[Q] Help, SGS has no signal sometimes

My phone is from UK orange. my phone has great signal at home and office.
However, after I upgraded to Froyo JPO version firmware, my phone has signal in my office with 3G but has no signal at home and some other places where the 3g signal is weak or not working. This is very annoying. Please anyone can help me?
My original firmware: JP5/JP3/JP1
My current firmware: XXJPO/XXJPP/XAJPO
MY Production code: I9000HKDORA
Tonight I try to flash lots of versions from samfirmware.com but there is no signal for all firmwares.
Please can anyone help me? It seems that my current wersion does not support 2G signal???
Thanks in advance

can you check your IMEI in the phone (settings>about phone>status) and compare it with the IMEI indicated in the box (or remove teh battery and there should be a sticker at the back of teh phone with your IMEI).
Note: Also check if your APN settings are correct and complete. It might have been deleted or changed after the flash.

I have checked the imei, it is the same. The apn is orangeinternet, I think it is correct.
When I go to somewhere, the phone can be used with symbol of 3g or E or H, but at home only signal bar shown and emergency call only.

In Settings / Wireless and network / Mobile network settings / Network mode, set to GSM/WCDMA (auto mode) and see what happens

It is GSM/WCDMA (auto mode) selected.
I remember I can only choose 3G and wireless network when I just flash the FROYO JPO firmware...

It is possible that orange are working on the network. I had similar issues a few weeks ago (I'm in the southeast) bit is now fine. You could go see your local orange guys and ask.

But I can use this sim card on the other phone, like HTC HD2, perfectly at home. Does the SGS have such bug? I am in the southwest.

try see if you have the missing 850 band bug?

Anyone knows where to download the orange customed firmware: I9000BVJM5/BVJM1/RAJM3?
Thank you!

Not getting 3G :(

Hello,
I live in a country where 3G is in 2100 Mhz band. I bought the phone unlocked but it is still showing only E even after enter the operator's 3G APN.
I am not able to use the *#*#4636#*#* code OR able to choose the network. It is greyed out.
What should I do?!
Thanks.

That 4636 menu is disabled on the Atrix HD, download the app Phone Info from the market. It will allow you to access the menu and change the network settings.

Its disable on the AT&T Atrix Hd just like on my Atrix 2 AT&T before. But for the Bell Atrix hd we can access the menu and we can change the network settings. Look for the app NETWORK from playstore but im not sure if you can change the network settings.

I'm not sure if this will work with you, but I have an unlocked Bell Atrix HD on AT&T and I had similar problems at first. I was not getting any LTE even though there is LTE in my area.
I went to the AT&T store to tell them, this is what happened: When I first went there to get a micro SIM card (I had a regular SIM), they activated a new card, and put my AHD's IMEI number on my account. This allowed my phone to text, make phone calls, and connect to HSPA+, but no LTE. Well, since this phone is an unlocked version from another carrier, the IMEI number is not recognized by AT&T. So, the system didn't know that I had an LTE phone. So what they had to do was get a real IMEI number from an AHD that they had in the store, change the last number, and apply it to my account. This then activated the 4G LTE data plan for my phone.
I would try this.

C5502 LTE option in phone settings

Why does the C5502 offer LTE as an option in the mobile network settings?
Can others confirm this is the case with their phones?
Is this just because firmware is common to both or have I got a mislabelled C5503?
We don't have LTE here so can't test.

Either you are lucky to get a C5503 model out of the box (of a C5502) or the firmware that is currently installed in your phone is for a C5503

Hmmm, model number on phone and in settings says C5502. My wife's C5502 also has the LTE option. Both bought brand new. I imagine it's just a common firmware and there's no way to enable LTE. In service menu the "working bands" only list UMTS bands but LTE is presented as an option in 4636 menu.
Is there a software way to check the radio chip on my phone?

[Q] No 3G on unlocked Sprint HTC one M8 in Spain

I have a HTC One M8 sprint that i bought on Ebay, i have no problem to make and receive calls after i unlocked it but there is no mobile internet.
My APN Settings is correct, however i only have the option of bearer: LTE or eHRPD or Unspecified
When i search for networks on my normal phone i always get two options:
Movistar 2G
Movistar 3G
Vodafone 2G
Vodafone 3G
and the other networks here.
On the HTC that i sim unlocked i only get:
Movistar
Vodafone
Orange
There is no indication on if it is 2G or 3G.
*#*#4636#*#*
Have set it at GSM Auto PRL and restarted the phone, i have also tried all other network types without success.
Under Phone Info i get Current Network Movistar
GPRS Disconnected (Cant seem to activate that)
GSM: In Service
Network Type: Unknown
I have tried different radios, but no one has worked and they all end up with the phone entering a loop where it restarts and cant recognice the SIM card.
Mobile Network Settings:
Network mode: GSM/UMTS Only
Allow GSM Data: Ticked the box
Is there anyone who has been in the same situation and who has found a solution?
I have seen a number of posts where people say that they cant get data but calls is working, but the only resolution that people has offered is to set the GSM Auto PRL and restart the phone, that has not worked for me.
Very happy for any help that you can give!
Thanks

I am having same issue
Any solutions yet ?

Have you tried setting a GSM band from the top menu of *#*#4636#*#*?

You mean by changing bro wcdma prefered or gsm pro ?
Yes everything

Use QPST tool and allow all 3G networks to work. It unlocks all 3G networks. You are not getting UMTS signal because Sprint by default has unlocked only US 3G band (I think 1800). Hence, you need to unlock all 3G networks

[Q] Help understanding 4G vs LTE designation

A few days ago, my wife and I both got new Sony Xperia Z3 Compacts. We both activated on Cricket. Everything seems to be working well, but one of the phones shows it is connected to 4G and the other shows it is connected to LTE. Both phones have identical APN settings. Additionally, they have different options for 'preferred network type'. They one that shows LTE can choose
WCDMA only
GSM only
WCDMA (preferred)/GSM
LTE (preferred)/WCDMA/GSM.
The one that shows 4G can choose
4G (preferred)/3G/2G
3G only
3G (preferred)/2G
Can anyone shed some light on why they are showing up differently?

It seems that u have different types of z3c. Maybe one is with another region firmware.
Hit *#*#7378423#*#* on dialer and check under Service info - Software info if the customization version matches. If not, one phone has another region firmware. There is no difference, only that it shows 4g instead of lte and thats the same

Thanks for replying!
They are both D5803, but yes, the customization version on the two are different. The LTE one says 1289-4696_R4C and the 4G one says 1288-6117_R7C. Is there a way to get them the same?

U can use xperiafirm to download the r4c firmware and flash it via flashtool. Make backup of internal memory or uncheck userdata in wipe options or memory will be erased
