before asking for help - P3400 ROM Development

lots ppl do something wrong with there devices and if device not start they create new thread and send message to all ppl, some time they send same message again and again
here is some tips before asking question
1. if you think your device is dead first this is to do is don't be panic (its very hard to say anybody to be cool when there device is stop workin you can't do anything now lots of times you do wron things and make problem bigger
2. remove battry put after some times and check what happen
3. search on xda forum (use google search engine/google castom search )
4. while conneting phone to pc check that you see device in device manager (i wil explain it latter )
5. while asking help first tell what you do before phone is dead
6. tell what you done after device dead
(i m writing this from opera mini so forgive me for my bad english )

dear mr lumpistefan

mr lumpistefan
i have posted many posts on the forums and have emailed you for help but you never seem to reply sir ,and you seem to be the only person who can actually help me if you can pls sir as i cannot get my wallaby working like i said ,,all i get is when i plug in the usb sync lead on my pc in device manager i get HTC USB SYNC ,,what ever flashing software i use it wont work it says please connect via active sync but i cant as i have no rom on pda also i have no bootloader to flash via sd card ,,and fix bootloader tool wont work either as it wont connect with pda or communicate
i no the device can be recovered because its still working just needs the software rom and bootloader back so if you can show me how to flash my pda back to life i would be very grateful ,i have checked continously on the entire forum for my problem and i coudnt find nothing related to it
I agree
Tends to be a common problem and I've been coming to the site for months looking for help and have yet to find it. Any help would be appreicated.
Hello pdaman.
Sorry, that you didn´t get an answer from me, but do not know any other solution than mentioned here in the forum. I think the device is stuck, because you don´t have access to the bootloader to flash a new ROM via SD, and you can´t repair your bootloader, because the device do not came up , so that you get an connection via ActiveSync.
I personaly do not know any other solution to reflash the device....
Stefan
maybe this for the bold and brave
http://wiki.xda-developers.com/index.php?pagename=WallabyJTAG
i dont get it ,,,,if the device shows HTC usb sync in device manager and the device is working fine just needs bootloader and rom back how can you say i,m stuck ,,,i spoke to many pda engineers all quoting me around 30pounds sterling to fix it so it is possible to do so oh welll it seems 1000's of people using this forum hasnt come across htc usb sync before? when i check on google htc usb sync i see that the treo handset uses similar features theres even special rom flash software that communicates with my pda right now but again there for treo and i contacted the software developers but no reply
i am trying my best to find a cure for this ,,,i,m so glad my blueangel device isnt as crude as the wallaby as i destroyed the bootloader many times on my blueangel and recovered it in seconds but the wallaby is so delicate
i will keep everyone posted if i find a way of flashing a wallaby device while theres no bootloader and os on it and it shows HTC usb sync in device manager and if theres anyone out there reading this please please share it with us as i,m sure i am not the only one who has this problem
know that ur frustrated but if the Stefan said that he honestly dont know the solution than why blame him bcoz "device is stuck", he helped to a tons of people about software problems with wallaby and Im sure that he would help you too if he know the solution

[Q] Cyanogenmod 7 boot-loop

Hi! I have no idea now what to do, so I decided to ask here. I'm already very depressed because I can not find a complete solution
When I installed the CyanogenMod 7 phone will not boot. Is suspended at startup (logo CyanogenMod) and nothing more I can do I have read many manuals, but none has not helped me. Apparently you need to do recovery (?), But when I try to run this menu, nothing happens and the system tries to run. At first I thought it was enough to wait, but even after several hours, nothing moved, and the phone became useless Can I do something about it? Is there anyone here who can I explain it as simply? And please do not refer me to other instructions, because it can not much.
It would be good if the aid was in the Polish language, but of course also happy to get help in English

