[Q] problems with clockworkmod recovery (device almost dead)

ok, so i wanted to try Cyanogenmod 7.
i followed the steps:
1- rooted the device
2- downgraded to Froyo firmware
3- installed Cyanogenmod 7.20.
all worked fine for almost one week until i updated rom manager from the market.
since the the device led flickers in green and orange. I can get into clockworkmod recovery menu but it lasts for a few seconds and disappears. it appears again and so on.
adb devices returns:
List of devices attached
SH0BHRT09137 recovery
but because it's not stable the same command doesn't return any devices few seconds later.
what shall i do now ?

steps one and two i assume are switched around, try booting into fastboot
if your hboot is still stable you may have more luck here
fastboot works in similar ways as adb - so fastboot devices
if you see yours
then wipe and flash a new recovery via fastboot
fastboot -w
fastboot flash recovery recovery.img
fastboot reboot
(replace recovery.img with whatever name you give that recovery image)

Thanks for the info. after i installed fastboot and ran "fastboot devices" i don't get any devices.

are you in fastboot mode within hboot? does your phone say fastboot usb?
write down everything on your phone when you boot into bootloader

strange enough "adb reboot" go the device working ! not sure why it was stuck at ClockMod.
hope this thread help somebody later.

Returning to stock

Wanting to go back to stock on the nexus 7. I have downloaded the factory image but for the life of me cannot figure out how to flash it. I am in the bootloader and i've extracted the image to my adb and fastboot directory. there is a "flash-all.sh" file but I'm unsure what to do with it. Any help would be appreciated. Thanks.

I personally don't remember how to use the .sh files.
But open the file with a text editor such as Notepad++, and you'll see the commands the script will run. You can run them manually.

sh files are purely for Linux users (it's the equivalent of batch files in Windows). Just run the commands in the sh file in your command prompt (or alter them so that it matches your fastboot).

I downloaded the images and looked at the script. Here is what it does.
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-3.34.img
fastboot reboot-bootloader
<Wait for it to reboot>
fastboot -w update image-nakasi-jrn84d.zip
And you're done.

Thanks to all three of you. I am now back to stock. I appreciate the help at this crazy hour in the morning.

Are you still stuck? What is going on at the moment? What have you tried? PM me if you would rather.

Ya I'm still stuck....tried using wugfresh toolkit to get back to stock but drivers ain't working correctly. I'd rather just flash stock Google image if possible and be done.

Can you use ADB and Fastboot???
Do you know how to use ADB and Fastboot???

If you are stuck returning to stock, I have just posted a full guide in the development section. I just did it myself to make sure that it works. Enjoy.

Secure boot is enabled on all Nexus 4's, and you cannot disable it. By the way, Secure boot has nothing to do with the lock state of the bootloader -- it has to do with the secure boot chain of the AQP8064 chipset.
Unlock the booloader using "fastboot oem unlock" and then flash the factory images. See here.

If simply flashing factory images, an unlock should not be necessary. Is customer wanting you to try and preserve data?

Thanks for the answer but the wierd problem is that after I unlock the bootloader and try to flash any thing I get":
sending 'bootloader' (2188 KB)... FAILED (command write failed (Unknown error))
Click to expand...
Click to collapse
and after I reboot it shows that the bootloader is locked

I managed to boot into twrp recovery but no screen by "fastboot boot recovery.img" and I get adb access.
ant thing I can do from here ?

You are seeing a black screen because you are not using the correct command. It should be: fastboot -c "lge.kcal=0|0|0|x" boot recovery.img

cwm can sideload but wipe will give errors (cant mount) and after reboot the bootloader is locked againg and wont boot.
stock just reboots.
can it be HW ? or any other solution ?
btw where did you learend this switch and where can I read about it ? "lge.kcal=0|0|0|x"

Two options before we decide it's hardware.
Procedure #1:
1) Download the LATEST version of fastboot.exe from here and extract it to C:\android.
2) Download the latest factory image from Google's dev page and verify the checksum with what is posted on the website.
3) Extract all the images from all the .tgz, .tar, .zip files within and put the 6 image files in C:\android
4) Reboot your device into the bootloader and plug into your PC.
5) Open a command prompt in that same directory and type the following commands:
Code:
fastboot oem unlock
fastboot reboot-bootloader
fasltboot flash bootloader bootloader-mako-makoz20i.img
fastboot reboot-bootloader
Does that work? If so then continue with flashing the radio, boot, system and recovery images. If not, then go to procedure number 2:
Procedure #2
Follow the instructions in this thread.

