Can someone please provide the HOW-TO restore back to the original Radio Version, original Locker or unlocker and original software available at HTC. (The files would be enough and a brief walkthrough) - I was able to change to 2.2.61 and it works fine but I am going to sell to someone and want them to have the original ROM so no issues will arise. Thanks for all your help!!
No Takers?
No suggestions?
a little more info please
Need to know what carrier your unit is for. If Sprint then it is pretty easy, but Verizon will require a little care as the files are not on the utstar page and the ones I have for it are untested as I have not tried the rollback.
so if we go to custom rom/radio with an unlocker all we have to do is reflash the sprint rom if we are on sprint?

Yes.. the Sprint ROM's available are complete ROM's with IPL, SPL, Radio, OS, ExtRom, etc. The Verizon ROM's are not available anywhere! Someone over at PPCGeeks claimed to be a Verizon Tech and said even they didn't have the software (which contradicts a user report where they say they walked into Verizon and walked out with a newly flashed XV6800). The available Verizon ROM's namely VZW_2.09_RUU_Signed.NBH is an OS only ROM. It's even got a CID of SPCS_100 which is wrong. IIRC Verizon has a CID of VZW__001.
Anyway, I bricked a XV6800 the other day because I didn't downgrade the radio before running TitanRelocker. The bootloader would not accept any NBH's except the Sprint ship ROM which of course would not load because the Vendor ID didn't match. If you have an XV6800 you should be a little more careful with updating the ROM's since we do not have an easy rollback method like Sprint users do!
Sprint!
Figured it out! Thanks it was a Sprint - Now I feel more comfortable trying different rom's out there...
could someone please point me to a thread that explains how to upgrade the stock 6800 for verizon to one that support rev a and internal gps that is reliable...i know i need dcd something probably and the sprint newer radio but am unsure of correct procedure and order thanks....just want to do it once...
hey
i believe i follow the thread below but am not sure of which order...thanks
http://forum.ppcgeeks.com/showthread.php?t=17667
thanks and info
thanks...i had to follow a slightly diff procedure for verizon...had to run 2.40 unlocker first...then sprint upgrade to latest official without customization...then latest dcd...then call verizon to activate...then turn on gps in phone settings...but works great...thanks...
HOW TO FLASH DIFFERENT REGION ROM ON T-MOBILE PROTECTED?
advice, please.
You CANNOT flash ANY stock rom from ANY other region onto your tmous.
If you do, it WILL permanently kill it.
Your only choices are the tmous stock roms, or find a tmous compatible custom rom that includes your region.
Search for a tmous compatible rom HERE

Stock ROMs from the HTC site or from a different carrier could brick your phone ...
Custom ROM is the best way to go ..
You will find TMO compatible ROMs in the TMO section, but there are quite a few that are TMO compatible that are NOT listed in the TMO section, one of the biggest things is to NEVER never never, and did I say NEVER , flash anything with a x.xx.51.x radio to a TMOUS, also I think there is a 2.05.50 radio that is just as bad.
So if you flash a radio just stay above 2.08.50.xx and you should be ok ...
Back in the pre-pudding days, flashing an AT&T radio on an International Atrix was a bad idea. Now that our bootloaders are unlocked, is that still the case? Is the worst that can happen a soft brick, or are there harder bricks waiting to happen?
It's safe to fastboot protocol with RSDlite. I did it the other day tryng a newer radio sbf. Worked fine. The problem from what I've been reading is downgrading to a previous version after updating with OTA.

im using at&t radio cwm flashable on a custom at&t 2.3.4 rom now with ram-fix kernel on my asia retail model (international). works fine so far. or if you don't want at&t radio you can try bell's latest radio as well. both works fine for at&t rom. for me at least.
you can download here att radio or bell radio
Hi Pennzoilgtr
Can you tell us exactly what rom - radio etc you are using and links to them if possible?
I have an international and find that custom roms are hard to find as most are for AT&T.
Thanks

