Hi folks,
yesterday my Nexus 4 hit the ground and the front glass just bursted. Touch is not working anymore and the screen is locked (only slide to unlock, no pin or gesture). I can connect it to my PC and can access the internal storage, so backing up images, music, etc. is not a problem.
I have some apps installed of which I want to transfer the app data to my new phone. Debugging is enabled so I thought, well that'll be easy just run adb backup. Thought so... As adb backup requires a user action when it comes to entering the password I'm doomed
Does anybody has an idea or experienced the same problem on how I can get adb backup to work without being able to use the touch screen?
I'm not limited to adb backup but as my phone is not rooted I assume there are not a lot possibilities besides.
Thanks a lot for your help.

Do you have a custom recovery? Try flashing a non-touch one. Adb should work from within it.

As I wrote, my phone is NOT rooted nor unlocked, so no custom recovery. Or do I get something wrong there?

Your outta luck it seems then... If its that important to you you could buy a replacement screen for the n4... Get your data and sell it and get the money you spent in the screen back.

If the apps that u need data are on sdcard(their datas)then u just do adb pull /sdcard c:\sdbackup with phone on.
if not then:
@calex3141 :
1ST: IM NOT RESPONSABLE FOR ANY DAMAGE / FAIL WHILE DOING THIS METHOD, I TESTED ON MY FRIEND´S N4 BUT I CANT GUARANTEE THAT WILL WORK ON EVERY NEXUS (INCLUDING YOURS), USE AT YOUR OWN RISK.
2ND: DO NOT CRY IF U CANT GET BACK THE FILES IF SOMETHING FAIL. YOU COULD JUST BUY SCREEN REPLACEMENT OR GET A JTAG DUMP
3RD: do carefuly. if you are nervous calm down b4 doing this. one single command and u can format the nand so be careful.
4TH: I hope it Works for u .
5TH: u need to have adb seted up and also drivers. if you dont know how, search google(for drivers).
for adb just install minimal adb and fastboot
6TH: its recomended to test to see if cygwin(u will know what it is in a moment) is working (do some commands on it, like cd .. (to go back)or ls (list files) )
7TH: if u have any errors contact me asap and i will try to help you
LETS GO:
unlock the bootloader: (type in cmd prompt, fastboot oem unlock, and follow instructions on phone)(DO THE MANUAL WAY, DO NOT USE TOOLKITS, KEEP READING TO KNOW WHY)(it will say that u will loose files, but it actualy dosent format, it just change the 1st´s block of userdata partition to make it unmountable normally,thats why toolkits do fastboot format userdata after unlock.and tutorials say to format data in STOCk recovery, since custom ones dosent format, just delete everything except sdcard)
(do not format anything, even on stock recovery)
flash multirom recovery:http://d-h.st/pzv (Thanks@tassadar for his great work)(the only that i use, so i cant tell others)
then do this
http://forum.xda-developers.com/showthread.php?t=1994705
(instead of doing it with phone on, just do on recovery,adb is enabled on it)
This method here seemed pretty straightforward to upgrade to Nougat: https://forum.xda-developers.com/axon-7/development/edl-emergency-dl-mode-twrp-unlock-t3553514
I was already unlocked so I figured I just need to flash the "Full" package then the "TWRP" package. TWRP is working, the bootloader still shows as unlocked in fastboot mode, but trying to boot just shows a Linux penguin and nothing else!
I just cleared everything in TWRP to see if that was somehow the issue then reboot, and TWRP says no OS installed! HOW?!
All this happened because I'm unclear on everything, and instead of a yes/no answer I get mocked. Someone please help.
Can you Boot in Fastboot?
When yes . load a Original Firmware update.zip and extract recovery.img from this . Do the recovery.img in Minimal adb and fastboot , open a command windows .
Type: fastboot flash recovery recovery.img ,before this boot the phone in fastboot mode.
After the flash recovery ,boot the phone in the recovery with Volume down (tick them 1 or two times ) reboot ist with power.
Put a SD Card in the Phone with the update zip in root folder of the SD Card.
In recovery tick with Volume down to the Point update via SD Card and wait the Process ist finished.

