To give a back story on what I'm trying to accomplish, I'll explain my situation.
I work for Bell, in a retail store, the main reason I came to these forums was to find a way to re-flash phones in store to avoid having to doa what little stock we have of the phones. One of my colleagues from another location told me about the new update from Kies locking phones up at a ridiculous rate of 25%, so I'm trying to be pro-active about it.
Once I got in, I got a bit carried away with 2.2 software and what not. Now, i'm no expert, but I'm computer literate and made sense of most of the process, some extra guidance would be nice though.
Playing with the phones we have in store, I was able to flash every available software I could find on said phones, however a constant issue is found. I can not get a solid data connection. If I disable data, everything works fine, soon as I turn it back on, nothing happens.
Furthermore, I followed a thread regarding re-flashing everything back to Bell's stock settings and it didn't help me along at all.
I have done some searches, but i'm coming up dry. I know you've probably heard this hundreds of times and I'm sorry for being new to the process, some guidance towards this all would be great.

Can you elaborate more on this?
what do you mean by unable to get a solid data connection?
what kind of data connection are you referring to?
USB cable between phone to PC?
or Wifi data
or APN (3G) data?

not sure where you got that number from, but it's not that accurate
the reason for the ridiculous high amount of returned phones is due the Internal SD card problem that was found.
even under normal conditions if it gets formatted a lot or used a lot it seems to die faster than its Europe counterpart.
apparently on the Canadian version of the I9000 they use a bad batch of Flash Disk for the storage memory
there is a sticky Topic Poll about it.
it is NOT the ROM flash from Kies that are killing the units, just anything software that constantly access the internal SD can produce the same effect.

the rest of the returns you guys at Bell are seeing are due this other problem discussed here http://forum.xda-developers.com/showthread.php?t=775017
it can be reproduced, but you need the ideal conditions to do it.
it has to do with signal quality and tower availability

I'm referring to 3G connection. I have set up the APN, even tried different settings, all producing the same results.
In regards to your second reply, the phones I've seen at this location for DOA's have mostly because of a failure to fully turn on, the display won't show. I've experienced similar issues when a flash doesn't work properly, a re-flash fixes it. We started seeing this issue after samsung released the update. However, I'm not going to flash a customers phone to have them lose 3G connectivity, or open up other issues.
Basically, I'm looking for two things. Primarily a way to re-flash everything to work as if it were out of box, with the latest software update. Secondly, to be able to get a stable 3G connection on 2.2, everything else seems to work fine at this point.
i'm not even going to touch the 2.2 topic as it's not even released officially.
the current stable official flash is JH2, on JH2 3G should work properly (stable), another thing you can do is to go into the service menu using the secret codes (wiki) and make sure the proper 3G bands are selected for WCDMA
1900 and 850 should both have a start next to it
next check is the *#0011* to see if the towers keeps constantly changing
that's another reason for unstable 3G if the phone keeps jumping towers every few seconds
this is also related to the 2nd link i mentioned about people getting Comatose Syndrome on the phones, which locks up the phone, and they have to reset the phone to get the phone to work again.
I'm running JH2 currently, I ran *#2263# 850 and 1900 are available. Also, ran *#0011# both are available, ran a test on youtube it worked for 5 minutes.
Any ideas?
**Edit**
I lied, on the *#0011# it only shows 1900.

Get something straight
the update samsung released was JH2, and it is not causing the problems you've seen.
the problems with the symptoms described are after they were flashed by the Alpha & Beta versions of Froyos 2.2, which many of them do end up losing the 850 band, the band issue can be fixed with much work.
there have been at least 4 different leaks of froyo, each one bringing its own volume of chaos and bugs, the most dangerous 2 are JPH and JPK, one loses the IMEI / ESN number ID, the other one kills the internal SD

Since the I9000M and I9000 are hardware based bands, you should always have the 850 and 1900 bands for 3G
Many who have tried Froyo and back had come across the problem of losing the 850 band, mainly because the Froyo leaks were intended for the Korea test team running international I9000 devices
some times just by flashing the Firmware back to stock or Froyo betas doesn't actually activates the 850 band, even though it shows as selected in the Service Menue
if you go back to the Band Selection screen of the Service Menue, you should choose bands that are knowingly not available in canada, like say band 900 for example, and then go back again to the service menu, and band selection to only choose 850
once you can confirm 850 works, then you can select 1900 as well, and now both of the bands should be active permanently until some body else screws it up again.
using *#0011# and trying to call the voice mail are the fastest way to verify for line and for 3G on 850
you can also try the app speedtest from speedtest.net

