[Tutorial] Restoring Recovery Mode while working only Fastboot Mode*ALL METHODS HERE*

Hello!
Yesterday I found myself in a very terrible situation. I spend about 6-7 hours...
It just happened that I deleted the recovery (through fastboot), and before that deleted firmware of the phone. That is, there remained only mode HBOOT (fastboot). Around the internet and google there are no guides on how to return
recovery by the alternative methods or how to flash a new ROM through
fastboot.
Thats why i want to present to you my little guide... Coz i think it will be very useful for some ppls like me with the same trouble.
So, if you're in a situation where you do not have Recovery, and the phone is not started in boot ROM then first try a standard way to flash a new Recovery through fastboot mode
Standart way of flashing new recovery via fastboot​
1.Connect your phone with PC via USB and power off your phone (if it up).
2.Than start up in fastboot mode - (in my situation, fastboot mode is CAMERA+POWER, then button "send") in all other (as i know) this is starting the phone while pressing button BACK.
3.Open -> Start->Run->cmd (open command prompt in windows*) and write:
Code:
fastboot devices
Than you must see your device serial number like this:
Code:
H94XTGAMSHDY
and should say "fastboot".
If all right - go next. If not - check fastboot mode (is on?) and USB cable.
4.Than change directory via cmd to where you have saved your recovery image (NEW recovery.img !!! ALWAYS CHECK MD5 SUM)
5. Than type this :
Code:
fastboot flash recovery recovery.img [enter]
(while you are stay in the same dir where you saved recovery.img)
(if you got some error about previously version or smth like this you can try to use this: fastboot erase recovery and only than try to flash new recovery from step №5)
6.Check your phone's display, as recovery is being sent and flashed to your device. And check your command prompt/shell to make sure the process is over.
7.Reboot into recovery by holding Home and Power (before it power off device).
Thats all! You can use any recovery, all what you like. I use Amon_RA's recovery.
IF WHILE FLASHING YOU GOT :
Code:
sending 'recovery' <4594kb>... OKAY [ 1.734s]
writing 'recovery'... INFOsignature checking...
FAILED <remote: signature verigy fail>
finished. total time: 3.125
Use next steps (my Alternative method)
And IF you can't flash recovery by this method it is not big trouble as you think now
Alternative way of BOOTING new recovery via fastboot​ checked and founded by me
Everything here is much easier and faster!
Do not be scared as I did it yesterday
Only what you need it :
Change directory via cmd to where you have saved your recovery image (NEW recovery.img !!! ALWAYS CHECK MD5 SUM)
And than TYPE:
Code:
fastboot boot recovery recovery.img
And your phone will be rebooted about 2 seconds in RECOVERY MODE. Yes!
After this you can use your old Nand Back up (restore it) and start up your old ROM. Or you can wipe all and try to flash new ROM and many operations what you can use via recovery. When you will get working ROM and flash it - you can flash recovery via adb. Or Use Rom Manager (Not recommended!)
Why we use this method? Because if you got error while flashing - FAILED <remote: signature verigy fail> you CAN'T FLASH ANY .img. Why? I Don't know, i hope some android guru's help us with it theory
(ALL AFTER THIS LINE ALL TEXT COPYED FROM WIKI.CYANOGEN.COM CREDITS GOES TO Cyanogen. Thx you, god)
If you want to flash recovery via adb (using power on phone with working firmware) (This method working 100% but strongly need working phone with working ROM)
Working only with HTC DREAM (G1) - Attention.
adb method by cyanogen version
Restoring the custom recovery image
Download the flash_image tool (HERE LINK
Next, place the file on your desktop
Change the directory to where "flash_image" is located, e.g. in Windows: cd C:\<path-to-flash_image-location>, in Linux: cd /home/USERNAME/path/to/flash_image on a Mac: cd /Users/USERNAME/path/to/flash_image)
IMPORTANT: Turn on USB debugging. Settings -> Applications -> Development -> check the box "USB Debugging"
Open up and adb shell
With your phone booted, type the following command
s:
Code:
adb root
This will start ADB as root, or notify if it is already running as root.
Code:
adb remount
This will mount the system partition (/system) as writable, allowing the following
Code:
adb push flash_image /system/bin
This will send the flash_image script into the /system/bin, so we can use it from within the shell
Code:
adb shell chmod 0755 /system/bin/flash_image
Finally, change the permissions of the script to allow it to perform the desired action.
Now that the script is installed, we are ready to proceed with flashing the custom recovery, saved on the root of the SD card earlier:
Code:
adb shell flash_image recovery /sdcard/recovery.img
P.S. If you want i can post here method by flashing original 1.6 ADP Rom via fastboot (but as i think it is on htc dev web... But i can post here cut version of this - coz original version have many not needed things.)

hey ANtiHazarD i have a desire so im not sure if this is suppose to work but all 3 methods fail for me, any advice, thanks in advance

Nice steps! man hope this gets a good stick or added to the rom bible, you do know though fastboot method is a common way to flash recovery

That's what I was thinking... Seems almost pointless for a guide since there's instructions how to fastboot on every recovery thread.
Either way, nicely written guide. Someone will probably find this useful.

