[G2 and Desire Z General] demkantor:
More advanced measures

The previous post only suggests basic technology "fixes." While i don't consider factory

reset a fix, the outcome may be you have a working phone. These few things mentioned

above are just the first steps in recovering your brick, ALWAYS start with the basics

before moving on to more drastic measures as you can cause further damage. Of course

you may have to do this to recover your phone,

my warning is to read up and ask questions!

Phone wont boot - no recovery

This is a bad sign, but in many cases flashing a new recovery via fastboot is all you need

to do. If you have an engineering SPL than proceed:

First do a test boot: boot phone into bootloader>fastboot mode>usb>open CMD

fastboot devices

See if your serial # comes up, if so proceed if not READ THIS (POST #3)

fastboot oem jump

Copy and paste the output, give it 5-10 minutes, if your phone sits at HTC splash then:

DOWNLOAD THIS RECOVERY to computer, extract the image noting the folder its in

Boot phone into bootloader>fastboot mode>usb>open CMD where recovery.img is

fastboot erase recovery

Note if there is an error or not

fastboot flash recovery recovery.img

If everything worked then:

fastboot reboot-bootloader

From here choose recovery, once rebooted go ahead and format all

*If you still cant boot into recovery post here!

Still i cant restore my phone!

Things are looking grim, but there still may be hope. If you have a working Hboot there

will always still be a chance. I always recommend ROOTING A PHONE RIGHT WHEN YOU GET IT

Even if your only reason is to recovery when things go bad, having an engineering

bootloader is just the cats meow. So unless your eMMC is fried, we should be able

to get you up and running again!

So fresh and so clean!

Wiping clean is great and formatting is even better. If you loose recovery access

it may be hard. Thankfully fastboot can help!

fastboot erase system -w

*I'm having trouble getting fastboot format and oem format commands to work,

I'll update this post when i see what the issue is.*

If you still have a working recovery do all wipes and formatting through it. Also try

and flash THIS SUPERWIPE SCRIPT and or THE AIO WIPE TOOL

When all is failing...

It is looking like you may have a fried chip, or at the very least some severely corrupt partitions.

An eMMC that has lost read/write capabilities we cant fix, not even with j-tag :crying:

But corrupt partitions can be fixed, usually by simply reformatting. I'm working on the

fastboot commands, but you can always reflash other partitions (like you did the recovery)

Check md5sums, and know what and why you are flashing, don't jump to this step

when you're in a bootloop!

HERE ARE SOME PC10IMG.ZIPS The post explains how to flash them trough your SPL

but you can open and extract the content and then flash through fastboot. Commands:

fastboot flash radio radio.img

This will give you the .19 radio only

fastboot flash hboot hboot_7230_0.82.0000_100902.nb0

This will give you the Desire Z engineering Hboot. *if you use the G2 one change the command

fastboot flash update PC10IMG.zip

This will the whole package (preferred over SPL flashing as any error will show in CMD)

*need to change command or change name of .zip

I'm not making this thread for :good: Thanks or 5star rating, I'm doing this to help out

others. XDA members have helped me so many times in the past that this is just one

of my small contributions. All i ask of you to be respectful and share what you learn

*Hope your up and running again soon!
