An alternative to three button combo recovery

I don't know where I found these files, probably in a thread hidden away on XDA but looked again and had no luck!
Basically, the attached zip file, unzip the files. Plug in SGS with USB debugging on and open the recovery batch file.
The phone automatically goes into recovery.
Useful if anyone is struggling with the three button combo!

ADB reboot method does not help the phone when it fails to start properly.

I couldn't find the rooting guide! If you do, please credit that thread and poster with this but this is useful for people in a separate thread. I've used it numerous times!
It's certainly no good for a crashed/bricked phone but is useful for just testing new firmwares, rooting, lagfixing, etc.

That's not entirely helpful, the reason why the 3 button modes are needed is if your phone cannot be reached by the SDK.

I've used it several times just to reboot into recovery to flash a firmware rather than the hassle of taking battery out because three button combo didn't work.
You don't have to like it or use it but if it was useful to me then even if there's ONE other person who this is useful to, then great.
Considering a guy takes his time to make a post to try and help, maybe it'd be better if you didn't just slate it because it wasn't useful to you?

Just downloaded the file, all it does is use adb.exe from a batch file. It's not something new and I'm pretty sure it's been posted before. This is only useful if your phone is booting into a functioning OS state.
You are right that for phones without working 3 button modes, it's how you would get into recovery.

Sorry man, but the guys are right. It is against XDA rules to repost threads. As well, this should be in the General Section to begin with as it isn't directly related to Rom-Development.
Please see the new sticky about forum structure...

Thread moved to general section, and closed as it is redundant.

Trying to root - problems [SOLVED]

Hey guys.
I've been attempting this all morning and so far I've had no luck. I have a VodafoneAU Legend which I updated to the official 2.2 yesterday. But now I want to try root.
I've been trying to follow the HBOOT 1.01 guide but there's a few problems. First, I cannot connect to the phone with adb unless it's in htc sync mode. No other mode will work. So when it's time to copy testimage.zip to the card I have to change from sync mode to disk mode, whereby adb loses it's connection. What do I do about this? Is it a driver problem (in Win7 here) or something else?
Thanks,
Dave.

Ok, the first problem were drivers.
Now I can't finish the second guide. When I try using clockwork to install the firmware.zip, the phone just boots to the red triangle. What do I have to do?
Dave.

So I pressed the up button/power combo at the red triangle and get the Android system recovery. Selecting "apply update.zip" says it can't verify. What do I do? Is this guide for my phone or do I need to follow something else?

I don't understand this guys. Anyone help? I'm thinking since this is a step to root the phone, I'm not actually rooted yet so I can't use the clockworkmod? Then what is the guide for? The guides at unlockr don't mention what firmware/hboot they work for so I'm not keen to try them yet.

Read the guide on fake flash. You need the recovery file named "update.zip" in the root of your sd to proceed..

But isn't that what Rom Manager does? Download the update.zip then run it? Man this is getting even harder to understand.
Edit: And this is left out of the HBOOT 1.01 guide because.....????? When I work this out I'll write a PROPPER guide, lol.

Just checked and update.zip is on the card.
So which part of the guide am I getting wrong?

Decided to reinstall phone with the official froyo release and am now ready to try this again. Is there anyone that will walk me through the process? I will write a complete guide if the "gotchas" are still there.

i feel for you ... hope you get it fixed... thats one of the reason i havent dared messing with the phone because i've seen a few post like yours where something didnt go quite as described... for whatever reason... and im sure the answer is out there but just not within the guide instructions... i guess there is no way to gather all gotchas because there are so many environment variables...
good luck
and please share your technique

Just saw gobczak's thread in the developer forum having similar troubles with Vodafone UK phone, getting the red triangle at reboot. I'll keep an eye on his thread and see how he goes with it.

Did you run the stage1 and stage2 bats while in recovery?

No because the guide didn't say to.
The thing is it seems I'm only stuck on the part where the firmware.zip file has to be flashed. The guide says to use clockworkmod for this. But when I try installing the clockworkmod recovery it gives some file verification error. Isn't there ways to do this via the pc, either through those batch files, adb etc? Or will that fake-flash update.zip file work?

