[Q] [i9020a] question about roms - Nexus S Q&A, Help & Troubleshooting

This might be a stupid question but here it goes..
For the i9020a nexus S model are all GSM roms compatible with it? What I mean is most of the roms that I see are built for the GT-I9020T. Is there anything I need to be cautious when flashing a rom? Or is the custom kernels or radios the ones I need to worry about? Also what Rom and kernel do you guys recommend for the i9020a version.
Thanks

As far as I know the technology in the i9020T and i9020A is absolutely identical - almost. The only difference is the 3G band on which the radio chip in the phones operates. For the i9020T it's 900/1700/2100, for the i9020A it's 850/1900/2100. The firmware is identical in the two phones (and in the i9023 LCD screen model sold overseas, for that matter.) The Nexus S that's different is the 4G model on Sprint - for that one you need a different ROM.
Before you go experimenting with ROMs be sure you have the Android SDK installed and drivers sorted out for your phone. From what I read here 90% of problems with flashing ROMs, recoveries and kernels amount to Windows driver issues. For me using Linux it was a no brainer to unlock, replace recovery and root my phone (an i9020T) and get my first ROM installed - CyanogenMod. The instructions in the i9020A/i9023 thread here on xda-developers are pretty clear http://forum.xda-developers.com/showthread.php?t=1007782.
As it happens CyanogenMod didn't prove very stable for me, and the ROM I've settled on for now is Jonathon Grigg's Infin1ty http://forum.xda-developers.com/showthread.php?t=1029118. Your mileage will probably vary. Look at the ROM summary thread http://forum.xda-developers.com/showthread.php?t=1067813 and don't be afraid to experiment. I tried several other ROMs before I settled on Infin1ty.

I've been trying out most of the Nexus S roms with my I9020a for the past couple of weeks and I haven't run into any issues yet. From my experience, so far, any GSM Nexus S rom will work with the I9020a.
Generally, unless you really mess up flashing a radio or accidentally flash a Nexus S 4G ROM, it is almost impossible to brick a Nexus S (similar to the Nexus One, my previous phone). As long as you have one solid stable backup, you should feel free to play around with the various ROMs available. Worst case you can always restore your backup.
Enjoy!

Thanks for the advise guys one last thing is there a particular recovery clockwork I should be using for the i9020a?

Just follow the advice in the post I linked to above. Follow their instructions exactly the first time. Once you get familiar with things you can try recoveries other than the one they recommend. Keep it simple the first time though.

[Q] Matter Of Choice

Fast and brief.
I want to buy a new, unlocked, HTC Inspire 4G.
I'm a noob, and don't know anything about rooting, Android, or whathaveyou, but am keen to learn and am not an idiot.
Should i buy a phone that's already rooted running on Inspired Ace or just buy a stock phone and root it myself and flash a custom ROM of my choosing?
In other words, can i, being a noob, handle rooting an Inspire and flasing a ROM all by my lonesome? What's the LATEST and BEST guide on rooting and everything else you need to get it working? I've seen a lot of literature with (outdated) near it and it's kind of annoying.
Another even stupider question. Since the phone is already rooted, i can, if i want to, flash another custom ROM if i don't like Inspired Ace without seriously f-ing it up, right?
welcome to my world as of last week. This week, I've learned that rooting is easy on the Inspire 4G. You just have to get the hack kit: http://forum.xda-developers.com/showthread.php?t=952352 And I'm gonna quote attn1: READ THE EFFEN MANUAL. I cannot stress that enough.
Once you've done all of this, you'll have a rooted Inspire 4G, but it will be on the Desire HD radio/ROM, and you'll need to flash an Inspire 4G radio, so you can have a solid base.
Go by http://forum.xda-developers.com/showthread.php?t=1058042 to get a rooted Inspire 4G radio/Rom base with the latest HTC update. Then make sure you download ROM Manager, and from there you can backup your rom, and try out custom ROMs.
If you wanna watch how I did it, go to http://forum.xda-developers.com/showthread.php?p=14618851#post14618851.

1 IMHO, I'd get a new one so you have a clean, fresh slate to work with. You don't ever truly know how the previous owner used the device(excessive OC level on a regular basis...)
2 Yes, it's very simple. I feel it's best to get your contacts imported from the sim then sync w/Google but nothing more. This way you don't have to reconfigure your phone after rooting.
3 The Ace Hack Kit from att1 is the easiest and best way. Any other method is based on his work. All the info you need is in the first post. If you have an issue, search the thread. If a concise answer cannot be found, search the forum. If still no answer, post your question in that thread, then be patient and wait for a reply. If no one can answer, at the very bottom of the first post, att1 has a link to an IRC chat channel for helping w/ issues, try there.
4 Yes. The number one rule for flashing is ALWAYS make a nandroid(basically an exact image before any changes have been made) before doing anything. This is your safety net and gives you something to fall back on should there be an issue post flash.

okay, so buy a new one. Check. Root using kit and read manual. Check. After i root, which comes first? A new radio or a new rom, or what order do you use? Can you recommend as advanced users, the most stable custom rom and radio for the inspire? This is where i usually get confused. What to do after rooting, in what order.

