HTC Magic Port Radio Issues (SOLVED)

(solution at the bottom of this post)
Hey, ive searched for a little while now and i havnt found a solution, so if i missed it im sorry just point me in the rigth direction. In the mean time, here is my issue:
Its the same issue with:
4.5
4.9
5.0
(these are the only onces ive used)
all downloaded from:
http://code.google.com/p/sapphire-port-dream/
now ive wiped before flashing each update, and even wiped after the update, ive even gone back to rc29 and then trying again
when i get the phone to finish booting up, my radio gives me issues, it will show full bars, then none, then full, then none, never showing edge, so i go into wireless settings and realize that every 20 seconds or so, airplain mode is coming on for a half a second then going back off, without me clicking it, but when it does this, it never shows the airplane icon where it does if i click it myself in the top status bar
now if i manage to dial out a call at the right time, it will keep the full bars, and dial out properly, i can have a half hour phone call or longer without a problem, when i hang up, i have full bars AND edge for atleast a hour or so, and then i drop edge all of the suddon and go back into the airplane loop, inwhich a simple phone call (even to voicemail) fixes it temporarily
this issue happens as soon as i reboot the phone as well, as it starts up, it shows no connection, then emergency calls only, then tmobile, and repeats
when under mobile settings when trying to select a network manually if im lucky for it to show tmobile and at&t, 90% of the time it tells me it cant connect to tmobile due to my sim. if i keep clicking it it will say registering to network, but it will stay in the loop with the airplane mode flickering on and off
again, if this is something stupid im missing, or if its been explained elsewhere, my bad just point me in the right direction, but either im not searching for the right thing or ive just completely missed it, either way, someone help me before i have to go back to JF 1.42, im really enjoying this magic port
Ok, so thanks to the suggestion to "update the radio" and Google for pointing me in the right direction. I did as follows, and so far, so good.
Download this file to SD card
http://sapphire-port-dream.googlecode.com/files/Saphire-Radio-Update (rc33).zip
Saphire-Radio-Update (rc33).zip Sapphire Radio 2.22.19.23
Rename it update.zip
Reboot Phone in Recovery
(I wiped, this may not be needed, but I did anyway)
Alt + S to install the update
the phone will ask you to do the home + back to reboot, press it and it will do a few other things, including reboot into a screen with a arror pointing at a microchip, then it will reboot back into recovery
hit the home + back yet again to perform another reboot and it will boot up normally and so far, ive yet to have an issue with my radio after this

wootroot-
THANK GOD I AM NOT ALONE!!!!
This problem has been plaguing me as well with all of these new builds!!!
Ultimately I ended up going back to JF 1.42 MOD because I needed a working phone.
I flashed to 5.0G tonight... and its doing the same thing... radio on then radio off. I tried flashing to the new Sapphire radio... nothing works.
I would love for someone to come up with a working solution.
Thanks!

i feel the same way, i thought it was just me
there has to be something im missing, so many other people use these builds without issues like this, there is no way someone could put up with this issue and use the phone as a daily phone reliably
if you want to have 5.0 (well i flashed H not G but im sure it would work regardless) time a phone call to your voicemail when your radio flashes on and when it vibrates saying the call connected, hangup, and everything will be fine for a few hours
do me a favor though, read over the stuff i just added to my first post, see if your phone is doing anything different than mine, that way when someone who comes in here and is able to help, they know exactly what our phones are doing, and hopefully its not just us with this issue and it will get others in the trend of explaining in detail what is wrong with theres, maybe this will help speed up getting a solution lol (wishful thinking?)

I am redoing things once again.... reflash, etc.
Keeping my fingers crossed.
But it's late and I am tired and annoyed.
If it happens again... I will try to make a video of whats happening so others can actually see it.

I thought I was going crazy I'm on 5.0G now the new one which adds busybox but I've been having the same exact problem as the OP but I haven't tried the Sapphire Radio yet but we all seem to experience different issues anyway.

no fun, sorry your having issues too, you say we are having different issues, could that be because we are using the HTC code and your using the GOOGLE code? or did i misunderstand you?
can you explain a little more about the sapphire radio vs other radios? ive been trying to understand what the difference is, and how to switch between them, but so far im unable to find a clear answer, so can you tell me the difference and how to switch between them?
thanks for your help
EDIT:
oh and what do you use busybox on the g1 for? i just read up on it (http://en.wikipedia.org/wiki/BusyBox) and i have a general idea of what it is now, but whats the use of it on the g1? do you use it as kind of a DOS for the g1? is it more for developers than end users?

