[Q] Stuck in Boot Loop - Fix without Reset? - G3 Q&A, Help & Troubleshooting

In order to fix my issue connecting to WiFi access points, I decided to delete the files within the /etc/wifi folder (was supposed to delete /data/etc/wifi?)
Since doing so, my phone has been stuck in a boot loop, not allowing me to change much on the phone in that time (maybe 5 secs).
I don't have a recovery installed (just the root with towelroot), so don't have a nandroid backup, and stupidly didn't take a titanium backup.
I do have a backup of the deleted files on my External SD, so could put them back in place, if possible.
Does anyone know of a solution to fix the boot loop, without wiping my data?
Or an option to backup at least my SD Card (ideally data as well) before I factory reset?
Thanks

Idk if it can help, but I did recovery from PC Suite just to get the KDZ of my phone.... It took his time so I went to dinner but when I came back my phone was already flashed. I didn't lose my data or apps it just flashed over it and unrooted (but you can root again).

Here are the answers:
Next time before mase with the root files backup all to SD or PC.

The problem I have is that I cannot get PC Suite to see my phone or connect to it - Probably because I can't get the MTP driver to install.
I've been looking for the KDZ file for the 32GB Eurpean D855, but I have not found it as yet. Also not sure which DLL file I am supposed to be using for Flash Tool!
I did get so close to moving the files back to their correct location, but need like 1 second extra before the reboot!

Have you tried to boot in secure mode? Maybe it can give you more seconds.
Just hit power button and when menu comes keep pressing shutdown until appears the message to boot into secure mode.
Also you can try the twrp method and use adb on it to restore files.

Managed to get it recognised on a Windows 8 machine, rather than a Windows 7 machine (yep, strange huh)... managed to restore using PC Suite - no data loss, so i'm very happy!

I told him on first reply. If you flash to recover through pc suite, it just flash over it without deleting anything.. It just unroot but you can root again.

As above. Even if it seems phone is not recognised in Pc Suite (but seems to be in Windows) connect phone and in LG PC Suite select Mobile Device > Restore Upgrade Errors

Bootloop began after I though I did a mod and saved the 644 permissions.
PC Suite does not find the phone, even in with above method.
Other ideas?

[Q] Help Needed for Lg g Pro E988 Please.

Hello:
I just got me an LG G pro E988 and rooted it using the "ZV9-ZVB-Universal-Root" it worked very smooth and nicely,
and downloaded ""FreeGee Free **ROOT Required**"" after booting to recovery made a backup using ""FreeGee Free **ROOT Required**""
then rebooted to verify the backups after reboot, using explorer+ to enter data folder, true to the work, I was able to find the backup I just made, at the internal sd card, data/media/TWRP folder 2GB+!!! but then but then I saw the kitkat! and got excited to upgrade, downloaded the ROM from Cyanogen and saved in my external SD, then I booted to recovery and in the recovery mode at the **Teamwin** menu I wiped and formatted data, system, dalvik, internal storage!!! (I wish I had not done!!) then I clicked install, but ""FreeGee Free **ROOT Required**"" teamwin"" could not locate my new kitkat rom! the external SD card is not visible, so I thought ok let's restore the new backups!!! but the "teamwin" could not even find its own backups!!!! the folder under data\media\TWRP is just vacant nothing in there and no options either just the back button!!! now I can not even do a hard reset to restore by factory reset either because there is an error message and a success boot!!! the "teamwin" boots successfully LOL!!!! I even tried the latest LG PC Suite to restore but the drivers for MPT can not get installed keeps on failing to install so could not even transfer my ROM .zip files to the internal SD to try to install from zip....!!! my device has been rendered USELESS!!! please help, Anyone I am hoping for advise and sulotion!!???? tnx and please in case of any advise just email me at [email protected]
Hi
Don't worry you can solve this using adb sideload you will be able to transfer files to your phone
http://teamw.in/ADBSideload
http://www.youtube.com/watch?v=CivvxcM1PCY
thanks for advise
thank you so much for your reply
I did read and watched the video in the links you sent me, but my version of the recovery is "team win recovery project
v2.6.3"what they are using and discussing is v2.6.3.1 which comes with a usb mount mine does not have the option or
it is not capable of mounting a usb device I could have transferred the ROM image to the internal sdcard! and my computer
fails to recognize the MPT port and fails to install the drivers for it so no luck yet in using the adb push! or if I am doing
anything wrong please help if you can.
even the LG PC suit is not detecting the my device properly, even when I connect to LGMobile Support Tool and
change the language and country to Singapore! ( its where I have bought the device!) and install the drivers for LGE988
which is the exact unit I have, it does detect the device for a few seconds and goes up to %18 but then it says disconnect
your device and remove the battery and place it back in the device while holding the restart button! I follow exactly as
instructed but when I plug it in again as instructed it goes few more % but again keeps on saying the device is disconnected
RETRY and I keep on retrying with no luck, that's all what it does!!!
I hope you or other guys who have had the same problem with me could help and share experience to solve this little
BIG problem
Thank you very much for the taking time to help....