Hello I seem to have a problem and I am hoping someone can help. My phone is rooted running Modaco r20 Desire Rom. Radio is ERE27. I have a strong 3G signal in my town with T-mobile. My problem is that for some reason whenever I use data (internet,online gaming, searching using apps etc) the icon will stay on 3G then switch over to H. Sometimes it will stay on 3G and it will not allow any data. I know about the EDGE to 3G issues. I don't seen to have that issue. Can anyone help and or know why this happens?
Usually, when browsing the internet or anything is being downloaded at all - the 3G icon will switch to H. Really only in custom ROMs though, I don't really believe this happens in the stock ROM.. it's not a bad thing or a problem, at least not for me.
Data doesn't completely shut off for me though.
The "H" means you are achieving an HSDPA connnection of sorts. Stock does not have this icon in it, since HSDPA is a form of 3G and they didn't want people getting confused by it switching from 3G icon to H icon.
HSDPA is faster than basic UMTS, aka "3G"... so it is not a bad thing at all.
No idea why you loose your data connection all together when it switches, since it isn't doing anything other than recognizing you have a faster data connection than basic 3G, nothing is actually changing to cause you to lose your connection since it is still the same connection.

no it is not...
mine does the same thing... i have to twiddle my thumbs and wait when it switches between UMTS and HSDPA... they are different frequencies just like EDGE is on a different frequency...
I don't think UMTS and HSPA are on different frequencies, the same two frequencies are used (alternating for downlink/uplink) for both, those are 1700mhz and 2100mhz.
For some reason I don't have this problem on Long Island, but when I'm in the city this happens the whole time. Might be something to do with the way the network is configured. Basically whenever data is in use, it just says 3G, but as soon as I browse to a site or actually use data, it switches to H within a second or so. I think a stock ROM would technically be doing the same thing, but it just won't show the actual switch, as it doesn't differentiate between HSPA and UMTS in the top 'taskbar.' Although it would probably show this in the phone status screen under settings.

The "3G" to "H" (and back) is a "red herring". If it's "stuck" on 3G when you're trying to do data, it means your handset is having issues communicating in the AWS bands for 3G (2100/1700) and the handset hasn't dropped back to GSM/GPRS/EDGE (1900) yet or is attempting to switch frequencies and the associated towers aren't cooperating with the hand-off or the hand-off is failing.
Cheers,

I'm in times square. My phone has never switch to UMTS. Either HSPA or EDGE.
also while it's idle it will only use 3G
it will switch to H to transfer data, then revert to 3G

Not that I've found. I have this problem BAD here in Phoenix. I never even bothered with WiFi until I got a Nexus, now I can't live without it. I found that sometimes kicking the phone in and out of Airplane Mode sometimes alleviates it being "stuck".

Which Modaco ROM? If it is Desire, you have to flash the newest radio, and do it after flashing the ROM itself, otherwise you will have major Radio issues... at least that is my, and a fair number of other's, experience.

Yeah its Desire rom. I have radio ERE27 right now
Try upgrading to the newest one, 32.26.00.24U_4.04.00.03_2:
http://android.modaco.com/content/g...-online-kitchen-optional-root-insecure-himem/
Make sure you have at least 50% battery before flashing, just download and flash via recovery just like a ROM, do not panic, ever, during the process and do a battery pull, just wait for it to flash, then ask you to reboot, reboot, it will then do the actual radio flashing (you will see a box with arrow screen for a couple minutes) it will reboot on its own into recovery, say "writting" cache with a progress bar for a few seconds. The bar will go away, but the "writting cache" text will not, don't worry it is done, just reboot and then double check it flashed by going to about phone, software, and checking baseband version.
Just remember, can't stress this enough, do not pull your battery at all during this process. And make sure you have at least 50% battery before starting. Flashing a radio is the only way you can brick an N1 right now, and only if you pull the battery during the process, or have a bad download. Speaking of which, I do recommend checking the MD5 sum to make sure it is a good clean download.