I have access to fastboot mode. However I'm still confused as to what is going on.
At least I've figured out where it goes wrong, at the TWRP step. The "no OS detected" made no sense so I tried flashing using the same method but just the "Full" package first. It eventually does boot and it appears Android 7 is working.
The bootloader shows as unlocked. However when I install the TWRP package after, TWRP is restored but then the phone is bricked and TWRP says no OS detected. I'm not sure if this is because I clicked "allow modifications" and if so why that causes it to go wrong and what I missed. I tried flashing TWRP manually using fastboot mode in case something was wrong with that EDL package, and the result is the same, after installing TWRP and clicking allow modifications the OS is no longer detected.
What am I missing? I must have missed a step.
ok. go to twrp and format data to ext 4 then flash new and restart.

When go to "Format Data", enter yes to allow it, it fails and says:
"mkfs.f2fs -t 0 /dev/block/sda9 process ended with
ERROR: 255
Unable to wipe Data.
Unable to format to remove encryption
Upadting partition details...
Failed to mount '/data' (device or resource busy)
... done"
Even if that went through I'm unsure what you mean flash new? Flash a new what?
When I enter repair/change it says the file system is ext4 anyway.
Well I tried starting at that point again since I didn't allow modifications in TWRP this time, and it actually booted Android but then asks for a password... what?
So something about allowing modifications in TWRP seems to be the culprit, but then I'm unsure why it would ask for a password to start the device when it boots after, it's obviously encrypted.
Flashing back to the "Full" package yet again to restore it working.
Edit: I thought double posts would be auto-merged...
Edit 2: "Format Data" left my device encrypted and the only way around it was a factory reset!
Edit 3: I read over the instructions in the TWRP thread again and I think I've found what I missed. If I don't update this thread again by tomorrow that means I've figured it out and everything should be fine.
Thank you everyone who tried to help.
Can you please give me instructions of what you did to upgrade to Nougat, I'm like you when started the upgrade on B29 Unlocked and rooted. I like the way of EDL process but It is a little vague and I don't want to brick my phone. Thanks in advance.

Hi...I ran into your original issue and I believe it's related to dm-verify. For anyone that runs into this again, try flashing a dm-verify disabling zip and see if it'll boot again. This was the only way I could get the phone to boot after upgrading to nougat...not sure why this is an issue though as (I think) I had the stock bootstack in place along with stock System files.
Here is a link to the dm-verify disabling tool I used:

I used the EDL method in the end. Part of the reason I set that up to begin with was just in case in the future I brick something, I'll have the ability to recover from anything prepared.
The step I missed which resulted in a brick was installing SuperSU (since I wanted root anyway, or you can disable dm-verity as the other fellow posted here) after allowing TWRP to be able to do modifications. Then I ended up with more bricks because I used SuperSU 2.79-SR2 and SR3, I thought it was fine since SR2 is what I was using with Marshmallow, apparently not, you have to use a non-SR version of 2.79 with Nougat.
So in summary, from EDL mode I:
1 - Installed the "Full" EDL package.
2 - Installed the "TWRP" EDL package, or you can flash it from Fastboot mode which might be more convenient since you'll have to restart EDL mode after flashing the first package to get it working/ready to flash in EDL mode again.
3 - Gave TWRP permission to do modifications and immediately (without rebooting/starting which would result in a brick) installed SuperSU 2.79 (non-SR), then rebooted (this could take a few mins as it says and can bootloop a few times).
If you said no to permissions for SuperSU and it's not giving you the option again you can reflash SuperSU then reboot to bootloader then reboot to recovery, that should make it show the option again. And in case you're not aware, to make changes to system files and such permanent when you have root, you have to enter a command in TWRP's terminal emulator or ADB shell. I think it was "reboot disemmcwp", it may need "SU" in front if you're doing it through an ADB shell in Windows, I'm not sure. Not quotes of course. Search the forums to find out for sure, it had to be in a guide somewhere.
Edit: Just to be clear, for step 2, when I said "or you can flash it from Fastboot" I meant TWRP in general, not the TWRP EDL package.