Hard Bricked LG E980 USB device not recognised

My LG E980 is bricked. I can access download mode and that is it! I am unable to boot into recovery,
and the hard reset screen simply sits there forever. My computer only recognizes my device as an "unknown usb device."
I'm unsure what can be done about this, but I feel like this is better than the infamous QHSUB icon displayed when the device cannot be recovered.
Does anyone have a remedy for this problem?? I have GOT to fix this phone and can't afford to Jtag the device, but I'm losing hope that this is possible, PLEASE help. :crying:
Have you installed the LG drivers for your pc and tried the unbrick method?
Yeah dude there's an unbrick method. If this doesn't work just sell the phone on Ebay. http://forum.xda-developers.com/showthread.php?t=2302660
There is never a time when this device cant be recovered. even the qhusb is a fairly simple fix. ill go ahead and make a sdcard boot image tonight. do you have a 32gb sdcard? (or larger) and an sdcard reader, if you have those two things i can make an unbrick.img that you flash toi the sdcard and put in the non-booting phone and it will get you to download mode/recovery mode. ill have to check out what partitions are where as i dont wish to include my efs along with it all .

Happened to me.
1. With the phone on download mode and plugged in the computer; uninstall the unknown device on your computer using device manager. The computer should try to get the drivers for your phone.
2. If it doesn't. Repeat step one and install the drivers first.
That worked for me hopefully I'll work for you.

I do have a 16gb sd card, but I can pick up at 32 gb sd at my local best buy. I have an Asus laptop running windows 8 and it has an SD card reader. I am a little confused (semi-noob) as to how this will work because my phone will boot up, and the led changes colors on the home button for about 4 seconds and then the light stops flashing. The phone is stuck on the LG boot screen, and there is no way out of it but to pull the battery or to reset with power button. Of course no recovery as previously mentioned. I really just want to get back to stock, but I can't manage to get both the windows 8 computers I've tried to detect the phone in download mode. Ever since I switched to the Candykat rom 4.4 the computer wasn't able to recognize the phone, even when the phone was fully functional inside the rom.
I have tried it on my dads windows 7 laptop as well with no dice. Instaled LG drivers, uninstalled LG Drivers, uninstalled device from the Device Manager. I've done everything I could think of. I previously was in a Philz touch recovery, but every rom I tried to flash wouldn't work. I tried to flash another recovery from inside it and then the device bricked like it is now. What a head ache. If you think this method would work, I am more than willing to try it, just unfamiliar with what I need to do on my end.
Okay

I will give your method a shot, but I have done this a lot already. The only thing I can think of is I usually unplug the phone from the computer right after deleting the drivers and uninstalling in device manager. Maybe I should just leave the phone plugged in and see if the computer automatically downloads the drivers, but I don't think it will because I've tried to update the drivers before. It gives me an error code "10" and says the device has malfunction or stopped working This phone has been undetectable via USB since flashing the candykat 4.4 rom. Every computer I've tried (3) and every USB cable (3 again) has displayed it as an "unknown device"

