[Q] Help. Flashed my Telus Nexus S with ATT firmware, now network type shows GPRS.

I'm (obviously) a bit of a newb when it comes to android, and I was flashing back from cm7 to see how it was done. When I reinstalled GRJ22, everything was working fine. I then downloaded and flashed the OTA update to GRK39C (or so I thought). It turns out it was the update to GRK39F, which apparently is ATT or GPRS specific. My phone now thinks it's on ATT and is trying to use GPRS.
I'm on Telus in canada, and use HSPDA.
The phone was also showing baseband version I9020AXXKF1, it should be I9020AUCKD1.
I've tried restoring from a backup, flashing back to cm7 and to stock fw's, and even tried flashing the radio.
My phone still shows GPRS, and now baseband version shows I9020AXXKD1.
Is there any way to fix this? I hope someone here is knowledgeable about this...

That baseband is associated with the i9020t, or the t-mobile variant. The canadian nexus s is identical to the at&t version.
There is a sticky with all the roms. Use it and get the right rom installed

Unfortunately, the ROM I need seems to be one of the missing ones. Is there any way to backup the radio from my wife's (identical) phone and flash it to mine?

It looks like the file I need is 5282b5b3eb74.signed-sojua-ota-178324.5282b5b3.zip but I'm unable to locate a working link for the file. Can anyone tell me if this is correct and/or provide a live link?

Actually that particular one you want has broken tethering... This is a dump is the 2.3.4 with I9020AUCKD1 radio from my US import i9020a tested and working on SaskTel HSDPA+.
http://dl.dropbox.com/u/7812800/Stock-GRJ22-i9020A-unsigned.zip (will need to be flashed via CWM Recovery)

Thanks! I got it working by flashing the unsigned ROM in the sticky thread, and I'm running cyanogenmod 7.1 RC now. I'll keep the stock ROM on file just in case though...

Cool... I hope it works out well for you.
btw i got a rooted version of the stock 2.3.4 if you are interested as well.

So, for some reason flashing with your ROM set my phone to UMTS. Can someone refer me to a howto to backup a full ROM image from a phone, since my wife's is working fine and is on the right type of network.

Success: G900F rom on G900V S5

Hi!
First I want to thank the developers and Goldie and Hashcode. I could not thank us topics because I am newbie here.
My wife bought a Galaxy S5 of a person who did not disclose that it was the 900V version, and only possessed a few languages.
Tried my best to translate or to enable more languages​​, all without success.
I managed to do the following to resolve the problem, and it can serve other people from other languages ​​that are at hand with this device, since the installed rom (AllianceRom) has support for multiple languages​​. The phone now appears like a 900F.
1) I root with https://towelroot.com/ towelroot
2) I copied this file from AllianceRom to the microSD card. http://forum.xda-developers.com/showthread.php?t=2716535
3) I installed the following safestrap this post http://forum.xda-developers.com/showthread.php?t=2793891
4) I enabled a custom rom 1 using the default options.
5) I installed the rom usually at recovery.
6) I waited a few minutes, booted, and FINALLY got to choose the option Brazilian Portuguese.
caveats:
Do not know if it's bug or something the ROM installing a rom that is not the phone itself, but the device does not turn off. He gets the LED on the physical and lighted keys and switches itself off. I have to take off and put the battery back.
If I had to fix something, which will not do out of sheer laziness, would change the standard sizes of custom rom, because I never want to see the original rom from Verizon. The custom rom ended up with little virtual space.
Sorry for the english but blame Google Translator!

If you look at the alliance thread a lot of people are having problems installing on a rom slot I used the stock slot and no problems

I just read in step#4 that he put it on a rom slot I've read that people are having problems when they use a rom slot instead of the stock slot and thought that might help no clue? I was just suggesting that by installing it on the stock slot might fix the following problems.

Alright so I thought I would shed a little light on this. I saw this thread a few days ago and decided to test this for myself. I have a verizon version of the S5 and the 900f version of the rom installed fine in the stock rom slot. The only issue at first was the keyboard was chinese. I had to activate the English one and things were fine. All the customization stuff works. I've basically tested everything and have been using it constantly for a few days now. So it does work. I haven't tried any other 900f roms yet.

