[Q] Help please - Cannot activate recovery

For some reason my Nexus S will no longer go into recovery mode ... it only restarts the fastboot mode when selected. I'd like to get as fresh a start as I can here, but can't figure out how to get back into recovery mode to get a new image loaded.
I've got the stock-GRH78.zip which seems like the right place to start, but can't figure out how to reload it.
Thanks!

Moved to general

thanks for the move ... hopefully someone will be able to help!

If the bootloader just reloads itself whenever you try to go into recovery, that means that the phone doesn't detect a recovery image. Check the top of your devices as well. In red colors, it should say something about not finding a recovery.
We don't have a true copy of the stock recovery, so you are going to have to use Clockwork Recovery in order to move forward from here. Google has not released the recovery files/rescue .zip so you're going to have to unlock the bootloader/root to fix this. Once you've flashed that on, then you can do a NAND restore of the stock 2.3.1 image linked in the stickied FAQ or in the development section.

will run through this ... thanks. I don't see any mention of not finding a recovery image. Red just says Fastboot Mode and that my lock state is unlocked.

still struggling along here ... in fastboot mode, I can't connect to my device to run commands so fastboot seems pretty impossible. I can connect when the phone is more fully booted, but you can't run (or I can't anyway) the fastboot commands ...

You need to install the drivers for fastboot to recognize the phone. Should be detailed in the link I gave you. If not, try the method below. It's what I used. not entirely sure if it will work for you, however.

I'm on a Mac ... No drivers required as I can tell. It worked pre-root.

Eh, sorry, don't think I can suggest anything else. :/
What worked pre-root? ADB or Fastboot? They're different. Nothing happens when you type in "fastboot devices?" If fastboot doesn't work, I'm pretty sure you're toast. :/

Both commands work but not once I am booted in fastboot mode. Then I lose my connection from the desktop ...
... once rebooted, I am still unable to do anything from fastboot mode. ./adb devices shows nothing listed. added the cable once there, rather than with it connected to switch over. sigh.

I often don't get a connection on the Mac unless I unplug it from USB and re-plug it in after I've entered fastboot.

Yeah thanks I have tried that multiple times as well as used multiple ports and a USB hub. Maybe rebooting my Mac a few times will do something

when I do ./fastboot-mac devices I can actually see something ... that's got to be good! adb shows nothing in fastboot mode.

resolved ...
courtesy of my waking up and of course the guidance here, I was able to sort this out by flashing over a recovery image via fastboot. I then used the GRH78 Nandroid backup to get my S back in order. whew!
thanks everyone!

that is correct, ADB is more for when you are already BOOTed up on the phone
fastboot / fastboot-mac is for when you are in the BOOTloader screen
Just a suggestion, since you have a MAC
it'll be best if you set up a VMware WinXP machine set aside with USB enabled
you'll come across a lot of GUIDEs, HOWTOs and other references written for PC users.
LOL just saying that reminded me of the MAC & PC commercials

Kind of ironic that a linux/unix based phone doesn't have the best support for it on unix based computers like the Mac.
At least fastboot plays nicely with Androids on the Mac. The Galaxy S phones I've had forced me to find an old windows laptop to be able to use Odin.

Help with ROM load

I bricked my xoom trying to fix the uastring. For some reason cw doesnt recognize my sd card so i cant just reflash, ive tried it with a different sdcard so it must be something with cw.. anyway, how should i proceed from this point?

Adb push the old framework-res.apk back to system/framework. If you didn't back it up download a rom extract the file then push it.
Oh and to edit the framework-res.apk i had to replace the res folder and the resources.xx file then it worked.

OK, you unfortunately updated your recovery to the dreaded 4.0.0.x in CWM and it doesn't see your sd card. You need to install a good version of the recovery (specifically 3.2.0.0) that does read it. Are you stuck at the dual core screen, or can you get into any recovery? You sound like you know enough to get out of this jam since you rooted. Now that you know what the problem is, I'm sure you can resolve it. Xooms are actually pretty hard to really brick. I've gotten myself into and out of some very hairy situations.

