If you don't know, you don't need to know :)

but anyway, ME7 breaks the ability to flash custom ROMs
[Verizon Samsung Galaxy S 4] broderp:
Gee thankls! :o Now I know!
[Verizon Samsung Galaxy S 4] Dolphlungegrin:
ME7 is the new bootloader installed on Verizon's update a month or so ago. The previous version was MDK which could be flashed back to the pre-release MD2 for root access. The MDK and MD2 also allowed you to install a custom recovery partition like TWRP or CWM which allowed you to do full nandroid backups and reflash the phone with a new ROM. ME7 is locked and so far you cannot install TWRP or CWM effectively preventing anyone with it from flashing new ROMS. ME7 also cannot be flashed back using ODIN into the MDK or MD2 verisons. So right now, everyone with ME7 (me included) can only gain root access at the most.:(

I have an I337 running on tmobile network. I have tried both tmobile's and at&ts roms and both get 4g but the att&t rom seem to connect faster. I am currently on mdl modem and woul like to experiment with tmobile's modems and am wondering if it is safe?

Thanks in advance:)

I heard doing this could possibly erase your IMEI number. Personally, I'd only flash my carrier's modems. Just to be on the safe side. :D
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] AxAtAx:
Its not wise to use other carriers modems, and it will clear the IMEI, but I have heard that it can be done. Kinda of a hit and miss thing, if you are going to pursue it, backup your efs first.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] Airtioteclint:
Thank you both for replying, it sounds too risky for me I'm glad I asked first.

good choice. in all the diff radios i have flashed on various phones they gave no more than minimal improvement if any

i thought initially the mf3 radio was better, now not sure
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] Airtioteclint:
I hope I'll never have to go through that but if I did, can you share the steps? With my s3 (may it rest in peace) a simple "reboot nvbackup" and "reboot nvrestore"command in terminal emulator was all it took, and it saved me many times. Would this also work with the s4?

You're right that has been my experiences with different radios also.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] movielover76:
replacing the IMEI, talk about a hardline approach from Samsung.

I remember on my S1 flashing radios from S1's all over the world, Europe, China etc etc

Though thanks for this thread, I was actually wondering about flashing a canadian modem, to unlock AWS and since it's one build higher than the AT&T modem
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] AxAtAx:
Just a reminder, it is not wise to run other carriers modems, the modems we have are sufficient to do what you need, and if you find a way, you will not see much of a change if any.

Good luck to all.

Hey man, i am starting to think i would have to flash another variants modem on my s4 m919v because i dont see any modem files for my phone on xda or atleast i cant find many because this variant isnt all that common. What do you think its possible right?

Oh and the reason i want to flash modem is because i want to flash an older modem for s4s that allowed them to be unlocked using the *#0011# code and i cant do that currently. I have heard flashing an older one will allow me to unlock my phone.

I have been trying to resurrect my bricked HTC Pico. I followed this thread http://xdaforums.com/showthread.php?t=2048312 and found the rom to be very good and fast but one issue so if someone can let the developer know, After following all the instructions and installing the rom I can't do anything else due to it saying there is no more space even though I have set up the extra partition as ext3 before installing the rom.

Sorry, don't know who you are talking about and I tried the RUU but get a certificate failure. As I said, I tried everything suggested, even a full factory reset.

Oh and I have already done the suggested with extracting the files from the RUU
[HTC Pico (Explorer)] phatmanxxl:
OK I talked to another guy on a tech site last night who is new to the pico and flashing ROMs.

Its been years since I delt with an HTC device. Google around using 'certificate failure' in the keywords. Hopefully somebody had a similar problem and figured it out.

Sorry I can't be of more help.
[HTC Pico (Explorer)] scotslad2k:
Thanks, it seems that because the phone was originally a T-Mobile phone, there are no RUU's that will go onto the phone because it won't accept a generic RUU. It would need to be a T-Mob RUU for the Pico, I have scoured the net but nothing so i'll just keep trying to sort the memory issue somehow.

