[Q] Huawei p7 Bootloop

A couple of days ago my Huawei p7 started to shut itself down and after that it keeps rebooting.
It starts itself up and I get into the choose your language screen and then it shuts down.
When i try to get into the system recovery (using volume & power) I get the following screen:
Android system recovery <3e>
Huawei software installed failed.
Please retry!
Shutdown system now
There is no UPDATE.APP
.............................................
FAIL
And even in system recovery it keeps rebooting.
Im kinda helpless at the moment not knowing what to do.
Did this occur to anyone ? Is there a solution for this problem ?
Thanks in advance.

You should download firmware update file from Huawei Official web site. Extract dload folder from downloaded archive and put it on your SD card. After that you should try to trigger firmware update with factory reset (method which is usually called "force update") by holding all three buttons when the phone is turned off.
But maybe your phone have some hardware problem if it restarts even in recovery mode.
UPDATE:
Does phone restarts itself when it's in fastboot mode (you can get into that mode by holding VOLUME DOWN and POWER button while phone is turned off and connected into USB port of computer just before pressing that button combination) ??

I've downloaded the update file and proceeded with your steps. I continued to trigger the firmware update with the factory reset.
At first it seemed to work, the phone started updating but after a couple of seconds it started to reboot itself again
I got the phone in fastboot mode and at this moment it does not restart itself !
I went on downloading Hisuite and at this moment it keeps searching for drivers on the network.
The searching for drivers is taking quite some time is this normal ?
Thank you very much for your help so far !

OK, maybe these are good news if you say that your phone doesn't restart when it's in fastboot mode.
I would recommend you to try to reflash your phone's stock recovery and boot images with those extracted from firmware that you are trying to install.
Follow these steps:
Download Huawei Extractor tool from here,
Open update.app with Huawei Extractor and extract next two images: RECOVERY and BOOT (you can do that by selecting those two images while holding CTRL button, then right click > Extract Selected),
When extracted, rename those two images into "recovery.img" and "boot.img",
Copy those two images into "platform-tools" folder of Android SDK,
Run command prompt and go to "platform-tools" folder by using "cd" command,
Start your phone into fastboot mode,
Enter following command into command prompt: "fastboot devices" (without quotes), you should get your phone's serial number listed, if that's right, go to the next step,
Enter: "fastboot oem get-bootinfo", it needs to say that your bootloader is unlocked. If it's not you need to enter the next command "fastboot oem unlock 1234567812345678", where "1234567812345678" should be replaced with unlock code that is unique for your device. Instructions which explain how to obtain unlock code for your device can be found here,
Flash your phone's recovery with "fastboot flash recovery recovery.img",
Flash your phone's boot image with: "fastboot flash boot boot.img",
After successful flashing of both images, turn your phone off by holding POWER button for a several seconds,
Prepare SD card on your PC by formatting SD card and copying "dload" folder of phone's firmware onto SD card,
After you insert SD card into phone, start your phone with "forced install" method by holding all three buttons on your phone.
After that your phone should process firmware install successfully if there is no some hardware issues. Good luck and inform us about your progress.

Enter: "fastboot oem get-bootinfo", it needs to say that your bootloader is unlocked, if it's not read this,
Flash your phone's recovery with "fastboot flash recovery recovery.img",
Flash your phone's boot image with: "fastboot flash boot boot.img",

Hi,
I've got the same issue.
When I start to "force install" method, my phone doesn't boot.
It just stay in a state of "charging" but nothing append.
I flashed boot and recovery with Fastboot.
But now, when I start the phone in Fastboot&Rescue Mode, the device doesn't appear in the liste when I run adb devices.
But when I start in the "force install" mode, adb devices returns the serial of the phone (but it doesn't respond to fastboot command).
Are there other files to flash on the phone than juste recovery and boot ?
Thank's for those steps, i'll continue to try to flash again.
Edit :
Ok phone is back !
The problem came from my SD Card, I had not only the dload folder, but an other file.
Format SD Card -> dload folder -> "force install" method -> ENJOY !
Thank's a lot !

I followed all your steps but i get stuck at step 7. When I give the command fastboot devices it doesn't show my phone's serial number. Instead it shows a ? (question mark).
Did I do something wrong or is there a solution for this?
Thanks in advance!

