Help invalid or missing Sim anyone had this - JASJAR, XDA Exec, MDA Pro Software Upgrading

Hi,
Here is the problem and the options that I have tried...
The phone works for some time, during this time I can receive and make calls. But suddenly it pops with a message "Invalid or Missing sim card. You can still make emergency calls if your service provider permits"
If I switch on the inflight mode and switch this mode off after 2-3 hours, it starts working. But the same message pops up after some time.
Below are the steps that I tried:
1) Upgraded the ROM to v1.13.188 (from O2 site)
2) Upgraded to Windows Mobile 6.0
3) Hard reset and soft reset etc...
How ever after the first upgrade of ROM it worked continusly for 3 days, but now it doesnot work for more than 2-3 hours, back to square one.
I havent tried the sim unlock. I couldnt find the unlock code and process from the link you had mailed.
Hope this will help you in suggesting the next steps to fix the issue.

Hi,
Please let us know the Rom version and radio stack you are using.
Have you tried downgrading back to the WM5 Rom and seeing if the problem persists?
I would guess that it is a dirty/damaged Sim card, have you tried cleaning the contacts on the sim card itself........... you can do this with a pencil rubber.........
Try the steps above and try another sim if u have one available, failing that post back some specific information on your Radio and Rom Versions.
Cheers,
Beast

happened to me too (after I dropped my JasJar)
I'm sorry to tell you this but the issue is not your software image.
This is a hardware problem.
I can tell you my JasJar dropped to the floor. phone speaker stopped working (but came back after the 2nd fall).
I then started to rarely get this "invalid SIM" message. I ignored it at first.
but it got more and more frequent until the phone was no longer usable.
I didn't change any firmware during that period. I blame only the crashes.
Something there must have cracked. cleaning the hardware didn't help for me.
I finally gave up and sent it to manufacture labs.

I had same problem and had to send it in and imate replaced the board for me and since it was within warranty it was done for free

ROM: 1.13.82 WWE
ROM Date: 11/30/05
Radio Version: 1.04.02
Protocol Version: 42.37.P8
Extended ROM Version: 1.13.188WWE
How ever after the first upgrade of ROM it worked continusly for 3 days, but now it doesnot work for more than 2-3 hours, back to square one.
and it hasnt been dropped so why would it work for 3 days then start doing this

Same Problem
Hello again,
i have the same problem, i search for a result but now i upgrade the radio, but now i cant flash the radio again, it start to hang at 11%...
I had a similar problem on my Wizard one time.
I ended up fixing it by flashing on of the giant original shipping roms.
The rom includes everything and was the only way I could recover from the corrupt radio flash.
Hope this helps you.
Try testing your radio with other sim (some other operator's sim
is prefereabile, in your region)
hopes must not die. I will work again

