[Q] Boot loop cause of build.prop? - Galaxy Grand 2 Q&A, Help & Troubleshooting

I edited build.prop and added a line that disables boot animation.
Now it's stuck at boot animation.So, wiping stuff doesn't work... This phone is so bad, seriously.
Now, how am i supposed to edit build.prop to fix this without turning the phone on?
And no root explorer doesn't see my phone although every usb option is on.

help?

the ADB out of date error describes that adb service was running previously thn too u started new daemon process..
therefore,
first confirm that u have latest adb
then kill adb.exe from task manager
then start adb again..
there wont be such error anymore then..

Thank you for your reply but nothing i do solves my problem.I'm trying to fix this for 3-4 days because of a simple build.prop file And not being able to flash anything from odin or recovery is making it worse.

does download mode work?
if yes thn try Odin (run as administrator) and plug ur phone into a different USB port and let drivers install..
thn flash stock rom..
if the above didnt helped,
then do following:
1. boot into recovery mode
2. do factory reset and wipe cache partition
3. plug ur device to PC (another port) and let adb detect..
then if you type adb devices, it will show device(serial no.) recovery
4.then perform further steps i.e editing build.prop
hope this solves your problem!

[Q] Super Ultra Brick (WITH VIDEO)

UPDATE 3: I've got it back to as stock as I can get it. I think I'm going to just return it and get a new one. Thank you all for your help.
UPDATE 2: As of right now, I'd like to completely remove FFF from the device, but I can only use fastboot to do it. I have absolutely no adb access. Is there a way?
UPDATE: Here is a video showing what is happening to my KF: http://www.youtube.com/watch?v=MH6oUg1NmC0
I hate to start another thread about boot loops/bricking, but I'm not sure what's going on with my fire.
I had CM7 installed successfully since the day after Christmas. This morning I woke up and my Fire was being really sluggish, so I rebooted it (I did not select reboot into recovery).
After it powered on, I was stuck at the CM7 boot screen (with the skateboarding android). I let it sit, but no luck. I went into TWRP to try and restore the backup I made of the stock rom. It looked successful, but when I rebooted I was stuck at the Kindle Fire boot screen.
Next, I tried wiping the device and re-installing CM7, but I received an error (something along the lines of E:Error unable to find /tmp/sideload/blahblah).
So I again restored my backup of the stock rom. Now when I power on my Fire I see the yellow triangle, then the kindle fire logo, yellow triangle, kindle fire logo, and it just keeps repeating. The problem is I am unable to connect to adb because the PC only seems to recognize the adb device for a few seconds after the yellow triangle, which does not give me enough time to fix the problem.
Any ideas?
looks like you'r out of battery ! the kf is rebooting !
would take the wall charger and charge for an hour
it's not possible to charge with the computer - it lasts forever
then it should respond in a stable state

Recovery shows my battery level to be at 53%. I've got it on the charger now, but I have a feeling there is something else going on.
Also, I am unable to mount my Fire's SD to my computer in recovery. It looks like it is working, but my computer never acknowledges it.
maybe because your last installation failed
nevertheless i would try to charge and then go in twrp and retry the installation
if that's not sucessful i would try to switch the kf to fastboot and copy a new rom. stock or prerooted stock or cm7 - whatever you like
in twrp there is a point "mount" - sdcard - then you should get it from computer

Thanks for the reply. Is adb required to get into fastboot? The problem is that I am unable to get into adb because my computer only sees the Fire for about 1 second. When I go into device manager, I don't see it at all.
EDIT: Yeah, I see the mount in TWRP, but it does not do anything when I select it.
Hi Im a beginner but Id like to try to help :
In case you become desperate ignore twrp's battery display and try wall charger.
Anorher idea id have is to shut down throughr twrp and start up then instead of rebooting.
ADB is needed to get into fastboot, but it's quick. If you use KFU, you can probably hit the option during the couple seconds you have available. I would say your best bet, however, is booting into twrp, doing a full wipe of system, cache, davlik cache, and maybe data, and then trying the rom install again.

So this time it looks like the installation worked in TWRP, but after reboot now I'm stuck at the CM7 boot screen. This is at least some progress, so when I get home I'll see what I can do.
Sent via my internet connected mobile cellular telephone.
Well, the battery is definitely not the issue. I've been trying to get fastboot, but the problem is the fact that I can not get adb. Has anyone else had issues with getting adb? I've already tried to install the drivers, and that doesn't work.
EDIT: I've tried issuing "adb devices" from the command prompt repeatedly as soon as I hear the ding until it disconnects a second later, but still I have had no luck.
Also, I found this thread in which someone else appears to have had a similar issue to mine.
[Q] New kind of unfixable Super Brick?
at the moment adb is useless - you should try to get the device in fastboot mode - correctly recognised from your computer - then work with fastboot commands - if you don't get that then your next opinion is buying or making a factory cable - but we should try to avoid that ...

