[Q] Rooting a U8800 that's currently on 2.2...

Good evening all,
Basically I'm looking to root my girlfriends fathers U8800, it's currently running android 2.2. He's complained that its got major battery drain so I figure I can find a ROM here that can help that.
I've read there are 3 different types of models for this handset. How do I know which one we've got? If that's relevant?
I've found this thread that seems dead easy to follow, http://forum.xda-developers.com/showthread.php?t=1420728 , am I ok to proceed?
When I've rooted it, do I just flash a rom via CWM like I would with my galaxy s? And will I be caught out with bootloader issues or little things like that?
Thanks in advance.

If the device is the U8800 regular model(not pro or plus) you can follow the guides of the link.
And yes, you can flash a rom from cwm recovery.
Only one suggestion. If you flash the latest stock gingerbread rom(I think is the 522), search for a thread called "get your pink screen back" on developing section. The after 518 versions have the bootloader locked, and on the above thread you will find how to flash the unlocked bootloader from 518 stock rom.

Thanks for that, I'll get on it tomorrow with an operational head. I'll do the pre root checks and make sure I have everything I need in place before I get going.

If the device is not yours I suggest you to do nothing. There's no better Rom, in terms of bug free than the original one.
Custom roms always have this or that and will require attention, which I'm sure your fatherin law can live better without these issues and concerns.
This devices have an high consumption and he has to get used to it.
Now if the device was yours meaning you would be using it daily, than i would advise you to install aurora. I don't like it but have to admit that is very good and stable.

Did you look to see what is causing the battery drain? I have a friend with a stock GT540 that had serious battery drain. Turns out it was the GoSMS program. Deleted the app and now his phone lasts 5 days between charges. Switching a rom won't help if the problem is an app.
1) Get cpu spy and see if it is going to deep sleep
2) If not sleeping, turn off running applications one by one and test via cpu spy to find out which one is causing it not to sleep.
3) Either remove the offending app or use Autorun Manager to modify the receivers (if rooted)
You can fix his problem without changing his rom. If he wants root, superoneclick can root 2.2, I just used it the other day. Also make sure he is on the latest 2.2: b138sp04 or b163. I prefer b163, even though it is the China rom, because I like the Huawei launcher better that stock.

That's not true... official 2.2 is the slowest thing in existence. If he just needs stability then Ezets CM7 is the answer. There are no bugs with it (except wifi tethering) and it's much much faster than stock...
Also he can undervoltage it to preserve battery life more than stock ROM.

You want the best 2.2 you try Void Eridanus. Everything works.
Want the speed, OEX rom it's a Ferrari. Everything works less the mms with data off.
You can also keep the stock Rom, root it and just apply a ffranco kernel. This way you gain the speed.
3 good solutions here.
I'm don't revert to stock Rom for 2 reasons, cam quality and battery life, otherwise i would use stock Rom without a shadow of a doubt.
In terms of stability and all working it's stock 2.2 Rom and this is unquestionable!!!
I have been trying ALL roms and ALL respective versions since July 2011 therefore I do speak by personal extended experience
I repeat once again, in the conditions you mention leave the phone as it is. If you want to do something just root it and that's it.

as a matter of facts i had my phone with so many rooms that i can even say how many but if u want stability i recomend oxygen... if u want stability and good looks use miui 32...
last .32 miui that i used was from miui portugal in english and nothing to say about that...
battery for 2 days and all smoth...
but my phone is weird... he can take almost every rom and be usable...

The issue with miui pt versions it's the cam quality that is horrible. It's just this detail that it's not very good. The rest it's perfect.

Hey everyone, back for an update and some other steps. basically, he got frustrated with how the battery so he went out today and bought the newer huawei. Reading eveyones comments here i think its due to the ammount of apps and being on froyo hasn't helped any thing, but anyways its now my new toy to play with. So far, followed the link i posted in the first thread, rooted and installed the latest CWM (v5). I'm now a little confused when it comes to the get the pink screen back, should i follow this thread http://forum.xda-developers.com/showthread.php?t=1457490 now before flashing a new rom or afterwards?
Again thanks for all the help, I'm almost done bothering you all for now
Edit: Reading on some ROM's and the comments above, i should install B518 stock ROM then flash the bootloader fix from the thread posted above then i can install other ROM's? If so where can i get the stock B518 ROM and how do i know which version I'm using? Sorry and thanks again.

