Question (Newbie) HELP! Lenovo Phab Plus PB1-770M (E: can't mount /cache) Stuck in recovery - Lenovo Phab Plus

Sorry if this will be considered spam, but I needed to repost here instead.
I loaded the recovery mode and attempted to load TWRP without knowing how to activate Fastboot. Unfortunately, I had wiped the cache partition and rebooted the phone.
It resulted in kicking itself into recovery after a failed boot-up into android, as string of E: can't mount /cache showed. I tried to wipe data/facctory reset and try again but I'm stuck.
If anyone has a possible solution/suggestion, I'm open to do it.

i know its too late to answer your question, but i will answer for anyone who comes here next...
First: you have rebooted your phone before it finish the wipe data order, this caused your problem.
Second: just make another wipe data/cache... but wait for about 30-50 Minutes till its done ... yeah it takes that long

nahh no problem dude, i know what its like to soft brick your phone so ill help to the best of my knowledge. http://forum.xda-developers.com/showthread.php?t=1126631 it's here. on teddy's first post. so pretty much, you would download it, put it onto your phone which is the /sdcard part, then 'flash it' (fancy word for install) by going into cwm mode, and going to install .zip from sd card, find the cwm3xx file at the bottom, then flash it. THEN it'll pop up a 'new' cwm mode and from there factory reset, reset the cache, go to advance and erace dalvil cahe and check your mounts, then flash the new rom..if your trying to flash a rom that is lol. if you have questions post away!
oh and i think this should go in the general section.
Im stuck on the Sidekick/Tmobile/Samsung screen now and it will vibrate once, then 3 times then wait 3 seconds then vibrate once then 3 times etc.. WHy?? is it bricked now?

Yeahh that happened to me too, and i had to odin, but it wouldnt read the phone so i had to uninstall and reinstall the drivers on my comp. then go into download mode and odin.
Yup, that kept happening to me.. Im gonna try and install this cmw now.. By the way, do i still have to check the mounts and storage because i've successfully installed the maximus rom gingerclone. Do i have to check mounts and storage everytime i need to flash a rom, if so what should they be, as far as Data, sd card, cache, and system etc..?

no you do not have to check!
Yes you do need to check! Not checking is what makes you soft-brick.
it should read:
System: Unmount
Data: Unmount
Cache: Unmount
Anything else isn't an issue.
Don't worry about the errors reading that cache file, they happen to everyone, it's part of the kernel.

I am getting this error on my sidekick 4G
E:format_volume: make extf4fs failed on /dev/block/mmcblk0p2
Formatting /sdcard/.android_secure
i was trying to upgrade to Lite'ning ROM but it gave me this error, i did already ODIN to stock and it did not work and what i mean by it did not worked i did get to stock and started from scratch but still getting the same errror..... any other suggestions?
Don't worry about that error, that just means that you don't have an android secure partition on your sdcard. nothing to worry about.
I don't see why red CWM would be any different from Orange CWM in having to check mounts... I always check my mounts, and have always had to.
well u say not to worry but i can't update the rom to the lightning rom b/c i cannot factory reset, if i don't factory reset, phone bricks
You don't have to factory reset, just make sure you check your mounts. that's why it's bricking.
ok... so what are the mounts?
Please see thread: [RECOVERY] CWM for the SK4G. Enjoy!

You will find in the OP (original post #1) there is a step:
CWM Final
http://www.krylon360.com/file_host/sk4g/update.zip
Place in the root of your SD.
After your in clockwork mod recovery (orange) (and have downloaded the update.zip to sd card) make the selection: -apply sdcard:update.zip (this will load cwm again (red cwm)
Now: reattempt!

Undo Format Data?

I am a relatively new android user but do enjoy flashing roms, kernels etc
My problems began when i was trying to flash a new rom on my Nexus 5
I was trying to flash this rom http://forum.xda-developers.com/showthread.php?t=2655722 but despite doing a factory reset and wiping the dalvik cache and cache it refused to boot in to the new rom
I tried to flash the rom multiple times but without success, eventually when trying to boot into recovery to try again i was greeted with an unthemed TWRP recovery asking for a password despite the fact that i had a custom theme and multirom installed I tried to proceed anyways but was greeted with E: unable to mount storage
In desperation i tried to solve this problem and found this
UsoftTech :: WwW.UsoftTech.CoM ::
TWRP asking for password
After unboxing my Nexus 5, here's what I did:
1. Booted into bootloader
2. fastboot oem unlock
3. Flashed TWRP v2.6.3.0
4. Booted to recovery
The screen that greeted me says "Please Enter Your Password".
I can hit the cancel button below this which takes me to the normal TWRP screen. I then pushed SuperSU to /sdcard, but when I flash it it fails because it's unable to mount /cache or storage.
When I reboot to the system, it takes an awfully long time (approximately 30s) to progress past the "Google" screen, and then it just seems to sit on the booting animation forever.
Any help?
EDIT: Solved my own problem.
Hit cancel at the password screen, then go into Wipe and then do a factory reset by swiping. Then go back into Wipe and press the 'Format data' button. You have to type 'Yes', and it will take a few seconds. After that everything should work normally.

