[Q] HELP E977 can't access Storage

[SOLVED] I've founded a flashable zip with the Stock rom. Flashed it, but still stucked on boot logo. Then i flashed BAM rom again and that's it!
The .zip file fixed all the firmware issues, but the system couldn't boot (maybe cus my phone is an e977 an the .zip is for e975) so i just instaled another ROM
Here is the zip for fixing IMEI, phone signal, accelerometer, wifi, bluetoth or (maybe) any other issue that may happen! (In case someone, somewhere, some time need it)
http://forum.xda-developers.com/showthread.php?t=2407489
U just need to backup your stuff (apps, music, photos...) install the zip, then install your favorite custom rom again and restore your stuff!
Hey guys. First of all, forgive me for any spelling mistakes, i'm Brazilian.
I've been passing thru a lot of problems with my E977 in the last few days. I've accidentaly formated the firmware in CWM (that was stupid, i know). After that, i've lost my connection signal, wifi, bluetooth and also the acelerometer.
Flashed a ZIP with the correct modem and the conections came back! But i just couldn't make the acelerometer work again(tried 5 diferent ROMs, including stock)
So, i came back to Stock by flashing the correct .KDZ but then i've got stuck on LG's Boot Logo.
Then i used the "teenyBin" and after google's boot logo the screen just turned off (???).
So i flashed latest CWM and from there i flashed BAM nightly ROM (TWRP was giving me an error) and now i can boot. BUT LOST THE CONECTIONS AGAIN!!!! And the acelerometer still not working.
I was trying to flash the modem .zip again, so i can at least use my cellphone, but then i discovered that my USB Storage also doesnt work. (Device is detected, but windows can't acces storage)
Opened the file manager and it gave me an error saying that the folder couldn't be found.
Gone in to settings and changed to root properties. After that i could open the file manager and noticed that the /sdcard folder is missing! And there is nothing under the folder "storage/emulated"
After that i tried to push the file with ADB, but it gave me a permition error.
Tried to push in recovery then, but ADB cant conect with my phone when it is using CWM recovery, only TWRP
So, i need to fix the internal storage issue AND the acelerometer issue.
I also have tried to flash KDZ again, but now LG's software can't conect with the phone (i think it's cus i removed the stock recovery).
Please somebody help me, i've been trying to fix this **** for the last 3 days!!!!!
[EDIT] Came back to TWRP and flashed the modem .zip thru sideload. No results. It's not the same problem as before
[EDIT²] I've lost my IMEI. What now?
Oh no! Your problem is the biggest problem I ever seen on xda.I think LG support is last option.