First, which rom you have now?
You can find the version from settings -> about phone.
If you have a newer than 518 version you need to change the bootloader with the one from 518. If you have 518 you don't.
Also check which version of kernel you have(is on about phone also)
If you have a 2.6.32 version(which mean that you have froyo rom), you can flash only roms with this kernel version. If you have a 2.6.35 version, you can flash roms with 2.6.35 kernel or 3.0.8(as aurora ICS).

Basically its a stock froyo rom, im looking to get to gingerbread by the end of tonight but currently im stuck on the huawei splash screen after i did a data reset in CWM. Can still get to CWM though.

What rom you want to flash now?
A custom gingerbread based of froyo's kernel 2.6.32 like CM7.2, oxygen or miui, or the official gingerbread?

Im not particularly bothered, something that won't brick the phone and is stable. I'm more worried as to why it wont boot now after a data reset.. any suggestions for that?

You can use adb and logcat function to see where the problem is. Usually when some errors prevent device to complete the boot proccess, this piece of code loops. You need to have some knowledge of programming though, but maybe is something easy.

and now i have blue screen.. what can i do? or have i bricked it?

Where you have blue screen and what you did?
Usually blue screen instead of recovery mode, means that the recovery.img is deleted from .cust_backup/Image folder

basically, i formatted something, reboot and soon as the huawei logo appear a blue scrren rolls down. when i plug the phone into the pc it detects a folder but its empty, the phone is detected as qualcomm now..

Yes, seems that you formated the partition which has the Image folder with all system images. So, now you need to flash an official rom. You can either flash a froyo or a gingerbread rom. You can avoid this only if you previous had take a backup of this folder. In this case just put all files in (empty now) image folder.

Request Rom Manager vs Boot Loader Clarification

Not a Dev, but not a Noob, either. Formerly had a SGH-i897 Galaxy S for 3 years and flashed like crazy on it, while transitioning from Eclair to Froyo to Gingerbread to ICS to Jellybean, mostly using the fine offerings from the AOCP Collective folks. While familiar with Odin, CWM was my usual go-to utility.
Upgraded recently to a SGH-i337 Galaxy S4. Must have owned it for two, maybe three hours, before I rooted it with MotoChopper. This allowed me to re-install Titanium Backup. I left it as merely rooted, while I read up on CWM and some new-fangled thing called TWRP, which I wanted to get installed before casting about for a new ROM. (At the time, AOCP did not have an offering here, or it would have been a no-brainer for me.)
One morning, I turned on the phone and noticed it was doing an OTA update. . . . . . . . .
Mildly curious, I logged onto XDA to read what the community thought about the update, only to discover that I had missed all the dire warnings by a day and my (now) version I337UCUAMF3 ROM had it's boot-loaders locked from a blown Q-Fuse, courtesy of Samsung and AT&T.
Took me a week before I found the rooting solution from jortex, but thankfully, I'm now rooted again.
This background now leads to my questions:
I have ROM Manager Premium (from previous purchase) but have not installed it.
I was aware on my previous SGH-i897 that mixing the Gingerbread and Jellybean boot loaders was like, a Bad Thing when flashing ROMs and would promptly brick the phone.
Does CWM require the ability to load from a boot loader?
I know it creates an update.zip file to restore the original ROM, and usually does so by using whatever ROM is installed at the time.
So wouldn't it just create an update based on the I337UCUAMF3 ROM?
Even if I can't flash new ROMs (unless or until somebody comes up with a Q-Fuse Fix) couldn't I at least have all the recovery and .zip flashing of apps and cache clearing menu choices available to me from CWM?
Or would the act of just installing CWM on a I337UCUAMF3 ROM immediately brick my phone?
In Other Words, how close can I dance to the water's edge?
Been to the ROM Manager web site and they claim I can do any thing at any time.
(Easy for them to say: It ain't THEIR phones!)
Been searching these threads and can't come up with anything explicitly stating yea or nay.
So far, I have been happy enough with the TW stock ROM, but I always felt better being able to boot to recovery to fix things, on those few occasions I got just a leeeeeetle too close to the Bleeding Edge!
What is the consensus out there?
Will CWM 6.0.3.6 bork a I337UCUAMF3? Yes or no?
Would appreciate any thoughts that might enlighten me! :fingers-crossed:

It sure could brick the phone, the only thing you can do at the moment is root. I have seen a couple people try running a recovery on it, and it required a jtag service to restore the device.
Be careful.

This phone is far different from the Captivate. There is no flashing anything on MF3. Basically you are waiting for a work around if that is even possible.

This is the update schedule for American carriers. Does that mean that unlocked phones will get it sooner? I hope so. I only just bought the note 2 (Best decision ever) and would love it to be running on 4.3 ASAP.

