okay so i have spent many hours with my new motorola photon 4g that i recently got from sprint. bout 4 days now. im more use to using samsung android devices and htc devices and this is my first motorola. i had been wanting to root it because its my favorite thing with an android when i get one. so i did research and unlocked my bootloader and did the unlock sbf file and installed clockwork mod revocovery as well. after all that my photon was working fine but was on stock rom. i had downloaded a rom and put it into the phone and of course installed it. im not used to motorola and it was my first time learning about their bootstrap and blah blah blah. after installing i had tried turning the phone on but it just stayed at the Motorola dual core screen. i tried booting three more times to no luck. so then i had tried another rom and again i had no luck. i should have done the smart thing which is after the unlocking and putting on recovery to make a back up immediately but for some reason didnt. so i go online to find another sbf file so that i could start all over and see my mistakes, but then my battery was way to low. my advice to you is to make sure your battery is filled up cuz trust me this was a ***** to figure all out. so this is what i did in case if any body has this kind of problem, cuz i know im not gonna be the first, well maybe, but definitely not the last. what i found out is the phone wont let you flash any files when battery is low. and as i can say, its for saftey reason cuz if it dies while flashing, well you might be **** out of luck. depending on what you are flashing. but what i found out is that if you connect the hone to the wall outlet, the phone will turn on into clockwork. dont try plugging into the computer cuz it will be useless. i tried several times till i finally got the message. the recovery is the only thing that can be booted up. you dont even need the battery in the photon. it will still turn on as long as it was in the outlet. i then transfered files to the sdcard from another phone, over and over till finding the right one, then flashed and flaseh. finally, finally found a rom that woul work with ,y phone. i kept the rom till i was able to charge the phone. rom kept bootlooping but it kept bootlooping long enough to charge the battery then flashed the sbf sprint file to my phone. i wanted to write this cuz i was hoping somebody would be able to explain to me what i may have done wrong with the flashing or if their was a step that i had skipped cuz it seems like no rom works as of now with my photon. hopefully someone can help me out here cuz i really do want a custom rom. or maybe someone can tell me what i should do in order to install a custom rom and have it work for me.

jokersax11 has done an amazing job bringing ICS to the photon... I believe he will soon have his beta officially picked up by cyanogenmod... also, I am pretty sure he's close to fixing the 4G that you loose when you unlock the bootloader.
ok so i have a samsung admire from metro pcs CDMA i put cwm v5 on it and i formatted everything cuz it was bricked so now i have a samsung admire with no os cuz i deleted th /system /data and everything else you can think of so now what????
I think what you're going to have to do is use a piece of software called Odin and push the OS onto the phone via USB. Since you can't plug your phone into the computer and just drag and drop a ROM onto the SD card (since you have no OS) this is probably your best bet. Look to see if you can use Odin with your phone.
yeah i can you use odin i dont know were to find the os and i used odin to get clockwork recovery on my phone
Hey, I found this forum for you regarding the samsung admire, it might help they provide the stock rom and rooted rom for your phone aswell as instructions using odin.