which rom did you flashed?
which kernel are you using?
then, i'll see if i can help you
PS : dev forum isn't the right place to ask...
post in the "Q&A" forum from now on, pleaseeeeeee
buddy, please post these questions in the Q&A forum....you are spamming the development thread.
as of your problem, u can do two things,
a) use SEUS and reinstall 2.1update 1 from SE (click support zone, click phone software update and then click "repair phone" and re-root your cell from start
b)use the x10 flasher tool from xda,download the E10i_2.1.1.A.O.6_Generic.zip from the net, extract contents and copy them to the firmware folder of the x10 flashing tool....connect your phone in flash mode when asked and your done

if he just tried to flash miniCM7-2.1.1 with a stock kernel he just needs to unlock his bootloader, and then flash nAa's kernel and then reflash (no need to start from SEUS many problems can be solved without SEUS)
I'm sorry, probably not I noticed a good place to put questions :/
I have x10 mini pro
Cyanogenmod 7(?) I'm very noob in this topic.

the Q&A for both phones is here
so wrong place, wrong phone
...
could you to link the rom you are using?
You' ve probably flashed the 7.1.0/7.1.1 without follow all the required steps... I agree with friend that told you to unlock the boot loader, then install nobody'satall custom kernel and then reflash the rom! Also once i had the same problem... It caused because i didn't have made wipe/factory data reset! i pressed the power off button and the central key together in order to stop looping and reboot the phone...
I have to wait until someone moves on, or start a new topic in the right place? Once again, sorry
Probably the "use" the latest version of CyanogenMod. CM v10.
What should I do?

[Q] Galaxy tab 10.1v unrecognized by computer

Hello everyone,
I recently bought a "second hand" GT 10.1v, for which the previous owner tried to root it and install a custom firmware. He told me he had a problem during the processus and now the Tab is runs in an infinite bootloop.
I though I would be able to fix it (I have a GSII which I customed a lot so...), but I guess I was wrong... I've been looking for some answers for the last 2 days but can't do nothing. Here's the problem :
* I tried to do the method to root the device one more time. I make the button procedure to arrive to the screen with the usb plug and the android working in a triangle.
*When I choose the usb plug, I have these informations written :
fastboot usb download protocol
bootloader version : p7100BUKC8
baseband version : P7100BUKDF
serial number : the serial is written
lock state : unlocked
*When I choose the triangle, I have these :
reason : force key
secure mode : secure
check signature : check
oem lock : unlock
waiting usb cable...
Regardless of my choice, I can't have any communication with my computers (running under windows 7 x64 or windows vista x86)
*I tried with Odin (after choosing the triangle), the device is not recognized in odin.
*I tried with fastboot mode, following step by step different tutorials (this one was the first) with installing usb drivers via google sdk, modifying the android_winusb, moving adb to "tool" folder, adding the fastboot nvidia to this folder.
When I type fastboot devices in cmd, nothing is written. When I try fastboot oem unlock, it shows "waiting for device".
When I type adb devices, I have a blank list of devices.
The problem is that when I plug the usb cable to the computer, windows doesn't try to install drivers and I don't see Android phone nor ADB device or something like that in the device manager of win7???
I'm totally desperated, could someone help me to fix my problem??
Sorry for the length of the post but I prefer write as many informations as I can so you don't waste time by trying to help me on something already done.
Many thanks to you all!!
Using windows7 I'd reinstall the usb drivers as a first step. If it says the drivers are already installed, install them anyways, and see if that gets you any further. Hopefully it will.
Plus hopefully someone with more experience with 10.1v will come help also.
If you see this it was sent using my GT-P7510.
Hi Benzoman,
Thank you for your prompt reply, but as I said, the problem is that windows doesn't even detect it. How can I install the driver if I have no device in the windows device manager?
download the driver from Samsung or wherever you want and run the download. I'll post a link in a minute.
If you see this it was sent using my GT-P7510.
EDIT: Just noticed your posting for the 10.1v No experience with this version myself personally but try the following links.
Post for unlocking which includes USB Drivers http://forum.xda-developers.com/showthread.php?t=1064793
Thread referred to in first post for Windows Users http://forum.xda-developers.com/showthread.php?t=1083517
Like I said I haven't messed with the 10.1v myself so I would follow the original thread instruction first and see what they do for you. Else ask for help with the problem somewhere appropriate for the 10.1v there unless you already did.
Thank you for your help, but I still don't understand, and this is for every type of device, how can I install driver if the device is undetected by windows?? In the device manager, I don't see any unknown device or something equivalent...
You have the same issue as i do, The COM ports won't be able to be read until the device itself has loaded/opened it's COM ports to be able to communicate. Your best bet would be attempting to get it to detect via APX mode. Once that works, your only solution to getting it to boot/flash firmware normally? would be to drain the thing dry
PS- I posted a guide on here on how to get it out of the "Endless boot" or Sleep of death. I won't say your case is unique, but no reason not to give it a go, right?
I had a similar issue with my 10.1v and the 10.1 3G , I ended up bricking my 3G and getting the 10.1v at a second hand price due to the very same reason. After draining them completely I had flashed both of them successfully and now like cancer free patients, they're both alive and kicking.
Edit: I forgot to add, this is normal, the device won't even pop up on Device Manager or the "Installing drivers" list until and unless you drop it to APX mode. If you did it right, You'll hear the USB sound.
Thank you for your post Misledz, it seems that someone has a new method which might work (I hoooooope so lol).
But could you explain me what you mean by APX mode and how to get into it? I don't really understand.
Plus I don't understand what you mean about drying the thing dry. Could you explain me that too?
Many many thanks ;-)
Edit : Ok, I finally found your tutorial and will test it, hoping this will work ;-) I keep informed.