I live in Brizzy too and I'll second or third that if its the only way we can get it? Sorry for the possibly stupid question, but is it true that if you have rooted and installed a custom rom, then you won't get the push update from your carrier anyway?... so.... the only way to get 4.3 on my (and I assume your rooted phone) is via custom rom download?

or if you go back to stock.
have issues with the ota updater as soon as i root my device. The moment i do that i get the message that my device has been changed and i cannot use the updater then. if i flash stock withouth root i don't have this issue.
reckon its best to make a backup of your apps with TB or any similar program when the official update is available, then flash back stock (no root) and update, afterwards simply restore your normal (non-system) apps and your ready

I'm in Aus too, but the official story (courtesy of Telstra) is that there won't be any updates as of JB 4.1.2, unless there's sufficient backlash ...

To answer you and the gentleman above... Australia will probably be the last country on earth to get the update as usual. So we might have to reside to getting it of some kind developer who uploads it here somewhere.
If you do wish to get updates you should go back to stock firmware (probably the first backup you made for your telstra 4.1.2) doesn't matter if it's rooted. Connect your phone to the PC and have KIES installed. Click update firmware and update (done, it will automatically unroot your phone and put back the stock recovery). You can easily update after that.
If anyone finds any android 4.3 working please update us here as soon as you can with a link to the page. If I find a working ROM for the official android 4.3 TW ROM I'll post it here too.

I don't think Aussie tel companies will well I don't have high hopes when it comes to Samsung I've always had HTC and Samsung and it's always the same get f all. I'm using 4.3.1 carbon I use GMD spen features for spen control and gestures don't use stock Sammy apps anyway.. just the 4.3 would be good because it's smooth as

Well now...I've been holding off playing with rooting my phone (as I'm new to 'droid and have an awful lot to learn, but have come a LONG way in 2 weeks) as I was expecting Telstra to release an update. Since that appears NOT to be forthcoming, Ill consider the various root options, none of which are particularly appealing at the moment mainly as it seems no-one has a stock ROM for this phone online and I can't backup mine without root. Catch 22 it seems. Information on locked bootloaders, Telstra ROM mods, rooting the 7105 "T" version is VERY limited
So...if anyone happens to have a link for a ROM copy please let me know.
(Or info on a rooting technique that works)

Ultimately every one on xda will be using the custom 4.3 rom for the note 3 goodies because Samsung will not be releasing those features in it's official release

Okay I will explain what I done for you...
When I first rooted my Galaxy Note 2 in May, I was a new-comer to android, I had an iPhone for a long time. What I done was root my phone, I Odin installed TWRP after rooting because I really don't like CWM (those are the names of the 'recoveries' available), they will replace the default Samsung recovery. Just make sure you get TWRP. I think it's up to TWRP 2.6.3
Well yeah let's get back to the topic, as soon as I rooted I used TWRP to make a backup of my default Telstra ROM (completely with EFS, MODEM, basically tick everything you can possibly backup).
I took that backup and put it on my laptop and on my PC and I kept a copy on my external card the whole time. That was the best idea, any time I ever had any problems with my phone I went back to that backup. I even soft bricked my phone once and after hours of panicking I realised I can just Re-install the default backup, and it fixed my phone.
Oh and I just recently un-rooted my phone to check for updates. All I done was use SuperSU to do an UNROOT. Then went into recover, restored the original backup I made of the Telstra ROM. Plugged my phone into the PC, and used Samsung KIES to check for firmware update. It just restarted my phone, removed TWRP recovery, re-installed the samsung one, and it removed the root completely and I'm basically went back to my original telstra ROM. I can go into settings and check for updates and everything. (I can confirm there is no update as of yet).
AS for your other QUESTION.
ALL THE ROMS in the N7105 Section will WORK with your N7105T Model. It's the same thing. JUST WATCH OUT and make sure you never install N7100 ROMS (They will soft-brick and could hard-brick your phone).

Thanks for the input.
I've been considering between 3, namely CF AutoRoot, Galaxy Note Toolkit And (exploit based) Framaroot, with a bias towards Toolkit so far ( as it specifies the 7105 "T" variant).
But if you've actually ODINed a GT-7105T (Telstra) with CWP without issues, I'll certainly consider that.
Any one else care to chime in on this (if you've done the same phone/telco only though !)
I've come far enough to understand rooting,boot processes, CWM/TWRP, exploits AND the importance of picking the exact model !:laugh:
I'll take the plunge when I get enough input to decide.