Same thing happens with me. I'm in Phoenix myself with T-Mobile and running Cyan 5.0.5.3 with EPE54B and baseband v 32.26.00.24U_4.04.00.03_2.
I'll have full bars for 3G and when I goto check the market or anything internet related, the 3G will switch to H and work or stay at 3G and pause with connection error, retry or cancel.
I started having this issue after updating my factory stock radio. Anybody know which one is the stock/default radio IMG is? I'm thinking of downgrading and seeing what happens.

Any solution?
Only GPRS/EDGE does work, if 3G is available, it disconnects automatically until 3G isn't available.
Solution: Set to 2G-Only :-(
Anyone has the same problem?
I didn't have this problem with FRF 72.

Have you tried going into your phone settings from *#*#4636#*#* and setting it to wcdma only? I did that on mine not too long ago and no more dropping to edge for me!

does it lose complete signal? or does it show 3g still but just not doing anything?
Mine was working at first after flash. Then at about 2am it just kept trying to load then times out. Still shows 3g but just dont do anything. Im hoping its just tmobile messing with their towers... I dont see why it would work at first then not now..
The problem is, that i can only have a internet connection, when the phone is logged in into a gsm or edge network.
as soon as wcdma is available, the phone disconnects from the internet.
the signal is always available, but it looses the internet connection when it changes to 3G mode.
when the phone changes from 2G->3G mode, i see for 1s the 3G icon and then no icon will bi there.
when it changes back from 3G->2G, the EDGE/GPRS icon is visible again.

ok thanks for clarification. My problem is different. I think related to phone company.. I still show the 3g signal and even have bars, but the pages dont load and eventually gives me the check your service and try again alert....
So Im hoping soon its working again for me... And I hope you as well figure it out.....
Thank you Good luck!
Had the same issue after update, did *#*#4636#*#* and noticed I was set to GSM only. Set it to WCDMA preferred and now it's good.
Thank you very much, thats the solution!!

Thank you. Updated to FRF83 this morning and I've had a full 3g signal, just couldn't pull data all day. Could over edge. Sure enough, GSM only was selected.
AT&T N1.
I'm having the same issue on a non-rooted phone on T-Mobile. No 3G after the FRF83 update. Full bars of service and 3G displayed in the status bar. Dropping to Edge only works but there is no data with 3G.

Switching to WCDMA preferred doesn't work for me though.....any help is welcome
I think it's a hardware problem with a lot of N1's.
Mine was ok the first 2 months, and later, 3g not working. This is driving me crazy ):
I have tried everything. Change the simcard, I did a reset of the data with my telcon, and nothing happens.
I've seen these problems on many N1's.
I hope google / htc release a fix for this problem.

how bout checking your bands in the service menu. so *#*#4636#*#* -> phone info -> press the menu key for more options -> select bands -> choose one appropriate for your region (ie "USA BANDS").
If all else fails do a factory reset by going to the settings -> privacy -> restore factory defaults.. of course do a backup/sync/whatever before just to make sure you can get all your apps back.
There's other ways to do a factory reset via the bootloader .. its under recovery and you press up volume or the trackball I think and you can just select all the clear/erase settings there and that should clear out everything on the phone's internal storage.
The factory reset worked for me (via bootloader) when I upped from update-1 to FRF50 and didn't have any data icon next to my signal strength. Could call out but couldn't get data.
Hope that helps.

Check your APN settings. Do a full factory reset from the bootloader. If nothing works you should call tech support again. Most 3g issues where you have issues with connecting are service/signal level related. I *****ed early about my 3g issues on tmobile and it was the network as they've pretty much gone away with improving the backhaul in my area for HSDPA+ or updates to the phone's radio.
HTC is really really really cool about swapping phones and repairing them. If you feel you have a nexus that has hardware issues call them. I did this 3 times already (one time for minor cosmetic issues with the refurb they sent) and I couldn't be happier about how willing they were to replace/repair the phone. It turns out I really didn't have any issues with them at all.. with any issues with hardware from the second refurbished phone. It was service or software related and I'm happy to say with updates/tmobile service improvements I couldn't be happier with this phone.

