I've searched and searched here and everywhere and do not have a clue how to get mobile data back after a bad flash of a custom Lollipop ROM. I have the Verizon G2 and would appreciate any suggestions. I've been working on this all day and haven't found any answers that worked.
I keep trying to go back to the ROM I was on before, but I stupidly deleted the files and the 1.3GB download keeps failing after an hour or so. Tried to install it via computer, but apparently it is too big to move via cable.
I did install a different KitKat ROM, but still didn't have mobile data (only wifi).
The computers I have access to have real trouble recognizing and acknowledging my phone, so I can't (yet) go back to stock.
I'm at a loss.

Hi guys, my phone has had a little problem occur, my usb port is no longer working, can't charge my phone etc...I have got spare batteries so that's not an issue but naturally I want to be able to transfer and flash things over usb cable....so to do this I need to put phone back to stock, I've tried flashing the stock Rom that came with it using mobile Odin pro, this was five except Wi-Fi didn't work and when typing *#1234# I had no csc(I had also flashed triangle away prior to this) only I still had philz recovery not stock...so I tried flashing my backups and kept getting failures...I have since managed to flash the Google stock djembys that I happened to have on internal sd.
Can anyone think of tell me how to get everything stock Samsung again? With no usb connection!
cheers in advance
This all started when I ran out of data on my device and decided to root it so that I could use the SD card. I had previously rooted a droid 2 and a galaxy nexus so I wasn't a complete noob but I'm not in any way a programmer and I had never used Odin. So not wanting to mess with things without having a back up I followed some tutorials and downloaded the android sdk and used adb to back up. I thought I was doing a full system backup but whether I made a mistake or this simply doesn't back up everything I don't know. The file size should have been a clue but I missed it. I did get my apps
I then proceeded to follow the tutorials on this site for rooting the device. They are all for the GT-S7710 but I was hoping the letter (L) was a program only type thing and wouldn't make a difference. I used this guide http://forum.xda-developers.com/showpost.php?p=40232503&postcount=45 and downloaded the DEODEXED Version. I then rebooted the phone and everything appeared to be working fine and I was rooted. I could have sworn I had data. I then realized that I didn't have CWM as a recovery so I downloaded and installed CWM recovery http://forum.xda-developers.com/showthread.php?p=43294839 It was after rebooting (and maybe a reset I can't remember at this point) that I noticed I had no data.
So I flashed a few other ROMs including VANIR (and the recovery he suggests) http://forum.xda-developers.com/showthread.php?t=2689519 I and CM 11 plus a stock rom (S7710LUBAMC1_S7710LUUBAMC1_CHO Samsung kies tells me CHO is the region for my device) but didn't have mobile data in any of them.
Still hoping to get mobile data working again I flashed a stock Recovery and A stock Boot.img from here...(Well I can't seem to find the thread now). It was a link to the stock boot.img and stock recovery.img (GT-S7710) from someone wanting a CWM recovery built. I then reflashed the stock ROM from above still no mobile data. My flash count in download mode is up to 26 lol and nothing I have tried restores the mobile data although as long as the phone boots, I do have wifi.
Is there ANYthing else I can try? I would really like to have my mobile data back even if it means I don't get to root.
No data connection
It turned out my no data was caused by not having any APN settings after flashing the custom ROM. I copied the settings from hubbies phone and now data works fine. I can't believe I spent so much time working on this and trying different things when it was something so simple.
This is somewhat urgent because I am leaving the country for two weeks on Friday, and need a working phone. I am not sure what happened today, but my Sprint Galaxy S4 (SPHL720TBK) wouldn't connect to WIFI at my house. My tablet would, so I know it was a phone issue. I rebooted then was going through settings, and just checking things. The phone rebooted itself, and when it came back up, it went through a couple of screens, one of which asked about activation. It seemed like it was installing an update from Sprint, which it had been trying to do for a week or so. But it kept failing, saying it didn't have enough space for the download, despite there being several GB free internally and on the SD card. (I figured it must be because it was rooted). After a couple of additional screens on which I could only answer OK, the phone rebooted again, and that was it. It would not boot again. I decided to power off the phone and deal with it tonight. I can boot into recovery, and connect with Odin. I can boot to recovery and connect with ADB (in sideload mode). I know I could just do a factory reset, but unfortunately, I do not have a full backup since the end of January, and I would rather not lose everything. The phone was running v 4.4.2. I had rooted the phone several months ago with CF Auto Root using CF-Auto-Root-jfltespr-jfltespr-sphl720.tar.md5, so it was essentially stock, but rooted. Is there anything I can do to get the phone back on its feet that will not lose everything? Or anyway to copy data from the phone with it in this state? Any assistance will be VERY much appreciated! Thanks!