these problems are caused be something glitching up in the flash, not the sim

Try to flash again, i had same errors after i flashed some different ROM`s.
What i remember just right now:
I get a new sim card on thursday since then i have this no GSM error.
Now i`m scared to setup my connection because the device is running.
Had some connection losses but as long its working...
Not really.... i open Programms and scroll down then windows hang.
No UMTS connection i bought it because i want to read my emails, not just to make phone calls .
And to be honestly : to flash around
Still looking for a solution for that no GSM error.
Thank you for your attention.
Same Problem
I got an replacement from At&t because of the white screen effect on the Cingular version.
As soon as I load in the sim it gives me a no gsm message..
so i load up black X rc and the newest att radio and i still get the message..
So finally i hard reset a couple of times and it goes away..
Now the only thing is that the connection reset a lot and even flashing back to the original raido with an downgraded ipl and spl still doesn't solve that. I even got a new sim and no luck.
I even went to the point of simunlocking it and it still doesn't work.
Keep in mind that this is the new att 8525 and the cingular 8525 worked better even it i cudn't see the screen..lol
you guys have tried the file off this page, right?
http://www.america.htc.com/support/8525/software-downloads.html
yea i tried the one off htc's website i get an error about 11% thru, any other ideas because im going crazy i have no gsm no phone service no service period!! HELP!!!
Yes, the latest supported wm5 is the one i had originally.
Any ideas from anyone?
hey..... just for understanding....
ur RADIO ROM version is - 1.16.00.00. Hope you know that this has to be separately updated, and is not included in any of the ROMs available in the cooked format e.g schaps....
may i suggest that you upgrade to one of the latest RADIO ROMs, available here - http://wiki.xda-developers.com/index.php?pagename=Hermes_ExtractedRadioRoms
The 1.48 RADIO ROM seems particularly stable all around the world, so go ahead and give it a try - ftp://xda:[email protected]/Uploads/Hermes/HERM_Radio_Only_1.48.00.10_CustomRUU.rar
After that, you could choose Schap's latest ROM and upgrade to the same; and check if things work out.
EDIT: I see that you have flashed different radio roms already......
NOOB's ANSWER TO THIS PREDICAMENT: Downgrade to the offficial radio and ROM. And see to it that you restore your SPL i.e., follow the procedures of removing olipro.... and take it to your nearest O2 dealer...
Maybe this helps ?
How about this one:
Flash your ROM radio etc.
Take out the battery for 20 minutes.
Yesterday i flashed the original O2 ROM after it said No GSM again.
I was mad and took out the battery.
In the morning i inserted the battery again and since then no problem.
To test this if its really working i flashed a HTC ROM, after configuration etc. i took out the battery again, waited ~ 20 minutes.
Because it said no GSM again after flashing HTC ROM.
Looks like its working (for me)
Edit
No its not working
The original O2 ROM was working almost perfect just flashomanianing it back ... Hope it will work .
similar problem plz plz help
hey.. i would really appreciate if you guys could help me out with this one (i am a noob =(( )

Flashed WM5 same error = No GSM
Sometimes it shows No R No G
Tested it with 3 different operators sim card.
Setup a complete new OS on my notebook (because i thought a virus maybe and it corrupted the downloaded files).
During the flash process i even dont breathe but no help
Flashed HTC ROM with radio 1.47... interrupted the second update/setup process.
Was ok for 3 hours.
Are we all just beta testers from HTC and MS ?
Im still getting the same issue. Although I unlocked and superCID the deviece I will try to get a warranty exchange on it. It was messing up before I did any of that so I don't think that it should matter. I just want my old Cingular 8525... but i guess i have to keep on trying until I get a good one.
Hi did you ever find a solution to the radio rom flash hanging at 11% i have the same problem I can flash the os but the radio rom always hangs at 11% so nice pda no phone options
Ladies and gentlemen, I had the same problem, and I fixed it. Here's my story.
I was an idiot one night. Pulling my trusty 8525 from my pocket to read a text message, I instead dropped it. On its face. On pavement. From waist height.
I know, I cringed, too.
Ever since then, I got the No GSM error, and radio ROMs refused to flash beyond 11%, except the original factory ship ROM which got as far as 12%. Everything else worked perfectly except the radio.
I took it to one of the IT guys at work who suggested that I may have damaged something on the mainboard, but here's another 8525 you can play with if you want, because it's in the recycle box and will be going out the door to be recycled soon and we won't see any money out of it anyway, so here, it's yours.
Problem was, 8525-b had video issues. SOMETIMES would get the whitescreen. ALWAYS wrapped the bottom ten or fifteen rows of pixels up to the top of the screen. But the phone worked flawlessly.
Then, I discovered that the "video card" is separate from the main circuit board. Therefore, 8525-a had problems with the mainboard, and 8525-b had problems with the videoboard.
The solution presents itself.
Took them both apart, took the mainboard from the 8525-b and installed it into the 8525-a.
My Hermes is back. Everything functions flawlessly, including the radio. And everything flashes, too.
Point of the story: I don't know if you dropped your phone or if maybe something else may have caused some damage, but the only way that I was able to work around the radio rom flash hanging at 11% issue was to replace the mainboard. I got lucky, I was good friends with the IT guy. But I was never able to find another solution.