Thanks blisk, but the thing I don't understand is why Blackberry 9700 with T-Mobile bands, doesn't have problems at all ?
By the way, I rooted my phone , so the thing with the warranty it's complicated
I had it happen last night at work all night, but when i got home i checked my wife's tp2 and it also was doing the same thing so for levity wasn't the phone but tmobile. They started worming the same time also.... I think its tmobile.
Hello, I had the same problem with my imported n1. I'm using the tmobile version non rooted fully stock manually updated to frf83. I did a *#*#4636#*#* and selected wcdma only, rebooted and couldn't connect to my gsm network. Went in again and did a wcdma preferred, rebooted, and I works better, still changes fast to edge and G, but less often, I'm still trying it but I have high hopes its gonna be ok
Mmmm i did have problems with 3G too after pushing FRF83, but i found out that for some reason the APN settings weren't set correctly after the update. In my case the port setting after the proxy of the APN wasn't set, i changed to the correct value and it worked.
In conclusion, check your APN settings.
Just went from FRF72 to FRF83 and it's working fine.
I'm currently set to GSM auto (PRL) in the *#*#4636#*#* and I didn't change it to that after putting on FRF83.
Ok, so I know it's not the csc, or the rom, or the apn settings, or the modem, or the band selection. It's not an app, or even a signal issue. It's not the service or network selection. Wiping didn't help nor did a factory reset. Every time my phone connects to an edge network, it won't connect to an hsdpa network without me going into settings, wireless and network, mobile networks, wcdma only and then back to gsm and wcdma. Any suggestions?
Anyone that comes up with a half-way decent suggestion gets a Thank You....
I'm guessing that no one has come across this before? It's not like it won't connect to HSDPA, it's just that it won't connect automatically. Believe me when I say, I've searched samsunggalaxysforum, google, and xda for a solution so I don't think this is a problem that has been posted here as of yet. Forgive me if it is and lead me to it....
Bump.
I don't think enough people have seen it before it slips into the nether regions of the forum.
I changed HSDPA revision to option 2 in band selection (HSDPA/no HSUPA). It worked off of airplane mode, which it hadn't done before but the same issue persists. When I get to work (where there is a clear HSDPA signal) from home (also clear HSDPA) it's on EDGE. During travel or when the HSDPA signal is not available, it'll just stay on that **** EDGE network even when I get to an HSDPA area.
Same problem on a clean stock rom ???
jje
Come to think of it, I'm not sure. HSDPA is new where I live but not where I work. I did, however, do a repartition in Odin of the JS3 firmware and then a wipe with Darky's 9.2 and 9.3. Of course I didn't really stick with JS3 for very long before flashing to Darky's ROM but this isn't a problem inherent in the ROM itself or others would have reported it. Furthermore, I've switched between kernels, file systems and modems and yet the problem persists. I haven't enabled any tweaks with any kernel I've used either so that shouldn't be an issue, should it?
Maybe try this.
Dial *#*#4636#*#* ->
Go to Phone Information -> and perhaps play with the Preferred network type?
If noen of your efforts have resulted in anything meaningful, the suspicion goes to your operator.
Hope this helps.
i have the exact same issue although 3G is available in my area when it once logs into edge mode it doesnt wanna change it. only when i restart the phone it logs onto 3G again.
pretty annoying
maik
You can go into wireless and settings, network settings, wcdma only, and then back to wcdma and gsm and it'll connect to 3g or H. At least that way you don't have to restart the phone every time it does it. The main thing is finding out what can fix the issue.
For some reason, the phone information settings don't stick. I've tried to use wcdma preferred but it just goes right back. The other code settings, on the other hand, work just fine.

I'm wondering if it may be a sim card problem rather then a phone problem. I'm thinking I should try my girlfriend's sim. I'll report back when I see if that's the problem. It'll be after work though so feel free to come up with other suggestions. I plan to do a write up in general, [resolved] if we figure out the problem so people with this issue can know what to do.

Not the sim. I also contacted my service provider to get a push of their latest update with tower location, it's not prl on gsm it's id-something-something. No change there really as far as the signal issue goes. I also checked my provider website just to see how much data I had used, not even close to the cap on unlimited.
I think i'll have to try a flash on odin with repartition to a stock firmware and then work my way back to see what may have caused the problem. It's a shame, really since everything else on the phone works phenomenally, it just won't auto connect to hsdpa which is spotty in my home and work area so it's a bigger pain in the neck then it needs to be if it won't switch between the two on it's own.