o and one question i would like to become a dev. so hows that going to happen
Hi all
Im a newbie (and a noob by the looks of it)
Based in the UK and own a S2 which has 02 firmware but is unlocked
Connected to Kies last night to update to ICS
They go and brick my phone
My question?
How do I get my S2 back up and running?
At this point I dont really mind what it is running but would prefer ICS
I have ODIN Downloded but I am not sure how to get the ROMS/Firmware
Unzip/Zip the file
And how to get it on my phone
It currently goes into the boot mode when you hold Vol Down/Power & Home key
When powered on it comes up with load emergency jargon and connect to Kies which I have done numerous times to no avail
Any help would be appreciated ;-)
Rooted?
Is the phone rooted? I've never used odin. I have used Heimdall, which is pretty much the same.
Its not rooted
Just want to get it up and running asap
Any suggestions
Here's links for branded and unbranded official firmwares.
Unbranded firmware
Branded firmware
Those threads very clearly explain what you need to do to flash official firmware using Odin. Once you've done that you should be up and running again and can take it from there.
Thanks ever so much
I have a hour free now so wish me luck ;-)
Will report back and let you know how things went
OK Rather confused
All of the info is posted as you have stated but which one do I need to do?
Their are so many their and I dont get this whole root thing!?Do I need to root first?
Or do I not root as their is no need?
No root required to flash the stock firmware.
Sent from my Incredible using XDA
I've gotten my GT-I9100 bricked.
Had successfully flashed Resurrection Remix ICS v2.1 ROM along with SiyahKernel v3.3.1. Everything was working fine until some suicidal impulse gripped me to format the SD card from the settings.
The phone did so, 'said restarting device', and then only the Galaxy S2 logo would appear followed by a back screen; which would flicker now and then.
It refuses to load into recovery mode; I have yet to administer the jig.
Any suggestions on how I might be able to get the phone to boot into recovery mode would be extremely appreciated.
Thanking you for your time.
First up. I'm low on battery - some 40% on the optimistic side, so I'm going to avoid trying stuff on my own till someone helps.
It's a SOFT- brick, stuck at M logo :/ and looping restarts. All was well till I went ahead and tried 1% battery mod theming (on the stock odexed ROM - though I wiped cache ) :banghead:
The device is an Indian A 2 w/o 4G ?? Never saw the 4G option under network settings. Nor did the box advertise it. Could be wrong here.
Came with 2.3.6 Stock.
I've managed to pull up a link on the 2.3.5 Edison AT&T FXZ files.. but that's simply not the same phone as mine ( I think the radios differ.. could be wrong ) Also since I'm on 2.3.6 , I suppose I'll be required to edit some XML and overwrite some files?
I also have a 30 day replacement warranty with the online store I bought it from , and as seeing that I have NOT replaced the underlying OS as YET ( albeit a stupid 1% battery mod that didn't work out) , would it warrant an exchange ?
Side note : I DON'T have CWM on boot, but DO have a CWM backup of the stock ROM ( made one last night, though I don't see how it can help me now )
QUESTION :
* Is there any way my CWM backup can help if my phone boot loops ?
* Can an AT&T 4G radio goof up my Indian phone that makes no mention of it's HSDPA+ radio ANYWHERE ( other than the 21MBPs ?? ) .. Here's the link to the product page.
* I can always hope for the 30 day replacement warranty to do it's thing, but in my country, Moto service is sub par. Worth it ?
* Should I give moto-fastboot flash system system.img this a shot with the FXZ I'm downloading right now despite the 2.3.5 and 2.3.6 mismatch ?
This is my first android phone and despite reading up a bit on everything, I messed with a stock odexed ROM , so spare the noobness
The first thing you want to do is pull the battery. At your state, the only way to recover is to use (moto)fastboot or flash with RSD Lite.
I am not sure if the radios are the same. After reading the reviews it seems that it does, however I wouldn't take any chances. There are two things you can do:
1) Flash the fxz. By default the fxz will flash a lot of partitions including the radio, so you will have to edit the file "InlineFlashing_edison_5.5.175.16_cfc_p3_APBP_CID285.xml" that is inside of the fxz to just flash the system.img
2) Use (moto)fastboot to flash the system.img. This is much easier so long as you know how. This is the first thing you should try. You can try "(moto)fastboot flash system.img" on its own but you might get an error about unable to write to /system. I recommend that you try these commands:
Code:
fastboot flash mbm allow-mbmloader-flashing-mbm.bin
fastboot reboot-bootloader
fastboot flash mbmloader mbmloader.bin
fastboot flash mbm mbm.bin
fastboot reboot-bootloader
fastboot -w
fastboot flash system system.img
Good luck!
Thanks a lot for the help. I contacted the store and they're giving me two options :
1.Replacement --- Well, it's out of stock, so this is shot.
2.Cash-back/ Credit ---- I could always wait on a new intruging phone. Though I doubt I could find something as cheap and powerful other than the sensation (know what you're thinking).
^ The whole process could take about 2 weeks to get me a new phone. Lame.
If you're absolutely sure about the flashing AT&T's FXZ files, I don't think I'll wait for that refund. Rather like this phone. I hope you've taken into consideration that :
* I'm on 2.3.6 stock odexed.
* I'm NOT from the States. Radios could differ.
* Once I do this and if it doesn't work , there's absolutely NO way that MOTO will take my phone back. Pretty sure the OS will look tampered with. Anyway , there's no service centre in my vicinity.
* If i flash the system image as you mentioned, isn't everything inter-linked in the OS package?? I mean, how can the AT&T modules work with any odd radio?
Thanks again!
Did you already try holding volume up + power when booting, then when you get to a screen with the android and an exclamation point inside a triangle pressing VOL UP + DOWN at same time to factory reset?

