[Q] Is region cross flashing safe? - HD7 General

Hi!
[Q1] I wanted to know weather it is safe to flash an Asia ROM to a Europe device or vice versa. My WP7 is not carrier locked and has the ROM flashed detailed in my sig and running smooth. I was searching the fora for this answer but I could not find a Yes or No answer for it. So if I want to flash an Asia ROM for my phone will it work? (Why: higher version numbers might have more stability and radio version might improve GPS signals, etc.)
[Q2] What is the difference between ROMs for different carriers (O2, Telstra, TMO, BellMobility, etc)? If I flash one of these will my phone still connect to my service in Hungary? All of them has different version numbers and radios.
[Q3] Can I mix radios and ROMs as well?
[REQ] There really would be nice to have a wiki or guide with these questions detailed or a HowTo for beginners. Most of us is really a beginner with WP7 I think not mentioning flashing a WP7 device. I have experience with WM6.x.x flashing but only flashed my HD7 once.
Regards,
Cina.

[Q] Milestone with US ATT Custom ROM

I have been looking for an answer to this and if it has been answered before, point me to the thread.
I'm using a Telus Milestone here in the US with ATT. I have GOT OR 2.01 loaded on my milestone and it's rooted in everything. Now the next step would be to pick a firmware for 2.2.1. However, There is nothing listed for ATT or US at all for that matter.
Should I use Telus's Firmware? And will it still work with ATT? I want to load some custom roms, but I'm a bit stuck. Thanks for any input.
You should use Telus firmware. Or any firmware you like, but flash Telus baseband on top in order to get it working on AT&T
Check in milestone Android development thread, there are few choices available (roms), pick one. There is still no official Froyo rom for Milestone though. Most of the custom roms available are nearly fully functional.

Thank you very much. I wanted to try it, but I didn't want to guess, be wrong, and be screwed. Thats all I needed!

[Q] Unlocked Tmobile HD2 - custom ROM

Dear Friends
I am using unlocked Tmobile HD2 in India
Now if I flash it with custom ROMs will it again lock it to the Tmobile network
Please help me friends if some precautions to be take for flashing
Thanks
No, dont worry, once unlocked it cannot be re locked.
Do NOT try to flash any stock roms except tmous stock rom. Example never flash the stock India rom,,, all stock roms will destroy your phone. Only use roms that say " tmous compatible," or "leo1024" or similar.

Thanks samsamuel...but mine is Tmobile UK with 512 mb flash size
If I flash the official Tmobile UK ROM..will it relock itself
Thanks
Ohhhhh right, in future don't say "t mobile hd2", its unnecessary, confusing and you will get wrong advice.
also, this "t mobile" section isn't for you, its for t mobile USA, which is kind of a different phone.
Answer no, it will never be re locked.

hd2 rom update
Hi, i use an US t-mobile HD2 in Hungary. Its unlocked.
ROM version: 2.13.531.1. I like to update the rom to 3.14
I found on t-mobile's site some instructions, and the new rom.
My question is: when i update ROM with original t-mobile ROM(3.14), can it be re locked?? Thanks (sorry for my bad english)
No it will not be relocked by flashing a new ROM (stated many times in many threads including this one)
If flashing you would be best looking at Energy 29017 custom ROMs unless you have a very good reason to want flash original ROM.
Custom ROM is superb & functions far better than any latest operator build.
I had T-Mobile 3.14 & flashing to Energy 23699 build ROM is like jumping forwards 2 years in software development (probably closer to a decade at MS development speed)
i have been using maglr 1.13 i think im locked out now i open up a daf an it reads Readme.txt for this release is missing.can someone steer me in the ridgt direction
Steer yourself at Google and type "magldr rearmed.txt missing", loads of results.

