Nexus One won't boot into Recovery Mode - Android Software/Hacking General [Developers Only]

Hi, if anyone saw my other thread earlier you will know how I've got this far but its not too important. Anyway I've just flashed a custom recovery img (Amon RA) to my Nexus One and now i can't boot into recovery at all.
I get to the screen with the x and the padlock and then the screen goes blank and nothing works. If you saw my earlier thread you will know that this is also what happens when I try to normally boot up my N1 at the moment too but I need to be able to access recovery to flash a new rom and fix this.
Any ideas people? Alternatively is it possible to flash a ROM without accessing recovery?

Nevermind I've fixed it. Always thought I had the AMOLED N1 turns out I have SLCD. Quite a disappointment but atleast I should be able to get my phone working again.

Where is the original recovery image ???

Could anyone help me out, I have been searching for about 2 hours all over to get the original recovery image back on a friend Nexus S, he had issues with CyanogenMod and now want to be back to stock.
I have tried my best to get him to rethink this but, nothing to do. I have so far followed the procedure found here and everything went perfectly until I tried to reboot into recovery.
Now not only cant I get into original recovery but, I cannot even get the clockwork recovery. Instead, I get a android robot with a yellow triangle and exclamation mark.
I could re-install clockwork recovery with fastboot but nope, he wants the original one.
Can anyone help me to find it
EDIT: The supposed to be original recovery image I have gives me:
Exceed blocks 0x000000020 > 0x00000001e
even after a Flashboot erase recovery

Relax friend, you did better than you thought!
The android with the exclamation point IS the stock recovery. When you see it, hold power and press volume up to reveal the user interface.
For future reference, flashing a stock ROM will typically install the stock recovery as well.
Cheers!
Yup thanx

That's why I don't root other people's phones. Just don't like the feeling when something doesn't go right. Or always having to fix their problems. It's just a matter of time before they become curious and check it out for themselves.

[Q] Recovery issue

I rooted my phone using the one click and installed the rom the ICS. Now when i went back to update my rom and when it loaded to the recovery screen, i selected the recovery but nothing happens after that it just reboots and comes back to the main menu screen. Help pleaseee
This bug has been acknowledged in many other parts of the forum. The bootloader seems to be made for SAMOLED screens and the backlight doesnt turn on with i9023's (the SC LCDs), which is what you would have.
Going into fastboot (Vol. UP + Power) and flashing a new recovery will sort it out. I'd recommend ClockWorkMod v5, the latest.
How do i do that? Sorry im kind of new to this...
You can install ROM manager from the market and flash the current recovery as well. It will ask you to the first time you run it.
Ohhh i tried that already and it still doesnt work :/

[Q] strange Rom flashing problem

Hi there, phone screen remains black and no visuals after flashing rom, so I canrt see anything on screen or know what to do about it, pls help?
Details -
After flashing ROM from SD card via which seem to go well... ONLY that the screen is blanked out, no lights except the key lights, phone comes on, responds to touch by giving normal sounds like when I use flick the scroll lock and touch the screen etc (just because I know how the phone works) but problem remains that I cant see anything, so I cant even boot into recovery or download mode to flash again since its all black and dimly lit.
I have a B63M running Gingerbread 2.3.5 so I am not sure what model of HTC it falls under in case this question or similar has been asked already.
I was able to initially get into flash recovery using the mobile uncle tool which allowed me get into recovery, something that has been impossible using the stock recovery in b63m.
I backed up the ROM , cleared cache and daikvil cache then went on to flash ROM using an update.zip and then the touble I explained above.
This is a current situation pls I need help getting back up and flashing the right lattest rom for my phone?
Help me pls

Thanks for your response, yes I have gone the adb route and I was able to see my device in adb but once I say adb reboot recovery or adb reboot download, it restarts and reboots but again I cant see the screen so I have no idea what to do next or what really is happening on screen.
Maybe if you know how to proceed once in adb, you can share with me, this is frustrating me?