[Q] MIUI Rom gone wrong

okay so heres what happened.
I have an international htc one x that is indeed rooted with no roms installed.
I did create a back up and then tried to install the MIUI rom (but I dont really know where that is on my phone. I know I made one with rom manager. I dont have any backups on my computer though)
It worked, however, it didnt have wifi or data signals so i went back to try again.
I opened my bootloader screen. For the record, it is unlocked and hboot is version 1.73 if that helps.
I wiped cashe/data/delvic everything and even factory reset and installed the MIUI RD rom now hoping it would have a difference.
The darn thing got stuck on the MIUI bootloader for hours.
I did the same thing again a few times, sometimes in different orders and then it passed on and another screen came saying 'starting apps'. That got stuck for hours too.
Now I don't have any other roms on my phone, just the MIUI RD. The original miui just vanished too, i dont see it anymore. Also, when I put my USB wire to the phone and connect it to the pc, I cant transfer newer files into it. So this is all I have access to on my phone apparently.
I tried flashing a boot.img and a couple kernels but no luck. I've been trying to do this for all day and this is my first time so I don't know much about it.
I've been googling and somethings say to open cmd and type but i keep getting 'fastboot is not recognized as an internal or external command'
Currently, its not stuck at either the MIUI screen or the Starting Apps. but just the HTC logo screen and not going past.
I don't really want to install any new roms considering i've worked really hard to get this to work and I really want it now more so.
How do i fix this? I want to use this rom.
flash philz recovery (http://forum.xda-developers.com/showthread.php?t=2240646), usb mounting should work on that, then:
steps to install ROM
1. bootloader version should be 1.3x
2. copy ROM to SD Card
3. copy boot.img INCLUDED in the ROM zip to fastboot folder
4. flash the boot.img in fastboot
5. in recovery, wipe system/data/cache/everything
6. flash rom
7. restart
but how exactly do i put it on my phone? my computer isnt detecting my phone when i connect it? im sorry im not exactly an expert on this.
Go to recovery - mounts and storage - hook up the usb cable - tap the last option in the mounts and storage list and wait a few minutes. It won't be mounted instantly
ok i flashed the philtz recovery but when i flash the boot.img it says:
Finding update package
Opening update package
Installing update
installation aborted
for reference: http://forum.xda-developers.com/showthread.php?t=1957490
thats the rom i used and i flashed the boot.img flasher thats right above the download link
edit: also i tried just flashing the rom again and im still stuck on the HTC screen.
its not even going to the miui screen or starting apps anymore. :[
Boot.img must be flashed via fastboot. Not via recovery !
ok, i looked up how to fastboot, downloaded sdk files and i moved the boot.img into the fastboot folder and i opened command prompt there and wrote fastboot flash boot boot.img but i keep getting:
'fastboot is not recognized as an internal or external command'
what did i miss?
EDIT: ok, so the fastboot folder i got from the page didnt work so i used a different fastboot folder, dragged the .boot there and now it worked! finally passed the screen and wifi is connecting!
thank you!
Good, thanks to @tomascus. He summed it up real nice
Cheers

Desperate cry for help

The title might sound a bit extreme but hear me out. Earlier I was updating Havoc-OS to the latest June 12th, 2019 build. Upon flashing it within the TWRP recovery it asked to update the firmware. The firmware that it required was V10.3.1.0.PEIMIXM. I flashed fw_whyred_miui_HMNote5Global_V10.3.1.0.PEIMIXM_d4d2c9f2aa_9.0 from the website where all of the firmwares are managed, but ever since I did this my recovery has then broken itself (ARB as well? Give me a second..). Every time I go into TWRP and want to transfer files, there is no way for me to transfer files from my phone to the computer and vice versa. MTP is enabled but I just cannot transfer files what so ever. I tried to reflash TWRP, update to the latest version and it still has not worked. One thing I have noticed while flashing TWRP within Fastboot was that it didn't require me to use the dummy.img in order to flash via fastboot which I thought was strange, knowing that my phone has ARB Level: 4. I have since then used Mi Flash tool to get the phone working again but every time I try to flash TWRP, MTP still will not enable and I have no idea what to do. I'm so scared as to what to do next because I don't know what to do. Please any help or suggestions?

Go to developer options, disable USB debugging and then enable it again connected to pc and wait that a pop-up appears on device screen, tap on always allow, then within adb/fastboot folder try to send device to recovery with "adb reboot recovery" see if was solved, if not then try erasing recovery partition through fastboot with "fastboot erase recovery" then flash TWRP again as usually, disconnect from pc before to boot to it, then in TWRP connect to pc and wait that pc recognice it.
If the issue persists you can uninstall and delete all the files related with drivers on pc directories and then make again a clean install also wiping cache/dalvik onto your device.
It's because u used the twrp meant for oreo firmware. It is incompatibile with new pie fw, you must flash latest twrp for example twrp 3.3.1 using fastboot. Use adb commands: 1.adb,2.adb shell,3.adb fastboot boot (location of the twrp 3.3.1) for example C:\twrp.... .img and then from the recovery flash twrp 3.3.1 as recovery.
i had same problem.
i installed latest global stable miui_HMNote5Global_V10.3.1.0.PEIMIXM_d4d 2c9f2aa_9.0 rom from sd card.
MTP is working properly.
but there is problem for me after that.
This is strange problem.
after installing miui rom twrp recovery uninstalls automatically after reboot,when install twrp via boot it encrypts twrp.
can anyone help me?
my problem is-
after all this if i try to install custom rom(from sd card) it says corrupt file or error 7 ,i tried to flash 3-4 different rom.
EDIT: my problem solved after installing this twrp https://androidfilehost.com/?fid=6006931924117884758 (from AOSP ext pie rom thread)

