T-Mobile MDA Keys Hang.

Hello everyone,
I am new to Windows Mobiles. I have bought a used T-Mobile MDA (HTC Wizard), The problem with this is all the keys except Power Button, Align Screen & Camera button hangs after a minute or two the mobile is turned-on. Nothing works. I have to use soft keys to make a call. If I press Camera button the camera interface appears, when I close it, all keys started to work normally but again after one or two minutes it hangs and I would have to again use the same technique to make them work. Sometimes all the keys work normally for more than a minute but again hangs. I have searched in all the system settings & I can't find any option to configure it. I have searched many threads on this site to solve this problem but can't find the appropriate answer. It seems to me someone have burned wrong ROM or did something wrong with its ROM for which it is acting like this. Given are the specs of ROM.
IPL/SPL = 2.26. G3
T-Mobile ROM.
I am using SIM of my operator other than T-Mobile. (SIM Unlocked)
Also If I try to Hard-Reset the phone, When It say me to "Press Send to restore factory default settings or anyother key to quite", All keys hangs and I have to make a soft reset to get into working.
Can anyone tell me what the problem and how can i solve it ?
How do I know whether its CID Unlocked or not ?
Does Upgrading/Reinstalling the ROM will solve the problem ?
Is it hardware problem ?
Thanks in advance.

One more thing
I also have did a hard-reset by following the given procedure.
Start->Settings->System->Clear Storage.
It installed the OS after boot and my installed softwares disappeared. Which means it really hard-reseted itself, But still the problem isn't solved.
I am pretty much sure now its ROM/Hardware problem !!
Any idea about the solution ?

Have you tried to flash a new ROM yet? That may solve the problem, it made my power button work again.

I'm not sure, but that sounds to be seems like hardware problems. I'm not sure if that screen actually has anything to do with the ROM at all, which at best, it is IPL related? I would suggest you to try an offical T-Mobile ROM, which includes everything (i.e. IPL, SPL, and ROM) and see if this problem persists.

Can't find the official T-Mobile ROM.
Thanks for your replies. Can you please tell me from where I can find the Official T-Mobile ROM, I have searched on this site & xda-developers ftp site a lot, Some links are broken and somewhere FTP requires authentication. Also can't find it on Google. I think ruu_prodigy_1081002_104_10910_tmo_usa_ship is the original ROM file but can't find it anywhere except the T-mobile site which require a valid T-mobile no. Can you post some valid like here to download the file.
Thanks again.

If you were to go Wiki, at the ROM table page, bottom line, you would to find this
http://www.tm-phonedownloads.com/
which should be a global site (if not US site), and if you go into it, 'MDA Vario', there is a ROM EXE to update to AKU. I saw it as UK which probably because I have an UK ip, you try going in and see if you have US version instead.
Also, for the TMobile US, you can consider getting a PAYG card just to get a valid tmobile number to get into the page to download stuff, IF you are sure there are something there (e.g. and if PAYG is cheap)

Ok, I got the UK version. I'll give it a try.

Well, I have tried Official ROM. But the problem is still there. I am also now pretty much sure that its a hardware problem. I guess the mobile needs to go to scrap now.

[Q] Eclair 2.1 No Network

Hey.
I updated my LG Gt540 to Eclair 2.1 and I am really happy that I´ve done that.
As I wanted to use the internet (no WiFi, i think its called GPRS) it doesn´t work.
My question is, why is it so? Can I bring it back to work?
TehBone

Check apn settings
Sent from my GT540

go to network settings and select your 3g network provider manually.
if that doesn't solve it, you'll need to flash another rom. I don't have internet on the baltic rom, but no problems with the open europe one. have no idea why that is...

THX.
Can I check my APN with APNonoff or another app?
Ehm. I don´t know if network is the right word for my problem. So in german its something with the internet. So the Internet (no WiFi, WiFi works well ) does´t work.
TehBone

O.K. I have a Problem!
As I wanted to update to an open European rom, the OS seems to be a bit broken.
Evertime I did anything a small little Windows Pops up, that the OS ist broken.
What do I have to do?
As I boot the Phone again it stops with the "LG"-Logo. How can I do an downgrade or Update or anything else, so that the Phone works again?
PLS Help!!!