Need help guys!!

I live in Bangladesh. Recently I visited Malaysia and bought a Dopod 838 Pro from there. I checked it over there and it worked fine. But after getting back, when I tried the mobile with my country's SIM, it gave a error message saying ' your current network 47001 is not supported, please ask your device vendor for an update' and I got a no service problem. In the available networks section my operator (GrameenPhone) isn't listed.I tried almost everything I could, upgraded to SPL v.7, tried different radio versions, tried different ROMs and modified windows mobile versions like Black version, Pays version etc. The best I got was I got a signal for 2-3 mins. During that time I could make and receive phone calls, it worked fine for that short time. But after that 2-3 mins. the signal drops and the phone starts checking for the signal and eventually I get a no service problem. I tried repeatedly but with the same result. This is so frustrating!!!! I love the phone, how can I make it work?? Hey guys, help me out please. Thanks.

Have you tried to SIM unlock it?? Take a look in the upgrading forum...READ READ READ before doing anything else ok?
Try a different more newer SIM card, or maybe a different provider!
Re:
Tried unlocking, different provider, different SIMs, everything I could think of but alas nothing worked. Any other ideas guys??
Still no luck guys!!
Hey guys, I'm still stuck with my problem here, appreciate your help. And I also need the radio ROM version 1.40.30.00 (that's the only radio ROM I couldn't try because when I clicked on the link shown in the forum I got a '550 Failed to change directory' error. Could someone plz re-opload the radio ROM somewhere and send me the link. Thanks.
Phone problems
Make sure you are SIM unlocked and not just Device unlocked. They are two different things. I've heard of some folks having to repeat the process a few times for it to "take". Good luck.
Hmmm... If an IMEI is reported as stolen etc would it cause the phone to work for a couple of minutes and than lose service? This may be something for you to check into. Just my 2 cents.

No GSM/No Service on XDA IIs (BA)

Hi,
When i first got my BA, i upgraded from WM2003 to WM6.
This worked ok for everything (A few glitches here and there but i could live with them), but then, my phone battery had ran out, i charged it and loaded it up again and it now shows No Service on the today screen, so I can't make any calls off it.
I also noticed that when the phone boots it shows No GSM where it used to have 2 different numbers.
I've tried reflashing it to WM5, and also to WM6.1 but both of these didn't seem to fix it. The WM6.1 version I used can be found here http://forum.xda-developers.com/showthread.php?t=390862
Is there anything I can do to fix this?
Thanks!
Yes, fix is quick and easy and you can do it even at home: a soft reset.
Hi,
thanks for your reply,
I have tried soft and hard resets but this doesnt seem to fix it.
I wanted to try upgrading my Radio rom but when I ran the updater I got error 114. I'm not too sure what this means though?
Thanks!
Solution against "No Service" issue
Have a lot of Siemens SX66's. Just took one and ran unlocker, then flashed WM 6.0 and upgraded radio to 1.15.00. After that inserted SIM card and saw permanent "no service" message. Tried HR few times for no avail. Here's what really helped: I ran universal unlocker once again and then did soft reset. Voila! System booted and connected to GSM network. Hope somebody will find this useful.
Hi, All!
2 Larik007:
Did you have similate trouble with radiorom?
I have analogic problem with my BA (iMATE PDA2K)
At boot screen I see
No GSM
D 6.14 WWE
and boot process stops at this position.
Once my BA was booted up with this trouble, and goes to reboot and all repeats again.
I can't reflash radiorom.
At 61% I have "Error 114: Radiorom upgrade error"
I tried to reflash radioroms from 1.02 to 1.15, but nothing positive.
:-(
Can anybody help me?
No, my problem is because of some kind of error during unlock process, I guess. And your problem appears to be similar to "No GSM" issue of Hermes phones. But it may be repairable unlike Hermes ones...

