Unable to enter into bootloader mode - Huawei MediaPad, T-Mobile SpringBoard

I own many nexus devices, a heavy terminal user and I know about things like adb, fastboot etc.
This device Huawei mediapad 7 lite is driving me mad, I wanted to install CM 10.1 on it but I am unable to enter into fastboot mode. I have searched enough and tried all the methods like "adb reboot bootloader" and "volume up + power", but no luck at all.
Is there anything that I am missing? I am able to use 'adb' but rebooting into bootloader just power offs the device and sometimes just displays the battery charging icon on screen.
If I try "adb reboot recovery", it enters into recovery mode but within 2 seconds reboots. I somehow need to get into bootloader mode(fastboot mode) so that I can flash recovery and custom rom.
Your help is highly appreciated!
Thanks in advance

Hi,
I am having similar problem for different reasons. I am in a reboot loop and if I try power+volume up I get this: Enter into fastboot mode. You can press POWER key for more than 10 seconds to reboot device.
Power for 10 seconds will reboot and go back to reboot loop, but anything else I try to push does not get me anywhere. In this state the tablet will not show through USB on the computer. I was trying to google how to enter bootloader, but I am not able to find any info plus screenshots. So if you find a solution, I would VERY happy.
I would keep you informed if I find something myself. Here is my post: http://forum.xda-developers.com/showthread.php?p=37646468#post37646468
Good luck.

Then you see on your tablet: Enter into fastboot mode. You can press POWER key for more than 10 seconds to reboot device. - then it means that you are already in fastboot mode. Holding power for 10 s needed to exit from fastboot (to reboot).

Thanks for the reply. Sorry if I sound like a novice, but what can I fo in fastboot mode? The computer does not recognize the device in this fastboot, so I can do anything from computer, and the tablet does not respond to anything pressed while in this mode.So how do I install recovery or do anything sensible? Sorry if I missed something obvious, it is my first Mediapad.

All operations with fastboot should be performed via terminal.

Hello after_silence, any help for me? When I do "adb reboot bootloader", it shuts down and NOTHING comes up on screen. If usb cable is connected, it shows the battery charging symbol. When I do "sudo fastboot devices", nothing comes up. That means I am not entering into fastboot mode. Any other workaround?
Thanks!

Sorry for the simple posting, but the above thread fixed the problem.
The original failure was caused by missing the factory reset after flashing, before unzipping.
Wow , XDA saved the tab for xmas, although the 2 steps flash cust and flash tombstones didn´t
work, it rebooted to an older version just fine!
Then restored backup, I´ll try again after xmas.
Happy Xmas !!

[Q] Boot Loop on LE I/O 10.1 need help!

Hey Guys, could sure use your help... i updated my 10.1 le yesterday and that went thru fine. Later on i was playing and watching youtube and it sent my tablet into a boot loop and i cant seem to fix it. any help would be appreciated thanks in advance.
Mine did the same thing when i was streaming music. Not even Odin brought it back. I used adb to reboot into stock 3e recovery and wipe data/factory reset it, then used Odin to grt back to 3.0.1. Then i just redownloaded the 3.1 update. Hope that helps

right now im having problems with adb listing the devices. adb is installed. it keeps saying that i need some APX drivers???
Drivers are here:
http://www.samsung.com/us/support/owners/product/GT-P7510UWYXAR
I had the same problem. This is what i did. Since I had already rooted my tablet, I already had in my laptop ADB and the driver for the tablet. If you don't have these 2 things, I suggest you go to the development section of this forum, look for the insrltructions on how to root, and download what you need.
I connected my tablet then went into cmd mode (DOS MODE), then typed adb reboot recovery. From there the tablet rebooted into recovery. I then wiped data and cache. Then I rebooted and it went fine, no more bootloop. In settings I noticed that it had reverted back to 3.0.1 so I just did update again. Since then my tablet has been smooth as butter.

For those not too comfortable with ADB, I just installed PDAnet (for the fastboot drivers) and after booting to fastboot (holding power and the volume down button and selecting the USB symbol) I used the "fastboot -w" command in CMD.exe to wipe the device.
Its rather strange that a lot of people are having problems. Mine started after getting an error turning on the WIFI chip. Thank god for Titanium Backup's option to sync with Dropbox. Hope this helps.