MMS settings dissappear after I bricked/fixed my phone, stops working in Mango

I have a problem, I have looked all over the phone and I can't find MMS settings...
Checked in the EM menu and in Settings/Cellular
EM Menu (I get a matrix photo when entering, lol)
-Phone Information
-System Information
-RD Test
-CIT
-Protocol
-Service Center
Even doing the "qwertyuiop" trick It stills doesn't appear
PD: I did the TouchScreen update to 2.0 from EM menu, this bricked my phone! But since I fixed it, I can't use the 7720 update (Mango) or my phone goes dead again(touchscreen not working and if used the phone restarts).
Also changed the original 8gb microSD for a 32gb and working perfectly even doing updates, flashing, restoring, etc... it's like if I had the original memory.
Also tried with earlier versions 7004, 7392 and some other version... (Pre-mango) in noone of these the MMS settings appear in the EM menu.
OS version: 7.0.7403.0
Firmware revision number: 2250.1500.7004.105
Hardware... : 112.576.2.0
Bootloader version: 7.27.1.0
Any idea of to get MMS settings? (or also any idea to get my phone working like if it were new? So I can have everything working as it should again... to restore the touchscreen firmware or all the phone firmware)

Have you figured this one out? My nephew's phone doesn't have the MMS Settings in EM also and we're stuck.

Uninstall the old em then dial the em again.

[Q] Mobile network disconnects when the screen is off

Hello,
I've noticed something strange this past month. I was getting data disconnections and I could'nt figure out why. Each time I look at my phone, turning the screen on, mobile network (voice + data) is missing for a few seconds, and comes back.
Now I know that if I keep the screen on for a while (I tried more thant 1 hour), I don't loose the network, but if let the screen go to sleep I immediately loose the network (I don't receive whatsapp messages in background), and when I turn the screen on, it comes back.
Weirdly, when my phone could reach 4G, I had (almost) no disconnection. It only happens in a 3G, edge, or nodata zone.
I changed my carrier (I just moved from europe to New Zealand), and it doen't change the problem.
I'm using CM11-Nightly (sept) on a I9505. I tried installing an old nightly(from july), and it was really full of error messages, so I switched back to a recent nightly, but in the meantime I had no disconnection.
Thank you for your help

I don't know exactly where this option is, but it's for battery saving. You can choose that somewhere in your settings I think

I think that's true for Wi-Fi, but I never found it for network.
And now it seems that network won't come back if I don't go to airplane mode and back to normal mode.

I'm having the same problem, seems to mostly affect lollipop installs.
Did you find a solution?

No I didn't. It seems that somewhere in july 2014, CM11 included a new version of the modem. So every CM11 build after that and every CM12 build is affected (I don't know about other roms).
I read that it was the way the modem handled finding the best network method. With the previous modem (v5 ?) it tried to get LTE, 3G, etc... but now it fails when it fails to get the prefered network.
4 solutions:
- flash the modem (didn't try it, don't know how)
- You're supposed to be able to choose you're prefered network in the options and choose 2G/edge. Didn't work for me but I'm interested in your feedback.
- get an old version of CM11
- live with it (my current option :'( )
There is maybe another solution, I'm not an expert, just a desperate user.

Hey again, I did fix it for myself.
The modem is the problem (I flashed my modem, and my bootloader just to be re-up-to-date).
If you want to get lollipop for yourself you should do it, its not too hard
Its listed as Qustion 14 on this here page: http://forum.xda-developers.com/showthread.php?t=2419762
I don't mind trying to give some pointers if you need help understanding how to do it, but I did this at 5am while sick so my memory of what I did is not 100%, never the less I would like to help if you need it.

Thank you for the advice (you came seeking for one, and ended up helping me ).
How did you choose which modem version to pick up ? the latest ? Do you have to do it after every CM upgrade ?
Edit:
I found the latest version from one of your links : http://forum.xda-developers.com/showthread.php?p=50965837#post50965837
Is the "Combined package - both modems in one flashable file." ok ?
And what does flashing the bootloader do ?

"What it does"... I am not 100%, I assume it initialize some part of the system, HW or kernel level, but I might be way off.
In any case I did use the dual modem pack to flash both "PHONE" and "PDA", another thread I asked in just replied to another user with the neccessity to flash the new bootloader aswell (dont know if the version numbers applies for you):
u must be using a 4.4.2 baseband and bootloader .. just a 4.4.2 baseband will not work .. once updated ur set

My question is on this page a bit down, and some replies a bit further down than that:
http://forum.xda-developers.com/showthread.php?t=2735248&page=116
Tip: I had to save the PIT to a file (did it twice to be sure) with heimdall before using odin to flash (couldn't get heimdall to work for that part), all because odin would not play nice inbetween loading the PIT from device and flashing, this might not be a problem for you at all so it's just an FYI.