Yes!
My wife exchanged the Verizon Galaxy S5 black by a white version. This time I installed the rom slot: stock, and everything is working perfectly. :laugh::good:

I would like to thank you all, specially amonteiro, only a Brazilian would need insert Portuguese language inside a Verizon Galaxy S5.
I have successfully flash the rom at stock rom slot.

I have a stock T-MOBILE rom running on my g900V with no problems or patches. Even installed mobile odin

what version did flash

hey could you let me know how you did this? did you flash the stock rom via odin? Did it not fail when trying to write the aboot? im trying to get ANY stock rom whether it be G900A/I/T/F onto my G900P

bug??
I think it's the the phones themselves. I have tried many custom roms and they all have worked but when I us a rom slot that isn't stock my g900v won't shut off either and I have to take the battery out. I even put a non rooted rom on every rom slot and none would shutoff other than stock slot.

G900TUVU1DOB1 ROM on G900V
I switched to T-Mobile from Verizon a couple months ago and kept my G900V to use on the T-Mobile network. I kept having apn issues with the Verizon (KK and 5.0) based rom and decided to flash in recovery the Beanstown 4.4.2 G900T rom and had great success . If you want KK I can confirm that both Beanstown 4.4.2 G900T and G900F roms work on the G900V kernal if installed on recovery (wipe everything first). I now am using [ROM]ViSiON-X US TMO[Android L 5.0][G900TUVU1DOB1][02-18-15] rom flashed by the installation method for the Verizon Lollipop to Keep Root. Steps are full wipe in recovery, flash rom in recovery (CANNOT, I REPEAT CANNOT HAVE AROMA), flash Verizon OA8 5.0 with Odin, boot 10 min wait... I believe any stock lollipop rom can be flashed, probably anything without Aroma... I have working Wifi-Calling feature, working Volte, everything works but no Wanam yet bummer...

This is excellent.
Question: Were you on 4.4.4 when you installed AllianceROM?, because it now has the 5.0 version, so I am wondering if i should update to stock 5.0 first and then use your method?, or maybe on 5.0 the method won't work? (towelroot, safestrap)
Thanks
Update:
I went back to 4.4.4, rooted, flashed the rooted Lollipop, but now safestrap won't load because it's Kitkat safestrap, so I can't manage to flash Alliance, any solution?

Flash the 4.4.2 stock kernel in Odin. Safestrap only works on kk kernel, then flash back to 5.0. Same instructions used in the forum to upgrade to Verizon 5.0, you just need to switch back and forth with the Verizon version of kk and lollipop kernels through Odin to access Safestrap.
Edit: Flash the visionx tmobile rom, it's amazing.

It just need to be done with safestrap recovery (You can not use Odin)
As always make a full backup up of your current rom before flashing anything. Wipe the system, data and cache and flash away. I've flashed g900t, g900f and i think some g900a Roms work as well... Can't remember. You will probably have issues if you still have a Verizon Sim card. And yes, WiFi calling will be there

[Q] HELP NEEDED - No Service after installing AOSP ROM

Can someone please help me out with an issue I am having...?
I can't seem to get Service after installing an AOSP ROM. I have been messing around with this issue for several days now. When I install a 'NON AOSP' ROM such as 'the 'MOAR ROM' it works fine, but then I go to in recovery (Newest TWRP or Newest Philz Touch) and do all of the required 'Wipes' then Install an AOSP ROM like 'Fusion', 'PAC' or the most recent 'CM11 Nightly' and I do not get any Cellular Service (WiFi is fine) and I have been looking for answers for several days and I can't seem to find any.
Can someone please help me out and let me know what I need to do, or point me to the right direction?
Thanks in advance for any help and/or resources that anyone can provide me with. It will be greatly appreciated.
Phone:
Sprint Samsung Galaxy S5 NE5 (Rooted with Knox Tripped :crying

Same was happening to me on philz recovery . so I install trwp for sprint/Verizon . then I installed trwp manager from play store . I install the PAC ROM from in the app and let it wipe it self . and that did the trick at least for me. I have tried many ways like your self. Nothing work that's the only way I got it working. Hope that help.

