Hi,
I own a GS4 - i9505G - with google ROM edition v 4.3.
yesterday I tried to upgrade the ROM to 4.42 (Google ROM clean version without any tweaks, found here: http://forum.xda-developers.com/showthread.php?t=2341026).
After the upgrade, the UI & ROM seem to work fine but I have no carrier signal.
When I perform the mobile networks operators' search I can see all networks and by clicking "Choose automatically" I managed to renew the signal. However, after a very short while the signal is lost again (manual joining to the network does not work at all).
I searched and found this thread: http://forum.xda-developers.com/showthread.php?t=2192025
and this lead me to use ODIN and flash the modem (twice, as recomended).
I used the modem file exactly for my phone base version which is: XXUBMH1.
However, even after flashing twice - still no signal....
Since I had Nandroid backup (always VERY highly recommended) I returned to the original 4.3 ROM version and then everything worked fine.
I also made another try to identify the issue and installed the 4.42 Google ROM edition which is not the Google clean original version and performed a factory wipe and cleaning everything
(this time the ROM I used was downloaded from here: http://forum.xda-developers.com/showthread.php?t=2557353).
However, same story and no signal....
I would very much appreciate any idea how to solve this issue.
By the way - from December I began to receive a notification on the device that an upgrade ROM was downloaded requesting me to click to install. However, when I tried to operate it the process always failed in the first steps (don't remember the error code). If anyone can direct me where to delete the file that was downloaded - it will also be very helpful due to the low free memory on the device.
Thanks in advance for all the help!
I now that for some roms you need to use TWRP recovery, or you will get "no signal".
Try flashing the rom with TWRP recovery and see if that solves your problems.
thanks but no cure yet

Thanks for the advice!
However, it seems that the cure is elsewhere. I had the PhilZ 6, and now converted to TWRP, but issue stays the same.
It appears that the signal is not totally lost, but the network connection can only be maintained for a short while, and only after a reset and when choosing automatic network registration. Soon after the signal disappears.
All other wireless aspects (WIFI, BT) seem to be working fine like before.
I am still breaking my teeth for a solution here...
Thanks.
Why are you installing a rom for the i9505 on a i9505G?
That would probably explain your issues.
You say that your phone is I9505G, but both of those roms are for I9505. Don't ever do such thing. You're lucky you didn't brick your phone. Check your IMEI
thanks for the note

Indeed I didn't notice the difference and thank you for this very important note.
I would like to elaborate - my phone was bought as a standard i9505, but I installed a clean Google Edition ROM on it and then checked under "Settings"/"About phone" menu to see the Model number "GT-I9505G".
I am now not so sure that this is the true model of I9505G, even though this is the information shown on the phone. If the model relates only to original Google Rom Edition phones then I am wrong and probably confused you.
My IMEI is: 3576********. Can you help me with the true definition and the files that I need to install?

First of all know this: You should never reveal your IMEI, it's not safe. Edit your post and hide your Imei number.
Now check again if the Imei that you see inside settings> is the same as the one from the back of the phone, under the battery. If its the same then you are fine. As for the device model, you can also find the model under the battery, and if it says that it's a i9505G than that should clear all the confusion.
My advice would be go back to stock official using ODIN. Grab the latest firmware from sammobile. It's always the safest thing to do, and it should handle all the mess
its a I9505

Many thanks for your message - even though I feel stupid both for not thinking to check "under the hood" and also for publishing the IMEI (now fixed).
It appears that my phone model is I9505. This validates my initial question, how to update the Google Edition ROM (clean version) from 4.3 to 4.42, but avoid the loss of network signal... I will try to take it to a local store and solve my unknown issues with the upgrade by paying a few bucks.
Many thanks anyway!

My last guess is that you are using an incorrect modem. Are you still on the old bootloader?
If you are already on the new bootloader, just flash the latest modem available. If it is correct that you have XXUBMH1, then you are using a modem that is to old for 4.4.2.
this is very true

I think that this is the correct problem identification and that my modem file is not updated for 4.42.
I tried to flash the updated modem file for XXUBMH1 version (in this link: http://forum.xda-developers.com/showthread.php?t=2192025), but this did not solve the problem (even after flashing it twice).
Could I flash a different modem file than the one set for the phone base version which I have (or do I risk bricking my device)? and does the base version change after installing the new ROM (I forgot to check this after the new ROM was installed)? If yes then I will re-install it and flash the new modem file which should solve the problem.
Thanks for helping out.
Which modem did you flash? And are you on the old or new bootloader?
Hi all, I'm pretty experienced with flashing roms but I've run into a problem I cannot fix.
I bought a Korean version F320L and it came with stock 4.4.2. I rooted and then tried a few roms. Moved back to my saved stock rom because of battery life. As my signal wasn't great I looked for an updated radio. I found cloudyfa's modified baseband and it was a newer baseband than my current model. I flashed it and the phone rebooted normally but found no SIM card.
I've tried a number of fixes:
1. Factory reset - nothing
2. Restore stock backup - nothing (I hadn't saved the radio.img - will next time)
3. Flashing to stock, first a Kitkat rom (Korea LG U+ KitKat_F320L21P_00.kdz) then a Jelly Bean rom (LG U+ F320L11G_00.kdz)
Still always the same, no sim cards recognised (I've tried a few different ones that work in other phones).
Can anyone offer help or insights?