With a desire this is quite different, as it has an activated nand flash protection (s-on), so no fastboot flash recovery here. Although this should prevent you from not having a recovery at all...
* note: I don't have a desire (yet) so this is speculation *
Best is probably something similar to this http://forum.xda-developers.com/showthread.php?t=750852
I guess if you get the correct PB99IMG.zip for exactly your device/brand you will not need a goldcard, so don't follow the howto blindly (it is for the newer SLCD versions, but the basics will still be applicable to AMOLED devices). Best would be a PB99IMG.zip that still has a hboot version < 0.92, otherwise you will need to downgrade to root. If you already have 0.92, then just take the newest image, as older ones are normally not flashable.
After step 7 of the howto, you are either done, or you will need to find instructions to downgrade if you want to root.
As soon as you have a working system, with a 0.8* hboot you can just use unrevoked to root and flash a custom recovery.
Enough OT... @ANtiHazarD: Very useful overview. Thanks.

WAY WAY WAY more complicated than it should be...
It is a simple matter of:
fastboot flash recovery recovery.img

I can get into fastboot bet have the same problem :
writing 'recovery'... INFOsignature checking...

I get into fastboot with thre android logos on skates,
even tried to restore nandroid using fastboot but I get the same error? could you help me out?
I have HTC DREAM with 1.33.0013d and radio 2.22.27.08
I am really frustrated,
I tried all you gave up here but none worked for me.

Also when I try to get into recovery I see a G1 logo with a fastboot usb written on top left in red.

Did you read everything before you flashed the 1.33.0013d SPL?
If yes, you would have noticed, that this SPL is not able to flash a recovery or radio using fastboot. You have to flash the orange-...nbh file to get back a full engineering SPL, but you will loose everything you have installed on the phone ...
Send from my G1 with HTCClay's UNOFFICIAL Superfly 1.6 D/S ADS using XDA App

i don't know about this spl, but all what you can do (what i know) you can use this method which named in prev. post. with RC29 or RC7 stock firmware *.nbh
after flashing all data, radio, recovery will be reflashed by a stock data. All must be fine after this... i hope
ezterry can give for your advanced advice, may be

Don't use RC29.. its once of the most annoying NBH files to need to re-root for the dream.
If you have 1.33.0013d note the orange.nbh posted on the new radio OP post: here
ezterry said:
If you find yourself stuck without recovery!!
Dream
1) Download: orange-1.58.73.2.nbh (MD5: aca4dee0c1ece7e9773f2ecbdfbba7c0) (mirror)
2) enter fastboot and run 'fastboot flash nbh orange-1.58.73.2.nbh'
3) wait for the entire nbh to flash
4) boot into the bootloader again (it will be an engineering SPL 1.42.2000)
5) You can now re-flash the radio/hboot/recovery via fastboot that you wish to have installed.
​
Click to expand...
Click to collapse
basically if you intend to still use the new radio; after installing 1.58.73.2 you can reboot-bootloader; and use my fastboot installation steps at the top of that post
You can do this without a goldcard because I bypass various checks in 1.33.0013d
(It will let you install any other signed NBH but that will still wipe the phone completely; and if it fails to flash cleanly it will leave you without an engineering SPL thus make it harder to make android go again)

hey i tried to flash the MTD too and now i keep getting "E:cant open CACHE:recovery/log" when i go into recovery . I can flash roms but when i reboot my phone my phone stays in the G1 Logo . and when it does make it to the rom i can not get my market or gapps no matter what i do . please help me guys .
EDIT: theres times when i get past the g1 logo but itll just stay on the roms boot screen forever until the phone dies . does anyone have any ideas ?

It's worth learning to use it ...
Really, especially when using the 14MB-hack or CustomMTD and it's not so difficult. There should be a tutorial on adb and fastboot here in the forum.

I am hanging at booting while trying to do this any ideas?

