Hey fellow XDA'ers, I have a strange problem on my G920T that's been bugging me for a while. After flashing a custom ROM, my EFS was messed up. Thankfully I had backed it up prior to any custom ROMs. All works well n the phone except whenever it's rebooted it fails to register to T-Mobile's network. So I have to bring up the dialer, type in *#2263# and choose Band Selection, then LTE, then LTE All (which is already asterisked) and tap it again. Only then will it register on the network and then works fine. I've tried everything under the sun including restoring EFS backup, flashing back to stock, etc., to no avail.
I'm wondering if anyone knows of or can write a script that automatically runs the above process after reboot. I don't know enough to do so, and I'm not sure one exists. Not a vital request, more of an "I'm not going to be beaten by my phone" kind of thing. I'm willing to throw a $$ donation if someone were to write or provide a working script. Thanks!

Before you do that, is the custom ROM based on the same baseband your phone has?
Yes, the custom ROM is based on the same baseband - which is a great question. I’m using the stock rooted deodexed deKnoxed DOJ7 T-Mobile variant ROM with DOJ7 baseband. I’m DOJ7 across the board. This problem has persisted through multiple stock and custom ROMs. It seems to have started when I flashed the Back to N0t3 Note5 port to S6 ROM. I also get the Security Error: Your device has been flashed blah blah blah - but only when manually registering on the network.
I’ve been around the block as far as rooting and customizing my phone for a good while, and I’ve tried every trick I know to get this straightened out. SIM card works fine on my wife’s identical S6, so it’s not that. Short of hardware failure (which isn’t likely based on functionality when manually registered on network), something in some file was erased or corrupted and I can’t figure it out. Thanks for your question.

Ok, so I am somewhat new to the whole rooting and flashing of phones. I own the Samsung Galaxy Ace, from Koodo, and last night following a tutorial to install CWM4 and updating it to CWM5, followed by making a Nandroid backup and flashing Ice Cream Sunday Final, I had some issues.
The flashing went without any real problems, except one with installing CWM, but I sorted that out. I booted into the new ROM, and liked it, but after testing it I noticed it wouldn't load anything from my Koodo SIM card, like my contacts, and in the notifications bar where it shows your service carrier, it just showed a number. I was still able to send and receive calls and messages, but it was as if it didn't fully support my SIM. After finding a few things I didn't like with the ROM, I decided to use my Nandroid backup to restore, and after following a tutorial, I "successfully" restored the backup, according to Nandroid... But upon booting the phone, it was stuck on the boot logo.
After about an hour of searching, I was able to find out that CWM5 has issues restoring backups through Nandroid, and that I was screwed out of using my restore. I found the stock Koodo 2.3.4 ROM, and flashed it with Odin, and had to do a Recovery System Wipe to get out of a bootloop. I thought I was back to square one, and began installing my apps again and such with no issues.
---------EDIT---------
So, after hours of fooling around I replaced my save file with Root Explorer, like I was before, but then gave Terminal Emulator SU Permissions and used it to give the save file the right APP ID and Permissions, and it's working without freeze-ups now. I also used SQLite DB Editor to edit a fresh save on Where's My Water to reset my progress back to where I was before the update broke my save.
I am still wondering why my SIM Card didn't work properly in that ROM, and if there is a way I could make it work.
Is your model number GT-S5830D with baseband S5830DTLKI4? This is my model of the SGA and I've been reluctant to try flashing any ROMs because I can't find any success stories for this exact model. I'm also with Koodo and have concerns about how the SIM card will handle the custom ROMs too. If you do have this model, what has your experience been since your original post?
Winner Winner Chicken Dinner!

My model is GT-S5830D and I am on that baseband and have tried a few ROMs, all of which work. I would say try a ROM as the you should be fine, and you can always do a CWM Backup.
The SIM issues I was having has been resolved, as it is simply caused by being in Canada, and my carrier not being in the phones list, so it still displays a number, but all of my features (Calling, SMS, MMS, Data, etc) work fine.