More B63M users here?

Hi all, I just ordered a Chinese B63M phone at cect-shop.
Nice phone with great specs.
I alreadu know how to root it, but are there already custom Roms available?
Could'nt find a lot of info, just a Russion version.
B63M... thats my phone

Now that makes us 2 people who owns a B63M and got it from cect-shop.
What I find out about their phones is that it may not easily allow you to perform some insider operations, for instance, maybe its me but I could not find any custom recovery installed and this led to my first issue after I rooted, and installed the ROM manager, I saw the 'fix permission' and clicked it hoping to resolve my force close issues and it asked me to reboot after performing the process but it never got out of the boot, the loop continued, trying to boot into recovery become impossible but somehow a combination got me into a mode where I was able to clear flash and this took me back to a pre factory flash good thing I backed up titanium so I cld restore my apps and upgrade.
Right now I have tried to flash and the screen has gone blank yet the phone is responding to touch as I can hear sounds when the screen is clicked, indicating that its not bricked I just cant see anything going on (this is my current situation and seriously looking for help).
Lastly, I am trying to find out the htc equivalent to this b63m, it looks htc but I cant be sure which of the htc has been more or less cloned... this is going to help with a lot of things if known.
Cheers
Hi there,
If you are looking for a custom recovery, try this forum, altough you have to translate it because it is in German.
Lots of people there with our phone end they know how to get a custom recovery on it.
Cect is German

Yeah thanks, I have also stumbled on the site forum before but I cld not get something out of it, maybe I have not taken time enough to search, I am back on it now and hope I get a solution to the blacked out screen problems I have after flashing.
You know cect-shop is German, they are a German company in China... I am talking to them on skype and hoping they can help me out but they seem pretty busy or cant be bothered because their response is so much delayed or even not at all.
Well technoforum has a special B63M section with all tools required.
They also have nice custom roms like a Cyanogen fork.
I also don't speak Italian, but with the help of Google translate I'm getting pretty far.
But I do let Google translate from Italian to English, that gives me the best result.
Good luck!!
Do you also get no working screen after a reboot with both volume + and power button?
That should get you to the recovery screen without any ROM drivers.
Very correct, no screen even in recovery
When I do the button combination, I believe that it may have responded to my combination for recovery mode but I just cant see anything on the screen, it just remains the same way it was... maybe it graphics issue, as in is the graphics is messed up for some reason or resolution issue, you wont see anything being displayed.
I am just guessing here but all I did was to simply flash an update.zip from sd card.
That is very strange, since flashing a rom does not affect the screen of the recovery boot.
The rom video driver gets only active during the boot process of the rom.
In the past I had some boot problems with my Wildfire start-up that I solved by removing the SIM card and SD card, removed the battery for some minutes and them booted completely resetted.
You could try that, if that does not solve the problem, the only way to wipe the phone back to factory-reset is doing it blind.
After I get my phone I could make a step-by-step guide so you could get to the reset menu...
Another possibility is to re-flash a fresh recovery img to the phone. Since I don't know what was in your update.zip, you could messed up the recovery menue, or even the bootloader.
Re-flashing those could also help and you don. t need the display from the phone, since you use the PC for that.
Here it is
Here is the update.zip I flashed. http://chinamobiles.org/downloads.php?do=file&id=618&langid=4
I am a bit surprised myself that the screen is blanked out but the phone seem to be working still.
I have removed both SIMS and SD card plus battery several times etc. nothing changed.
You said ''After I get my phone I could make a step-by-step guide so you could get to the reset menu...'', I hope you get your phone soon tho, and i can see the step-by-step guide you made.
I have actually flashed recovery into it using flash tool, ODIN dont seem to see the phone (at least the yellow box saying COm4 or 5 is not showing), I can see the phone using adb but when I say adb reboot download or recovery, something happens but I cant see what it is.
I too have a B63M...!!! Spice Mi-350n...........
If you need a moded recovery, i can port it for you........but you need to follow some instructions...i'll give them tomorrow!!
Waiting on you... I hope my blank screen gets sorted.

