[Captivate Q&A, Help & Troubleshooting] capocaccia:
Anything gingerbread based is going to have worse battery life than a Froyo based rom. This is because the source code is available for Froyo allowing for some system processes to be turned off. These processes continuously run in Gingerbread eating up battery. If I were you, I would try out Andromeda3. Its an I-9000 based rom with great support if you run into any problems. Not to mention a BLN control kernel with voodoo lagfix.

If you need good battery life, I would stay with an i9000 or I897 based rom. They are super stable for daily use.
[Captivate Q&A, Help & Troubleshooting] prbassplayer:
Im having ALOT better battery on GB than what I ever had on Froyo roms.... Just saying.
[Captivate Q&A, Help & Troubleshooting] mrhaley30705:
I got better battery life on Continuum v6.1, kinda. On MIUI, get pretty good battery life. Big difference is on MIUI I leave background data on, whereas on Continuum I had it disabled.
[Galaxy S II Q&A, Help & Troubleshooting] Hearmeman:
Im installing a rom through rom manager and i did wipe data and cache and wipe davlik cache something like this and i pressed install and reboot and my device shows me white triangle and an android figure for like 5 minutes now is it normal?
[Galaxy S II Q&A, Help & Troubleshooting] Mr Bo:
Try to push Vol Up+ Home + Power button and you will come in CWM.

Flash the rom again

god luck
[Galaxy S II Q&A, Help & Troubleshooting] feryao:
Flash again. if you cannnot get a jig. It will help you afterward.
[Galaxy S II Q&A, Help & Troubleshooting] aceofclubs:
I see it written over and over again. Don't use Rom manager.

Use Odin or Cwm to flash.

Don't know the reason why just seen it not recommend and same problem you have so I've never used it.
[Galaxy Tab  Android Development] theduke89:
Omg this is incredible!!! You are a genius!!!

Summoned by my Heretic Tab
[Galaxy Tab  Android Development] lambstone:
Yeah this is a genius idea for our galaxy tabs. With this, I no longer have to worry about bricking my device via odin because of my ****ty faulty HP laptop. (it happened once and i had to send it overseas for warranty repairs, 2 months w/o my tab :( )
[Galaxy Tab  Android Development] AdamOutler:
I still need to prove it works.
[Galaxy Tab  Android Development] Nitro_123:
Good going Adam :D
[Galaxy Tab  Android Development] guaiwujia:
Congratulations～～～～～
[Galaxy Tab  Android Development] AdamOutler:
Its way too early for that... save that for the how-to thread.
[Galaxy Tab  Android Development] diagdave:
how to

Looking forward to trying this on my tab. You mentioned firmware would need to be made,I assume stock boot loaders could be used right away?how do we know which is grounded pad? What is the relay for?

Cheers

[Galaxy Tab  Android Development] cdesai:
Finally! :D
[Galaxy Tab  Android Development] AdamOutler:
Until I'm able to actually perform this mod on a device, I can't tell you anything. I don't know any more than what's in the first post.
[Galaxy Tab  Android Development] TheGrammarFreak:
I'm gonna go ahead and guess that you don't have a device to test this on? Or just lack of time?
[Galaxy Tab  Android Development] AdamOutler:
A bit of an update... Someone contacted me via PM to let me know that they bricked their device in the rare S5PC110 mode. This can happen if you damage your IBL from the IBL+PBL partition, or if the device realizes it cannot boot before attempting to do so. They were able to get their tab into download mode using the Linux Resurrector from the first post.

So, we've got the software part verified. Now, we need confirmation that the hardware mod will allow the device to enumerate as a "S5PC110 SEC SoC" on a Linux based system.

Someone please confirm that after the modification the device shows "S5PC110 debug mode" in Linux with the ModeDetect utility here: http://code.google.com/p/hummingbird-hibl/downloads/list
[Galaxy Tab  Android Development] lilstevie:
I pinged you on IRC, but ModeDetect shows "S5PC110 UnBrickable Debug"

Found a well-documented teardown manual at ifixit

http://www.ifixit.com/Teardown/Samsung-Galaxy-Tab-Teardown/4103/1
[Galaxy Tab  Android Development] AdamOutler:
Great.. Can you run the resurrector and verify that it goes into download mode?
[Galaxy Tab  Android Development] lilstevie:
yep, it does, only difference is that it is not a bootloader designed for this device, it turns the LED flash on, and doesn't bring the screen up, but in any case, heimdall can communicate, although I have not tried flashing from it yet
[Galaxy Tab  Android Development] AdamOutler:
Awesome. Try running a heimdall print-pit or a close-pc-screen to verify everything works. Ill get a one-click back to stock and a one-click CWM prepared for testing later tonight if that works.
[Galaxy Tab  Android Development] AdamOutler:
If you have the tools available, it would be good to probe around for the UART output from the device. UART is the first step to porting other OSs to a device.

