Internal storage error

THX for the fast error fixes, but the internal storage error is still exist (in chrome /sdcard doesn't exist or "cannot access /sdcard". The integrated file explorer within the rom itself cannot open (no error message), when connect the tablet to the computer, no internal storage space). In TWRP when connect, the internal storage exist, you can copy files.
[Miscellaneous Android Development] SaberShip:
Thanks for the info. Strange, mine seems to work just fine. Iv'e tried from Chrome, built in storage manager, other storage managers, and over USB. They all seem to work fine for me.

Have you ever wiped data AND internal storage with TWRP? Perhaps the TWRP I ported isn't properly formatting the internal storage, this is one thing I haven't done since having stock on my tablet. I'll try it soon.
[Miscellaneous Android Development] szelezola:
Yes I do, format-wipe everything (internal storage to). I use the TWRP in your OP message.
[Miscellaneous Android Development] freddie2000:
I have made a dirty flash of this new rom, wiping system, cache and dalvik only, and internal storage is working well now. I can download and archive files with chrome without problem. Thank you very much SaberShip.
[Miscellaneous Android Development] Srisri7:
Yeah I am also waiting for oreo go. Nougat takes too much ram and also I am on resurrection remix marshmallow rom I think it is more customisable and speaker output is also very good

---------- Post added at 06:59 PM ---------- Previous post was at 06:35 PM ----------

Please make resurrection remix.. Because it is the most customisable rom I think so far..
[Miscellaneous Android Development] coucout:
I've reinstalled the "revision 2" and now the /sdcard is well mounted and the tablete is usable, so apps like chrome or EZ Pdf reader and integrated file explorer works well. For Folder Sync use, I have to give it root permissions.

I can insert a Sd Card. It is seen under integrated File Explorer but not in ES File Explorer as it's path seem to be not conventionnal. So, other applications that relies on conventionnal path doesn't see this new inserted SdCard. Indeed, this sd card is seen under "storage" parameter like the fourth card after the 3 others that are corrupted
[Miscellaneous Android Development] SaberShip:
Thanks, I will try to recreate some of these storage bugs soon, however, I may be busy over the next week so it may be a week or so before I can get them fixed.
[Miscellaneous Android Development] coucout:
Other thing, Google Sheets doesn't work too (when i open it, it refuse to show documents because a problem with synchronisation. I suspect a problem with storage too. Same thing with Google Docs.

But Google Drive works (content of my drive is displayed)
[Miscellaneous Android Development] coucout:
Oops Google sheets and Google docs work now. But i have done nothing...

If it make the same thing again, i will post another message.
[Miscellaneous Android Development] SaberShip:
After doing some digging, I believe the storage bugs to be due to the fact that you may have wiped "Internal Storage" with my TWRP 3.1. In android there are 2 kinds of internal storage: Physical and Emulated. Lenovo's stock firmware uses physical storage, as well as some of the custom roms out there for this device. However, unknown to me at the time I believe the TWRP 3.1 that I have ported to the A7600-F defaults to emulated Internal Storage.

This means that those of you who have wiped/formatted "Internal Storage" with my TWRP need a special version of this rom that expects the emulated internal storage mode instead of physical. The only way I currently know of to get back to a physical internal storage is to use a tool like SP-flash and go back to Stock Lenovo 4.x, root, then install TWRP and never wipe Internal Storage. :eek: (If you have another way let me know)

I'll be releasing a separate boot.img for this ROM soon that you can flash to the /boot partition using my TWRP that should fix the storage problem for those who have wiped Internal Storage in my 3.1 TWRP.
[Miscellaneous Android Development] SaberShip:
Posted new internal storage fix

Check the OP for a new boot.img file. Flash it with TWRP to boot only if you are having issues with internal storage.

Hope this helps!
[Miscellaneous Android Development] szelezola:
Thank you for taking the time to fix it (internal sd). I can check it out tomorrow morning, because I left the tablet in the workplace...
[Miscellaneous Android Development] szelezola:

I have some problems with wifi. It came and went totally randomly so i did re-install OS if it the issue with wifi had something to do with any apps i had installed so i wanted to wash memory so to say.

Anyway, i`m very impressed of your workSaberShip !!! It`s great now !! I was going to buy a new one but now it`s not neccesery.

However i was also having this problem with micro sd. I have an 32gb and i can see theres is 3 corrupt an 1 small so i also have this bug so it`s neccesery to do that fix immeditily while i keeping doing this.

Can some plz make an easy guide how to do like:

1.do this

2.do that

and so on.

You`ll have to forgive an middle-age,nooby,owerweight swede.........that i don`t get to complicated instructions.

[Miscellaneous Android Development] SaberShip:
Have you installed the emulated storage fix from the OP?
[Miscellaneous Android Development] lokiz1:
Hello ,

So, at least i have installed TWRP 3.1.0.0

I have for the moment two questions.

1. Which boxes do you fill in when you wipe in ,advanced wipe when in recovery mode ? Is it enough with

"Dalvik/ART cache" , "System" , "Cache" ???

2. Can i please have an simly guidence how to install "Emulated Storage Fix" ? After i`ve download that one it seems to look like an .bin file. I`ve tried in recovery mode ( push volume up + On/off button ) but there i cant find a way to manage an install of that file.

Thanx !!

I'm having the Corrupt SD card problem. It happens with both AIM and Lineage 14 even after flashing your .img to Boot. I have a Nandroid backup of the tablet stock rom but I don't think it fixes the internal storage issues. How do I flash the stock rom with SP Tools? I'd rather have my storage working again.

