Can't recover my N1

this is what i tried to do: wanted to flash a new rom from my original froyo. read through the guide and got it rooted and installed rom manager and in turn installed recovery. booted into recovery and made a backup. tried installing a rom but it wouldnt let me so at the end installed RA recovery instead. i was able to flash a different rom. mpw tried to boot to recovery to get stock rom it display just the android and exlamation mark.
i can get into bootloader but in recovery wont show a thing as if it lost the recovery program.
tried installing sdk but adb wont see the phone.
SDK version 9, windows vista
Any ideas?

You have the stock recovery...
Read the wiki. Follow the guide for unroot/restore, using passimg method and FRG33. Start again rooting (though you probably want to read a bit more first, and make sure you can connect via adb and fastboot BEFORE you mess with stuff)...

issue is i cant connect through adb or fastboot since i dont have the debug mode before it all went

You don't need adb or fastboot to follow the unroot/restore guide. I was simply suggesting that you make sure it works before you try and root again.
Unroot/restore.
Get adb and fastboot working.
Play with phone.

how can i get adb/fastboot working. i went through the guide and dozens of other websites.
adb doesnt see a phone connected even though under device manager it shows an android device.

Install the drivers when in fastboot mode, and you'll have fastboot. It's not adb.
fastboot won't help you unless your bootloader is unlocked. adb you won't get, unless you install a ROM and enable debug, or install a custom recovery - which, again, you won't be able to install without unlocked bootloader. adb doesn't work in bootloader mode, you should have found that in at least one of the "dozen guides".
So, you have 2 options:
1) you have unlocked bootloader or you want to unlock bootloader - in that case, enter the bootloader, connect usb, install fastboot drivers, install custom recovery with fastboot.
2) you don't want to unlock bootloader - then follow the correct advice given to you in danger-rat's posts above.

ok problem solved and thanks. all along the dll file for fastboot was in platform-tools instead of tool within the sdk hence why fastboot never worked. unlocked the bootloader and recovered my old image. incase anyone else have this issue.
thanks

Custom recovery problem

Hey so I currently have an unlocked bootloader and I try to flash a custom recovery via fastboot yet it hangs on < waiting for device > every time.
I have followed the cyanogen mod wiki step by step. It hangs on clockwork and amon RA. USB debugging is enabled. When I boot into recovery it says fastboot I then connect it to my computer it says fastboot USB.
I'm sure it will be some little setting that's wrong. I am currently running 2.3.4 stock, no root so rom manager is a no go.
I guess what I'm asking is does anyone know what I can do to flash a custom recovery?

Have you tried "fastboot devices" to make sure you have a connection?
What kind of computer are you using (Win/Mac/Linux)?

Fastboot devices gives an empty line the a new terminal line.
Also I'm running win 7.

My initial suggestion would be to update your drivers for fastboot. I have had this happen a couple times and a driver update resolved it for me.

That means your phone is not connected. Update the drivers, as suggested above...

Much appreciated I will try this when I get home tonight.

[Q] Can't use adb/fastboot while in bootloader, after flashing failed.

Okay so i tried to install a custom rom, but it failed, now when ever i execute adb reboot-boatloader the device goes into the boatloader but i can't use adb/fastboot as it doesn't recognize the device. I have windows 8, and it seems windows doesn't find the driver, but when I boot the phone normaly, i can access it using adb (but not fastboot). Any ideas ?
I still can execute the recovery option in the boot loader, but i have nor Zip file to install. I also changed the cid, so the stock rom won't flash.
Advice appreciated

I haven't use Windows 8, but so far I don't have any problem with Windows 7. I assume have already install the HTC driver. If not, you can install the HTC syn which comes with the driver.

Yes, I already installed the HTC drivers (htc sync +d rivers, then uninstalled htc sync, as it get's annoying while plugin on off of the phone)
My biggest problem is that, now fastboot is not running in bootloader mode, so I can't even flash an image or change back the settings i did.
(And of course seems like in bootloader mode, that windows can't find the phone).
So my Idea would be to flash a Zip.rom, like the over the air updates using the recovery option. It's just that i changed the CID to GOOGLE001. :/

Yes, you can uninstall it or use MSCONFIG to remove it on start up. : )
ok, have you try boot the phone in fastboot mode and type "fastboot devices" in command prompt?