I dont know lg's download mode, kdz, tot etc all that well. im more of a samsung guy. however qualcomm since the s4 chipset has allowed for sdcards that are properly formatted to boot the os instead of the internal emmc. here is a decent guide, just need to make teh image for this device. this will let your device boot no matter how bad it gets you are welcome to try with 16gb, the rule of thumb i know of is as big as teh emmc is use that same size or larger sdcard, however some people have had sucess withs maller, just not many that i know of. http://forum.xda-developers.com/showthread.php?t=2439367
however afaik the only way to reflash teh bootloader partitions is via kdz/download mode so perhaps the sdcard will let you get into that mode and then you can flash, so long as you keep your sdcard like that it will boot fully, but in order ot get your sdcard back you need to repair teh files on your phone .
Thanks

Wow, that sounds awesome. I followed most of that. I access download mode on the device by pressing vol up and down simultaneously and plugging in the usb cable. I am more willing to try this, and if it works I will pay you from my paypal. I guess all I need now are those files to run to the sd card. I read the tutorial you posted for the samsung and downloaded the windows disk manager. I am eager to try this method, though it is admittedly very new to me.. If you can post those files, I will follow the instructions you give and pay you a little bit of money for your help!
I am a broke college student so it won't be much, but I really appreciate your response and information on this method with the qualcomm s4.
Here is the unbrick image. follow the guide for your platform (gunna guess windows) and write this to your sdcard after backing it up. from there you need to restore your partitions by flashing them .

Okay so I bought the 32 gb sd card. Just wrote the .img file you sent me to the sd card.
I powered on the phone and nothing happened, I got the same LG screen where the led flashes and then stops.
I followed that guide, but am I supposed to go to download mode instead of just powering on the device?
I got a little confused by the samsung jargon lol. I just want to know after I've written the unbrick.zip to the sd card
how do I get my phone to recognize the card is there? And once I am able to do that how do I "restore my partitions by flashing them?"
I do have the factory firmware set to flash through lg flashtool, but the phone can't be detected of course due to the usb issue.
Just want to say thanks for walking me through it this far, I feel like I'm close hopefully but unsure what to do next.

you wrote the image to the sdcard? i wonder if its because you still have the low level bootloaders that it may not be booting from the sdcard, normally this is done to fix qhusb errored devices. as for restoring the partitions all you would need to do is one its booted up push the unbrick image to the phone and use rooted adb shell to write it back onto your phone.
Possible hope??

I meant I used the windows tool to write the debrick.img to the sd card. But no dice, the device isn't recognised.
However! I installed a driver clean up tool and now if I plug in the device it is recognized as Android Original ADB Interface.
The LG Flashtools even says the port is ready! But I get the error code "10" "device cannot start, A request for the USB device descriptor failed."
So now I am stuck on that instead lol. This just sucks.
that sucks about the sdcard, it must be because you arent "truly" bricked. sorry i thought it would help ya :/.
What is the driver repair tool you used? I know this thread is old but I'm having the same problem. I was trying to root my E980 and now my computer wont recognize my device. The phone works perfect, its just when I plug it in to the computer it isnt recognized. How can I fix this?
+1
Just wondering if anyone's come across a solution to this besides a sledge hammer... been having the same "Code 10: Device failed to start" when in Download Mode, though Windows finds a driver fine when the phone is stuck on the LG screen... doesn't help much, though, 'cause it won't receive adb commands. I manually installed the LG USB Composite Device driver, which added a modem and a COM port, both of which Windows recognized to be active, but the LG FlashTool USB Viewer showed no open pipes. I'm a relative noob, so please feel free to point out the obvious, like an alternative to adb that the phone can always receive or a way to brick it the rest of the way so the MicroSD trick will work.
I came across this problem like the OP and just wanna let everyone know that you have to use computer with USB 2.0 port then the driver issue would be fixed.

