[Completed] softbricked galaxy s4 - XDA Assist

hey guys, i was trying to domestic unlock an sph-l720 galaxy s4. I followed a lot of different threads here and i felt like I was getting pretty close when i soft bricked my phone. My original modem was the L720VPUGOK3 (running lollipop 5.0.1), i used odin to flash the MDC modem. then (using odin) i rooted my phone. basically i got everything up until i started following this thread:
http://forum.xda-developers.com/showthread.php?t=2530610
which, i got up to step 12) where it tells you to add the lines
ril.sales_code=LOL
ro.csc.sales_code=LOL
then when i tried to reboot, it got to the galaxy s4 screen then went black. usually after that screen it goes to a samsung screen then a sprint screen. I can hook it up to my comp and Odin will recognize it, but no matter what i flash (i've tried re-flashing MDC and root) nothing works. i can also boot it into download mode and recovery mode, i tried doing a factory reset, but that didn't help either. i now no longer have CWM though and so when i go to recovery boot i see this :
android system recovery <3e>
LRX22C.L720VPOGOH1
With the options
reboot now
apply update from ADB
apply update from external storage
apply update from cache
wipe data/factory reset
wipe cache partition
reboot to bootloader
power down
view recovery logs
enable cp logging
disable cp logging
and i am now lost as to what to do...
update: ok so after about 5 hrs of googling, i have managed to pull my build.prop file. oddly enough i didn't see the two lines i supposedly wrote.
i used build.prop.editor app from google play but i supposed i didn't know what i was doing and didn't actually write them in the first place. so now i'm really lost, since i don't know what my problem is. i'm also having trouble finding a build.prop file to download for cross-reference. any suggestions would be great
update2: ok, after a few more hrs of searching every forum and post i could find, i managed to flash a whole new rom (using odin) onto my s4 with the thought that if i coud just get my phone to reboot, then i could go through the system update over wifi, problem now is that i'm can't turn on wifi. i can press the button but it just goes straight back to off. And since i can't use my sim, i have no way of updating it to my original rom from the phone (which i'm still only guessing is possible). i couldn't find my original rom, so i guess i'll just keep flashing new ones til i find one that works. any suggestions would be appreciated.

Problems Getting Clockwork To Run - Android System Recovery Overriding

Hi All,
I've been reading this forum for a good few days now as I am trying to get my Kyros functioning the way I need it to. However, I've run into a few problems and am not 100% sure as to what to do. Before I go on, I'm not very techy, so I would be very greatful if replies could be as straight forward as possible, without much jargon as that really loses me
First off, we've just managed to install the windows and ADB drives. I'm following all the instructions from here: http://forum.xda-developers.com/showthread.php?t=858952. That took some hacks our side, but is now working.
I'm pretty stuck on the clockwork reboot though. Again, followed the instructions from the link above. When it initially rebooted, it went straight into the Android System Recovery mode (the robot with the triangle opening screen.) I've tried it over and over, following the directions exactly as explained in the link, but all I'm getting is the generic Androis system recov.
The Recovery zip file is on my SD card. Do I need to unzip it to get the recovery.img to show? Is that something that I'm doing wrong? I also updated the OS (I guess) from the coby site before I started working on these other changes.
So basically, this is the issue right now. Trying to get the clockwork to run and all I'm getting is the android system...and that's when it doesn't just reboot back to the home screen directly.
Any advice would be great. Thanks
And out of the blue, after an hour of angry TV watching, it's now worked. I can't tell you what I did differently as I followed all the same steps as before. Must just have been lucky I guess.
I am having the same issue, and i tried to unzip the update.zip but i boot back to the recovery mode, can someone assist me with this, i have a galaxy s (Vibrant).
thanks
Try going to your sd folder and delete the clockwork recovery folder then uninstall rom manager and redownload it from the market after it installs open up rom manager and click on flash clockworkmod recovery and let it download the update.zip file and your done

Oh yeah after all those steps and you still get back into the stock recovery system click on reinstall package and it should boot into cwm I hope that helps

Acer Gallant Duo E350

Hi,
I've been having problems with this phone, everytime I turn on the data plan it keeps poping up messages that all the process have stopped working so whenever I rebooted this keeps happening.
I tried going into recovery mode (e3) and wiping (factory reset) everything but this doesn't work, everything remains the same,
So I was trying to follow the guide to root it and load cwm recovery (from this post http://forum.xda-developers.com/showthread.php?t=1899736) but it is not working.
I installed the drivers and I'm able to see my device in the windows explorer but when I start the runme.bat to root the phone it just throws a bunch of error messages.

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So i tried to load the cwm recovery using the flastool and the process completed with no problem (the green circle appeared) but when I turn on the phone it loads the stock e3 recovery mode.
Is my phone broken ? what do you guys suggest I do ?
thanks in advance
i have this problem to :S somebody can help us??
Liquid Gallant won't reboot
I've got the same issue as mentioned in the post before; does the owner found a solution for his issue?
I tried to follow the tutorial on this forum and got the same issue when installing the *. bat file. File runs but won't detect the phone and closes.
Untill now the problem persists; frequent crash and shut down while using (wathever what, phone, internet, apps,..). I have not much experience with smartphones but it seems to me the internal boot is corrupt. Are any possible tpols or hints available or should the item be returned to ACer (when you know their helpdesk and utility service is crap!)
Same problem
Hello,
I had the same problem last year. I couldn't hard reset ( tried the 2 ways: via the settings or via the volum button when you start). It doesn't reset anything. The applications closes by themselves and I cannot do anything.
Last year, I sent the phone under the warranty and they repaired it and sent to me back.
Now I have exactly the same problem but my phone is not under warranty anymore.
Does anyone found a solution ?
Thanks.

