and finally after retry 10 it is showing
E: Can't find /sdcard/update.zip

This should be in general (I wish I was a moderator, I'd do it myself)

I see the same errors when I go into recovery, but I can still launch the fake flash version of recovery. Make sure the update.zip is the correct version.
Recovery is failing to mount your SD card. I'm not sure what the issue is
Did you try USB Unbrick?
year!
http://www.megaupload.com/?d=RTEY0Q97
get that adb.zip
then you should get some recovery files. Hmmm, how to upload??
pull recovery files to the "files" folder.
just run:
adb push files /
adb shell busybox --install /sbin
adb shell nohup /sbin/recovery &
you could get into recovery and flash rom again.
try searching on youtube
Put the Clockwork Mod update.zip and your backup or another ROM (as zip file) on your SD Card. Then press Volume down + Power Button. Afterwards select Recovery and wait until you see the red triangle. When you see the red triangle press Volume up + Power and wait until the Recovery screen appears. There you select Apply update.zip and your phone should boot into Clockwork Mod Recovery. From there you can flash a new ROM or restore your NANDROID Backup.
heres another way... go download this http://www.megaupload.com/?d=XBAOCSWZ
and find testimage.zip in it. Put it on your phone's sdcard renaming it to LEGEIMG.zip
off the phone and go to boot loader and start back from unrooted eclair...
the link above is form got it form this post http://forum.xda-developers.com/showthread.php?t=894465
but anyway... since you like e2 recovery so much... you did not do a factory reset... go do that and the loop should go away....
@spiritusrector
THANKS SOO MUCH lol...you just saved me 35 bucks
answer
go on youtube and search for androidreviews123....he has a guide on how to unbrick

Boot Loop Nexus 4 - dead eMMC?

Recently, my Nexus 4 has been crashing randomly - shutting off with no warning or notice. It has always rebooted back up without issues. Last night, however, it just got stuck in a boot loop - spinning balls for hours on end.
Bootloader and Recovery Mode come up with no trouble.
The phone is and always has been pure OEM/stock. I've only ever updated using built in OTA process.
I tried to reflash to stock using Wug's Nexus Toolkit, but it repeatedly failed saying the device was locked. I tried to unlock the bootloader, but that seems to require a reboot to take hold, and every time I tried the reboot it would loop again.
In Recovery Mode, I get the following:
E:failed to mount /cache (Invalid argument)
E: Can't mount /cache/recovery/log
E:failed to mount /cache (Invalid argiument)
E:Can't mount /cache/recovery/last_log
E:can t open /cache/recovery/last_log
E:can t mount /cache/recovery/last_install
E:can t open /cache/recovery/last_install​
I have downloaded the full image and tried flashing the cache, and system with no effect. Toolkit doesn't show an error, but nothing changes.
Does anyone have any suggestions? I'm at a loss.
Did you try
fastboot erase cache.img
fastboot flash cache cache.img
Then perform wipe data/factory reset before booting into android.

Reboot problem - Failed to mount cache (Boot loop)

Hi guys,
I'm seeking your help in assisting me getting my tablet works again. It's Nexus 7 2012 with last updated Android version 5.1.1 (LMY47V). The problem started when the tablet suddenly restarted and the loading intro (that appears after Google's logo) didn't change for long time. I entered the recovery mode and tried to wipe cache partition unfortunately which made my problem worse! upon reboot I only get the Google logo repeatedly with no change!
The recovery logs are as follow:
E: failed to mount /cache (invalid argument)
E: Can't mount / cache/recovery/log
E: Can't open / cache/recovery/log
I've searched on the forum and found an opinion that I should download the Android Image from the developers.google website and unzip till I find a cache.img file, but it wasn't there after I've extracted the image zip file.
I've important data that I need to retrieve from the tablet. What should I do? Taking into consideration that I didn't unroot the tablet but I did make the undebugging step before (working with pdaNet).
Thank you very much in advance!

How to root a S8 G950F Exynos with failed integrity verification without wipe ?

Dear all,
I tried since yesterday to root my S8 Exynos (G950F). My phone is crypted and when I try to root with magisk via TWRP, I have errors to access to datas. When the system boot, I have the error unable to restart your phone. the integrity verification has failed....
Then via TWRP and the shell, I made a copy of the userdata partition on my computer (the crypted partition), then I wiped my phone, I flashed the DM Verify Disabler and then Magisk via TWRP, until then, no problem, I was root but with an empty phone.
There, I uploaded my copy of userdata partition into my S8, I boot the system and always the same error of integrity verification failed...
Now, my phone works always good (I flash the stock ROM via ODIN) but I haven't yet the root.
Is there a way to root the S8 without lost the datas ? A kind of APK or something else ?
Kind regards,
Lau

