[Q] Nexus One reboot when using 3g

hello guys I have a nexus with one gingerbread 2.3.4 and when I use the 3G network after 2-3 minutes the phone restarts. with this bug I can not use Internet
any ideas? Thanks!

Yes. Me to.

What ROM and/or kernel combo you guys using?

I have the stock rom ota gingerbread 2.3.4, nothing changed, full stock. I recently tried miui 1.5.20 the problem is the same. may be a hardware problem?

Does the phone get hot to the touch on the back? Does the phone still reboot if you turn off 3g data and you go exclusivly Wifi?
Had the same issue with my old Nexus 1. Called HTC support and they immediately said it was a defective board. RMA'd and got refurb, but at least it does not reboot when I use 3g.
Good luck.

thanks jhsiao36, think if I update the radio version 5.12.00.08 can change something or brought it in for service?

I didn't help for me. I tried the 5.12.00.08 radio and it suffered from the same 3g reboots. But when I disabled 3g and used Wifi, never suffered from reboots.
If the phone is still under warranty, definitely encourage you to call them. HTC's customer and tech support is the best I've ever seen. They replaced it no questions asked, even though my phone is rooted and bootloader unlocked.

+1 They are awesome to deal with. It really makes me sad that they are starting to lock down their phones, because I won't buy a phone if I can't run custom ROMs on it.
But with the radio, I highly doubt flashing to 5.12 would help. Google released the 5.08 radio with the OTA update to Gingerbread. If 5.12 was any better, I'm sure they would've included it. There had to have been a reason they stuck with 5.08.
If you aren't afraid of losing anything, or already made backups, you could try the passimg method of giving you a completely stock install. See if the problem occurs with that as well. This would rule out software vs hardware.

No one can really solve it?

I really don't think it can be resolve without sending it back to HTC for a replace/repair. As I said in my previous posts, I've tried 3 different ROMs - stock, cyanogenmod 6 and 7 - all exhibit the same issue - reboot when on 3g, but perfect if on Wifi. And yes, it will reboot even on a freshly install ROM (no apps installed).
HTC knows of this issue and they will replace/repair. I got a refurb and it works perfectly - stock, cyanogenmod 6 or 7.
Sorry, probably not the answer you wanted to hear, but search on <insert your favorite search engine> and you will find that this is a fairly widespread problem.

Thank you for your answer! It does not work, had sent a factory repair.

After several tests, on Monday I sent the phone in for service. I think it's a hardware problem, maybe a bad batch of motherboards.
my S / N: HT05... and your?
I will tell you just back from assistance.

Did you ever overheat it? I believe that the N1 has a problem if you really push it that it can overheat. Once it happens once it will happen again and every time it takes less and less to cause the reboot. Eventually it reboots just with 3G.
I was running mine in the car-mount with GPS, Google Maps (3G), screen on brightest, on a hot summer day while charging ... and it rebooted. Didn't think much of it but then it started rebooting every time I used GPS and charging.
In the end it was pretty near useless ... rebooting all the time. I sent it in twice (the first time they couldn't reproduce the problem) and the second time they replaced the board. Problem solved.
Now I am very careful not to overheat it.

Can I change the radio on a CFW?

Hi all,
I am fairly new to modding and would like to ask a quick question that may be simple for some of you.
I have a MT4G "Glacier" and I did some steps found on this forum to root and install a custom firmware on my phone. For the past two weeks, I must have installed about 28 ROMS. Yeah, I know... I have too much free time.
Here is the issue. I have not found a single rom that can do it all. With some roms, my 4G speed don't work. With others, my screen flickers too. The last one I installed, doesn't have sense. No matter what I do, I can't get a rom where my 4G speed works, which I can't live without since I use my phone as hotspot all the time.
The rom that I like the most was [ROM] [ICS] Glacier_One_V_1.3 (9/24/2012) because it has BEATS audio, is based on ICS and it has sense 4.0 which looks and works great. I would love to find one that has all the bells and whistles like this one, but where I can still use my 4G speeds and my screen is not flashing all the time.
I understand that the RADIO is what controls the WIFI, cell signal, etc. Can I update the radio, for one that currently works under Gingerbread into this rom without messing anything up?
If so, how will I go about it and what things do I need to get? Please keep in mind that I already flashed back to stock and I am very comfortable with flashing now, but I don't know much about what goes inside the ROM itself.
Any help will be greatly appreciated.
Thanks,
Manny

Let me jump in before Jack shreds you for ignorance. The radio IS NOT part of your ROM and has nothing to do with your wifi, gps, the space station or anything other than cell reception (as much as software can). Changing it can be beneficial, but is also dangerous. A failed install means a permanently broken phone. Explain what you mean about not getting 4G.

