A501 3G Issues - Acer Iconia A500

Hey All
Not sure who can help me here, but i am trying to upgarde to 3.2 which i have done with great sucess but every rom i try does not display either the wifi network i am connected to or the 3g network name or speed. It just displays (no service) when in 3G mode and nothing in wifi mode. is there a configuration i need to set or change in the config files??
Am running Acer_A501_1.309.24_EMEA_CUS7 as its the only rom (being the one that came with the device) that shows these notifications.

You'll find this is a common issue, as they port the roms mostly for the A500. Although the stock roms are more or less the same, the devs seem to only have A500's which means they don't/can't test them on an a501. So, they mostly leave that part out.
Sometimes, you can simply modify the "build.prop" file, and near the end, you can place a simple "#" on the line that says "wifi only". Usually I do this before I flash the rom (unzip and modify the system/build.prop using wordpad or notepad), then try the flash. This at the very least, opens the menus for network apn's. Doesn't mean it will activate the internal 3g if they didn't include the associated library files.
I've managed to play around the past day, and actually got signal strength on Revolver version 6. But no APN yet, so I suspect a couple files are missing from the rom.
Roms thay do work with the 501;
Taboonay ver 2.0. Also, after installing, I reboot again, and flash Thor's ver 3.5 kernel. Didn't have much luck with newer versions of both.
Honeyvillian from Richard Tripp. The earlier versions, not the most recent as I haven't tried yet.
Lightspeed,,,, I just didn't like it. Ran a touch wonky. Also have to use a patch for 3g.

can you please tell me how do i use 3g?just put the sim on?and if the tablet is bought from acer is it unblocked?

Well, this will depend if you have an ATT Acer 501. If it is the ATT model, it is locked to ATT network.
Usually you can tell when you start it, and have an ATT data widget. Or you can go to Settings, About Tablet, scroll near the bottom and look for the "Build Number". If it has ATT in it, well, it's a locked tablet.
Example : Acer_A501_4.402.03_PA_ATT or something similar.
Always insert the Sim card, with the tablet OFF. You might damage something if you try inserting it with the tablet on. The instructions specify this.
Normally, the tablet will recognize the Sim card, and by default will use the 3g network.

Where would I go about diagnosing connection issues? MDA+TMO

Not to give away too much specific information, but I've got a new TMO MDA and the building I am in actually has TMO repeaters. Other TMO phones get perfect reception, and I can even put this new sim into my old unlocked HTC Typhoon and get perfect reception, yet my new TMO MDA won't get any signal.
I'm attempting to scour the registry to find some bit of info or a bit to flip or something of that sort to diagnose the issue. Our TMO rep apparently has RF engineers working on the issue, but if I can fix it sooner than they can I'd be happy.
So, basically, only these new MDAs (other new MDA owners are experiencing the same issue, as well as SDA owners) fail to authenticate to the repeaters in this building. I doubt the repeaters have a list of phones that allow authentication, since the Typhoon was never released by TMO and that can authenticate fine. So I'm thinking there is some bit on the MDAs that is sticking to one band frequency or another, or something to that effect.
Any idea where I could look for info, whether it be a web source or maybe a registry key I could tweak or something of the sort? I got the engineer mode to work (after another registry tweak to turn it on), and it isn't showing any information since the phone isn't connecting to any tower/repeater.
when you go to select networks to use, does the phone give you a list of possible cell networks?
Sorry if i sound obvious....but:
1. Have you compared the Roms on the phones? Maybe the new phone has a different rom which is causing the problem.
2. Have you tried the phone anywhere else outside your building...
3. The engineering mode will still work even without a SIM installed, so if your getting blank information then I think you have an old Rom
Hope this helps
Answers to questions in the thread:
1. If I go to select my networks manually, and it searches for networks, all it finds is the Cingular network, which I can not connect to. It won't find the TMO network at all. But I know it exists because other TMO phones work fine with full reception, and even my old Typhoon works with my new TMO sim in it.
2. The roms on all the MDAs shipped from TMO USA 1.8.10.2 and GSM rom 01.09.10.
3. Phone works entirely fine outside of the building. The building is shielded, but there are repeaters in the building for current TMO users. I know they work since other TMO phones other than the new MDA and SDAs work fine.
4. As for engineering mode... interestingly enough, now that I do have reception (I'm at home right now), I also get blanks. I thought that because I didn't get any reception, I wasn't getting anything from the engineering mode. But interestingly enough, I still don't even though I have reception.
Methinks I do need just the GSM rom. Someone mentioned it in another thread in the Wizard Upgrade forum. Where might I get just that ROM, maybe I'll give it a shot and see if it fixes before doing a full ROM upgrade (which I'd like to do for performance reasons, but I haven't gotten a definitive answer whether I can revert back to bone stone TMO roms with extended roms and everything yet).
I woould suggest getting hold of one of the phones that works, back up the registry, and restore it to the phone that doesn't work. That would tell you if its a registry setting, or a phone/rom problem

