I don't know what you are all talking about. I had absolutely no problems with mms'es on stock, even without GoSMS Pro... Its matter of configuration.
[Motorola Photon Q 4G LTE] wintrxtrem:
Are you going to try a Sprint SIM? Very interested to see results.
[Motorola Photon Q 4G LTE] Skrilax_CZ:
Nope, I'm going to use Verizon, because Sprint sucks. I got rid of the CDMA switch using QPST, but the phone doesn't want to connect to GSM carriers :|
[Motorola Photon Q 4G LTE] wintrxtrem:
Even with radiocomm edit and running GSM CM10? :(

Did you try Straight Talk ATT SIM or other prepaid service?
[Motorola Photon Q 4G LTE] Skrilax_CZ:
I actually discovered a nasty thing - the unlock edit doesn't work, it reset to 01 after reboot (stock JB). Also not getting Verizon, because they require month-to-month contract (w a nonrefundable deposit), so gonna try AT&T with another phone.

Fixing the SIM Socket

Did you fix the socket? How?

Thanks.
[Motorola Photon Q 4G LTE] kabaldan:
I just checked it on my Q, and the NV 8322 does stick to 00 for me.

Make sure when editing it in RadioComm that you don't delete the "01" using backspace (and then write "00"), instead highlight the "01" and overwrite it with "00".

Another difference may be that I've done the edit already under 4.0.4. So if it doesn't work on 4.1, try to go back to 4.0.4 to make the edit.
[Motorola Photon Q 4G LTE] Skrilax_CZ:
The reason is that NV edit not sticking: opening up radiocomm, doing the edit, and setting GSM mode will work (along with the auto CDMA switch disabling - but unsure it that happened because of the lock). OK, let's see what happens when I downgrade to ASA14.

EDIT: You have to use fsg.mbn from ASA14 and then the edit works. With JB one it won't register under T-Mobile or AT&T network.

So to make this work:

1) Open up QPST, UMTS or GSM tab, and disable automatic network type switch

2) Flash fsg.mbn from ASA14

3) Do the unlocking mod.

TODO: On every boot it switches to CDMA, so you have to manually switch back to GSM. So I guess to make a small change in CM10.2 that will kick it back to GSM.
[Motorola Photon Q 4G LTE] aaron83:
I received some pretty convincing evidence today that the service loss issue is in fact a hardware issue and related to the SIM mod - see attached.

I guess the connection to the SIM was lost for a long enough period this time that the phone actually noticed it and reported it as removed.

As usual, everything was back to normal after a reboot.

Sucks, because I'd gone almost two weeks without a single issue after turning LTE off. Thought I'd found a solution (or at least a workaround), but I was wrong. It actually happened twice today. First time was seemingly at random, I just took it out of my pocket and it was gone. No error message, just unable to connect to anything until a reboot. Second time, though, was after I'd been screwing around for nearly half an hour trying to get Wi-Fi tethering to work; I never succeeded, but in the process I'd turned wi-fi on and off several times, had the screen on for a pretty long time, but perhaps importantly, the phone had gotten very hot (or at least pretty warm).

Could heat be related to the problem? During the two weeks(ish) when I had no problems, the battery usage was also fairly conservative, probably because I had LTE turned off. I'm not an electrical engineer by trade, but I did go to school for it and I know that heat would change electrical resistance (among other things). Maybe the mod is stable at room temperature but not at higher temperature? This is probably something that could be tested...

Anyway, just thought I'd throw in whatever new info I could muster. Hope that this twice-in-one-day thing was just a freak accident and that the losses don't get more frequent over time, otherwise I might have to give up this great phone.
[Motorola Photon Q 4G LTE] sub205:
Maybe it has something to do with the wire length?

First of all, the wires used in the generel mods are not shielded / twisted in any way.