This problem has happened to me but seems as all I needed to do was to reupdate the radio. It worked for me!

try reflashing the rom, then do the radio update

Hi all, I've just rooted my phone (Australian release on Optus) and i was wondering if the radio update has regional limitations or not? Because i've heard positive things about it but I don't want to screw my phone up.

Data keeps randomly disconnecting; radio update needed??

It's been happening for a while now. I can have full signal on H, then suddenly no H, E, or G. Data does not reconnect automatically; I have to force it by switching Airplane mode On/Off. I saw something in the forums about a radio update, but I heard that removes ability to change permroot/S-OFF. Please help me clarify this, and if there is an update, is it safe and should I install it.
Stock ROM, temp-rooted with Visionary and permrooted with HBOOT/WPTHIS_OTA method. Kernel is the one linked in my signature thing [1497KHz] and pushed Wi-Fi module. Hopefully that's enough info. Let me know if you need my SSN# ...lol

I have been experiencing this exact problem quite often over the last two weeks. I am using CM 6.1.1 in Chicago.

same situation happens to me...nvr seem to have a solid 3g/H in my house. While my blackberry will be having 3G all day. The g2 will fluctuates from H -> G -> E and stays like that. So annoying that ruins the experience of having a good data phone.

Same problem here! It happens from time to time, I have to switch off/on data to get reconnected.
Also happens when I turn off wifi after a long period of use, It won't reconnect to the carrier's data.

I had this when I switched over to CM 6.1.1. I thought it was CM so I flashed my backup, then decided to try it again. The problem I found was Pershoot's kernel. My data connection would drop and come up on it's own and was happening while I was using data. I've been running CM 6.1.1 with it's kernel and haven't had this problem since.

Same here running latest Virt (tmous g2) and I *think* it's running a pershoot hybrid.

I have never run Pershoot's kernel, and have always used the kernel included with CM. It seems to be recent (last two weeks) problem for me. The phone cycles from 3G->G->E->3G->H. The worst, however, is when it shows 3G->H but cannot connect to anything. The only solution is to turn off the data and let it reconnect.
I think it might actually be network related and not hardware / software. Maybe too many new phones activated around the Holidays? The reason I think this is that my Nexus One keeps having similar problems --- even on different ROMs.

Could be either?
I used to be on Mobilicity in Canada and experienced this (random disconnects from data several times a day, wouldn't automatically reconnect), switched to Wind and I haven't had this problem.
Stock G2 ROM, unlocked, s-off, su visionary

Data Problems...
Ignore my signature I'm currently on G2.
I think the problem you all have might be a TMobile problem.
I live in Madison TN / Nashville TN and I been having that data drop problem for going on a year now. Happended on every phone I been on Mytouch 3G Mytouch Slide Samsung Vibrant HD2 and now I'm on the G2 that I bought yesterday. Also had the same problem on a Nexus one.
The situation was that I will have all my bars and a 3G/H symbole and my connection would just fall a sleep with the 3G still in corner. Put phone in airplane mode and take it out airplane mode and my downloads will resume.
This process would happen after 15 min or 20 min of constant data.
2 days ago I started calling tmobile to get this fixed. Told them I didn't have this problem on ATT and Verizon so they put in a service ticket with the engineers and they claim it should be resolved in the next couple days if mot to give them a call back and to forward my call straight to level 2 tech support.
More people should complain about it.
That happended across atleast 5 different pda phones and 3 different sim cards. Yeah some of the phones had custom roms but each phone shouldn't have the same symptons.
The cellular towers in my area must really have a problem and I'm expecting a credit on my account lol.
PS connection is perfect on Edge though... Just slow...

Could it be because of overclock?? What if a certain CPU speed doesn't play well with the radio?? Just a thought...

For that to happen to me on 5 different devices that will tell you that CPU speed has nothing to do with it. Best I can say is to reset your phone to stock and give TMobile a call and let them know the situation. If you dont, nothing will be done about it.
I say to return to stock because if you dont, there reps will try there best to put the blame on you and the custom software. But from my experience being on Nexus One / MyTouch Slide / MyTouch 3G / Samsung Vibrant / HD2 / G2 all having the same exact problem????
Yeah the problem is on TMobile end...

