[Q] [i9000] cyanobricked

Hi there,
I noticed I can't get in download mode anymore. Whatever I try it won't show the yellow triangular download sign. It just boots into cyanogen.
I have tried the 3 button trick but recovery nor download works. That's when I had the idea to apply the 3-button fix. adb reboot recovery brings me in the cwm recovery mode. adb reboot download just reboots the phone. I even tried the 300k ohm jig which always seemed to work as a failsafe. That also just boots the phone into cm.
I have checked with my brother who also runs CM nightly 101 and for him the download mode works fine so it is my phone, not CM.
The phone works fine now, is rooted too so I wondered if there's any way to fix this by rewriting the bootloaders. I want to have this fixed as a failsafe is flashing ever fails or if one of the nightlies gets corrupted.
Is there anyone who can confirm the download mode is in the primary bootloader (boot.bin from a stock rom) and is it safe to just flash_image that to the boot partition or will that be a guarantee to brick. The idea is that I still have root console access so I have to fix it from there.
Any help is appreciated.

Thanks for the quick reply.
Tried the tricks with and without pc-usb/charger and it made no difference. The 300k ohm jig trick can't be done with power or computer connected since you have to use the usb connection on the phone for it. It usually was my ever working failsafe.
I also tried the quickboot app without any luck. It seems it is responding to the download command but the code isn't there anymore.

Hey try going into download mode by touch controls although I haven't ever used cyanogen but i assume as every custom rom has this feature cyanogen must also have this! The download mode option in quick network options when u press the power button for 2 seconds ! Although it isn't safe but you cab try this and then if it goes into download mode then their must a way to go into download mode manually!

Holding the power button for two seconds indeed brings up the profile/reboot/shutdown options. Selecting reboot only gives two additional options, reboot and recovery which do as they say. I can boot cwm recovery but from there I can't go into download mode either.

Try downloading terminal emulator and then reboot download or ADB reboot download

Tried it from the terminal with reboot download. Also tried adb reboot download long before that. It just reboots and starts. I have the feeling the piece of bootblock that's holding the download mode isn't there anymore.

There is an option in recovery to boot into download mode, Have you tried that ?
It sounds to me like that part of the bootloader is corrupt / missing.
Does the phone still work normally ? can you still continue to use it daily without the download mode option ?

The phone works fine otherwise. I just want to fix this before it stops working fine and I need the download mode.
Recovery boots into CWM-based Recovery v4.0.1.5 which I got with CM7 with no option to return to the stock recovery or download mode as far as I can see. Also zipped updates from sd-card install fine from CWM recovery mode. If I just knew where to find a cwm ready zipped bootloader that will fix this.

Thats a good idea, I think that should be made, Would save a lot of hassle...
In my recovery under 'advanced features' the option is there to reboot into android or reboot into download..
In order to go from CM7 - Stock, do you need re-partition with all 3 files ? or can you flash it through recovery ?
If so, flash it to stock and sell it to someone who has no idea about Custom ROMs / Hacking. (like me 12 months ago )
EDIT: is this issue not kernel related by any chance ?

Well I have no clue to make any package and I don't dare to flash_image some random boot.bin.
My recovery -> advanced only has reboot recovery which brings it back into recovery.
I'm afraid bringing it back to stock also needs odin/heimdall, that brings me back to the initial problem.
Selling it gives me the money for half a new phone. As long as its working fine I'd like to stick with it. My worst case scenario so far is that I'm stuck with CM7 nightly #101 for the coming 1.5 year which is annoying but far better than the slow stock samsung hands out.
The issue can't be directly kernel or CM7 related. My brother has CM7 #101 running and download mode works fine with him. (And no I can't secretly swap phones ) He doesn't know how to work with odin so I arranged everything for him. Exactly the same steps as I did my own phone. Perhaps a glitch in flashing or something.

Hmmm... tricky one to fix..
I have no more ideas i think flashing bootloaders through recovery would work like you said, But unless its a tried and tested method i wouldnt recommend it at all.
Have you posted this issue in the CM thread ? perhaps you could PM one of the Devs for assistance, or whether the whole 'flashing bootloader in recovery' idea would work at all.
You have nothing to lose by asking them.
Hope you get a solution... But until them im out of ideas.
Keep us updated if you get a fix.
Good luck man !!
EDIT: one more idea, Sounds risky but.... What if you made a nandroid backup on your brothers phone and restore it on yours ?? Thats if nandroid does back up bootloaders im not sure

Thanks for thinking with me. I'll give the nandroid solution a go if there are no other replies within a reasonable time.
I'll post the same question in the CM forum but contacting the CM devs could be hard. They don't give any official support to nightlies and I can't say I'm convinced it has anything to do with CM at all. Though they do have the knowledge to answer the question or build a package to repair it. But you're right there's nothing to lose in asking.
Ofcourse I searched the forum before posting and found out I seem to be the only one ever with this problem. The solution could be as rare so I'll keep you posted if I make any progress beside here. That's what the whole idea behind this forum is for right?