After you root, your phone will say "HTC Desire HD" in phone information. before you install a custom ROM, install this: http://droid.neolobster.com/roms/Ace_Cingular_US_SL_1.84.502.11_Radio_26_06_06_30_M_PD98IMG.zip (from thread http://forum.xda-developers.com/showthread.php?t=1058042) . This is both a ROM and a radio, and it will give you the most up to date stock rom for the Inspire 4G (not Desire HD), but still rooted with sideloading allowed. From there, download two apps: titanium backup (to backup apps), and most importantly, ROM Manager. ROM manager has links to download many different ROMS, but before it prompts installing them, it also gives you the option of backing up your current ROM and wiping data cache, and then loading the new ROM. The link I gave u will be your base ROM.
The most popular custom ROM tends to be CyanogenMod7. I've tried that, CoreDroid 6.6, and most recently, TB Fusion 1.1.8.3. If you like HTC Sense, go with the latter two, or other Sense ROMs. If you don't like Sense or don't care about Sense, go with something like CM7.
Always remember something here: Desire HD and Inspire 4G are largely the same phone, save a few things. Most custom ROMS are optimized for the HD, but hopefully that will change soon.
Okay. Thanks. So root, install base radio and ROM, then install backup and ROM manager and then install custom ROM.
I see that the custom ROM is Cingular_US. I live in Romania and will be using the phone in Orange Romania. That's not a problem, right?

No it wont be a problem. One note though. I don't know if you already knew this when you bought/buy the phone but the inspire uses north American bands for 3g(850/1900) you will not be able to use your 3g service as it runs on 2100. If 3g service is important and haven't bought the phone I would suggest you get the desire HD as it runs (900/2100) for 3g

How do i find out what frequencies Orange Romania works on?
Orange Romania runs 3g on (900/2100)

[Q] Windmobile Version of SGS4G

Is the Windmobile of the S-4G available to be flashed to ICS? I've flashed a few phones, just having a hard time figuring out what variant the Windmobile version is and if it's upgradable with cyanogen to a later version, debating about upgrading tomorrow to one.

Try looking at this thread: http://forum.xda-developers.com/showthread.php?t=1552119
Bhundven was able to confirm that the phones are [almost] identical with a few small differences and that flashing ROMs for the 959V should be safe. Again, read the thread for more detailed information.
Pay close attention to this warning though: "If the rom contains bootloaders, please DO NOT flash them until we can confirm there are no bootloader differences."
As FBis251 said later, "TLDR: Don't flash bootloaders if the ROM contains bootloaders. No CWM roms contain bootloaders, a lot of heimdall/odin roms contain bootloaders."

If the phone come with gingerbread installed yes. You just have to be very careful. The bootloaders we have are for the T-mobile version. So if you foul up and need to flash back to stock with bootloaders you are boned. However if you just want to flash a flavor of ics this can be done with the purple link in my signature. That will get you rooted with clockworkmod recovery then just flash one of the flavors of ics.
With all that said search is your friend, this information is posted in this subforum AND the general android forums. Our dev bhundven has a couple threads on how to do this.

I've asked people if they have the stock leaked rom for t959w to PM me, and no one has.
Someone also offered to try flashing t959v bootloaders, but never got back to me. My guess is that either it worked great and he is quietly rockin some rom in the dev forum, or it bricked his device and he didn't know what to do with it.
If someone has a t959w they are replacing, I'd like to try my hand at applying AdamOutler's unbrickable mod and experimenting with bootloaders on that device.
There is also the t959p, which is the telus galaxy s 4g.
This phone is different then the t959v or t959w. It has cg2900 gps, where as we have a-gps and there are a few other differences.
The same goes there. If someone has a t959p, I'd like to try the same.
Thanks everyone. I normally search, I was just in a rush as I was getting a new phone this morn and it was between the S 4G or the Q with the slide out keyboard, but it seems no one decided to do anything on the Q, so I went for the S 4G. I'll do lots of reading before I decide to flash or not, I just like having the option.

