Q. My wife has an Optus (Australian) F1f, which we had unlocked but it appears that Optus disabled some bands in their version of the device. This has become a problem now that we are using another carrier. I'm hoping these were disabled at the Rom end and not hardware.
Will shifting to another ROM like Spectrum give access back to the full range of bands? I tried flashing the official Oppo ROM from their website using standard recovery but it appears to still be Optus with all the bloatware that usually comes with. I was hoping it would install a generic firmware but it didn't.

I'm running the KitKat+ ROM I found in the development section plus faux kernel, I flashed over jellybean and applied fix v2 so I'm getting no problems uninstalling apps or entering security settings. Thing is when I'm at home or even outside I get really slow network speeds of about 0.4 Mbps down,and in settings-aboutphone-status it switches between hspa and hspa+,but down the road about 350 metres at my kids school I get up to 7 Mbps down,I'm just wondering what version of the moto g is this KitKat+ rom based on,I own the UK retail version and was thinking if its based on a us version would it cause problems with connecting to a UK network or have problems with hspa+ in the UK based on what base this ROM is using,just throwing it out there.
Have you tried setting it to GSM auto (PRL) ?
My previous phone (HTC One X+) was running BlackBean rom and was set to CDMA by default, meant that i had to reset to GSM after every reboot.
I have experienced this also on a UK XT1032 running US Global GSM 4.4.2 - Data works but often slowly and stops entirely for periods of time. I had assumed it was the ROM and I'm waiting for the UK 4.4.2 stock firmware image which I expect will solve it. Perhaps unrelated, but I've noticed Opera Mini will not work over 3G in this ROM, but it works fine on Wifi.
EDIT: I was just thinking; that by fastboot flashing the Stock US firmware image, the UK modem firmware may also have been replaced. That could explain the problems. Flashing back the 4.4.2 UK modem firmware might fix it.
My Baseband version:
MSM8626BP_1032.340.63.00R
Can someone with a US Global GSM XT1032 confirm their Baseband version? Nevermind, confirmed via google. UK Tesco XT1032 running 4.4.2 also has the same Baseband version.
You could try flashing the UK stock 4.4.2 'NON-HLOS.bin' which appears to include the modem firmware. However if I remember correctly, flashing an incorrect radio firmware is one of the few ways to irrecoverably brick a handset.
Safest bet is to wait for the full UK stock 4.4.2 firmware image and fastboot flash that. In future when you flash a different ROM, i.e CM11, you are likely to use CWM/TWRP and the existing UK modem / radio firmware will remain untouched.
If someone wants to correct me on this, please do.
Hello, just upgraded from a Galaxy S4 on T-Mobile to an unlocked Verizon HTC One M8 handset. Popped in the sim, I can send and receive text, data on HSPA/3G mode but not one LTE or Global mode (anyone know why this is? I'd like to be able to use t-mobiles LTE and not just HSPA/3G), get the usual "sim unknown source" stuff. I am wanting to flash Skydragon.
My question, is there anything special I need to do before/after I flash these, since I'm using a different network than what the handset was originally supposed to be on? Maybe I need to flash different radio? This is my first time using an unlocked phone, previously all my phones with custom ROMs were on the same network as the handset variant.
Otherwise, would I just update to the latest 5.0.1 OTA update from Verizon, root/unlock bootloader, install TWRP, then flash Skydragon, and I'm all good?
Edit: Well, further reading seems to indicate to me that it turns out verizon M8 devices already updated to 5.0.x are still not able to be rooted at this time?
Thanks for the help
Sir I purchased a new unlocked S6 Edge ( 925A) at&t device from abroad to use in india.
The guy told it's fully unlocked and it support any sim card. Buy when I checked with Indian Sims I am getting only 2g signals .. I am not getting 3G and 4g signals..
When I checked for network selection mode settings it's missing in the settings.
No software OTA update is available. . I think it's also disabled.. when I checked the device status it is in "custom"..
So if I flash a stock ROM with Odin will it lock again ?
Do I need to unlock it again.. ??
First check the model from bootloader, if its actually a att variant then you can flash a stock rom too make it work as normal, but if its some other variant then get back to this thread again.
Its surely an at&t Variant of Samsung Galaxy S6 EDGE.. its model number is 925A.. which is only available for ATT..
Its baseband version is G925AUCU1AOCE
I purchased this phone as fully unlocked from UAE but in india when i start to use it i came to know that its not taking 3G and 4G signals .. but 2g Signal and Data services are working fine..
I got the phone in rooted condition without any Boot animation of At&t. Since its rooted i am not getting any official updates.
I am also facing many software bugs.. from different apps..
So really want to flash the phone with a new stock rom for using it..
I have some doubts about it please clear it..
1) if i flash it with an official att stock rom will it lock again for att network ?
2) can i remove the att boot animation after flashing with stock rom ?
Sent from my SM-925A using XDA Free mobile app
Providers in India use bands 3, 40, and 41 for LTE. The AT&T S6 Edge is only compatible with band 3.
I doubt you'd be able to flash a different ROM, and even if you could, you still wouldn't have compatibility with bands 40 or 41.
Firstly Thanks for your reply.. i know that S6 Edge at&t only support Band 3 LTE cuz it's a FDD LTE supported device.. in my country here providers are using both TDD & FDD LTE bands for LTE..
In my region "Kerala" at presently all the providers are using Band 3 which is compatible will my phone. But i am not receiving any LTE and 3G signals..
My friends have different unlocked phones from T-Mobile they are not facing any problem..
I am still doubt the flashing ROM.. i am going to flash the stock rom for at&t.. it's the only official rom available for my device.
It could be an APN issue. Make sure the settings are the same as your friends are using. Beyond that, I have no idea.
Nothing Wrong with the APN.. cuz i am using 2G data without any problems.
We have same APN for all 2G ,3G & 4G..
I think its the problem with my software..
I can't switch between LTE/WCDMA/2G because that network mode selection option is disabled or not available..
I am compelled to flash a new Rom..
I don't have any other options.
I own a good phone but i can't use it . Really sad about it..
for sure people here can help you more on this