Appreciate you saving my skin there. Sorry for my ignorance.
What I meam by no 4g speed is, my signal bar on the top right of the phone, almost always reads 4g and get fast browsing speeds on my phone. I can tether my internet to my laptop and it runs great on my stock Ginger.
The moment I go to custom ROM, I can only get 3g and is not just display issues, because the speed is slow based on speedtest.net.
Makes sense now?

Hmm, well, I'm not aware of speed issues on ICS, at least not anymore. However, if you're having issues with it you might try a Gingerbread ROM like Android Revolution HD or Insert Coin.
If you plan on sticking with ICS, you might try the "3G Hacks" in Pimp my ROM. 3G and 4G run off the exact same radio, but a value or two in the ROM may, I repeat MAY, affect the speed. What kind of speed differences are you seeing? Are you comparing these at a similar time of day?
Also, holy crap. You said CFW. I haven't seen that term since my old PSP hacking days. Good times.
Sent from my myTouch 4g using xda app-developers app

I am comparing at relatively the same timed, days and locations. Office versus home, etc.
I will flash againg ICS and test your recommendations. Thanks for your help.

Compare 10 runs back-to-back, same time, same day, same place. That would be a good basis to discuss something.
For all the rest: no ICS ROM will work properly for you. If you want stability - drop to Gingerbread.
About the radio - estallings15 already answered you. You're looking in the wrong places.
"4G" mark on the signal bar means ABSOLUTELY NOTHING on this phone. 4G means something where "4G" stands for "LTE", which is a different set of bands and different transceivers. This phone doesn't have LTE, nor does T-Mobile AFAIK. So it's just an icon. But - make sure you have "H" showing instead on custom ROMs (HSDPA mode). It should show up when the phone starts actively using data.

This makes perfect sense. I really appreciate your prompt response and suggestions.
Back to flashing.

Why am I getting no service when I'm out in the street?

I suspect it's the radio. I keep getting crappy signal apparently with the Panache stock recently. It's taken to a new level now with no service out in the middle of the street. Is there anything I can do than try to switch radios? Even right now, I keep getting switched from 3G to HSPA+.

Radio controls all network communication. Just be careful when changing it. Make sure you verify the md5.

It varies by location. I'd start with the latest GB radio and work backward.

Radio Issue
I have a MT4G running 4.2.2 on LiquidSmooth and I cant get anything over 3g even in areas where I previously had awesome 4g service (on stock 2.3.4). I checked my md5 and it does not match any other radio/baseband's md5. I'd really like my 4g back but I also don't want to brick my phone. Currently my md5 is showing up as 60de66c8b88d27b9a3bbae385b7f71dc and have yet to find one anywhere to match it. I am fairly new to rooting androids ( I had an iPhone for like 5 years and I just got fed up with the limitations even when it was jailbroken) I read a forum about extracting the radio.img from a stock rom but I was still iffy about the md5 not matching. Absolutely any advice would be great. Thanks in advance (and apologies in advance if I somehow posted this in the wrong place or something)

:sigh:
"4G" and 3G use the same hardware. None, I repeat, NONE of the available radios break "4G." What you're seeing is a difference in the icons used. Whereas the stock GB ROM simply shows "4G" when using HSPA+, the AOSP variants show 3G when idle and switch to H/H+ when data is being used. There is nothing you need to change. It's a gimmick that often evokes a placebo effect.

Thanks for the quick reply and thank you again for clarifying that. But when I ran speed test my download speed is showing around 350kb/s when I usually get around 1.5 mb/s. I recently asked my friends in the area that also have t mobile and they said they've experienced a decent loss in speed/signal just in the past month or so. So is it possible that another baseband might increase my signal strength at least? Because if it's not possible/effective than I feel like I'd be wasting time trying to fix my md5 issue.

If you're worried about the radio, download a different one, verify the md5 ON THAT DOWNLOAD and flash it. Feel free to report the speed difference, if there is one.

4G not working after flash on US T-Mobile network

Hey you all! I've been looking at threads in the last couple of days but I cannot find and answer to my question. I'm sure someone here has addressed it but I need a little help. I have a MyTough 4G and I have used at least 5 different ROMs with it but since I nuked my stock ROM, I haven't connected at 4G in the T-Mo network. What am I missing?

Does your signal bar say H? If so, you have 4G.

Did you checked apn settings!?

Most of the ROMs I've used do not say 4G. Like estallings15 said, if it says H, that means you're on 4G.

Well I can say I used to have a similar problem unless I was on a version of cm. Not sure if this fixed it but I went back to stock unrooted for unrelated reasons and then ended up rooting again and have noticed that I haven't seen the problem arise again.
But the ROMs do stay on 3g until the "4g" speeds are needed

Unlocked with GSM + LTE!