Jep, so what i do is, i power the phone on, it boots into stock android --> adb devices works and retunrs my phonenumber (also the windwos driver is fine while in stock android)
i do adb reboot-bootloader and it starts into the bootloader (fastboot is turned off in the settings)
and then I'm stuck, Windows can't find the phone (get a bunch of errors with unsopoorted usb device)
also adb devices and fastboot devices is not working, so i tried to execute different commands like flashing or oem unlock,
but all i get is the message<waiting on device>

Are you on S-off?
Anyway, I would do the RUU. restore your phone and try again with a good custom ROM. Did you check MD5 with the rom you download? You still can connect your phone with ADB. That mean your phone is not brick yet. : )

windows 8.1 will not work on hboot below 1.54.000 (the only 1.54 that works is from the new GPE 4.4 update).
your going to need access to a windows 7 PC long enough to update your hboot to 1.55 to be able to use fastboot with your phone again. This usually only happens while flashing a RUU not A Rom. Flashing a rom will not affect your version of hboot

You are right, i can confirm hboot 1.54.0000 - i was flashing the RUU to convert my HTC ONE toa Google Edition.
So all I need is a windows 7 or lower pc to get fastboot running again?
That's good news, I would have searched for ages.

Yeah it's frustrating I know
If you use the 1.54.000 from the 4.4 GPe update it works also

Can't boot into recovery.

Hello,
So I have a P7 at B126. I tried rooting it with kingroot and tried to install TWRP. I got to the part where you have to use fastboot to flash the img and it fails so I gave up. Now I am trying to get into recovery and I can't. It just either goes to a black screen or a Boot failed screen.
Thanks in advance

Hi, I'm a little confused right now. Explain what you did so far a bit more detailed, so we could help you.. Which instruction were you are following? What was the exact error? Is your bootloader unlocked? Can you boot normally?

I can boot normally.
What I did was this.
I followed the guide to root my phone. Rooted it and then tried to install the TWRP custom recovery. It failed at the installing the recovery for some permission error. So I stopped trying to install it. Now I apparently don't have a recovery at all.
I also installed some root apps like SetCPU, Xposed(Which didn't work), SuperSU(Which didn't Work)
If I try to adb reboot recovery it just takes me to the boot failed screen with the android logo on it. If I try using the Power + Down button it just shows me the huawei ascent P7 screen and just go black.
Also when I go to the fastboot/rescure mode it says my bootloader is unlocked.
Thanks for the reply.

Ah okay. So, boot into the fastboot mode, put the recovery.img in the adb folder on your pc, run cmd and type 'cd c://..' (location of adb folder), then 'fastboot flash recovery [name of recovery.img]' (for example 'fastboot flash recovery recovery_twrp.img'). Now you should get a working recovery.
Are you sure you really got root access? Eventually due to this you got the permission error..

I do because adb has admin permissions but fastboot doesn't. I tried that with trying to flash twrp on my p7 but i get a failed error after like a second I the command. So I tried flashing a stock recovery and it throws the same error in fastboot.
When I type fastboot devices I get this
? fastboot
No id for my phone but adb sees it.

Ok, your pc does obviously not recognize the p7 in fastboot mode. Did you install the Hi Suite? Through this way you should get the correct drivers (maybe even update/reinstall). If this does not help, I think I can't help you, sorry. You may wait for more help or google what do when the device isn't recognized in fastboot.
Just flash the newest SuperSU.zip when you got a recovery.. That should fix problems with root apps/ the su binary.
Offtopic: I'm not sure if you noticed, but, you're running a pretty old firmware.. You may think about updating

Hi Suite installed and correct drivers are loaded(I hope) and yes thats why Im trying to get this fixed because it wont even let me update firmwares

Try on another pc.. You could also try flashify (look in Google play), but in case of a softbrick you have real problem. Do this on your own risk, most times nothing bad will happen, but it could!
I would recommend to flash the stock recovery, update up to B621 and then installing a custom recovery.

