[Q] MZ602 4G/LTE on different carrier - Xoom Q&A, Help & Troubleshooting

Is it possible?
I've tried to flash my device with the CDMAWorkshop 2.7 but there are no EVDO tab and some other features. I can't find any newer version with full functionality. like 3.6 or 3.8. Demo versions can not write PRL's and EVDO/CDMA settings.
qpst 2.6.366 can't flash this modem too. Is there any way to downgrade CDMA firmware without any brick?

[Q] Xoom on wrong baseband

I changed the baseband of my Xoom from GSM/UMTS to USA by a mistake.
No Idea how to reset this to european settings.
The mistake happened using the app "Netzwerk" by Phillipp Mangelow.
Since then there is no chance to get an internet connection.
All settings i can directly access are ok.
The above named app has an error and offers only "USA" as selection of baseband.
Has anyone an idea how to reset this or knows an app which modifies this setting?
Xoom without radio is not even a half xoom
Kind regards,
Willy
Try tiamat new rom, there is a possibility to change it back to EURO mode
Hi,
i use a international version of motorola xoom mz601 in india and have updated to android 3.1 and use the latest baseband n_01.83.35p.
after this update the band changed to USA band 800Mhz? i cannot use any network 2G or 3G and the motorola doesn't show any network operators.
i really want to revert back the settings.now how can i downgrade my baseband and what commands i need to execute also i have tried moving to stock 3.0.1 but no change in baseband.
any apk file that would help me change the band?
thank you.
Please help
If you are rooted, and if you have a previous backup done thru recovery before, just go to recovery, advanced restore and restore system only. It should bring back your baseband.

What I did was go back to a stock 3.1 provider firmware. Being in India I used Original rom. I flashed boot, system, data and recovery. At that point the 3g radio still wont work, Let it do the OTA updates to bring it to 3.2.2 and it will start working, I think one of the OTA updates flashes the modem and or bootloader and resets it to the correct band.
I could then go back to a custom rom and it was all good, I make sure I stay away form the band settings in future.

[Q] VZW 4.04 Radio flashing

After flashing the newest Verizon radios, I can no longer access the 'more' settings under wireless and networks. I did first revert to the 4.02 radio and bootloader before flashing the newest ones, and am suffering from no other issues. Thanks for the help!

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.

Help needed for CDMA data service (downgrading from 4.4.2 to lower version)

I have a Samsung Galaxy S3 SCH-I535 CDMA Verizon & GSM phone. Originally it was on android 4.1.2 and working fine for both CDMA and GSM (one at a time). CDMA EVDO Rev A data service was working fine.
I am using this phone in Nepal (not in USA). It was carrier unlocked for both CDMA & GSM when I purchased from Amazon. (so, I guess, Originally it may had some customized firmware/ROM for International use, I don’t have much idea).
I was asked for firmware upgrade every time when I run Samsung Kies. One day I clicked to upgrade the firmware. The upgrade was over successfully. But the new android version I found on my phone was 4.4.2.
In this version /new upgrade, I was unable to use CDMA data (EVDO-rev A). So I wanted to reverse back to old version. I search the process in Google and tried to load firmware with the help of Odin3 using this file:- “I535VRBMF1_I535VZWBMF1_VZW.zip”, but it was not successful. Result: Fail(Auth)
Then I loaded firmware for 4.4.2 using Odin3.09 (AP: “I535VRUDNE1_I535VZWDNE1_I535VRUDNE1_HOME.tar.md5”) and now the phone is working.
• If I use GSM SIM I can make call and use HSPA data service as well by adding new APN.
• If I use CDMA RUIM I can make call, BUT DATA SEVRICE using CDMA EVDO Rev A is NOT WORKING!! (I can not save APN in this case).
Now my issue is how to make CDMA EVDO data service working in my phone, because my basic requirement is to use this phone for CDMA service (voice + data).
I can edit the APN but when I click “Save”, nothing was saved. So I can not select APN for my carrier. I tried using APN Manager Pro too, here I can enter & enable the APN, but did not work. The phone is not able to dial the data access code #777 (verified from CDMA service provider side trace).
Can someone help me what I should do to make my phone working for CDMA data. My phone is rooted.
I guess it may work for CDMA data if I downgrade it to 4.3 or 4.1.2,
Can I do that. If so what are the procedures / steps. Any help in this regard would be highly appreciable.
My data worked this way

I think your problem is the region is not set Nepal...I installed dark jb rom in my phone and data was gone since then. Then I manually downloaded stock firmware and flashed through odin but still data wasnt working,nd while in recovery mode i saw region INS ie India. then something came in my mind and.. .I changed it to NPL and now i can use data in only sim 1 only not in both sims. So i also may need some help.
For you *#272*IMEI# . Use your phones IMEI number there (*#06#) . Select NPL region.
NOTE: It will hard format your phone installing required carrier apps, aps, bla bla and hope work on your phone

I found that the hidden menu (& hence secret code dialing) was disabled in my phone. Following guides from Google search I enabled it. Now codes likes "*#06#",*#1111#", "*#0228#" etc are working, but "*#272*IMEI#" is not working. Any idea, why it is not working?

Well, it looks to me as though you've locked your bootloader and are now stuck on 4.4.2. For some reason, Verizon forces Samsung to lock their bootloaders, which means we (the consumers) cannot install "custom" firmware on our devices (or downgrade).
Once you're on 4.4.2 NE1 your stuck with it. No downgrade possible at least not without a Jtag service

930F modem for 930S

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