Upgrade GTS5570 to Gingerbread on carrier based phone

Hello!! I am just trying to find out how we can unlock the phones that we bought from different carrier providers and how to upgrade them manually...
Since, I don't have a carrier based phone, I'm short of ideas on this topic. So, is there anyone who has upgraded to gingerbread in a carrier based rom, please make sure you reply with all the details.
Also, I especially want to know about upgrading in a Vodafone - Italy galaxy mini phone. If anyone had tried it please share it here.
Thanks!!!
Hey
I have a carrier based phone (Comcel in Colombia) and I upgraded to GB without any problems (I used ODIN to flash GB).
SIM gets unlocked due to the fact that the whole filesystem gets rewritten, so I'd say that there's no problem in flashing different version of the OS on carrier based devices.
The only way that would be a problem is if the carrier has custom apps that report back (kinda like Verizon does in the US with some HTC devices).
For the Italian Vodafone, sorry I can't help you with that

Okk so you mean you can now use sim card from any provider after you flashed gb.... Also, will it have any effects on the performance of phone and what will happen if teh carrier gets to know about it???

Yeah, phone's now SIM unlocked, regarding perfomance (besides the obvious Froyo to GB performanc boost) there's no discernable change, there shouldn't be any change unless you're flashing a non-compatible ROM (EU rom on a 5570L or viceversa).
I'm not a lawyer but from what I've heard the only way a carrier can find out that you have a custom ROM is if you take your phone for repairs and all they can do is void your warranty, nothing more, althought I'd check the service contract in case there's something hidden in there.

Couple debranding questions

I've currently got a working gold card for my ATT HD7S. I'm able to flash any ROM (including the 5.x Europe ROM).
First question: other than the ATT ROM, which STOCK ROM would be most appropriate for a T9295?
Second: This will sound paranoid, but I'm concerned about the different modem/radio. In terms of interference, I don't want to do anything dangerous or illegal. Could flashing a European T9292 ROM to my T9295 create any issues in this regard? Maybe enable bad WiFi frequencies, broadcasts, etc.?

Why are you wanting to flash a different stock rom? What would be the advantages?
I've flashed the DFT rom to my HD7S and not had any issues.

I'm actually considering flashing the T-Mobile ROM. Reports over at Microsoft Answers suggest that the T-Mobile update has fixed the Zune Music freeze problem. It's driving me nuts, and I'm never expecting a fix for the HD7S...
Based on the speaker/call quality issue, it's pretty obvious that they don't care about major functions being broken on this phone.

Also, DFT is based on the generic Europe ROM, right?
Still wondering about this. Are region specific settings like Wifi channels dependent on the ROM or the device? Will an American device with a European ROM use Wifi on channels 12-14 (against FCC rules)? Surely not? I'm only asking because I read somewhere that using channel 12 might have been causing WiFi ICS issues.

[Q] Kernels and Firmware and all that?

Hey up chaps,
I've been on the site for a while and really enjoy the contribution that all the developers and everyone makes. I've mostly read stuff and never really bothered to make any threads or anything, as everything on here is self explanatory.
Anyway, I was just wanting a bit of clarification really. I've read the threads about flashing a new firmware, and the stuff about kernels, but I still have a bit of an issue understanding it all, and how it would affect me.
My understanding is that the firmware controls all the basics of the phone, like touchscreen, microphone, speakers, radio and all that stuff. And a kernel controls the way in which it works. Is that right?
I got my HTC One last August, and then unlocked it and rooted it, and then I put the Viper Rom on it, I think it was last updated to 4.3 Android OTA, the phone is an unlocked european (international) model.
I've often contemplated making the phone S-Off as I believe that gives a few benefits. Would I need to do that to put the latest firmware on it?
Would the latest firmware available on this forum make much difference to my phone? I don't have any concerns with it at the moment, but I'm always pleased when its updated and things work better or there are new features. How would I go about doing it? Would I have to wipe everything, and put a stock HTC international ROM on it to be able to update the firmware? Or could I flash it like I would with a ROM?
I'm not a developer or anything, but I can figure some things out with a little instruction.
I'll include the numbers in the bootloader in case anyone can advise me whether its worth upgrading the firmware/and or flashing a kernel.

