The post is ageing but I had the exact same problem with an A700. I can go into recovery, perform some operations but no 'wipe cache' action for example, it reboots.
If I plug it in fastboot mode, it doesn't appear in the 'adb devices' list butI can flash different recoveries but not sideload any ROM.

hey,
i followed the tutorial in general to flash a factory image to my device, and all went well but now i want to install twrp again and it tells my my device is offline.tried it both in osx and windows7... is there a way to fix this?
thank you in advance
kind regards
You dont need adb to install a recovery. Go into the bootloader (volume down + power) and run "fastboot devices". If youre device shows up you are good to go.
You don't flash recovery with adb, you use fastboot. So do as chromium said to get to the bootloader, then "fastboot flash recovery recovery.img", where recovery.img is your renamed twrp recovery image.

Make sure that you go back and enable USB debugging again after flashing the factory image. Locking, unlocking, and flashing firmware images all will turn off developer options and USB debugging.
Oh, and when you connect your phone you will need to watch your phone for the security popup and allow the phone to trust and connect to the computer.

Thanks for clearing that up, but what can I do to fix adb anyway in case if I ever need it??

Did re-enabling developer access, USB debugging and allowing access from the phone's popup screen work?

I obviously did something wrong.
Well I did unlock my tablet and got twrp running, also installed the rom but next after the reboot it just doesn't work and i will get this message (see the picture)
After that i am sent back to the interface of twrp.

Hopefully somebody can help me!

YOU MUST BE ON THE ASUS STOCK JB 4.2.1 BOOTLOADER VERSION 10.6.1.14.x AND TWRP 2.6.3.2+ OR CWM 6.0.4.6+ BEFORE FLASHING THIS ROM.
This is copied directly from the Developers ROM.

You didn't use 'Wipe Data' from the bootloader, did you?
Read the OP for CROMBI-KK, compare it to what you did.
Describe in detail what that was.
"Does not work" is not very helpful...
Check if you can get into fastboot.

Well,
I can go to Twrp recovery and fastboot
I did install the rom with everything present I think.. had to select some things and finish the installing
after that I had to reboot and now i just get the image with the penguins.
Can I somehow go back to the original rom? to restart these things?

If you made a nandroid before flashing this, then yes, you should be able to restore it.
But let's take it from the beginning. Post your bootloader, recovery and rom versions.
As long as you have access to fastboot you can fix this, so don't do anything hasty.
And please be as specific as you can about what you did. We can only help you if we find out where you went wrong.

hm ok I will try
well, I didn't make a nandroid backup - my fault :<
are there specific bootloader? I was on JB 4.2.1
I am now on twrp v2.6.3.2 but I was while I did the flashing on twrp v2.6.1
hm I did flash crombi-kk rom from the OP
maybe I did some wipe before in twrp .. i think it was recommended?
so now I can't do any reflash or anything in twrp - everytime I want to do something there is this error:
E: Unable to open '/cache/recovery/.version'
I also can't get access to my external SD
Check if you can get into fastbot.
Long press Power and Volume Down until you see tiny script.
Read it and post the bootloader version: 10.6.1.14.?

All right, your bootloader is current.
I would recommend that you flash TWRP 2.7 in fastboot, then boot into it, do a Factory Wipe in TWRP (that can take upwards of 60 minutes) and flash the rom again.
Ok.. I tried but I got the answer
failed (data transfer failure (too many links))
hm I think I've got no connection, right?
well and now I get the message:
FAILED ( command write failed( invalid argument))

Alright, everything good so far.
Now download the TWRP 2.7 blob for the tf700 and put it into the same folder as your fastboot.exe.
Then issue this command:
Code:
fastboot -i 0x0B05 flash recovery twrp.blob
if that is successful
Code:
fastboot reboot
Then boot into TWRP via the fastboot menu.
Then you can factory wipe and flash the rom

I've got now twrp 2.7 and i did that factory wipe but nothing ever happens.. just the usual message

that's the message I everytime get - doesn't matter if it's a wipe or install or something else

is it possible to formate my complete data, because I think therein lies the problem, exept fastboot on my device and flash a recovery from fastboot?