THANK YOU!! Your suggestion of installing PDAnet saved me! I was having a hell of a time trying to get the right drivers so my computer would recognize the tablet has an adb device. After installing PDAnet, it was a cinch. Then I reflashed everything, wiped userdata and cache, and rebooted (I followed the instructions found here: http://forum.xda-developers.com/showpost.php?p=14600617&postcount=111) Now my tab is working again and I was getting ready to ship it off to Samsung so they could re-flash it for me.

Obviously I have installed adroid-sdk and download fastboot from HTC page.
I'm one of the lucky ones who has had their I/O tab stuck in a boot loop on 3.1, and after trying the steps below, I am not getting it to work. I know I must be making a stupid mistake somewhere along the line, but essentially,
I downloaded the new image, boot, and recovery files into a directory on my hard drive;
I installed PDAnet;
I entered into fastboot on my GTab and plugged it into my PC;
I can tell that fastboot is now listed as a device (I suspect this means that the drivers are installed correctly and that it is recognizing a fastboot device);
Now when I try to run the fastboot commands suggested, I get 'fastboot' is not recognized as an internal or external command...
Stupid question, but I am supposed to run this command from cmd.exe, right? Any ideas what I am doing wrong so that the fastboot commands are not recognizable? I may need a dumbed down instruction set if there are steps I am missing somewhere...

Edit:
After trying just about everything, I have concluded there are two hurdles I still cannot pass. First, if I fastboot my device, and select the USB icon, my device is appearing in my windows device list. However, I cannot run any fastboot commands in cmd.exe window. Not sure why or what else is needed. Second, I successfully installed SDK and tried to enter recovery mode through ADB, but I cannot find the magic trick to have my device appear in ADB. ODINing back to stock did not make a difference. If I can get past either of these hurdles I am confident I can progress, so any suggestions are appreciated.
fastboot commands never seem to work for me. Always says waiting for device.

Which makes me wonder if I am doing something wrong. I can't even get fastbook command to be recognized. It's as if there is some fastboot software needed so that my pc knows what to do when I type fastboot. I hoped SDK was enough, took a stab with a fastboot.exe from htc I found on another forum, neither worked. How did you get your pc to look for your device from fastboot in the first place?

Hi .. I have the same problems before
I found out that the new ADB has moved the directory to "platform-tools"
This renders the fastboot useless "winapiadb.dll"(or something) file not found pop up window
I got that ridiculous bootloop issue right in the middle of the flight! thought I bought a $$$ junk lol
use the fastboot -w option to recover .. but it resets the whole tablet back to OE (original everything)
Hey guys,
So I have one of the Limited Edition Google IO Galaxy Tab 10.1's and I can't find a more updated thread than this. It seems this problem is isolated or mostly isolated to the Limited Edition tabs?
Anyways, I've read through the thread (as well as many other resources) and I just don't understand what I'm supposed to do to defeat the boot loop problem.
For me, pressing the Power and Volume up button (or Power and Volume down button) doesn't do a thing. The tablet does not respond at all. The only thing other than the boot loop is that I can get it into "upload mode" whatever that is.
This thread doesn't mention upload mode, so I don't know how to proceed. I can't seem to find anything in the manual about this sort of hard reset, nor can I find any information anywhere else.
Also, I've read this thread, and I do not have any familiarity with what the following software projects are: Odin, PDAnet, and APX Drivers. I also have not used the android SDK.
Also, in the third post chris eckman posted a link to some sort of Galaxy Tab drivers on samsung's site, which is now a broken link.
Anyways, while I'm a noob to the XDA community, I am a computer engineer, and I'm confident I won't have any trouble recovering this device. There's just so much conflicting information and alternatives methods that I'm not sure how to proceed.
It seems like a tutorial might exist out there that I have not yet found?
Please use the Q&A Forum for questions Thanks