Cant make the NPST recognize the phone ;\
while booting custom recovery I cant mount any partition and the bootloader remains locked after reboot.
Any thing else to try ?

Boot Loop - ZE550KL

Hello guys,
Sorry for my bad English
My phone just turned off even if the battery is almost full. When I turned it on its stuck in a boot loop. Sometimes it's goes to a screen where it would say process not responding. It's still on the stock ROM and recovery. I didn't try to root it or flash anything on it.
I tried some troubleshooting like flashing the firmware from the Asus website but it didn't work. Please help

Have you try flashing from Micro SD card in stock recovery?

Thank you for the reply bro. I already did and it's still not working.

To reset the phone in cases like this, one could also use fastboot.
Boot in fastboot mode by pressing VolumeUp button while switching on the phone, then connect the phone to a PC with a usb cable (you must have fastboot/adb drivers installed). You can now open a command prompt and use the commands:
Code:
fastboot erase cache
fastboot erase userdata
fastboot erase system
The second command erase all the user's data on the phone.
The last command erases the operating system and you must install the full firmware in zip format from the recovery afterward (with a microSD card or with a PC via ADB sideload).

you can install custom recovery?

I had a boot loop issue too. I could solve it by entering fastboot and trying using the defaut roms boot.img through fastboot. You can extract the boot.img from any firmware image file from the Asus site.
Code:
fastboot boot boot.img

After these commands, had to do a wipe data/factory reset prior to update from sd card (adb sideload not work at alll).
but no luck, keep boot looping...

maybe you should unlock the bootloader before trying those commands

why don't u try, adb sideload option once, give it a try

i dont know what firmware my dads ze550kl is...
and it is bootlooping continously....

i want to save my dads internal memory

Try this:
fastboot boot recovery.img

This may result an error if you don't flash the right file,it depends on your firmware version. I have a file that works on lolipop (twrp.).

I had the same issue, as my device was on warranty period i took it to the service centre and they said the mother board is damaged

Im facing the same problem I installed a new ROM from SD card and it was successfully done but the phone is still stuck in boot loop and unfortunately my USB debugging is disabled my bootloader is locked and my phone is not rooted and it's in stock recovery can anyone please help me

heyy, even i deleted recovery by using
fastboot erase recovery
then, after that my phone stucked on fastboot mode..
and when i flash the recovery , it finished propery but there is nothing happen in my phone still stucked into fastboot mode..
when i press power+volume(-) only fastboot mode is opened..
what to do now??
how to reinstall bootloader (recovery or twrp)??
plz help guyzz//:crying::crying:

I face the same bootloop problem with my mother's cellphone. The bootloader is locked and USB debug is disabled.
I tried to flash stock img via adb sideload, and although it succeed, after factory reset in Recovery (and pull battery several time) I could finally get into the "setup wizard" of Android system.
However, the system will go into bootloop again when the wizard goes to "wifi" setup. The phone will not go into setup wizard again unless I do a factory reset (and battery pull) again...
It seems there are some hardware failure at Wifi component (Since I already erase all \data, \cache), and this failure caused reboot of the system...
Any idea?

Try flashing stock ROM using fastboot
use Huawei update extractor select boot ,system,cust,recovery ,extract them and flash them with fastboot like this
fastboot flash system system.img
fastboot flash boot boot.img etc....
just make sure that you place those img files in same folder as adb is.

Seems like your boot image is damaged but check this thread maybe it helps https://forum.xda-developers.com/p8lite/help/stuck-rescue-mode-screen-please-help-t3244872

usually you should always get into fastboot mode. Turn off your phone, connect it to PC, press power and volume down, after screen turns on release the PowerButton and keep holding VolumeDown, until you are in fastboot mode. Then use fastboot to flash a new boot, recovery and system

Hello all,
I have a similar problem on my old P8 lite phone, but I can enter into fastboot mode. No idea how it turned out like this... I bought a P20 lite and stoped using P8 lite for several months. Some days ago, tried to use the phona and it was unresponsive. Wiped data and some more options, and the phone got stuck on rescue mode.
I've read this and other threads and tried to use fastboot to flash stock ROM again. I downloaded update file, extracted boot.img, system.img, cust.img and recovery.img but when I try, to start flashing boot.img I get:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash boot BOOT.IMG
target reported max download size of 471859200 bytes
sending 'boot' (22688 KB)...
OKAY ( 0.588s)
writing 'boot'...
FAILED (remote: Command not allowed)
finished. total time: 0.592s
When I enter fastboot & rescue mode I get the messagem "PHONE Locked" (green letters). What can I do to recover the phone?
TIA for your help.