As I just posted on the other forum, I think you need to skip that step in guide 2 and go straight onto guide 3 after you have flashed the LEGEIMG.zip, rebooted, and then removed LEGEIMG.zip from the SD card.

Guys I've got to the point of downgrading to 1.31. But when I run the first batch file it just hangs at the "Writing zip" part, with the htc logo on the screen. Is there any way to fix this?

Can someone please explain this part of the guide:
Phone will reboot and find LEGEIMG.zip on your sdcard, copy it into RAM and check it. If you get CID error at this point, then you don't have goldcard.
Click to expand...
Click to collapse
Ok, so I don't get an error. I get nothing. The phone just boots to the fastboot screen. If I press the power button it goes to the hboot screen and I can see the messages of loading LEGEIMG.zip. But the guide doesn't say to press anything.
So should I or shouldn't I press the power button? Also, if I try making the goldcard again, at which point in the guide do I start from again? The entire process or just copying LEGEIMG.zip to card then rebooting phone? I mean, will all the other things like flashing misc1-2.img still be there?

Guys I finally got this working.
The first problem was with the goldcards. For whatever reason formatting them with the win7 format tool just wouldn't work. I had to use the command-line format tool, setting the block size etc manually.
The second problem was the unnecessary steps in the guide. A few people helped me out with this (namely blackbart at the Aus Whirlpool forum), but basically in the second step you can stop after flashing the LEGEIMG.zip. The updating froyo part isn't needed - for my phone anyway.
Then when running the batch files in the third part, for whatever reason the first batch would keep hanging at 'writing zip...' and I needed to remove the battery to unfreeze the phone. flannigan, also from the Aus Whirlpool forums suggested to just go on to the second batch file. This worked!
So my Legend is now finally a true Legend
Anyway, thanks for the help everyone - couldn't have done this by myself.
Dave

Great news, I think we need a new guide focused on rooting for HBOOT 1.01 / Stock Froyo to clear up the inconsistencies in the existing one. It's a minefield for a noob (or a rite of passage!), a revised guide will certainly save a lot of time and frustration for those taking this road in the future.

I'll write one if ya's want. I wanted to include little tidbits like downloading the apps required (visionary, rom manager etc) from the market then backing them up to the card with Astro so if it goes all wrong and you have to start again, you can just install them all from the card Also on using adb to push the files (roms, img's etc) when the guides say "copy this blah blah". Much quicker than changing to disk mode and back. Sound good?

Sounds good! Happy to help and add my 20c worth along the way. The existing guide has got the meaty bits, a new guide would cull the stuff not relevant, help fill in the gaps and alert to the pitfalls we've fallen into.

I agree... i've done my reading since june of last year but then didnt check for another 4 months... and so many how to's pop up with various ways of doing it depeding on the situation... a lot of those howtos were consolidated howtos which sometimes make intermediate steps unenecessary (may be in some cases causes more head aches since it didnt take into considerations on newer version of hboots...etc)... an updated how to will be much appreciated...
And you're right the most important pre requirement is to have a safety net ... so starting with how to create a back up in case you screw it up is a must!
but im glad it worked out for you!