Well, there are no phones that work.
The phones that do work are your run of the mill non-smartphone phones, not a WM5 phone.
Actually, that's not true since my Typhoon is running Windows Mobile 5, but it is entirely different than the MDA.
Only all the stock MDAs shipped from TMO are failing to authenticate to these repeaters. Makes me think that updated the radio rom would help, or something on the repeaters is blocking just these two phones (the Wizard and the Tornado).
Try updating the wizard with one of these roms:
ftp://xda:[email protected]/Wizard/Roms/Tmobile/
Well, I updated the radio rom to 01.12.10...
And still wont connect to these repeaters. The phone seemed snappier to connect when I stepped outside of the building, though. So there is a plus. However, there has to be some reason the repeaters in this building are not allowing my phone to auth.

Wifi to GPRS/3G

I have searched this and other forums and have not seen either this problem or an answer to it. Per AT&T's suggestion, I just upgraded to the new AT&T rom version that adds PTT and seems to have big problems. My current issue is that when I first boot up and connect via GPRS/3G all works well. When I get to a wifi area and switch to wifi, again all works well. However when I leave the wifi area (or just turn off wifi) I can't get any data via GPRS/3G. The balloon comes up saying it is connecting. The little "G" and bidirectional arrows in the top left indicate it is connected. However in the browser, it just continues to grind away with "Locating" in the bottom right corner until it finally times out and puts up a screen that says that the "page cannot be displayed because the connection was lost". I open the connection manager and press and hold the "Data Connection" icon until that goes off and try again, same problem. The only way I can get GPRS/3G data connection to actually work again is to reboot. Any ideas what is going on or how this can be fixed? Forgot to add that this is an HTC 8525. Thanks.
From your description I wasn't able determine whether AT&T's suggestion was aimed at remedying the issue, or if it's something that came about with the update.
Assuming the latter, you may want to try a hard reset first and run it for a bit before loading any other apps. Failing that, reflash the ROM. I had a lot of trouble with my radio when my 8525 was new, but it mysteriously cleared up after a few radio flashes.
Thanks but still a problem
Thanks for your thoughts here. I hard reset and reflashed.
Yes the firmware is the latest one that AT&T has suggested that everyone who had the older Cingular phones upgrade to. It provides the AT&T logo, the "push to talk" feature, and some other junk. I have contacted AT&T about this and their response was to send me a new phone that they claimed had the old firmware, since they have been getting a lot of complaints about the new firmware. It didn't have the old firmware and also it's SIM card reader appears to be broken. I called HTC and they said that they too have had lots of complaints about the new firmware quirks but had nothing to offer to solve them. Anyway, the old firmware had no problem switching between wifi and CGRS so I don't think it is in the hardware. On the other hand I'm surprised that nobody else is encountering the problem from the upgrade.
I'm having the same prob. Purchase three of these phones and the other users have little technical expertise. First I set up a sync with my office PC. Then loaded the ROM update. I run MAC's @ home had difficulty connecting to my home wifi. Finally determined that the 8525 would not accept the 13 key ASCII wep password. Needed to use the HEX. So I connected. Went to work and had problems syncing with my PC. Active sync had to rediscover the device. Now I'm back home and can't connect again. My Device ID changed names upon "resyncing" and I updated the Airport Base Station with my new name. I've spent a lot of time on this issue.. Maybe I need to send em back for an iPhone!
Well I found a solution to it
This is a great forum - though somewhat hard to search through thoroughly. Anyway the solution for me was to go back to ROM 1.34. Found how to do that through flashing from the micro card at http://forum.xda-developers.com/showthread.php?t=311704&highlight=cingular+8525+rom+version and getting the production ROM version at http://wiki.xda-developers.com/index.php?pagename=Hermes_Upgrades. Back to normal - everything works fine. Just for a trial, I also downloaded ROM V2.1.1 and it works find also - but sure seems a bit large - ends up with 42.9M of storage free vs V1.34 that has 50.25. Think I'll try the the memory expansion process at http://forum.xda-developers.com/showthread.php?t=298327&highlight=want+more+storage. That seems to at least provide a more than 9 megabyte smaller MBH file but I don't know what that translates to in memory usage yet.
Suspect there is a way to fix this problem but I haven't seen anything in the forums on it.