[Q] No recovery

Hello every body and sorry for my poor English !
I have root my phone some month ago by changing my recovery with flashrec 1.0
all work done, I can be root on my phone by press "su".
But there is an update now and I want my old recovery partition.
So I use flashrec and type "restore backup" but it tell me failed !
I restart the phone and try it again : and in 0,01 second flashrec tell me success and when I restart my phone in recovery mode I have a block screen with triangle next to phone icon and I can't do nothing else than remove the battery !
So I try to do :
Code:
adb shell reboot bootloader
fastboot boot recovery-backup-htc-hero.img
But it answered : "FAILED (remote: not allow)"
I try :
Code:
adb shell flash_image recovery /sdcard/recovery-backup-htc-hero.img
But it answered : "mtd: read error at 0x00000000 (Out of memory)"
or nothing happens.
I have try :
Code:
fastboot erase recovery
But it answered : "FAILED (remote: not allow)"
Any idea for recover my recovery ?
Thanks or your answers.

i guess you are using unlocked SPL It might be causing problems

The link is for root a phone ?!? no?
I just want to recover my recovery !
For flash my old recovery I do all it say in your URL apart the format of SD card, do you think it is important?
Moreover memory on my phone is 56m do you think it can be the problem ?
Can I saw my recovery partition on the file system?
Thanks at both of you for your rapid answered, I hope you will answered me again !

Is your phone is rooted ?
Code:
"mtd: read error at 0x00000000 (Out of memory)"
It needs rooted phone to run it ..
i 'd suggest root your phone -)
&
try this :-
Power on your hero while holding down the volume down button.
then:
Code:
fastboot erase recovery
fastboot flash recovery - & filename of recovery in the pc
try flashing old Recovery of Amon_ra first . if it works than try latest one ..
If nothing comes on your way. than i would suggest use stock RUU & than try flashing Amon_Ra & See you can flash it from boot loader or not ?

Yes my phone is rooted : When the phone is on, I can become root by typing "su" and then an application ask me if I allow to become root.
So I have "Power on my hero while holding down the volume down button" and I see a green check list during a second and after I see in blue HBOOT.
So I have try to do on my computer "fastboot erase recovery" but my prompt say me
Code:
C:\Windows\System32>fastboot erase recovery
erasing 'recovery'...
and it never do anythinks !
So if I press back on the Hero I can see :
Code:
C:\Windows\System32>fastboot erase recovery
erasing 'recovery'... FAILED (status read failed (Too many links))
finished. total time: 78.280s
An idea?

I'm totally out of ideas...
you are not using the standard data cable that comes with the htc hero? status read failed (Too many links)) error comes when you are not using standard data cable that comes with the htc hero..
Make sure your adb tools working correctly..

This is the standard cable but a little broken.

Thanks !

your cable is causing problem . find a good cable and do it

I had problems with the original cable. So what's happening when you shutdown and press menu/power. Blocked triangle?
And it was all yellow...

EDIT : when i reach to the ( fastboot flash recovery < recovery ( what ever the name was ).img >
in windows 10 ( error can't load < recovery ( what ever the name was ) >.img
in linux " ubuntu - i'm using zorin based on ubuntu " in terminal ( waiting for device ) and kinda stop there.

but to be fair with you and to thank you :good: and give credit i did indeed did not clarify the last point.

in limux " ubuntu - i'm using zorin based on ubuntu " in terminal ( waiting for device ) and kinda stop there.
so thank for waking me up to clarify things.

First, make sure you did these:
Enable developer mode on phone, enable adb, run
Code:
adb devices
, confirm notification on phone to allow access.
Perhaps you need su permissions...
Restart the phone, hold POWER+VOLUME UP.
Code:
sudo fastboot flash recovery recovery.img
If that doesn't work, what are the results of
Code:
fastboot devices
? What about
Code:
sudo fastboot devices
?

Yotaphone 2 bricked

If you are using Yotaphone Flasher (and I suppose it), the problem will be the "random" stuff in the .firmware folder after you download an image. Unzipp everything to the .firmware folder from the .zip archive file (for example: 5.0.0-EU1.1.124b.zip), and overwrite all files.

My YD206 phone also got bricked while trying to update from RU 124 rooted/twrp/xposed to RU134.
Is there a low level tool like ODIN which i can use to reflash/repartition everything?
i guess some of the partitions are not ok and i can't just use high level tool as adb/fastboot to load the new rom - it gives me error during writing to partitions.

To get my YotaPhone out of the bootloop I followed these steps:
- Put your phone in download mode. Keep holding power and volume down, it will get there eventually.
- Use the YotaFlash tool to flash the latest EU or RU firmware, whichever you like.
- After YotaFlash is finished your phone will reboot and still be in a bootloop
- Put your phone in download mode again. Just keep holding power and volume down.
- Now go into the command prompt on your computer and navigate to the YotaFlash folder (for me it is in C:\Program Files (x86)\yotaphone_flasher)
- Now type the following command with your phone still in download mode: fastboot flash -S 512M system firmware/system.img This will flash the failed system.img in multiple parts.
- After the flashing of the system partition is finished reboot your phone with the command: fastboot reboot
After this your phone will restart. It may take around 10 minutes to finish and if everything went right the Android unlock screen should appear.