So I've been trying everything, I restored my EFS partition backup and used the LG Mobile Tool to reflash. Again the exact same problems. All I can guess is that flashing cloudyfa's modified kernel whilst on stock rom tripped some kind of sim/country lock, but I find no mention of such a mechanism anywhere on the web.
:crying: some help or ideas would be appreciated.

Hello All,
Please forgive me if this is the wrong area to post this, this is my first post here.
I have a Galaxy Note 3 SM-N9005 that I purchased. The previous owner had it rooted and the leaked Lollipop 5.0 installed. I tried to flash it back to stock (Australian) however it near bricked it. It was running really slow, a hell of a lot of lagging. I installed the DirtyUnicorn Lollipop 5.0 custom rom, and the phone runs fine, except for the fact it has no radio (i.e. no 4G/3G/2G connectivity and no telephony).
I searched for days and days on end looking for a modem/baseband compatible but nothing seems to work. Would anyone have any info on how to get the radio working? I really don't care about going back to full stock, as long as I can use the radio. I have included some photos of the system info and the sticker under the battery.
Thanks for your help,
Christopher H.
Restore your backed up EFS .
Pointless flashing a modem with no IMEI .
Hi Guys,
semi-noob here. I have a galaxy s4 (sprint) model sph-l720 that I have activated on Boost Mobile carrier. I got it used and it works fine. I was very unhappy with battery life. I saw a way to convert s4 to s5 by flashing customer rom and thereby getting the ultra power saving mode. I followed the guide but since I'm new I can't post the URL the ROM is echoe rom v29 s5 port part v
kernal 3.4.101-v5.1
I could not root it using there method and even though twrp installed it would not initialize. I found an autoroot file that I installed with ODIN and it worked, phone was rooted. then I installed ROM manager from the play store and installed CM Recovery. that worked. then I installed the echoe ROM from that page. it all worked but now some things are not working. getting xposed not activated messages, mobile data shows a connection but I can't access the network. some other things now wokring either. it also changed my model number to GT-I9505, which I thought was weird...should I be concerned about that? . also it's android 4.4.2 and it might be better to have 5? . So, after all that, my question is to recommend a ROM that is newer but still have the power saving mode, that hopefully fixes the things that are not working. my main concern is battery life and performance. I don't care about things like themes. I hope that makes sense and I appreciate any help. Thanks
Yeah you got a long way to go.
You cannot and should not flash roms from other devices to your device. Unless it's stated that it will also work on your device. You also should not follow guides on those wannabe tech blogs unless it on XDA. If the guide is a Youtube video, then skip it. All those guides suck and are usually incomplete or outdated. For example you flashed a v29 version. When I look on the website of echoerom their latest version is v58.... And besides that there isn't even an sph-l720 version available.
Bottomline:
You flashed an outdated recovery, you flashed an highly outdated rom that's for the I9505 and not for your phone. No worries, you didn't brake anything.
This is the section for your phone.

1. Use TWRP instead of CWM. CWM is outdated and should not be used for our phone anymore.
Hello guys,
I am verry sorry to bother you with this, but I am just to dumb for this part.
I am quite familiar with the whole custom rom business but I try to fix my mothers phone where I installed a Cyanogenmod custom rom (12.1) some time ago.
She experiences some mobile network issues which, I guess, are related to a old baseband / modem version causing troubles.
Can you tell me which version is the right one to flash via Odin or preferably via twrp?
I plan on updating it before installing the lastest 12.1 CM snapshot.
I believe she has the Samsung Galaxy S4 I9505 International with LTE and Snapdragon processor.
Under baseband version ("About the phone") it says I9505XXUEML6.
(I dont know if this is correct I can remember that I once installed a Google Play Edition Rom to get rid of the bloatware).
The phone was bought in Germany.
I know that you guys are probably busy with more important stuff but I'd really appreciate it if you could quickly help me with that.
Have a great day.
Thank you in advance.
Update: I got the files, changed the cable Odin passed but no version change!
Update 2:
Manually going into fastboot instead of using the reboot menu did it! Thank you so much. (Maybe add that info to the guide to avoid similar problems with othe people)
Thumbs up & good night!