I have the same "no service" issue. Can you give me a link for this magic universal unlocker
- what is this anyway?
Thanks!
http://wiki.xda-developers.com/index.php?pagename=BA_Unlock_Sim
Look for a link under word "this"
i had this problem, heres what i did that made it work,
1.re-insert the battery
2.press the on button
3.press the reset button TWICE
EVERY time you turn it off and on do this, but if you reset the phone you dont need to do it twice.
hope this works as it did for me,

Partial solution for "No signal" problem
I think the idea was posted by xplode sometime ago- I spent a day playing with it, but it finally worked for me.
0) I had unlocked BA with 2003. Later on I upgraded it to WM 6.1 and then at some point I've got this "No service" issue. I upgraded my Radio to 1.15 (it did not help me- but I did this in the very beginning, so may be it matters)
1) I downgraded ROM to one of 2003 ROMs (xplode has a collection: http://tinyurl.com/cozbbx)
-) downgrade instructions are in here: http://wiki.xda-developers.com/index.php?pagename=BA_1.40.00_Upgrade
2) I unlocked band page for the network connection- it was discussed in (http://forum.xda-developers.com/showthread.php?t=297099)
2.5) I finally used this cab : http://forum.xda-developers.com/attachment.php?attachmentid=23788&d=1121269005 to set band selection to 900/1800 (still no service)
3) I removed sim card and did a hard reset followed by soft reset. I put a sim card back and soft reset BA.
--- I guess at this point it's 2003 with 900/1800 band and working
4) I upgraded my ROM to 6.5 and it is working now.
the link is dead.sorry for my bad english i've tried all the procedure but still had no gsm on my xda iis dont have imei and i cant see my radio version can you help me....
Lucky You that I still have troubleshooting tutorial in my file archive. I've written it by myself when was unlocking many of these devices.
Although I'm not sure if it will help with symptoms You listed...
Here it is what you can try to do if your Blueangel PDA phone constantly showing "No Carrier" and it is not possible to enter phone settings:
1. Take off the battery from the phone while it is turned on.
2. Place the battery back in, turn on the phone. At bootup there should be stated "NONE" instead of versions of "R" and "G" (seems that it is required to be so).
3. After OS had boot, run the Unlocker. Few times, maybe.
4. Reboot.

Help pls! Can't USPL or upgrade radio or rom anymore

Hi,I have an xda orbit (O2 uk) and I ran the USPL super CID on it which went thru fine. I then did an OS upgrade from the official O2 website to WM6. However my phone wouldnt make calls or accept calls. The signal bars were initially low which made me suspect the radio not being optimum. Tried to upgrade the radio from 3.06.90 to 3.08 or 3.19 but it kept on giving an error 270 - file corruption,tried flashing to another rom and still the same error.I then tried to re -USPL it and even that wont take... Can someone please help me out with this as I am at my wits end to a solution...Thanx a lot
still sweating....
ok...update so far...repeated the flash over and over again, Hard reset and moved the enable and cert rapi to the xda and ran them there first after taking out the sd card. finally it took after a few more atempts. I then ran artemis 20273 rom which flashed easily....HOWEVER even though the signal bars are still up I cant call out or receive calls. Dialling out ,the call disconnects immediately even before it rings (like 0.5secs after i hit the send key). If I call the phone I get a message that calls are not currently being connected to that number! (i know the sim cards working as its my main number) Anyways run uspl again and flash radio to 3.18...goes thru easily but still no calls in and out. Is there anyone with an idea as to the problem or solution.

"No service" error after trying to update!