[FLASHING ROMS] HTC EVO 4G 2.3 gingerbread how to flash roms

Hello again, everyone. This is going to be another one of my easy-to-understand, simplistic type tutorials. For all of the people that might not have an extensive knowledge of android and how to operate basic linux devices, this is going to be a noob level how-to on flashing roms. Most of these directions also go for kernels (not 100% of the time, but most), so just ask if you need help.
Alright, I'm going to assume that you're already rooted and have s-off, as well as a custom recovery menu, if not this tutorial will mean nothing to you. Go read my root tutorial if you need to accomplish this task.
My root tutorial: http://forum.xda-developers.com/showthread.php?t=1228566
How to flash roms:
(Step 1) Finding a rom. May sound easy, but you have to figure out what you want, and more importantly, what you need. There is a very diverse selection of roms here on xda so reading up shouldn't be too much homework for y'all. If you're not willing to do this little amount of work to just read and see what you want and need, then you are hopeless in the first place. I will, however, help you if you are putting a significant amount of effort into this process.
(Step 2) Downloading the rom. This is not hard at all. I get all of my roms and kernels (not including my own) from xda, and downloading has always been a breeze. I can't remember now if you need to sign up for xda or not in order to access downloading. If so, then you should sign up anyway, xda is great! The easiest way to download roms is to download them on the computer then plug your phone in as usb drive and just place them on the root of you sdcard. There is another way though, and it isn't much more difficult. Just go to the market and download the xda app, you don't need the premium (unless you want it) the free version is good enough. The app is pretty much just a mobile translation of the actual site, so finding something on the app that you found on the computer isn't too much of a pain. Once you have found it in the app, just download it, and it should be placed in the folder sdcard>downloads.
(Step 3) Making a backup. Go into recovery by powering down the phone and holding volume down and the power button until the hboot menu appears. Make sure before you actually power down the phone, that you have fastboot turned off. If it is on, then the phone will automatically do the fastboot procedure, instead of going to the hboot menu. How to turn off fast boot: home>menu>settings>applications>fastboot. Make sure that it is unchecked. Okay, at this point we are at the hboot menu. It may check for an image, but shouldn't find one. Just let it do its thing. Volume down to recovery and select it by hitting power. The phone should reboot into recovery. This next part may have some variation because there are a couple of different custom recoveries. Most of them are all going to operate the same though. Once you are in recovery, volume down to "backup/restore". Select it. ALWAYS MAKE A BACKUP BEFORE FLASHING ANYTHING, I AM NOT RESPONSIBLE FOR ANYTHING THAT GOES WRONG!! Now select "backup". It will start backing everything up. It usually takes about five minutes so be patient, if it looks like it froze then just wait it is probably just rendering. After it has completed go back to the previous menu and proceed to the next step.
(Step 4) Flashing the rom. To do this, have the phone in recovery and volume down to "install zip from sdcard". Select this then volume down to and select "choose zip from sdcard". Now navigate to where you put the file and select it. If you did the method of downloading it on the computer then putting it on the root of the sdcard, then it should be on the current menu. If you downloaded it using the method of the app, then it should be in a folder called "download/". Finding it is really simple, just navigate the folders until you see it. Once you have found it, select it and install it. This process might take a couple of minutes. Once it has completed, you can select the reboot phone option and power that baby up.
(Step 5) Troubleshooting. If you are in a bootloop, (a bootloop is when the phone is stuck booting up) then just take the battery out, put it back in and power it up to try again. If it fails again, then go back into recovery. (like we did before^) This is the reason we made a backup. Just volume down to "backup/restore" select restore and select the image you would like to restore. Again, this may take a few minutes, just let the phone work. After it is done you can just boot it up and it is like you never did anything. If this happens, then this whole process was a fail. But, on the bright side, you made the backup (hopefully) and avoided having to flash a stock RUU or bricking your phone. Just try again with more roms, you'll get the hang of it.
Here is a very good aosp rom that I, in know way, take credit for: http://forum.xda-developers.com/showthread.php?t=1178834&highlight=omgb
This rom was created by user: r2DoesInc
I am in no way affiliated with this user and have no right over his/her rom.
Remember, the rom page will probably have directions also. If it calls for specifics, then make sure to carry out those specifics!
Congratulations, you now know how to flash roms, even if you are a noob!
Thank you so much xda for making this site where fellow androdians can come together and help one another.
Thank you to all my supporters and I hope you all found this tutorial to be quite resourceful.

Post all of your questions and statements here. If I don't immediately respond that means I am asleep, at school, or at work. Yes, I am just a high school student, but that in now way makes me any less eligible of being a genius than anyone else.

soo pumped
finally got my evo 4g root tried miui thought it was incredible...until i tried cm7 rc1.....completely flawless but i cant find the savaged kernel to pair it....