Well glad you found your way to it :] The guide talks about how to drain it dry and get it to work :] In hopes it works!
??? I don't understand why but now I'm unable to turn on the Tab unless I plug the usb in??? (maybe she's feeling i'm about to fix it?lol)
It will be hard to drain it if I can't turn on and off without plugin' it. Any idea??
Edit : important thing : when I plug the usb, I have the battery charged to 100% and the Tab vibrates, so no, it's not because the battery is empty lol
Edit II : I'm not sure I fully understood the tutorial. My though is the following:
1, I drain the tab by holding the power button down.
2, I hold the power and vol+ buttons, plug the USB and maintain both buttons for 15s (could it be more?).
After that normally I should have a loop of pop up in the device manager for APX device, I release the vol+ button but keep power button hold and wait the end of the loop to install the nvflash driver?
Correct? 'cause if it is, it don't work for me :-S I can't have the pop up loop (I remember I had this loop once, but I released the power button and the loop cut and the "unknown device" disappeared from device manager. But since, I can't get this again)

I don't think your actually getting it The whole idea is to drain it or find an alternative way to get it to fastboot mode to bring it to Download Mode where you can flash an HC rom of choice to save it 140%. 100%..Wow that's not going to be easy to drain..
In fact, I don't know why, it seems it was kind of a bug because after that I unplugged and plugged the socket charger again and I had a battery icon why a exclamation mark and charging.
However, it seems you answered when I was posting "edit II" in my previous message. Did you read it?
Anyone having an idea?
Good luck with helping this one Misledz.
They don't know how to reinstall drivers in a windows machine if the device the drivers are for are not found
So this is might just be a fun endeavor. :screwy:
I think there are other issues needed resolved before this person roots or mods anything. Like understanding their Windows machine and how to install/reinstall drivers.
Always has just been running the install from the drivers file and accepting yes I want to install the drivers even though the are already installed. I could be missing something about this part as it pertains to this problem. But sure I'm not mistaken about how to install/reinstall drivers on a windows machine. Windows can't be expected to recognize every thing first, and then download and install the drivers for it. Maybe its me but that's what I'd call a fantasy world. I know thats what plug and play says it does. I also know that it often fails. So, needing to learn, I even know how to completely uninstall the possibly offending drivers before reinstalling said drivers, sorry I don't have the patience to help with this one, but when you goto the10.1v I can use that as my excuse since I don't own one.
Plus I don't want to follow you into the rabbit hole.
A sincere Best of luck to both of you. Misledz and the person with the problem. :thumbup:

sure, Just abandon me Q.Q
But anyways the driver for the device is in the samsung website, it's device specific.
In order for the device to be recognized you need to have the appropriate driver for it.
Another would be making sure that the tablet get's read on the computer via fastboot mode/adb. You need to use the Volume Down+Power option till the logo boots up.
Then again, what do you see when you boot up the tablet? / Can you even boot it? That would be a good start and more detailed info would be appreciated
PS- I just read your Edit II, turns out to get unknown device it's Power+Volume Down, which is the left button on the volume keys. You hold it down when it's plugged via USB to the PC for 15 secs, 20 seconds doesn't matter just it needs to cross the 15sec benchmark. Once you get past it forces itself into APX mode. This is where you need the APX driver for it. Seeing as to your tablet is unlocked you may be able to save it.
I edited my post after you quoted to try to explain my potition and reasoning reasons a little better. Good luck mate!
If you can read this it was sent using my GT-P7510.
Misledz :
The problem is that I don't find (after several researches) the drivers on samsung site, but I found another one.
The tablet is not recognized in ADB nor in fastboot (as told in my first message)
When I boot the tablet, I see the samsung logo with open padlock and then the boot animation with the android bot and then I'm stuck there.
When I hold power and left volume button, the device turns on and I see a screen with the usb and the droid in the triangle (downloading mode)
I think (by reading the very interesting post of benzoman) that it might have a confusion about "the device isn't recognized by the computer". What I mean is :
When i plug it via usb, turn it on normally, or put it in downloading mode or fastboot mode, the computer doesn't even react (any sound like when i plug a usb key nor pop up saying "new device detected" in the right bottom corner of the screen)
I hope these informations added to my first post are enough for you to have a clear vision of my problem.
Benzoman :
You don't have time to give the informations you "know", but enough to waste by writing this type of s**t?!
Can you tell me how does a cyclotron works? How we modulate the power of the exiting ray of particles? When you will be, just come back to waste your time here and show that you think you're smarter than others. Everyone has his own job, I'm not into computer science so yes, I recognize I'm far to know every thing, and I think that's the purpose of this type of forum : share knowledge and help others when needed.
I think you should open a new type of forum, if your entertainment is to waste your time by laughing at other's problem.
You wrote about 10 lines to say nothing...but don't have time to give a hand? How many lines would have been necessary to give a useful information? By seeing how strong you're saying you are, surely less!
At least, if you don't want to help, don't foul the topic, it will be easier for the ones who really want to help to follow!

