).
So in short, you can still use most of the ROMs in the dev section. Just be aware however that if you do not unlock then you cannot install CWM (limiting the number of ROM options) and also if you update past 1.82.502.3 then you cannot root (at this time, other root exploits are being explored).
Is unlocking your bootloader the same as carrier unlocking your phone?
Does this mean that say, AT&T phones could be used on Tmobile?

Nope. You are thinking of SIM unlock.
Bootloader unlock lets you load custom ROMs and change recovery, that's all.

[Q] question about firmware,root and unlock device

hi
JUst want to understand, when you root a phone ,do i need the carrier firmware (i think you call it roms)
Cause my phone was under telus and i just did the unlock by a web site and they me send a code...
My phone is under vigin now (unlock)
What do i need to root it , the stock firmware ,or the one from bell(since it the same as virgin)
I saw that link for the carrier firmware http://forum.xda-developers.com/showthread.php?t=1739426
after i root it, can i flash it to jelly bean
Thanks
nobody?
Your question is very confusing because of the English you use and mixed up terminologies, plus you don't even say what kind of phone it is. To root it, you'll need ADB or Odin. When you root, you will load new software on the phone, typically a ROM.
A Telus ROM is basically the same as ATT, GSM. You should start there and search for the right APN for your carrier.
Get CM10 for ATT. Then look up the virgin APN info. There are app store apps to fix/set APN info.
YouTube has video to show you how. Google for your answers.

sorry im french
but if im unlock why do i have to use a rom from virgin
Unlock and root are 2 different things. Unlock (or SIM unlock) means you can use your phone with any carrier. Root means you have access to all files on your phone (this is like being "administrator" in a Windows computer, as opposed to being a "limited user" or "standard user"). To use the iPhone analogy, rooting your
Android phone is like jailbreaking your iPhone.
So, what do you really want to do with your device? I'm guessing you want to put JellyBean on it. If that's true, you must:
Root your device
Install a custom recovery
Download a custom ROM which was designed to run on your device
Use the custom recovery to install the ROM onto your phone
thanks
But if i dont want that triangle ,i gonna use that method http://forum.xda-developers.com/showthread.php?t=1739426
And my phone was under telus and i have unlock it to use it under virgin.
I gess i have the rom from telus!!??
So i root it with the rom from telus or bell(virgin)????
And after that i can put jelly bean without tripping the counter.
Thanks
OP, not sure what you are trying to accomplish by your title in your post, but seem you have the answer/method you are looking for..
Thank You & Thread Closed

[Q] Newbie again

Hi guys
I am new and never flash firmware on HTC before.
I have go HTC one XL from hongkong unlocked with JB (just recently got the official download) but not happy with the data connection speed and it is very slow for some reason. ICS was better than the Hongkong official JB release unfortunately.
Since I am in Australia I want to flash my firmware with the stock rooted Telstra [ROM] 01/01/13 Stock rooted odexed JB Telstra_WWE_3.17.841.2.
Can some one pls point me to the right direction - I am not sure where to start (previously I own SG2 and flashed firmware no issues).
I am aware that there are more options on how to flash in HTC I am abit worried that I might follow the incorrect steps
Thank you
Unfortunately, some changes were deployed in the official JB update which causes the touch screen to not function if you try changing to any ROM that is not also Sense JB. So currently, if you flash an ICS ROM, the touch screen will not work.
Devs may be working on this. But its more likely that it won't be solved until we have kernel source for JB. Until the issue is fixed, you are stuck with Sense JB ROMs.
If you still want to be able to flash custom ROMs, the proper sequence is:
- Unlock bootloader at HTCDev.com
- Install TWRP recovery
- Download custom ROM, and copy to phone's SD
- Flash ROM in TWRP
- Flash boot.img using fastboot