Ok, well if you are running a "stock" IO bootloader, then you should have fastboot and download modes accessible to you by using the volume down and power button combo.
Have you ever gotten to this menu before? If not, then you just aren't doing it right. Let go of the power button part of this combo once the samsung logo appears, and then you should see two icons appear. If you have an IO bootloader, then you are going to go into fastboot mode, and then use fastboot to get your recovery booted. Once you get CWM booted, you can flash a stock ROM, load up stock recovery and wipe this sucker back to factory, and then fastboot your CWM recovery and install Task650's latest rom and be bootloop free. Let me know if you need further help.
Alright, first things first. Yes, this tablet is 100% stock, and I've done one major Android update, but it was not the one that broke everyone's wireless.
----------
So going step by step:
you should have fastboot and download modes accessible to you by using the volume down and power button combo. Have you ever gotten to this menu before?
So, I did once get to what I believe was the "fastboot" menu. I had four options available to me, the first one was something like "repair boot process" which I selected, because I was having a boot problem. It did nothing, and now I cannot get back to that menu.
I did get to the USB upload screen once by accident, when I was trying to get back to the boot menu, but not knowing what to do at that point. I had to shut it off.
Let go of the power button part of this combo once the samsung logo appears, and then you should see two icons appear.
Which Samsung logo? If I press both the power button and volume up or down, I get nothing. Nothing happens. If I press the power button first and then two seconds later start holding down the volume button, then eventually I get the blue swirly samsung screen. At the end of that, the samsung logo is clear. But waiting a bit longer, after about 30 seconds of blank screen, a pulsing white Samsung logo comes up, and I've never known which samsung logo to stop holding the power button. I believe I've tried every combination imaginable, and none of them work.
If you have an IO bootloader Do you mean Google I/O Stock bootloader? If not, I have no idea what this is in reference to.
Once you get CWM booted No idea what that is.
you can flash a stock ROM Where do I get that?
-------------
My bootloop might be different from everyone else's. Everyone else says "shut off the device, and then turn it on with the volume down/up held down. The problem with mine is that it NEVER shuts off! So, I can only do about 2 tests per day, because the only way I can shut it off is to let the battery run dead.
Mine switches from boot loop, and if I force that off, by holding down the power button for 10-15 seconds, then it immediately boots back up into "going into upload mode, cause unknown" If I force that screen off, it boots into the boot loop, so I can never boot from a "powered off" mode, again, unless I let the battery run dead.
I've tried every button pressing boot sequence I can think of with no luck. Can't I just upload something to the device in "upload mode" ? I don't need any data off this device, I just want it to be reset back to day 1, so that I can turn it on and use it.
Thanks so much for your help. As you might imagine, this is a very frustrating problem.

[Q] Atrix bootloop problem

Hi there guys, first of all thank you all so much for the support here.
I have a problem with my atrix, i googled a lot before posting, but i still can't find a solution:
I have a atrix 4G, unlocked, was running successfully neutrino 2,8 version.
After 2 months of being (almost) fully functional, the phone crashed(i didn't do anything particular at that time, i think that i was browsing google maps) suddenly and now i have continuous boot loop, i get only the classic red dual core logo, with the "unlocked" notification over it, and then after 10-15 sec it reboots.
I try to open it with holding volume down, to enter recovery, nothing happens. It reboots again. The computer doesn't see it, in this case.
I reboot it with holding volume up, says "starting RSD protocol suppport", and pc sees it and i get the cling-clong sound of usb.
I would do the recovery using rsd, but i read that it is not for unlocked devices, is this so? What can i do in this case? Thanks a lot!!!

flasing a recovery is done via fastboot so you don't have to enter recovery but fastboot (hold power and volume down till it shows fastboot, then press up) .