Please do not quote this post as it is being edited constantly to futher help juxci and explain any misunderstandings and quoting it before completion will only cause more issues. Thanks for understanding.
First, I was trying to be polite by stepping back and letting Misledz help you. Having both of us suggesting conflicting ideas would have of been little help.
Second, if I did't understand the very basics of say, oh idk, maybe a cyclotron why would I mess with something that relies upon on it? I still would because there are others that can help, should something go wrong. Albeit, I would not DEMAND their help and would even understand if they chose not to help if I acted an a$$.
Then b!tch because someone tries to help me, and my response comes across like I know what I'm doing, but is really only being a rude reply of, "Can't do that." When the person trying to help knows it can be done, confirming I know not even the basics of the cyclotron and should be open to any and all help. Not act an a$$ by just saying, "That can't be done." When it can be done, and easily, if the person who knows about the cyclotron would tell me. But, since I want to be an a$$ and act like I know what can and can't be done on the cyclotron. The person who could have helped with it says, if I'm not going to listen, then they'd rather not be directly rude themselves, and get aggravated, notices another who has the knowledge is present, wishes them both an HONEST WISH OF LUCK and leaves.
This is basically what I myself was trying to do. I know the drivers can be completely be removed and reinstalled on the PC, but you acted an a$$ and said, that can't be done, sounding like you knew, what you were doing, and wasn't going to be open to accepting my help, without causing me great frustration in the process. So knowing that the very knowledgeable Misledz, was here to help, I thought it best to leave it up to him. My wish of luck was sincere, even if it was indirectly sarcastic.
I should stop here and not look back at the thread, but I have always tried to help where I can.
If you really would like my help personally. Here you go, I'll start again. Although it's repeating things Misledz has already said.
You need to get legitimate Samsung drivers which are specifically for YOUR device to install. Ones found elsewhere may cause more problems than they fix.
If installing the drivers over the top of the others doesn't help you need to uninstall the old drivers fully. Then install the official drivers. This has helped others and even myself once or twice. Widows is a finicky little [email protected] sometimes.
Uninstalling the old drivers completely may be considered complicated and without having another reference handy to help me guide you to a program, I can't do it correctly. I will have to get to my PC where I have access to use references for me to look at so I can help you best. I will be back to to check on the progress of your issue. ASAP
I think some of the problem may have initially been from my personal misunderstanding of your grammar. Believing you were stating things in a way you did not mean. If that is the case, I apologize.
Edit: http://www.nirsoft.net has a program called USBDeview. It is what I use to completely uninstall all Samsung drivers. I use it to find and remove all the drivers found referencing Samsung. CAUTION...this could cause even more issues than it solves if you remove the wrong drivers or you don't have the drivers specific to your device. I cannot say any specific driver is safe to remove without being able to see and know what they are there for.
Being that you're using a 10.1v Device and I only have personal experience with the 10.1 (no v after 10.1) I may lead you in the wrong direction. One of the reasons I was not going to help, as I stated in a previous post you took as offensive.
But if you wish to continue with my personal advice just post your progress and I'll post help when I can.
I honestly think Misledz would be of more help to you and I'm only going to get in the way trying to help. We're both saying basically the same things using different words.
Whatever the case, keep us updated.
D:...I was wondering what the fuss was about...and then the mega paragraph came Let's relax on this firstly, Jux , Benzo is just trying to help I do agree I end up suggesting the less problematic solution to drain but ofcourse there are other methods to "tame" this wild beast of a tablet. I've only been on the Galaxy Tab scene for less than a week so I'm just giving information based on experience , I hope you don't take to heart what he said, as this is a Q&A thread and almost 70~80% of the threads go unanswered that people purposely post in the development area for quick attention..only to be booted here by the mods (Which I agree they are doing a good job, Kudos), atleast on the positive side, there has been interaction in this.
Moving on to the main deal.
I know you have mentioned the droid and the triangle, but it confuses me as to do you stay in that screen or do you select an option. If memory serves me right, the left, being the droid logo (You select it with the (+) key, which is the right volume key, and navigate with the (-) and select the droid logo) I know you haven't been into download mode because you didn't mention the warning that it gives before you actually get into download mode.
Warning goes somewhere along the lines of proceeding at your own risk with a huge ass triangle telling you the following. In which you need to press the plus key again to confirm. If you did this right, no matter what, lack of driver or such, the PC will recognize the newly open port. Normally Odin won't recognize the tablet despite being in the fastboot menu, but adb will.
I would however suggest trying a different USB port? or another laptop? Normally this RARELY happens but some HP based desktops come with a built in MMC reader which consumes a port of it's own and conflicts with the port Odin requests. You don't really need a high end PC to get this done, just the required files.
And just for reference could you kindly state what OS are you on, Windows __? Seeing as to how you said you aren't that tech savy I would assume it's either Vista (Which has some HORRIBLE USB port management) , If it's XP , XP tends to reserve USB port's for previously plugged devices to avoid the recache or reinstallation of drivers.
I know the vast questions may sound silly, but trust me on this, the least expected situations are what causes the most frustrations
Note: I haven't worked in any Service Center's if ever you're wondering -.- so I do apologise if I sound like one of those Dell service reps.
My sentence was :
"Thank you for your help, but I still don't understand, and this is for every type of device, how can I install driver if the device is undetected by windows?? In the device manager, I don't see any unknown device or something equivalent"
I don't see what's not clear or what let you think that I meant "that can't be done"... Whatever, you made apologizes, I make mine too for the eventual misunderstanding between you and me and yes of course, your help is still welcome if you want to.
So, back to the main problem, I used usbdeview to uninstall all samsung drivers.
After that, I followed this tutorial to enter in fastboot : http://forum.xda-developers.com/showthread.php?t=1064793
That means I :
- Downloaded and install the JAVA SDK
- Downloaded the Android SDK
- Downloaded the USB drivers
- Edited the “<PATH TO ANDROID SDK>\extras\google\usb_driver\android_winusb.inf”
And then :
1) Power off your tablet
2) Hold the VOLUME DOWN button and press the POWER button (your tablet will power on and you will see the BACKUP and USB icons)
3) Use VOLUME DOWN to select the USB icon, and then press VOLUME UP to confirm the selection.
4) You should now be in fastboot mode (the word FASTBOOT should appear somewhere in the top left corner)
5) If Windows doesn’t automatically detect the device, go to device manager and find the ‘Fastboot’ device. Right-click and select update driver, choose to manually install and browse to the “<PATH TO ANDROID SDK>\extras\google\usb_driver\” folder.
And there is the problem : any sound when I plug the tablet, windows doesn't detect automatically, so I go to the device manager to look for the "fastboot device" (or another type of device that is not from the computer) and I don't see nothing...so I can't update drivers.
So that is why I asked the question : How can i install drivers if the computer doesn't see the device?
After that, I tried all the things you can read in my first post because I wanted to be as complete as I could in my description so you can have all in your hand to give your advice.
*Cough* before It goes un-noticed my suggestion got blocked by your reply