I'll give it a shot and see what happens. Thanks for the tip...
Has anyone else had this problem? If so, can you post anything you did to get it working...
My Phone Thanks You...

Im having the same problem on both TW and AOSP. If I mess around with the connection settings I can get a signal but when I reboot its lost.
Ive tried both recoveries and its the same on both. Ive tried flashing modems but that did nothing
EDIT: Seems that any kernel that I flash breaks my phones signal, I need to test further to see what part of the kernel flash is causing this.

Whenever I download klte roms I had that problem. I could receive data and text, but I couldn't send any. I used Google voice until I flash kltespr roms. once I flashed the specific roms for our device it worked. Though I had to install ktoonez's version of twrp to get them to flash. That file can be found on the AICP thread.

I think you guys need to flash an APN package with klte roms. Kltespr roms should not have this problem, but if you run into it flashing the APN package shouldn;t hurt there either. Not sure if there is still an APN zip floating around, you may have to manually fix your APN.

It turns out that the custom kernel I was using broke the signal for some reason. Other than that, I had no problems as long as I flashed a kltespr rom. Klte roms worked for data if i used a virgin mobile apn, but there was no texting or calling.
I attached the flashable zip I used to get the virgin mobile apn. I would recommend flashing it right after you flash your rom.

having this same issue also..
i have tried several things.. going back to complete stock and working forward
no matter what i do i get no service on any AOSP rom.. im going to try this apn fix. hopefully it doesnt further break anything lol

Anyone figure this out yet? I've tried about 4 aosp roms and no luck.

PacMan rom with PA Gapps and Ktoonsez kernel worked for me. None of the others did so it must be a ROM issue.

Part of the reason kltespr was de-unified was because of issues like this.
When I'd fix something it would break something else for T-mobile or international.
So I would recommend sticking to kltespr builds for the time being.
Hopefully some work I'll be putting in soon will help get this back in gear.

I couldn't get data on any kltespr builds except Pac Man and even then I lost data the next day for some reason. The new lollipop build has data working for me even though it's "GSM only" so just hoping it stays that way haha Waiting on fixes for battery drainage and I'll run it daily

Help Needed with Samsung G920P after root

Hi Guys, I know I am an idiot for not following all those guides properly and now I think I have bricked my device?
Well I am in Australia and I have this G920P model on android 5.1.1 (Unrooted). All was working fine, I bought it second hand from someone, I believe this is a U.S Sprint version, But I had my Telstra sim working in it with 4g data without issues.
So I decided to root it (without backing up- I know my mistake) and then flash XtreStoLite rom (again without doing any backup of original Rom). After that My device did not detect my sim card and there is nothing in the IMEI section of the phone.
I tried to flash official G920P rom via odin which installed successfully, and it shows signal on my phone, let me make calls but No Data. Seems like it is not registering my phone on the network properly.
So what have I done to my phone? Any chances to recover it somehow?

Ok, I have entered my network's pan settings manually and I get can get the data working but it only picks up 3g not 4g. I can make calls too.
But every time i restart the phone it keeps on checking the network status and picks up the signal after 3-4 minutes.
Also its stuck on the Hands Free activation screen and keeps on re-trying it.
Any help would be appreciated if I can get my device back to a normal one. Any other ROM's should i try?

One more question guys, Is there any non - sprint ROM for this device G920P? Because when I bought the device, I had no sprint stuff on it. No boot up splash screen or anything. I did not make note of which build version was it on but it definitely said G920P and it was on android 5.1.1.
Thanks

You may find and extra menu by typing ##scrtn#. I wouldnt reset to defaut as those general would be sprints settings. Try to find your carriers apn settings online.You should be able to cancel the hands free default activation. Are you still rooted?

I am now on a stock rooted rom. Would prefer to have a rooted rom. I have tried installing renegade but it get stuck on finding network and stuck in a loop.

G900PXXU1BOD3 rom, where can i find it?