You should try that rom that I linked. It's really refreshing to experience true gingerbread 2.3.5. I love it and I use it as my daily rom. But cm7 is pretty amazing also.

dont know why i was so dumb i went with rc1... rc4 is even better ...what link? ill check it out i just am still confused about flashing a rom and kernel i know fn noob haha
sorry for the edit i meant to say im confused about flashing them both because the evo has been out for so long but it seems like there isnt that much for them or way too much there isnt really an optimal flash yet with both kernel and rom

I think it's a little bizarre to assume that someone can root the phone, s-off, and get a custom recovery on the phone but not flash a rom.....

Haha, I agree. But still, if you used revolutionary to root, like in my tutorial, then it was all automated. By using that method, the user doesn't have barely anything to do except for some small stuff like taking out the battery and turning some functions off. I'm just being helpful because I too was once a noob.

This was super helpful thanks for the guide

I am new, but I have a question why you didn't mention wiping things before flashing the rom? While I saw many other tutorials emphasized on wiping menu in the recovery mode.
Is that really a necessary step or not?

It is necessary, believe me. Wiping everything in recovery except for SD card is important between ROM switches. Otherwise you will run into so many issues.

Once you have successfully flashed a ROM do you need to keep the Zip file for it on your SD Card in order for it to work or can you delete the zip file?

Lost all hope...

It seems that I was fiddling with my OTA and I lost my original build Kind of bummed out, and also the fact that I don't even know how to do a full backup. I did a nandroid backup which doesn't even work. I update to the new ICS firmware and messed up everything...Now I'm left in a gutter feeling utterly upset and don't know what to do. If there's anybody who pity's me, please help. It would be sincerely appreciated. I just want to start off fresh.

Seriously, though, there are plenty of tools and procedures here to bring it back to life.
First off, before you muck things up further, I would look in your nandroid backup, and get the UID number. Hopefully you wrote this down somewhere before you originally messed with things?
For starters, I would goto this link, and see if it works for you...

At this moment right now, my a500 tab has that orange light on the bottom and it stays there, and when I turn on the tab it starts up normally like it would, and when it does it turns off. The strange thing is that orange charging light where the power button is, stays on even though I'm not even charging it.
I've tried changing the OTA, but after when it starts in the corner it says something like. " Not official blob" I'm not even sure I know what that even means....I have everything including nandroid backed up all the files into the SD card I had in my tab, I notice is there somewhere due to the amount of space it consumed on my SD.
So please! IF you know of any way to fix this I would be in great appreciation, also it's been a month since I've had this tab, as well I have a 2 year warranty.

Have you tried putting a stock update.zip on the root of your external sdcard and booting the tablet by holding the volume down button (left volume rocker) down while pressing the power button until the tablet finds the file and installs it. This should bring you back to unrooted stock ICS with locked bootloader and you can start over. Remember, this must be an update.zip file that is extracted from a stock RUU. You can't just rename a RUU file to update.zip.

Well, you get the orange light because your EC Pwr management is probably fubarred. That should be fixed when you install a stock rom as suggested in both mine and the other poster.
Considering you have your UID, you should be ok.
Of course I don't know if this is a 3.2 or an ICS UID. Best to have both. The sbk is the same, but the uid numbers differ.
If it's a 3.2., check the Q&A thread for a post I did for a guy earlier today.
But you should be able to follow the steps for the update I posted earlier.
Blob means Bootloader. And looks like you had an unlocked bootloader?
Try to roll back to 3.2. That's where I would start.

What do you mean by RUU? Also I've tried a couple of the OTA updates, when I first got the tab it was on 3.1 HC didn't even update it or anything, just had a custom ICS ROM on it. Do you think you can post the steps or anything on how to do this properly and go fresh? It would be sincerely appreciate buddy.

