Is it safe to mix radios? - EVO 4G Q&A, Help & Troubleshooting

Dumb question, but would it be fine to keep the newest PRI/PRL, and other software updates but flash older radios?
I was just a bit worried about any incompatibility issues. With the latest updates, my 3G cuts off more frequently.
I did not do any explicit testing but I remember being able to hit 2.5 Mbps while tethering on older radios, now I only hit about 200-300 kbps.

I would advise you not to flash radios once you have the newest. I believe it will brick your phone. However I could be wrong.
Sent from my PC36100

I remember downgrading used to brick the G1's or was it the spl, or both...I forget.

I've been told unequivocally (though I haven't actually tried it) that flashing any radio will NOT brick your phone. I remember asking when I was going to upgrade, because if I ended up with worse signal I wanted to be able to come back, and several power-users said it's no problem. At least nothing beyond the normal danger of flashing radios. Never pull the battery, radio flashes actually reboot the phone before they finish, sometimes more than once.

i can also confrim that flashign a radio will not brick your phone if done properly. when the radio with the 1.43 came out (seem sliek forever ago now) many had issues with Mac addresses etc and rolled back.
Now i will say that some roms may not work with older radios. I beleive that if the rom is based off of a certain update it may need that radio or newer as well but i cant confirm. All i can say is you should be ok to flash an older radio and see what happens and unless something has changed since 1.43 to cause your phone to brick you should have no issue doing so.

Issue with Radio Upgrade

My radio initially is the original official radio, but then I want to upgrade to it 1.17.25.09.
Then I read some post saying that I should downgrade it to 1.02.xxxx or below, then I can unlock the security lock.
However, I think I misunderstand it and just downgrade it by flashing the radio, I think I am supposed to flash a rom which has an old radio with it.
But lucky that time I was able to upgrade it without security unlock my phone.
Now I just flash the radio 1.17.25.09 straight away, and now my radio is 1.17.25.09.
However, there is a little problem now.
I wasn't able to connect to the wifi internet I usually connect to, is it the problem of the radio? or is the problem of the ROM? Can I do some test to ensure my wifi function is correctly working?
Just one more question, what does the flashing a new ROM affect/change the performance of the phone?
Many thanks for reading this long thread, hope I can get some answers
I think the wifi Problem is a Problem of the rom, because 2 years ago i put a new rom on my htc wizard and then i was no longer able to connect to my home network.
Hope i was able to help a bit!
Thank you for your reply, I will try to flash a new room tonight and see whether it is functioning

Orange de-branded, updated radio, GPS broken

Hello all,
I'm aware there are a few threads of people complaining about GPS not working when updating/unbranding an Orange branded handset (more specifically the radio). The solution seems to be downgrade the radio (which is more of a workaround than a solution). I've been wanting to try out one of the recent Froyo with Sense ROMs, this includes 720p video recording (and something else). The radio must be updated for this to work. I've tried the new radio and it breaks my GPS (left it outside for 10 minutes, it used to fix within seconds). Has anyone had any success in getting the GPS to work without downgrading the radio?
Thank you, Rowan.
Okay, been nearly a month and quite a few views but no replies. Even with the latest radio GPS still never fixes. Has anyone else had any experience on this?
I'd say the easiest fix would be to shove re-flash Froyo on there and if necessary unlock your phone with a code. Failing that, root and install an older radio via recovery. I haven't seen this issue anywhere else.
I've already unlocked it. As I said in my first post I want a newer radio to try out 720p recording and such so downgrading the radio isn't really a fix. I can only think it's Orange's meddling as GPS works fine with one radio and not with another so it's not like a fault with the actual phone :/
What radio version are you using?
I'm running a de-branded Orange phone on the OTA official Froyo ROM and it's all working fine. The baseband is:
32.43.00.32U_5.09.00.20
I did just try that one you mentioned and it didn't work. I used to use 32.30.00.28U_4.05.00.11 as my radio that GPS worked with (I tested all newer ones and no GPS). Now that doesn't work either so I'm a bit miffed.
Edit: Okay that does work actually, I'm guna play around a bit. I'll get back to you.
Edit 2: Okay, I've played. It seems it's actually a problem with Google Maps as the Compass app works fine.

