[Q] E:Unable to mount /system [SULTAN] - ONE Q&A, Help & Troubleshooting

Hi guys.
I wiped data, cache, delvik.
I flashed latest stable CM
I flashed Gapps Pico
I booted once
I rebooted into recovery TWRP 2.8.6.0
I then wiped date, cache, delvik again.
I then tried to install SULTAN 5.1.1 ROM
Getting E:Unable to mount /System
Why is this?
Stuck on this screen, waiting for any reply
Thank you!

I think you have to wipe /system too before you flash ROM.
Here are his instructions:
Next, download and flash the latest official CM12.1 snapshot. Then, without rebooting from recovery, wipe /system and flash my ROM. This process is necessary to update various firmwares (including TrustZone), as the updated firmware is needed by my ROM. After flashing my ROM, flash a Google apps package, and then reboot.

Help me save my TF101

Well I dont think I totally screwed it up because I am able to get to the recovery but here is the scoop.
I decided I was going to root and install jellybean. So I used the 1 click method to root from [TOOL]"1-Click Transformer Root"-Root/Unroot/cwm/stock rec-TF101(G)/201/300T(G)/SL101 - xda-developers
I did the 1.1 verison. All went well tablet was rooted my stock rom still worked fine.
Then I went to flash jellybean rom which i did this one here v6.0 [ROM][JB][4.1.1] AOSP build #6.0.0 - xda-developers
Before i flashed i made a nand back up. and wiped all cache.
After install of RaymanFX's jellybean rom it got stuck after the splash animation.
I then tried to reflash it. Only to see the same result.
So I cleared all the cache again and ran the nand backup i made now i am stuck at asus splash screen.
Someone please tell me what i am missing.
Thank you in advance for any help.
Copy this ROM to your SDcard or MicroSD card, whichever one you used to hold the ROM the first time

Wipe and format SD card, cache and dalvik, make sure you are flashing the correct ROM for your phone, wipe dalvik and cache between any additional flash, like gapps, kernel.. Ect.. And you should be good

Try
WIPE Cache + WIPE Dalvik + FULL WIPE(WIPE DATA + FORMAT /system + FORMAT /boot)
Then INSTALL the ROM
Then INSTALL the GAPPS
Then WIPE Cache + WIPE Dalvik
Goodluck!

[Q] CM11 - cannot get past the boot screen

Hi,
First, I followed the instructions in this guide: http://forum.xda-developers.com/showthread.php?t=2507905
I installed the CWM recovery and then flashed the CM11-20131228 nightly and then the recommended Google Apps that are linked at their wiki: http://wiki.cyanogenmod.org/w/Gapps#Downloads (I took the 20131208 ones)
Now my phone is stuck in the boot screen with the circle spinning around the cyanogenmod logo (I can boot the bootloader and recovery but when I try to boot CM11 it’s stuck) and I dont know how to get to a working cm11 rom. The guide said that the first boot with a new rom takes longer than usual because the phone rebuilds caches and so on but I think it should not take more than half an hour...
What I already tried is:
- Wiping the chaches with the CWM recovery an then booting cm11 -> still just the arrow spinning around the logo
- Wiping the caches with recovery and then re-flashing the same zip without flashing the google apps afterwards -> did not work
- Wiping and then pushing the newer cm11 nightly via adb so that I could try this one -> recovery did not find the pushed zip on my scdard
- Wiping, then tried to install the new nightly via adb sideload -> cmd prompt said it was send properly and as far as I can say the phone installed it but I was still stuck on that bootscreen ...
- I even restored to the stock 4.4.2 factory image and then flashed the cwm recovery, than wiped caches and then installed the latest cm11 nightly an then the google apps but I still can not get past the boot animation
What am I doing wrong and how can I get past the boot screen?
You talk about wiping caches but are you wiping data too?
Oh, yes. I just didnt mention it. I always did the three steps from the guide:
wipe data/factory reset
wipe cache partition
advanced > wipe dalvik cache

So you get the bootloop only when trying to install CM and when you flashed the factory image, it booted up fine?

Exactly.
I install the factory image with method 1 from this guide: http://forum.xda-developers.com/showthread.php?t=2513701 and then flash CWM recovery to install CM (factory reset + wipe cache + wipe dalvik cache + install cm-zip + install gapps-zip) and then there is the bootloop.

Sometimes formatting all of the partitions (except the sd card) works.

I got another problem now ... The last thing I did was flashing the stock rom. Now I want to flash the latest CM nightly (20131229) but fastboot does not let me install cwm recovery and says
Code:
FAILED <remote: partition table doesn't exist>
I flashed the whole stock rom again but the error still occurs... I have to wipe the partitions after I installed CM, right?

Are you using
fastboot flash recovery recovery.img
Where recovery.img is the cwm image file

I use this command. But I missed a c in recovery so fastboot did not find the partition named "reovery" >_< Ok, CWM is installed. Now I have to install CM11 an then wipe the 4 partitions you mentioned with cwm? Wheres the option to wipe system, I just find the other 3.

So I installed CM + Gapps and then wiped data, cache and dalvik cache with CWM. Now Im waiting for 8 minutes for the bootscreen to go away, but think it didnt work. By the way, if I wipe the system partition, I delete CM, dont I? I dont understand how that will help booting into CM.

Wipe before the install.
So,
1 Put rom zip on phone internal storage
2 Wipe partitions except internal storage
3 Flash rom
4 Flash GApps
5 Reboot

8 minutes is too long. You have some other problem. Do any other roms work? Wiping system in twrp does not wipe the internal sd card. That's why you didn't find it in cwm.

I will try the AOKP nightly and post the results. Is it okay to just wipe data, cache and dalvik cache before installing the aokp zip or is it better to flash the stock rom before flashing aokp?
No need to flash stock, just do the wipes

If you are using CWM6 there is known bug that causes this. Just revert to CWM5.
If not just wipe everything (EXECPT SDCARD) and flash again
If that is no go then flash stock rom via odin, flash CWM5 and then flash custom rom.

Hi people :laugh:,
I have a Xperia J (st26a) and I tried several times install the CM10 (FXP240, FXP220 and the lasted build) and everytime a bug appears in wifi.

Someone, please, can give a light for a noob who wants to use the CM10 on your jlo?
My english is very poor.
Hi Daigou, this is the last and final CM10 bulid by FreeXperiaProject (FXP250) (http://d06.unr.li/dl/13791c8c0a81d/cm-10-20131224-FXP-jlo.zip)
try this way:
1. Flash ICS firmware
2. flash CM10 kernel
3. Wipe Data and cache
4. Go to mount and storage -> mount system
5. Install CM10
6. Reboot
7. Go back to CWM again, and mount system again
8. Install Gapps
9. Reboot