Finally Telus HTC Vogue WM 6.1/GPS rom update

Alright.. after much anticipation.. the rom release for the Telus HTC touch.
I randomly have been checking the site since I found the download page was updated on the HTC support page.. I ended up getting sick of the fact the the d ownload page was taken down so I copied down their server website and have been checking that. That is where the roms are actually upladed to so when the page is up it would link to the rom. Well on the server page (or whatever you call it) the telus update is there.
Check it out:
http://216.139.227.226/Telus/
So there we go. I'm going to flash my phone and see what goodies it does come with. Obviously rev A but I have my fingers crossed for gps too.
Oh and heres a direct link to the HTC support page for the Telus Touch... as you can see they havnt put up the download support page yet. So it was sort of a fluke I found this when I did as they havnt advertised it.

Had to call *22803 to program my phone (set PRL). That fixed the internet connection.
Rom works well, everything seems to be there. Have not had the chance to test GPS, yet.
will this work for bell phones too?
modified rom or official telus launch?
i have been waiting for this rom for a while. i knew it was in development and if you are wondering, the official rom will include rev a, location based services such as gps in google maps, tom tom and is bundled with Telus Navigator. It will enable threaded text-messaging, eliminate most of the freezing issues and help with bluetooth reliability. it also has an auto-pair with common passwords for bluetooth acc so it will speed up the process. my question is mainly to the starter of this thread? the file date i downloaded from the ftp site, is dated a few days ago and you said that you just found it. this does not seem to come from the htc site directly as most downloads come from members.american.htc.com unless thats just a masked address. simply put, is this an offical release or a modified version of what is out there?
i installed it and it works quite well, but i noticed a few odd things with it. the XT9 predictive is now not an option and its automatic for free typing fields, but you can't just turn it on by choice. internet explorer has crashed on me a few times, but this is minimal as i was trying to use the zoom out function on a content rich page. also, overall,t he device feels a little sluggish while going through the menus, but overall program support is speedy enough..
.
also, i happen to know for a fact that the telus rom version is:
3.00.661.1
but what you offerred as a download is:
3.07.661.1
why is it that this one seems to be a newer than the official one that telus released?
no, it wont work on bell, but the HTC website already has the bell update available... i don't believe the gps is unlocked for that model.
also, everytime you update the rom, all telus phones will lose their programming and you will need to OTASP... *22803 press 1 for english and 1 to program. as well, after it is done and the device resets... do the same, push 1 for english as well, but push 2 to upgrade the roaming list on your phone. it is import as you will have the most up to date preferred roaming list available from telus.
Hi mike.. I actually have NO idea.. The link I had (which is down now by the way) is the main server address for HTC.. if you were to go to say.. the altell support page for htc and click their rom download it will direct you to the http: 216.139.227.226 bla bla altell. same with Bell and the others. When I had orginall found this I figured that it would be uploaded there before there was a link put back up in the telus page since last time they did that and didnt have the rom I'm pretty sure they were bombarded with tons and tons of emails saying "what is going on wheres our rom!!!"
That said I installed it.. everything works fine. explorer hasnt crashed on me but I havnt messed around with it alot. I did however notice that my internet speeds arent any faster then they were before. I'm downloading between 700 and 850 kbps. Sometimes faster. But that was the same with the previous rom that was already on the phone stock. It also says EV in the top menu and 1x when its downloading sometimes. Not Rev A. The connection says CDMA1X (dial-up).
In regards to GPS I havnt been able to get tomtom to recognize the internal GPS yet. I tried using the gps launcher program which is supposed to prime it I think but still doesnt lock on. Once I switch over to my external bluetooh gps receiver it locks right away. So I dont even know if GPS works. I installed the telus navigation program and it said it was looking up the gps status and then found me on their map but I have a sneaky suspicion this might be through data.. I dont know though cause it was pretty damned accurate. Maybe I just need to try another gps priming program or something. Frustatrating though.
For those of you who have installed this do you have the same data info I have? the EV in the top menu bar? I could have sword I saw some screen shots of the rev A updates and it shows Rev A in the top menu. Maybe its cause I dont have it in my area? But I'm in London ontario.. so not some boon out area in the middle of no where.
Thanks guys!
ps.. any ideas on getting tomtom to work withought my external would be kindly appretiated as well. If anyone has been able to do so with this rom.
that sounds fair. i was just wondering if it was a hacked rom as i didn't want to bother upgrading it without something official. internet explorer hasn't caused me a single issue all day since then. i do find that the available memory has dropped to roughly 50 mb from about 70mb or so before with windows 6.0 and the device can get a little sluggish, but has yet to freeze on me once, which is a very noticeable improvement. thats interesting how the link was taken down and that would be really cool if we all got it in the nick of time. it wouldn't surprise me they pulled it with the touch diamond coming, it would be better to hold off and sell some of those and then launch the upgraded rom..
i can confirm gps works 100% for me. i used it in telus navigator and yes, it does use tower triangulation to assist in finding your location. i tried google maps and for some reason when i select "my location" it says my handset isn't compatible, but if you select use gps from the menu, then everything works 100% and my location shows right where you are and very accurately.
you said there is a program to prime the gps? where is that located? i still have yet to have an issue with it, but just in case. as well, i am unsure about the rev a icon, but it is still EVDO, just "revision A" i believe so i don't think the icon would change much