My setup is an Arduino Mega. For probing I connect the RX line to a small piece of wire with a sewing needle attached. I ground the ground on the Arduino to the ground on the board. I then run minicom -D /dev/ttyUSB0. Set the options to 8n1 flow control off. Then probe around on the board while repeatedly pressing the power button so as to trigger UART transmission without turning on the device. Once you find a point with weird question marks, hold the power button, take a picture and annotate it.

The most common points are on the JTAG port. Usually they are opposite of the processor 's pin 0 dot. The RX and TX are always side-by-side. This would help people develop this device.
[Galaxy Tab  Android Development] devilng:
guys, you're **cking best! I was waiting for that! so, I have 2 questions:

1) if I disassemble my tab I will lose my warranty any way, isn't it?

2) I'm not sure with my english so can anybody translate it in russian (please no google translate, I don't want to loose my beutiful device).

thanks for answers

p.s. is there any disassemble instuctions?
[Galaxy Tab  Android Development] lilstevie:
I did that before posting it worked, that was part of my confirmation

---------- Post added at 10:34 AM ---------- Previous post was at 10:30 AM ----------

UART is pin 20 (RX) and 21 (TX) on the docking port, we have actually had this for a while, The jtag port is different on this device, it is along the edge of the board and coated so you need to scrape them back to get access.

---------- Post added at 10:38 AM ---------- Previous post was at 10:34 AM ----------

yeah you will lose your warranty when opening the device,

before getting someone to translate I would really make sure you know how to solder, I needed to use liquid flux to aid getting this done, and I don't normally use it ever, the points where you need to solder are fairly small.
[Galaxy Tab  Android Development] AdamOutler:
Can this be broken out? Can you run UART and USB at the same time? This is required for developing bootloaders and porting things like Linux to the device.
[Galaxy Tab  Android Development] lilstevie:
well linux has already been ported to the device, just FYI

but yes, USB and UART can be used simultaneously as the USB pins are not the same as the UART pins, one of the other users here found a Chinese clone cable that was easy for it, as in the standard connector the pins are NC, so he got 2 clone cables and connected up all the pieces to make one super cable,

I did it slightly different, I shaved the keying off the edge of a clone iPhone cable and did the similar thing with it, but I don't have UART on mine, I am probing around inside to find a more permanent wires out the side UART solution
[Galaxy Tab  Android Development] lilstevie:
As one final test I flashed an unsigned boot into Sbl position with GB IPL+PBL which requires Sbl to be signed.

?1
-----------------------------------------------------------
Samsung Primitive Bootloader (PBL) v3.0
Copyright (C) Samsung Electronics Co., Ltd. 2006-2010
-----------------------------------------------------------

ERROR.. Bootable SBL doesn't exist ..

was the output over UART, pushed the resurrector download mode button, then reflashed Sbl with heimdall and it kicked back into life,

great success :D
[Galaxy Tab  Android Development] AdamOutler:
Awesome! where did you download the bootloaders?
[Galaxy Tab  Android Development] lilstevie:
The unsigned and non working bootloader was a compiled version of u-boot for the odroid-a, the bootloaders I flashed back are from FUS
[Galaxy Tab  Android Development] AdamOutler:
Is there a link with instructions for heimdall? I am trying to put together a one-click. I don't own a Galaxy tab. I need pit, bootloaders and whatever else.
[Galaxy Tab  Android Development] lilstevie:
no, but there are links to them on this forum, or FUS downloader

