Nasty Bootloop after Flash on Sprint G2

Last night I installed geefree on my phone from the app store and used it to install TWRP. I downloaded a nightly CM11 and an appropriate gapps. Using geefree I rebooted to recovery (never figured out the button combination to boot to recovery "naturally") and installed both of the zips. This could be where I made my mistake, I installed both at the same time.
Now my phone loops, displaying the LG logo for a few seconds, then shutting off and rebooting before repeating the process. I can't seem to get it to go into download mode or the recovery menu. I've tried power+up, power+down, down+up and each of those while plugging the device in, etc. I can get the device to a hardware key control mode, though it doesn't seem too useful.
How can I save my phone? This forum has been a great resource in the past and I'm very grateful for the many tutorials I've followed rooting other devices. Hopefully you guys can save the day once again!

Volume up plus power is how to access recovery on sprint.
What stock sw version were you on before you flashed cm?
Did you wipe data before flashing?

I was using stock 4.2.2, I believe. I didn't wipe the data (shame on me), a bad habit that I picked up from my first rooted device, the Samsung Moment. It didn't ever matter on that one, afaik. Thanks for the reply!
Edit: Volume up and power whether plugged in or not takes me to the hardware key control mode screen.
Second Edit: http://forum.xda-developers.com/showthread.php?t=2432476&page=35 I also found this thread where someone seems to be experiencing similar issues and they fix it with "LG Utility." Is that a PC application? It's a little vague to google, but I've been trying!

I have a bootloop issue every time i flash a rom i have to wipe all but sd flash roms and gapps the i do a restore from twrp and oly restore my boot image only and they boot no prob

I'm kind of starting to suspect my power button doesn't work at all for whatever reason. I have a lot of difficulty getting the phone to shut down, then it doesn't seem to easily power up. It's a strange collection of problems. Would a Sprint repair place be able to fix this?

If they have parts on hand if not either a swap out or a sendoff

Same problem here - bootloop and no download mode - CWM works! - urgently need help
I guess I have the same problem as InlineFourPower (apart from that my power-button has no problem).
I am stuck in bootloop since I tried to upgrade to Kitkat a few days ago. Now I can´t get into download mode any more, nor into fastboot or anything else. Only CWM works.
From within CWM I can successfully flash ROMs but that doesn´t help, since afterwards I am still stuck in bootloop. It is possible, however, to push files via adb-commands while I am in CWM.
Does anybody have an idea how to go from here or how to get download-mode back?

Device is recognized but can´t be mounted - bricked forever?

I tried a few things on Linux.
After terminal-command "ls /dev/sd*" when the device is unplugged from the computer I get "/dev/sda".
When the device is connected via USB, I get: "/dev/sda /dev/sdb"
So sdb is my LG G2.
So I went on to the next command: "gdisk -l /dev/sdb"
As a result I get: "Problem opening /dev/sdb for reading! Error is 123."
Does it mean that the phone isn´t mounted or what? Now I´ve connected my phone to another Linux machine with the same result. It is recognised (p.e. as sdd), but there is no sdd1. Seems as if it is recognized, but can´t be mounted. Does that mean my device is bricked for good? That´s it?

to get the phone into download mode you have to plug the usb cord in and hold VOL+, so to get this right as I have a case on mine, plug the usb into the phone first then hold VOL+ and plug into usb port on the computer.
it does take a loooong time to power down the phone with the button when stuck in a boot loop, just keep holding it until it shuts off, it will shut off eventually!!
plug the phone in while in download mode to install drivers and set com ports, then unplug before you begin your flash with LGFlashTool, hope this helps you out.

Thanks Cronic2009 for your advice.
There are, however, szenarios where download-mode is not accessible any more. Neither by using the hardware-keys, nor by using the adb-command.
After four days of resarch and a lot of trial and error, I finally unbricked my F320L using the two adb-commands outlined at the beginning of that thread: http://forum.xda-developers.com/showthread.php?t=2451696
Worked like a charm.
Thanks everyone for your advice.

no problem buddy, glad you got it figured out, good luck to you from here on out!
FYI, that link doesn't work
I just wanted to ask anyone who might know, since the bootloader of the LS980 is locked, we cannot "break" this correct, so no matter what commands we decide to run through root, we cant touch the true bootloader there for LS980 fail safe? (Besides Acts of God, EMP, ect)

Thanks for letting me know. I corrected the link in my previous post.

Be sure if you use a aosp based rom to flash the ZV8 modem. Your can use dr87 or furnance kernals after you flash the zva modem althought i have encountered soft brick due to this.

so i'm having this exact issue and i don't know how to get out of it. i just need to transfer the radio to my phone somehow but nothing shows up under adb devices. i'm trying to the lg mobile support tool now. its downloading the software. but if it doesn't work does any one have any fixes?