Ok I am from India, I was in the same scenario you were in, the FXZ on this forum WILL NOT help, Indian ATRIX 2.
What I did, simply barged in MOTOROLA SERVICE CENTRE (Local to your city) and told them, i was doing a software upgrade (OTA) and the it hung, so I removed the battery and this issue started.
The person in the service center responded Quote: " That is what you should not be doing, when you do OTA update"
He then re flashed the whole phone to stock 2.3.6, as they would be having Indian FXZ and gave back my phone in 30 min.
I am now on Victory ROM and still enjoying flash MOD and ROMS, the lesson I learned is, do not flash any MOD unless it is working and confirmed from others ( provided you do it right way)
So go to service center, and your issue will be solved.

Well, I always knew I could do that. Have been messing around with moto and RSD from the L6/L7 days
There's no service center close to my place. That's the only problem. I wish there was one.
Questions :
* anyway they would give me the FXZ files ?? I could beg :/ If anything , I'd be doing a LOT of people favors
* You're using CWM on boot ? is it ? Cause I didn't and I suppose that was simply asking for it . Also, ROM manager flshes recovery for a LOT of Moto phones.. Could I get by, by using the Atrix 4G recovery or something similar. Whats the worst that could happen ? Soft brick or hard ?

Dont worry, I am an Indian user, been in this situation. All I did was, took a chance. I flashed 2.3.5 Stock AT&T FXZ to my Indian Atrix 2 using the script given here on XDA and it came to life within few minutes. Hardware on Indian Atrix 2 and US device are exactly the same.
Just install AT&T FXZ, root it using 2.3.5 one click, then install bootstrap recovery and restore your previous backup and you will have exact working phone back in your hands, I did exactly the same and mine is up and running, no radio issues or anything at all.
The only stupid thing I did was, I took backup of Indian ROM after deleting some system files, which makes my phone's messaging app force close everytime I receive a message. Once you get yours up and running, would you be kind enough to upload your clean CWM Backup (or take a new one, after you fix it, if previous one has your personal stuff) and upload it to dropbox or some file sharing site?? It can help me fix my messaging issue too. And since Indian firmware is not restrictive like AT&T rom I beleive some Devs here can use it to make a fantastic overclocked rom, been looking for that since day one, all custom ones are AT&T based, so restrcitive.
Good luck....

The one I used was from this thread http://forum.xda-developers.com/showthread.php?t=1539167
Its a script, you just need to connect your phone in fastboot mode (Vol Up+Vol Down pressed together and power on, select Fastboot from 4 options), and then click on bat file (Its name is something like return to stock.bat or something, dont remember exactly now). Then just wait for few around 8-10 minutes and it will do everything automatically and you will have your phone working in no time
Thanks for that info , but ..

As you can see , well, the problem is flashing these files to a 2.3.6 device. :/
Anyway the store has offered a refund so I'm hopping on the bandwagon and biding out my time .
Here's what I plan to do :
See if I can somehow score a ONE S at a reasonable price else I'm just going to buy this phone again a month from now, at a more respectable street price. I'm judging ~ 21K and no more for this phone a month from now with the S advance et all releasing soon enough. 22.5K is simply too steep with ONLY ONE service center in my state :/ WTH :/
IN USD speak , that's ~ 400$ unlocked compared to the ~ 450 I bought one for a week back. I know that's cheap , but we pay in whole, no contracts for us, so the pinch is bad
This is what the service center rep had to say to me :
ASK MOTO FOR THE FXZ FILES :/ ( why they don't already have the boot files on an 8 month old phone is beyond me )
And MOTO customer support asked me to hard reset .. as if I didn't already try. They're asking me to goto the service center that hasn't and FXZ files :/
And the next cloese center is about ~ 80 Miles away and their registered phones are out of service :/ The next closest service center is about ~ 200 Miles away and I'm done hoping that they'd fare any better
Side : I plan to upload my CWM files ANYWAY after of course I change my Google account credentials But you'll have to wait a month for them as I'm far off from a connection that can upload ~ 900MB reliably. Plan to stick around this sub forum regardless of whether I buy the same phone or not as one of my friends has one and I'm the go-to techie around here :/
For all you out there, these CWM files are based around the MB not ME version of the files so it SHOULD* work on AT&T phones without all the AT&T crapware and should require NO hacks / tweaks to work the hotspot and other features

