jam dead after firmware upgrade..please advise - JAM, MDA Compact, S100 Software Upgrading

k my buddy wanted to update the firmware on his 850mhz 128mb jam...now it wont turn on...not sure how he did it or what he did...but is there a chance he can save it?
any advice would be great
thanks

There has been a lot of confusion as to what people consider to be a dead device...
If you can see any of the bootloader text then yes it can be saved- by reflashing.
If you have a total black screen- nothing on there whatsoever then from personal experience, there is nothing you can do to recover it (by yourself anyway).
The same thing happened to me when I was applying the BigStorage. Tried everything, including leaving out the battery for 48 hours.
Had to return it to the service/repair centre. As of yet there is no bootloader 'repairer' for the Magician.

Flashing will kill your phone!!

Hi, help please. I been using these new builds and working very well, but now I just get 'The SIM card is missing', I have tried other SIM cards with the same message!.. please help
thanks
Help Help Help, please any ideas, my phone is still stuck on sim card missing!
have you tryed reflashing it with different rom?
Yes, flashed with 3 ROM's and also flashed with RADIO's ROM's, but still the same.
This phone is getting worse, with no phone working I still use it for TOMTOM, but now no sound or patchie sounds, music or phone sounds, I flash it back to WM5 still same and flash it back to WM6 but still no sound. Is there anyway to completey delete the phone so nothing on it then flash it.
Maybe it's because you've got an hardware problem ... so maybe you should see your "service after sale" !!
I would if it was still in contract, so I am thinking about taking the thing apart, and see if anything come loose?. any info would be nice, tried searching but nothing
This phone is very sick, if i put a SIM card in it I get a blank screen when it reboots, or if I take SIM out I may get the blank screen which I have to reset couple of times, took the back off but cannot see any connector off. So I have to pay alot of money to fix it or buy another PDA.

My only question is: What changed?
Is there something that you can think of that caused this to occur?
Have you dropped or bumped the phone? Liquid got to it? Charging when the power died or there was a lightning strike?
Without knowing this, there is very little that can be done.
As for pulling the device apart - I would recommend against this. Complex electronics like these have no user-serviceable parts, the most you can do is to look for physical damage (such as burnt components or broken legs on chips) or water damage. And then, even if you did find the damage, you would be able to do very little with it as the components can be hard to find (for any of the chips) and the soldering is extremely difficult (my father hand solders surface-mount components using special liquid-solder and a microscope).
If you want to repair it, find your nearest HTC (or I-Mate\Dopod\O2\etc) repair centre and give it to them. Keep in mind that you've already voided the warranty by installing a custom ROM (although you can just install the manufacturer's ROM and pretend you never used WM6...).
Hope this helps!
I use it every day with TOMTOM or I-go (lorry driver),so getting knock's vibration-yes. camera stop working and green went green-but after a couple of weeks it when back normal. never failed on flashing or stuck on bootmode. NO SIM started I just reset it then it was ok until next time. Then it went back normal for a couple of weeks, then NO SIM came on and couple more things happen(above posts). And that how it stands. So 12 months gone a passed (18 month contract). So its sent it to O2( big bill I think) or buy a PDA (cheap I hope). Or wait and see for upgrade brings
Update on my EXEC, It starts as followed, O2 screen comes up with it info at bottom right then the next screen is the windows mobile6 screen and then black screen, tryed mtty, also re flashed it....now its dead R.I.P...
I think I flashed it too many times so be warned!!!!
Been looking at other PDA phones, none of them comes near EXEC will apart from AMEO(thats nice but too much), so looks like another EXEC I think, and yes I will be flashing that one as well if I get O2 to part with one.
Hi, all tryed to get a new EXEC from O2, but sady they say they dont do it no more, so upgraded to the ORBIT( or should I say down graded). SO I like to say bye bye and watch that flashing because it will kill your phone.