Ahh thanks man... Ii will wait to hear from you tomorrow, I aim in UK and depending on what time zones you are in but I hope to find you online to connect again.
I hope you have understood my particular issue here tho, the screen if blank even tho the fone seem to be alive and it follows the boot sequence, I can even find it using 'adb devices' command, it just the screen gone blank.
Someone suggested it may be the boot.img but I dont know about that.
Cheers
I'm from India - Local time here is GMT+5:30......!!
So, here you go !!
B63M= MTK6573 + 650mhz + Android 2.3
So, one modded recovery.img can't be used for every B63M.......this is because a different B63M phone will have a different recovery.img..........(hope u understand)
Backing up everything:
1) ROOT is necessary. It is recommended to put the phone in 'Airplane mode' so that it won't disturb the process and make sure you have ~500 mb space in SD card.
2) Download 'BackUpTools.rar' from HERE and extract it to your SD Card. You'll have 2 folders - 'gscript' and 'Install'.
3) Install 'GScriptLite.apk' from gscript folder.
3) After installation, open the 'GScriptLite' application -> Menu -> Add Script.
4) Tick 'Needs SU ?'
5) Click 'Load File' and select 'Back23.sh' and then select 'save'
6) Now Click on 'Back 23' and Super User will ask for Permission and allow it. Nothing more to touch. Wait for few minutes. After few mins, it will say 'Auto Close is Cancelled'. Now its safe to close.
7) Your Back-Up will be in 'backup_' folder located in your SD card's root.
It will have files named ' firmware.info, preloader.img, nvram.img, seccnfg.img, uboot.img, boot.img, recovery.img, secstatic. img, misc.img, logo.img, expdb.img, cache.img, system.img, data.img' in that folder. Copy it to your computer and keep it at a safe place. More Over if you are posting in the forums or sharing it online, don't include ' data.img, cache.img and nvram.img' as they contain your personal information.
Here i need two files.One is recovery.img and the other is firmware.info.
If you give both, i can port one for your phone !! Also mention your phone's model name/number because, without that it is not possible.

That was the problem, you flashed only the update, not a complete Rom.
I suggest you make a complete re-flash vorm scratch, so refash a fresh recovery.img and re-flash als a new Rom.
You can vind one at technoforum' as earlier mentioned
I thot you shd read my latest.
Ok guys I appreciate this a lot.
Here at this point I think you shd hear my developments before taking any further actions or suggestions.
aha thanks, I did just that and it worked although it is still blank at the beginning of boot but later something shows up on screen and completes boots.
Remember I mentioned that someone suggested it might be a boot.img problem... well, I used flashtool to flash a boot image and I can say it worked, I now have the visuals, even tho the screen is still blank at boot start but soon after it picks up and its working, now I have the phone again.
so @balamu96m, my issue was basically the screen, without seeing anything I cannot follow the back up suggestion you gave me here, but now I can see it again.
A couple of additional issues tho...
1- I checked the kernel and it has changed from 2.3.5 into 2.3.4 and >In the current ROM flash I have lost a couple of capabilities like Flashlight, camera etc
2- I followed this link http://www.technoforum.it/forum/viewtopic.php?f=73&t=3351 to flash recovery and it says Successful with the green Circle -OK-... but I still cant get boot into recovery either when I use the keys combi or when I try to boot into recovery in mobileuncle tools, it just goes blank and stays like so until I have to remove the battery and restart boot normally.
3- From the same link above they have the Golight ROM in part 2 after recovery in part 1, I am assuming this a good ROM to flash and the things I lost will get back, but I still cant boot into recovery.
Coming back to the response from balamu96m... Should I still go ahead with what yu suggested and provide you the files details you want? both recovery.img and firmware.info... I am asking because I no longer have the original ROM that came with the phone and like I said I cant even get into Recovery after I tried flashing a new recovery.img, this one from the same link above (see the recovery.img inside the 'Recovery Moddata' file from the 'UPDATEB63MRecovery2012' download file.)
Great to hear that you have visual again!
You still have root yes?
The golight rom from technoforum is a good one.
I expect mine any moment now so I can customize mine too.
Good luck!