You need to read until it makes sense as a complete newbie will just end up bricking the phone.
You do need to unlock the bootloader. Your phone may be "unlocked" in relation to allowing any SIM from any provider, but that is 100% unrelated to unlocking the bootloader.
The Telstra 3.17 is unlikely to make any difference to the Hong Kong based 3.17. They are almost identical except for the few Telstra apps included.
Have you checked that your APN is set to telstra.wap so that LTE will function? The Hong Kong phones ship with incorrect settings for Telstra.
You could refer to this link for help, but ignore it's advise to set telstra.internet as that is incorrect(it is only for 4g modems, not phones) and will prevent some Telstra apps from working correctly:
https://support.mobicity.com.au/ent...up-the-htc-one-xl-on-telstra-s-4g-lte-network
Also you should check Telstras coverage as LTE is only available in limited areas.
http://www.telstra.com.au/mobile-phones/coverage-networks/our-coverage/mobile-broadband/
Beyond these suggestions you should take up your speed issues with Telstra.

I already answered this in post #2 above. Don't know why you are asking the same question again.
Twisteddx beat me to answering your other questions, and I agree with all he said.
You're confusing unlocking the SIM versus unlocking the bootloader. SIM unlocked just means you can use SIMs for any carrier. Bootloader unlock removed write protection for certain partitions of the memory, allowing you to install custom recovery, custom ROMs, etc. SIM unlock and BL unlock are not related in any way.
I'm not a huge fan of simple tutorials. They invite you to try mods with a minimum of knowledge, which is really the opposite of what you should do. Read up, and learn as much as you can, as twisted mentioned, you will be performing things that can cause permanent damage to the phone if not done completely properly. You need to have a deep understanding of what you are doing before you start. Even if you follow the steps to the letter, things all-to-often go awry. And being armed with as much knowledge as possible is the best way to prepare for such events.
The amount of information can be daunting, for sure. But once you become more familiar with the terms and basic concepts, you will probably see its actually not that complicated. Maybe start with some of the "Misc Guides" at the bottom of the 1st post of my Index thread, such as the Terminology glossary. Look at other posts by similar users in Q&A, and go from there.

What do you mean by saved cid? Is your phone carrier locked? Or what are you trying to say? You should pick a stock fw, which is at least your country/region better also from your carrier. It may also not be available at the site i mentioned.
If it is not available you could try and make a request. See the op of this thread
There is no such thing as an "unlocked bootloader" XT910 nor any other OMAP chipset Motorola device unless it is an engineering model with an NS bootloader.
There is no OEM unlock available for those devices and there never will be as the bootloader was never designed to be unlocked.
Motorola themselves have stated as much publicly.
This person has wiped their CID. partition in order to successfully flash a firmware from a different region onto his device.
He should seek advice in the proper forum fro those who have experience with this type of cross flashing issue.
It is precisely as a result of the locked bootloader status of these devices that these kinds of issues arise when users attempt to update their device with firmware not intended for their specific hardware or regional configuration.
Uh thanks for the heads up, wasn't aware of that. I assumed that motorola devices would be all similiar with this.

Tips: What is unlocking the phone?

Some people may have doubt about what is unlocking the phone. At first I mistakenly assume that Unlock is refer to unlock the phone screen. It's very clear now that it is not true.
Q: So what is unlocking the Phone?
A: There is a lock inside the phone that stop people from using the third-party system or what we said custom ROM. (Although many phones are using the Android OS, the system in different brands are not exactly the same. In order to keep the unified feelings of their brands, the manufacturers prevent users from using custom ROM. That’s why they set the lock. )
Q: What is the use of unlock?
A: You can use custom ROM after unlock.
Q: Will it brick the phone if unlock failed?
A: Unlock failed has no effect on the phone. If there are some problems during the unlocking process, just take out the battery and restart your phone.
All of these statements are based on personal experience, if wrong, please specify, thank you for your read.
Purpose of unlocking the phone is to use it on another network

:good:Thank you for your add
Most of the time when it's unlock you can use it with many different carriers check GSM and non GSM carriers, Carriers like verizon, sprint have there own bootloader (Brand Image upon starting) and a secure stock rom. So it somewhat difficult to root there devices, Like my verizon S6 I've been waiting since the OTA update.
