[Q] Play branded firmware, failed backup, what next?

---

I bought sgs2 few weeks ago, had some fun with stock and samsung apps, then I decided that some changes would be nice

found this great forum, with all knowledge and I have to admit I'm overwhelmed and kinda lost.

rooted my phone with Doomlord method (zerg rush exploit), worked like a charm, installed Titanium Backup, that went smoothly too. From what I understand that didn't change flash counter so I can unroot and keep my warranty in case of hardware problems, am I right?

Then I installed ROM manager and here is where problems started, when I click Flash Recovery it's downloading some file, but when I boot to recovery mode, there is info about e: failed to verify whole-file signature and I can only reboot. If that failed, what did it exactly do with my stock firmware and flash counter? please forgive my noob questions, it's my first android device, I'm reading and learning, but it's a lot to process.

I have branded Play (polish provider) firmware (2.3.3, XWKE7) and I can't upgrade it, cuz I can't backup stock firmware with CWM, I'm afraid to flash without backup in case I need take my phone to samsung.

I would love to at least upgrade to 2.3.5 or try some nice custom roms you guy cook here so skillfully but need some advice any info will be greatly appreciated

Hey hey,

This happens to me too when I installed ROM Manager, and then Flashed a recovery. It does not boot into the orange ClockworkMod Recovery, instead it boots into the stock recovery saying an error.

Don't worry, it did not do anything bad to your phone, it just attempted to install the ClockworkMod recovery but just fails, no biggie All you have to do is flash a custom kernel through Odin, such as CF-Root or Ninphetamine, then you will have ClockworkMod Recovery installed by default. The flash recovery option is for other phones that do not have the secure kernel that Samsung installs into your phone by default.

I use CriskeloROM on my phone, in my opinion, this is my favorite ROM because of the constant updates and massive collection of add ons. It is currently running on 2.3.5 and has a base of XWKJ2. Check out the link in my signature for more details about the ROM.

thank you so much for your answer, good to know I didn't break anything (yet! )

as you advice I will take a look at Criskelo ROM
