This guide works only if your WiFi is dropping and can't get any signal but you DO have IMEI.
Why this happens?
As this is an A/B device TWRP stores it's logs on /persist/cache/recovery, filling up this directory and collapsing persist making WiFi/Mobile signal reset.
How is it solved?
Simply deleting these logs inside /persist/cache/recovery they are named "log" and "last_log". Erase these logs, reboot and solved!!
Once you recover your signal make a backup of efs/persist and save it in a safe place to prevent this from happening again.
Please comment if you have any issues

I'll leave a screenshot from the directory
I will post update for TWRP that should fix this bug asap too, but for now for the users effected, definitely do the above to fix [emoji6]
Dude, you are my friggin' hero. I am on a g7, but it appears to have worked.
Thank you!
I am in a bit of a pickle, I was sent a link to this post... So, my wifi does work, I even tried to flash a stock recovery for my model of g6. It however does not read my sim card. Before I did all this it was working with my carrier, google fi. I went into this folder. (I also did remember to mount persist) and it does not have a cache folder to begin with. So I am still pretty stuck. Any ideas? It's a moto g6 xt1925-13. Id also like to note it says baseband <none>. I also goofed and didn't make a backup like I should of.

Hello, do you have IMEI?
Most probably not so you need to flash the latest pie stock rom from your channel. The complete rom and via fastboot, I believe you already have your stock rom, however it can be found on lonlinet mirrors and the fastboot commands can be found here on xda on a thread named going back to stock.
If you still have trouble don't hesitate on asking again

Hey just an update, I was using lolinet, but I was downloading the retail rom, turns out I needed retar. All is restored. NEXT TIME ill back up!
Hello,
IMEI and WiFi now work properly.
Thank you very much.
Is this fix only relevant if the persist partition is full? My wifi mostly works, but drops out ~8 times a day. Most of the time I can fix it by turning wifi off, waiting ~5 minutes, then turning it back on again. I have an IMEI and my SIM card works fine. I tried deleting the log files as per the first post, but it didn't fix the wifi dropouts. However, before doing this my partition was not full:
Code:

As u said, this is if persist is filled up. If it is then you wont be able to use wifi at all, it would only connect for a few seconds so you def have smth else going on, try flashing stock again

Thank you for the reply. Yeah, I tried a bunch of other things… flashing stock, flashing a backup of EFS and persist, erasing modemst1 and modemst2, but it still keeps dropping out unfortunately.