Is there a 4.0 Stock International ROM or Firmware

My boss gave me his galaxy s2 skyrocket to flash
i was originally running JB 4.1 on a custom rom, but i tried like 2 roms and they were to buggy for him and not stable
so since i couldnt find a really stable JB 4.1
hes asked to see if i can find the 4.0 Firmware of this phone but for the INTERNATIONAL version
I wasn't even aware the Skyrocket had a international version
What do you guys think
?
Samsung Galaxy S2 LTE comes in:
ATT: SGH-i727
T-Mobile: SGH-T898
Rogers: SGH-i727R
International: GT-I9210/T
ATT & Rogers are easily interchangable, the Hercules (SGH-T898) may need a little tweaking to get it working right but not too sure on the international version, I've heard people flashing the international version with CM9 for the SR but haven't heard of anyone flashing the International version of ICS to the SR.
The hardware is identical with only difference being the CPU Model# which is the same CPU they used on the T-Mobile version (APQ8060) vs (MSM8260).
Really its best to flash only the ROMs that are made for your phone but if the hardware is similar you can probably do it but I don't see why you want to.
If he wants he can use AT&T stock, CM9 or a custom ROM.
Does he want something from the international version of ICS?
Remember using a different ROM for a different phone you will need to have a different Modem and may have a chance to brick so only do at your own risk.

He wants international so he can get be able to Text in Chinese etc etc
When I upgraded him to 4.1 the Chinese stuff was all good to goo
Had issues getting it to work on 4.0, the text would come out in Chinese, but the receiver would get a bunch of symbols, like i said upgrading to 4.1 fixed this, i think 4.1 and more languages or something
Thats why he wants international, he travels a lot as well so its convenient.

I've flashed several phones with several roms, I have my own Galaxy S3 running perfect on a AOKP rom
When i flashed my bosses phone I did the usual, wipe data/ dalvik / factory reset / flash rom
First ROM i used was Superlite, phone would go black and would require force shut off, this would happen randomly during idle or something or overnight
So i switched to SKYJB 5.0
no more screen hanging up black but got screen flickering issues, so i went into dev options and checked the H/W option..
as of now he took the phone back since he said that was the real issue.
Which rom would you recommend that runs very stable?
things have changed, like i said all new cm10 are stable, well mine is which is superlite v7.0, but that one has no chinese support, but superheavy does, cm10 is 4.1
as for international, he just has to worry about the radio and apns
So which CM10 would you suggest? specifically

not a good question to ask on this forum, "which is best", read the individual rom threads and see which ones would suit your/his needs, but since i only use my rom, then superheavy should fulfill his needs, its posted on my sig for superlite

I'm about to flash your Superheavy rom. I believe i might be on a custom kernel, could you point me a stock kernel or kernal that runs great on your rom? Thanks

Root the Verizon S3 1535

Hey all,
After looking over some of the ROM's available and other information regarding the S3, I'm a little confused on the rooting process. I've rooted my motorola droids and xoom, but this one seems different, no doubt due to 4.1.2, which my S3 is running. I understand that there are 2 sets of ROMs in here, with one set being specifically for Verizon S3 Android Development. Does it matter which I use? I'm liking hyperspeed rom, from what I see it looks good, but most of the root guides/walkthroughs I've seen are from last year. So my question is, what do I need for my unrooted Verizon S3 running stock 4.1.2 to root and install Hyperspeed or other JB Roms. One guide was very detailed but links to Odin and other files didn't work or was an old ICS guide. Need some pointers, been a while since I've done this.
Thanks in advance...
I recall using an app called "EZ Unlock" to root the phone, it was super easy. Once rooted and unlocked I think the next step was installing ClockworkMod or similar recovery. Then do a full nandroid backup. You should probably read the thread on backing up your IMEI as well, I don't know if its still an issue but you should do it just in case.
Now you can start thinking about the two sets of available ROMS.. Basically you have numerous flavors of TouchWiz and AOSP roms. The TouchWiz roms behave more like the stock os on the device and still have the Samsung camera, etc while the AOSP roms are more "Nexus" like. Personally I prefer the AOSP side of things and have settled on CM10.1.

EZ Unlock is for unlocking the boot loader not for rooting your phone. The IMEI issue normally happens when flashing AOSP ROMs but it has happened when flashing TouchWiz ROMs.

"New" note 5 owner custom rom flashing questions

Hey There,
Got my self a certified Pre owned note 5 from T-mobile which has been pretty fun to play with. Now I've gotten the Rom flashing bug, however my note came completely updated to the latest "N920TUVU4EQG3" firmware. Can I still just flash the latest TWRP through ODIN and then wipe and flash whatever Rom I want from the Tmobile note 5 section? Or will this cause issues?
Am I correct in seeing that there are no custom roms or custom kernels based on the latest tmobile release "N920TUVU4EQG3" firmware? I guess what I'd really like is just to run stock custom firmware with an awesome kernel and I think id be just fine.
Also do the Kernels/Roms over in the international forums cause issues for the T-Mobile variant?
Also any suggestions for someone who hasnt touched a samsung device in a few years from a flashing/odin perspective are welcomed :]
Hi, I have the same situation, somebody who know something about, so many thanks.