After using tot and flash tool to get back to stock, did you try going into stock recovery and do a factory data reset? I know it sounds stupid especially after a tot but try it. Couldn't hurt

Borderline noob here, so please bear with me...
I have been using TWRP 2.7.0.0 to do all my work, and I was able to get the Lego ROM installed with ZVA. I got into too big of a hurry and forgot to make a backup of stock. I've also been unsuccessful in trying to install ZVC modem and firmware. Thankfully ZVA works as does the LEGO ROM, but I'd like to have stock there to access as well. The stockZVC that's on the Android Development page has been getting stuck (bootloop?) on the Sprint Spark logo. I've done TWRP's factory reset with no success. Any help would be great.
Thanks in advance!

Yes sir I've tried that and more to no avail is there anything I can do through adb I'm on stock recovery phone doesn't stay on long enough to install anything

[Q] Bootloop, can't access Recovery Mode

Hi All!
I've checked all similar threads but I haven't found any solution to my problem, hence this post.
I was trying to root Samsung Note 2 and install Cyanogenmod but rooting failed
The current problem:
1. Samsung Note 2 has ended up in a bootloop after failed rooting
2. I can't boot the phone in the Recovery Mode
3. The USB Debugging Mode was not activated
4. I can't turn on the phone
Description:
I was trying to root my friend's Samsung Note 2 using the following method from this website http://forum.xda-developers.com/showthread.php?t=2291827
- Download and unzip the CF-Auto-Root-....zip file (see posts below this one)
- If you end up with a recovery.img and cache.img file, you've extracted twice. You need to end up with a .tar.md5 file - don't extract that one
- (USB) Disconnect your phone from your computer
- Start Odin3-vX.X.exe
- Click the PDA button, and select CF-Auto-Root-....tar.md5
- Put your phone in download mode (turn off phone, then hold VolDown+Home+Power to boot - if it asks you to press a button to continue, press the listed button, or run adb reboot download command)
- (USB) Connect the phone to your computer
- Make sure Repartition is NOT checked
- Click the Start button
- Wait for Android to boot
- Done (if it took you more than 30 seconds, you need practise!)

The problem is that by mistake I used a wrong CF-Auto-Root... file and instead of this file CF-Auto-Root-t03g-t03gxx-gtn7100.zip which was designed for Samsung Note 2 I used a file which I was using before for my own phone (Samsung Galaxy S4) CF-Auto-Root-jflte-jfltexx-gti9505.zip
Result 1: The rooting process got frozen and I had to disconnect the USB cable connecting the phone with the computer.
Result 2: Black screen, I couldn't boot the phone.
Next, I used the same rooting method but with the correct CF-Auto-Root... file.
Result 3: Bootloop. The phone boots up when I press the power button but when I see the first screen with a white "Samsung Note 2" on a black background, the phone reboots again and the process repeats itself for ever.
Result 4: I can't boot the phone in recovery mode. When I press the Volume Up+Power+Home buttons, the phone reboots and keeps rebooting instead of going into recovery mode.
Result 5: The USB Debugging Mode was not activated before rooting. Since I can't turn on the phone I can't activate the mode now. All solutions to my problem that I've seen require having USB Debugging Mode activated.
Could anyone help me and suggest what to do, please?
I don't know much about how mobile phone works but I can follow instructions if I know what to do.
I rooted my own mobile phone and installed Cyanogenmod successfully. I wanted to do the same with my friend's phone who was fed up with bloated and slow manufacturer's firmware.
I hope you can help me. Thank you.

I really don't know why so many users try to root before flashing a custom rom -> it is simply useless and as shown in this example dangerous, when a false root method or file is chosen.
You need:
1. Custom recovery, flash through ODIN, I think latest TWRP will do the job
2. Flash your desired custom rom through above recovery, (if needed: GApps also)
3. Flash SuperSu if needed (read in OP of that rom) done
If number 1 won't work, you got to flash firmware from sammobile first using ODIN
and then take steps 1, 2, 3

Hi AndroidWizzard!
Thank you very much for your quick reply.
I've done everything as you advised me to and... it worked!
Firstly, I installed TWRP, I wiped all files on the phone, downloaded Cyanogenmod to external SD card, installed Cyanogenmod through TWRP and all done! I also installed the minimum version of Gapps and it's all I need.
Thank you SO much for your help. twdeim which

As I said, everything I mentioned before went fine but there is one problem. The system doesn't detect the network as if the SIM card wasn't inserted. I double checked everything and I have no idea what that is.
I installed CyanogenMod version 11-20140715-NIGHTLY-n7100 with android version4.4.4.
I would be very grateful for any suggestions.
Many thanks!