Many thanks body, As you said using EDL mode is great to unbrake your phone from any state plus it reminds me with Odin that's why I like this way it's very simple, but as you know this is not Samsung phone and it has so many complications. ???

No problem. I threw in an edit to my last post to clarify point 2 in case you thought I meant you can flash the EDL package from Fastboot mode, I meant TWRP in general. In case you forgot the command to use in the ADB shell it's "fastboot flash recovery FileName.img" (twrp-3.0.4-1-ailsa_ii.img in my case).
If you already had the "reboot disemmcwp"/"SU reboot disemmcwp" step done you don't need to do it again.
And just some general information for you regarding my experience with Nougat so far:
1 - When I started it I selected Canadian English as my language. This apparently disables ZTE voice functions, or Nougat is missing it in general. It's missing from the menus and when I hold the back key it said "Only English and Spanish supported". Piss poorly done as usual, ZTE, since the pronunciation of Canadian and American English is nearly identical with very few exceptions, might as well have left American English enabled for voice commands. So I went into the menu and selected just "English" as my system language, and now the option to set Canadian English is missing entirely, and voice functions are still missing. Holding the back key just results in nothing now instead of the "Only English and Spanish supported" message. So I'm saying I don't know if ZTE voice functions are still there, someone else can answer this, or I guess you'll find out.
2 - Google's Timely alarm app (and possibly other alarms) still don't work properly and will be off by several minutes, so I'm stuck using the default sucky clock app until I find something else that works.
3 - The default apps are all still the exact same trash. If you really want to use the AKM "32 bit" (truncated to 16 bit output) Hi-Fi DAC and amp you're still stuck with the garbage laggy default music app, which now has some sort of bonus lag/stutter. People claiming that you can use the DAC with something like PowerAmp are sadly mistaken, that sounds so different and lower quality than when using the stock music app and even says it's using the SD 820's 24 bit DAC when set to Hi-Fi output. There's even a ridiculous rumour going around that the Axon 7 doesn't have the SD 820's DAC which is retarded, ZTE can't pick and choose components of SoCs supplied by Qualcomm, they just buy some of their stock of what's already made. It's definitely in there, whether or not it's enabled is another story.
4 - Battery life is worse, this is at least partly because there is no Xposed support for Nougat yet so I can't enable the Greenify module to allow really aggressive dozing and dozing on the go (which I thought Nougat was supposed to support?). It could also be partly due to my battery being rapidly degraded from Daydream mode being a firey hell inferno. It heated my battery up to 48C and over 42C in other cases even with my best efforts to keep it cool by enabling Ultra Power Saving Mode (which Daydream may be overriding) and shoving in aluminium foil to act as a heatsink. All phones from reports so far overheat horribly when using Daydream, especially the Pixel XL. It's not surprising that the Axon 7 rapidly overheats as well considering it literally uses the battery as a heatsink; a heatpipe carries heat from the SoC to the battery. I would have not bought the A7 if I knew this.
Edit: I forgot -
5 - ZTE locker no longer allows browsing all of their past content, only what they allow per day, which so far for me has only been the same crap and never anything new. Too bad, I liked some of their old content, though it was all 1080p and not 1440p. Oh well.