Hi
Since ever I noticed a weird thing on XMP: /cache partition is always almost empty.
Yes, I checked many times during a long time, it's like is never used.
Code:
$ df
/cache 101.5M 1.1M 100.4M 4096
I have only an empty lost+found dir and two files under recovery dir:
Code:
# ls
-rw-r--r-- root root 105 2012-12-15 02:07 last_install
-rw-r----- root root 3214 2012-12-22 10:36 last_log
For example, in a previous phone /cache was actively used by market for downloading packages before installing them.
Here on XMP I can't upgrade also small packages (40+ megs free on /data) 'cause they're downloaded in /data and fill it before being upgraded, and /cache remains always empty.
In addition, if for some reason playstore crashes while downloading a big app (30megs+), it leaves my /data (almost)full and I must remove by hand a large temporary file from /data/system.
Well, /data is used instead of /cache, 100mb wasted in this way.
Someone else finds experiences the same behaviour?
I was thinking about a linking trick to use that space (for dalvick or swap...), but I'd prefer it would be correctly used by system.
Infos: SK17i, stock .587, root, locked BL, link2sd.
Thanks, bye.
Same in Xperia Mini
Well, this isn't nice...
some ideas
Hello! I was doing several searches and come to some results:
Note: I will not try it on my phone (Xperia Mini Pro) because I'm still an apprentice to flash and modify it, and secondly I have no resources to change my phone if something goes wrong. Finally, sorry for the grammatical errors, I do not speak English natively.
The following are links taken from different forums / blogs (neither is my property).
The general idea is the same, use parted (or any similar app) to edit the partitions inside the phone.
One of the problems that arise and I have doubts about is, what is the file system of internal partitions? ext3?. is something that I have to keep reading.
This is the first blog I found where it gives a possible procedure to follow:
http://aarondiep.blogspot.com.ar/2011/11/resize-partition-on-android.html
Here's a post where one of the users that modify his partitions and, later, returned to stock status.
http://www.droidforums.net/forum/htc-droid-eris/78650-internal-storage-partitions-screwed-up.html
Here is a guide on how you use parted (includes screenshots) BUT IT DOES WITH THE SD CARD
http://mobilecon.info/how-to-partition-sdcard-using-parted-partition.html
Finally, a tool for YAFFS2 file system:
http://forum.xda-developers.com/showthread.php?t=1645412
I hope these links are useful. I really would like to use optimally all the hardware of the phone.
Exitos!! :laugh:
Hi!
Thanks for your interest!
Resizing partitions, I read time ago, is a really critical operation.
I expect to have /cache partition as it has been made, the problem is that apps do not use it!
Resizing that block device to, let's say, zero, would give space to other partitions, but we'd lack a cache.
I definitely believe one of master questions is: where the hell does playstore download packages before installing?
During a big upgrade (let's say angry birds Rio 30+ megs) with df I only see /data growing (and /cache always empty), but after a lot of searching for newest and biggest files (busybox ls -ltrh, busybox ls -Shl) I could not find where they are put.
Once found this download location (no, it's not /data/data/com.android.vending/cache/main), would be easy to bind /cache to this dir.
Apk files from Google Play is downloaded to: data/data/com.android.providers.downloads/cache/
Wysyłane z mojego SK17i za pomocą Tapatalk 2
Hi
Many thanks for this tip!
Well, it's true apk are downloaded there.
BUT I see a strange behaviour: when I recieve the "low memory" (space on /data partition) notification, the apk suddenly disappears! :what:
In logs I see a lot of "couldn't openat chache: no such file or directory" immediately before low space notification log line...
You can use cache as swap if your kernel support it..
Sent from my Walkie'Talkie
Hi
Well, i symlinked /data/data/com.android.providers.downloads/cache to /cache/cache, and the partition is now correctly used by play store.
Is really strange that this is not a system default, btw.
EDIT: the /cache/cache was regularly erased by system, I symlinked /data/data/com.android.providers.downloads/cache to /cache and all is ok now.
EDIT2: you must previously remove (rmdir) the existing /data/data/com.android.providers.downloads/cache!
Could you put the exact command?

How do i mount internal memory and pull out my data? Any help is appreciated. Thanks
It's a CM LInaro Kitkat 4.4.2 with custom kernel. With older versions of Android I was able to do what I was attempting to do but I've read somewhere about certain change when mounting storage on 4.4.2.
Thanks in advance.
Noone? Reallu? At least some info about device reading out data directly from the storage chip?

That isn't even remotely possible for an end user. The only people who might be able to do that is a company which specialises in recovery of data from dead HDDs'. If it is possible, expect it to be very very expensive. I've never seen a single person post here in 2.5 yrs saying they've had this done successfully. Even if this is was possible, fixing your screen would be cheaper.
Very few people here have attempted to do what you're doing with ADB (me included; frankly, if the data was that important to me, I'd pay $120 for a new screen to save myself hassles, but I wouldn't be in that situation to begin with because I back stuff up). Unfortunately, you're going to be in for a rather long wait if you don't manage to work this out on your own, many people who may have been able to help you don't post here anymore, they've moved onto other phones given it's been 3 yrs since this phone was released.

Well at least I gave it a shot but yeah... you are probably right I shouldn't have bothered posting and I was pretty sure someone somewhere might have asked the exact same question unfortunately I couldn't find it. I know how annoying these questions can be and I'm very sorry if I made someone angry. Long story short - I managed to get my pictures and videos back, as well as contacts. I do back those stuff up. however I had some .bin files for work that I lost but I've been living with that. It just might take some time browsing on the Internet finding them again but I'd rather do that than trying to do anything with the phone. I bought it $100 last year, the screen alone is that much, there's no point in fixing it. And at last but not least, thanksfor the reply.
Nah, they're not annoying It's just a very unusual situation, and as I said, if you want help with that sort of stuff with this phone on here, because so many people have moved on, you need to be really patient, that's all.
Same story
Shortly broken display no touch input. I had custom KitKat rom.
I had almost given up trying to mount the internal sd card with ADB, following numerios forum post instructions
here is my solution using windows pc and ADB
I rebooted in recovery (I think it was 6,0xx)
Using command prompt (you also need adb.exe) :
adb remount
adb root
adb usb
Those 3 command somehow mounted the internal storage and I was able to use the "adb pull" comand to copy the whole internal sd card to my hard drive
After that I went with "adb shell" to check how the sd card was mounted and here is what I found:
"