So my work IMAP email just out of the blue stopped auto syncing and showing notifications, obviously its not showing notifications because it is not syncing. Anybody else experiencing this? I found a few threads not on XDA that have said it may have happened from the last update and the only fix was to delete and setup again, but even that only fixed it temporarily and the guy said he had to do it like 5 times, in my book that is not a fix......Any ideas??

[Nexus 4 Q&A, Help & Troubleshooting] pepsy11:
Hi

I recently got a Nexus 4 after always having had iPhone, so I am quite new to this. =)

Is it possible to root a Nexus 4 without losing the data folder? Either by simply never deleting it or is there any way to get a backup of everything in the data folder(including hidden files and everything in /data/app, etc.) to my computer(windows or mac), when it isin't rooted?

All the rooting guides I have looked at until now says that they will wipe the phone, but I also read a discussion that said it were possible to gain complete access to the data folder by either manually rooting the phone or by not unlocking the bootloader? I posted somewhere else and someone there said that what I want is SU in the OS, but I am not sure about that, since I haven't heard more.

Thank you =)
[Nexus 4 Q&A, Help & Troubleshooting] abaaaabbbb63:
You can root without wiping data. The trick is to not boot into Android after unlocking bootloader. You do things like this:

1. Setup your pc ( drivers, fastboot )

2. Unlock your bootloader

From now on, you must not boot normally, or else your phone will be wiped.

3. Flash a custom recovery.

4. Enter recovery

5. Wipe cache

6. Flash the SuperSu zip to root.

7. Reboot.

Now you should be rooted, and your data should not be wiped. But I'd make a backup is I were you.

[Galaxy S II Q&A, Help & Troubleshooting] theultimate1:
4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.

What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).

It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.

Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!

I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?

Or should I be doing something else?

Any help would be greatly appreciated.

P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this :)

5) Read about jb settings/issues.

Sent from the little guy
[Galaxy S II Q&A, Help & Troubleshooting] jsiv:
Hi OP,

I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.

Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.

After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.

My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.

What REALLY helped was getting a replacement battery.

I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.

Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.

Just my 2 cents.

S2 battery life

yea.. u said it...even i have tried several custom roms ( NeatRom, WanamLite,RR etc) all give 15-19 Hrs max.. and this also by tweaking all the settings..

S2 is a undoubted beast, but the cost in terms of battery is very hight..my previous Android Motorola Defy was a Mammoth in itself..huge custom fanbase and loads of ROMS + Awsome battery.

Any ways i got no regretts for having a S2..but battery s a lil concern..

Currently am on Asnet MIUI V5 and its going good..fast, responsive, smooth and decent battery of 18 hours avg.. :)

Do you calibrate battery after every ROM change?
[Galaxy S II Q&A, Help & Troubleshooting] theultimate1:
Can you please point me in the "settings" direction? I think I'm doing all things right, going real low on app usage, sync-ing of apps, screen settings, etc.

What exactly is battery calibration here? Please pardon my ignorance. I did a full charge when my phone hit got switched off the day after upgrading the OS. Is there something else I must be doing here?

I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.

How good is the Cynaogen Mod ROM in terms of battery life?

Or would it be wiser to switch to Android 4.0/ ICS?

This has to be done every time you do a ROM upgrade or change ROMs.

CM has excellent battery life when compared to other ROMs.

If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.
[Galaxy S II Q&A, Help & Troubleshooting] bernie279:
As reported before, it seems that many official JB ROMS are not as optimized as other national versions and are battery hungry. It was suggested to upgrade to the French release (XEF).
[Galaxy S II Q&A, Help & Troubleshooting] theultimate1:
I did this... and unfortunately, it did nothing in my case.

I went to the CM site, but I didn't find any stable build for SGS2. Is there a thread on this site I can refer to for the same?

Also, what's the best way to go about installing a different ROM? I have so many apps, sms messages, pics, mp3 files, 3gp files, etc. Sure I can take a back-up onto my SD card. But won't I lose all the apps once I flash the current Android installation and install a new ROM? Any article or video on YouTube that addresses these points? Please point me in the right direction. I practically don't use my phone even half as much as before and I'm having to charge it twice a day, as against once a day earlier.

