Hello everyone,
I have a Sprint TP2, which i have done the following in order:
1. Flash Hard SPL
2. Sim Unlock - (found out this actually wasn't necessary, but made donation anyway)
3. Flash Radio (2.05.00.WU)
The above all done according to instructions from this forum.
4. Plugged in a T-Mobile sim card, switched to GSM only Manual, found the network, made a call. Worked fine.
5. Flashed new Rom (EnergyROM_21864_RHOD500_09.Nov.2009_StandardM2.5)
Started using it on Sprint, everything was fine. Switched over the T-Mobile, seemed ok at first... but now problems begin:
a. Tried connecting 3G and get online via T-Mobile, seemed to work for a minute.
b. Tried using GPRS (2G, turned off 3G), seemed to work intermittently.
c. Noticed couldn't stay on T-Mobile's network, even though when signal was good.
d. I thought the data connection was causing the problem, but turning off all data connections didn't help. Gets connected, then soon gets dropped. Still couldn't stay on T-Mobile.
This same T-Mobile card works perfectly with the original T-Mobile TP2, and works find on another LG phone. So it's not the card or account issue. I don't know what could've caused this, is it the new Radio? or is it the Rom?
Can anyone give suggestions on how to cure this? Thanks!
James
**Edit - sorry, found the dialog is going on at another thread. But just thought this might need to be in a separate thread anyway.
I Am having a similar issue.
I too am having the same exact issue. Has anyone got the SPRINT: HTC Touch Pro 2 working on T-Mobile? I Have Both, The one for T-Mobile and Sprint.... I Just Like Sprint Phone a lot better.
i have the same issue. even when i go into the gsm/umts services and change the band to 1900/850.
i also seem to have an issue where it shows i am connected to the network and i can make calls and send text but can not receive them unless i manually reconnect to the network or do a soft reset.
i'm also looking for a fix for this exact problem
Similar problem with Sprint phone on AT&T network
I have a Sprint touch pro 2 unlocked, using on AT&T network. Thought it was working good, but now I see it keeps dropping me, asking me again if I want to connect to the network. I can toggle the Flight mode on/off, and it'll reconnect.
Anyone know a solution to this problem?
Hi,
I have an HTC One XL from AT&T.
It is SIM UNLOCKED and BOOTLOADER UNLOCKED. It is running CleanROM.
The problem is that my phone looses 3G connectivity and the only way to recover it it's rebooting the phone. The 3G still shows but there is no activity and the apps try to connect until they say "network problem".
I don't use it on AT&T as I live overseas. I do not have LTE so my phone is set to "WCDMA preferred"
I tried with other roms (CyanogenMOD 10, MIUI, etc.) and with almost every RADIO (flashing them with TRWP Recovery and wiping cache/dalvik after).
When 3G/HDSPA works, internet works really fast... but then it "disconnects" and everything sucks.
What do you recommend?
Best Regards.
Not a fix, but have you tried turning airplane mode on/off rather than restarting your phone?
I used to get this problem constantly with stock. Once I installed Viper, I haven't had a problem since. Don't know enough about radios to tell you if a new rom flashes a different radio though.
Try going into recovery, and wiping cache and Dalvik. Similar to area51avenger, I've had this same problem on a couple ROMs, and wiping cache and Dalvik fixed it. Might not work for everyone, but it can't hurt.
My friend i aleady tried that without any good result.

do you have the right APN? if you dont have the correct apn for the LTE network then it will drop connection whenever it searches for one. Maybe just run on WCDMA/gsm instead of WCDMA/GSM/LTE. It solved the problem for me on rogers here in Canada on cleanROM
I have the right APN.
Here we dont have LTE so I run the phone in WCDMA/GSM only... no LTE
Problem persist.
Also replace the phone IS NOT AN OPTION

Is there something like fast dormacy?
Please, need help.
I've had the same experience on both rooted and non-rooted HOX's with various ROMs. I have concluded that it has nothing to do with the ROMs and more to do with the HOX itself but only when not on LTE. Before LTE was turned on in metro Detroit I had this problem constantly. I use the Airplane mode trick to resolve the issue in most cases. Now when I'm in an LTE coverage area my data is very reliable but as soon as I'm somewhere that doesn't have it (rural areas or inside with a poor signal) that ugly problem returns. It sucks because it's clearly a widespread issue that may never get resolved and I don't know who to hate at this point.
I don't exactly know when it happened but for a little while now, I have noticed little or no 3G connection in my phone. When I switch it to WCDMA only mode there is no network, and when I try it on another phone I get a 3g connection. I have tried flashing RUU's and even on stock, I get no signal. I have tried flashing firmware.zip from various OTA's to get it to work but still no luck. So I am stuck on 2G.
Has anyone had this situation and perhaps solved it?
multiple users have this issue.
T-mobile once had a update to fix : "◦Improvements to prevent devices from getting permanently stuck on 2G when updating.◦Improvements to prevent devices from getting permanently stuck on 2G when updating."
http://support.t-mobile.com/docs/DOC-5224?AID=11456737&PID=4485850
but:
Symptoms
Device is stuck on 2G or Edge
Cannot connect or cannot stay connected to 4G
What happens and why
In rare cases previously, HTC One S devices may have gotten stuck on 2G after updating to software 2.35.531.7 710RD (now discontinued). In this case, they cannot connect to 3G or 4G anywhere.
The new software version (2.35.531.10 710RD) prevents working devices from getting stuck on 2G when updating, but it does not fix devices that have the issue already.

i do not think there is a fix other than replace the phone.
i have to reboot in order for the 4g data to work again but it only stays on for about a minute and then it stops working again. everything else on the phone works ( text, voice, wifi etc...) I read somewhere that flashing different radios might fix it but im not sure about that. anyone else experience this and have a work around? i am currently on baseband i535VRLG1
Thanks In advance
i called Verizon and they said it may be the sim card thats damaged. if that were the case wouldnt voice and text fail as well?

