Almost bricked my phone

I wanted to update from Android 2.3.5 to 4. I rooted my phone properly, and that went fine with Superuser elite. Because of upgrading, I installed CWM 5.0.2.7 via Odin. In the background CWM shows errors:
Code:
Cannot mount /cache!
And errors like that. I formatted microSD card, inserted it back, formatted it. The errors are still here. Because of the left cache folder, I couldn't install Android 4. I followed all guides on Internet, the problem is still here. I thought newer version of CWM will solve it, and I downloaded version 6 and flashed it through Odin(WHY?:crying. Now I cannot go to download mode or CWM, I am stuck at SAMSUNG logo when I boot the phone. Any help will be very appreciated. :highfive: The last thing I would do is to go to shop and request a new one, because my warranty expired in February. It's cost is 210 euro. This is the second time I almost bricked my device.

I'm trying this.

EDIT: ADB cannot see my device! I also tried Heimdall, but with no luck. This means I am screwed? Hope not!!

cwm doesn't support RFS . so you should format cache and data partition before installing custom ROMs.
goto recovery and do this:
wipe data/reset
advanced-> wipe dalvik cache
install zip from sdcard -> choose ROM file
wipe data/reset
advanced-> wipe dalvik cache
reboot

But, the real problem is: I cannot go to CWM or download mode! Also, I cannot format cache via CWM because of the errors in first post.

when you connect usb jig to your phone an alternative download mode start and you can flash a stock rom via odin!

OK. I though to do it this way:
1. Buy USB jig.
2. Go to download mode.
3. Flash TWRP with Odin.
4. Install Android 2.3.6.
5. Flash CWM via Odin.
6. Fix cache problem somehow.
7. Install Android 4! Yay!
For the step 6, how can I fix the cache error?

NOOOO! you should install TWRP with custom recovery, NOT Odin! don't do same mistake again.
this is the proccess:
1- buy usb jig and connect it to your phone.
2- flash Stock Firmware(it must be 2.3.x) with odin! (you can download stock firmwares from samfirmware.com)
3- flash this with odin:
http://forum.xda-developers.com/showthread.php?t=1339640
it's most stable recovery that we have!
4-wipe data/reset
advanced-> wipe dalvik cache
5-install zip from sdcard -> choose ROM file
6-wipe data/reset
advanced-> wipe dalvik cache
7-reboot
and now you have android 4! yeah
Stock Roms have RFS partition type and our custom recovery doesn't support RFS so that mount problem appears. but you can format partitions again and convert partition to Ext4. just do step 4 .

CWM can convert to ext4? I thought that only TWRP can do that.

yes it can.it's like formating your Usb pen drive . just go to cwm5 and wipe data/reset and wipe dalvik cache and install android 4 zip file.

yes it should work. it's just a simple resistor. you can make your own jig:

i heard that samsung changed bootloader so you can't reset number of flashes any more. you said your warranty expired in February! so why do you want to do that??

Thanks. I will buy one as soon as possible. For the bootloader, I am just curios. Thank you for great answers!

I solved it this way. I went to service and they somehow installed Android 2.3.6. Now I partitioned my 8 GB SD card via CWM and currently I am trying PAC-man ROM(S) from this forum. I will post what will happen.

Still no luck.

[GTab 2 7.0] Can't install custom 4.4.4 ROMs

I can't install custom ROMs on p3113
Steps Taken
Starting with stock firmware/recovery
using chainfire autoroot
reboot
use root checker to confirm root
Use Odin to flash a custom recovery. (I tried Andi's CWM, TWRP, and also Philz touch 6.40)
Custom recovery flashes no issues and I can boot into custom recovery
I do factory wipe, then also dalvik, and cache again for good measure
Go to install a custom ROM via recovery
Go to reboot and the recovery prompts me that I need root and to asks gives me an option to install su
When I do that and reboot it bootloops.
I've tried 3 different recoveries. The ROMs I've attempted to flash are Dhollmen 4..4.4, and Andi's Omnirom 4.4..4.
It appears I can install 5.x ROMs without issue.
Any idea what I can do to fix this problem?
edit: in the process of trying twrp 2.8.0.5
edit2: no luck with 2..8.0.5 which I found on Dhollmen's thread. Going go browse through the forum looking for older recoveries.

Have you tried clearing /system

Yes

Try updating your SU binary before the flash, also try plain jane CWM, Andis CWM acts weird sometimes.
If SU binary won't update delete and install a different one, then update.
Pp.

