I think I'm starting to understand this flashing recovery thing, but it doesn't seem to be working.
So I have downloaded the latest CWM and TWRP for my device (crespo?) and put the .img in a folder. I've tried both CWM and TWRP separately to no avail. I put the mac-related fastboot and adb files into the same folder. I open the terminal and flash the .img. I would like. It runs and says 'OKAY'.
Now, when I power down > hold volumne up + power > it brings me to the 'FASTBOOT MODE". It shows me my lock state is unlocked and gives me the option to:
REBOOT BOOTLOADER
REBOOT
RECOVERY
POWER OFF
So I select RECOVERY and this is where it gets weird..
Reboots and brings me to a screen with the android guy lying down and a red caution triangle coming out of his chest. If I leave it, it will eventually reboot normally. If I hold the power and volume up button again for an extended duration (or some combination of buttons, i usually just hold random combinations until something pops up), then i get the 'android ssytem recovery <3e> screen. It looks like a minimal CWM recovery screen with Reboot system now, apply update from ADB, apply update from /sdcard, wipe data/factory reset, and wipe cache partition.
This doesn't seem like the CWM or TWRP that I flashed. It also won't let me flash a ROM when I select 'apply update from /sdcard'.
I'm pretty sure I'm not installing CWM properly.. but when I run the terminal (command prompt) it seems to run fine.
Does anyone have any suggestions?
SOLVED:
So I messed around and solved my problem. Apparently entering CWM recovery on the Nexus S is more challenging than it should be.
For those of you with the same problem, here is the solution:
Enter fastboot mode > connect your device > open your command prompt (terminal)
I would flash CWM to your phone first fastboot flash recovery <recovery.img>. When it finishes and tells you everything is okay, type:
fastboot boot <recovery.img>.
This will boot your phone into CWM recovery!
Hi, this is a first time root for me on my Asus Transformer Pad Tf300t.
I followed the rooting options, and all went as planned.
I then tried to install Google apk's through recovery and it all started to fail from there.
All the apk's were failing after flashing into Cyanogenmod 12.1, so I decided to remove the apk files and reboot. Somehow they were still installed so instead I tried to factory reset the device, but upon doing so I now can not boot into recovery.
All I get is the team win logo screen that stays on for a few seconds flashes off and repeats.
No force reset, not hard reset, nothing.
I have zero experience with the technical side of rooting, and therefore have no ideas how to fix the issue myself. If anyone thinks they can help me, please let me know!
get latest twrp and fastboot binaries (you might have them already for rooting)
boot into bootloader:
a) open terminal and type in:
su
reboot bootloader
b) power down tablet
boot it up with vol- pressed
etier a) or b) should leave you with 3icons (RCK, android, wipe data) - stay on that screen
plug tablet to computer
make sure it is detected by typing this into terminal on your computer: fastboot devices
fastboot erase recovery
fastboot flash -i 0x0b05 recovery path_to_twrp_blob
example:
fastboot flash -i 0x0b05 recovery c:\stuff\twrp.blob
wait till it is done (should see blue bar on tablet screen)
then reboot rablet:
fastboot reboot
let it boot to system, then reboot back to recovery - should work this time (not sure if boot to system is needed at this stage, I had one time issues with recovery when not booted to system first but that might have been faulty flash and not procedure failure)

hi, I don't understand the procedure for booting in recovery......I have the following trouble: I updated my TWRP recovery by itself recovery , from 2.8.4 to 2.8.7 following the instruction on the site TeamWin. Afterhand I can't go in the recovery mode e for this I can't flash other Roms. Is it possible to solve this problem?Thank's
Do you have ADB on your computer and does it see you tablet?
If so, while the tablet connected with USB cable, open up Windows command prompt, and issue command:
"adb reboot recovery".
Or within Android, install Terminal Emulator app (I found the best one to be by Jack Pavelich). Open it, type:
"su" and allow root
then:
"reboot recovery"
That will get the tablet, or any Android device, reboot into recovery mode.

How to get out of a boot loop

I had that same problem last week, and I managed to resolve it.
My mistake had been to omit that reboot after unlocking the boot loader, so I got into that same boot loop with booting to recovery (TWRP) -> TWRP throwing errors -> TWRP causing a reboot -> rebooting into recovery again -> same error -> reboot -> etc. etc.
Here is what you can do (at least it worked for me); thanks also to the helpful people in the TWRP IRC channel on freenode:
Power the phone down during a boot loop:
It is not necessary to wait until the battery is completely drained by
rebooting hundreds of times.
There is a small time slot where the phone should accept "adb" commands during rebooting. So there is a chance to submit an "adb" command if you just send it over and over again. It may take some reboots to catch that time slot, but if you do it often enough, it should succeed at some time.
This worked nicely for me:
Make sure the latest Android SDK is installed (which includes the "adb" command).
Connect the phone to the PC with via USB.
While the boot loop is in progress, open a shell window on the PC (using
Linux in my case) and enter this command:
sudo adb shell reboot -p
(without "sudo" for Windows users - did not try that)
Repeat the command over and over again.
Use [Cursor Up] to repeat it from the command line history.
Do this until the phone's LED lights up and it shows a large battery logo on the display to indicate that it is powered off and charging.
! This might take many repeated attempts, don't lose your patience !
Disconnect the phone from USB.
Reboot into fastboot mode.
If TWRP is installed, this is [Power]+[Vol+].
If the stock recovery is still active, this is [Power]+[Vol-].
Break a boot loop that keeps booting into TWRP recovery
Make sure the latest Android SDK is installed (which includes the "adb" command).
Connect the phone to the PC with via USB.
While the boot loop is in progress, open a shell window on the PC (using
Linux in my case) and enter this command:
sudo adb shell rm "/cache/recovery/*"
(Without "sudo" for Windows users - did not try that)
Repeat the command over and over again.
Use [Cursor Up] to repeat it from the command line history.
Do this until the boot loop stops, i.e. you see the TWRP screen, and it does not keep booting any more.
! This might take many repeated attempts, don't lose your patience !
Reformat the /data partition under TWRP's "Advanced" options.
Just trying to wipe will fail at this time.
Reboot into recovery once more (TWRP -> Reboot -> Recovery).
Wipe (TWRP -> Wipe; the normal wipe which wipes data, cache, and dalvik).
Reboot the phone to system (TWRP -> Reboot -> system).