Hi All,
I am starting a new thread for India specific networks on the Bionic.
I am new to this so please don't mind if i write anything stupid which i may haven't understood yet.
I got my Droid Bionic running on Stock ICS from States to India and inserted a couple of GSM sims which worked fine for a while without any tweaks. I used my device for one whole day(made calls didn't test data) and when in the morning i woke up there was no network. At that time in *#*#info#*#* it was showing as detecting network but as soon as the location updated, GSM would show out of service.
What i have done so far:
1. I flashed Eclipse ICS v 1.2 ROM and got network though very weak but couldn't make no calls.
2. I got ICARUS HD - 1.6.1 and applied the tweaks as mentioned in phone and got network stength increased but still no calls but a strange thing happened when i tweaked with build prop editor running ICARUS HD, when i changed to WCDMA Preferred and turned radio off and on it registered on the network gave full strength and GSM: showed in service as well, though this was only for 10-15 seconds and i couldn't test call.
3. Now I'm running CM 10 - released on Jan 18th and to my amaze I can use 2G Data though GSM state is Emergency Calls Only.
Following might be helpful to understand:
Current Network: TATA DOCOMO
Signal Strength: -99 dBm 5 asu
Neighboring CID: Unknown
Cellinfo: Blank
Roaming: Not Roaming
GSM Service: Emergency Calls Only
GPRS Service: Connected
Network type: EDGE(Also shows EDGE2 at times)
Message Waiting: False
Call redirect: false
Call Status: Idle
Preferred network type:
WCDMA preferred
I have changed to gsm only, gsm auto and all others applicable to no help.
I am trying to run my phone in India on network: Tata Docomo which probably operates on 1800 or it could be 1900 on 3G.
One thing which i am sure of now is that this phone certainly has all GSM capabilities and its some tweak which is required which i cant figure out. I have personally seen my phone making calls and now its running data as well.
Please help me on this!
Seems like settings changed with build prop to run on T-Mobile or AT&T dont seem to work for networks in India. Tmobile operates on 1900 and Tata Docomo on 1800
One thing which wont let me sleep is that why did it run perfectly at first and why did it fail if i did nothing to it. Can the network block the IMEI or something of that sort happened. It's been two sleepless nights for me now, now praying to the Radio God!! LOL!
Did you manage to get it to work? You might be right in thinking that it might be related to IMEI. Did you try and find out if the IMEI is considered valid by your operator since this is not a true worldphone its IMEI might not be in their database?

Didn't work. I had to give up on it. There was actually no way in which i could get it checked with the network.
I sold it off on Craigslist last July!
I now have bought another one to test. Waiting to get back to India to test it again.
Not all bionic works with gsm, only wcdma. It's HW A after 36/11 and HW B

It's quite interesting that it did work perfectly initially and then with CM10, the data worked. Did CM10 rom include its own radio as well?
I found something interesting in this thread (not related to Bionic):
http://forum.xda-developers.com/showthread.php?t=945312
Good luck with your new Bionic! Does it work okay with GSM carriers in the US?
I finally got to try it and unfortunately it didn't work for me. Mine is HW A '12 Bionic and I am on ICS. If I go outside my house and search for networks, I get to see only one network(not mine). I see extremely weak signal in the phone info screen and also it shows gsm out of service. I tried 3 sims from different operators. Inside my house, nothing ever shows up. In other phones, I get to see many operators. Seems like it's definitely a signal strength issue if the gsm 900/1800mhz and wcdma 2100mhz bands are not locked. I'm not sure at this point what is the real cause. I even tried flashing just the radios from GB versions as complete downgrading is supposed to brick the device. Needless to say it didn't help. I'm still investigating and experimenting.