Hi All,
I have purchased a leagoo lead 1 http://www.leagoo.cc/c51181.html (slick design and under 150$) but now I'm trying to get it rooted.
I've tries Kingo root, V Root, Shuame, Towel root, Framaroot and none of it is working.
The phone operates on 4.4.2 with an MTK 6582 processor..
When holding Vol up + power I get a fastboot option though.
Would extracting boot.img and rework it mean something? or has anyone usefull tips?
Thnks in advance.

First of all .. I managed to root it.
Needed: Kingosoft Sony bootloader unlocker, Kingosoft one click root, (www.kingoapp.com) Mobile uncle tools
Start sony bootloader unlocker and run it with your phone connected.
It will restart your phone to fastboot and then it remains idle.
Keep your phone plugged in, switch it off and boot manually into the fastboot (power + vol up)
From here the unlocker will proceed unlocking.
Step 1 done.
Now open kingosoft root connect the phone and let it do its thing.
At restart of the phone kingosoft will show on screen a message like "checking root status"
Launch mtk uncle and enter engineer mode.
Go to log and debugging tab ans select user2root
Select Root.
Now kingosoft will tell you that root is succesfull and restarts the phone.
That's that. Phone is rooted. For recovery see the posts 22 and 24 from Vampirefo who did the real hard work in creating 2 flavours of recovery. [emoji106][emoji106]
Non linux users can also flash the img through MTK uncle from sdcard if that doesn't work. See post 40 for flashing recovery via SP tools
The phone runs smooth on what seems to be Yun Os aka Aliyun. Gapps and all android functionalities are working well. At first it seemed that the WIFI reception was poor but with an OTA update seems this has been fixed.
Only trouble I have is getting a GPS fix. It does see 11-13 sattelites but I'm unable to get a proper fix on it. Also the EPO function is not acessible from 4.4.2 . so now with root I'm trying to inject the GPS.CONF file into system/etc and see if it gets a fix or not.
For the time I've been playing around with it... it seems a pretty decent phone with a good response for a reasonable price.

I Downloaded from kingosoft the sony bootloader unlocker.
It puts the phone in fastboot mode and then it hangs. I unplugged my phone, switch it off (keep the unlocker running) and manually booted into fastboot (vol up+power) the bootloader unlocker then proceeded untill finished.
Next I installed this root tool and started it while the phone was still in the fastboot mode. after a couple of restarts it says checking for Root, then I decided to start MTK uncle tools and scroll to "log and debugging" and select User2Root. then clicked Root and all of a sudden the phone was sucessfully rooted.. Smiling Smiling I don't know what exactly sparked the root access but It's rooted and works!
If anyone can reproduce this in a correct order. please feel free to share.

Mine wasn't but probably due to a factory reset from recovery? OR it wasn't fit yet to see the dutch sky
Managed to root the thing?
Yes mine is rooted also, Similar to the way you rooted yours.
I used Linux and wine to run the bootloader tool from there, I had to use another tool to get temp root, then I pushed su and set permissions.
The bootloader tool you used works via wine but the root tool doesn't.
Sent from my Leagoo Lead1 via taptak.
So we can carefully state that the (accidental) rooting method works.
Btw. I figured out that /system is ro and not rw
Also with adbd insecure it remains ro. Means it has to be scripted to rw at every boot or.... Can try to run framaroot exploit.
System is supposed to be ro this is normal, to get rw add busybox and then remount rw.
Also you can edit the boot.img and make a insecure boot.img and flash, I have done this myself, this enables adb remount, you can add a script to /system/xbin, to force rw or ro.
I wouldn't want rw all this time, as this can cause instability use ro until you need rw, es filemanger with root also allows you to mount system rw as needed.
Added some pics of phone showing it's rooted.