This Rom Saved My Telus Vogue !!!!!
A huge thank you to Aaron for posting this rom. I had given up on my "bricked" Telus Vogue on Friday and if it hadn't been way too hot Friday to go, I would have already been to the Telus store and bought a replacement. Make a long story short (am a newbie too) something went horribly wrong with the flash I tried. The boot screen still displayed the old version (2.36 i think) but some random boot screen would follow and that as far as the boot got. I tried flashing tonnes of roms but just kept errorring out. I happened to sit at the pc today and noticed a few new posts and 20 min later came across the Telus update by chance. So for a final effort I slapped the HTC onto a USB and gave it a shot. The first try was unsuccessful as windows suddenly recognized the handset as a PPC rather than the mass storage device it had been seeing up till then and jumped to Found New Hardware Wizard. Or at least thats what I think may have interrupted the update. I shut down the update after waiting 20 minutes and simply started it again. It picked up where it left off and now I have my Vogue back even better than it was.
So the reason I went through this long saga is #1 to say thanks and #2 to let anyone that thinks they killed their Telus Vogue............INSTALL THIS ROM TO BRING IT BACK!!!!
JAY
Jay,
Glad that this rom worked for you! Saved you alot of hassle with Telus I'm sure. I am already on my second touch from them as I had a dark spot on my screen show up about 3 months after I got my phone. So far this ones been pretty good and with this new rom even better. I've been reading up on some ways to increas the GPS sensitivity and locking on our phones and will post it in here shortly.
Telus GPS to Bell
I will wait for someone to rip out the portion for the GPS to port it to Bell.
It should work in theory considering they are both the same phone/cdma.
Alright.. Thanks to