Maybe you should try other version of platform tools. I would recommend you to download adt-bundle-windows-x86_64-20140702.zip (x64) or adt-bundle-windows-x86-20140702.zip (x32) from "Android SDK" official web pages (I assume that your are using Windows OS). After download extract only "platform-tools" directory to the root of Windows C:\ partition and try described procedure again.
However if you are still getting question marks instead of phone's serial number, you should ignore that step and go onto the next one. I had the same problem in the past and flash commands were successful even serial number wasn't been displayed.
Keep us informed about your progress. Good luck zbnd !!

Thanks for your response !
So I followed through like you said. Gave the fastboot oem get-bootinfo command and then I got (bootloader) locked. So I followed the bootloader's unlock code (official way), entered my product SN and product IMEI, used the Huawei Product ID generator followed the procedure and all I get is : Please input the correct Product ID
What did I do wrong this time ? I'm not sure if it's even possible to do this wrong. Is there another way around ?

You can unlock with Vroot, like I did. I didn't try to get a serial from Huawei.
For the Fastboot command 'Fastboot device's I had a ? too, but with 'adb devices' command, I got my serial number.

I've downloaded Vroot (english version) but when i connect my phone it says not support mode
I tried to connect while in fastboot&rescue mode, because this is the only way the phone stays on without restarting.
I then tried to connect without fastboot&rescue mode. But my phone keeps rebooting. I did get a message that USB debugging is disabled. However I can't enable usb debugging because my phone won't boot up normally.

@Pboguet
You should read carefully because your answer has no sense for the phone which is in state like zbnd's phone is.
 @zbnd
Maybe you are doing something wrong. You can send me your's phone serial number and IMEI in PM inbox, I will try to generate unlock code for you.

Despite following all your steps my phone keeps rebooting

Sorry to hear that. Did you manage to make all steps that I described to you? Can you share more informations about your current efforts please.

After unlocking my phone I got the message unlocked in CMD.
I then flashed recovery and boot. Both times it said that the flash was succesfull, this only took a few seconds I don't know if thats normal? I then followed your last steps ( dload folder etc) and put the SD card in my phone.
It start installing but after approximetaly 25 seconds the phone shuts itself down and then reboots.
The procedure then starts again and it starts installing followed by shutting down and rebooting.

I'm sorry to hear that. Seems like it's some hardware issue.
However I still have one more idea that you can try in fastboot mode. I would recommend you to install entire firmware manually with fastboot commands.
By following previously described procedure try to extract with "Huawei Extractor" tool next images also: SYSTEM, USERDATA, CUST and CACHE.
After step number 10, try to use next commands also:
"fastboot flash system system.img"
"fastboot flash cust cust.img"
"fastboot flash userdata userdata.img"
"fastboot flash cache cache.img"
When you are finished with flashing of all images, use "fastboot reboot" command to restart your phone. Steps 11, 12 and 13 should be ignored this time.
Let me know the result

Hey, I'm glad I found this forum, because I have exactly the same problem! Since zbnd did not reply I wanted to let you know that flashing boot.img, recovery.img, cache.img, userdata.img, cust.img and system.img via fastboot did not work
The commandline for each file said "OKAY" and "finished" therefore I assume the process(es) completed succesfully.
Maybe I should tell you some information and the steps I did with my P7:
- my device is a branded german telekom version with firmware P7-L10-V100R001C150B122​- because of crappy pink telekom bootlogo und bloatware I wanted to flash the original huawei firmware so I downloaded the B126 from the official website and updated via force update method​- at the end of the update process i got the messages "huawei cust fail" and "update_post_process fail" but when I rebootet the B126 was installed and showed a message "Defect report reminders - This is an internal test version. Please report defects to Yangyexiao 00143718" - can't be correct, I thought​- after googling a lot and reading through several forums I rooted my device with RootGenius, installed HiSuite and Android-SDK (driver were installed correctly, adb devices showed a device with serial) and deleted the "cust" directory on my phone - at that point everything still worked​- next step: I installed TWRP 2.7.1.0, made an updateable zip file with huawei update extractor (including system.img, userdata.img, cust.img and boot.img) and flashed it via TWRP. The process completed succesfully, but needed only a few seconds. After that I got this bootloop at the language selection​- then I wanted to return to the last functioning state, so I flashed the stock recovery via fastboot and started with force update method. But after a few seconds the device rebooted during the update process which led to another (maybe the same) bootloop. I had to remove the sd card, but the device continued to reboot in recovery mode. So i installed TWRP 2.7.1.0 again​- Then I tried to restore a B133 backup I got from another forum, but it obviously did not work (see attached image)​
Now I just don't know what to do ... I get a bootloop in stock recovery and I get a bootloop in TWRP 2.8.0.0.
Only TWRP 2.7.1.0 does not reboot. What is about the other files inside the UPDATE.APP (modemimage.img, efi.img, etc)? Is it possible that some of these files are needed?
Thanks in advance...