Where is this tutorial??? I have yet to find one for the Koodo Ace that works.
Please bare with me since this is the first time having to post for an issue since I usually find an answer on your forums
So here's the situation.
I bought the photon q 4g lte from ebay and it came with the unlocked bootloader.
Needless to say it was with the stock ics and i tried to find a jellybean update because it wasn't taking the ota and ended up going with cyanogen since i had no problems before. However those phones i had before were with sim cards not cdma.
I found out i couldn't update prl or profile manually without having to do something on the pc.
So after searching left and right i found i could use rsl lite (I used 6.1.5) and eventually found the "stock" file from this post
http://forum.xda-developers.com/showthread.php?t=2095536&highlight=rsd+lite
I did the stock jellybean, got it to go through the process and it booted up with no errors.
However, when it boots into the os it pops up a force close on omadmclient_sprint_dataservice and eventually also on the process com.android.phone.
I tried putting it in airplane mode to see if the service error would go away but it didn't work for the process part crashing.
I tried re-flashing, deleting cache in recovery, doing a data/factory reset in recovery and the one time i was able to do a data factory reset within the settings menu.
I could not find anyone that said they had a rom that worked with sprint and updating prl within the rom, if anyone knows of one let me know and i will flash it through rsd.
Otherwise does anyone have an idea of what could be happening because googling the omadmclient part did not pull up anything specific and pulling up the process issue for other phones has not helped me either.
Was this a hacked GSM phone, or are you using it as CDMA?
I've never heard of people having FC issues after flashing a FXZ from RSD. Which one did you flash? Android 4.1.2 - Sprint US - 9.8.2Q-122_XT897_FFW-5 (No simlock) ?
If you are on stock, you should be able to update the PRL within the ROM.
I was trying to use it with cdma network through sprint. and yeah that was the file i downloaded, had to remove the getvar to get it working but flashed with no errors after doing that.
As for updating the prl i can barely navigate through the phone, there is no home page loading and the process pop comes up often enough that its hard to go through the settings

Sounds like something went wrong mate. Are you already activated on Sprint? I don't know if that would matter, it might.
I would honestly redownload and redo the RSD process.

I originally tried to activate the phone through cyanogen and then when the rep said he couldnt do it because of the lack of prl to update within the rom we just setup the activation back on the old phone/ That phone is working on the network.
I re-downloaded the file just in case and re-flashed but same problem. The only thing i thought of was maybe updating the radio but since its a stock rom it should work out of the gate. whats also weird is i tried turning wifi on but it didnt work either.
Anychange you know of a rom that works with sprint. I dont care if its stock since i would probably root later again.

Which one are you flashing?
Try another perhaps...? I honestly have never heard of this. It sounds like the phone might be damaged, or the RSD process just did not flash correctly.
I guess I should ask, was the phone modified at all for the GSM SIM slot mod? I wonder if having a non-Sprint SIM in is messing with it... That is just a shot in the dark.

so far the only rom i tried was 10.1 cyanogen and the stock rom for jellybean. However for the stock rom it doesnt let me downgrade to ics with rsd 6.1.5 do you think if i downloaded an old version i could downgrade to a lower stock rom?
Also I honestly had not looked for the cdma roms since most of what i saw was troubleshooting related for this phone but i just saw this rom -AOKP 4.2.2 (Android Open Kang Project) (CDMA&GSM) that you created - http://forum.xda-developers.com/showthread.php?t=2293892
I re-rooted and installed that one and it looks great, just wondered how you got sprint to activate the phone or if you had done it before changing the rom? Also how would the prl and profile be updated.
Lastly the wifi wasn't turning on this time either, it did work initially when i got the phone so that has me stumped.

