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

ok here goes, first off, i apologize if this is in any way redundant to someone's else question. with the amount of people whose phone got wrecked with the 2.3.6 update im sure somebody has had the problem im having.
like many people i just clicked "install" when google pushed the 2.3.6 ota. my phone was running 2.3.4. rooted. when it rebooted, i was greeted with the android exclamation mark.
i happened to have a clockwork backup so i tried restoring my backup. and restore it did, but not the radio. after the google update my radio was something like NO GSXXK1 or so. i tried the radio fix here:
http://forum.xda-developers.com/showthread.php?p=14564429&mode=linear#post14564429
i tried reflashing the stock 2.3.3 rom from google, wiping the bootloader and all. ive in fact tried many many things that ive read on xda and google forums.
now, ive managed somehow to have a running 2.3.4 with cell signal. using the efs file copy method in he link above. that restored my 3g and ability to place phone calls but sms arent working. i did the *#*#4636#*#* thing and notice that smsc is 00, i tried to set to the right value of +17057969300 for Rogers canada but all i get is an update error followed by a crash.
and now, funny, my search button is acting weird, like an eye that keeps twitching.
im not very knowledgeable in this stuff, just enough to get by and install custom roms but clearly im in over my head now.
why did copying my 3 efs file in the root of the sd card restore signal? i dont think these files really belong there, so just what the heck happened?
is there a way i can restore my nexus S to google stock rom when they shipped the phone? i mean, a complete wipe, sd, boot, radio...everything.
if i can start back with the stock phone, i can re-root again and start fresh.
any ideas please??
im physically tired of reading everything, misleading information and constantly flashing back and forth hoping its gonna work. oh and mandatory angry comment: thank you google for effing up my phone!
edit:
the only stock rom i tried i the 2.3.3 stock update available in clockwork. made no results.
current specs:
my phone is a i9020a
current baseband : NO DGSXXKD1
current build: GRJ22
android ver: 2.3.4
core: 2.6.35.7-ge382d80 [email protected] #1

Thanks dude, i had actually done that and did manage to get a signal back. its SMS that just wont work and when do the INFO thing to set the right value, i either get update error or a crash.
i installed stock rom 2.3.4 and install radio uckd1. that made my signal work even without having to move the efs files on the root of the sdcard. but still no sms.
is anybody else getting sms problems? this was working before the 2.3.6 fiasco.
im with rogers canada, in ottawa.
ok, just to loop the loop on this one and hoping it will be of use to somebody else.
my sms issue wasnt related to my phone at all, once i had a signal back, that's as far as the phone was concerned.
i placed a call to rogers to let them know i couldnt sms anymore.
long story short, they tried many things but ultimately, its doing the "hard" reset on the network for my phone that did it. im sure there a better name for it but basically they erased my phone from their network, i had to wait about an hour for the change to propagate. when i powered the phone back, it resynced everything and sms was back online without a single thing to do.
Hey guys I have an issue with a galaxy note I717 from AT&T, i just bought it from a friend of mine who reset to factory defaut settings and out of nothing the phone lost the IMEI, baseband and newtwork. it says it is unknown. besides that the phone kept reestarting every 2 min maximun, it would boot up to the main screen and give me enough time to check the settings, then it would reboot. I was looking for different roms arround the site and tried several differents, no matter witch one I used the phone will always reboot. I tried restoring to the GB aT&T stock rom, same thing, the only Rom to seem that fixed the reboot issue was a ICS stock room that is supposed to unbrick the galaxy, the phone stays on and everything but it still says no IME no basend no IMEI SV.
just to let you know I have tried several different modems, nothing works.
I am just wondering if you guys have any idea why the phone will only work with that ICS stock room and no otherone? and any possible fix to the IMEI?
thanks a lot in advance.
Hi there,
I see you already asked that in the correct forum here:
Lost IMEI, corrupted efs help!
Wait there an answer from the experts/owners.
Good luck
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.

Hi
Did you ever manage to get it fixed I'm having the same problem on my g920f and my imei is 350000000006 and serial all zeros
Thanks
Mav
XT925, JBBL and CWM 6.0.4.4
Has been running cm-12-20150408-NIGHTLY-xt925_jbbl for a long time.
Decided it was time to update, being JBBL there is only cm-12-20150417-NIGHTLY-xt925_jbbl which is newer.
Flashed that without issue and it appeared to be fine, however no wifi.
SIM, Bluetooth, NFC all ok, but when you turn on wifi nothing happens. Change screens and wifi is back to being turned off.
Hunted around, found a CM13 build for XT925, installs fine, everything works well ... still no wifi.
Went to a CM11 version ... still no wifi.
Rolled back to cm-12-20150408-NIGHTLY-xt925_jbbl which it has been on for about a year ... yep, no wifi.
Checked the baseband version each time and it is always vanquish_u_bp_100700.250.66.01P
I can get my way around flashing some roms, but I am no expert, so not sure if the baseband should change or if it is even related to this issue.
Any ideas or help would be appreciated.
Definite baseband problem
So after a lot more messing around, and reimaging and trying a bunch of stuff, I am now at "Unknown baseband" and have no radio connectivity at all.
There are a bunch of posts about this mostly for Samsung phones, the general theme is to get a stock image and reflash it. Or to try and erase the modem/ modemst1/ modemst2 partitions.
The issue is I cannot find a suitable stock image. Most of the links etc are dead as razr HD is pretty old now.
Its originally an Australian version of the XT925, though really that should not matter, any XT925 firmware should work I think, although I found the Rogers firmware and it bricked the phone pretty badly and took a while to recover it.
So if anyone has a lead on where I can find an image for the radio/modem or patch of that nature or has any good ideas on how to recover from this problem I would be grateful to hear.
Thanks.
some progress
well after more research, got a stock image installed, the trick was to use mfastboot.exe not the regular adb and fastboot.
Now have a baseband version back (same as before found a stock AU image eventually) however same issue as originally had which is now have mobile data connection but wifi doesn't work, auto disables when you turn it on.
Nailed down the problem to the persist partition, it was dead/corrupt.
Problem now is I need to get the files for it somewhere, I have created the wifi/bt mac addresses as there are some guides out there for that, but looks like I am missing some bin files as well.
Anyone able to have a look in their /persist and tell me what SHOULD be there?
finally fixed
After about a day of screwing around, its fixed.
Root cause, corrupt /persist partition.
The fix involved a combination of this guide
http://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576
and eventually finding a copy of WCNSS_qcom_wlan_nv.bin and a decent stock firmware. As well as a lot of reading, swearing and experimenting.
After running so hot for so long it now has a bit of a bulge at the back, I think after 4years the battery is now going ... lol.
However now successfully running CM13 and I think everything is working.
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.

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.