Second, depending on the wire gauge, the simcard may not get proper power from the phone. A simple capacitor directly soldered to the socket may fix this problem.
[Motorola Photon Q 4G LTE] ujoty:
Like I wrote earlier in this thread, all that kind of problems dissapeared for me when I soldered wires directly to SIM card. Before that I had issues with NoSim card/Invalid sim card about once a day or even more frequently when phone was hot...
[Motorola Photon Q 4G LTE] aaron83:
Could be. Cornholio did my mod so I'm not sure what he used in terms of wire. Also don't know if soldering on a capacitor is just going to fix the problem without creating other problems in the process. (It might, but I think it would depend on how isolated that circuit is.)

One thing I forgot to mention in my earlier post: I go in and out of the service area (underground parking lot) at least twice a day, and the phone recovers with no problem. Generally when I'm on the train or in the station I also see it flip from 3G to 2G and back. The phone never has a problem doing this. There were some posts in this thread several pages back suggesting that the issues could be triggered by these protocol switches. While it is possible that they are a contributing factor, I seriously doubt that they are the root cause.

Far more likely, in my opinion, that dropping down to 2G is just a symptom or warning sign - that when connection to the SIM is momentarily lost (or maybe just partially lost?), the phone thinks that the signal was lost and tries to compensate by switching to 2G.
[Motorola Photon Q 4G LTE] ImaginationStation:
I have the same problem as you. I'm on Rogers and my symptoms are exactly the same.

I haven't figured out exactly what it is but I've considered heat. I also took apart my phone once as it started to get worse and noticed 2 of the mounts for the SIM card slot were broken off.

Yes, it always gets worse. At first it might lose connection once every 2 weeks and the only way to restore it is to restart the phone. Then as it gets worse it will work its way up to dropping on every call or every few text messages. After dropping and restarting hundreds of times I'm planning on opening the phone for the second time to figure out what the problem is. But this time I'm considering just soldering right onto the SIM card rather than fixing the slot.

The reason I have always considered heat is because the back of the phone is very hot when it drops the SIM, but originally if you keep the back cool it didn't drop the SIM as easily. I also use a cheap SIM card slot so I'm not sure how the contact material likes heat and/or if the contact fingers on the cheap slot are so thin that they start to flatten out and lose connection when they get hot. So it is probably a compound problem of heat and bad SIM connection. I was thinking about trying the i9300 SIM slot as recommended in this thread but I don't have time to repeatedly open up this phone and change things.

I got a local place to do it for me since I didn't have time to mess around with it a few months ago. I wish I just did it myself.
[Motorola Photon Q 4G LTE] tobby88:
Hi

I just got my three modded Photon Q on Friday. Mod was done by Cornholio.

First one loses GSM about twice a day. More often when I am moving. Less when I don't move the phone. When I take the train for longer distance I can guarantee that I will lose connection at least one time. But no invalid sim messages, it just finds no gsm and says "only emergency calls allowed". Reboot and it works again.

But the letter 'H' on the keyboard sometimes only works when pressing it a little bit harder.

Is the keyboard broken?

Second one loses connection after a few seconds, sometimes it takes a few minutes. But not longer. Especially when I do a call. Then it holds connection only for a few seconds. Mostly it says "invalid SIM", sometimes it just looses gsm connection and doesn't find a signal anymore.

Did the Mod go wrong?

I am just testing the third one... Let's see if this one works better...
[Motorola Photon Q 4G LTE] ujoty:
Ahh yes, aside Invalid/No Sim Card error, I also got lost GSM signal on which only reboot helped. I really got mad at this phone. I re-soldered/exchanged the cables/slot couple times with very minor help (if any). I really wanted to have a SIM slot, then I reconsidered (how often do I remove SIM card from a phone... never, only when I buy a new one) so at last I soldered the same cables (only desoldered from SIM slot, not from PCB) directly to SIM, and all my problems are gone. Not one signal drop, Invalid/No Sim card error.

Bent battery

While disassembling I managed to bend my battery a little. Returned it to it's original state, while I still haven't put it back together. Could this be an issue ? Also damn soldering cables to the SIM connectors is so hard.
[Motorola Photon Q 4G LTE] drkham:
Damaged board

Helo!