Okay so I just tried updating manually to Pie using the zip file from this thread: https://forum.xda-developers.com/zenfone-5z/how-to/zs620kl-fota-update-links-update-20-08-t3831794
Here's where the problem starts. I placed the zip file into my internal storage and rebooted. Sure enough, I got the update message but when I clicked it, it said: "System update failed".
From this point onwards, my phone shows "no service" even when it is able to detect the SIM card. I've put the SIM card in another phone, and it works without any problems. I find this weird because if the update failed, why did it affect the network connectivity?
I tried the following, to no avail:
turning on and back off airplane mode
factory reset
in mobile network settings, I tried manually selecting the network. When I try, it says "No networks found"
dialling *#*#4636#*#* -> Phone information -> "Mobile Radio Power" -> I tried to switch this on but whenever I leave the screen, it goes back off automatically
IMEI number exists. No problems here.
So I used a suggestion from the comments and wiped data and cache from FOTA Service and System Updater, and tried the update. It worked. I'm now on Android 9, still with "no service" error.
I've been trying suggestions all day and it's leading me nowhere. Really frustrating. I'd be thankful if someone can offer some helpful suggestions.
EDIT: It turned out to be a hardware issue. What are the odds? Maybe the software update caused it, idk. Repair guy said something was loose inside, he fixed it within 10 mins. If you guys face the same problem, get it checked with your local Asus authorized service center. Warranty covers everything.
Download the update for asus's website it's about 1.65gb. it would work
You mean the latest Pie update? On the website, it's for Taiwan SKU only. It won't work.

Yes, I was able to upgrade to the Android 9 ROM. That's not the problem. My problem is having no network connectivity whatsoever. As I said, "no service". Persists even after downgrade. I think it might be a hardware issue.

Please read everything properly. Please. The link I shared has two guides separately- one for rooting and one for downgrading. You can downgrade without rooting. Also, the link you provided is strictly upgrading only. Stop wasting everyone's time.
Hi...
I had the same issue 2 times!
First one was after an update, my phone restarted, then "no service" after that! I tried to downgrade, tried to reset it, and no service...
So i sent my phone to Asus authorized service center, they changed the SUB PBA...
I works for exact 30 days and, after a restart becouse the system crashed, it has no network again1
so i sent it to serce center again today...
I updated to Pie on 28-Jan it was stable for 4 days on 3rd feb. It is showing 'no service' i reset the phone but no use. Any please help......

If you've exhausted all your options software-wise, then it's probably a hardware issue. Check it out with an Asus service centre.
Hello everyone! I figured out the issue and the solution to the dreaded no network/no SIM card issue for the ZenFone 5Z. It is not a software problem. It is a hardware problem indeed. The new firmware basically lets the SIM card slot "work properly". If the SIM slot of your phone is defective, this issue will trigger after Pie update.
Why it is happening:
Take a look at the image below (courtesy FCCID.io)
There is a switch (highlighted in red) which "tells" the phone whether a SIM is inserted. When the switch is closed, it means no SIM card is installed. When the switch is opened, it means SIM card is installed. If you insert the SIM tray, it will allow one of the metal to lose contact with the other hence telling the phone to operate SIM signals.
If the top metal cover is pushed down and touches the switch, this SIM enable signal will malfunction causing the issue you all are facing.

The solution:
You will need: A SIM ejector tool for removal of the SIM tray, a flashlight and a precision knife (I used a surgical knife since it is thin and rigid and works perfect).
Turn on the flashlight and look at the SIM slot from the side. You will be able to see the switch terminals I am talking about from a different angle. It will be the farthest terminals just a little bit to the left from the mid point. Insert the knife and tilt it very gently keeping your hands steady such that the top metal lifts slightly from the switch contacts. If careful, you will hear a click. Insert SIM and install SIM tray. Cross your fingers and behold! You will get network. I am fairly certain this is going to solve your issue. So if your phone is out of warranty or you don't want to avail warranty for such a silly issue, give this a shot and post whether it worked for you.