Omg bro, To be honest I hate the software experience on that phone. It is the only thing that turning me off from it. I played a little with my brother's S7 edge the other day, and believe me the software experience is extraordinary. However I noticed that the S7 edge overheats a lot too without even using the daydream. In my opinion I think Axon 7 lacks in hardware wise a bigger battery and the support of the new RCS messaging feature, and in software wise a whole new developed system.
I'm not sure exactly what I did wrong, but in the process of trying to root my B15 A2017U, it ended up in a state of, I'm guessing, permanent EDL mode. The phone gives absolutely no response to any buttons or attempts to boot it (no vibration, no lights, just a black screen, whether I try to boot normally, boot to recovery, or boot to EDL), it does show up in device manager as Qualcomm HS-USB QDLoader 9008 (COM10), but adb won't recognise it, and it shows up in MiFlash but any attempt to flash anything results in "cannot receive hello packet", "try to reset status" and eventually "error:The write timed out."
I've been reading through a lot of threads here, but at this point I'm pretty much out of ideas, and I'd really like to have a phone for work in 6 hours. Can anyone help, please?
Not sure how useful it will be, but here's everything I can remember about what I've done just so there's something to go on. First, I tried a few days ago as detailed in this post, and put it aside after that post. Aside from not being able to get to recovery at that point, the phone was working perfectly. Today, seeing the new Axon7Toolkit, I decided to give it a try. I managed to unlock the bootloader and get into TWRP recovery (during the process, it asked me for a decryption password and I hit cancel). I've done a lot of reading and searching since then so I can't recall the exact steps I took after that, but I wiped the device (I didn't change the filesystem or anything) and got errors, and then after seeing the "your device can't be checked for corruption" message I searched and found that I need to mount system, so I did so (not in read-only), and wiped again, this time with no error messages. I can't remember if I did anything else in TWRP aside from looking through the options available. After that, I think what I did was "Flash TWRP and/or root" again in Axon7Toolkit, and I think something went wrong at that point. That's pretty much all I know.

I think you got the "cannot receive hello packet", because your bootloader is locked. Using this method https://forum.xda-developers.com/axon-7/development/axon7tool-flash-backup-boot-recovery-t3514254 to unlock it, then flash twrp, then firmware
The bootloader was unlocked (though it may have been unintentionally re-locked somehow?), and MiFlash works with a locked bootloader, so I don't think that's the issue. Axon7tool also doesn't help, because just like adb it can't find the device.
Now, trying again today, MiFlash is working for some reason. I haven't done anything differently, but I can flash whatever I want with MiFlash now. But it doesn't really make a difference, because the phone is still entirely unresponsive, I can't enter recovery or boot in any way. Any suggestions for what else to try?

Hi, I'm the dev for the toolkit and I think I know what the problem is. Can you go into C:\Axon7Development\Axon7Toolkit\twrp and see what the size of the image is? It may have been a bad download. Either that or there is issues with the latest version of SupersSU if you chose the root option.

Ok so TWRP is definitely not the problem. Can you remember exactly when the problem happened, like after SuperSU was flashed since you mentioned using the Flash TWRP and root option?
I don't remember any specific details, but I'm fairly certain I didn't get to the point of flashing SuperSU. I think the most likely cause is me doing something wrong in TWRP (I was trying to follow vague guides mixed with scattered information throughout various threads), and when I did "Flash TWRP and/or root" after flashing TWRP, I think I got some error messages right away.
One problem I do remember is that the toolkit would sometimes say something like "device not found", but still try to continue whatever it was doing and move on to the next step as if there were no problems. Unfortunately I don't remember exactly when it did that, so I can't give any details on how you could reproduce it.
Hey, I had exactly the same problem. Are you saying miflash is now working (you get success at the end!) ? If so, I don't understand why it wouldn't boot afterwards.
If not, in my case, a computer reboot, switching to MiFlash Beta and switching com ports eventually allowed me to flash successfully B15 full package after 3 hours of cannot receive hello packet. You could always try full B13 (Chinese rom) or other similar packages to see if it makes a difference. You'll be able to revert afterwards.

So you're sure that your problem is not because of my toolkit? Regardless looks like now I have to fix the ADB check

MiFlash does seem to be working, I don't get any errors and it says it flashed successfully. I tried flashing B15 full and fastboot unlock from here, neither allowed the phone to boot.
Any suggestions for specific files to try flashing?

I can't be sure since I don't know exactly what the problem is or how I caused it. All I really have are guesses at this point.

I rebricked myself last night (lol), so I had to reflash full package, from the same link you posted, and here are some notes:
It seemed on first boot that it didn't work: usual three blinks of LED followed by a black screen
Second boot worked (and I now remember that the same thing had happened the first time I bricked my device), but Android asked me for a password even though I had formatted /data
From there, install TWRP via fastboot (and fastboot_unlock prior to that if bootloader is locked, it shouldn't be), format /data using TWRP, reboot, and you should have a working device
Hope it helps!