No ideal what you are saying, Have you rooted your leagoo lead1? if so by what? what is VOcano? Post more details, you say you root but not done, what does that mean?
Hacking through the recovery is a bit out of my league.
Is there a tut how to do this on a windows machine?
Another way I could think of is to create an ext2 partition (with an external program) on the SD card and use link2SD to utilize that as internal memory.
But I'm open for smarter ways of doing so.

There isn't a tut for Linux, so I doubt there is one for Windows, hacking comes from one's mind, lol. If link2SD works for you that would be just fine.
My method requires pulling stock recovery from phone unpacking recovery, adding adb support adding busybox support repacking stock recovery then flash to phone.
From the repacked recovery, full access to phone is possible, dual booting, running from phone from sdcard, creating and restoring backups.

Things just got worse hehe.. Did the whole link2sd thing and linked a couple of apps and voila. playstore, facebook, whatsapp gone.. and nowhere to be found back........... doubting whether a factory reset would fix the thing? So in short.... nope.. link2SD does not work.
wouldn't posting the repacked recovery and flashing it to another phone be possible?
Yes the recovery can be flashed on another rooted tablet, but there is more to getting data on sdcard that just flashing a recovery.
I just now modified cwm recovery to work on leagoo lead1, cwm recovery is bigger than my packed stock recovery, but I am able to squeeze in it, lol.
In Utopia..... This would be a good solution for the Leagoo too

Hey guys,
unfortunately i think i bricked my prime
Today i flashed crombi-kk rom which worked flawlessly fine. I came from HairyBean 2.31 so all i did was to up update my TWRP via fastboot and then flash the rom. As said, that worked fine. After my first boot of the rom i thought that i would like to test the "F2FS" option. For this i updated TWRP to v2.8 via the zip-file from this thread: http://forum.xda-developers.com/showthread.php?t=2772093 . This also worked and i've got my TWRP to the new version.
Now i wanted to format the /data partition to F2FS so i went to
Wipe>>Advanced Wipe>>Choose Data>>Repair or Change File System>>Change File System>>F2FS
At this time it told me that it can't UNmount the partition and therefore it couldn't change the file-system.
Dumb as i am i thought: "Okay, then why don't just unmount the partition" so i did this (Mount>>Disabled "Data") an then retried to format the data partition with f2fs. During this process i have to assume that something went wrong? It gave me some error which i fool can't remember.
From this point i couldn't access the /data partition anymore, i can't mount it nor can i boot into Android.
I still have access to TWRP and can get to fastboot access. I have no ADB Access in TWRP - it just can't recognize the prime. In Windows-Hardware Manager it just says: Transformer?! (i have universal naked driver installed)
Forget the last sentence - it seems that my USB-Cable is partly broken. Sometimes it recognizes the prime and sometimes not!
Is it gone forever or is there still hope to recover it?
Hopefully someone can help me, i'm really desperate
P.S.: D didn't want to make things worse, so i stopped messing around with it - would it help to reflash the ne0zone75_tf300t.blob file? Is this even possible if i already updated the TWRP to a newer version?

As long as this is the fact, we don' t call it 'bricked'.
Try following one after another:
1. TWRP>>Wipe>>Advanced>>[check / data]>>repair file system, flash ROM again.
2. Fastboot:
Code:
fastboot -i 0x0b05 erase userdata
- then flash ROM again.
3. Last ressort: Flash stock ROM and start from scratch.
... hope you've pulled your nvflash files. Good luck!
... you might also want to flash another TWRP, though ne0zone75's normally works well. Try the official 2.8.3.0 (for tf300t because you are on Hairy Bean), works good with my prime.
Thanks a lot for your reply
I've tried the steps you provided:
1) While repairing the data partition it said again that it can't mount the data partition. (Picture of it in the attachment)
2) Reflasing the rom worked okay but as expected it couldn't boot (stuck in bootscreen) - in TWRP the /data partiton was again unmountable
3) erasing the userdata via fastboot gave me the following:
Code:
erasing 'userdata'...
FAILED (command write failed (Invalid argument))
finished. total time: 0.002s
At this time i didn't tried to reflash the rom because i don't think it would change anything?!
4) i only have the old nvflash files from ages ago when i started flashing with androwook - i fear they are the wrong ones? I don't have any clue what to do with these - are there good instructions to get the tab back to it's factory state?
Last but not least - do you have a link for the right TWRP you're talking about. I don't want to gave the wrong one a try