First, let me say a big THANK YOU to all hackers who make our phones live in full.

Now the problem:

I have removed the metal shield and (after a lot of trying) the SIM IC.

While soldering a wire to one of the contacts I managed to tear it off (I am pretty shure that the copper was torn away) - it's marked on photo.

Is there any way to remedy this?

And I also realised that a resistor is missing (the 1712 one on the picture).

Is it too late, or can this be MOD still be made?

Many thanks

After update to stock 4.1.2 --> CDMA

Hi Cornholio,

I received the updated phone today and started to test it. GSM worked and I was able to make phone calls.

After several updates, the PIN was not asked anymore. This happened after stock update 4.1.2 via RSD lite.

Now theSIM Card app says:

SIM card: absent

Phone Type: CDMA

I installed the skrilax 10.2. Happened with nightly 30.10. and 29.10.

Any ideas?

BR ovinator
[Motorola Photon Q 4G LTE] CornholioGSM:
yessss....switch it to gsm/umts and restart
[Motorola Photon Q 4G LTE] KylarBStern:
Fail...

I have the exact same problem, the exact same resistor is missing and I think there are 2 missing actually and not one but am not sure. I've soldered my card to the board and changed the settings of the phone but to no avail, I don't get a signal and the phone doesn't recognize the card.
[Motorola Photon Q 4G LTE] wintrxtrem:
I thought domestic GSM was blocked.. yes no?
[Motorola Photon Q 4G LTE] arrrghhh:
Well, if you can put any SIM in... It's only "blocked" because the SIM is soldered to the board AFAIK.
[Motorola Photon Q 4G LTE] wintrxtrem:
So it's possibly not also blocked through radio firmware like the first Photon..
[Motorola Photon Q 4G LTE] arrrghhh:
Ah, I wasn't thinking about the radio firmware block...

I would think since they soldered a SIM to the board, they wouldn't bother with such a thing - but who knows...
[Motorola Photon Q 4G LTE] Maxpowersxp:
all credits for starting this mod go to CornholioGSM

As promised my mod is done fully working in canada on bell and rogers.

some notes:

-the mod too me about 2 days to do 1st day was desolder and dremel to fit the sim reader that i took from a BB 9000(RIP after the removal of sim reader)

second day was solder and reassembly.

-the full size sim fits fine but i needed to sand the sim down a little at the end just so it fits better under the case, if i cut the sim a little this would save me from shaving off the cover inside.

-i could not find any headphone wire around so i used some cables from an old laptops monitor, seems to work well.

-the difficulty of this is mod is defn up there and thats just because of the size of the solderig required, its tiny and you have to be super carefull of other items around the solder points.

here are some pics :victory:

i am from germany and i want a smartphone with a hardware keyboard. the motorola photon q looks amazing but have no sim card slot. :/

would it be possible, to buy something like this: (it is from the iphone4 a micro sim card slot)

http://s1.directupload.net/images/121104/alwlnwe4.jpg

and add it into the photon q ?

how many "space" is availible inside the smartphone ?

is the soldering really hard ?
[Motorola Photon Q 4G LTE] CornholioGSM:
....ip4 slot is too much large :(

Soldering is not hard, but you must have hotair and solder station.
[Motorola Photon Q 4G LTE] americanpittbull:
So there is no possibility so add a sim card holder on the original space? Because a removable sim car would be nice.
[Motorola Photon Q 4G LTE] pujdo1:
if it is to large, how has Maxpowersxp added it ?
[Motorola Photon Q 4G LTE] CornholioGSM:
....the best way is found and then solder on mobo nano sim slot...

Maxpowersxp method works too but is not estetic beutifull :)

The best way is go to operator and tell him for 2nd sim card. Then you can have one soldeted inside phone and one as reserve sim for another phone :)
[Motorola Photon Q 4G LTE] pujdo1:
yeah but i am from germany i would import the photon q, but i would have to solder a sim card on it. or are there other better tutorials
[Motorola Photon Q 4G LTE] ogrfnkl:
Thanks, that's great!