I don't even get that much, nothing I do gets any response from the phone at all. No LED when trying to boot (including EDL or recovery), no LED when charging, the only indication that the phone isn't perfectly dead is that it shows up in device manager and MiFlash.
You could try not flashing fastboot_unlock right away and booting first instead... This is the only thing we are doing differently, although I don't see how it could have an impact.
You could also try flashing this EDL package (B13) instead and flash your device specific bootstack afterwards.
Still no luck with anything I try to flash in MiFlash. But I tried reinstalling drivers with Zadig, and axon7tool is working this time. Trying to read gpt works fine, but if I try to read/write boot or recovery, I get "W: bad lba in partition entry 26" and "Cannot find partition boot"/"Cannot find partition recovery". I tried writing TWRP and a couple stock boot/recovery images despite the error, still no change.
Do those error messages give any new information that might be helpful?
Try miflash firmware from offical:
https://www.zteusa.com/axon-7#support
Not sure if this will help you but that miflash utility is a piece of ******** to work with I found.
When extracting the zip files there will usually be 2 folders in them, one is meta-something and the other one has the full name of the zip file, you have to select the full name one beside the meta folder not the parent folder.
Also Sometimes you need to hold all the buttons again and "restart" edl mode before the "hello packet" issues go away.

Thank you. This helped me. Why the *$*# can't the program just pick the zip file, or tell you which folder to pick? Until I found your post, I had no idea which folder to pick.
Thanks!!!

Ok guys, new here and I've done a bit of reading on this already. From what I gather, the S7 Edge is difficult if not impossible to unlock without a factory reset. Here's the issue.
This phone belongs to my friend's husband who was severely injured in an accident at work. He's in a coma and probably won't survive. He was severely burned over 90% of his body with chemicals and he has no fingerprints to unlock the fingerprint scanner. In addition, his wife doesn't know his password, so I figured I'd see if I could do anything for her. I tried the Dr. Fone program, but it's apparently incompatible with the S7 Edge. He keeps getting texts and messages and we can't check them. The phone is also set for a daily alarm at 1:30 AM, and apparently you can't power it down without the lock code either. Ideally, I'd like to either gain access for her or at least extract what data we can from the thing before factory resetting it. It would also be nice to power it down so that it doesn't keep putting out an alarm every night in the middle of the night. All his contacts with his family are inconveniently stored in the phone as well. It's kind of a worst case scenario.
Any assistance or recommendations for a course of action for this situation would be fantastic. I don't have any other information on the device itself other than that it's running on Freedom Mobile's network in Ontario, Canada. They've said they can factory reset it for her, but we were trying to avoid that and get any contacts or messages from his phone if possible.
Thanks in advance for any help! I know it's a long shot!
Edit: I managed to power down the phone with the Power Button/Volume Down trick after about 9 tries, so at least the alarm won't go off. Other than that, no luck.
Unique situation? More like fked up situation.
Anyways I am assuming its a completely stock phone with USB debugging turned off. Hope its not carrier locked, if yes then here are the steps:
1. Flash Custom Recovery on the Phone using Odin
2. Use aroma file manager from the Recovery, you need to download it separately, put it on its SD card.
3. Now using aroma file manager navigate to Data Folder and then; System Folder and find “gesture.key” or “password.key” for pattern lock or password lock respectively.
4. Delete those any password related file and reboot. It should be unlocked now.
Thanks VERY much, UnNaMeD__!!!
I'm looking at Odin and the Recovery firmware right now. Is there a recommended version? I see TWRP and CWM, but primarily TWRP mentioned, and it looks like the .tar files are easy to find. I'm pretty new to this type of mod and I don't want to brick the phone, I know it's a risk. I'm looking at faqs on theandroidsoul and the cyanogenmods forum which seem quite thorough. Apparently I can't post the links as I'm a new user here....seems fair I suppose, especially considering the forum content.
My friend's husband didn't have a microSD card in (just checked), but I can toss a spare one of mine in for Aroma, which I found. I probably need for format it for FAT32, not NTFS though? Is there any way to tell if it's carrier locked? It's from a small phone company, not one of the bigger guys. I'm going to wait until I hear back to get started on this, as I'm decent with Windows based systems, but unfamiliar with the nuances of modding Android. I use a stock Sony XZ Premium myself.
Again, thanks very much! I've got some hope we can get in touch with his family now!