The service center do not have FXZ stored in there system, AFAIK they connect the phone to an application, this APP contacts the motorola server and recognize the build of this phone and then downloads the relative FXZ and flashes it! This is all done by the APP
I am really not sure if we can use the Atrix 4g recovery, but its unlikely we can do that.
Now i do have a copy of stock 2.3.6, but we cannot use the hotspot App and other system apps directly as they are not deodexed. Correct me if I am wrong please
Well , those guys simply said NO !! And they asked ME TO get MOTO to send them the FXZs .. as if .. :/
Do you mean to say that the app downloads a 500 MB compressed file EVERYTIME one flashes a phone ?? Very unproductive. :/
I just hope MOTO knows what they're doing dishing out service contracts to people who apparently don't know how things are meant to be.
Anyway ,I've recieved the refund email from flipkart and this phone's going back. Lets hope I pick up a better phone in a month , else its back to another A 2. Great phone, sub-standard service is all that's pulling it down.
And with the imminent launch of an S4 proccy in the rumored Atrix2 w/ a 720p screen, I think the future holds a lot more to offer than the A2's OMAP -- heck , I have problems decoding HP h264 vids --- B frames anyone ? I believe even the lowly adreno 220 and the Mali-400 can handle them with ease.
Furthermore, correct me if I'm wrong ,the A's processor claims to be dual channel capable, but with one channel available to each core, is that really what we're looking at ?

You should complain about that service center. I flashed files as stated above and it worked.
I have been waiting someone to upload backup of Indian firmware but I am kind of fed up waiting for it to happen, so just now I went to service center and the guys there told me that they don't have stock firmware for it BUT then he spoke to someone in Chennai and I am told that they are going to receive stock firmware in an hour or two and he will flash it and let me know by 4pm today, so basically they do have stock FXZ, not every center may have it ready but its with them.
So I have left my phone there till evening, he said he will flash the stock firmware and if it doesn't work they will process a replacement for me and I will get a new phone. Simple as that. Motorola service centers are managed by Redington, if they are refusing to honour your service request you should complain to Moto as well as Redington. We need to let them know that they cant take us for granted after selling a phone.
And since you are going to get a refund anyway, why not try and flash the files I recommend? You have already bricked your phone, so even if it doesn't work you are still going to get a new phone. N I am sure when it works you will change your mind This is a fantastic phone as per my opinion. I would anyday stick with it.
---------- Post added at 12:43 PM ---------- Previous post was at 12:19 PM ----------
And all people who may need Indian Stock firmware stay tuned here, as soon as I get my phone back I am going to take a CWM Backup and upload it here, since I have 3G my upload speeds are not that good, so it will take at-least 2 days after I receive my phone, so that I can upload it here but I am definitely going to do it. AT&T users will benefit a lot from this. Just waiting desperately to get my phone back.
Sorry folks, Moto service is really bad. The guys at service center initially told me they will receive FXZ to flash, but seems like they didn't, they are processing my request for a replacement shame Moto, your service centers doesn't even have firmware to flash.. I am gonna complain to Moto as well as Radington. Its such a simple task for which they are giving me a replacement, if I have FXZ I can do it myself.
finally ordered a razr for 26.4k, a steal if u ask me. lets hope it pans out better than the A2..
Hello,
Totally new to this Forum, and to the idea of rooting/unlocking phones at home. Hopefully someone can help or provide guidance. I'm sorry, I'm sure this answer comes up somewhere on here, but I have not searched.
Here is my predicament.
I got a new phone, and was going to try to root/unlock my old phone (Samsung Galaxy S Vibrant i9000M) for my GF's daughter.
So...I downloaded Odin 1.3 and ran the instructions as I found them on another site. They supplied the link to a *.tar file that would root the phone. After I ran that, the phone would power on...but not pass the Splash screen. When it boots the i9000M turns to i9000 and the lights on the front of the phone flash..and it stays on that screen.
I downloaded a different version of Odin (1.85), a new tar (CF-Root-XX_XEU_JPY-v1.3-BusyBox-1.17.1) and pit (s1_odin_20100512) files. I've run all of those...and now the phone will not power at all. If I run into Download mode...it works.
Thoughts?
Is this phone able to be saved...or should I just take it with me to hockey tonight and practice shooting with it.
I got it all to work...after much reading and searching, I found the original Stock ROMS to bring me back to factory, then properly flashed and unlocked, got the SIM to work and even figured out how to set up the APN for internet access via the phone service....initially I only had it working on wifi.
A new question. Is an unlocked i900M (Bell) the same as any other i9000? I want to upgrade her past Froyo 2.2, because her app/game selection is rather limited. Everything I am finding references i9000...and doesn't say with it is a Gingerbread upgrade for a stock phone, or unlocked phone.
I apologize if these are noob questions, but I've never done this before.
Any help.guidance would be appreciated.
Matt