Hi everyone, I use an unlocked Sprint Note 4 with Cricket/at&t. I understood that by unlocking that I would only ever achieve HSPA+ speeds because Sprint locks the LTE band's available. I accepted that, as it didn't bother me and I mainly use Wifi, but that didn't stop me from trying.
All my attempts never seemed to make a difference, until the other week, I finally realized that LTE must not be available at my home. Because while I was driving I noticed I had a LTE signal, which was a complete shock to me. So I did some testing and I only received HSPA at home with all my phones.
Conclusion:
So that means one of the steps I did must have activated LTE. I do have to force it to connect sometimes with phone info shortcut. Or at&t is broadcasting on one of sprints bands in that area.
If anyone is interested in this, I do believe I know the exact steps to replicate this. If this shows interest, I will turn this post into a guide. This would be my first guide, so bear with me.
Edit: After further testing, I'm concluding that I'm only getting Lte in certain area, so it must be that at&t is using one of the Sprint bands there. If something changes, I'll update!
Edit 12/11/16 - only getting lte at certain place. It's band 2. Added pic below.
Pics below show Lte. You can see from crickets website that 4g is only 4mbps and Lte is 8mbps.

I would be more than interested in knowing how you unlocked the LTE Bands because (you must be aware through my previous posts) I too use unlocked N910P with a GSM SIM but all I get is H+.
I did try to unlock the LTE bands using a thread on XDA but it did not work as the tool wasn't even able to recognize the phone.
Hence, a step-by-step guide would be appreciated regarding the same.

I'm not sure if I unlocked them or not.
This just all became aware to me that i have lte. So I'm still testing. It seems like I'm only getting lte in one certain area. I don't know if maybe at&t is using a sprint band in that area. And that's what is making it possible.
I also don't know if anyone one thing i did made this possible. I will edit my post with all my changes. And you can test to see if it changes anything for you. Give me a bit.

I'm also on a domestic unlocked 910p with cricket, and have noticed LTE popping up from time to time. It's not consistent though. I just assumed it was because I hadn't changed my network mode to GSM/UTMS. I was driving at the time so I couldn't check to see if it was actually working.

I've been testing cm 14. So I just now went back to custom stock. When I go back to work today in gonna do more testing. But after seeing your experience and my assumption, I'm thinking that I don't have any more lte bands. But just that att is using one of the bands this phone has.
I'll keep you all posted.

Im also interested, I'm using AT&T towers as well through straight talk... but ive only ever been able to get 3g. But more so than not lately, unfortunately, ive been getting stuck with GSM service, not even 3g.. So if you figure something out that'd b great , otherwise any tips to improve my speed capabilities would b much appreciated. . And just 2-3 miles away is an AT&T tower so i should be capable of much more.

Here's the pic. I'm on band 2 here in western pa. Don't know how yet. Don't travel to much to compare. But this is only place I get Lte. So I'm still trying to figure out what and how I did.

Click to collapse
I'm just gonna list some of the newer ones that are still being developed. But there are also more stable builds out there but they're no longer being improved upon. = final build. (Ex. Any of @tx_dbs_tx older roms are very stable= MOAR rom, Note 5 rom, Mr Wonderful)
Back to current ones,
If you want a very customizable rom then Dtux Rom here is great. I use it myself when I'm not testing another. Plus Dev is getting ready to put out v7 very soon.
Then there's new CM14 here. Still getting all the bugs out but is very stable enough for daily driver. If you want Nouget then it's only option right now. Or if you want a minimal aosp rom, then it's the way to go.
Then a lot of people like trying the Note 7 ports, specifically one of these here. But it requires some work to get service working. Personally I'd wait til @tx_dbs_tx releases his Note 7 port. Won't be long, i hope. But it'll be tailored for our device.
There you go, that's my personal opinion through experience. It just depends on what you looking for. But all of them are stable. Good luck!
Edit. I just re-read your question. If your looking for a stockish rom. I'd suggest Mr Wonderful here! http://forum.xda-developers.com/note-4-sprint/development/rom-t3396498
Read next post!
Or you can try Dtux but just don't install the modset, if you don't want all the custom stuff.

Sprint Note 7 port is very close to a public beta release! Keep looking in the Sprint N4 development forum ETA should be before Xmas. Expect only minor bugs such as fingerprint scanner and always on display. otherwise completely functioning and pure Sprint N7 rom. I will move on to the next available Samsung Nougat rom if I have the time and patience and if I haven't upgraded my phone by then. Otherwise this N7 port will be my last rom for the Sprint N4.