I can not seem to get fastboot to work either. Does fastboot rely on adb? Or do you just run the .exe file? I tried to run it, and nothing happened.
fastboot has nothing to do with adb - calling just the exe does nothing -
you have to issue fastboot commands
ok have reread the whole thread and have some ideas:
your currently stuck at the cm7 boot screen ?
have you used the "stock rom version" to wipe data and cache partitions as described here ?
http://forum.xda-developers.com/showthread.php?t=1390773
perhaps it will help to wipe data/cache with twrp ...

OK, so I restored my original rooted kindle rom, but I still can't get into fastboot because of the problem I showed in the video. It is doing exactly the same thing, just instead of the CM7 boot screen, it is the Kindle Fire boot screen.
Is is possible to get into fastboot without the computer? Can anyone think of a reason why I would not be able to mount my device in TWRP?
I just want to understand something about fastboot... can you upload and flash roms with it? Or can you only get TWRP / FFF with it? I ask because I already have them, and I still can't do anything (mount from inside TWRP doesn't work). Thanks!

with fastboot you can install the newest fff and if you need twrp
but with the newest fff you can issue ""fastboot oem format"

Cool. I just ordered one of SkOrPn's cables, so once I get it I'll be sure to give an update. Thanks for all the help so far!
The cable isn't need when you have the FFF bootloader, in fact, when your computer does see the device for the short amount of time shown in the video, fastboot is active. It's a feature of FFF. Fastboot is a command line tool like adb but is used for different things. It comes in Android sdk which if you have that, you should update the tools packages in the Android manager and it will update adb and fastboot. It looks like something is not working correctly in twrp and the OS is failing to load. I'm not sure you need to oem format tho.....
At some point you had to have used fastboot to install twrp and/or FFF.... Unless you used adb dd? :what:
Anyway, I can help more but it's late where I am, need to sleep. Was going to write more but... Need sleep lol. I'll post some questions and check back tomorrow.
Have you used adb before? Do you know if platform-tools is in your environment variables PATH? In other words, can you open up cmd and type adb or do you need to "cd" to platform-tools then use adb? If you know where adb is located? If so, is a file called fastboot in there? (Maby called fastboot.exe)

Yep, I've used adb successfully, and it is set up as an environmental variable. I actually installed FFF and TWRP with the KFU. Problem is I think something else is botched; perhaps it is TWRP itself, since I am unable to mount from TWRP. I'll try again when I get home.

[Q] DEAD N4? Not Really but failed to root and install recovery

I tried to root my phone today by using the Nexus 4 toolkit. In the process of rooting the phone, the use connection is physically disconnect by myself well it was an accident. After that, I only got unlocked bootloader, but I am not be able to get the recovery and the SU in the phone. When I try to repeat the steps, it is stucking at " cannot connect device" or sometimes "failed ... unknown error" or even "protocol error"(if I remember correctly. It seems that the connection is gone between the phone and the desktop under the fastboot mode. But under the normal Android OS, I am able to connect my phone to desktop to do the data transfer things.
I am seeking for help here. I hope I explain my problem properly that you guys can understand. Here is error I got sometime when I connect my phone to PC.
The button is OK in the pic.

[Q] Won't boot after ROM install

Hello! My first post here on the forum
So I've got this problem that my Samsung Galaxy S4 won't boot properly after the rom install.
The recovery I've been using is CWM and after the install when I press reboot the phone vibrates and the "Samsung Galaxy S4 GT-I9505" screen shows up and then the phone immediately shuts down again. Now I can't get the phone to start... :/
Thanks, Joakim.

Hmm alright, I tried to flash 4.2.2 google edition. But the problem is now when I go into recovery my phone can't find any ROM to install.
It feels like it's broken. And I've got no adapter for the micro-SD card so I manually can put in a rom to the SD :/
I can get in to the CWM recovery but in "install zip update package -> choose ZIP from sdcard" there is nothing. So all I can do is try to get a rom into the external SD and flash from there?