The problem originated from the fact that my IMEI got lost somewhere during failed rooting/flashing. I've flashed with the stock firmware which retrieved my IMEI and the phone connected to the network as usual. After the phone was brought back to the fully operational state, I used CyanogenMod installer for Mac and I successfully installed CM, and it works like a dream.
I hope it will help. Good luck!

Just copy of my posts in another thread as this one is more relevant to my problem I think:
Good afternoon gents and girls, I have a bit strange problem wonder if anyone can get a bit of light on it. My Mrs's GT-7100 one day was stuck on boot up screen. I thought is was corrupt tried to do factory reset. Didn't work out read about is decided to flash it with a different official ROM for that installed twrp-3.0.2-0-t03g.img.tar and was trying to do a lot of different things within TWRP mode. As I'm not familiar with flashing process I guess didn't do it properly BUT! While doing it all over sudden I realised that the phone is actually working while connected to external power it shows charge and goes upto 100% but as as soon as it disconnected from main power source it starts to reboot constantly again stuck at the same boot screen again, till reconnected to power source again, then goes in to fool boot and functions properly making and receiving phone calls. The charge shown on the battery drops from 100% to 4-7% in a matter of the boot up time which is say 5-10 seconds.
Tested by multimeter battery shows 4.32V. I can't test battery under load, but will endeavor to do so by a test light. I have a bit strange problem wonder if anyone can get a bit of light on it.
So any thoughts?
I suspect the battery is not the issue. I have 2 external banks which are holding the charge to keep running Galaxy 3 8.0 up to 2-3 hours in use. Both of them are 5.2V 1A and having GT-7100 connected to them doesn't help to boot up the phone. Olso 5V 0,5A charger of Bluebery either, only Samsung 2A charger gets the GT-7100 back to fanctioning mode. When phone is booted up it shows
The ROM Version it is N7100XXUFND3,

If you follow the instructions for method 2, and repeatedly do it a few times, you can succeed. The important thing is to follow the instructions strictly, however silly they may look like.

I did several times, double checking all steps, still boot loop. After apply the method 2 , is doing a boot loop. Than I tried to apply again method 2 I have the successful download with green ...than I go in recovery and flash over adb sideload oos 3.2.8 ...than I start , no more boot loop, but after Oneplus logo goes into black screen with a withe stable notification led turned on ....I left over night ... But it keep staying like that until I force to power off by pressing and holding power button( after I want to turn off i cannot only going into bootloader and from there I choose power of, because is automatically turning on if I press and hold only the power button in order to turn off the device).

The bootloader and baseband versions were missing when i bought the phone new and are still blank today after flashing a few ROMs and Recoveries/Firmware and modems. So that is not an issue.
Are you downloading the correct files?

RMA'd it to a service center for repair, after two tech support calls. They actually told me that they couldn't repair it due to "water damage." Funny thing is, that phone was never dropped in or on anything, let alone in WATER. Then to add insult to injury they refused to send it back to me stating that I had to pay for return shipping. My wife got on the phone with them and by the end of the phone call they said that they would send it back for free. HAHA. So I bought a Oneplus 3 after that whole ordeal. All the while the Oneplus X sat in the box on my desk for about 5 months. Last week I decided to pick it up and tinker with it some more. I scoured the net trying to find any other programs or solutions that I hadn't tried prior to sending it off. I came across somethings that I hadn't seen before. https://forum.xda-developers.com/oneplus-x/help/fastboot-mode-available-stuck-kindly-t3387918. http://rootmygalaxy.net/oneplus-x-s...w.pickmod.com/rom/4187/coloros-for-oneplus-x/. Ended up flashing Color OS via msm tool. Wouldn't load OS, but i didn't end up with a black screen and white LED, it just sat there. So right after I flashed Color OS, i Flashed the mini unbrick tool by Naman, and BOOM it booted into OS. Hope this helps.

I want to root my ZE551ML but I don't know what to do pls help.