Sounds as if partition table is faulty.
1. You could try to redo the Hairy Bean procedure.
2. If you feel lucky, then you could try to format partition manually using
Code:
mkfs.ext4 /dev/block/mmcblk0p8
4) i only have the old nvflash files from ages ago when i started flashing with androwook - i fear they are the wrong ones?

nvflash files don't grow sour; you could try without changing to wheelie your blob.bin. If it works, you are safe and can continue with the other blobs.

Okay, now i know why they always say that flashing is nothing for noobs
I'm a little bit confused - what (in your opinion) is the best shot i should give a try?
Formatting manually (from where? In TWRP or via adb? I'm on Windows)
Reflash everything with NVFLASH (is that possible without any hassle - the NVFLASH files are from ICS-times and i'm on JB/KK?!)
I know it's annoying to help someone who doesn't know what he's doing - hope you have time to get me through this flashing nightmare :/

I would first do that manually from TWRP>>Advanced>>Terminal Command>>Select Folder (root)>>type in: mkfs.ext4 /dev/block/mmcblk0p8

Important is, that blob.bin works with
Code:
wheelie.exe -r --blob blob.bin
After that you should flash 'bricksafeTF201.img' and 'unlock-token-TF201'. Then you can flash any blobs of unblobbed ROMs you can find in the internet or flash stock ROM (JB). Then proceed to fastboot custom recovery and zipflash custom ROM.

Hooray! :victory: Thanks a lot - everything is back where it belongs
Just for the learning effect - do you have any idea what did go wrong in my case and how would i correctly change the format of the data partition to f2fs? I think i've read a lot of times that this would improve rom speeds a lot?!

Congrats!
If you would care to tell what you did last, one could make a guess, what went wrong.
... and yes, changing /data (only!) to f2fs makes a tremendous difference in speed. Normally TWRP complies the job without probs. What TWRP do you have now?
I prefer @ne0zone75's which I linked some posts before. They work on all my tabs.
I have installed v2.8.3.0 from the site you gave me above
Mh, as said in the first post i did the following steps to change the format
I tried Wipe>>Advanced Wipe>>Checked "Data">>Repair or Change File System>>Change File System>>Choose F2FS
Then the system gave me an error that it couldn't access the partition because it was mounted or couldn't be unmounted or something like this
So i went back to Mount>>unchecked "Data"
And then again to Advanced Wipe>>...>>Change File System>>F2FS
After that something went wrong because after that step i couldn't mount the data partition anymore?!

Yes, but what did you to fix it then?
Oh sorry, now i get it
I just used your command for repartitioning(?!?): make_ext4fs /dev/block/mmcblk0p8
I am still of two minds of f2fs on these tablets.. Just gone back to ext4 to compare... As was getting to sticky on the F2fs with redraws and lag..
Anyway good to hear a successful conclusion on the come back by the OP

Good! Glad, it helped you. Now you could try the 'mkfs.f2fs' command also.
Already tried that - this time it worked without problems :highfive:
Thanks again for the great help!! F2FS brings the prime to a whole new level, now i just have to figure out how to change the dock layout language

That should be no problem. If you click in dock, there should be a keyboard icon in notification area, clicking it settings dialog will appear. Additional in settings>>language and input>>physical keyboard you can set keyboard layout of dock.

Disk /dev/block/mmcblk0p8 doesn't contain a valid partition table
[email protected]:/ #
Disk /dev/block/mmcblk0p8 doesn't contain a valid partition table
this is what I am looking at as a problem maybe?
is there a terminal command to see all the partitions and sizes?
I might have to take this thing back to scratch and start again as been flashing left right and center on it of late.