Try and plug it to your computer then keep power and wol down pressed for like 15 sec: now fastboot should stick and device shouldn't reboot, so you can flash a recovery (TWRP?) and start over with a new ROM.
Thank you for your reply,
It still doesn't work, penguin stays on screen but it's not recognized by computer ( before the brick it was)
I'm not very experienced in rooting btw.
Edit : The recovery.bat in the file X1_X800_TWRP_Recovery2.8.7.0 says "Complete! The device is ready to reboot into Recovery." which I do but it keeps reboot with the pinguin on.
I recieved my phone today and it just wont stay in fastboot mode. I can do anything I want but it just keeps rebooting before I can flash anything. Any suggestions on how I should keep the Phone in Fastboot mode?
You need to install drivers. After that it will not reboot anymore. That worked for me atleast.
What kind of drivers do I need? Please link them to me I have tried a lot of drivers. The thing is that the phone also does not stay in Fastboot mode when not plugged into the PC.
It's my topic for my problem so don't ask questions for you on it please u_u

I have downloaded drivers (I think) from https://twrp.me/devices/letvle1pro.html where I also get twrp 3.0.2.0
Btw if you are using Windows you can open Device Manager and there you will see your device and what drivers it has installed (you can always use update drivers function, maybe that will help too).
Here is a little guide how I managed to get twrp:
Just download it (drivers and intall them) (and download twrp also). Place twrp file to the folder where you have your adb installed.
In phone settings go to developer menu (first you need to unlock it) and you need to switch on usb debugging.
Connect phone to the pc via usb.
Open command prompt in your adb folder and type Adb devices (if you have drivers installed corectly you will se your devices connected under some code).
Then just write Adb reboot booloader and phone will restart to the recovery.
Type into the comand prompt: fastboot flash recovery name***.img (where the name is the file name of twrp you have downloaded- just a tip: rename it so it is easier to remember for example to twrp. Then the command will look like: fastboot flash recovery twrp.img)
If succesful, write fastboot reboot and that is all.
Btw for me it did not work first time. I had to load twrp for second time and when I wrote fastboot reboot then I immediately pressed volume up so It went directly to twrp recovery.
Hope it helps. Cheers
I have this problem
Hello
I have your problem have you solve this?
Thanks
Hi guys. I have a problem! My letv x800 CN boots to TWRP but doesn't start the system (EUI logo loading all the time) I don't know how to transfer ROM into the phone in order to flash it. I installed all the drivers and PC recognize it. PLEASE HELP!!!

[Help] I bricked my Axon. Need help.

So i've gone through every thread here without success. I have a unlocked bootloader but no OS nor custom recovery and i cant get into fastboot mode to install twrp. When i use ADB it wont find my device unless i go into Stock recovery -> update through ADB and even then it only recognized my device as sideload. What can i do? When i tried to use the MiFlash tool i cant seem to get the correct qualcomm drivers installed. what can i do?
Edit: I solved my issue by downloader the stock B08 system on my S5 and then i placed it in the external sd. Then i put the SD back into the Axon and installed the system. After i had installed the system and booted into the OS i could enter adb with my device being recognized and after that i flashed twrp by using ADB.
I have a new problem though and that is that i can't install the 3.1.0.0. twrp. it only boots into black screen when i enter recovery. I can use the 3.0.4.0. version though.
You can't enter fastboot mode on your phone. Correct?
I also assume that you installed a ROM from recovery and that's what caused the brick, right?
What happens when you try to enter recovery?

Go into My Computer, manage, devices and try to uninstall all drivers that are possibly related to your device.
Unplug your phone and let the drivers reinstall by itself.
Go into ADB and see if ADB Devices works.
If possible go into ADB reboot edl and try to reflash custom recovery : "axon7tool -w recovery"
When recounting unplug your phone and see if you can reboot, shutdown and enter into TWRP.
ps : i hope you have a backup ?

Correct. It simply reboots.
Yup, i tried installing the B29 stock system on my G model and so i suppose i had the wrong bootstack becasue this is where my problems started.
I get to the stock android recovery.

It still wont recognize my device. Which driver am i supposed to have in the Device manager? Do you think i can use my old S5 to transfer a Stock system to the sd card and then update my phone manually through the stock recovery and then when i have an OS installed maybe i can connect to ADB. I read somewhere that ADB commands only works in recovery and in the OS.
I have a twrp backup of my system on my SD card so no worries there.

You should see your phone as QUSB_BULK. Installed the ZADIG drivers ? That may cure the problem.
After that, imo, it is important you can reboot edl and flash TWRP recovery again AND when it recounts, you pull usb.
Normally you will have replaced recovery , reboot ok and you can enter TWRP and fastboot also.
ps : sometimes it is also advisable to go to ADB RECOVERY directly and do the processes.
ps2 : when TWRP backup, you can always put it on SD via other phone and in TWRP restore. Normaly you're good to go then...
Try the Marshall London Bootloader Interface driver maybe?

Installing the driver and using it for the phone (device manager -> change driver manually (or something of the sort)) worked for me, but it could differ. Let me know. You don't have to uninstall other drivers just use that specific one for your phone by switching the driver manually via device manager.