Do you think this iPhone 4 micro SIM connector will work? They have tons of these on eBay, but unfortunately they don't specify the exact dimensions... I guess since its contacts are on the bottom, I could glue it upside-down onto the Photon Q circuit board, and then attach the leads.
[Motorola Photon Q 4G LTE] flintston314:
How about using some Dual-Sim Adapter instead of a tray? These might be possible to be soldered directly.

If anyone is willing to offer that as a service, please contact me. Looking for someone willing to take money for soldering something that can take my sim onto the deivce :)

for any one who has this mod DO NOT UPGRADE to 77.8.10.XT897 it brakes gsm data.
[Motorola Photon Q 4G LTE] Herby6262:
Very noob question - what is the big benefit to a process very involved like this? Does it more benefit outside the US? Allow you to use all towers not just Sprint? Keep contacts synced with not just google but on the SIM now too? Derrrrrrrrrrrrrrrrrr
[Motorola Photon Q 4G LTE] ogrfnkl:
This mod is for people who want to use this phone on a different, GSM-based carrier. It is also useful for those Sprint customers who want to be able to use a different carrier's GSM chip on trips abroad to avoid paying Sprint's exorbitant roaming charges.

---------- Post added at 11:27 PM ---------- Previous post was at 11:13 PM ----------

Yeah, a nano sim connector would be peachy, but where can you find such a beast? I've looked high and low on the internet, and NOTHING! Micro size connectors are hard enough to get, as you have to order from a components dealer, who usually sell in bulk. The only ones available on eBay are the iPhone 4 micro sim connectors, which I was hoping would work, but you say they are too big!

Do you know the exact dimensions of an ip4 connector? I've looked for that information everywhere and couldn't find it. I just want to be able to compare it to the generic ones that you can get from parts suppliers (which can be as small as 13x16x1.4 mm).

Maxpowersxp's mod looks like he used a MINI sim, not a micro sim. If so, that's why he had to cut holes and machine down the plastic around it. I would think a micro sim holder should fit just fine in the space available. I just really hope the ip4 connector would work, as it's the only one that can be easily obtained on eBay.

Thanks!
[Motorola Photon Q 4G LTE] Maxpowersxp:
the connector might work it would have to be mounted in the same spot as i have my regular sim slot. it would have to face outwards from the phone(small problem as the antenna is a sticker in that spot) say you trim the antenna down without changing the length of it. regarding all of that the width cannot be wider then 16mm as it has to fit between the speaker and the hdmi slot iv dotted them with green

i have the back off the phone as update killed 3g data so here are some dimensions the sim slot area. i listed the length as 21 tops as the back side slopes down towards the side
[Motorola Photon Q 4G LTE] ogrfnkl:
Hmm... I can't be sure, but it looks like you've chosen a different spot for your sim holder from that suggested by Cornholio. There is no speaker visible to one side in Cornholio's photos and videos. In any case, the spot looks big enough for just about any micro sim holder. These usually run around 14x16x1.8mm. Some are even smaller than that. What I'd like to know is how big the iPhone 4 micro sim connector is exactly. I've looked for that information high and low and couldn't find it. The reason I am interested in that particular connector is that it's so easy to get on eBay, whereas the others would have to be ordered from wholesale suppliers (mainly in China), who sell only in bulk.
[Motorola Photon Q 4G LTE] flintston314:
As that micro sim card connector ist only 2,90€ I ordered one. I assume it´ll take some time to reach me, but once it´s here I can post dimensions.

Edit: Actually it was 5 connectors for 2,90....these are really cheap :)

Giving 4 away to the one person willing to solder that thing into my photon q (in Europe) ;)

[Motorola Photon Q 4G LTE] ovinator:
Thanks, it works now.

I had to go back into stock ROM first and enable GSM there BEFORE flashing CM. Then it works in CM as well.

