I have Huawei ascend u8681, It's rooted and on stock rom as there are no other roms for it and bootloader is currently locked. Whenever I try adb reboot bootloader or recovery, I just reboots normally. I was wondering if there's a way to activate recovery on this phone. The reason is that there are some better adreno 205 drivers available for this phone than stock that I'm trying to install them via adb shell but I need it in read and write mode in order to do that.
[edit] recovery is working, I've just been using the wrong adb command this whole time. I was using adb reboot bootloader instead of adb reboot recovery.

I'm actually not new to adb or Android. I've had a rooted HTC Incredible since January and I'm quite familiar with adb, but when I run adb reboot recovery on my Galaxy Tab 10.1 the tablet shuts down instead of reboots. That is kind of annoying as I don't have an easy way into recovery other than the power+vol down method.
Do the reboot apps from the market that support recovery reboot into recovery for this device?
if you're rooted, try this
Code:
adb shell
su
reboot recovery
I had the same problem and loaded pershoots su package in the dev thread and it gave me the ability to reboot recovery,,, I am pretty sure you need this to adb reboot recovery. Hope it helps

What about if my tablet is not rooted yet? I'm having the same issue
Regards!
you need a rooted boot in order to send adb reboot recovery/bootloader.
I have a UK-bought SGT10.1, which I rooted shortly after purchase and installed CWM Recovery using Odin. I've been running In Paris for a while, and was about to update to v5. Last time I downloaded pershoot's kernel from droidbasement, I saw an updated version of CWM Recovery here: http://droidbasement.com/db-blog/?p=2370.
Being a security-type, running the latest versions is always the best option to me - and seeing I know my way around the console I figured I'll install adb/fastboot and use that this time instead of Odin. So I downloaded the SDK, installed the Tab 10.1 drivers (I've reinstalled Windows since I rooted), and grabbed the fastboot .exe from the previous revision and placed it inside android-sdk\platform-tools next to adb.
Now I'm trying to follow the instructions to install the extracted .img - but having some issues getting into fastboot mode in order to execute the commands. Running adb devices results in expected output, as does adb reboot recovery. However running adb reboot bootloader causes the device to reboot all the way back through to the lockscreen. I see some advice stating that to manually enter fastboot you reboot the device holding power+vol down, then pressing down to switch to the second option that isn't download mode. However that to me is the option to manually enter CWM Recovery, so now I'm confused. Running fastbooot reboot-bootloader cause
I don't want to brick my device, so I figured I'd ask for some advice here for getting into fastboot mode, and ask whether I can just flash the .zip inside CWM Recovery or if that is a very risky move?
Thanks in advance
The scenario is that:
I purchased for the past year, ChainFire3d and found out to be effective. And right now I got a new phone and got it rooted. BUT, I forgot its running on 4.2.2 and ChainFire3d doesn't work on it. So, I am stuck on boot screen
I tried the following:
ADB commands to uninstall ChainFire3d, but in 4.2.2 roms, adb doesn't work in stock recovery for it has already have an alternative "update by adb support" which will let you go to adb sideload. And adb sideload mode doesn't support any other adb commands except sideload.
So, I tried to download a stock rom from a site, and tried to install it by "update by sdcard" and it says "Installation aborted" maybe because the stock recovery doesn't support the updater-script.
So, I tried fastboot, but fastboot cannot detect any device because stock recovery doesn't support adb.
And alas, I am out of options here.
Please help, somebody.
BTW, my phone is Lenovo A369i
OK... I managed to fix it.. after like... 10 hours .. whew
if you're wondering how I did it... here's how

Hi,
I was trying to restore oxygenos on my opx.
I connected through adb and tried flashinf a recovery. The flash was unsuccessfull and I was left with my custom CM recovery(which cannot install roms due to some error). Now i tried flashing new recovery again but OEM is locked. The command for unlocking just reboots my device from fastboot mode to recovery mode.
Also, I no longer find my device using adb devices command.
Please help

Not enought infos to help you.
The most direct way is to perform the Mega Unbrick Guide.

Hello comrades.
After 5 years, I finally got tired of being on Android 4.2.2. I thus started to look for a custom rom to maybe upgrade it to 5.1? I found nothing obviously. Except a whole bunch of problems including: my phone can't even go into recovery mode. (And Twrp and Cwm just stop working when they have to look for my phone model.)
My idea is this one: I'll dl Android Kitkat, lollipop and nougat and starting from nougat, I'll see what my phone can and can't support so at least I'll upgrade some part of my phone. I also know I'll have to bear in mind the Linux kernel and try having the best one considerning my ol' Archos. Question: do you think it's doable? That I can make it? P.S: my computer is on Windows 10.
Of course, if you happen to know a lollipop version for an archos 40ti I'll be glad to take it!

Each phone by default comes with a Recovery partition, unless it got removed by whomsoever.
Anyway, if ADB and Fastboot fully are working, you can boot phone into a Custom Recovery ( TWRP and/or CWM ) and from there flash a Custom ROM.
Of course phone's bootloader must got unlocked before - what causes a complete data loss:
Code:
adb devices
adb reboot bootloader
fastboot OEM-unlock
fastboot reboot
If the above step was successful then you can proceed booting phone into CWM recovery ( DL here )
Code:
adb devices
adb reboot bootloader
fastboot boot <FULL_PATH_TO_RECOVERY_IMAGE_ON_PC>
Again: The above Fastboot command will just boot your phone CWM. To permanently install CWM recovery, you have to run
Code:
adb devices
adb reboot bootloader
fastboot flash recovery <FULL_PATH_TO_RECOVERY_IMAGE_ON_PC>
If also this step was successful you can install any Custom ROM of your choice via CWM recovery.
Thanks for the reply!

They are not (which is a problem I consider for another day when my custom ROM will be done haha)
Here's the commands I tried the other day: (spent one whole day trying to install CWM/TWRP)
adb devices > worked
adb reboot bootloader > worked
fastboot OEM-unlock > nothing happened
fastboot reboot > worked
Click to expand...
Click to collapse
Nonetheless I try flashing the CMW recovery img
adb devices > worked
adb reboot bootloader > worked
fastboot flash recovery <FULL_PATH_TO_RECOVERY_IMAGE_ON_PC> > sent back an error message : "partition "recovery" not support flash"

Since holding volume down+button on/off could not send my phone into recovery mode (it just turned on), I used:
adb shell > worked
reboot recovery > sent back message : "reboot : Operation not permitted"

Anyway, there is no custom ROM for my device so I don't have any choice but to do it myself - and first, I need to find out how to get the source code of my current kernel.