If this recovery works than try:
1. Save this Se7en or this HRT or this custom MIUI ROM on SD card
2 .Wipe in TWRP everything (dalvik, system,data,cust, internal) except external (SD card). Internal only if You have a backup or not important data there.
4. Install zipp ROM from external memory. Sometimes try more than one time in fail case. For HRT ROM especially.
Let me know if helped.

I tried se7en and miui.
I wiped dalvik,system,data,internal,cache and custom, which only lasted about 2 seconds, but said succesful (Is that enough to delete all partitions?).
Installation of both custom roms completed succesfully and lastet several seconds (max 1 min I think).
Se7en: reboot -> huawei logo -> reboot -> language selection (in the style of stock rom?) -> reboot ...
Miui: reboot -> miui logo -> reboot -> language selection (miui style) -> reboot -> wifi selection (I skipped) -> searching for sim card -> reboot

To use fastboot you need to unlock bootloader first. And before flash, you need to erase partition first, for a proper job. Please read well about the fastboot procedure is a dangerous procedure

My bootloader is unlocked, but fastboot sais I don't have permission to erase partitions ...

[HELP] Android not booting [URGENT]

It's a bit urgent to get solved, I'm at college, and that's the only way to talk with my parents, being 1 or 2 days without answering them would be a problem, since they will start to get worried.
Phone: Motorola Moto G 2014, XT1063
Using Team Win Recovery Project v2.8.0.1
Basically I was trying to update to the Android 5.0, since I had my phone rooted, I decided to go with an customized ROM.
DIdn't understand why, but it f**ed up.
Basically I cleaned everything, and in an act of desperation I also lost my sdcard, I've been trying to install the ROM through sideload, but it's not working, I get the error *failed to write data protocol fault no status*, and the phone keeps rebooting, and stuck in the "WARNING BOOTLOADER UNLOCKED"
I appreciate any kind of help, as I said, it's really important to solve this ASAP.
Thanks in advance!

Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck

1) download TWRP 2.8.4.0 and install it through fastboot.
2) Since you have no sdcard we will use the mtp capability of twrp
-- Boot into your newly installed recovery. Check the version
-- Go to Mount and disable mtp and unmount everything. Now enable mtp. You should see that Data is mounting automatically and should appear on your Computer.
-- Transfer your ROM (I recommend The Titan Prime Rom for XT1063/64. It's based on stock and much more polished than CM12)
-- Download and transfer pa-gapps (MICRO MODULAR PACKAGE).
-- Download and transfer latest SuperSU (min version 2.45 is required by our device).
-- Wipe Dalvik, Cache, System and Data
-- Now Flash ROM, GApps and SuperSU. reboot and wait. it will take a couple of minutes.

Doppel u r right. follow doppel steps.

The device appear as offline in the fastboot, sometimes even doesn't appear, where can I get the drivers?
I searched for naked versions, and "universal" ones, but none seems to work.

You can get Motorola drivers here. You probably also need a recent version of adb and fastboot. You can ge it here Minimal ADB and Fastboot. Install it.
start "Minimal ADB and Fastboot" by navigating to the Start Menu Folder you choose to create during installation or the desktop shortcut you choose to create and select "Minimal ADB and Fastboot"
You should now see a command window open.
Put your device in fastboot mode and connect usb.
Now just do verify type this command
Code:
fastboot devices
the output should show something like this (your number is different)
Code:
fastboot devices
ZX1D225X69 fastboot
now put your recovery.img into the directory where your command window is open and start flashing
Code:
fastboot flash recovery NAME_OF_RECOVERY.img

You need a wall charger. USB from pc does not supply enough power. And you need at least 25% (ish) otherwise fastboot will refuse do do anything.

On the MOUNT and UNMOUNT processing I don't see anything on my PC, I don't even know how to unmount it. It only appears Enable MTP and disable.
How am I supposed to load the ROMS?
Tried with sideload but got an errror : "Error executing updater binary in zip .."
Seems like the drivers aren't working properly, I have Windows 8.1, on the site it doesn't talk about it, this might be the problem? Cause I instaled motorola device manager, I scan for drivers but it doens't find anything, and the phone apperas with the yellow triangle on the Device Manager.

EDIT: I managed to boot the Titan 5.0.2, but now it's stuck in the 4 balls moving around, i waited for about 1hour.