I tried to root my phone last night, but I stop midway of the process because of some problems like "phone not turning on with no vibrate at all when I restart after its stuck to inverted white screen, when I luckily turn it back on but it bootloops".
Heres the details:
I run unlock.bat then after its done it reboots with inverted white screen with logo then I run restore.bat and after it restart there is no sign of warning "failed verification" until it fully loads up, I go back to fastboot again to flash TWRP after running twrp.bat it says "flash succesfully" and the program closed by itself, then I go to recovery mode after rebooting I saw android error just like how it use to be. I press power button + volume up then release the volume up then I see the stock recovery (which it should be TWRP since I've done flashing it).
I think that my bootloader is still locked since there's no warning display of "failed verification". So I repeat the steps again after running unlock.bat, it reboots and the screen is inverted but it's stuck up to white logo, I waited for a while but nothing happens so I tried to reboot my phone "holding power button (power off)" when power on, it wont turn on, no vibration just a sound on laptop "connected sound and disconnected sound" I tried to power it on many times but still no luck I got panicked, jittery walking back and forth :crying:. Then I disconnect the usb cable and I tried to turn it on and suddenly I feel the vibration on my phone then it boots up but still stuck in white screen then it restart after keeping it for too long (while watching videos related to my problem)...
then my friend here said "ohh it bootloop" he read the instruction and he said to try this
"FAQ 1. Stuck at white screen with asus logo?
Sol. a) White screen means you are unlocked (action of unlock.bat), so you may give a try to restore.bat in fastboot mode."
and it solve my problem my phone is working again ... But I want to continue to root it but I'm afraid which steps I should go next, I still don't see the warning "failed verification" after my phone boots up and works again... I need HELP thank you
I also got question: is my bootloader unlock since it inverted white screen? or it still locked since there no sign of warning "failed verification"?

model number: ASUS_Z00AD
android version: 6.0.1
software information: WW_4.21.40.223_20161216
P.S my phone is back on working state.
I just don't know if I can proceed to root after the incident. I don't know, I just want to make sure that my bootloader is still unlocked after what I've done (it did white screen with black asus logo) or.... it doesn't unlocked at all since I don't see this warning "your device has failed verification and may not work properly." (I've attach screenshot from the video tutorial)
I tried to manualy check if my bootloader is really on unlock state but I can't using these methods
method 1: on device’s dialer dial *#*#7378423#*#* (failed)
method 2: fastboot oem device-info (failed)
my recovery it still on stock recovery even after I flash twrp
btw guide source: https://forum.xda-developers.com/zenfone2/general/root-install-xposed-marshmallow-6-0-1-t3456443
Q: should I still continue to flash twrp until it install?

Theres 2 bootloader unlock tools in general section , one is automatic

Read this from start to finish before doing anything.. also have on another device to refer to as you are doing the steps also download the ROM and gapps you want and put on SD card before you start even if you have to download them and move them from PC to SD card. https://plus.google.com/113955136844726294013/posts/aLJdNZN3g8q

I've haven't fully read the instruction maybe tomorrow I will read it.
I just downloaded the files early and look into it... it seems like the versions are kinda latest (I don't know much about the droidboot ver. but I just look at the number on it "the higher the latest /heh") also the twrp is 3.0.3.
the ones that I used are all in package and it was 3.0.2 so I kinda go for the link you gave me
Thanks :good:

Galaxy S20 Ultra stuck in Recovery Mode after failed Smwart Switch Update

Hi guys,
I attached my brand new Galaxy S20 Ultra to my PC and started Smart Switch today. The Software showed an update for my device so I downloaded it and started the update process. Unfortunately, Smart Switch got stuck during the update process at 68%. Nothing happened, cables and all still attached. It just didn't proceed any further for hours.
I decided to take the path of stopping the process, using the key combination shown on my device. It now said, recover your device software with Smart Switch Emergency recovery function. I started this and guess what: it also stopped at 68%.
I "rebooted" the device (volume down + power for approx. 10 seconds) and it starts again in recovery mode.
I manually filled in the recovery code and it seemed like Smart Switch was downloading the OS again. Started the recovery process and it is stuck at 68% again.
Now I am just super afraid that I bricked the device by using Samsungs original software.
Anyone her to help or have similar experiences?
Thanks for any advice on how to proceed.
Julius

What exactly were you trying to do? I mean normally you hook up old phone and use smart switch to update new phone. So why was you connected to a PC? It does sound like you bricked it.
So now you probably need to flash the ROM.

I read that smart switch is a good and valid source to check for updates. I never thought that an official Samsung software can be so bad at something so basic, resulting in bricking my phone...

Stop using smart switch to update your phone. You haven't hard bricked it because you still have recovery. It's called a soft brick. Download Odin 13.3_3B from here on xda. Do not use the 13.4 because it's suspected to have a fishy call back to a server from a dll that's in the program folder. Download the atch firmware for your model from sammobile or get it in this s20 ultra forum. You should be able to flash the new firmware.

Thanks @freebee269. Does flashing the firmware with Odin void my warranty or does this only count for rooting devices? (Sorry for stupid questions)

Odin uses official firmware from Samsung so no warranty voided.