EDIT: I flashed the stock rom with SP Tools (twice) and internal storage started working again. Then when I flash either Lineage 14 or AIM v2, internal storage breaks again (corrupt sd cards). I tried with both your TWRP and the one on CM13 port post, didn't format Internal Memory after flashing the stock rom. Same problem. The only way internal storage works is by using both CM13 post's TWRP and CM13.

BTW here's the stock rom link I used, if anyone needs it:

Corrupt storage

I had the same problem with both ROMs. I started by going to AIM from Lenovo stock, using the "updated" TWRP posted in this thread. To install your TWRP I installed Kingo Root (maybe not everyones top choice, but this was only to replace the stock Recovery, then it gets wiped anyway). Once rooted I used Flashify to flash the TWRP Recovery image provided early in the thread.

After installing and booting up the AIM ROM I looked in Settings > Storage ... it show several corrupted SD storage volumes. On the AIM ROM the Files app just immediately crashes. I then tried your Lineage ROM and I was at least able to use the Files app to browse local storage, but in Settings > Storage I still see corrupt SD storage. In AIM I cannot save a file from the Browser app, it crashes. I also seem to not be able to browse storage using a computer connected via USB (even when set to MTP). I'm going to have to SP Tools back to Lenovo stock for a usable system...but it would be great to see these ROMs with storage working. Thanks for all the hard work on it.

[MENTION=8278032]SaberShip[/MENTION] Thanks for this port! Installed it yesterday and must say it's performing much much better than a Marshmallow port I installed some time ago. Super appreciated that you share your work here. ROM is quite customizable in settings. Will see how it stands when I have used it a little bit longer.
[Miscellaneous Android Development] Boban1510:

[Miscellaneous Android Development] Bobinek15:

[Miscellaneous Android Development] Hemuli:

[Miscellaneous Android Development] BiG_FooT:
Did have time to play around with this ROM for a little bit longer. Must say it's still going strong! After flashing the storage fix WiFi is also ok again. Again thanks [MENTION=8278032]SaberShip[/MENTION] for sharing this ROM. It's a stayer for my Tablet.
[Miscellaneous Android Development] BiG_FooT:
Agree, think that this is the best way to make the ROM work as it should with internal storage. If facing issues re-flash stock, root, flash TWRP (and don't wipe internal storage). At last flash this great ROM.

[Miscellaneous Android Development] Teleportist:
Hi SaberShip,

Thanks for your hard work on this. It's totally rejuvenated my old A7600-F, which had been abandoned by Levono, development wise.

Good products, bad ongoing support!

I have the SD storage issue, and am yet to try the fix mentioned above (thanks to Looney555 too), but I was able to cure the Chrome SDcard access issue

by revoking Chrome's storage permission, then allowing it again.

The only other problem I have is that my favorite game (C.A.T.S.), which worked flawlessly on the stock ROM, now freezes during the intro (after inputting your name).

This may possibly be due to the aforementioned SDcard issue (will report after the fix), but if you've any other ideas why this is happening it would be appreciated please.

Have installed google Play Games (required). Could a larger version of GAPPS be needed?

Here's the a link to the game

https://play.google.com/store/apps/details?id=com.zeptolab.cats.google&hl=en

Thanks
[Miscellaneous Android Development] BiG_FooT:
Hi, I suggest that you try the SD card fix. Will probably fix your issue as I faced similar behavior with apps not running as expected. After flashing the fix my good old tablet is working perfectly fine.

With me everything is fine. At first it had some problems with my sdcard but with a fix a had for my other tablet it is now working great. Music playing gives no problems. The front camera is indeed upside down but than can be solved by my software. The only thing missing is otg usb but I think that is a hardware problem.

Thanks for giving my old tablet a new life
[Miscellaneous Android Development] SaberShip:
Every Custom ROM that I have had experience with for more than a month on the A7600-F seems to have a similar wifi turnoff issue. If you know of any custom ROM (6.0+) for A7600-F that for sure doesnt have this issue, let me know, i'll look into file differences.
[Miscellaneous Android Development] BiG_FooT:
I cannot help you with that because I don't know how to port ROMs. But I must say that I'm still super happy with the AIM 7.1.2 ROM. WiFi issue is a bit annoying but worth the step from KitKat to Nougat. Thanks for sharing this ROM!
[Miscellaneous Android Development] PT400C:
Hey,

I also have to share my thanks :) This port is awesome. But I've got one annoying and breaking problem. I did everything like Looney555 told us to do, but the tablet shows off only 100 MB of 14 GB space. Is this due to I do not have a SD-card? Or does this not matter? Any idea?

We are missing /boot mount point in our fstab. recovery.fstab points /boot to /dev/bootimg, but at least Magisk zip installer can't find what it is looking for. Magisk is able to patch the boot image if it is hand-fed in Magisk Manager.

How could we mount /boot properly? Do we know if it's any of the following is our /boot:

/dev/block/mmcblk0p1

/dev/block/mmcblk0p4

/dev/block/mmcblk0p5

It's possible to install Magisk by patching the boot.img in Magisk Manager, but it's a little slow process.

There are no more custom roms for A7600-F unless someone ports them.

Great stuff. I did it with the twrp image and rom and gapps rars in a folder i copied from my pc to the android downloads folder. I found i could navigate to it after installing twrp with flashify and run the rar files from there. I did however then realise i forgot to copy the fix boot image. :silly:

This ofcourse meant my pc no longer recognised it so i had to order a cheap 32gig card and reader for a tenner from amazon but with quick prime delivery it's now working great.

I have the internal storage working fine with my SD card appear corrupted after few seconds. I tried to format using internal or extended without a better result.

I have tested the SD card on another tablet with success so it is not a SD Card issue.

Do you have any idea to get it working ?