Hmmm....I'm not even sure what I am doing wrong but whatever it is, it seems to be not working. I looked for you post for the earlier person that you did, but don't know what it is under. By the way when I first bought the tab it was under 3.1 HC and after getting flexreaper it became to ICS 4.0.3...
So like everytime I turn on the tab it shuts down instantly, as well every time I try to boot an update.zip file onto the SD card it shows this animation of the android with this circular sphere in it's stomach after that it falls over with a red caution sign.

In my experience the common cause for ending up with a caution sign is a corrupted update.zip (incomplete download, bad SD card, etc.). As for the tablet shutting down, my guess is that's related to the power management functions being broken.

im not THEE most savvy here but i do know a few methods and find it easy to discover lesser known ones, i feel bad for you . if you want you can skype video me and ill try talking it over and maybe a few methods? :highfive:
edit: ok from what i can tell your update was bad and your bootloader is causing problems, the power problems are probably arising from the bad power management as moscow desire told.
the tabs obviously rooted n all right? ok so how about flashing the v7 ics bootloader then trying a custom rom?......<-also recommended by moscow desire

Hi Chismay, well I thought I fixed the issue and the problem. Guess again I did not This I can't believed I used a leaked ICS OTA, kinda ruined most of the things in my tab. Lol just had it for a month and already messed it up by fooling around with it. But your help is greatly appreciated buddy! Would like to get a one on one instructions on what I should do.
Cheers!

Correct me if I'm wrong on this...
1. You originally had Honeycomb on your tablet.
2. You flashed FlexReaper on your tablet
3. You probably got a recent version of FlexReaper.
4. You never upgraded your bootloader.
5. You can still get access to recovery.
If all of these are correct, then I think I know what the problem is. It appears you flashed a rom that requires the ICS bootloader and not the Honeycomb bootloader.
This, I think, is an easy fix...
1. Download the following file: http://www.darktremor.info/files/FLEXREAPER-R12.5-ICS-1.031.00.zip (this is an older version I have on my Acer A500).
2. Put the file on your SD card.
3. Boot up into recovery (if you can't get there, stop here).
4. Once you are in recovery, flash the FlexReaper file you just put on your SD card.
5. Now try to boot and see if it works.
Let me know how it works either here, in a PM, or e-mail me at [email protected]. If you need further assistance, don't hesitate to contact me.

Hahaha! Good job on guessing all that! I just followed your order from step to step and I was about to boot up normally! Everything might be erased and stuff, but hey at least I have my tablet working again :good: Case solved!

A500 tablet won't boot, stuck on acer logo screen

Dear forum
I know you guys hate noobs, but unfortunately I am one.
My A500 is stuck on the acer logo screen, and although I have read through many a post, I'm yet to find a noob-friendly tutorial. So help!
What happened? One day my A500 was out of juice. I plugged it for charging and got impatient. Pressed the power button too soon and too hard it seems. The tablet wouldn't boot beyond android screen. Tried soft reset, then hard reset (Power, Volume plus, lock). It reached the cog working android robot with yellow triangle once, and on trying repeatedly, it is now stuck perpetually on the acer logo screen.
So.
What do I do?
Do please break it down for me.
I do have an SD card.

Well, you can try this.
Go to http://forum.xda-developers.com/showthread.php?t=1816560
Scroll down the list till you find the a500 ICS update Roms. Download a couple of them.
Then go here and get the acer update decrypter http://forum.xda-developers.com/showthread.php?t=1869505 instructions for the tool are there.
You may not have to decrypt the Files. They may already be decrypted. You will know when you try to open them using 7zip or Winzip app.
DO Not Extract the files, just open it. Pull the update.zip to your PC desktop.
Copy the update.zip to your Ext SD card. Do not put it in a folder.
Boot your Tab holding Vol+ and PWR untill you see the package installation, then release buttons.
You may have to try 2 or 3 different update files, but one of them should work. They should be FULL Update files (300+mb)
It will install a fresh stock ICS, so if you had a unlocked bootloader, CWM recovery, and user data, say hasta la vista to them.