No that's normal for f2fs, only fat systems have readable PT. What I was interested was geometry of fs and that is the same as mine. So everything is o.k. You have your tab up and running - that counts.
There is a free app Storage Partitions in the store, which can do no more than show information about partitions. Mainly an exploit of commands
Code:
cat /proc/mounts
and
Code:
cat /proc/partitions

Used that one and another to have a look..
This is what I get, just for the hell of it..
As said for me.. F2Fs on this one doesn't play nice and the last few days I am back to Ext4..
Running it in and let it settled, putting it through its paces with plenty of tabs in chrome open and multitasking back and forwards in to Tapatalk and it runs normal with out lag and redraws..
I am using apex as a launcher and under F2Fs with kept in memory set..it was redrawing to the max and timing out from coming out of sleep..
Playing with other tweaks to see if can get it to a sweet spot.
Will let it settle for a few days and play then swop back and see which is better with the tweaks added
Okay so here it goes. I had missing IMEI problem in a custom ROM when not on a samsung base. I had a neatefs (app on android) backup which I tried to restore using HC ktool (Bad idea, I know). It gives me a successfully done message and tells me to reboot. Now my phone is stuck in bootloop no matter what (Stock firmware, wipe data, factory reset nothing works) and the recovery gives the error mentioned in the title.
/efs is unmountable for me. I tried various methods mentioned for S3 and Note such as connecting the phone in ADB mode and following the steps but none of that works.
Have you tried formatting /system, /boot, /preload /storage/sdcard0 ? From a rooted kernel, of course.
And then trying reflashing the original stock rom.
hope this helps http://forum.xda-developers.com/galaxy-s3/general/how-to-fix-efailed-to-mount-efs-invalid-t2858056

I have tried formatting /system and I don't think that formatting /sdcard0 is going to help, it will just increase the burdon of data transfer. As for others, I was afraid it will make more mess than solve any. Are you sure formatting those will not affect anything?

I've tried all that, none helps. I've even installed a busybox as mentioned somewhere else which said that the syntax mke2fs is not available without a busybox. Nothing worked. Still unable to mount efs afterwards.

I'm pretty sure it won't damage anything, or at least to me didn't. Because whenever I want to reinstall a new ROM I always format everything I've mentioned earlier so I don't find it harmful for the device, as long as you don't have data worth backing up.
Also, wipe dalvik.
If you installed busybox, make sure you uninstall the previous version prin pressing uninstall, and them installing 1.23.1 because for me sometimes it says it's intalled, but after reboot I still have the old one.
After you do that, connect phone to PC and try running
adb shell
Once you do that, give a try to the command
umount -f /efs
even if it says it's umounted, then type
mount /dev/block/mmcblk0p3 /efs
mke2fs /dev/block/mmcblk0p3
mount -w -t ext4 /dev/block/mmcblk0p3
Click to expand...

These two are the commands everyone is talking about the S3 phone having same issue. I tried everything. The first command works and it shows something like:
"The filesystem will be automatically checked every 35 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override."
For the second line of code when I try, this is what I get:
"It says "mount: can´t find /dev/block/mmcblk0p3 in /etc/fstab"
Now I have also tried adding space and /efs to the second command. It gives me nothing, not even any error. So I presume it works but then when I reboot efs is still messed up. I have no idea what these commands does actually. I think it has something related to re partitioning. Shouldn't the second command line give the same output as the first one? Its been a whole day searching for this thing. I got my phone messed up real bad.
EDIT: One more thing, when I hit the # df command on ADB, it shows 3 drives (/dev, /cache, /emmc) when not in su and 4 when in su (/dev, /cache, /emmc, /system). No where it shows any efs partition. Is there suppose to be any?
EDIT2: After the second line command. Using mount -t following someone's guide I get the efs partition but I think it is way too small. See the attachment. This partition is gone again after reboot.
OH GOD I got it working. After more searching, I found out the the block used for efs storage in S2 is mmcblk0p1 not mmcblk0p3. Phew!
Follow the same commands to make it work. Just rename the block.
Here is a guide which helped me figure out the block: http://www.usoftsmartphone.com/t306464.html
Thanks everyone
im having same trouble now with the S7. the page you share not there anymore. please share me how to figure out the block