Can't get out of Fastboot.

"Cyanogendmod.Org / Install CM for z3c / Unlock Your Xperia Z3 Compact" <--- That's the URL somehow.
Followed this instruction. Got myself the 12.1 .zip and .img.
I get error installaing the .zip and the .img isn't even an option:
The old rom is infinitly loading in that blue/purple wave line.
I then turn the phone off by holding down the power button until the phone restarts.
My history:
>Pressing up and down on the button rockers.
>Cyanogen Recovery starts.
>I choose "Wipe data/factory reset".
>I choose "Apply update".
(Apply from ADB doesn't work as it seems as ADB has no access for USB debugging. That's why install it from an external SD)
>Install "cm-12.1-20160918-NIGHTLY-z3c.zip" or its copy that I named "update.zip".
Error message:
[CAN'T POST PICTURE BECAUSE XDA HAS VERY FUNNY MEME RULES XDDD]
Private message maybe...? Can I send you guys URL pics via PM?
How can I get out of this loop?

If you want to go back to stock, use flashtool and flash whatever version you want (FTF method), I had an issue with flashing CM too, it said this is for aries but this device is z3c etc. Is this your problem?

I hope you can decypher the URL h t t p : / / t i n y u r l . c o m / j 6 4 u 8 u a

Few things you can do:
1- Download the ROM again, might be corrupted download.
2- Flash Lollipop FTF(not necessary), Flash TWRP recovery, boot into recovery, (If it asks, swipe to allow modifications to system), wipe everything (system,cache,dalvik,data), flash the ROM through TWRP recovery.
3- If it gives the error that I talked about in my first message, let me know.

I tried #1 but I'm already stuck with the "SONY XPERIA" blackscreen at the very beginning when booting the smartphone. I suppose it's because of the failed installation and the not choosing of "Wipe clean/factory reset".
I hope that still doesn't count as bricking. I let the accumulator run dry and reload the battery and try to get into the Cyanogenmod Recovery again. Right now nothing is possible. =/
I hope that doesn't count as bricking. If so: These special OTG USB thingies fix a lot I heard, should I get myself one?

If you are on CM recovery, then there is the problem. AFAIK you can't flash anything through that, so you have to push TWRP on your device using fastboot and then flash AOSP/CM rom you want.

That's called a soft-brick. You should install the ADB drivers for your phone on your PC and then download TWRP for your phone (.img file) and rename the TWRP you downloaded to recovery.img .
You should put the recovery.img into the folder where your ADB drivers are installed, then Shift + RClick on that folder then select Open Command Window Here. Connect your phone in fastboot mode to your PC (Keep Vol. Up button then plug in your device). Type the following commands:
fastboot flash boot recovery.img
fastboot reboot
If you've done it all correctly, your phone should boot into TWRP recovery. From there you should go to wipe-advanced wipe and wipe your Cache,Dalvik Cache, System, Boot. DO NOT REBOOT NOW. You should go back to main menu and choose install, then choose the ROM you want to install. It should flash it if you don't have a corrupted file. After flashing, you can safely reboot your phone, don't forget to flash GApps if you want Google features on your Cyanogen, hope I helped!

K, 90% of this works. I got the TWRP "app" and I cleaned the cache and all that, but I had to reboot. You see:
To transfer new media I need to remove my external SD from the z3c to my old LG. The LG is connected with my PC and is therefore a kind of card-reader. I tried 2 different nightly thingies.
I still get extraction errors, see:
h t t p : / / t i n y u r l . c o m / h j j d 4 o b
I downloaded 2 different nightlies 6 times already. I dunno. Somethings off here.
Also: For what is the recovery.img? Should I install it afterwards?
I have to restart the phone in order to replug the SD card and get recognigzed by the TWRP.
I did everything from this:

OK, your problem is that you messed up your system, so wiping it is not gonna solve this issue. You need to download a stock firmware file (an FTF file) and flash it through Flashtool, because your device name seems to be "." which is why you were getting "error 7". As for the recovery.img, you will use it to flash TWRP recovery on your phone. TWRP app doesn't work correctly if you don't flash it to your recovery partition so do as follows:
1- Download Flashtool, install the drivers of your device for Flashtool (you can search it on xda forums), download an FTF file, any of them should do, but as you will install CM 12.1, I recommend a Lollipop FTF.
2- Flash the firmware through Flashtool. This will turn your phone into a stock one. Unlock your bootloader if you haven't already, which I believe you have.
3- Flash the TWRP recovery through fastboot (follow my earlier instructions)
4- After you open TWRP recovery do the wipes, note that you can still connect your phone to your computer for file transfers in TWRP Recovery.
5- Install the CM zip file through recovery
IF YOU GET ERROR 7 SAYING :this package is for device: D5803, D5833, z3c; this device is aries.
7- Open the CM 12.1 zip file on your computer and proceed to META-INF/com/google/android directory.
8- In that folder you should see "updater-script", extract it to somewhere and open it with Notepad.
9- Once you open it press Ctrl + H to change some of the lines.
10- Write "D5833" without the quotation marks in the first space and write "aries" without the quotation marks into the second space and click replace all.
(This will change all "D5833" to "aries" in the file therefore making it usable for your device) Save the file and put it into the directory of where you found it, replace it with the original.
11- Now put the edited .zip file into your phone storage, and flash it through recovery. It should work. :good:

It won't matter. Because when he flashes the CM, it'll flash the CM Recovery along with it.

Yea I know, but before that, he needs to have a working TWRP on right partition to be able to even flash any rom.

That's why I wrote those steps for him/her to follow. If you flash TWRP to boot partition, when you boot the phone, it will go straight into TWRP. If you flash it to recovery partition, you'll have to boot it manually.

FlashTool says the firmware has been flashed so I don't understand what are you trying to do after that? After flashing the FTF file you should flash TWRP through "FASTBOOT". Then follow the instructions.

K, did everything you said. Read everything five-times. Replaced "D5833" to "aries" and all that stuff. Still getting ERROR 7.
The phone is still in TWRP Recovery from FASTBOOT / BOOTLOAD because I "constantly" charge it to stay in recovery. If I had found this Mount option earlier... kinda feel stupid for that. So I still get ERROR 7. I copied the modified .zip to internal storage and SD card to see if I get the same error twice. And yeah.
Exact error message in red letters:
"Updater process ended with ERROR: 7
Error installing zip file ' /external-sd/cm-12.1-20160918-NIGHTLY-z3c.zip'
Updating partition details...
... done"
So I forethought and cleaned the cache and need somewhat new instructions.
Also:
I suppose with "Advanced Wipe" and your instructions you meant this points, right?:

OK, so try flashing TWRP to recovery partition to get you out of TWRP after you boot by writing these commands in the ADB:,
fastboot flash recovery recovery.img
fastboot reboot recovery
This will flash the TWRP to recovery partition and will boot you into TWRP. As you do this you won't have a go at the recovery again but for this time. You can reach the TWRP by pressing the Vol. Down button when the phone vibrates at the boot. Also if you want to force shutdown your phone you can use Vol. Up + Power Button combination for a few secs.

Thank you so much for posting where you found this, this is exactly what I needed!!! You saved my tablet, it is much appreciated! :good:

Flashing Factory Image
The following instructions worked for me when trying to reflash the factory firmware for the ATT Asus MemoPad 7 LTE (ME375CL). I did originally try using the Asus Flash Tool and the raw firmware file (link below) but the tool said it could not unzip the package for some reason or another. So the steps below show how I did it using ADB with fastboot.
I ASSUME NO LIABILITY SHOULD THIS GO WRONG FOR YOU! However, it probably shouldn't matter if you are bricked, I doubt it will make it any worse Either way, I will not replace your tablet or be responsible for troubleshooting it should you mess it up more...
This scenario is based on the tablet stuck on the Asus boot screen and not going any further. I was trying some in depth rooting attempts and bricked it badly. I was then trying to install a custom recovery and that is why I could not reset it and bricked it.
PRE-REQS:
1. ADB installed - Download: https://drive.google.com/open?id=0B0fKccJIuWsna04wMjY1eG9YREU
2. Asus Drivers installed
3. Firmware - Download: https://drive.google.com/open?id=0B0fKccJIuWsnWGhwYzA0Vkluc2s (file is 1 Gb + in size, may take a bit)
SETUP:
If you already have a working ADB setup, do not download the one above. If you are using the one above, I extracted the folder into my C: drive, so the path for ADB would be C:\adb (to keep it simple and less typing).
MAKE SURE THE ASUS DRIVERS ARE INSTALLED! If you have plugged the tablet in to a pc before, they should already be there. Otherwise search, download and install the appropriate drivers.
INSTRUCTIONS:
Extract the firmware zip file to somewhere easily accessible like your desktop. In there, you should see the boot.img, recovery.img and system.img files, copy/paste those files to your ADB folder (for easier typing later on). There are also additional files like these but start with "unsigned_", do NOT use those!
1. Ensure you probably have at least 30% battery charge, I would still recommend more though.
2. Put the tablet in Fastboot mode by ensuring the tablet is completely powered down and then press/hold the VOLUME UP and POWER keys at the same time. When the Asus screen appears, let go of the POWER button but continue to hold the VOLUME UP button. Let go of the VOLUME UP button when the fastboot screen appears.
3. Plug the tablet in to the computer and then open a CMD prompt as administrator.
4. The following uses the ADB downloaded and placed in the folder as listed above, you may need to adjust the location path as needed if you already have ADB installed or located in a different path.
Type in the following without the quotes: "cd c:\adb" (this will change the path to the ADB files for the CMD prompt)
Type in the following without the quotes: "fastboot devices" (you should then see a device listed)
Type in the following without the quotes: "fastboot flash recovery recovery.img" (flashes the factory recovery image)
Type in the following without the quotes: "fastboot flash system system.img" (flashes the factory system image, may take a while to flash)
Type in the following without the quotes: "fastboot flash boot boot.img" (flashes the factory boot image)
5. Once those 3 images have been flashed, you should have seen a message that says "OKAY" after each one. You should be fine as long as you do not have any red error messages on your tablet.
Type in the following without the quotes: "fastboot reboot" (reboots device normally)
6. If all goes well, it should now boot to the Asus screen and then go to the ATT screen. If so, it will stay on the ATT screen for a while, just wait it out. Mine took about 12-15 minutes and then it opened to the new setup screen to set the tablet up as if its new!
This is how I was able to recover my bricked tablet, hopefully it can help someone else that may run into this.