Thanks for all the help! Unfortunately I'm at my inlaws tonight, when I get back home tomorrow I will use your guidance...... Yes, I am stuck at the dual core screen but I can still get into cwm. Thanks again, I can't wait to get it fixed, I am having to type this on my wife's iPad, yes, it's killing me!

Boot your xoom into fastboot mode manually. To do this hold the volume up and power button until the xoom turns off. As soon as you see the moto logo start tapping the volume down button. in the upper left corner you should get options, choose fastboot. In Fastboot mode try running "fastboot devices" from command promt on PC first to see if the xoom is recognized. If it is, you can be saved. From here try "fastboot oem unlock", you should then see intructions to follow on the xoom screen. If when you reboot you get the same issue, get into fastboot again and flash the original stock moto images. Good luck.

it will not go into options when doing that sequence, goes to that error code. sbf using rsd lite didnt work either....

forget that last post! ok, i got it into "fastboot protocal support" what next?

for some reason, the comand promt in sdk isnt accepting any keys. i have no idea whats going on.....
just a progress update, by using the one click root method i was able to get back into recovery, unfortunately its the 4.0.0.4, but im getting closer. now if i can figure out whats going on the sdk, TE will not take any input

ok,ive gotten sdk sorted out. i have been using this guide (starting at step 4), file on my pc are in the right place but i cannot seem to get the proper cwm flashed. is this the right command, except for the file location? I put the .img file in the root of c:

SHE"S BACK!!! I was having probleams flashing becuse the c: in that command line psoted was in the worng place. once i got flashed back to 3.2 cwm it was a breeze ofcourse.
Thanks for all the help guys, I know its a pain helping a dumb ass,,, thanks again!

Need help. Phone has bad rom, can't access recovery

i may be up a creek now. i've tried everything i can.
here's the whole situation, maybe someone can offer some guidance on how i can get my phone back.
i installed this rom, http://forum.xda-developers.com/showthread.php?t=1835478, but did not see that there was a problem with people getting stuck at the initial google boot logo. i wouldn't have tried it if i did.
but it's too late now. so i too have that problem. in addition, i also have that problem with the nexus s in that the power button is busted, works only to boot the phone.
so i boot the phone normally, i get to that boot logo indefinitely.
i press up and power button i get to fastboot screen. for some reason the volume buttons don't work on that screen so i can't pick recovery there. only thing that works is hitting the power button and reboots the bootloader.
i plug the phone into my pc and i can't access it through adb, fastboot... does not recognize a device is connected.
so in summary, all i can do is access the fastboot screen or the boot logo screen.
if someone can help me figure out how to do one of the following: boot into recovery instead of fastboot, figure out how to use the volume buttons in fastboot, or get the phone recognized by my pc so i can use adb, that would be awesome.
i feel like i just bricked it for good....
thanks

Install the SDK. Launch it. Find the drivers to download in the SDK. Install them. Boot the phone into fastboot and connect it to pc. Open up a command prompt IN the directory that has fastboot in it. Type in the command prompt fastboot devices.
If your serial number shoes your good to go. Get the .img of your custom recovery and type fastboot flash recovery nameofile.img. with that being the exact file name ( hint type the first letter of the recovery and hit tab)

Yep, you gotta get fastboot working again. It's pretty important.

i've had the sdk/driver installed already.
like i said, the phone when it boots is not being recognized by the laptop at all, as if it's not even plugged in. so when i do fastboot devices, nothing shows up.

Was it recognized prior?

in the prior rom it was recognized by the laptop, before i tried to flash the rom i linked above that created this mess...

