[Q] - General Questions and Answers

Hi everybody,
I have been following XDA for years now and have always been able to find answers to my questions here regarding flashing for a HTC Desire, Galaxy SII or my current Galaxy S4 I9505, rooted running a 4.3 GPE rom. Baseband is XXUDMB. Recovery is CWM 6.0.4.4.
After following the thread GOOGLE EDITION 4.4.2 by Danvdh, Kryten2k35 & Ktoonsez I decided to flash. Love this rom, it's superfast!!! One thing didn't work for me: the phone kept losing connection with my Dutch mobile carrier Vodafone (no data, phone calls not possible), especially after locking the screen. To my understanding the rom does not ship with LTE of GSM modems, so it should not be the problem that a 4.4 LTE modem causes sound, data or WiFi problems when on the "old" bootloader (pre KNOX). After flashing the baseband still shows XXUDMB.
I tried *#*#4636#*#* and setting network type to GSM. However, the menu is not the same as my current 4.3 and the option LTE/GSM auto (PRL) is not available.
Reverted back to my 4.3 rom for now, but really hope somebody knows how to solve the issue.

[Q] 3g issues after upgrading gt-i5500

Hi everyone
Here in Argentina, after upgrading the phone to froyo, with official and mod firmwares (motafoca), a lot of people experience the lost of 3g network, the phone only works on edge. we already checked the apn, did the herware reset, vn rebuild and all the obvious solutions.
Im thinking the problem is the "amss" file in the new firmware which is the qualcom modem configuration.
Someone know if its possible to backup it or maybe delete from the firmware before update it with odin (having a working 3g phone)? Thanks

[Q] Used Select radio band on Razr HD Maxx, now will not work in the UK

I'd been using my Razr HD Maxx xt926 in the UK on the stock ROM 4.1.2 but could not get WiFi hotspot working as it called back to Verizon and told me I was not subscribed.
I unlocked the boot loader, installed TWRP did a backup then flashed with LiquidSmooth 4.2.2 all good so far but could not connect to the cell network and make calls or data. Then I found the *#*#4636#*#* and Select radio band menu... in the LiquidSmooth ROM there are various bands to choose from non or which worked and no European Band. I restored my Standard ROM where the Radio was working then I took a look at *#*#4636#*#* and Select radio band menu and choose USA Band. This turned out to be a bad idea as now I cannot get the radio to work, all Im seeing is the signal meter with a red no entry symbol on it.
Since then I've tried: Wiping / Formatting use TWRP, Going back to LiquidSmooth, Eclipse 1.3, CM 10.1 and various fiddling with the Networks options in setting and this (but its for the US) http://forum.xda-developers.com/showthread.php?t=2166542
Any help much appreciated as the only other options I've read about are walking in to a Versizon shop where they can flash it back to standard, but I cannot do that being in London :s

[Q] Galaxy S3 (GT-I9300) No Service on HSDPA Mode / IMEI lost After Flashing

Hello,
I am Ankit from INDIA.To cut the long story short i just flashed my Galaxy S3 to come back to official 4.1.2.

Then i downloaded new firmware from sammobile.com.Now got everything back IMEI is correct have network but am unable to get HSDPA network.phone is working well in GSM Mode but as soon as i chooses HSDPA gets same problem of No Service.

what's causing slow network speeds?

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.

[Completed] AT&T LTE signal issue, Cyanogenmod 11 build cm-11-20150111-NIGHTLY-m4

I would have rather posted this in the forum thread for Cyanogen 11 for the m4, but I cannot post there.
HTC One Mini (m4) had AT&T stock software (Android 4.?) with Sense 5. I installed the latest stable Cyanogen 10.2 build using TWRP. I decided to use a different phone so I didn't try anything after installing 10.2. So RUU flashed "RUU_M4_UL_K44_SENSE60_MR_Cingular_US_4.13.502.3_Radio_1.29.40g.00.19_10.32.40.1115L_release_385202_signed_with_hboot" (which is AT&T Stock Android 4.4.2). I also installed an AT&T Sense 6 update and relocked the bootloader. Later, I decided to use the Mini. So I unlocked the bootloader again (which wipes all user data), and installed TWRP recovery again. I did a factory reset from TWRP, and cleared the cache and dalvik. I installed Cyanogen cm-11-20150111-NIGHTLY-m4. I wiped the cache and dalvik again for good measure. I then installed the google apps for KitKat. The install went perfectly and I have not had ANY issues with the ROM at all, save one.
There is an AT&T LTE tower right off the exit ramp where I work. I attempted to toggle on LTE using the quick settings in the status bar. The toggle remains on, but I cannot receive LTE signal. In Settings -> Mobile networks, I am unable to select "LTE (preferred)" unless I first put the phone in airplane mode. LTE will remain checked, but I observed when I am near that LTE tower, the setting reverts to "3G". If I enter phone setup via *#*#4636*#*#, i cannot make any setting other than WCDMA preferred unless I turn off the radio. Again, when i get near the tower, the setting will revert to WCDMA only. THe Advance Signal Status app shows n/a for everything under LTE (4G) Signal Info.
I installed the ROM without a simcard. I'm on an LTE-enabled plan. Another stock device on my plan can receive LTE. I've set up my APN to the letter per AT&T's website. I even added fota like the stock rom had (even tho i'll never be doing fota updates w/ a custom ROM).
I've read on the net it may be a bad sim card, but i had the same problem on an LG Nitro running cm 11 latest nightly (brand new LTE enabled sim). I've also read that maybe AT&T has to specifically input my phone's IMEI for LTE to work (this was my wife's company phone before tho; i'm sure the IMEI was in the system). Anyhow place greater weight to the words of XDA over other sites.
Could this be some type of baseband issue?
Hi,
You will need to register on XDA and ask for help in the thread you downloaded the rom from. Members under 10 posts can post, it will be directed automatically to the devices Q&A section, along will all other new members postings.
Rom issues should always be reported in rom threads. As well as reading the opening post for known issues, and the last several pages to see if your issue has been discussed.
Good luck!