If you want to try that, go to the Wipe menu in TWRP, then to Advanced and choose "format data".
In TWRP this can take 90 minutes! D not interrupt it and make sure the tablet is charged or connected to power.
But this will erase your entire data.
The recovery has it's own partition which you can erase in fastboot:
Code:
fastboot erase recovery
.
Then flash the new recovery. You could also try TWRP 2.6.3.2 if 2.7 doesn't work.

Your posted image indicates that simulation mode is active in TWRP - turn if off in TWRP settings.
To format data, it's approximately this: Wipe -> Advanced -> Format -> Data -> confirm
Note that it takes up to 2 hours to format and trim the eMMC.

Well I don't know how but it suddenly worked.. i could reinstall the rom but now it seems i am stuck in a bootloop between the picture of the four penguins and a bootscreen of crombi-kk with loading tiles under it
between these two the tablet is rebooting itself constantly
Go back to recovery and do a wipe only Calvin cache and Cache.

Hmm dangerous thing wiping data from the RCK menu with a custom recovery - not sure why you did that? What custom recovery and version were you on. There is a chance here that you have hard bricked it.

Which ROM (+version) did you install?

Did you wipe any partitions in TWRP?
What else did you do, e.g. which partition(s) did you format as f2fs?

TWRP V ==2.7.0.0 F2FS
ROM is CromBi--KK

what I did：
using Twrp formatting data then reboot to recovery to wipe cache （select only cache）
then flash That-F2fs kernel
reboot system
failed to start syst so I get fastboot mode
then I select wipe data（not RCK to recovery），is Bootloader wipe data
Now the tab stuck at twrp screen，and cant get in fastboot
PC can connect the tab but adb seems not working
How can I do?

OK You didn't need to flash the kernel and that maybe why it didn't start. The kernel was already built into the cromnbi-kk package - that was an older version.
Use my adb drivers for recovery below - unzip and install them from device manager whilst you have the device connected in TWRP.
You may need to manually wipe all partitions.
I don't have all the threads handy but look for Buster99 and his fix.
Or contact @lj50036 as he can fix you up

Hi guys
I have an edge s with a stock g100 firmware
can someone refer me to a guide that will help me install custom recovery?
right now I don't seem to have any recovery menu
In fact you can find all information here:
https://wiki.lineageos.org/devices/nio/
and here:
https://lineageosroms.com/nio/
Though:
You have to unlock your bootloader first with the unlock key from the Motorola website: https://accounts.motorola.com/ssoauth/login?TARGET=https://motorola-global-portal.custhelp.com/cc/cas/sso/redirect/standalone/bootloader/unlock-your-device-b
To unlock:
adb reboot bootloader
fastboot devices
fastboot oem unlock UNLOCK_KEY
Important:
Start point should be latest G100 firmware
Afterwards You have to flash additional partitions (see information in first two links)
Afterwards You have to copy a to be (see information in first two links)
To flash recovery:
adb reboot bootloader
fastboot devices
fastboot flash boot_a <recovery.img>
fastboot flash boot_b <recovery.img>
Where <recovery.img> is the name of the recovery you want to flash.
I would suggest the LOS recovery:
https://download.lineageos.org/nio
Then you can reboot into LOS recovery, format data and install LOS.
This is as I remember it when I did the first install.
Hope it helps... ;-)
thanks for answering, I really appreciate it
I've tried that guid on the LOS website but it threw my phone into a boot look after which I had no choice but to factory reset my device
I want to avoid factory resetting my device if I can
I've found another guide and would really appreciate if you could give me your opinion on it
Will the "fastboot format userdata" command factory reset my device?

Yes, it will reset your device.
And...why do you need custom recovery?
If you don't have custom ROM to install, custom recovery is useless.
If you want to install LOS then you need custom recovery for LOS, not TWRP.
May be my first post about installation experience will help also.
In fact I had the same experience; after installing custom recovery and LOS I had a bootloop.
Though, as you can boot in fastboot, it is not neccessary to factory reset; you can still do whatever you want... ;-)