the settings should be as follows
Allowed = checked
Assistanc-Spherical = checked
PDE IP Address = 216.198.139.92
PDE Port Number = 8889
PDE Transport = IP
Position Calculation = PDE
This process is a bit.. not tedious or anything but just safty's sale for a good read look at the thread linked below for a guide to getting the QPST program working.. how to get it to connect to your phone etc. Side note.. You have to install the WModem drivers on your computer in order for it to connect properly and you'll need to install the GetSPC program on your phone in order to get the service programming code. That said.. you also need to download the QPST program (obviously). All of which (including the guide) here: http://wiki.xda-developers.com/index.php?pagename=TitanGpsFix
You'll need to run the GetSPC program on your phone. when you open QPST and you add the COM4 port and you open the service programming it should say your ESN HEX at the top put that code into GETSPC (again GETSPC runs on your phone) and then it will generate your SPC..in the service programming click read from phone and enter the SPC it generated for your and it should work. Thats the code you need to get access into the phone via QPST.
Now follow that in order to connect to the program and go pretty much to where you have to put in all that information ghettofreeryder gave us. Make sure you redial the ##3424 code to get out of the settings in your phone.
Then once that's done. Download a1Jatts smartgps cab which will activate the smartgps in the registry of the phone. Do a soft reset and you are good to go. Make sure you put in ALL the right information. I forgot to put in an 8 in the PDE Port Number at first so I had 889 not 8889. I didnt get any quicker locks so checked and put in the right number and worked like a charm. I got locks on 6-7 satellites in my basement with a few seconds.

Wow. That procedure was really frightening. I got it working and it was well worth the hassle. Your addition (missing configurations) was needed for me too. I hope for poor average Telus users that they release a final ROM with this sorted out.
Edit:
Every time, before using this, an already established data connexion is needed BEFORE looking for GPS satellite. The GPS will not establish the connection if it's not there. A simple solution is to open Google map and move the map up to a download is required BEFORE making the GPS satellite connexion.

The wiki procedure have been experimented on many device/carriers.
But I think "PDE IP Address = 216.198.139.92" is carrier specific.
On another forum, a Bell user reported using the Telus leaked ROM with that procedure but with IP=195.207.101.126 and got it working well.
no internet.
i tryed calling that number *22803 after updating rom from telus. still no internet connection. any reason why or what else i can do?
First time i tried with Telus support center, they gote me goiing thrue the french portion of the programing (#2). After that did not work, I did it again in English and it worked perfectly.
So here it is in detailes.
Call *22803 + press 1 + press 1 again. Whait till its done then the phone will reboot.
Call again *22803 + press 1 + press 2. Dont remenber if the phone reboots again....
This should work.
If not, try pulling out your batery fo 15 sec. Then restart your phone.
Thats all the info I have got from telus service.

[Q] TMOUS HD2 Not showing correct signal.

I did a little searching around but didn't find much useful.
Anyways, About a week or so ago my HD2 running ChuckyROM-23125-Tabtastic.Jun.30.sfx, started displaying only the E for Edge data speeds. Normally, I would always have an H.
Any help?
May be the Rom, were u always using this Rom? Do you have the latest radio or software update? If not try updating your software or radio for your band. You can also try a different Rom to see if you have the same issue.
Good luck.

That's odd that it would start acting that way out of the blue (which is what you're thinking, I'm sure lol).
I don't know for sure what's causing that, but here's where I'd start:
-Make sure that your network settings on your data connection haven't somehow gotten switched to "GSM" instead of "WCDMA". If you see the setting is at "Auto", then go ahead and select "WCDMA" and see if that clears it up
-How old is the sim card in your HD2? If it's more than a year old (i.e. you brought it over from your previous phone), you might want to get a new one from T-Mobile...it seems that older sims can have compatibility issues with the new HSDPA network that's being rolled out.
-If neither of those two help out, then try a flashing a different radio (just do NOT use any .51 radios, those will brick your US HD2). I know the one you've been using has worked fine until now, but again with the backend changes Tmo is making on the network, it's possible that the one you have just doesn't do as well in your location anymore.
Other testing methods I'd suggest include seeing if you have the same issue in other areas than you're usually using, and also see if anyone else you know in the same area on Tmo is having the same problem.
i believe it may be my SIM card. It is over two years old and has been on every phone i've owned(about 6).
Also, i couldn't find anything about changing from GSM to WCDMA, only something about enabling and disabling HSDRA/HSUPA

Yes, I'd def say it's time to get a newer sim Please post back here and let us know if that resolved the issue.
In the settings tab on your slider, click on "wireless controls", then tap the "phone" entry (not the swich, but the bar to the left of it), and on the following screen scroll to the bottom and choose "change baseband"...then you'll see the options there under "network type."