Little Emergence

ok im not that new to flashing i have flashed about 6 or 7 roms on my phone in the past. today i was running dutty's V4 and i have been running it since it came out to the public and today i went to read a txt message and the phone blacks out and i get a red light at the top but its only there when the phone is on a charger. i can not restart the phone at all.
dont know if it helps but i was running Dutty V4 with cube enabled also running s2u2 and thats about it as far as stuff that was running other than the rom itself. i really hope there is a fix to this. i have already tried to reflash but device is not found.
well crap... i hear the red light be nicknamed the red light of death... i hope to god there is a way around this... if not would att know i reflashed something else if i went in and started to complain?
i had a similar thing with my orange uk keiser and i just got orange to ghange it for a new one. that was over a month ago now and i have had no questions so far. if you cant get it to work then they cant either

Have you tried to put it in Boot Loader mode? Can you do a hard re-set?
As posted above, this is referred to as "red light of death" - RLoD.
Rzanology had a potential fix for this involving removing battery cover and pumping battery up and down on battery contacts (battery cpr), that appeared to work for some folks - tried to find the thread but was unsuccessful. You might try pm'ing him.
If you are unable to resuscitate your device, most have simply returned it. Good luck!
apologies for the hijack (and sorry to hear that you're having problems) but I've always wondered what they check when you send it back for a fault repair.
Just wondering how many people have sent back their phones with hardSPL and custom roms still installed
well if it totally dead don't worry about sending it back with custom things flashed to it. most of the time they just hook it up to a charger and see if it will turn on and if not throw it in a bin of other messed up kaisers. I'm sure HTC knows about the red light of death and what makes it happen.
no biggie on the hijack
well im stil standing in att but obviously since im sending this I got a new phone. they tried to give me a loaner until they sent mine for repairs but when they offered me a 89.00 phone I laughed and told them my kaiser is worth more as a paer weight and that I run my bar from my phone and that their loaner wouldn't cut it. they then offered my an iPhone to replace it, telling me its a beter phone anyhow so I went to the magazine stand across the isle and showed the a mobile power magizine that has the tilt listed higher and also told them that I needed my 3g internet and also said look if ur willing to give me an IPhone why not a tilt. after about 10 mins talking to me I got my new tilt.
now omg I can not wait to get the htc today screen back and opera. ie sucks

apperently I dotn have trouble bricking one so just pretend ur me...but tbh if u want to brick it completely I would just replace the fuse in ur car charger with a much higher one and crank juice into the phone... but don't put too much into it burn chipsets smell horrible.
the microwave for 1 minute does wonders for bricking phones not that I would know that for fact though

Not the old microwave trick - wasn't it you who posted this in Hermes thread a few months ago?
Phone insurance which covers "accidental" damage is a good move, although you will probably need to pay a small excess. I managed to push the usb port inside my universal a couple of years ago and got a straight swap. If you dropped it (from a height onto a concrete floor) I'm sure no one would even try to turn it on. Alternatively have a run in with a stranger in a hoody on a dark night, get a crime number and no one will even have your phone to check for HardSPL or custom roms

As mentioned in the other thread (no I'm not going to search for it. ) the only thing AT&T cares about is if the water sensor has been tripped (little white square under the battery permanently changes color when wet), or if there is obvious physical damage/abuse. Apparently they can't get past the RLoD either. As an aside I'd really love to know what the RLoD return rate is...
So, given those constraints the other thread's conclusion was that 12v across the battery/charge contacts should permanently brick it quite nicely. Just watch out for arcing.
THERE IS NO EVIDENCE THAT THE FLASH IMAGE AT THE TIME HAS ANYTHING TO DO WITH THE RLoD. It appears to be a hardware problem, and no-one here has reported an issue with a returned RLoD Tilt or Kaiser with a 3rd party flash image loaded.
In my case I also had to wait a few days to get the replacement units unlock code because apparently the IMEI was so new it wasn't in the database according to the service drone. Which suggests that AT&T is using a table of unlock codes from HTC rather than a piece of software to generate the codes. Now that we have an unlocker and "Super CID" program available, it's moot anyway. (Good karma wishes jockyw2001!)

My Tilt hasn't gotten messed up yet. But I have return 2 8125's and 1 8525 back in the days and I sent them back with custom roms. AT&T never complain or anything like that.
My bad, it wasn't Rzanology, it was sWuRv (that avatar freaks me out).

Fully bricked Captivate? Please, help! Tried many things..