IT shows flashboot steps, you need to connect phone in bootloader mode which you are achieving atm, and see if it works
and if it doesnt then let me know i will try to help out more if i could
P.S I am also new in android so pardon my noobnes

i went another route...
i figured i had nothing to lose at this point... so i ripped the phone apart and attempted to fix the power button, which i believed in turn would fix not being able to use the volume keys in the fastboot screen.
i was correct. i jiggled with the power button inside and it seemed to work. the volume keys now reacted in the fastboot screen.
i was able to then get into recovery, wipe the phone, connect the phone to the laptop and put a new rom on it.
i'm not sure if its fixed the button completely, but at least i can get into the new rom :laugh:

well thats a relief and i am glad that you problem is solved

Did you do what Jack said and GOOGLE IT????? Go away and put some effort in for yourself - it will be much better for you to understand WHAT and WHY you need to do things - or next time you will brick your phone beyond recovery.

@op cd ( http://en.wikipedia.org/wiki/Cd_(command) ) in the directory where your fastboot and adb in located ( path-to/platform-tools) and fastboot commands should be working.

Oh c'mon guys don't be so rude. You've been noobs too.
To return in topic:
1) you have the clockwork mod recovery, so I'm assuming that you already have unlocked the boot loader but you still S-ON ( you can check it by powering up the phone by pressing TOGETHER the volume down AND the power button). But i may ask you to verify that you have installed on your PC at least ADB and FASTBOOT? If you're not, please install them, otherwise you won't be able to get your phone work.
2) now, you say that you have flashed the pacman ROM but you are stuck on the HTC logo. Don't panic. It is a common issue, i have done it a lot of times. Just check from adb if it can see you device (you have to plug in the phone to the computer via your recharge cable). If it sees the phone it is quite simple to return to the boot loader. Simply open a terminal on your pc, navigate on the folder in which you have saved adb and write "adb reboot bootloader". This will bring you to the bootloader screen. Check now if there is written "FASTBOOT USB". If not and it is written HBOOT USB navigate with the volume keys on fastboot. This should bring you to the fastboot usb.
Now double click on the .zip containing the pacman ROM you've installed. Extract ONLY the boot.img and place it in the same directory in which you've placed fastboot. Now in the terminal of you PC write "fastboot flash boot boot.img" and then reboot the phone. This should solve your issue.
If the adb doesn't see you phone you have to pull out the battery, WAIT at least 30 seconds, replace it, and then press TOGETHER volume down and power button to enter into bootloader. From there follow the step that i wrote you previously and you'll be good to go!

^^^^ This ^^^^ There is a HUGE difference between helping someone when they need help and helping someone when they are just being too lazy to actually read and find things out themselves.
I see it as no different to when I need tech-support from one of my equipment suppliers. If I call them up with a genuine problem they will help me, but if I phone them and say "Where do I plug the keys in?" or "I've turned the kit on but didn't bother reading the instructions first, now it's broken" - what do you think their reply to me will be?

Yeah, you're right. But from the disperation of the guy It seemed to me pointless to leave him with a non-functioning phone without any advise. After all this is a forum plenty of people that know how to do practically everything with an android device, but I don't think that everyone have started from a solid programming base or a perfect hardware knowledge.
Regarding me, I have looked into this forum a couple of months BEFORE even try to unlock my phone and flashing something other than the horrible desire's gingerbread stock rom, but I understand the people who wants to try something new, even if they are not so expert.
For the next time, don't worry I'll be mercyless

I'm always ready to help where i can but. It seems like the op followed half a guide then just assumed it would work, i must of read all the guides until my head hurt, and most of my first posts were silly questions already posted. I learnt far more about my phone from searching than i think i could have from my first posts

OP7 Pro Fastboot Bootloop! [HELP]

