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.

Hi I need desperate help
two days ago I went from CM11 to S4I9505 Google Play Edition ROM 5.0.1 and everything was running perfectly. Today I used an app known as "ROM Installer" to flash TWRP easily which it did but I couldnt go back to normal menus and it kept on booting back to Recovery. So I wiped everything and installed the same ROM as it is in my External SD. It was successful but it still would boot to recovery and nothing would work. So I thought my option was to unroot the phone. I used the XDA Unroot/Unbrick guide and used an Android 5.0. Lollipop firmware to flash the stock firmware (second time every using Odin, the first was disastrous and I hated it). I flashed the official stock and it is running but cannot activate WiFi what so ever. It just refuses to toggle. So I reflashed the stock firmware again and it still doesn't work. I was thinking of somehow downgrading to KitKat, use CM Installer which is how I initially rooted the phone and revert to a CWM backup that I made before I flashed the S4 GPE ROM and start over. However I tried using that CM Installer and since im on Lollipop it would refuse to work and I really wanna get back to how everything was before :'( I really dont know what to do (No warranty or anything on this S4) All I can do is make calls and texts. Please help!
fixed!
I've fixed it! Its all back on stock with the all that bloatware and useless features only problem now is whether there is a way to deleted this thread
Alright, I have a Virgin Mobile S4. I rooted it a year ago with towelroot and installed clockwork mod on it to install cyanogenmod. I tried it, didn't like it so I restored my backup of the stock rom using CWM.
Fast forward to now. I tried to update my S4 OTA for Lollipop, but it would give me an error. I figured it was because I had changed the recovery software. So I went and downloaded the virgin mobile lollipop stock rom from sammobile. ( I337MVLUGOC4_I337MOYAGOC4_VMC ).
I tried to flash it onto my S4 using Odin 3.09. To no avail, it always failed at the system4.img.ext or something. From there I tried to make it work by using 3.10. Still failed. I googled for a fix or workaround and found something about reinstalling clockwork mod. I also tried reinstalling the PIT file for I337M. It was still not working. So I tried to flash back to my stock backup.
1st time I flashed, I kept having program that didn't want to start errors. I wiped dalvik, I wiped cache, I factory reset. Still bugged. So as a last resort I restored the backup again after having done all this. It worked! But...
Well, I'm at a lost now, I can't update using OTA, I can't update with Odin, I can't update with Kies. Now what? Is there a way to go back to the stock recovery and let the OTA or Kies update go through unhindered?
BTW, I had a problem when trying to use EFS professional to backup my EFS before the procedure. No matter which port I used ( front port or back motherboard port ), I could never make the backup, it said something about the phone currently being offline or something.
Anyway, I'd prefer to be able to switch back to the stock recovery and let the OTA or Kies do its thing. Any clues?
EDIT UPDATE: After fiddling some more around, I changed usb port again and reflashed using a more up to date version of Odin and I finally have Lollipop on my device, only problem is that I have no 3g or 4g connectivity even tho the IMEI, baseband and SMS as well as calls work just fine, what's wrong?
See first post edit^^

Did you check the APN settings? Make sure you have the right one for your carrier.
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
Hi,
So I have a Note 3 N900W8, Stock 4.4.2, rooted with SuperSU & the usual xposed & busybox config.
I had TWRP working fine but I hadn't gone to recovery in a while, probably a few months or so & when I went a few days ago somehow recovery had reset to stock recovery.
I usually download TWRP off their website & install using a terminal on the phone itself. But the TWRP website wasn't working so I couldn't download the file, so I installed TWRP (the latest version for hltecan) from TWRP Manager which is on the PlayStore.
It got installed just fine & TWRP loads up perfect. Right after that I wiped my cache & dalvik/art. That also went just fine.
But since then, my internal SD card has been going nuts. The phone turns on perfect, everything works, apps still function for the most part. What isn't working is, SD card is not entirely readable I think & definitely not writable through apps.
ES explorer shows the sdcard as blank in every location (not a single folder).
Titanium backup doesn't even load up, just stuck at loading screen says loading app data.
Lucky patcher says SD card not mounted
Camera doesn't work, can take pictures but they of course don't get saved & videos say recording failed.
I'm guessing a factory reset would probably fix it, or not. But before trying that I want to know if there's any other way?
Please help!
Thanks!
Cheers!
Personally, I would flash the latest stock ROM from sammobile.com, set up the phone to make sure everything works, then flash TWRP and a custom ROM of your choice.

Hey yeah, exactly my thoughts, unfortunately sammobile hasn't been working for a while I think, their free servers are down :/ But 5.0 is finally available for the Canadian Note 3s! Should get on that!
But anyhow, I found the fix, there's this app on the PlayStore; Int-SdCard Write Fix (https://play.google.com/store/apps/details?id=com.vinny.intsdfixer&hl=en), does the trick! I'm guessing it's just a small bit of code but bloody brilliant!
I have a Samsung s8 snapdragon 950U, T-mobile, running android 7.0, baseband - G950USQU2BQK5, build - nrd90m.G950USQS2BQL1. A couple weeks ago the mic stopped working so that I could not use speech-to-text which I rely on heavily. Nothing fixed it until I reflashed the phone with the same firmware. Before that I performed a ROM backup using clockworkmod and moved the backup files to my computer. I also used Titanium to backup system data like sms messages. After that, just as I was going to restore data, I get TMobile message that I’ve never seen before about a firmware update. I figured if it’s Oreo the update would fail because I have a custom ROM. Stupidly I chose to update and the next thing I know I have Android 8 – NOT rooted. That prevented me from using Titanium to restore settings.
Stupidly again, I decided to go back to the android 7 firmware and proceeded to root and flash the phone as I did before. This time it failed. I tried the SAMPWN and SAMFAIL methods repeatedly without success. Now I have bricked phone that just loops through a screen that says “Installing system update” followed immediately by another blue screen with a defunct android that says “no command.” I can get to download mode which Odin sees, but not to recovery, or anything that Smart Switch(which isn’t so smart) sees.
I have been downloading the Oreo firmware G950USQU4CRE9_G950UOYN4CRE9 for the past 4 hours hoping that I can maybe flash that. HELP! Can I somehow restore the nandroid backup using my computer? What should I do. I just need a working phone or I’m in big trouble.

update: i was able to flash the oreo firmware basically puts me back at step 2. becasue i backed up when rooted my backups now cannot be restored, or can they, at least in part? Is there any way i can restore some of the data in either the nandroid or titanium backups to my nonrooted oreo s8?