PC Suite Problem

Hello. I was experiencing alot of shutdowns and reboots in my LG G3, so I decided to make a factory reset. I did the backup via LG PC Suite. Everything went fine. When i finished the factory reset I connected the phone via MTP and I can't find the phone. The weird about this is that the phone shows up on the "Computer" folder. I tried to unistall and reinstall the PC Suite, and tried to install the drivers by hand. Nothing is working and I can't find a solution. I just need to extract the ECBK file, because now I got no contacts and I can't find a app that open this file. Thanks for ur time

How to get T-Mob S3 off (third) Samsung splash screen to access data

Can anyone please assist to get data off an S3 which sticks at the blue-backed throbbing SAMSUNG splash screen just after the android rocket take-off.
The history is that the phone started constant-rebooting and I left it off for a few weeks. Then I took it into a shop to get the power switch replaced and the repairer noticed that it no longer reboots, it just sticks at that SAMSUNG screen. When neither of us could get it into safe mode, he diagnosed that it was "definitely" a software problem. Resetting caches from recovery mode doesn't do anything and as I am trying to get data off it, I am a bit reluctant to follow other solutions I have found here and do a master reset!
I THINK this device is rooted (with towelroot)? See below
I can get to an Odin screen and can get the device recognised on the computer and wondered if I could do resets from there with one of the 4 files included with 3.07. Curiously enough one of them did succeed (though the success was too quick to convince me it had actually flashed very much) and the device did reboot but still got stuck at the same splash screen! Taking the battery out and restarting/cleaning caches again etc didn't help and now, none of the Odin files will 'flash' successfully, which is why I am not sure if I am still rooted or if something is returned to stock. I am just not sure which file or what exactly flashed successfully and what it did to the ROM, bootloader, CID, etc etc etc. SO I am assuming that if I can still load Odin and get the S3 recognised, it is still rooted.
Is there anything else I can try either through odin or independently to get me into the os please? I have loaded skipsoft and run it and it has connected to the S3 (and changed things) just by connecting to the computer in download mode: But I can't see where in skipsoft I can diagnose or correct whatever is wrong
Flash TWRP via Odin, boot into TWRP, mount data partition, connect the phone to a computer, and try to copy the phone's data to the computer.
What that guy said ^^^ Install a new OS for your system which should replace your old one. You don't need to boot TWRP if you are going to boot a new OS. My method involves you losing all your data so you have been warned. You can get the stable version for that here http://techbeasts.com/update-t-mobi...o-android-4-3-jelly-bean-t999uvuemjc-guide/2/. Good luck
Thanks for that guys but I have apparently already loaded Philz and it SAYS it has backed up the data and/or storage to sc card and I am wondering if Ican restore it to a new Galaxy J7. I especially need to figure out if I can restore telephone text messages from the S3 onto the J7 but i could make do for the moment with knowing whether such messages have made their way onto the SD card.
Yes, I am a bit reluctant to do a full wipe and restore until I can figure this out.
Or if I can access the files through my computer as you suggest, what file / format would they be in?
If you used Philz to create a backup, I don't think you'll be able to restore the data to the J7, but I could be wrong because Philz hasnt been updated for a long time which means there may be no Philz for the J7.
Philz can only be restored with Philz and possibly cwm.
I got Philz installed through Skipsoft but am wondering whether there is any newer utility I can install over whatever Skipsoft has put there? Or is that what TWRP is?
I am a bit reluctant to install anything through TWRP if it is going to not only overwrite the OS but also delete all the data I am trying to access! But is there any utility which might conceivably get my phone working again without deleting all my data please?
If I load T999UVUEMJC_T999TMBEMJC_TMB,md5 through Odin, will it delete all my data??
Flashing twrp should not over write the rom, only the recovery.
Was the phone recognized as a removable when it was booted into philz?

Why did you ask me that? 'cos I was pretty sure it was recognised but checked again and it isn't recognised by the computer at all when I plug it in (and obviously isn't recognised by Odin)
Philz shows as Touch 6.26.6 and ClockworkMod v 6.0.4.8
Why would I ask? Because twrp can mount the phone as a removable drive to copy off the data as you wanted to do in your original post.

Sorry to harp but are we agreed generally that there is no way of getting this phone working again, - whether with some utility or by re-flashing the stock or some new ROM?
Once the phone starts hanging at that third throbbing SAMSUNG screen, is it effectively dead save only for the purposes of getting data off it as a media device please? I really need to access my text messages and couldn't even identify them on a file directory and wouldn't know what format they were in if I could access the file browser. That was sorta a last resort but I am now downloading T999UVUEMJC_T999TMBEMJC_TMB for installation through Odin? Or for installation through Philz if I can get the file onto the SD card.
Did you try twrp and use a otg usb?
It really depends on how much your time is worth.