---------- Post added at 02:13 PM ---------- Previous post was at 01:14 PM ----------

just a little bit of extra that I forgot to mention, Grounded pad is on the side facing the edge of the PCB, and the non-grounded side, the side we want, is the edge facing the SOC
[Galaxy Tab  Android Development] AdamOutler:
Please post a picture. It needs a picture.
[Galaxy Tab  Android Development] lilstevie:
I will post a picture, but mine isn't a perfect example, I miscounted the first time and removed xOM2 as well, although I will note that it didn't affect anything having removed that
[Galaxy Tab  Android Development] AdamOutler:
Just the UART port. and it's relative position is all.
[Galaxy Tab  Android Development] lilstevie:
oh my UART is not something that I am proud of, it is a crappy looking piece of plastic these days
[Galaxy Tab  Android Development] AdamOutler:
Oh, ok, I thought you said you were locating UART and then you found it. I'm working on getting a Heimdall One-Click package together. it will allow easy resurrection.
[Galaxy Tab  Android Development] AdamOutler:
Stand-by for: Heimdall One-Click [Stock 2.3.3] [xxJQ1]

wrong page
[Galaxy Tab  Android Development] AdamOutler:
I would appreciate it if someone would take the time to:

1. turn the device off

2. run Ultimate UnBrickable Resurrector (Galaxy Edition)

3. run Heimdall One-Click to return the device to stock.

This will give me enough to finish the Galaxy Tab project.
[Galaxy Tab  Android Development] hex007:
is there any way to make it temp mod which can be used to recover a bricked device using unbrickable mod and then restoring it is it was before

can it be achived using only wires or external resistors rather than making the device permanently unbrickable by removing the resistor . most of the devs may not be so comfortable with a soldering gun

and last but not the least i appreciate the effort and time your team put into this mod. thank you
[Galaxy Tab  Android Development] AdamOutler:
no

No there's no other ways. Your other option is to pay $50 for JTAG or $200 for a JTAG box. These methods require a lot more soldering and special tools.

This is easy compared to the other methods. Its the DIY method. I charge $30+ shipping for this mod. Its the best brick recovery available and it turns your device into a development board.

Thanks for the props.
[Galaxy Tab  Android Development] diagdave:
I have managed to perform this mod, it did flash and i managed to enter recovery. However due to my bad soldering its not booting, does anyone know of an alternative xom5 point (non grounded) that i can use? Ill upload pictures for relative location of resistors if needed tonight.
[Galaxy Tab  Android Development] lilstevie:
it may not be your soldering, I thought this was the problem at first, but hooked up to my computer it will not boot, plug it in to the wallcharger or unplug it, and hold down the power button for a few seconds, the touch strip will light up when you have held the power button long enough.
[Galaxy Tab  Android Development] AdamOutler:
Software resurrection is online.
[Galaxy Tab  Android Development] mikile:
Helo, this is my first post here, and the reason for it is that I bricked my NEW galaxy tab gt-p1010 trying to upgrade it to android 2.3..

Since I have some experience in electronic, maybe I will try to mod it to unbrickable mod, if it is possible.. hope with your help.. and maybe that help someone else...

here is the main board with cpu..

And I wonder where the resistors are???

markings on CPU are:

SAMSUNG 107

KAT007015-ARTT

!!!Help!!!
[Galaxy Tab  Android Development] AdamOutler:
I don't have that mod listed yet.

If you want, you can check out the 8 resistors lined at the bottom of the processor in this picture.

6 out of 8 will be xOM resistors. You will need to probe to find out the order. Use the methods I outlined here: http://xdaforums.com/showthread.php?t=1338073

Someone is sending me one of these devices so it won't be long before I have a guide ready. Be proactive or sit tight, it's up to you.
[Galaxy Tab  Android Development] mindmachine:
I can cofirm this method as working

Good day.

Bricked my p1000 by flashing wrong firmware due to unattentiveness. Screen stayed black and there wasn't any reaction to pressing volume power whatever. Okay, s***, obviously hardbricked.

So I dismantled my tab (have done before as I bought one with a broken glass at Ebay and a replacement touchscreen in china for 15 € following the ifixedit manual except for the heating, i used my oven at about 90 degree Celsius) and removed the resistor by touching it shortly with a soldering iron and removing it with a tiny screwdriver. Next I tried to bend the leg of a diode to an u but as it was to tiny, I couldn't place it properly to the board. So finally i used a short piece of electronic wire and soldered it to the board.

As I had to use a normal soldering iron (sharpened but still quite thick) I never expected to get any sign of life from this device anymore. But...