I managed to flash the modem & the bootloader. So far, no disconnection, so I'm quite happy.

Network not registered issue

Hi Guys,
I am writing this Thread believing that I will get a solution as Yota company has not provided any solution after 15 days trouble shooting. I just brought the phone from Russian seller through eBay.com to India and after 2 months of fight from the local customs office I just got my phone. I was very happy and was floating in air to have the first dual screen phone in my hand. The phone was flawless with dual screen was working awesome. The phone came with lollipop update. I switched on the phone with out inserting the simcard, the phone prompted for a small 350 MB update and I just update the phone. Then I just inserted the Simcard after which i started facing issue. The issue was the phone is able to read and shoe the service provider name but there was no network signal and it was showing only emergency calls. When i tried to make calls it showed network no registered. I tried with different simcard which resulted in the same issue. I though it might be a simcard issue and checked with my old phone but there was no simcard issue. So i just contacted the Yota tech team through mail to help me on this issue. They asked me do some basic troubleshooting but there was no use after 15 days they asked me to ship the phone to nearest service center which is in Russia. The issue is to and back from Russia customs will cost me the price of 2 Yotaphone fist generation phone price. So I through of resolving this issue myself and researched in online. I found that Samsung phones were also facing the same issue after update and tried all the solutions given in internet but there was no use. Finally there was a solution asking to root the phone and install the ariza patch which would solve the issue. I just rooted my phone and when I installed the ariza it showed it was not compilable for yotaphone 2. I just searched in XDA forums and could not find anyone reporting the similar issue with a solution. So I through of creating new thread in hope of getting a solution in this issue. Please help me in this issue by creating a patch or any solution which will me help me out of this. I am not able to use the phone as the basic call function is not even working reset the phone is a heaven.:crying::crying::crying:

Do you still have this problem?
I wasn't sure at first, I thought it was my sim card, but I have tried 2 different networks sims and they both get no signal in my Yotaphone 2...
The network's name does appear, so the sim must be being read somewhat, but I always get no signal.
I literally have no idea what to do.
I too turned the phone on without a simcard, flashed the RU latest rom, flashed TWRP, rooted it etc, surely that has nothing to do with it...?

@bharath9962 ! I fixed it!
I have no idea why this happened, and I spent a few hours trying to fix it, very angry. I downgraded to 4.4 to see if it would help, put back the native China rom that came with my phone (accidentally deleted my backup too...)
I bought a new sim card just for this phone because the old one did not 'work'.
This is not a popular phone so it's hard to find information, anyway... I'm very relieved now. I can only imagine you gave up...
I found the answer here - thewichitacomputerguy.com/blog/how-i-fixed-your-sim-card-does-not-allow-connection-network-g1
1. Open the phone dialer
2. Enter: *#*#4636#*#* (Once entered, you will be taken directly to a "Testing" page) [4636 spells INFO]
3. Tap Phone Information
4. Scroll to the bottom of the screen and you should see a button that says radio off. Hit this button and when it reads radio on Hit it again to turn the radio back on. <-- (Not a Typo)
I rebooted and waited a few seconds, no signal. I turned on airplane mode, turned it off, and it worked!
Now I can go back to RU 1.99 and reinstall all my stuff...

My country is in Asia but I believe this does not matter - the problem was that somehow the radio (cell phone function) was 'off'/glitched, and had to be turned on+off to make the phone function again. Using a different country's sim card would not fix this problem.
As I wrote above, we both share the fact that we first turned our phones on with no sim, and updated. Maybe just a coincidence...
Just try the guide and please let me know if it is fixed!

Hello!
I try to figure out what you did but I get stucked in number 10.
Actually I flashed my Yotaphone with the chinese radio the first time, but I don't get good connectivity.
Anyways I try to do what you wrote, but when I tipe the first line (first fastboot command), cmd keep saying waiting for the device... maybe is that I'm impatient but nothing happens.
I try other USB ports and nothing works...
So actually I don't know if I'm doing it right or if I have to wait for a longer period of time (10 minutes or more).
Any help would much appreciated.
Cheers!

Hi there,
you don't have ADB drivers installed. Google for "universal adb driver" and install. There is driver included with yota 5.0 firmware (C:\Program Files (x86)\yotaphone_flasher\Driver\Google), but any other adb driver should work as well.
And use original yota usb cable!!!
It shouldn't take more that a few seconds for those commands to execute.