@Jonnyredcorn Did you restore from a backup? If so try from a new device
Why nt make a clean flash and see if it persists or not?
I had this exact same problem, and assuming that you did a dirty flash (did not erase your data), this is why it's being caused
After flashing Android L onto your device it is attempting to run the "First installation" screen but is in conflict with booting up normally as you have already completed the setup.
To confirm this = Try "unlocking and locking" your phone with the power button, you should see the install menu flash up briefly, for a second or less, if that's the case then you're in the exact same situation I was in
There was an old fix for this, but isn't very reliable now, it's worth a shot anyway
"adb shell am start -n com.google.android.setupwizard/.SetupWizardTestActivity"
This will force the installation overlay on top of the black screen allowing you to "setup" your phone again despite already doing it.
If this fails then your only hope is a fresh reinstall
I don't believe I did a dirty flash. I was under the understanding if I flash the factory images it did to clean white I didn't do a clean wipe and recovery prior to booting into the bootloader and flashing the factory images. I did not restore from a backup this is my first time going from KitKat to lollipop I do not see the installation screen pop up when unlocking and locking my phone

Ah okay then,
I'd suggest attempting a reinstall
If you modify the flash-all.bat removing the "-w" command, which wipes your phone, you'll be able to retain any data currently on the phone.
But as you've said you think you've wiped over it anyway, just complete another wipe over the device and flash it again, better yet download a fresh ROM first
OK so my issue was I forgot to flash the userdata.img which caused me to dirty flash. I just redid the whole thing and it's working it's working perfectly now thanks for all your help guys

Hey guys! i have an issue here. can anyone help me solve this problem.

I tried to flash stock firmware, i downloaded two firmware of INU region (India)
everytime i get the following error on odin,
(Above pic for reference only. im using odin v3.09 and latest)
I tried flashing with PIT files, it didnt work.
I tried flashing TWRP, CWM it flashes recovery but when i go to recovery then still philz is there.
I searched on many forums and Googled, and i came to know that my /data and /sdcard is corrupted. but i can access the content /sdcard from recovery and i can view my files.
I tried flashing other custom rom. It flashes them without any error but when i reboot my Tab its not flashed. its same.
What to do please help me.
Ok so after doing so mush research on this on xda, gsm-hosting, google, etc....
i came to a conclusion that the emmc is corrupted or right protected (Means It has become read only). which is why we are unable to flash through odin or through recovery. even if the flash is successful then after reboot the TAB returns to the earlier state i.e same rom, bootloop and recovery.
so there are three way you can fix it:
1. change motherboard, which is very costly. on ebay it was 13k (India). dont know about local shops or service center. but im sure it will be more or less same.
2. Change emmc. ask the repair guy to change the buggy emmc to a new one. buy the emmc from alibaba online store or other online stores if you cant find it offline.
3. You can get back the same tab to work by directly flashing the stock rom directly to emmc. This process involves soldering the pins of the tab and flashing directly on to the chip using a box called ATF (Advance turbo flasher). This process is little advance, one can do it if you know what pins to solder (You can get the idea from youtube & gsm hosting), but buying atf box would be costly. costlier than the emmc replacement. now if you want to experiment and learn you can go buy a atf and revive your dead tab (it will be called The walking dead. ).
:)
so i am replying to my own thread so that if any body is comes searching for the same gets to know what happened and what to do next.
BTW Android_Andi has done some great research on this he tried every possible thing but unfortunately it didnt work. Thanks to him for his time and effort.
and if anybody figures out how to fix it without using atf box please do post and let me know. because im keeping my dead tab with me and if someone knows any alternate way i can fix mine too. who knows anything can happen.

Bootloop on Samsung Galaxy S3 with TWRP and Lineage OS 17.1

Hello guys, so basically you are my last hope since I cannot find a solution for my problem (at least with my level of knowledge).
Lets start from the beginning: I (someone with no experience in this topic) decided to try out a new OS on my old Samsung Galaxy S3 since a lot of apps stopped working on Android 4.3. I tried a tutorial on youtube on how to install a new custom ROM. I installed TWRP (3.5.2_9-0-i9300) and later with the help of TWRP Lineage OS 17.1 (an unoffical version for my type of phone) and everything worked perfect.
I started to download all apps I need and to customise my OS. In the end when everything was set up I decided to do a full backup using TWRP and thats where the problem started. In the development section I checked the function, that when you press the power button you can directly boot your phone into recovery mode. So my phone rebooted and ended up in a constant boot loop where at first the Samsung Galaxy logo appears (first picture) and then TWRP appears (second picture) and this process goes on and on...

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Sadly there is no way to get into recovery mode since this loop just continues. If tried it many times also with taking out the battery and putting it back in. The only thing I have access to is the download mode.
So my question to you: is there anything I could do in the download mode to solve this problem? I saved the important data before so a full wipe wouldnt be a problem. Maybe I can do something with odin?
I really hope you can give me some ideas to try out. Every help is appreciated. Thanks!
Try reflashing a stock ROM first of all.
Then reflash TWRP. Make a TWRP backup (especially the EFS ! That is a "must-do first and foremost" !) of your working system and progress from there.
And in the future, instead of reinstalling all your apps piecemeal I strongly recommend you use Titanium backup (paid version. The free version is very limited), that is a wise invesment for the small sum it'll cost you
@Snakeforhire reflashing stock ROM worked, thank you so much.
I will take a closer look on Titanium backup. Used it in the past but with root access. On the new Lineage OS I dont have root although it shouldnt be hard to get from what I read.