Hi,
I have now tried everything possible with the Bionic to run it on GSM network in India but it has failed to respond. I tried both hardware versions and can confirm that it is not registered as a world phone like most of new Verizon devices.
The worst thing which still bothers me is how and why did it work once(Yes, I made and receive calls on Docomo network in India). It will still show network strength , detect network but not register. I cant find no answers to it and have given up on this. The model is now obsolete and is clearly not a world phone in my dictionary but I won't deny it having GSM capability having seen it work personally. I have finally dumped the other bionic as well.
Good luck with your experimentation though!
has anyone noticed that the 4G on the S10 is quite buggy?
the speeds are extremely unstable, and sometimes completely unusable. (not a problem with the carrier, tried it on another phone and it's fine)
What I've noticed is that if it ever goes into medium power saving, 4G will stop working completely, it'll still show 4G, and i can still make calls, but no internet connection, even after exiting power saving mode. The only fix is I'd have to restart the phone for 4G to work again.
anyone have the same problem/ knows a fix?
I've read that I should do a factory reset, but I really want to avoid that, setting up the phone is time consuming.
Side note: battery life is not as good as expected, but that seems to be an issue for all exynos, not just me.
Same Problem here i unlock phone 4G shows but it tanke some time if i can use the Internet
Speed is Very slow and unstable
I am having connectivity problems as well. Keeps loosing the connection. I have to turn on airplane mode then turn it off all the time.
I don't have any problems with network connectivity, so far. In the link my result a moment ago: https://www.speedtest.net/my-result/a/4796337263
Hope you get some sensible connectivity soon. Cheers!
Same issue here! It was fine since I first received the device, but yesterday, I manually changed the network toggle to get better indoor signal. However, even after setting the toggle back to the original setting the LTE and data service kept dropping out. I tried manually toggling, switching network bands, etc... but nothing worked. It just keeps dropping data service.
I just hard reset the phone moments ago, and will update accordingly!
Update - Even after a network reset and hard reset it still dropped to Edge data a few times. However, after the last hour or so, it has locked back on to LTE+ and is holding strong. Seriously hope this is a software bug and not a bum radio chipset or antenna.

I'm on tmobile and my data is horrible in certain and what's weird I have all bars.

not sure if i should say that its good to know I didn't get a dud.
but man, samsung needs to get their sh*t together, this is not acceptable for a flagship phone.
looks like i'll have to do a factory reset soon.
I'm on tmo as well. I have a feeling it's just jacked up radio software. I did some more tweaking and went into band settings *#BAND# on the dialer and disabled all the LTE bands that aren't used by TMO and that seems to have helped as well. It think this issue is congruent to the known issue with Sprint devices trying to connect to incorrect bands. I haven't used it out and about yet, but it definitely helped my phone stay latched on to LTE from my home. Additionally, when it does drop to HSPA, it doesn't get stuck like it used to.
I recommend tweaking the band setting before doing a hard reset.
Update - still doesn't fix the problem. Pains me to say it, but I'm afraid I have a hardware issue. I'm going to try a sim card swap as a last ditch effort, but will also seek an exchange as well just to get ahead of the problem.

This shortcut only works on Snapdragon version, do you have Snapdragon with 4G issue?
This code only runs on the Qualcomm chipset version. Oddly enough, my friend with the Exynos version has no problems, even though he's missing a couple of TMO bands for the US.
Yeah I have Exynos S10+ as well and it runs fine on T-mobile USA

This code is not working on SM-G9730 Qualcomm Hong Kong version. Any ideas?
Same problem here. I got the snapdragon US unlocked variant using here in Spain and compared with my old Google pixel, they do not have the same speed LTE connectivity even using the same SIM card. I tried to force using the 20 BAND (800 MHz) but I dont really know how. My galaxy s10 plus is using the BAND 3 so it does not let it picking the fastest possible band in my city. Any ideas? I also did think galaxy s10 plus US variant did not have 20 LTE band, but I checked it and realize it even does. One more question, what is the difference between 4G and LTE? Here in Spain all devices are running 4G, not seen any device running LTE, but my new samsung does. How can I switch it to 4g or LTE+? Thank you everyone boys.
just wondering if anyone has gotten the ASCA/ASC8 update and can report whether this problem is solved wit firmware update?
Bands matter depending on where you are. Depending on your area, only specific bands will be used. However, some bands used, while not faulty, are easily interfered for some reason with cases or other obstructions like your hand. Most likely, Samsung is planning to give a large update considering signal direction. I would probably not factory reset if you have a lot of data, and the problem would probably come back.
I ended up having to send my device in to Samsung for analysis and repair. I'll keep everyone updated.
after ASC8 update, i think the problem has been solved, havent noticed any problems so far