Fixed it myself

Since I didn't spark enough interest for anyone to offer advice, had to spend most of the afternoon/evening fixing these problems myself. Everything seems to be working, so I thought I would pass along key parts of this hard-learned lesson in case anyone else finds himself in such a situation.
First I booted into adb sideload mode, which is all I could do anyway. I installed philz_touch_6.23.9-jflte.zip and the aromafm.zip. I was then able to boot into a "normal" recovery mode. Aromafm was troublesome, and I eventually had to manually put the zip into place for it to work consistently. These are both WONDERFUL , and I highly recommend them both. Thanks very much to the creators! I used the file manager to find the files that I didn't want to lose, and used ADB to pull the files over to my PC. (ADB pull <source> <target>) Then I did a full wipe and factory reset. That did little other than delete all my data, which I had already copied anyway. The phone still would not boot past recovery.
I tried to use ADB to install a new ROM, but got a variety of errors. My phone being an L720T, there are not many ROM's available, at least not for which I could find functioning links. I finally found a TAR, L720TVPUBNG5_L720TSPTBNG5_L720TVPUBNG5_HOME.tar.md5, and used ODIN v3.09 to install that.
I still need to go back and re-root the phone, and install lots of APPS and restore data, but at least I have a functioning phone, and I can do the rest on my plane ride tomorrow.
I found the information I needed in a variety of posts here on xda developers, and would not have been able to get through this without all the helpful advice posted to other threads. So thanks to all of you for the wealth of information available here!
If you want to read the below learning experience you may gain some knowledge but at this point I believe my method may have flaws. While it seemed fine at first the problem listed directly below could not be fixed without using Odin to flash a stock ROM back onto the phone. It had checked the hidden menu settings for MTP and ADB and PDA, CP etc and all were correct (I have another good working S5 to compare these values to). I tried an earlier restore of a TWRP backup and that just blew up with all sorts of FC's on boot. So thank goodness for Odin. After flashing the stock rom it booted fine and I can now write files from the PC to the phone again via USB. In the process right now of re-rooting, installing TWRP and doing a restore of my last backup.
Note : I have found one problem I am currently working on after using this method. I can hook up the phone to the PC and get a link, open folders on the phone and can copy file from the phone to the PC but can NOT copy files from the PC to the phone. More later .....
I've got a Samsung Galaxy S5 from US Cellular. Other than a few people in the Motorola subforum here trying this I haven't seen this exact method described here so apologies if I missed it somewhere - tried many searches. It seemed so easy - maybe it is just considered SOP for some - don't know so I'm going to run the details by here anyway in case it saves anyone some trouble. Do read my warnings below though before you attempt this.
1 - You want TWRP installed (or Philz CM Touch will probably work too - seems a bit more complex though) If you are flashing ROM's having TWRP or some other custom recovery is always a good idea and I'm sure most people have one of them.
2 - Always do a complete backup with TWRP before flashing anything new. You did a backup before going to Lollipop didn't you?
3 - So you are tired of the white screen, battery sucking, quirky Lollipop or maybe that Cyanogen Lollipop mod didn't quite work for you and you want the old Kitkat back. So fire up TWRP, go into Advanced wipe and wipe Dalvik Cache, System, Data and Cache. You aren't done wiping yet though. After you swiped to wipe those go back to the previous page and Swipe to Factory Reset. That may not actually make any difference but I just did it for good measure and my method worked great.
4 - Now without out even needing to reboot find your latest backup of Kitkat 4.4.2 that you have on your Internal SD or External SD card (you do keep one there don't you in case your phone glitches on you while you are out and about?)
5 - Do a Restore of everything - Boot, Recovery, System, Data, Cache.
6 - Reboot. You are done.