N7100XXUEMK9 official rom... Lots of problems

My sister's Note 2/N7100 got notably worse after getting official android 4.3 update N7100XXUEMK9: battery life is almost halved, and wifi connection is very unstable, with lots of disconnections and week signal strength. None of this happened while the phone was on official 4.1.2. I think these problems might be related to the radio module, and flashing an older, known to work, version might do the trick. But flashing the radio requires rooting, flashing custom recoveries, and such, and i've read many scary things about Knox. Is it possible to downgrade only the radio module without touching anything else and without tripping the Knox flag?

Pretty sure Wifi is completely separate from 3G radio.
I suggest you perform a factory reset from within the phone settings. That really helps after major updates. Note you will lose your data, backup to PC or SD card your photos music etc. Plus of course your apps start from scratch too.
MKp is old news now. Consider rooting and putting a newer factory image e.g. NA1. If you decide to do so, you have much reading ahead of you!
Good luck.

Problems installing Sense based roms

For some reason, every time I try to install a sense based rom, it never boots.
I'm fairly new to flashing, and have flashed 4 or 5 aosp roms. Every time I install one of those, it always works correctly, no issues.
I have tried to flash several Sense based roms, such as ARHD 20.1, Insert Coin, and nv, and each time, it never works. I always do a factory wipe beforehand as well as a wipe in the aroma installer. It will go thru the process and install, and then prompt me to reboot, which it does. Once the screen comes back onm however, it just hangs on the white htc screen with the red development text. When i get back to the hboot, itll show nothing for os.
I thought the issue may be that i dont have the latest firmware, but even people that dont have the latest firmware still are able to boot into the rom. Also, I just tried the NV rom which is based off my firmware, and it still gives me the same trouble. Does anyone know what I'm doing wrong?
I'm running an ATT Htc One m8, rooted, unlocked, s-off with sunshine, twrp recovery

Give the ROMs about 10 minutes, and I bet they will boot. The extremely long boot time, and lack of boot animation (another symptom of this issue) makes a lot of folks believe the phone is stuck/frozen, when in fact its just taking a reeeeeally long time to boot.
If its true that the ROMs in fact never boot, it might just be an issue with your recovery. fastboot erase cache and either re-install recovery, update to the latest version, or try another recovery (Philz).
Even if the Sense ROMs boot, you might find some serious things are broken with your outdated firmware, such a broken WiFi. So I suggest either update your firmware or stick or ROMs based on your present firmware.
Ok thanks, i will try again. Ive read a bunch of threads about updating my firmware but couldnt find an answer to a question I have about it.
If I upgrade my firmware to the latest WWE 3.28.401.6, will it mess up my ATT settings like the bands? Also, will it erase my internal sd card?

Firmware includes the radio baseband, so it may cause issues with reception on AT&T. It seems at least a couple folks have been flashing the 3.28 firmware, but I haven't seen enough reports to give me a warm and cozy feeling. With S-off (which is required to flash the firmware, anyway) you can always revert. But still, basic reception is more important to me than a couple updated features. Personally, I'll probably wait until the 3.x firmware specific to AT&T starts rolling out.
It seems like the M8 is radio agnostic like the Nexus 5 based on my experience.
I am on Rogers and flashed the latest firmware and my LTE works no issues.
The latest firmware is supposed to be EU so technically those North American bands are not supported but it works no issue.
Leads me to believe that the radio does not matter like the N5 where the 820 and 821 radios were interchangeable.
HTC One M8
Thanks redpoint, you were right, I gave it some time and it did come on. You always seem to be the one answering my questions, I appreciate it.
As for the new fw, I was thinking that would happen too from what I've read, I just needed someone more experienced to confirm that. I think I'll wait as well.
Thanks again

On the 2.x firmware, some folks in North America (I can speak mostly of AT&T specifically, although there are a lot of network similarities with Rogers) had varying degrees of issues with the "international" firmware. For some, the reception was worse, and others had NO SIGNAL whatsoever. Probably depended on what bands AT&T was using in their specific market.
Can't say whether 3.x firmware is the same way. But in my experience (or at least, reading reports by others here), I would have to disagree this phone is in any way "radio agnostic", at least from a software perspective (as the hardware is common among at least GSM versions, and baseband software is the only difference - but that is a slightly different topic).
So what is the latest firmware I can flash that's been known to work? I've seen that viper one is based off the 2.xx fw so do you know of anyone who's flashed it with att variant without any problems?