i tried Alien by kp and nCrust both works.. for radio as long as you use AT&T rom, you need to flash att or bell radio in order to work properly.. att radio.
and flash this unified international o/c kernel with ram-fix all CWM friendly. works perfect with my asian atrix.
Thank you pennzoilgtr. will try cherry now...
I just got a new unlocked AT&T M8, switched over from iPhone. I'm going to be using it with T-Mobile, and I'm still struggling to learn how all this stuff works. So the phone is running on Android 4.4.4 currently, and I want to install a custom ROM on it, but I need Android 5.0. Since I have a T-Mobile sim card, I don't have any OTA updates. From what I understand, if I wanted to switch to a T-Mobile ROM, I'd have to pay $25 for Sunshine, which I'd rather not do. Would I also need to do so to get an international ROM? Also, from what I'm reading, my other option is to use the AT&T RUU from HTC's website to update to 5.0, and then install a custom ROM from there. Is this correct, would that remove my unlock, and are there instructions/recommended readings before I try anything? Thanks for any help.

You probably want the T-Mob radio software, so you can enable the 3G and LTE bands used by T-Mob. Otherwise, you will find that the AT&T radio does not give you 3G and LTE in many locations.
In order to flash another carrier's radio, you need s-off, and there is no way around that. Then you need to change the carrier ID (CID) and model ID (MID) to that of T-Mob.
At that point, you may as well RUU to a stock factory T-Mobile software image (not just the radio) and that would be recommended, is it will get you a complete T-Mobile "baseline" phone as opposed to an AT&T ROM with T-Mob radio, etc.
After running the T-Mob RUU, your phone will be "fully converted" to the T-Mob version in terms of software. Others here have converted the AT&T version for use on T-Mob. So I'll try to find one of those threads instead of trying to explain it all again.
None of these mods will change your SIM unlock. That will remain unlocked.

Another point: You can update to the latest AT&T Lollipop software by RUU. And you can flash custom Lollipop ROMs after that. But neither of these will enable the 3G and LTE bands used by T-Mob. So that is why I suggest "converting" the phone to T-Mob stock software instead.
Thanks for the response! Appreciate it. A few more questions, since I'm not sure I fully grasp the concept of radios.
If I first flash a T-Mobile ROM, and then install a custom ROM, is that any different from updating with a AT&T RUU and then installing a custom ROM? Will I still be missing the bands?
If yes, then should I just stay away from Custom ROMs all together? Is this a problem because I bought an AT&T phone?
Thanks again!

Yes it's different the AT&T ruu won't give you the T-Mobile bands. And you can install custom roms if you want but I would reccomend paying the $25 to s-off and fully converting to t-mobile and either stay on stock or flash a custom t-mobile rom

I think your first phrase was intended to read "flash the T-Mob RUU, then install a custom ROM".
The radio is not contained in the ROM, and flashing a ROM doesn't affect the radio in any way.
The radio is contained in what many folks here called the "firmware package" or firmware.zip; and it can be installed by flashing the RUU.
Another thing that will help you understand, is that the phone has something like 36 (or more) partitions. The ROM is just one of those. The radio is a separate partition (as bootloader, recovery, and others have their own separate partitions as well). Flashing one partition, does not effect the others. The RUU is a complete software image that flashes all the partitions to factory stock for a certain carrier version.
You can also flash the radio or firmware.zip manually (without flashing the whole RUU). But my personal recommendation would be to baseline to a fully stock T-Mobile software profile, since you are on the T-Mob network, to make sure every partition plays well together (as opposed to mixing T-Mob and AT&T software components).

I wouldn't say that. Custom ROMs have their place. But a custom ROM will not open up the T-Mob bands. As mentioned, you can only do that by flashing the radio, which isn't affected by flashing the ROM.
After baselining to a T-Mob stock config as I've suggested, you can feel free to flash a custom recovery and flash custom ROMs if you like. But if would be for other reasons than the radio bands; such as performance, customization, debloating, etc..

Basically yes. If you want to be sure a phone works fully on a certain network "out of the box", you should buy the phone that is branded for that network. Otherwise, you should always thoroughly research a phone (not branded for your carrier) before trying to use it on your network.
Luckily for you, on this device the radio bands can be changed in software using the mods I've noted above. On past devices, the band support was set in hardware, meaning where was no way to change it in software. In that case, you would really have some buyer's remorse to deal with.
Ah OK thanks for the responses! I think I'm starting to understand. I did research how an At&t m8 would work with T-MOBILE but I didn't realize i would have to go throw this whole software process to make it work! Anyhow I appreciate the help and I'll buy a Sunshine license when I get a chance. Thanks again!
You are quite welcome.