Firstly I need to add that I had flashed Cyanogen Mod 12.1 (Lollipop 5.1) after following directions here in the main Cyanogen subforum to flash that on my KitKat 4.4.2 Galaxy S5 phone. What may be noteworthy is that after flashing CM 12.1 I ran the App PhoneInfo Plus (made mostly for Samsungs) and the OS version showed as Lollipop 5.1 but some of the build numbers to my recollection showed 4.4.2. So this was not a stock Lollipop OTA - it was the Cyanogen mod of Lollipop made by developers here. I just assumed they started with Lollipop to make that latest 5.1 build but I haven't followed the Cyanogen mod much at all so I don't know if they have borrowed bits and pieces of Kitkat in their builds. If they have done that then this downgrade method may not work the same for an OTA Lollipop.
Another warning - I noticed in the Motorola subforum here that some people bricked their phone trying this type of downgrade with TWRP however I believe that is because they had Verizon phones with locked bootloaders and that is not the case for my phone (US Cellular) or any other phones beside VZ as far as I know. If you have a Verizon with locked bootloader beware! I will also add that on my first boot after restoring Kitkat 4.4.2 that the second the home screen was up I started quickly scanning through my app pages and the phone rebooted itself. I believe it wasn't fully done loading the OS and it just was a hiccup. It has not happened since after trying all sort of things. Everything is working great.
I saw most people recommending to use Odin to flash a stock Kitkat firmware back on the phone in order to downgrade from Lollipop. Then you need to re-install all your apps or maybe do a restore of a recovery but with this method using TWRP you bypass most of that and get it all done in one TWRP session.
Another note about what I read people having a problem with upon downgrading - some were losing their IMEI when using Odin to flash the original firmware. I still have my original IMEI with no problem. That is another reason I think this method may be better than using Odin for this downgrade. I'll add that there are a lot of people around here with a whole lot more knowledge about flashing and custom ROM's than me so don't take my ideas as hard fact without doing your own research for your particular phone and particular situation.
I can copy FROM the internal and external SD card to PC but not PC to either internal or external SD card and the permissions seem to be correct for the folders I'm trying to copy into. Anyone have any ideas on that? However I was able to use AirDroid (Wifi) to copy files to the phone from the PC - no real surprise there but it reaffirms that I can write to those folders - just not with the USB cable.
More info. I just decided to run the App KitKat external SD Card patch. It failed. I believe I ran that before flashing Lollipop and it worked but now it fails. ?? I don't know if it is related to this problem since both internal and external SD are having a problem - but only via USB.
I tried another Galaxy S5 with same computer and cable and that one works fine to copy to the SD cards so that eliminates the cable or computer. AirDroid - Wifi works but only a problem one way with USB - WTF?

Well thanks to TWRP AND Odin all is well once again in Androidland
Hey everyone, let me start off that I love XDA and I have been using this site for years! So let me give you a little history. I am still on 4.4.4. Recently I finally updated it to 5.0 and retained root, sweet! I also had a custom lollipop recovery that allowed me to go back to 4.4.x. However, I needed the wireless tether function and I could not find a way to get it unlocked without flashing some mod (which would brick my phone) so I used ODIN to flash back to a rootable tar image that I have always used. It was 4.4.2 on NI2 Kernal. Now normally, no matter how many times I ODIN'ed it, flashed it, restore a backup, everything would be up and running in no time. However, lately my phone has not been able to connect to the network completely for some reason. I can make/receive calls and texts. Anything using data though would not work. I called Verizon to see if they could reset something from the back end and they saw me and connected and running. Needless to say, their help ended almost immediately. I am currently running Ricks ROM v19.2 G900VVRU1ANI2 and was only able to connect to data one time a couple of days ago. I had to restart though and when it booted back up, it lost the data again. It does show that I am connected to 4G LTE, strong signal. I have tried the stock ROM 4.4.2, fresh install of Ricks ROM, restore my backup of Ricks Rom (maybe two weeks old), tried Eclipse ROM, nothing seems to be working. I've never submitted anything on here asking for help so this is a first for me cause normally I can fix any problems I create, however, I cannot figure this out for the life of me. Does anyone have any suggestions that I can try? Thanks in advance!