John, thank you for the write-up. Just bought my ME375CL with 4.4.4.4.
When I try to flash the recovery partition, I get the following error:
C:\Users\Myself\Desktop\adb>fastboot flash recovery recovery.img
target reported max download size of 536870912 bytes
sending 'recovery' (11312 KB)...

Click to collapse
and on the tablet's screen:
FASTBOOT CMD WAITING...

E:recovery flash failed!
FLASH FAILED!
RESULT: FAIL(flash_cmds error! )
Click to expand...
Click to collapse
I haven't tried the other commands for system.img or boot.img as I don't want to do anything out of order from the write-up. Ever run into this?

The firmware in the download is 5.1.1, not 4.4.4. That is probably the issue. If you are running good on that, I would try rooting it instead. If you are just wanting to upgrade, you will need to have an active AT&T SIM in the tablet to upgrade over the air. I am not sure if there is a flashable upgrade or not somewhere.

Oh ok John. I misread the title of the thread. I thought it was for updating from 4 to 5.
Quick question then: Is it possible, using the adb / fastboot tools, to backup the current 4.4.4.4 before I allow the tablet to update to Lollipop? After reading around, I understand that Lollipop can't be rooted but I have no real concern for it. But just in case I need the tablet to do something else in the future, I'd like to be able to return it to kit kat to be able to root.

Once you upgrade to lollipop, there is no downgrading for this tablet. There really is not much development for this device. I have kind of been working on a lollipop root when I can. Between my limited time and knowledge of android, I can't promise anything.

Overcoming red messages?
Dear John,
Thank you very much for your help. My device runs KitKat 4.4, I can't upgrade over the air, as I damaged my sim slot struggling to remove a stuck nano sim, which I had inserted before I realized that it required a micro sim. (I'd wrongly assumed that by now the world uses only nano).
I followed the steps above, which you wrote so clearly for lay men, thank you a lot.
The flash for recovery.img and system.img worked fine (no red error messages on device).
The flash for boot.img had a red error message.
Might you have an idea or workaround on how I can address this?
If it refuses, is it possible to factory reset?
Thank you very much again for any words of advice and kind regards.

Sounds odd that it did 2 out of 3 flashes. After you flashed those and rebooted, are you still on KitKat or did it actually update to Lollipop (5.1)? I ask because I assume the system image that flashed would be the operating system.
I still want to stress that this post is for recovering a bricked tablet that will not boot at all. I would not suggest using this as a flashing upgrade as I do not know if it will truly work. If you are still on KK (even after flashing) you could try installing the Asus Flash Tool and use the raw firmware that you downloaded and try it that way. It did not work for me so that is why I used fastboot. It might work for you.

