sounds like when you restored the info from your old phone it borked something. If you made a back up before doing that then I would restore it. Otherwise you will need to most likely restore to stock or if you were on a custom rom reflash it.

try factory reset, never ever backup that kind of stuff, unless it's via LG tool.

Stuck at Samsung logo

Hi all,
I was hoping someone could shed sime light to my situation. I have a rogers S4 and I rooted it via motochopper and it worked fine. Restored all my apps from Titanium backuoband all was well.
This morning my phone then got stuck at the samsung boot screen and I had to wipe data via the stock recovery to get iy working again...
Can anyone tell me why this is happening? This is thr 3rd time this has happened

My guess would be the titanium backup. As it can mess things up, once in a while.

I would blame TB mess ups more on old data being restored that causes problems, than TB itself.
OP... Are your app backups from a different ROM? If so, then I would try restoring without data. Or fresh app installs.
Sent from my SAMSUNG-SGH-I337 using xda premium
are you restoring system apps? or just user apps? if you are restoring system apps or something like the messaging storage, will normally cause problems in TB.
best to just connect to wifi and download all the apps again from playstore.
What I would do is odin back to stock do not restore anything for a day or 2, and monitor it. If it never does it again, then it was your backup, keep in mind some apps that worked on the G3, may not work on the G4.
Yes, this is Titanium, it happenned to me too, remember that doing that is like copying everything in the C: Program Files of a PC, formating the computer and restoring that folder, it might work, but you might end up in a lot of trouble overtime since the OS installs different part everywhere. Use Carbon aka Helium, its a much cleaner way to go
I was restoring apps (with data) and the backups were from older ROMs I used in my nexus 4. I am currently trying a non-rooted method for a few days and see if this problem reoccurs

UPDATE: so far so good... My setup is currently unrooted and I haven't had this issue appear. I'm gonna root in a few days and monitor it again

cool

Phone has no mobile data or phone service.

Ok I really screwed the pooch on this one. I'm not sure how I did it but I used the cf auto root and cw recovery and flashed the wanalite rom and everything was fine. Then I wanted to try out a new rom so I flashed a cm 10 rom and had no data except wifi. When I turn wifi off there's no little 3g icon and also I can't make calls anymore. There's no little bars at the top only a little circle with a line through it. Ive tried factory reset, flashing the original firmware, messing with the apn settings and so on. Anyone help please?

A little more info. I flashed twrp recovery and used that to make a back up. Then I wiped all the stuff you're supposed to before flashing a new ROM. Now here's where I screwed up. I then wiped the data. The one on the right that makes you type in the word yes to wipe it. I didn't realize it would wipe out all my back up s and everything. So now I can't get my phone to work. If I have to end up taking it in for an insurance claim what should I do. Unroot and use triangle away. Then tell them my problems. I really don't know what to do here. I need your help as I'm not very good at this stuff. Anyone have any fixes?

Best I can tell ya is download a pre rooted rom, should be a mega thread of them and install via odin.
Real simple instructions there.
That should get you back to normal.
Gd luck

Sorry , you're unlucky man. You just wipe all partitions including EFS (IMEI/baseband lost). Only thing is sending the phone to Samsung service and maybe they will change the motherboard or reflash it. No ROM/firmware contains those hidden partitions so flashing your own will not help .

What does your phone display if you call the following?
Code:
*#06#
It should display a valid IMEI then.

I think that your phone is quite messed up, from the installation point of view.
You have to try to get totally back to stock.
Get your FW from sammobile (the one that matches country, operator, etc). Get stock recovery. Install both, then do (several) factory resets. It should work....
I would not go on very high level workarounds (reinstall PIT< etc), as you might totally brick your phone.

Yeah it's got the little circle with the line trough it and I tried your link and nothing but I've been seeing some things about not using the front usb port on your computer so I'm going to switch to the back one and try everything again. I'll report back when I'm done.

i doubt the usb port will change anything mate...i still have the circle with the line, not sure what to do right now. i have flashed everything to stock, rom, kernel and recovery still same ****
I had same issue on mine but mine is all stock (for now). I had to go back to the settings and pick network operator again in order for it to pick up the network again.
Well I got it fixed. I had to fully unroot then run triangle away and then take it to the sprint store. All they did was a hard reset (not a factory reset but something with their computer) and everything was back to normal. Whew thought I was going to have to get a new phone.
Sent from my SPH-L720 using xda app-developers app
hi, did you check first in your apn list if the settings were present (connexions - more networks - mobile networks - access point names )? If not present check on your operator website to get the information needed. Normally It should have helped you with this problem
Yeah I messed with that for hours. In many different roms. I think I did every thing I possibly could except for hard reset.

[Q] Need help restoring my Nook Simple Touch

So I've gotten myself into a real mess with my nook. I was playing around with it and accidentally deleted my user partition and when I was trying to repair it I ended up wiping it of everything... So as I've been trying to fix it with Nook Manager which creates a backup but I don't think its a functioning one because when I press restore backup nothing happens. I also tried doing a factory restore but it says the factory restore.zip is missing. I can't find either a backup img or a restore.zip for the NST online anywhere. Is there any hope or is this thing gone for good? I would really appreciate any help people can offer.
Can anyone please test this for me?