I will keep retrying to see if it is something I am doing wrong but whereas Skipsoft installed easily, i dont seem to be able to install twrp on this nonbooting pda?
If the phone is not recognised by the computer, either the drivers are not working properly, the USB port is damaged, or the USB cable is not compatible with Odin.
Until the phone is recognised in Odin, you can't flash a stock rom from sammobile.com.

If the phone is not recognised by the computer, either the drivers are not working properly, the USB port is damaged, or the USB cable is not compatible with Odin.

I am not exactly a newbie at this but I am beginning to wonder if I havent just got a developing massive hardware failure. I have tried a number of computers, including ones which formerly recognised the computer/cable/S3 setup and none can now recognise the phone, eg in Odin.
The phone is detected on plugin to Windows 10 (with the recognition beep) and is then not seen in windows explorer. Changing cables doesn't do anything. I am assuming it should automatically appear on the drop-down menu in TWRP's app in the playstore. That menu only shows a phone I plugged into the system about 6 months ago (without it being rooted) and asks for root permissions on this now-nonexistent phone.
The phone is not now recognised as it was up till only a few days ago in XP. Nothing is now recognised on a Mac, though on all three units the phone charges.
Restarting in download mode a few times changes nothing.

The only other thing I can think of is putting some TWRP file (?) on an SD card, booting into recover/Philz and can i not install TWRP or reflash some ROM from there?
I'm not sure if twrp can be flashed from Philz as I have always flashed TWRP via Odin.
You have done everything I would have done to get the phone recognized short of a installing a fresh installation of a Windows OS.
You could also try Heimdall (http://glassechidna.com.au/heimdall/).

Locked bootloader by mistake, can't use the phone now

Hey all,
I just got a OnePlus 5T and because I needed a specific system language I decided to flash a custom ROM. I unlocked the bootloader, flashed Derpfest on it and it was all good until I made a mistake. From the Developers options I unchecked "OEM Unlocking" and then when I restarted into the bootloader I did a fastboot oem lock
Now the phone says it's corrupted and it won't boot. Since it's bootloader is locked I can't unlock it, I can't go into recovery and I can't start the phone. Is there anything else I can do to get it back? I don't care about wiping everything at this point, I'm just trying to get it back to a working state.
I want to add I did try the Unbrick tool https://forum.xda-developers.com/oneplus-5t/how-to/oneplus-5t-unbricking-tool-confirmation-t3733012 but I am getting stuck at the drivers. Windows won't see QHUSB_BULK in device manager and I don't see anywhere else where the driver for the phone might be. I do see the device when doing fastboot devices but again, can't see what drivers is using.
Thanks!

The unbrick tool is your best bet, what you need to do is follow the instructions. If its windows 10, you can go to device manager and update drivers from there. Make sure you are logged in as admin. Also some antivirus don't like the MSM tool so you may need to disable that.
Ensure the sequence is right. Connect usb wire to computer, press volume up, connect usb c to phone. Some ppl have tried pressing both volume up and down at the same time to make it work (same way as resolving Sahara error). If it boots first thing you need to do is back up efs.
Second you need to run these commands
adb shell
su
dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img
exit.
It will save the persist.img on your phone internal memory. Save this as well as efs somewhere safe. Also share the persist.img with me cause I need it for the OPlus 5t for my phone.
Hope it helps

Thanks for the help! I ended up finding a different Windows PC with no memory of the drivers for this phone so I was able to install them in the correct order and then run the MSM tool to get the phone back to stock Oreo. From there I unlocked the bootloader again to install TWRP and then my custom ROM.

That is superb. If you could do the other bit I would really appreciate it.
Thanks

Hey there, sorry I totally mis-read the last part of your original post as something that I should do and I didn't see that you need that. Since I used the MDM tool I didn't bother to try your way first and since the phone wasn't mine to keep I already gave it to the owner so I don't have access to it anymore.
Again, very sorry about that.
No dramas. I also got it from some one else who was kind enough to lend it to me and let me root it and wipe it clean and then get the file and start using his phone again.
Thanks
