Z2, Can't boot into recovery, no LED lights.

[david_Vi]

Hi, i've had my Z2 two years now and I've rooted, UB and installed roms on it many times but for some reason I can't get into recovery anymore. I flashed a different ROM a few months ago to try get it back to stock but since then, no recovery!

I've flashed the TWRP 1 click installer (only seems to work on laptop, on PC I get waiting for device but it says it worked on laptop) but still I can't get into a recovery to flash a custom rom.

Any ideas? How do I get recovery back? Please be a bit simple with me, i've googled it and just get overwhelmed by the info so figure I should ask and find out what actually applies to me..

Thanks.
David

If you have flashed a stock rom, you probably have locked your bootloader, try this (hope you have done a TA backup the first time you unlocked the BL...):

Download the Androplus kernel in development section, unzip it.

Then, download and use flashtool (install the drivers if need them) to unlock your BL again (BLU button).

Once you have unlocked it, disconnect the phone from the computer BUT DON'T BOOT IT.

Close and reopen flashtool, and select fastboot mode from flashtool and use the kernel flash option.

Select the boot.img you have unzipped from androplus (change the file extension to .img), and your are done.

Disconnect, reboot and you will be able to access the TWRP recovery from the kernel when you see the led, then flash a stock based custom ROM (with recovery), or CM one, try to have one of them downloaded and placed into your ext-sdcard.

PLEASE! My English is not good enough to explain this in a better way, if you don't are familiar with flashtool, fastboot mode or you don't understand any of the steps, wait for a better explanation or read a lot about it BEFORE doing nothing.

PS. Your internal data probably will be lost, make a copy of all your photos, docs, etc. You can relock your BL if you choose a stock based custom rom like eXistenZ, just restoring your TA backup after flashing it.

have u try flash via adb fastboot? it's easier when u have UB, try erase it first, "fastboot erase recovery" then flash the img (the latest twrp img is available on their site) "fastboot flash recovery recovery.img"