True man !!
And if you get a solution or a dev to make a flashable bootloader. It could help other people in future
Good luck. Keep us posted

Interesting but that project still needs a bricked i9000 to tear apart. I don't have a captivate. Well if it ever becomes really bricked I'll consider donating mine.
And I'm okay with handling computers (yes I consider the phone a small computer about 400 times faster than my first pc) but when actual soldering is involved I give up.

fixable?

Hi! If it still doesn't work, try downloading ROM Manager from the market and install the latest CWM. It sounds like your bootloader got modified/locked.

Unable to reboot in download mode

I find my newly purchased tab 8.9 very laggy with the stock TouchWiz

I carefully followed there instructions but I am unable to go past the downloading droid. once I validate with the right button volume, the tablet simply reboots.

I see. The Overcome thread also has the CWM Recovery as a .zip file which is flashable through Stock Recovery (same procedure as flashing Root). You just put the file in your internal SDcard and flash away. If you still have doubts, read a little bit here, as I'm sure that will clear any doubts you might have.

Don't expect perfection from a port, ever (port = a ROM that's not native to the device). The motley kernel, along with UV can help you in the battery department.

My system right now is a stock ROM us retail P7310UEKHA flashed with CWM and CWM and I want to install a 3.2 stock ROM using ODIN.
The way I try to access the download menu is
1. Turn off the tab
2. wait 30 sec
3. restart with the down volume pressed
4. when the reaching the menu between recovery and dowloading. Select dowloading with the down volume button and validate with the up volume button.
Result: a black screen for 3 seconds and then the tab reboots

Thanks!

Still no luck...
So I have tried reflashing the stock US retail ROM and ran the EULA3 OTA update over it. I can't seem to figure this out.
The OTA update entered the download mode for a few seconds during the update so I am wondering if I don't simply have a locked bootloader.
I have made a video to show the problem: http://youtu.be/b09-x31ldbs

[Q] Need to straight up nuke my I9000 - Many an issue

Hey guys, it's been a while!
Anyway, before I even got my I9000 I had everything sorted to install Darky's ROM and the Speedmod kernel. Some time between them working perfectly and now, I plugged the phone in to Kies and it has tried to update me to GB. SM and DR did not like this.
I managed to do a factory reset (or whatever it is in CWM), and that got the phone to boot, but it isn't pretty. I get the kind of graphical messing up that a dying GPU would render whilst booting the phone, it reboots 25% of the time I am using the music player, and I can NOT boot in to download or recovery any more. I already tried plugging it in to Kies in the hopes it could just wipe the phone over and start again, but it simply does not recognise it.
Likewise, I would look in to the files I need to just do the equivalent of a full format with Odin/ADB, but without download mode I don't think that would even work.
So, the question is; just what the **** am I supposed to do?

USB recovery jig.

can you get into your phone ??????????? I mean can you reach Settings ???? because I didnt read all your speech .

Search for "recovery.tar" and flash it with MOBILE Odin, this would give u cwm and flash a new rom in cwm or flash a stock rom with mobile Odin. Good luck

EDIT: This recovery.tar; should it be on my phone already or do I have to find one? Because Astro can't find jack **** on my phone.

"Flashing...
Flashing Kernel..."
for the last 10 minutes...
Thanks for the replies so far guys!

solved it ???????????

Nope. Sorry, I have been editing that post rather than enter new posts (until someone else posts, of course).
EDIT: Still flashing...

Ok, it now won't boot at all (stuck at the Samsung splash load screen), BUT, importantly, I can get in to download mode and CWM recovery.
What do I download and do to entirely wipe the **** out of this phone and start again?
EDIT:
Fixed. Sorted. Thanks for your help guys, it is much appreciated.

[Q] Still dead after Unbrickablemod

I performed the Unbrickablemod hardware modification the other day with a friend. We did it and it showed up as the dev board. I can successfully boot it into download mode and use the one-click install in the thread. (Here: http://forum.xda-developers.com/showthread.php?t=1312391)
But that's where I'm stuck. Heimdall performs the one-click successfully, but my Tab doesn't boot up, and the screen stays off no matter what. I saw someone having a similar issue in the main thread but they didn't post again. Someone else posted that you can get the power strip light up if you unplug it and press the power button a couple of seconds, or if you plug it to the wall charger. Both worked for me too, but I don't know where to go from here.
Any help is appreciated.

It's a GT-P1000 and I used the one-click Heimdall suite provided in the OP. I also tried Turkish firmware I downloaded from samfirmware with heimdall command-line tool. (1.3.1) Still no luck. I'm not sure what I'm doing wrong.

I wonder if you can still make the unbrickable to kick into dev mode again?
And use GB-stock-safe-v5 from overcome instead? (link in my signature)
it is a complete JQ1 (Italian) rom.

Oh, download mode via Unbrickablemod still works, I guess that's the only beacon of hope that keeps me going. I'll try it once I get back from work. I can't use it if it's in Italian, but the important thing is getting the tablet boot up and enter the recovery on its own, right?