For the record, I have an AT&T model and am using the 3.xxx.xxx.6 firmware with absolutely Zero issues as far as signal. I get the exact same reception I did stock, and Very, Very similar reception to what my old Optimus G did in the same locations.
This indicates that there must be either a difference in hardware revisions (related to how some M8's can be firewater'd, whereas others need Sunshine), Or, the int'l radio firmware may not support the bands that are used on some towers in some locations. I'm leaning toward the former. For the record, my M8 is a "whelp", and I had to pay for Sunshine.

My guess would be the former as well. Keep mind that AT&T uses five different bands for LTE depending on your market region. Also keep in mind that travelling to another location may result in losing LTE reception (when you otherwise would have LTE on a AT&T specific radio).
Although none of this explains why I've seen some folks get NO SIGNAL whatsoever on AT&T's network after flashing the international firmware (2.x version, haven't seen any complaint yet on 3.28). Even if no LTE, those folks still should have been able to get HSPA and/or GSM since those AT&T bands appear to be supported by EMEA specs. So it leads me to believe there is something else going on aside from just band compatibility. Such as the network not falling back properly to HSPA/GSM.
I certainly don't have an issue if folks want to experiment with the 3.28 firmware on the AT&T network (as long as you know what you are doing, and are aware of the possible issues). Its certainly tempting with the 3.x based custom ROMs coming out. I might even experiment myself if I free up some time. But that spare time is a bit of a premium for me right now; and I also can't really afford ATM to have the possibility of reception issues or no service.
I was able to successfully upgrade my firmware to the 2.xxx by using skull dreams' method. As soon as my rom loaded, however, WiFi and data weren't working. I read through the thread and found that clearing cache and dalvik would fix it, so that's what I did and it worked. (initially I tried to wipe both at the same time, but it gave me errors; further reading showed I needed to wipe cache first and then dalvik).
I would now like to upgrade to the 3.xxx fw so I can install arhd 20.3, but want to know, if I upgrade my fw and it messes up, can I just do the same renaming and putting it on ext SD card to downgrade back to the 2.xx fw?

You could always restore the backup you should be making before you do any mods on your phone. That would be the safest way.
So if I upgrade my fw then restore a backup, I will lose my fw changes?
I make nandroid backups before I do any, so I have approximately 60gb of backups on an external HD, and I always keep 1 or 2 on my internal and external storage

bandwidth connectivity issue, (installing new radio possible fix)

i just encountered this issue the last few days and continues even after installing a new rom. im having trouble downloading files online or apps from the play store, its almost like the connection keeps getting disconnected and reconnected. im also having a problem playing a small online game called spades that worked fine a few days ago. its a card game so is not graphic intensive or take up alot of bandwidth.
another issue that ive just dealt with for months is rarely getting LTE data even though i should be getting according to the coverage map. im usually in wifi so it doesnt bother me too much but it got me thinking maybe i should look into installing another radio/modem which could possibly fix these issues. my current baseband is UCUFNJ2
You're running the latest modem for this phone, so there's nothing newer available. People have hard bricked the i747 on newer firmwares getting the bootloader and modem unmatched, so you have to be careful. We used to think the bootloader couldn't be downgraded at all post Knox, but it turns out you can downgrade as long as you don't go back a major version. There's a set of odin flashable files available. That's the only confirmed safe way I know to downgrade NJ2. Since you're already on NJ2, you have to stick with a 4.4.2 modem.
Safest thing to do, if you want to try out a different modem and just give the phone a fresh start would be odin back to stock NE4 4.4.2 using the files you can get from here.
From there you can test drive NE4 and see if it works any better. If you leave it stock it should offer to OTA to NJ1 and then back to NJ2 too, letting you fairly safely try out all the modems left available to you.