IT WORKED!!! :-)!!!!!

Using the resurrection tool it showed the device in Download mode. I used heimdall from linux command line twice and rebooted and voila, the tab is alive again.

Gonna rebuild it (left the case open while testing) and think what to do with it next ....

So thank you very much for this lifesaving thread.

Kind regards

[Galaxy Tab  Android Development] enelyam:
I have a question, i have made the unbrickable mod to my galaxy tab. I think i did it the right way but now my computer recognizes the tab as a SEC S5PC110 TEST P/D but it has a triangle on the devices manager. I know its something about the drivers, of course. But i would like to know what step to do to solve that. Im running windows 7 64, have java and all those programs installed.
[Galaxy Tab  Android Development] AdamOutler:
Use Linux. We made some software for Windows and located drivers, but because it's windows, it's flakey. Works every time in Linux. Install linux. It's free.
[Galaxy Tab  Android Development] enelyam:
Yes i do have Ubuntu 11.10 even though right now its only installed with virtual machine on windows. But Just a moment ago i found that unbrickable resurrector says it didnt find the device. I mean it sends some kind of warning and then it says it failed to find theme pix or something like that. I double checked the pads i soldered and they are ok. And in fact Windows 7 recognizes the TAB as S5PC110 device so i guess i did it right. I think the only thing missing is a driver or something. Unless i have not configured something on the virtual machine so that linux doesnt recognize it...
[Galaxy Tab  Android Development] AdamOutler:
you're using windows. Use Linux. The device is connected to windows and therefore it requires drivers and will be flakey.
[Galaxy Tab  Android Development] enelyam:
Yeah, thanks. When i checked the virtual machine settings it was not allowing me to connect USB 2.0 devices. I guess thats the issue. I will install Ubuntu but as dual boot so that i can boot Ubuntu or Windows instead of using a virtual machine. Will keep you update...
[Galaxy Tab  Android Development] AdamOutler:
In order to use a device in a VM, you need to register it with the host. The device is attached to windows. While it is possible, it only works one in 5 times.
[Galaxy Tab  Android Development] enelyam:
Yeah thanks Adam, i think that will solve my problem. Anyways i always like to have both OS on my laptop. Thing is that when i formatted this one i have now, i didnt installed Ubuntu from the get go. And im always afraid when i try Ubuntu dual booting with windows that it will break some of the windows configuration or files. I have too many thigs inside my laptop that i need and are to find now that so many links have been down.
[Galaxy Tab  Android Development] cdesai:
Head over to easybcd forums, and follow their guide - you'll be all OK

Also @Adam, I've been messing with mtd lately, although I did get it correct and now we have a working driver , but i'ld like to know if there's a way to recover if we mess up OneNAND - I doubt this could help.

[Galaxy Tab  Android Development] enelyam:
Where is it exactly that you receive donations Adam? Youre thruly a geniuos!!!! I installed a separate Ubuntu 11.10 on my laptop. And as soon as i installed java i ran the resurrector. It works like a charm!!! So where exactly is that i need to donate??? For real... I mean i have not get the tablet in download mode but the program reconizes it with the screen it should. Im a very happy man right now....
[Galaxy Tab  Android Development] enelyam:
Ops! Looks like i was celebrating too early... Everything worked fine, but then when it was almost done flashing it disconnects and says wiping cache and it stays like that. So there is something missing because it wont aloud me to flash the bootloader using heimdall. Also when i turn it on it goes straight to recovery, at least it turns on now(It was bricked as hell). But theres an error that says E: failed to mount /preload (No such file or directory) and E:install_application_for_customer:cant mount /preload. Then a bit lower it says your storage not prepared yet, please use IU menu for format and reboot actions. copy application failed

Could that be because Its a p1000n and its not compatible with the heimdall package done by Adam? Or is there something im missing in here? Thing is that the power button doesnt respond inside recovery now, so i cant apply factory reset or anything like that. Heeeeellllllpppp! lol
[Galaxy Tab  Android Development] AdamOutler:
Actually, this is what UBM specializes in. You can't mess up the OneNAND on an UnBrickable device. This will fix any OneNAND related problem. Just don't blow any efuses on the processor because nothing can unblow efuses. Just keep a backup of your EFS partition, that's special and you can't rebuild it.
[Galaxy Tab  Android Development] AdamOutler:
If you send a donation with the donate button in the UnBrickable Resurrector, I get a note with it so I know to split it 50/50 with Rebellos(designed HIBL and modified SBL). If you would like to donate directly to me, send it with the "Donate To Me" button above my avitar to the left of this window.