You need to reflash twrp in odin and boot into recovery (TWRP) before the phone boots the system. Id uncheck auto reset in odin and when its done flashing twrp again boot right into it. From there you want to select to keep the system read only, and then flash the DM Verity Disabler. After thats done flashing, your phone should boot up normally without seeing the integrity failed message. Its important that you boot right into twrp (recovery) after odin flashes it, if not you need to reflash twrp in odin until you successfully get into recovery before it boots your system.
I just tried 2 times this procedure, when I flash the no-verity-opt-encrypt-5.1, I have several error messages like Failed to mount '/data' (Invalid argument) or Unable to recreate /data/media folder or Unable to mount storage and Unable to mount /data/media/TWRP/.twrps.
When I boot up the phone, I have the same error of integrity failed message and I have to flash a stock system and boot img

You have to wipe data otherwise it won't boot, there's no way round this unfortunately

Previous poster is correct. Wipe>Format data>yes> in twrp then you should be good to go.

[BUG][SOLVED][WORKAROUND] TWRP starts with no menu, runs script, crashes, repeat (Axon 7 mini)

Hello,
im new to this Forum. I try my best to give all the information i have.
What happened?
I tried to install the project /e/ os on my axon 7 mini. First I unlocked my phone with tuliptool in edl mode. I found the twrp recovery-image for my device in this guide (https://www.getdroidtips.com/root-twrp-zte-axon-7-mini-magisk/#Download-Files) flashed it with tuliptool to the recovery partition and it worked. But it broke my stock android rom. I only can boot intro twrp - i cant boot android (only shows zte android title screen). Then i installed the unofficial /e/ port for my device with twrp and it worked. Then i thought i could unroot my phone with tuliptool (i dont know why atm i thougt it will be a good idea) so i ran tupliptool lock unlock and my device was locked again. Now i only can access twrp so i undo the locking. After wiping the data partition with twrp, /e/ startet again. Then i thought that wiping the data partition would solve the issiue with not loading /e/ while locked, therefore i gave it an other try. Locking my phone again, wiping partition with twrp and... nothing. So i gave up and wanted to use my phone again so i unlocked it again.
Whats the problem?
Now I only can access twrp, but it wont show the menu. It just autostarts a script and there are no buttons. The script failes after ~10 seconds and the device crashes (error message below). It trys to boot up but fails, so it loads into recovery -> starts twrp -> runs this script -> crashes and so on. Now i cant do anything. It reboots all the time.
What can I do?
As said, twrp starts but with no menu. I have access to edl mode so i rewrote the recovery partition. This does not change anything. I can access my device with adb while it loads twrp. I have a time window about 10-15 seconds until it reboots. Fastboot does not work. (Not available or locked on Axon 7 mini?) If i try "adb reboot bootloader" my phone just reboots into android (well it did before flashing, now its stuck in the loop.) From searching this forum i think i should reformat the partitions, but i dont know how because i dont have access to the twrp menu. If you need more informations like a dump or something, tell me how to do it.
The Error:
As i dont know how i could dump it from my phone to my PC, i had to manual type the Error here...
$Begin
Data successfully decrypted, new block device: '/dev/block/dm-0'
Updating partition details...
...done
Unable to mount storage
Successfully decrypted with default password.
Updating partition details...
...done

Running Recovery Commands
Failed to mount '/data' (Invalid argument)
Formatting Cache using make_ext4fs...
Done processing script file
Failed to mount '/data' (Invalid argument)
Failed to mount '/data' (Invalid argument)
$end
This runs fast until "Done processing script file". There it waits for ~3 Seconds. Then the last two lines show up and it crashes immediately.
Ok i found a solution - it worked for me but i dont know why. Its not intuitive but hey, its a workaround.
The problem was twrp couldnt startup anymore because the data partition was currupted (not confirmed, but i guess it was currupted). If you follow any guide, they tell you to go to wipe data inside of twrp and wipe (and reformat) the partition. This wont work in this case, because the corrupted partition causes twrp to crash. Its the script in the post above.
To fix this i used adb while twrp was starting up
Code:
adb shell recovery --wipe_data
This alone wouldnt solve the issue, but it will buy some time. After twrp loads again, you will see the main menu of twrp for a couple of seconds. The time you have on the menu is very limited (5 seconds max) before the script that will crash twrp starts executing. In this time window i managed to set twrp to write mode and initiated the wipe of /data. If you get this far, both scrips (wipe data and open recovery script) will execute, the screen will switch between both of them very fast. After a few seconds it will crash again, but the wipe data script could reformat the data partition properly. After this twrp will work like normal.
I don't know if this problem is specific to my device or model. I dont know if this is recreatable. Im glad i fixed it after five long days, im not willing to sacrifice my device again. I dont know if this is a twrp bug or what happened exactly. If anyone had a clue or needs more informations i will provide them. At least I found a workaround.