hello i had this problem yesterday, it happens in neutrino rom to alot of people!
and btw i could not open recovery either
ill explain what i had to do
i had to use moto-fastboot and install a new recovery, basically your recovery is dead and your rom is unbootable
heres the steps
download the moto drivers and install
http://forum.xda-developers.com/attachment.php?attachmentid=1381183&d=1349549067
then download the motofastboot zip http://forum.xda-developers.com/attachment.php?attachmentid=1381414&d=1349555102
and create a new folder in C: (computer) called Android and then drag the files from the moto zip into android
Then download a new recovery http://www.mediafire.com/?6ww8wrjrdqq9m97
place the recovery.img into the android folder
now you have all the files needed to reflash your new recovery and fix your phone the whole idea is to reinstall recovery so you can access it and wipe and install the rom fresh again
now you need to do these steps
1) Attach your phone to the PC via USB (use a port closest to the power supply)
2) Reboot phone while holding volume down until you see "fastboot"
3) Press volume up to initiate fastboot
4) On your PC click the Start menu, then in the search box type "cmd"
5) In the command prompt type the following commands (no quotes, hit enter after each command)
6a) "cd c:/android"
6b) "moto-fastboot devices"
your CMD promt should show something like this
C:\Users\Me>cd c:/android
c:\Android>fastboot devices
TA20703SX9 fastboot
c:\Android>
now if that has all worked type the following phrases
moto-fastboot erase recovery
moto-fastboot flash recovery recovery-clockwork-6.0.1.4-maguro.img
moto-fastboot reboot
now the phone should reboot, unplug the usb and pull battery out.
put battery back in and then try to boot into recovery like you normally would (power button + Vol Down)
and your new recovery should load!
from here you can wipe your whole system which i would reccomended as your current one is corrupt and install a new rom or reflash your current on onto a clean wipe. if you dont understand how to clean wipe do all of these steps, factory reset, clear cache, clean dalvik cache then go to mounts > storage and format data + format cache + format system
now install new rom and let it boot up, should bootloop a couple of times then start! if not unplug battery from phone and ask for further assitance

Thank you for your help, the problem is exactly here, i put on the usb, i power up the phone by pressing the volume down, and the phone does nothing,doesn't show the fastboot,and after 10-15 secs starts rebooting again. This is my problem!
The only response from my phone is when powering up, and pressing the volume up, it says "starting rsd protocol support"
Is there any case that my volume down is dead?

unplug usb
remove battery, then put battery back in make sure phone off (no green light)
then hold power button and vol down at the same time for a few seconds
Fastboot should appear in white writing then press up volume and it should say starting rsd protocal or something similiar
then plug in usb and follow the steps i have written above
i do exactly what you said, but doesn't show fastboot. from switched off, if i press volume up with power button, i see the message "starting rsd protocol support" .but no fastboot option!
Is there any chance that you can access adb after bootscreen? than you can use "adb reboot recovery" to get there...

When i start up phone, the only combination possible to stop restarting is by pressing power+vol up to show that with RSD. There is no other option then selectable. Power + volume down does not work, doesn't show anything, has anyone of you experienced this thing?
If the only working option you have is RSD, then I'm afraid you're stuck with having to flash a stock SBF. I hope you know/remember exactly what stock version you had installed before any modding or flashing, because the SBF has to match exactly. Choose wisely and read up as much as you can before flashing.
I have over a year now with custom roms, and i can't remember which version i had. Why do i have to find exactly the version that i had? The latest stock version won't work with rsd? It will make it hard brick?If i manage at least to recover the fastboot menus etc it would be great!
I will later also try to open it, to see if the side button "volume down" is not working,.
I have another question, in your moto atrix, if you press on startup power+vol up, are you also seeing the "starting RSD" etc option??

I have over a year now with custom roms, and i can't remember which version i had. Why do i have to find exactly the version that i had? The latest stock version won't work with rsd? It will make it hard brick?If i manage at least to recover the fastboot menus etc it would be great!

Yes, flashing a wrong SBF will most likely hardbrick your device.

Can't try right now, but as far as I know, yes, that is a standard way to enter RSD mode.
thank you, so, i know that at least my phone responds to some instructions.
Is there anyone else to suggest me to do anything else?
IN rsd mode, (other than flashing a stock random rom with chance of hardbricking,)the phone can be read by usb, can i do anything there?