Glad it worked!

Try using Resurrector R40 and as soon as the Resurrector reports it's sucessfully uploaded the SBL, disconnect it. The device will not enumerate with the computer until you plug it in. Boot into windows and use an Odin package... I don't like recommending Odin, but I don't know what a p1000n is.

Use the home button if power doesn't work.
[Galaxy Tab  Android Development] enelyam:
Well, just to clarify a point the P1000N is the P1000 series of galaxy tab use by ClaroPR. I think the mess is about the ginger bootloaders or something. I think my tab bootloaders are secure from stock. Since i didnt pay attention to details i got into this mess. I wonder if i try to flash a stock Froyo it from latin america it will be back? At least i can try all that thanks to you and Rebellos and all the people who made that modification possible :)

Edit: home button is not responding, i tried every single button but nothing. in fact i tried that the first time it booted on recovery mode
[Galaxy Tab  Android Development] cdesai:
Good to know, so now one day I really gotta do this

And I've always had a backup of efs, so only thing now is the soldering part ;-)

Any chance you might be able to do this for s5p6442- no data sheets but I might be able to get you some pics of a open device when @ home, or just open my profile and look out for a thread I made in Galaxy 3 General (REF - Service Manual is the name ) it had some pics of the phone disassembled

[Galaxy Tab  Android Development] enelyam:
Okay, so now i have the infamous MBR error when it goes to recovery after i flash. So is there a way to repartition without been able to pretty much do nothing with the tab? I mean like something with Ubuntu or maybe gparted? Been trying hard to flash different roms, i found a Froyo that is compatible with the P1000N from latin america. Since the problem started with Froyo, the bootloader on the tablet i guess is still Froyo. At least the one that works, because if i try to flash a ginger Froyo, the tablet just wont do anything. But the Froyo one puts the tablet in recovery although recovery reads the error messages above stated.
[Galaxy Tab  Android Development] enelyam:
Well, after all the struggles i went thru im very happy to say that i have been able to fix my P1000N!!!! Wohooo! Ended up creating a firmware myself using the JM9 posted by Humberos and lucky enough i had the pit file for ClaroPR. So i can confirm that the method does work because i think i gave that tablet a lot more than i thought it can handle lol... So the guys who made possible that modification are the real geniuos behind all this. Thanks a lot for your help guys!
[Galaxy Tab  Android Development] PriMarius:
Hi,

just to make for sure I understand the Hardware mod part,

please somebody who made it confirm.

particularly: is the bridge connected to the appropriate terminals?

(red x = xOM5 to remove)

(red line = bridge to make)

(red .... = alternative bridge)
[Galaxy Tab  Android Development] enelyam:
Yes, that is exactly what you need to do. The XOm5 has to be remove, and the non grounded pin which is the one with the red trace line will be connected with a jumper to one of those xOM0 or xOM3. If you do that succesfully youll be able to flash everything you want to your p1000. Trust me, i have a P1000N and it was as bricked a a tab could be because in my case i erased everything inside the tab because i erased all partitions with clockworkmod thinking i was doing something good(Duhhhhhh). And i was able to recover the tab with that mod. Also, so that youll not have issues after that like i did. If you dont have a linux OS try to install it so that the Unbrickable resurrector will work as it should. Windows seems to have too many issues.

Edit: After you apply the resurrector you may find that the tab doesnt do anything. But like Adam says in his tutorial, if you see the download mode picture inside the program the tablet is in download mode no matter what. Also make sure that you have a Heimdall package that works with your tablet and you can use with linux because for example in my case i didnt at first. And when i tried to disconnect it to change from linux to windows the tablet will turn off and it was not going to be recognized on windows as download mode. Unless you do what i did which was creating some kind of combination on heimdall to flash on linux so that the tablet will get a flash(even though it didnt work as it should) the tablet will reboot in download mode and that way you can change to windows and flash it with Odin with the right firmware for your tab. After all, my problem was that the latin model P1000N doesnt have a lot of support in terms of firmwares and stuff like that. But if you have a P1000 you should be just fine... Good luck!