IMEI Problems

Hello Guys,
im facing a problem with my i9505,
I've been using Liquidsmooth Rom for some time,
and yesterday i flashed some roms, and now my sim card isn't recognized anymore, aswell my IMEI and Baseband are missing.
I've had that problem before, so flashed stock rom and restored a TWRP Backup containing only my EFS folder.
This has solved my problems in the past, but now nothing happens.
I have a TWRP backup aswell as a copy of the EFS folder.
Has someone else faced the same problem or knows how to fix it?
Thanks in advance.
No one?
Try to restore efs folder manually with root explorer
Sent from my GT-I9500 using XDA Free mobile app
I'm trying right now, but I am confused because the restore with TWRP doesn't do anything to my EFS folder.
Ok, I copied the EFS folder from my microsd back to the phone but nothing changed :crying:
Have you tried flashing back to stock with Odin? I've heard that can sort out IMEI problems and the sorts.
Even if it doesn't it gives you a clean phone to work with, so you can eliminate any rom problems.
I flashed the stock rom, as well as different modems trough odin, but nothing changed. But I'm wondering why the TWRP restore doesn't show any result.

Thanks Mate, I'm still trying. If not, I found a service to repair it for 25 Euros but I hope I will be able to do it myself.
Try to Download another stock rom and before flashing it do a full wipe, including formatting data and cache. Something similar happened to me a few days ago. I've flashed a russian rom and problem solved, but I have the i9500 model.

Not sure if this will work, of it you've tried it already, but have you tried a different version of TWRP?
I did actually, but I'm going to try a older version too and see if it works.

Ok, tried restoring with TWRP 2.500 and it shows me failed, contrary to TWRP 2.7.
With TWRP until 2.6.3 it shows me failed, 2.63 and 2.7 show me a succesful message.
LOL it just started working again without me doing anything :highfive::laugh:

I think it's BRICKED this time!

Ok, I was on a custom ROM for LS980 and all of a sudden it rebooted and I had no control of anything. There was no service either.
So first thing I did was a reboot. no good. Then I went booted into TWRP and restored my last backup, thought this would surely fix it but nothing. Still booted but had no functionality, plus now it started to go into a boot loop. Tried recovering different versions and no luck.
Then, I decided to use the Flash Tool recovery method. It worked in the sense that there was no longer a boot loop, but I still had no service and could not use a lot of the functions like updating PRL/PROFILE and few of the apps would not launch like the quick remote, it would say "SIM not ready"
I'm pretty much out of ideas at this point as I only have the flash tool option and since I lost recovery.
Is this considered BRICKED or does anyone have an idea? thanks

If you are still able to enter in the ROM it's not Bricked....
Put the phone in Fastboot and flash a recovery via Fastboot commands.
Then you can wipe everything (except internal) and flash a new ROM.
I've never fastbooted before. Is there a quick tutorial link for this?

There is no normal fastboot mode as on other phones. Best thing i think try to go back to stock via kdz/tot method and reinstall root and recovery

So I tried the flash tool again using different TOT files. ZV8 and ZVA files caused boot loops. The only file that almost worked was the ZVC file. By almost I mean, there's no boot loop, and i'm able to use the stock ROM however certain things don't work, like when launching the quick remote app, it says "SIM not ready", or stock video cannot play "Unsupported file type" error, and most importantly I'm not able to get any service.
The good part is, my wifi is working. So next I tried to root, however I get this a "unable to open /system/xbin/su: no such file or directory" (i'm attaching the photo for reference).
Thanks for any other tips of directions.
remove sim card and reinsert try that. Not working.
also check your imei. If its not there you may need to recover it from a twrp backup, (recover the efs that is) at least from the time you had no issues. Not working?
Also I read nothing about wiping. (wipe everything except internal sd) before performing a clean instal. Check for same issues, not there victory.
be carefull with full backups, they might contain the issue you are experiencing.

this is a ls980 so I can't remove the Back cover unless there's a way I don't know.
Also, I lost twrp recovery when I used the flash tool and tot method. Now, i'm trying to root and get recovery back but can't even root.

I am not very familiar with your model. But on the d802 there is a small slot on the side of the phone with a small hole. With the phone in box was a small metal device which you could poke in hole and the slot would open. Maybe other user could confirm.
Did you backup your twrp backup of the phone? Then now is also the time to put it back if the tot method deleted it.
Anyway did you check your imei, (dial *#06#, it should show your imei). usually when service is lost there is something wrong with imei, or simcard.
imei can be recovered by the efs backup in a twrp backup. Simcard via putting out back in, reboot, etc.

Thanks for all your help! sounds like its definitely a imei and Sim related issue.
I don't have any backups but I can get to the factory recovery which has an adb side load option. Do you think I can side load a stock ROM this way? If so, what type of file do I use?