Swiped "allow modifications" in TWRP, now bootloop

First unlocked the phone.
Then flashed and booted to twrp-3.3.1-2-grus-20190609.img
I believe here I swiped "allow modifications".
Then installed:
no-verity-opt-encrypt-6.0.zip
magisk-v19.3.zip
Rebooted and... Stuck on boot logo, then restarts back to recovery.
Is there a way to solve this without losing user data? I have a pattern/fingerprint set and some important data that could not be backed up (like google authenticator).
Any way to restore system perhaps?
Short update...
I have downloaded latest stock ROM for Miflash. Extracted it and did this:
Code:
fastboot flash system system.img
After this it booted fine, but none of sensors work: no proximity, no camera, no wifi.
Mobile data works, but no calls.
I have tried both roms, Global and Europe.
If I reboot it, it won't boot, goes to stock recovery, not OS.
However, if I boot to TWRP in fastboot:
Code:
fastboot boot twrp-3.3.1-2-grus-20190609.img
It actually boots in to OS again. Still no sensors.
I have tried to wipe everything and flash a fresh ROM via EDL mode and Miflash, but it asks me to log in to xiaomi account and then says I am not authorized.
So the device is kinda bricked now.
What next? Can I flash some other partition to get this going again?
Same problem here ? you did it ?

Same problem here ! you did it ?
I could not get it working.
When I flashed system.img, wifi and sensors did not work.
This could be solved by flashing persist.img, but that partition is write protected.
I could not reflash the ROM with MiFlash because it asks to log in and says my account is not authorized.
However I searched around and found a cracked version of MiFlash on GSM developers forum that actually worked (in fastboot mode, not EDL).
I have reflashed it completely and, while I lost all of data, wifi and sensors work.
I then tried to restore only data from backup, but it crashed the system again.
So I had to reflash it again and install, configure and restore data for over 100 apps, manually. Two full days wasted.
I have looked for a reliable way of restoring individual apps and data from TWRP backup, but there seems to be no convenient, reliable and free way. Possible (not easy) with some linux scripting, but it's not how I roll.
But hey, I have root and adaway now, so no ads. Worth it.

Why did you flashed no-verity-opt-encrypt-6.0.zip ?

Can not write on EMMC flash on a Vodafone Smart Tab 4 tablet

I have a problem with my tablet. When I try to flash a rom I get a message that the flashing was successful. After a restart I see that nothing has changed. The flashing did not work.What's also weird is that when I try to transfer a rom via USB in TWRP, it ends without an error and the new rom is displayed normally in TWRP. But if I restart the device, the new rom is not visible anymore. This only happens when I try to copy a rom into the internal memory
What's also funny is that when I try to transfer a rom via USB in TWRP, it ends without an error and the new rom is displayed normally in TWRP. But if I restart the device, the new rom is not visible anymore. This only happens when I try to compile a rom in the internal memory of the tablet. If I copy the rom to the MicroSD card it works fine and the data is preserved even after restarting.
I have the same problem when I try to flash the stock rom via SP Flash Tool. I get a message that the flashing was successful, but when I start the tablet nothing has changed. For example, I tried to flash the stock recovery but every time I try to start it, I can only get into TWRP.It looks like I can't write to the internal memory of the tablet at all.
Maybe someone knows a solution for this problem