To downgrade to ICS, you need to remove some additional lines. See this post for more information on that.
However, you should be able to update the PRL on either stock ROM.
I think I said this before, but I will say it again. You need to do PRL updates, activate the phone, and get EVERYTHING working on stock BEFORE you flash ANY custom ROM. This is just standard practice - you don't want to put the cart before the horse! Get the phone working, then play with custom ROM's.
Hello, this is my first post and also my first major problem with an android phone. I have been searching high and low on the internet for over a month now for an answer to my problem but apparently no one out there have experienced something similar. So, my story: I bought this thl t100s in march and it run without a glitch until i decided to root and try new roms. Used vroot without problems and flashed a newer version from needrom. This is when it went pear-shaped. After reboot I lost signal, invalid IMEI and nvram error. So I restored IMEI and fixed nvram but I never been able to regain network. Phone just couldn't connect to network. Not even "emergency call only". Reverted to stock, flashed about every rom and firmware I could find, installed twrp recovery, used mobile uncle, mtk tools, sn_writter tool, maui meta, nothing helped. The phone is searching for network but is never able to connect. Also, I tested quite a few sim cards that are working in other phones. So I'm assuming it is not a rom issue, but goes deep inside the android system, like the system cannot connect to the phone radio. I have no idea what to do next or if there is anything that can be done. I would really appreciate your help, any ideas or suggestions.
Thank you
Well playing with IMEI can be dangerous and should not be done. Though it seems like all you did was restored stock one. I'm guessing you can try restoring stock baseband. A search led me this thread of a user having similar problem- http://forum.xda-developers.com/showthread.php?t=2392203 The device is different but some solutions there are worth a try.
Cheers,

Thanks AJ, had a look at the post but samsung phones are a bit different from mtk based devices. I have checked my IMEI and is not blocked, as to phisical damage that's something I'll probably never know. I have successfully restored IMEI even tried some from my ancient back-up phones. no luck. Now baseband didn't seem to make any difference whether they came with the rom or I flush them separately. All I can think of is that there is a lost connection between the operating system and baseband and modem, like nvram is not being loaded/mounted by system. Slowly but surly I'm running out of options.
Well, @Perseus71 suggested that you should go back to complete stock and stock modem to get that working again. You can get further help here- http://forum.xda-developers.com/android/help

Hello all, I am new to this site and have a situation I could use some help with.
Last year I bought a new ATT SGH-I747 S3 in the US. I had it unlocked by T-Mobile and now use it in Ecuador.
Here are the facts;
ATT SGH-I747
Android Ver. 4.4.2
Base Band I747UCUFNE4
Kernel 3.4.0-1514807
[email protected] #1
This is the problem, I recently bought a Samsung Tab 4 to use for work. I intended to use the wifi-tethering between my S3 and Tab4. When I try to select hotspot I get a message saying "no data plan and or bad sim". Everything else works fine.
I went to my provider and they said the phone was broken!!? I went to a tech and he said that my provider is NOT in fact a 4G network as advertised and I would need a root to make it work. I have tried several apps to solve this but no luck.
I read that the CM11 Rom would correct this issue even in a NON rooted device, this led to several others issues; can't use Rom Manager on this device, can't make backup without root, I did finally find an app that would allow me to save my efs file but from there I have no idea what to do. If push came to shove I would lean towards rooting and using CM11, if it would solve the hotspot issue.
I have read several one click root, one click this, that posts but they seem to leave out some important pre root steps, like backup, efs file saving etc. At this point I am at data overload and could use someone who can give me the straight no B.S. this is what you need to do steps to resolve this. I am very good with electronics, but phones are not my forte.
Any assistance will be greatly appreciated.
Thanks,
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?

Have you the efs folder in your / partition? To check:
-Open any root explorer
-Go to / and check if efs folder exist
-If exists any file into it, tell me.

Thanks for a quick response, I Installed a root browser app and yes I can see EFS folder there and there are a bunch of folders and files in the EFS folder. e.g bluetooth, carrier, cpk, Factoryapp, imei, lost+found.... and so on
Appreciate your help in advance.

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?

Stock or custom? If i find it i'll give you a notice asap.
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.
Imei number is now showing up. But i wonder what version this phone was on when it was unrooted ? As everything was working perfect and i had no traces of sprint either.