In my first try I installed stock ROM in CDMA mode, did not switch to GSM and made a reboot. I directly installed CM on top of it. CM was starting in CDMA as well. I was not able to switch to GSM due to the error message "com.android.phone crashed".

It works now:

Install stock Jelly Bean, switch to global mode and GSM/UMTS and make a full reboot.

After that I installed CMW and CM10.2/GAPPS + delete data and cache.

Now it works.

smd resistors and capacitor lost

Hi! Something stupid happend when I unsoldered the Sim-IC ... I removed unintentionally the two smd resistors and the capacitor.

(I attached a thumbnail) Now the phone isn't working anymore, it stops at the bootloader unlock warning.

Has anybody a clue what I can do now or can anybody tell me the values of the resistors and the capacitor?

A small feedback about the Sim Mod.

A small feedback about the Sim Mod.

First…. CornholioGSM made a great job.

I use my Photon Q since June 2013 in Germany, daily for lot of calls, mails and so on… and all this works fine….no connection lost…3G works fine too.

My phone:

-	Stock JB 4.1.2

-	Deodexed

-	Extended power menu 98.10.5

-	TWRP 2.6.3.0

I made some modifications on my phone and it works fine for me :))

The best improvement was the voice quality and the signal strengths.

Below are the modifications, maybe it helps other.

1. I renamed following files as .bak :

SprintCBS.apk

SprintDataService.apk

SprintExtensionService.apk

SprintInstaller.apk

SprintOMADM2.apk

SprintOverlayProvider.apk

SprintPhone.apk

SprintPhoneDataService.apk

SprintRoaming.apk

SprintSettings.apk

SprintSystemDataService.apk

Note:

Keep in mind, this Android Version was designed for Sprint Network…and the outside of this Network it’s not necessary to have this Sprint modifications.

E.g. C_Spire has not these files.

2. Modifikation in file: framework-res.apk\res\values\bools.xml

<bool name="config_unplugTurnsOnScreen">true</bool>

<bool name="config_allowAllRotations">true</bool>

<bool name="config_intrusiveNotificationLed">true</bool>

<bool name="config_cpuPowerSaveSupported">true</bool>

with the following I could improve the voice quality and signal strength

<bool name="disable_vzw_specific_ad_rules">true</bool>

<bool name="vzw_connectivity_service_init">false</bool>

<bool name="config_start_sprint_extension_service">false</bool>

<bool name="config_sprint_connection_service">false</bool>

<bool name="config_ftr_37719_sprint_remote_lock">false</bool>

After all… I am satisfied and it works flawlessly, it’s a big improvement compare to the Stock Version.

But you know…you do these modifications on your own risk !!

Attached some screenshots.

-----------------

Btw:

Losing Signal can also depending on the provider... region...location (e.g.in a buildings)...and so on… and not every time on the phone itself.

I friend of me he has an IPhone 5 (same provider) and has problems with bad signal…losing connection and he has the latest OS.

I tried CM 10.1.3 and CM 10.2 (almost latest nighly) and I stay at JB 4.1.2.

Note 1:

I forgot.....I made also some mod at the build.prop file.

[Motorola Photon Q 4G LTE] drkham:
Just a little follow-up:

I managed to make it work by shorting the missing resistor and I soldered the wire for the missing copper directly to connected resistor.

Now phone works.

However ... it works with two different Slovenian providers (one is a virtual operator - Izimobil - using Mobitel's network, and the other is Si.Mobil), but for the third (T-2 Mobile) the SIM card isn't recognized.

When phone is started with T-2 SIM it never asks for PIN and also doesn't say that SIM is not present. Phone never registers with network and if I want to manually search for network it says "Error while searching for network".

There is one speciality with T-2 SIMs though:

They have SIM toolkit (I think it is called this way) with special menu for Roaming (T-2 uses national roaming and international roaming provider)

Does anybody have any idea what could be done to get T-2 SIM to work?