Use odin 3.13 the latest
Then download twrp recovery 3.2.2.0 tar file for hero2lte the latest.
Boot your phone into odin mode by restarting your phone while holding power home button and vol down. When your reach the confirmation screen press OK.
Open odin and put the tar file in the ap slot and click the ap box and hit start to begin flashing.
Now restart ur phone by holding power home and vol down then immediately hold power home vol up to reach custom recovery.
Edit I just tested this myself
Flash the zip file from this thread no need to go looking for files in system.
https://forum.xda-developers.com/showthread.php?t=2780696
Should remove password pin or pattern.
To check if it's network locked just look at the back of your phone if it says 935u or Verizon wireless or 935W8 then the phone is unlocked for different networks.

Just look at back of your phone and tell me its model, Like G935F. I will give you the correct recovery file. And recoveries have option to enable storage too so you can access data from computer. But to be honest it never worked for me. You could also give it a try before doing other steps.
You could contact on PM, or even better I could also help you over whatsapp if you wish.
And I never heard that you could brick phone by flashing recovery, maybe only if you flash incorrectly. A bad recovery will make recovery useless, but phone would still boot. Thats my experience.
I have broken password before of a Mediatek device. If you want I could try it on my own S7 Edge too to be 100% sure.
I'll send you a PM as well, but I just checked and it's a G935W8. Sorry for the delay, I work shift work and I'm pretty busy. I'm going to work on the phone on the weekend. I don't have Whatsapp currently, but I can get it. Thanks again for your kindly assistance!

Hey alright no problem.
Download TWRP for G935W8 from official TWRP website:
https://teamw.in/samsung/samsunggalaxys7edge.html
You can follow some instructions from this thread regarding flashing:
https://forum.xda-developers.com/s7...overy-official-twrp-hero2lte-3-0-0-0-t3334084
Flashing TWRP might cause your phone to not boot. You will need to download dm-verity disabler from the thread above.
So download TWRP, Aroma file manager, dm-verity bypass, and zip file to disable pass that the other user posted: https://forum.xda-developers.com/showthread.php?t=2780696
Download all these files and put aroma file manager, dm-verity bypass and that password zip file bypass on your SD.
Make sure auto reboot is disabled in odin, follow instruction in thread about how to install twrp. If the auto reboot is disabled, phone will just remain at the same screen, so after the flashing is done from odin. You need to force reboot on your phone (volume down + power button for few seconds), just when the screen goes off, you need to immediately press recovery button combination (vol up + home + power). Here once you enter TWRP recovery see if you can enable MTP and trasnfer data to PC, if not, goto install zip and try password bypass zip file. If it works file then ok and proceed to install dm-verity bypass file and reboot your phone. If that zip doesn't works. You need to go to same install zip file option and now install aroma file manager. From there delete the password files that I told you about earlier, flash dm-verity and reboot again.
Thats it, if get confused about a step, tell me.
Well, I attempted to install TWRP through the latest version of Odin, but it didn't work. The error message I got in Recovery/Download mode was:
"Custom Binary (RECOVERY) Blocked By FRP Lock."
I looked that up online and apparently to install TWRP, I need to remove the FRP lock. I found a program called RealTerm which can supposedly bypass the FRP lock, but it doesn't seem to be connecting to the locked phone and it's not exactly user friendly.
Am I missing something here? Or is there no way to bypass the FRP lock on the unit?
My phone suddenly had a momentary display malfunction (some of the text on the screen just turned into garbled pixels) and then entered into a boot loop. I didn't make any changes or updates to the phone recently. It no longer boots normally - just the Samsung logo and some of the Verizon logo animation, then it reboots and starts again. How do I pull my user data off (photos mainly) before trying a factory reset? The phone is totally stock. I haven't unlocked it, rooted it, or installed any custom recovery/ROM/bootloader/whatever. (I sound like I don't know what I'm talking about because I don't, haha.) The touchscreen is fully functional. I'm sure this has been covered here before, but I haven't found anything that totally explains how to do this in this particular situation, so I'd really appreciate any help anyone can provide.
The only time I can get the phone to show up under adb devices is when I boot it in recovery mode and select "Apply update from ADB". But it says "sideload" next to it in adb devices, and the push, pull, and shell commands return errors. I've read that this is normal. Wiping the cache partition didn't solve the boot loop problem.
If it helps, this is what the top of the recovery screen displays:
Android Recovery
Verizon/heroqltevzw/heroqltevzw
8.0.0/R16NW/G930VVRSBCTC1
user/release-keys
I'm no Android expert, clearly. I've heard it mentioned that I need to install a custom recovery in order for this to be possible. To be clear, I want to make sure I don't erase the user data before I have a chance to pull it off the phone. These are the questions that I still have after reading information elsewhere (some of which I'm just asking out of an abundance of caution):
Is it correct that I need to install a custom recovery before I can pull this data off the phone?
Do I need to have it unlocked/rooted/anything else in order to be able to install a custom recovery? Or is there anything else I should do before installing it?
Which custom recovery should I install?
Do I need a custom ROM, if that's a different thing?
Do I need a custom...bootloader, if that's also a different thing?
Should I use Odin or Samsung Smart Switch to install the custom recovery?
(Extra credit: Does it sound from my description of how the boot loop started that this phone has hardware problems and should be replaced ASAP?)
Thank you so much for any help you can provide! Any extra information beyond my questions will be very much appreciated, too, of course. You guys never cease to impress.
You have a B version bootloader like me, and so far no root/custom recovery has been made for our versions of bootloaders. If I were you, I would check if you had maybe like a previous backup, and if Google made an automatic backup of your apps and photos? If you didn't use a 3rd party backup, and if you don't want to wait, you might lose some files. I also think you might be able to flash a certain part of stock firmware to get your phone to boot again, but I'm not sure
Also, if you don't care about files that can't be get through automatic backups, might as well flash a whole stock firmware, which as far as I know, may be the easiest way to get out of one.
Please correct me if I'm wrong
Also to answer your bullet points:
1. I'm not sure if you need a custom recovery, but from my experience from a Verizon s5, that's probably a yes.
2. Since this is Verizon, you would need to unlock your bootloader in order to install a custom recovery, which in where I posted my first reply, the B version of the bootloader is still locked down without any known way to unlock it. You and me are stuck with this, as I also have the B version.
3. If the heavens line up and you somehow unlock the bootloader, try to flash a recovery Called TWRP under the name "Herolqte" (that's what I think). If that doesn't work, try to find one that works with the phone on XDA. If neither of those show up try to use another custom recovery like CWM.
4. If your trying to recover data on a phone, flashing a custom ROM is probably the last thing you want to do. A custom ROM is a modified version of Android, which may mean you'll have to format your device anyways so this is probably not what you want (even though it would be nice :[ )
5. As in post 2, all you would need to get a custom recovery is to unlock the bootloader. I'm not even sure if you CAN get a custom bootloader, as Odin won't even let me flash a stock bootloader to my phone that is the same exact Version >:[
6. You would need to use Odin if you were trying to flash something to your phone. Smart switch I think WOULD let you back up your device, but you would need to be on the home screen on your phone, which in turn, would probably need you to be out of that bootloop.
7. This is probably a software issue. If you don't care to much about the idea, try flashing some parts of a stock firmware. I was personally in a boot loop 2 days ago, but I flash a stock modem file (I think that was the second file slot from the bottom in Oden) and that got me out, but for some reason wiped my phone clean, and I'm not sure why.
Anyways. Goodluck in recovering your data. Also I'm not sure if a factory reset would even fix a boot loop