This may be a simple solution, but I am completely puzzled on how to fix this.
SO i recently rooted my phone & used the twrp "twrp-3.3.1-4-guacamole". Installed magisk via that twrp and continued with my day.
I accidentally got a virus by trying to get a full free vpn, me being a terrible pirate, i accidentally got a virus! Silly me.
It was annoying me and I decided to factory reset my phone... not via twrp. I remembered after I clicked "Reset all" on oxygenos that it's not the way how to do it with a root device, and well.. it didn't exactly work.
Every time I power/reboot the phone it just brings me to the fastboot menu of "START", "POWER OFF", "RECOVERY MODE", & "RESTART BOOT LOADER". I thought since TWP is recovery mode I try to access that... no luck, it just brings me back to that fastboot menu. I tried going on CMD via adb by saying "fastboot flash boot twrp-3.3.1-4-guacamole.img". It will say it's finished and successful, but when i reboot and try to access recovery mode it just does not work.
TL;DR: Think I bricked my phone, there is no OS installed and I can only access the fastboot.
Any help? Much appreciated

Thank you for the guap recovery as i didn't know it existed. However, what are the steps? when i go on the MSM download tool it doesn't detect my phone.
that being said, i can't access any of my files through my pc using fast boot. on MSM it's just saying "waiting for device" even when plugged in so thats annoying.

Whenever I try to install the qualcomm drivers it never shows up, and when i try and boot it up so the gual recover detects my phone it never works. It's still saying "waiting for device".
Does anyone know how to fix this? it's doing my head in that it's not as easy as it should be.

Pretty sure that your phone will not be accessible via adb/fastboot during the msm process. Did you follow the directions in the link above to a T?
A few things to note:
- Works perfectly fine for unbricking GM1917 modeled OnePlus 7 Pros.
- Use the original cable and try to plug it into a USB 2.0 port. I've found that this is the most ideal condition.
- Make sure your device is charged up. If you can't see how much charge it has, leave it charged via the 30W warp charger for 40 minutes and that should be good enough.
- In the L2 drivers folder found in the archive, navigate to the 32 or 64 folder depending on your system's architecture, and click on the file that ends in the extension ".cat". Then, click "view signature", then "View certificate", then "Install." This is IMPORTANT.
- Then, make sure your device is powered OFF, then, plug in the USB-A side of the cable (big head) into your computer and do NOT connect the USB-C (small head) into your phone yet.
- Hold down Volume up AND volume down for five seconds, and while you're continuing to hold, plug the USB-C side into your phone. The drivers should automatically download, and you should see a "Qualcomm QD loader" device in Device Manager. If you see an exclamation mark or you don't see this, you are doing it wrong and you need to repeat the above steps.
- Open up MSMTool.exe as an administrator and click 'start' only. Should take a few minutes, but you will have a good-as-new OnePlus 7 Pro.

Pretty sure that your phone will not be accessible via adb/fastboot during the msm process. Did you follow the directions in the link above to a T?

I did yes, i pressed all buttons and the power button for 5 seconds and plugged my charger in. Then after that went on the MSM tool and it went straight to the fastboot. I really don't know but it loves this fastboot tool haha

It's one of those things where if someone was there with you, it'd likely get figured out. I've seen this kind of situation hundreds of times on XDA, and with all due respect, the problem is most always at the hands of the user. These phones are cookie cutter made, so there's nothing different (besides individual variants) that would make thee tools not function correctly, unless it's operator error. But that's not set in stone. Just don't give up. Try setting up your camera for an overhead view. I couldn't tell if you were plugging in your cord. And it seemed to reboot, instead of power off. Repeat the steps carefully, and see if you can achieve better results.
Don't give up! We're here for you ?

Make sure phone is powered off before plugging it in. Launch msm tool, Press the vol up and down key for a few seconds then plug in.
Edit : make sure your drivers are up to date too.

I don't know about msm tools never tried it but I know your situation.
Don't do fastboot flash boot twrp-3.3.1-4-guacamole.img
Remove the word flash. You are supposed to boot into twrp then flash the zip file to the phone.
look at this

Command in Fastboot mode is:
Fastboot boot "name of the recovery".img. Phone should boot to twrp. Then flash twrp.zip
or try Fastboot roms:

Choose the one for youre phone (region)
MSM tool it's the last option.