Hi mate.
1. Use your pc, Go shuame.com and download "rom flash program".
2. Enter fastboot&rescue mode and connect your phone and PC
3. The program will recognize your phone.
4. Download anyrom and flash by the program.
The process will not complete but you will have Shuame recovery.
But my case it didn't work properly
5. I downloaded CWM from here "pan.baidu.com/s/1dDq0qcT" password :bttc
Start this program with connect your phone and press nomber 1 and ENTER.
I don't exactly remember my phone was on fastboot & rescue mode or recovery mode.
But I could get recovery and did rom flash so it was fixed.
*****from: Godfrey Peligrino ---sorry i dont know how to post BUT, this guide helped me with my p7 L10 B619..just connect it to pc and let it boot over and over and when pc acknowledge you phone..click rom and just wait if not do it again..hope this will help you too..the writings is on chinese so just copy the english thumbnails before you proceed to download...(QUOTE) THANKS TO THE GUY WHO POST THIS....HE IS TOMODACHI5..

Can somebody please point me in the right direction? (I've searched)

I need to root my G4 on TMO. It's on 6.0 and all I have done is enabled dev options - usb debugging- enable OEM in the menu. I've rooted devices before but it's been awhile. I obviously need to start from the beginning here, I assume by unlocking bootloader. I can't find any thread to start with as they are either outdated or for a different version of Android, or I just couldn't find one. I would really appreciate it if somebody could just link me to the thread/guide I need to be in! Thank you so much if you can!

note it can only be unlock in this versions.. ill place them from oldest to newest 20i-(20p-20q-20r-20v) if you in any of the versions in parenthesis doent downgrade tp 20i... 20i is antirollback V2 all other in parenthsis is V3 you can switch bak and forth from 20p-to 20v.
well you have developers option enabled and OEM unlock
minimal adb. fastboot install it follow instructions. https://forum.xda-developers.com/showthread.php?t=2317790
download TWRP from here h811 and h815 same app for both. https://twrp.me/devices/lgg4.html
have 2 copies on in SD card other in minmal adb fastboot folder.
Bootloader OEM Unlock + Root:
Starting with the Android 6.0 20x bootloader it has to be unlocked, sorta like a Nexus, with fastboot. Previously only 'OEM Unlock' had to be toggled in Android Developer settings for TWRP or custom boot images to work.
download superSU
connect usb cable to phone.. then go to location folder of minimal adb.. ezample Crogramfiles/minimal.
then in the folder in a empty space press shift key.. and right click on mouse button . you should see open command prompt from here.. select it.
a new window should appear. enter this command
adb reboot bootloader and see screen for confirmation to acsess phone select yes.
if it doesnt boot into bootloader try command again
once booted youll see small letter on phone screen then enter command
fastboot oem unlock (this wipes ALL data!!)
it should restart phone. and optimize all apps...and bootloader should unlock
do same for twrp.... make sure command name of twrp is the same in the file example command is like this..
fastboot boot twrp-2.8.7.1-h811.img and file TWRP is say.. twrp.30.00 it wont work rename either command or files or both and name it twrp.img same in command. once it boot into twrp .. go to install then press button that says image. so the twrp.img you have in sd card appears/ select it then on next window tick recovery. swipe left to install permanently and you are done. flash new rom or superSU.
hope i make sense good luck

OK, I got twrp installed but the two SU's I've flashed don't work. I have SU installed, it needs to update binaires, I try that but it fails every time. Root checkers say I'm not rooted. I think I'm using the wrong SU zip. Any help? Your guide was great btw.
EDIT: OK, now it says i am rooted but I can't get the SU binary to update. It fails every time and then asks me to reboot and try again. Any ideas?
UPDATE: Ok, the SU binary finally updated successfully! I think I'm all good! Gonna check out some custom ROMS later. Any recommendations?
