Hi,
I have Yotaphone 2 that turn on and off every 5 minutes,
When its bootloop I see Powered by Android
I also did in fastboot this command:
fastboot boot twrp.img
and it works! But what i need to do from here?
I just want the phone to work normally
Thanks!
If phone has a microSD card slot - what IDK - use an external sdcard reader/writer or another phone that has a microSD card slot and transfer phone's Stock ROM ZI-file from your computer to the root of the mictoSD card, then insert the sdcard back into the bootlooping phone.
Flash this Stock ROM via TWRP.

Hello all
i updated to the 3.24 firmware, and since then i only get untill the splash screen then it restarts again!
what can i do now? i can't restore the old firmware because each time i go to recovery it asks if i want to update firmware (because the new firmware file is still in sd card).
any ideas?
best regards!
Remove the firmware from your SD card and pull out the battery. When you delete the PG58IMG from you SD card, put in back in your phone and also your battery.
Then you turn on the phone into recovery mode and install the rom.

just open back take out sdcard, boot into recovery and put sdcard back in then mount usb from recovery and delete it then put new ARHD or Insertcoin and flash!

^^This^^ or use adb tools and type 'adb reboot recovery', use your recovery to mount your sd card, and delete pg58img.zip file from your computer. Have to get the command in right when your computer detects your phone.
thanks for the quick reply

can you get into bootloader? if you can then go into recovery from bootloader
Or you could take out the sd card, boot up, and then put the card back in and then remove the file. I had to do that the first time I flashed because I didn't have a micro SD adapter with me
So...kinda hoping I'm not totally hosed here. I'm an idiot and wiped my ROM and stuff to the point I can't copy a ROM over to my tablet.
I can get to TWRP, but TWRP will not mount an SD card (using my keyboard dock of course). Fastboot does recognize my device, but without a ROM copied to the internal storage I don't think I can flash it at all.
From the boot menu if I select the USB fastboot mode my computer will see the TF and install drivers, fastboot sees it, adb does not. It's not listed in my 'computer' under windows.
Hopefully that makes sense.
You can do one of the following:
... use adb while in TWRP and copy the ROM via adb push.
... put the ROM on a microSD card and use that in TWRP.
... use fastboot and flash the ROM's blob via your computer.
Except ADB won't work, just fastboot oddly.
Edit - I'm going to see if it'll recognize a micro SD, it's possible the SD slot in the keyboard dock isn't supported by TWRP.

TWRP only detects micro SDcard on the tablet, NOT the SDcard in the dock. So the easiest solution is copy the file to your MICROsdcard, then turn off your device, insert the microsdcard, then boot up into twrp, you should able to see the file on the micro sdcard.

Hi guys,
wanted to root my TF300, i reached to the stop where i have CWM- based recovery v6.0.2.3. but aterwards when i wasnt to flash with root-signed.zip to root. i get error, cant mount sdcard. there are bunch of errors like cant mount /casche
any help?
For those that have updated to 4.2.1 (bootloader) and are now unable to mount: cache, data, external sd card etc.. in recovery.
TWRP (2.4.4.0 or below) & CWM (all) will not be able to mount these partitions. You need the modified TWRP for 4.2.1
Code:
fastboot -i 0x0b05 flash recovery twrp421.blob
download link can be found here
Cards that may not work on modified TWRP for 4.2.1
sandisk 64gb micro SDXC class 10 (not sure if this is size, type or class issue)
Working cards
sandisk 8gb micro SDHC class 4
sandisk 16gb micro SDHC class 4
What if you cannot flash another recovery because the system when restarting loops and eventually enters CWM?
My CWM 6.0.2.3 cannot mount sdcard as well. But I cannot flash another recovery neither.