Can't you just switch slots from fastboot or did you mess up both?

Firstly I'm terribly sorry for no response (same goes to everyone else looking into this matter for me. THANK YOU!)
However, I have done this multiple times in the past and it instantly goes back to boot menu. it sucks :/

If i'm honest with you.. i'm not sure in the slightest. My only assumption is no because the only thing I can access is only the fastboot. if i attempt to go into recovery mode it will go back to fastboot. when I flash twrp it will flash but it won't boot into it. It's confusing as hell.
Just to add to this whole situation:
Since I have no idea and just wanted it fixed in the day; i was willingly to give money for this phone to be fixed, but thanks to the person, he just made it a slower process by doing things i've already done.. going to pick the phone back up in an hour of this message.
I haven't used the fastboot boot twrp cmd yet, but from how everything else has been so far i feel like that won't work, but i will update everyone on that situation.
Just to add additional things that I may have not mentioned in the past will be below:
- Whenever i type in "ADB Devices" in cmd, it will not show up with anything. However, when I type in "fastboot devices" it shows it's serial and in "fastboot". It will only show as fastboot and i can't access the phone via file explorer in windows.
When i say "ADB Devices" it says *devices attached* and will show none of my phones details, but when i say fastboot devices it will then show the devices.
^ what i said above means I can't use the guap recover, or anything which means the phone has to be detected in windows, because other than fastboot, it won't work at all.
- So far I can't access twrp as a whole, so if anyone knows how to give me a guide on how to install it from where I am at, that would be amazing (if not, i'll try and reiterate what to do with the one given from a previous comment, so thank you )
- There was one time I was allowed in TWRP but i completely forgot how i entered it (so i can't explain), So i feel like there is hope in that aspect. I feel like i entered something via cmd so maybe there's a way?
In terms of hardware my phone is completely fine, there's not a single problem other than the software being a pain in the ***!!
if anyone can just spew out a bunch of help in different explanations it means the world because so far all I can see is that I wasted about £600 on an amazing phone because of dumb *** haha.
Thank you to everyone who has helped, and is helping

From your comments, you are not familiar with how Android functions. Not knowing the difference between adb and fastboot is an indicator that you should just endeavour to have a stock phone until you understand whats going one. It's also hard for people to help as no one has hands on and can see what is broken. Everyone here will be working blind like trying to fix your car for you from across the country.
Start the phone into fastboot and connect it to a pc. From a pc command prompt in your fastboot directory enter the command:
fastboot getvar current-slot
If the current slot is A then:
fastboot --set_active=b
or vice versa
fastboot --set_active=a
then fastboot reboot and see if you boot into the other slot.
Not knowing what phone you have makes it even tougher but I suspect you will have to reflash a clean complete rom via fastboot.

I do appreciate the help. If i'm honest with you the only reason I did this is to increase my data speeds (which from look of things is outdated now), and a longer battery life. I don't know much about rooting/jailbreaking but believe me that I have been in the scene for years, but not even knowing everything haha!
that being said.. i'm in twrp! thank you so much mate, i'll try and go and install the rom now. thank you!

Now install the zip twrp

Thankfully.. IT'S FIXED!
I didn't have to install twrp again or any of that. I simply changed the slot from A to B and pressed all buttons when it was showing the "! Your decide is unlocked" orange/black screen.
I had msm tools up and it detected and instantly installed the OS to the latest one and boom. It works again!
I got to thank everyone for helping me because without you people I wouldn't of been able to fix it. I looked everywhere and no help anywhere as I feel like it's pretty dumb to do what I did haha!
Thank you again people!

Oh you gave up on root?
You are supposed to read the instructions and follow them to the letter. When I read your post I realized you tried to install twrp like you would pre Oreo but it changed you have to boot into twrp then install it via zip file.
Anyways just remember that for next time.