Hi everyone,
Here's my problem :
Since some few days, my Captivate won't start up, and won't connect anymore.
The screen stays black!
I tried usually things : removing battery,sim,microsd, then pressing vol up, down and power, connecting with ODIN3.. Nothing happends.
It was bricked after a custom ROM update. I did format data, cache and .. system ! As usually, because I tought formatting system was necessary. Maybe it was the wrong thing that made it crashes..
So, I thank you a lot for bringing me any help !!

could you give pls a little detail. as to what custom rom did you flashed, is it the froyo rom or ginger rom? and elaborate further on what did you do when this happens it might give other people here some more understanding on how to help you. If your your phone won't power at all and the soft bottons won't light up and won't respond with key combos or even a jig you likely had a perma brick as in hard brick.!!......If you are still on warranty no worries just tell them that your phone suddenly dies and that you have no clue what happens to it.
You can also try this if you like read the thread: http://forum.xda-developers.com/showthread.php?t=1020976&page=3
Thanks for your answer!
I flash many of my phones, so, unfortunately, I can't remember what kind of ROM it was! I also try many of those I can find on XDA.
Here's what happens :
Had formatted data,cache, and system. Then, flashed the ROM, and selected "reboot". Just after that, I was making coffee.. So, I came back 5 min after, and the phone was .. dead!
After many, many, many Captivate's ROM flashes (maybe 70 !?), first time it happends!
The phone is no more under warranty, so I can't do anything..
Btw, what is a "jig" ? Heard alot that word but..
And thanks for the thread, but I don't think there's a solution in it!?
I will browse it tomorrow, thanks

The jig is usually the last resort for some. That is if holding volume up and volume down then plugging in the usb cable into your phone ( the other end being already plugged into your computer) does not put it into download mode.

U can either buy a jig from someone like mobiletechvideos on YouTube or make one urself using resistors (tutorials are scattered around the forum). U plug it into ur micro USB slot and it will put ur phone onto download mode. This works if ur phone is soft bricked and it may not work for u but definitely worth a try
Sent from my SGH-I897 using XDA Premium App
Sounds like you flashed a single bootloader and hard bricked your phone. Either jtag it or buy a new one...
JIG2WIN4LIFE if you can still turn on your phone without a perma black screen anyways
Hi,
I took a look over "JIG" on eBay, and found it for approx. 8 $.
But it says it can be used for ALL cases, at the exception if the screen stays black ! And that's my case..
So, do I have to buy it anyway, or is it really dead?
I don't want to buy another one!
Thank you.
sometimes the jig works, if you take out battery, DO NOT TOUCH ANY BUTTONS, put in jig. worked for me.
BUT your phone is under 1 year old. it has a warranty. if it happens to get broken in a way that they cant tell, and can never read the phone again... you get a [email protected]!!!
think speaker magnet or
2 seconds in the microwave 1 or 2 times MAX.. dont want phisical dammage! and there is plenty of electronic parts to get messed up very easy this way

Wow, nuking it will cover your tracks if they try to access anything on it?
if it is electrically damaged and wont work, they cant access it, and they cant see your tracks...
and my buddy nuked a phone before, to destroy it for fun, there were sparks immediatly. if that happens the phone aint going to work anymore. so do it in very short bursts. you do not want any physical damage.
or wave it in-front of a LARGE magnet to degause it until it doesnt boot anymore.
Hi,
Thanks for your reply, but my phone is no more under warranty..
There was no warranty when I bought it from USA (on eBay), and I'm living in Belgium! So, no way
I will have to try the JIG then.. I suppose it's my last chance
yup jig is your last chance..
now the other day i bricked and the jig wouldnt work either unitl I found a trick that helped my jig work. this worked FOR ME in my situation. not all.
remove battery count to 5 and replace battery
DO NOT TOUCH ANY BUTTONS
put in jig. download mode!!!!
if i touched ANY button the jig would not work. worth a shot.
jigs are about 8$ on ebay or can be made with a few resistors for a couple dollars. (or whatever currency you have in Belgium). there are many threads on how to make them in the captivate forums on xda here. just make sure not to touch the resistors with your fingers if you make one. use tape to hold it.!! good luck buddy!
Thanks a lot!
I will buy a JIG on eBay then.. It would be safer!
We are using Euro currency in Belgium . So, a JIG is approximately 6 €.
It's a cheap price for this kind of tool! But by the way, HTC has much more solutions to unbrick their devices..

[Q] Hard Bricked? Sidekick 4g

Soo I have a big problem,
My sidekick 4g suddenly shut off and directly went into Download Bootloader. It would only stay in that window for about 3 seconds then restart. So I tried doing Odin but it would never stay in download mode long enough. After a while, the phone stopped turning on and now it does not even charge. I believe I have hard bricked the phone. When I leave it on the charger. I see no indication that it is charging but the battery gets warm. Is there any hope for me to fix this phone?
Please let me know ASAP. Thanks!