It's not that hard really, you can't really mess it up if you follow the instructions... Hey root it whichever way you see fit, whatever you think is easier for you, don't listen to me. But I do highly recommend you get TWRP for backing up and formatting and installing your ROMS. Also I recommend PAC-MAN it's a good ROM, but it's not very stable at the moment (kind of).

Sammobile: 4.3 is rolling out for the S3.

Tried two roms, getting the 'com.android.phone' has stopped responding (immediately)

I've tried Paranoid Android 4.6 and CM 11, both with the same result.
I could not get any custom bootloader to install, aside from safestrap. This seems to be on there ok now, and I can install PA or CM roms from my sd card.
When they are finished installing though (along with Gapps), when it boots into the OS I instantly get the popup telling me the process com.android.phone has stopped. I hit ok and it comes back immediately, no matter how many times I hit it. I can't get into the menus or setup screens, the popup comes back instantly.
Since PA and CM both did this same thing, I am guessing my problem is perhaps not the rom. Any ideas please on what I might try next? The phone is basically bricked at this point.

Yea, you can't flash cm or pa on your device. They can only be flashed on devices with the mdb or mdl bootloader. If you're using safestrap, and it's the only recovery you can use, you're probably on 4.4.4, nb1 or nc1 or nj4, bootloader. You'll need tw based roms. See the ones that work with safestrap.

Thank you,
I flashed to NJ4 after rooting. Could you recommend any custom rom that is tw based please, or am I basically limited to stock?
I tried flashing a new TW rom but now I'm stuck in a recovery mode bootloop (safestrap seems to be gone).

Really appreciate the explanation, thanks again.

Your stuck to 4.4.4 unless you do the method mentioned on the forums and GoldenEye comments.
But a caution its not for the new, is risky and you lose the safestrap recovery boot because safestrap is not lollipop compatible right now.

Got it. Thank you.
I finally found a 'stock' firmware that I managed to load via Odin. Looks like AT&T just pushed the lollopop update to my phone as well so I guess stock lollipop will work for me until I upgrade my phone.
Out of interest, I'm looking at the oneplus one phone. Am I correct in thinking I should have way less problems trying to root & install custom roms on that, since it comes loaded with CM and the carrier isn't going to be constantly fixing exploits that allow root?
Really appreciate the help guys, thanks again.

I don't own it so I couldn't tell you but I would look up the forum for it before hand and see what they say about it.
If it's not an ATT and Verizon phone most likely it's not boot loader locked.

Oneplus you will be able to root and recovery, I believe even unlock the bootloader. You just have to pay full price of the phone of course, but it's separate from carrier so no root patching OTAs.

Awesome. Thank you so much guys. I think I'm going to try out the oneplus one. Sounds like it'll be a lot more straightforward than with AT&T's devices.

Of course we can get your started but see
But first you must answer us these question three.
Why do you want root?
Do you have a computer? (This is a must for root.)
Are you ready to be disappointed?

https://forum.xda-developers.com/tmobile-s7-edge/how-to/how-to-root-s7-edge-t3410470
follow this (use odin to flash rooted kernel) ......you should search before posting things like this.....google is your friend bro.
GOOD LUCK - BTW use flash fire app in play store to make backups and flash roms

Okay okay.
A quick glance at T-Mobile Samsung Galaxy S7 Edge Guides, News, & Discussion would have led you to the "How to root the S7 EDGE" thread.
I'd take a look in there if I were you.

But first you must answer us these question three.
Why do you want root?

Well while I was waiting I just rooted it. So what do you think that would be the next step towards installing a rom? To answer your survey questions :laugh: :
1- Because a phone without being rooted is like a bird without wins.
2- I do
3- Oh well... tell me more

EDIT: I just checked and the root didn't go through... even though ODIN said it was successful