[Q] Help with data and GSM losses of connection

I own a Verizon Motorola Razr M, bought in ebay to an US seller. I am in Spain and I use Movistar SIM card
The phone came with stock JB 4.1.2, and therefore I could not unlock the bootloader.
I started using it, but it had a problem that I am not been able to solve so far: after some hours of use, with no problems with GSM and data connections, it suddenly looses both connections, although the signals on the status bar still appear. I take care that signals have gone when I take the phone to make a call or surf the web.
I have tried the following procedures:
Change the net settings to GSM/UMTS
I rooted the phone with motochopper 1.1.2 exploit
I installed Safestrap 3.12 in order to be able to install other available locked compatible roms.
I tried these roms, following this thread here in XDA: Clean ROM 1.0. Clean ROM 1.1, Barebone New Base, Stock Deodexed.SDswap-Locked & UnLocked BLs-xt907-9.8.1Q-94-1, but no luck. This last one uses the last radio, but no way.
I also installed the [PATCH][GUIDE] Patch to fully enable GSM on Verizon CDMA Android phones. I could only install it on Clean ROM 1.1 however. It has been impossible to install it on the other ROMS. In any case, no luck again with the patch installed. Here I had a big problem because as I still had these problems, I got into *#*#4636#*#* in the dialer, and touched the band selection option: suddenly, the net showed no signal more and I was unable to make it work again: I finally solved this by installing the stock firmware from here with RSD lite.
No way. I still have this problem and I can not use the phone. I have also tried with another SIM card, but the problem remains. It is a shame because when the connection works, the phone runs very well.
Any help would be very appreciated

I tried these roms, following this thread here in XDA: Clean ROM 1.0. Clean ROM 1.1, Barebone New Base, Stock Deodexed.SDswap-Locked & UnLocked BLs-xt907-9.8.1Q-94-1, but no luck. This last one uses the last radio, but no way.
I also installed the [PATCH][GUIDE] Patch to fully enable GSM on Verizon CDMA Android phones. I could only install it on Clean ROM 1.1 however. It has been impossible to install it on the other ROMS. In any case, no luck again with the patch installed. Here I had a big problem because as I still had these problems, I got into *#*#4636#*#* in the dialer, and touched the band selection option: suddenly, the net showed no signal more and I was unable to make it work again: I finally solved this by installing the stock firmware from here with RSD lite.
No way. I still have this problem and I can not use the phone. I have also tried with another SIM card, but the problem remains. It is a shame because when the connection works, the phone runs very well.
Any help would be very appreciated

The problem also seems to become worse with the use of the phone: at the beginning, coming from a factory reset, It can last some hours before the problem occurs. But since it happens from the first time, it happens more and more frequently and the phone can not be used any more. It seems that there could be a software issue.
Another try disabling fast dormancy
I´ve just disabled fast dormancy, because my operator Movistar apparently does not use this technology.
For this, I have modified 3 lines from build.prop system file, as indicated in another site.
The 3 lines are:
ro.mot.ds.fastdormancy.disable=true
telephony.lteOnCdmaDevice=0
ro.telephony.default_network=3
Having fast dormancy enabled when your operator does not support it, seems to drain battery, and could cause other problems. That´s why I´ve done this. I have used root explorer apk from Google store, it is free and it automatically creates a backup of build.prop file when you modify it.
I keep the fingers crossed, let´s see what happens.
Fast dormancy: yes but...
After some days using the phone with fast dormancy disabled (for this, I also added this line to build.prop: ro.ril.fast.dormancy.rule=0 ; I read this for ICS Roms, I do not know if this command is also valid for JB, any comment will be welcome), I still get some cuts (less I would say), but at least the phone tries to restart the connections. For this, I have also installed the apk from Google Play called 3g reconnect.
In any case, any comment would be appreciated.
Issue not solved
I still get data and voice disconnections when I use GSM/UMTS or only UMTS modes. They occur ransomly, and they also occur as soon as I use a WIFI connection. I can only use the phone on GSM only mode, which is frustrating.
Any advise?