Is it the same EXACT problem I'm describing? Or are you talking about general reception? Because some people on here with different ROMs (or radios) have mixed results. I'm in an HSPA+ area with full signal usually, but I keep having my data disconnecting. After a while it comes back, but I don't like to wait that long. I just switch radio on/off. :/

Yeah it sounds like the same exact problem to me which I had on all those other phones too. Im like you I dont feel like waiting so I switch to airplane mode on and off and the data comes back.
Or Il just drop to 2G Edge only and the connection is stable just slow though.
I couldnt find a solution online so now I got tmobile reps in the picture to get this resolved for my area though.

Count me in. I HAD a BB 9700 and it behaved the same way you guys are talking about but i didn't have to set it to airplane mode to reset the connection. I do however have to restart my G2 sometimes to get it connects to Tmobile network again. It is such an inconvenience.
I'm on stock rooted rom by fastludeh.

Yeah TMobile need to get this fixed. I plan on giving them a call back on Monday or Tuesday since my 3G connection still continues to drop.
Im currently on ALL stock on the G2. Havnt did any modifications yet.

Would changing the radio help? i see there is other radio firmware available...not sure if that will do anything for our phones. Currently sticking to my 9700 for now until this issue is fixed or if i get bored of the 9700 and jump back to the G2

Na I dont think changing radio will work. I tried multiple radios and custom roms on the HD2 and same situation over and over.

Having problems with everything connection on my g2 it started happening like two weeks ago. Random no service for like a minute then full bars and hspa never use to do it but now it does frustrating as heck oh on a stock froyo too wtf

HBOOT-0.35.0017 and 3g connectivity issues read here

EDIT: The problem is still occurring. I thought it was fixed.
Myself and a couple other people experienced stange 3g connection problems while running the cm7 nightlies (among other ROMs) with the new HBOOT-0.35.0017. I know it's been said that HBOOT shouldn't have anything to do with your data connection but nonetheless it is causing problems.

Thanks!

I'm sorry to tell you, but hboot has NOTHING to do with the radio part of the phone: it controls the system partitions table and boots the system... nothing else, it doesn't even touch the RAM parts dedicated to the hardware, the kernel does it.

I almost made up my mind to downgrade until seen the edit part. 3g part of signal is very very frustrating experience on my side while call part rarely let it down. Also signal always in close to100 reading while my Acer liquid on T Mobile stays to perfect 75-80 reading.

I'm on HBOOT-0.35.0017 and sometimes I get x gray bars but after it picks up signal and gets connect to H it seem to work fine. Until I lose the signal or I switch to airplane, etc. Takes a while sometimes to get back signal or the H.
I did notice that when the screen goes off my download stops or sometimes when I download certain files it stops right away. I been updating roms so not sure if it related to them, but overall its been like that.

yes screen off downloading stopping is quite annoying...

I dunno but since I upgraded my Hboot and used CM7... my data sucks. It will work then not work. I typically have to reset to get it back. Even switching in and out of airplane mode will not work.
And by 3G I mean my data connection. I'll have full bars and 3G coverage... but no data from the browser, no pings, no online apps, nothing. Seems like the only way to fix it is to reset the phone.
I also noticed my signal is noticeably less at home. Typically I have full bars but now I notice that it's been dropping out and bouncing.
Could be a carrier issue. But I haven't upgraded my radio since 5.08 first came out. I updated my HBoot for the early builds of GB. So I'm willing to test out this theory.

lol, hboot has nothing to do with the phone's radio. The radio version does.
If you're having a problem with the radio (voice/data) then you should look at the radio version you're running.
Again, hboot has nothing to do with your issue.

Ive had the data sticking problem since I got my n1. Remember reading somewhere that if you go into settings - wireless networks - mobile networks - network operators, when it finishes searching select "automatically select". I got T-Mobile & it works for me until the next time I flash a new rom.

FYI when I was on CM 6.1 I had your problems. I then switched to MicroMod777's Gingerbread and those problems disappeared. I've now flashed Enmother's TheOfficial Nexus1 and I'm testing. Absolutely a ROM problem.

Kinda the opposite for me. No data issues when i tried CM 6.1.1 but on MM Gingerbread i had no data connection at all!

Same here. I tried MM and nothing worked! lol. So I went back to the latest CM7 (#24). I'm not sure what the problem is. Now I'm on an older HBoot and an older Radio. I shoulda just left 5.12 and .35 on there.
Once I get my phone pieced back together, I may try one of the older CM6.1 roms to see if that fixes it. I think we are all using Gingerbread roms here, no? Perhaps that just is an issue that comes with it.

Same issue here, wondering if this hboot is incompatible w/ my old radio.
just received my new nightly, will give this method a try as soon as i upgraded.
thanks!
-- just saw the updated post, thanks anyway

Perhaps the OP should change the title and original message to exclude the HBoot details as the problem is with Data connection.
This will let us continue discussion about the data connection problem that we are, I am at least, experiencing.
Using CM7 #24 from 1/30, it seems to be less of an issue. I notice that I'll have 3G and full bars, but no data will work until it changes to an "H". Seems like it might just be the rom. The latest nightly seems to correct the issue better then before. Now if I open a browser, after 30s-1minute, it will start chugging along.

Sleep of death (SOD)

I have had a half a dozen totally stock mytouch 4gs that will run perfectly fine but about 4-6 times a day I will pull the phone out of my pocket and it will be totally unresponsive to the power and trackpad buttons. No led no button lights or anything. To get it back to normal I have to pull the battery and reboot. I just loaded virtuous fusion 1.0.6 and the problem persists.
I've tried factory resets, formatting the sd card, new sim card, turning off screen animations, clocking the cpu higher when the screen is off, and running with no apps and no google account set and none of that has helped. The only common thing between all the phones is my number and google account and it still happened after a factory reset without signing into google.
Has anyone else had this issue? Am I just extremely unlucky?
I just loaded loaded the 26.08.04.30 radio we'll see if that helps...

i posted this in another similar thread but still no answer, i want to know whats wrong! lol

I have seen this but not that bad, are you checking your phone constantly cause thats what happens to me. Lock, unlock, then the lcd doesn't light up but led, and buttons do, try loading the newest radio 26.09

At one point I thought that too. I thought "theres no way they sent me SIX dud phones in a row." So I wiped my sd card and did a factory reset without signing into google or anything and loaded no apps and it still did it.
I noticed though that when I pull my sim card out and use it in my other mytouch 4g(which works perfectly fine with that sim) this phone will not show this issue without the sim in it. So I started thinking it might be the radio as I've tried a different sim card and that didn't work.
This is my first day with the new radio so I will report back with my results.

Well that didn't work. It just SODed on me twice in a half an hour.
Should I try flashing the other radios or CM7 or something? I'm wary of flashing too much as I have the dreaded M4G2E emmc serial.

i also have the latest radio but still get this problem every once in a while, i almost wanna say i started noticing this after i started flashing different radios tho, first the 26.08.04.30 radio then the newest 26.09.04.26 radio

Maybe I'll try the oldest one then.

I noticed today that if my phone becomes unresponsive and I plug it in the charging light will come on and I can boot the phone without pulling the battery. It does a full boot too not a fastboot. For some reason though if I do this it will SOD on me way quicker than usual.

I think that is the issue your EMMC. I had this problem with my phone, then one time it happened when I pulled the battery it bootlooped and CWR showed me that lovely error... be careful. Wish we would know if your other phones had the M4G2E as well. My current phone has the other chip and I have never once had the SOD like I did on my old chip.

[Q] Random Reboots

Ok guys, I know that there are posts about random reboots but it seems non have a solid solution. My Hd2 has started doing these annoying reboots for about a week. I was using Tyweens NexusHD2 2.9 and all of a sudden reboots started. So I switched to Typhoon CM7 3.5.7(currently on phone now). Reboots still occur. So I did Task 29, wiped sd card, plus clean install of Typhoon CM7 3.5.7. Phone still reboots. It actually rebooted during setup. I even changed from Magldr 150/5(suggested) to 200/45 thinking it was memory related. Still rebooting. I have noticed it does it more when WiFi is on. Is there something with the latest Android 2.3.5 and Wifi? Any help would be greatly appreciated.

No not at all.

I'm having the exact same problem... but strangely now even when I try older gingerbread builds, it does the same thing. Its only been recently, too... I've had the phone for a while and I don't remember it doing this.
I can have the, same build and same gps libs on my wifes hd2, and hers won't reboot. Mine will.
I even went as far as swapping out my mainboard with another one I had from a cracked screen issue... and that didn't solve the reboots.
I can't figure it out. It must be gingerbread and certain phones. Ive tried 2.3.5, 2.3.4 and 2.3.3 and they all are now rebooting. I don't know why its only been lately, too. The, only thing that solves it for me is running Tytungs NexusHD2 ROM v1.9 Froyo based. I can even add the latest agps fix and don't have any reboots. Only thing I really miss from gingerbread is the DSP bass boost which makes a huge difference for my bluetooth audio via my car.
Remains a frustrating mystery to me.

I always set this as my default wifi policy since I am always connected at home. So that's a no-go for that tip. At least for me, personally... still reboots.

So far the only thing that works at home is to turn off 3g.
I am trying Rafdroid 4.2 and so far has not rebooted away from home.

Rafdroid is a Froyo based ROM - same with the NexusHD2 v1.9g build that I'm using and so far no problems.
But when using any gingerbread (sense or non-sense) / CM7 build, I am getting those random reboots. Sometimes so much to the point where the phone is unusable. Then there are times when I could go hours without any. I thought it was something related to 2.3.5 since that's right around the time things started going strange, but like I noted - I've downgraded to 2.3.4 and 2.3.3 - and the same thing is happening. I used to use Hyperdroid GBX 7 for months without issue... now when I load it, it gives the same result. Same with Hyperdroid GBX v12, Hyperdroid CM7, Typhoon, stock bravo based CM7 Nightlies, AmericanAndroid, NexusHD2 Gingerbread version or anything Gingerbread based - period.
It also seems coincidental that the reboots started right around the time when Tmobile issued a bulletin asking for user input about recent unusual high battery draining with mobile data. I really haven't followed up and I don't know if it was determined what was causing it for some users but I am thinking maybe it could be possibly related. I can't explain why my wife's phone can run the exact same ROM and not experience the same thing yet mine does. It seems like an isolated issue - I don't see a lot of people complaining about the same issue lately. Maybe it has something to do with a specific mainboard revision/manufacturing date and some kind of over sensitivity to mobile data power output or something. As I noted in the prior post, I did switch out the mainboard with another one that I had laying around. I did take note of the revision manufacturing date stamped on the board, and they were identical. And both experience the identical problem. My wife's HD2 was bought 3rd party from a private owner at another time separate from when the 2 HD2's I have on hand were purchased. Perhaps she has a different revision/manufacturing date.
The two mainboards that I am having a problem with have a date of 2010/03/16 - they are both identical.
I would take apart my wife's to check her date and am willing to bet it's something different, but I've had really bad luck picking apart these HD2's the few times that I've done it. I've broken wifi coaxial cables and ripped flex cables. The date is stamped on the bottom of the mainboard.

mine is the same, the only solution works is to turn off 3G, with all GB ROM I tried

I am wondering if specific phones that run Gingerbread are experiencing this lately because of this:

Like I noted - perhaps it has something to do with an oversensitivity to 3G mobile data power output, etc.

Same behavior here - had random reboots multiple times per day until I switched to 2G only (only adjustment I made)....have not had one in over 72 hours of uptime now.

Sounds like Bad Blocks to me. Happens to a lot of ppl, me included.
I have 4.

How would bad blocks be the problem if the solution is turning off 3G?

OK, I can now pretty much confirm my original hypothesis about the mainboard. I have switched it out with one that was manufactured in late 2009 according to the timestamp on the board, and that's eliminated this problem for a while now with Gingerbread entirely.
The exact problem is beyond me, but unfortunately I stick to my guns that it's a hardware issue. Not sure why it would affect Gingerbread so much more than Froyo but my guess would be it has something to so with mobile data power management or something of the sort.
So for those saying that turning 3G off counteracts this rebooting effect, try a good Froyo build to keep your 3G connectivity. The reboots didn't happen nearly as much as they did wile running Gingerbread for me (although I would get 1 or 2 every few days).
Unless you can get your hands on another mainboard... or another phone.
Replacing my HD2 entirely for now wasn't an option for me... it's the only "Android" phone that I can run with the grandfathered 5.99 Tmobile web. Any native Android phone is identified by tmobile from its IEMI and forced to upgrade to a smartphone data plan to work with mobile data. They just happen to allow legacy (less than WP7) Windows Phones work with that old data plan, which is what the HD2 is.

+1 switching to 2g sucks but works,my wifes hd2 works fine though like others have mentioned. this is crazy lol
BTW all these reboots stated for me when to mobile messed up their signals and was causing android phones to have high batt drain.

Where can i switched off 3G beacause i've the same problem with reboots?

I have notice mine does it when I am at home using WIFI and 3G is on. If I turn 3G off all is ok. When I am out and about I can turn WIFI off and 3G on and no problems. Wacky.

i had a similar problem on my hd2 tmobile with coredroid 1.6 on it..
Random reboots have become all too often, usually when i start applications and i did not want to waste any more time so I changed the rom...

I would get a random reboot every two our there hours until I took of all my widgets except for two and I haven't had a random reboot in about 2 days and I didn't mess with the 3g signals. but my phone still has battery drain issues