Does the device even show up as a USB vendor/product id? See that with `lsusb` on Linux or the Device Manager on Windows.
It might be worth trying ayoteddy's FOOL PROOF WAY TO GET INTO DOWNLOAD MODE here:
http://forum.xda-developers.com/showthread.php?t=1186954
Perhaps if you trigger the phone to enter download mode that way, it won't just continually reboot...
Beyond that, I think you'll be looking at hardware-level fixes. If the phone isn't literally fried, it can almost certainly be repaired with JTAG. But that would involve a JTAG interface which I am guessing you don't already have.
You might be able to find someone who will JTAG for you for free, or for a fee. A local phone repair shop might have this capability.
If you're damn good with a soldering iron, or have a friend who is, there's also AdamOutler's "UnbrickableMod":
http://forum.xda-developers.com/showthread.php?t=1347984
That mod is not for the feint of heart, you need to take the phone almost entirely apart and do soldering work within the area of a grain of rice... but it is possible.
But all the options assume that the only problem with the device is a bad flash -- damaged boot loader, bad kernel/recovery, etc. The way you describe your phone's demise, a hardware failure certainly seems like a possibility.
Good luck, I hope your device is not dead.
FWIW, SK4G goes for ~$100-200 on eBay these days depending on condition. Locally you could probably find lower prices.
Wow thanks for all the info but i tried ayoteddy. Since the phone doesnt even power on , i cant do what teddy says. And no, after a few failed odins, the comp doesn't even see the phone. But that's also because the phone doesn't turn on. I even put a charged bat. Still no go

It really sounds like a hardware failure.
If you are committed to trying everything to rescue your particular device, you could double down and try a new battery. You risk wasting whatever money you spend on it, of course.
If I recall correctly, the SK4G can't operate properly without some battery current, even when plugged into USB. And the other symptoms seem to leave the door open on battery problems -- sudden power down, brief signs of life which eventually cease, hot battery. The sudden failure of a lithium battery would hardly be unusual.
I have seen an issue very similar to this before. It turned out to be a loose connection inside the phone. Might want to disassemble and reassemble carefully to ensure that the connections are secure. Youtube has dis-assembly videos to guide you. You don't have to completely disassemble the phone, just til you reach the main board and secure the connections to it. If you don't feel like you can hand the task of dis-assembly you could always search for a local phone repair business, or even computer repair shop (they often do some phone repairs). Hope this helps
Hey there, I am trying to fix a SK4G with the exact same problems... download mode will show up, but then the screen will go blank again. I'm gonna look into what blk2dr suggested... did you ever fix yours, OP?
root? so Warranty it, not saying its the most "ethical way"
out of curiosity what was the last, well as samsung would put it, hac...ERRRR unsupported warranty voiding modification known to us as upgrade/flash eg. via cwm odin rom app add on modem kernel etc. that was done to the ol SK? or is it just straight up faulty craftsmanship from samsung...nooooo on a SK4g??? is that possible? lol moving a rom around from folder to root of sd once (zip prev passed md5 check) my 2nd or was it 3rd t839 had a lil hiccup that i didnt realize at the time made my custom Roms zip like 47kb smaller then it previously was and should of been, when flashing is 2nd nature and ur just moving it within the same sd card its already checked out on the md5 sum and ur dealing with a 200+/-mb file, whos gonna notice that minor change? to make a really long story just kinda long, into voodoo cwm flash, let it marinate... phone ran great for 4 days, then i decided i was going to clear cache davlik fix permish and reboot...yea went into cwm wiped wiped and half way thru fix permish phone crashed rebooted back into recov, when i tried to reboot sys it had your same exact issue. DL mode for just a second...then all black yet slightly backlit screen. could never get it to stay long enuff to odin back to stock, fullproof DL mode was a no go and of course the battery died, wouldnt recharge. i played dumb went to tmo store dude tesed phone with new batt my batt in other sk etc etc...anyways he charged my battery up enuff it flared back into dl mode for a few sec...my fix? hours and days headin into weeks of jackin with this thing i went with my cure all root REUPwarranty fix...flash a bad freakin bootloader thru odin and kill it once ad for all, DL mode only needs to be on about 4 sec, not long enough to go back to stock rom but long enuff to kill that B. prefered bootloader is i9000 haha works like a champ everytime to every rooted phone that had issues i needed a warranty exchange on(only been 4) seeing how i get a new phone every 3months on avg and always pay full price the ratio is tiny. yeah i know the trickle down effect raising costs from manufacture in long run yadayada. all is true, but i figure ive been kicked in the groin so many times by samsung,lg,moto,htc etc they can eat 1 every now and then. as a tmo employee in 07/08 i paid 500 upfront for the mda that got back ordered for 6 months had 2 bad dead spots in the touch screen within a month and screen went completely white in 3mnths. some employee/warranty fine print screwed me out of a new phone. and dont even get me started on the sidekick. 399 bucks for a phone that basically got abandoned 3 months later cuz it was junk compared to what it should be and breaks in high quanities. theyll still tax u 20 bucks and make u keep ur old battery and cover charger etc so im not losin any sleep, for real kill it for good, run it to the store get ur new err rebuilt refurb SK4g in 2 days then save up for a t989 s2 dl gmote/spashtop and poweramp on ur SK4g and let her roll as a wireless keyboard/mousepad for ur pc and let the voodoo and Pamp rock as a killer mp3 player. thats all the T-urd-839 is really good for anyways, oh yea and a mediocre bt controller for playin games on my S2's lol do the warranty, its samsung/TMOs fault for lettin this junk product get released, abandoning it and overcharging so many of us. Just do it, do it lol
pull battery, connect usb, hold power, volume up, volume down, camera, and tackpad and insert battery. It should FORCE the phone into download mode.
try it lol~