Omg, yotaflasher actually flashed it properly now.
Not that i haven't tried it like a million times last few days.
On the first run instead of errors during write it went OK and device restarted showing the Yotaphone boot animation.
Remember don't touch it/reboot it while it shows the boot animation - it actually is doing something.
I suspect that last time i did TWRP flash it was successful just the boot was not OK, and now Yotaflasher restored boot also.
I was almost considering buying another copy from Everbuying.

[TUTORIAL] Unbricking VNS-L21/VNS-L31

Hello everyone! I know there are a lot of threads and comments about unbricking your device but in order to get you on track quicker then anything else and point you to the right direction i`m writing this tutorial which i find is quite successfull. This tutorial was made basically on my personal experience and with the help of some advices and suggestions.
First of all there are some questions that you must ask and answer yourself in order to do everything correct:

GUIDE 2 (When no one can help you but you :silly
First of all you should know that every case is different from one another but everything comes to one mission. Access to fastboot or access to custom recovery in order to unbrick. I will give you steps which I did when I bricked my device and I had no fastboot access, no access to stock or custom recovery, no erecovery access and no wi-fi upgrade.
So what I experienced?
You see logo but only that. Warning screen saying bootloader is unlocked. When you see warning screen u`ve got a choice what to do – Press to enter recovery, press to continue booting etc. None of that. When I was connecting the usb cable to the PC no detection at all. No working key combinations.
1. DRAIN BATTERY! REALLY. IT`S THAT SIMPLE. Leave the device on and put it in a shelf or something like that so you can`t see it and can`t touch it. 2-3-4-5 days. (I left mine for 2 weeks! :laugh The battery must be that empty that when you try to power it up only power icon shows up or nothing shows up at all.
2. When u`ve done with Step 1 get a laptop or a PC with freshly installed Windows or Linux.
3. Install SDK Platform Tools (ABD and FASTBOOT) the newest version from their website!
4. Install HiSuite from their respective website!
5. So now when you`re all done with installing the requisites get your phone in your hands plug the usb cable in the phone and then hold down (VOL -) + POWER when plugging it to the PC or laptop.
6. Believe me. It should get into fastboot. I`m 99% sure. If all the steps I wrote are done correct!
Why should battery be drained at ZERO?
I will tell you the truth – I don`t know. Really. But all I know is that it`s kind of a switch. When something goes wrong draining the battery will clear something that it shouldn’t be there.
If this tutorial helped you then click Thank you so i can count how many good things i`ve done in my life he he! If i didn`t helped you then don`t stop reading until you find the solution! Good luck!
How did you unbricked your device? Tell us here and help others do the same!

Is there a special reason why we should use a Nougat Recovery? I'm on C432B160 and have tried the change filesystem thing with METICULUS Recovery and well... it didn't work

Thank you!
Created an account just to say thanks for this! I've have spent hours and hours trying to unbrick my phone..

Good question! The reason i told everyone to use there version and this custom recovery is because METICULUS is not working at least didn`t for me! It didn`t even started at first place! Nougat is preferable because a lot of people get in trouble when they upgrade to Nougat and then try to downgrade that`s one of the reasons too. So my advice is try Nougat custom recovery for your case! Good Luck and best wishes

Yes of course there will be no trouble at all but instead of METICULUS recovery use the one i posted here! You have access to fastboot and unlocked bootloader so just follow the steps from number 4! If this doesn`t work you can try to flash http://consumer.huawei.com/bg/support/products/downloads/detail/huawei-p9lite-bk.htm?id=93797 this rollback package and via the method with SD Card and then flash stock rom from the link above! :highfive:
Good luck and i`m waiting for the result! :highfive:

Okay. First of all buy a decent Micro SD Card at least 6gb of storage! This is one of the most important things i forgot to tell here. Decent means famous brand like Kingston or Philips or something like that because other then this will fail! After that do you have access to fastboot? If you have fastboot then type "fastboot oem unlock <your unlock code>" If you don`t know it i can help you with that! After that flash the recovery i posted and try to fix the partition by the way i explained above. Then follow the last steps for preparing the SD and flashing the ROM. Good Luck my friend:highfive:

I appreciate the help, but the phone is locked. Phone Locked and FRP lock. I already imagine that at this point I only have a nice paper weight.

Check again i correct it

I´m facing the same poblem. Bootloop with Bootloader locked, FRP locked, battery empty. I can get into fastboot mode but no chance of flashing anything. USB debugging seems to be deactivated. I cant charge the battery because as soon as I connect the phone to a powersource its starts the bootloop. Force flashing via sd card (volume up and down plus power) doesn´t seem to work either (guess due to the low battery).
Any suggestions are much appreciated.