Hello,
How do you do to unlock bootloader.I was able to download and patch with magisk the last ROM but I can't flash it !
Please would you tell us how you do that ?

2. then on the tablet go to settings / Developer mode / usb debugging
3. connect the tablet to pc with usb cable then on the tablet you will see usb debugging authorizations, click on allow always to make the device debuggable
4. on pc launch command prompt then type "adb reboot bootloader" to reboot into bootloader
5. once in bootloader type "fastboot flash recovery "the directory of the twrp-recovery.img" once flashed then type "fastboot reboot"
6. once tablet rebooted type "adb reboot recovery" on pc to reboot into recovery, warning you will see /data mounting errors to fix this on the tablet go to wipe / format data and type yes to format data, then go back to main screen then go to reboot / recovery to reboot back into recovery.
7. on pc download dm-verity-forceencryption zip file here http://www.mediafire.com/file/ndhe4ewlzlffdur/Disable-dm-verity-forceencryption.zip/file then on the tablet go to advanced / adb sideload then swipe it, then on pc type "adb sideload the directory where you put the zip file" once flashed then go to the main screen then go to reboot / system to reboot system

Working fine from my side
Turbo, many Thanks!
It works perfectly ! ?

Good job, @turboperson123 ! @Monpseud0 pointed me over here.
I've got some time this week & I'm going to start on a version that will handle encryption. You can find the device tree and code here. I've included a link to this thread.
I bricked my device. Rebooting the system from TWRP only gets me back into TWRP.
Am afraid I will have to flash a new rom.
Does anyone know where to download a working rom for TB-X065F
Help much appreciated.

Easiest thing to do is use LMSA. It's available on Lenovo's support page: https://pcsupport.lenovo.com/au/en/...r-list/component?name=Software and Utilities.

I can download the ROM through LMSA, but not flash it.
Trying to do so yields a "complete" message from LMSA after only a few seconds, but then rebooting the device only gets me back into TWRP.
I also tried to flash all system_xx.img from the ROM using fastboot flash system system_xx.img ,
and to flash all vendor_xx.img from the ROM using fastboot flash vendor vendor_xx.img.
Fastboot performs this operation, but then rebooting gets me back into TWRP again.
Trying to reboot the system from TWRP yields the message "no system installed"

Tough one! Try this. It will wipe your data partition, though.
If it will let you, power down the tablet for about 10mins. Then boot into TWRP. Go to "Wipe" and swipe for Data/Factory Reset. Reboot.
If the M10 still won't boot, in TWRP re-format Data (by typing 'yes' under Wipe->Format Data), and wipe cache and Dalvik Cache. I think dalvik is under Wipe->Advanced. Factory reset again. Reboot.
As an absolute last resort, you might try fixing permissions in TWRP under "Advanced". But I don't think that's going to do much, because you haven't booted the ROM successfully yet.
Hope one of these works for you. Let us know what worked for you. If nothing works, PM me and we'll try some other things.
Lenovo Logo THEN black screen -- DEAD

I followed the instructions but on the last step of rebooting to system the device restarts, shows the Lenovo logo then it goes to a black / blanks screen. It appears to have shut down. I must hold the power button for several seconds before it wakes up (or restarts?) and does this all over again -- shows the Lenovo logo then black screen.
For the record the device was already rooted with Magisk. I was just trying to do a TWRP backup but found /data mounting errors so tried following steps 6 & 7. At the moment the device refuses to boot up. I am unable to get back into Recovery Mode. The ONLY thing i can do is get into FASTBOOT mode and issue commands from CLI.
The following hardware key combos produce the same results -- tablet turns on to show the Lenovo logo, after a few seconds the screen goes black (the device appears to have turned off):
x Power key
x Power Key + Volume Down
x Power Key + Volume Up
x Power Key + Volume Up + Volume Down
** Release of keys is done once Lenovo logo appears
Any ideas?
UPDATE
I went ahead and performed: fastboot flash boot boot.img << the boot.img was the earlier patched magisk image i used to get the rooted working tablet.
After performing the above the tablet turned on and is now showing the Lenovo logo however it does nothing else --- it remains on the logo forever. I am able to get into TWRP recovery. I went ahead and wiped Dalvik, Cache, and Data. Rebooted to System but still it is stuck on the Lenovo Logo.
The device if fully charged.

You could try recovering the tablet with LMSA. See this post. You'll lose all your existing data and setup on the tablet, though.
Not sure what went wrong for you. Do you have a TB-X605F with Snapdragon 450 SOC? The existing TWRP is only for the SDA450. I'm working on one for the M10s with SDA429.

Thanks for the response. Yes mine has the Snapdragon 450. I will investigate the LMSA. Been messing around all day but made no progress -- not even QPST is working out.