You flashed a recovery, but that is not working ah?? Oh God!!
Why did you do that bro??
Do you have any backup of the stock one??
If you dont have, then i have 2 ideas....one idea is to flash something else such that your fone won't boot....now you can send your phone back to the manufacturer and ask them to reflash everything!!!
The other idea, i'll tell you after sometime!!
It was always so

The reason i flashed recovery initially was that my phone went into a boot loop and I was unable to get into recovery, after a while somehow i figure it out and cleared flash and then restored my phone apps and co and got on fine.
But if I could not get into recovery it means that there was not stock recovery on my phone or it got missing somehow. This I have to ask Henkdrenth since he is getting the same phone from the same shop too, but there was no recovery in my B63m, I already heard there is a recovery problem with the phone anyway, and thats why I flashed recovery and it worked but then I flashed ROM and the screen went blank, which is what got me to this forum.
I did not just go and flash recovery, it because there was none on the phone in my opinion.

After many troubles, I found a mod for w690 which is the build version of my phone, I could not boot to recovery so used flashtool and when I load the scatter text of the one I found, it automatically load in every item on the list including recovery and boot img , etc, so I flashed these to my phone... and for the first time I was back in how the phone came to me,
Gingerbread has now returned to 2.3.5.
One thing I have noticed is that the phone freezes on me and then reboots?
I still cannot boot into recovery, I tried this again using mobileuncle tools...
It seem that I have flashed my phone which is good, but I was unable to wipe cache because I could not boot into recovery to do this which may be the source of the current freeze and reboot.
Can I solve this using the mobileuncle or what can I do to wipe cache, if that is the problem
Well, received mine, rooted it an flashed a new recovery from technoforum using myuncletools.
All went well, so I suggest you do also a fres re-flash with a proper recovery.
Hope that should solve your problem.
Edit: moved from my tablet to my PC to look for the link of a correct recoveryfile for you.
First, load this recovery.
Unpack it and put the content to the root of your SD card.
Use myuncletools to flash this recovery.
Now you should have a usable custom recovery that allows you to factory-reset and wipe your phone
Install a fresh rom
How to? Look here

Recovery Help

So I've gotten back an old TF300t that I had originally rooted and rommed and all that good stuff long ago before handing it over to someone else and I'm not sure what exactly was done in the meantime but I can't seem to get the recovery to work now. It boots into recovery but the screen is split into two halves one on top of each other and it does not recognize any touch input, the screen also flashes off every few seconds. It is on the 4.2 boot loader and It appears to be some version of TWRP installed currently but any attempts to install another recovery do not seem to do anything(I've tried clockwork, newer TWRP and a "Kang" TWRP that was recommended in the most popular rom). I haven't seen anything like this before but I don't have much experience with ASUS stuff and my current phone is a super locked down Verizon S5 so I'm quite a bit out of practice.
Does anyone have any thoughts on how I might fix this odd issue? Or even what the cause is for that matter. The tablet works fine otherwise though being stuck on the kit kat rom is kind of annoying. A solution that can be done from the tablet alone would be ideal as the USB cable seems to have gone bad and I only have a wall charger on hand but I can get a replacement cable if this is fixable.
EDIT: NEVERMIND...after manually loading another TWRP recovery I was able to fix the issue and now have a 6.0.1 rom running from that, when I tried to install the Kang recovery I got the same thing with the split screens though not sure what I must be doing wrong. A mod can delete this thread if they wish.