I'm having the same issues recently. I've always gotten a 4G signal at my house (albeit not the strongest one) but lately, my phone will not hold on to the connection. When coming off of wifi, my phone will not acquire a data connection at all most of the time. I can still send/receive texts and calls but there is no 4G or 3G icon, no MMS, and no data. I have to toggle the radios on/off, or change from CDMA/LTE to Global (or GSM) and back, put in airplane mode, or restart.....there is no guarantee any one of those steps will work. Sometimes I have to do it repeatedly until I get my data connection back but it is only temporary.
I'm on the i535VRBMF1 baseband and updated to the ML1 modem to try and resolve but to no avail. I have replaced my sim card (as I initially though that was the issue) but it has not helped either.
The only thing I can think of is that my PRL may have been updated (it is currently 15310) and it's causing issues with the towers in my area.
I just got back from Hawaii and was also in San Diego for a few days and had absolutely no issues. It seems to only be an issue now when I'm at my house which makes me think it is something VZW network related and nothing to do with my phone per say. It's really driving me nuts though.
BTW, I'm in Southern California (Irvine).
I seemed to have fixed the issue by reverting the baseband back to vrlf2. I had to switch from global to 4g/LTE because I vegan to inch roaming charges lol. Verizon credited me and no dropped 4g signal. So I'm happy.

What ROM are you running? I'm just curious what the implications are of running an older baseband (from the ICS days) on a newer ROM/Kernel.
I'm running cleanrom8.1 core edition. Slightly buggy but tolerable.
I was finally able to somewhat resolve my issue so I thought I'd post in case anyone else is experiencing something similar.
By using a few different apps and testing techniques, I was finally able to deduce that my issue had to do with EHRDP hand-off with the towers in the immediate vinicity to my house. I'm not sure what VZW did to them lately but it doesn't appear to be a problem in other locations so it seems like the issue is on their end (and not something to do with my phone).
In any case, it seems that when my 4G connection is weak and EHRDP is detected, it is dropping the connection entirely instead of handing if off to 3G (EVDO). The connection is also never transferred back when a 4G signal is detected either until I reset the connection where there is a moderate 4G signal.
Again, this only seems to be an issue when connected to the towers near my house and doesn't occur when traveling abroad.
To fix this, I have disabled EHRDP by doing the following:
1) Open the dialer and type *#97328640#
2) Select "[2] CDMA"
3) Select "[2] Data"
4) Select "[7] eHRPD e/disable"
5) Select "[2] Disable(*)"
6) Reboot the phone
Now my phone switches between EVDO revA. for 3G (using the native protocols) and LTE rather than relying on the broken eHRDP protocols. This workaround will have to suffice until VZW fixes stuff in my area but at least I don't miss MMS messages anymore.
Hope this helps anyone running into similar situations.
Hello. My issue is that my phone won't connect to LTE in stock ROM, but it connects with CM 12.1. But my main "concern" is that it used to connect to LTE using stock ROM... To make the long story short: when I bought the phone, it only connected to H, even if I selected LTE in Preferred Network Type (selecting LTE there even made, and still makes my data connection unstable, getting disconnected and rapidly connecting to data network, but only uses H network type) so I selected 3G, because it was made my connection stable.
Then, after some time, I decided to try and select LTE again, and it connected to LTE! Good, fast, stable connection. But after some weeks, I had to wipe my data partition, and again... it would't grab LTE. Some days ago, I flashed CM ROM, and I was surprised that it grabbed LTE with it again. And today, I decided to flash stock ROM again because CM gave me some problems with moto apps (I had to wipe data because it entered in a bootloop), and again, no LTE in stock ROM.
My question is, what can be causing this behavior? I didn't do anything to purposely fix data connection and use LTE, and my phone is capable of connecting to my carrier LTE band (i tested the speed when I was on LTE and yes, it was a lot faster than H), so it should be some ROM/software related issue. I tried to reset APN setting, connecting to the 2 APN that my phone has, and still won't get LTE.
Any ideas of what could be causing this behavior? Thanks!

dial *#*#4636#*#* and service menu will appear. in phone info menu select network type 'LTE only' and check your signal strength. if it's low like 1 bar in status bar that's why it keeps switching back to HSPA.
I won't connect if I select LTE only, it just shows "no service". But I have good signal here in my house, as I used to have LTE when this was working fine.

maybe carrier signal problems? you should check LTE signal strength on other's phone and compare with yours when it's available at your house.
and you mentioned it was working with cm12.1, try with it again or maybe ur harware was defected

Ok, I'll try again with CM again, but it used to work some time with stock too. I think it shouldn't be a carrier or signal related problem, but I'll try using my sim card in other phone, and try again with CM, I'll report back here after I test.
It seems to be caused because of the APN. I inserted another sim card to my phone and it added a new APN, and it changed the Network Type in phone info to "LTE/GSM Auto (PRL)" and now it works! Thanks for the idea!
But I still find it strange that it connected in CM from the start, hahaha