What kind of USB Port did you use?
Try again using a USB 2.0 port, Samsung always had problems with it's software and USB 3.0 ports.
Use USB 2.0 and try again.

Hi guys, i have a similar problem as (xReem).
Attached my GT SM-T515/10.1 tab to smart switch where the software was unable to recognise my device!? Was advised to use the Emergency Code function but i have no code due to backing up my data to sd card! I have Magisk and TWRP installed where my device was working beforehand, but since attaching to smart switch, my device is now totally "dysfunctional"!!!
Error message as follows...
...An error as occurred while updating the software. Use the Emergency Recovery function in the Smart Switch PC software. ...
Like i sad, i have no code!!!
I am able to get to the device unlock choice screen and if i choose to restart, my device always boots to the Smart Switch Emergency Code screen?! If i choose the device unlock or download screens, both screens are accessible! Tried to flash my original firmware (BTU-T515XXU3ASK5-20191224095700) using Odin3_v3.14.1 and twrp-3.3.1-6-T515XXU3ASK5-20200215 with no joy (Fail!)
Although i'm totally @"#$%* off about this, as its a new device, i am also curious if someone has ever cracked this... 'Smart Switch No Code' problem before. Hmm...
Anyways, any help appriciated...
Oh! Cannot access recovery at all...
Any help appriciated.

Did you ever get things working ? If not, when you flashed with Odin - did you use the PATCHED Version ? THis is necessary when flashing firmware via Odin on the S20 Ultra.....
You can download Odin 3.14.1_3b here: https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
Be sure to download the PATCHED version of 3.14.1_3b (it is located as an attached file at the bottom of the first post in the OP at the link above. Hope this helps.

No, to answer your first question, and yes used the patched version of Odin you state but with no joy.
(would another version of Odin be better for my device model?)
I just need to find a way to flash the original stock recovery. Having the TWRP installed as mentioned earlier is blocking my path, and I have now tripped knox! So no more options available to access the unlock oem screen. Now frp is off, oem is on!
Also, I was wondering if anyone had thought about a totally updated version of the old "ALL IN ONE TOOL" which was available for some earlier makes of phone devices? I think due to manufacturers security upgrades of today's phones we could all do with something like this?
I heard you can do a NAND/Reset wipe via the Odin options screen which would allow you to install a new rom???
Oh, my predicament was based on Julius's post, not xReem. Sorry for the confusion.

Sorry for your troubles - wish I could help you but you have done everything I would have tried. Maybe, if you haven't already done this - leave the phone on until the battery runs out completely. Then, recharge the phone for a while so the battery has some juice again and then get the phone back into download mode by pressing volume up and volume down at the same time - then plug in the USB - it shoul.d launch into download mode again - then try flashing again with the patched odin.
If you have already done this - then I don't know how what else to suggest.
I wish you luck and hope you are able to get things working again.

Hey Julius, did you get your phone to work. I am having the same issue.
Update:
I am good now. I was using the thunderbolt cable that came with the phone and update would get stuck at the same point everything with odin 3.13 and 3.14.
I used a USB 3 to thunderbolt cable that I had from an older phone and it work.
What I used:
Windows 10 x64 1909
USB 3 to thunderbolt cable
USB driver downloaded from Samsung support. I think it is the same driver that comes with smart switch because when I installed it, it prompted
to reinstall driver.
Odin3 v3.13.3_3B_PatcheD from here https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572. ( I think 3.14 will work too.
I really think the cable was the only problem)
Firmware downloaded with SamFirm

Open Odin as administrator and if using a stock AP file always use the HOME-CSC of the same firmware in CSC slot. Sometimes Odin plays the fool and gets stuck.

Wow! This nearly worked!!!
Managed to get a (((PASS))) on Odin and my tab actually rebooted into the Samsung logo!!!
Soon after this though tab immediately Boots back into download mode??? Tried the same steps but without any progress???
I feel I'm close to cracking this but need some more advice on how to build on such "progress"!?
Many thanks for your advice...

Try with all slots filled but with CSC file not HOME-CSC. That may help as it flashes pit file to factory reset

(((SUCCESS)))!!! :laugh::laugh::laugh:
Done what you suggested by waiting until my battery ran out!
I downloaded a different software version and as soon as I plugged my tab into my PC with USB, i flashed the new software with no problems!!!
Flashed TWRP, Magisk and Multidisabler problemless the same!
The lesson learnt here...
...(ONLY FOR THOSE WHO KNOW WHAT THEY ARE DOING)...
...is to probably only have 30% battery when flashing!!! This way you won't have to wait weeks for such a large capacity battery to run down, like I did!
I knew I'd crack it!