Sadly no. The RSD mode can only ever be used to flash SBFs. That's it. Nothing less, nothing more.
I will now try to open it to see if vol down is not working well. If it does work, i will select a stock rom 1 year old and i will flash it using rsd, and whatever happens....:good:
I disassembled the phone, the button seems to operate fine(?).
I flashed with RSDlite the 2.3.6 version, the RSD stuck to waiting for phone to restart.
The phone restarted, the "unlocked" logo disappeared.
Starts normally, passes the red motorola logo, shows the graphic of AT&T, and after ~10sec starts restarting again. Bootloop again!
At boot, pressing power+vol up, i can still get the RSD support. Pressing power+vol down does nothing, I don't see any error messages, like the ones in hard brick.
What can i do now, any ideas please!!!
try this

Yesterday I had a hard time getting my phone into fastboot mode, after loading a bad SV kernel,it only wanted to start the RSD protocol mode. I eventually got into fastboot by plugging into the wall charger, then removing and installing the battery while holding the vol button. When fastboot appears, unplug the charger to allow sd access.
Thanks for the suggestion, i tried even this,it didn't work. The funny thing is that it shows the battery charging level full screen if i connect the charger, as it starts.
I noticed also that when i press vol down now, it takes longer to start and continue to the moving red logo, it stays for a while stable red,feels like it is thinking whether to start or not lol (if i don't press vol down, on the power up the red moto logo immediately starts the classic "waving" effects)
Anyone having any kind of suggestion?I guess you don't, right?

[Q] Neutab N7 tablet bootloader/fastboot?

I have a fairly generic Chinese tablet, a Neutab N7 (not a Nexus 7), but I have no idea how to enter the bootloader/fastboot mode.
Using adb, "adb reboot bootloader" or "adb reboot-bootloader" just makes it reboot normally.
From a shell, doing "su reboot bootloader" also reboots normally.
I tried Quick Boot from Google Play which has an option to reboot into the bootloader, but it also just ends up rebooting normally.
While powered off, I tried holding power and volume up, power and volume down, and power and both volume up and down, but they all just boot normally.
Doing "adb reboot recovery" does boot me into recovery mode, but the menu doesn't have a bootloader/fastboot option.
Does anyone have any idea how to enter the bootloader/fastboot mode for this tablet? Any help would be appreciated.

why do you want to enter the bootloader? and have they made any roms or cwm recovery for these types of generic android tablets?