Also, the rapid battery loss seems to be causing the phone to heat up a lot if I'm on a call longer than 15 minutes or having the screen on for 2-3 minutes straight.
[Galaxy S II Q&A, Help & Troubleshooting] vish91:
There is no stable version of CM 10 on I9100 because of the some issues. You can flash one of the nightly builds.They might not be necessarily unstable.

No you wont be losing everything when you install a new ROM.You lose once you do a data wipe.It is suggested you wipe everything before you install a new ROM.

With a data wipe you'll lose the following - SMS,contacts,call logs,apps installed and respective data.

What you wont lose - Anything stored in the sdcard partition - Pictures, Videos, Music, Apk files and Anything stored on the Ext SD card.(unless you format them specifically)

Best solution is to use titanium backup app(You need root). This way you can backup your apps and resp. data,wipe data-install ROM,and restore the previous backup on the new ROM.

[Windows Phone 8 Development and Hacking] compu829:
So after reading about all the App Store hacks that have developed around Fiddler2, I decided to give it a go myself. After setting up the proxy, I noticed that most SSL-based transactions were failing to connect on my device (Windows Updates, Email, etc).

I exported the SSL cert that fiddler 2 installed on my development PC, emailed it to myself, and installed it on my Windows Phone device. LO and Behold, Most of my SSL issues went away! (App store still woudn't auth). More Interestingly, Windows Updates started checking for updates successfully. These transactions are done with SOAP calls.

The basic process is as follows:

1. Phone initiates a connection to the windows update server

2. a series of cab files are downloaded containing certificate and base URL info of the update server

3. the phone connects to the update server with a list of all updates it has installed as well as a unique device identifier.

4. the server responds with a list of updates that it wants the phone to evaluate.

5. If the phone decides it needs the update, it sends a request to the server for instructions to deter

6. the server responds with a specially crafted packet that contains a link to where the microsoft cab can be downloaded from as well as a checksum of the cab file and evaluation instructions to determine if the update is needed. (checking registry keys, etc the SOAP commands contain things like RegRead32)

7. the phone then downloads and installs the update, if needed.

Fiddling around with fiddler, I was able to remove the "filter" GUID from the phones request to the server. As a result, it evaluated and installed any update it could get its hands on. The Hardware Test app still shows that my last update was 5/1/2013, but the number of updated packages included in that update jumped from 83 to 200!

I have some more experiments I would like to try (such as trying to blindly write a reg key instead of just reading it...anyone know of a good one?). I am also wondering if I can somehow package a Microsoft cab file, and tell the update mechanism to download and install it. Depending on how it evaluates the cabs, I might be able to get away with signing the cab with the private key from the Fiddler certificate I installed.

Just thought I'd pass along :)
[Windows Phone 8 Development and Hacking] GoodDayToDie:
Very, very nice finds! I had noticed the cert pinning used on the store and on dev-unlocking, but apparently had failed to look into the update process.

Give me a little while and I'll find you the reg key used for dev-unlock. I can't guarantee you that I'll be able to give you the exact value you need - they seem to have changed the format since WP7, and I'll be working blind from templates and policy files here - but it's worth a shot. Mind you, I wouldn't be surprised if the whole process is read-only, or if the responses from Microsoft are signed (although you could try re-signing them, I guess). For what it's worth, creating an entire update from scratch (or even editing one) is unlikely to work; Windows has required a Microsoft signature (not just any trusted signature) on update files for many years now. It's certainly possible that they messed that up, though.

I also kind of want to see if some of the recent ZIP signature validation bypass exploits from Android (where you could create a ZIP file containing multiple files that have the same name, and the original would be used for the signature but the *last* copy of each file would be the one actually unpacked) might be made to work as well. I've got some ideas about that... not sure if it would work for the update format, though.

Please keep researching this!