Had the same problem
Hi all, I had the same problem when I flashed russian firmware (YD201) over my phone which originally had honkong firmware (YD206).
I can inform that for me it also worked to flash the Chinese firware with yotaflasher.
However, when I tried to only flash the radio, it seemed it did not work. So I flashed the complete chinese kitkat firmware with yotaflasher and then afterward just removed/renamed the radio folder when flashing the newest russian lollipop firmware. Everything working great now, even was able to do some ota's without any problems since the ota's did not update anything of the radio img's.
And indeed you first need to make sure that you have the fastboot drivers installed and your device gets recognized as fastboot device by your PC.
You can test this by doing "fastboot devices". If you device turns up there as a fastboot devices, then the drivers and connection from pc to phone are ok.
Good Luck!

Thank you deepmnd and tomgaga.
Actually I had to activate developer options... And then reinstall the ADB cause, aparently I had it but it didn't work.
After that the instructions worked perfectly, but I still have network issues.
I don't know if it is because I have a MVNO (Mobile virtual network operator) and the phone has to change between the networks ( the one that provides the network and the MVNO).
I think that when it changes from one net to the other is when I lose connectivity and sometimes I have to search the network and choose it manually.
So this problem actually happened to me and the solution was to activate Roaming services (but I dont' know if is actually the same problem).
Anyways I can see that I connect to EDGE, HSPA/HSDPA and LTE.
For sure there is a way to monitor the network and check wich ones works.
Another guess is that being a phone for the chinese market, and the lack of the 900mhz band is causing this ¿?
So at the moment I'm losing signal just by walking on the street and I live in a big city. It seems that LTE and H works fine but I don't have a a way to assure this.
When I will have a spare time I will try to reflash the phone with the instructions deepmnd provided and see if it will work.
Thank you for your help!
Any advice will be appreciated!!
Update:
I try tomgaga approach I will test it just to see if is the network or my provider

Does anybody know which bands different firmwares support?
Reception is incredibly bad in my case (206 flashed with EU firmware).
It'd be nice if somebody has any info on unlocking different bands for yotaphone2.

I have the same problem as you, I will try this weekend to downgrade to the older chinese rom and check if the reception get better.
And if then to the latest RU rom.

I have the same problem as you, I will try this weekend to downgrade to the older chinese rom and check if the reception get better.
And if then to the latest RU rom.

Thanks for that, it helps a lot to clear the situation regarding the two models.
Now, taking in account deepmnd´s solution above, would it be possible to find those missing bands from the original 206 which are not available to the updated (and then international, 201-) version and add them individually, file by file via the fastboot flashing?

I followed deepmnd's instructions, and my phone now connects to GSM/EDGE, which was not possible before using the EU Radio (latest EU rom). Thanks for this!
Unfortunately it now preferably (!) connects to EDGE, although the LTE/WCDMA-Option is prioritized. I can force the phone to connect to WCDMA by using the WCDMA-only-option, but in this case it does not commit a fallback to EDGE if 3G is missing and I have no connectivity at all, unless I change the band-options and force a connect to EDGE. I'd like it to switch between the bands automatically, as my YD201 did without problems (in Germany).
Any hints to solve this problem?
Thanks in advance, Knut

Fix for Yotaphone 2 YD206 from China
If you already flashed the phone to latest EU 5.0, you can skip 1-5
1. download via FTP: fw.ydevices.com/YotaPhone2/YotaPhoneFlasher/yotaphone2_flasher.exe and install
2. run flasher and download latest EU rom (2 - 5- 7)
3. turn off the phone and turn it on while holding volume down - this will boot the phone in "downloading..." mode
4. in the flasher press 1 (Flash the cellphone)
5. the phone is now on 5.0.0-EU1.1.124b and 2G is not working at all and 3G is connecting only to 2100 MHz (on my cell network)
6. download via FTP: fw.ydevices.com/YotaPhone2/Firmwares/CN/4.4.3-S01-003-CN1.0.3.32a.zip
7. unzip the file and copy \radio to c:\program files (x86)\yotaphone_flasher
8. run cmd and go to c:\program files (x86)\yotaphone_flasher
9. repeat step 3.
10. run next lines:
fastboot flash modem radio\NON-HLOS.bin
fastboot flash sbl1 radio\sbl1.mbn
fastboot flash rpm radio\rpm.mbn
fastboot flash tz radio\tz.mbn
11. reboot the phone and enjoy 2G and strong 3G signal

Thank you! I had missed calls and did not know what caused them. Then I noticed this happened when I was not on LTE network but on WCDMA or 2G network. And this seems to have solved the issue for me as well.