I now fear that i maybe without both a rom and all my files such as my music that was stored on my phone.
Is there any way for me to undo the damage i may have done to to my phone?
You can't recover the data. But you can push files over with ADB.

Nexus 5 "Google Logo" Bootloop - Not Power Button Related - Please Help!!!

Hello all,
First time posting, long time lurker. Everybody here at XDA has been exceptionally helpful with every Android device I've owned. Whether I've had technical issues, or just wanted to try out some new ROM's or apps. I just wanted to take a second to thank you all before I got started with this post.
I've been pulling my hair out over this Nexus 5. It is my wife's phone that she never rooted, unlocked, or anything outside of generic user space.
I looked all over XDA and the web looking for solutions to this issue, but have been unsuccessful. Below is an overview of what's going on with my device.
___________________________________________
1: Nexus 5 repeatedly bootloops at initial Google logo
2: Bootloader locked - I can unlock it with fastboot oem unlock but it is reverted to locked at each restart.
3: Recovery mode bootloops every time cache is touched - Every time I attempt to sideload images or wipe cache recovery bootloops. This makes it impossible to flash factory images in recovery.
4: Problem seems to be with the cache - In fastboot I can wipe userdata, but when it gets to wiping cache I get an error.
5: Yes I have tried re imaging with factory images, flashing TWRP (doesn't take, ADB wasn't set to on before this happened and I think the bootloader unlock isn't really working, but Im not sure,) flashing stock cache, flashing stock bootloader etc.
Any idea's guys? This is my last attempt to fix before I just take the Nexus apart so I don't waste anymore time on it. I would be happy if I could get any functionality whatsoever.
Thanks so much,
Nathan
:Update:
I was able to boot into TWRP with fastboot boot recovery twrp.img.
Trying my luck here, it seems to have been able to wipe the cache, but not mount /data.
Unable to mount storage
Failed to mount /data (invalid argument)

Encrypting device gone wrong, android and recovery broken now, seems softbricked?

So, I made a big mistake.
I tried to encrypt my device, but it got stuck at 100%, so i rebooted it and now it's completely messed up.
When i boot it, it asks me for a password, when i enter it, it says decryption unsuccesful and my data is corrupt.
It gives me the option to reset the phone, which is fine, but it reboots the phone into recovery.
But i can't get into recovery, i can't read it properly but as far as i understand it fails to mount /data 5-ish times and then reboots again and tries to boot android again, bringing me to the password screen once again.
I don't care about data, i have backups, but i just want my phone working again.
TL : DR: phone boots, asks password, says data is corrupted, reset phone, goes into recovery, fails to mount partition, reboots, back to ask password.
If i have to do something in ADB let me know, i'm far from good with it but i can at least get it working...
Edit: RECOVERY WORKS! I got that one working again! Problem is that it still can't mount the /data partition so i can't seem to reset/wipe the phone properly.
Edit 2: Device is up and running again. I re-flashed the recovery via the bootloader and ADB, did a full wipe with the recovery because the re-flash fixed it and the wipe fixed the mount problem. After the /data partition could finally be mounted again i just flashed a ROM as usual with gapps and problem solved!
The microSD was broken too but after formatting that with a PC the phone could use it properly again. Did take a few tries tho, no idea why.

Galaxy S7 930f can't access twrp

Hello, thanks for your help.
It seems I bricked my galaxy s7 while trying to format the /data partition.
I installed TWRP 3.2 and a custom rom, and everything went smoothly until then.
I tried installing an audio mod which throwed a " can't mount /data" error, searching for solutions I read that formatting the data partition to fat and back to ext4 should solve the problem, I tried formatting it to fat with TWRP, however on the first try I got a message that it suceeded, followed by a message that /data could not be mounted, TWRP seemed to be still working (there was no reboot button or any other buttons, just a "working" bar). After giving the phone 3 hours I decided to restart it, now I can't access TWRP; it stays on it's "splashcreen", and of course the phone won't boot.
I'm having a rough time with this so I will appreciate it a lot if you can help me.
Thank you.
Boot to download mode, flash stock firmware using Odin, then retry the TWRP installation.
For wiping data, you have to make sure you use the wipe option that makes you type out 'yes' to wipe, the other factory wipe methods don't actually properly wipe the partition.
iirc you also then need to flash the dm no verity zip from the TWRP thread.
Bro you didn't have to do anything but just formating the phone in the first place. Aassuming you're on oreo , it happens to a lot of people and myself, after flashing a kernel twrp was unable to munt data, all i had to do is a data format in twrp that fixed the problem .