Having been looking for this information myself i'm sharing real quick here what i've found. Scouring the net all over i've found NOTHING specific for these Chinese tablets but after finally getting on the scent of VROOT I downloaded and tried iROOT essentially a one-click rooter the .APK **DID NOT WORK** but the PC version **DID** can be found by googling iroot or vroot.
RE: bootloader, i've still found no way or any good info on entering the bootloader AFAIK this is locked and may not be possible without some good hard hacking on the firmware, I DO KNOW that if you try entering the "bootloader" with a reboot manager on the device u will find yourself at the "NeuTab" welcome screen and stuck. Fortunately at least in my experience, letting the tablet battery run down low you can boot back into it and root condition is still good.
Hope this helps somewhat I know its an old post but a lot of people have been looking for this info have yet to post on authors site confirming that the NeuTab also works with his software.
peace.
VE3UND
BTW I forgot to mention the site and the software (ALTHOUGH IT STATES OTHERWISE) is in Chinese. A leap of faith needed there I know but i confirm this method works. l8z
BTW^2 ALSO the android version was KitKat as received from the mfg, also have been told that Jellybean will install on the tablet after rooting and maybe is now included with device but don't quote me on that.
all in all a really nice tab for the price, especially now we have root biggest missing option: GPS but you can tether to another device with gps if you need to. Also no built in USB HOST MODE. //out
I've got the NeuTab N10 and can't get ADB to see it at all. How did you get ADB to work with your N7, were you able to find NeuTab ADB drivers somewhere?
So i recently came across this tablet in my stuff... something i picked up for the wife a few years back.
I also came across this website.... http://neutab.com/info-detail.php?InfoId=11
It has all the tools and programs that the company uses. includes all files for development of their entire line of tablets.
Thought this may be useful. just click on the link that says pheonixtools.zip and it will take you to a back end file server... This tablet is about as open sourced as it gets... so... this leads me to ask a question i have been struggling with for the last 2 years of being a member on this website...
can anyone... please... help me develop my first recovery and custom rom for this tablet? I just have never done it all the way... i have set up a couple things here and there... figured out how to strip the stock recovery and boot... but never got further than that.
Thanks for the help.
• Unzip phoenix tool.zip you just downloaded; (to open a .zip file, download WinRAR)
• In the folder of phoenix tool you just unzipped, depending on your system specs, select "drvinstaller_X64", "drvinstaller_x86" or "drvinstaller_IA64" to install tablet driver; Or you can run all three driver installer and at least one will work;
• Run "PhoenixSuit.exe", select "firmware" tab;
• Click on "Image" button, choose the firmware you just downloaded;
• Turn your tablet completely off (by press and hold power button for 20 seconds), press and hold "volume -" button, connect tablet to computer via usb cable, keep volume button held, press power button 10 times repeatedly;
• The phoenix tool should recognize the tablet. On pop-up dialog window, select if you want to format and wipe out everything on your tablet;
• The phoenix tool will start flash the firmware to the tablet. Wait till it is done;
• When upgrade is finished, disconnect your tablet from computer, press and hold power button for 10 seconds to quit upgrade mode. then press and hold power button for 2-4 seconds to turn tablet on;
Congratulations! Your tablet is now refreshed.
Ok so I have a NueTab Air 7 Android and I have talked toto their customer support which did neurologist absolutely no good. I have been trying to hard reset my tablet and do a factory reset by holding down the volume up and down keys and the power keys until it gives me the option of rebooting. However, there is no option for a factory reset. Only a Recovery mode, Fastboot mode, and Normal mode. I tired the Normal and Recovery an both sent me back to enter password that I can't rremember, which isthe why I'm resetting it lol. Finally I chose the Fastboot option and now it is stuck on that option and has been for almost an hour. It willwas not let me power off, try to hard reset, it is literally stuck. And it is a hundred percent charged. I do jot hav the optiontime to connectbe the tablet to acall Windows computer at this timetime, as the forums I have read say can possibly fix the issue. And what a surprise the customer service phone number for this specific tablet does not know how to fix it!!!!! Not surprised at all. If anyone at allthe has any ideas or knows what to do or howsomething to fix it please help meme. I'm very frustrated to say thethat least and in desperate need of help. Anything would be immensely appreciated. ~Melissa

I would love to root this tablet purely because it's my daughter's and some of the games she likes has some real funky permissions That they want! A custom rom would be nice but I will be satisfied with being able to revoke some of the permissions that the apps want to have access to.

I have yet to be able to download the zip or the firmware software. i got root with kingo pc version but that's pretty much it and I can't change the route manager because once I delete that then I don't have root anymore and can't add another one. Also I have yet to been able to get into or see download mode on this either. It just stays on the screen with the name on it and that's pretty much it. no bootloader unlock either

[Q] PleASE HELP. How to enter twrp from computer

i soft bricked my phone when installing the cyanangen 12 rom, it quit during the setup wizzard. The button combination of down and power release when seeing lg and repressing is not working. PleASE TELL ME i can enter twrp without having to restore my phone to stock. The phone will receive phone calls but that is all it does. otherwise it says setup wizzard quit and endlessly says this when you press ok. please help, despite being in los angeles, i have not found anybody capable of helping me.
Patrick--in so much need...
What is the repressing step? I've never heard of that. Isn't it just vol down and power, then release power while still holding vol down until recovery boots?
Also, do you have adb or fastboot installed on a pc? If so, adb reboot recovery from CMD if in android, or fastboot reboot recovery if in bootloader. Have you tried those?

You don't have to release the buttons, idk why so many people keep saying this. Should be the same as mine.. With the phone off just hold both power and volume down until you see it say Recovery Mode loading, then release. If that doesn't work then try the adb command while plugged in to your computer.

How do you get into bootloader if phone is bricked? It sees the phone, but it won't open up and let me look inside? Thank you
A window comes up and says that the kernal cracked.. My phone is having a hard time getting charged, could this be related?