As a follow up on your question above, Tab restart stalled at a screen (after the Asus logo), presenting some options to do recovery, reboot, factory reset, etc. (factory reset did not help), and red error messages at bottom.
To the GOOD news for anyone interested. I used the Asus Flash Tool and the firmware zip for 5.1.1 (many thanks for the advice).
Note: Tool did not install correctly on Win10 pc, citing error in installing some devcon.exe or similar file (guess that may be a firewall/antivirus issue).
Flash tool took some 15 or so mins unzipping firmware, after which I saw some action on the tab. Another 15 mins, and it rebooted to the At&t logo, stayed here for another 15 mins and unraveled a whole new device on Android 5.1

Glad to hear it worked for you and that I guess you can use this to flash upgrade from kitkat!

There is working way to root our device on lollipop! It is for the other Asus model, but it works for our
http://4pda.ru/forum/index.php?s=&showtopic=640814&view=findpost&p=53047686

I will check this out!

The root works, installed without any issues and verified with a root checker!
Here is a direct download from my Drive folder: https://drive.google.com/open?id=0B0fKccJIuWsnN21ZbnZpc2F6b1E
1. Download the file above.
2. Extract the zip contents.
3. Plug your ME375CL tablet in to pc via usb cable.
4. Make sure you have enabled Developer Mode and allowed USB Debugging first!
5. Open the folder you extracted and double click the "Root-One-Click.cmd" file.
6. It should reboot to fastboot mode and flash the needed files and then reboot again.
You should now have root access. Verify this by installing a root checker app from the play store. Keep in mind, it may say root not installed on the first run. Sometimes it will take a moment for superuser to initially run or prompt for access.
Side note: the root uninstall did not seem to work, got an error...but oh well, the point is to have root!
Thanks go to @little_pindos for finding this file...you are a rockstar!

Anyone get xposed on LP?

ATT Boot Up Sound
Tired of the ATT boot sound? If you used the rooting method above, then you can get rid of the annoying ATT startup sound by doing the following:
1. Install a Root Browser app (I recommend Rom Toolbox Pro, it has a built in file manager)
2. Navigate to the following path:
root/system/media
3. Find the file named "powerup.wav"
4. Simply rename the file by adding .bak to the end (ex - powerup.wav.bak)
5. Make sure it took the name change (some file managers have issues with that)
6. Reboot and see if it got rid of the sound!
You can also use your own startup sounds as long as they are in a .wav format, I believe. Make sure that the name of the file is powerup.wav.

You can also change your boot animation with "boot animation" app.
Best tweak IMO is adding "ro.config.low_ram=true" to build prop, or installing the low ram device xposed module if we can get it to work (both do the same thing). You gain about 100mb more free RAM on average.

Why am I getting a corrupt image? Does anyone recommend a better Stock Recovery-Image source, perhaps where I can confirm the hashtag of the download and image extraction? TWRP does not seem to be an option for MotoE6/ No-RAMdisk devices.

I don't recommend images from Get Droid Tips, Moto E6 Stock Collection while they have the build numbers for the downloads, they did not show that there are various model numbers for the Moto E6. My guess is this is the likely cause of the "corrupt" image message from my flash recovery attempt.

Why am I getting a corrupt image? Does anyone recommend a better Stock Recovery-Image source, perhaps where I can confirm the hashtag of the download and image extraction? TWRP does not seem to be an option for MotoE6/ No-RAMdisk devices.

I don't know why this occurs, but it's "normal". What the installer guide doesn't tell you is:
- when you flash the patched recovery, you can't then use fastboot to get to recovery mode (well, you can...but it doesn't work). Instead, you MUST use the fastboot navigation keys (vol up/down and power) to go to recovery. When you do that, you'll boot the whole system into a rooted state (you won't see a recovery menu of any kind).
- at least on my phone, when you do this you are rooted for exactly one session. Next time you boot, the recovery image you flashed will be replaced with the "factory" original one. There is a work-around for this, but that's the behavior.
- if you are trying to install EdXposed, I don't believe you can do so just with the recovery-image method. You have to install the whole of Magisk (many MB) and I haven't figured out how to do this yet. (many, many false starts...)

Ok, Thanks. Looks like my attempt to flash ( from Get Droid Tips, Moto E6 Stock Collection, ) was not the correct Moto E6 model. Phone boots still to the factory, and not rooted, but has a "bad key" error.. Boot to Recovery just responds "no command"
I did find now download the correct image from https://mirrors.lolinet.com/firmware/moto/surfna/official/ (matched by the Correct Moto E6 XT2005 model and build) but now ADB does not want to push or pull files. Unsure how to proceed.