I do not go near *#*#4636#*#* anymore. So tell me do you use that to make these changes (phone info is the app name).
Choosing GSM/UMTS or GSM only

Hello,
I have tried both: using *#*#4636#*#* or using the usual phone settings. Sometimes I have also checked that the changes made with the usual settings appeared also dialing *#*#4636#*#*.
Yesterday evening, I tried selecting global mode instead of GSM/UMTS and it seemed to work for some hours, but today morming, the problem occured again. So far, the unique way I have found to avoid connection cuts off is using GSM ONLY mode. I have to say that I have tried with 2 different SIM cards but the result is identical.

Did you select the 3 dot menu & mess with the "band" settings?

I did that once, and all the signals disappeared. I restored the phone with RSD Lite, that appeared to be the unique way to have again signals working. Now I do not even dare touching these 3 dots.

What booby a trap? How many step into!
I don´t know if I am understanding you. I did that once because I did not know what else should I do to solve the problem. I saw that there was the possibility to choose theoritically between US bands and Cellular, and I entered in that menu. It is not so stupid to try that if you have already tried 100 other ways.
In any case, anybody has an idea about how to solve this problem? I´m sure I am not the unique person having this issue with this phone.

You are saying the problem is now still there. Yet the radio partition is fixed. Please restate what has been fixed with the rsd flash & what remains unfixed.
Well I think I have fixed and solved the problem: I initially copied the APN settings I had with my previous HTC Sensation, because the phone operator was the same (MOVISTAR), the SIM card too, and I have not moved. In these APN settings, the proxy was "undefined" as well as the proxy gate. I wonder if the radio stucks looking for a proxy each time or whatever. I tried yesterday with completely different APN settings, with a concrete Proxy and a gate... and now I have not had any issue in the past 24 hours. I will still wait a couple of days to see if that was finally the reason.
Which in any case would be silly, because I just applied what was working OK with my sensation, but...
New APN settings: let´s see

After several days, the problem is still there. After setting new values in APN, it happens less often, but it still happens. I have to switch to GSM only mode.
2 days ago, I was surfing the net at quite high speed with no interruptions, for half an hour. I then shutted off the screen, on again some seconds later, and the connection was blocked, I had to restart the phone. It has to be a software issue.
I finally sold the phone
After concluding that I could never get rid of this problem, I sold the phone, informing that he would have to use mainly GSM only connection. Great phone otherwise, but with this issue.
This sounds like a Baseband Issue.
Europe I have found baseband:
sm_bp_101031.027.32.81P to be the most stable so far, with no H+ support though.
But most Carriers in Europe don't have H+ or LTE.
That baseband is part of build 9.8.1Q-66
Which can be all downloaded here:
http://sbf.droid-developers.org/phone.php?device=8
The baseband from 98.16.1 had H+ support in Europe but connections dropped like crazy.
Same with 98.12.4, we remedied that with Aussie Radio at the time.
Maybe this may help some International users with Data and GSM Loss

I'm on 9.8.1Q-94-1(98.30.1.XT907.Verizon.en.US) and wanna use it in Germany. any experiences with the radio compared to the suggested one. Or is there another way to boost the performance of the razr m? Compared to my razr I the signal and data quality is really poor...
edit: my baseband-version is: SM_BP_101032.021.32.80P
edit2: ok... now i've flashed several basebands... and the behaviour of the phone is always the same... with the australian baseband of xt905 it wasn't possible to get an hspa-connection. dunno if its enough just to flash the radio-fw?!?!?
so is there an other way to get more stability in my region? i tried to flash the radio from razr hd retail germany. but i think the razr m don't like it when I fool around. actually I love the mobile, so i don't want to make it angry... your suggestions are very much appreciated...