[SOLVED] KIW-L24 soft bricked - stuck in boot loop between TWRP and Honor boot screen

Hi guys, any help would be much appreciated! I have studied all threads on XDA on bricked and boot loop'ed Honor 5X phones. I'm not a complete noob -- I have been flashing CM/LineageOS for years on Nexus 4, 5, 7, 9 and 6P, and this is the first time I have been stumped.
My KIW-L24 has an early version of LineageOS 14.1, and also TWRP 3.1.1-0 on it. I used the LineageOS updater to download a later LineageOS build, and initiated the update. As expected, the phone rebooted into TWRP, briefly showed the TWRP boot screen, but then after about 1 second, the phone reboots to the Honor boot screen for about 3 seconds, and then boots back to TWRP ... and so the cycle repeats endlessly between the two boot screens until the battery dies.
I cannot seem to get the device into bootloader/fastboot mode so that I can reflash TWRP and/or LineageOS or stock ROM. I have tried every combination of hardware keys to get the phone into fastboot (including Power+Vol Down). I tried initiating the download mode back to stock with the update.app placed in /dload/ on the sdcard (Power+Vol Down+Vol Up). I tried plugging in the PC-USB cable + Vol Down. While plugged into the PC via USB cable, I tried issuing "adb reboot bootloader" while the TWRP screen momentarily pops up (I literally have a less than a half-second when adb recognizes the phone). All without any success.
I am truly stuck! Any ideas? I have a practically brand new paperweight at the moment. :crying: Thanks very much in advance for any suggestions!
Are you sure battery isnt flat ?
You can use twrp as fas as i understand.. Correct me if i am wrong..
You can download stock rom twrp backup for your model from repository thread and try to restore backup with twrp..
Thanks, but I cannot 'use' TWRP! If I could, my problems would be easily solved, I have plenty of experience re-flashing ROMs, boot images, radios, etc.
Also, the battery is fine. At full charge, the phone powers up and immediately enters the endless boot cycle I previously described.
As soon as the phone shows the TWRP boot screen, the phone reboots again. I cannot do anything at all with TWRP. As I previously wrote, I have even tried using adb to force a reboot into fastboot while the TWRP boot screen shows for that split second (the PC momentarily recognizes the USB Android device). Unfortunately , TWRP reboots the phone too quickly.

Thanks, I just spent the another hour trying to enter Fastboot and eRecovery modes, and I must be missing something! At this point, no matter which button combination I press, I can't seem to affect the boot cycling of the phone (between TWRP and Honor boot screens).
Maybe relevant, but I am unable to even turn off the phone, it won't stop the alternating boot loop -- I don't believe in coincidences, but perhaps the power button just died? I had one Nexus 5 that started bootlooping because of the power button issue, but that was a very different behaviour than this -- the Honor deosn't get as far as booting to the OS.
GOOD LUCK !

Sound to me like you flash Non VOLTE firmware on a Volte enabled modem thats causing the boot loop, the best course of action is to restore using e-recovery, that uses a separate recovery partition so hopefully wont boot loop, remember it may take a few times to boot and you must use a usb lead that is connected to a computer, a usb charger WILL NOT DO IT !
When it boots to e-recovery select download latest firmware, you will need to connect to wifi, just follow instructions and let it restore

Erecovery should work, connect your USB to a computer and volume down + power
Another new user who posts when he has a problem and doesn't reply with an update as to what solution solved his problem, this constantly winds me up, new users who do this and dont update the thread should be kicked off
SOLVED!
Sorry for the delay of the update--I got busy and left my phone to collect dust for a while.
The ONLY solution that actually worked was to rip the phone apart and physically disconnect the battery ( !! ). Then, reconnecting the battery while holding down [Power] and [Vol -] got me into fastboot recovery, as per instructions in this thread (I had to avoid booting normally, or into recovery -- TWRP -- since either would put the phone back into the bootloop):
​https://forum.xda-developers.com/honor-5x/how-to/guide-entering-fastboot-using-key-t3400869
After that, it was smooth sailing; I was able to kill TWRP by flashing RECOVERY.img that I extracted from stock B140 image (using Huawei extractor https://forum.xda-developers.com/showthread.php?t=2433454), then force-update to stock B331, then latest TWRP and LineageOS. One hiccup: for whatever reason, I needed to do a factory reset/wipe in TWRP before it would flash LineageOS without giving error 7, despite the fact that I had just flashed the stock image.
Thank you all for your help and input!