Hi to everyone,
I have this unusual rom in my phone, as I have read through the internet, the XXU1 stands for a HongKong region.
The problem is, that there's nothing about such ROM on the internet, as if it never existed...
The phone was bought as new through online shop..
It has been unlocked through idoneapps. I use it in Europe. GSM and MOBILE data worked fine until I forced to update it through ODIN to G900PVPS3CPK1.
I was able to get the GSM to work, but the WCDMA network isn't available.. and the messages are split into pieces when I send them. As I've read, that is how they're sent in US.
I had tried many if not all of the roms, modems, kernels etc.. available in this SPRINT galaxy s5 thread..
but none gave me back the mobile network 4G.
So I was wondering if anyone has heard anything about such ROM (my original one) or where I could look for it? Maybe you have an idea what to do?

I searched for you. Here is the result.
https://samsung-firmware.org/download/Galaxy S5 (Snapdragon)/5998/ITV/G900FXXU1BOD3/G900FITV1BOD2/
This page explains it all.
I think you remembered a character wrong, it is an F, not a P. if it is really a P, and you are sure your device model is SM-G900P, then you must buy a new phone with a wrong ROM. I don't think that happens a lot. G900P never has a G900PXXU1BOD3 ROM. I think you flashed a WRONG ROM in the first place. DO NOT flash the ROM in this post until you confirm that your phone's Model Number(you can check this yourself in Settings, About device) is SM-G900F.

Thanks for your response. The sad thing is that the phone is G900P. I have attached the screenshot below. I have made a full TWRP recovery of the rom before doing any flashing. I am able to restore it all except the modem, as TWRP doesn't restore modems.
If I put a newer ROM bootloader and modem and restore the backup - I get a bootloop. If i put an older one I get no signal and the lower buttons arent working. Though I found BOG1 modem to work with my current firmware, but it's not fluent. The phone feels laggy and GPS isn't working...
So I am looking for a complete rom that could work in this phone without any recovery..

Can you find ok4?? Runs awesome for me, use Odin to flash it, you'll lose twrp but then Odin twrp

Sorry for the late reply, you didn't quote me, so I did not get the notification that you have replied.
It's very weird that your bought G900P with a G900F ROM. G900P doesn't support WCDMA network, I don't know if it's blocked by software. But the link in my last post indicates that your reseller flashed G900PXXU1BOD3 for you in order to make WCDMA work. I don't know if you can simply flash official G900PXXU1BOD3, because the system with your phone may be modified in the first place. If you simply want to restore original backup with modem, drop back to TWRP 3.0.2-1 or 3.0.2-0, 3.0.2-1 wouldn't mount external SD card so you have to move your backup to internal storage, I didn't test 3.0.2-0 but I assume it's the least buggy recovery for G900P so far.

If you simply want to restore original backup with modem, drop back to TWRP 3.0.2-1 or 3.0.2-0, 3.0.2-1 wouldn't mount external SD card so you have to move your backup to internal storage, I didn't test 3.0.2-0 but I assume it's the least buggy recovery for G900P so far.

My mistake,
I believe I had tried to restore backup with those versions of TWRP. They don't restore the modem part and give me an eror (can't remember exactly how it sounds), but as far as I have read, TWRP does not restore modem. It is impossible. So I can only flash it by ODIN, but there is no such G900PXXU1BOD3 modem on the internet..
I wonder, what if I would simply flash the G900FXXU1BOD3 or never rom with F symbol, could it work out for me? Maybe you have read about someone doing that? So far its my only hope...

I don't know if someone deliberately flash a stock G900F ROM to G900P, it would have most likely bricked the device. But I have noticed a slight difference between the 2 pictures you posted, first 1 says baseband version is G900PXXU1BOD3, idoneapps says it's G900PVPU3BOG1, I don't know which one is more accurate. I couldn't find a seperated modem file of G900FXXU1BOD3, yet there is a way to extract it yourself, simply change filename extension md5 to tar and open it with compression software. After flash modem, restore your backup.
Edit 1: Maybe you need to flash CSC also when you flash modem. But no rush, just try modem only first.

Hello,
Curiously I have the same problem, I bought the mobile by Ebay to a Hong Kong user and it comes rooted and with problems I do not know how to solve, from the beginning the camera did not focus until suddenly by magic, it focused.
Now I want to do a ROM restoration but I am not able to find that version since from what I see in the answers you have offered here seems to be "trick", have you found any solution? I would appreciate it if you told me so please.
Thank you.
A greeting.