It is European ROM, it has English.
But it is stock. If that boots, it is resurrected.

Finally got some time to work on my Tab.
I got the files, didn't know how to use them with Heimdall since the tutorial was written for Odin. Extracted all the files and followed Heimdall's usage. I guess I got something wrong, but magically, the screen came up showing the "Downloading" screen. Then it rebooted into the infamous glowing Samsung logo bootloop with vibration.
I'm now trying to go into download mode, if anything comes up I'll post about it. I have no idea how it worked but now I know I didn't bust the screen somehow when I performed the hardware mod. Thanks!
Edit: I can get it to download mode by itself. Now I need to find a PC with Windows to try Odin. Shucks.

By the way, I tried flashing Technomancer's kernel provided in the Cyanogenmod wiki to instal CM directly, but can't boot into recovery. I guess I need to complete Overcome flashing, then try flashing CM. Does that sound correct?
Edit: Thanks to this tutorial, I have successfully managed to flash Overcome and I guess CWM is also installed. My Tab is finally revived! I'll keep you up to date with the progress on installing Cyanogenmod. Thanks for all the help!
Aforementioned tutorial: http://forum.xda-developers.com/showthread.php?p=34692020

I kept following the Overcome manual, managed to install Overcome kernel and now I got CWM working! It's backing up current Overcome installation right now, I think I'm doing it right.
Edit: It's done! I got CM9 on my Tab and it works great! (Kinda. No official CWM sucks.) But it's great. I'm happy that I turned my Tab back from death. Thank you so much.

Glad it is revived.
Yeah, I am quite dismayed that cm wiki doesn't recommended overcome kernel when it is obviously the one that works best.
Sent from my GT-P1000 using xda app-developers app

After all the headache I endured, I really wish they'd written a more through wiki entry for Galaxy Tab. But Overcome works like magic, and after flashing Overcome, Cyanogenmod installer zip easily flashed newer CWM versions. It's up-to-date and works great. Thanks again! More people should know about Overcome.

[Q] Gti-9000 jellybean install

Hi, I own a SGS gt-i9000, and i rooted it with Z4root. I'm trying to update my android to the jellybean 4.1, with absolutely no success, this is due to my lack of experience with the android OS and clockwork mod and so on. I tried everything i could, nothing seems to work, first because the CWM doesn't work for GT-I9000 for some stupid reason, and second because, as I already said, i am a giant noob on this OS.
What I'm asking for is a simple way to upgrade to jellybean 4.1 OS that even a bloody rock can understand, sorry for the expression, but i'm really mad right now. My phone specs are:
firmware version: 2.2
I9000BUJP5
Kernel: 2.6.32.9 [email protected] #1
FROYO.BUJP7
Thanks in advance.
P.S. I have already read threads about doing the same but i failed to understand every thing.

Hey,
First times can be frustrating! Seriously, I got really mad when I was trying to put CM9 on my phone.
Easy steps? I'll try make it as simple as I can.
First, make sure you have your desired ROM on your internal SD, and Gapps (Google Apps) if you need to.
1.) Put your phone on 2.3.6 XXJW4 firmware using Odin. This is done so you have the right recovery- maybe explaining why CWM didn't work for you on Froyo. If you need help with this, feel free to ask
2.) Using Odin again, flash in CF-Root. You can find this somewhere in the Development forums for the I9000. I'll see if I can post links later. And again, if you need help, don't hesitate to ask
EDIT: Here you go make sure you find the right one... It should have XX and JW4 in the name.
http://forum.xda-developers.com/showthread.php?t=788108
3.) Reboot into CWM recovery using the three button combo (Vol Up, Home, Power). From here, using the volume buttons to scroll and the home button to select, go Wipe Data and Wipe Cache. They're both on the main screen so you'll see them instantly.
Then go into the "Advanced" menu and click Wipe Dalvik cache.
4.) Now go back to the main menu, and select "Install zip from SD." Navigate to where you left your ROM. It'll ask you to confirm. Select Yes.
5.) Wait for it to flash in. It'll probably be really quick.
6.) You might end up in a bootloop. DON'T PANIC. YOU HAVEN'T BRICKED YOUR PHONE. Simply take out the battery from the back, put it back in, go back into recovery. Flash in the same ROM again, from the same place using the method in step 4.
7.) Wait for the rom to actually flash in this time.
8.) Done! It'll say its finished.
(Optional step for Google Apps: if they're not included in the ROM, you have to flash them in seperately. Once you finish step 7, wait for the phone to reboot. Then turn it off, go back into recovery and this time select the Gapps zip from your SD).
Hope I made it easy- if you have any questions, please, feel free to ask me either here or by PM

Hey, thanks for the help, i just installed the xxjw4, and the phone starts but it doesn't go anywhere, it just keeps on showing the "S" logo glowing, then reboots and does the same thing over and over. What is it that's missing here??
Thanks in advance.

Hey again,
Hmm, okay, see if you can find a file on these forums called dbsdata.rfs.tar. Try flash through Odin.
I think this is the file you're missing here- but I'm not sure about this...