Try this,
When in recovery (CWM) connect to pc with usb cable and open command prompt (run as admin) & cd to your android-sdk\platform-tools folder and run command
Code:
adb devices
if it does not return your device s/n then adb is not setup. Here is a good how to, just follow on from the device manager part if android-sdk & java already installed
Once adb is working run command
Code:
adb reboot-bootloader
and see if that does the job.
TWRP 4.2.1 modified - Will not mount Sandisk ultra SD

The only SD card I can mount now using the modified TWRP 4.2.1 is my old Sandisk 2g (FAT) Works just fine (installs, backups etc.) This card works actually in many other JB TWRP versions fine as well.
I had a Sandisk Ultra 8GB MicroSD (micro SDHC) class 10 in my Tf300t prior to update to 4.2.1 which worked fine then in twrp recovery. No version of TWRP will mount this card now, uncluding the above mentioned version.I have tried for days now, tried several partitioning tricks, formating etc. Just does not work.Card works fine when JB loads and I can use it okay in the o/s, just bombs in Recovery. I also have a 16gb Sandisk ultra 10class, no go there as wel in recovery. Stuck witht the 2GB card so far.At leastI was able to root my tf300t now on US 10.6.1.8 firm. via the 2gb card using TWRP 4.2.1 installing UPDATE-SuperSU-v1.25.zip .Also was able to do a backup on the 2GB card. So all is working great, just stuck with 2GB SD for now I guess.
Anyone else having this problem using the mentioned Sandisk Ultra SD's or other types ? Any info or updates to a fix on this ?
Thanks,
Julian
I also have this issue with 64gb class 10 & from what you say above it now makes me think the "external sd won't mount" issue is class related, not size & class 10 cards will not work in twrp on the new 4.2.1 (10.6.1.8) bootloader - but do work on 4.1.1 bootloaders.
Modified TWRP for 4.2/10.6.1.8 bootloader:
Sandisk 64gb microSDXC class 10 won't mount
Sandisk 8gb microSDHC class 10 won't mount
Sandisk 16gb microSDHC class 4 mounts fine
Sandisk 8gb microSDHC class 4 mounts fine

Thanks that worked. Actually I tried it before without success, but now with the universal drivers it works.
So now I'm able to get into bootloader. However cannot flash anything. When I fastboot the process goes fine but the device seems to freeze and at the end of the process 'fastboot reboot' command does not reboot the device. I have to manually reboot it holding the power button. It then reboots again into CWM and i have to adb it to the bootloader again, thus the flashing is not working.
Any suggestion? Thanks!

I have a G-tablet and it does not work usb storage.
I try to install the bootloader external micro sd card, and now he does not enter the boot screen.
will be to have some output? remembering that I can only use the external micro sd.
awaiting.
Your problem description is not very clear.
Are you saying that your USB port (which one: micro USB for adb, or the standard slot for USB peripherals?) isn't working, and that you want to install something using your external SDcard?

1. Do you want to install the ROM from the external SD card to the standard partitions on the NAND flash and internal SD card?
OR
2. Do you want to install your ROM from the external SD card to non-standard partitions--like on the external SD card itself?
The first is very easy. Most ClockworkMod versions will let you choose a zip file from the external SD card.
The second option is will need modifications to the ROM package itself.
option 2

1. As far as I know, on the gTablet, the bootloader will only work if it is on a standard NAND flash partition. It cannot run off the SD cards.
Simiarly, both the recovery image and the ROM kernel has to live on the NAND flash. The ROM itself (apps and data), however, can exist on either SD card.
2. You can install a ROM if your gTablet can boot into recovery mode (either CWM recovery or the standard recovery).
A new bootloader can be installed (without using the USB cable and the APX mode) only by the standard ViewSonic recovery. CWM recovery won't do it.
3. You can install either of the recovery images (CWM or std) using either recovery mode, or by using any of the custom ROMs.
Ie. If your mini-USB port can't be used for APX mode, the tablet must boot either into the ROM or into recovery mode.
4. A bootloader and a ROM can also be installed in APX mode, but, for that a working USB port is needed. If your mini-USB port is not working, open the tablet up and inspect the mini-USB port carefully. Also try using a different computer and USB cable.
hi guys, i got an issue about the external sd card mounting. my m2 can't mount external sd card. here is what i tried:
- i tried 3 different sd card. NOPE
- wiped everything and tried another custom roms. NOPE
- even in TWRP recovery mode, external sd card can't be mounted.
- i've changed the sd-simcard reader of the phone, issue is the same. sim card is working perfectly but no sd card.
- now i'm downlading lastes ftf file for single sim but just im trying maybe it will work.: NOT WORKED
what may be the problem? hope you help me because i'm done with a new possible cause confused:
cmon guys i need a suggestion