Thanks @Moscow Desire
Thanks buddy! I am trying this. Downloaded an encrypted ROM earlier, and the decrypter was old, hence couldn't decrypt. Now, I have found a decrypted ICS ROM, and have gotten as far as the green robot with a rotating polyhedron on its tummy and a progress bar. Let's hope this works out fine. Been waiting for the last 40 min and the update progress bar is still at around 25%.
How long do you think this should take?

Still stuck at the same point, almost 3 hours. Whatever shall I do?

Charge your tab, then try a different one.
It seems one won't work, but the other will.
The process shouldn't take but 15 minutes max.
I've heard where some folks had to do it 2 or 3 times with the same update.zip, but I would try a different one. Eventually it will work.
MD

Still struggling
Finding it hard to find either
(a) a working decrypter with a working key ($12 doesn't work anymore it seems)
(b) a decrypted update.zip, not too finicky about the version as long as it works
Do provide a resource for the above if you can.

Tell me the name of the Rom files you tried to decrypt, and the download link to them.
I'll check them out. Might already be decrypted.
Looks like it'll take awhile. After downloading, I'll pull the update.zip's and post them for you to a different server. Downloading slow......
EDIT: Decrypter tool works fine. Just decrypted 4 of the update files. You have to wait a couple minutes after hitting the START button. And there's no animation telling you what's going on, but after a couple minutes it finishes. I would also suggest closing and starting the app again after you finish with one. This clears the "Done" message.

Dowmload links for the decrypted update.zip's for the A500. For those having issues using the Decrypter tool..
Note: Remove the build numbers from the filename. They were only added to keep order. Rename to "update.zip"
41-124-01-update.zip
41-125-03-update.zip
41-203-01-update.zip
41-206-01-update.zip
Don't ask me which is better than the other. I don't know. But if you're tab's stuck at the Acer display, a working tab is better than a non-working tab
MD

Thanks
Thanks MD!
(Sorry I was away for a few days).
Gonna try this and let you know what happens.
Thanks again, you're a sweetheart.

update
Tried rooting with 41-206-01-update.zip
Curiously the progress bar (with Green android robot and rotating polygon) still stuck at around the same place (25%).
Gonna try another of these files and let ya know.

Trying 41-124-01-update.zip now.
On trying the same, it first came up with the belly up robot with triangle.
On retrying, the update progress bar again stuck at around the same point.
Well, still 2 more of these to try.
I wonder if someone else has faced a problem similar to mine.

Hoping one of them will work
Stuck at the Acer logo, usually represents 1 thing. Bad data in the Data partition. (corruption). Usually, runing one of the updates (some of them don't work) will set everything in order.
If not, well, not looking good.
MD

Ok. Tried all four. All of them get stuck at exactly the same point during the update progress.
Now, I'm stalled.
Any ideas, anyone?

Well, the "normal easy method" didn't work.
Ok, check this post. Guy had more or less the same issue. In the end, he started running EUU roms. EUU roms are exe files rum from the PC while connected to your tablet.
You can download them from the same sticky post in the Dev forum I believe.
It's the "flash everything" approach. Basically, he wound up back on HC 3.2, which is ok as you can normal OTA update to ICS.

Thanks, MD.
Will try this and let you know either way.
Thanks for your time. Highly appreciated.

Moscow,
I was also in the same boat, my tab was stuck at ACER screen after I rebooted one day.
I had NO custom ROM, everything was stock except I had root...
I followed your directions here and it works!!! :good::good::good::good:
I have followed your posts over the past year and appreciate you and everyone else here.
One question about those 4 packages you posted, everything is now stock? Stock ROM and Stock bootloader, etc...?
Just want to make sure!
Thanks again!!!
Malachi

hey cuban
Can you guide me to the stock ROM you used to reboot your tablet?

Yeah, you're going to be back on stock bootloader and no CWM. However, you're up and running!

Mannubhat, I downloaded all four of these but the first one I tried worked.
41-124-01-update., renamed to update, put on root of sdcard, boot tab volume+ and power, and that was it.
Good luck!

Already tried my man. Didn't work.
You lucky you.