Well then.
Rooting the phone (as I'm sure you had already found out) was fairly easy.
BUT... since we do not have an unlocked bootloader then we cannot have any custom recovery. Which means we can only (for now) use adb and Fireflash to flash any custom firmwares. And while we're on the subject of that... there is only one custom rom. Well... technically there are two but only one for you since you updated to the latest firmware.
Echoe ROM which was updated (ummm...) September 9th (not including the Verizon version which might work but with no promises)
Tekxv2 which was updated back in July. Unfortunately, that is flashed by adb (computer required) and only supports G935TUVS3APD8 which is... pretty old.
Things that you may notice with root.
Battery life may be shorter.
Strange icons on your status bar.
Might start to have random reboots for absolutely no reason.
Can't use Samsung Pay and some other apps.
Phone might be laggy.
Phone might feel hot.
Some of those can be resolved by flashing the only custom rom that we have (Echoe ROM... which is a rather nice rom) but it's not "there" yet.
Or you can use the guide in my signature to resolve issues like the lag and the strange icons. Yet even after the "fix" you might still experience both again from time to time.
You might even have the IMS force close issue which I used to get about once a month. It would piss me off because no sooner that you click the button, it'll pop up again and you don't have time to do anything. You're pretty much forced to reflash stock, wipe, re-root, restore a latest backup... which can take hours and is rather inconvenient if it happens to you while you're at work like it always seemed to happen for me.
SO...
All in all... root is okay. It's better than nothing I suppose. But until we get more developer support for this phone then in my opinion it's kinda pointless in my opinion.
Too many drawbacks. I eventually unrooted two weeks ago and I love my phone now. I'm using the heck out of Samsung Pay especially since their promotions are pretty nice right now! Plus a few members are testing the Nouget update which probably won't be getting root at all since rooting requires an engineering kernel which we don't have and might not get. Or an unlocked bootloader which we've pretty much given up on.
A lot of members that are testing the Nouget beta firmware are extremely satisfied with it so if we can't root Nouget then having a rooted S7 will probably fade away as more people update to Android 7+. That's where I see this going anyway.

So for what I understood the dev support for this phone is very limited... I know the issues I may encounter, I had them with the galaxy note. but any way... If something I'll unroot it but I want to try it out Thank for you time. I've rooted it.
EDIT: Damn... I really don't like the visual style of Echoe... is that one the only one I can flash??

How are you doing with the ads? Like youtube, pandora, spotify? I just installed xposed and the phone feels very hot, and If I unroot it (which I'm thinking to do) I won't be able to get things without ads (I know about vpns and browsers). Also how can I install teaks for apps? Installing apks from pages that promise you this and you have to log in is very untruthful. Any suggestions to all this?

I just put up with them.
In all reality, I don't use my phone for the purposes that require my viewing of ads to begin with.
Sure when I was rooted I had adblocker. But honestly, I had completely forgotten all about that benefit of being rooted until now.
I suppose if you absolutely need to be rid of ads then by all means, retain root. However ads don't effect my daily use one bit.

I just flash the appropriate firmware that you had prior to rooting with ODIN.
Never had any issues. Which "guide" are you referring to?

bro now I'm friking out, I followed this guide and when I click in flash it says Fail. I followed it step by step, I don't don't what's going on and when I reset the phone it says custom and doesn't even load, so tmobil would know that I rooted it...
fff.... can you give me the link, guide, whatever you used to revert it?

You're probably trying to flash a firmware with a V3 bootloader over G935TTMB4APK1.
If you were seriously following that (outdated) guide step by step then you tried flashing TMB_G935TUVU3APG1.zip over a PK1 firmware. Yeah... that doesn't work.
Download the latest firmware from sammmobile.
https://www.sammobile.com/firmwares/database/SM-G935T/
Try it again.
IF that doesn't work... try using Smart Switch.
I haven't done it before but I think it's the Emergency Software Recovery and Initialization.

You have no idea the help you gave me. I went to sammobil before but since it said that the download speed was too slow, I didn't do it through that page. Now I did it and it's working fine thanks bro.
But when I start it, it says: custom in the log in, how can I totally put it original?

If I want to remove everything and just leave it plain how it comes from factory when you buy it, do I just flash the AP file?

You should flash everything.
BL= Bootloader (which should be V4 since you updated to the latest firmware already. Anything less than V4 will fail.)
AP= Is for System, Cache, kernel, etc.
CP= Is for modems
CSC is for your HOME_CSC_TMB_G935TTMB4APK1_CL9507190_QB11413830_REV02_user_low_ship_MULTI_CERT.tar.md5 file.
Important! If you use the CSC_TMB_G935TTMB4APK1_CL9507190_QB11413830_REV02_user_low_ship_MULTI_CERT.tar.md5 (doesn't have the word "HOME" in the name) then it'll wipe your phone!
If your phone still says "CUSTOM" on it then make sure that reboot and check again. If it still says custom then make sure that you don't still have the engineering kernel. Re-flash the AP files again if so. It shouldn't though if it's 100% stock. Also note if you saw the unlocked padlock on the S7 Edge splash screen (before the bootanimation).
Good luck and happy New Year.

Perfect! All I did was reboot it, and the unlocked padlock went away, thank you very much for all your help! Happy new year!