I bought 2nd SK Telecom unit (930S), which has same SoC as 930F. Is it possible to flash 930F modem to 930S? I get this issues regarding mobile network in LTE doesn't work well, I have to lock it to WCDMA in order to make network run again. I suspect this as modem issues, but is it? Or is this OS problem? Tried 3 carriers, problem persists.
While they are the same SoC, there are some differences that will make flashing G930F over G930S result in bootlooping.
I assume you're not in South Korea?
The firmware will be configuring for Korean carrier / networks. Your best bet would be flashing TWRP, then using this to change your device to your carriers CSC https://forum.xda-developers.com/s7-edge/development/utility-flashable-csc-selection-30-t3392957

It could be the stock ROM on there (with sk apps). When I bought mine I immediately flashed TWRP, NAND backup and flashed a custom TW ROM and had zero network issues. I never bothered seeing if the stock ROM was worth using. I'm using BlackPearl with zero problems with network or otherwise on AT&T.
I should clarify many custom ROM's work on goth 930F and 930S, but stock 930F images will bootloop a 930S.
hello, im using g930s too with g930s stock bootloader and baseband/modem. but with hyper alvi 4.1 rom. still got problem in 4G mobile network signal. should i try to change csc or modem file? i think the csc was from wrong country, could that be the culprit? thanks guys
Hey everyone!
So, I own a LE2115 OP9 5G and it is currently operating stock OOS 12, I have no issues with it, I've run multiple custom ROM and have rooted it from the beginning. My issue is this:
I currently use Metro by T-Mobile as a carrier, I wanted to switch carriers and as it is network unlocked from the factory, I assumed that it would be good to go as far as switching it to a Sprint/T-Mobile acct. Apparently, they "Sprint" is having some sort of issue activating the SIM because it is international FW. Could I possibly change my FW variant to T-Mobile and solve the issue? If so, can I do that using an MSM tool? If anyone has the solution, I'd really like to be instructed how to fix this. I love the device, and it's just strange that I cant get it to work even though Sprint and T-Movile and Metro by T-Mobile should all be the same. Thanks in advance!