Death of my S7 edge and warranty

Hi, this is not exactly question, so I post into discussion, I want just your opinion... or if somenthing like this happened to you:
It started by simple restarting, or random vibrating from time to time. I just thought its some ROM related bug becouse I didnt update it for about 2 months, maybe something got messy. But I had some work to do and told myself it can wait few days. Then some strange freezes occured with vertical or horizontal strips made of small colourful dots. Only hard reset holding all buttons helped. Freezes, restarts etc. then continued quite frequently. This was time for clean rom installation. I went to TWRP, wiped everything except external SD. Done. I was going to hit install in twrp when freeze occured last time and after long continuous vibration it was gone. Now it does not react toabsolutely anything, holding all buttons - nothing. Connecting to charger - nothing, no icon, no charging indicator. Connecting to PC - nothing, it dont even notice connection of new hardware, Odin also sees nothing... It seem to be as dead as possible.
But this situation seems very good to me after all, becouse phone was rooted, knox tripped. They would never repair it for free if it was freezing, restarting or bugging screen becouse my warranty was gone by rooting long time ago... But now they will have hard time to get into Download mode or connect it to anything to see my voided warranty, or fact there is no ROM at all becouse it got broken right after last TWRP wipe. I might be able to come out of this with new S8 for 100€ (price difference between S7 edge and classic S8 in shop where I bought it).
What do you think? Will they tear it apart and find out about knox etc., or they will not go so deep when its completly dead and there are no physical marks of even using that phone? Have no idea how deep is their analysis and if they will try to change motherboard or just trash it giving me new one or money...
Any experiences with samsung repair service?
PS: sry for my grammar, had only 4 years of english classes at high school, not using it until then (only in forums like this)
Usually the guys at service station don't bother to go in download mode to check the tripped know it depends on countries to countries in most of the countries people got their phone repaired even though there phone was knox tripped and rooted
I hope they fix your phone for free as the service guys are lazy they'll probably tell that your SOC is fried and would recommend changing the SOC
thx for reply... true, they dont bother in my country very much at service ... they already changed my camera lens becouse left corner was always blury and no problem with knox tripped, but it was clearly HW problem on their side which appeared even on first photo, I just didnt notice it and rooted it first week of S7 launch... this also was not caused by root, but if they somehow find out they could use it as excuse, so i hope they will not try hard with software examination when its HW problem again
Just want to add to the list.My previous device (xperia z2 which goes to the same service center here in Bosnia) ,they never searched if i had custom rom installed.They just fixed it by changing motherboard.Please let us all know what will happen when you return your device to them.I think there is no way they can find out what you did to that device or if it is knox tripped.
Ok, I will report results here. It should be fixed in two weeks, max one month (or not if they find out about root, but I also think they will not)
Got my repaired phone back. With new motherboard and 0x0 original knox etc. Old motherboard was compleatly dead with all root info with it... Everything works now