Wipe cache
Wipe dalvic
Format /data
Format /system
Reboot recovery once
Flash rom.zip (don't flash anything else!)
Reboot into system, don't use "fix root"!
If it boots (Lollipop takes some time) your are good to go to flash gapps etc.

The only thing I wasn't doing was rebooting after wiping. Wiping then rebooting let me install the 4.4.4 ROMs no problem. I never would have figured this out thanks a lot. What causes the need to reboot after wiping?

@HappyRoot good to hear.
Seems like one of the partition wasn't unmount by the updater-script or recovery after wipe and caused that issue.

It only worked with installing SlimKat/Dhollmen I'm still unable to install Omni 4.4.4. I've done a complete wipe Odin'd twrp 2.8.4.1 and flash the zip via adb sideload. I keep getting an updater binary error.
update: twrp would crash at 37% and give me a binary error. when i odin'd updated cwm from you android file list i was able to get to 100% but then i would get a status 6 error.

Then you are doing something wrong...

Stuck in Recovery twrp (can't wipe or install ROM)

First things first, I'm a newbie when it comes to all these.
I installed CM11 after much effort, but some things didn't work out well so afterwards, I installed CM12.1* (FXP-cm-11-20150301-UNOFFICIAL-taoshan).* But then I decided that I wanted to change my Gapps Package, so I went to recovery mode once again to wipe my phone and install CM12 all over again.
The thing is that for some reason I just couldn't wipe it (no error message) but I was able to log in back to the system (CM12).
I messed around with a few settings and finally I decided to install twrp 2.8.7.0 through the flashify app. I rebooted to recovery, tried to wipe again my phone and then, all hell broke loose.
I realized that I cannot wipe internal memory of all things, and cannot install any new ROM. Can't flash another recovery either through windows flashtool like CWM 6.0 Philz touch, for example. Well, it does flash but my phone keeps on logging into the twrp recovery. I also can't flash my original fft (obviously). I can't do really anything besides messing around with twrp options (and I've messed a lot with them). I'm all out of ideas, so please someone help. When trying to wipe internal storage, the following message appears:
E:mkdosfs /dev/block/mmcblk0p32 process ended with ERROR=1
E:Unable to wipe '/sdcard'.
E:Unknown MTP message type: 1
E:Unable to wipe '/sdcard'
I have the whole log, for anyone interested.
Please help and remember, I'm a newbie.
Thank you.

Thank you for your answer my friend, but I actually managed to fix my problem just moments before you posted your answer! What I did was to flash the cm12.1 recovery nightly which logged me into this recovery (although it seemed all messed up and.. broken). Nevertheless, I managed to flash the CM12.1 ROM from there and everything worked fine!

Bro #immortalwind.. I'm having the same problem exactly what you had. Seriously fu***d up with all with boot loop @ recovery. Could not able to hard reset / factory reset at neither CWM nor TWRP. Tried all knows possible ways. Please could you help me here. Any1 who can halp me here pls...
P.S: literally not moving from the boot load, so flashing a ROM could not be possible i think. any other suggestions please.....

Just reflash stock ftf. You'll be good to go. If that fails, check drivers and downgrade flashtool. After that, normally, install a boot image with a recovery, install your rom gapps, reboot.

Managed to flash.ftf... Thanks for the help friends.

I have a custom rom downloaded. But to flash it, I need to erase everything. That I am unable to do because the recovery dosent wipe data. It led to a bootloop. I got back the stock firmware and tried again and same result. Further more, I cant even factory reset. I'm using TWRP 3.0. Someone please help!

Ive tried that 4 times till now. It has been in a bootloop thrice. And I flashed stock. I currently am using stock firmware but want to flash the custom rom. The recovery is failing to wipe data because it is failing to mount data.

Try this
1. Reboot to recovery (TWRP)
2. Select wipe.
3. Select advanced wipe.
4. Check system.
5. Repair or change file system.
6. Select change file system.
7. Select format type.
8. Swipe to change.
9. Select repair.

there is one problem with stock rom. its encrypts the data partition right after installing stock rom, therefore twrp can't access data partition. i had similar problem earlier. this is how i managed to fix.
solution: http://forum.xda-developers.com/showpost.php?p=67980158&postcount=7
i suggest you to stick with stock rom, because right now whatever roms or recoveries are made for this phone are blindly ported (just copy paste roms). i have tried about 3-4 roms for this phone, all had major bugs especially battery related. there is only one developer who made a stable rom so far is beingtejas, search his thread. if you really want to use a custom rom, try THIS rom made by gaurav kesarwani with help of beingtejas that is why i am suggesting it you otherwise it didn't worked for me atleast.

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 .