Thank you for any help you're able to give, and sorry if this is basic stuff and sorry if its something simple. I've had a look here: http://forum.xda-developers.com/showthread.php?t=2485651 and found it a bit confusing.
Would something like this website be a good first step: http://firewater-soff.com/ ?
Oh, and I have TWRP 2.6.3.3 and Viper ROM 6.1 at the moment. And I upgraded from the standard network unlocked ROM, it wasn't branded or anything when I bought it originally.
My build number is listed as 4.19.401.11 is that something that is related to the ROM or the actual phone? I was under the impression that it was the latter. http://forum.freeware.info.pl/gry/gothic.html
Is anyone able to shed any light on this for me? Thanks a lot.

S-off is good, very good - get s-off before you update to hboot 1.56
will you see any improvements with a new firmware ...probably not
not much changed between 4.3 and 4.4.2 firmware wise

Thanks for that. Good to know. So the best bet sounds to go to s-off and then I can wait for some more developments along the lines, if there are any. I doubt it as this is now an old model.

Yeah. I've been using sense 6 happily on Viper Rom. I don't know whether the incremental android update would make much of a difference.
I heard someone saying that an updated firmware would improve the battery life. I've been looking at that firmware thread and still can't get my head around it.
Firmware varies on performance/battery life. Having the latest firmware might not positively effect your device in terms of signal strength and battery life.
For example I have an AT&T One on their network I always try out the latest firmwares available across the board. Some improve network performance while others drain my battery very quickly and any combination of either or.
If you notice some Carrier Updates include different radio versions when compared to another carrier with the same Android/Sense Version. Those carrier specific firmware updates are released in favor of their network. Not always do the carriers release optimized radio firmwares.
I've tried firmwares releases for the European unlocked HTC One that worked better then a firmware AT&T released.
In the end firmware updates (Radio updates specifically) are a trial & error process of finding out which one works best for you situation.
Kernels on the other hand are in most cases better as they are released. Since they offer bug fixes and performance updates and sometimes offer feature updates that come in handy down the road. Running a custom rom you will use the kernel that the developer choices, some use stock kernels since they offer the best stability. Others recommend using a custom kernel since they offer more features like 'tap to wake' or under/overclock of cpu and gpu... etc
Just like firmware updates, kernels are a trial & error process. Some offer great performance and battery life when combined with particular roms and settings, while others are horrible.
In the end its all a matter of what you prefer and the combinations of radio, firmware, roms. What works perfectly for me might not for you so take suggestions from others with a grain of sand. We don't live with you and don't do the things you do. You might love playing games or taking pictures, while I simply like to surf the web and email.
What you said makes perfect sense. Thanks for that. I do a variety of things on my phone, not one thing over the other, so I'll get the phone s-off and then try out the latest firmware I think. http://m.freeware.info.pl/indy-cat.html
So I'm now S-OFF, and I've updated the bootloader to remove the hboot developmental red warning.
Whats the best course of action now? I've looked into radios, but not sure where I stand with that. My phone is an unlocked international model, and I'm in California on T-Mobile. Would putting the t mobile radio make much difference? Or should I just go with the latest firmware? From what I've read that includes a radio.
This is the latest firmware I would flash isn't it?

Many thanks for the help.
Using T-Mobile radio will benefit you since there tailored to US side of things, but you won't know until you try... Those zip aslong as they have the radio.img and the text file you can delete all the other things if you wish if not just flash them all.

Thanks for that. I'll give that a go tomorrow and see what happens. I don't really have any problems with signal, and I know as my phone is a uk model there isn't any chance of me being able to utilize the 4g network. http://online.freeware.info.pl/shakes&fidget.html
Hello again,
I'm looking at this thread:
http://online.freeware.info.pl/klondike.html
and I'm a little confused about which radio I should put onto my phone. I'd like to give the T Mobile US radio and firmware a go but there are a couple of different ones listed in that thread and I'm uncertain about which to go for.
Thanks for the help.