Firstly, NEVER, ever, ever, ever use titles like "please help" and nothing else. Its extremely annoying for many people so you have less chance of getting a accurate answer. Use proper titles that describe the topic, titles are supposed to be descriptive, not simply somebody saying "help", that doesn't describe your topic to people browsing sections in any way other then its a n00b panicking about something.
Second, which model/variant do you have?
Which rom did you try and install?
Which guide did you use?
What EXACTLY did you do?
You need to provide more info if you expect answers/help.
At this moment people can only tell you to enter download mode and flash back to stock via odin.
If you don't know what download mode or odin is then you simply should not have been flashing your device as you obviously haven't read anything properly.
ok I am sorry and you are right... well i downloaded an ics from a site (can't remember) and i tryed to install ... first 2-3 times i got some fails in odin... then i closed and restarted it and it worked... at last for some mins... it blocked at ''setup conection'' step. after a while i closed the phone and odin and when i tryed to open the phone appeared a phone,a computer and a dot line with an ''!'' mark on it. now if i try to put it into download mode ( vol.down + home+power ) gives me same thing with that image and also with vol.up+home+power so this means i cant do anything with my phone...can't open,can't put it into download mode,and also cant restore to factory settings

This is what you get when you read and use instructions from some random crappy/sites or blogs or you dont read instructions properly, flash wrong files to your phone etc etc.
Remove battery for 10-15 mins and then replace, see if you can get into download or recovery.
If not buy or make a USB Jig and use that to see if you can get into download.
If not you will need to do/get a JTAG repair or send to Samsung and play dumb about what you have done, Just say you was using Kies and it failed or somthing, Hopefully they will repair.

well i downloaded an ics from a site (can't remember) well thats helpful to know lol
after a while i closed the phone and odin and when i tryed to open the phone appeared a phone,a computer and a dot line with an ''!'' mark on it. now this has killed your phone why oh why did you not read prior to trying this
i cant do anything with my phone...can't open,can't put it into download mode,and also cant restore to factory settings so basically you now have a expensive paper weight u may need JTAG repair not sure if jig would work??
shame really s2 a really good phone lol
You still haven't said which model you have. It's on the label under the battery.
And the pc - ! - phone screen is a forced download mode. You should be able to flash from there as long as your computer detects the phone from Odin.
solved

Work on reading instructions (and in general, really... You PMed me despite my signature requesting no tech support PMs) more thoroughly. You were asked multiple times what model phone you have, and never answered. If you had provided that information, someone could have directed you to that guide faster.
And if you successfully used that guide (which implies you have an i9100g, and NOT an i9100), then stick to i9100g firmwares and kernels. If you DO indeed have an i9100g, and flash i9100 firmwares or kernels, you'll end up back in the same boat.