I got my "stock ROM" by using Moto's "Rescue and Smart Assistant" tool -- it interrogates the phone, and lets you download the correct ZIP file automatically. Obviously, you do'nt want to actually install the ZIP -- you just want it downloaded. It puts the ZIP into a location it discloses, so you can find it. ;-)
Was ADB pushing/pulling files before? That's really weird if it did...but in any case, when the phone is booted to the normal system you can just copy the files over to the phone via the standard USB file sharing connection. If that's not working, you may need to reainstall the USB drivers on your PC. Don't forget to enable USB file sharing on the phone!

ADB was pushing and pulling. I found the XDA posting that might help solve this official-tool-windows-adb-fastboot-and-drivers-15-seconds-ADB-installer-v1-4-3.2588979/. I'll update my drivers per the video found here, and try again.
While deleting some old Samsung Drivers was probably necessary, the error remained. Searched and found that the directory "/SD Card" is incorrect, even though topjohnwu.github failed to explain that "SD Card" is not the same folder as seen in the windows USB Link. It is the Internal SD Card which the ADB uses, which I find on windows at "Internal Shared Storage/Download". Once I moved the file on my phone to that folder , I was able to Pull the file using the command "ADB Pull \Sdcard\download.."

Reflashed my patched majesk recovery image. But, I can not boot recovery. Fastboot gives me a "no command" message. Screen always displays "bad key" on any boot. Holding power and tapping upkey does nothing in attempt to Boot to Recovery.

I believe that the "bad key" message will occur whenever you have an unlocked bootloader. There is a way to hide it (search within XDA forums, you'll find several posts), but I leave it as is so I get a positive indicator of where I really am.
You say "Fastboot gives me a 'no command' message": I think what you mean is "when I go from Fastboot to Recovery mode, a get a 'no command' message." -- because the only time I've ever seen that message is under the Android-robot icon, which indicates "you're in stock recovery mode." When you are there, you should be able to get to the command menu by clicking power-on and volume-up simultaneously. If you don't, do a power cycle and try again.
You'll know you've booted the root mode when you don't see the "bad key" message, but instead see something like "Unsigned or corrupt image" when you go into recovery mode (and you won't see the normal Android icon or "no command" message).
In my experience with this phone, if you are in bootloader and use your PC to get you to recovery mode (fastboot reboot recovery from the command line), it may not work. The only way to reliably get into real recovery mode is to do a power cycle on the phone, go into fastboot, and then use the phone's buttons to get to recovery.
Also note that if all that you have done is the Magisk modify-recovery-image strategy, you get one (and only one) attempt to run as rooted. Any time you go thru a power-on reset of the phone, your modded-recovery image will be erased and replaced with the factory one.
In my various runs, I've determined that once you've achieved root access you can soft-reboot the phone and remain in root. Anything you install there will survive soft-reboots. But if you do a hard reboot, next time you go into root you may have to reinstall EdXposed and supporting libraries, and reactivate stuff for everything to work.
Sadly, the Xposed module I was doing all this for doesn't seem to work under EdXposed, even though it's supposed to. So it was a days-long wild goose chase.

Thanks for you help. I finally got a correct flash and boot to a rooted recovery. Looks like Top Johns' Magisk Instruction Page needs some corrections: Like explaining that "SDCard" shows as [internal storage] on the PC and that the external Storage is the [SD Card] directory. He fails to tell to rename the magisk_patched file to "recovery. img" before flashing it. (An obvious error but easy to overlook when you are following an unfamiliar command syntax) . The "bad key" message and "corrupt signature" message explanation is useful info too. He fails to let you know how to even check for a successful root

And to add to the fun...Magisk Manager has/had a bug where it will tell you that your phone *doesn't* have a RAMdisk but it actually does....sometimes. So you might try to do the boot.img patch instead of the recovery.img one--that would give you a permanent root, rather than a transitory one. I didn't bother to check that out, as the whole reason I was rooting was to use an Xposed module that doesn't seem to work.
Let me know if you try that strategy out and it works...

The instructions assume that you are somewhat familiar with Android, adb and fastboot. There's plenty of info and guides on that around the web, so it would be redundant for John to add that too (and the instructions would become way too long).
There are also many devices specific things that he's never gonna be able to cover. The fractured nature of Android is just too much for that...
If you have suggestions though, you can always open a PR on GitHub with your proposed changes and clarifications.

That's not a bug with Magisk, but yet another issue with Android's fractured ecosystem. John actually covers that in his documentation. Check this page, and in particular the last paragraph:
