[Q] How do i downgrade to KB2 radio? - Nexus S Q&A, Help & Troubleshooting

can i do this even tho i am running stock non rooted??? If so please can someone tell a newbie how to do this

From my experience, I wouldn't try it. I attempted with my ns4g something similar and the radio stopped working. I had to flash back to factory stock and call my carrier to reset my account. Since you're not experienced in doing this, I'd suggest not doing it. You can easily get yourself in a situation that your phone will be not working anymore and then you'll be back here asking us how to fix it. I'm not trying to be a ****, I'm just saying that it's not a good idea to try this.

It's not really hard to do. You just flash a flashable zip or setup ADB and flash the radio image.
Is there a reason why you want to downgrade your radio?

Yes i have this stupid search button bug and its unbearable. I heard a new radio fixes the problem

Search button? Radio wouldn't fix software.
Radio is responsible for your signal/reception.

the search button bug is connected to 3g connection.... it presses itself like crazy....although when wifi is on the problem is non existent. Its a common problem and is known to be fixed by a new radio

[Q] Issue with 1.47.401.4 : often get "Limited Service" and hard to get signal back

[Q] Issue with 1.47.401.4 : often get "Limited Service" and hard to get signal back
Hi there,
Since 1.47.401.4 (and never before with 1.28.x), I'm experiencing issues with the radio, especially voice:
1/ I often get a "Limited Service" warning in places where I could easily get a decent signal to give a call.
2/ Each time I got the "Limited Service" warning, it can take ages before the signal gets back (after I moved to some other place).
3/ Sometimes, I need to reboot the terminal to get the voice signal back.
I did perform a full wipe (factory reset) on my phone and install the rom again (using the roms.zip method within the bootloader) but it didn't really solve this issue.
I also cleaned the sim card contacts, just in case, but this was useless.
I also chose "GSM auto (PRL)" in the phone settings, this helped a bit, but still this annoying issue remains.
If someone got a clue, I'm interested ! And if anyone is experiencing such weak/bad signal issue, I'm interested in your feedback.
Cheers.

I have the same problem! 1.28.x was OK, bet the newest one in terms of receiving signals is just terrible!
Hi, have you found any solution so far ?
HTC wants me to sent my phone back but I don't think this issue has something to do with the hardware...

In complete contrast to what you two are saying..(see my old thread where I had this problem with the older radios http://forum.xda-developers.com/showthread.php?t=1133785)
I'm now running on the latest radio but not the latest ROM (as I use LBC MOD which is currently based on a 1.36 ROM) and I no longer experience this problem.
My conclusion being that the newest Radio is better.
Thanks for your feedback.
Would you then say that the "Radio_20.28I.30.085 AU_3805.06.02.03_M" was the answer to your phone bad signal issues ? Then, I might need to use another rom an check if that helps...

I have this problem as well and have emailed HTC but received no reply yet.
Also sometimes it all looks okay and allows calls out but incoming calls go straight to voicemail.
Well, HTC will probable ask you to send your phone for repair.
Actually, this is what they've just replied to my email. But I won't send my phone for a simple flash that I could do my-self !
It seems this is a known issue of the HTC phones (there are plenty of such reports on the internet).
Although this problem hasn't effected my calls on the latest radio version, I do agree that I've often seen what looks like severe signal fluctuations, from zero bars to full bars etc, I've also read about this being an issue on the incredible s
I'm hoping that further rom and radio upgrades will improve this.
Sent from my HTC Desire S using XDA Premium App
It seems that the "Limited Service" issue is caused by a signal loss (i.e. using the elevator for instance) that is never followed by an automatic "good signal" retrieval (i.e. after leaving the elevator and going to a place where signal is usually very good).

I'm afraid that I don't understand what this question? could you PM me?
did it mean did I switch my phone to WCMDA only? if so the answer is NO, mine is set to Auto as around where I live and work there is reasonably good signal.

Have you progressed any?
I tried flashing to 1.28 via the RUU at http://forum.xda-developers.com/showthread.php?t=1002506 but it doesn't appear to want to do a downgrade.
I don't seem to get getting the no service at the moment but I am having problems with incoming calls going to voicemail when the phone claims to be connected.
I put my SIM (giffgaff, a MVNO on O2-UK) into my old phone (an XDA Zest) and put an O2-UK SIM into the HTC. At times I could call the XDA with no problem but calling the HTC went to voicemail - two phones next to each other on the same network....
Of course I can't say if this was a problem with 1.28 as I wasn't looking for it but I suspect 1.47 is the problem.
As expected HTC want me to send the phone back which I think I might do and try and persuade them to downgrade it for me.
yes some progress, at last ! I followed the step by step procedure to s-off the rom 1.47.401.4 rom (http://forum.xda-developers.com/showthread.php?t=1194488) and then downgrade to the 1.28.401.7 rom that I was using originally. And now everything works fine...
i could say that once again i learnt that newer doesn't mean better

What method did you use to do the downgrade?
I was thinking of trying the method here http://forum.xda-developers.com/showthread.php?t=1190992 which I don't think needs s-off.
Update: I tried the non S-OFF method and have downgraded to 1.28 - I'll see how it behaves now.
I used the PG88IMG.zip method. Basically, you need to copy the roms.zip extracted from the RUU installer to the root of your /sdcard and then reboot your phone to the bootloader.

I ran the RUU exe directly which seemed less involved. It's looking good so far but I'll need to get out and about and see how it behaves in different locations.

Nexus S with broken (?) 3G/GSM

Hi,
I'm having trouble with my Nexus S, and it might have started after installing Jelly Bean (though probably not). The phone is somtimes unable to connect to 3G, and sometimes unable to call/receive calls. More often not working than working, both of them. I tried factory resetting and I also tried my SIM card in another phone (and another SIM card in my phone), with the same result. Something must be wrong with my phone, the only question is if it is a software error or hardware error.
Anyone have any tips? Perhaps how to check if the radio hardware is working (some app perhaps?)? Any ideas on what else I might try? The phone has been working perfectly for more than a year, so it's really odd it suddenly has problems. Anyone had similar problems?
Thanks in advance!
1. Are your NS is rooted...??
2. did you try another JB Custom Rom..???
or
3. is it still working good when you downgrade to ICS or other ICS Custom ROM...???
Then, if thats way still have same result, its might be hardware problem.

I rooted it yesterday to be able to try custom roms (tried Cyanogenmod 9). Same problem. I then returned it to stock, which made it reflash everything, and still the same problem. I'm starting to believe it's a hardware error. Are there any diagnostic tools available to check the radio module?
Thanks for answering!

Well, just try a radio that's for your model, search for nexus s radios in xda you should be able to find a thread which has all The radios, and choose appropriately.

Maybe you have to get the correct access point name from your provider. If I do a clean flash I have to input it by hand as otherwise I cannot connect as well.

[Q] Radio Issues

Alrighty, I have a One S S4, rooted, running ViperOneS 1.2.1.
Not the first time I've run a custom on here, I've been bouncing back and forth between Viper and Cyanogen, usually without issue. Normally, I've been using CWM recovery...
My problem is that I can't get a new radio to install. I've reinstalled Viper a few times, full wipe and all, reinstalled CWM, and finally, just tried using TWRP. CWM says that it updated, but nothing changes, TWRP just gets stuck saying that it is updating, but never does (have to force a shutdown)
So...anybody else run into this problem? I can't find an answer anywhere, and I have no idea what to do next, because I want to keep Viper on here, but right now, my mobile is alright, but I get no WiFi (and the solution that I'm being told is to install a new radio (would that even fix a WiFi issue))
Please help...

It's probably the hboot you have on your phone not letting you flash the radio ? As for Wi-Fi you probably need to just flash the Wi-Fi partitions. You need to find out what hboot you're on as well as if you don't know how to check which radio you're on you should look into that. About phone software baseband and more something like that.

As far as radio, it's 1.08ts.50.02.16_10.08e etc
As far as hboot version....nothing has changed since the time I could reprogram my radio
I'm pretty versed with the phone, I'm asking here, because you will know more than I do...but I know my some of my phone, and I definitely know how to program...but I don't experiment as much as I want to, and I want to know how to fix my phone..
sorry, little drunk at this time, don't want to sound like an ass...
If I think that I'm missing a basic step, I'll ask =)
The hboot, as far add I've know hasn't changed, but I don't know what does. Old versions of recovery, no luck. Had programming issues, get stuck in booloops etc, make it work right...n dint know why the radio won't program out of nowhere =(

[Q] Nexus 5 Massive Network Issues - Common?

Hi all, I aren't a new user but have attached my Google account on this log in so....meh.
I understand that from update 4.4.3 and upwards many N5 users experience loss of their mobile network where switching to aeroplane mode then back again is the only way to rectify this? I was fine until I recently swapped to Virgin (UK) which uses the EE network, ever since this my calls go straight to voicemail unless I manually select the provider myself.
I was having a whale of a time with CM11 and only found out this issue after tearing my hair out for a couple of weeks but it is something I cannot have because I need my phone to be available *always* due to issues with my mum. So what I have now done is backdated my system to 4.4.2 which seems to have worked *but* I now get the system update notifications which I have dealt with but I now seem to have messed up the Play Store
Is there any one solution for this problem where I can have everything actually working as it should? 4.4.2 stock seems to run a lot better and seems a lot quicker in all honesty, quicker than even CM11 than is the gods honest truth.
Please help I dearly love this phone and need it to work for personal reasons and I aren't in a position to buy another right now (quit joib to look after mum etc) have I tugged at your heart strings enough yet?
Flash 4.4.4 but flash the 4.4.2 radio then?
On my carrier in Australia, I've never had a single drop issue, on all versions of the radio.
I live in Ohio and my connection is awesome with ATT. The only problem I have with network is my house and church. Lol Everywhere else like work is awesome. I think the network you choose is the major player in this. The phone itself is great on network.

To 100 % prove it to myself I did the stock system updates, first to 4.4.3 then to 4.4.4 straight after I rang myself from a landline and it went immediately to voicemail. I then tried to install Cyanfox and that fails on the set up wizard as did liquid
linaro, both using the correct gapps and several versions.
So my next try is an older CM M3 iirc because I think doing the radio thing is a bit beyond my skills Lethargy

Strange unknown wakelock (ProxyController, phone process) since 5.1 upgrade.

My Nexus 5 which I upgraded from a 5.01 to the 5.1 (stock Google rom, without wipe) has a very big battery problem: the device never reaches deep sleep.
I have some years experience in identifying wakelocks, but this wakelock is new. And the strange thing is: I can't even find a thing on Google. Nothing!
The wakelock is a kernelwakelock (PowerManagerService.Wakelocks). I investigated at partial wakelocks which wakelock it is. It's a wakelock called 'ProxyController'. It's related to the phone process/app.
I wiped cache, tried different Kernel (elementalx). Changed CPU gov, wiped dalvik, changed network, refreshed some settings. Disabled unused apps. I even reinstalled the image and other files through recovery. But nothing helps.
Also I noticed, it might be related, that sometimes my phone reboots or it looses sim and signal. (Which worked perfect in 5.01!). All problems started after 5.1 upgrade.
Ofcourse I can do a full wipe, or revert back or try a custom rom. But I hope it is possible to fix, because besides these weird problems it was / is perfect!
Edit: Important, I couldn't be called either. Also calling someone was difficult and the phone process kept freezing. My phone (and then the phone part) was totally broken! Radio of 5.01 did fix. Read comments below!

I tried a clean flash now. I didn't only have a wakelock but nobody could call me either.
Also sometimes the phone process did get frozen.
Now I tried a wipe and totally clean install with other installer (The Google original images and installer!). I did not install any other new unneeded apps. And I still have the problem.
I think I will try an older radio now. Very strange... My phone became unusable after the upgrade from 5.01 to 5.1. This looks to be some major bug.

If it happens with a completely clean flash with nothing installed, and with every radio version, then it could be a hardware problem.
But yeah, try an older radio version.

Yes I fear that too.
However, it started immediately after the 5.1 upgrade, before all was good...
It also seems there might be a link with screenoff/standby. When it's in standby and I switch the device on I see it has no connection or is reconnecting. As if something goes wrong with the connection then. Maybe important information.
I will investigate further. Ofcourse all new tips, ideas and infos are welcome. I will also keep you updated.
Update:
Flashed 5.01 radio into my 5.1. Now it SEEMS to be fixed. Phone goes to deep sleep, I can call people without crashing and I can be called. For now. But don't cheer to early, I have only tested for 10 minutes.
So it seems to be something completely wrong in this radio in combination with my device or simcard or provider. I am using Vodafone NL.
Update: a few days later. Running 5.1 rom with 5.01 radio and all seems ok and fixed!

Hello. I am running this Radio (2.0.50.2.22) since my last post, A couple of days. I am experiencing no problems as far as I can tell. It seems to work well and the big problems seem to be gone.
I can advise you to flash this Radio from the 5.01 packages. Big chance your problems will be fixed.
Strange that there is only one other person for now. I am thinking what we could have in common. What is your provider?

Hi,
Thank you for your quick answer. I'll try it first thing in the morning.
It is weird indeed.. My provider is the equivalent of Orange. As with you, it only started to happen after the update to 5.1.
I'll report back. Thanks!
